Description

Technical Field

[0001] The present invention relates to the technical field of wastewater recycling and treatment, in particular to a wastewater recycling and treatment device for quartz sand production. Background Art

[0002] Quartz sand wastewater typically contains large amounts of solid impurities such as quartz sand particles and suspended matter. It may also carry certain acidity, alkalinity, or other pollutants due to the production process. Sedimentation treatment uses gravity to naturally settle larger suspended matter in the wastewater, removing some solid impurities and reducing the turbidity of the wastewater. Flocculation, by adding flocculants, aggregates tiny colloidal particles and suspended matter in the wastewater to form larger flocs, further enhancing solid-liquid separation and removing more fine particles and some organic pollutants that are difficult to naturally settle. The synergistic effects of sedimentation, flocculation, and neutralization can effectively remove suspended matter and adjust the pH value in quartz sand wastewater, laying the foundation for subsequent advanced treatment and reuse, ensuring that the quality of the reused water meets relevant standards and usage requirements.

[0003] In Chinese Patent No. 201820773113.9, the utility model discloses an acid-base wastewater treatment device, comprising a support frame and an intermediate water tank, wherein a water inlet pipe of the auxiliary pipe zone is installed on one side of the bottom end of the outer wall of the support frame, a condensation zone vent pipe is installed on the outer wall of the support frame and the upper end of the water inlet pipe is installed, and the top of the support frame is fixedly connected to the auxiliary pipe condensation zone. In this acid-base wastewater treatment device, after sufficient mixing and reaction, the wastewater enters the inclined tube sedimentation zone, where suspended matter in the wastewater is settled and removed, and the settled sludge is conveniently discharged outward through the sludge discharge pipe. Since the suspended particles in the wastewater are relatively light and difficult to settle, the inclined tube sedimentation zone is designed to have a longer residence time. The effluent from the inclined tube sedimentation zone enters the intermediate water tank, and the effluent from the inclined tube sedimentation tank enters the intermediate water tank. The water in the intermediate water tank is lifted by the intermediate lifting pump to the sand filter and activated carbon filter to further remove the residual suspended matter in the wastewater, thereby achieving the effect of treating the acid-base wastewater.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the flocculants themselves have a certain viscosity. When the water flow carries the flocculants through the inclined tube and the water flow rate is slow during the sedimentation process, these floccules are easy to adhere to the inner wall of the inclined tube. The long-term adhesion accumulation will gradually affect the water flow capacity of the inclined tube and its sedimentation effect. In addition, when mixing the flocculant and the water body, the existing wastewater treatment device usually uses the rotation of the stirring blade to achieve mixing. The shear force brought by the stirring blade can easily damage the formed flocculants. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that in the prior art, flocs adhere to the inner wall of the inclined tube, and long-term accumulation will affect its performance.

DETAILED DESCRIPTION

[0031] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0032] Reference Figure 1 and Figure 8 As shown, the present invention provides a technical solution: a wastewater reuse treatment device for quartz sand production, including a primary sedimentation component 7, the primary sedimentation component 7 includes a sedimentation tank 701, a buffer pipe 702 is coaxially arranged inside the sedimentation tank 701, the side of the buffer pipe 702 is connected to a water inlet pipe 703, a mud discharge pipe 704 is fixedly connected to the side of the inside of the sedimentation tank 701, and an overflow trough 705 is fixedly connected to the top of the sedimentation tank 701, and the overflow trough 705 is connected to the first water supply pipe 9.

[0033] The wastewater generated during the production of quartz sand enters the interior of the buffer pipe 702 through the water inlet pipe 703 and flows downward along the buffer pipe 702 into the interior of the sedimentation tank 701. The buffer pipe 702 is used to weaken the impact of the incoming water flow on the sediment settled at the bottom. Under the action of gravity, some large particles of sediment and other impurities in the wastewater settle at the bottom of the sedimentation tank 701 and are discharged to the outside through the mud discharge pipe 704. The water after the preliminary sedimentation treatment enters the interior of the overflow trough 705 and is transported to the interior of the flocculation tank body 1 through the first water supply pipe 9 for subsequent flocculation treatment.

[0034] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 9 As shown, a partition component 5 is provided in the middle position of the flocculation tank body 1, and the partition component 5 divides the interior of the flocculation tank body 1 into two parts, a first tank body and a second tank body, of equal volume. A primary sedimentation component 7 is provided on one side of the flocculation tank body 1, and an acid-base regulating tank 12 is provided on the other side of the flocculation tank body 1. A first water pipe 9 is fixedly connected to the top of the primary sedimentation component 7, and two groups of second water pipes 11 are fixedly connected to the output end of the first water pipe 9, and a valve 10 is installed at the connection between the two groups of second water pipes 11, and one group of the second water pipes 11 is connected to the first tank body, and the other group of the second water pipes 11 is connected to the second tank body. A flocculant dispenser 8 is installed on the top of the flocculation tank body 1, and two groups of drug injection ports are installed at the bottom end of the flocculant dispenser 8, one group of drug injection ports is connected to the first tank body, and the other group of drug injection ports is connected to the second tank body.

[0035] Under the control of the valve 10, the first water pipe 9 can only discharge the water that has undergone preliminary sedimentation treatment into the interior of the flocculation tank body 1 through one group of the second water pipes 11. When discharged into the first tank body inside the flocculation tank body 1, the group of dosing ports corresponding to the lower end of the flocculant dosing machine 8 also dosing flocculant into the interior of the first tank body. At this time, the first tank body plays a role in mixing and stirring the flocculant and the water body. After the flocculant and the water body are mixed, they are passed into the interior of the second tank body together. At this time, the second tank body plays a role in settling the flocs.

[0036] A support frame 6 is installed inside the flocculation tank body 1, a first elevator 3 is installed at the bottom of the support frame 6, an inclined tube assembly 4 is installed at the output end of the first elevator 3, the inclined tube assembly 4 includes an upper fixed layer 401, and the upper fixed layer 401 is fixedly connected to the output end of the first elevator 3, and the upper fixed layer 401 is slidably connected to the inside of the flocculation tank body 1, a plurality of upper inclined tubes 402 are evenly arranged inside the upper fixed layer 401, a lower fixed layer 404 is provided at the bottom of the upper fixed layer 401, and a space is formed between the lower fixed layer 404 and the upper fixed layer 401. The baffle comprises a buffer layer cavity 406, and two groups of connecting blocks 403 are symmetrically arranged on the sides of the buffer layer cavity 406. The top ends of the connecting blocks 403 are fixedly connected to the upper fixed layer 401, and the bottom ends of the connecting blocks 403 are fixedly connected to the lower fixed layer 404. A number of lower inclined tubes 405 are evenly arranged inside the lower fixed layer 404. The lower inclined tubes 405 are staggered with the upper inclined tubes 402. The end of the upper inclined tube 402 close to the buffer layer cavity 406 is set to a gradually expanding shape, and the end of the lower inclined tube 405 close to the buffer layer cavity 406 is also set to a gradually expanding shape.

[0037] Inside the first tank body that plays a mixing role, after the water and flocculant are added, the first elevator 3 is started, and the output end of the first elevator 3 carries the inclined tube assembly 4 as a whole to move up and down inside the flocculation tank body 1. When the inclined tube assembly 4 rises, the water flows in from the upper inclined tube 402 and is finally discharged from the lower inclined tube 405. When the overall water flow layer is divided into multiple tributaries and enters the interior of each upper inclined tube 402, a number of vortices will be formed at the inlet of each upper inclined tube 402. When it flows from the bottom end of the upper inclined tube 402 into the interior of the buffer layer cavity 406, a number of vortices will be formed at the outlet of each upper inclined tube 402, and the aggregation will be completed inside the buffer layer cavity 406, and it will be divided into several tributaries again through the top of the lower inclined tube 405. At the same time, it will have a disturbing effect on the water flow, and the outlet end of the upper inclined tube 402 and the inlet end of the lower inclined tube 405 are staggered to facilitate mixing of water at each branch, and finally discharged outward from the bottom end of the lower inclined tube 405, and forming a number of vortices at the end of the lower inclined tube 405. When the inclined tube assembly 4 descends, the process is the opposite. During the back and forth lifting and lowering process of the inclined tube assembly 4, multiple vortices can be formed repeatedly on the water body inside the first tank body. In this process, after the flocculant is added, it will be continuously dispersed and diffused to the entire water body under the action of the vortex and turbulence caused by the movement of the inclined tube assembly 4, breaking the concentration gradient and achieving uniform mixing with the wastewater; at the same time, the up and down movement of the inclined tube layer can also continuously update the contact interface between the water and the inclined tube surface, thereby enhancing the mass transfer process.

[0038] Traditional blade stirring relies on mechanical rotation to generate unidirectional shear force. When rotating at high speed, it is easy to apply concentrated external force to the formed flocs, causing the flocs to break. The vortex and turbulence caused by the lifting and lowering of the inclined tube assembly 4 in this application belong to the three-dimensional flow field effect. The direction of the water flow is constantly changing and the shear force distribution is more uniform. The shear force in a single vortex is smaller, and the impact on the flocs is softer, which can reduce the breakage of the flocs and better maintain the integrity of the flocculent material, which is conducive to subsequent sedimentation. On the other hand, when the inclined tube assembly 4 moves, the water flows through the gradually expanding pipe mouth, the staggered pipe mouth and the buffer layer cavity 406 and other structures, forming multi-region and multi-directional vortices at different positions. Compared with traditional blade stirring, this mixing method has more comprehensive coverage. At the same time, the up and down reciprocating motion of the inclined tube layer continuously updates the contact interface between the water and the inclined tube surface, strengthens the mass transfer process, and makes the flocculant and water body more efficiently and evenly mixed in the three-dimensional flow field. The mixing efficiency is significantly improved, and the problem of floc destruction caused by local high shear force in traditional stirring is avoided.

[0039] During the lifting and lowering process of the inclined tube assembly 4, the water flow will pass back and forth repeatedly from the upper inclined tube 402 and the lower inclined tube 405 inside it, and under the contraction effect of its gradually expanding port, it can generate a certain scouring force on the inner walls of the upper inclined tube 402 and the lower inclined tube 405, and the flocs have the characteristics of loose structure and weak adhesion. The scouring force generated by the water flow passing through the upper inclined tube 402 and the lower inclined tube 405 is sufficient to separate the flocs and impurities attached to their inner walls, effectively preventing their accumulation and ensuring the smooth passage. At the same time, it reduces the problems of reduced treatment efficiency and water quality deterioration caused by blockage, reduces the frequency of equipment maintenance, ensures the stable and efficient operation of the mixing and subsequent sedimentation treatment processes, completes scouring and cleaning while mixing, and regularly exchanges the functions of the first and second tank bodies so that both tank bodies have the opportunity to play the mixing function within a certain period of time and scour the inner walls of their inclined tubes at the same time. There is no need to drain all the water inside the entire tank body and then clean it specifically, which is convenient for saving manpower and material resources.

[0040] See also Figure 6 and Figure 7 The partition assembly 5 includes a partition plate 501, which is fixedly connected to the middle position inside the flocculation tank body 1. A water outlet 504 is provided at the bottom of the partition plate 501. The first tank body is connected to the second tank body through the water outlet 504. A servo motor 502 is installed inside the partition plate 501. The output end of the servo motor 502 is fixedly connected to a transmission connecting rod 503. The transmission connecting rod 503 is rotatably connected to the inside of the partition plate 501. The bottom end of the transmission connecting rod 503 is fixedly connected to a screw 506. The inside of the water outlet 504 is slidably connected to a sealing plate 505. The screw 506 is inserted into the inside of the sealing plate 505, and the screw 506 and the sealing plate 505 are threadedly connected.

[0041] The output end of the servo motor 502 rotates forward or reverse through the transmission connecting rod 503 with the screw 506, and then can drive the sealing plate 505 to rise or fall, so that the sealing plate 505 can be used to complete the opening or blocking of the water outlet 504. When one of the pools is raised and lowered with the inclined tube assembly 4 to mix the flocculant and wastewater, the sealing plate 505 closes the water outlet 504 to prevent the wastewater from invading another pool body. When the flocculant mixing is completed and the flocs are generated, the wastewater needs to be transferred to complete the sedimentation of the flocs. The sealing plate 505 moves upward to open the water outlet 504, and the wastewater can be transferred to another pool body through the water outlet 504.

[0042] See also Figure 3 and Figure 5 As shown, an overflow assembly 2 is also provided inside the flocculation tank body 1, and the overflow assembly 2 includes a second elevator 201, and the second elevator 201 is fixedly connected to the bottom of the support frame 6. The output end of the second elevator 201 is fixedly connected to the overflow pipe 202, and a number of overflow holes 203 are evenly opened on the side of the overflow pipe 202. The end of the overflow pipe 202 is fixedly connected to a water suction hose 204, and the water suction hose 204 is connected to the overflow pipe 202. The top of the water suction hose 204 is fixedly connected to a third water supply pipe 205, and the output end of the third water supply pipe 205 is connected to the acid-base adjustment tank 12.

[0043] In the pool body that plays a sedimentation role, the flocs settle below the inclined tube assembly 4, and the wastewater after flocculation treatment enters the overflow pipe 202 through the overflow hole 203, and is transported into the interior of the acid-base adjustment tank 12 through the water suction hose 204 and the third water supply pipe 205, and is mixed with the reagents put into the acid-base adjustment tank 12 to adjust its pH. After the adjustment is completed, it can be transferred to the quartz sand production line for reuse. The output end of the second elevator 201 can be adjusted in height with the overflow pipe 202, so that the liquid level inside the pool body that plays a sedimentation role is lower than the liquid level inside the pool body that plays a stirring role, so that the waste liquid containing flocs after being mixed with the flocculant can enter the interior of the pool body that plays a sedimentation role through the sealing plate 505 below the partition assembly 5.

[0044] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
