Spraying chamber

Abstract

The spray booth has no trouble for the paint attached to the ceiling of the spray booth to fall onto the sprayed article contaminatively and has changeable front opening size for minimized airflow rate for spraying. The spray booth is provided with one rotary filter net, one movable filter net wall near the ceiling for removing the paint attached to the filter net, and one removing device outside the spray booth to operate regularly for removing the attached paint. In addition, the spray booth has one front movable reduced opening, and the opening may be moved and changed in area based on the size and the shape of the sprayed article so as to minimize the airflow rate for spraying.

Description

technical field [0001] The present invention relates to a spray booth for collecting and treating paint mist splashed by spraying during painting. Background technique [0002] The spray booth (hereinafter referred to as the coating booth) is used to attract and capture the paint mist that has not adhered to the object to be coated with the spray, so as to prevent it from adhering to the object to be coated again, and is used to reduce An indispensable device for the discharge of harmful substances that adversely affect the surrounding environment including paint mist. The paint particles sprayed in the painting room that are not attached to the object to be painted are attracted by the airflow toward the exhaust gas treatment device, but it cannot be avoided due to the direction of the spray, the turbulent flow of the airflow, or the position of the wall surface that the airflow contacts, etc. attached to the interior wall. [0003] The attached paint is used for a long t...

Problems solved by technology

Therefore, it is hoped that the painting room is wide enough, and the distance between the object to be painted and the wall is long, so that the paint mist can be attracted by the exhaust flow before it reaches the wall. However, this will increase the size of the painting room and increase the burden on equipment.

[0015] In the case where the painting room is narrow and the distance between the wall surface and the object to be painted is small, the paint gradually adhering to the wall surface accumulates and becomes dirty, causing adverse effects on the surroundings or the object to be painted

In particular, the fall of paint adhering to the ceiling surface as described above can cause poor coating of the object to be coated, so regular cleaning is unavoidable, resulting in a decrease in productivity or a burden on the operator.
