Abstract
Description
Technical Field
[0001] This utility model relates to the field of dewatering machine technology, and in particular to a dewatering machine for coal washing. Background Technology
[0002] Coal washing separates raw coal of different compositions and specific gravities into different grades by the impact of water flow, removing dust and waste rock, and reducing ash and sulfur content. In coal washing plants, the washed coal needs to be dewatered. Most dewatering methods used in coal washing employ dewatering machines. Nowadays, most dewatering machines are reinforced with supports. However, during the dewatering of large coal blocks, the dewatering machine is still prone to movement due to inertia, and the internal rollers may even collide with the inner wall, causing damage. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a dewatering machine for coal washing.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dewatering machine for coal washing, including a dewatering machine body, two symmetrical brush assemblies are arranged inside the dewatering machine body, a roller assembly is arranged between the two brush assemblies, two symmetrical foot column assemblies are arranged outside the dewatering machine body, a support column assembly is arranged between the symmetrical foot column assemblies, a palm plate assembly is arranged outside each foot column assembly, the palm plate assembly includes two symmetrical trays, a damping rod is arranged between the two trays, and several airbag rods are also arranged between the two trays, and three fixing components are arranged outside each palm plate assembly.
[0005] As a preferred technical solution of this utility model, the roller assembly includes a bottom plate, an outer cylinder fixedly connected to the outside of the bottom plate, an inner cylinder provided inside the outer cylinder and also fixedly connected to the bottom plate, a shaft provided outside the bottom plate and the shaft penetrating the bottom plate, a connecting rod provided on the side of the shaft away from the motor, and the inner cylinder and the outer cylinder fixedly connected at both ends of the connecting rod.
[0006] As a preferred technical solution of this utility model, the brush assembly includes a fixing tube, a scraper fixedly connected to the outside of the fixing tube, and several round brushes fixedly connected to the outside of the fixing tube.
[0007] As a preferred technical solution of this utility model, each foot column assembly includes a support column, and an annular spring is provided on the outside of the support column. Limiting plates are provided at both ends of the annular spring, and the annular spring is made of elastic metal.
[0008] As a preferred technical solution of this utility model, the fixing components all include nail sleeves, and ground nails are provided on the side of the nail sleeve away from the main body of the dewatering machine. The ground nails can be moved through the nail sleeves. Two elastic rods are provided on the side of the nail sleeve close to the main body of the dewatering machine. One end of each elastic rod is fixedly connected to the nail sleeve, and the other end is fixedly connected to the tray.
[0009] As a preferred technical solution of this utility model, the pier assembly includes a core column, three shock-absorbing rings are provided on the outside of the core column, and a load-bearing plate is fixedly connected to the side of the core column away from the main body of the dewatering machine. The shock-absorbing rings are made of rubber material.
[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are:
[0011] 1. By setting up a foot column assembly, when the dehydrator is running at full load and generates huge swaying, the main body of the dehydrator pushes the foot column assembly to deform and absorb the thrust. The foot column assembly pushes the palm plate assembly to compress it, thereby greatly reducing the lateral swaying of the dehydrator. At the same time, the tray in the palm plate assembly has a large contact area, so it can ensure that the dehydrator will not sink when running on the ground.
[0012] 2. By setting up a fixing component, when the dewatering machine is used on soft soil, technicians can insert ground nails into the ground to stabilize the main body of the dewatering machine. At the same time, the elastic rod is fixedly connected to the tray. When the tray shakes, the rubber material of the elastic rod can reduce the degree of shaking of the tray, thereby further reducing the shaking of the palm plate assembly. This ensures that the position of the main body of the dewatering machine will not move due to inertia during operation, thus improving the stability of the dewatering machine during operation.
[0013] 3. By setting up a support column assembly, when the dewatering machine is running at full load and generates huge shaking, the main body of the dewatering machine pushes the core column to compress it. During the compression process of the core column, it pushes the shock-absorbing ring to compress and deform, thereby reducing the thrust generated by the main body of the dewatering machine. This reduces the collision between the inner wall of the dewatering machine body and the outer cylinder, ensuring the operating efficiency of the dewatering machine and extending its service life.
[0014] 4. By setting up a drum assembly, when the dewatering machine dewaters large coal blocks, the motor output shaft drives the shaft rod to rotate, which in turn drives the connecting rod to rotate. The two ends of the connecting rod are fixedly connected to the inner cylinder and the outer cylinder. The outer cylinder is fixedly connected to the bottom plate, and the inner cylinder is also fixedly connected to the bottom plate, thereby ensuring the safety of the dewatering machine's internal operation when the dewatering machine rotates at high speed.
[0015] 5. By setting up a brush assembly, when the dewatering machine is running, some dissolved coal sludge will adhere to the outer cylinder during the dewatering process. During the rotation of the outer cylinder, the circular brush will rub against the outer cylinder to remove the coal sludge. At the same time, the oblique scraper will scrape off the coal sludge adhering to the outer cylinder, thus avoiding clogging during the operation of the dewatering machine and ensuring the efficiency of the dewatering machine.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0024] Example: Figure 1 , Figure 3 and Figure 4 A coal washing dewatering machine includes a dewatering machine body 10 and a motor. The motor is of a model such as YBX4 manufactured by Nanyang Explosion-proof Micro Motor Co., Ltd. The motor is fixedly connected to the outside of the dewatering machine body 10. The inner wall of the dewatering machine body 10 is provided with two symmetrical brush assemblies 70. The brush assembly 70 includes a fixing pipe 702. One side of the fixing pipe 702 is fixedly connected to the inner wall of the dewatering machine body 10, and a scraper 701 is fixedly connected to the other side of the fixing pipe 702. Several circular brushes 703 are fixedly connected to the side of the fixing pipe 702 away from the inner wall of the dewatering machine body 10.
[0025] A roller assembly 40 is provided between the two brush assemblies 70. The roller assembly 40 includes a bottom plate 403. The motor output shaft passes through the bottom plate 403 and is fixedly connected to it. An outer cylinder 401 and an inner cylinder 402 are fixedly connected to the side of the bottom plate 403 away from the motor. The outer cylinder 401 is sleeved on the outside of the inner cylinder 402. Both the outer cylinder 401 and the inner cylinder 402 are provided with several leakage holes. A shaft rod 404 is fixedly connected to the motor output shaft. A connecting rod 405 is fixedly connected to the outside of the shaft rod 404 away from the motor. The connecting rod 405 passes through the inner cylinder 402, extends to the outer cylinder 401, and is fixedly connected to the outer cylinder 401.
[0026] When the dewatering machine is running, the motor drives the shaft 404 to rotate, which in turn drives the bottom plate 403 and the connecting rod 405 to rotate synchronously. The bottom plate 403 drives the outer cylinder 401 and the inner cylinder 402 to rotate. During the dewatering process of coal blocks, most of the coal blocks collide with the inner cylinder 402 during the rolling dewatering process, resulting in some coal sludge falling off. The coal sludge passes through the outer cylinder 401 and falls onto the surface of the inner cylinder 402. As the dewatering machine continues to run, the coal sludge continuously adheres to the surface of the outer cylinder 401. When the outer cylinder 401 rotates, it makes contact and friction with the circular brush 703 and the scraper 701, thereby removing the coal sludge adhering to the surface of the outer cylinder 401. This ensures that blockages are avoided when the dewatering machine rotates at high speed, thus improving the working efficiency of the dewatering machine.
[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The main body 10 of the dehydrator is provided with two symmetrical foot column assemblies 20. Each foot column assembly 20 includes a telescopic column 205. The telescopic column 205 is fixedly connected to the main body 10 of the dehydrator. A limit plate 201 is fixedly connected to the outside of the telescopic column 205. A support column 203 is movably sleeved on the end of the telescopic column 205 away from the main body 10 of the dehydrator. The support column 203 is hollow. A baffle 204 is fixedly connected to the side of the support column 203 near the limit plate 201. An annular spring piece 202 is fixedly connected to the side of the limit plate 201 and the baffle 204 facing each other. The annular spring piece 202 is made of elastic metal and is in the shape of an annular strip. The palm plate assembly 30 includes two symmetrical trays 301. One of the trays 301 near the support column 203 is fixedly connected to the support column 203. A damping rod 303 is fixedly connected between the two trays 301. At the same time, several airbag rods 302 are also fixedly connected between the two trays 301.
[0028] Each palm plate assembly 30 is externally provided with three fixing components 60. Each fixing component 60 includes a nail sleeve 602. The nail sleeve 602 is fixedly connected to the outside of the tray 301 at the end away from the support column 203. A ground nail 601 is provided on the outside of the nail sleeve 602. The ground nail 601 moves through the nail sleeve 602 and extends downward outside the nail sleeve 602. The ground nail 601 moves through the nail sleeve 602. Two elastic rods 603 are fixedly connected to the side of the nail sleeve 602 near the dehydrator body 10. One end of each elastic rod 603 is fixedly connected to the nail sleeve 602, and the other end of each elastic rod 603 is fixedly connected to the tray 301.
[0029] A support column assembly 50 is provided between the symmetrical support column assemblies 20. The support column assembly 50 includes a core column 501. One end of the core column 501 is fixedly connected to the outer wall of the dewatering machine body 10, and the other end of the core column 501 is fixedly connected to a load-bearing plate 503. Three shock-absorbing rings 502 are movably connected to the outside of the core column 501. The shock-absorbing rings 502 are made of rubber and are hollow inside.
[0030] When the dewatering machine is running at full load, the main body 10 of the dewatering machine shakes up and down, which in turn pushes the core column 501 to move the shock-absorbing ring 502 away from the main body 10. During the movement of the shock-absorbing ring 502, it contacts the load-bearing plate 503 and is compressed, thereby absorbing the thrust generated by the main body 10 of the dewatering machine and improving the stability of the dewatering machine. When the main body 10 of the dewatering machine shakes left and right, the main body 10 of the dewatering machine pushes the support column 203 to move the limiting plate 201 away from the main body 10 of the dewatering machine. The limiting plate 201 pushes the annular spring 202 away from the dewatering machine. The main body 10 moves in a direction and generates compression, while simultaneously pushing the tray 301 to move away from the main body 10 of the dehydrator. The tray 301 pushes the damping rod 303 and the airbag rod 302, while pulling the elastic rod 603 to move away from the main body 10 of the dehydrator. This buffers the thrust of the dehydrator main body 10 due to inertia during operation, improving the stability of the dehydrator main body 10 during operation. Technicians can also step on the ground nail 601 to move it closer to the nail sleeve 602, allowing it to penetrate the road surface, further stabilizing the dehydrator main body 10 and ensuring that it does not move during operation.
[0031] Working principle:
[0032] In the first step, when technicians use the dewatering machine to dewater the coal, the motor drives the shaft 404 to rotate. The shaft 404 drives the bottom plate 403 and the connecting rod 405 to rotate synchronously. The bottom plate 403 drives the outer cylinder 401 and the inner cylinder 402 to rotate. When the outer cylinder 401 rotates, it makes contact friction with the circular brush 703 and the scraper 701 respectively, thereby ensuring the stability inside the cylinder when the dewatering machine rotates at high speed, and at the same time avoiding the situation of partial coal melting and blockage, thus improving the stability of the internal operation of the dewatering machine.
[0033] In the second step, when the dewatering machine dewaters large coal blocks, the main body 10 of the dewatering machine sways up and down, which in turn pushes the core column 501 to move the shock-absorbing ring 502 away from the main body 10. During the movement of the shock-absorbing ring 502, it contacts the load-bearing plate 503 and is compressed, thereby absorbing the thrust generated by the main body 10 of the dewatering machine and improving the stability of the operation of the main body 10. When the main body 10 of the dewatering machine sways left and right, the main body 10 of the dewatering machine swayes left and right, which pushes the support column 203 to move the limiting plate 201 away from the main body 10 of the dewatering machine. The limiting plate 201 pushes the annular spring 202 away from the main body 10 of the dewatering machine. This generates compression, simultaneously pushing the tray 301 away from the main body 10 of the dewatering machine. The tray 301 pushes the damping rod 303 and the airbag rod 302, while pulling the elastic rod 603 away from the main body 10 of the dewatering machine. This buffers the thrust of the main body 10 of the dewatering machine due to inertia during operation, improving the stability of the main body 10 of the dewatering machine during operation. Technicians can also step on the ground nail 601 to move it closer to the nail sleeve 602, allowing it to penetrate the road surface, further stabilizing the main body 10 of the dewatering machine, ensuring that it does not move during operation, improving the stability of the dewatering machine during operation, and increasing the safety of the dewatering process.
[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
