Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of methyl silicone oil treatment technology, and more specifically, to a methyl silicone oil viscosity classification filtration device. Background Technology

[0002] Methyl silicone oil is colorless, odorless, and non-volatile; it is insoluble in water, methanol, and ethylene glycol, but miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride, or kerosene. It has a very low vapor pressure and a high flash point and ignition point. Methyl silicone oil possesses excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness, and low surface tension. It also has a low viscosity-temperature coefficient and high compressibility.

[0003] During the reaction of methyl silicone oil, a small amount of cationic resin particles break down, which will cause trace amounts of resin ash impurities to be carried in the product. These impurities are dispersed in the silicone oil, which seriously affects the transparency of the product and the quality of methyl silicone oil. During the filtration and impurity removal process of methyl silicone oil, larger impurities often clog the mesh, resulting in poor impurity removal effect.

[0004] Furthermore, traditional methyl silicone oil filtration devices do not adjust to the filtration requirements of methyl silicone oils with different viscosities, resulting in low filtration efficiency. Therefore, a viscosity-graded filtration device for methyl silicone oils based on their different viscosities is designed. Utility Model Content

[0020] like Figure 1-5As shown, this utility model provides a methyl silicone oil viscosity classification and filtration device, including a rotary online viscometer 12, a methyl silicone oil filter, and a main control panel 2 for receiving the classification results of the rotary online viscometer 12 and controlling the activation of the methyl silicone oil filter. The methyl silicone oil filter includes a low viscosity filter, a medium viscosity filter, a high viscosity filter, and a standby filter 16. The inlet of the methyl silicone oil filter is connected to a diverter pipe, and the bottom of the methyl silicone oil filter is provided with an outlet 19. The input end of the diverter pipe is connected to a methyl silicone oil inlet pipe 11. A solenoid valve 18 is provided between the diverter pipe and the methyl silicone oil filter. The rotor 122 of the rotary online viscometer 12 is inserted into the methyl silicone oil inlet pipe 11.

[0021] Furthermore, in this embodiment, the diversion pipe is connected to the low viscosity filter, medium viscosity filter, high viscosity filter and standby filter 16 respectively through the solenoid valve 18, and each filter is provided with an exhaust valve 132 at the top. By setting the solenoid valve 18, the flow of methyl silicone oil of different viscosities into different filters can be controlled. The exhaust valve 132 can be used to discharge the gas inside the filter in time to prevent the gas from accumulating and affecting the filtration effect, and ensure the smooth progress of the filtration process.

[0022] In this embodiment, the low viscosity filter is provided with a filter element 131 inside. The shape of the filter element 131 is consistent with the shape of the low viscosity filter shell. It is made of glass fiber. The shape design of the filter element 131 can make full use of the internal space of the filter, increase the filtration area, improve the filtration efficiency, and effectively remove tiny impurities in the low viscosity methyl silicone oil.

[0023] In this embodiment, a filter bag 142 is disposed inside the medium viscosity filter. A filter bag 142 support frame 123 is disposed between the filter bag 142 and the inner wall of the medium viscosity filter. The filter bag 142 is installed on the outside of the filter bag 142 support frame 123 by clamps. The top of the filter bag 142 support frame 123 is connected to the inner top wall of the medium viscosity filter. The filter bag 142 support frame 123 provides stable support for the filter bag 142, preventing the filter bag 142 from deforming or shaking during the filtration process and extending the service life of the filter bag 142.

[0024] In this embodiment, a stainless steel filter element 151 is provided inside the high viscosity filter. The stainless steel filter element 151 is cylindrical. A cleaning assembly for scraping off impurities on its inner wall is provided inside the stainless steel filter element 151. The cleaning assembly includes a motor 152, a rotating rod 153 and several scrapers 154. The motor 152 is installed on the top of the high viscosity filter housing. The rotating rod 153 is connected to the output end of the motor 152 and is placed outside the stainless steel filter element 151 and inside the high viscosity filter housing. The motor 152 provides power to rotate the rotating rod 153.

[0025] In this embodiment, a connecting ring 155 is provided between the scraper 154 and the rotating rod 153. The connecting ring 155 is screwed to the rotating rod 153. An electric push rod 156 is provided between the connecting ring 155 and the scraper 154. The scraper 154 is an arc-shaped plate made of rubber or has bristles. The rotation of the rotating rod 153 drives the connecting ring 155 connected to it to rotate on the outside of the stainless steel filter element 151. At the same time, it drives the scraper 154 connected to it via the electric push rod 156 to rotate. The electric push rod 156 on the scraper 154 pushes the scraper 154 up and down synchronously to clean the stainless steel filter element 151. Due to the type of scraper 154, the scraper 154 makes soft contact with the stainless steel filter element 151 to avoid damage to the stainless steel filter element 151.

[0026] It should be noted that the extension length of the electric actuator 156 needs to be matched with the height of the stainless steel filter element 151 to avoid the length being too short, resulting in incomplete cleaning.

[0027] Furthermore, the reasons for using different filtration treatments for methyl silicone oils with low, medium, and high viscosities are as follows: Low-viscosity methyl silicone oil has good flowability and can quickly pass through the filter medium, making it suitable for use with high-precision filter element 131 to remove minute impurities. Medium viscosity methyl silicone oil has a moderate viscosity and relatively large impurity particles. Filter bag 142 can effectively trap these particles while maintaining high filtration efficiency. In addition, filter bag 142 is easy to replace. High-viscosity methyl silicone oil has high viscosity and poor fluidity. The impurity particles are large and easily adhere to the filter media. These impurities need to be removed regularly by mechanical cleaning (such as scraper 154) to maintain filtration efficiency.

[0028] In this embodiment, a thermometer 158 is installed on the top of both the medium viscosity filter and the high viscosity filter. The probe of the thermometer 158 is inserted into the interior of the medium viscosity filter and the high viscosity filter. The internal temperature of the filter is monitored by the thermometer 158 and displayed directly on the screen of the thermometer 158. The outer wall of both filters is provided with a spirally wound electric heating tape 157, which is fixed with tape. The outside of the electric heating tape 157 is wrapped with heat-insulating material, such as rock wool, to reduce heat loss and effectively maintain the temperature of the methyl silicone oil, preventing the viscosity from increasing due to low temperature and affecting the filtration effect.

[0029] In this embodiment, one end of the electric heating tape 157 is electrically connected to the electrical box 159 via a wire, and the other end is sealed with waterproof tape. The electrical box 159 is electrically connected to the main control panel 2 via a wire, and the electrical box 159 provides power to the electric heating tape 157. The main control panel 2 controls the power supply of the electrical box 159.

[0030] Additionally, the reason why only medium-to-high viscosity filters are equipped with electric heating tape 157 is as follows: Medium viscosity methyl silicone oil is greatly affected by temperature. The viscosity increases at low temperatures, which increases the filtration resistance. Setting an electric heating tape 157 can maintain a suitable temperature, ensure fluidity, and improve filtration efficiency.

[0031] High-viscosity methyl silicone oil has high viscosity, poor fluidity, and is more sensitive to temperature. It is prone to solidification at low temperatures, which makes filtration difficult. Electric heating tape 157 can prevent it from solidifying, ensure fluidity, maintain filtration performance, ensure stable filtration, and facilitate subsequent treatment.

[0032] In this embodiment, there is a gap between the low viscosity filter and the filter element 131, and there is also a gap between the high viscosity filter and the stainless steel filter element 151. This gap is connected to the feed inlet. The gap between the filter element 131 and the outer shell allows the liquid to be evenly distributed, improving filtration efficiency and reducing pressure loss.

[0033] In this embodiment, an inclined guide pipe is added between the feed inlet of the medium viscosity filter and the filter bag 142. The input end of the guide pipe is connected to the feed inlet, and the output end is aligned with the filter bag. The inclined guide pipe between the feed inlet and the filter bag 142 allows the methyl silicone oil to enter the filter bag 142 evenly, avoiding direct impact on the filter bag 142 and preventing damage, while improving the filtration effect.

[0034] Specifically, during viscosity classification and filtration of methyl silicone oil, the methyl silicone oil to be filtered is pumped from the storage tank to the methyl silicone oil inlet pipe 11 to ensure that the methyl silicone oil enters the methyl silicone oil filter stably and uniformly. A rotary online viscometer 12 is installed in the methyl silicone oil inlet pipe 11 (the detection of the rotary online viscometer 12 can refer to the NDJ-9S digital display rotary viscometer; the input rate of methyl silicone oil is relatively small during viscosity monitoring, and the power of the pump is increased to increase the input speed after the monitoring results are obtained). The rotary online viscometer 12 and the methyl silicone oil inlet pipe 11 are sealed to prevent leakage of methyl silicone oil. The viscosity of the methyl silicone oil is measured in real time, and the data is displayed on the built-in display 121. The staff observes the viscosity data and determines the viscosity grade (low viscosity, medium viscosity, or high viscosity) of the methyl silicone oil based on the measurement results of the viscometer. For low-viscosity methyl silicone oil, the operator controls the solenoid valve 18 through the main control panel 2 to open the corresponding diversion pipe of the low-viscosity filter, so that the methyl silicone oil flows into the low-viscosity filter. The methyl silicone oil passes through the filter element 131, and impurities are trapped on the outer surface of the filter element 131. The filtered liquid flows out from the inside of the filter element 131 and is finally discharged from the outlet 19. For medium viscosity methyl silicone oil, the operator controls the solenoid valve 18 through the main control panel 2 to open the corresponding diversion pipe of the medium viscosity filter, so that the methyl silicone oil flows into the medium viscosity filter. The methyl silicone oil enters the filter bag 142 evenly through the added inclined guide pipe. Impurities are trapped on the outer surface of the filter bag 142, and the filtered liquid flows out from the outlet 19 at the bottom of the filter bag 142. For high-viscosity methyl silicone oil, the operator controls the solenoid valve 18 through the main control panel 2 to open the corresponding diversion pipe of the high-viscosity filter, allowing the methyl silicone oil to flow into the high-viscosity filter. The methyl silicone oil passes through the stainless steel filter element 151, and impurities are trapped on the outer surface of the filter element 131. The motor 152 of the cleaning component is started periodically (it can be started when not filtering), which drives the rotating rod 153 and the scraper 154 to rotate. The electric push rod 156 on the scraper 154 pushes the scraper 154 up and down synchronously to clean the impurities on the inner wall of the filter element 131. During the filtration process, the exhaust valve 132 at the top of each filter is checked regularly to release the internal gas in time and prevent the gas from accumulating and affecting the filtration effect. The temperature inside the medium and high viscosity filters is monitored in real time by thermometer 158 to ensure that the temperature is within a suitable range. As needed, the staff can control the output power of the electric heating tape 157 to the electrical box 159 through the main control panel 2 to adjust the heating power of the electric heating tape 157 and maintain stable filtration conditions. After filtration is completed, turn off the transfer pump, rotary online viscometer 12, main control panel 2 and electric heating tape 157 in sequence. Clean or replace the used filter element 131 and filter bag 142. Perform necessary cleaning and maintenance on the stainless steel filter element 151 of the high viscosity filter to ensure the normal operation of the equipment.

[0035] It should be noted that the control method in this application is controlled by the operator operating the main control console 2. The control circuit of the main control console 2 can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. This application will not explain the control method and circuit connection in detail.
