[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows workers to pre-feed quartz sand into the feed hopper using an external conveying device. The separate guide plates and buffer pads on their inner sides assist the quartz sand in extending its flow path and duration along the layered guide, achieving uniform feeding and preventing material accumulation on the polyurethane screen.

Detailed Implementation

[0024] 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.

[0025] This specific embodiment is a quartz sand dewatering screen, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the system includes a base 1, a dewatering screen frame 3 mounted on top of the base 1, and a vibrating screen mechanism 2 mounted on top of the base 1 and at its four contact points with the dewatering screen frame 3. A polyurethane screen 4 is fixedly mounted in the middle of the dewatering screen frame 3, and a material leveling and anti-piling mechanism 5 is jointly mounted on one side of the middle of the dewatering screen frame 3 and one side of the base 1. The vibrating screen mechanism 2 includes mounting blocks 21, which are distributed above the four sides of the base 1. Metal spiral composite springs 22 are mounted on top of the mounting blocks 21, and the dewatering screen frame 3 is fixedly mounted on top of the multiple metal spiral composite springs 22. A fixing frame 23 is fixedly mounted in the middle of the upper part of the dewatering screen frame 3, and the fixing frame 23 is screwed on top of the fixing frame 23. The screen is equipped with a mounting frame 24, and a vibration motor 25 is fixed above the mounting frame 24. When the quartz sand is evenly spread on the polyurethane screen 4 using the material equalization and anti-pilling mechanism 5, the two sets of vibration motors 25 can be started to vibrate the dewatering screen frame 3. At this time, the four sets of metal spiral composite springs 22 connected between the dewatering screen frame 3 and its base 1 can absorb and buffer the vibration and impact generated during the operation of the dewatering screen by using the elastic deformation of the springs, so that the polyurethane screen 4 can stably perform vibration screening of quartz sand. The polyurethane screen 4 has good wear resistance, corrosion resistance, high elasticity and flexibility, which can effectively prevent materials from adhering to the screen surface, thereby ensuring dewatering efficiency.

[0026] The material leveling and anti-piling mechanism 5 includes a material leveling component 51, which is fixedly installed on one side of the base 1. The material leveling component 51 includes a feeding hopper frame 511, which is located above one side of the dewatering screen frame 3. A welded fixing frame 512 is fixedly installed below the dewatering screen frame 3. The two ends of the welded fixing frame 512 are welded and fixedly connected to the feeding hopper frame 511 and the base 1, respectively. The feeding hopper frame 511 has staggered guide plates 513 inside, and buffer pads 514 are provided above the multiple guide plates 513. 513 are arranged at equal intervals in a staggered manner along the inside of the feed hopper frame 511, and buffer pads 514 are fixed at equal intervals on the surface of the guide plate 513. An anti-stacking component 52 is fixedly installed on one side of the middle part of the dewatering screen frame 3. The anti-stacking component 52 includes a fixing frame 521, which is fixed to one side of the middle part of the dewatering screen frame 3. An internal groove 522 is opened in the middle of the fixing frame 521, and guide frames 523 are arranged on both sides of the middle part of the internal groove 522. A scraper plate 524 is slidably installed in the middle of the guide frame 523, and the middle part of the guide frame 523 and The scraper plate 524 has screw grooves 525 on both sides, and a bolt rod 526 is screwed into the middle of one of the screw grooves 525. The scraper plate 524 and the guide frame 523 inside the inner groove 522 form a movable guide connection. The operator uses an external conveying device to transport the quartz sand material into the feed hopper frame 511 in advance. At this time, the guide plates 513 and the buffer pads 514 on the inner side of the plates can help the quartz sand extend its own flow path and time along the layered guide, thereby achieving the effect of uniform feeding and avoiding large-scale feeding. Some materials fall onto the polyurethane screen 4 at the same time, causing material accumulation. Meanwhile, since a scraper plate 524 is provided in the feeding area on one side of the dewatering screen frame 3, even if there is a certain height difference in the materials, the materials can naturally pass through the area below the scraper plate 524 when they move with vibration, achieving a natural scraping effect. This allows the quartz sand to be evenly spread on the screen surface, improving the dewatering effect. Subsequently, personnel can also adjust the height of the scraper plate 524 appropriately using the screw groove 525 and bolt rod 526 according to the different sizes and batches of quartz sand, thereby improving the adaptability.

[0027] Working principle: The staff uses an external conveying device to guide the quartz sand material into the feed hopper frame 511. At this time, the guide plates 513 and the buffer pads 514 on the inner side of the plates help the quartz sand to extend its own flow path and time along the layered guide, so as to achieve the effect of uniform feeding and avoid the accumulation of material on the polyurethane screen 4 at the same time. At the same time, since there is a scraper plate 524 in the feeding area on one side of the dewatering screen frame 3, even if there is a certain height difference in the material, the material can naturally pass through the area under the scraper plate 524 when it moves with vibration, so as to achieve a natural scraping effect. This makes the quartz sand evenly spread on the screen surface and improves the dewatering effect. The staff can also adjust the height of the scraper plate 524 appropriately according to the size and batch of quartz sand using the screw groove 525 and bolt rod 526 to improve the adaptability.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

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.
