[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0028] Example 1

[0029] refer to Figure 1-2 As shown, a draining device for a filter element of a paint system comprises: a filter element cylinder 10, a negative pressure unit 20, and a paint recovery box 30. A filter element frame 40 for placing a filter element is provided in the filter element cylinder 10, and the filter element frame 40 comprises a draining net 41 densely covered with hollow holes, and a center rod 42 fixed on the draining net 41. The filter element frame 40 of the utility model is made of stainless steel and is not easy to rust.

[0030] The negative pressure unit 20 of the utility model is connected to the top of the filter cartridge body 10 through a pipeline to suck the volatile vapor in the filter cartridge body 10. Generally, the evaporation performance of the paint is not high, so the negative pressure unit 20 can use a slight negative pressure. An exhaust gas treatment module 50 is also connected to the end of the negative pressure unit 20 to treat the escaped paint vapor. For example, the exhaust gas treatment module 50 uses an aqueous solution containing a cleaning agent to absorb the paint vapor.

[0031] The paint recovery box 30 of the utility model is placed at the bottom of the filter cartridge body 10 for recovering dripping paint. In order to facilitate the collection of paint, the lower part of the filter cartridge body 10 has a closed opening 12, and the structure of the closed opening 12 can reduce the volatilization of paint at the same time.

[0032] The height of the center rod 42 of the utility model does not exceed the height of the filter element cylinder 10, and a handle 43 is provided on the top of the center rod 42 for easy transportation.

[0033] The specific usage process is as follows:

[0034] First, open the sealing cover 11 of the filter cartridge body 10, take out the filter cartridge holder 40, and place the filter cartridge to be drained on the filter cartridge holder 40, then place the filter cartridge holder 40 into the filter cartridge body 10, cover the sealing cover 11, turn on the negative pressure unit 20, and wait for the filter cartridge to be drained.

[0035] Since an exhaust gas treatment module 50 is also connected to the end of the negative pressure unit 20 to treat the escaped paint vapor, it can avoid polluting the environment and is beneficial to environmental protection. The filter element cylinder 10 adopts a closed-end 12 structure, which can reduce the volatilization of paint and effectively recycle the paint through the paint recovery box 30 at the bottom to avoid waste.

[0036] Example 2

[0037] refer to Figure 3-4 As shown, different from the embodiment 1, the filter element frame 40 further includes three filter element support rods 44, which are fixed to the outside of the center rod 42, and the height of the filter element support rods 44 is not greater than the height of the center rod 42. By providing a plurality of filter element support rods 44, a plurality of filter elements can be drained at the same time.

[0038] Compared with the prior art, the utility model provides a draining device for a filter element of a paint system, which has the following beneficial effects: a simple and reasonable structure, the filter element is placed in a closed filter element cylinder 10 for draining, which is convenient, fast, and hygienic, and can effectively recycle paint to avoid waste; at the same time, through the negative pressure unit 20 and the exhaust gas treatment module 50, the escaped paint vapor can be effectively treated to avoid environmental pollution, which is beneficial to environmental protection.
