When manufacture of components (e.g., a plastic tube) involves a cutting process (e.g., by a drum cutter), dust and debris can be statically energized and cling to these components. A conventional way to remove undesirable dust or debris is applying suitable airflow to these components individually. The undesirable dust or debris can be moved and carried away by suitable airflow. However, the conventional way of removing undesirable dust or debris can be extremely time consuming and thus inefficient. Therefore, improved apparatuses, systems, or methods for removing dust or debris from manufactured components are desirable.
The technology of the present application is directed to an improved apparatus, system, and associated method for removing debris from lightweight components. The improved apparatus can include an air mover, a cyclonic chamber in fluid communication with the air mover, an enclosure component operably attached with the cyclonic chamber, and a debris collection component in fluid communication with the cyclonic chamber. The lightweight components positioned inside the cyclonic chamber can be moved, rotated, or carried by cyclonic airflow, causing the lightweight components to hit against one another or against the sidewall, so as to separate the debris clung thereto.
The technology of the present application also discloses a method of removing debris from lightweight components. The method can include: positioning the lightweight components in a cyclonic chamber; providing an incoming airflow path to the cyclonic chamber along a substantial tangential direction; generating cyclonic airflow in the cyclonic chamber; carrying, moving, or rotating the lightweight components by the cyclonic airflow; removing debris attached with the lightweight components at least by causing the lightweight components to hit against one another or against an inner surface of the cyclonic chamber; and collecting the separated debris by a debris collection component.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary, and the foregoing Background, is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.
These and other aspects of the present technology will be apparent after consideration of the Detailed Description and Drawings herein.
Non-limiting and non-exhaustive embodiments of the present technology, including the preferred embodiment, are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified.
The technology of the present application is described with specific reference to an apparatus for removing debris clung to a plurality of lightweight components. The term “lightweight component” can be defined as components that can be moved, rotated, or carried by suitable airflow. As, as used herein, the terms “debris”, “dust”, “dirt”, or the like are used relatively interchangeably to mean any unwanted particle remaining on the lightweight components subsequent to processing whether the particle remains on the lightweight component due to static electric energy or other adhesion. Moreover, the technology of the present application will be described with relation to exemplary embodiments. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. Additionally, unless specifically identified otherwise, all embodiments described herein should be considered exemplary.
The cyclonic chamber 102 can have an air inlet, an air outlet, and a sidewall. The airflow generated by the air mover 101 can be directed into the cyclonic chamber 102 via the air inlet. The air inlet can be positioned on the sidewall, so as to allow the directed airflow to generate cyclonic (or spiral) airflow inside the cyclonic chamber 102. The cyclonic airflow generated inside the cyclonic chamber 102 can cause lightweight components positioned in the cyclonic chamber 102 to hit against one another or against the sidewall, so as to separate the debris clung thereto.
In one exemplary embodiment, the cyclonic chamber 102 can have a bucker shape whose volume is around 5 gallons. An exemplary operating time of separating or removing debris, for example, can be 30 seconds. An exemplary number of lightweight components that can be position in the cyclonic chamber at one time can range up to about 200 to 225 parts. In other embodiments, the volume of the cyclonic chamber 102, the operating time of separating or removing debris, and the number of lightweight components can vary depending on multiple factors, such as the sizes and/or materials of the lightweight components, efficiency of the air mover 101, the size and/or shape of the cyclonic chamber 102, or required cleaning results.
The debris collection component 103 is in fluid communication with the cyclonic chamber 102 via the air outlet. The separated debris can be carried by airflow leaving the cyclonic chamber 102 and then can be collected by the debris collection component 103. In some embodiments, the debris collection component 103 can be a debris collection chamber (or a catch box) that can collect debris carried by passing airflow. For example, the debris can be collected by deposition, screening, meshing, or other suitable means. In other embodiments, the debris collection component 103 can be a filter designed to remove the carried debris. In still other applications, the debris collection component 103 is optional and the system may exhaust to atmosphere.
The controller 104 can be coupled to the air mover 101, the cyclonic chamber 102, and the debris collection component 103. The controller 104 can include a processor and a memory. In some embodiments, the controller 104 can monitor the statuses of the air mover 101, the cyclonic chamber 102, and the debris collection component 103 by receiving signals from suitable sensors. In other embodiments, the controller 104 can adjust the operation of the air mover 101, the cyclonic chamber 102, and the debris collection component 103 based on the received signals. For example, the controller 104 can increase the airflow generated by the air mover 101 when the controller 104 detects that the cyclonic airflow in the cyclonic chamber 102 is insufficient to move, rotate, or carry the lightweight components positioned therein. In another example, the controller 104 can decrease the airflow generated by the air mover 101 when the controller 104 detects that a debris-removing efficiency of the debris collection component 103 is below a certain threshold (e.g., providing more time for the debris collection component 103 to collect the separated debris).
In the illustrated embodiment, the cyclonic chamber 300 can include an air inlet 304 and an air outlet 305 both positioned on the sidewall 303. The air inlet 304 can be positioned at a first height H1 of the sidewall 303, and the air outlet 305 can be positioned at a second height H2 of the sidewall 303. In the illustrated embodiment, the first height H1 is lower than the second height H2. In some embodiment, the first height H1 can be higher than the second height H2. In other embodiments, the first height H1 and the second height H2 can be substantially the same. Also, while shown in the sidewall 303, the air inlet 304 and air outlet 305 may be positioned on either the top or bottom surfaces 301, 302.
In the illustrated embodiment, the air inlet 304 can be a rectangular opening, while the air outlet 305 can be a slot. The slot can have a width less than the dimension of individual lightweight components, so as to prevent individual lightweight components from leaving the cyclonic chamber 300 through the slot. In other embodiments, the air inlet 304 and the air outlet 305 can be in other suitable shapes, such as circles or polygons. Also, rather than a simple opening, the air inlet 304 may include a nozzle, jet, filter, perforations, or the like. Similarly, the air outlet 305 may include a screen, mesh, cover, flap, or the like.
With reference to
The cyclonic airflow path A2 can travel inside the cyclonic chamber 300 from the air inlet 304 to the air outlet 305. In the illustrated embodiment, the cyclonic airflow path A2 can include an upward-spiral airflow path (as oriented and view on
The exhaust airflow path A3 can start from the air outlet 305 of the cyclonic chamber 300 to ambient air, passing through the debris collection component (e.g., the debris collection component 103 or 202). The separated debris can be carried away along the exhaust airflow path A3 and collected by the debris collection component. The debris collection component can be a filter, collection chamber, catch box, or any other suitable means.
In the illustrated embodiment, the cyclonic chamber 400 can include an air inlet 404 and an air outlet 405. The air inlet 404 can be positioned on the sidewall 403. The cyclonic chamber 400 can include a wire mesh 407 positioned at the air outlet 405 on the bottom surface 402 of the cyclonic chamber 400. The wire mesh 407 can facilitate retaining the lightweight components in the cyclonic chamber 400. In other words, only separated debris can be carried by airflow passing through the wire mesh 407. In other embodiments, the wire mesh 407 can be replaced by a screen, sieve, strainer, sifter, or the like.

At block 803, the method 800 can proceed by generating cyclonic airflow in the cyclonic chamber. The cyclonic airflow can include an upward-spiral airflow path (e.g., A2 in
At block 804, the method 800 can proceed by carrying, moving, or rotating the plurality of lightweight components by the cyclonic airflow. The lightweight components positioned in the cyclonic chamber can be moved, rotated, or carried by the cyclonic airflow along the cyclonic airflow path. At block 805, the method 800 can continue by removing debris attached with the plurality of lightweight components at least by causing the plurality of lightweight components to hit against one another or against an inner surface of the cyclonic chamber. Vibration caused by the impact or clash among the lightweight components can effectively remove or separate undesirable debris attached therewith.
At block 806, the method 800 can end by collecting the removed debris by a debris collection component. Once the debris is separated, it will be transported outside the cyclonic chamber by exhaust airflow (e.g., A3 in
