Description

Technical Field

[0001] The utility model relates to the technical field of ore processing, in particular to a sandblasting device for processing the surface layer of an ore. Background Art

[0002] After ore mining and processing, its surface may be attached with dirt, oxide layer or other attachment layers. Most of the attachment layers are difficult to remove by washing. Therefore, sandblasting equipment is currently used to treat the ore surface after mining.

[0003] The existing ore surface sandblasting device includes a dustproof box for preventing dust from spreading, a chain link conveyor belt for conveying ore, and a sandblasting system for sandblasting the ore surface. The chain link conveyor belt has chains and beams, and the beams are arranged at intervals, and gaps are formed between the beams for sand to pass through. When the ore on the chain link conveyor belt passes through the sandblasting system, the sandblasting nozzles around it sandblast the ore surface, and there are gaps between the beams, so that the sandblasting nozzles can flush the bottom of the ore from below.

[0004] The ore and the beam are relatively still, which makes it easy for the contact part between the ore and the beam to form a dead angle for cleaning, resulting in incomplete cleaning of the ore surface.

[0005] Due to the irregular shapes and sizes of ore blocks, it is difficult to solve the problem of cleaning dead corners by turning over or moving the ore. In addition, the initial investment cost is high and it is difficult to implement if the ore is identified and processed one by one. In addition, the daily processing volume required is relatively large. If the position of the ore is adjusted one by one, the processing volume of the ore will be reduced. Utility Model Content

[0006] The purpose of the utility model is to provide a sandblasting device for processing the surface layer of ore in order to solve the above problems.

Both the feed port 101 and the discharge port 103 are equipped with dustproof curtains to reduce the diffusion of dust. A collection plate 102 for collecting sand is provided at the bottom of the dustproof box 1. Two collection plates 102 are provided. The collection plates 102 are tilted to facilitate the collection of sand. In other embodiments, four collection plates 102 or a conical barrel structure can also be used to collect sand.

[0030] In order to further prevent the spread of dust, the dustproof box 1 can be connected to a dust removal device to absorb and filter the dust through negative pressure, thereby reducing the impact of the dust on the surroundings.

[0031] The first chain-link conveyor belt 3 is installed in the dustproof box 1, and the first chain-link conveyor belt 3 is used to convey ore; the first chain-link conveyor belt 3 includes two sprockets 304 arranged in the left-right direction, and the sprockets 304 are rotatably assembled on the side wall of the dustproof box 1, and the motor drives one of the sprockets 304 to drive the first chain-link conveyor belt 3 to run, and a chain 301 is wound between the two sprockets 304, and two chains 301 are arranged in the front-to-back direction, and a number of crossbeams 302 for supporting ore are evenly distributed between the two chains 301, and a number of load-bearing rollers 303 for supporting the chain 301 are also arranged between the two sprockets 304, and the load-bearing rollers 303 supporting the chain 301 can delay the deformation of the chain 301, thereby extending the service life of the first chain-link conveyor belt 3, and the structure of the second chain-link conveyor belt 6 is the same as that of the first chain-link conveyor belt 3.

[0032] The second chain-link conveyor belt 6 , the first chain-link conveyor belt 3 and the second chain-link conveyor belt 6 are installed in the dustproof box 1 along the left-right direction, the first chain-link conveyor belt 3 is located on the side of the dustproof box 1 close to the feed port 101 , and the height of the first chain-link conveyor belt 3 is higher than that of the second chain-link conveyor belt 6 .

[0033] The transition frame 5 is obliquely arranged between the first chain-link conveyor belt 3 and the second chain-link conveyor belt 6, so that the ore on the first chain-link conveyor belt 3 falls onto the second chain-link conveyor belt 6 through the transition frame 5; the transition frame 5 includes a mounting frame 502 and a plurality of transition rollers 501 arranged at intervals on the mounting frame 502, and the transition rollers 501 are rotatably assembled on the mounting frame 502.

[0034] The sandblasting system 4 includes a sand material tank 403 for storing sand material, a medium power system 404, a main sandblasting nozzle 401 and an auxiliary sandblasting nozzle 402 installed in a dustproof box 1, the main sandblasting nozzle 401 is arranged at the first chain-link conveyor belt 3, and since the cleaning dead corner of the ore is located below the ore, the auxiliary sandblasting nozzle 402 is arranged below the transition frame 5, and the medium power system 404 is respectively connected to the sand material tank 403, the main sandblasting nozzle 401 and the auxiliary sandblasting nozzle 402 through pipelines. Among them, the main sandblasting nozzle 401 is provided with 4-6, and the main sandblasting nozzle 401 can cover the entire ore block 2, and the auxiliary sandblasting nozzle 402 is provided with 1-3, and generally 2 are provided. Except for the auxiliary sandblasting nozzle 402, the other structures of the sandblasting system 4 are all existing technologies and have not been modified, and its specific structure will not be repeated here.

[0035] Working principle: After starting, the ore block 2 to be processed is transported to the first chain-link conveyor belt 3 through an external conveying mechanism. When the ore moves to the middle position of the first chain-link conveyor belt 3, each main sandblasting nozzle 401 sandblasts the ore from the top, bottom, front, and back directions of the ore. After the sandblasting is completed, the ore is not cleaned thoroughly at this time due to the problem of cleaning dead corners caused by the crossbeam 302. When the ore falls to the transition frame 5, since the transition frame 5 is tilted and the transition frame 5 has a rotatable transition roller 501, the ore that falls on the transition frame 5 falls due to gravity. During the falling process, the originally blocked cleaning dead corners are exposed, and the auxiliary sandblasting nozzle 402 located below the transition frame 5 performs secondary sandblasting on the bottom of the ore, which solves the problem of incomplete cleaning of the ore surface. After cleaning, the ore is discharged through the second chain-link conveyor belt 6.

[0036] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
