Description

Technical Field

[0001] This invention is a wastewater treatment device, belonging to the field of agricultural wastewater treatment technology. Background Technology

[0002] In the irrigation of high-standard farmland, water flows through irrigation canals to the edge of the fields. Influenced by agricultural wastewater, the water flowing in these canals contains a significant amount of organic pollutants, which can affect crops in the high-standard farmland. Micro-electrolysis technology, also known as internal electrolysis, is an ideal process for treating high-concentration organic wastewater. It utilizes the 1.2V potential difference generated by the micro-electrolysis materials packed in the wastewater to electrolyze the wastewater without applying electricity, thereby degrading organic pollutants. However, the water in the canals is constantly flowing. When the water flows into the container equipped with the micro-electrolysis packing for organic pollutant degradation, the contact time between the water and the packing is short, resulting in incomplete degradation of organic matter. Furthermore, the need for aeration around the packing necessitates additional aeration equipment, increasing equipment costs. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the object of the present invention is to provide a wastewater treatment device that, under the impact of water flow, generates bubbles around the micro-electrolysis packing material to achieve aeration, eliminating the need for additional aeration equipment and reducing equipment costs.

[0011] In a first aspect of the invention, as an optional embodiment, a plurality of heat dissipation holes are evenly provided on one side of the protective box, and a base plate strip is connected and fixed to the lower part of one side of the protective box.

[0012] In a first aspect of the invention, as an optional embodiment, a hollow cylinder for filtering aquatic plants and other debris is installed at the end of the water suction pipe away from the water pump, and a plurality of small holes are uniformly opened on the outer surface of the hollow cylinder.

[0013] In a first aspect of the invention, as an optional embodiment, a lifting rod is fixedly connected to each of the four corners at the bottom of the water tank, and the lower end of the lifting rod is fixedly connected to a chassis for burying in the ground.

[0014] In a first aspect of the invention, as an optional embodiment, the upper end of the lifting rod is fixed inside a ring, and the ring is connected and fixed to the water storage tank.

[0015] The present invention has the following beneficial effects:

[0016] 1. This invention utilizes a water pump to pump water from a ditch to a storage tank. When the timer valve is in operation, the water flowing into the storage tank is temporarily stored, increasing the contact time between the water and the micro-electrolysis system, thus facilitating the complete degradation of organic pollutants in the water. Simultaneously, when the water pump is working, water enters the closed-loop pipe through the channel formed by the outlet pipe and branch pipe. Subsequently, the water in the closed-loop pipe flows into the storage tank through the outlet hole. At this time, under the impact of the water flow, the air around the water surface forms bubbles that enter the water, causing bubbles to be generated around the micro-electrolysis packing material, achieving the purpose of aeration. No additional aeration equipment is required, reducing equipment costs. After the timer valve is opened, the water in the storage tank that has undergone degradation of organic pollutants flows into high-standard farmland, preventing organic pollutants from affecting crops in high-standard farmland.

[0017] 2. When the timer valve of this invention is in the closed state, as the water level in the storage tank increases, the float rises with the increase in water level. The float, via the vertical rod, drives the limiting head to slide upwards within the space formed by the limiting cylinder and the cylinder cover. This causes the limiting head to move the blocking rod upwards within the outlet pipe, sealing the connection between the branch pipe and the outlet pipe. Water entering the outlet pipe under the action of the pump then flows through the connecting pipe into the space formed by the end cover and the storage cylinder. As the water level in the storage cylinder increases, the piston moves away from the end cover within the storage cylinder and compresses the spring. The spring undergoes elastic deformation due to compression. During the piston's movement, the pressure plate moves along the guide hole, thereby pressing the contact of the limit switch, putting the limit switch in the open state and cutting off the pump. The circuit stops the water pump, allowing the pump's operation to be controlled based on the water level in the storage tank. This eliminates the need for manual control, reducing labor costs. After the timed valve opens, water is drained from the storage tank, causing the water level to drop. The float then descends until the stop rod no longer blocks the connection between the branch pipe and the outlet pipe. The spring's return force then causes the piston to move in the opposite direction, draining water from the storage tank. When the piston contacts the end cap, the pressure plate stops pressing the limit switch contacts, closing the limit switch and activating the pump's circuit, allowing it to continue operating. Because the stop rod has a certain length, after the water in the storage tank is drained, the stop rod moves to the underside of the connection between the branch pipe and the outlet pipe, while the pressure plate moves to a position where it no longer contacts the limit switch contacts.

[0018] 3. During the descent of the float in this invention, because the water in the storage tank is not completely drained, the blocking rod is still at the connection between the branch pipe and the outlet pipe. At this time, the force of the spring on the piston acts on the residual water in the outlet pipe. Since the water pump is in a stopped state, the impeller in the impeller chamber of the water pump does not rotate, so the water in the outlet pipe will not flow to the suction pipe. At this time, the residual water in the outlet pipe will exert a force on the blocking rod, forcing the float to move downward. The float drives the horizontal plate to move downward through the connecting rod. The horizontal plate drives the pressure rod to move the airbag head downward. The airbag head drives the micro-electrolysis packing to rotate in the support ring, changing the state of the micro-electrolysis packing so that different parts of the micro-electrolysis packing face upward, which is beneficial to the uniform utilization of the micro-electrolysis packing.

[0039] Example 1:

[0040] The water in the canal is in a flowing state. When the water in the canal flows into the container equipped with micro-electrolysis packing 7 to degrade organic pollutants, the contact time between the water and the micro-electrolysis packing 7 is short, and the degradation of organic matter is incomplete. At the same time, because aeration is carried out around the micro-electrolysis packing 7, aeration equipment needs to be added, which increases the equipment cost.

[0041] To resolve the above issues, please refer to [link / reference]. Figure 1 and Figure 14 The present invention provides a technical solution: a sewage treatment device, including a water channel 1, multiple water channels 1 connected end to end to form a water channel, a water storage tank 2 is provided on one side of the water channel 1, the upper end of the water storage tank 2 is open, and rings 41 are connected and fixed at the four corners of the bottom of the water storage tank 2. Lifting rods 3 are connected and fixed in the four rings 41, so that the upper end of the lifting rods 3 is fixed in the rings 41, thereby improving the mechanical strength of the connection between the lifting rods 3 and the water storage tank 2. The lower end of the lifting rods 3 is connected and fixed to a base plate 4 for burying in the ground, thereby preventing the water storage tank 2 from sinking by submerging the base plate 4 in the ground.

[0042] See Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 10 and Figure 11 A support plate 8 is installed on the upper surface of the water storage tank 2 near the water channel 1. A protective box 10 is installed on the upper surface of the support plate 8. A cover 9 is installed on the upper end of the protective box 10. A water pump 20 is installed inside the protective box 10. Multiple heat dissipation holes 35 are evenly opened on one side of the protective box 10. By processing the heat dissipation holes 35 on the protective box 10, the heat dissipation of the water pump 20 is facilitated. A base plate strip is connected and fixed to the lower part of one side of the protective box 10. The base plate strip is connected to the support plate 8 by multiple screws to complete the connection and fixation between the protective box 10 and the support plate 8. The water pump 20 and the limit switch 24 are installed in the space formed by the cover 9 and the protective box 10, which serves to protect the water pump 20 and the limit switch 24.

[0043] See Figure 1 , Figure 3 , Figure 4 and Figure 5 The water pump 20 is equipped with a suction pipe 11 at the inlet end. The other end of the suction pipe 11 passes through the protective box 10 and extends into the water channel 1. A hollow cylinder 19 for filtering aquatic plants and other debris is installed at the end of the suction pipe 11 away from the water pump 20. Multiple small holes 23 are evenly opened on the outer surface of the hollow cylinder 19. The hollow cylinder 19 with small holes 23 installed at one end of the suction pipe 11 serves to filter aquatic plants and other debris in the water and prevent aquatic plants and other debris from entering the water supply pipe.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 A water outlet pipe 16 is installed at the outlet end of the water pump 20. The end of the water outlet pipe 16 away from the water pump 20 extends to the outside of the protective box 10 and is arranged vertically. Two branch pipes 18 are installed on the outer surface of the vertical part of the water outlet pipe 16. A closed-loop pipe 6 is installed in the upper part of the water storage tank 2. The end of the branch pipe 18 away from the water outlet pipe 16 is connected to the closed-loop pipe 6. Multiple vertically arranged water outlet holes are evenly opened in the lower part of the outer surface of the closed-loop pipe 6. Multiple micro-electrolysis packing 7 are installed at equal intervals in the bottom of the water storage tank 2. Multiple timed switch valves 5 are installed on the side of the water storage tank 2 away from the water channel 1. The water pump 20 pumps water in the water channel 1 to the water storage tank 2. When the timed switch valve 5 is in the state, the water flowing into the water storage tank 2 will be temporarily stored. Inside water tank 2, the contact time between water and micro-electrolysis increases, which is beneficial for the complete degradation of organic pollutants in the water. At the same time, when water pump 20 is working, water enters the closed-loop pipe 6 through the channel formed by the outlet pipe 16 and the branch pipe 18. Then, the water in the closed-loop pipe 6 flows into the water storage tank 2 through the outlet hole. At this time, under the impact of the water flow, the air around the water surface will form bubbles and enter the water, causing bubbles to be generated around the micro-electrolysis packing 7, achieving the purpose of aeration. There is no need to add additional aeration equipment, reducing equipment costs. After the timed switch valve 5 is opened, the water in the water storage tank 2 that has undergone degradation of organic pollutants flows into the high-standard farmland, preventing organic pollutants from affecting the crops in the high-standard farmland.

[0045] Example 2:

[0046] Because the water storage tank 2 has a limited water storage capacity, the stopping and starting of the water pump 20 relies on manual control, that is, manually cutting off or connecting the circuit of the water pump 20. This method increases labor costs, and in the event of human negligence, the water that has not been completely degraded will overflow from the water storage tank 2 and flow into the high-standard farmland.

[0047] To resolve the above issues, please refer to 1. Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 The bottom of the outlet pipe 16 is provided with a limiting cylinder 14. The upper end of the limiting cylinder 14 is open. A cylinder cover 15 is connected and fixed to the upper end of the limiting cylinder 14. The cylinder cover 15 is sleeved on the outlet pipe 16 and connected and fixed to the outlet pipe 16. The cylinder cover 15 is located on the lower side of the branch pipe 18. A float ball 12 is provided directly below the limiting cylinder 14. A vertical rod 13 is connected and fixed to the upper part of the float ball 12. A through hole is opened in the middle of the bottom of the limiting cylinder 14. The upper end of the vertical rod 13 passes through the through hole and is connected and fixed to a limiting head 22. The limiting head 22 is slidably installed in the limiting cylinder 14. A blocking rod 21 for sealing the connection between the branch pipe 18 and the outlet pipe 16 is installed on the upper surface of the limiting head 22. The upper end of the blocking rod 21 extends to the upper side of the connection between the branch pipe 18 and the outlet pipe 16. Under the action of the limiting head 22, the vertical rod 13 is prevented from detaching from the limiting cylinder 14.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 10 A connecting pipe 17 is installed at the upper part of the vertical part of the water outlet pipe 16. The other end of the connecting pipe 17 passes through the protective box 10 and is connected to one end of the bend pipe 30. The end of the bend pipe 30 away from the connecting pipe 17 passes through the end cap 29 and is connected and fixed to the end cap 29. The end cap 29 is installed at the open end of the water storage cylinder 26. The water storage cylinder 26 is horizontally set in the upper part of the protective box 10. Multiple support rods 31 are fixed at the lower part of the outer surface of the water storage cylinder 26. The lower end of the support rods 31 is fixed to the bottom of the protective box 10. The support rods 31 play a role in restricting the position of the water storage cylinder 26. Under the action of the bend pipe 30, the water storage cylinder 26 is staggered from the water pump 20.

[0049] See Figures 1-10A piston 28 is slidably installed inside the water storage tank 26 to separate the internal space of the water storage tank 26. A pressure plate 33 is installed on the side of the piston 28 away from the end cover 29 to hold the contact part of the limit switch 24. A guide hole is opened on the side of the water storage tank 26 away from the end cover 29 to cooperate with the pressure plate 33. The end of the pressure plate 33 away from the piston 28 passes through the guide hole and extends to the outside of the water storage tank 26. The limit switch 24, which controls the on and off of the water pump 20 circuit, is located on the side of the pressure plate 33 on the outside of the water storage tank 26 away from the water storage tank 26. The limit switch 24 is connected and fixed to the cover 9 by screws. A spring 2 is provided on the side of the piston 28 away from the end cover 29. 7. Spring 27 is sleeved on pressure plate 33. When timer switch valve 5 is closed, as the water in water tank 2 increases, the liquid level in water tank 2 rises. At this time, float ball 12 rises with the liquid level. Float ball 12 drives limit head 22 to slide upwards in the space formed by limit cylinder 14 and cylinder cover 15 via vertical rod 13. Thus, limit head 22 drives blocking rod 21 to move upwards in outlet pipe 16, causing blocking rod 21 to seal the connection between branch pipe 18 and outlet pipe 16. At this time, water entering outlet pipe 16 under the action of water pump 20 flows into the space formed by end cover 29 and water tank 26 through connecting pipe 17. As water tank 26 rises, the water level in water tank 26 rises. As the water level inside the storage tank 26 increases, piston 28 moves away from end cap 29 within the storage tank 26, compressing spring 27. Spring 27 undergoes elastic deformation under compression. During this movement, piston 28 drives pressure plate 33 along the guide hole, which in turn compresses the contact portion of limit switch 24, causing it to open and disconnecting the circuit of water pump 20, thus stopping it from operating. This allows for control of water pump 20's operation based on the water level in storage tank 2, eliminating the need for manual control and reducing labor costs. When timer valve 5 opens, water is discharged from storage tank 2, causing the water level to drop. At this time, the float 12 descends. The piston moves in the opposite direction under the action of the spring 27, causing the piston 28 to move and the water to be discharged from the water storage tank 26. When the piston 28 moves to contact the end cover 29, the pressure plate 33 stops pressing the contact of the limit switch 24, and the limit switch 24 is closed, thereby connecting the circuit of the water pump 20 and allowing the water pump 20 to continue to work. Because the plug rod 21 has a certain length, after the water in the water storage tank 2 is discharged, the plug rod 21 moves to the lower side of the connection between the branch pipe 18 and the water outlet pipe 16, and at the same time the pressure plate 33 moves to a position where it does not contact the contact of the limit switch 24.

[0050] See Figure 10An arc-shaped head 34 is fixedly connected to the end of the pressure plate 33 away from the piston 28. The arc-shaped head 34 and the pressure plate 33 are integrally formed. Under the action of the arc-shaped head 34, the pressure plate 33 makes smooth contact with the contact part of the limit switch 24. A support plate 32 is fixedly connected to the end of the pressure plate 33 near the piston 28. The support plate 32 is fixedly connected to the piston 28. Under the action of the support plate 32, the strength of the piston 28 structure is improved. Multiple blocking rods 25 are evenly fixed on the inner wall of the water storage cylinder 26 facing the support plate 32 to limit the movement range of the piston 28. The blocking rods 25 are arranged along the length of the water storage cylinder 26. When the support plate 32 contacts the blocking rod 25, under the limitation of the blocking rod 25, the piston 28 no longer moves away from the end cover 29, thereby avoiding the spring 27 being over-compressed and damaged, and playing the role of protecting the spring 27.

[0051] Example 3:

[0052] After the micro-electrolysis packing 7 is installed at the bottom of the water storage tank 2, the state of the micro-electrolysis packing 7 cannot be adjusted. Therefore, the downward part of the micro-electrolysis packing 7 cannot come into contact with the air bubbles generated by the water flow impact, resulting in poor aeration effect and low utilization rate of the micro-electrolysis packing 7.

[0053] To resolve the above issues, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 12 and Figure 13A float 12 is positioned on the upper side of the micro-electrolysis packing 7. A connecting rod 37 is installed on the lower part of the outer surface of the float 12. The lower end of the connecting rod 37 is connected and fixed to the horizontal plate 38. The connecting rod 37 connects the horizontal plate 38 and the float 12, allowing the horizontal plate 38 to rise and fall with the float 12. The horizontal plate 38 is arranged perpendicularly to the micro-electrolysis packing 7, which has a circular cross-section. Both ends of the micro-electrolysis packing 7 are provided with support rings 36, which slide in contact with the micro-electrolysis packing 7 and are fixed to the inner wall of the water storage tank 2 by screws. Multiple pressure rods 39 are evenly fixed on the lower surface of the horizontal plate 38. An air bladder head 40 is installed at the lower end of the pressure rod 39, which is obliquely above and in contact with the micro-electrolysis packing 7. During the descent of the float 12, because the water in the water storage tank 2 is not completely drained, the blockage occurs. When rod 21 is still in the part where the branch pipe 18 is connected to the outlet pipe 16, the force of spring 27 on piston 28 acts on the water remaining in outlet pipe 16. Since the water pump 20 is in a stopped state, the impeller in the impeller chamber of the water pump 20 does not rotate, so the water in outlet pipe 16 will not flow to suction pipe 11. At this time, the water remaining in outlet pipe 16 will exert force on the blocking rod 21, forcing float 12 to move downward. Float 12 drives horizontal plate 38 to move downward through connecting rod 37. Horizontal plate 38 drives pressure rod 39 to drive airbag head 40 to move downward. Airbag head 40 drives micro-electrolysis packing 7 to rotate in support ring 36, changing the state of micro-electrolysis packing 7 so that different parts of micro-electrolysis packing 7 face upward, which is beneficial for the uniform utilization of micro-electrolysis packing 7.
