Description

Technical Field

[0001] This utility model relates to the technical field of polyphenylene ether processing equipment, and in particular to a cleaning device for the production of modified polyphenylene ether. Background Technology

[0002] Modified polyphenylene oxide (MPPO) is a high-performance engineering plastic produced by modifying basic MPPO through physical or chemical methods. It primarily addresses the issues of high melt viscosity and processing difficulties associated with pure MPPO, while retaining its excellent heat resistance, electrical insulation, mechanical strength, and dimensional stability. Modification methods include blending with polystyrene and polyamide, or adding glass fibers and nanofillers to improve flowability, impact strength, and functionality. Applications cover electronics, automotive, photovoltaics, water treatment, and medical devices. With the increasing demand for new energy vehicles and AI computing power, MPPO is experiencing significant growth in lithium battery modules and high-speed server copper-clad laminates, with the global market size expected to exceed 10 billion yuan by 2025. As a major production and consumption market, China has seen domestic companies like Jufeng New Materials achieve import substitution through technological breakthroughs, reducing costs by more than 25% and driving the industry towards high performance, environmental friendliness, and multi-functionality.

[0003] A quartz sand pickling device is disclosed in utility model application number 202021512079.3. Through a drive mechanism set on the lower surface of the barrel, the first rotating rod can be driven to rotate through the meshing connection between the first bevel gear and the second bevel gear when the motor is working, thereby realizing the rotation of the stirring rod. Through a transmission mechanism set between the first rotating rod and the second rotating rod, the gear can be driven to rotate through the transmission mechanism when the motor is working, thereby driving the screen cylinder to rotate, which facilitates pickling.

[0004] However, in the aforementioned quartz sand pickling device, the quartz sand placed in the mesh cylinder still needs to be cleaned after pickling. This requires manual removal of the raw material for cleaning, making the impurity removal process quite cumbersome. After the pickling process is completed, the regulating valve is opened to discharge the acid solution from the drain pipe. However, the dirt in the acid solution generally only accounts for a small portion. Direct discharge results in low acid solution utilization efficiency and easy waste of acid solution. Therefore, this utility model proposes a modified polyphenylene ether production cleaning device to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a modified polyphenylene ether (PPE) production cleaning device. This device uses a first motor to drive a first threaded rod to rotate, which in turn moves a first threaded sleeve and a slide rail, causing the screen cylinder to move up and down. A second threaded rod rotates, which in turn moves a second threaded sleeve and a moving plate, causing the screen cylinder to move horizontally. This allows the screen cylinder to switch between holding quartz sand in the pickling solution and clean water, solving the problem of manually removing the quartz sand for cleaning after pickling. The device filters out the dirt in the pickling solution through a filter screen and then returns it to the pickling tank through a return pipe, effectively extending the service life of the pickling solution.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a modified polyphenylene ether production cleaning device, including a support, a moving mechanism, a dirt removal mechanism, and an acid filtration mechanism.

[0007] A further improvement is that: a first motor is symmetrically fixed on both sides of the bracket, the first motor is synchronously powered on and off, and the second threaded rod is electrically driven by the motor.

[0008] A further improvement is that the rotating pickling mechanism includes a moving plate, a second motor, a turntable, and a screen.

The impurity removal box is located at the bottom of the support. An acid pickling tank is located on one side of the impurity removal box, and a clean water tank is located on the other side of the impurity removal box. The acid pickling tank and the clean water tank correspond to the positions of the mesh cylinder.

[0010] A further improvement is that a drain pipe is connected to the other side of the impurity removal box, and a solenoid valve is fixedly installed on the drain pipe, which is connected to the clean water tank.

[0011] A further improvement is that the acid filtration mechanism includes a filter box, a water pump, a water pipe, a filter screen, a return pipe, and a one-way valve. The filter box is located on one side of the support, and the water pump is fixedly installed on the filter box. A water pipe connects the filter box, the water pump, and the pickling tank. A filter screen is fixedly installed in the middle of the filter box. A return pipe is connected to the other side of the bottom of the filter box, and a one-way valve is fixedly installed on the return pipe.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a first motor to drive a first threaded rod to rotate, which in turn moves a first threaded sleeve and a slide rail to make the mesh cylinder move up and down.

This allows the mesh cylinder to switch between acid pickling solution and clean water, solving the problem of manually removing the quartz sand for cleaning after acid pickling.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a cleaning device for the production of modified polyphenylene ether, including a support 1, a moving mechanism, a purification mechanism, and an acid filtration mechanism. The moving mechanism includes a first threaded rod 2, a first threaded sleeve 3, a slide rail 4, a slider 5, a second threaded rod 6, a second threaded sleeve 7, and a rotating acid washing mechanism. The first threaded rod 2 is symmetrically rotated on both sides of the support 1. The first threaded sleeve 3 is threadedly fitted onto the first threaded rod 2. A slide rail 4 is fixed between the first threaded sleeves 3. A slider 5 is slidably fitted below the slide rail 4. The second threaded rod 6 is rotatably rotated below the slide rail 4. The second threaded sleeve 7 is threadedly fitted onto the second threaded rod 6. The rotating acid washing mechanism is located below the second threaded sleeve 7. A purification mechanism is located at the lower part of the support 1. An acid filtration mechanism is located on one side of the support 1. The first threaded rod 2 is symmetrically rotated on both sides of the support 1. The device is equipped with a first motor 8, which is synchronously powered on and off. The second threaded rod 6 is electrically driven by the motor. When it is necessary to switch the quartz sand between acid and water, the first motor 8 starts and drives the first threaded rod 2 to rotate, which in turn drives the first threaded sleeve 3 and the slide rail 4 to rise and fall. The slide rail 4 synchronously drives the screen cylinder 12 to move up and down. When it is necessary to move the screen cylinder 12 horizontally, the second motor 10 starts and drives the second threaded rod 6 to rotate, which in turn drives the second threaded sleeve 7 to move. The second threaded sleeve 7 synchronously drives the moving plate 9 and the screen cylinder 12 to move horizontally. The slider 5 slides along the slide rail 4 to keep the moving plate 9 stable, which facilitates the movement and switching of the screen cylinder 12 between the acid washing tank 14 and the water tank 15. This solves the problem that the raw materials need to be manually removed and cleaned after acid washing, making the impurity removal process cumbersome.

[0019] The rotating pickling mechanism includes a moving plate 9, a second motor 10, a turntable 11, and a screen cylinder 12. The moving plate 9 is fixedly installed below the second threaded sleeve 7. Slider 5 is fixedly connected to both sides of the moving plate 9. The second motor 10 is fixedly installed in the middle of the moving plate 9. The turntable 11 is rotatably installed below the moving plate 9. The output end of the second motor 10 is connected to the turntable 11 for driving. The screen cylinder 12 is fixedly installed below the turntable 11. A cleaning mechanism is installed below the screen cylinder 12. When pickling is performed, the second motor 10 starts to drive the turntable 11 to rotate. The turntable 11 synchronously drives the screen cylinder 12 to rotate, so that the polyphenylene ether in the screen cylinder 12 is in full contact with the acid solution, thereby accelerating the pickling and cleaning speed.

[0020] The impurity removal mechanism includes an impurity removal box 13, an acid pickling tank 14, and a clean water tank 15. The impurity removal box 13 is located at the bottom of the support 1. An acid pickling tank 14 is opened on one side of the impurity removal box 13, and a clean water tank 15 is opened on the other side of the impurity removal box 13. The acid pickling tank 14 and the clean water tank 15 correspond to the positions of the screen cylinder 12. The acid pickling tank 14 is filled with acid pickling solution, and the clean water tank 15 is filled with clean water, which facilitates the quick transfer of the screen cylinder 12 containing polyphenylene ether for cleaning after acid pickling, thereby improving the impurity removal efficiency.

[0021] The other side of the impurity removal box 13 is connected to a drain pipe 16, and a solenoid valve 17 is fixed on the drain pipe 16. The drain pipe 16 is connected to the clean water tank 15. When the water in the clean water tank 15 needs to be replaced, the solenoid valve 17 is opened to drain the water in the clean water tank 15 from the drain pipe 16, and then the water in the clean water tank 15 is manually refilled.

[0022] The acid filtration mechanism includes a filter box 18, a water pump 19, a water pipe 20, a filter screen 21, a return pipe 22, and a one-way valve 23. The filter box 18 is located on one side of the support 1, and the water pump 19 is fixed on the filter box 18. The water pipe 20 connects the filter box 18, the water pump 19, and the pickling tank 14. The filter screen 21 is fixed in the middle of the filter box 18, and the return pipe 22 is connected to the other side of the bottom of the filter box 18. The one-way valve 23 is fixed on the return pipe 22. After pickling is completed, the water pump 19 is started to draw the pickling solution from the pickling tank 14 through the water pipe 20 and transport it to the filter box 18. The filter screen 21 filters the impurities in the pickling solution. The filtered pickling solution is then returned to the pickling tank 14 through the return pipe 22, which extends the service life of the pickling solution and solves the problem that a small amount of dirt in the acid solution needs to be directly discharged, which easily leads to acid waste.

[0023] Before operation, the modified polyphenylene ether (PPE) production and cleaning device first injects pickling solution and clean water into the pickling tank and clean water tank respectively. Then, PPE is poured into the screen cylinder. The first motor is simultaneously energized and starts, driving the first threaded rod to rotate. The threaded engagement drives the first threaded sleeve and slide rail to descend along the first threaded rod, immersing the screen cylinder in the pickling tank. The second motor starts and drives the turntable to rotate, causing the screen cylinder to rotate within the pickling tank, ensuring that the PPE fully contacts the pickling solution and improving the pickling and impurity removal efficiency. After pickling is completed, the first motor drives the first threaded rod to reverse, causing the first threaded sleeve and slide rail to rise, lifting the screen cylinder out of the pickling tank. The motor then drives the second threaded rod to rotate, driving the second threaded sleeve... The cylinder moves to the other side, causing the moving plate to move synchronously. The slider slides along the slide rail to keep the moving plate and the screen cylinder stable. When the screen cylinder moves above the clean water tank, the motor stops the second threaded rod. The first motor is energized and drives the first threaded rod to rotate again, causing the first threaded sleeve and the screen cylinder to descend into the clean water tank to wash away the acid attached to the polyphenylene ether. When there is dirt in the acid solution, the water pump starts to draw the pickling solution out of the pickling tank and transport it to the filter box through the water pipe. The dirt is filtered by the filter screen. After filtration, the pickling solution flows back into the pickling tank through the return pipe. The one-way valve prevents the pickling solution from flowing back from the return pipe. When it is necessary to discharge clean water, the solenoid valve opens to discharge the clean water from the drain pipe.
