Detailed implementation manners

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-4 shown, a conveying mechanism for the production of bearing steel sand provided by an embodiment of the present utility model includes a frame 1. The inside of the frame 1 is connected with a first roller 2 and a second roller 3 through bearings. A conveyor mesh belt 4 is drivingly connected between the first roller 2 and the second roller 3. One outer wall of the frame 1 is fixed with a motor 11. One end of the output shaft of the motor 11 is key-connected to the first roller 2. The inside of the frame 1 is fixed with a hollow plate 6. The top outer wall of the hollow plate 6 is connected with evenly distributed air outlet nozzles 7. One outer wall of the frame 1 is fixed with an air pump 5. The air outlet of the air pump 5 is connected to the hollow plate 6 through a pipeline. The hollow plate 6 is located at the bottom of the conveyor mesh belt 4.

[0023] Specifically, in this embodiment, it includes a frame 1. Inside the frame 1, a first roller 2 and a second roller 3 are connected by bearings. A conveyor belt 4 is drivingly connected between the first roller 2 and the second roller 3. The conveyor belt 4 has mesh holes, and the mesh holes of the conveyor belt 4 are much smaller than the particle size of bearing steel sand. On one outer wall of the frame 1, a motor 11 is fixed. One end of the output shaft of the motor 11 is key-connected to the first roller 2, and the motor 11 drives the first roller 2 to rotate. Inside the frame 1, a hollow plate 6 is fixed. The inside of the hollow plate 6 is hollow. The top outer wall of the hollow plate 6 is connected with evenly distributed air nozzles 7. When compressed air is introduced into the inside of the hollow plate 6, the compressed air can be ejected upward from the air nozzles 7, thereby achieving the effect of removing dust from the bearing steel sand on the conveyor belt 4. On one outer wall of the frame 1, an air pump 5 is fixed. The air outlet of the air pump 5 is connected to the hollow plate 6 through a pipeline. The air pump 5 is used to introduce compressed air into the inside of the hollow plate 6. The hollow plate 6 is located between the upper layer and the lower layer of the conveyor belt 4, so that the air nozzles 7 on the hollow plate 6 can be relatively close to the conveyed bearing steel sand, and thus the effect of removing dust from the bearing steel sand by the compressed air is better.

[0024] For a conveying mechanism for the production of bearing steel sand provided by the present utility model, by introducing compressed air into the inside of the hollow plate 6 through the air pump 5, after the compressed air is ejected from the air nozzles 7, the compressed air can blow up the dust in the bearing steel sand, thereby achieving the effect of removing dust during the conveying of the bearing steel sand and improving the quality of the produced bearing steel sand.

[0025] In another embodiment provided by the present utility model, a box body 9 is fixed on one side of the frame 1. A centrifugal fan 10 is connected to the top of the box body 9 by bolts. The centrifugal fan 10 is used to extract the air inside the box body 9. A wind collecting hood 8 located above the conveying mesh belt 4 is fixed on one side of the box body 9. The hollow plate 6 is located at the bottom of the wind collecting hood 8, and the wind collecting hood 8 is directly above the hollow plate 6. An air inlet pipe 16 is connected between the wind collecting hood 8 and the box body 9, so that dust can enter the interior of the box body 9 from the wind collecting hood 8. A discharge pipe 18 is welded to the outer wall of one side of the centrifugal fan 10; a support plate 17 is fixed inside the box body 9. The height of the air inlet pipe 16 is lower than that of the support plate 17. Uniformly distributed filter cartridges 20 are arranged at the bottom of the support plate 17. The bottom of the filter cartridge 20 is closed, and the dust is filtered by the filter cartridges 20; a connecting pipe 21 is fixed to the top end of the filter cartridge 20, and the connecting pipe 21 is communicated with the filter cartridge 20. Uniformly distributed connecting rings 19 are welded to the outer wall of the bottom of the support plate 17. The top end of the connecting pipe 21 is threadedly connected to the connecting ring 19. The filter cartridge 20 is communicated with the space of the box body 9 above the support plate 17 through the connecting pipe 21. Thus, the air enters the space of the box body 9 above the support plate 17 after being filtered by the filter cartridges 20. At the same time, the filter cartridge 20 can be conveniently disassembled from the support plate 17, making the filter cartridge 20 easy to replace. An inspection opening 22 is formed in the outer wall of one side of the box body 9, and a sealing plate 23 connected to the box body 9 by bolts is covered at the inspection opening 22. When the sealing plate 23 is disassembled in the shutdown state, the disassembled filter cartridge 20 can be taken out from the inspection opening 22. A drawer 24 is movably inserted into the outer wall of one side of the box body 9. The drawer 24 is located at the bottom of the filter cartridge 20. The drawer 24 is used to collect the dust falling on the outer wall of the filter cartridge 20. At the same time, the drawer 24 can be taken out, making it convenient to clean the dust inside the drawer 24.

[0026] In another embodiment provided by the present utility model, arc surfaces 12 are arranged in the middle parts of the first roller 2 and the second roller 3. Due to the arc surfaces 12, the first roller 2 and the second roller 3 are in a structure with a thinner diameter in the middle and thicker diameters at both ends. Due to the arc surface 12 structure formed by the first roller 2 and the second roller 3, the middle part of the conveying mesh belt 4 can form a concave shape. Thus, when the conveying mesh belt 4 conveys bearing steel sand, it is not easy to occur the phenomenon of spilling. Limiting grooves 13 are arranged on the outer walls of both ends of the first roller 2 and the second roller 3. A guiding strip 14 is fixed to the outer wall of one side of the conveying mesh belt 4 close to the first roller 2. The guiding strip 14 is made of a soft material. The guiding strip 14 is located inside the limiting groove 13. A steel wire rope 15 is fixed inside the guiding strip 14. By means of the steel wire rope 15, the guiding strip 14 of the conveying mesh belt 4 can be always located inside the limiting groove 13, thereby preventing the conveying mesh belt 4 from running off track.

[0027] Working principle: During use, the motor 11 drives the first roller 2 to rotate, causing the first roller 2 to drive the conveyor belt 4 and the second roller 3 to rotate. The bearing steel sand to be conveyed is sparsely spread on the conveyor belt 4, and the conveyor belt 4 conveys the bearing steel sand. Compressed air is introduced into the interior of the hollow plate 6 through the air pump 5, and the compressed air flows out from the air outlet nozzle 7 and blows towards the bearing steel sand passing above, causing the dust in the bearing steel sand to float. When the centrifugal fan 10 operates, the dust enters the interior of the box body 9 through the negative pressure from the air collecting hood 8, and the filter cartridge 20 inside the box body 9 filters the dust. Then, the clean air passes through the filter cartridge 20 and enters the top of the support plate 17, and then the air flows out from the air outlet pipe 18 after passing through the centrifugal fan 10.

[0028] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
