Description

Technical Field

[0001] This utility model relates to the field of silica sand processing technology, and in particular to a grinding device for silica sand production. Background Technology

[0002] Silica sand is a natural mineral material with silica as its main component. Its silica content is usually above 90%, and the purity of high-quality silica sand can even reach above 99.5%. It is widely distributed in nature and is one of the most abundant minerals in the Earth's crust.

[0003] During the processing of silica sand, tailings are generated, which are mainly composed of waste or by-products. Tailings often contain a large amount of ultrafine powder. Although these particles are difficult to recover in traditional processes due to their fineness, they actually contain a high proportion of silica or other useful components. Furthermore, the ultrafine powder in the tailings can be directly used as raw material to replace some of the high-purity silica sand or other expensive materials, thereby reducing production costs.

[0004] However, in the aforementioned existing technologies, the content of ultrafine powder in tailings is currently not high, which makes it impossible to achieve efficient utilization of resources and reduce production costs effectively. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding device for silica sand production, which solves the problem that the content of ultrafine powder in the tailings is not high in the existing technology, making it impossible to achieve efficient resource utilization and reduce production costs.

[0006] To achieve the above objectives, this utility model provides a grinding device for silica sand production, including a housing, a fine grinding mechanism, and a feeding and discharging mechanism; The fine grinding mechanism includes a conical grinding block, a conical grinding shell, a gear ring, a gear, multiple support rods, a first motor, and a support plate. The inner bottom wall of the housing has an annular groove. The conical grinding block is fixedly connected to the inner top wall of the housing. The conical grinding shell is disposed inside the housing and located at the lower end of the conical grinding block. The gear ring is fixedly sleeved on the outside of the conical grinding shell. The gear is adapted to the gear ring. The support plate is fixedly connected to the inner wall of the housing. The first motor is disposed at the upper end of the support plate. The output end of the first motor is fixedly connected to the gear. One end of each of the multiple support rods is fixedly connected to the lower end of the conical grinding shell, and the other end of each of the multiple support rods is slidably adapted to the annular groove.

[0007] The feeding and discharging mechanism includes a feeding hopper, a guide pipe, and a leak-proof plate. The feeding hopper is connected to the upper end of the housing, the guide pipe is connected to the lower end of the feeding hopper and is located inside the housing, and the leak-proof plate is fixedly connected to the upper end of the conical grinding shell.

[0008] The feeding and discharging mechanism also includes a discharge pipe, one end of which passes through the bottom of the box and is fixedly connected to the bottom of the conical grinding shell.

[0009] The fine grinding mechanism further includes a filter screen groove, a rotating rod, and a second motor. The filter screen groove is fixedly connected to the lower end of the housing and is located directly below the discharge pipe. The second motor is fixedly connected to the lower end of the housing. The rotating rod is fixedly connected to the output end of the second motor, and one end of the rotating rod is located inside the filter screen groove.

[0011] This utility model discloses a grinding device for silica sand production. Tailings material is placed between a conical grinding block and a conical grinding shell. The output of a first motor drives a gear to rotate, which in turn drives the gear ring and the conical grinding shell to rotate. The gap between the conical grinding shell and the conical grinding block is smaller than the diameter of the tailings material. Through this gap fit, the tailings material is ground.

[0021] This utility model provides a grinding device for silica sand production, including a housing 101, a fine grinding mechanism, a feeding and discharging mechanism, and a support 102. The fine grinding mechanism includes a conical grinding block 103, a conical grinding shell 104, a toothed ring 105, a gear 106, multiple support rods 107, a first motor 108, a support plate 109, a filter screen groove 110, a rotating rod 111, and a second motor 112. The feeding and discharging mechanism includes a feeding hopper 113, a guide pipe 114, a leak-proof plate 115, and a discharge pipe 116. The inner bottom wall of the housing 101 has an annular groove 117.

[0022] In this specific embodiment, tailings material is placed between the conical grinding block 103 and the conical grinding shell 104. Then, the output end of the first motor 108 drives the gear 106 to rotate, which in turn drives the gear ring 105 and the conical grinding shell 104 to rotate. The gap between the conical grinding shell 104 and the conical grinding block 103 is smaller than the diameter of the tailings material. Through the gap fit between the conical grinding shell 104 and the conical grinding block 103, the tailings material is ground. After the tailings material is ground, it falls and is discharged from the bottom. When the conical grinding shell 104 rotates, the stability of the conical grinding shell 104 is improved by the cooperation of multiple support rods 107 and the annular groove 117. Thus, this device can grind and extract tailings, thereby increasing the content of ultrafine powder in the tailings, reducing production costs, and achieving efficient resource utilization.

[0023] The conical grinding block 103 is fixedly connected to the inner top wall of the housing 101. The conical grinding shell 104 is disposed inside the housing 101 and located at the lower end of the conical grinding block 103. The toothed ring 105 is fixedly sleeved on the outside of the conical grinding shell 104. The gear 106 is adapted to the toothed ring 105. The support plate 109 is fixedly connected to the inner wall of the housing 101. The first motor 108 is disposed at the upper end of the support plate 109. The output end of the first motor 108 is fixedly connected to the gear 106. One end of each of the plurality of support rods 107 is fixedly connected to the lower end of the conical grinding shell 104, and the other end of each of the plurality of support rods 107 is slidably adapted to the annular groove 117. Tailings material is placed between the conical grinding block 103 and the conical grinding shell 104. Then, the output end of the first motor 108 drives the gear 106 to rotate, which in turn drives the gear ring 105 and the conical grinding shell 104 to rotate. The gap between the conical grinding shell 104 and the conical grinding block 103 is smaller than the diameter of the tailings material. Through the gap fit between the conical grinding shell 104 and the conical grinding block 103, the tailings material is ground. After the tailings material is ground, it falls and is discharged from the bottom. When the conical grinding shell 104 rotates, the stability of the conical grinding shell 104 is improved by the cooperation of multiple support rods 107 and the annular groove 117. Thus, this device can grind and extract tailings, thereby increasing the content of ultrafine powder in the tailings, reducing production costs, and achieving efficient utilization of resources.

[0024] Secondly, the feed hopper 113 is connected to the upper end of the housing 101, the guide pipe 114 is connected to the lower end of the feed hopper 113 and is located inside the housing 101, and the leak-proof plate 115 is fixedly connected to the upper end of the conical grinding shell 104. Before grinding, the tailings material is poured into the feed hopper 113, and then flows through the guide pipe 114 into the space between the conical grinding block 103 and the conical grinding shell 104. The leak-proof plate 115 can prevent the tailings material from spilling out, and can also prevent the tailings material from accumulating on the upper end of the conical grinding shell 104 during grinding and easily spilling out.

[0025] Meanwhile, one end of the discharge pipe 116 passes through the bottom of the housing 101 and is fixedly connected to the bottom of the conical grinding shell 104. After the tailings material is ground, it will gradually fall to the bottom and then be discharged through the discharge pipe 116 at the bottom.

[0026] In addition, the filter screen trough 110 is fixedly connected to the lower end of the housing 101 and is located directly below the discharge pipe 116. The second motor 112 is fixedly connected to the lower end of the housing 101, and the rotating rod 111 is fixedly connected to the output end of the second motor 112. One end of the rotating rod 111 is located inside the filter screen trough 110. When the tailings material is discharged, it is filtered through the filter screen trough 110 to screen out ultrafine powder. The output end of the second motor 112 drives the rotating rod 111 to rotate, and the second motor 112 can rotate clockwise and counterclockwise, that is, drive the rotating rod 111 to rotate clockwise and counterclockwise, thereby pushing the material accumulated on the filter screen trough 110, thus preventing the material from accumulating and becoming unfilterable.

[0027] Furthermore, the bracket 102 is fixedly connected to the lower end of the housing 101. The bracket 102 provides load-bearing support for the housing 101.

[0028] When using the grinding device for silica sand production of this utility model, the tailings material is placed between the conical grinding block 103 and the conical grinding shell 104. Then, the output end of the first motor 108 drives the gear 106 to rotate, thereby driving the gear ring 105 and the conical grinding shell 104 to rotate. The gap between the conical grinding shell 104 and the conical grinding block 103 is smaller than the diameter of the tailings material. Through the gap fit between the conical grinding shell 104 and the conical grinding block 103, the tailings material is ground. After the tailings material is ground, it falls and is discharged from the bottom. When the conical grinding shell 104 rotates, the stability of the conical grinding shell 104 is improved by the cooperation of multiple support rods 107 and the annular groove 117. Thus, this device can grind and extract tailings, thereby improving the ultrafine content of the tailings. The fine powder content is reduced, thereby lowering production costs and achieving efficient resource utilization. Before grinding, the tailings material is poured into the feed hopper 113, and then flows through the guide pipe 114 between the conical grinding block 103 and the conical grinding shell 104. The anti-leak plate 115 prevents the tailings material from spilling out, and also prevents the tailings material from accumulating on the upper part of the conical grinding shell 104 during grinding and not falling down in time, which could easily lead to spillage. After the tailings material is ground, it will gradually fall to the bottom and be discharged through the discharge pipe 116 at the bottom. After the tailings material is discharged, it is filtered through the filter screen trough 110 to screen out ultrafine powder. The output end of the second motor 112 drives the rotating rod 111 to rotate, thereby pushing the material accumulated on the filter screen trough 110, thus preventing the material from accumulating and being unable to be filtered and separated.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
