Description

Technical Field

[0001] The present application relates to the technical field of grinders, and in particular to an ultrafine calcium carbonate grinding device. Background Art

[0002] Ground calcium carbonate powder is widely used in construction, cosmetics, medicine, food, and industry. Accordingly, grinding equipment is required to produce calcium carbonate powder.

[0003] Grinding equipment is a commonly used industrial equipment that can crush and grind materials into the required particle size through friction and collision. During the production process, the operator pours the raw materials to be ground into the grinding equipment, which will squeeze and crush the raw materials through the grinding rollers, and then blow the calcium carbonate powder to the air outlet at the top of the equipment through the air inlet at the bottom, thereby obtaining calcium carbonate powder.

[0004] However, in actual use, common grinding equipment cannot separate calcium carbonate dust well when blowing calcium carbonate powder out from the top of the equipment, and some particles that have not been finely ground may be mixed in it, resulting in inconsistent quality of the calcium carbonate powder blown out by the grinding equipment, affecting its use. For this reason, the present application provides an ultrafine calcium carbonate grinding device. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the grinding equipment cannot separate the calcium carbonate dust well when blowing the calcium carbonate powder out from the top of the equipment. The present application provides an ultrafine calcium carbonate grinding device.

[0020] By adopting the above technical solution, the inside of the device can be inspected by opening the inspection door. After the inspection is completed, the inspection door can be manually closed to allow the limit plate to enter the inside of the block.

[0021] Furthermore, grooves are symmetrically provided inside the clamping block, springs are fixedly connected inside the grooves, a limiting block is slidably connected inside the grooves, and one end of the spring is fixedly connected to one end of the limiting block.

The ground calcium carbonate powder is blown to the separation component 11 above, and the separation component 11 is started at this time. Through the high-speed rotation of the separation component 11, when the dust contacts the separation component 11, the dust with heavier weight is thrown out due to the action of centrifugal force and falls into the grinding disc 6, and is continued to be ground by the grinding component 9 and the grinding disc 6, while the qualified dust is blown out through the discharge port 12 on the top. The separation of the calcium carbonate powder by the separation component 11 greatly improves the quality of the grinding of the calcium carbonate powder, thereby grinding the calcium carbonate powder more finely.

[0038] When in use, first start the hydraulic cylinder 97 to push the connecting block 98 to move. When the connecting block 98 moves, it can drive the sliding rod 96 to slide on the guide column 95. According to the support and guidance of the sliding rod 96 and the guide column 95, the hydraulic cylinder 97 can be prevented from shaking and deviating. At the same time, when the hydraulic cylinder 97 drives the connecting block 98 to move, the rotating rod 99 will rotate. When the rotating rod 99 rotates, the transmission arm 910 will drive the grinding roller 912 to fit closely with the inner wall of the grinding disc 6. Through the operation of the hydraulic cylinder 97, the pressure between the grinding roller 912 and the grinding disc 6 can be always maintained, so as to better grind the calcium carbonate.

[0039] Reference Figure 1 , Figure 2 and Figure 4 The separation component 11 includes a support plate 111 fixedly connected to one side of the support block 10, a sub-motor 112 is fixedly connected to the top of the support plate 111, a reducer 113 is fixedly connected to the output end of the sub-motor 112, a pulley 114 is fixedly connected to the top of the reducer 113, a pulley 115 is fixedly connected to the top of the separation component 11, a transmission belt 116 is sleeved on the outer walls of the pulley 114 and the pulley 115, a connecting shaft 117 is fixedly connected to the bottom of the pulley 115, a connecting shaft 118 is fixedly connected to the bottom of the connecting shaft 117, the connecting shaft 117 and the connecting shaft 2 118 are both located inside the shell 7, and a plurality of separation blades 119 are evenly fixedly connected to the outer wall of the connecting shaft 2 118.

[0040] When in use, first start the auxiliary motor 112 to drive the pulley 114 to rotate. When the pulley 114 rotates, according to the transmission guidance of the transmission belt 116, the pulley 2 115 will also be driven to rotate. Through the high-speed rotation of the pulley 2 115, the connecting shaft 117 and the connecting shaft 2 118 at the bottom will drive the separation blade 119 to rotate at high speed. When the external hot air blows the calcium carbonate to the top and touches the separation blade 119, the heavier dust will be thrown out due to the centrifugal force and fall back on the grinding disc 6 to continue grinding, while the qualified dust will be blown out normally through the discharge port 12, so as to separate the ground calcium carbonate powder and improve the grinding quality and quality of the calcium carbonate.

[0041] Reference Figure 1 and Figure 5 An inspection port is provided on the shell 7, and an inspection door 13 is hinged in the inspection port. A clamping block 131 is fixedly connected to the shell 7, and a limiting plate 132 is fixedly connected to one side of the inspection door 13. Grooves are symmetrically provided inside the clamping block 131, and springs 133 are fixedly connected inside the grooves. A limiting block 134 is slidably connected in the groove, and one end of the spring 133 is fixedly connected to one end of the limiting block 134.

[0042] When in use, the interior of the device can be inspected by opening the inspection door 13. After the inspection is completed, the inspection door 13 can be manually closed to allow the limit plate 132 to enter the interior of the block 131. At this time, the limit plate 132 will push the limit block 134 into the groove and squeeze the spring 133 to contract. When the limit plate 132 passes through the groove, the limit block 134 will rise according to the rebound of the spring 133. The raised limit block 134 can limit the limit plate 132 to prevent the inspection door 13 from opening automatically during the grinding and use of the device.

[0043] The implementation principle of the ultrafine calcium carbonate grinding device of this embodiment is as follows: when in use, firstly, the calcium carbonate raw material is poured into the shell 7 from the raw material inlet 8 and falls on the grinding disc 6, and then the hydraulic cylinder 97 is started to push the connecting block 98 to move. When the connecting block 98 moves, the sliding rod 96 can be driven to slide on the guide column 95. According to the support and guidance of the sliding rod 96 and the guide column 95, the hydraulic cylinder 97 can be prevented from shaking and deviating. At the same time, when the hydraulic cylinder 97 drives the connecting block 98 to move, the rotating rod 99 will rotate. When the rotating rod 99 rotates, the transmission arm 910 will drive the grinding roller 912 to fit closely with the inner wall of the grinding disc 6. Through the operation of the hydraulic cylinder 97, the pressure between the grinding roller 912 and the grinding disc 6 can be always maintained, so as to better grind the calcium carbonate. Then, the main motor 2 is started to drive the main shaft 4 to rotate. Through the operation of the main shaft 4, the grinding disc 6 will be driven to rotate together. Through the cooperation of the grinding disc 6 and the grinding roller 912, the calcium carbonate raw material is finely ground.

[0044] Secondly, during the grinding process, an external blower can be connected to the air inlet on one side of the fixed frame 5, and the external hot air can enter the device through the air inlet. Under the influence of the external hot air, the ground calcium carbonate powder will be blown to the separation blade 119 above. At this time, the auxiliary motor 112 is started to drive the pulley 114 to rotate. When the pulley 114 rotates, according to the transmission guidance of the transmission belt 116, the pulley 2 115 will also be driven to rotate. Through the high-speed rotation of the pulley 2 115, the connecting shaft 117 and the connecting shaft 2 118 at the bottom will drive the separation blade 119 to rotate at a high speed. When the external hot air blows the calcium carbonate to the top and touches the separation blade 119, the dust with a larger weight will be thrown out due to the action of centrifugal force and fall back on the grinding disc 6 to continue grinding, while the qualified dust will be blown out normally through the discharge port 12, so as to separate the ground calcium carbonate powder and improve the grinding quality and quality of calcium carbonate.

[0045] In addition, when the device needs to be inspected, it is only necessary to open the inspection door 13 to inspect the inside of the device. After the inspection is completed, the inspection door 13 can be manually closed to allow the limit plate 132 to enter the inside of the block 131. At this time, the limit plate 132 will push the limit block 134 into the groove and squeeze the spring 133 to contract. When the limit plate 132 passes through the groove, the limit block 134 will be lifted up according to the rebound of the spring 133. The lifted limit block 134 can limit the limit plate 132 to prevent the inspection door 13 from opening automatically during the grinding and use of the device.
