Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand production and processing, specifically to a multi-stage crushing device for quartz sand processing. Background Technology

[0002] With the rapid development of industries such as construction, glass manufacturing, and electronics, the demand for quartz sand, as an important industrial raw material, is increasing daily, and the requirements for product particle size and purity are constantly rising. However, traditional quartz sand crushing devices mostly adopt a single crushing method, which has problems such as low crushing efficiency, high energy consumption, and uneven particle size of finished products, making it difficult to meet the needs of fine production. At the same time, they have poor adaptability when processing raw materials with different hardness and particle size, which can easily lead to serious equipment wear and increased maintenance costs. Therefore, the development of a multi-stage crushing device for quartz sand processing, which optimizes the crushing effect, improves production efficiency and product quality through a multi-stage crushing process, has important practical significance.

[0003] Application number CN202220902325.9 discloses a multi-functional multi-stage crushing device for quartz sand processing, comprising four bases, with a housing fixedly connected to the upper surface of each base. Dust collection mechanisms are provided at both ends of each housing, and a protective cover is fixedly connected to the upper surface of each housing. A crushing mechanism is also provided on the upper surface of each housing. The dust collection mechanism includes a fixed box fixedly connected to both ends of the housing, an air pipe fixedly connected to the upper surface of the fixed box, a dust collection fan fixedly connected to the end of the air pipe away from the fixed box, a connecting pipe fixedly connected to the opposite ends of two fixed boxes, and an air plate fixedly connected to the end of the connecting pipe away from the fixed box. This multi-functional multi-stage crushing device for quartz sand processing effectively handles the dust generated during the crushing process by incorporating a dust collection mechanism, preventing dust from spreading and being inhaled, thus avoiding health problems. However, a drawback is that when internal parts need maintenance, the narrow feed inlet makes maintenance somewhat inconvenient. Utility Model Content

The end of the pneumatic telescopic rod 401 is limited and mounted with a hinge connecting seat 402. The two hinge connecting seats 402 are fixedly mounted on the opening and closing plate 403. The bottom of the opening and closing plate 403 is fixedly mounted with a limiting rotating column 404.

[0027] By installing the convenient opening and closing component 4 on the device, when it is necessary to perform internal maintenance, the device can be opened and closed conveniently using the convenient opening and closing component 4, thus ensuring the convenience of maintenance during the work process.

[0028] The working box assembly 1 includes a crushing box 101. A feeding trough 102 is fixedly installed on the top of the crushing box 101, and the crushing box 101 is hexagonal. At the same time, sliding slots 104 are correspondingly opened on the bottom side of the outer walls on both sides of the crushing box 101. A stirring component 103 is correspondingly arranged inside the feeding trough 102. Quartz sand is fed in through the feeding trough 102 on the top of the crushing box 101 in the working box assembly 1. The stirring component 103 inside the feeding trough 102 can perform preliminary stirring of the quartz sand, so that the quartz sand enters the crushing box 101 evenly.

[0029] The crushing assembly 2 includes a crushing motor 201, which is fixedly installed on the outer wall of the crushing box 101 by a bracket. A rotating rod 202 is fixedly installed in the middle of the inside of the crushing motor 201, and a crushing wheel 203 is fixedly installed in the middle of the rotating rod 202. The crushing wheel 203 is correspondingly arranged inside the crushing box 101. The crushing motor 201 drives the rotating rod 202 and the crushing wheel 203 to rotate, so as to perform preliminary crushing of the quartz sand. The toothed wall 307 of the rotating wall assembly 3 cooperates with the crushing wheel 203 to form a multi-stage crushing space.

[0030] The rotating wall assembly 3 includes a pneumatic telescopic rod 301, which is connected to the bottom of the outer walls on both sides of the crushing box 101 via hinges. The end of the pneumatic telescopic rod 301 is fitted with a hinge mounting seat 302. The hinge mounting seats 302 on both sides are fixedly fitted with limit rotating rods 303. The limit rotating rods 303 are rotatably mounted on the connecting column 304. The inner walls at both ends of the connecting column 304 are fixedly fitted with connecting plates 305. The outer walls at the ends of the two connecting plates 305 are fixedly fitted with movable inner walls 306. The movable inner walls 306 are slidably mounted on the inner side of the inner wall of the crushing box 101. The inner wall of the movable inner walls 306 is fixedly fitted with toothed walls 307. The movement of the movable inner walls 306 is controlled by the pneumatic telescopic rod 301, thereby changing the size of the crushing space and achieving different degrees of crushing.

[0031] The limiting rotating column 404 is installed at the diagonal positions on both sides of the crushing box 101. The convenient opening and closing component 4 can control the opening and closing of the opening and closing plate 403, which facilitates equipment maintenance and quartz sand discharge.

[0032] The bottom of the toothed wall 307 is provided with a discharge port 3071.

[0033] This multi-stage crushing device for quartz sand processing mainly achieves multi-stage crushing of quartz sand through the mechanical crushing action of the crushing component 2, combined with the assistance of the rotating wall component 3 and the convenient opening and closing component 4. The crushing motor 201 drives the rotating rod 202 and the crushing wheel 203 to rotate, performing initial crushing of the quartz sand. The toothed wall 307 of the rotating wall component 3 cooperates with the crushing wheel 203 to form a multi-stage crushing space. The movement of the inner wall 306 is controlled by the pneumatic telescopic rod 301, changing the size of the crushing space and achieving different degrees of crushing. The convenient opening and closing component 4 controls the opening and closing of the opening and closing plate 403, facilitating equipment maintenance and quartz sand discharge. In the working process, quartz sand is fed into the feed trough 102 at the top of the crushing box 101 in the working box component 1. The stirring component 103 inside the inlet 102 can initially stir the quartz sand, so that the quartz sand enters the crushing box 101 evenly. The crushing motor 201 in the crushing component 2 starts, driving the rotating rod 202 and the crushing wheel 203 to rotate at high speed, and initially crushing the quartz sand that enters the crushing box 101. The pneumatic telescopic rod 301 of the rotating wall component 3 works, and through the hinge connecting seat 302, the limiting rotating rod 303, the connecting column 304 and the connecting plate 305, it drives the moving inner wall 306 and the toothed wall 307 to slide in a limited position on the inner side of the inner wall of the crushing box 101. The toothed wall 307 works in conjunction with the crushing wheel 203. The extension length of the pneumatic telescopic rod 301 can be adjusted as needed to change the size of the crushing space, further crushing the initially crushed quartz sand to achieve a multi-stage crushing effect. After crushing, the pneumatic telescopic rod 401 of the convenient opening and closing assembly 4 is activated, driving the opening and closing plate 403 to rotate around the limiting rotating column 404 through the hinge connecting seat 402. The crushed quartz sand is discharged from the discharge port 3071 at the bottom of the toothed wall 307. At the same time, opening the opening and closing plate 403 also facilitates cleaning and maintenance of the equipment. The opening and closing plate 403 is limited by the limiting rotating column 404 and installed at the diagonal positions on both sides of the crushing box 101 to ensure the stability of opening and closing. After discharge and maintenance are completed, the opening and closing plate 403 of the convenient opening and closing assembly 4 is closed, and the rotating wall assembly 3 is adjusted back to the initial position to prepare for the next quartz sand crushing operation.
