Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency treatment device for polypropylene foaming wastewater. Background Technology
[0002] Polypropylene foam materials are widely used in packaging, building insulation, automotive interiors, and many other fields due to their lightweight, excellent cushioning performance, heat insulation, moisture resistance, and corrosion resistance. As the industry continues to expand, the amount of wastewater generated during the polypropylene foam production process is increasing year by year. This type of wastewater has a complex composition, containing not only a large amount of polypropylene foam debris and fibrous residues, but also organic pollutants such as surfactants, stabilizers, unreacted monomers, and small amounts of oils. Direct discharge of such wastewater would cause serious pollution to water bodies, soil, and other ecological environments. Therefore, efficient treatment of this wastewater is of great environmental significance.
[0003] Existing polypropylene foaming wastewater treatment devices have several shortcomings in practical applications: First, the filtration stage often uses a single grid or filter, which is insufficient to effectively classify and intercept impurities of different sizes. Large particles can easily clog subsequent pipes or equipment, leading to unstable operation of the treatment system. Second, in the reagent mixing stage, a single-unit stirring structure is often used, resulting in poor mixing uniformity. This makes it difficult for the reagents to fully react with pollutants in the wastewater, reducing the removal efficiency of pollutants and affecting the effect of subsequent sedimentation treatment. In addition, the coordination between the various treatment units is insufficient, resulting in low overall treatment efficiency, which is difficult to meet the high efficiency and stability requirements of industrial continuous production for wastewater treatment. Therefore, we propose a high-efficiency polypropylene foaming wastewater treatment device to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency treatment device for polypropylene foaming wastewater to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-efficiency treatment device for polypropylene foaming wastewater includes: a workbench; a filter tank, an equalization tank, and a sedimentation tank are arranged on the top of the workbench; the filter tank is equipped with a first grid plate and a second grid plate; a connecting pipe is connected to one side of the filter tank; a mounting plate is movably inserted into one end of the connecting pipe; a sealing gasket abuts between the mounting plate and the connecting pipe; a filter is arranged on one side of the mounting plate; one end of the filter is connected to the filter tank; a pump body is arranged outside the equalization tank; a pipe connects the pump body and the connecting pipe. The equalization tank is equipped with a top cover, and a chemical dosing port is located on the top of the top cover. Two sets of stirring rods are rotatably mounted on the top of the top cover, and multiple sets of stirring blades are staggered on the outer sides of the two sets of stirring rods. Gears are installed on the top of both sets of stirring rods. A valve pipe is connected to the bottom of the equalization tank, and a valve body is slidably installed inside the valve pipe. A second pump body and a drainage pump are respectively installed on both sides of the sedimentation tank. A second pipe connects the pump body and the valve pipe. A drainage pipe is connected to the inlet of the drainage pump. A sewage valve is connected to the bottom of one side of the sedimentation tank.
[0007] Preferably, a threaded sleeve is fixedly installed at the bottom of the valve body, a screw is rotatably installed at the bottom of the valve pipe, the screw is threadedly connected to the inner wall of the threaded sleeve, the drain pipe is located inside the sedimentation tank, the filter is located inside the connecting pipe and connected to the filter tank, four sets of pull rods are slidably installed inside the connecting pipe, each of the four sets of pull rods has a limit plate on its outer side, each of the four sets of pull rods has a return spring sleeved on its outer side, each of the four sets of pull rods is movably inserted into the outer side of the mounting plate, and a pull ring is fixedly installed at one end of each of the four sets of pull rods, the first pump body is connected to the regulating tank, and the second pump body is connected to the sedimentation tank.
[0008] Preferably, the top of the top cover is provided with a frame, and the top of the frame is provided with a drive motor, wherein the top of one set of gears is fixedly installed on the output end of the drive motor, and the two sets of gears mesh with each other.
[0009] Preferably, a guide groove is provided on the inner wall of the valve pipe, and the valve body is slidably installed in the guide groove.
[0010] Preferably, an adjusting motor is fixedly installed at the bottom of the valve tube, and one end of the screw is fixedly installed on the output end of the adjusting motor.
[0011] Preferably, the inside of the connecting pipe is provided with four sets of sliding grooves, the four sets of limiting plates are slidably installed in the corresponding sliding grooves, and the two ends of the four sets of reset springs are respectively fixedly installed on one side of the corresponding sliding groove and one side of the corresponding limiting plate.
[0012] In this utility model, a high-efficiency polypropylene foaming wastewater treatment device is provided. By setting a pull ring, the pull rod and the limiting plate move outward in the limiting groove. At this time, the return spring is compressed, so the pull rod disengages from the mounting plate and releases the locking of the mounting plate and the filter. Thus, the filter can be taken out for replacement by pulling the mounting plate. During installation, the filter only needs to be inserted into the connecting pipe. Under the elastic force of the return spring, the pull rod returns to the mounting plate without external force, locking the mounting plate and the filter. The sealing gasket ensures the sealing of the filtration process. No additional tools are needed, which greatly simplifies the filter replacement process and saves maintenance time and labor costs. It is especially suitable for working conditions that require frequent filter replacement.
[0013] In this utility model, a high-efficiency polypropylene foaming wastewater treatment device is described. The wastewater enters the sedimentation tank for static sedimentation. Under the action of gravity, pollutants such as suspended particles in the water settle to the bottom of the tank. The supernatant after sedimentation is discharged through the drain pipe under the action of the drain pump for subsequent treatment or discharge to meet standards. The sludge and other impurities deposited at the bottom of the sedimentation tank can be discharged and cleaned regularly through the drain valve, avoiding secondary mixing of the supernatant and the bottom sludge, ensuring the stability of the water quality entering the next treatment step, and providing a good foundation for the subsequent treatment effect.
[0014] This utility model features a rational structural design. Wastewater undergoes preliminary filtration through two grid plates to remove large particulate impurities. A pump body, in conjunction with a pipeline and connecting pipe, creates negative pressure within the filter, allowing the wastewater to flow into a regulating tank after further filtration. Appropriate treatment agents are added through the agent dosing port. A drive motor rotates a connected gear, and the meshing of two sets of gears drives two sets of stirring rods to rotate in opposite directions. The stirring blades thoroughly mix the wastewater and agents, ensuring a complete reaction and preparing for subsequent treatment. After regulation, the regulating motor drives a screw to rotate, causing a threaded sleeve and valve body to slide within the valve pipe. This opens the valve pipe and activates the second pump body, allowing the mixed wastewater to enter the sedimentation tank through the second pipeline for sedimentation. This combined design achieves "pretreatment purification" through multi-stage filtration and enhances "chemical reaction efficiency" through bidirectional stirring. The synergistic effect of these two processes significantly improves the treatment effect, stability, and economy of polypropylene foaming wastewater, laying a solid foundation for subsequent sedimentation and compliant discharge.

The top of the equalization tank 3 is provided with a top cover 4, and the top of the top cover 4 is provided with a chemical dosing port 5. Two sets of stirring rods 15 are rotatably installed on the top of the top cover 4. Multiple sets of stirring blades 16 are staggered on the outer side of the two sets of stirring rods 15. Gears 17 are provided on the top of both sets of stirring rods 15. The bottom of the equalization tank 3 is connected to a valve pipe 25. A valve body 26 is slidably installed inside the valve pipe 25. Pump body 21 and drainage pump 30 are respectively provided on both sides of the sedimentation tank 12. Pipe 2 10 connects the pump body and the valve pipe 25. The inlet of the drainage pump 30 is connected to a drainage pipe 14. A sewage valve 13 is connected to the bottom of one side of the sedimentation tank 12.
[0023] In this embodiment, a threaded sleeve 27 is fixedly installed at the bottom of the valve body 26, and a screw 28 is rotatably installed at the bottom of the valve pipe 25. The screw 28 is threadedly connected to the inner wall of the threaded sleeve 27. The drain pipe 14 is located inside the sedimentation tank 12, and the filter 19 is located inside the connecting pipe 31 and connected to the filter tank 2. Four sets of pull rods 21 are slidably installed inside the connecting pipe 31. Limit plates 23 are provided on the outer side of each of the four sets of pull rods 21, and reset springs 24 are sleeved on the outer side of each of the four sets of pull rods 21. The four sets of pull rods 21 are movably inserted into the outer side of the mounting plate 18, and a pull ring 22 is fixedly installed at one end of each of the four sets of pull rods 21. Pump body 1 9 is connected to the regulating tank 3, and pump body 2 11 is connected to the sedimentation tank 12. This accurately controls the wastewater flow rate, avoids displacement of the valve body 26 due to water flow impact, and ensures the stability of wastewater transportation.
[0024] In this embodiment, a frame 6 is provided on the top of the top cover 4, and a drive motor 7 is provided on the top of the frame 6. The top of one set of gears 17 is fixedly installed on the output end of the drive motor 7. The two sets of gears 17 mesh with each other to enhance the uniformity of stirring, so that the reagent and wastewater are fully mixed and the reaction effect is improved.
[0025] In this embodiment, a guide groove is provided on the inner wall of the valve pipe 25, and the valve body 26 is slidably installed in the guide groove to ensure the smooth opening and closing of the valve pipe 25 and improve the adjustment accuracy of the valve body 26.
[0026] In this embodiment, an adjusting motor 29 is fixedly installed at the bottom of the valve pipe 25, and one end of the screw 28 is fixedly installed on the output end of the adjusting motor 29 to adapt to the needs of different water quality and treatment volume, thereby improving the automation level and ease of operation of the device.
[0027] In this embodiment, the inside of the connecting pipe 31 is provided with four sets of sliding grooves, and four sets of limiting plates 23 are slidably installed in the corresponding sliding grooves.

[0028] In this embodiment, during use, wastewater first enters the filter tank 2 and undergoes preliminary filtration through the first grid plate 201 and the second grid plate 202 to remove large particulate impurities. Upon starting the pump body 9, a negative pressure is created within the filter 19 via the pipe 8 and the connecting pipe 31. After further filtration through the filter 19, the wastewater flows into the pipe 8 through the connecting pipe 31 and is then transported to the regulating tank 3 by the pump body 9. Pulling the pull ring 22 outward causes the pull rod 21 and the limiting plate 23 to move outward within the limiting groove. At this time, the return spring 24 is compressed, causing the pull rod 21 to disengage from the mounting plate 18 and release the lock on the mounting plate 18 and the filter 19. The filter 19 can then be removed and replaced by pulling the mounting plate 18. During installation, the filter 19 is simply inserted into the connecting pipe 31. Under the elastic force of the return spring 24, the pull rod 21 returns to its original position within the mounting plate 18 without external force, locking the mounting plate 18 and the filter 19. The sealing gasket 20 ensures the sealing of the filtration process.
[0029] Wastewater entering the equalization tank 3 can be treated with appropriate chemicals through the chemical dosing port 5. The drive motor 7 is started to drive the gear 17 connected to it to rotate. Through the meshing of two sets of gears 17, the two sets of stirring rods 15 are driven to rotate in opposite directions. The stirring blades 16 thoroughly mix the wastewater and chemicals, so that the chemicals react fully with the wastewater, preparing for subsequent treatment. After the equalization is completed, the equalization motor 29 drives the screw 28 to rotate, causing the threaded sleeve 27 and valve body 26 to slide in the valve pipe 25. The valve pipe 25 is opened, and the pump body 11 is started, so that the mixed wastewater enters the sedimentation tank 12 through the pipeline 10 for sedimentation.
[0030] Wastewater entering sedimentation tank 12 is allowed to settle and settle. Suspended particles and other pollutants in the water settle to the bottom of the tank under the action of gravity. The supernatant after sedimentation is discharged through drain pipe 14 under the action of drain pump 30 for further treatment or discharge in compliance with standards. Sludge and other impurities deposited at the bottom of sedimentation tank 12 can be discharged and cleaned periodically through drain valve 13.
