Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a vertical flow sedimentation wastewater treatment device. Background Technology
[0002] Currently, vertical flow sedimentation tanks are widely used in wastewater treatment processes to separate suspended particles in water using the principle of gravity settling. Traditional vertical flow sedimentation tanks rely on the uniform settling of water from top to bottom, allowing suspended solids to slowly sink to the bottom of the equipment in the settling zone, where the sludge is then discharged through a sludge removal system. However, the following problems often arise in practical applications:
[0003] When the concentration of suspended solids in wastewater is high, the load on the sedimentation zone increases, which can easily lead to the generation of a large amount of sludge during the sedimentation process and local accumulation in the tank, resulting in blockage and reducing the equipment's processing efficiency and continuous operation capability. Traditional sedimentation tanks cannot achieve dynamic control of water flow distribution when faced with changes in suspended solids concentration under different operating conditions, making it difficult to achieve the best sedimentation effect under both high and low load conditions, resulting in insufficient process adaptability.
[0004] Therefore, we propose a vertical flow sedimentation wastewater treatment device to solve the existing problems. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a vertical flow sedimentation wastewater treatment device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical flow sedimentation wastewater treatment device, comprising an inlet pipe, a tank, a central pipe, and a shaft head. The inner wall of the upper end of the tank is provided with an inner ring, and the inner wall of the inner ring and the inner wall of the upper end of the tank form a drainage trough. An outlet is provided on the drainage trough. The central pipe is located at the center of the tank. The inlet pipe is located on the tank and extends into the central pipe. One end of the inlet pipe is located at the center pipe and opens upward. A shaft head is provided directly below the central pipe through a connecting assembly. The connecting assembly is used to control the rotation of the shaft head. Four reflectors are equidistantly arranged on the shaft head, and the four reflectors have different tilt angles.
[0007] Preferably, the connecting assembly consists of a connecting rod, a reflector, a connecting seat, and a base block. The connecting seat is located on the outer wall of the central tube, the top end of the connecting rod is located on the outer wall of the connecting seat, and the base block is located at the bottom end of the connecting rod.
[0008] Preferably, the shaft head is rotatably mounted on the base block, and the base block contains a motor structure, with the output end of the motor connected to the shaft end of the shaft head.
[0009] Preferably, the outer wall of the shaft head is provided with fixed arms at equal intervals, the reflector plate is provided with a screw, the screw passes through the fixed arm and the bottom end of the screw is threaded with a nut.
[0010] Preferably, the upper outer wall of the central tube is provided with a base frame, the circumferential edge of the base frame is provided on the upper surface of the inner ring, and the top end of the central tube is provided with a cap.
[0011] Preferably, a mud discharge pipe is embedded at the lower end of the tank.
[0012] Preferably, the upper surface of the inner ring is lower than the upper surface of the tank body, and the water outlet is lower than the upper surface of the inner ring.
[0013] Preferably, the lower end of the outer wall of the tank is provided with a support ring, and four support legs are provided at equal intervals on the lower surface of the support ring.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In the process of using this vertical flow sedimentation wastewater treatment device, the wastewater to be treated enters the central pipe through the inlet pipe and then falls from the central pipe. Under the action of the reflector, the vertical downward water flow is transformed into a horizontal direction, so that the water flow is evenly distributed throughout the sedimentation zone. Due to the low water flow velocity, the suspended particles in the water gradually settle under the action of gravity. The sludge that settles into the tank is concentrated at the lowest point inside the tank. At this time, the sludge is connected to an external sludge pump through the sludge discharge pipe. A negative pressure is formed in the sludge discharge pipe to suck out and discharge the sludge. The water that has been settled overflows into the water collection tank and is finally discharged through the outlet.
[0016] Furthermore, by connecting to an external power source, the motor drives the shaft to rotate, thereby controlling the reflector with the required tilt angle to be vertically upward and directly below the central tube, changing the direction and distribution of the water flow, so that the water flows into the sedimentation zone more evenly. The tilt angle of the reflector is the degree of inclination of the reflector's inclined surface.
[0017] When the concentration of suspended solids is high, the sedimentation zone is under heavy load, which can easily lead to sludge accumulation and blockage. In this case, increasing the tilt angle of the reflector plate, i.e., making the reflector plate slope gently, disperses the water flow, extends the settling path of suspended solids, thereby improving the treatment capacity of the sedimentation zone and preventing sludge accumulation.
[0018] When the concentration of suspended solids is low, reducing the tilt angle of the reflector, i.e., making the reflector slope steep, concentrates the water flow and accelerates the settling speed of suspended solids;
[0019] This invention adapts to different operating conditions with varying suspended solids concentrations by adjusting the tilt angle of the reflector. When the suspended solids concentration is high, the sedimentation zone is under heavy load, making it prone to sludge accumulation and blockage. The device increases the tilt angle of the reflector to create a gentle slope, dispersing the water flow and extending the settling path of suspended particles, thereby improving the treatment capacity of the sedimentation zone and preventing excessive sludge accumulation in certain areas. When the suspended solids concentration is low, the tilt angle of the reflector is reduced to create a steep slope, concentrating the water flow and accelerating the settling speed of suspended solids, ensuring treatment efficiency.

[0028] Example 1
[0029] like Figures 1-5As shown, the present invention proposes a vertical flow sedimentation wastewater treatment device, including an inlet pipe 4, a tank 6, a central pipe 10, and a shaft head 15. The central pipe 10 is located at the center of the tank 6. The inlet pipe 4 is located on the tank 6 and extends into the central pipe 10. One end of the inlet pipe 4 is located on the central pipe 10 and opens upward. The shaft head 15 is located directly below the central pipe 10 via a connecting assembly. The connecting assembly is used to control the rotation of the shaft head 15. Four reflectors 12 are equidistantly arranged on the shaft head 15, and the four reflectors 12 have different inclination angles. The wastewater to be treated enters the central pipe 10 through the inlet pipe 4 and then falls from the central pipe 10. Under the action of the reflectors 12, the vertical downward water flow is changed to a horizontal direction, so that the water flow is evenly distributed throughout the sedimentation zone. Due to the low water flow velocity, the suspended particles in the water gradually settle under the action of gravity. The sludge that settles into the tank 6 is concentrated at the lowest point inside the tank 6.
[0030] A sludge discharge pipe 3 is embedded at the lower end of the tank body 6. An external sludge discharge pump is connected through the sludge discharge pipe 3, and a negative pressure is formed in the sludge discharge pipe 3 to suck out and discharge the sludge.
[0031] The inner wall of the upper end of the tank body 6 is provided with an inner ring 9. The inner wall of the inner ring 9 and the inner wall of the upper end of the tank body 6 form a drainage trough. The drainage trough is provided with an outlet 5. The upper surface of the inner ring 9 is lower than the upper surface of the tank body 6, and the outlet 5 is lower than the upper surface of the inner ring 9. The water that has settled overflows into the water collection tank and is finally discharged through the outlet 5.
[0032] The upper outer wall of the central tube 10 is provided with a base frame 7, the circumference of the base frame 7 is located on the upper surface of the inner ring 9, and the top of the central tube 10 is provided with a cap 8. Through the design of the cap 8, the cap 8 can be disassembled by thread when needed, which can ensure that the central tube 10 has the ability to pass through.
[0033] Example 2
[0034] like Figures 1-5 As shown, the wastewater treatment device for a vertical flow sedimentation tank proposed in this utility model, compared with Embodiment 1, further includes: a connecting assembly consisting of a connecting rod 11, a reflector plate 12, a connecting seat 13, and a base block 14.

A motor structure is provided inside the base block 14, and the output end of the motor is connected to the shaft end of the shaft head 15. An external power supply is connected to the motor, which drives the shaft head 15 to rotate, thereby controlling the reflector plate 12 with the required tilt angle to be vertically upward and directly below the central tube 10. The tilt angle of the reflector plate 12 is the degree of inclination of the slope of the reflector plate 12. When the suspended solids concentration is high, the tilt angle of the reflector plate 12 is increased, so that the slope of the reflector plate 12 is gentle. When the suspended solids concentration is low, the tilt angle of the reflector plate 12 is decreased, so that the slope of the reflector plate 12 is steep.
