Spraying chamber

Abstract

The spraying room of the present invention can solve the problem that the paint attached to the ceiling surface of the painting room falls onto the object to be painted during spraying and painting, causing contamination, and at the same time, the size of the opening in front of the painting room can be changed Paint with minimal exhaust. A movable filter screen wall is formed on a part of the ceiling surface of the painting room, and the paint attached to the filter screen is removed. The filter screen can be rotated, so that the removal device installed outside the painting room works regularly to remove the attached paint and process it together with the paint mist. In addition, a reduced opening is formed in the front of the painting booth, and the opening is movable. The opening is moved in accordance with the size and shape of the object to be coated in the painting chamber, and the opening area is changed, so that the painting can be performed with the minimum exhaust volume.

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...

AI Technical Summary

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.
