Description

Technical Field

[0001] This utility model relates to the field of sorting device technology, and in particular to a gangue sorting device for underground use. Background Technology

[0002] Coal, as my country's primary energy source, accounts for a significant proportion of the national economy. Every year, coal mining causes extensive land subsidence and the formation of large amounts of waste rock piles, which continue to increase annually. These waste rock piles not only occupy vast amounts of land resources on the surface but also cause environmental pollution and pose a risk of spontaneous combustion; the ineffective hoisting of waste rock underground results in a waste of energy from mining equipment.

[0003] Based on the concepts of environmental protection and green mining, if some of the gangue in raw coal is sorted before being brought to the surface and used as backfill material in the mined-out area, the intelligent sorting and backfilling of gangue in the mine can be organically combined with the mining process. This integrates underground coal mining with the sorting and backfilling systems, achieving integrated underground raw coal mining, sorting, and backfilling. This can reduce surface gangue pollution, improve coal quality, achieve energy conservation and emission reduction, benefit environmental protection, and meet the requirements for building a green mine. However, the screening process involves high dust content. Underground screening not only pollutes the environment but also affects air quality in the confined space of the mine, increasing the respiratory burden on workers. Furthermore, high dust content poses safety hazards underground. Therefore, we propose an underground gangue sorting device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a gangue sorting device for underground use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gangue sorting device for underground use, comprising a base plate, a pump casing, a support frame, a mounting frame, a screen casing, and a motor. The support frame is mounted on the upper end of the base plate, and the screen casing is mounted above the support frame. A screen mesh is installed inside the screen casing. A first rotating shaft and a second rotating shaft are rotatably mounted above the base plate. A wheel is mounted at one end of the first rotating shaft, and a striking block is mounted at the lower end of the wheel. A force-bearing block is mounted at the lower end of the mounting frame. An impeller rotatably mounted inside the pump casing is sleeved on the outer wall of the second rotating shaft. A top cover is mounted on the upper end of the screen casing, and a housing is mounted on one side of the screen casing. Equally spaced guide rods are mounted at the lower end of the mounting frame, and equally spaced sliding sleeves are mounted on the upper end of the support frame. A limiting ring is sleeved on the outer wall of each guide rod, and a spring is installed between the limiting ring and the sliding sleeve.

[0006] Preferably, one end of the guide rod is slidably inserted into the inside of the sliding sleeve, and the spring is sleeved on the outside of the guide rod. The guide rod slides inside the sliding sleeve, obtaining sliding support, and because it is located inside the spring, it limits the spring and prevents the spring from shifting outward during extension and contraction.

[0007] Preferably, the support frame has a travel groove inside, and both the striking block and the force-receiving block correspond to the travel groove. The travel groove provides a path for the rotation of the striking block, effectively allowing it to contact the force-receiving block through the support frame.

[0008] Preferably, the screening shell has a feed inlet located above the screen mesh at one end, and an upper discharge outlet at the other end. The ore is fed into the screening shell through the feed inlet and discharged from the sorting section through the upper discharge outlet.

[0009] Preferably, a separation trough is provided below the screen and inside the screen housing, with a lower discharge port penetrating the screen housing at one end. The separation trough is used to screen the ore, which is then intercepted by the coal-rock separation trough and discharged through the lower discharge port.

[0010] Preferably, the housing and the top cover are connected by a second suction pipe, and the pump casing suction end is connected to the housing by a first suction pipe, with the first suction pipe corresponding to the second suction pipe. The first suction pipe transmits the suction force to the second suction pipe, and the suction force of the second suction pipe acts on the screen housing through the top cover to draw in the dispersed dust.

[0011] Preferably, a filter screen is installed on one side of the suction pipe that penetrates the interior of the housing, and a guide plate is installed on the inner wall of one side of the housing below the filter screen. The filter screen prevents the suctioned dust from entering the suction pipe, and the guide plate guides the downward-falling dust.

[0012] Preferably, a transmission wheel set one is sleeved on both the motor output end and the outer wall of the rotating shaft one, and a transmission wheel set two is sleeved on both the motor output end and the outer wall of the rotating shaft two.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When the motor-driven rotary wheel of this utility model drives the striking block to rotate, it pushes the force block at the lower end of the mounting frame. When the striking block passes the force block, the mounting frame swings back and forth through the elastic element, thereby screening the mineral material on the screen. Coal and ore are screened out. The waste generated during the sorting process is treated and recycled, reducing the impact on the environment. At the same time, the dust is extracted during the screening process, reducing the impact on the environment and workers, and reducing the safety hazards caused by high dust content.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, this utility model proposes a gangue sorting device for underground use, including a base plate 1, a pump casing 2, a support frame 3, a mounting frame 4, a screen shell 5, and a motor 23. The support frame 3 is provided on the upper end of the base plate 1, and the screen shell 5 is provided above the support frame 3. A screen 18 is provided inside the screen shell 5. A rotating shaft 28 and a rotating shaft 29 are rotatably mounted on the upper end of the base plate 1. A rotating wheel 26 is provided at one end of the rotating shaft 28, and a striking mechanism is provided at the lower end of the rotating wheel 26. Block 27, the lower end of the mounting frame 4 is provided with a force-bearing block 22, the outer wall of the rotating shaft 29 is sleeved with an impeller 30 that is rotatably installed inside the pump casing 2, the upper end of the screen casing 5 is provided with a top cover 7, the side of the screen casing 5 is provided with a box body 9, the lower end of the mounting frame 4 is provided with guide rods 16 that are evenly distributed, the upper end of the support frame 3 is provided with sliding sleeves 13 that are evenly distributed, the outer wall of the guide rods 16 is sleeved with a limit ring 15, and a spring 14 is provided between the limit ring 15 and the sliding sleeve 13;

[0023] One end of the guide rod 16 is slidably inserted into the inside of the sliding sleeve 13, and the spring 14 is sleeved on the outside of the guide rod 16;

[0024] The support frame 3 has a stroke groove 21 inside, and the striking block 27 and the force-bearing block 22 both correspond to the stroke groove 21;

[0025] The screen shell 5 has a feed inlet 6 located above the screen 18 at one end, and an upper discharge outlet 12 at the other end.

[0026] Below the screen 18 is a separation groove 17 located inside the screen shell 5, and one end of the separation groove 17 has a lower discharge port 11 that penetrates the screen shell 5.

[0027] The housing 9 and the top cover 7 are connected by suction pipe 2 8, and the suction end of the pump housing 2 is connected to the housing 9 by suction pipe 10. Suction pipe 10 corresponds to suction pipe 2 8.

[0028] The suction tube 2 8 penetrates the interior of the box 9 and is equipped with a filter screen 19 on one side. A guide plate 20 located below the filter screen 19 is provided on the inner wall of one side of the box 9.

[0029] A transmission wheel set 24 is sleeved on both the output end of motor 23 and the outer wall of shaft 28, and a transmission wheel set 25 is sleeved on both the output end of motor 23 and the outer wall of shaft 29.

[0030] Based on the implementation steps of Embodiment 1: Motor 23 drives the output shaft to rotate, which in turn drives the rotating shaft 28 to rotate via transmission wheel set 24. Both transmission wheel set 24 and transmission wheel set 25 include pulleys and belts. Transmission wheel set 24 drives the large wheel to rotate via a small wheel, thereby reducing the rotation of the rotating shaft 28 and the rotating wheel 26. The striking block 27 rotates with the rotating wheel 26 and applies a compressive force to the force-bearing block 22 when passing through the stroke groove 21, thereby pushing the support frame 3 to move. The bottom of the support frame 3 is connected by guide rod 16. The sliding support, the guide rod 16, applies a pulling force to the spring 14 as it moves with the support frame 3. When the force block 22 stops being squeezed, the spring 14 drives the support frame 3 to shake laterally through its own elasticity, thereby screening the ore on the screen 18. The ore is input through the feed port 6 and screened through the screen 18. Coal ore suitable for backfilling is screened out, realizing the direct utilization of coal ore and avoiding the need to transport it to the surface through conveying equipment, which not only occupies land, but also has a coal gangue separation particle size of 50mm.

[0031] The output of motor 23 simultaneously drives shaft 29 to rotate, which is linked by transmission wheel set 25. The larger wheel drives the smaller wheel to rotate, thus accelerating shaft 29 and driving impeller 30 to generate a strong suction force inside pump casing 2. The dust below top cover 7 is sucked in through suction pipe 10 and suction pipe 28. The dust emitted during the ore screening process is collected. The dust emitted during screening pollutes the underground environment and increases the respiratory burden on workers, thus reducing safety hazards. Because the displacement power equipment used in the screening process is motor 23, the use of power equipment is reduced, the operating cost is reduced, and it is in line with the concept of environmental protection.

[0032] The above specific embodiments are merely several preferred embodiments of this utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
