Problems solved by technology

[0006] 1) After filtering, the paint mist filter bag often needs to be replaced every 8 hours. The filter material is replaced too frequently, and it is prone to serious blockage, which increases the wind resistance in the spray booth and fills the room with paint mist
[0007] 2) Since the structural design is integrated or fixed, it is troublesome to manufacture, install, and replace, and it is extremely inconvenient to clean after replacement
[0008] 3) The more common connection method between the 3D paint mist filter bag and the main frame is the direct connection with bolts. Therefore, when disassembling, it is necessary to unscrew several bolts to remove the replaced filter bag, and then the newly replaced filter bag needs to be removed. After the bag is installed, the operation is cumbersome, time-consuming and labor-intensive, and the parts are scattered and easy to lose
[0009] 4) In addition, the structure of the 3D paint mist filter bag is not stable enough in the air duct with a large ventilation volume, and it is easy to shake or swing under the blowing of the strong wind, which affects the smoothness of the air flow in the air duct

Abstract

The invention discloses an easy-to-install paint mist filter bag and a manufacturing method. The easy-to-install paint mist filter bag includes a filter bag body, which comprises a fixed frame, an internal connection frame and an external connection frame; the fixed frame is disposed at the openings of single filter bags in press fit, connection lugs are integrally arranged on both sides of the fixed frame symmetrically; the internal connection frame is embedded to the fixed frame, two side frames of the internal connection frame dent inward and are provided with connecting grooves, a lug connection frame for cooperative connection with the connection lugs is integrally disposed at the bottom of the internal connection frame close to two ends; two ends of the external connection frame stretch downward, and the external connection frame is internally equipped with elastic connecting pieces in cooperative connection with the connecting grooves. The easy-to-install paint mist filter bag provided by the invention has the characteristics of simple and reasonable structure, convenient disassembly, rapid replacement and stable structure, and a filter surface adopts equally spaced diamond-shaped through-holes, so that the filtering effect and ventilation effect of the filter bag are better than those of the existing plane filter layer, and the service life of the structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an easy-to-install paint mist filter bag and a manufacturing method. Background technique [0002] With the upgrading and improvement of national environmental protection laws and regulations, the requirements for the treatment of volatile organic compounds (VOCs) are clear, and the real-time monitoring of environmental protection departments has moved from theory to reality. The original extensive paint mist treatment methods in some painting workshops cannot meet the requirements of regulations. Various VOCs waste gas treatment equipment is in use Applications in the painting industry have encountered processing difficulties. In recent years, most painting workshops have used paint mist felts and environmentally friendly paper filters to filter paint mist, so that the filtered gas can be discharged up to the standard. [0003] Paint mist felt is a filter material made of fluff...
