Description

Technical Field

[0001] This utility model relates to the technical field of grinding equipment, and in particular to a grinding equipment for high-strength, corrosion-resistant refractory materials used in ultra-large coal gas purification devices. Background Technology

[0002] Gas purification devices are used in industrial production to remove impurities such as fly ash, tar, naphthalene, ammonia, and hydrogen sulfide from coal gas. These devices are typically made from specialized refractory materials. These specialized refractory materials are generally inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the temperature in Celsius at which a conical sample of a refractory material can resist high temperatures without softening or melting under no load. In the production of specialized refractory materials, it is usually necessary to finely grind the crushed raw materials into particles ranging from millimeters to micrometers. Therefore, the grinding process of raw materials is one of the key steps in ensuring that the refractory products have good performance. A refractory material grinding device, as disclosed in prior art publication CN213133380U, includes a main body with a conical groove in the center of its top. A U-shaped frame is mounted on the top of the main body, and a motor is mounted on the top of the U-shaped frame. A rotating shaft is mounted on the output shaft of the motor. A first grinding block, a second grinding block, and a third grinding block are sequentially mounted on the rotating shaft from top to bottom. The outer sides of the first, second, and third grinding blocks are all conical, and their tops are all convex. The gap between the outer side of the first grinding block and the inner wall of the groove is larger than the gap between the outer side of the second grinding block and the inner wall of the groove, and the gap between the outer side of the second grinding block and the inner wall of the groove is larger than the gap between the outer side of the third grinding block and the inner wall of the groove. A discharge channel is provided on one side of the bottom of the groove. However, this device lacks a screening mechanism, making it impossible to determine the processing status. It is only used for grinding for a short period of time, and even materials with suitable particle sizes are ground, resulting in ineffective grinding and increasing the burden on the grinding rollers. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a high-strength, corrosion-resistant refractory material grinding device for ultra-large gas purification devices that reduces grinding of materials with suitable particle size, avoids ineffective grinding, can fully grind materials, and is conducive to improving work efficiency.

[0004] This utility model discloses a high-strength, corrosion-resistant refractory material grinding device for ultra-large-scale coal gas purification equipment. It includes a grinding box, a feeding component, a grinding component, a screening component, and a reflux component. The grinding box has a grinding chamber on its upper side and a finished product chamber on its lower side, located below the grinding chamber. The feeding component is installed on the upper left side wall of the grinding box and communicates with the grinding chamber. The grinding component is installed inside the grinding chamber, and a screening component is mounted on it. A reflux component is installed on the right side of the grinding box and communicates with the grinding chamber. Crushed raw materials are fed into the feeding component. Powder meeting the requirements directly enters the finished product chamber, while other raw materials enter the grinding chamber. The grinding component grinds the raw materials. Sufficiently ground refractory material falls into the finished product chamber through the screening component, while insufficiently ground refractory material passes through the screening component and enters the reflux component, being re-input into the upper part of the grinding chamber until the refractory material is fully ground, thus improving grinding efficiency.

[0005] Preferably, the feeding component includes a feeding box, a hopper, a sorting screen, and multiple connecting pipes. The feeding box is installed on the left side wall of the grinding chamber, and the right side of the feeding box is connected to the grinding chamber. A hopper is installed at the top of the feeding box. The sorting screen is installed at an incline inside the feeding box. Multiple connecting pipes are evenly installed at the bottom of the feeding box, and the output end of the connecting pipes is connected to the finished product chamber. The crushed raw materials are added to the feeding box through the hopper. The powder that meets the requirements passes through the sorting screen and enters the finished product chamber directly through the connecting pipes. Other raw materials enter the grinding chamber for processing, reducing the grinding of materials with suitable particle size and avoiding ineffective grinding.

[0006] Preferably, the grinding components include a top plate, a geared motor, a main shaft, a first grinding block, a first sieve plate, a third grinding block, a conical platform, and a positioning seat. The top plate is installed at the top of the grinding box above the grinding chamber. The geared motor is installed on the top of the top plate, and the output end of the geared motor is equipped with the main shaft. The first grinding block, the second grinding block, and the third grinding block are mounted on the main shaft. The clearance between the first grinding block, the second grinding block, and the third grinding block and the inner wall of the grinding chamber decreases progressively. The conical platform is installed at the bottom of the grinding chamber, and a support groove is provided on the top of the conical platform. A positioning seat is installed at the bottom of the main shaft, and the positioning seat is rotatably mounted on the grinding chamber. Inside the support groove, a feeding trough communicating with the finished product chamber is opened at the bottom of the grinding groove. After the material enters the grinding chamber, the geared motor is started to drive the main shaft to rotate. The main shaft drives the first grinding block, the second grinding block and the third grinding block to rotate. The first grinding block performs initial grinding on the material, then the second grinding block performs secondary grinding, and finally the third grinding block performs finished product grinding. After multiple grinding, the grinding quality is ensured. The fully ground refractory material enters the finished product chamber for storage through the feeding trough. When the main shaft rotates, it drives the positioning seat to rotate in the support groove of the conical platform, which enhances the structural strength and ensures stability.

[0007] Preferably, the screening component includes a first screen plate and a second screen plate, both of which are mounted on the outer wall of the main shaft. The first screen plate is located between the first grinding block and the second grinding block, and the second screen plate is located between the second grinding block and the third grinding block. The mesh size of the first screen plate is larger than that of the second screen plate. The material ground by the first grinding block falls onto the first screen plate, while the material that is not sufficiently ground remains on the surface of the first screen plate. At the same time, the material ground by the second grinding block falls onto the second screen plate, while the material that is not sufficiently ground remains on the surface of the second screen plate. This process ensures that the material is thoroughly ground, which is beneficial for improving work efficiency.

[0008] Preferably, the reflux component includes a lifting shaft, a spiral conveyor blade, a reducer, and a drive motor. A reflux chamber is provided on the right side of the grinding box, and a reflux hole communicating with the grinding chamber is provided at the top of the reflux chamber. A first recovery hole and a second recovery hole communicating with the reflux chamber are provided inside the grinding chamber. The input end of the first recovery hole is located above the first screen plate, and the output end of the second recovery hole is located above the second screen plate. The lifting shaft is rotatably installed in the reflux chamber, and a spiral conveyor blade is installed on the outer wall of the lifting shaft. The reducer is installed at the top of the grinding box, and the input end of the lifting shaft is connected to the output end of the reducer, which is also connected to the output end of the drive motor. The material that is not fully ground on the upper surface of the first and second screen plates enters the reflux chamber through the first and second recovery holes, respectively. The drive motor is started, and the reducer drives the lifting shaft to rotate. The lifting shaft drives the spiral conveyor blade to rotate, conveying the incompletely ground material upward and re-inputting it into the grinding chamber through the reflux hole for processing, ensuring grinding quality.

[0009] Preferably, it also includes multiple support legs, multiple sets of triangular plates, and multiple base plates. The multiple support legs are respectively installed at the four corners of the bottom of the grinding box. Multiple triangular plates are installed between the upper part of the support legs and the bottom of the grinding box, and the base plates are installed at the bottom of the support legs. The bottom of the grinding box is supported by multiple support legs, and the triangular plates increase the connection strength between the support legs and the grinding box, ensuring the stability of the support.

[0010] Preferably, it also includes a controller and a discharge pipe. The controller is installed at the front end of the grinding box, and the discharge pipe is installed at the bottom of the grinding box and communicates with the finished product chamber. A solenoid valve is installed on the discharge pipe. The controller facilitates the control of the equipment and improves intelligence, while the discharge pipe facilitates the discharge of the processed material.

[0011] Preferably, lifting rings are symmetrically installed on the top of the top plate, and the top plate is bolted to the top of the grinding box; by loosening the bolts, the first grinding block, the second grinding block and the third grinding block can be easily removed from the grinding chamber by lifting equipment through the lifting rings, which can be replaced after long-term use and avoid the impact of wear on the grinding quality after long-term use.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: after the raw materials are crushed, they are fed into the feeding component. The powder that meets the requirements directly enters the finished product chamber, while other raw materials enter the grinding chamber. The raw materials are ground by the grinding component. The fully ground refractory material falls into the finished product chamber through the screening component, while the insufficiently ground refractory material enters the return component through the screening component and is reintroduced into the upper part of the grinding chamber until the refractory material is fully ground, thereby improving the grinding efficiency.

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0015] like Figures 1 to 5As shown, multiple support legs 22 are respectively installed at the four corners of the bottom of the grinding box 1. Multiple triangular plates 23 are installed between the upper part of the support legs 22 and the bottom of the grinding box 1. A base plate 24 is installed at the bottom of the support legs 22.

A discharge pipe 27 is installed at the bottom of the grinding box 1 and communicates with the finished product chamber. A solenoid valve is installed on the discharge pipe 27. A top plate 6 is installed above the grinding chamber. At the top of the housing 1, a geared motor 7 is mounted on the top plate 6. A main shaft 8 is mounted on the output end of the geared motor 7. A first grinding block 9, a second grinding block 11, and a third grinding block 13 are mounted on the main shaft 8. The clearance between the first grinding block 9, the second grinding block 11, and the third grinding block 13 and the inner wall of the grinding chamber gradually decreases. A conical platform 14 is mounted at the bottom of the grinding chamber. A support groove is provided at the top of the conical platform 14. A positioning seat 15 is mounted at the bottom of the main shaft 8 and is rotatably mounted within the support groove. A groove is provided at the bottom of the grinding groove to facilitate the grinding process. The material feeding trough is connected to the grinding chamber. A lifting ring 26 is symmetrically installed on the top of the top plate 6. The top plate 6 is bolted to the top of the grinding box 1. The first screen plate 10 and the second screen plate 12 are both installed on the outer wall of the main shaft 8. The first screen plate 10 is located between the first grinding block 9 and the second grinding block 11, and the second screen plate 12 is located between the second grinding block 11 and the third grinding block 13. The mesh size of the first screen plate 10 is larger than that of the second screen plate 12. A reflux chamber is opened on the right side of the grinding box 1, and a reflux hole communicating with the grinding chamber is opened at the top of the reflux chamber. The grinding chamber is provided with a first recovery hole 16 and a second recovery hole 17 that communicate with the return chamber. The input end of the first recovery hole 16 is located above the first sieve plate 10, and the output end of the second recovery hole 17 is located above the second sieve plate 12. The lifting shaft 18 is rotatably installed in the return chamber. The outer wall of the lifting shaft 18 is equipped with a spiral conveying blade 19.

The input end of the lifting shaft 18 is connected to the output end of the reducer 20, and the input end of the reducer 20 is connected to the output end of the drive motor 21. The crushed raw materials are fed into the feed box 2 through the feeding hopper 3. Powder meeting the requirements passes through the sorting screen plate 4 and directly enters the finished product chamber through the connecting pipe 5. Other raw materials enter the grinding chamber for processing, reducing grinding of materials with suitable particle size and avoiding ineffective grinding. After the material enters the grinding chamber, the reduction motor 7 is started to drive the main shaft 8 to rotate. The main shaft 8 drives the first grinding block 9, the second grinding block 11, and the third grinding block 13 to rotate. The first grinding block 9 performs initial grinding, then the second grinding block 11 performs secondary grinding, and finally the third grinding block 13 performs finished product grinding. Through multiple grinding processes, the grinding quality is ensured. The fully ground refractory material enters the finished product chamber for storage through the feeding chute. When the main shaft 8 rotates, it drives the positioning seat 15 to rotate within the support groove of the conical platform 14, enhancing structural strength and ensuring stability. The material ground by the first grinding block 9 falls onto the first screen plate 10, while the insufficiently ground material remains on the surface of the first screen plate 10. Simultaneously, the material ground by the second grinding block 11 falls onto the second screen plate 12, while the insufficiently ground material remains on the surface of the first screen plate 10.

Unground material from the upper surfaces of the first screen plate 10 and the second screen plate 12 enters the return chamber through the first recovery hole 16 and the second recovery hole 17, respectively. The drive motor 21, via the reducer 20, drives the lifting shaft 18 to rotate. The lifting shaft 18 then drives the spiral conveyor blades 19 to rotate, conveying the unground material upwards. The material is then reintroduced into the grinding chamber through the return hole for further processing, ensuring grinding quality. Multiple support legs 22 support the bottom of the grinding box 1, and triangular plates 23 increase the connection strength between the support legs 22 and the grinding box 1, ensuring stability. The controller 25 facilitates equipment control and enhances intelligence. The discharge pipe 27 allows for the discharge of processed material. Loosening the bolts and using the lifting ring 26, the first grinding block 9, the second grinding block 11, and the third grinding block 13 can be easily removed from the grinding chamber using lifting equipment, enabling replacement after prolonged use and preventing wear from affecting the grinding quality.

[0016] like Figures 1 to 5As shown, this utility model's ultra-large gas purification device uses a high-strength, corrosion-resistant refractory material grinding device. During operation, multiple support legs 22 support the bottom of the grinding chamber 1, and triangular plates 23 increase the connection strength between the support legs 22 and the grinding chamber 1. Crushed raw materials are added to the feed box 2 through the feeding hopper 3. Powder meeting the requirements passes through the sorting screen plate 4 and directly enters the finished product chamber through the connecting pipe 5. Other raw materials enter the grinding chamber. After the material enters the grinding chamber, the reduction motor 7 is started to drive the main shaft 8 to rotate. The main shaft 8 drives the first grinding block 9, the second grinding block 11, and the third grinding block 13 to rotate. The first grinding block 9 performs initial grinding, followed by secondary grinding by the second grinding block 11, and finally final grinding by the third grinding block 13. Through multiple grinding processes, the grinding quality is ensured. The fully ground refractory material enters the finished product chamber for storage through the feeding trough. The material ground by the first grinding block 9 falls onto the first screen plate 10, while the insufficiently ground material remains on the surface of the first screen plate 10. At the same time, the material ground by the second grinding block 11 falls onto the second screen plate 12, while the insufficiently ground material remains on the surface of the second screen plate 12. The incompletely ground material on the upper surfaces of the first screen plate 10 and the second screen plate 12 enters the return chamber through the first recovery hole 16 and the second recovery hole 17, respectively. The drive motor 21 is started, which drives the lifting shaft 18 to rotate through the reducer 20.
