Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate processing technology, specifically to a calcium carbonate processing and grinding device. Background Technology

[0002] Calcium carbonate is an important inorganic compound that is widely found in nature, mainly in minerals such as limestone, marble, and calcite. Its preparation methods are diverse, including calcining limestone, chemical precipitation, and grinding. The production and application of calcium carbonate are of great significance to the national economy. Grinding mills can process calcium carbonate ore or raw materials into fine or ultrafine powders. Grinding equipment for calcium carbonate is crucial for achieving fine processing of calcium carbonate and improving product performance and quality, and is widely used in various fields.

[0003] Patent CN218013011U discloses a calcium carbonate grinding device, belonging to the field of calcium carbonate processing technology. This calcium carbonate grinding device includes a grinding chamber; multiple support legs fixedly connected to the lower end of the grinding chamber; a first fixing plate fixedly connected to one side of the grinding chamber; a circular hole at the upper end of the grinding chamber; and a grinding mechanism, which includes a motor, a belt, two pulleys, two gears, two grinding rollers, two crushing rollers, and multiple connecting rods. When the motor is started, the crushing rollers rotate via the pulleys and belt, crushing the calcium carbonate. The crushed calcium carbonate falls onto the grinding rollers below, where it grinds the calcium carbonate. This solves the problem of not being able to ensure that the calcium carbonate is ground into fine particles during the grinding process, which directly affects product quality and reduces the practicality of the grinding machine.

[0004] Based on existing solutions and actual use, current calcium carbonate processing and grinding devices still have some problems, such as: when calcium carbonate enters through the feed port for grinding, the material may accumulate at the feed, causing blockage and affecting subsequent processing. At the same time, when grinding calcium carbonate, because different calcium carbonates have different particle size requirements, it is difficult to accurately control the particle size of the final product. Utility Model Content

[0005] The purpose of this utility model is to provide a processing and grinding device for calcium carbonate, so as to solve the problems mentioned in the background art, that calcium carbonate is prone to accumulate at the feed inlet during grinding, which leads to blockage and affects subsequent processing. At the same time, during the grinding of calcium carbonate, different calcium carbonates have different particle size requirements, making it difficult to control the particle size of the final product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a processing and grinding device for calcium carbonate, comprising:

[0007] The mounting frame has a grinding chamber fixedly mounted on its top, with the lower sidewall of the grinding chamber inclined. A feeding hopper is fixedly mounted on the top of the grinding chamber, and discharge ports are fixedly mounted on the left and right ends of the top of the grinding chamber. Sliding blocks are slidably connected to the left and right ends of the sidewall of the grinding chamber, and grinding rollers are mounted on the left and right ends inside the grinding chamber, with the grinding rollers rotatably connected to the sliding blocks. A motor is fixedly mounted on the rear sliding block of the grinding chamber, and the output end of the motor is fixedly connected to the rear shaft of the grinding roller. A sleeve block is rotatably connected to the outer side of the front shaft of the grinding roller. An adjustment assembly is provided on the front sidewall of the grinding chamber, and a separation assembly is provided on the frame of the mounting frame.

[0008] Preferably, the feed hopper and the discharge port are connected, and the side wall of the feed hopper is inclined, as is the side wall of the discharge port.

[0009] Preferably, the adjustment assembly includes a sliding rod, a spring, an adjustment block, and a limiting rod. The left and right ends of the front end of the grinding chamber are slidably connected to the sliding rod. One end of the sliding rod is fixedly connected to the sleeve block, and a spring is sleeved and connected to the outside of the sliding rod. The spring is fixedly connected to the sleeve block. An adjustment block is rotatably connected to the middle position of the front end of the grinding chamber, and a limiting rod is slidably connected to the upper end of the front end of the grinding chamber.

[0010] Preferably, the adjusting block is arranged in a semi-arc shape, and the adjusting block and the sliding rod are in a close fit. The adjusting block drives the grinding roller to slide in the opposite direction. The shaft of the adjusting block has a through hole, and the through hole on the adjusting block is arranged in a corresponding position to the limiting rod.

[0011] Preferably, the separation assembly includes a first mounting plate, a hinge frame, a screen, a guide rod, a second mounting plate, a push plate, and an electric push rod. The first mounting plate is slidably connected to both the left and right ends of the mounting frame. A hinge frame is fixedly mounted on the block of the first mounting plate, and a detachable screen is installed inside the hinge frame. The screen is positioned in a corresponding manner to the bottom of the grinding chamber. A guide rod is fixedly mounted to the bottom of the first mounting plate. The second mounting plate is fixedly mounted to both the left and right ends of the bottom of the mounting frame. A push plate is slidably connected to the top of the second mounting plate, and an electric push rod is fixedly mounted to the front end of the top of the second mounting plate.

[0012] Preferably, the output end of the electric push rod is fixedly connected to the push plate, the side wall of the push plate is inclined, and the push plate is in contact with the lower end of the guide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the calcium carbonate processing and grinding device can process more materials at the same time through the cooperation between the feed hopper and the discharge port, and reduce the clogging and stagnation time of the feed. Then, by adjusting the spacing between the grinding rollers, the particle size of calcium carbonate can be precisely controlled, and the best grinding effect can be ensured through appropriate spacing. At the same time, by the reciprocating up and down movement of the screen, particles of different sizes can be effectively separated, ensuring the purity and consistency of the final product.

[0014] 1. It is equipped with a grinding chamber, a feeding chamber, and a discharge port. The material is poured into the feeding chamber, which is set up with an inclined side wall. The feeding chamber is connected to the discharge port, which is also set up with an inclined side wall. The material is then diverted from the feeding chamber to the discharge port and then conveyed into the grinding chamber. The cooperation between the feeding chamber and the discharge port can process more material at the same time and reduce the clogging and stagnation time of the feeding, thereby improving work efficiency.

[0015] 2. The device is equipped with a sliding block, a grinding roller, a sleeve block, a sliding rod, a spring, an adjusting block, and a limiting rod. The grinding roller rotates on the sliding block, which slides against the side wall of the grinding chamber. By rotating the adjusting block, which is in a semi-circular shape, the adjusting block drives two sets of sliding rods to slide in opposite directions at the front end of the grinding chamber. This causes the sliding rods to stretch the spring. Since the sliding rods are fixedly connected to the sleeve block, and the sleeve block is rotatably connected to the front shaft of the grinding roller, rotating the adjusting block can move the grinding roller inside the grinding chamber via the sliding rod, thereby adjusting the distance between the left and right grinding rollers inside the grinding chamber. The limiting rod then fixes the adjusting block and the grinding chamber together, thus fixing the distance between the grinding rollers. By adjusting the distance between the grinding rollers, the particle size of calcium carbonate can be precisely controlled. At the same time, an appropriate distance can ensure the best grinding effect and ensure the consistent quality of each batch of products.

[0016] 3. The device is equipped with a mounting frame, a first mounting plate, a hinge frame, a screen, a guide rod, a second mounting plate, a push plate, and an electric push rod. The output end of the electric push rod drives the push plate to slide on the second mounting plate. The push plate is then set in an inclined state, and the push plate is in contact with the lower end of the guide rod. The electric push rod drives the push plate to slide back and forth, causing the push plate to drive the first mounting plate to slide up and down on the frame of the mounting frame. This, in turn, causes the hinge frame to move the screen up and down, thereby separating the material. The reciprocating up and down movement of the screen can effectively separate particles of different sizes, ensuring the purity and consistency of the final product. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-8 This utility model provides a technical solution: a processing and grinding device for calcium carbonate, comprising: a mounting frame 1, a grinding chamber 2, a feeding chamber 3, a feeding port 4, a sliding block 5, a grinding roller 6, a motor 7, a sleeve block 8, a sliding rod 9, a spring 10, an adjusting block 11, a limiting rod 12, a first mounting plate 13, a hinge frame 14, a screen 15, a guide rod 16, a second mounting plate 17, a push plate 18, and an electric push rod 19.

[0028] First, as attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, when grinding calcium carbonate, the distance between the grinding rollers 6 at both ends of the grinding chamber 2 is first adjusted according to the grinding requirements. Since sliding blocks 5 are slidably connected to both ends of the sidewalls of the grinding chamber 2, and the sliding blocks 5 are rotatably connected to the grinding rollers 6, a sleeve block 8 is sleeved and connected to the outer side of the front shaft of the grinding rollers 6. Sliding rods 9 are slidably connected to both ends of the front end of the grinding chamber 2, and the sliding rods 9 are fixedly connected to the sleeve block 8. An adjusting block 11 is also rotatably connected to the middle position of the front end of the grinding chamber 2, and the adjusting block 11 is set in a semi-arc shape. Because the adjusting block 11 is in a fitted state with the sliding rods 9, rotating the adjusting block 11 can drive the two sets of sliding rods 9 to... Sliding in opposite directions causes the spring 10 on the outside of the sliding rod 9 to stretch, and the sliding rod 9 drives the sliding block 5 to slide on the side wall of the grinding chamber 2 through the sleeve block 8. At the same time, the two sets of grinding rollers 6 move in opposite directions, thereby adjusting the distance between the two sets of grinding rollers 6. After the distance between the grinding rollers 6 is adjusted, the limiting rod 12 is slidably connected to the front end of the grinding chamber 2, and the limiting rod 12 is set in a corresponding state with the through hole on the shaft of the adjusting block 11. The limiting rod 12 can be inserted into the through hole on the rod of the adjusting block 11, thereby fixing the adjusting block 11 and the grinding chamber 2 together. By adjusting the distance between the grinding rollers 6, the particle size of calcium carbonate can be accurately controlled, and the quality of each batch of products can be kept consistent.

[0029] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 7 and attached Figure 8 As shown, after the spacing of the grinding rollers 6 is adjusted, the controller controls the two sets of motors 7 to rotate in opposite directions. The operation of the motors 7 drives the grinding rollers 6 to rotate inside the grinding chamber 2. The top of the grinding chamber 2 is fixedly installed with a feeding chamber 3, and the left and right ends of the top of the grinding chamber 2 are fixedly installed with discharge ports 4. The feeding chamber 3 and the discharge ports 4 are connected. The material is poured into the feeding chamber 3. The side walls of the feeding chamber 3 and the discharge ports 4 are inclined. The material entering the feeding chamber 3 enters the discharge ports 4 through the inclined side walls and is conveyed between the two sets of grinding rollers 6. At the same time, the operation of the grinding rollers 6 grinds the material entering the grinding chamber 2. The feeding chamber 3 and the discharge ports 4 can process more material at the same time and reduce blockage and stagnation time.

[0030] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, when the material is ground by the grinding roller 6, a first mounting plate 13 is slidably connected to the frame of the mounting bracket 1, and a hinge frame 14 is fixedly installed on the block of the first mounting plate 13. A detachable screen 15 is installed inside the hinge frame 14. The lower side wall of the grinding chamber 2 is set in an inclined state, and the bottom of the grinding chamber 2 is set in a corresponding state with the screen 15. Thus, the grinding roller 6 transports the ground calcium carbonate to the surface of the screen 15. After the ground calcium carbonate is placed on the surface of the screen 15, the controller can control the operation of the electric push rods 19 at both ends. Then, the output end of the electric push rod 19 is fixedly connected to the push plate 18. Thus, the operation of the electric push rod 19 drives the push plate 18 to slide on the top of the second mounting plate 17. Since the first mounting plate 13 A guide rod 16 is fixedly installed at the bottom, and the lower end of the guide rod 16 is in contact with the push plate 18. The push plate 18 is set in an inclined state. When the electric push rod 19 drives the push plate 18 to run, the push plate 18 can drive the first mounting plate 13 to slide on the frame of the mounting frame 1 through the guide rod 16. The first mounting plate 13 drives the screen 15 to move up and down reciprocally through the hinge frame 14. The screen 15 moves up and down reciprocally, and the amplitude generated by the up and down movement of the screen 15 separates the material, thereby separating particles of different sizes. Because the screen 15 is installed in a detachable state inside the hinge frame 14, the screen 15 can be removed from the hinge frame 14 to clean the remaining material on the surface of the screen 15, thereby ensuring the purity and consistency of the final product.
