Description

Technical Field

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

[0002] Heavy calcium carbonate is mainly composed of calcium carbonate, which is produced by mechanical crushing and grinding of natural carbonate minerals such as calcite, marble, and limestone. Heavy calcium carbonate has a wide range of uses and is an important filler and expander in industries such as plastics, rubber, coatings, papermaking, and building materials. In actual processing of heavy calcium carbonate, a grading device is required to classify heavy calcium carbonate of different particle sizes. In practice, it has the advantages of simple operation, stable screening, and safe use.

[0003] Existing grading devices typically use inclined screen structures for rolling sieving of heavy calcium carbonate. This sieving method cannot adequately screen heavy calcium carbonate, resulting in the presence of particles with different sizes within the heavy calcium carbonate, thus reducing the practicality of the existing grading device. Furthermore, the screen structure can become clogged during sieving of heavy calcium carbonate, and the lack of a clearing mechanism can affect subsequent sieving of heavy calcium carbonate, posing a potential risk to the continued use of the existing grading device.

[0015] Furthermore, the filter pore size of the multiple sets of arc-shaped screens decreases sequentially from top to bottom.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a heavy calcium carbonate grading device, which has the following beneficial effects:

[0018] (1) This utility model is equipped with mounting shafts and stirring blades. In actual use of the heavy calcium carbonate grading device, heavy calcium carbonate can be put into the inside of the screening box through the feed hopper, and then the feed inlet of the feed hopper can be blocked with a sealing cover. Using the control panel, the self-locking forward and reverse motor can be turned on. The output end of the self-locking forward and reverse motor can drive the worm to rotate. Since the worm meshes with multiple sets of worm wheels, the rotating worm can drive multiple sets of worm wheels to rotate. The rotating multiple sets of worm wheels can drive multiple sets of stirring blades to rotate through multiple sets of mounting shafts. The rotating multiple sets of stirring blades can stir the heavy calcium carbonate inside multiple sets of semi-circular plates. Calcium carbonate is separated and screened into multiple sizes by using multiple sets of arc-shaped screens with progressively smaller pore sizes from top to bottom. After grading and screening, the electric slide valve is opened and closed using the control panel. Then, multiple sets of threaded through holes and multiple sets of threaded caps are engaged with each other. The operator manually removes the multiple sets of threaded caps counterclockwise. Afterward, multiple sizes of heavy calcium carbonate can be removed sequentially through the hopper and multiple sets of threaded through holes. The installed shaft and agitator blades enable thorough screening of heavy calcium carbonate, improving the practicality of the heavy calcium carbonate grading device.

[0019] (2) This utility model is equipped with an air storage box and an installation cover. According to the above operation, heavy calcium carbonate needs to be screened through multiple sets of arc-shaped screens. Using the control panel, the air pump is turned on and the electric telescopic rod is extended and retracted intermittently. Air can enter the interior of the air storage box through the air guide pipe. The air inside the air storage box can enter the interior of multiple sets of jet pipes through multiple sets of connecting pipes. Finally, the air can be sprayed out through multiple sets of high-pressure nozzles. The sprayed air can blow out the blockages inside the multiple sets of arc-shaped screens. At the same time, the telescopic electric telescopic rod can make the sawtooth plate move up and down intermittently. Since the sawtooth plate meshes with multiple sets of gears, the up and down sawtooth plate can drive multiple sets of gears to rotate clockwise and counterclockwise. The clockwise and counterclockwise rotating multiple sets of gears can drive multiple sets of jet pipes to rotate. At this time, the operating angle of multiple sets of high-pressure nozzles can be adjusted to ensure that the sprayed air can fully clear the blockage. With the air storage box and installation cover, there is a blockage clearing structure, which can clean the blockages in the filter structure and ensure the continuous use of the heavy calcium carbonate grading device.

[0038] In one embodiment, the filter pore size of the multiple sets of arc-shaped screens 3 decreases sequentially from top to bottom.

[0039] Working principle:

[0040] In actual use of the heavy calcium carbonate grading device, heavy calcium carbonate can be fed into the screening box 1 through the feed hopper 6, and then the feed inlet of the feed hopper 6 can be blocked with the sealing cover 7. Using the control panel, the self-locking forward and reverse motor 16 can be started. The output end of the self-locking forward and reverse motor 16 can drive the worm 15 to rotate. Since the worm 15 is meshed with multiple sets of worm wheels 17, the rotating worm 15 can drive the multiple sets of worm wheels 17 to rotate. The rotating multiple sets of worm wheels 17 can drive the multiple sets of stirring blades 5 to rotate through multiple sets of mounting shafts 4. The rotating multiple sets of stirring blades 5 can stir multiple sets of semi-circular plates. 2. The internal heavy calcium carbonate is separated and screened by multiple sets of arc-shaped screens 3, whose filter pore sizes decrease from top to bottom. After grading and screening, the electric slide valve 23 is opened and closed using the control panel. Then, the multiple sets of threaded through holes 24 and multiple sets of threaded covers 25 are engaged by the threaded connections. The operator manually removes the multiple sets of threaded covers 25 counterclockwise. Afterward, the heavy calcium carbonate of various sizes can be removed sequentially through the hopper 22 and the multiple sets of threaded through holes 24. The installed shaft 4 and the stirring blades 5 can further process the heavy calcium carbonate. Thorough screening improves the usability of the heavy calcium carbonate grading device. As described above, heavy calcium carbonate needs to be screened through multiple sets of arc-shaped screens 3. Using the control panel, the air pump 10 is activated, simultaneously extending and retracting the electric telescopic rod 19. Air enters the air storage tank 9 through the air guide pipe 11, and then enters the air jet pipes 13 through multiple sets of connecting pipes 18. Finally, the air is ejected through multiple sets of high-pressure nozzles, blowing out blockages inside the arc-shaped screens 3. Simultaneously, the telescopic rod... The electric telescopic rod 19 allows the serrated plate 20 to move up and down intermittently. Since the serrated plate 20 meshes with multiple sets of gears 21, the up-and-down movement of the serrated plate 20 can drive the multiple sets of gears 21 to rotate clockwise and counterclockwise. The clockwise and counterclockwise rotation of the multiple sets of gears 21 can drive the multiple sets of jet pipes 13 to rotate. At this time, the operating angle of multiple sets of high-pressure nozzles can be adjusted to ensure that the sprayed air can fully perform the unblocking work. Through the set air storage box 9 and mounting cover 12, it has an unblocking structure that can clean the blockage of the filter structure, thus ensuring the continuous use of the heavy calcium carbonate grading device.
