The present invention relates to a liquid mixing device in order to mix a first substance which is in liquid form and a second substance which is in liquid and/or powder form where said substances do not dissolve in each other, and comprising a mixing chamber having an upper wall, a lower wall provided against said upper wall, and side walls provided to connect the lower wall and the upper wall in a manner defining a mixing volume.
A homogeneous mixture of insoluble liquids is used in various fields.
In the field of pharmacy, mixtures such as cream, ointment, dental composite, syrup, injection liquid comprise liquid mixtures that do not dissolve in each other.
In the field of cosmetics, products such as cream, lotion, mascara, wax, gel, toothpaste contain insoluble liquid mixtures. The durability of these mixtures without deteriorating its homogeneity affects its expiry dates. Many of these liquid mixtures contain oil and water components. In the current art, chemical additives are used to ensure that such mixtures remain homogeneous for a long time, but these additives reduce the effectiveness of the mixture. In some cases, it may be desirable for the mixtures to be made of 100% natural substances. When additives are added to the mixtures, the mixtures may lose their naturalness. For example, there are Organic farms where cows are fed and raised completely organic materials. In case these cows get sick, it is expected that the applied medications to contain only natural substances and it is requested not to include any chemical additives.
In the present art, it is possible to mix liquids with a rotationally moving mixer by adding two liquids into a mixing chamber. However, when the liquids are mixed by means of this method, the homogeneity lifetime of the mixture is short since the liquids do not break up into small enough droplets. Applications with numbers CN110743435, WO02001056687A1 and CN108371934 mention a device that provides mixing of liquids in a similar way to the method mentioned above.
Mixers of the micro-mixer type are also known in the art. The liquids are forced to hit the walls in the passages at a very high pressure, thus fragmented into pieces. Beside it is not suitable for mass production, it require high consumption of pressure and energy.
As a result, all the above-mentioned problems have made it necessary to make an innovation in this technical field.
The present invention relates to a liquid mixing device and mixing method for eliminating the above mentioned disadvantages and bringing new advantages to the related technical field.
An object of the present invention is to provide a liquid mixing device for homogeneously mixing a first substance and a second substance which do not dissolve in each other and for providing preservation of the homogeneity of the mixture for longer period.
Another object of the invention is to provide a device that enables the production of a mixture with increased efficiency.
Another object of the present invention is to provide a mixing device and a mixing method enabling the preparation of mixture which does not contain chemical additive substance and which can be prepared in a sterilized and/or pasteurized conditions.
Another object of the invention is to present a device that enables the production of mixtures that maintain their homogeneity for a long time without being containing any chemical additive substance.
Another object of the present invention is to provide a liquid mixing device where the addition of liquids and the discharge of the mixture are facilitated.
Another object of the invention is to introduce a liquid mixing device that allows mixing of two liquids which do not dissolve in each other where the amount of unwanted air or oxygen mixed in the mixture is reduced. (Turkish equivalent of this sentence means that mixing is provided where unwanted oxygen or air amount mixed in the mixture is greatly reduced comparing to prior art. Which means, there might still be unwanted oxygen mixed in the mixture but it's a lot lower than the devices that present in the current art. So I fixed it accordingly.) Another object of the invention is to provide a liquid mixing device that allows mixing of liquids do not dissolve in each other to obtain a liquid mixture that maintain homogeneity for a long period.

Thanks to the present invention, particles of substances separates each other while passing through the narrow throat. When they reach the right speed, the amount of passing through and dividing each other increases and they mix with each other homogeneously. Since particles of the same substances that attracts each other are of Nano sized particles they are mixed homogeneously, and homogeneity is maintained for a long period.
The first substance and the second substance which are mentioned in this invention may contain more than one liquid, more than one powder, and may have different densities.
In more details, the mixing chamber (100) comprises an upper wall (110), a lower wall (120) positioned against said upper wall (110) and side walls (130) which connect the upper wall (110) and the lower wall (120) to each other. In this possible embodiment of the present invention, the mixing chamber (100) is in hollow cylinder form. The volume encircled by the mixing chamber (100) is defined as a mixing volume (140).
A piston is provided in the mixing volume (140). A piston rod (300) is provided which provides movement of said piston between the lower wall (120) and the upper wall (110). The piston is associated with the side walls (130) in a sealed manner. The piston divides the mixing volume (140) into two volumes, namely a first volume (141) and a second volume (142). A drive element 500), which provides movement of the piston rod, is provided in association with the piston rod (300). The drive element (500) provides a linear movement.
The piston comprises at least one mixing throat (210). As can be seen in more details in
Pluralities of mixing throats (210) can be provided. With reference to
The piston rod (300) comprises a first body (311) which part of it remains in the first volume (141) and a second body (312) which part of it remains in the second volume (142). Thus, both volumes have a piston body. By implication when the piston is rested to the lower wall (120), the volume difference between the first volume (141) and the first body (311) will be empty; and when the piston is rested to the upper wall (110), the volume difference between the second volume (142) and the second body (312) will be empty. But in case there is only one body (for instance, the first body) (311), so while the first volume (141) can be fully usable, if the piston is resting to the lower wall (120), an extra liquids would have been added to the second volume (142) equal to the volume of the piston rod (300) if the piston is resting to the upper wall (110). In this case, an air gap will be formed or the piston will reach the maximum possible movement point without being rested completely to one of the walls. This will cause some liquid to always remain in the first or second volume (142), and the mixture will not be substantially homogenous.
The upper wall (110) and the lower wall (120) comprises a first body opening (111) and a second body opening (121) for the piston rod (300), this is to enable the piston first body (311) to move from outside to inside or from outside the mixing volume (140) to inside it between the upper face and the lower face of the piston. Piston openings are sealed in relation to piston rods. An upper wall gasket (320) is provided in the first piston opening (111). A lower wall gasket (320) is provided in the second piston opening (121).
At least one upper wall comprises a liquid transfer port (112). The liquid transfer port (112) enabling the addition of the first and second substance (602) to the first and second volume (142). In case the liquid transfer port (112) is at the upper wall (110), the piston can rest against the lower wall (120) and the first and second substance (602) can be added through the liquid transfer port (112). At the upper wall, moreover, an air discharge port (113) is provided. Said air discharge port (113) provides discharge of the air which may remain above after filling the volume (140) with the first substance (601) and the second substance (602). In a possible embodiment of the present invention, the device can comprises a vacuum system (700) associated with the air discharge port (113), a vacuum valve (701) which is controlled by the vacuum system, and a vacuum pump (702).
With reference to
The lower wall delimiter (122) can be fixed to the side walls (130) by means of the connection holes (152), the connection screws (150) which are to be placed to the connection holes (152), and the connection nuts.
One each plugs can be provided for closing the liquid transfer port (112) and the air discharge port (113).
One of the distinctive characteristics of the present invention is the piston movement speed. The piston rod (300) moves with speed and with force so as to move the piston such that the liquid passing through the mixing throat (210) passes with the speed of approximately 100 m/s. When this particular speed and the special dimension of the mixing throat (210) opening are combined, the liquids are separated into Nano-Size particles and mixed within each other, homogeneity of such a mixture is preserved and the storage lifetime is substantially increased when compared with the similar mixtures known in the art. This speed and dimension has been obtained as a result of pluralities of experiments. Said speed can be between 40 m/s and 200 m/s according to the density of the liquids.
By means of the liquid mixing device (10) given in details above, the first substance (601) and the second substance (602) are mixed as follows.
With reference to
The liquid discharge port of the substance chamber (115) is closed by the plug. With reference to
It has been observed that the homogeneity is preserved when the water-oil based active substance mixtures are produced by this device. Moreover, it has been observed that the ointment-like drugs produced by means of this device is much more effective when compared with the similar drugs produced by means of the prior art since the mixture is in the form of Nano-size particles and does not contain additive substance.
The first body (311) and the second body (312) can be connected to each other by means of a first and second body connection (330). The piston (300) comprises a piston rod fixation opening (213) and the first and the second body connection (330) pass through this opening and are connected to the rods.
The subject matter device comprises a temperature control chamber (400). The temperature control chamber (400) is provided in a manner encircling the mixing chamber. The temperature control chamber (400) can comprise outer walls (401) provided outside of the side walls (130). A volume is formed between the side walls and the outer wall. In this volume, heat exchanger (404) is provided which passes through the insulation material (402). Thanks to the liquid pipes (406), liquid is transferred or discharged into/from the temperature control chamber (400). The temperature of the liquid which exists in a temperature controlled liquid tank (405) is controlled and passes through liquid pipes (406) thanks to a pump (403), and the liquid which exists in the mixing chamber (100) is heated thanks to the heat exchanger (404).
The subject matter device is connected onto the drive element (500) by means of the machine assembly elements (510) rising from the drive element (500).
The piston speed can be such that the speed of substances while passing through the mixing throat (210) is between 40 m/s and 200 m/s. This speed changes according to the viscosity of the substances. For instance, the speed of the piston rod can be selected in a manner providing passing of water and oil mixture through the mixing throat (210) with speed of at least 100 m/s.
The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
