Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz sand processing technology, specifically a quartz sand filtration and cleaning device. Background Technology
[0002] Quartz sand is quartz particles produced by crushing and screening quartz stone. Its main component is silicon dioxide (SiO2). It is a non-metallic mineral with stable chemical properties, insoluble in acids (but slightly soluble in KOH solution), and has a melting point as high as 1750℃. It also has high refractory properties. Quartz sand is usually milky white or colorless and translucent with a greasy luster. It has a Mohs hardness of 7 and a density of approximately 2.65 g / cm³. Quartz sand has wide applications in many industrial fields, including glass manufacturing, ceramics and refractory materials, metallurgy, construction, and chemicals. Especially in the semiconductor and photovoltaic industries, high-purity quartz sand is a key material for manufacturing core components such as integrated circuits and solar panels.
[0003] Quartz sand often needs to be cleaned before use. The purpose of cleaning is to remove small particles of impurities such as yellow skin, water rust, and dust from the surface of the quartz sand. However, most existing quartz sand does not undergo efficient filtration before cleaning. This makes it difficult to effectively remove some large particles of impurities mixed in during the processing of quartz sand during subsequent cleaning, and it can easily cause blockage when the quartz sand is discharged, affecting the cleaning efficiency of the quartz sand. Utility Model Content
[0004] The purpose of this invention is to provide a quartz sand filtration and cleaning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A quartz sand filtration and cleaning device includes a cleaning tank and a filter tank. An agitator shaft is installed inside the cleaning tank, with both ends of the shaft rotating via waterproof bearings embedded in the cleaning tank. An agitator rod is mounted on the agitator shaft, and one end of the shaft is directly connected to the output shaft of an agitator motor mounted on the outer wall of the cleaning tank. A filter tank is located on one side of the cleaning tank, and a first filter screen and a second filter screen are installed sequentially from top to bottom inside the filter tank. A constriction section is installed at the bottom of the filter tank, and a horizontal screw conveyor is installed at the bottom of the constriction section. A vertical screw conveyor is installed at the outlet of the horizontal screw conveyor, with the outlet of the vertical screw conveyor located directly above the cleaning tank. A vibrating motor is installed at the bottom of the filter tank, and a water outlet pipe is installed at the bottom of the cleaning tank. A discharge pipe is installed at an angle on one side of the water outlet pipe, and a separation screen is installed inside the water outlet pipe.
[0007] As a further embodiment of this invention: the stirring rods are staggered on the stirring shaft, and the degree of misalignment between two adjacent stirring rods is 90°.
[0008] As a further improvement of this utility model, water passage holes are evenly formed on the stirring rod.
[0009] As a further embodiment of this utility model: the first filter screen and the second filter screen are installed in the filter box at an inclination in opposite directions. The front and rear walls of the filter box are respectively provided with discharge ports that connect to the lower end of the second filter screen and the lower end of the first filter screen. A guide plate is installed outside the discharge port.
[0010] As a further improvement of this utility model: the separation net is inclined at the same angle as the discharge pipe, and a discharge valve and a water valve are respectively installed on the discharge pipe and the water discharge pipe.
[0011] As a further improvement of this utility model, the bottom of the cleaning tank is equipped with four cleaning tank support legs.
[0012] As a further improvement of this utility model: the bottom of the filter box is provided with four filter box support legs, and springs are installed between the filter box support legs and the filter box.
[0013] As a further improvement of this utility model: the mesh size of the first filter screen and the second filter screen decreases sequentially and is both larger than that of the quartz sand, while the mesh size of the separating screen is smaller than that of the quartz sand.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model, by setting up a filter box and a washing box, can filter out large particles of impurities mixed in with the quartz sand, preventing the quartz sand from having too many impurities during washing, which would affect the quality of the quartz sand. Furthermore, filtering before washing can prevent the quartz sand from clogging when it is discharged.
[0016] 2. This utility model, by setting up a discharge pipe, a water outlet pipe and a separation screen, can effectively separate the washed mud and water from the quartz sand. The quartz sand is discharged through the discharge pipe, while the mud and water are discharged through the water outlet pipe after passing through the separation screen. This can make the quartz sand separation more thorough, thereby reducing the difficulty of subsequent processing of the quartz sand. Attached Figure Description

[0021] 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.
[0022] Please see Figure 1-3 In this embodiment of the utility model, a quartz sand filtration and cleaning device includes a cleaning box 1 and a filter box 8. Four cleaning box support legs 2 are installed at the bottom of the cleaning box 1. An agitator shaft 3 is provided inside the cleaning box 1. Both ends of the agitator shaft 3 rotate with waterproof bearings 4 embedded in the cleaning box 1. An agitator rod 6 is installed on the agitator shaft 3. One end of the agitator shaft 3 is directly connected to the output shaft of an agitator motor 5 installed on the outer wall of the cleaning box 1.
[0023] The stirring rods 6 are staggered on the stirring shaft 3, and the stagger degree between two adjacent stirring rods 6 is 90°. This design allows for as many stirring rods 6 as possible to be arranged on the stirring shaft 3, thereby improving stirring efficiency.
[0024] The stirring rod 6 has water passage holes evenly distributed on it. The water passage holes can reduce the resistance encountered by the stirring rod 6 during rotation, thereby reducing the load on the stirring motor 5 during operation and achieving energy saving.
[0025] A water outlet pipe 18 is installed at the bottom of the cleaning tank 1, and a discharge pipe 17 is installed at an angle on one side of the water outlet pipe 18.
[0026] A separation screen 21 is installed inside the water outlet pipe 18. The separation screen 21 is inclined at the same angle as the discharge pipe 17. The mesh size of the separation screen 21 is smaller than that of the quartz sand. A discharge valve 19 and a water outlet valve 20 are installed on the discharge pipe 17 and the water outlet pipe 18, respectively.
[0027] Please see Figure 1 A filter box 8 is installed on one side of the cleaning tank 1. The first filter screen 11 and the second filter screen 12 are installed in the filter box 8 from top to bottom. Four filter box support legs 15 are installed at the bottom of the filter box 8. Springs 16 are installed between the filter box support legs 15 and the filter box 8. The springs 16 can effectively absorb and disperse the impact force generated by the filter screen during operation, reduce the vibration and noise of the equipment, and thus protect the equipment structure from damage. A constriction section 9 is installed at the bottom of the filter box 8. The constriction section 9 is used to guide the quartz sand toward the horizontal screw conveyor 10. The horizontal screw conveyor 10 is installed at the bottom of the constriction section 9. A vertical screw conveyor 7 is installed on the discharge port of the horizontal screw conveyor 10. The discharge port of the vertical screw conveyor 7 is located directly above the cleaning tank 1. A vibration motor 14 is installed at the bottom of the filter box 8.
[0028] The first filter screen 11 and the second filter screen 12 are installed in the filter box 8 at an angle to the opposite direction. The front and rear walls of the filter box 8 are respectively provided with discharge ports 22 that are connected to the lower end of the second filter screen 12 and the lower end of the first filter screen 11. A guide plate 13 is installed outside the discharge port 22. The guide plate 13 can allow the impurities discharged from the discharge port 22 to be discharged further away, preventing them from accumulating around the filter box 8.
[0029] The mesh size of the first filter screen 11 and the second filter screen 12 decreases sequentially and is larger than that of the quartz sand.
[0030] The filter box 8 of this utility model can also screen some quartz sand that is obviously too large (not completely crushed), thereby ensuring that the particle size of the quartz sand is more uniform and the cleaning quality is higher.
[0031] The working principle of this utility model is as follows:
[0032] In use, first pour the quartz sand into the filter box 8. When the quartz sand passes through the first filter screen 11 and the second filter screen 12, large particles of impurities are intercepted by the first filter screen 11 and the second filter screen 12 and discharged from the discharge port 22 under the drive of the vibrating motor 14. The quartz sand then enters the bottom of the filter box 8 and is continuously transported to the cleaning box 1 by the horizontal screw conveyor 10 and the vertical screw conveyor 7. In the cleaning box 1, the stirring motor 5 drives the stirring rod 6 to rotate through the stirring shaft 3 to turn the quartz sand, making the quartz sand cleaner. After cleaning, first open the water outlet valve 20 and then open the material outlet valve 19. The mud and water in the cleaning box 1 will be discharged directly from the water outlet pipe 18, and the quartz sand will be intercepted by the separation screen 21 in the water outlet pipe 18 and discharged from the material outlet pipe 17.
[0033] Although the present invention 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 invention should be included within the protection scope of the present invention.
