Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and more specifically to a jaw crusher for high-purity quartz sand. Background Technology

[0002] Key basic materials that are indispensable for high-tech industries such as photovoltaic solar energy, semiconductor chips, optical fiber communication, and precision optics.

[0003] In the process of preparing quartz sand, the first step is to perform primary crushing on the large quartz ore mined. Jaw crushers are widely used as the core equipment in the coarse crushing stage because of their robust structure, simple working principle, strong processing capacity and relatively low maintenance cost. The jaw crusher consists of two jaw plates, a moving jaw and a stationary jaw, forming a crushing chamber. It is a crusher that simulates the movement of an animal's jaws to complete the material crushing operation.

[0004] When using a jaw crusher, the raw materials are fed into the jaw crusher for crushing, which generates a large amount of dust. This dust pollutes the external environment. Currently, it is impossible to perform precise dust suppression, and even after dust suppression is carried out, some dust still escapes to the outside, thus damaging the environment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a jaw crusher for high-purity quartz sand to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a jaw crusher for high-purity quartz sand, comprising a fixed base, a jaw crusher fixedly connected to the top of the fixed base, a jaw inlet movably connected to the jaw crusher, a dust suppression mechanism at the top of the jaw inlet, and dust suction mechanisms on both sides of the dust suppression mechanism. The bottom ends of both the dust suppression mechanism and the dust suction mechanism are fixedly connected to the top of the fixed base. The dust suppression mechanism sprays water mist, and the dust suction mechanism absorbs dust. The dust suppression mechanism includes a water mist nozzle capable of spraying water mist, a connecting groove fixedly connected to the top of the water mist nozzle, and a water inlet pipe fixedly connected to the top of the connecting groove. Water in the water inlet pipe flows through the connecting groove and is sprayed out from the water mist nozzle.

[0007] Furthermore, a moving block is fixedly connected to one side of the connecting groove, and a synchronizing block is fixedly connected to the other side of the connecting groove. A threaded rod is threadedly connected inside the moving block, and a servo motor is fixedly connected to the side of the threaded rod.

[0008] Furthermore, the internal movable connection of the synchronization block is a limit rod, and the bottom end of the limit rod and the servo motor are both fixedly connected to a support plate. The bottom end of the support plate is fixedly connected to a support rod, and the bottom end of the support rod is fixedly connected to the top end of the fixed base.

[0009] Furthermore, the dust collection mechanism includes an output motor that can provide power, an exhaust groove is fixedly connected to the side of the output motor, a rotating shaft is fixedly connected to the side of the output motor near the exhaust groove, and the bottom end of the exhaust groove is fixedly connected to the top end of the fixed base.

[0010] Furthermore, the rotating shaft is located inside the exhaust groove, and a blade assembly is fixedly connected to the side of the rotating shaft away from the output motor. The blade assembly blows the gas to the side away from the output motor. A connecting pipe is fixedly connected to the top of the exhaust groove, and the connecting pipe communicates with the exhaust groove.

[0011] Furthermore, the connecting pipe is located on the side of the blade assembly near the output motor, and a split pipe is fixedly connected to both sides of the top of the connecting pipe. An air intake pipe is fixedly connected to the sides of the two split pipes that are close to each other.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model is equipped with a servo motor, a threaded rod, a connecting groove, and a water mist nozzle. When dust is generated in the jaw nozzle upwards, water in the water inlet pipe flows into the water mist nozzle through the connecting groove and is finally sprayed downwards through the water mist nozzle to suppress dust. At this time, the servo motor starts and drives the threaded rod to rotate. When the threaded rod rotates, it drives the connecting groove to move through the moving block, thereby enabling the water mist nozzle to cool down the area with more dust and improve the accuracy of dust suppression.

[0014] 2. This utility model is equipped with an output motor, a rotating shaft, a blade assembly, and an air inlet pipe. When some dust fails to be settled and diffuses outward, the output motor starts and drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the blade assembly to rotate. When the blade assembly rotates, it blows air outward through the exhaust groove. When the exhaust groove blows air, it generates negative pressure inside, which causes the blade assembly to draw air from both sides of the jaw opening, sucking away the diffused dust and achieving a better dust removal effect.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 and Figure 2 This utility model provides a jaw crusher for high-purity quartz sand, including a fixed base 1, a jaw crusher 2 fixedly connected to the top of the fixed base 1, a jaw opening 3 movably connected to the jaw crusher 2, a dust suppression mechanism 4 provided at the top of the jaw opening 3, and dust collection mechanisms 5 provided on both sides of the dust suppression mechanism 4. The bottom ends of the dust suppression mechanism 4 and the dust collection mechanism 5 are both fixedly connected to the top of the fixed base 1. The dust suppression mechanism 4 sprays water mist, and the dust collection mechanism 5 absorbs the dust.

[0023] Reference Figure 2 , Figure 3 as well as Figure 4The dust suppression mechanism 4 includes a water mist nozzle 408 capable of spraying water mist. A connecting groove 406 is fixedly connected to the top of the water mist nozzle 408. A water inlet pipe 407 is fixedly connected to the top of the connecting groove 406. Water in the water inlet pipe 407 flows through the connecting groove 406 and is sprayed out from the water mist nozzle 408. A moving block 405 is fixedly connected to one side of the connecting groove 406. A synchronization block 409 is fixedly connected to the other side of the connecting groove 406. A threaded rod 404 is threadedly connected inside the moving block 405. A servo motor 403 is fixedly connected to the side of the threaded rod 404. A limit rod 410 is movably connected inside the synchronization block 409. A support plate 402 is fixedly connected to the bottom of both the limit rod 410 and the servo motor 403. A support rod 401 is fixedly connected to the bottom of both the support plate 402. The bottom of the support rod 401 is fixedly connected to the top of the fixed base 1.

[0024] In this embodiment, when the servo motor 403 starts, it drives the threaded rod 404 to rotate, which in turn causes the moving block 405 to move. When the moving block 405 moves, it drives the connecting groove 406 to move, which in turn causes the water mist nozzle 408 below the connecting groove 406 to move. The water mist nozzle 408 can automatically find the location with more dust to improve the dust suppression effect. When the water mist nozzle 408 is suppressing dust, the side of the connecting groove 406 drives the synchronization block 409 to move on the side of the threaded rod 404, thereby ensuring the stability of the connecting groove 406 when it moves. The support rod 401 and the support plate 402 can provide support, thereby ensuring the overall stability of the dust suppression mechanism 4 when it is working.

[0025] Reference Figure 2 and Figure 5 The vacuuming mechanism 5 includes an output motor 501 that provides power. An exhaust groove 504 is fixedly connected to the side of the output motor 501. A rotating shaft 502 is fixedly connected to the side of the output motor 501 near the exhaust groove 504. The bottom end of the exhaust groove 504 is fixedly connected to the top end of the fixed base 1. The rotating shaft 502 is located inside the exhaust groove 504. A blade assembly 503 is fixedly connected to the side of the rotating shaft 502 away from the output motor 501. The blade assembly 503 blows the gas to the side away from the output motor 501. A connecting pipe 505 is fixedly connected to the top end of the exhaust groove 504. The connecting pipe 505 communicates with the exhaust groove 504 and is located on the side of the blade assembly 503 near the output motor 501. Diverter pipes 506 are fixedly connected to both sides of the top end of the connecting pipe 505. An air inlet pipe 507 is fixedly connected to the sides of the two diverter pipes 506 that are close to each other.

[0026] In this embodiment, the output motor 501 drives the blade assembly 503 to rotate via the rotating shaft 502. When the blade assembly 503 rotates, it blows the gas in the exhaust groove 504 outward, thereby creating a negative pressure in the exhaust groove 504. Under the action of the negative pressure, the connecting pipe 505 draws air downward, causing the two air inlet pipes 507 connected to the connecting pipe 505 to simultaneously flow into the connecting pipe 505. At this time, the air inlet pipes 507 on both sides of the jaw mouth 3 simultaneously draw air inward, which can absorb the scattered dust in time. The absorbed dust enters the exhaust groove 504 through the moving block 405. At this time, the gas containing dust can be uniformly treated, and the quartz sand inside can be recycled again, which can save costs.

[0027] The working principle of this utility model is as follows: When crushing quartz sand, the raw material enters the jaw crusher 2 through the jaw inlet 3, and is then crushed by the jaw crusher 2.

[0028] During the crushing process, water flows into the inlet pipe 407. After flowing in the connecting groove 406, the water finally sprays downward through the water mist nozzle 408 to suppress dust. When the water mist nozzle 408 is suppressing dust, the servo motor 403 is started. When the servo motor 403 is started, it drives the threaded rod 404 to rotate. When the threaded rod 404 rotates, it causes the moving block 405 to move. When the moving block 405 moves, it drives the connecting groove 406 to move, which in turn causes the water mist nozzle 408 below the connecting groove 406 to move. The water mist nozzle 408 can automatically find the location with more dust to improve the dust suppression effect.

[0029] When some dust is not suppressed by the water mist nozzle 408 and is dispersed outward, the output motor 501 starts and drives the rotating shaft 502 to rotate. When the rotating shaft 502 rotates, it drives the blade assembly 503 to rotate. When the blade assembly 503 rotates, it blows the gas in the exhaust groove 504 outward, thereby creating a negative pressure in the exhaust groove 504. Under the action of negative pressure, the connecting pipe 505 will draw air downward, which will cause the two air inlet pipes 507 connected to the connecting pipe 505 to flow into the connecting pipe 505 simultaneously. At this time, the air inlet pipes 507 on both sides of the jaw mouth 3 will draw air inward simultaneously, which can absorb the dispersed dust. The absorbed dust enters the exhaust groove 504 through the moving block 405 for unified collection, avoiding environmental impact.

[0030] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
