The air-drying device blows air on the aluminum plates passing through so that they can be dried quickly. At the same time, in order to avoid blowing the floating dust in the air onto the aluminum plates when blowing, a filter plate needs to be installed in the air supply duct used by the aluminum plate air-drying device to filter the floating dust in the air. However, long-term filtration can easily cause a large amount of dust to accumulate on the filter plate, affecting the air-drying efficiency of the aluminum plates, so it needs to be checked and cleaned regularly.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-3 As shown, the utility model provides an auxiliary filter for an aluminum plate air-drying device. The filter screen in the auxiliary filter can be cleaned of dust without disassembling the auxiliary filter, while ensuring the normal operation of production.

[0022] The filter is similar to the prior art in that it includes an air supply duct 1, one end of which is connected to the air outlet of the fan, and the other end of which is aligned with the moving path of the aluminum plate. The airflow generated by the fan is guided by the air supply duct 1 to air-dry the aluminum plate on the production line.

[0023] The difference between the filter and the prior art is that the air supply duct 1 is provided with a filter 4 for filtering floating dust, and the air supply duct 1 is provided with two perforations 6 that penetrate the air supply duct 1 horizontally, and one end of the filter 4 passes through the two perforations 6 in sequence and is connected with the other end thereof, so that the filter 4 can form a rotatable ring shape, and at the same time, the filter 4 is provided with two support rollers 3 that support the filter 4 to rotate on the inner side of the two side ends of the air supply duct 1, and both ends of the support rollers 3 are rotatably arranged on the air supply duct 1 through the fixing blocks 8. The filter 4 is supported by the support rollers 3 to rotate, so that it can rotate. When it is necessary to clean the filter 4 located in the air supply duct 1, it is only necessary to control the rotation of the filter 4, so that the filter 4 located in the air supply duct 1 can be partially moved to the outside of the air supply duct 1, so as to clean it. Without disassembling it, the dust accumulated on the filter 4 can be cleaned, and the normal operation of production can be guaranteed at the same time.

[0024] In order to increase the area of ​​the filter 4 that can be cleaned at one time, the distance between the two support rollers 3 on one side of the air supply duct 1 is made larger than the distance between the two perforations 6, so that a cleaning station for cleaning the filter 4 is formed on that side. When the filter 4 passes through this side, the part of the filter 4 located on this side is cleaned.

[0025] One side of the air supply duct 1 located at the cleaning station is provided with two guide rollers 10 respectively fitted with the upper and lower outer sides of the filter screen 4, and the guide rollers 10 are respectively located at the two perforations 6. The guide rollers 10 make the filter screen 4 rotate more flexibly at the turning position.

[0026] The surface of the support roller 3 is provided with an anti-skid layer, which can prevent the filter screen 4 from moving easily, and prevent the filter screen 4 from being dragged when the filter screen 4 is cleaned with a brush, which causes inconvenience in cleaning. The anti-skid layer is an elastic rubber pad sleeved on the support roller 3. The anti-skid layer is friction particles.

[0027] A rotating brush roller 7 is provided on the outer wall of the air supply duct 1, and the bristles of the brush roller 7 are in conflict with the filter 4. If there is not much dust on the filter 4, the filter 4 only needs to be controlled to rotate, and when the filter 4 passes the brush roller 7, the brush roller 7 will remove a small amount of dust on the filter 4.

[0028] In this embodiment, an observation window 9 is provided on the air supply duct 1 for viewing the state of the filter 4 inside the air supply duct 1, so as to facilitate understanding whether the filter 4 needs to be cleaned.

[0029] In this embodiment, the ends of the filter 4 on both sides of the air supply duct 1 are covered with dustproof frames 2, which can prevent dust in the external air from entering the sides of the filter 4 and causing pollution to the filter 4.

[0030] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention.
