Powder recycling filter of powder spraying production line and using method thereof

Abstract

The invention relates to the field of spraying equipment, in particular to a powder recycling filter of a powder spraying production line and a using method thereof. The powder recycling filter comprises a filter body which comprises an equipment layer, a filtering layer and a collecting layer sequentially from top to bottom, an air extractor, a motor and an air compressor are arranged inside theequipment layer, a double-filter-element group is arranged inside the filtering layer, the upper end of the double-filter-element group is rotatably connected to the upper end of the filtering layer through the motor, an air incoming airway is arranged on the lateral side of the filtering layer, the collecting layer is in the shape of an inverted boss, diameter of the upper end of the collecting layer is identical with that of the filtering layer, and a powder barrel is arranged at the lower end of the collecting layer.

Description

technical field [0001] The invention relates to the field of spraying equipment, in particular to a powder recovery filter for a powder spraying production line and a use method thereof. Background technique [0002] Powder recovery equipment is installed in the spraying industry, and then the powder with larger particles is collected and reused, and some fine particles are processed through the filter device. However, when the current filter device is filtering, the filtered fine particles often adhere to the On the filter net, after being accumulated to a certain extent, the filtration efficiency of the filter will be greatly reduced, so it needs to be processed manually, resulting in a reduction in production efficiency. [0003] For example, a kind of dust removal and recovery device with a graded filter and a filter element reported in Chinese patent literature, its application publication number is CN107930261A: the described dust removal and recovery device with a gra...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems in the prior art that the filter element in the recovery filter is easy to accumulate dust, the filtering effect is poor, and manual cleaning is time-consuming and labor-intensive, which easily reduces production efficiency, and provides a method that can automatically clean the dust accumulated on the filter element. The filtering effect is greatly improved, a kind of powder recovery filter for powder coating production line and its use method can be effectively improved without manual operation and production efficiency
