Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, specifically a sludge and wastewater separation and treatment device. Background Technology

[0002] Due to the complexity of urban pipe network construction, combined sewer systems (combined stormwater and sewage) still exist in many towns and cities. Therefore, wastewater treatment plants must not only treat domestic sewage from urban residents but also handle large amounts of rainwater. As rainwater washes over streets, it carries fine inorganic particles such as sand, which enter the urban sewage network through open collection systems along the roads, such as storm drains, and eventually reach the wastewater treatment plant. Especially in northern regions with severe wind and dust storms, wastewater treatment plants may collect large amounts of inorganic particles. These particles are difficult to degrade in processes primarily using activated sludge microbial treatment and accumulate within the treatment structures, severely impacting wastewater treatment efficiency. Therefore, effective removal of these inorganic particles is essential during the pretreatment stage.

[0003] Currently, in the pretreatment stage, facilities such as grit chambers are typically used, along with sand-water separators, to remove inorganic particles such as sand and gravel. Regardless of whether a cyclone grit chamber, aerated grit chamber, or other types of grit chamber are used, further separation of sand and water is required. Only when used in conjunction with a sand-water separator can a complete sand-water separation system be formed.

[0004] Existing sand-water separators typically consist of a shaftless screw conveyor, a conical tank, an outlet weir, and a drive unit. Separation primarily relies on the shaftless screw conveyor lifting the sand and gravel. However, in existing equipment, the inlet pipe is often suspended in the middle of the tank, and the falling water creates a certain velocity and impact force. This impact force may disperse the rising sand and gravel, causing it to resuspend in the water and reducing separation efficiency. Simultaneously, the incoming water disturbs the water in the U-shaped channel, making the sand and gravel's ascent unstable. This disturbance may impede the sand and gravel's ascent or even carry it back to the bottom of the channel. Furthermore, the impacting water flow causes the disturbed portion containing smaller sand and gravel to rise and suspend even higher, affecting the sand removal effect of the overflow water. Utility Model Content

[0005] The purpose of this invention is to provide a sludge and wastewater separation and treatment device that buffers the flushing water flow, reduces the scouring effect of the water flow on the rising sludge and sand, prevents the sludge and sand from resuspending in the water, and improves the efficiency of sand-water separation.

[0006] To achieve the above objectives, this utility model employs the following technical solution: A sludge and wastewater separation and treatment device includes a tank body with an opening at the top and a U-shaped trough integrally connected to the bottom of the tank body. The U-shaped trough is inclined and has shaftless spiral blades installed inside. The top of the U-shaped trough has a downward-facing sand discharge port. An overflow trough parallel to the side of the tank opening away from the sand discharge port is provided. One end of the overflow trough has a water outlet. An upright water inlet pipe is fixed to the side of the overflow trough near the sand discharge port. An installation plate is fixed to the side of the overflow trough away from the water inlet pipe. The installation plate is upright and has a guide plate at an angle of 100° to 120° on its bottom side. The vertical range of the guide plate covers the area below the water inlet pipe, and the side of the guide plate near the sand discharge port is the lower side.

[0007] The top sides of the overflow trough walls on both sides are provided with triangular toothed grooves, and the overflow trough is 10-30cm away from the side of the box opening.

[0008] The inlet pipe is externally provided with a secondary hoop plate and a tertiary hoop plate that enclose it. The secondary hoop plate and the tertiary hoop plate are semi-circular and oppositely arranged arc-shaped plate structures. The secondary hoop plate has secondary ear plates on both sides, and the tertiary hoop plate has tertiary ear plates on both sides. The secondary ear plates and the tertiary ear plates are fastened together with bolts. The outer side of the tertiary ear plate is provided with an L-shaped folding plate integrally formed therewith. The folding plate is fixed to the side wall of the overflow trough with bolts. There is a distance of not less than 15cm between the inlet pipe and the side wall of the overflow trough.

[0009] The guide plate has through holes near its two side edges. A vertically installed pull rod runs through the through hole. A stop block is fixed at the bottom of the pull rod. An angle plate is provided on the upper part of the pull rod. The angle plate is fixed to the side of the overflow tank near the water inlet pipe. A large nut is fixed on the angle plate and runs through it. The large nut is passed through by the pull rod and the two are threaded together.

[0010] A guide tube is provided on the lower side of the guide plate. The guide tube is a cylindrical straight tube with its axis parallel to the overflow channel. The bottom side of the guide plate is set lower than the top side of the guide tube.

[0011] The guide tube has vertical plates on both sides, and a cylinder shaft connected to the vertical plates is coaxially arranged on both sides of the guide tube. A horizontal plate perpendicular to the top of the vertical plate is fixed, and a beam frame fixedly connected to the horizontal plates on both sides is arranged between the horizontal plates. A downwardly extending portal groove is fixed on the outer side of the horizontal plate away from the guide tube, and the portal groove is movably inserted into the edge of the box opening.

[0012] Strip-shaped components are fixed on both sides of the box opening, and upright plates are provided on both sides of the flow guide tube. A cylindrical shaft connected to the upright plates is coaxially provided on both sides of the flow guide tube. A horizontal plate perpendicular to the top of the upright plate is fixed, and a beam frame fixedly connected to it is provided between the two horizontal plates. A downwardly extending portal groove is fixed on the outer side of the horizontal plate away from the flow guide tube. The portal groove is movably inserted into the strip-shaped components and the edge of the box opening. An upper threaded sleeve is fixed on the horizontal plate and passes through it. An upright support screw is threaded into the upper threaded sleeve. The bottom end of the support screw rests on the top side end face of the strip-shaped component.

[0013] A side threaded sleeve extends through the outer side of the gate-shaped groove near the bottom, and a fastening screw is fitted into the internal thread of the side threaded sleeve.

[0014] The cylindrical shaft is rotatably connected to the bottom side of the vertical plate. An upper sprocket driven by a stepper motor is provided on one side of the horizontal plate, and a lower sprocket is fixed on the cylindrical shaft on the same side. The upper sprocket and the lower sprocket are driven by a chain.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) By setting an inclined guide plate below the inlet, the water flow can be buffered and blocked, reducing the scouring effect of the water flow on the rising mud and sand, and preventing the mud and sand from being resuspended in the water, thereby improving the efficiency of sand-water separation.

[0016] (2) The inclined design of the guide plate helps to guide the water flow along the designed path, so that the water flow forms a relatively stable flow state in the separator, reducing the interference of the water flow on the sediment separation process and further improving the separation effect.

[0017] (3) The inclined guide plate, combined with the continuous flow of water, can continuously flush the guide plate, effectively preventing the accumulation of sand and gravel on the guide plate, reducing the burden of maintenance and cleaning, lowering the maintenance cost of the equipment, and improving the operating efficiency of the equipment.

[0018] (4) The baffle plate can prevent the water containing small-sized sand and gravel from rising and suspending too high, thereby reducing the sand and gravel content in the overflow water, improving the sand removal effect of the overflow water, and reducing the burden of subsequent treatment.

[0025] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0026] Example 1:

[0027] This example has a similar overall structure to the existing technology, including: a box 1 with a conical bottom; a U-shaped trough 2 integrally formed and inclined with the bottom of the box 1; a frame at the top of the U-shaped trough 2; a lifting motor installed inside the frame; and shaftless spiral blades 3 arranged in the same direction within the U-shaped trough 2 to ensure smooth and unobstructed material conveying. The top of the spiral blades 3 is connected to the lifting motor, and a shaft-mounted reducer is directly connected to the spiral shaft to drive the rotation of the spiral blades 3 to lift materials. The top of the U-shaped trough 2 has a downward-opening sand discharge port.

[0028] The top of the box body 1 is provided with a box opening, and the end of the box opening that connects with the U-shaped groove 2 is a tapered structure with a narrow opening. The part of the box bottom that connects with the U-shaped groove 2 is also a tapered structure.

[0029] The upper part of the U-shaped groove adopts a closed structure, and the top is covered with a semi-circular sealing plate or a straight sealing plate, which can prevent mud and sand from splashing out during operation.

[0030] An overflow trough 4 is provided on the side of the tank opening away from the frame. The top sides of the two side walls of the overflow trough 4 have triangular toothed grooves. The length of the overflow trough 4 is parallel to the side of the tank opening away from the frame. A gap of 10-30 mm is maintained between the overflow trough 4 and the side of the tank opening to allow water to flow in from both sides of the overflow trough 4. A water outlet 5, connected to the overflow trough 4 and located at one end of the overflow trough 4, is provided on one side of the tank body 1. A water inlet pipe 6, fixed relative to the tank body 1, is centrally located on the side of the overflow trough 4 near the spiral blade 3. The water inlet pipe 6 is vertically arranged, and a water inlet is located at its bottom end.

[0031] Regarding the fixing method, some similar devices typically have a mounting bracket 7 erected on the opening of the overflow tank 4 on one side. This example adopts a simplified structure, namely, using a letter-shaped clamp structure to fix the water inlet pipe 6 in the middle of the overflow tank 4. The specific structure includes two semi-circular sub-clamp plates 8 and a female clamp plate 9. The sub-clamp plates 8 and the female clamp plates 9 are semi-circular arc-shaped plate structures arranged opposite each other. The sub-clamp plates 8 have sub-ear plates 10 on both sides, and the female clamp plates 9 have female ear plates 11 on both sides. The sub-ear plates 10 and female ear plates 11 are fastened with bolts to clamp and secure the water inlet pipe 6. The outer side of the female ear plate 11 has an L-shaped folding plate integrally formed with it. The folding plate is fixed to the side wall of the overflow tank 4 with bolts, thereby simply fixing the water inlet pipe 6 in the middle position on one side of the overflow tank 4, and ensuring that there is a distance of not less than 15cm between the water inlet pipe 6 and the side wall of the overflow tank 4, so as not to affect the flow of water into the overflow tank 4.

[0032] Under the above structure, the sand-water mixture is fed into the water tank through the inlet pipe 6 at the top of the tank 1. The heavier particles in the mixture, such as sand, will settle at the bottom of the trough. Driven by the spiral blades 3, the sand particles are lifted along the bottom of the inclined U-shaped trough 2. After leaving the liquid surface, they continue to move a distance. After the sand particles are fully dehydrated, they are discharged into the sand collection bucket through the sand discharge port. The water separated from the sand is collected from the overflow tank 4 and discharged through the outlet 5, thus achieving the separation purpose.

[0033] In terms of improvements, the main method relies on the deflector plate 12 to buffer and block the rushing water flow.

[0034] Below the water inlet is a guide plate 12. The guide plate 12 is an inclined plate. The side of the guide plate 12 closer to the overflow trough 4 is the higher side, and the side of the guide plate 12 closer to the frame is the lower side. The guide plate 12 is inclined downward in a straight line away from the overflow trough 4.

[0035] The upper side of the guide plate 12 is provided with an integrally formed and fixedly connected mounting plate 13. The mounting plate 13 is set upright. The mounting plate 13 and the guide plate 12 are obtained by bending process. The guide plate 12 and the mounting plate 13 have an included angle of 100° to 120°.

[0036] The mounting plate 13 is provided with multiple first double-ended bolts. The first double-ended bolts pass through the side wall of the overflow groove 4 away from the water inlet pipe 6, thereby fixing the mounting plate 13 to the overflow groove 4, so as to achieve convenient installation and disassembly and convenient and flexible use.

[0037] The guide plate 12 has through holes 14 near its two side edges. A vertically mounted pull rod 15 runs through the through holes 14. A stop block 16 is fixed to the bottom of the pull rod 15 by welding. The stop block 16 is larger than the through hole 14 and cannot pass through it. An angle plate 17 is provided on the upper part of the pull rod 15. A second double-ended bolt runs through the angle plate 17. The second double-ended bolt quickly fixes the angle plate 17 to the side of the overflow trough 4 near the water inlet pipe 6, thereby fixing it to both sides of the overflow trough 4 with the mounting plate 13. A large nut 18 is fixed to the angle plate 17 and runs through it. The large nut 18 is threaded to the pull rod 15 (the pull rod 15 is machined using a screw and has external threads on its surface). By rotating the pull rod 15, the relative height of the pull rod 15 with respect to the angle plate 17 can be adjusted, and the stop block 16 can support the guide plate 12. Under the long-term impact of water flow, the guide plate 12 will be subjected to vertical force and deform under long-term stress, increasing the tilt angle and reducing the flow obstruction effect. Therefore, the state of the guide plate 12 can be solidified and strengthened by the tie rod 15, and the height of the tie rod 15 can be adjusted to adapt to the state of the guide plate 12 under different tilt angles and installation heights, making it highly applicable.

[0038] Based on the above structure, the guide plate 12 can be quickly and easily installed on the side of the overflow tank 4 away from the inlet via the mounting plate 13, allowing the coverage area of ​​the guide plate 12 to align with the overflow tank 4, effectively increasing the flow obstruction range. The inclined state is fixed by the tie rod 15, thus ensuring fatigue-free operation over extended periods. The slight inclination of the guide plate 12 not only hinders the downward impact of the fluid in the vertical direction, blocking most of the direct impact of the water flow, but also creates a relatively stable flow state within the separator. The inclined guide plate 12 helps guide the water flow along the designed path, reducing interference with the sediment separation process. Simultaneously, it prevents gravel from accumulating on the guide plate 12, reducing the burden of maintenance and cleaning.

[0039] In some other existing equipment, a baffle plate 12 is installed at the water inlet. After a period of time, silt will accumulate on the baffle plate 12. Especially when dealing with sandy water with high sand content, it was found in the initial improvement that sand and gravel easily accumulate on both sides, resulting in uneven water flow. By using the inclined baffle plate 12, combined with the continuous falling water flow, the baffle plate 12 is constantly flushed. With long-term use, the problem of sand accumulation does not need to be frequently maintained, and the water flow can be evenly distributed.

[0040] Example 2:

[0041] In this example, the structure of the box 1, U-shaped groove 2, spiral blade 3, overflow groove 4, and water inlet pipe 6 is the same as that of Embodiment 1. On the basis of the structure of Embodiment 1, the dispersion of the impact water flow is achieved by the cooperation of the guide plate 12 and the guide cylinder 19.

[0042] A guide tube 19 is also provided on the lower side of the guide plate 12. The guide tube 19 is a cylindrical straight tube with its axis parallel to the overflow channel 4. The two ends of the guide tube 19 are fixed with a cylinder shaft 20 coaxially. The bottom side of the guide plate 12 is set lower than the top side of the guide tube 19, so that the sand and gravel cannot pass over the guide tube 19, but only the water flow can pass over the guide tube 19. Therefore, the guide tube 19 is located on the bottom side of the guide plate 12, which has the dual effect of further dispersing and buffering the water flow slightly downward guided by the guide plate 12 and separating sand and water.

[0043] The guide tube 19 has upright plates 21 on both sides. The bottom of the upright plate 21 is used to connect and fix it to the tube shaft 20. The upright plate 21 is a long strip plate that is set vertically. The top of the upright plate 21 is fixed with a horizontal plate 22 perpendicular to it. A beam frame 23 is provided between the two horizontal plates 22 and fixedly connected to them. The beam frame 23 fixes the two horizontal plates 22 into a whole and enhances the stability of the overall structure, avoiding deformation during installation and use.

[0044] The horizontal plate 22 extends outward horizontally, and a downward-extending portal groove 242U is fixed on the outer side of the horizontal plate 22 away from the guide tube 19. The portal groove 242U is a through groove that passes through both sides. The width of the portal groove 242U is adapted to the thickness of the side wall of the tank 1. Therefore, the portal groove 242U can be movably inserted downward into the edge of the tank opening (top side of the side wall of the tank 1) to achieve quick placement of the guide tube 19. The guide tube 19 can be fixed by its own weight, and the force of the water flow through the guide plate 12 is limited. Simple placement can keep the guide tube 19 stationary. This structure is the simplest and most usable. It allows for convenient adjustment of the distance between the guide tube 19 and the guide plate 12, and also allows for quick and flexible selection.

[0045] By combining the guide tube 19 and the guide plate 12, sediment and water can be separated more effectively. The top of the guide tube 19 is slightly higher than the bottom of the guide plate 12, forming a "hydraulic barrier." Only fluids with lower density and less inertia can pass over the top of the guide tube 19 and enter the upper region; high-density particles such as sand and gravel, due to their greater inertia, are difficult to deflect upwards with the streamline and are confined to the region below the guide tube 19. This improves separation efficiency and achieves highly efficient sedimentation, which is better than natural sedimentation. The dual slow-flow design reduces the direct impact of water flow on sediment and lowers the probability of sediment dispersion.

[0046] Example 3:

[0047] Based on Embodiment 2, in order to facilitate the adjustment of the height of the guide tube 19 and to strengthen the fixation of the guide tube 19, strip-shaped components 25 are fixed on both sides of the box opening. The strip-shaped components 25 are welded or bolted to the upper side of the side wall of the box body 1. The strip-shaped components 25 are long strip components made of square steel or other square cross sections. The strip-shaped components 25 are used to fix the guide tube 19.

[0048] The horizontal plate 22 extends horizontally outward. A downward-extending portal groove 242U is fixed to the outer side of the horizontal plate 22 away from the guide tube 19. The width of the portal groove 242U is adapted to the thickness of the side wall of the housing 1 where the strip member 25 is installed. The portal groove 242U is a through groove extending through both sides, allowing it to be inserted downwards into the outside of the strip member 25 and movably connected to the strip member 25 and the side wall of the housing 1 to which it is fixed. Two upper threaded sleeves 27 are fixed on the horizontal plate 22, passing through it. The upper threaded sleeves 27 are located near the edge of the horizontal plate 22, and an upright support screw 26 is threaded into the upper threaded sleeve 27. The bottom end of the support screw 26 rests on the top side surface of the strip member 25, thereby adjusting the height of the guide tube. A side threaded sleeve 29 extends through the outer side of the portal groove 242U near the bottom. A fastening screw 28 is threaded into the inner thread of the side threaded sleeve 29. The inner end of the fastening screw 28 abuts against the outer side of the strip 25, or against the side wall of the housing 1. Depending on the height supported by the supporting screw 26, the fixing screw can assist in reinforcing and limiting the portal groove 242U through its inner end. If the guide tube 19 adopts a hollow thin-walled structure (considering advantages such as material saving and ease of handling, a hollow thin-walled tube structure is also a good choice), the fastening screw 28 can be used to further enhance the limiting effect.

[0049] Example 4:

[0050] In this example, the structure of the box 1, U-shaped groove 2, spiral blade 3, overflow groove 4, and water inlet pipe 6 is the same as that of Embodiment 1. On the basis of the structure of Embodiment 1, the dispersion of the impact water flow is achieved by the cooperation of the guide plate 12 and the slowly rotating guide cylinder 19.

[0051] Unlike embodiments 2 and 3 above, the cylindrical shaft 20 is rotatably connected to the bottom side of the vertical plate 21. Other structures are based on embodiments 3 or 2, but with a lower sprocket 31 fixed on one side of the cylindrical shaft 20, and a stepper motor fixedly mounted on the horizontal plate 22 on the same side. The output shaft of the stepper motor is connected to an upper sprocket 30 via a reducer. The upper sprocket 30 and the lower sprocket 31 are driven by a chain, causing the guide cylinder to rotate slowly downwards towards the guide plate. Figure 6In the example, the rotation is counterclockwise, with a speed of 2 to 6 rpm. Slow counterclockwise rotation generates a tangential flow opposite to the direction of the incoming water impact, which helps to counteract turbulence and stabilize the flow field. From a fluid dynamics perspective, the counterclockwise rotating guide tube 19 forms a rotating boundary layer around itself, which can partially counteract the clockwise or rightward disturbances brought by the incoming water; it enhances local turbulence and helps prevent fine particles from depositing on the tube wall.

[0052] The guide vane 12 changes the main direction of the incoming water from vertical to oblique, reducing direct interference with the spiral conveying zone. The guide tube 19 further guides the water flow to form two zones: inner and outer. Below the guide tube 19 (settling zone): the water flow velocity is low and the flow is stable; sand and gravel particles settle due to gravity and are not easily carried to the top; the weak shear flow generated by the rotation of the guide tube 19 can prevent particle accumulation (no maintenance is required, and sedimentation problems can be avoided by automatic rotation), and promote movement to the spiral conveying zone.

[0053] Above the guide tube 19 (clear water zone): Only liquid flow carrying fine particles can pass through the guide tube 19; achieving preliminary "hydraulic classification". Slowly pushing to the left promotes the entry of clear water into the overflow tank 4.
