Description
Technical Field
[0001] The invention relates to the technical field of dust removal devices, in particular to an abrasive dust removal device for a shot blasting machine used in the production of steel structural parts. Background Art
[0002] Shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously remove sand, core and clean castings. In some areas, it is also verbally called a sandblasting machine or a sandblasting machine. When the shot blasting machine processes steel structural parts, the outer surface of the steel structural parts is polished by abrasives. In this process, more dust and debris will be generated. Part of the dust can be directly absorbed by the dust collection equipment of the polishing machine, but some dust and debris mixed in the abrasive are difficult to clean directly.
[0003] Because the abrasives in the shot blasting machine are generally small in size and large in number, they are easily piled up to hide dust and debris. The prior art uses screening to separate the abrasives from debris and dust. However, in this process, due to the crowding of the abrasives, it is difficult to quickly complete the separation by simply relying on the screen plate, and the dust adhering to the surface of the abrasive is also difficult to remove by separation through the screen plate. Summary of the invention

[0014] Furthermore, a drain pipe is installed at the bottom of the dust removal box.
[0015] Beneficial effects of the present invention:
[0016] 1. The present invention drives the circular plate to slide back and forth inside the dust removal box through the first motor. During this process, the sponge layer on the edge of the circular plate can be compressed and rebounded cooperatively, so as to keep the circular plate sealed with the inner wall of the dust removal box while avoiding the obstruction of the movement of the circular plate when rotating left and right. In addition, the shaking of the circular plate can evenly distribute the abrasive and accelerate the separation of dust and debris in the abrasive.
[0017] 2. After the abrasive is concentrated on the center plate through the wrapping net, the second electric push rod drives the mounting plate to descend, and the cleaning roller is inserted into the cylinder of the wrapping net. At this time, the plug block of the vertical rod is inserted into the slot of the center plate. When the second motor rotates, the first gear rotates and engages with the second gear. The first gear drives the shaft rod and the center plate to rotate along the circular plate. The second gear drives the cleaning roller to rotate and scrub the abrasive concentrated in the wrapping net. Then, the clean water in the outer water tank is sprayed on the inside of the wrapping net through the spray rack and the nozzle to perform secondary flushing on the surface of the abrasive. The sewage generated by the flushing directly flows into the lower layer through the through holes of the circular plate and the center plate. The top of the circular plate and the lower layer of the dust removal box can be simply cleaned and then flow out from the drain pipe.
[0018] 3. Before receiving the abrasive, the screw and the threaded end of the telescopic plate cooperate with each other to move the limit frame to the storage grooves on both sides of the dust removal box. At this time, the wrapping net is attached to the inner wall of the dust removal box, and will not interfere with the uniform spreading of the abrasive on the circular plate and the primary separation of dust and debris. After the primary dust removal is completed, the screw rotates, and the telescopic plate drives the limit frame to slide along the surface of the wrapping net and gradually approaches the center plate. In this process, the area wrapped by the wrapping net gradually shrinks until the plug-in plate of the limit frame is inserted into the plug-in frame. At this time, the wrapping net just wraps the outer area of the center plate to form a cylinder, and in this process, when the wrapping net is gathered toward the middle, the spread abrasive will be concentrated toward the center plate and gradually piled up together, which is convenient for subsequent secondary cleaning and dust removal. The function of the telescopic plate is that when the cleaning component descends and is inserted into the cylinder composed of the wrapping net, the connection between the limit frame and the screw can be maintained through its elasticity.
[0019] 4. Compared with the prior art, the present invention feeds the abrasive onto a circular plate, and the abrasive is spread out by shaking the circular plate to avoid accumulation. The shaking process can accelerate the separation of debris and dust hidden in the abrasive from the abrasive, and then the abrasive is piled up by the enclosure component, and the surface of the abrasive is brushed by the cleaning component. In the piled state, the brushing efficiency can be improved, dust can be further removed, and it is convenient to send out after dust removal. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the abrasive can be evenly distributed through the shaking of the circular plate 21, and the separation of dust and debris in the abrasive can be accelerated. After the primary dust removal is completed, the screw 45 rotates The telescopic plate 34 drives the limit frame 32 to slide along the surface of the wrapping net 31 and gradually approaches the center plate 22.
