Modularized paint-mist filtering device

Abstract

The invention discloses a modularized paint-mist filtering device.The modularized paint-mist filtering device comprises an air inlet section, a filtering section and an air outlet section.The air inlet section comprises an air inlet and a flow-disturbing and flow-equalizing bin.The air outlet section comprises an air outlet and an air outlet bin.The filtering section comprises a movable frame detachably and correspondingly embedded and positioned between the flow-disturbing and flow-equalizing bin and the air outlet bin, a filtering part arranged in the movable frame and rapid-disassembling locking mechanisms arranged between the movable frame and the flow-disturbing and flow-equalizing bin and between the movable frame and the air outlet bin respectively.According to the filtering device, the negative-pressure type design is adopted, air with paint mist sequentially passes through the air inlet section, the filtering section and the air outlet section, a body of the filtering part is separated from the detachable movable frame, and the movable frame with the filtering part can be conveniently pulled out and replaced; the movable frame and the body are locked through the rapid-disassembling locking mechanisms, disassembling and assembling are quite convenient, and replacement is completed within 3 minutes; online production-type replacement can be achieved by closing inlet-outlet valves of the filtering device, and the defect that as for dry filtering, a filter can not be replaced during production is overcome.

Description

technical field [0001] The invention relates to the technical field of automobile painting, in particular to a modular paint mist filtering device. Background technique [0002] The traditional paint mist exhaust gas separation technology is mainly divided into two types: dry type and wet type. Although the traditional wet Venturi flume, water cyclone and water curtain technology can achieve continuous separation of paint mist and meet the needs of continuous operations in large batches, this technology will generate a large amount of waste and waste liquid, and because The humidity of the exhaust air is high and dehumidification requires energy consumption, so the energy saving effect of recycling is not obvious. In recent years, some foreign companies have also developed some new dry separation technologies, such as using lime powder to capture overspray paint mist, and then relying on filtration technology to separate solids and gases. This technology consumes a lot of l...

Problems solved by technology

Although the traditional wet Venturi flume, water cyclone and water curtain technology can achieve continuous separation of paint mist and meet the needs of continuous operations in large batches, this technology will generate a large amount of waste and waste liquid, and because The humidity of the exhaust air is high and dehumidification requires energy consumption, so the energy saving effect of recycling is not obvious

In recent years, some foreign companies have also developed some new dry separation technologies, such as using lime powder to capture overspray paint mist, and then relying on filtration technology to separate solids and gases. This technology consumes a lot of lime powder and contains a lot of paint. Lime powder forms new solid waste that needs to be treated, resulting in increased treatment costs

There are also companies that use electrostatic paint mist separation technology, but this system has the problem of being easily adhered by sprayed objects and difficult to remove

In addition, these devices are complex in structure and expensive, and have been gradually abandoned by automobile painting production lines.
