Technical Field

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

[0002] Methyl silicone oil is a synthetic lubricant based on silicon oxides (siloxanes), also known as polysiloxanes. This oil is a polymer composed of repeating units of silicon and oxygen. In the production process of methyl silicone oil, the high-speed filtration stage is an important step in the post-processing stage, which mainly involves the purification of the product and the removal of impurities.

[0003] Traditional methyl silicone oil filtration devices rely solely on gravity for natural permeation. When the viscosity of the silicone oil increases or impurities increase, the filtration speed rapidly decreases. Furthermore, the colloidal impurities in high-viscosity silicone oil easily accumulate at the filter pores, causing frequent clogging. Therefore, a filtration device for processing methyl silicone oil with more stable filtration was designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a filtration device for processing methyl silicone oil.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a filtration device for processing methyl silicone oil, including a methyl silicone oil filter barrel. At least two filter plates are disposed inside the outer shell of the methyl silicone oil filter barrel, including a primary filter plate and a secondary filter plate. A methyl silicone oil extrusion mechanism is disposed inside the outer shell. The methyl silicone oil extrusion mechanism includes a hydraulic propulsion component, a pressure plate, and guide components for propulsion guidance. The hydraulic propulsion component is disposed on the upper inner side of the outer shell. The pressure plate is disposed at the bottom of the hydraulic propulsion component and above the primary filter plate. An extrusion block is disposed on the bottom surface of the pressure plate. Guide components are disposed on both sides of the hydraulic propulsion component. The outer side of the outer shell is wrapped with a methyl silicone oil filter barrel insulation layer.

[0006] Preferably, the hydraulic propulsion component includes a cylinder and a piston rod. The cylinder is disposed at the top of the housing, and the piston rod is disposed at the output end of the cylinder, extending through the housing. A connecting block for connecting to the piston rod is screwed to the upper surface of the pressure plate.

[0007] Preferably, the surface of the pressure plate is threaded with a plurality of extrusion blocks, the cross-section of the extrusion blocks is conical or trapezoidal, the size of the extrusion blocks is adapted to the filter holes of the primary filter plate, and the extrusion blocks are made of metal.

[0008] Preferably, the guide includes two connecting sleeves and a guide rod. The two connecting sleeves are respectively connected to the outer shell and the pressure plate screw. The connecting sleeves are sleeved on the upper and lower ends of the guide rod, and the cross-section of the guide rod is designed in the shape of an "I".

[0009] Preferably, the insulation layer of the methyl silicone oil filter barrel is bonded to the outer surface of the methyl silicone oil filter barrel, and the methyl silicone oil filter barrel is an electric heating tape wrapped with ceramic fiber felt on the outside, and the electric heating tape is connected to an external electrical box through wires.

[0010] Preferably, a thermometer is installed on the top of the methyl silicone oil filter barrel, and the probe of the thermometer is located at the inner top of the outer casing.

[0011] Preferably, a filter cleaning assembly is provided at the inner bottom of the outer casing. The filter cleaning assembly includes a water pipe and several nozzles. The water pipe has a ring design, and the nozzles are connected to the water pipe. A water pump is connected to the water pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model accelerates the filtration of methyl silicone oil by setting up hydraulic extrusion to progressive mechanical pressure, and clears the filter holes by extrusion block, thus getting rid of the drawbacks of slow gravity penetration and frequent clogging in traditional methods, and achieving continuous and efficient filtration.

[0016] (2) By setting up an electric heat tracing cable to keep the filter device warm, the ceramic fiber felt conducts heat evenly, so that the temperature inside the barrel is kept constant at the suitable temperature of the methyl silicone oil.

[0020] like Figure 1-5As shown, this utility model provides a filtration device for processing methyl silicone oil, including a methyl silicone oil filter barrel 1. At least two filter plates are provided inside the outer shell 101 of the methyl silicone oil filter barrel 1, including a primary filter plate 102 and a secondary filter plate 103. A methyl silicone oil extrusion mechanism 2 is provided inside the outer shell 101. The methyl silicone oil extrusion mechanism 2 includes a hydraulic propulsion component, a pressure plate 204, and a guide component for propulsion guidance. The hydraulic propulsion component is located on the upper side inside the outer shell 101. The pressure plate 204 is located at the bottom of the hydraulic propulsion component and above the primary filter plate 102. An extrusion block 207 is provided on the bottom surface of the pressure plate 204. The guide component is located on both sides of the hydraulic propulsion component. The outer shell 101 is wrapped with a methyl silicone oil filter barrel insulation layer 5.

[0021] Furthermore, in this embodiment, the hydraulic propulsion component includes a cylinder 201 and a piston rod 202. The cylinder 201 is located at the top of the housing 101, and the piston rod 202 is located at the output end of the cylinder 201. The piston rod 202 penetrates through the housing 101. A connecting block 203 for connecting with the piston rod 202 is screwed onto the upper surface of the pressure plate 204. The pressure plate 204 is connected to the hydraulic propulsion component through the connecting block 203, so that the hydraulic propulsion component provides a vertical thrust to the pressure plate 204. The hydraulic propulsion component provides uniform pressure, which presses down the methyl silicone oil on the primary filter plate 102 at a uniform speed, forcing the silicone oil to quickly pass through the filter holes to complete the initial filtration.

[0022] It should be noted that the hydraulic propulsion component is an existing hydraulic push rod, and its propulsion principle is existing technology, which will not be elaborated further.

[0023] In this embodiment, the surface of the pressure plate 204 is threaded with a plurality of extrusion blocks 207. The cross-section of the extrusion block 207 is conical or trapezoidal. The size of the extrusion block 207 is adapted to the filter holes of the primary filter plate 102. The extrusion block 207 is made of metal. The position of the extrusion block 207 is aligned with the position of the filter holes of the primary filter plate 102. The pressure plate 204 moves towards the primary filter plate 102. Through mechanical extrusion, the residues on the primary filter plate 102, such as gel-like silicone oil or particulate impurities, can be removed.

[0024] In this embodiment, the guide component includes two connecting sleeves 206 and a guide rod 205. The two connecting sleeves 206 are respectively screwed to the outer shell 101 and the pressure plate 204. The connecting sleeves 206 are sleeved on the upper and lower ends of the guide rod 205. The cross-section of the guide rod 205 is designed in the shape of an "I". The two guide rods 205 slide synchronously in the connecting sleeves 206. Through the cooperation between the "I" shaped guide rods 205 and the two connecting sleeves 206, they move synchronously when the hydraulic propulsion component is pressing down, thereby improving stability.

[0025] In this embodiment, the insulation layer 5 of the methyl silicone oil filter barrel is bonded to the outer surface of the methyl silicone oil filter barrel 1. The methyl silicone oil filter barrel 1 is an electric heating tape 501 wrapped with ceramic fiber felt on the outside. The electric heating tape 501 is connected to an external electrical box through wires. The heat of the electric heating tape 501 is conducted through the ceramic fiber felt. The electric heating tape 501 is controlled by the electrical box to prevent the methyl silicone oil from solidifying at low temperature and to ensure the continuous filtration process. It is especially suitable for high viscosity silicone oil or cold environments, avoiding overheating degradation of silicone oil or low temperature clogging of filter plates.

[0026] In this embodiment, a thermometer 4 is installed on the top of the methyl silicone oil filter barrel 1. The probe of the thermometer 4 is located at the inner top of the outer shell 101. The temperature inside the methyl silicone oil filter barrel 1 is monitored in real time by the thermometer 4. The staff can directly check the temperature on the thermometer 4 and thus perform heat preservation / heating treatment on the methyl silicone oil filter barrel 1 in a timely manner.

[0027] It should be noted that methyl silicone oil of normal viscosity needs to be stored in an environment of 40-60℃. If high temperature occurs, you can choose to let it stand to cool down or use conventional cooling methods such as air cooling.

[0028] In this embodiment, a filter tank cleaning assembly 3 is provided at the bottom inner part of the outer casing 101. The filter tank cleaning assembly 3 includes a water pipe 301 and several nozzles 302. The water pipe 301 has a ring design, and the nozzles 302 are connected to the water pipe 301. A water pump 303 is connected to the water pipe 301. The nozzles 302 are equipped with a filter screen with small filter holes to block methyl silicone oil. After filtration is completed and the methyl silicone oil is discharged, clean water is sprayed from the nozzles 302 through the cooperation of the water pump 303 and the water pipe 301 to perform coarse cleaning of the methyl silicone oil filter tank 1, providing a basis for subsequent fine cleaning.

[0029] It should be noted that the water pipe 301 is designed as a ring to fit with the frame of the filter plate, reducing the possibility of methyl silicone oil flowing into the nozzle 302 and clogging it. The water pipe 301 and the outer casing 101 are designed to be detachable, which facilitates the cleaning and maintenance of the nozzle 302. Specifically, the detachable design can be achieved by setting the bottom of the outer casing 101 as an openable and closable cover, or other existing methods. Furthermore, the clogging of the nozzle 302 by methyl silicone oil is unavoidable. If the nozzle 302 is clogged, the water pressure of the water pump 303 can be increased to flush out the methyl silicone oil blocking the nozzle 302. If the water flow cannot clear the blockage, the clogged nozzle 302 can be manually cleared after the cleaning work is completed.

[0030] In this embodiment, a waste liquid outlet 106 is provided at the bottom center of the methyl silicone oil filter tank 1. The bottom cross section of the methyl silicone oil filter tank 1 is "V" shaped, and the waste liquid outlet 106 is located at the lowest position. Gravity is used to make the waste liquid (containing impurities) gather at the lowest point and completely drain it through the waste liquid outlet 106 to avoid residual corrosion of the equipment.

[0031] Furthermore, since the cleaning component is only performed after the methyl silicone oil has been completely discharged, the waste liquid outlet 106 at the bottom can also be used to discharge the methyl silicone oil. The methyl silicone oil can be discharged through both the waste liquid outlet 106 and the methyl silicone oil outlet 105 at the same time, reducing the time that the methyl silicone oil spends on the nozzle 302.

[0032] In this embodiment, a methyl silicone oil inlet 104 is provided on the upper side near the methyl silicone oil filter tank 1. The methyl silicone oil inlet 104 is located between the primary filter plate 102 and the pressure plate 204, ensuring that the methyl silicone oil is first filtered by the primary filter plate 102 and then assisted by the pressure plate 204, thus preventing unfiltered silicone oil from directly entering the secondary filter plate 103 and optimizing the efficiency of the filtration stages.

[0033] In this embodiment, a methyl silicone oil outlet 105 is provided on one side near the bottom of the methyl silicone oil filter tank 1. The methyl silicone oil outlet 105 is horizontally / vertically offset from the filter tank cleaning assembly 3. The methyl silicone oil outlet 105 is also offset from the water pipe 301. The offset is to prevent the methyl silicone oil from being retained, solidified, and blocked at the nozzle 302 when it is drawn out by the suction pump. When horizontally offset, the outlet and the nozzle 302 are not on the same radial section. When the suction pump is pumping oil, the liquid flow flows tangentially along the tank wall, reducing the chance of silicone oil directly impacting or being retained at the nozzle 302. When vertically offset, if the nozzle 302 is higher than the outlet, the liquid level drops when the suction pump is pumping oil, and the nozzle 302 is above and not submerged by oil. If the nozzle 302 is lower than the outlet, the small amount of residual silicone oil will flow naturally to the waste liquid discharge outlet 106 due to gravity and will not flow back upward to cover the nozzle 302.

[0034] Specifically, before filtration, check whether the thermometer 4, electric heating tape 501, electrical box, water pump 303, suction pump, oil cylinder 201 and pipeline connections are intact, confirm that the waste liquid outlet valve 106 is closed and the methyl silicone oil outlet valve 105 is open, start the electric heating tape 501 in the electrical box, and the ceramic fiber felt will evenly heat the barrel wall. Monitor the temperature in real time through the top thermometer 4 to keep the temperature inside the barrel stable at 40-60℃. If the temperature is too high, the electric heating tape 501 can be temporarily turned off or the air cooling / static method can be used to cool down. Methyl silicone oil is injected through the injection port at a steady rate, and the oil level must not exceed the initial position of the pressure plate 204. Under the action of gravity, the methyl silicone oil passes through the primary filter plate 102, where large particles of impurities are trapped. At the same time, the piston rod 202 of the oil cylinder 201 is controlled by the remote control to move slowly and uniformly toward the primary filter plate 102. The pressure plate 204 is vertically downward based on the guide rod 205, and the entire pressure plate 204 applies uniform pressure to the silicone oil, accelerating the initial filtration through the filter holes. As the pressure plate 204 continues to descend, the extrusion blocks 207 are aligned with and pass through the filter holes of the primary filter plate 102 one by one, removing gel-like silicone oil or particulate impurities and clearing the filter holes. After primary filtration, the silicone oil continues to fall to the secondary filter plate 103, where fine impurities are further removed. The methyl silicone oil after secondary filtration collects at the bottom of the tank. A suction pump is used to extract the filtered silicone oil through the methyl silicone oil outlet 105. When the liquid level is close to the lower edge of the outlet, the waste liquid outlet valve 106 can be opened simultaneously to extract the oil in parallel from both sides, shortening the oil discharge time and reducing the residence of silicone oil at the nozzle 302. The power supply to the electric heating tape 501 is then cut off to complete this filtration operation. After the oil is drained, turn off the suction pump and start the water pump 303. Clean water is sprayed out from the nozzle 302 through the water pipe 301 to initially rinse the barrel wall and the two-stage filter plates. The nozzle 302 has a built-in filter screen to block large particles of impurities, reducing the risk of the nozzle 302 being blocked. If the nozzle 302 is blocked, the pressure of the water pump 303 is increased for a short time to flush in reverse. If it is still ineffective, the blockage is manually cleared after the cleaning is completed. The cleaning wastewater flows along the bottom of the barrel to the waste liquid outlet 106 to completely empty the barrel until the waste liquid is completely discharged.

[0035] It is worth noting that the control method in this application is through a remote control. The control circuit of the remote control can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. Therefore, this application will not explain the control method and circuit connection in detail.
