A container steam heating system includes a heat source, a distribution component and a heating component, the heat source includes a steam generator, and the heating component includes a heating plate 3 arranged on the bottom of the container, and an object to be heated, such as a liquid bag, can be placed on the heating plate 3. In order to fully and evenly heat the liquid bag and the like, the heating plate 3 is a hollow plate with a number of through-grooves 1 opened inside. The steam of the generator is distributed into all the through grooves 1 of the heating plate 3, and the steam heats and maintains the heating plate 3 and its upper heating object in the through grooves 1. The through-grooves 1 in the embodiment may be arranged in parallel with each other and arranged at equal or different intervals.
In one of the embodiments, the through groove 1 extends along the length direction of the container. The height inside the container is the distance from the bottom surface of the box to the bottom of the top plate, the width is the distance between the two inner lining plates, and the length is the distance between the inner plate of the box door and the inner lining plate of the end wall. Most of the containers are of standard specifications, and the through groove 1 extends along the length of the container to facilitate the introduction of steam from the outside, such as from the door of the container, and the steam is evenly distributed at the bottom of the container to thoroughly heat the interior of the container.
In one embodiment, the heating plate 3 includes a head portion connected to the distribution assembly and a tail portion opposite to the head portion, and the through slot 1 inputs steam at the head portion of the heating plate 3 and outputs steam at the tail portion of the heating plate 3.
In one of the embodiments, the through groove 1 is connected to the inner space of the container from the end of the heating plate 3, that is, the through groove 1 passes through the entire heating plate 3 and is not closed at the end, and directly communicates with the outside of the heating plate 3. In different embodiments, the through groove 1 can be closed at the tail if it is necessary to retain steam.
In one of the embodiments, at least part of the tail of the heating plate 3 is bent upwards, so that the tail of the heating plate 3 produces a chimney effect, which is conducive to the diffusion of steam into the container.
In one embodiment, the heating plate 3 is provided with a groove, the groove is opened in the width direction of the heating plate 3 (i.e., the width direction of the container), and the tail of the heating plate 3 is bent upward along the groove, which is convenient to form an L-shaped tail shape, the through groove extends to the bent heating plate, and the steam is exhausted upwards after reaching the rear of the heating plate 3. In one embodiment, the grooves are V-grooves.
In one of the embodiments, a connecting gas pipe is also included, the heating plate 3 has at least two, and the two ends of the connecting gas pipe are respectively connected to the through grooves 1 of different heating plates 3. A plurality of heating plates 3 are connected or separated, the heating area can be adjusted, and the use cost of the steam and the steam generator can be saved. In one embodiment, the heating plates 3 are arranged side by side, and the two ends of the connecting gas pipes are respectively connected to the through grooves 1 of the adjacent pair of heating plates 3.
In one of the embodiments, the heating plate 3 includes a head part connected to the distribution assembly and a tail part opposite to the head part, and the connecting gas pipes connect the adjacent heating plates 3 end to end in turn to form a steam-circulating heating system. The heating plate 3 can be further communicated, and the steam realizes a complete internal circulation, which not only saves energy, but also prevents the influence of the external environment.
In one of the embodiments, there are at least two heating plates 3, which are arranged side by side or side by side on the bottom plate of the container, there is no communication relationship between the heating plates 3, and they are only laid flat on the bottom of the container.
In one of the embodiments, the distribution component is a high temperature resistant plastic part 2 which is hollow inside. The plastic part 2 includes an inlet end communicated with the steam generator and a plurality of outlet ends communicated with the through grooves 1 in a one-to-one correspondence. A plastic part 2 is used to connect the steam input pipe of the steam generator and the heating plate 3, so that the input steam enters the through groove 1 and passes through the whole heating plate 3, so as to maximize the heating surface and improve the heating efficiency.
The through groove 1 communicates with the plastic part 2 and the inner space of the container. The heating plate 3 or the steam heating pad is laid before loading or stacking the goods, and then the whole hollow heating plate 3 can be heated by inputting steam and conduct heat to the goods above, so as to achieve the purpose of heating the goods above. The steam is released into the inner space of the container through the opening at the end of the bent portion of the heating plate 3.
In one embodiment, the heating plate 3 includes a top plate, a bottom plate horizontal to the top plate, and a pair of side plates respectively connecting the top plate and the bottom plate. A number of partition plates are also arranged between the top plate and the bottom plate, and the partition plates are vertically fixed on the top plate and the bottom plate. It not only supports the top plate, but also separates the space enclosed by the top plate, the bottom plate and the side plate into a plurality of through grooves 1.
In one of the embodiments, the splicing assemblies are fixed on the side plates, and the splicing assemblies on different heating plates 3 are connected to each other so that the heating plates 3 are connected side by side with each other. Of course, different heating plates 3 can also be directly laid side by side on the bottom of the container, for example, two or three heating plates 3 can be laid side by side to cover the bottom of the container. In one embodiment, the splicing assembly includes a latch lock, and a pair of side plates of the heating plate 3 are respectively fixed with a latch lock sleeve and a lock rod corresponding to the lock sleeve. The locks lock against each other to prevent displacement.
In one of the embodiments, the heating plate 3 has a groove 4, and the heating plate 3 can be folded along the groove 4. The grooves 4 can be opened along the length or width direction of the heating plate, so that the heating plate 3 can be folded from different directions to suit different space laying requirements. Since the heating plate 3 has a large area, the folded heating plate 3 is convenient for storage and transportation when not in use. For example, the groove 4 is V-shaped: when the heating plate 3 is folded up along the groove 4, the steam can be discharged upward; after the heating plate 3 is reversely folded along the groove 4, the heating plate 3 can be completely folded for storage and transportation. In addition, the opening of the grooves 4 can also provide flexibility for the heating plate 3, and the heating plate 3 can be slightly bent to adapt to the undulating laying surface. After the above-mentioned groove 4 is opened, the through groove 1 exposed at the groove 4 can be further closed to prevent the steam from flowing out of the groove 4. Or keep it as it is, the steam can flow out from the groove 4, and the groove 4 opened according to the needs can increase the steam outlet, and the released heat can heat the goods above the place.
In one embodiment, the plastic part 2 is provided with a number of switches, which correspond to the gas outlet end one-to-one and control the opening and closing of the gas outlet end, so as to facilitate the adjustment of the on-off of the steam in the through groove 1 and finely manage the heating of the goods. In one of the embodiments, a control assembly is also included, and the control assembly is connected to and controls the steam generator and the opening and closing of the switch.
