Embodiment example
[0041] Take the famous construction machinery water-based paint spray booth as an example.
[0042] Working conditions: 288 days / year, 20 hours / day.
[0043] Workpiece parameters: 1100 sets / month about 2400 sets / month
[0044] The largest workpiece size of a single workpiece: 1485*1460*280mm
[0045] Taking the new system put into use as an example, the usage method is as follows:
[0046] 1. In the dry carton filter system 1, the carton filter 11 has a specification of 820x665x840 and a quantity of 28. The air volume of the spray booth is 60000m3 / h, the replacement cycle is not less than 30 days, and the paint mist purification rate is greater than 98%;
[0047] 2. When performing maintenance and replacement, follow the above operation steps. The time for each group is about 8 minutes, and all the above replacement work can be completed in 2 hours.

The invention provides a water-based paint spray booth dry-type filtering device and a maintenance and replacement method thereof. The water-based paint spray booth dry- type filtering device and themaintenance and replacement method thereof are safe, low in cost and large in paint containing capacity, and particularly a carton filter is convenient to replace. A support is fixedly installed in apit. A first fluency strip is mounted on the support; the carton filter is arranged on the support and is placed above a first fluency strip; a second fluency strip is arranged in a placement area; alifting frame is vertically mounted in the pit; an electric hoist is mounted on the lifting frame; a framework is connected with the electric hoist; and a pulley is installed on the framework, and theframework is slidably connected with the lifting frame through the pulley in a lifting mode. When the carton filter is maintained and replaced, a carton replacing trolley is pushed to the front of the support, the saturated carton filter is pushed out of the support through the first fluency strip, and then the saturated carton filter is pushed into the carton replacing trolley through the secondfluency strip. The carton replacing trolley with the saturated carton filter is pushed into the framework, the electric hoist acts to enable a hanging basket to ascend, the carton replacing trolley is conveyed to the ground, and a new carton filter is returned through an original path.
Description
technical field [0001] The invention relates to a water-based paint spray booth dry filter device and a maintenance and replacement method thereof. Background technique [0002] With the increasingly stringent environmental protection requirements, water-based paints have gradually increased their market share due to their low VOC content and good performance. However, due to the small working window of the water-based paint spray booth, the need for temperature control and humidity control, and the need for stainless steel in the room, the requirements for the use of water-based paint have become relatively harsh. [0003] As far as the paint mist treatment structure at the bottom of the water-based paint spray booth is concerned: if a traditional wet spray booth is used, the sewage treatment, waste residue treatment and maintenance of the circulating pool are the key points and difficulties in the work; if the traditional dry paint mist filter cotton is used, the paint cap...
