Vertical circular spraying chamber applied to powder spray-coating line

Abstract

The invention discloses a vertical circular spraying chamber applied to a powder spray-coating line. The vertical circular spraying chamber comprises a vertical spraying chamber main body, wherein the spraying chamber main body is formed mainly by defining a front side plate and a rear side plate which are positioned on the front and rear sides respectively; the middle parts of the front and rear side plates are outwards arched to form circular arcs; a feed opening and a discharge opening are formed in the left and right sides of the spraying chamber main body respectively, and are used for the feeding and discharging of a workpiece; an air draft opening connected with an external air draft pipeline is formed in the outwards-arched position of the middle part of the rear side plate. According to the vertical circular spraying chamber, the front and rear side plates define a relatively enclosed space, and the middle parts of the front and rear side plates are outwards arched to form the circular arcs, so that the space in the spraying chamber is enough for the powder spray-coating of the workpiece, the feed opening and the discharge opening in the left and right sides of the spraying chamber are small, the opening area of the spraying chamber is reduced, and the requirements of the spraying chamber on air draft can be met by a relatively low-power draft fan.

Description

Technical field [0001] The invention relates to the field of powder spraying, in particular to a spray booth for powder spraying lines. Background technique [0002] At present, there are two main types of vertical powder spraying line spray booths that exist and are used in the market, namely V-shaped vertical powder spraying booth and U-shaped vertical powder spraying booth. figure 1 , The structure of the V-shaped vertical powder spray booth is relatively simple. The transparent plastic film is used to make two identical splints-1'. The two splints-1'are enclosed to form a V-shaped opening slot, and one is provided at the rear of the opening slot. Suction slot, the suction slot is connected with a suction pipe 10', the open end of the opening slot is provided with a suspension chain 2'extending along the opening shape, and the suspension chain 2'transports the workpieces to the opening end of the opening slot in turn Do powder spraying, and then send it away. When powder spray...

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.
