Description

Technical Field

[0001] This utility model belongs to the field of ore pretreatment technology, and in particular relates to a crusher for ore pretreatment. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain usable properties. It can be divided into metallic minerals and non-metallic minerals.

[0003] Because the ore particles vary in size when they are first mined, and some are quite large, they are not easy to sort and process. Therefore, after mining is completed, the ore needs to be pre-crushed to make the size of the ore more uniform, so as to facilitate subsequent sorting. However, the crushing process generates a lot of dust, which leads to a high particle concentration around the crusher. This not only pollutes the surrounding atmosphere, but also generates sparks when the minerals are crushed, which may lead to the risk of dust explosion.

[0004] Therefore, how to provide a crusher for ore pretreatment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The diagram shown is a structural schematic of a crusher for ore pretreatment provided in one embodiment of the present invention, comprising:

[0032] The crusher frame 1 has a feeding port 8 at its upper end;

[0033] The rotating discharge plate 2 is slidably disposed in the middle of the crusher frame 1;

[0034] Crushing cone 3 is fixedly installed on the top of rotary discharge plate 2;

[0035] Motor 4 is located at the lower end of the crusher frame 1 and is fixedly connected to the bottom of the crushing cone 3;

[0036] The dust removal structure is installed on the surface of the crusher frame 1 to extract the dust in the feed port 8 and cool the motor 4.

[0037] The dust removal structure includes a suction ring pipe 5, a fan 10, and a cooling unit. The suction ring pipe 5 is located in the middle of the upper end of the inlet 8, and has suction holes 6 arranged in a circular array on its inner side. A main suction pipe 7 is fixedly installed at the bottom right side of the suction ring pipe 5. A dust filter box 9 is fixedly installed at the bottom of the main suction pipe 7. A dust filter unit is installed inside the dust filter box 9 to filter dust. The fan 10 is located at the bottom of the rear end of the dust filter box 9, and the cooling unit is located at the bottom of the fan 10 to blow air onto the motor 4.

[0038] In this embodiment of the utility model, when in use, the fan 10 is started, which in turn creates a negative pressure in the rear end of the dust filter box 9, thereby creating a negative pressure in the main suction pipe 7 and the suction ring pipe 5. This allows the suction holes 6 on the inner side of the suction ring pipe 5 to extract the dust generated by the crushing, so that the dust enters the rear end of the dust filter box 9 and is then filtered by the dust filter unit. Clean air is then discharged through the bottom of the fan 10, and the motor 4 is cooled by the cooling unit.

[0039] By setting a dust removal structure on the crusher frame 1, the dust generated by crushing at the upper end of the crusher frame 1 can be extracted to reduce the dust concentration near the crusher frame 1. The extracted dust can also be filtered, and then the motor 4 in the lower end of the crusher frame 1 can be cooled by blowing air, thereby extending the service life of the motor 4.

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment of this utility model, a transmission structure is provided between the rotary discharge disc 2 and the dust filter unit. The transmission structure includes a transmission tooth groove 14, a bevel gear transmission rod 15, a transmission belt 17, and a transmission roller 22. The transmission tooth groove 14 is located at the lower end of the outer side of the rotary discharge disc 2. The transmission roller 22 is located at the upper end of the inner side of the dust filter box 9 and is connected to the dust filter unit. The bevel gear transmission rod 15 is movably located on the right side of the middle part of the crusher frame 1, and its left end is connected to the transmission tooth groove 14. The transmission belt 17 is sleeved on the surface of the right end of the bevel gear transmission rod 15 and the left end of the transmission roller 22, so that the rotary discharge disc 2 and the dust filter unit work synchronously.

[0041] In this embodiment of the utility model, when the rotating discharge disc 2 rotates, the transmission tooth groove 14 at the lower outer end of the rotating discharge disc 2 drives the inclined bevel tooth transmission rod 15 on the right side of the crusher frame 1 to rotate synchronously, and then drives the transmission roller 22 on the inner side of the upper end of the dust filter box 9 to rotate synchronously through the transmission belt 17 on its rear end surface, thereby driving the dust filter unit in the dust filter box 9 to work synchronously.

[0042] By setting a transmission structure between the lower end of the outer side of the rotating discharge disc 2 in the middle of the crusher frame 1 and the dust filter unit of the dust removal structure, the dust filter unit will work synchronously when the rotating discharge disc 2 is working, so that the dust filter unit can work repeatedly, which facilitates the cleaning of dust on its surface and maintains the dust filtering effect of the dust filter unit.

[0043] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, in a preferred embodiment of the present invention, the dust filtration unit includes a filter belt 20 and rollers 21. The rollers 21 are arrayed at the upper and lower ends of the inner cavity of the dust filtration box 9. The filter belt 20 is sleeved on the surface of the upper and lower rollers 21. The upper roller 21 is connected to the transmission roller 22. A scraper 23 is fixedly installed at the bottom of the front end of the inner cavity of the dust filtration box 9. The inner side of the scraper 23 is in movable contact with the bottom of the filter belt 20. A dust collection box 16 is provided at the bottom of the front end of the dust filtration box 9.

[0044] In this embodiment of the utility model, when the transmission roller 22 on the inner side of the upper end of the dust filter box 9 rotates, it will drive the roller 21 on the upper side of the rear end of the dust filter box 9 to rotate synchronously, thereby causing the filter belt 20 to move back and forth in the dust filter box 9. When the filter belt 20 carrying dust moves to the lower end of the front side of the dust filter box 9, it will contact the scraper 23 preset at the bottom of the front side of the dust filter box 9, thereby scraping off the dust on the surface of the filter belt 20 and then dropping it into the dust collection box 16 for centralized storage.

[0045] By setting up a dust filter unit, dust in the air can be filtered out. The dust filtered off the surface of the filter belt 20 is then removed and falls into the dust collection box 16, thus maintaining the filtering effect of the filter belt 20.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the cooling unit includes an air outlet pipe 11 and a spiral pipe 12. The air outlet pipe 11 is fixedly installed at the air outlet at the bottom of the fan 10. The spiral pipe 12 is disposed inside the lower end of the air outlet pipe 11. The bottom of the air outlet pipe 11 passes through the side of the crusher frame 1 and is fixedly connected to the top of the spiral pipe 12. An air outlet groove 13 is provided on the inner side of the spiral pipe 12.

[0047] In this embodiment of the present invention, clean air enters the air outlet 11 through the air outlet at the bottom of the fan 10, and is then discharged into the spiral tube 12, and subsequently blown out from the air outlet groove 13 inside the spiral tube 12.

[0048] By setting up a cooling unit and aligning the direction of the air outlet slot 13 with the position of the motor 4, the air inside the lower end of the crusher frame 1 where the motor 4 is located is disturbed and then blown out from the lower end of the crusher frame 1, thereby allowing the heat from the operation of the motor 4 to be discharged along with the air, thus achieving the cooling effect on the motor 4.

[0049] like Figure 4 and Figure 5As shown, in a preferred embodiment of the present invention, a partition 18 is provided in the middle of the dust filter box 9, and there is a gap between the upper partition 18 and the top of the filter belt 20. An isolation curtain 19 is hinged to the front side of the upper partition 18.

[0050] In this embodiment of the utility model, when in use, a partition 18 is provided in the middle of the dust filter box 9, and a gap is made between the upper partition 18 and the top of the filter belt 20, so that dust can easily enter and exit the front and rear ends of the dust filter box 9 with the filter belt 20. Furthermore, an isolation curtain 19 is hinged to the front side of the upper partition 18, thereby reducing the degree of connection between the front and rear ends of the dust filter box 9, thus facilitating the generation of negative pressure.

[0051] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment of this utility model, the width of the filter belt 20 is equal to the width of the inner cavity of the dust filter box 9, and the upper and lower rollers 21 are staggered.

[0052] In this embodiment of the utility model, when in use, by making the width of the filter belt 20 equal to the width of the inner cavity of the dust filter box 9, it is convenient to filter the dust entering the inner cavity of the dust filter box 9, and the upper and lower rollers 21 are misaligned, so that the filter belt 20 is tilted, thereby facilitating the subsequent discharge of dust.

[0053] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, an elastic filter screen is provided on the surface of the suction hole 6, and the inner side of the suction hole 6 is all facing upward.

[0054] In this embodiment of the invention, when in use, an elastic filter screen is provided on the surface of the suction hole 6 to prevent ore from entering the suction hole 6 and causing blockage. In addition, the inner side of the suction hole 6 is set upward to reduce the dispersion of crushed and pulverized material.

[0055] The present invention provides a crusher for ore pretreatment in the above embodiments. When in use, the ore is fed into the crusher frame 1 through the feeding port 8, and the motor 4 at the lower end of the crusher frame 1 is started at the same time, so that the crushing cone 3 rotates to crush the ore that enters the crusher frame 1, so that the ore particles of the appropriate size fall onto the rotating discharge plate 2.

[0056] Since the rotating discharge plate 2 is located at the bottom of the crushing cone 3, the rotating discharge plate 2 rotates synchronously with the rotation of the crushing cone 3, and is then discharged through the discharge port on one side of the crusher frame 1.

[0057] During the crushing process, the blower 10 is started, which creates a negative pressure in the rear end of the dust filter box 9. This negative pressure then forms in the main suction pipe 7 and the suction ring pipe 5, allowing the suction holes 6 on the inner side of the suction ring pipe 5 to extract the dust generated during crushing. The dust then enters the rear end of the dust filter box 9 and comes into contact with the pre-installed filter belt 20, thereby separating the air from the dust.

[0058] Clean air then enters the air outlet 11 through the air outlet at the bottom of the blower 10, and is then discharged into the spiral tube 12. It is then blown out from the air outlet slot 13 inside the spiral tube 12. Since the direction of the air outlet slot 13 corresponds to the position of the motor 4, the air in the lower end of the crusher frame 1 where the motor 4 is located is disturbed and then blown out from the lower end of the crusher frame 1. This allows the heat from the operation of the motor 4 to be discharged with the air, thereby cooling the motor 4.

[0059] At the same time, when the rotating discharge disc 2 rotates, the transmission tooth groove 14 at the lower outer end of the rotating discharge disc 2 drives the inclined bevel tooth transmission rod 15 on the right side of the crusher frame 1 to rotate synchronously. Then, the transmission belt 17 on its rear end surface drives the transmission roller 22 on the inner side of the upper end of the dust filter box 9 to rotate synchronously, thereby driving the roller 21 on the upper rear end of the dust filter box 9 to rotate synchronously, thus causing the filter belt 20 to move back and forth in the dust filter box 9.

[0060] When the filter belt 20 carrying dust moves to the lower end, it will push open the isolation curtain 19, which will facilitate the dust to move to the lower end of the front side of the dust collection box 9, and then contact the scraper 23 preset at the bottom of the front side of the dust collection box 9, so that the dust on the surface of the filter belt 20 is scraped off and then falls into the dust collection box 16 for centralized storage.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
