Description

Technical Field

[0001] This utility model relates to the field of stearate wastewater, and specifically to a stearate wastewater treatment device. Background Technology

[0002] Stearate wastewater refers to wastewater containing stearates such as calcium stearate, magnesium stearate, and zinc stearate discharged during industrial production processes. Stearates are salts formed by the reaction of stearic acid, a long-chain fatty acid, with metal ions such as calcium, magnesium, zinc, and aluminum. Stearate wastewater treatment equipment is a treatment system specifically designed for the characteristics of stearate wastewater. It removes stearates and other pollutants from the wastewater through multi-stage processes including physical, chemical, and biological methods, ensuring that the effluent meets discharge standards or can be reused.

[0003] Existing stearate wastewater treatment devices lack the ability to continuously remove fouling and chemically coagulate during the pretreatment stage. They simply filter the stearate wastewater during the pretreatment stage, which leads to a longer treatment cycle and makes it unable to handle high-concentration or fluctuating wastewater. Moreover, relying solely on the single pretreatment method of filtration followed by sedimentation makes it difficult to simultaneously and efficiently remove oil, suspended solids, and dissolved pollutants, and also results in unstable effluent quality from the stearate wastewater treatment device.

[0004] Therefore, it is necessary to invent a stearate wastewater treatment device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a stearate wastewater treatment device. Through a pretreatment tank, a first telescopic cylinder, a lifting frame, a spacer filter, a push plate scraper, a spacer cylinder, a fixing frame, and a mixing rod, this device enables continuous fouling removal and chemical coagulation during the pretreatment stage. This design, through the synergistic effect of physical separation and chemical coagulation, avoids the downtime and cleaning time of traditional intermittent treatment, significantly improving treatment efficiency. Furthermore, physical separation can quickly remove large particles, while chemical coagulation targets dissolved or finely suspended stearates, providing dual protection against pipe blockage and biochemical treatment system failure. This addresses the problem in existing stearate wastewater treatment devices that lack continuous fouling removal and chemical coagulation capabilities during the pretreatment stage, relying solely on filtration. This leads to prolonged treatment cycles, inability to handle high-concentration or fluctuating wastewater, and the inability to simultaneously and efficiently remove oil, suspended solids, and dissolved pollutants through filtration followed by sedimentation, resulting in unstable effluent quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stearate wastewater treatment device, including a treatment base for supporting the main body for stearate wastewater treatment;

[0007] A pretreatment tank is fixedly installed above the treatment base for pretreatment of stearate wastewater. An inlet pipe is fixedly installed on the outside of the pretreatment tank. A first telescopic cylinder is fixedly installed on the outside of the pretreatment tank. A lifting frame is fixedly installed on the top of the first telescopic cylinder. A spacer filter is fixedly installed on the bottom of the lifting frame.

[0008] The sludge outlet is located inside the pretreatment tank for the discharge of oil and sludge. A second telescopic cylinder is fixedly installed on the outside of the pretreatment tank, and a push plate scraper is fixedly installed at the front end of the second telescopic cylinder. A spacer is fixedly installed on the top of the lifting frame, a spacing cylinder is fixedly installed above the spacer, a fixing frame is fixedly installed at the bottom of the spacing cylinder, a servo motor is fixedly installed above the fixing frame, and a mixing rod is fixedly installed at the output end of the servo motor.

[0009] A spray filter chamber is fixedly installed above the treatment base for filtering pretreated wastewater. A pressurized water pump is fixedly installed on the top of the spray filter chamber. A water pumping pipe is fixedly installed on one end of the pressurized water pump, and a water delivery pipe is fixedly installed on the other end of the pressurized water pump.

[0010] Preferably, the spacer filter is slidably connected to the pretreatment tank, and the lifting frame is symmetrically arranged about the central axis of the spacer filter.

[0011] Preferably, the mixing rod is rotatably connected to the pretreatment tank, and the spacer is configured with an L-shaped structure.

[0012] Preferably, the other end of the pumping pipe is fixedly connected to the outside of the pretreatment tank, and the other end of the water supply pipe is fixedly connected to a spray chamber.

[0013] Preferably, each of the spray filter chambers is fixedly equipped with a spray pipe, and each of the spray pipes is fixedly equipped with a spray head at its bottom.

[0014] Preferably, a packing frame is threadedly connected inside the spray filter chamber, an activated carbon filter screen is threadedly connected to the bottom of the spray filter chamber, a return box is fixedly installed inside the spray filter chamber, and an outlet pipe is fixedly installed outside the return box.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This utility model includes a pretreatment tank, a first telescopic cylinder, a lifting frame, a spacer filter, a pusher scraper, a spacing cylinder, a fixing frame, and a mixing rod. When using this stearate wastewater treatment device, the first telescopic cylinder first moves the spacer filter to the middle of the pretreatment tank. Then, the wastewater dirt and oil entering the pretreatment tank are separated into the upper space by the spacer filter. The spacer filter then rises at a constant speed via the first telescopic cylinder, and the pusher scraper pushes the dirt and oil out of the dirt inlet into the external dirt tank. Next, a measured amount of flocculant can be added to the pretreatment tank, and the mixture is then stirred by the spacing cylinder. The mixing rod is lowered to complete the mixing. The dirt solidified by the flocculant can also be pushed out of the dirt outlet by the push plate scraper in the same way. This combination allows the stearate wastewater treatment device to have the ability to continuously remove dirt and chemically coagulate in the pretreatment stage. This design avoids the downtime for cleaning of traditional intermittent treatment through the synergistic effect of physical separation and chemical coagulation, which significantly improves the treatment efficiency. Moreover, physical separation can quickly remove large particles, while chemical coagulation is aimed at soluble or small suspended stearates. This dual protection avoids pipe blockage and failure of the biological treatment system. Attached Figure Description

The top of the first telescopic cylinder 4 is fixedly installed with a lifting frame 5 and the bottom of the lifting frame 5 is fixedly installed with a spacer filter screen 6.

[0028] The dirt outlet 7 is located inside the pretreatment tank 2 and is used for the discharge of oil and dirt. The exterior of the pretreatment tank 2 is fixedly equipped with a second telescopic cylinder 8. The front end of the second telescopic cylinder 8 is fixedly equipped with a push plate scraper 9. The top of the lifting frame 5 is fixedly equipped with a spacer frame 10. The spacer frame 10 is fixedly equipped with a spacing cylinder 11 above the spacer frame 10. The bottom end of the spacing cylinder 11 is fixedly equipped with a fixing frame 12. The fixing frame 12 is fixedly equipped with a servo motor 13 above the fixing frame 12. The output end of the servo motor 13 is fixedly equipped with a mixing rod 14.

[0029] The spray filter chamber 15 is fixedly installed above the treatment base 1 and is used to filter the pretreated wastewater. A pressurized water pump 16 is fixedly installed on the top of the spray filter chamber 15. A water pumping pipe 17 is fixedly installed on one end of the pressurized water pump 16 and a water delivery pipe 18 is fixedly installed on the other end of the pressurized water pump 16. The wastewater treated by the pretreatment tank 2 can be directly pumped out from the bottom of the pretreatment tank 2 through the pressurized water pump 16 and then fed into the spray filter chamber 15, thereby completing the stearate wastewater treatment process.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the spacer filter 6 is slidably connected to the pretreatment tank 2, and the lifting frame 5 is symmetrically arranged with respect to the central axis of the spacer filter 6. The first telescopic cylinder 4 can drive the spacer filter 6 to slide to the middle position of the pretreatment tank 2. Then, the wastewater dirt and oil entering the pretreatment tank 2 are separated into the upper space by the spacer filter 6. The mixing and stirring rod 14 is rotatably connected to the pretreatment tank 2. The spacer frame 10 is set with an L-shaped structure, which can add a certain amount of flocculant to the pretreatment tank 2. The mixing and stirring rod 14 is lowered by the spacer cylinder 11 to complete the mixing.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the other end of the pumping pipe 17 is fixedly connected to the outside of the pretreatment tank 2, and the other end of the water supply pipe 18 is fixedly connected to the spray chamber 19. The overall structure of the pumping pipe 17 is simple and easy to operate, and it is convenient for maintenance personnel to repair in time if a fault occurs. Spray pipes 20 are fixedly installed inside the spray filter chamber 15, and spray heads 21 are fixedly installed at the bottom of the spray pipes 20. The spray pipes 20 and spray heads 21 spray the pretreated wastewater evenly, making the process of treating stearate wastewater more detailed. The inside of the spray filter chamber 15 is threadedly connected to the packing frame 22, and the bottom of the spray filter chamber 15 is threadedly connected to the activated carbon filter screen 23. The inside of the spray filter chamber 15 is fixedly installed to the return box 24, and the outside of the return box 24 is fixedly installed to the outlet pipe 25. The inside of the packing frame 22 is filled with quartz sand, allowing the wastewater to penetrate layer by layer. Combined with the filtration of the activated carbon filter screen 23, the stearate wastewater is treated to meet the discharge or recycling requirements.

[0032] The working principle of this utility model is as follows: First, connect the external power supply and connect the inlet pipe 3 to the stearate wastewater discharge pipe. Then, turn on the switch of the first telescopic cylinder 4, causing the first telescopic cylinder 4 to move the spacer filter 6 to the middle position of the pretreatment tank 2. In this way, the wastewater dirt and oil entering the pretreatment tank 2 are separated into the upper space by the spacer filter 6. Next, the first telescopic cylinder 4 raises the spacer filter 6 at a constant speed, allowing the spacer filter 6 to carry the dirt and oil to the level of the dirt inlet 7. Then, turn on the switch of the second telescopic cylinder 8, causing the second telescopic cylinder 8 to move the push plate scraper 9 back and forth on the spacer filter 6. In this way, the push plate scraper 9 removes the dirt and oil from the spacer filter 6. Dirt and oil are pushed out of the dirt inlet 7 into the external dirt tank. Then, a measured amount of flocculant can be added to the pretreatment tank 2. The fixing frame 12 is lowered by the spacing cylinder 11, and the servo motor 13 is turned on, allowing the mixing rod 14 to agitate the wastewater. The dirt coagulated by the flocculant can then be pushed out of the dirt inlet 7 using the push plate scraper 9 in the same way. This allows the stearate wastewater treatment device to have continuous dirt removal and chemical coagulation capabilities in the pretreatment stage. This design, through the synergistic effect of physical separation and chemical coagulation, avoids the downtime and cleaning time of traditional intermittent treatment, significantly improving treatment efficiency. Physical separation can quickly remove large particles, while chemical coagulation targets dissolved or finely suspended stearates. This dual approach prevents pipe blockage and biochemical treatment system failure. Then, the booster pump 16 is turned on, allowing the wastewater treated in pretreatment tank 2 to be directly drawn from the bottom of the pretreatment tank 2 and fed into the spray filter chamber 15. The pretreated wastewater is then evenly sprayed through the spray pipe 20 and spray head 21, making the stearate wastewater treatment process more thorough. Next, a packing frame 22 and an activated carbon filter 23 are installed below the spray pipe 20 and spray head 21. The packing frame 22 is filled with quartz. The wastewater is permeated layer by layer by sand, and then filtered by activated carbon filter 23, so that the stearate wastewater meets the requirements for discharge or recycling after treatment. Then, all the treated water enters the return tank 24 and can be discharged through the outlet pipe 25. Finally, after completing the installation and use of the stearate wastewater treatment device according to the above operations, turn off the switches of the first telescopic cylinder 4 and the second telescopic cylinder 8, turn off the switch of the spacing cylinder 11, turn off the switch of the servo motor 13, and turn off the switch of the pressurized water pump 16. If it is not used for a long time, simply disconnect the external power supply. In this way, the use of the stearate wastewater treatment device is completed.
