Description

Technical Field

[0001] The invention relates to the technical field of coal chemical processing, and in particular to a coal chemical energy-saving grinding device and a grinding process. Background Art

[0002] In the gasification and liquefaction processes of coal chemical industry, the particle size of raw materials has a great influence on the reaction efficiency. After energy-saving grinding, the raw materials have smaller and more uniform particle sizes and larger specific surface areas. Taking coal gasification as an example, the contact area between fine particles of coal and gasification agents (such as oxygen and water vapor) increases, making the gasification reaction more complete and improving the conversion rate of coal, thereby improving the efficiency of the entire gasification process. By optimizing the grinding equipment and process parameters, the energy consumption in the grinding process is reduced.

[0003] Existing grinding equipment will generate pollutants such as dust and noise during the grinding process. For example, when a crusher is crushing coal, a large amount of coal dust will be generated. If this coal dust is not effectively collected and treated, it will be discharged into the air, causing harm to the environment and the health of operators. At the same time, the noise generated by the operation of the grinding equipment may exceed the environmental protection standard, causing noise pollution to the surrounding environment.

[0004] In the patent document with the publication number CN220610730U, a coal chemical experimental device is disclosed. The spiral patterns of the first screw rod and the second screw rod are opposite, and the meshing rotation of the transmission gear also causes the first screw rod and the second screw rod to rotate in opposite directions, so that the coal blocks are continuously squeezed toward the middle for grinding and crushing. Compared with the existing ordinary coal chemical experimental devices, the grinding efficiency and grinding performance are greatly improved, and the quality of coal block grinding is also improved.

[0005] When the above device is in use, the coal blocks rotate in opposite directions on the first spiral rod and the second spiral rod to increase the grinding efficiency of the coal chemical industry. Since the coal blocks are brittle after grinding and cannot immediately meet the specified requirements, the existing technology usually uses a screen to screen out the substandard coal blocks and then collects and processes them again. In this process, the overall efficiency is low, and the coal usually has a large amount of dust during the processing. When the staff take out the unqualified coal blocks, it is easy to cause the coal powder to spread, which is not conducive to the health of the staff.

[0006] Therefore, the present application proposes a coal chemical energy-saving grinding device and grinding process. Summary of the invention

[0017] On the other hand, the present application provides: a coal block grinding process, comprising the following steps: S1: Before grinding, the coal chemical raw materials are screened and large impurities and stones are removed through a vibrating screen, so that the particle size of the raw materials entering the grinding stage is set in a uniform state; S2: The pre-treated raw materials are coarsely ground using a jaw crusher, which crushes large pieces of raw materials into small particles by squeezing and crushing; S3: When the input cover block and the processing outer frame are in a tightly fitted state, the worker passes the coal block into the processing outer frame from the input slot on the top of the input cover block, and the first motor drives the two first gears to rotate, so that the coal stone processed between the auxiliary rotating rods is ground; S4: The auxiliary processing plate is driven to move up and down by the up and down swinging assembly.

[0018] In summary, the present application includes at least one of the following beneficial technical effects: 1. As the up and down swinging components drive the auxiliary processing plate to move up and down back and forth, when the auxiliary processing plate drives the screen fixing plate to move downward through the fixed support column, the coal stone particles originally placed horizontally roll along the rough surface of the auxiliary separation screen, causing the impurities adsorbed on the surface of the auxiliary separation screen to be shaken off. When the fixed support column drives the screen fixing plate to move upward, it is restored to a horizontal state due to the elastic force of the auxiliary spring set at the connection between the screen fixing plate and the auxiliary separation screen. The screen fixing plate and the auxiliary separation screen are close to the threaded processing leaves, and the unqualified coal stones continue to contact with the threaded processing leaves, thereby avoiding manual contact, and directly grinding the unqualified coal stones repeatedly, which improves the processing efficiency; 2. The first motor drives the thread processing blade to rotate back and forth in a small range, and the ball guide column slides along the second receiving groove. The compression cleaning block absorbs the residual material on the surface of the thread processing blade through the sponge characteristics. When the compression cleaning block returns to the receiving groove, the compressed compression cleaning block collects the residual material more tightly. When the input cover block is in the open state, the staff only needs to replace the compression cleaning block to better maintain the spiral blade, thereby improving the cleaning efficiency of the spiral blade and reducing the cleaning cost; 3. The other end of the swing link drives the supporting bottom block to move vertically up and down at the supporting limit of the positioning telescopic column. When the auxiliary processing plate moves up and down, the coal blocks inside it are broken up under the guidance of inertia due to their different textures, so that the coal blocks will not block the openings on both sides of the storage processing frame, making it easier for the suction component to collect the dust in the auxiliary processing plate, thereby reducing the generation of dust.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, a coal chemical energy-saving grinding device proposed by the present invention comprises a processing protection component 1, an up-and-down swing component 4 is installed at the bottom of the processing protection component 1, a thread processing roller 2 is installed inside the processing protection component 1, and a storage type processing component 3 is arranged in the middle of the processing protection component 1, and the storage type processing component 3 is fixedly installed on the top of the up-and-down swing component 4; The processing protection assembly 1 includes a processing outer frame 101, and an arc-shaped guide plate 107 is fixedly installed on the inner wall of the processing outer frame 101. Fig.10Compared with the processing area of ​​the traditional device, the arc guide plate 107 is a rectangular parallelepiped. The arc guide plate 107 is arc-shaped, so that the side wall spacing of the thread processing leaves 201 is equal, so that the processing area of ​​the coal block is equal, and because the gap in the processing area is reduced, the impact sound of the coal block flying on the arc guide plate 107 is smaller, thereby reducing some noise; Four first electric telescopic columns 104 are fixedly installed on the top of the processing outer frame 101, and an input cover block 102 is fixedly installed on one side of the first electric telescopic column 104 away from the processing outer frame 101. Figure 1 - Figure 2 The staff uses the four first electric telescopic columns 104 to lift the input cover block 102 to clean the inside of the processing outer frame 101 to avoid excessive accumulation of coal block residues and cause dust. At the same time, a slot hole for accommodating the first electric telescopic column 104 is opened at the bottom of the input cover block 102. When the first electric telescopic column 104 performs a compression movement, the input cover block 102 and the processing outer frame 101 are in a tightly fitted state. The staff passes the coal blocks from the input slot on the top of the input cover block 102 into the inside of the processing outer frame 101. Due to the closed state inside the input cover block 102, the coal ash generated during coal stone processing is reduced.

[0023] like Figure 1 - Figure 4 As shown, an auxiliary fixing block 105 is fixedly installed on one side of the processing outer frame 101, a first motor 106 is fixedly installed on the inner wall of the auxiliary fixing block 105, a first gear 103 is fixedly installed on the output end of the first motor 106, the number of the first gears 103 is two, and the two first gears 103 are arranged in a meshing state, the thread processing roller 2 includes an auxiliary rotating rod 202 fixedly installed inside the first gear 103, the auxiliary rotating rod 202 of the corresponding size is replaced according to the coarseness of the grinding, and the outer side of the auxiliary rotating rod 202 is fixedly installed with a thread processing leaf 201, as shown in FIG. Figure 3 A first gear 103 is driven to rotate by the first motor 106. Since the two first gears 103 are meshed with each other, the rotation directions of the two first gears 103 are opposite, so that the coal stone processed between the auxiliary rotating rods 202 can be fully ground.

[0024] like Figure 2 - Figure 8As shown, a plurality of compression cleaning blocks 204 are slidably installed on the outer side of the thread processing leaf 201 through a storage groove, and the compression cleaning blocks 204 are arranged in a circular state with respect to the surface of the thread processing leaf 201, and a second electric telescopic column 203 is fixedly installed inside the compression cleaning block 204, and a guide swivel 214 is fixedly installed on the side of the second electric telescopic column 203 away from the compression cleaning block 204, and an auxiliary guide ring 205 is rotatably installed on the outer side of the guide swivel 214, and the auxiliary guide ring 205 is fixedly installed on the inner wall of the processing outer frame 101, and a storage plug column 206 is rotatably installed on the inner wall of the processing outer frame 101, and the auxiliary rotating rod 202 is fixedly installed inside the storage plug column 206, and a first storage plug column 206 is provided on the outer side. The outer side of the receiving plug column 206 is rotatably installed with an arc-shaped guide hollow block 207, and the arc-shaped guide hollow block 207 is fixedly installed on the inner wall of the processing outer frame 101. A second receiving groove 213 is opened on the outer side of the arc-shaped guide hollow block 207. The second electric telescopic column 203 passes through the side of the compression cleaning block 204 and is fixedly installed with a guide plug-in ring 208. The inner wall of the guide plug-in ring 208 is hinged with a plurality of auxiliary hinged rods 209, and an arc spring 210 is fixedly installed between the auxiliary hinged rod 209 and the guide plug-in ring 208. A guide ball column 211 is fixedly installed on the side of the auxiliary hinged rod 209 away from the guide plug-in ring 208. When the guide ball column 211 connected to the auxiliary hinged rod 209 is in the first receiving groove 212, the compression cleaning The processing block 204 is located inside the thread processing leaf 201, and the arc spring 210 uses elastic force to fit the ball guide column 211 to the inner wall of the first receiving groove 212, then the auxiliary rotating rod 202 drives the second electric telescopic column 203 and the compression cleaning block 204 to rotate together to process the material, and when the processing is completed, the second electric telescopic column 203 drives the compression cleaning block 204 to slide out of the receiving groove of the thread processing leaf 201, at this time, the ball guide column 211 moves along the arc surface of the side of the first receiving groove 212 toward the arc-shaped guide hollow block 207, at this time, the auxiliary hinge rod 209 enters the second receiving groove 213 in a compressed state along the arc surface of the arc-shaped guide hollow block 207, and the guide plug-in ring 208 loses the auxiliary hinge rod 209 and the auxiliary rotating The clamping force between the rods 202 causes the guide plug-in ring 208 to no longer rotate with the auxiliary rotating rod 202 or produce a rotation difference. When the guide ball column 211 just enters the edge of the second receiving groove 213, the compression cleaning block 204 is a sponge-type cleaning component. The compression cleaning block 204 changes from a compressed state to a normal state. The compression cleaning block 204 first contacts the side wall of the nearest compression cleaning block 204, and the first motor 106 is a forward and reverse motor. The first motor 106 drives the thread processing leaf 201 to rotate back and forth in a small amplitude. At the same time, the guide ball column 211 continues to slide along the second receiving groove 213 to the other side. At this time, the compression cleaning block 204 can contact and clean the other side of the thread processing leaf 201, thereby improving the cleaning effect.Under the action of multiple compression cleaning blocks 204, the side wall of one side of the thread processing leaf 201 is cleaned by friction to prevent coal stone residues from remaining on the blade of the thread processing leaf 201. Since coal stone is sticky at high temperature, if there is still a large amount of residues on the blade of the thread processing leaf 201, the friction of continued processing in the later stage will easily interfere with the work of the thread processing leaf 201, resulting in a shortened service life of the thread processing leaf 201. The compression cleaning block 204 absorbs the residues through the sponge characteristics. When the compression cleaning block 204 returns to the storage groove, the compressed compression cleaning block 204 stores the residues more tightly. When the input cover block 102 is in the open state, the staff only needs to replace the compression cleaning block 204 to better maintain the spiral blade, thereby improving the cleaning efficiency of the spiral blade and reducing the cleaning cost.

[0025] like Figure 8 - Fig. 9 As shown, a fixed chassis 401 is fixedly installed at the bottom of the processing outer frame 101, a main gear 402 is rotatably installed on one side of the fixed chassis 401, a plurality of fixed long plates 403 are fixedly installed on one side of the fixed long plate 403, a second gear 404 is rotatably installed on one side of the fixed long plate 403, and the second gear 404 is arranged in a meshing state with the main gear 402, the second gear 404 passes through a side of the fixed long plate 403 and is fixedly installed with a swing link 405, a side of the swing link 405 away from the fixed chassis 401 is hinged with a supporting bottom block 406, the supporting bottom block 406 is fixedly installed at the bottom of the auxiliary processing plate 301, a positioning telescopic column 407 is fixedly installed between the fixed chassis 401 and the supporting bottom block 406, the positioning telescopic column 407 is an electric telescopic mechanism, which improves the supporting force of the supporting bottom block 406, one of the second gears 404 is connected to the second motor, when the second The motor drives the second gear 404 to rotate, and the second gear 404 drives the other second gears 404 to rotate through the main gear 402 by meshing with the main gear 402. The swing link 405 rotates synchronously according to the fixed long plate 403, and the swing link 405 can be bent. The swing link 405 is composed of two sections of hinged rods. The other end of the swing link 405 drives the supporting bottom block 406 to move vertically up and down at the support limit of the positioning telescopic column 407. The positioning telescopic column 407 cooperates with the four groups of swing links 405 to perform telescopic movement, so that the supporting bottom block 406 can move up and down stably and quickly. During the process of the auxiliary processing plate 301 going back and forth, the coal blocks inside it are broken up under the guidance of inertia due to their different weights, so that the coal blocks will not block the openings on both sides of the storage processing frame 302, so that the suction component can collect the dust in the auxiliary processing plate 301, thereby reducing the generation of dust.

[0026] In this embodiment, Fig.10As shown, the inner wall of the arc-shaped guide plate 107 is fitted with two rotating columns 307, and an auxiliary separation screen 303 is rotatably installed on the outer side of the rotating column 307. There are two auxiliary separation screens 303, and a screen fixing plate 304 is hinged between the two auxiliary separation screens 303. Two leak-proof screens 305 are fixedly installed at the connecting gap between the screen fixing plate 304 and the auxiliary separation screen 303. A fixed support column 306 is fixedly installed at the bottom of the screen fixing plate 304, and an auxiliary processing plate 301 is fixedly installed on the side of the fixed support column 306 away from the screen fixing plate 304. A storage processing frame 302 is fixedly installed between the auxiliary processing plate 301 and the auxiliary separation screen 303. As the up and down swinging component 4 drives the auxiliary processing plate 301 to move up and down back and forth, when the auxiliary processing plate 301 drives the screen fixing plate 304 to move downward through the fixed support column 306, the auxiliary separation screens 303 on both sides of the screen fixing plate 304 are rotated. As the column 307 is guided by the arc trajectory of the arc guide plate 107, it deflects, and the coal particles originally placed horizontally roll along the rough surface of the auxiliary separation screen 303, causing the impurities adsorbed on the surface of the auxiliary separation screen 303 to be shaken off, and during the rolling process, the coal can quickly pass through the adapted small holes into the auxiliary processing plate 301 for collection, preventing the coal from accumulating and getting stuck in the through hole and being unable to flow smoothly. When the fixed support column 306 drives the screen fixing plate 304 to move upward, due to the elastic force of the auxiliary spring provided at the connection between the screen fixing plate 304 and the auxiliary separation screen 303 and the rotating column 307 following the guidance of the surface of the arc guide plate 107, the screen fixing plate 304 and the auxiliary separation screen 303 are restored to a horizontal state, and the screen fixing plate 304 and the auxiliary separation screen 303 are close to the threaded processing leaf 201, and the unqualified coal continues to contact with the threaded processing leaf 201, thereby avoiding manual contact, and directly grinding the unqualified coal repeatedly, thereby improving the processing efficiency. One side of the storage processing frame 302 is in a hinged state and can be opened to facilitate the staff to collect coal stones. The storage processing frame 302 is provided with through holes on the surrounding side, and there is a small separation net on the through hole. The other end of the through hole is provided with a suction component, such as an air pump and other equipment. When the auxiliary processing plate 301 and the rotating column 307 are away from the thread processing leaf 201, the suction component is used to absorb the dust inside the storage processing frame 302 and the auxiliary processing plate 301 to prevent the auxiliary processing plate 301 from being too close to the thread processing roller 2, causing the airflow to cause dust to scatter in the processing area.

[0027] On the other hand, the present application provides: a coal block grinding process, comprising the following steps: S1: Before grinding, the coal chemical raw materials are screened and large impurities and stones are removed through a vibrating screen, so that the particle size of the raw materials entering the grinding stage is set in a uniform state; S2: The pre-treated raw materials are coarsely ground using a jaw crusher, which crushes large pieces of raw materials into small particles by squeezing and crushing; S3: When the input cover block 102 and the processing outer frame 101 are in a tightly fitting state, the worker passes the coal block into the processing outer frame 101 from the input slot on the top of the input cover block 102, and the two first gears 103 are driven to rotate by the first motor 106, so that the coal stone processed between the auxiliary rotating rods 202 is ground; S4: The auxiliary processing plate 301 is driven to move up and down by the up and down swinging assembly 4. When the auxiliary processing plate 301 drives the screen fixing plate 304 to move downward through the fixed support column 306, the horizontally placed coal stone particles roll along the rough surface of the auxiliary separation screen 303, so that the impurities adsorbed on the surface of the auxiliary separation screen 303 are shaken off. When the fixed support column 306 drives the screen fixing plate 304 to move upward, the screen fixing plate 304 and the auxiliary separation screen 303 are close to the thread processing leaf 201, and the unqualified coal stone continues to contact with the thread processing leaf 201 for further processing; S5: After the processing is completed, the first motor 106 drives the thread processing leaf 201 to rotate back and forth in a small range, the ball guide column 211 slides along the second receiving groove 213, and the compression cleaning block 204 contacts and cleans the side of the thread processing leaf 201 to remove the residual material on the blade surface of the thread processing leaf 201; S6: The ground products are graded and screened, and the products are divided into different particle size grades through sieves of different mesh sizes. Qualified fine particle products are collected for subsequent processes, and coarse particles are returned to the fine grinding equipment for re-grinding to ensure the consistency of product particle size. The ground products that meet the particle size requirements are collected in storage containers.
