Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically an industrial wastewater sedimentation treatment device. Background Technology

[0002] In the field of industrial wastewater treatment, sedimentation separation is one of the important steps in removing suspended particulate matter from wastewater; Currently, some wastewater treatment devices based on principles such as gravity sedimentation, centrifugal separation, and chemical flocculation have appeared on the market. However, these devices often suffer from problems such as complex structure and inconvenient maintenance in practical applications. For example, after prolonged use, sludge will adhere to the equipment, requiring manual cleaning, otherwise it will affect the equipment's working efficiency. In addition, some devices are not well designed to classify and settle particles by size in terms of treatment efficiency and adaptability, nor do they have good adjustments to the sedimentation structure to address water quality issues, thus failing to improve sedimentation efficiency.

[0003] Therefore, we have made improvements to this and proposed an industrial wastewater sedimentation treatment device, which aims to remove residual fine suspended particles and colloidal substances (such as flocs formed by coagulation reaction) in the water, providing conditions for subsequent advanced treatment such as filtration and membrane separation. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing industrial wastewater sedimentation treatment devices being complex in structure, inconvenient to maintain, and having limited adaptability to different water qualities.

[0005] To achieve the above-mentioned objectives and improve the above-mentioned problems, this utility model provides an industrial wastewater sedimentation treatment device, including a sedimentation unit and a separation unit. The upper part of the sedimentation unit is provided with a water inlet assembly, and the separation unit is located inside the sedimentation unit. The separation unit and the sedimentation unit are connected by an adjusting component, which is used to adjust the position of the separation unit inside the sedimentation unit to adapt to different wastewater treatment needs. The bottom of the separation unit is provided with a sludge discharge assembly.

[0006] The separation unit includes a rotating disk and multiple separation plates. A drive shaft is located at the center of the rotating disk. The drive shaft passes through the top of the settling unit and is connected to an external motor. The separation plates are evenly distributed on the outer periphery of the rotating disk. Each separation plate has several through holes on its surface. The diameter of the through holes gradually increases from the center of the separation plate outward. A sludge scraper is located at the lower end of the separation plate. The sludge scraper contacts the inner wall of the settling unit.

[0007] As a preferred technical solution of this application, the water inlet assembly includes a water inlet pipe and a diverter. One end of the water inlet pipe is connected to the top of the sedimentation unit, and the other end is fixedly connected to the diverter. The bottom of the diverter is provided with multiple water outlets, which are evenly distributed along the circumference of the diverter.

[0008] As a preferred technical solution of this application, the adjusting component includes a support rod and a positioning block. One end of the support rod is fixedly connected to the outside of the separation unit, and the other end is threadedly connected to the positioning block. The positioning block is embedded in the inner wall of the settling unit and slides with it. A locking bolt is provided on the outside of the positioning block, and the locking bolt is used to fix the position of the positioning block.

[0009] As a preferred technical solution of this application, the sludge discharge assembly includes a sludge collection hopper and a sludge discharge pipe. The sludge collection hopper is fixed at the bottom center of the separation unit. One end of the sludge discharge pipe is connected to the sludge collection hopper, and the other end extends to the outside of the settling unit.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: By incorporating a separation unit and an adjusting mechanism, the rotating disk in the separation unit drives the separation plate to rotate. The through-hole design on the separation plate allows for graded sedimentation based on particle size, thereby improving sedimentation efficiency. Simultaneously, the adjusting mechanism allows the separation unit to move up and down within the sedimentation unit to adapt to different water quality treatment requirements. The distributor in the inlet assembly evenly distributes wastewater within the sedimentation unit, preventing concentrated water flow from impacting a single area and thus improving overall treatment effectiveness. The sludge removal assembly is linked to the separation unit via a transmission mechanism. As the separation plate rotates, scraper strips scrape sludge deposited on the inner wall of the sedimentation unit into a sludge collection hopper, which is then discharged through a sludge discharge pipe, reducing manual cleaning workload. The baffle plate design extends the residence time of wastewater within the sedimentation unit, further improving sedimentation efficiency. In summary, this invention solves the problems of complex structure, inconvenient maintenance, and limited adaptability to different water qualities in existing sedimentation devices.

[0015] This utility model provides an industrial wastewater sedimentation treatment device, the overall structure of which is as follows: Figure 1-4 As shown, the system includes a settling unit 1, a separation unit 2, a water inlet assembly 3, an adjusting component 4, and a sludge discharge assembly 5. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] The settling unit 1 is the main body of the device, with a cylindrical structure. The separation unit 2 is located inside the settling unit 1, connected by an adjusting member 4, and can move up and down to adapt to the treatment requirements of different water qualities. The specific structure of the adjusting member 4 is as follows: Figure 4 As shown, the system includes a support rod 14 and a positioning block 15. One end of the support rod 14 is fixedly connected to the outside of the separation unit 2, and the other end is threadedly connected to the positioning block 15. The positioning block 15 is embedded in the inner wall of the settling unit 1 and slides against it. A locking bolt 16 is provided on the outside of the positioning block 15 to fix its position. When it is necessary to adjust the height of the separation unit 2, the locking bolt 16 is loosened, the positioning block 15 is slid along the inner wall of the settling unit 1 to the target position, and then it is tightened again.

[0017] The composition of separation unit 2 is as follows Figure 2As shown, the system includes a rotating disk 6 and multiple separating plates 7. A drive shaft 8 is located at the center of the rotating disk 6, passing through the top of the settling unit 1 and connected to an external motor. The external motor drives the drive shaft 8 to rotate, thereby driving the rotating disk 6 to rotate. The separating plates 7 are evenly distributed on the outer periphery of the rotating disk 6. Each separating plate 7 has several through holes 9 on its surface, with the diameter of the through holes 9 gradually increasing from the center of the separating plate 7 outwards. This design allows smaller particles to settle near the center, while larger particles settle further away from the center, achieving a graded settling effect. A scraper strip 10 is located at the lower end of the separating plate 7, contacting the inner wall of the settling unit 1. The scraper strip 10 is made of corrosion-resistant rubber to ensure it will not fail due to corrosion during long-term use.

[0018] The inlet assembly 3 is located at the top of the settling unit 1 and includes an inlet pipe 11 and a distributor 12. One end of the inlet pipe 11 is connected to the top of the settling unit 1, and the other end is fixedly connected to the distributor 12. The bottom of the distributor 12 is provided with multiple outlets 13, which are evenly distributed along the circumference of the distributor 12, so that the wastewater can be evenly distributed into the interior of the settling unit 1, avoiding the water flow from concentrating and impacting a certain area, thereby improving the overall treatment effect.

[0019] The sludge discharge assembly 5 is located at the bottom of the separation unit 2 and includes a sludge collection hopper 17 and a sludge discharge pipe 18. The sludge collection hopper 17 is fixed at the center of the bottom of the separation unit 2. One end of the sludge discharge pipe 18 is connected to the sludge collection hopper 17, and the other end extends to the outside of the settling unit 1. A sludge collection box 19 is provided in the middle of the sludge discharge pipe 18. The transmission mechanism includes a support frame 20 and a coupling 21. The external motor is fixedly connected to the inside of the support frame 20, and the drive shaft 8 is fixedly connected to the output shaft of the external motor through the coupling 21.

[0020] Baffles 22 are installed on the inner wall of the settling unit 1, and are staggered along the height direction of the settling unit 1. The surface of the baffles 22 is coated with an anti-corrosion coating with a thickness of 0.5 mm to 1 mm. The design of the baffles 22 extends the residence time of wastewater in the settling unit 1, while the application of the anti-corrosion coating enhances the durability and corrosion resistance of the device.

[0021] The wastewater treatment process is as follows: Wastewater enters the distributor 12 through the inlet pipe 11 and is evenly distributed into the sedimentation unit 1 through the outlet 13. Under the action of the baffle plate 22, the wastewater forms a tortuous flow path, prolonging the residence time and facilitating particle settling. The rotating disk 6 in the separation unit 2 is driven to rotate by an external motor, causing the separation plate 7 to rotate. The through holes 9 on the separation plate 7 achieve graded sedimentation according to particle size; smaller particles settle near the center, while larger particles settle further away. The sludge scraper 10 scrapes the sludge deposited on the inner wall of the sedimentation unit 1 into the sludge collection hopper 17, and the sludge is discharged through the sludge discharge pipe 18. The height of the separation unit 2 can be adjusted by the adjusting component 4 to adapt to different water quality treatment requirements, improving the adaptability of the device.

[0022] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0023] In the actual operation of industrial wastewater treatment, the wastewater to be treated is first introduced into the distributor 12 through the inlet pipe 11. The distributor 12 has multiple outlets 13 at its bottom, which are evenly distributed along the circumference of the distributor 12, allowing the wastewater to enter the settling unit 1 at a uniform flow rate. This design avoids the wastewater directly impacting a specific area, thereby reducing the interference of water flow disturbance on particulate matter settling and improving the overall treatment effect. The connection between the distributor 12 and the inlet pipe 11 adopts a fixed structure to ensure the stability of the wastewater flow path.

[0024] After entering the settling unit 1, the wastewater forms a tortuous flow path under the action of the baffles 22. The baffles 22 are staggered along the height of the settling unit 1, and their surfaces are coated with an anti-corrosion coating with a thickness of 0.5 mm to 1 mm. This design not only prolongs the residence time of the wastewater in the settling unit 1 but also enhances the durability and corrosion resistance of the device. Guided by the baffles 22, the wastewater flows slowly along the inner wall, and the particles gradually settle to the bottom under gravity. The design of the baffles 22 effectively reduces the water flow velocity, providing sufficient time for particle settling.

[0025] Meanwhile, the rotating disk 6 in the separation unit 2 is driven to rotate by an external motor, which in turn drives the separation plate 7 to rotate. The surface of the separation plate 7 has several through holes 9, the diameter of which gradually increases from the center outwards. When the separation plate 7 rotates, smaller particles are deposited closer to the center due to less centrifugal force, while larger particles are deposited further away from the center due to greater centrifugal force. This staged sedimentation design achieves effective separation of particles of different sizes, significantly improving sedimentation efficiency. A scraper 10 is located at the lower end of the separation plate 7, and the scraper 10 is in close contact with the inner wall of the sedimentation unit 1. As the separation plate 7 rotates, the scraper 10 scrapes the sludge deposited on the inner wall of the sedimentation unit 1 into the sludge collection hopper 17, preventing sludge accumulation from affecting the normal operation of the device.

[0026] The sludge discharge assembly 5 is linked to the separation unit 2 via a transmission mechanism. The sludge collection hopper 17 is fixed at the bottom center of the separation unit 2, and the sludge is discharged from the sludge collection hopper 17 through the sludge discharge pipe 18 to the outside of the settling unit 1.

[0027] In addition, the adjusting component 4 is used to adjust the position of the separation unit 2 inside the settling unit 1. One end of the support rod 14 is fixedly connected to the outside of the separation unit 2, and the other end is threadedly connected to the positioning block 15. The positioning block 15 is embedded in the inner wall of the settling unit 1 and slides against it. When it is necessary to adapt to the treatment requirements of different water qualities, the locking bolt 16 is loosened, the positioning block 15 is slid along the inner wall of the settling unit 1 to the target position, and then it is tightened again. This design allows the separation unit 2 to flexibly adjust its height according to actual needs, thereby improving the adaptability of the device to different water qualities.

[0028] By combining the above steps and principles, this invention achieves efficient separation and sedimentation of suspended particulate matter in industrial wastewater, solving the problems of complex device structure, inconvenient maintenance, and limited adaptability to different water qualities in existing technologies. The entire device has a high degree of automation, reducing manual intervention and maintenance workload.
