Description

Technical Field

[0001] This utility model relates to the field of coal preparation and separation bed technology, specifically to dry coal preparation and separation bed. Background Technology

[0002] Dry coal preparation refers to the method of separating coal under dry conditions. A search revealed an existing patent (publication number: CN213557659U) that discloses a jigging dry coal preparation machine. The machine includes a body with mounting rods symmetrically welded to its inner side. Connecting columns are symmetrically slidably inserted into the surfaces of the mounting rods. A separation bed is welded to the upper end of each connecting column. A first spring is sleeved on the surface of the connecting column, with the separation bed welded to the upper end of the first spring and the mounting rod welded to the lower end. A vibrating motor is mounted on the lower surface of the separation bed. This jigging dry coal preparation machine uses two vibrating motors to drive the separation bed to vibrate up and down, and is used to separate materials with small particle sizes. It is simple to operate, highly efficient, has good separation effect, and low power consumption.

[0003] It can sort coal with smaller particle sizes, but it has shortcomings. It uses a height-limiting baffle to prevent small coal particles from moving to the right. However, if the coal moves to the right, it will be discharged from the first discharge port. As the coal descends, larger coal particles will block the first discharge port, affecting the discharge of small coal particles. Utility Model Content

[0011] Beneficial effects

[0012] This utility model provides a dry coal preparation separation bed. Compared with the prior art, it has the following advantages:

[0013] 1. This dry coal preparation and separation bed is equipped with a fine coal discharge pipe, a coarse coal discharge pipe, a motor, a rotating rod, and a conveyor belt. Coal enters the dustproof shell from the feed hopper and then falls onto the bed. Small coal particles are discharged from the fine coal discharge pipe, while large coal particles are blocked and cannot fall. The motor is started, and the motor drives the connecting rod and the rotating rod at the rear to rotate. The rotating rod at the rear drives the conveyor belt to rotate, and the conveyor belt transports the blocked large coal particles to the rear, where they are discharged from the coarse coal discharge pipe. This completes the coal separation.

[0014] 2. This dry coal preparation and separation bed, by setting an adjustment mechanism, loosens the fixing nut and moves the screw. The screw moves the connecting block and the moving plate. The movement of the moving plate can adjust the size of the upper inlet of the fine coal discharge pipe, thus controlling the separation volume of fine coal materials. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a dry coal preparation and separation bed, including a bed body 12, a dustproof shell 6 fixed to the outside of the bed body 12, a baffle 11 fixed to the top of the bed body 12, a fixing plate 3 fixed to the bottom of the dustproof shell 6, two rotating rods 21 fixed to the top of the fixing plate 3, a conveyor belt 8 sleeved on the outside of the two rotating rods 21, a connecting rod 23 fixed to the top of the rear rotating rod 21, a motor 5 fixed to the top of the dustproof shell 6, the output shaft of the motor 5 passing through the dustproof shell 6 and the top of the connecting rod 23 and fixedly connected, a fine coal discharge pipe 2 fixed to the bottom of the fixing plate 3, and a fine coal discharge pipe 2 fixed to the rear end of the dustproof shell 6. There is a coarse coal discharge pipe 4, a vibrator 13 is fixed at the bottom of the bed body 12, and multiple support legs 1 are fixed at the bottom of the bed body 12, which can sort the coal. A support plate 10 is fixed inside the right side of the dustproof shell 6. The top of the rotating rod 21 is rotatably connected to the bottom of the support plate 10. The connecting rod 23 passes through the support plate 10. A reinforcing plate 22 is provided inside the conveyor belt 8 between the two rotating rods 21. The top and bottom of the reinforcing plate 22 are fixedly connected to the fixed plate 3 and the support plate 10 respectively, which can hold the conveyor belt 8. A feed hopper 7 is fixed at the top of the dustproof shell 6, which facilitates feeding.

[0022] Furthermore, the bed body 12 is equipped with an adjustment mechanism 9, which includes a movable plate 20 located inside the bed body 12. This allows for adjustment of the inlet size of the fine coal discharge pipe 2. An opening 19 is provided at the bottom of the bed body 12, and a connecting block 18 is provided inside the opening 19. The top of the connecting block 18 is fixedly connected to the bottom of the movable plate 20. A fixing block 16 is fixedly provided at the bottom of the bed body 12, and a screw 14 is provided inside the fixing block 16. The right end of the screw 14 is fixedly connected to the left side of the connecting block 18. Fixing nuts 15 are screwed onto the outer side of the screw 14 on both the left and right sides of the fixing block 16 to fix the movable plate 20. Two reinforcing nuts 17 are screwed onto the outer side of the screw 14 outside the two fixing nuts 15 to enhance the stability of the fixing nuts 15.

[0023] During operation, coal enters the dustproof shell 6 from the feed hopper 7 and falls onto the bed 12. The vibrator 13 is activated, causing the bed 12 to vibrate and slide the coal to the right, simultaneously shaking smaller pieces of coal to the bottom. These smaller pieces are discharged from the fine coal discharge pipe 2. Larger pieces of coal are blocked and cannot fall. The motor 5 is then activated, causing the connecting rod 23 and the rear rotating rod 21 to rotate. The rear rotating rod 21 drives the conveyor belt 8 to rotate, transporting the blocked larger pieces of coal to the rear, where they are discharged from the rear coarse coal discharge pipe 4. This completes the coal sorting process. If it is necessary to sort smaller pieces of coal of different sizes, the fixing nut 15 can be loosened, and the screw 14 can be moved. The screw 14 moves the connecting block 18 and the moving plate 20. Moving the moving plate 20 adjusts the size of the upper inlet of the fine coal discharge pipe 2, thus controlling the sorting volume of smaller pieces of coal.
