Description

Technical Field

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

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand needs to be washed during processing to obtain high-purity quartz sand. High-purity quartz sand is the material basis for high-end products in the silicon industry and plays an important role in strategic emerging industries such as new materials and new energy. It is one of the irreplaceable raw materials for modern industry and national defense. After washing, in order to reduce the moisture content of the quartz sand and ensure its quality and applicability, it needs to be dehydrated.

[0003] Currently, during the dehydration process, moisture is difficult to drain from the contact points where quartz sand accumulates, easily leading to excessive localized moisture buildup or uneven wetting, thus reducing the dehydration effect. Furthermore, the poor gas flow within the dehydration tank during dehydration fails to effectively remove moisture adhering to the quartz sand surface, further reducing dehydration efficiency. Therefore, a tank-type quartz sand dehydration device is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art that easily lead to excessive local accumulation of moisture or uneven drying and wetting, which reduces the dehydration effect; and the poor gas flow effect in the dehydration tank, which cannot effectively remove the moisture attached to the surface of the quartz sand, resulting in reduced dehydration efficiency. Therefore, a tank-type quartz sand dehydration device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tank-type quartz sand dewatering device includes a dewatering tank, which further includes: a retractable drain plate, the two ends of which are rotatably connected to both sides of the inner wall of the dewatering tank, and a lifting part for driving the drain plate to flip up and down is provided inside the dewatering tank; an air extraction box fixed to the inner wall of the dewatering tank, a sealing plate fixedly connected to the top of the inner cavity of the dewatering tank, a pressure accumulator formed between the sealing plate and the top of the inner cavity of the dewatering tank, a pressure extraction part for extracting airflow from the bottom cavity of the drain plate and filling the pressure accumulator, and pressure relief parts for discharging airflow from the pressure accumulator on both sides of the sealing plate.

Three sets of air pressure grooves are respectively opened between the bottom and top cavities of the air extraction box. An air pressure plate is slidably connected in the air pressure groove. A first spring is fixedly connected between the top of the air pressure plate and the air pressure groove. The air pressure plate and the first magnetic plate are magnetically repelled. The side wall of the air pressure groove is fixed and connected to an air extraction pipe. The other end of the air extraction pipe is connected to the bottom cavity of the dehydration tank. The side wall of the top cavity of the air extraction box is fixed and connected to an air inflation pipe. The other end of the air inflation pipe is connected to the inner cavity of the pressure accumulator. A one-way valve is provided in both the air extraction pipe and the air inflation pipe.

[0012] Furthermore, the inner cavity of the hinge shaft is provided with vibration grooves on both sides, and a guide slide rod is fixedly connected between the middle of the two vibration grooves. A striking sleeve is fixedly connected at equal intervals on the inner wall of the vibration groove. A striking block is slidably connected in the striking sleeve. A magnetic ring is slidably connected on the guide slide rod. A second spring is fixedly connected between the side wall of the magnetic ring and the inner wall of the vibration groove. The magnetic ring is magnetically connected to the striking block. A first pull rope is fixedly connected between the side walls of the two magnetic rings. A sealing tube is fixedly connected to the top of the air pressure plate located in the middle air pressure groove. The sealing tube passes upward through the air extraction box and is slidably connected to it in a sealing manner. A second pull rope is fixedly connected to the top of the air pressure plate.

[0013] Furthermore, the magnetic ring includes a first magnetic ring and a second magnetic ring, wherein the first magnetic ring is magnetically attracted to the striking block, and the second magnetic ring is magnetically repelled by the striking block.

[0014] To achieve rapid dehydration, preferably, the pressure relief section includes two sets of pressure relief seats, which are respectively fixed on both sides of the sealing plate. Each pressure relief seat has a pressure relief groove and a trigger groove on both sides of its inner cavity. The bottom ends of both the pressure relief groove and the trigger groove are connected to the upper cavity of the dehydration tank.

[0016] Compared with the prior art, the present invention provides a tank-type quartz sand dewatering device, which has the following beneficial effects:

[0017] 1. This tank-type quartz sand dewatering equipment uses a threaded sleeve that moves back and forth along a lifting screw. Combined with a hinged shaft, a drain sleeve, a drain telescopic plate, and a lifting plate, it agitates the quartz sand, ensuring even distribution within the dewatering tank and preventing excessive moisture accumulation or uneven drying. This improves the overall dewatering effect and alters the spacing between the quartz sand particles, making it easier for water to drain under gravity, further enhancing the dewatering efficiency.

[0018] 2. This tank-type quartz sand dewatering equipment utilizes the repulsive action between the first magnetic plate and the air pressure plate, along with the setting of the first spring, to continuously draw gas from the bottom of the dewatering tank during the dewatering process. This reduces the air pressure at the bottom of the dewatering tank, causing the gas in the upper cavity of the dewatering tank to move towards the bottom cavity, thereby removing the moisture carried on the surface of the quartz sand. Combined with the flipping action of the drain sleeve plate and the drain telescopic plate, this effectively accelerates the dewatering efficiency of the quartz sand.

[0019] 3. This tank-type quartz sand dewatering equipment continuously draws gas from the bottom of the dewatering tank into the accumulator chamber. When the threaded sleeve moves to the top, the pressure relief plate, pressure relief hole, and pressure relief hole are used to quickly spray the accumulated high-pressure gas downwards. This allows the moisture on the surface of the quartz sand to be carried away by the fast-flowing airflow, further accelerating the dewatering efficiency of the quartz sand.

[0020] 4. This tank-type quartz sand dewatering equipment, through the up-and-down movement of the air pressure plate, in conjunction with the setting of the first pull rope, the second pull rope, the first magnetic ring, the second magnetic ring and the striking block, continuously generates an impact and vibration effect in the hinge shaft during the dewatering process, thereby causing the water attached to the surface of the quartz sand to be shaken off quickly and effectively improving the dewatering efficiency of the quartz sand.

[0034] Example:

[0035] Reference Figures 1-10A tank-type quartz sand dewatering device includes a dewatering tank 1, and further includes: a retractable drain plate 2, the two ends of which are rotatably connected to the two sides of the inner wall of the dewatering tank 1, and a lifting part for driving the drain plate 2 to flip up and down is provided inside the dewatering tank 1; an air extraction box 3 fixed to the inner wall of the dewatering tank 1, a sealing plate 4 fixedly connected to the top of the inner cavity of the dewatering tank 1, a pressure accumulator 41 formed between the sealing plate 4 and the top of the inner cavity of the dewatering tank 1, a pressure accumulator 3 provided inside the air extraction box 3 for extracting airflow from the bottom cavity of the drain plate 2 and filling the pressure accumulator 41, and pressure relief parts for discharging airflow from the pressure accumulator 41 are provided on both sides of the sealing plate 4.

[0036] Reference Figure 2 , Figure 5 and Figure 10 The dewatering plate 2 includes two sets of dewatering sleeves 21. The ends of the two sets of dewatering sleeves 21 are rotatably connected to both sides of the inner wall of the dewatering tank 1 via hinge shafts 22. A dewatering telescopic plate 23 is slidably connected to the end of the dewatering sleeve 21 away from the inner wall of the dewatering tank 1. A lifting plate 24 is rotatably connected between the ends of the two sets of dewatering telescopic plates 23 away from the dewatering sleeves 21. A trapezoidal guide plate 5 is fixedly connected to the bottom of the dewatering tank 1. The lifting part includes a lifting screw 6, which is rotatably connected to the top of the trapezoidal guide plate 5. A threaded sleeve 61 is fixedly connected to the lifting plate 24. The top end of the lifting screw 6 passes through to the top of the inner cavity of the threaded sleeve 61 and is fixedly connected to a limit ring 62. The lifting screw 6 and the threaded sleeve 61 are threadedly connected. A drive motor is fixedly connected to the bottom of the trapezoidal guide plate 5. The output shaft of the drive motor 63 is fixedly connected to the bottom end of the lifting screw 6; two sets of lifting screw 6 and threaded sleeve 61 are symmetrically arranged along the center of the lifting plate 24, and a linkage gear 64 is fixedly connected to the bottom outer wall of both sets of lifting screw 6; transmission gears 65 are rotatably connected to both sides of the inner wall of the dehydration tank 1 through bearing seats, and the transmission gears 65 and the linkage gears 64 are connected by a ring rack 66; a feed hopper 101 is fixedly connected to the top of the dehydration tank 1, and the output end of the feed hopper 101 passes through the sealing plate 4 and communicates with the upper cavity of the dehydration tank 1; drain pipes 102 are fixedly connected to both sides of the bottom of the dehydration tank 1, and the drain pipes 102 communicate with the bottom of the inner cavity of the dehydration tank 1; and solenoid valves are installed in the conveying pipe of the feed hopper 101 and the drain pipe 102.

[0037] With the above-described structure, the quartz sand to be dewatered is fed from the feed hopper 101 into the dewatering tank 1. After loading, the solenoid valves in the feed hopper 101 and the drain pipe 102 are closed. At this time, the water in the quartz sand will pass through the drain sleeve 21, the drain telescopic plate 23, and the lifting plate 24 under the action of gravity, achieving initial dewatering of the quartz sand. Then, the drive motor 63 is turned on, and in conjunction with the transmission relationship of the linkage gear 64, the transmission gear 65, and the ring rack 66, the lifting screws 6 on both sides rotate simultaneously. At this time, the threaded sleeves 61 on both sides will slide upward along the lifting screws 6, thereby driving the lifting plate 24 to move vertically upward. At this time, in conjunction with the hinge shaft 22 and the rotation between the lifting plate 24 and the drain telescopic plate 23, the drain sleeve 21 will flip upward along the hinge shaft 22, thus causing... The drain extension plate 23 retracts into the drain sleeve plate 21. After the drain sleeve plate 21, the drain extension plate 23, and the lifting plate 24 are at the same level, the continued upward movement of the lifting plate 24 will pull the drain extension plate 23 out of the drain sleeve plate 21. When the threaded sleeve 61 moves to the top of the lifting screw 6, it will turn downward and repeat the above-mentioned pushing action on the drain sleeve plate 21 and the drain extension plate 23. This process is repeated to achieve the up-and-down flipping of the drain sleeve plate 21 and the drain extension plate 23, which makes the quartz sand accumulated on it turn over. This helps to ensure that the quartz sand is evenly distributed in the dehydration tank 1, avoiding excessive local accumulation of water or uneven drying, thereby improving the overall dehydration effect. It also changes the stacking gap of the quartz sand, making it easier for water to be discharged under gravity, further improving the dehydration effect.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The trapezoidal guide plate 5 has a sand discharge trough 51 in the middle, and a sand guide plate 52 is fixedly connected to the side wall of the trapezoidal guide plate 5. A sand discharge sleeve 53 is fixedly connected to the bottom of the lifting plate 24. The sand discharge sleeve 53 is inserted into the sand discharge trough 51. The top of the sand discharge sleeve 53 is connected to the cavity of the dehydration tank 1 above the lifting plate 24. Locking plates 531 and 532 are slidably inserted into both sides of the sand discharge sleeve 53. The locking plates 531 are inserted into the locking plates 532. Electric push rods 533 are fixedly connected to both sides of the sand discharge sleeve 53. The telescopic ends of the electric push rods 533 on both sides are fixedly connected to the side walls of the locking plates 531 and 532, respectively.

[0039] With the above structure, after the quartz sand is dewatered, the electric push rods 533 on both sides extend, thereby pushing the locking plate 531 and the locking sleeve 532 to move to both sides, thereby opening the sand discharge sleeve 53, so that the quartz sand falls along the sand discharge sleeve 53 and the sand discharge trough 51 onto the sand guide plate 52, and finally slides out of the dewatering tank 1 along the sand guide plate 52, thereby improving the convenience of material discharge.

[0040] Reference Figure 2 , Figure 4 and Figure 6 The air pressure section includes a first magnetic plate 7. The shaft of the transmission gear 65 extends into the bottom cavity of the air extraction box 3. The first magnetic plate 7 is sleeved and fixed on the shaft of the transmission gear 65 located in the bottom cavity of the air extraction box 3. Three sets of air pressure grooves 71 are respectively opened between the bottom and top cavities of the air extraction box 3. Air pressure plates 72 are slidably connected in the air pressure grooves 71. A first spring 721 is fixedly connected between the top of the air pressure plate 72 and the air pressure groove 71. The air pressure plate 72 and the first magnetic plate 7 are magnetically repelled. The side wall of the air pressure groove 71 is fixed and connected to an air extraction pipe 73. The other end of the air extraction pipe 73 is connected to the bottom cavity of the dehydration tank 1. The side wall of the top cavity of the air extraction box 3 is fixed and connected to an inflation pipe 74. The other end of the inflation pipe 74 is connected to the inner cavity of the pressure accumulator 41. A one-way valve is provided in both the air extraction pipe 73 and the inflation pipe 74.

[0041] It should be noted that the one-way valve in the suction pipe 73 can only allow the gas in the bottom cavity of the dehydration tank 1 to enter the pressure tank 71; the one-way valve in the inflation pipe 74 can only allow the gas in the pressure tank 71 to enter the accumulator chamber 41.

[0042] With the above structure, when the first magnetic plate 7 and the air pressure plate 72 are separated from the magnetic area, the air pressure plate 72 will be reset under the rebound action of the first spring 721 and generate a suction force in the air pressure groove 71, thereby opening the one-way valve in the suction pipe 73, so that the gas located in the bottom cavity of the dehydration tank 1 is sucked into the air pressure groove 71, thereby reducing the air pressure in the bottom cavity of the dehydration tank 1 and generating a suction force in the bottom cavity of the dehydration tank 1, so that the gas in the upper cavity of the dehydration tank 1 moves quickly to the bottom cavity of the dehydration tank 1. In this way, the moisture carried on the surface of the quartz sand is taken away by the gas flow. With the flipping action of the drain sleeve plate 21 and the drain telescopic plate 23, the dehydration efficiency of the quartz sand is effectively accelerated.

[0043] Reference Figures 7-9The hinge shaft 22 has vibration grooves 8 on both sides of its inner cavity. A guide slide rod 81 is fixedly connected between the middle of the two vibration grooves 8. A striking sleeve 82 is fixedly connected at equal intervals on the inner wall of the vibration groove 8. A striking block 83 is slidably connected inside the striking sleeve 82. A magnetic ring 84 is slidably connected on the guide slide rod 81. A second spring 841 is fixedly connected between the side wall of the magnetic ring 84 and the inner wall of the vibration groove 8. The magnetic ring 84 and the striking block 83 are magnetically connected. A first pull rope 842 is fixedly connected between the side walls of the two magnetic rings 84. A sealing tube 85 is fixedly connected to the top of the air pressure plate 72 located in the middle air pressure groove 71. The tube 85 extends upward through the vacuum box 3 and is slidably connected to it in a sealed manner. A second pull rope 851 is fixedly connected to the top of the air pressure plate 72. The second pull rope 851 passes through the sealed tube 85 and is fixedly connected to the bottom end of the first pull rope 842. The magnetic ring 84 includes a first magnetic ring 843 and a second magnetic ring 844. The first magnetic ring 843 is magnetically attracted to the striking block 83, while the second magnetic ring 844 is magnetically repelled by the striking block 83. The repulsive force of the second magnetic ring 844 is greater than the attractive force of the first magnetic ring 843. This ensures that the striking block 83 can move quickly when in a repulsive state, thereby obtaining a stronger striking effect and ensuring the shaking off of water.

[0044] With the above-described structure, during the upward movement of the pneumatic plate 72, the first pull rope 842 and the second pull rope 851 will be relaxed. At this time, the second spring 841 will pull the magnetic ring 84 to move, causing the magnetic ring 84 to move out of the area where the striking box 82 is located along the guide slide rod 81. When the pneumatic plate 72 returns to its original position under the rebound action of the first spring 721, it will pull the magnetic ring 84 to move along the guide slide rod 81 towards the striking box 82. First, the first magnetic ring 843 and the striking block 83 will... The attraction between the two magnetic rings causes the striking block 83 to move closer to the first magnetic ring 843. Then, the second magnetic ring 844 will move to the striking block 83. At this time, under the repulsive force between the striking block 83 and the second magnetic ring 844, the striking block 83 will move rapidly away from the second magnetic ring 844, thereby hitting the end of the striking sleeve 82. This will generate an impact vibration within the hinge shaft 22, causing the water adhering to the surface of the quartz sand to be shaken off quickly, effectively improving the dewatering efficiency of the quartz sand.

[0045] Reference Figure 5 , Figure 6The pressure relief section includes two sets of pressure relief seats 9, which are fixed on both sides of the sealing plate 4. Pressure relief grooves 91 and trigger grooves 92 are respectively opened on both sides of the inner cavity of the pressure relief seat 9. The bottom ends of the pressure relief grooves 91 and trigger grooves 92 are connected to the upper cavity of the dehydration tank 1. A limiting slide groove 93 is opened between the top of the pressure relief grooves 91 and trigger grooves 92. A pressure relief plate 94 is slidably connected in the limiting slide groove 93. A third spring 941 is fixedly connected between the two sides of the pressure relief plate 94 and the top of the limiting slide groove 93. A pressure relief hole 95 is opened on the side wall of the pressure relief groove 91. The pressure relief hole 95 is connected to the inner cavity of the pressure accumulator 41. The threaded sleeves 61 on both sides are aligned with the center of the inner cavity of the trigger grooves 92 on both sides, and the inner diameter of the trigger groove 92 is equal to the outer diameter of the threaded sleeve 61.

[0046] With the above-described structure, during the rotation of the transmission gear 65, the first magnetic plate 7 in the bottom cavity of the suction box 3 will be rotated synchronously. When the first magnetic plate 7 rotates to below the pressure groove 71, the repulsive force between the first magnetic plate 7 and the pressure plate 72 will cause the pressure plate 72 to retract upwards into the pressure groove 71, thereby squeezing the gas in the pressure groove 71 and opening the one-way valve in the inflation pipe 74, allowing the gas originally in the pressure groove 71 to enter the pressure accumulator 41 along the inflation pipe 74. As the gas continuously fills the accumulator chamber 41, the air pressure inside the accumulator chamber 41 will increase. When the threaded sleeve 61 climbs to the top of the lifting screw 6, it will simultaneously insert into the trigger groove 92 and push the pressure relief plate 94 to move upward, causing the pressure relief plate 94 to disengage from the pressure relief hole 95. At this time, the high-pressure gas accumulated in the accumulator chamber 41 will be quickly blown from top to bottom through the pressure relief groove 91 onto the quartz sand. In this way, the moisture on the surface of the quartz sand will be carried away by the rapidly flowing airflow, further accelerating the dehydration efficiency of the quartz sand.

[0047] Reference Figures 1-10In this invention, during use, the quartz sand to be dehydrated is fed from the feed hopper 101 into the dehydration tank 1. After loading, the solenoid valves in the feed hopper 101 and the drain pipe 102 are closed. At this time, the water in the quartz sand will pass through the drain sleeve 21, the drain telescopic plate 23, and the lifting plate 24 under the action of gravity, achieving preliminary dehydration of the quartz sand. Then, the drive motor 63 is turned on, and in conjunction with the transmission relationship of the linkage gear 64, the transmission gear 65, and the ring rack 66, the lifting screws 6 on both sides rotate simultaneously. At this time, the threaded sleeves 61 on both sides will slide upward along the lifting screws 6, thereby driving the lifting plate 24 to move vertically upward. At this time, in conjunction with the hinge shaft 22 and the rotation between the lifting plate 24 and the drain telescopic plate 23, the drain sleeve 21 will flip upward along the hinge shaft 22, and the drain telescopic plate 23 will move towards the drain. The drain sleeve 21 is retracted. After the drain sleeve 21, drain telescopic plate 23, and lifting plate 24 are in the same horizontal state, the continued upward movement of the lifting plate 24 will pull the drain telescopic plate 23 out of the drain sleeve 21. When the threaded sleeve 61 moves to the top of the lifting screw 6, it will turn downward and repeat the above-mentioned pushing action on the drain sleeve 21 and the drain telescopic plate 23. This process is repeated to achieve the up-and-down flipping of the drain sleeve 21 and the drain telescopic plate 23, which makes the quartz sand accumulated on it turn over. This helps to ensure that the quartz sand is evenly distributed in the dehydration tank 1, avoiding excessive local accumulation of water or uneven drying and wetting, thereby improving the overall dehydration effect. It also changes the stacking gap of the quartz sand, making it easier for water to be discharged under the action of gravity, further improving the dehydration effect. At the same time, it also facilitates air circulation and ensures the effect of subsequent air blowing dehydration.

[0048] During the rotation of the transmission gear 65, the first magnetic plate 7 in the bottom cavity of the suction box 3 will rotate synchronously. When the first magnetic plate 7 rotates to below the pressure groove 71, the repulsive force between the first magnetic plate 7 and the pressure plate 72 will cause the pressure plate 72 to retract upward into the pressure groove 71, thereby squeezing the gas in the pressure groove 71 and opening the one-way valve in the inflation pipe 74, allowing the gas originally in the pressure groove 71 to enter the pressure accumulator 41 along the inflation pipe 74. Subsequently, when the first magnetic plate 7 and the pressure plate 72 are separated from the magnetic area, the pressure plate 72... The first spring 721 will return to its original position under the rebound action and generate a suction effect in the air pressure groove 71, thereby opening the one-way valve in the air extraction pipe 73, so that the gas located in the bottom cavity of the dehydration tank 1 is drawn into the air pressure groove 71. This process repeats, which will reduce the air pressure in the bottom cavity of the dehydration tank 1 and generate a suction effect, causing the gas in the upper cavity of the dehydration tank 1 to move quickly to the bottom cavity of the dehydration tank 1. In this way, the moisture carried on the surface of the quartz sand is carried away by the gas flow. Combined with the above-mentioned tumbling effect, the dehydration efficiency of the quartz sand is effectively accelerated. As gas continuously fills the accumulator chamber 41, the gas pressure inside the accumulator chamber 41 will increase. When the threaded sleeve 61 climbs to the top of the lifting screw 6, it will simultaneously insert into the trigger groove 92 and push the pressure relief plate 94 to move upward, causing the pressure relief plate 94 to disengage from the pressure relief hole 95. At this time, the high-pressure gas accumulated in the accumulator chamber 41 will be quickly blown from top to bottom towards the quartz sand through the pressure relief groove 91. Subsequently, when the threaded sleeve 61 moves in the opposite direction, under the rebound action of the third spring 941, the pressure relief plate 94 will reset and re-seal the pressure relief hole 95. This process is repeated to achieve a combination of upward blowing and downward suction to accelerate gas flow and further speed up the dewatering efficiency of the quartz sand.

[0049] As the pneumatic plate 72 moves upward, the first pull rope 842 and the second pull rope 851 will be relaxed. At this time, the second spring 841 will pull the magnetic ring 84 to move, causing the magnetic ring 84 to move out of the area where the striking box 82 is located along the guide slide rod 81. When the pneumatic plate 72 returns to its original position under the rebound action of the first spring 721, it will pull the magnetic ring 84 to move along the guide slide rod 81 towards the striking box 82, firstly causing the first magnetic ring 843 to be attracted to the striking block 83. The action causes the striking block 83 to move closer to the first magnetic ring 843. Then, the second magnetic ring 844 will move to the striking block 83. At this time, under the repulsive action between the striking block 83 and the second magnetic ring 844, the striking block 83 will move rapidly away from the second magnetic ring 844, thereby hitting the end of the striking sleeve 82. This will generate an impact vibration effect within the hinge shaft 22, causing the water adhering to the surface of the quartz sand to be shaken off quickly, effectively improving the dewatering efficiency of the quartz sand.

[0050] The separated water will fall onto the trapezoidal guide plate 5 and slide down to the bottom of the dewatering tank 1. Finally, the water can be discharged by opening the solenoid valve in the drain pipe 102. After the quartz sand is dewatered, the electric push rods 533 on both sides extend to push the locking plate 531 and the locking sleeve 532 to move to both sides, thereby opening the sand discharge sleeve 53. The quartz sand falls down along the sand discharge sleeve 53 and the sand discharge trough 51 onto the sand guide plate 52 and finally slides out of the dewatering tank 1 along the sand guide plate 52, thus completing the entire dewatering process of the quartz sand.
