Description

Technical Field

[0001] The utility model relates to the technical field of coal washing, in particular to an anti-clogging coal washing device. Background Art

[0002] Coal washing generally refers to the process of removing gangue or other impurities from coal. Coal washing generally utilizes the differences in physical properties between coal and gangue, separating them in media of varying densities or characteristics. Physical coal separation involves separating coal and impurities based on differences in their physical properties (such as particle size, density, hardness, magnetic properties, and electrical properties). The main physical separation methods include gravity separation, including jigging, heavy media separation, chute separation, shaking table separation, and pneumatic separation.

[0003] In the existing coal washing process, a feeding device is required to discharge the crushed coal onto a conveyor belt to facilitate subsequent washing. However, the crushed coal is small in volume and has not undergone processes such as drying. As a result, the coal will clump together after being squeezed. Most of the existing feeding devices do not have a structure to crush the coal lumps when in use. As a result, some large pieces of coal will block the feeding device, thereby affecting the normal use of the device.

[0004] At the same time, when the existing unloading device is in use, its interior is mostly smooth in design. However, coal with a high water content will adhere to the inner wall of the device after being squeezed, resulting in a large amount of residual material remaining inside the device. In addition, the middle part of the device will discharge material, and the edge part will all hang on the inner wall of the device, affecting the normal unloading of coal by the device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

DETAILED DESCRIPTION

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-4As shown, a coal washing device for preventing blockage includes a feeding hopper 1, which is used to store coal so as to facilitate uniform discharge of the coal. Support frames 2 are fixedly connected to both sides of the surface of the feeding hopper 1. The support frames 2 are used to support the feeding hopper 1, so as to facilitate the device to discharge the coal to the surface of the conveyor belt. A servo motor 3 is bolted to the surface of the support frame 2 on one side. A rotating rod 4 is provided inside the feeding hopper 1. Both ends of the rotating rod 4 pass through the outside of the feeding hopper 1 and are rotatably connected to the inner wall of the penetration point. Both ends of the rotating rod 4 are installed with a first bevel gear set 5. The first bevel gear set 5 consists of two bevel gears meshing with each other, so as to facilitate power transmission. The output shaft of the servo motor 3 is fixed to the surface of the first bevel gear set 5 on one side. Fixed connection, under this action, when the servo motor 3 rotates, the rotating rod 4 can be rotated through the first bevel gear set 5. The surface of the rotating rod 4 is installed with a stirring mechanism 6, which can stir the inside of the feeding hopper 1 through the power when the rotating rod 4 rotates, thereby reducing the coal agglomerates inside the feeding hopper 1 and preventing the wet agglomerated coal from clogging the discharge port of the feeding hopper 1 and affecting the normal use of the device. Both sides of the feeding hopper 1 are connected with a fixed shell 7, and the inner cavity of the fixed shell 7 is slidably connected with a push plate 8. The inclined structure design on one side of the push plate 8 can block the coal under this action to prevent the coal from entering the interior of the fixed shell 7 and affecting the normal movement of the push plate 8. One side of the push plate 8 is fixedly connected with a tension spring 9. There are several 9, and the other end of the tension spring 9 is fixedly connected to the inner wall of the fixed shell 7. Under this action, the push plate 8 can be returned to its original position through the cooperation of the tension spring 9 after moving, so as to facilitate the subsequent use of the push plate 8. A fixed rod 10 is installed on the surface of the first bevel gear set 5, and a cam 11 is fixedly connected to the surface of the fixed rod 10. A through slot 12 is provided on one side of the fixed shell 7, and the through slot 12 is used in conjunction with the cam 11. Under this action, when the servo motor 3 rotates, the fixed rod 10 can drive the cam 11 to rotate through the cooperation of the first bevel gear set 5, thereby pushing the push plate 8 to push the coal inside the feeding hopper 1, thereby reducing the situation where the coal sticks to the inside of the feeding hopper 1, and when the tension spring 9 and the cam 11 are in contact, the cam 11 is pulled back to the original position. The cooperation can make the pushing plate 8 move back and forth, so as to lift the coal remaining inside the device. One side of the pushing plate 8 is fixedly connected to a guide rod 14, and the other end of the guide rod 14 passes through the outer side of the fixed shell 7 and is slidably connected to the inner wall of the penetration point. Under this action, the pushing plate 8 can be guided when it moves, so that the pushing plate 8 is more stable when moving, and the tension spring 9 can also be limited so that it will not have a large position offset during the stretching and rebound process, avoiding the tension spring 9 from being unstable during use and affecting the rebound effect of the pushing plate 8. The surface of the fixed rod 10 is rotatably connected to a support seat 15, and one side of the support seat 15 is fixedly connected to the surface of the fixed shell 7. Under this action, the fixed rod 10 can be supported.This makes the fixed rod 10 more stable when rotating, and avoids the fixed rod 10 being unstable when rotating and affecting the pushing effect of the cam 11 on the pushing plate 8.

[0023] The stirring mechanism 6 includes a second bevel gear set 61, which is the same as the first bevel gear set 5. One side of the second bevel gear set 61 is fixedly connected to the surface of the rotating rod 4, and a connecting rod 62 is installed on the top of the second bevel gear set 61. Both sides of the surface of the connecting rod 62 are fixedly connected with stirring rods 63. There are several stirring rods 63. Under this action, the rotating rod 4 can be rotated through the cooperation of the second bevel gear set 61 to make the connecting rod 62 drive the stirring rod 63 to rotate, thereby disturbing the coal inside the feeding hopper 1, thereby reducing the situation where the coal blocks the discharge port of the feeding hopper 1, effectively improving the applicability of the device, and a protective shell 13 is fixedly connected to the bottom of the inner cavity of the feeding hopper 1. The second conical gear set 61 is fixedly connected to the bottom of the inner cavity of the feeding hopper 1. The gear set 61 is located inside the protective shell 13, and the inner wall of the protective shell 13 is rotatably connected to the surface of the rotating rod 4 and the connecting rod 62. Under this action, the protective shell 13 can protect the second bevel gear set 61 to prevent the coal from easily contacting the second bevel gear set 61 and affecting its normal rotation, and to prevent the coal from being stuck on the surface of the second bevel gear set 61 and affecting the normal rotation of the connecting rod 62 and the stirring rod 63. The top of the connecting rod 62 is rotatably connected to the mounting bracket 16, and the surface of the mounting bracket 16 is fixedly connected to the inner wall of the feed hopper 1. Under this action, one end of the connecting rod 62 can be supported, so that the connecting rod 62 will not shake significantly during rotation, effectively improving the stability of the connecting rod 62 during rotation.

[0024] It is worth noting that the technical features such as the feeding hopper 1 and the support frame 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: First, pour the coal to be washed into the inside of the feed hopper 1, and then the staff turns on the servo motor 3. Under the action of the servo motor 3, the rotating rod 4 will rotate through the cooperation of the first bevel gear set 5, and the rotating rod 4 will drive the second bevel gear set 61 to rotate when rotating, so that the connecting rod 62 and the stirring rod 63 rotate inside the feed hopper 1, thereby disturbing the coal and reducing the large pieces of coal formed by squeezing inside the feed hopper 1. Not only can the discharge of the device be more uniform, but also the blockage of the device can be reduced. When the first bevel gear set 5 rotates, it will also drive the fixed rod 10 to rotate. When the fixed rod 10 rotates, the through slot 12 will push the push plate 8 to move, thereby reducing the coal adhering to the inside of the feed hopper 1, so that the discharge of the device can be more thorough. With the cooperation of the tension spring 9 and the cam 11, the push plate 8 can be moved back and forth, thereby reducing the residual coal inside the feed hopper 1.
