Vacuum spraying and filtering device

Abstract

The invention provides a vacuum spraying and filtering device, which is characterized by comprising a primary filter box, a secondary filter box and a vacuum pump; air containing paint is introduced into the primary filter box, the primary filter box is communicated with the secondary filter box through a pipeline, the secondary filter box is connected with the vacuum pump through a pipeline, a plurality of filter plates are longitudinally arranged in the primary filter box at intervals, a plurality of filter holes are formed in the surface of each filter plate in a penetrating mode, the secondary filter box is divided into three filter zones in a vertical direction, a plurality of filter blocks are arranged on each filter zone in the vertical direction at intervals, and the air containing the paint enters from the top of the first filter zone, exits from the bottom of the adjacent second filter zone, and then exits from the top of the third filter zone to form an S-shaped air flower direction. The vacuum spraying and filtering device disclosed by the invention has a better filtering effect, so that raw material waste is less, and environmental pollution is less; furthermore, the vacuum spraying and filtering device is easy to assemble and maintain.

Description

technical field [0001] The invention relates to the technical field of environmental protection devices, in particular to a vacuum spraying filter device. Background technique [0002] When the sprayer sprays UV paint, the paint mist containing UV paint enters the filter assembly of the sprayer along with the high-pressure wind for filtration before being discharged into the atmosphere. However, the filtration effect of most sprayer filter assemblies cannot meet the requirements, which not only wastes UV paint raw materials, but also pollutes the air. At the same time, most sprayer filter assemblies are cumbersome to assemble and maintain, and are not easy to clean, so it is necessary to improve them. Contents of the invention [0003] In view of the above problems, the present invention provides a vacuum spraying filter device, which has better filtering effect, less waste of raw materials, less environmental pollution, easy assembly and maintenance, and convenient clean...
