Description

Technical Field

[0001] This invention relates to the field of quartz sand dewatering technology, specifically to a tank-type quartz sand dewatering device. Background Technology

[0002] Tank-type quartz sand dewatering equipment is a closed pressure filtration device specifically designed for the dewatering treatment of quartz sand (including natural quartz sand, artificial quartz sand, etc.). The core of it achieves efficient separation of solid particles and water in quartz sand through the synergistic effect of "pressurization inside the tank + retention by filter plates / filter cloth". It is widely used in quartz sand processing (such as photovoltaic sand, glass sand purification), building materials, mineral processing and other fields to reduce the moisture content of quartz sand (usually from 30%-50% to 10%-18%) to meet the process requirements of subsequent drying, storage or deep processing.

[0003] The core principle of tank-type quartz sand dewatering equipment is to inject quartz sand slurry (solid content usually 20%-30%) into the tank, pressurize it with a feed pump (0.2-0.6MPa) or pressurize it with air inside the tank (0.5-1.2MPa), forcing the water in the slurry to pass through the filter plate holes and filter cloth, forming filtrate which is discharged from the bottom of the tank; while the quartz sand particles are trapped by the filter cloth / filter plate, forming a dense filter cake inside the tank, and finally the dewatered quartz sand is discharged through the unloading mechanism (such as scraper, hydraulic pusher), completing the closed-loop process of "feeding-pressurized dewatering-unloading";

[0004] Current tank-type quartz sand dewatering equipment requires multiple sets of electric drive components to complete the entire process, resulting in a high basic cost for the entire equipment. Summary of the Invention

[0013] Preferably, a sixth sliding groove is provided at both ends of the inner wall of the main body of the device and on one side of the fixed plate. A matching sixth slider is slidably connected inside each of the two sets of sixth sliding grooves. A second toothed plate is fixedly connected between the two sets of sixth sliders, and a top plate is fixedly connected to the top of the second toothed plate.

[0014] Preferably, the filter plate has a third sliding groove inside, and a matching sandwich filter plate is slidably connected inside the third sliding groove. A first spring is fixedly connected to one side of the sandwich filter plate, and the other end of the first spring is fixedly connected to one side of the third sliding groove. A roller is rotatably connected to the other side of the sandwich filter plate.

[0015] Preferably, both sides of the filter plate are provided with transmission components for driving the scraper to scrape the dewatered quartz sand. The transmission component includes a first sliding groove opened at one end of the filter plate. A first slider and a second slider that match the first sliding groove are slidably connected inside the first sliding groove. A first gear located inside the first sliding groove is rotatably connected to one end of the filter plate. A first rack located above the first gear and meshing with the first gear is fixedly connected to one side of the first slider. A second rack located below the first gear and meshing with the first gear is fixedly connected to one side of the second slider.

[0016] Preferably, a second sliding groove is provided on one side of the top of the filter plate. There are two sets of the second sliding grooves.

[0020] Compared with the prior art, the present invention provides a tank-type quartz sand dewatering device with the following beneficial effects: After the device has finished filtering the quartz sand, the electric push rod is activated to retract. The fifth slider, which is fixedly connected to the output end of the electric push rod, will move upward along the fifth sliding groove. At the same time, the fixed rod, which is fixedly connected to the output end of the electric push rod, will drive the pressure plate to detach from the quartz sand on the filter plate. During this process, due to the downward pulling force of the second spring, the first toothed plate is in a fixed state relative to the second gear. When the electric push rod retracts until the fifth slider contacts the top of the fifth sliding groove, the electric push rod is continuously activated to retract, causing the pressure plate to move upward continuously. At the same time, the first toothed plate moves upward, and the second gear begins to rotate. At this time, the second spring begins to be stretched and tightened. The rotation of the second gear will cause the filter plate to rotate. The device operates by connecting the sandwiched filter plate inside the filter plate to the third sliding groove via a first spring, and a roller is rotatably connected to the other side. As the filter plate rotates, the sandwiched filter plate continuously slides downward against the inner wall of the device body and extends relative to the filter plate until it contacts the limiting plate, at which point the dewatered quartz sand can be unloaded. During the downward sliding of the sandwiched filter plate, the first slider moves, which in turn causes the first rack and second rack to move in opposite directions about the meshing first gear. That is, the first scraper and the second scraper move simultaneously in opposite directions and scrape the filter plate. In this design, the device uses only one set of electrical components to complete multiple actions of the quartz sand dewatering process, greatly reducing the use of electrical components and thus reducing the basic cost of the equipment.

[0023] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Example 1

[0025] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, a tank-type quartz sand dewatering device includes a device body 1. The device body 1 is equipped with a filter press assembly for dewatering quartz sand by filter press. The filter press assembly includes an electric push rod 2 installed on the top of the device body 1.

[0026] A fourth sliding groove 31 is formed on one side of the main body 1. A first toothed plate 32 that matches it is slidably connected inside the fourth sliding groove 31. A second spring 37 is fixedly connected to the bottom of the first toothed plate 32. The bottom end of the second spring 37 is fixedly connected to the bottom of the fourth sliding groove 31.

[0027] A fifth sliding groove 33 is formed at the top of the inside of the first toothed plate 32. A fifth slider 34 is slidably connected inside the fifth sliding groove 33. The top of the fifth slider 34 is fixedly connected to the output end of the electric push rod 2.

[0028] A fixed plate 36 is fixedly connected to one side of the fourth sliding groove 31. A first rotating shaft 16 located inside the fixed plate 36 is rotatably connected to the inner wall of the main body 1. A second gear 35 that meshes with the first toothed plate 32 is fixedly connected to the outer side of the first rotating shaft 16. The second gear 35 is a half gear. A filter plate 12 is fixedly connected to one side of the second gear 35. A movable groove 30 is opened on one side of the fixed plate 36.

[0029] A fixed rod 10 is fixedly connected to one side of the output end of the electric push rod 2. The fixed rod 10 passes through the movable groove 30. A pressure plate 11 that matches the filter plate 12 is fixedly connected to the bottom of one side of the fixed rod 10.

[0030] The filter plate 12 has a third sliding groove 28 inside, and a matching sandwich filter plate 17 is slidably connected inside the third sliding groove 28. A first spring 29 is fixedly connected to one side of the sandwich filter plate 17, and the other end of the first spring 29 is fixedly connected to one side of the third sliding groove 28. A roller 22 is rotatably connected to the other side of the sandwich filter plate 17.

[0031] In this embodiment, after the equipment has finished filtering the quartz sand, the electric push rod 2 is activated to retract. The fifth slider 34, which is fixedly connected to the output end of the electric push rod 2, will move upward along the fifth sliding groove 33. At the same time, the fixed rod 10, which is fixedly connected to the output end of the electric push rod 2, will drive the pressure plate 11 to detach from the quartz sand on the filter plate 12. During this process, due to the downward pulling force of the second spring 37, the first toothed plate 32 is in a fixed state relative to the second gear 35. Since the fixed rod 10 passes through the movable groove 30, a sealing expansion pad is set at the connection position between the fixed rod 10 and the movable groove 30, which can achieve a sealing effect and avoid hindering the movement of the fixed rod 10. When the electric push rod 2 retracts to the point where the fifth slider 34 contacts the fifth sliding groove... At the top of 33, the electric push rod 2 is continuously activated to retract, causing the pressure plate 11 to move upward continuously. At the same time, the first toothed plate 32 moves upward, and the second gear 35 starts to rotate. At this time, the second spring 37 begins to be stretched and tightened. The rotation of the second gear 35 will cause the filter plate 12 to rotate. Since the sandwich filter plate 17 inside the filter plate 12 is connected to the third sliding groove 28 through the first spring 29, the first spring 29 is in a compressed state, and the other side of the sandwich filter plate 17 is rotatably connected to the roller 22, so that during the rotation of the filter plate 12, the sandwich filter plate 17 continuously slides downward against the inner wall of the device body 1 and continuously extends relative to the filter plate 12, so that the dewatered quartz sand can be unloaded.

[0032] Example 2

[0033] Please refer to Figure 2 and Figure 6 As shown, a second rotating shaft 41 located inside the fixed plate 36 is rotatably connected to the inner wall of the main body 1 of the device, and a third gear 40 that meshes with the first gear plate 32 is fixedly connected to the outer side of the second rotating shaft 41.

[0034] The inner walls of the main body 1 are provided with a sixth sliding groove 38 at both ends and on one side of the fixed plate 36. The interior of each of the two sets of sixth sliding grooves 38 is slidably connected with a matching sixth slider 39. A second toothed plate 42 is fixedly connected between the two sets of sixth sliders 39. A top plate is fixedly connected to the top of the second toothed plate 42.

[0035] In this embodiment, when the equipment needs to filter quartz sand, the electric push rod 2 is extended, causing the fifth slider 34 to move to the bottom of the fifth sliding groove 33. The electric push rod 2 continues to extend, which pushes the first toothed plate 32 to move downward along the fourth sliding groove 31. During the downward movement of the first toothed plate 32, the second gear 35 and the third gear 40 meshing with it will rotate simultaneously. During the rotation of the second gear 35, the second toothed plate 42 will be driven to move upward, and the sixth sliders 39 on both sides will move in the sixth sliding groove 38. When the second gear 35 rotates to the horizontal position of the filter plate 12, the second toothed plate 42 will drive the top plate to contact the bottom of the filter plate 12. Therefore, when the equipment starts to filter, the extension of the electric push rod 2 will cause the top plate to have an upward tendency, thereby supporting the filter plate 12 to withstand the pressure of filtration.

[0036] Example 3

[0037] Please refer to Figure 3 and Figure 4 As shown, both sides of the filter plate 12 are provided with transmission components for driving the scraper to scrape the dewatered quartz sand. The transmission components include a first sliding groove 24 opened at one end of the filter plate 12. A first slider 20 and a second slider 21 that match the first sliding groove 24 are slidably connected inside the first sliding groove 24. A first gear 23 located inside the first sliding groove 24 is rotatably connected to one end of the filter plate 12. A first rack 26 located above the first gear 23 and meshing with the first gear 23 is fixedly connected to one side of the first slider 20. A second rack 27 located below the first gear 23 and meshing with the first gear 23 is fixedly connected to one side of the second slider 21.

[0038] A second sliding groove 25 is provided on one side of the top of the filter plate 12. There are two sets of the second sliding groove 25. The two sets of first sliders 20 and the two sets of second sliders 21 pass through the two sets of second sliding grooves 25 respectively. A first scraper 18 is fixedly connected between the two sets of first sliders 20, and a second scraper 19 is fixedly connected between the two sets of second sliders 21.

[0039] In this embodiment, when the second gear 35 rotates and drives the filter plate 12 to tilt downward, the sandwich filter plate 17 continues to slide downward against the inner wall of the device body 1. During this process, the first sliders 20 on both sides of the sandwich filter plate 17 will move in the first sliding groove 24, and at the same time, the first rack 26 will pull the first gear 23 to rotate. The first gear 23 will then cause the second rack 27 to move, that is, to move in the opposite direction to the first rack 26. Therefore, the first scraper 18 on the two sets of first sliders 20 and the second scraper 19 on the two sets of second sliders 21 will move relative to each other during the whole process, and at the same time scrape the quartz sand on the top of the filter plate 12.

[0040] Example 4

[0041] Please refer to Figure 1and Figure 2 As shown, the device body 1 has a water outlet at the bottom, a rotary motor 9 is installed on one side of the water outlet, the output section of the rotary motor 9 is fixedly connected to a rotating door 8 that matches the water outlet, and a sealing ring is fixedly connected to the top edge of the rotating door 8.

[0042] A device bracket 7 is fixedly connected to the outside of the device body 1. A vacuum pump 6 connected to the inside of the device body 1 is installed on the front surface of the device body 1. A feed inlet 3 is opened on one side of the device body 1. An electromagnetic valve is installed inside the feed inlet 3.

[0043] A discharge port 4 is provided on one side of the main body 1 and below the inlet 3. An electromagnetic slide 13 is provided on the top of the discharge port 4. An electromagnetic slider 14 is slidably connected inside the electromagnetic slide 13. A closed door matching the discharge port 4 is fixedly connected to the bottom of the electromagnetic slider 14. A limit plate 15 is fixedly connected to one side of the discharge port 4, and a discharge ladder 5 is fixedly connected to the other side of the discharge port 4.

[0044] In this embodiment, when the main body 1 of the device needs to discharge the water removed by the quartz sand, the rotary motor 9 is started, which opens the rotating door 8 to separate from the outlet, and then the wastewater flows out. Since the top edge of the rotating door 8 has a sealing ring, the outlet is sealed when closed. The user can control the feeding and closing of the feed port 3 by controlling the electromagnetic valve. When the second gear 35 rotates and drives the filter plate 12 to tilt downward, the limiting plate 15 can limit the filter plate 12, thereby positioning the filter plate 12 at the outlet. The user can control the discharge and closing of the outlet 4 by controlling the electromagnetic slider 14 to move in the electromagnetic chute 13. When the main body 1 of the device is in a closed state, the vacuum pump 6 is started to pressurize, which can accelerate the dewatering speed of the quartz sand. When the vacuum pump 6 is started to pressurize, the quartz sand in the filter plate 12 can be blown in the opposite direction to promote the unloading of the quartz sand.

[0045] The working principle and usage process of this device are as follows: After the equipment has finished filtering the quartz sand, the electric push rod 2 is activated to retract. The fifth slider 34, which is fixedly connected to the output end of the electric push rod 2, will move upward along the fifth sliding groove 33. At the same time, the fixed rod 10, which is fixedly connected to the output end of the electric push rod 2, will drive the pressure plate 11 to detach from the quartz sand on the filter plate 12. During this process, due to the downward pulling force of the second spring 37, the first toothed plate 32 is in a fixed state relative to the second gear 35. When the electric push rod 2 retracts until the fifth slider 34 contacts the top of the fifth sliding groove 33, the electric push rod 2 is continuously activated to retract, causing the pressure plate 11 to move upward continuously. At the same time, the first toothed plate 32 moves upward, and the second gear 35 begins to rotate. At this time, the second spring 37 begins to be stretched and tightened. The rotation of the second gear 35 will cause the filter plate 12 to rotate. Due to the internal... The sandwich filter plate 17 is connected to the third sliding groove 28 by the first spring 29, and a roller 22 is rotatably connected to the other side. Therefore, during the rotation of the filter plate 12, the sandwich filter plate 17 continuously slides downward against the inner wall of the device body 1 and extends relative to the filter plate 12 until it contacts the limiting plate 15, at which point the dewatered quartz sand can be unloaded. During the downward sliding of the sandwich filter plate 17, the first slider 20 moves, which in turn causes the first rack 26 and the second rack 27 to move in opposite directions about the meshing first gear 23. That is, the first scraper 18 and the second scraper 19 move in opposite directions at the same time and scrape the filter plate 12. In this design, the device uses only one set of electrical components to complete multiple actions of the quartz sand dewatering process, which greatly reduces the use of electrical components and thus reduces the basic cost of the equipment.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
