Description

Technical Field

[0001] The utility model relates to the technical field of precipitation devices, in particular to a precipitation device for processing a high-efficiency dephosphorization agent. Background Art

[0002] Phosphorus removal from sewage is a commonly used sewage treatment method. Phosphorus is one of the main nutrients that cause eutrophication of water bodies. Excessive phosphorus will cause algae to reproduce in large numbers, leading to deterioration of water quality. Common phosphorus removal processes include chemical precipitation, biological phosphorus removal, physical coagulation and sedimentation, etc. Among them, chemical precipitation is to add flocculants to sewage to quickly separate water and mud. Compared with other methods, chemical precipitation does not require a lot of energy consumption or the addition of additional chemical agents, so it can reduce the operating cost of the phosphorus removal process. Chemical precipitation can effectively remove phosphorus in water in the form of solid sediment, thereby reducing the phosphorus content in the water to the discharge standard of 1.0 mg / L, which helps to improve water quality, reduce eutrophication problems, and protect the water environment. Chemical precipitation has simple operating procedures and maintenance requirements, and operators can easily monitor and manage it. It is easy to operate and has good reliability and stability.

[0003] However, the existing sedimentation equipment for phosphorus removal processing often mixes some fine mud into the clear water precipitated during sewage treatment, and cannot effectively separate the mud from the water. After the flocculant is added to the sewage, the flocculant often cannot fully mix with the water to react, and the flocculant cannot be effectively utilized. Due to the slow sedimentation rate, the efficiency of sewage treatment is affected.

[0004] Therefore, a precipitation device for processing high-efficiency phosphorus removal agent is proposed. Utility Model Content

[0005] The main purpose of the utility model is to provide a sedimentation device for processing high-efficiency phosphorus removal agents, which can effectively solve the problems of inability to effectively separate mud and water during the sedimentation process, low sewage treatment efficiency caused by slow mud sedimentation speed, and inability of added flocculants to be fully mixed with sewage.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a sedimentation device for processing high-efficiency phosphorus removal agent, including a sedimentation box, a plurality of inclined baffles are fixedly installed on the upper end of the sedimentation box, a clean water tank is fixedly installed on one side of the top of the sedimentation box, a clean water pipe is connected to one side of the clean water tank, a first fixed frame is fixedly installed on the lower end of the sedimentation box, and a sludge pipe is connected to the center of the lower end of the sedimentation box.

[0007] Preferably, a first motor is fixedly installed at the lower end of the sludge pipe, a first shaft is fixedly installed at the output end of the first motor passing through the sludge pipe, and the other end of the first shaft is located in the sedimentation box, a first support rod is fixedly installed at one end of the first shaft, and four scrapers are fixedly installed on the first support rod.

[0009] Preferably, one end of the first connecting pipe is connected to a mixing pool, one side of the mixing pool is connected to a sewage pipe, a third motor is fixedly installed on one side of the mixing pool, the output end of the third motor passes through the mixing pool and is fixedly installed with a third shaft rod, six second support rods are fixedly installed on the third shaft rod, and one end of the six second support rods is fixedly installed with a stirring blade.

[0010] Preferably, support plates are fixedly installed on both sides of the upper end of the mixing tank, and drug delivery tubes are fixedly sleeved on the upper ends of the two support plates. One end of the drug delivery tube passes through one of the support plates, and the lower end of the surface of the drug delivery tube is connected to two dosing nozzles.

[0011] Preferably, a second fixing bracket is fixedly installed at the lower end of the mixing tank, a control panel is fixedly installed on one side of the second fixing bracket, and the control panel is electrically connected to the first motor, the second motor, and the third motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The utility model has an inclined baffle, which can effectively increase the water flow path when water flows through, prolong the time that sewage stays in the pool, and give the sludge more opportunities to settle to the bottom of the pool, thereby effectively separating water and mud. Under the same water volume, the sedimentation time is reduced by 40%-55% compared with ordinary sedimentation devices.

[0014] 2. The utility model can effectively mix the added flocculant through the stirring blades provided. By controlling the output end of the third motor to rotate the third shaft, the stirring blades at one end of the six second support rods on the third shaft can be driven to rotate, so that the sewage and the flocculant are fully stirred and reacted, thereby effectively mixing the flocculant and the sewage. The phosphorus content in the water body can be reduced to 1.0 mg / L, and the required amount of flocculant can be effectively reduced by 15%-20% compared with the existing equipment.

[0015] 3. The utility model can effectively solve the problem of low sewage treatment efficiency by setting up a flocculation box. By controlling the output end of the second motor to slowly rotate the stirring rod on the second shaft, the stirring rod stirs the sewage to form a vortex in the flocculation box.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-2As shown, a sedimentation device for processing a high-efficiency dephosphorus agent includes a sedimentation box 1, wherein a plurality of inclined baffles 2 are fixedly installed on the upper end of the sedimentation box 1, a clean water tank 3 is fixedly installed on one side of the top of the sedimentation box 1, and a clean water pipe 4 is connected to one side of the clean water tank 3, a first fixed frame 5 is fixedly installed on the lower end of the sedimentation box 1, and a sludge pipe 6 is connected to the center of the lower end of the sedimentation box 1. By adopting the above technical solution, the inclined baffles 2 can block the sludge below and flow the clean water into the upper clean water tank 3. The sludge pipe 6 below can transport the collected sludge to a subsequent process. The plurality of inclined baffles 2 can form a plurality of water flow channels at the upper end of the sedimentation box 1. When the water flows through, the water will pass through the water flow channels formed between the plurality of inclined baffles 2, which can effectively increase the water flow path, prolong the time that the sewage stays in the pool, and give the sludge more opportunities to settle to the bottom of the pool, thereby effectively separating the water and the mud. Under the same water volume, the sedimentation time is reduced by 40%-55% compared with the ordinary sedimentation device.

[0026] like Figure 2-Figure 3 As shown, a first motor 7 is fixedly installed at the lower end of the sludge pipe 6, and a first shaft rod 8 is fixedly installed at the output end of the first motor 7 passing through the sludge pipe 6, and the other end of the first shaft rod 8 is located in the sedimentation tank 1, and a first support rod 9 is fixedly installed at one end of the first shaft rod 8, and four scrapers 10 are fixedly installed on the first support rod 9. By adopting the above technical solution, the output end of the first motor 7 is controlled to rotate the first shaft rod 8, so that the first shaft rod 8 drives the scraper 10 on the first support rod 9, so that the scraper 10 can collect the sludge at the bottom of the sedimentation tank 1 into the sludge pipe 6.

[0027] like Figure 1-4 As shown, one side of the sedimentation tank 1 is connected to a second connecting pipe 11, the upper end of the second connecting pipe 11 is connected to a flocculation tank 12, the upper end of the flocculation tank 12 is fixedly installed with a second motor 13, the output shaft of the second motor 13 passes through the flocculation tank 12 and is fixedly installed with a second shaft 14, three stirring rods 15 are fixedly installed on the second shaft 14, and one side of the upper end of the flocculation tank 12 is connected to a first connecting pipe 16. By adopting the above technical solution, the output end of the second motor 13 is controlled to slowly rotate the stirring rod 15 on the second shaft 14, so that the stirring rod 15 stirs the sewage to form a vortex in the flocculation tank 12, so that the sewage mixed with the flocculant forms larger flocs, which are then precipitated more quickly.

[0028] like Figure 1-6As shown, one end of the first connecting pipe 16 is connected to the mixing tank 17, and one side of the mixing tank is connected to the sewage pipe 25. A third motor 18 is fixedly installed on one side of the mixing tank 17, and the output end of the third motor 18 passes through the mixing tank 17 and is fixedly installed with a third shaft 19. Six second support rods 20 are fixedly installed on the third shaft 19, and one end of the six second support rods 20 is fixedly installed with stirring blades 21. By adopting the above technical solution, the output end of the third motor 18 is controlled to rotate the third shaft 19, which can drive the stirring blades 21 at one end of the six second support rods 20 on the third shaft 19 to rotate, so that the sewage and flocculant are fully stirred and reacted, thereby effectively mixing the flocculant with the sewage, and the phosphorus content in the water body can be reduced to 1.0 mg / L. The required amount of flocculant can be effectively reduced by 15%-20% compared with the existing equipment.

[0029] like Figure 5-6 As shown, support plates 22 are fixedly installed on both sides of the upper end of the mixing tank 17, and a drug delivery tube 23 is fixedly sleeved on the upper ends of the two support plates 22. One end of the drug delivery tube 23 passes through one of the support plates 22, and the lower end of the surface of the drug delivery tube 23 is connected to two drug dosing nozzles 24. By adopting the above technical solution, the drug delivery tube 23 passes through one end of the support plate 22 and can be connected to an external drug supply system. The drug dosing nozzle 24 connected to the drug delivery tube 23 can spray the flocculant into the mixing tank 17 below.

[0030] like Figure 1 As shown, a second fixing frame 26 is fixedly installed at the lower end of the mixing tank 17, and a control panel 27 is fixedly installed on one side of the second fixing frame 26. The control panel 27 is electrically connected to the first motor 7, the second motor 13, and the third motor 18. By adopting the above technical solution, the second fixing frame 26 can fix the mixing tank 17 on the second fixing frame 26, and the control panel 27 can control the start and stop of the first motor 7, the second motor 13, and the third motor 18.

[0031] It should be noted that the present invention is a sedimentation device for processing high-efficiency dephosphorization agents. When in use, first install the first fixing frame 5 and the second fixing frame 26 in appropriate positions, and the sewage flows into the mixing tank 17 from the sewage pipe 25. The flocculant is delivered to the drug delivery pipe 23 through the drug supply system, and the flocculant is delivered to the dosing nozzle 24 through the drug delivery pipe 23 and sprayed into the mixing tank 17. The third motor 18 is started through the control panel 27, and the third motor 18 drives the third shaft 19 to rotate, so that the second support rod 20 and the stirring blade 21 on the third shaft 19 rotate, and the flocculant sprayed into the mixing tank 17 by the dosing nozzle 24 is fully mixed with the sewage. The mixed sewage will flow into the flocculation box 12 through the first connecting pipe 16. Next, start the second motor 13, so that the second shaft 14 connected to the output end of the second motor 13 drives the stirring rod 15 to rotate slowly, so that the stirring rod 15 stirs the sewage to form a vortex in the flocculation box 12 , so that the sewage mixed with flocculant forms larger flocs. After the flocs are formed, the sewage will flow into the sedimentation tank 1 along the second connecting pipe 11. After the sewage enters the sedimentation tank 1, the flocculated sludge will sink due to gravity, and some sludge with smaller flocculation will still float up. The floating sludge will pass through the inclined baffle 2 installed on the sedimentation tank 1. Since the inclined baffle 2 increases the water flow path, the residence time of the sewage in the pool is prolonged, and the sedimentation speed of the sludge is increased, so that the sludge has more opportunities to settle to the bottom of the pool. The clean water flowing above will overflow into the clean water tank 3 and be transported to the clean water pipe 4 installed on the clean water tank for subsequent purification treatment. The precipitated sludge will accumulate at the bottom of the sedimentation tank 1. By controlling the output end of the first motor 7 to rotate the first shaft 8, the first shaft 8 drives the scraper 10 on the support rod 9, so that the scraper 10 can collect the sludge at the bottom of the sedimentation tank 1 into the sludge pipe 6. The sludge collected in the sludge pipe 6 can be transported for subsequent treatment.
