Description

Technical Field

[0001] This utility model belongs to the field of quartz sand technology, specifically relating to a quartz sand washing and dewatering screen. Background Technology

[0002] Quartz sand is quartz particles processed from quartz stone through crushing, screening, and other processes. Its main mineral component is silicon dioxide (SiO2), an important non-metallic mineral. Quartz sand is typically milky white or colorless and translucent with a greasy luster. It has a Mohs hardness of 7, indicating high hardness and wear resistance. Its density is approximately 2.65 g / cm³, although the bulk density varies depending on the particle size. The particles exhibit diverse shapes, generally with conchoidal or uneven fractures and no cleavage. Quartz sand is chemically stable, insoluble in acids (but slightly soluble in KOH solution), and has a melting point as high as 1750℃, exhibiting high refractory properties. Currently, after washing, quartz sand is drained on washing equipment to remove water stains adhering to its surface. However, because the quartz sand is in a static state, the draining effect is poor, and the sand tends to clump, affecting the draining efficiency. Therefore, the inventors have proposed a quartz sand washing and dewatering screen. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quartz sand washing and dewatering screen, which aims to solve the problems of poor drainage effect and easy agglomeration of quartz sand due to the static state of the quartz sand.

[0005] (2) Technical solution

[0006] To address the aforementioned technical problems, this utility model provides a quartz sand washing and dewatering screen, comprising a base box, a movable frame, a supporting mesh plate, and an air outlet screen. The movable frame is horizontally positioned above the base box and is slidably installed with the base box. The movable frame has a hollow structure, and the supporting mesh plate is horizontally fixed inside. Driving blocks are respectively provided on the outer walls of both sides of the movable frame. A connector is fixed to the bottom of each driving block, and a telescopic cylinder is fixedly connected to the connector. The telescopic cylinder is adapted to the outer wall of the base box. An air outlet screen is installed on the inner side wall of the movable frame, and the air outlet screen is horizontally installed along the length of the movable frame. Thanks to the movable frame, the washed quartz sand can be supported. During the dewatering process, as the movable frame continuously swings, the quartz sand can be continuously agitated, preventing clumping and improving the dewatering effect.

[0007] Preferably, the movable frame has an internal air storage chamber, and the outer wall of the movable frame has an installation hole that communicates with the air storage chamber.

[0008] Preferably, multiple sets of mounting holes are spaced apart along the outer wall of the movable frame, and transmission pipes are installed on each set of mounting holes.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention benefits from the design of a movable frame, which can support the washed quartz sand. During the draining process, the quartz sand is constantly turned over as the movable frame swings, preventing clumping and improving the dehydration effect. It is highly practical. Furthermore, during the dehydration process, an air storage chamber is provided on the inner wall of the movable frame, which can transport hot air towards the quartz sand and blow air onto the quartz sand on the supporting mesh plate. The quartz sand can better contact the heat during the shaking process, achieving rapid dehydration. It is highly practical and can be widely promoted. Attached Figure Description

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.

[0023] This specific embodiment is a quartz sand washing and dewatering screen, the structural schematic diagram of which is shown below. Figure 1 As shown, the system includes a base box 1, a movable frame 10, a supporting mesh plate 9, and an air outlet mesh 8. The movable frame 10 is horizontally positioned above the base box 1 and is slidably installed with the base box 1. The movable frame 10 has a hollow structure, and the supporting mesh plate 9 is horizontally fixed inside. Drive blocks 5 are respectively provided on the outer walls of both sides of the movable frame 10. A connector 4 is fixed to the bottom of the drive block 5, and a telescopic cylinder 2 is fixedly connected to the connector 4. The telescopic cylinder 2 is adapted to be installed on the outer wall of the base box 1. An air outlet mesh 8 is installed on the inner side wall of the movable frame 10, and the air outlet mesh 8 is horizontally installed along the length of the movable frame 10. A fixing seat 3 is fixedly installed on the outside of the telescopic cylinder 2, and the fixing seat 3 is fixedly connected to the base box 1.

[0024] Reference Figure 2 The bottom of the bottom box 1 is provided with a discharge pipe 7. The interior of the bottom box 1 is provided with a diversion plate 11, which is inclined and the lower end faces the discharge pipe 7.

[0025] Reference Figure 3 An inner sliding groove 12 is horizontally opened on the inner side wall of the bottom box 1, and a bottom block 13 is protruding from the bottom of the bottom box 1. The bottom block 13 is slidably installed with the inner sliding groove 12.

[0026] Reference Figure 4 The movable frame 10 has an internal air storage chamber 15, and mounting holes 14 are provided on the outer wall of the movable frame 10, which communicate with the air storage chamber 15. Multiple sets of mounting holes 14 are spaced apart along the outer wall of the movable frame 10, and transmission pipes 6 are installed on each set of mounting holes 14. Hot air is introduced into the air storage chamber 15 through the transmission pipes 6, and then heat is released at the air outlet 8 to blow air onto the quartz sand on the supporting mesh plate 9.

[0027] Working principle: When in use, the cleaned quartz sand is first poured into the bearing mesh plate 9. Then, the telescopic cylinder 2 is started. As the telescopic cylinder 2 extends and retracts, the drive block 5 drives the moving frame 10 to move synchronously. The moving frame 10 slides on the upper surface of the bottom box 1. The moving frame 10 moves back and forth under force, shaking the quartz sand continuously. The quartz sand is scattered. Then, hot air is introduced into the air storage chamber 15 through the transmission pipe 6. Then, the heat is released at the air outlet 8 to blow air onto the quartz sand on the bearing mesh plate 9. During the shaking process, the quartz sand comes into contact with heat and is quickly dehydrated. The drained water flows down from the bearing mesh plate 9 and is discharged through the discharge pipe 7 through the guide plate 11.

[0028] During the back-and-forth swinging of the moving frame 10, the bottom block 13 slides along the inner groove 12, providing support for the moving frame 10 and making its sliding smoother.
