Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-oxygen sludge thickening device. Background Technology

[0002] In practice, sludge treatment methods include natural drying, mechanical dewatering, landfilling after drying, and incineration. Among these, mechanical dewatering is a commonly used method, which can separate the water from the sludge mechanically, making the sludge easier to transport and store. In addition, some new sludge treatment methods are constantly emerging, such as thermochemical treatment and biological treatment. These methods help improve the efficiency and quality of sludge treatment.

[0003] When existing sludge thickening devices are in use, if the wastewater remains for a long time and causes oxygen deficiency, denitrifying bacteria will convert nitrates into ammonia and nitrogen. When ammonia and nitrogen escape, the sludge will adsorb ammonia and nitrogen and float to the surface, which will reduce the settling properties of the sludge.

[0004] Therefore, to address the problem that existing sludge thickening devices, when wastewater remains for extended periods, leading to oxygen deficiency, cause denitrifying bacteria to convert nitrates into ammonia and nitrogen. As the ammonia and nitrogen escape, the sludge absorbs them and floats to the surface, reducing its settling properties. A high-oxygen sludge thickening device can be designed. This device involves setting up a reaction chamber, opening its inlet, and adding oxidants and other chemical raw materials. The reaction inside the chamber produces high-purity oxygen. An air pump is then activated to transport the oxygen from the reaction chamber through a hose to a conduit, which is then injected into the sludge tank. This initiates an oxidation reaction, destroying organic matter and harmful microorganisms in the sludge. This prevents bacteria from forming extracellular polysaccharide polymers due to anaerobic conditions, which would negatively impact cell wall breaking and dewatering, while simultaneously improving sludge thickening efficiency. Utility Model Content

[0005] To overcome the problem that existing sludge thickening devices cause oxygen deficiency due to prolonged wastewater retention, denitrifying bacteria convert nitrates into ammonia and nitrogen, and when ammonia and nitrogen escape, the sludge absorbs ammonia and nitrogen and floats to the surface, thus reducing the settling properties of the sludge.

[0006] The technical solution of this utility model is as follows: a high-oxygen sludge thickening device, including a sludge tank; it also includes a reaction chamber, a sealing cover, an inlet, an air pump, a hose, a movable seat, and a conduit.

[0007] Preferably, by setting up a reaction chamber, opening the addition port of the reaction chamber, and adding chemical raw materials such as oxidants into the reaction chamber, a reaction occurs inside the reaction chamber to produce high-purity oxygen. Then, the air pump is turned on to transport the oxygen inside the reaction chamber through a hose to the inside of the conduit, and injects it into the sludge tank from the port of the conduit. This initiates an oxidation reaction, destroying organic matter and harmful microorganisms in the sludge. This prevents bacteria in the sludge from forming extracellular polysaccharide polymers due to anaerobic conditions, which would affect the cell wall breaking and dewatering effect. At the same time, it improves the sludge thickening efficiency. This solves the problem in existing sludge thickening devices where, when wastewater stays for a long time and causes oxygen deficiency, denitrifying bacteria convert nitrates into ammonia and nitrogen.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a reaction chamber, opening the inlet of the reaction chamber, and adding chemical raw materials such as oxidants into the chamber, a reaction occurs inside the chamber to produce high-purity oxygen. Then, the air pump is turned on to transport the oxygen from the reaction chamber to the inside of the conduit through a hose, and injects it into the sludge tank from the conduit port. This initiates an oxidation reaction, destroying organic matter and harmful microorganisms in the sludge. This prevents bacteria in the sludge from forming extracellular polysaccharide polymers due to anaerobic conditions, which would affect the cell wall breaking and dewatering effect. At the same time, it improves the sludge thickening efficiency. This solves the problem in existing sludge thickening devices where, during prolonged wastewater retention and oxygen deficiency, denitrifying bacteria convert nitrates into ammonia and nitrogen. When ammonia and nitrogen escape, the sludge adsorbs the ammonia and nitrogen and floats to the surface, reducing the sludge settling properties. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a high-oxygen sludge thickening device, including a sludge tank 1; it also includes a reaction chamber 2, a sealing cover 3, an inlet 4, an air pump 5, a hose 6, a movable seat 7, and a conduit 8. The reaction chamber 2 is located at the left end of the rear surface of the sludge tank 1. The sealing cover 3 is located on the top surface of the reaction chamber 2. The inlet 4 is located on the left side of the upper surface of the sealing cover 3. The air pump 5 is located in the middle of the upper surface of the sealing cover 3. One end of the hose 6 is located at the air outlet end of the top surface of the air pump 5. The other end of the hose 6 is connected to the movable seat 7. The bottom surface of the movable seat 7 is forward. A conduit 8 is installed at the location. By setting up a reaction chamber 2, opening the addition port 4 of the reaction chamber 2, and adding chemical raw materials such as oxidants into the reaction chamber 2, a reaction takes place inside the reaction chamber 2 to produce high-purity oxygen. Then, the air pump 5 is turned on to transport the oxygen inside the reaction chamber 2 to the inside of the conduit 8 through the hose 6, and inject it into the inside of the sludge tank 1 from the port of the conduit 8. This initiates an oxidation reaction, destroys organic matter and harmful microorganisms in the sludge, and prevents bacteria in the sludge from forming extracellular polysaccharide polymers due to anaerobic conditions, which would affect the cell wall breaking and dewatering effect. At the same time, it improves the sludge concentration efficiency.

[0023] Please see Figures 1-3 In this embodiment, electric guide rails 9 are provided on the left side of the front and rear sides of the inner surface of the sludge tank 1. An electric slider 10 is slidably connected to the upper surface of the electric guide rails 9. A frame 11 is provided on the upper surface of the electric slider 10. By setting the electric guide rails 9 and the electric slider 10, after opening, the electric slider 10 can move back and forth above the sludge tank with the frame 11, thereby causing the moving seat 7 to drive the bottom guide tube 8 to move synchronously. A drive motor 12 is installed on the left side surface of the frame 11. The output end of the drive motor 12 passes through the left side surface of the frame 11 and is connected to one end of a screw 13. The screw 13 is threadedly connected to the moving seat 7. The other end of the screw 13 is rotatably connected to the right side of the inner surface of the frame 11. By setting the drive motor 12, its output during operation... The output end drives the screw 13 to rotate, and the screw 13 drives the moving seat 7, which is threaded to it, to reciprocate left and right, thereby driving the guide tube 8 to move left and right. With the cooperation of the electric slider 10, it can achieve all-round coverage of the sludge tank 1 and improve the coverage range of high-purity oxygen. Limiting rods 14 are set on the right side of the front and rear sides of the inner surface of the sludge tank 1. The outer surface of the limiting rod 14 is slidably connected to the limiting seat 15. The upper surface of the limiting seat 15 is connected to the right side of the bottom surface of the frame 11. By setting the limiting rod 14 and the limiting seat 15, when the frame 11 moves back and forth, it will drive the limiting seat 15 to slide on the outer surface of the limiting rod 14. The limiting rod 14 plays the role of limiting the direction of movement, thereby improving the stability and accuracy of the device operation.

[0024] Please see Figures 1-4In this embodiment, symmetrical limiting grooves 16 are provided on the front and rear sides of the inner surface of the frame 11. Limiting blocks 17 are installed on the front and rear sides of the movable seat 7. The limiting blocks 17 match the limiting grooves 16. By setting the limiting grooves 16 and the limiting blocks 17, when the movable seat 7 moves left and right, the limiting blocks 17 will move synchronously inside the limiting grooves 16. When the screw 13 rotates, the movable seat 7 is restricted by the limiting blocks 17 and will not rotate, thereby ensuring that the movable seat 7 can move left and right normally and improving the transmission efficiency. A servo motor 18 is provided on the bottom surface of the reaction tank 2. A transmission shaft 19 is provided through the bottom surface of the servo motor 18. Four circumferentially distributed stirring rods 20 are provided on the outer surface of the transmission shaft 19. By setting the servo motor 18, its output end will drive the transmission shaft 19 to rotate during operation. The transmission shaft 19 will then drive the stirring rods 20 to rotate synchronously. To improve the mixing efficiency and flow rate of the solution inside reaction chamber 2, thereby increasing the oxygen production rate, a pressure sensor 21 is installed on the right side of the upper surface of the sealing cover 3. A temperature sensor 22 is installed on the upper surface of the sealing cover 3 behind the pressure sensor 21. A controller 23 is installed on the right side of the outer surface of reaction chamber 2, and a display screen 24 is installed on the front right side of the sludge tank 1. The controller 23 is electrically connected to the pressure sensor 21, the temperature sensor 22, and the display screen 24. The pressure sensor 21 (model CYYZ11) can monitor the pressure inside reaction chamber 2 in real time, and the temperature sensor 22 (model CWDZ11) can monitor the temperature inside reaction chamber 2. The detection data from both sensors are transmitted to the display screen 24 through the controller 23 for easy observation of temperature and pressure changes inside reaction chamber 2 by the staff.

[0025] During operation, an electric guide rail 9 and an electric slider 10 are installed. Once activated, the electric slider 10 moves the frame 11 back and forth above the sewage tank, causing the moving seat 7 to move synchronously with the bottom conduit 8. A drive motor 12 drives a screw 13 to rotate during operation. The screw 13 drives the threaded moving seat 7 to reciprocate left and right, thus moving the conduit 8 left and right. In conjunction with the electric slider 10, this achieves comprehensive coverage of the sludge tank 1, increasing the coverage area of ​​high-purity oxygen. A limiting rod 14 and a limiting seat 15 are installed. When the frame 11 moves back and forth, the limiting seat 15 slides on the outer surface of the limiting rod 14. The limiting rod 14 restricts the direction of movement, improving the stability and accuracy of the device. A limiting groove 16 and a limiting block 17 are installed to allow the moving seat 7 to move left and right. When the screw 13 rotates, the limiting block 17 moves synchronously inside the limiting groove 16. When the screw 13 rotates, the moving seat 7 is restricted by the limiting block 17 and will not rotate, thus ensuring that the moving seat 7 can move normally left and right, improving transmission efficiency. By setting a servo motor 18, its output end will drive the transmission shaft 19 to rotate during operation. The transmission shaft 19 will drive the stirring rod 20 to rotate synchronously, thereby improving the mixing efficiency and flow rate of the solution inside the reaction chamber 2, thereby increasing the rate of oxygen production. By setting a pressure sensor 21, model CYYZ11, the pressure inside the reaction chamber 2 can be monitored in real time. By setting a temperature sensor 22, model CWDZ11, the temperature inside the reaction chamber 2 can be monitored. The detection data of the two sensors are transmitted to the display screen 24 through the controller 23 for display, so that the staff can intuitively observe the temperature and pressure changes inside the reaction chamber 2.

[0026] Through the above steps, by setting up reaction tank 2, opening the addition port 4 of reaction tank 2, and adding chemical raw materials such as oxidant into the interior of reaction tank 2, a reaction occurs inside reaction tank 2, producing high-purity oxygen. Then, the air pump 5 is turned on to transport the oxygen inside reaction tank 2 through hose 6 to the inside of conduit 8, and injects it into the interior of sludge tank 1 from the port of conduit 8. This triggers an oxidation reaction, destroying organic matter and harmful microorganisms in the sludge, preventing bacteria in the sludge from forming extracellular polysaccharide polymers due to anaerobic conditions, which would affect the cell wall breaking and dewatering effect. At the same time, it improves the sludge thickening efficiency. This solves the problem that when existing sludge thickening devices are used, if sewage stays for a long time and causes oxygen deficiency, denitrifying bacteria will convert nitrates into ammonia and nitrogen. When ammonia and nitrogen escape, the sludge adsorbs ammonia and nitrogen and floats up, reducing the settling properties of the sludge.
