Description

TECHNICAL FIELD

[0001] The present application relates to the field of environmental protection equipment, and in particular to a vertical self-renewing paint mist filter winding and unwinding device. BACKGROUND

[0002] Spraying operations are common in various factories and are a common production link in manufacturing. During the spraying of parts, paint mist waste gas is generated. In the context of the increasing development of environmental protection, it has been stipulated that industrial waste gas must be purified and treated to meet the standards before being discharged into the atmosphere.

[0003] In order to collect and treat paint mist waste gas, and also for economic reasons, some enterprises now use automatic filter cotton replacement spool filters. Most of these filters are horizontal spool filters with a horizontal main shaft. The filter structure is simple and suitable for use in small filter aperture applications. Some are horizontal spool filters with a vertical main shaft. The filter surface and filter aperture of this type of filter are easy to adjust and can be used in large filter aperture applications. However, the replacement steps of the filter roll are complicated and difficult to maintain.

[0004] The disclosed utility model patent "Automatic replacement filter cotton front dry filter" (Chinese patent authorization announcement number CN 211462504 U) discloses an automatic replacement filter cotton front dry filter. The filter cotton roll in this device is vertically placed, and the overall structure is simple. This solution is general and does not consider the problems that may arise in actual application.

[0005] Among them, the problem of how to replace the vertically placed filter roll is described simply in the comparative document, which does not elaborate on the detailed replacement scheme and process. The filter roll needs to be disassembled from the equipment shell when replacing the filter roll. The shaft for installing the filter roll in the main body of the equipment is not designed with movable parts or a structure that can be disassembled separately, which makes it necessary to insert the filter roll from the top for replacement and installation, which is not conducive to workers to replace and maintain. Workers also have the risk of working at height when replacing the roll from the top. The equipment may be damaged during disassembly.
