A coke block grinding device

Abstract

This application provides a coke block grinding device, relating to the field of coke grinding, including a machine body. To address the problems in existing coke block grinding devices where, during operation, the coke thrown up by the shovel is difficult to retain in the gap between the grinding roller and grinding ring, resulting in insufficient feed between the roller and ring, and a small amount of material per grinding cycle, leading to low overall grinding efficiency, this application addresses these issues by incorporating a synchronous adjustment mechanism. This mechanism locally obstructs the grinding area and accelerates the rate at which coarse coke powder falls back into the grinding area, extending the grinding time and increasing the amount of coke ground per cycle, thereby improving overall grinding efficiency. Furthermore, the synchronous adjustment mechanism solves the problems of low sorting efficiency due to high sorting loads in existing technologies; low grinding uniformity due to powder accumulation on the inner wall of the machine body; and short equipment lifespan due to increased grinding load caused by agglomerated materials.

Description

[0001] This invention relates to the field of coke grinding, and more specifically, to a grinding apparatus for coke blocks. Background Technology

[0002] In the metallurgical and carbon industries, it is often necessary to grind lumpy coke into standard coke powder for use in processes such as blast furnace injection, raw material proportioning, and fuel combustion. Existing technology uses a coke lump grinding device to grind the coke. Currently, the industry mostly uses pendulum mills to complete the processing. The equipment is powered by an energy-saving electric motor, which drives the grinding rollers and grinding rings to crush the coke. The powder is then conveyed upward by a blower, and the coarse and fine powders are separated by a sorting mechanism to stably produce qualified coke powder. The overall structure is compact and energy-saving in operation.

[0003] Existing coke block grinding devices consist of a frame, grinding roller mechanism, shovel mechanism, air supply mechanism, and sorting mechanism. The coke is thrown up by the shovel and then crushed by the grinding roller and grinding ring to achieve coke grinding. However, in actual use, the coke thrown up by the shovel is difficult to stay on the inner wall of the grinding ring for a long time, and the amount of coke entering between the grinding ring and the grinding roller is small, resulting in a small amount of coke being ground in a single operation and low grinding efficiency.

[0004] Therefore, this application makes an improvement by proposing a grinding device for coke blocks. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing coke grinding devices, during operation, have difficulty retaining the coke thrown up by the shovel in the gap between the grinding roller and the grinding ring, resulting in insufficient feed between the roller and the ring, and a small amount of material per grinding cycle, leading to low overall grinding efficiency.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] As described in the background art, when the coke block grinding device is in operation, the coke thrown up by the shovel is difficult to retain in the gap between the grinding roller and the grinding ring, the feed between the roller and the ring is insufficient, the amount of material ground in a single cycle is too small, resulting in low overall grinding efficiency.

[0022] To solve this technical problem, the present invention provides a grinding device for coke blocks, which is applied to coke grinding.

[0023] For details, please refer to Figure 1 - Figure 9 As shown, the grinding device for the coke blocks specifically includes: a machine body 1, an air supply mechanism 101, a shovel mechanism 102 and a sorting mechanism 103 installed on the machine body 1, a feed inlet 104 installed on the machine body 1, and a synchronous adjustment mechanism 2 installed inside the machine body 1. In the prior art, the air supply mechanism 101 is used to transport airflow and coke. The coarse coke powder and fine coke powder are driven into the sorting mechanism 103 by direct airflow. The air supply mechanism 101 is connected to the existing blower and its wind speed is adjustable. The shovel mechanism 102 is used to drive the shovel to rotate and shovel up the bottom coke. The coke is thrown into the gap between the grinding roller 204 and the grinding ring 205 to complete the crushing and grinding. The sorting mechanism 103 is used to screen the particle size. The qualified fine powder is sent out, and the coarse material falls back for grinding again. The synchronous adjustment mechanism 2 includes a drive shaft 201 rotatably mounted on the machine body 1, a mounting bracket 202 mounted on the drive shaft 201, a fixed column 203 mounted on the mounting bracket 202, a grinding roller 204 rotatably mounted on the fixed column 203, a grinding ring 205 mounted on the grinding roller 204, a transmission ring 206 rotatably mounted on the mounting bracket 202 and the drive shaft 201, a blocking block 207 mounted on the transmission ring 206, an inclined groove 208 mounted on the blocking block 207, an arc plate 209 mounted on the machine body 1, and a drive assembly 3 mounted on the mounting bracket 202.

[0024] The coke block grinding device provided by this invention addresses the problem in the prior art where, during operation, the coke thrown up by the shovel is difficult to retain in the gap between the grinding roller 204 and the grinding ring 205, resulting in insufficient feed between the roller and ring, and a small amount of material per grinding cycle, leading to low overall grinding efficiency. This application improves the overall grinding efficiency by setting a synchronous adjustment mechanism 2, which locally blocks the grinding area and accelerates the rate at which coarse coke powder falls back into the grinding area. By using the synchronous adjustment mechanism 2, the arc plate 209 is driven to pre-screen the coarse and fine coke powder, which reduces the workload of the sorting mechanism 103, improves the overall sorting efficiency, and solves the problem of low sorting efficiency caused by high sorting load in the prior art. By using the synchronous adjustment mechanism 2, the machine body 1 is intermittently vibrated to break up the coke powder adhering to the inner wall of the machine body 1, remove the powder accumulation on the inner wall, avoid local powder accumulation leading to uneven grinding, improve the uniformity of grinding, and solve the problem of low uniformity of grinding caused by powder accumulation on the inner wall of the machine body 1 in the prior art. By using the synchronous adjustment mechanism 2, the arc plate 209 is driven to pre-disperse the agglomerated coke powder, thereby reducing the grinding load caused by the agglomerated coke powder, reducing equipment wear, and improving the service life of the equipment. This solves the problem in the prior art where the increased grinding load due to agglomerated materials leads to a shorter service life of the equipment.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a grinding device for coke blocks has a grinding roller 204 and a grinding ring 205 that are adapted to each other, a blocking block 207 that is slidably disposed on a mounting frame 202, and an inclined groove 208 and an arc plate 209 that are adapted to each other. In use, the scraper mechanism 102 throws coke into the gap between the grinding roller 204 and the grinding ring 205. In the prior art, the machine body 1 is used to drive the drive shaft 201 to rotate. The rotation of the drive shaft 201 drives the mounting frame 202, the fixed column 203, and the grinding roller 204 to rotate synchronously. The rotating grinding roller 204 slides along the grinding ring 205 and grinds the coke. The ground coke powder is conveyed upward along the machine body 1 by the air supply mechanism 101. Figure 3 As shown, the blocking block 207 and the mounting bracket 202 partially obstruct the coke being ground, thereby slowing down the rising speed of the coke and prolonging the time the coke remains in the grinding area. The direct current airflow drives the coke powder to be discharged from the inclined trough 208. The inclined trough 208 is designed to be inclined, and through the guidance of the inclined trough 208, the discharged coke powder, both coarse and fine, impacts the arc-shaped plate 209. The coarse coke powder, due to its large mass and strong inertia, falls directly back into the grinding area after impact, while the fine coke powder, being lighter, rebounds and floats upward, accelerating the secondary grinding of the coarse coke powder. This is achieved by partially obstructing the grinding area and accelerating the rate at which the coarse coke powder falls back into the grinding area. The grinding time and single grinding volume of coke are extended, improving the overall grinding efficiency. The coarse and fine coke powders are pre-screened by the arc plate 209, reducing the workload of the sorting mechanism 103 and improving the overall sorting efficiency. The drive component 3 drives the transmission ring 206 to rotate, which in turn drives the blocking block 207 and the inclined trough 208 to rotate synchronously. The rotation of the inclined trough 208 blocks the mounting frame 202. According to the grinding requirements of coke, the discharge volume of coke powder in the inclined trough 208 is adjusted in this way, thereby adjusting the coke residence time in the grinding process and improving the practicality of the equipment. Furthermore, the drive assembly 3 includes a motor 301 mounted on the mounting bracket 202, a synchronous shaft 302 mounted on the output end of the motor 301, a gear 303 mounted on the synchronous shaft 302, and a gear ring 304 mounted on the transmission ring 206. The motor 301 is started, which drives the synchronous shaft 302 to rotate. The synchronous shaft 302 rotates and drives the gear 303 to rotate. The gear 303 rotates and drives the gear ring 304 to rotate. The gear ring 304 rotates and drives the transmission ring 206 to rotate. The mounting bracket 202 is equipped with a battery to power the motor 301. Furthermore, the synchronous shaft 302 is rotatably mounted on the mounting bracket 202, and the gear 303 and the gear ring 304 are mutually adapted; Furthermore, the mounting bracket 202 is provided with an inclined block 217, the inclined block 217 and the inclined groove 208 are adapted to each other, and the fixing column 203 is provided on the inclined block 217. When the inclined groove 208 is blocked or needs to be cleaned, the blocking block 207 rotates and drives the inclined groove 208 and the inclined block 217 to engage. The inclined block 217 cleans the inner wall of the inclined groove 208, thus achieving self-cleaning of the inclined groove 208. Furthermore, the inclined block 217 is provided with a flat portion 218, and the flat portion 218 and the blocking block 207 are adapted to each other; The blocking block 207 is positioned and limited by the flat part 218. When the blocking block 207 rotates and blocks the mounting bracket 202, the blocking block 207 is quickly positioned by the contact between the flat part 218 and the blocking block 207. Furthermore, a limit ring 215 is provided on the transmission ring 206, and the limit ring 215 and the transmission ring 206 are connected by bolts 216. By rotating bolt 216, bolt 216 rotates and releases the limiting ring 215 from limiting the blocking block 207. By disengaging the limiting ring 215 from the transmission ring 206, the blocking block 207 and the transmission ring 206 can be separated, realizing the quick replacement and maintenance of the blocking block 207. By using the synchronous adjustment mechanism 2 to partially block the grinding area and accelerate the rate at which coarse coke falls back into the grinding area, the grinding time and the amount of coke ground in a single pass are extended, thus improving the overall grinding efficiency. The synchronous adjustment mechanism 2 also drives the arc plate 209 to pre-screen the coarse and fine coke powder, reducing the workload of the sorting mechanism 103 and improving the overall sorting efficiency.

[0029] Example 2 further optimizes the coke block grinding device provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the blocking block 207 is rotatably mounted on the transmission ring 206. The transmission ring 206 is provided with a sliding groove 210. A pushing block 211 is slidably mounted on the sliding groove 210. A spring 212 is provided on the corresponding surface of the pushing block 211 and the sliding groove 210. A semi-circular groove 213 is provided on the blocking block 207. Furthermore, the push block 211 is rotatably equipped with a ball bearing 214, which is adapted to the semi-circular groove 213. When the transmission ring 206 rotates, the ball bearing 214 and the push block 211 on the transmission ring 206 rotate synchronously. The ball bearing 214 presses against the semi-circular groove 213, causing the blocking block 207 to rotate synchronously. When the blocking block 207 rotates and fits against the flat surface 218, the limiting effect of the flat surface 218 prevents the blocking block 207 from rotating. At this time, the ball bearing 214 disengages from the semi-circular groove 213, and the ball bearing 214 and the push block slide along the sliding groove 210. The spring 212 is compressed. When the ball bearing 214 rotates and engages with the semi-circular groove 213, the elasticity of the spring 212 drives the ball bearing 214 and the push block to slide back to their original positions. The ball bearing 214 slides and impacts the semi-circular groove 213, thereby causing the blocking block 207 to vibrate. The vibration is controllable. By intermittently vibrating the machine body 1, the coke powder adhering to the inner wall of the machine body 1 is dispersed, the accumulated powder on the inner wall is removed, and the local accumulation of powder is avoided, which leads to uneven grinding and improves the uniformity of grinding. Furthermore, an annular groove 219 is provided on the body 1, an arc plate 209 is slidably disposed on the annular groove 219, a spring 220 is provided on the annular groove 219 and the annular plate, and a sealing part 221 is provided on the arc plate 209. When the coarse and fine coke powder discharged from the inclined chute 208 impacts the arc-shaped plate 209, the elasticity of the spring 220 buffers the arc-shaped plate 209, reducing wear and extending its service life. When the arc-shaped plate 209 slides and buffers, such as... Figure 2 As shown, there are two sets of arc plates 209. When a single set of arc plates 209 slides, the sealing parts 221 on both sides of the arc plate 209 slide synchronously. The sealing parts 221 seal the gap between the two sets of arc plates 209 to prevent coke powder from entering the annular groove 219, thereby preventing the arc plates 209 from getting stuck. When the coke powder clumps, the clumps collide with the arc plates 209, which pre-disperse the clumps, reducing the grinding load, reducing equipment wear, and improving the service life of the equipment. The synchronous adjustment mechanism 2 intermittently vibrates the machine body 1 to break up the coke powder adhering to the inner wall of the machine body 1, removes the powder accumulation on the inner wall, avoids local powder accumulation that leads to uneven grinding, and improves the uniformity of grinding. The synchronous adjustment mechanism 2 drives the arc plate 209 to pre-break up the agglomerated coke powder, reducing the agglomerated coke powder, increasing the grinding load, reducing equipment wear, and improving the service life of the equipment.

[0030] The process of using the coke block grinding device provided by this invention is as follows: During use, the scraper mechanism 102 throws coke into the gap between the grinding roller 204 and the grinding ring 205. In the prior art, the machine body 1 is used to drive the drive shaft 201 to rotate. The rotation of the drive shaft 201 drives the mounting frame 202, the fixed column 203, and the grinding roller 204 to rotate synchronously. The rotating grinding roller 204 slides along the grinding ring 205 and grinds the coke. The ground coke powder is conveyed upward along the machine body 1 by the air supply mechanism 101. The blocking block 207 and the mounting frame 202 partially block the coke being ground, thereby slowing down the upward speed of the coke and extending the grinding time. During the grinding period, the coke powder is driven by a direct current airflow to exit from the inclined trough 208. The inclined trough 208 is designed to be inclined, and the discharged coke powder, both coarse and fine, impacts the arc-shaped plate 209. The coarse coke powder, due to its large mass and strong inertia, falls directly back into the grinding area after impact, while the fine coke powder, being lighter, rebounds and floats upward. The motor 301 is then activated, driving the synchronous shaft 302 to rotate. The synchronous shaft 302 rotates, driving the gear 303 to rotate, which in turn drives the gear ring 304 to rotate. The gear ring 304 rotates, driving the transmission ring 206 to rotate. The ball bearing 214 and the pusher block 211 on the 06 rotate synchronously. The ball bearing 214 presses against the semi-circular groove 213, causing the blocking block 207 to rotate synchronously. When the blocking block 207 rotates and comes into contact with the flat surface 218, the limiting effect of the flat surface 218 prevents the blocking block 207 from rotating. At this time, the ball bearing 214 disengages from the semi-circular groove 213, and the ball bearing 214 and the pusher block slide along the sliding groove 210. The spring 212 is compressed. When the ball bearing 214 rotates and engages with the semi-circular groove 213, the elasticity of the spring 212 drives the ball bearing 214 and the pusher block to slide back to their original positions. 14. The semicircular groove 213 is slid and impacted, thereby causing the blocking block 207 to vibrate. The vibration is controllable. The intermittent vibration of the machine body 1 disperses the coke powder adhering to the inner wall of the machine body 1. The inclined groove 208 rotates and blocks the mounting frame 202. According to the grinding requirements of coke, the discharge amount of coke powder in the inclined groove 208 is adjusted in this way. When the inclined groove 208 is blocked or needs to be cleaned, the blocking block 207 rotates and drives the inclined groove 208 and the inclined block 217 to engage. The inclined block 217 cleans the inner wall of the inclined groove 208.
