[0002] Quartz sand is a non-metallic mineral raw material with silica as its core component and quartz mineral as its main component. It has the characteristics of high hardness, strong chemical stability and high temperature resistance. It is a basic material with wide application in the industrial field. It is not a natural single form, but is formed into sandy materials of different particle sizes after quartz minerals such as quartzite, quartz sandstone and vein quartz are processed by crushing, grinding, screening and purification.

[0003] Currently, some quartz sand screening devices on the market can only achieve coarse grading of quartz sand and cannot reach the purity standard required for production in one go. Subsequent secondary or even multiple screening operations are required. Before each secondary screening, different specifications of sorting screens need to be manually changed. This operation will cause time loss and reduce work efficiency. To address this, we propose a multi-stage vibrating sorting screen for quartz sand. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 - Appendix Figure 3 A multi-stage vibrating sieve for quartz sand includes a protective shell 1 and a wedge block 2. The lower end of the protective shell 1 is fixedly installed with the upper end of the wedge block 2. A screening assembly 3 and a vibration assembly 4 are provided on the outside of the protective shell 1. The screening assembly 3 includes multiple screen plates 301, a U-shaped frame 302 and a fixing block 305. The left and right sides of the multiple screen plates 301 are slidably connected to the inside of the U-shaped frame 302. The multiple screen plates 301 are located inside the protective shell 1 and are arranged in a vertical parallel direction. The side of the U-shaped frame 302 away from the screen plates 301 is fixedly installed with one side wall of the protective shell 1. The rear side of the U-shaped frame 302 is fixedly installed with the bottom end of the protective shell 1, and the rear side of the screen plates 301 is in contact with the inside of the protective shell 1. The right side of the protective shell 1 is fixedly connected with the left side of the fixing block 305. A conveying block 306 is fixedly installed at the lower end of the fixing block 305.

[0016] Multiple sieve plates 301 are arranged vertically and parallel inside the protective shell 1, with the size of the holes in the sieve plates 301 arranged from top to bottom to facilitate the grading of quartz sand. The sieve plates 301, the protective shell 1, and the parts thereon are inclined to allow the quartz sand to fall downwards. The U-shaped frame 302 is slidably connected to the left and right sides of the multiple sieve plates 301 to keep the sieve plates 301 stable. A sieve frame is fixed to the sieve plate 301 itself, and the sieve frame slides inside the U-shaped frame 302. The interior of the frame 302 is in contact with the upper and lower sides of the screen frame without gaps, which facilitates the vertical movement of the screen plate 301. The fixing block 305 is connected to the protective shell 1 and the conveying block 306. The grading groove opened inside the fixing block 305 conveys the quartz sand screened by the screen plate 301 into the grading groove, and then into the conveying block 306. The conveying block 306 has an inclined angle, which facilitates the collection of the screened quartz sand during use and does not obstruct the normal operation of the following parts.

[0017] The bottom end of the conveying block 306 is provided with a conveying groove 307, and the upper end of the protective shell 1 is fixedly installed with a discharge pipe 303.

[0018] The number of conveying troughs 307 inside the conveying block 306 is equal to the number of sieve plates 301, and each conveying trough 307 is not connected to the others. They convey different sizes of quartz sand to each other. The conveying trough 307 is connected to the grading trough inside the fixing block 305, which facilitates the collection of different sizes of quartz sand. The discharge pipe 303 can convey quartz sand to the sieve plate 301 inside the protective shell 1, which facilitates the conveying of quartz sand by the discharge pipe 303. The discharge pipe 303 can be expanded or reduced to accommodate different sizes of quartz sand.

[0019] The front side of the protective shell 1 is detachably connected to a barrier plate 304. The front end of the U-shaped frame 302 and the sieve plate 301 are in contact with the rear side of the barrier plate 304, and the left side of the barrier plate 304 is detachably connected to the fixing block 305.

[0020] The barrier plate 304 is detachable inside the front of the protective shell 1. During use, it is convenient to block the quartz sand inside the protective shell 1, so that the quartz sand will not leak out. Since it is detachable, it is easy to remove the barrier plate 304 and replace the screen plate 301. The barrier plate 304 and the U-shaped frame 302 are in contact with the front of the screen plate 301, which facilitates the positioning of the U-shaped frame 302 and the screen plate 301.

[0021] Specifically, the barrier plate 304 is stably installed inside the front side of the protective shell 1, with its left side reliably connected to the fixing block 305, and in close contact with the U-shaped frame 302 and the front end of the screen plate 301 to prevent the quartz sand from leaking out and to limit the position of each component. Then, the quartz sand to be sorted is fed into the equipment through the discharge pipe 303 at the upper end of the protective shell 1. Because the protective shell 1 and screen plates 301 are inclined, the quartz sand can slide down the slope. During the process, it is classified by multiple sets of vertically parallel screen plates 301 with mesh sizes changing sequentially from top to bottom inside the protective shell 1. The screen plates 301 are connected to the screen frame and... The U-shaped frame 302 is slidably connected on both sides, and the interior of the U-shaped frame 302 is in seamless contact with the upper and lower sides of the screen frame, which can prevent the screen plate 301 from moving up and down and keep it stable. The graded quartz sand enters the corresponding grading groove inside the fixed block 305, and then is conveyed to the conveying block 306 connected to it. The conveying block 306 not only has an inclined angle for easy collection, but also has one more conveying groove 307 than the screen plate 301, which are not interconnected. It can receive quartz sand of different particle sizes and complete the discharge. When the screen plate 301 needs to be replaced, the barrier plate 304 can be removed for convenient operation.

[0022] Please see the appendix Figure 4 and attached Figure 5 The vibration assembly 4 includes two sets of vibration motors 401, a sliding block 404, a spring 407, and a support rod 410. Both sets of vibration motors 401 are fixedly connected to the right side of the wedge block 2. The lower four corners of the protective shell 1 are fixedly installed with the connecting rod 402. The lower end of the connecting rod 402 is fixedly installed with a fixing plate 403. The lower left and right sides of the fixing plate 403 are fixedly connected to the upper ends of the spring 407 and the telescopic rod 408. The spring 407 is sleeved on the outer circumference of the telescopic rod 408.

[0023] The vibration motor 401 is arranged horizontally and parallel to the right side of the wedge block 2, and is of equal size. It can drive the wedge block 2 and the parts on the wedge block 2 to vibrate. The connecting rod 402 is of the same size, which can enhance the support force. Then, under the action of the vibration motor 401, the connecting rod 402 drives the fixed plate 403 to vibrate, and squeezes and pulls the spring 407 and the telescopic rod 408, so that the vibration frequency can be more uniform.

[0024] Slide plates 406 are fixedly installed on both the front and rear sides of the fixed plate 403. Slide grooves 405 are provided on both the front and rear sides of the sliding block 404. The slide plates 406 are slidably connected to the inside of the slide grooves 405. The four sides of the fixed plate 403 are in contact with the inner sidewall of the sliding block 404.

[0025] The sliding plates 406 fixed on the front and rear sides of the fixed plate 403 are of equal size. The number of sliding grooves 405 opened on the sliding block 404 is equal to that of the sliding plate 406. The width of the sliding groove 405 facilitates the sliding of the sliding plate 406 inside the sliding groove 405. When the sliding plate 406 slides, it can limit the height of the fixed plate 403 and the parts on it.

[0026] A connecting plate 409 is fixedly installed at the lower end of the sliding block 404. The lower end of the connecting plate 409 is fixedly installed with the support rod 410. A support base plate 411 is fixedly installed at the lower end of the support rod 410.

[0027] The four sides of the connecting plate 409 are fixed inside the lower end of the sliding block 404, which helps to protect the parts on the upper end of the connecting plate 409 and extend the service life of the spring 407 and the telescopic rod 408. The support rod 410 and the support base plate 411 can provide support for the parts on the support rod 410 and prevent the overall device from moving due to vibration.

[0028] Specifically, the two sets of equally sized vibration motors 401 arranged horizontally and parallel to the right side of the wedge block 2 are activated, which drive the wedge block 2 and the protective shell 1 to vibrate. The four equally sized connecting rods 402 at the lower corners of the protective shell 1 then drive the fixed plate 403 to vibrate. The fixed plate 403 squeezes and pulls the lower spring 407 and the telescopic rod 408. The spring 407 is sleeved on the telescopic rod 408 to buffer the vibration force. The equally sized sliding plates 406 on the front and rear sides of the fixed plate 403 slide in the corresponding number of sliding grooves 405 inside the sliding block 404, limiting the height of the fixed plate 403 and the parts above it. The connecting plate 409 at the lower end of the sliding block 404 protects the parts above and extends the life of the spring 407 and the telescopic rod 408. The support rod 410 and the support base plate 411 provide support force to prevent the device from shifting due to vibration.

[0029] The working principle of this utility model is as follows: This utility model is a multi-stage vibrating sorting screen for quartz sand. First, the two sets of equally scaled vibrating motors 401 on the right side of the wedge block 2 are started. The vibrating motors 401 drive the wedge block 2 and the protective shell 1 fixed thereto to vibrate. The protective shell 1 transmits the vibration force to the fixed plate 403 through the four equally scaled connecting rods 402 at the lower end. The fixed plate 403 squeezes and pulls the spring 407 with the telescopic rod 408 sleeved at the lower end. The spring 407 buffers the vibration force. At the same time, the sliding plates 406 on the front and rear sides of the fixed plate 403 slide in the sliding groove 405 of the sliding block 404, limiting its height. 4. The device is stably supported by the connecting plate 409, the support rod 410 and the support base plate 411 to prevent displacement. The quartz sand to be sorted is fed into the protective shell 1 through the feed pipe 303 at the upper end. Because the protective shell 1 and the internal vertical parallel screen plate 301 with the mesh size changing from top to bottom are inclined, the quartz sand slides down the slope and is classified by multiple sets of screen plates 301 under the action of vibration. After classification, the quartz sand enters the fixed block 305 classification groove and is then conveyed to the conveying block 306 with an inclined angle and non-interconnected conveying grooves 307. Finally, it is discharged from the corresponding conveying groove 307. The detachable barrier plate 304 on the front side of the protective shell 1 prevents the quartz sand from leaking out.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
