A vertical circular spray booth applied to a powder spraying line

Abstract

A vertical circular spray booth for a powder spraying line, the spray booth comprising a vertical spray booth body (1); the spray booth body (1) is mainly enclosed by a front side plate (11) and a back side plate (12) respectively located at the front side and the back side; the middle parts of the front and back side plates (11, 12) arch outward to form arcs; a feeding port (13) and a discharging port (14) for feeding and discharging work pieces are respectively disposed at the left side and right side of the spray booth body (1); an air exhaust port (120) connected to an external air exhaust channel is provided at the position where the middle part of the back side plate (12) arches; the vertical circular spray booth employs the front side plate (11) and the back side plate (12) to form a relatively enclosed space, and the middle parts of the front side plate (11) and the back side plate (12) arch outward to form arcs, therefore, the spray booth has sufficient interior space to conduct powder spraying on the work pieces, so the feeding port (13) and the discharging port (14) at the left side and right side of the spray booth can be made smaller, reducing the area of openings of the spray booth, and satisfying the air exhaust requirement of the spray booth by employing a relatively low-power exhaust fan.

Description

technical field [0001] The invention relates to the field of powder coating, in particular to a spray booth for a powder coating line. Background technique [0002] At present, there are mainly two types of vertical powder spraying booths that exist and are used in the market, namely V-shaped vertical powder spraying booths and U-shaped vertical powder spraying booths. figure 1 , The V-shaped vertical powder spray booth has a relatively simple structure. Two identical splints-1' are made of transparent plastic film, and the two splints-1' are enclosed to form a V-shaped opening groove. The ventilation slot, the ventilation slot is connected with a suction pipe 10', and the opening end of the slot is provided with a suspension chain 2' extending along its opening shape, and the suspension chain 2' transports the workpiece to the opening end of the slot in turn Carry out powder coating, and then send it away. When powder coating the workpiece, there will be a lot of dust in t...

Problems solved by technology

[0003] refer to figure 2 , U-shaped vertical powder spray booth, also use transparent plastic film to make three baffles 2 1'', three baffles 2 1'' enclose to form a U-shaped opening groove, two adjacent baffles 2 1 There is an air draft slit between the '', the air exhaust pipe 2 10'' is connected to the air draft slit, and a suspension chain 2'' extending along the opening shape of the U-shaped opening groove is provided at the opening end of the U-shaped opening groove. The chain 2'' transports the workpieces to the opening end of the U-shaped open slot in turn for powder coating, and then sends them away. When powder coating the workpieces, a lot of dust will be produced in the air, so it is necessary to start the exhaust fan and pass The air duct two 10'' takes away the dust-containing air and separates and filters it. Since the opening area of ​​the U-shaped vertical powder spray booth is relatively large, it is still necessary to use a relatively large-power exhaust fan to extract the dust-containing air. To avoid dust diffusion, the energy consumption is relatively large. In addition, when spraying powders of different colors, the U-shaped vertical powder spray booth needs to replace the plastic film that makes the second 1'' of the baffle. Although the mechanical belt rotation device is used to replace the plastic film, The replacement speed is slightly faster, but there are many wearing parts, which increases the production cost

[0004] Therefore, the above two spray booths still cannot meet the production needs of the enterprise well.
