Description

Technical Field

[0001] The invention relates to the technical field of calcium carbonate processing, in particular to fine processing equipment for calcium carbonate. Background Art

[0002] Calcium carbonate processing refers to the processing of natural ores into calcium carbonate products of different particle sizes and purities through crushing, grinding, grading and other processes. Calcium carbonate processing belongs to the chemical raw material processing industry and is widely used in construction, plastics, papermaking, coatings, rubber and other fields. The industrial chain of the calcium carbonate processing industry covers multiple links such as raw material mining, processing and manufacturing, and product sales. In the raw material mining link, companies need to mine marble, limestone and other ores from mines; in the processing and manufacturing link, companies need to crush, grind, grade and other processes on the raw materials to produce calcium carbonate products of different specifications and qualities; in the product sales link, companies need to sell products to customers in the construction, plastics, papermaking and other industries.

[0003] In the prior art, during the production process of calcium carbonate, it is often necessary to break up large pieces of calcium carbonate raw materials and grind them into powder. During this process, the powdered calcium carbonate needs to undergo multiple subdivision filtrations, and then the calcium carbonate powder that does not meet the particle size standards needs to be discharged and re-refined and ground. Then the staff needs to take out the substandard calcium carbonate powder in the processing equipment and re-introduce it into the feeding place of the processing equipment. At this time, the staff needs to stop the machine to ensure the safety of the operation, which will affect the processing efficiency of calcium carbonate during batch fine processing. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a fine processing equipment for calcium carbonate to solve the problems raised in the above background technology.

[0010] By adopting the above technical solution, when in use, the staff connects the negative pressure centrifugal fan to the second flange joint on one side of the separation box through an external pipeline, and then adds the calcium carbonate raw material into the interior of the top cover through the feeding hopper pipe, and then the crushed and ground calcium carbonate will fall to the top of the screening net, and then the small-particle calcium carbonate powder will pass through the mesh holes on the surface of the screening net and fall into the interior of the receiving tank, and then the large-particle calcium carbonate powder will pass through the inclined surface of the screening net and fall into the interior of the receiving tray. At this time, the calcium carbonate powder inside the receiving tray will enter the interior of the feed box through the two feeding holes after accumulation, and then the calcium carbonate powder will accumulate on the surface of the support plate when entering the interior of the feed box, and then when the top of the support plate When the accumulated weight of calcium carbonate exceeds the elastic force of the two second springs, the support plate will be under pressure to drive the feeler rod to move downward. At this time, when the feeler rod contacts the pressure sensor, the pressure sensor will feedback the electrical signal and start the negative pressure centrifugal fan. Then, the calcium carbonate powder inside the feed box will be drawn upward under the action of negative pressure suction. At this time, the calcium carbonate powder inside the feed box will enter the separation box through the connecting pipe, and then the filter plate inside the separation box will block the calcium carbonate powder and make it fall to the inside of the top cover through the inclined surface of the filter plate. Then, the calcium carbonate powder entering the top cover will be re-ground, thereby achieving the effect of automatic circulation grinding of calcium carbonate powder that does not meet the particle size standard.

[0011] Preferably, a plurality of static crushing discs are fixedly mounted on the inner circular wall of the crushing pot, and the inner diameters of the plurality of static crushing discs decrease sequentially from top to bottom; a plurality of dynamic crushing discs are fixedly sleeved on the outer circular wall of the connecting shaft, and the outer diameters of the plurality of dynamic crushing discs decrease sequentially from top to bottom; a second material guide cover is provided inside the crushing pot, and the top surface of the second material guide cover is fixedly mounted to the bottom surface of the static crushing disc.

At this time, under the action of the outer teeth of the dynamic crushing disk and the inner teeth of the static crushing disk, the calcium carbonate raw material will be broken into small pieces, thereby achieving the effect of crushing the calcium carbonate raw material.

At this time, the calcium carbonate raw material on the top of the dynamic grinding disc will enter the inside of the receiving trough under the scraping of the two pushing plates, and then the calcium carbonate raw material inside the receiving trough will enter between the dynamic grinding disc and the static grinding disc through the feed hole, and then the rotating dynamic grinding disc and the stationary static grinding disc will grind the calcium carbonate raw material, and then the ground calcium carbonate raw material will fall through the discharge hole, thereby achieving the effect of grinding the calcium carbonate raw material.

At the same time, the rotating cleaning rod will drive the scraper at its bottom to rotate. At this time, the scraper will push the large-particle calcium carbonate powder inside the receiving tray to move, thereby facilitating the calcium carbonate powder inside the receiving tray to be pushed into the inside of the feed box.

[0017] Preferably, the outer circular wall surface of the connecting shaft is fixedly sleeved with a first mounting frame, the bottom surface of the first mounting frame is rotatably connected to two pressing blocks, the inner circular wall surface of the first mounting frame is fixedly sleeved with two mounting caps, the inner part of the mounting cap is movably sleeved with a first spring, the inner part of the mounting cap is movably sleeved with a first connecting column, and the bottom surface of the first connecting column is fixedly mounted to the top surface of the pressing block.

[0018] By adopting the above technical solution, when the connecting shaft rotates, the first mounting frame will drive the two pressing blocks to rotate simultaneously, and then the pressing blocks can float up and down under the action of the rebound force of the two first springs, and then the moving pressing blocks will press down the calcium carbonate raw materials inside the top cover, thereby preventing the calcium carbonate raw materials from entering between the static crushing disk and the dynamic crushing disk during crushing.

[0019] Preferably, a plurality of shields are fixedly installed between the plurality of static crushing discs.

[0026] When the feeler rod contacts the pressure sensor, the pressure sensor will feed back an electrical signal to start the negative pressure centrifugal fan, and then the calcium carbonate powder inside the feed box will be drawn upward under the action of negative pressure suction. At this time, the calcium carbonate powder inside the feed box will enter the separation box through the connecting pipe, and then the filter plate inside the separation box will block the calcium carbonate powder and make it fall to the inside of the top cover through the inclined surface of the filter plate, and then the calcium carbonate powder entering the top cover will be re-ground, thereby achieving the effect of automatic circulation grinding of calcium carbonate powder that does not meet the particle size standard.
