Description

Technical Field

[0001] This utility model relates to the field of refractory material crushing and grinding technology, specifically to a refractory material crushing and grinding equipment. Background Technology

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. They possess excellent properties such as high temperature resistance, corrosion resistance, and heat insulation. Refractory materials play a vital role and are widely used in high-temperature industrial fields such as metallurgy, building materials, power, and chemicals. In blast furnaces and converters in the metallurgical industry, refractory materials can withstand the erosion of high-temperature molten iron and slag, protecting the furnace structure. In cement kilns, they can resist the scouring and chemical erosion of high-temperature materials, ensuring the normal operation of the kiln. In glass kilns, they can maintain a high-temperature environment, ensuring high-quality glass production. Because refractory materials usually need to be processed into specific particle sizes and shapes before use to meet the requirements of different industrial kilns, refractory material crushing and grinding equipment is required.

[0003] Existing refractory material crushing and grinding equipment involves feeding raw materials into the equipment through the feed inlet. The crushing rollers first crush the raw materials, and some of the crushed raw materials are screened through the screen. The raw materials that do not pass through the screen will roll on the upper surface of the screen to the grinding rollers for further grinding, so that the refractory raw materials reach the required particle size.

[0004] Existing refractory crushing and grinding equipment uses stationary screens. When crushing large quantities of refractory materials, the material accumulates on the screen surface, which not only reduces screening efficiency but may also cause screen blockage, preventing materials from passing through the screen normally. This affects the continuity of the entire production process and requires frequent shutdowns to clean the screen, thus reducing the efficiency of refractory material crushing and grinding. Therefore, we propose a new refractory material crushing and grinding equipment. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a refractory material crushing and grinding equipment that helps the material to be evenly distributed on the screen surface and smoothly conveyed to the grinding roller, avoids the poor conveying caused by the local accumulation of material on the screen, and ensures the smooth operation of the entire crushing and grinding process. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a refractory material crushing and grinding equipment, comprising a box body, a baffle plate provided in the middle between the front and rear inner walls of the box body, crushing rollers rotatably connected to the left side between the front and rear inner walls of the box body, and grinding rollers rotatably connected to the right side between the front and rear inner walls of the box body, and further comprising a screening mechanism;

[0007] Screening mechanism: It includes support blocks, telescopic rods, springs, and screen plates. Support blocks are provided on the front and rear inner walls of the housing. Telescopic rods are fixedly connected to the upper surface of the support blocks. The telescopic ends of the four telescopic rods are fixedly connected to the bottom end of a screen plate.

A rectangular groove is opened in the middle of the baffle. The outside of the screen plate is slidably connected to the inner wall of the rectangular groove, which helps the material to be evenly distributed on the screen surface and smoothly conveyed to the grinding rollers. This avoids the poor conveying caused by the local accumulation of material on the screen and ensures the smooth operation of the entire crushing and grinding process.

[0008] Furthermore, a microcontroller is provided on the left side of the enclosure. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the screening mechanism also includes a rotating column, a rotating rod, a sliding column, a support rod, and a T-shaped rod. The rotating column is rotatably connected to the right side of the baffle. A rotating rod is fixedly sleeved on the outside of the rotating column. A sliding column is provided on the right side of the rotating rod. A support rod is fixedly connected to the right side of the baffle. A T-shaped rod is slidably connected to the inside of the right end of the support rod. A sliding groove is opened at the upper end of the T-shaped rod. The outside of the sliding column is slidably connected to the inner wall of the sliding groove, so as to realize the up and down movement of the screen plate.

[0010] Furthermore, a worm gear is fixedly sleeved on the outside of the rotating column, and a worm is rotatably connected to the top wall of the housing. The worm gear and the worm are meshed together. A dustproof shell is provided on the right side of the baffle, and the meshing point between the worm gear and the worm is located inside the dustproof shell, ensuring stable rotation of the rotating column.

[0011] Furthermore, a motor is provided on the upper surface of the housing. The bottom end of the output shaft of the motor is fixedly connected to the top end of the worm gear, and the input end of the motor is electrically connected to the output end of the microcontroller to provide vibration drive for the screen.

[0012] Furthermore, gears are fixedly fitted on the outer rear ends of the crushing roller and the grinding roller respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This refractory material crushing and grinding equipment has the following advantages:

[0015] The motor drives the worm gear to rotate, which in turn drives the rotating column to rotate. The rotating column drives the sliding column to slide inside the groove of the T-shaped rod. The T-shaped rod slides inside the groove under the support of the support rod. The bottom end of the T-shaped rod contacts the screen plate and presses down on the screen plate, causing the spring to contract. The bottom end of the T-shaped rod moves away from the upper surface of the screen plate. Under the rebound of the spring, the screen plate slides inside the rectangular groove, realizing the vibration of the screen plate. This allows the crushed refractory material to pass through the screen quickly, reducing the possibility of screen hole blockage, ensuring the screen's permeability, reducing the frequency of downtime for cleaning due to screen blockage, improving the production efficiency of the refractory crushing and grinding equipment, and ensuring the uniformity of the crushed and ground refractory material.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a refractory material crushing and grinding equipment, including a housing 1, a baffle 2 provided in the middle between the front and rear inner walls of the housing 1, a crushing roller 3 rotatably connected between the left side of the front and rear inner walls of the housing 1, and a grinding roller 4 rotatably connected between the right side of the front and rear inner walls of the housing 1, and also includes a screening mechanism 6. A single-chip microcomputer 16 is provided on the left side of the housing 1, and the input end of the single-chip microcomputer 16 is electrically connected to an external power source.

The front end of the output shaft of the second motor 15 is fixedly connected to the rear end of the crushing roller 3 on the left. The input end of the second motor 15 is electrically connected to the output end of the microcontroller 16. When the refractory material needs to be crushed and ground, the box 1 is first moved to the designated position. Then, through the control of the microcontroller 16, the second motor 15 starts to run. The output shaft will drive the crushing roller 3 on the left to start running. Under the meshing action of the gear 11, the crushing roller 3 on the right will rotate synchronously. Then, the pulley 12 will start to rotate. Under the transmission action of the belt, the pulley 13 will drive the grinding roller 4 on the left to start rotating. Under the meshing action of the gear 11, the grinding roller 4 on the right will also start to rotate. Then, the crushing roller 3 and the grinding roller 4 will rotate synchronously inside the box 1. The refractory material is put into the box from the feed hopper at the top of the box 1. The crushing roller 3 crushes the refractory material first.

[0023] Screening mechanism 6 includes support blocks 61, telescopic rods 62, springs 63, and screen plates 64. Support blocks 61 are respectively provided on the front and rear inner walls of the housing 1. Telescopic rods 62 are fixedly connected to the upper surfaces of the support blocks 61. The telescopic ends of the four telescopic rods 62 are fixedly connected to the bottom end of a screen plate 64. Springs 63 are movably sleeved on the outside of the telescopic rods 62, and are located between the lower surface of the screen plate 64 and the upper surface of the support blocks 61. A rectangular groove 5 is provided in the middle of the baffle 2, and the outside of the screen plate 64 is slidably connected to the inner wall of the rectangular groove 5. Screening mechanism 6 also includes a rotating column 65, a rotating rod 66, a sliding column 67, a support rod 68, and a T-shaped component. A rotating rod 69 is rotatably connected to the right side of the baffle 2. A rotating rod 66 is fixedly sleeved on the outside of the rotating rod 65. A sliding rod 67 is provided on the right side of the rotating rod 66. A support rod 68 is fixedly connected to the right side of the baffle 2. A T-shaped rod 69 is slidably connected to the inside of the right end of the support rod 68. A sliding groove is opened at the upper end of the T-shaped rod 69. The outside of the sliding rod 67 is slidably connected to the inner wall of the sliding groove. A worm gear 7 is fixedly sleeved on the outside of the rotating rod 65. A worm 8 is rotatably connected to the top wall of the housing 1. The worm gear 7 and the worm 8 are meshed. A dustproof shell 9 is provided on the right side of the baffle 2. The meshing point of the worm gear 7 and the worm 8 is located inside the dustproof shell 9. The upper surface is equipped with a motor 10. The bottom end of the output shaft of the motor 10 is fixedly connected to the top end of the worm gear 8. The input end of the motor 10 is electrically connected to the output end of the microcontroller 16. The crushed refractory material falls onto the upper surface of the screen plate 64. When the crushed refractory material particles are smaller than the mesh size of the screen plate 64, they will automatically fall to the discharge port and be discharged. Refractory material particles that fail to pass through the screen plate 64 will be guided by its incline and fall between the two grinding rollers 4 for further grinding before being discharged through the discharge port. When crushing and grinding large quantities of refractory material, in order to prevent a large amount of crushed material from falling onto the screen plate 64 and causing blockage, the microcontroller 16... When the control motor 10 starts running, the output shaft will drive the worm gear 8 to start rotating. Under the drive of the meshing worm wheel 7, the rotating column 65 will start rotating. Through the rotating rod 66, the sliding column 67 will slide inside the sliding groove of the T-shaped rod 69. Then, the T-shaped rod 69 will slide inside it under the support of the support rod 68. When the bottom end of the T-shaped rod 69 contacts the screen plate 64, it will press down on the screen plate 64 and cause the spring 63 to contract. When the bottom end of the T-shaped rod 69 moves away from the upper surface of the screen plate 64, the screen plate 64 will slide inside the rectangular groove 5 under the rebound action of the spring 63, causing the screen plate 64 to vibrate continuously, and the refractory material at the top will continuously roll on its surface.

[0024] The working principle of the refractory material crushing and grinding equipment provided by this utility model is as follows: When refractory materials need to be crushed and ground, the box 1 is first moved to the designated position. Then, through the control of the single-chip microcomputer 16, the motor 15 starts to run, and the output shaft drives the left crushing roller 3 to start running. Under the meshing action of the gear 11, the right crushing roller 3 rotates synchronously, which in turn causes the pulley 12 to start rotating. Under the transmission action of the belt, the pulley 13 drives the left grinding roller 4 to start rotating. Under the meshing action of the gear 11, the right grinding roller 4 also starts to rotate, thus causing the crushing roller 3 and the grinding roller 4 to rotate synchronously inside the box 1. The refractory material is fed into the box 1 from the feed hopper at the top of the box 1. The crushing roller 3 first crushes the refractory material. The crushed refractory material falls onto the upper surface of the screen plate 64. When the crushed refractory material particles are smaller than the mesh of the screen plate 64, they will automatically fall into the discharge port and be discharged. Refractory material particles that fail to pass through the screen plate 64 will be guided by the inclined direction and fall between the two grinding rollers 4 for further grinding before being discharged through the outlet. When crushing and grinding large quantities of refractory materials, in order to prevent a large amount of crushed material from falling onto the screen plate 64 and causing blockage, the microcontroller 16 controls the motor 10 to start running. The output shaft will drive the worm gear 8 to start rotating. Under the drive of the meshing worm wheel 7, the rotating column 65 will start rotating. Through the rotating rod 66, the sliding column 67 will slide inside the groove of the T-shaped rod 69, and then the T-shaped rod 69 will slide inside it under the support of the support rod 68. When the bottom end of the T-shaped rod 69 contacts the screen plate 64, it presses down on the screen plate 64 and causes the spring 63 to contract. When the bottom end of the T-shaped rod 69 moves away from the upper surface of the screen plate 64, the screen plate 64 will slide inside the rectangular groove 5 under the rebound action of the spring 63, causing the screen plate 64 to vibrate continuously, and the refractory material at the top will continuously roll on its surface.

[0025] It is worth noting that the microcontroller 16 disclosed in the above embodiments can be LPC1768, motor 10 can be YS8024, and motor 2 can be Y180L-615. The microcontroller 16 controls the operation of motor 10 and motor 2 15 using methods commonly used in the prior art.
