Description

Technical Field

[0001] This invention belongs to the field of wastewater purification technology, specifically referring to a wastewater purification device for water resource environmental protection engineering. Background Technology

[0002] Industrial wastewater, a byproduct of industrial production activities, mainly encompasses two categories: production wastewater and production liquid waste. It specifically refers to liquid waste generated by various industrial enterprises during production processes such as raw material processing, product manufacturing, and equipment cleaning. This type of wastewater generally contains high concentrations of toxic and harmful substances. Among them, heavy metal ions (such as lead, mercury, cadmium, and chromium) have become the most representative pollutants in industrial wastewater due to their stable chemical properties and strong bioaccumulation. If discharged directly without proper treatment, they will cause irreversible damage to aquatic ecosystems, soil environments, and human health.

[0003] The existing wastewater purification equipment used in water resource environmental protection projects has the following problems:

[0004] Existing wastewater purification equipment used in water resource environmental protection projects lacks the ability to accelerate the settling of sediments formed in wastewater while ensuring their integrity. This results in a large amount of sediment flowing into the filtration system with the water flow, reducing the filtration efficiency and filtration rate of the filtration system. Furthermore, traditional wastewater purification equipment used in water resource environmental protection projects also lacks the ability to monitor the flow rate of the filter screen.

[0005] Therefore, it cannot meet the current demand for wastewater purification equipment in water resource environmental protection projects. Summary of the Invention

[0006] In response to the above situation and to overcome the shortcomings of existing technologies, this solution provides a wastewater purification device for water resource environmental protection projects that can accelerate sedimentation while ensuring the integrity of the sediment and can monitor the flow rate of the filter screen.

[0007] The technical solution adopted in this plan is as follows: This plan proposes a wastewater purification equipment for water resource environmental protection engineering, including an annular box, a filter cylinder, a drainage chamber, a bottom-flush sedimentation mechanism, and a sludge-pressing filtration mechanism. The filter cylinder is located on the inner bottom wall of the annular box, the drainage chamber is located between the annular box and the filter cylinder, the bottom-flush sedimentation mechanism is located on the annular box, and the sludge-pressing filtration mechanism is located on the filter cylinder. The bottom-flush sedimentation mechanism includes a mixing component, a conveying component, and a drainage component. The mixing component is located on the upper wall of the annular box, the conveying component is located on the upper wall of the annular box on one side of the mixing component, and the drainage component is located on the side wall of the annular box. The sludge-pressing filtration mechanism includes a magnetic levitation component, a spiral component, a filtration component, and a filtration measurement component. The magnetic levitation component is located on the bottom inner wall of the filter cylinder, the filtration component is located on the middle inner wall of the filter cylinder, the spiral component is installed through the filtration component, and the filtration measurement component is installed on the magnetic levitation component.

[0008] As a further preferred embodiment of the present invention, the mixing assembly includes a dosing valve and a wastewater valve. The dosing valve is connected to the upper wall of the annular tank, and the wastewater valve is connected to the upper wall of the annular tank on one side of the dosing valve. The conveying assembly includes a conveying pump and a water delivery pipe. Multiple sets of the conveying pumps are located on the upper wall of the annular tank, with the pump's suction end penetrating inside the annular tank. The water delivery pipe is connected between the upper wall of the filter cartridge and the pump's discharge end. The drainage assembly includes a drain valve, a drain pipe, and a drain trough. The drain valve is connected to the bottom side wall of the filter cartridge. The drain pipe penetrates the inner wall of the annular tank and communicates with the drainage chamber. Multiple sets of the drain troughs are located on the top side wall of the filter cartridge, and the drain troughs are interconnected.

[0009] In use, the sewage pipe is connected to the sewage valve, and the sewage enters the annular tank for storage through the sewage valve. The operator adds chemical agents into the annular tank through the dosing valve to form insoluble hydroxide precipitates of heavy metal ions. The precipitates formed in the sewage are then filtered. The pump draws sewage from the annular tank through the pumping end, and the sewage is transported from top to bottom to the filter cylinder through the water supply pipe for filtration. As the water flows downward, the precipitates in the sewage settle to the bottom of the filter cylinder. The impact force of the water flow gradually weakens from top to bottom, creating a relatively stable sedimentation environment at the bottom of the filter cylinder. As the liquid level inside the filter cylinder rises, the sewage that has undergone sedimentation is discharged into the drainage chamber through the drainage trough. The purified sewage inside the drainage chamber is discharged through the drainage pipe.

[0010] Preferably, the magnetic levitation assembly includes a sludge pressing box, an annular electromagnet, a floating magnetic ring, a rubber pad, and a sludge pressing frame. The sludge pressing box is located on the inner wall of the bottom of the filtrate cylinder and has an opening at the top. The annular electromagnet is located on the upper wall of the sludge pressing box. The floating magnetic ring is slidably located on the inner wall of the filtrate cylinder above the annular electromagnet. The rubber pad is located on the upper wall of the annular electromagnet. The sludge pressing frame is located on the inner wall of the floating magnetic ring, with one end of the sludge pressing frame away from the floating magnetic ring extending into the sludge pressing box, and its outer diameter matching the inner diameter of the sludge pressing box. The spiral assembly includes a stirring motor, a drive shaft, and spiral blades. The stirring motor is located on the upper wall of the filtrate cylinder, and the drive shaft is rotatably located on the top wall of the filtrate cylinder. The power end of the stirring motor passes through the filtrate cylinder and is connected to the drive shaft. The rotary blades are located at the end of the drive shaft away from the agitator motor; the filter assembly includes a filter frame, a carrier plate, a filter screen, and a telescopic tube. The filter frame is slidably mounted on the inner wall of the filtrate cylinder, and the bottom wall of the filter frame is connected to the upper wall of the floating magnetic ring. The carrier plate is located on the inner wall of the filter frame outside the drive shaft. Multiple sets of filter screens are located between the filter frame and the carrier plate. The telescopic tube passes through the carrier plate and is located on the side of the water delivery pipe away from the delivery pump; the filter measuring assembly includes a distance sensor, a distance measuring port, and a sensing column. The distance sensor is installed through the upper wall of the sludge pressing frame. The distance measuring port is located between the bottom wall of the sludge pressing frame and the distance measuring end of the distance sensor. The sensing column is located on the bottom wall of the sludge pressing box. The sensing column, the distance sensor, and the distance measuring port are coaxially and vertically arranged.

[0011] During use, wastewater containing sediment inside the water supply pipe flows into the filter cylinder below the filter screen through the telescopic pipe. To avoid strong water flow impact force dispersing the sediment and forming a large number of small sediments that would affect the sedimentation effect, the pumping speed of the wastewater inside the annular tank is slowed down, thus reducing the impact force when the wastewater containing sediment enters the filter cylinder. At this time, to ensure that the sediment can quickly settle to the bottom of the filter cylinder, the power end of the agitator motor drives the drive shaft to rotate, and the drive shaft drives the spiral blades to rotate. The low-speed rotation of the spiral blades creates a weak vortex in the wastewater below the filter screen, providing a downward thrust for the sediment to settle. The weak vortex can only affect a local area below the filter screen, thus ensuring that a stable sedimentation environment is formed at the bottom of the filter cylinder, which can both ensure that the sediment is not dispersed by the water flow and accelerate the sedimentation speed.

[0012] Initially, the bottom wall of the floating magnetic ring is in contact with the upper wall of the rubber pad. The annular electromagnet is energized and generates magnetism. The annular electromagnet and the floating magnetic ring are set with the same pole. The annular electromagnet is fixed to the upper wall of the sludge pressing box and pushes the floating magnetic ring through repulsion. The floating magnetic ring slides along the inner wall of the filtrate cylinder, causing the sludge pressing frame to rise and extend into the sludge pressing box. After the annular electromagnet is de-energized, the floating magnetic ring, under gravity, causes the sludge pressing frame to descend and enter the sludge pressing box. The sludge pressing frame squeezes the sediment that has settled inside the sludge pressing box. On the one hand, this reduces the probability of the sediment flowing with the water flow, improving the filtration efficiency and filtration rate of the filter screen for sewage. On the other hand, it reduces the volume and water content of the sludge, achieving sludge reduction. After being filtered by the filter screen, the sewage rises to the upper part of the filtrate cylinder. The purified sewage in the upper part of the filtrate cylinder is discharged into the filtrate cylinder through the drainage trough.

[0013] The annular electromagnet is intermittently energized to push the floating magnetic ring. The floating magnetic ring resets under gravity and adheres to the rubber pad. When the filter screen becomes clogged, its flow rate decreases, and the filter screen is pushed by the rising water flow and cannot reset. At this time, the ranging sensor detects the change in distance between itself and the sensing column through the ranging port, which helps to remind the operator to replace or clean the filter screen.

[0014] Specifically, a controller is provided on the upper wall of the annular box.

[0015] The controller is electrically connected to the delivery pump, the ring electromagnet, the agitator motor, and the ranging sensor.

[0016] The beneficial effects achieved by this solution using the above structure are as follows:

[0017] Compared with existing technologies, this solution combines a bottom-flush sedimentation mechanism with a sludge-pressing filtrate mechanism. Through the inclusion of mixing, conveying, drainage, magnetic levitation, spiral, filtering, and filtration measurement components, it can perform swirling separation of sediments formed in wastewater. Under the indirect energization of a ring electromagnet, the floating magnetic ring drives the sludge press frame to move up and down, squeezing the sediments settled inside the sludge press tank, reducing the probability of sediments flowing with the water flow. Furthermore, the monitoring of the sludge press frame's reset position by a distance sensor ensures the filtration performance of the filter screen, thereby improving the purification efficiency and rate of wastewater. The sludge press frame's compression of the sediments inside the sludge press tank reduces the probability of sediments flowing with the water flow, improving the filtration efficiency and rate of the filter screen; it also reduces the volume and water content of the sludge, achieving sludge reduction. After filtration, the wastewater rises to the upper part of the filtrate cylinder, and the purified wastewater at the top of the filtrate cylinder is discharged through a drainage trough.

[0033] The mixing assembly 5 includes a dosing valve 6 and a wastewater valve 7. The dosing valve 6 is connected to the upper wall of the annular box 1, and the wastewater valve 7 is connected to the upper wall of the annular box 1 on one side of the dosing valve 6.

[0034] The magnetic levitation assembly 16 includes a sludge pressing box 17, an annular electromagnet 18, a floating magnetic ring 19, a rubber pad 20, and a sludge pressing frame 34. The sludge pressing box 17 is located on the inner wall of the bottom of the filtrate cylinder 2 and has an opening at the top. The annular electromagnet 18 is located on the upper wall of the sludge pressing box 17. The floating magnetic ring 19 is slidably located on the inner wall of the filtrate cylinder 2 above the annular electromagnet 18. The rubber pad 20 is located on the upper wall of the annular electromagnet 18. The sludge pressing frame 34 is located on the inner wall of the floating magnetic ring 19, with one end of the sludge pressing frame 34 extending into the sludge pressing box 17 away from the floating magnetic ring 19, and its outer diameter being the same as the inner diameter of the sludge pressing box 17. The spiral assembly 21 includes a stirring motor 22, a drive shaft 23, and spiral blades 24. The stirring motor 22 is located on the upper wall of the filtrate cylinder 2, and the drive shaft 23 is rotatably located on the top wall of the filtrate cylinder 2. The power end of the stirring motor 22 passes through the filtrate cylinder 2 and is connected to the drive shaft 23. The spiral blades 24 are located on the inner wall of the filtrate cylinder 2. The drive shaft 23 is located away from the end of the agitator motor 22; the filter assembly 25 includes a filter frame 26, a screen plate 27, a filter screen 28, and a telescopic tube 29. The filter frame 26 is slidably disposed on the inner wall of the filtrate cylinder 2, and the bottom wall of the filter frame 26 is connected to the upper wall of the floating magnetic ring 19. The screen plate 27 is disposed on the inner wall of the filter frame 26 outside the drive shaft 23. Multiple sets of filter screens 28 are disposed between the filter frame 26 and the screen plate 27. The telescopic tube 29 passes through the screen plate 27 and is disposed on the side of the water delivery pipe 10 away from the delivery pump 9; the filter measuring assembly 30 includes a distance sensor 31, a distance measuring port 32, and a sensing column 33. The distance sensor 31 is disposed through the upper wall of the sludge pressing frame 34. The distance measuring port 32 is disposed between the bottom wall of the sludge pressing frame 34 and the distance measuring end of the distance sensor 31. The sensing column 33 is disposed on the bottom wall of the sludge pressing box 17. The sensing column 33 is coaxially and vertically arranged with the distance sensor 31 and the distance measuring port 32.

[0035] The upper wall of the annular box 1 is equipped with a controller 35.

[0036] The controller 35 is electrically connected to the delivery pump 9, the annular electromagnet 18, the agitator motor 22, and the distance sensor 31, respectively.

[0037] In practical use, in the initial state, the bottom wall of the floating magnetic ring 19 is attached to the upper wall of the rubber pad 20. The operator connects the sewage pipe to the sewage valve 7, and the sewage enters the annular box 1 for storage through the sewage valve 7. The volume inside the annular box 1 is much larger than the volume inside the filter cylinder 2. Chemical agents are added to the annular box 1 through the dosing valve 6. After standing for a period of time, the heavy metal ions form insoluble hydroxide precipitates. Multiple annular boxes 1 are set up to store a large amount of sewage. A three-way pipe is set at the pumping end of the transfer pump 9. One end of the three-way pipe extends into the current annular box 1, and the remaining connection end of the three-way pipe is connected to other annular boxes 1 through the pipe, thereby meeting the requirements for sewage storage and treatment.

[0038] The sediment formed in the wastewater then needs to be filtered. Controller 35 controls the start of the transfer pump 9, which draws wastewater from inside the annular tank 1 through the pumping end. The wastewater is then transported to the filter cylinder 2 through the water delivery pipe 10 for filtration. The wastewater containing sediment in the water delivery pipe 10 flows into the filter cylinder 2 below the filter screen 28 through the telescopic pipe 29. To avoid the strong water flow impact dispersing the sediment and forming a large number of smaller sediments that would affect the sedimentation effect, the pumping speed of the transfer pump 9 is slowed down, reducing the impact force when the wastewater containing sediment enters the filter cylinder 2. To ensure that the sediment can quickly settle to the bottom of the filter cylinder 2, the controller 35 controls the agitator motor 22 to start. The agitator motor 22 drives the drive shaft 23 to rotate, and the drive shaft 23 drives the spiral blades 24 to rotate. The spiral blades 24 rotate at low speed, causing the sewage below the filter screen 28 to generate a weak vortex, which provides a downward thrust for the sediment to settle. The weak vortex only acts on the local area below the filter screen 28, thereby ensuring that a stable sedimentation environment is formed at the bottom of the filter cylinder 2. This achieves the purpose of both ensuring that the sediment is not dispersed by the water flow and accelerating the sedimentation speed.

[0039] The controller 35 controls the intermittent activation of the annular electromagnet 18. When energized, the annular electromagnet 18 generates magnetism. The annular electromagnet 18 and the floating magnetic ring 19 are aligned with the same pole. The annular electromagnet 18 is fixed to the upper wall of the sludge pressing box 17 and pushes the floating magnetic ring 19 through repulsion. The floating magnetic ring 19 slides along the inner wall of the filtrate cylinder 2, causing the sludge pressing frame 34 to rise and extend into the sludge pressing box 17. After the annular electromagnet 18 is de-energized, the floating magnetic ring 19, under gravity, causes the sludge pressing frame 34 to descend and enter the sludge pressing box 17. The sludge pressing frame 34 then presses the sediment... The sediment inside the sludge pressing box 17 is squeezed, which on the one hand reduces the chance of it flowing with the water flow and improves the filtration efficiency and filtration rate of the filter screen 28 for sewage; on the other hand, it can reduce the volume and water content of the sludge, thereby reducing the amount of sludge. After being filtered by the filter screen 28, the sewage rises to the upper part of the filter cylinder 2. As the liquid level inside the filter cylinder 2 rises, the purified sewage is discharged into the drainage chamber 3 through the drainage trough 14. The purified sewage inside the drainage chamber 3 is discharged through the drainage pipe 13.

[0040] The annular electromagnet 18 is intermittently energized to push the floating magnetic ring 19. The floating magnetic ring 19 resets under gravity and adheres to the rubber pad 20. The controller 35 controls the start of the ranging sensor 31. The ranging sensor 31 measures the distance between itself and the sensing column 33 through the ranging port 32 and uses it as a reference distance. When the filter screen 28 becomes clogged, its flow rate decreases. The filter screen 28 is pushed by the rising water flow and cannot reset. At this time, the ranging sensor 31 detects through the ranging port 32 that the distance between itself and the sensing column 33 has changed to a greater than the reference distance, reminding the operator to replace or clean the filter screen 28 to ensure the flow rate of the filter screen 28.

[0041] An external filter screen is installed on the outside of the drain valve 12 beforehand. After the sewage inside the annular box 1 is purified, the drain valve 12 is opened to discharge the remaining sewage inside the filter cylinder 2. The above operation can be repeated for the next use.

[0043] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
