Description

Technical Field

[0001] This utility model relates to the field of coal mine spoil separation technology, specifically to an open-pit coal mine spoil separation device. Background Technology

[0002] A coal mine encompasses a large area, including both above-ground and underground facilities. A coal mine is a specially excavated space created by humans when mining coal-rich geological strata, typically including tunnels, shafts, and working faces. Coal is the most important solid fuel and is a type of combustible organic rock. It is formed from abundant vegetation that grew over a specific geological era, gradually accumulating into thick layers under suitable geological conditions, buried underwater or in silt, and undergoing natural coalification over long geological periods.

[0003] A search of existing patent number CN202122066678.8 reveals a patent titled "A Coal Mine Sediment Separation Device for Coal Mining." The device includes a first processing tank with an inlet at its top, a filter tank inside, a water outlet on the surface of the filter tank, a water storage tank on one side of the inner wall of the first processing tank, a first water supply pipe at its top, a second water supply pipe inside the water storage tank, a first water pump on the surface of the second water supply pipe, and a spray plate connected to one end of the second water supply pipe. This device uses a vibrating motor to rapidly vibrate the coal entering the filter tank, causing the surface sediment to be quickly shaken off after being washed by the spray plate, thus improving the efficiency of sediment separation. Simultaneously, the coal inside the filter tank can be quickly pushed out by a push plate, facilitating the collection of processed coal and improving the overall efficiency of coal separation.

[0004] However, the water spray plate of the above-mentioned device is in a fixed position, and can only wash the mud and sand on the surface of the coal mine. The washing and separation effect is poor and not comprehensive enough. Utility Model Content

The washed water and silt flow into the separation tank, and the water is reused after filtration. The washed coal is discharged from the discharge port, which can continuously separate the coal and improve the separation efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example 1:

[0025] Please see Figure 1-4This utility model provides a technical solution: a separation box 1, with an inspection cover 2 on the top of the separation box 1, a feeding port 3 on the top of the inspection cover 2, a discharge port 4 on one side of the separation box 1, a separation assembly 5 on the separation box 1, the separation assembly 5 including a drive roller 505 rotatably connected inside the separation box 1, a conveyor belt 507 drivingly connected to the surface of the drive roller 505, a driven roller 506 rotatably connected inside the conveyor belt 507, baffles 508 evenly distributed on the surface of the conveyor belt 507, filter holes 509 on the surface of the conveyor belt 507, and a first power pulley 5 rotatably connected to one side of the separation box 1. 03. The first power pulley 503 is fixedly connected to the drive roller 505. A motor 501 is fixedly installed on one side of the separation box 1. The output shaft of the motor 501 is fixedly connected to the drive pulley 502. The drive pulley 502 and the first power pulley 503 are connected by a first transmission belt 504. A water pump 510 is fixedly connected to the top of the inspection cover 2. A conveying pipe 511 is fixedly connected inside the separation box 1. Spray nozzles 512 are evenly distributed and connected to the bottom of the conveying pipe 511. The conveying pipe 511 is fixedly connected to the outlet of the water pump 510. The inlet of the water pump 510 is fixedly connected to the bottom of the separation box 1.

[0026] Analysis of the above content: A separation component 5 is set up. The motor 501 drives the drive pulley 502 to rotate, which in turn drives the first power pulley 503 to rotate under the action of the first transmission belt 504. This causes the conveyor belt 507 and the baffle 508 to move the coal to be separated upward along the conveyor belt 507. The water pump 510 draws water out of the separation box 1, and the water flows into the conveying pipe 511 and sprays out from the nozzle 512 to wash the coal. Because the coal is moving, the washing effect and the washing area of ​​the coal are improved, thus improving the separation effect. The washed water and mud flow into the separation box 1, and the water is reused after filtration. The washed coal is discharged from the discharge port 4, which can continuously separate the coal and improve the separation efficiency.

[0027] Example 2:

[0028] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: the separation component 5 further includes a cam 517 rotatably connected within the separation box 1. A connecting pulley 515 is fixedly connected to one side of the cam 517. The two sets of connecting pulleys 515 are connected by a third transmission belt 516. A second power pulley 513 is fixedly connected to one side of each set of connecting pulleys 515. The second power pulley 513 and the drive pulley 502 are connected by a second transmission belt 514. The second power pulley 513 has the same diameter as the connecting pulleys 515, and the diameter of the drive pulley 502 is larger than the diameter of the second power pulley 513.

[0029] Analysis of the above content: When the active pulley 502 rotates, it drives the second power pulley 513 and the connecting pulley 515 to rotate, thereby causing the cam 517 to rotate, which in turn drives the conveyor belt 507 to vibrate up and down, causing the coal mine to shake, further improving the washing and separation effect of the coal mine.
