Description

Technical Field

[0001] This application relates to the technical field of calcium carbonate processing, and in particular to a raw material grinding device for calcium carbonate processing. Background Art

[0002] Calcium carbonate uses limestone as the main raw material. After mechanical crushing and grinding, through processes such as forming dry powder or wet powder and then classification, products meeting different particle size requirements are formed, which are suitable for many fields such as papermaking, plastics, rubber, printing ink, chemical building materials, sealing materials, daily chemicals, food, and medicine. The formed calcium carbonate industrial chain is called the calcium carbonate industry.

[0003] The existing calcium carbonate grinding device includes a grinding barrel, grinding balls, and a rotating assembly for driving the grinding barrel to rotate. The grinding balls are arranged in the grinding barrel. The raw materials are put into the grinding barrel, and the rotating assembly drives the grinding barrel to rotate. The grinding barrel drives the grinding balls to do circular motion, and the grinding balls complete the grinding of the raw materials during the movement. After grinding is completed, the machine is stopped, and the raw materials in the grinding barrel are poured out and collected.

[0004] In view of the above related technologies, after grinding is completed, it is necessary to stop the machine to take out the ground raw materials, which is time-consuming and laborious, so there is a defect of low grinding efficiency of calcium carbonate raw materials. Content of the Utility Model

[0005] In order to improve the working efficiency of grinding calcium carbonate raw materials, this application provides a raw material grinding device for calcium carbonate processing.

[0006] The raw material grinding device for calcium carbonate processing provided by this application adopts the following technical solutions:

[0007] A raw material grinding device for calcium carbonate processing includes a grinding barrel, grinding balls, and a rotating assembly for driving the grinding barrel to rotate. The grinding balls are arranged in the grinding barrel. The grinding barrel is vertically arranged, and the bottom end of the grinding barrel is open. A support plate is arranged at the grinding barrel. The support plate is horizontally arranged, and the lower surface of the support plate is fixedly connected with legs. The grinding barrel penetrates through the support plate and is rotationally connected with the support plate. A filter screen is arranged in the grinding barrel. The filter screen is horizontally arranged. The grinding balls are above the filter screen. A vibration assembly for driving the filter screen to vibrate up and down is arranged on the grinding barrel.

[0008] By adopting the above technical solution, the raw materials are put into the grinding barrel. The rotating component drives the grinding barrel to rotate. The grinding barrel drives the grinding balls and the filter screen to move. During the movement of the grinding balls, the raw materials are ground. The debris generated by grinding falls onto the filter screen. The filter screen screens the debris. The debris that passes through the filter screen falls from the filter screen and is collected. The debris that does not pass through the filter screen is ground again by the grinding balls. At the same time, during the process of the filter screen screening the debris, the vibrating component drives the filter screen to vibrate, so that the filter screen is not easily blocked. The qualified raw material debris can be collected under the grinding barrel without stopping the machine, saving time, and thus improving the working efficiency of grinding calcium carbonate raw materials.

[0009] Optionally, the rotating component includes a motor and a first gear. The motor is fixedly connected to the upper surface of the support plate. The output shaft of the motor is fixedly connected to the first gear. A second gear is arranged on the grinding barrel. The grinding barrel passes through the second gear and is fixedly connected to the second gear. The first gear and the second gear are meshed.

[0010] By adopting the above technical solution, the motor is started. The motor drives the first gear to rotate. The first gear drives the second gear to rotate. The second gear drives the grinding barrel to rotate. Thus, the rotating component realizes the function of driving the grinding barrel to rotate.

[0011] Optionally, a chute is formed through the side wall of the grinding barrel. The length direction of the chute is parallel to the length direction of the grinding barrel. A sliding plate is slidably connected in the chute of the grinding barrel. The sliding plate is horizontally arranged. One end of the sliding plate close to the inside of the grinding barrel is connected to the filter screen.

[0012] By adopting the above technical solution, during the process of the vibrating component driving the filter screen to vibrate, the filter screen and the sliding plate move simultaneously. At the same time, the setting of the sliding plate and the chute realizes the sliding connection between the filter screen and the grinding barrel.

[0013] Optionally, the vibrating component includes a vibrating block and a guiding block. The vibrating block is connected to one end of the sliding plate away from the filter screen. The guiding block is fixedly connected to the upper surface of the support plate. The upper surface of the guiding block is set as an inclined plane.

[0014] By adopting the above technical solution, under the guiding action of the sliding plate, the grinding barrel drives the filter screen to move simultaneously. At the same time, the sliding plate drives the vibrating block to move. During the process of the vibrating block making a circular motion, under the guiding action of the inclined plane of the guiding block, the vibrating block moves upward. The vibrating block drives the sliding plate to move upward. The sliding plate drives the filter screen to move. When the vibrating block and the guiding block are separated, the filter screen moves downward under its own gravity and the gravity of the material above. The filter screen drives the sliding plate to move. The sliding plate drives the vibrating block to move, so that the vibrating block returns to its original position. Thus, the vibrating component realizes the function of the up-and-down vibration of the filter screen.

[0015] Optionally, the slide plate is fixedly connected to one end close to the filter screen with an arc plate, the arc plate is fixedly connected to the filter screen on the side facing the filter screen, and the arc plate abuts against the inner wall of the grinding barrel on the side away from the filter screen.

[0016] By adopting the above technical solution, during the process of the filter mesh vibrating up and down, the filter mesh drives the arc plate to move, and the arc plate always blocks the chute, making it difficult for raw material debris to enter the chute, and thus the raw material is not easy to affect the up and down movement of the slide plate.

[0017] Optionally, the end of the slide away from the filter is fixedly connected to a baffle, the baffle is arc-shaped, the side of the baffle away from the slide is fixedly connected to the vibration block, and the side of the baffle facing the grinding barrel abuts against the outer surface of the grinding barrel.

[0018] By adopting the above technical solution, when the skateboard moves up and down, the skateboard drives the baffle to move, and the baffle drives the vibration block to move. At the same time, the baffle always blocks the slide groove, making it difficult for external objects to enter the slide groove.

[0019] Optionally, a roller is connected to the lower surface of the vibration block.

[0020] By adopting the above technical solution, the vibration block drives the roller to move during its movement. When the roller contacts the inclined surface of the guide block, the roller moves upward under the guidance of the inclined surface of the guide block, and the roller drives the vibration block to move upward. The setting of the roller makes it difficult for the vibration block and the guide block to contact each other, thereby making it difficult for the guide block and the vibration block to rub against each other.

[0021] Optionally, a spring is provided under the slide plate, and the spring is fixed between the slide plate and the bottom wall of the slide groove.

[0022] By adopting the above technical solution, when the slide plate moves downward, the spring contracts and plays a buffering role, so that the slide plate is not likely to collide violently with the grinding barrel, thereby making the slide plate less likely to be damaged.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the grinding balls grind the raw materials, the filter screens the generated debris. The debris that passes through the filter screen is collected at the bottom of the grinding barrel. There is no need to stop the machine to take out the material, which saves time and improves the efficiency of grinding calcium carbonate raw materials.

[0025] 2. The vibration component can drive the filter to vibrate up and down, making the filter less likely to be blocked;

[0026] 3. The curved plate blocks the chute, making it difficult for the raw materials to enter the chute, thereby facilitating the up and down movement of the slide. Description of the Drawings

[0038] The vibration assembly 5 includes vibration blocks 51 and guiding blocks 52. There are two vibration blocks 51 and two guiding blocks 52 respectively. The vibration blocks 51 are connected to one end of the sliding plate 14 away from the filter screen 4 in a one-to-one correspondence. The vibration blocks 51 are located outside the grinding barrel 1. Roller wheels 8 are rotatably connected to the lower surfaces of the vibration blocks 51.
