Abstract
The invention provides a labyrinth type inlet air decompressing method and a labyrinth type inlet air decompressing device of a shot blasting machine, which relate to material and surface processing equipment. An air intake passage is arranged on the wall of a cleaning chamber and is in the rotary shape of 'S'; internal air and external air of the cleaning chamber are communicated; the outer mouth of the cleaning chamber is higher than the inner mouth of the cleaning chamber; and the cross section of the narrowest place of the air intake passage is 1/8 to 1/10 of the area of a door of the cleaning chamber. In the device, air flow from an air inlet to a dust collector is generated by inletting air from exterior and fine dust which is primarily suspended in the cleaning chamber enters the dust collector, so the dust-removing effect is greatly improved, the cleanness of a workpiece surface is obviously improved, and the leakage of the dust when the door is opened is reduced. At the same time, due to the entrance of the outdoor air, the indoor and outdoor pressure difference is reduced, and the opening pressure when the door is opened is released.
Description
Technical field
The present invention relates to material and surface processing equipment.
Background technology
Current material and surface processing equipment, the cleaning chamber air-proof condition of many types is all relatively good.When workpiece is done surperficial Shot Blasting in cleaning chamber, the formed dust of impelling workpiece in the body of chamber, always some can not fully be sucked discharging by dust pelletizing system.These remaining dust directly affect the cleannes of workpiece because the negative pressure that produces during the ball blast dust-collecting indoor is suspended in the body of chamber.The negative pressure that produces during simultaneously dust suction has been brought pressure when also giving the chamber door of opening cleaning chamber.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can help dedusting, remove shot-blasting machine labyrinth type air intake decompressing method and the device of chamber door opening pressure.
The technical solution of shot-blasting machine labyrinth type air intake decompressing method of the present invention is: the locular wall at cleaning chamber arranges air-intake device, utilize external air inlet, the air-flow of generation from air inlet to dust catcher makes the former fine solid particle that is suspended in the cleaning chamber enter dust catcher with air-flow; Simultaneously, entering of outdoor air reduced in the body of chamber and outdoor pressure reduction, removed the opening pressure of chamber door; In order to guarantee the flow of air intake, air intake passage the sectional area at narrow place be the cleaning chamber chamber shop front long-pending 1/8～1/10, in order to prevent that the ball material from leaking and the outflow of dust, air intake passage is serpentine revolution shape.
The technical solution of labyrinth air inlet depressurizing device of shot blasting machine of the present invention is: labyrinth air inlet depressurizing device of shot blasting machine, it is characterized in that: it is an air intake passage that is embedded on the cleaning chamber locular wall, air intake passage is serpentine revolution shape, it connects the cleaning chamber inner air and outer air, its collar extension is higher than internal orifice, air intake passage the sectional area at narrow place be the cleaning chamber chamber shop front long-pending 1/8～1/10.
Say that further described air intake passage is formed successively side by side by some serpentine slalom courses.
Say that further air intake passage is arranged on the door of cleaning chamber chamber.
Say that further air intake passage is arranged on the bottom of cleaning chamber chamber door.
Say that further described serpentine slalom course is provided with the sidewalk for visually impaired people of one section rising from first curved point of cleaning chamber admission passage.
Say that further described serpentine slalom course is made of three guide plates, a deflecting plate and two baffle plates; Three guide plates be arranged in parallel, with the folded acute angle of cleaning chamber outer wall less than or equal to 40 °; Intermediate guide plate is shorter than the guide plate of both sides; The anti-guide plate direction of deflecting plate is arranged on the rear of intermediate guide plate, between deflecting plate and the intermediate guide plate space is arranged, and deflecting plate and the folded acute angle of cleaning chamber inwall are 35 °～45 °; Between upper guide plate and the deflecting plate, be connected with respectively baffle plate between middle guide plate and the lower guide plate.
Say that further as intermediate guide plate is extended, then intermediate guide plate can intersect with deflecting plate, the length of deflecting plate is to extend more than 2 centimetres than intersection location, guarantees that simultaneously the distance of deflecting plate end-to-end distance lower guide plate is more than or equal to 2 centimetres.
Say that further the distance between intermediate guide plate end and the deflecting plate is more than or equal to 2 centimetres.
Use the present invention, locular wall at cleaning chamber arranges air intake passage, utilize external air inlet, the air-flow of generation from air inlet to dust catcher, make the former fine solid particle that is suspended in the cleaning chamber enter dust catcher with air-flow, increased substantially dust removing effects, the cleannes of surface of the work are obviously improved, and dust leaks when having reduced to open the door.Simultaneously, entering of outdoor air reduced in the body of chamber and outdoor pressure reduction, removed the opening pressure of chamber door.Serpentine revolution design and the inclined design of air intake passage have prevented that effectively the ball material from leaking and the outflow of dust.The length of deflecting plate is to extend more than 2 centimetres than intersection location, have on the one hand and can stop that the ball material ejects from the gap between middle guide plate tail end and the deflecting plate, on the other hand air intake is introduced lower floor's chute, helped to prevent that dust from directly directly overflowing from the gap between middle guide plate tail end and the deflecting plate.Serpentine revolution air intake passage is provided with the sidewalk for visually impaired people of one section rising from first curved point of cleaning chamber admission passage in addition, makes air intake can form herein one than air pressure environment higher in the cleaning chamber, has further suppressed overflowing of dust.The area of serpentine revolution air intake passage air inlet be the cleaning chamber chamber shop front long-pending 1/8～1/10, and the distance between intermediate guide plate tail end and the deflecting plate has guaranteed the flow of the wind of air intake passage more than or equal to 2 centimetres.
