Technical Field

[0001] The utility model relates to the technical field of polyvinyl butyral production and processing, and particularly relates to a continuous washing tank for producing polyvinyl butyral. Background Technique

[0002] Polyvinyl butyral is a high molecular compound, which has excellent transparency, light resistance, water resistance, heat resistance, cold resistance and film-forming properties. It is widely used as an adhesive and coating, and can also be used as a fabric treatment agent, etc. Washing is an important step in the production process of polyvinyl butyral. In this process, a washing tank is often needed, which can significantly improve the washing efficiency and quality, and at the same time reduce the labor intensity and the generation of waste water. However, there are still some defects in the actual operation of the washing tank for producing polyvinyl butyral.

[0003] The washing tank for producing polyvinyl butyral can often only achieve one washing operation at a time and is not easy to continuously carry out multiple washing treatments, which results in poor washing and processing effects of the polyvinyl butyral crude product by the device. Secondly, it will waste a lot of water resources, is not easy to realize the repeated utilization of water bodies through water circulation, and the environmental protection and energy-saving effects are not good enough. Based on this, we propose a new type of continuous washing tank for producing polyvinyl butyral. Content of the Utility Model

[0004] The purpose of the utility model is to provide a continuous washing tank for producing polyvinyl butyral, so as to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A continuous washing tank for producing polyvinyl butyral, including a water circulation tank and a frame.

The top of the other side of the washing tank monomer is provided with a supernatant extraction pipe fitting. The water circulation tank is welded on one side of the frame. Water pumps are installed between the washing liquid supply pipe fitting and the supernatant extraction pipe fitting and the water circulation tank. One end inside the water circulation tank is threadedly connected with a threaded installation cylinder. A reserved through hole matching the supernatant extraction pipe fitting is arranged on one side of the threaded installation cylinder. One end of the threaded installation cylinder is fixed with an assembly side cover matching the water circulation tank. An ultrasonic generator is installed at one end of the assembly side cover. An activated carbon filter screen is arranged inside the end of the threaded installation cylinder far away from the assembly side cover. An ultrasonic transducer oscillator electrically connected with the ultrasonic generator is installed on the activated carbon filter screen. The bottom of the washing tank monomer is clamped with an assembly bottom frame. A filter cloth cylinder for placing products is fixed at the top end inside the assembly bottom frame.

[0006] Preferably, three washing tank monomers are provided, and a one-way valve is installed between the washing tank monomer and the washing liquid supply pipe fitting, so that the washing liquid supply pipe fitting and the washing tank monomer can be protected against backflow through the one-way valve.

[0007] Preferably, a reserved liquid outlet pipe is welded to the top end inside the washing liquid supply pipe fitting.

[0008] Preferably, flange plates are welded on both the reserved liquid outlet pipe and the supernatant liquid extraction pipe fitting, facilitating the disassembly, assembly and maintenance of the reserved liquid outlet pipe and the supernatant liquid extraction pipe fitting.

[0009] Preferably, a threaded fixing cavity is arranged inside the flange plate, and a stainless steel filter screen is threadedly connected inside the threaded fixing cavity, so that the supernatant liquid extracted through the supernatant liquid extraction pipe fitting can be filtered and separated by the stainless steel filter screen.

[0010] Preferably, rubber sealing layers are vulcanized and connected to the outer side walls of the assembly side cover and the assembly bottom frame, and screws are evenly arranged between the assembly bottom frame and the washing tank monomer, enhancing the sealing and anti-slip performance of the assembly side cover and the assembly bottom frame.

[0011] Preferably, a servo motor is installed on the top of the washing tank monomer, and the output end of the servo motor is connected to a stirring shaft rod.

[0012] Preferably, pressure sensors are sequentially installed at the edge of the stirring shaft rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] (1) The continuous washing tank for producing polyvinyl butyral optimizes its own performance by installing a washing liquid supply pipe fitting, etc. On the one hand, by starting the corresponding water pump on the washing liquid supply pipe fitting, the washing liquid inside the water circulation tank can be pumped from bottom to top into the three washing tank monomers. The washing liquid surges into the filter cloth cylinder for product placement containing the crude product generated during the preparation of polyvinyl butyral, realizing automatic washing treatment. After one automatic washing process, the corresponding water pump on the supernatant extraction pipe fitting is started to pump the separated supernatant into the water circulation tank. After passing through the activated carbon filter screen set inside the threaded installation cylinder for filtration and purification, it enters the water circulation tank deeply, so that the corresponding water pump on the washing liquid supply pipe fitting can pump it into the washing tank monomer again for one washing operation. This enables the device to not only achieve the advantage of water circulation but also perform multiple continuous washing operations, thereby improving the washing effect on the product, optimizing the processing quality, and facilitating popularization. On the other hand, by using two liquid level sensors with different heights distributed on each washing tank monomer, when the external control device controls the start of the corresponding water pump on the washing liquid supply pipe fitting, the higher liquid level sensor is opened. After sensing that the introduced washing liquid rises to the corresponding position, it sends the liquid level data to the external control device, facilitating the intelligent shutdown of the corresponding water pump on the washing liquid supply pipe fitting by the control device. Moreover, when the external control device controls the start of the corresponding water pump on the supernatant extraction pipe fitting, the lower liquid level sensor is opened. After sensing that the extracted supernatant drains to the corresponding position, it sends the liquid level data to the external control device, facilitating the intelligent shutdown of the corresponding water pump on the supernatant extraction pipe fitting by the control device. This improves the intelligence and automation of the device and enhances the working efficiency.

[0015] (2) The continuous washing tank for producing polyvinyl butyral optimizes its own structure by installing an activated carbon filter screen, etc. By threadedly connecting a threaded installation cylinder at one end inside the water circulation tank, it is convenient for users to disassemble the threaded installation cylinder with the activated carbon filter screen for cleaning and maintenance. Moreover, by using the ultrasonic generator installed at one end of the assembled side cover and the ultrasonic transducer vibrator electrically connected to the ultrasonic generator installed on the activated carbon filter screen, the ultrasonic generator converts electrical energy into high-frequency energy, which is then converted into ultrasonic vibration by the ultrasonic transducer vibrator. Then, through the contact between the radiation surface of the ultrasonic transducer vibrator and the activated carbon filter screen, the high-frequency ultrasonic vibration makes the large particles on the activated carbon filter screen in a suspended state, thus avoiding clogging of the mesh holes and facilitating the continuous filtration and purification operation of the supernatant.

[0016] (3) The continuous washing tank for producing polyvinyl butyral is equipped with a stirring shaft rod, etc. When the device is actually operated, starting the servo motor can drive the stirring shaft rod to rotate, thereby driving the stirring shaft rod to mix the crude product and the washing liquid during the preparation of polyvinyl butyral inside the washing tank monomer. This facilitates the full contact between the two and improves the washing treatment effect of polyvinyl butyral. Moreover, by using the pressure sensors sequentially installed at the edge of the stirring shaft rod, the resistance during the rotational movement of the stirring shaft rod can be monitored. When the pressures monitored by the arranged pressure sensors are consistent, it indicates a high degree of mixing uniformity, which is convenient for intelligent control of the opening and closing of the stirring shaft rod.

After completing one automatic washing process, the water pump 5 corresponding to the supernatant extraction pipe fitting 6 is started, and the separated supernatant is pumped into the water circulation tank 3. After passing through the activated carbon filter screen 22 arranged inside the threaded installation cylinder 21 and being filtered and purified, it enters the water circulation tank 3 deeply, so that the water pump 5 corresponding to the washing liquid supply pipe fitting 13 can pump it into the washing tank monomer 7 again for a washing operation. This enables the device to not only achieve the advantage of water circulation but also realize multiple continuous washing operations, thereby improving the washing effect on the product, optimizing the processing quality, and facilitating popularization. At the same time, by using two liquid level sensors 11 with different heights distributed on each washing tank monomer 7, when the external control device controls the water pump 5 corresponding to the washing liquid supply pipe fitting 13 to start, the higher liquid level sensor 11 is opened.
