Dry type spray chamber

Abstract

The invention discloses a dry type spray chamber. The chamber comprises a spray chamber body, a lower filtering part, a throat structure, an exhaust pipeline and a centrifugal fan, wherein an air inlet is formed in the upper end of the spray chamber body; the lower filtering part is arranged at the bottom inside the spray chamber body, a filtering inlet is formed in the lower part of the lower filtering part, and a filtering outlet is formed in the upper part of the lower filtering part; the throat structure is arranged at the filtering inlet, one end of the throat structure is arranged towards the interior of the lower filtering part, and the other end of the throat structure is arranged obliquely downwards; one end of the exhaust pipeline is connected to the filtering outlet; and the input end of the centrifugal fan is connected to the other end of the exhaust channel. Through the application of the chamber, a structure of the spray chamber is greatly simplified, the consumption and pollution caused in the filtering process are further reduced while filtered gas is ensured to meet the standard, and the use and manufacturing cost of the spray chamber is favorably reduced.

Description

technical field [0001] The invention relates to the technical field of spray booths, in particular to a dry spray booth. Background technique [0002] In the process of automobile production and the preparation of various large parts, it is often necessary to spray paint in the spray booth. At present, the most common spray booth is to use spraying and water curtain device to spray the paint produced in the process of spraying. Therefore, the content of paint molecules in the discharged gas is greatly reduced. However, this filtering method often requires the cooperation of water pumps, water tanks, water pipes, slag scrapers and other equipment to complete, so that the entire spray booth The production cost has been greatly increased, and it has also caused certain water resource pollution and unnecessary energy consumption. Contents of the invention [0003] In view of this, in order to solve the above problems, the object of the present invention is to provide a kind o...
