Powder spraying room for electrostatic spraying

Abstract

The invention relates to the technical field of powder spraying, and discloses a powder spraying room for electrostatic spraying. The powder spraying room comprises a first room body structure and a second room body structure; the first room body structure is internally divided into a spraying area and a spraying supplementing area; the second room body structure is close to and communicates withthe spraying supplementing area; a pulse recovery device is arranged outside the second room body structure, wherein an inlet of the pulse recovery device communicates with the second room body structure; the pulse recovery device comprises a fan, a pulse filter element, a pulse solenoid valve and a powder recovery barrel; the fan is located on the upper portion of the pulse recovery device; the pulse filter element and the pulse solenoid valve are located in the middle of the pulse recovery device; the pulse filter element communicates with the fan through the pulse solenoid valve; and the powder recovery barrel is located at the bottom of the pulse recovery device and detachably connected with the pulse recovery device, and idler wheels are arranged at the bottom of the powder recovery barrel. The powder spraying room can assist in checking and guaranteeing the workpiece powder spraying quality in real time.

Description

technical field [0001] The invention relates to the technical field of powder spraying, in particular to a powder spraying booth for electrostatic spraying. Background technique [0002] The surface of metal structural parts, cold-rolled steel sheets, galvanized steel sheets, and aluminum sheets will be sprayed with external powder in order to maintain a long-term aesthetic effect and service life, and the most popular one is electrostatic powder spraying. [0003] In order to protect the environment and avoid pollution, electrostatic spraying is usually carried out in the powder spraying room. The powder spraying room is generally equipped with an inlet and outlet and a hanging conveyor chain on the top of the powder spraying room. The workpiece is transported into the powder spraying room through the hanging conveyor chain. Inlet, and through the powder spraying pipes and spray heads fixed in the powder spraying room, the assembly line powder spraying operation is carried ...

AI Technical Summary

Problems solved by technology

[0003] In order to protect the environment and avoid pollution, electrostatic spraying is usually carried out in the powder spraying room. The powder spraying room is generally equipped with an inlet and outlet and a hanging conveyor chain on the top of the powder spraying room. The workpiece is transported into the powder spraying room through the hanging conveyor chain. Inlet, and through the powder spraying pipes and spray heads fixed in the powder spraying room, the assembly line powder spraying operation is carried out until the workpiece is transported out of the material outlet. The excess powder on the surface is not conducive to the quality assurance of the workpiece; the powder room cannot maintain the long-term effective guarantee of the powder spraying quality, and it is necessary to manually clean the powder stuck in the room frequently; in order to ensure the quality of spraying and the recycling of excess powder in the room, In some powder spraying rooms, dust suction or dust blowing devices are installed in the room, and the walls and top surfaces of the powder spraying rooms are effectively vacuumed and cleaned by wind force, but the dust suction device can only be used after the powder spraying work stops. It only guarantees the quality of part of the powder spraying after cleaning, which is not conducive to ensuring the powder spraying quality of the workpiece in real time during the production process.
