Description

Technical Field

[0001] The utility model relates to the technical field of quartz gemstones, in particular to a quartz gemstone grinding device with a screening structure. Background Art

[0002] Jiaobaoshi is a high-quality hard refractory clay produced in Zibo, Shandong Province, China. After high-temperature calcination, it has the characteristics of stable volume, high strength and low water absorption. During the processing, it is usually necessary to grind and screen it to select the appropriate size of Jiaobaoshi.

[0003] Existing, such as Chinese patent publication number CN217615030U discloses a coke grinding device with a screening structure, which includes an operating table, a servo motor vertically fixedly mounted on the top of the mounting plate, a grinding disc fixedly connected to the output end of the servo motor, a grinding barrel movably mounted on the top of the operating table and a screening box fixedly mounted on the bottom of the operating table. The utility model is provided with a vibration mechanism and a screening mechanism, and the mounting blocks on both sides of the screen are respectively inserted into the fixed grooves, and the fixed grooves are respectively fixedly mounted on one side of the movable baffle and one side of the inner wall of the screening box, and there is a height difference between the relative fixed grooves. After the screen is installed, a slope will be generated, which is more convenient for large-particle coke to be discharged. At the same time, the density of the three-layer screen increases from top to bottom, which is more convenient for screening cokes of different coarsenesses during use. The finer powder will fall to the bottom layer, and the coarser particles will be screened through the screen to the inside of the receiving box for secondary grinding.

[0004] Although the above patent solves the problem of making it easier to screen coarse gemstones of different coarsenesses during use, the finer powder will fall to the bottom layer, and the coarser particles will be screened through the screen to the inside of the receiving box for secondary grinding, but there are still some shortcomings. For example, after the device screens out the coarser coarse gemstones, they will accumulate in the receiving box. When re-screening is required, the coarser coarse gemstones in the receiving box need to be manually poured into the grinding box for grinding, which greatly wastes manpower and requires workers to supervise at all times to prevent the coarse gemstones in the receiving box from being filled up, which is very inconvenient. Therefore, it is necessary to propose a new coarse gemstone grinding device with a screening structure. Utility Model Content

[0026] The lifting mechanism 7 includes a three-stage collection box 701 , a slot 702 is provided on one side of the inner wall of the three-stage collection box 701 , two first dampers 703 are fixedly installed on one side of the inner wall of the three-stage collection box 701 , and a push plate 704 is fixedly installed on one side of the outer wall of the two first dampers 703 .

[0027] The effect achieved by the entire embodiment 1 is that, by setting the lifting groove 8 and the first electric telescopic rod 11, it is inevitable that some of the coke gems after being ground by the grinder 1 will be larger. After these particles are screened and enter the lifting mechanism 7, the servo motor 10 can be started to drive the threaded rod 9 to rotate, thereby driving the lifting mechanism 7 to move upward. When it moves to the top, the first electric telescopic rod 11 is started to push the push plate 704 through the slot 702, and the large particles of coke gems are returned to the grinder 1 according to the return groove 12 for grinding. There is no need to manually take out the large particles of coke gems and then put them back into the grinder 1, thereby freeing up manpower and improving the grinding efficiency of coke gems.

A baffle 20 is fixedly installed on the output ends of the two second electric telescopic rods 19, and the bottom end of the baffle 20 passes through the top of the inner wall of the screening box 3. A primary collecting box 21 is movably inserted on the inner surface wall of the screening box 3. Two groups of second dampers 22 are fixedly installed on the inner surface wall of the screening box 3, and the top ends of the two groups of second dampers 22 are respectively connected to the bottom ends of the two screening plates 4.

The screened medium-grained coke gems and small-grained coke gems will be collected by the secondary collection box 6 and the primary collection box 21. When the screening is completed, the operator can directly open the shielding door 15 to collect the medium-grained coke gems and small-grained coke gems, which improves the convenience during recycling.

[0030] The working principle of the whole device is as follows: the coke gemstones to be screened are poured into the grinder 1 through the inlet of the grinder 1, and are ground by the grinder 2. After the grinding is completed, they fall into the screening box 3, and the vibration motor 14 is started to drive the connecting plate 13 to vibrate, so that the two screening plates 4 are shaken under the limit of the second damper 22, and then fall into the top screening plate 4 first to screen the large coke gemstones. The screened large gemstones will enter the lifting mechanism 7, and the unscreened gemstones will continue to be screened through the bottom screening plate 4. At this time, the medium-sized coke gemstones will be screened and enter the secondary collection box 6, and the small-sized gemstones will enter the secondary collection box 6. The stones will pass through the screening plate 4 and fall into the collection box. At this time, the operator only needs to open the shielding door 15 to take out the primary collection box 21 and the secondary collection box 6. When the large-particle coke gemstones in the lifting mechanism 7 need to be re-ground, first start the second electric telescopic rod 19 to drive the baffle 20 to move downward to block the outlet at the top of the screening box 3, and then start the two servo motors 10 to drive the threaded rod 9 to rotate, and move the lifting mechanism 7 upward to the top of the storage tank 5. At this time, start the first electric telescopic rod 11 to drive the push plate 704 to push the large-particle coke gemstones into the return trough 12, and then fall into the grinder 1 for grinding.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
