Movable paint spray booth

Abstract

The invention discloses a movable paint spray booth which reduces the emission of waste gas, greatly reduces energy consumption and performs paint spray operation on large-scale equipment. The movablepaint spray booth comprises four hollow vertical columns and an upper frame arranged on the four vertical columns, wherein a top plate is detachably arranged at the upper part of the upper frame; anair supply component or a plurality of air inlets are arranged on the top plate; idler wheels are arranged at the bottoms of the vertical columns; two hollow air sucking collecting pipes are oppositely arranged at the lower parts of the four hollow vertical columns; a side blocking screen, the lower edge of which at least covers the air sucking collecting pipe, is arranged on the upper frame; a plurality of air sucking notches are formed in the inner side of the air sucking collecting pipe along a length direction; the width of each air sucking notch greatly increases from the end parts of thetwo ends of the air sucking collecting pipe to the center of the air sucking collecting pipe; a feeding door which closes the side end of the paint spray booth and can be completely opened is arranged between the two adjacent vertical columns without the air sucking collecting pipes; and air-out nozzles which are connected to an exhaust fan by pipelines are arranged at the middles of the outer sides of the vertical columns.

Description

technical field [0001] The invention relates to a mobile paint spray booth. Background technique [0002] Most of the common spray booths in the workshop are fixed. Because the spray booth needs ventilation equipment to ventilate the airtight room, suck away the floating paint droplets, reduce the harm of the spraying operation to the staff, and make the environment in the spray booth Meet environmental protection requirements. In fixed spray booths, ventilation equipment is often installed at one end of the top, and the power of the fan is determined by the concentration of paint droplets in the spray booth. The ventilation volume of the fan needs to meet the environmental protection standard under. There are several problems in the use of the spray booth with this structure: 1. It takes up a lot of space, and the larger equipment to be painted can only be sent in by a forklift. In order to cooperate with the working space of the forklift, the volume of the spray booth in...

AI Technical Summary

Problems solved by technology

There are several problems in the use of the spray booth with this structure: 1. It takes up a lot of space, and the larger equipment to be painted can only be sent in by a forklift. In order to cooperate with the working space of the forklift, the volume of the spray booth increases. 2. High energy consumption and difficult exhaust gas treatment, because the specific gravity of paint droplets is much larger than that of air, this kind of ventilation method of spray booth can suck the air from the remote end into the ventilation equipment, which needs to be equipped with a very high-power motor for the ventilation equipment. Complete the air exchange in the spray booth within a unit time

This further leads to a large amount of exhaust gas, which greatly increases the difficulty and cost of subsequent exhaust gas treatment.

[0003] At present, there is also a mobile spray booth, which slides along the track as a whole. After the equipment to be painted is put, the spray booth can be moved to the equipment to be sprayed, and the equipment is covered in the spray booth to carry out the painting operation. The movable range of the room is limited, and there are still problems of high energy consumption and difficulty in waste gas treatment
