Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater reuse treatment device for quartz sand production. Background Technology

[0002] Wastewater generated during quartz sand production mainly originates from processes such as washing, scrubbing, flotation, classification and desliming, and acid washing. The main pollutants in the wastewater include: Suspended solids: primarily from silt and fine quartz particles; Dissolved solids: including various metal salts (such as sulfates and chlorides); Heavy metal ions: such as iron, manganese, copper, and lead, especially abundant in acid washing wastewater; Acidic substances: residual acids produced during the acid washing process (such as sulfuric acid, hydrochloric acid, and hydrofluoric acid) make the wastewater highly acidic; Residual flotation reagents: such as collectors and inhibitors; Organic pollutants: trace amounts of organic matter may be present in some processing stages; Silicic acid and sulfurous acid: generated during the acid washing process from the reaction of silica with acid.

[0003] Wastewater generated during quartz sand production generally requires multi-stage wastewater treatment equipment to meet reuse standards. Currently, the main multi-stage wastewater treatment methods include collection, flocculation, sedimentation, filtration, and pH adjustment. During flocculation, workers add flocculant powder to the equipment. After the flocculant powder mixes and dissolves with the wastewater, it forms a flocculant solution that adsorbs floating matter, causing it to form flocs and settle. Because the flocculant powder is usually added in large quantities, some inevitably floats on the surface of the wastewater and cannot dissolve quickly, resulting in localized areas with less flocculant and thus lower overall flocculation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater recycling and treatment device for quartz sand production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater reuse treatment device for quartz sand production, comprising a collection tank, a treatment chamber, and a pH adjustment tank connected sequentially by pipelines; the treatment chamber is vertically equipped with a first partition and a second partition, which sequentially divide the treatment chamber into a flocculation chamber, a sedimentation chamber, and a filtration chamber; the first partition has an overflow port on its upper side; and further comprising:

[0006] A sliding plate is horizontally slidably connected to the top of the processing chamber and located above the flocculation chamber;

[0007] At least one lifting cylinder is vertically mounted on the top of the sliding plate and is driven by a lifting frame;

[0008] Multiple tubular sections are vertically installed on the lifting frame, with their upper and lower ends open.

[0009] A sealing unit is provided on the tubular portion and is used to seal the lower opening of the tubular portion;

[0010] The extrusion unit is located on the lifting frame and is used to generate extrusion force on the liquid inside the tubular section.

[0011] Furthermore, each of the collection tank, pH adjustment tank, and sliding plate is equipped with a stirrer on top.

[0012] Furthermore, a filter plate is horizontally fixed inside the filtration chamber, and the filter plate divides the interior of the filtration chamber into a packing chamber and a clarification chamber from top to bottom, and the clarification chamber is connected to the pH adjustment tank.

[0013] Furthermore, the sealing unit includes:

[0014] A hollow frame is fixed to the inner wall of the lower side of the tubular part;

[0015] A floating rod is vertically and slidably inserted through the hollow frame, and a limit nut is sleeved on the upper end of the floating rod;

[0016] A baffle is fixedly connected to the lower end of the floating rod;

[0017] A return spring is sleeved around the periphery of the floating rod, and its two ends elastically abut against the limiting nut and the hollow frame respectively in the direction of elastic force. The return spring has the potential energy to drive the baffle to move upward and seal against the lower end face of the tubular part.

[0018] Furthermore, a cylinder bracket is provided on one side of the processing chamber, and a horizontal push cylinder is installed on the cylinder bracket. The cylinder rod of the horizontal push cylinder is connected to the sliding plate and is used to drive the sliding plate to move horizontally back and forth.

[0019] Furthermore, the extrusion unit includes at least one extrusion cylinder vertically mounted on the top of the sliding plate. The extrusion cylinder is driven and connected to a floating plate. The floating plate is vertically mounted with multiple push rods. A piston portion is fixedly mounted at the lower end of each push rod. The piston portion is configured to slide in cooperation with the inner cavity of the tubular portion.

[0020] Furthermore, the tubular portion is integrally formed with a receiving chamber around its periphery. The inner diameter of the receiving chamber is larger than the inner diameter of the tubular portion, and the inner cavity of the receiving chamber communicates with the inner cavity of the tubular portion. The receiving chamber is provided with a vortex unit, which includes:

[0021] The flange ring is fixedly connected to the top wall of the receiving chamber;

[0022] The expansion portion is fixed to the lower end of the flange ring portion, and multiple deformation joints are provided around its periphery. The outer diameter of the expansion portion decreases sequentially from top to bottom.

[0023] An elastic film is wrapped around the outside of the expanded portion and is used to seal the deformation joint;

[0024] When the piston enters the expansion section, the expansion section will overcome its own elasticity and produce elastic expansion deformation, while the elastic film will simultaneously produce extension deformation.

[0025] Furthermore, a turbulence section is integrally formed and fixed to the lower end of the expansion portion, and the lower end of the turbulence section curls and extends outward toward the tubular portion.

[0026] Furthermore, a mounting ring is fixedly sleeved on the push rod, and an arc-shaped expansion plate coaxial with the push rod is fixedly connected to the mounting ring. When the piston part enters the expansion part, the outer wall of the arc-shaped expansion plate contacts the inner wall of the expansion part to assist in expanding the expansion part.

[0027] Furthermore, the wall thickness of the expanded portion is no more than 2mm and it is made of spring steel.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. In this invention, by setting up a tubular section, a sealing unit, and a squeezing unit, when the tubular section moves downward, the flocculant powder and wastewater floating on the liquid surface in the flocculation chamber can be sucked into the inner cavity of the tubular section together, reducing the amount of flocculant powder floating on the liquid surface. Subsequently, the squeezing unit squeezes the wastewater in the inner cavity of the tubular section, so that the wastewater can carry the flocculant powder to be quickly squeezed into the wastewater in the flocculation chamber, so that the flocculant powder will not float on the liquid surface, but can be quickly dissolved in the wastewater. This greatly increases the contact area and mixing intensity between the flocculant and the wastewater, thereby significantly accelerating the dissolution of the flocculant and improving its reaction efficiency and utilization rate.

[0030] 2. In this invention, by setting an expansion section and an elastic film, the outer diameter of the expansion section increases sequentially from top to bottom in its natural state. This allows the wastewater to generate a vortex when it enters the inner cavity of the tubular section. Under the action of the vortex, the wastewater can agitate the flocculant powder that enters the inner cavity of the tubular section together, so that the flocculant powder can be dispersed. At the same time, it can also be effectively mixed with the wastewater that generates the vortex, thereby allowing at least a portion of the flocculant powder to dissolve in the tubular section, thus improving the dissolution efficiency of the flocculant powder.

[0031] 3. In this invention, by setting a horizontal thrust cylinder to drive the sliding plate to move horizontally back and forth, the sliding plate can drive the tubular part to move horizontally back and forth. This allows the flocculant powder floating on the liquid surface of the flocculation chamber to fully enter the inner cavity of the tubular part, thereby reducing the amount of flocculant powder floating on the liquid surface of the flocculation chamber.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-11This invention provides a technical solution: a wastewater reuse treatment device for quartz sand production, comprising a collection tank 17, a treatment chamber 6, and a pH adjustment tank 1. The collection tank 17 has a first inlet at its upper end and a first outlet at its bottom. The treatment chamber 6 is vertically fixedly connected with a first partition 10 and a second partition 5 in sequence. The first partition 10 and the second partition 5 divide the inner cavity of the treatment chamber 6 into a flocculation chamber 7, a sedimentation chamber 4, and a filtration chamber 2 along the length of the treatment chamber 6. A filter plate 3 is horizontally fixedly connected in the filtration chamber 2. The filter plate 3 divides the inner cavity of the filtration chamber 2 into a packing chamber and a clarification chamber in sequence. The packing chamber is filled with packing material for filtering wastewater, such as activated carbon granules. A fixed plate is horizontally and fixedly connected to the top of the treatment chamber 6, positioned above the filter chamber 2. A first water pump is mounted on the fixed plate. The inlet and outlet of the first water pump are connected to the sedimentation chamber 4 and the packing chamber respectively via water pipes. A second water inlet connected to the flocculation chamber 7 is provided on the wall of the treatment chamber 6. A second water pump is installed between the collection tank 17 and the treatment chamber 6. The inlet of the second water pump is connected to the first outlet via a pipe, and the outlet of the second water pump is connected to the second inlet via a pipe. This allows... When the second water pump starts, it can transport the wastewater in the collection tank 17 to the flocculation chamber 7. An overflow port 11 is provided on the upper side of the first partition 10. The overflow port 11 is higher than the second water inlet. A third water outlet is provided on the side wall of the treatment chamber 6 away from the second water inlet. The third water outlet is connected to the clarification chamber. A third water pump is installed between the treatment chamber 6 and the pH adjustment tank 1. The inlet of the third water pump is connected to the third water outlet through a pipeline. A third water inlet is provided on the upper side of the pH adjustment tank 1. The third water inlet is connected to the outlet of the third water pump through a pipeline. A fourth water outlet is provided at the bottom of the pH adjustment tank 1. A sliding plate 9 is installed on the top of the water inlet and the treatment chamber 6. A stirrer 15 is installed on the top of the collection tank 17, the pH adjustment tank 1, and the sliding plate 9. The three stirrers 15 are used to stir the liquid in the collection tank 17, the flocculation chamber 7, and the pH adjustment tank 1, respectively. In addition, a linear rail is horizontally installed on each side of the top of the treatment chamber 6. The length direction of the linear rail is parallel to the length direction of the treatment chamber 6. Two sliders are installed on each linear rail. The four sliders on the two linear rails are connected to the sliding plate 9, so that the sliding plate 9 is horizontally slidably connected to the top of the treatment chamber 6.

[0046] Combination Figures 3 to 6As shown, the surface of the sliding plate 9 is provided with a flocculant powder inlet 12, which corresponds to the flocculation chamber 7. A cylinder bracket is installed on one side of the treatment chamber 6, and a horizontally mounted push cylinder 16 is mounted on the cylinder bracket. A connecting block is installed on the top of the sliding plate 9, and the cylinder rod of the push cylinder 16 is connected to the connecting block. This allows the cylinder rod of the push cylinder 16 to move the connecting block horizontally when it extends or retracts, thereby synchronously moving the sliding plate 9 horizontally. Lifting cylinders 13 are vertically mounted on both sides of the top of the sliding plate 9. The cylinder rods of the two lifting cylinders 13 extend into the flocculation chamber 7, and the cylinder rods of the lifting cylinders 13 are fixedly connected to connecting rods 24. The lower ends of the two connecting rods 24 are connected to the connecting rods 24. A lifting frame 23 is horizontally fixed to the lifting frame 23. Multiple tubular sections 8 are installed sequentially along the length of the lifting frame 23. The upper and lower ends of the tubular sections 8 are open. In addition, the upper side of the tubular section 8 is provided with a threaded section. The lifting frame 23 has a through groove for the tubular sections 8 to pass through freely. The threaded section of the tubular section 8 is threadedly connected to two threaded stop rings from top to bottom. The opposing surfaces of the two threaded stop rings are respectively pressed against the upper and lower side walls of the lifting frame 23 to securely install the tubular section 8 on the lifting frame 23. The cylinder rod of the lifting cylinder 13 extends or shortens, thereby enabling the connecting rod 24 to move downward or upward, so that the lifting frame 23 can move vertically, thereby synchronously driving the tubular section 8 to move up and down.

[0047] Combination Figures 6 to 11As shown, multiple extrusion cylinders 14 are vertically mounted on the sliding plate 9. A floating plate 19 is horizontally fixed to the lower ends of the cylinder rods of the multiple extrusion cylinders 14. Multiple push rods 18 are vertically mounted on the floating plate 19. The number and position of the push rods 18 correspond to the number and position of the multiple tubular sections 8. A piston section 20 is fixedly sleeved at the lower end of each push rod 18. The piston section 20 can slide freely up and down within the inner cavity of the tubular section 8. A perforated frame 35 is fixedly connected to the lower side of the tubular section 8. A floating rod 34 is coaxially inserted through the perforated frame 35. The floating rod 34... 5. The floating rod 34 slides freely. A baffle 22 is slidably sleeved at the lower end of the floating rod 34. Two clamping nuts 36 are threadedly sleeved at the lower end of the floating rod 34, and the two clamping nuts 36 respectively clamp the two shaft end faces of the baffle 22. A limiting nut 32 is threadedly sleeved at the upper end of the floating rod 34. In addition, a return spring 33 is wrapped around the periphery of the floating rod 34. The two ends of the return spring 33 elastically abut against the limiting nut 32 and the hollow frame 35 respectively in the direction of the elastic force. The return spring 33 is in a pre-compressed state and has the potential energy to drive the baffle 22 to move upward, so that the baffle 22... The upper surface of the piston 20 abuts against the lower end face of the tubular portion 8, and the abutting surface is sealed. When the tubular portion 8 is filled with liquid, the piston 20 slides downward in the inner cavity of the tubular portion 8. During the sliding process, the piston 20 will exert a squeezing force on the liquid in the inner cavity of the tubular portion 8, thereby causing the liquid hydraulic pressure to act on the surface of the baffle 22. This allows the baffle 22 to overcome the elastic resisting force of the return spring 33 on the limiting nut 32, thereby causing the baffle 22 to move downward and away from the tubular portion 8. At the same time, the limiting nut 32 will exert a resisting force on the return spring 33. 3. Compression is generated, causing the return spring 33 to accumulate elastic potential energy. As a result, there is a large gap between the upper surface of the baffle 22 and the lower end face of the tubular part 8, allowing the liquid in the inner cavity of the tubular part 8 to flow out through the gap. When the squeezing force on the liquid in the tubular part 8 disappears or weakens to a certain extent, the elastic potential energy accumulated by the return spring 33 is released, driving the limit nut 32 to move upward and causing the baffle 22 to move upward synchronously. This causes the upper surface of the baffle 22 to abut against the lower end face of the tubular part 8, and the abutting surface is sealed.

[0048] Please refer to this carefully. Figure 7 A receiving chamber 21 is integrally formed and fixed to the upper side of the tubular portion 8. The inner diameter of the receiving chamber 21 is larger than the inner cavity size of the tubular portion 8, and the inner cavity of the receiving chamber 21 communicates with the inner cavity of the tubular portion 8. Please refer to... Figures 7 to 9As shown, a flange ring 28 is fixedly connected to the top wall of the inner cavity of the receiving chamber 21. The flange ring 28 includes, from top to bottom, an annular portion and a cylindrical portion connected end to end. The annular portion of the flange ring 28 is fixed to the top wall of the inner cavity of the receiving chamber 21, and the outer diameter of the annular portion is the same as the inner diameter of the inner cavity of the receiving chamber 21. The diameter of the annular hole of the flange ring 28 is the same as the inner diameter of the tubular portion 8. An expanding portion 29 extending downward is integrally formed and fixed to the lower end face of the cylindrical portion of the flange ring 28. The outer diameter of the expanding portion 29 decreases from top to bottom, and the maximum outer diameter of the expanding portion 29 is the same as the outer diameter of the cylindrical portion of the flange ring 28. Please refer to the following for details. Figure 7 Furthermore, a turbulent flow section 31 is integrally fixed to the lower end of the expansion portion 29. The lower end of the turbulent flow section 31 curls and extends outward toward the outside of the tubular portion 8, and a turbulent flow cavity is formed between the turbulent flow section 31 and the inner wall of the receiving chamber 21. The turbulent flow cavity is roughly annular in shape. Multiple deformation slots 30 extending to the cylindrical surface of the turbulent flow section 31 and the flange ring portion 28 are provided around the periphery of the expansion portion 29. By providing these deformation slots 30, the inner wall of the expansion portion 29 expands when subjected to compressive force in the direction toward the outside of the tubular portion 8. The opening 29 is capable of elastic expansion deformation. An elastic membrane 27 is fitted onto the outer surfaces of the opening 29, the cylindrical portion of the flange ring 28, and the turbulent flow portion 31. The outline dimensions of the elastic membrane 27 match the outlines of the opening 29, the cylindrical portion of the flange ring 28, and the turbulent flow portion 31. The elastic membrane 27 can seal the deformation joint 30, and when the opening 29 elastically expands or contracts, the elastic membrane 27 can correspondingly extend and deform. Please refer to... Figures 4 to 10 As shown, a mounting ring 25 is fixedly sleeved on the periphery of the push rod 18. Multiple arc-shaped expansion plates 26 are fixedly connected to the periphery of the mounting ring 25 through a connecting plate. The arc-shaped expansion plates 26 are vertical, and the arc of the arc-shaped expansion plates 26 is coaxial with the axis of the push rod 18. In addition, the outer diameter of the arc-shaped expansion plates 26 is the same as the outer diameter of the piston part 20. Furthermore, the wall thickness of the expansion part 29 is no more than 2mm and is made of spring steel. This allows the expansion part 29 to have a large elastic expansion deformation range and reduces the plastic deformation of the expansion part 29.

[0049] Working principle of the invention:

[0050] The external wastewater conveying system draws wastewater generated during the quartz sand production process into the collection tank 17 through the first inlet. The agitator 15 installed on the top of the collection tank 17 agitates the wastewater. The second water pump starts and transports the wastewater in the collection tank 17 to the second inlet of the treatment chamber 6. The wastewater then enters the flocculation chamber 7 through the second inlet. When a certain liquid level is reached (a liquid level sensor can be installed on the sliding plate 9 or the surface of the treatment chamber 6 to monitor the liquid level of the flocculation chamber 7, and the liquid level sensor is used in conjunction with the external control cabinet to detect the liquid level of the flocculation chamber 7), the second water pump stops. The operator cuts open the packaging bag containing flocculant powder and pours the flocculant powder from the packaging bag into the flocculation chamber 7 through the flocculant powder inlet 12. The agitator 15 installed on the sliding plate 9 is started. The agitator 15 is set to a low speed (the speed of the agitator 15 is set by those skilled in the art according to the actual situation) to agitate the flocculant powder and accelerate its dissolution.

[0051] Since the flocculant powder is directly and in large quantities added into the flocculation chamber 7, some undissolved flocculant powder will float in the wastewater, resulting in a low dissolution efficiency of the flocculant powder. At this time, the lifting cylinder 13 is activated, and the cylinder rod of the lifting cylinder 13 extends to a fixed stroke so that the piston part 20 moves away from the tubular part 8, thereby opening the upper end of the tubular part 8. When the cylinder rod of the lifting cylinder 13 extends, it will drive the lifting frame 23 to move downward. When it moves downward, multiple tubular parts 8 will also move downward synchronously, and the upper side of the opening of the tubular part 8 will be slightly lower than the wastewater surface. As the tubular part 8 moves downward, when the lower end of the tubular part 8 is immersed in the wastewater, the wastewater surface will also rise to a certain extent, thereby allowing the wastewater and the flocculant powder floating on the surface to enter the inner cavity of the tubular part 8. After the flocculant powder and wastewater flow into the inner cavity of the tubular part 8, the inner cavity of the tubular part 8 will be filled with wastewater and flocculant powder.

[0052] As the flocculant powder floating on the liquid surface and wastewater flow into the inner cavity of the tubular section 8, the horizontal thrust cylinder 16 is activated. The cylinder rod of the horizontal thrust cylinder 16 extends and retracts at a set rate, thereby driving the sliding plate 9 to move horizontally and linearly back and forth at the top of the treatment chamber 6. This allows the flocculant powder floating on the liquid surface in the flocculation chamber 7 to fully enter the inner cavities of the multiple tubular sections 8. The flocculant powder and wastewater enter the inner cavity of the tubular section 8 together. Since the expansion section 29 is not subjected to extrusion force at this time, therefore... The outer diameter of the expansion section 29 decreases from top to bottom, and the inner diameter of the lower opening of the expansion section 29 is smaller than the inner diameter of the tubular section 8. Therefore, when the wastewater flows through the lower opening of the expansion section 29, it will be unable to overflow from the deformation joint 30 due to the sealing effect of the elastic membrane 27. At the same time, the wastewater will generate a vortex in the expansion section 29. Under the action of the vortex, the flocculant powder will be fully mixed with the wastewater, so that the flocculant powder can dissolve at least a certain extent.

[0053] After the inner cavity of the tubular section 8 is filled with wastewater and flocculant powder, the extrusion cylinder 14 is activated. The cylinder rod of the extrusion cylinder 14 extends, thereby driving the lifting frame 23 to move downward. When the lifting frame 23 moves downward, it causes multiple push rods 18 to drive the piston section 20 to move downward, thereby causing the piston section 20 to engage in the inner cavity of the tubular section 8. The cylinder rod of the extrusion cylinder 14 continues to extend, causing the piston section 20 to move downward in the inner cavity of the tubular section 8, and generating extrusion force on the wastewater in the tubular section 8, causing the wastewater to be squeezed by the piston. The compression of section 20 increases the squeezing force of the wastewater on baffle 22 until the squeezing force is greater than the elastic resisting force of the return spring 33 on the limit nut 32, causing baffle 22 to move downward and creating a gap between the upper surface of baffle 22 and the lower end face of tubular section 8. At this time, the wastewater and flocculant powder in tubular section 8 will quickly enter the wastewater in flocculation chamber 7 through the gap, thereby directly adding the flocculant powder into the wastewater. This allows the flocculant powder to dissolve quickly when it enters the wastewater.

[0054] As the piston 20 continues to move downwards, it enters the inner cavity of the expansion section 29, causing the periphery of the piston 20 to exert a compressive force on the inner wall of the expansion section 29. This causes the expansion section 29 to elastically expand and deform, resulting in the turbulence section 31 and the expansion section 29 bending and deforming towards the inner wall of the receiving chamber 21. When the expansion section 29 elastically expands, the piston 20 can pass through the inner cavity of the expansion section 29 and continue to slide to the lower side of the inner cavity of the tubular section 8, continuing to compress the wastewater. At the same time, the arc-shaped expansion plate 26 slides along with the piston 20 in the inner cavity of the expansion section 29, causing the arc-shaped expansion plate 26 and the expansion section 29 to... The inner wall slides into contact, and the expansion part 29 continues to expand. This allows the expansion part 29 to maintain elastic expansion deformation during the process of the piston part 20 squeezing the wastewater in the inner cavity of the tubular part 8. When the expansion part 29 expands elastically, the turbulent part 31 and the expansion part 29 will squeeze the wastewater remaining in the inner cavity of the receiving chamber 21, causing the wastewater to generate turbulence on the curved surface of the turbulent part 31. This allows the wastewater to cause the flocculant powder remaining in the inner cavity of the receiving chamber 21 to flow out of the inner cavity of the receiving chamber 21 quickly with the wastewater and enter the inner cavity of the tubular part 8, reducing the amount of flocculant powder remaining in the inner cavity of the tubular part 8.

[0055] After the piston 20 moves downwards into position, the elastic potential energy stored in the return spring 33 is released, causing the return spring 33 to drive the limit nut 32 to move upwards, causing the baffle 22 to move upwards and close the lower end face of the tubular part 8. Then, the lifting cylinder 13 drives the lifting frame 23 to move upwards, causing the tubular part 8 to move upwards until most of the upper end of the tubular part 8 is exposed above the wastewater surface in the flocculation chamber 7. At the same time, the squeezing cylinder 14 also contracts synchronously, driving the piston 20 to move upwards and reset. Under the action of the flocculant, the floating matter and particulate matter in the wastewater in the flocculation chamber 7 will form flocs and settle down. The second water pump starts and continues to transport the wastewater in the collection tank 17 to the flocculation chamber 7. As the liquid level rises, the clear water on the upper layer of the flocculation chamber 7 flows into the sedimentation chamber 4 through the overflow port 11 for sedimentation treatment. After sedimentation treatment to a certain extent, the first water pump starts and transports the sedimented upper layer of clear water to the packing chamber. The packing chamber filters the clear water, and the filtered clear water flows into the clarification chamber through the filter plate 3. The third water pump starts and transports the clarified clear water to the pH adjustment tank 1 for pH adjustment treatment. The treated clear water flows into the external treatment system or reuse system through the fourth outlet of the pH adjustment tank 1.
