Description

Technical Field

[0001] The present invention relates to the technical field of silicone pressure filtration, and specifically to an automatic pressure filtration device and method for silicone. Background Art

[0002] Since silicone is highly polluting, the filter residues discharged therefrom need to be fully filtered so that the wastewater content in the filter residues is reduced to more than 95% to prevent environmental damage. Therefore, the existing methods often use hydraulic extrusion for pressure filtration, and the huge pressure can fully squeeze out the wastewater from the filter residues.

[0003] However, a relatively large hydraulic pressure needs to be applied slowly and cannot quickly reach the pressure standard value in a short time. At the same time, pressure filtration can only be carried out quantitatively each time, resulting in low pressure filtration efficiency. Therefore, centrifugal filtration is also used in the existing methods. Although the centrifugal filtration method improves the efficiency, the silicone slurry is relatively thick, resulting in the inability of centrifugal filtration to effectively reduce the water content in the filter residues. Summary of the Invention

[0004] The technical problem of the present invention is to provide an automatic pressure filtration device and method for silicone, which can perform extrusion while performing centrifugal filtration, and the two functions are synchronized, greatly improving the filtration efficiency and ensuring extremely low water content.

[0005] To achieve the above object, the present invention provides the following technical solution: an automatic pressure filtration device for silicone, including a filter cylinder, a partition mechanism is arranged inside the filter cylinder, the partition mechanism includes a pressure filtration plate and a telescopic plate, a plurality of pressure filtration plates are arranged in an array along the axis direction of the filter cylinder inside the filter cylinder, and each pressure filtration plate is connected by a plurality of telescopic plates and spaced at equal intervals. The lowermost pressure filtration plate is rotationally connected to the filter cylinder in a limited manner. It further includes a spline rotating cylinder slidably connected to the pressure filtration plate. A motor capable of driving the spline rotating cylinder to rotate is arranged below the filter cylinder. An upper feeding pipe is arranged inside the spline rotating cylinder. A plurality of conveying pipes are communicated with the upper feeding pipe. One end of the conveying pipe far from the upper feeding pipe is communicated between two adjacent pressure filtration plates.

[0007] As a further solution of the present invention, the inflation device includes an inflation box fixedly connected to the air pressure box. The upper surfaces of the inflation box and the air pressure box are communicated through a pipeline, and a one-way valve is arranged in the pipeline. An inflation piston is connected in the inflation box in a limited sliding manner. A spring capable of resetting the inflation piston is arranged on the inflation piston. The upper end of the spline barrel is fixedly connected with a cam. An air inlet nozzle containing a one-way valve is arranged on the inflation box. A cam capable of pushing the inflation piston to move into the inflation box is fixedly connected to the spline barrel. A spring capable of resetting the air pressure plate upward is sleeved on the push rod two.

[0008] As a further solution of the present invention, a plurality of blanking mechanisms are further arranged on the filter cartridge. The blanking mechanism includes a baffle plate slidably connected to the thin wall of the filter cartridge. A fixing ring is fixedly connected between the baffle plates of the plurality of blanking mechanisms. A discharge port is opened on the filter cartridge at the position of the baffle plate, and a slag discharge port is opened on the baffle plate.

[0009] As a further solution of the present invention, the blanking mechanism further includes a switching mechanism. The switching mechanism includes a limiting frame fixedly connected above the baffle plate, and further includes a pressing rod fixedly connected to the push rod two and slidably connected in the limiting frame in a limited manner. An installation block is fixedly connected to the filter cartridge. Two limiting blocks are slidably connected in the installation block in a limited manner. A spring capable of resetting the limiting blocks toward the direction close to the fixing ring is arranged on the installation block.

[0010] As a further solution of the present invention, a pressure relief pipe communicated with the cam is connected to the upper end of the air pressure box. The pressure relief pipe is rotatably connected to the cam. A valve seat is communicated with the pressure relief pipe. A second sliding rod is fixedly connected to the fixing ring. A first sliding rod is slidably connected in the second sliding rod in a limited manner. The upper end of the first sliding rod is fixedly connected with a valve block slidably connected in the valve seat. A spring capable of resetting the first sliding rod downward is arranged on the first sliding rod. A communication hole is opened on the valve block. An air inlet is opened on the spline barrel at the position between the two pressure filter plates and close to the telescopic plate.

[0011] As a further solution of the present invention, an air discharge pipe communicated with the air inlet is fixedly connected to the inner wall of the arc-shaped contour of the spline barrel. The end of the air discharge pipe far from the spline barrel is fixedly connected with a sealing frame. A trapezoidal block is slidably connected in the air discharge pipe in a limited manner. An arc-shaped baffle capable of closing the air inlet is fixedly connected to the end of the trapezoidal block far from the sealing frame.

[0012] As a further solution of the present invention, a first push rod is fixedly connected to the outer wall of the first sliding rod. A wedge block is slidably connected to the lower surface of the air pressure box in a limited manner. A spring capable of resetting the wedge block toward the side away from the first push rod is arranged on the wedge block.

[0013] As a further solution of the present invention, the specific steps of the usage method of the automatic pressure filtration device for silicone are as follows:

[0014] Step 1: Waste liquid is conveyed between the pressure filtration plates through the feeding pipe. Subsequently, the motor starts to work. The motor drives the spline rotating cylinder to rotate, thereby driving all the pressure filtration plates to rotate synchronously. Due to the existence of the telescopic plate, the waste liquid will be pushed by the telescopic plate and rotate simultaneously. Under the action of centrifugal force, the waste liquid will quickly pass through the filtration holes on the thin wall of the filter cylinder, thus completing the filtration function.

[0015] Step 2: While the pressure filtration plates are rotating for filtration, the rotation of the spline rotating cylinder will drive the cam to rotate, and thus continuously inflate the air pressure box through the pneumatic piston. As a result, the air pressure plate will push the push rod two downward, so that the connecting ring will push the limit block to move the pressure filtration plate downward. Therefore, the pressure filtration plate will squeeze the waste liquid between the pressure filtration plates, so as to cooperate with the centrifugal action of the pressure filtration plate to fully filter the waste liquid.

[0016] Step 3: The movement of the push rod two will simultaneously drive the pressure rod to move downward. When the pressure filtration plate contracts completely, that is, the telescopic plate completely contracts. At this time, the pressure rod will move to the lowest end of the limit frame, thereby pushing the material blocking plate downward. As a result, the slag discharge port will coincide with the discharge port and open. The material blocking plate will drive the fixed ring to move at the same time, and thus drive the sliding rod two to pull the sliding rod one to move downward at the same time. The downward movement of the sliding rod one will drive the valve block to move downward, so that the communication hole will communicate with the pressure relief pipe. Therefore, the compressed air above the air pressure plate in the air pressure box will be conveyed into the spline rotating cylinder through the pressure relief pipe and then blown into the filter cylinder through the air inlet. At this time, with the centrifugal cooperation of the rotation of the pressure filtration plate and the air blown out of the air inlet, the filter residue can be quickly discharged.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Different from the prior art, this technology can perform extrusion filtration while performing centrifugal filtration. The two functions are carried out simultaneously, which not only has higher efficiency, but also can fully filter the wastewater, greatly reducing the moisture content of the filter residue. This technology is provided with multiple pressure filtration plates, so the single filtration volume will not be lower than that of the existing equipment during a single filtration. At the same time, the pressure filtration plates are separated by telescopic plates, which can prevent the separated filtrate from flowing in the pressure filtration plates and ensure that the filtrate can quickly flow out of the filter cylinder.

[0019] 2. Different from the prior art, the air in the air inflation box is continuously introduced into the air pressure box by the cam pushing the pneumatic piston, without a separate power source, with low use cost and simple structure. At the same time, the load in the air inflation box will not be too large by the air extrusion method, so it will not affect the rotation of the spline rotating cylinder, and thus will not affect the centrifugal filtration. At the same time, the air push is not likely to damage the telescopic plate by extrusion.

[0020] 3. This technology can discharge materials while the device is still operating, thus ensuring work efficiency. At the same time, the rotation of the filter pressing plate is utilized to achieve material discharge, enabling automatic material discharge when the filtration is completed. The structure is simple and does not require a separate power source, with low usage costs. Moreover, since the end of the telescopic plate far from the spline drum closely adheres to the inner wall of the filter drum, the telescopic plate can scrape the inner wall of the filter drum, thereby reducing the possibility of filter residue adhering to the inner wall of the filter drum.

[0021] 4. During filtration, the arc-shaped baffle will block the air inlet, preventing the waste liquid from flowing into the spline drum. When the filtration is completed, the fixed ring will drive the valve block to move downward to automatically open the valve block, allowing the compressed air in the air pressure tank to blow into the spline drum, achieving the function of relieving pressure in the air pressure tank and enabling the air pressure plate to automatically reset, facilitating the next filtration. At the same time, the relieved air can be blown into the filter pressing plate, thereby cooperating with centrifugal material discharge to improve the speed and effect of material discharge.

Specific Embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0036] Please refer to Figures 1 to 10 , the present invention provides a technical solution: an automatic filter press device for organosilicon, including a filter cartridge 01. A partition mechanism is arranged in the filter cartridge 01. The partition mechanism includes a filter press plate 20 and a telescopic plate 28. A plurality of filter press plates 20 are arranged in the filter cartridge 01 in an array along the axis direction of the filter cartridge 01, and each filter press plate 20 is connected and equally spaced apart by a plurality of telescopic plates 28. The lowermost filter press plate 20 is rotatably connected to the filter cartridge 01 in a limited manner. It also includes a spline rotating cylinder 02 slidably connected to the filter press plate 20. A motor 19 capable of driving the spline rotating cylinder 02 to rotate is arranged below the filter cartridge 01. A feeding pipe 32 is arranged in the spline rotating cylinder 02. A plurality of conveying pipes 30 are communicated with the feeding pipe 32. One end of the conveying pipe 30 away from the feeding pipe 32 is communicated into the space between two adjacent filter press plates 20. An extrusion device capable of squeezing the filter press plate 20 downward is also arranged above the filter cartridge 01.

[0037] Connect the feeding pipe 32 and the wastewater conveying pipe. Subsequently, the wastewater will be conveyed into two adjacent filter plates 20 through the conveying pipe 30. There is wastewater conveyance inside each filter plate 20 separated by the telescopic plate 28. Subsequently, the motor 19 starts to work, driving the spline drum 02 to rotate. The spline drum 02 will drive all the filter plates 20 to rotate synchronously. At the same time, the telescopic plate 28 will also be driven by the filter plates 20 to rotate simultaneously. Thus, the telescopic plate 28 will push the waste liquid inside the filter plates 20 to rotate. Thus, under the action of centrifugal force, the wastewater will quickly flow out through the filter cylinder 01, while the filter residue will remain inside the filter plates 20, thus completing the filtering function. While the filter plates 20 are rotating for filtration, the extrusion device will also work, driving the uppermost filter plate 20 to move downward. Thus, all the filter plates 20 will gradually contract downward until the telescopic plate 28 is completely contracted, thus realizing the function of extruding between all the filter plates 20. Cooperating with the centrifugal filtering function, sufficient filtration is achieved;

[0038] Different from the prior art, this technology can perform extrusion filtration while performing centrifugal filtration. The two functions are carried out simultaneously, not only with higher efficiency, but also enabling the wastewater to be fully filtered, greatly reducing the moisture content of the filter residue; this technology is provided with multiple filter plates 20. Therefore, the single - time filtration amount will not be lower than that of the existing equipment during single - time filtration. At the same time, the filter plates 20 are separated by the telescopic plates 28, which can prevent the separated filtrate from flowing inside the filter plates 20, ensuring that the filtrate can quickly flow out of the filter cylinder 01.

[0039] As a further solution of the present invention, the extrusion device includes a pneumatic box 04. Inside the pneumatic box 04, there is a pneumatic plate 27 slidably connected. The lower surface of the pneumatic plate 27 is fixedly connected with a second push rod 17. The lower end of the second push rod 17 is fixedly connected with a connecting ring 21. On the uppermost filter plate 20, there is a limit block 22 fixedly connected and slidably connected with the connecting ring 21. The extrusion device further includes an inflation device that can make the pneumatic plate 27 move downward.

[0040] As a further solution of the present invention, the inflation device includes an inflation box 05 fixedly connected to the pneumatic box 04. The inflation box 05 and the upper surface of the pneumatic box 04 are connected through a pipeline, and a one - way valve is arranged inside the pipeline. Inside the inflation box 05, there is an inflation piston 23 slidably connected with a limit. A spring is arranged on the inflation piston 23 to make the inflation piston 23 reset. The upper end of the spline drum 02 is fixedly connected with a cam 03. An air inlet nozzle 06 containing a one - way valve is arranged on the inflation box 05. The spline drum 02 is fixedly connected with a cam 03 that can push the inflation piston 23 to move into the inflation box 05. A spring that can make the pneumatic plate 27 reset upward is sleeved on the second push rod 17.

[0041] When the spline drum 02 rotates, it will drive the cam 03 to rotate at the same time. When the cam 03 rotates, it will intermittently push the inflation piston 23 to move into the inflation box 05. Thus, when the cam 03 rotates, it will intermittently push the inflation piston 23 to move into the inflation box 05. Subsequently, the inflation box 05 can continuously transport the outside air into the pressure box 04 above the pressure plate 27. As the pressure above the pressure plate 27 continuously increases, it will push the pressure plate 27 to slide downward, driving the second push rod 17 to move downward. The second push rod 17 will push the uppermost filter pressing plate 20 downward, causing the telescopic plate 28 to contract until the telescopic plate 28 contracts to the last section. At this time, all the filter pressing plates 20 are closest to each other. When the filter pressing plates 20 contract, they can also rotate simultaneously with the spline drum 02, thus realizing centrifugal filtration while performing extrusion filtration.

[0042] It is different from the prior art that the cam 03 is used to push the inflation piston 23 to continuously introduce the air in the inflation box 05 into the pressure box 04. It does not require a separate power source, has low use cost and a simple structure. At the same time, the load in the inflation box 05 will not be too large by the air extrusion method, so it will not affect the rotation of the spline drum 02, thus not affecting the centrifugal filtration. At the same time, the air push is not likely to cause damage to the telescopic plate 28 by extrusion.

[0043] As a further solution of the present invention, a plurality of blanking mechanisms are further provided on the filter cylinder 01. The blanking mechanism includes a baffle plate 15 slidably connected to the thin wall of the filter cylinder 01. A fixed ring 25 is fixedly connected between the baffle plates 15 of the plurality of blanking mechanisms. A discharge port 14 is provided on the filter cylinder 01 at the position of the baffle plate 15, and a slag discharge port 31 is provided on the baffle plate 15.

[0044] As a further solution of the present invention, the blanking mechanism further includes a switching mechanism. The switching mechanism includes a limiting frame 16 fixedly connected above the baffle plate 15, and further includes a pressure rod 18 fixedly connected to the second push rod 17 and slidably connected in the limiting frame 16. Two limiting blocks 24 are slidably connected to the filter cylinder 01 on the fixing block 13, and a spring is provided on the fixing block 13 to reset the limiting blocks 24 in the direction close to the fixed ring 25.

[0045] During the centrifugal filtration process, as the filter pressing plate 20 gradually contracts, when the filter pressing plate 20 is fully contracted, the filter residue is fully filtered. When the push rod two 17 pushes the filter pressing plate 20 downward, at the same time, the push rod two 17 will drive the pressure rod 18 downward. The pressure rod 18 will slide downward within the limit frame 16. When the filter pressing plate 20 is fully contracted, at the same time, the pressure rod 18 will move to the lowest end of the limit frame 16 and push the fixed ring 25 downward, thereby pushing all the baffle plates 15 downward. As a result, the slag discharge port 31 on the baffle plate 15 will coincide with the discharge port 14. At this time, the filter pressing plate 20 is still rotating. When the telescopic plate 28 rotates, the filter residue can be driven to move when the telescopic plate 28 rotates. Thus, under the action of centrifugal force, the filter residue can be thrown out of the filter cylinder 01 through the discharge port 14, thereby realizing the function of discharging the filter residue from the filter cylinder 01. A conveying pipeline can be externally connected to the discharge port 14 to achieve discharge;

[0046] This technology can carry out feeding while the device is not stopped, thus ensuring the working efficiency. At the same time, the rotation of the filter pressing plate 20 is utilized to achieve feeding, and automatic feeding can be realized when the filtration is completed. The structure is simple and does not require a separate power source, with low usage cost. And since the end of the telescopic plate 28 far from the spline rotating cylinder 02 closely adheres to the inner wall of the filter cylinder 01, the telescopic plate 28 can scrape the inner wall of the filter cylinder 01, thereby reducing the possibility of filter residue adhering to the inner wall of the filter cylinder 01.

[0047] As a further solution of the present invention, the upper end of the air pressure box 04 is connected to a pressure relief pipe 37 that is connected to the cam 03. The pressure relief pipe 37 is rotatably connected to the cam 03. A valve seat 07 is connected to the pressure relief pipe 37. A second sliding rod 10 is fixedly connected to the fixed ring 25. A first sliding rod 09 is slidably connected within the second sliding rod 10 in a limited manner. The upper end of the first sliding rod 09 is fixedly connected to a valve block 08 that is slidably connected within the valve seat 07. A spring is provided on the first sliding rod 09 to enable the first sliding rod 09 to reset downward. A communication hole 26 is opened on the valve block 08. An air inlet 36 is opened on the spline rotating cylinder 02 at a position between the two filter pressing plates 20 and close to the telescopic plate 28.

[0048] As a further solution of the present invention, an air discharge pipe 29 that is connected to the air inlet 36 is fixedly connected to the inner wall of the arc-shaped contour of the spline rotating cylinder 02. The end of the air discharge pipe 29 far from the spline rotating cylinder 02 is fixedly connected to a sealing frame 33. A trapezoidal block 34 is slidably connected within the air discharge pipe 29 in a limited manner. The end of the trapezoidal block 34 far from the sealing frame 33 is fixedly connected to an arc-shaped block 35 that can block the air inlet 36.

[0049] When the filtration is completed, during the process that the pressing rod 18 pushes the limiting frame 16 to move the fixing ring 25 downward to open the baffle 15, the fixing ring 25 will drive the second sliding rod 10 downward at the same time, so that the second sliding rod 10 will pull the first sliding rod 09 downward. When the first sliding rod 09 moves downward, it will pull the valve block 08 downward. When the discharge port 14 is opened, the communication hole 26 on the valve block 08 can coincide with the pressure relief pipe 37 at this time, so that the upper part of the air pressure plate 27 in the air pressure box 04 is communicated with the spline rotating cylinder 02. Thus, the compressed air above the air pressure plate 27 will quickly release pressure into the spline rotating cylinder 02 through the pressure relief pipe 37, and then be sent into the space between the filter pressing plates 20 through the air discharge pipe 29. When blowing into the air discharge pipe 29, it will push the trapezoidal block 34 to move towards the inner side of the filter pressing plate 20 at the same time. Thus, the trapezoidal block 34 will push the arc-shaped baffle 35 to move towards the inner side of the filter pressing plate 20, so that the arc-shaped baffle 35 no longer blocks the air inlet 36, and the air inlet 36 is opened, so that the air flow in the spline rotating cylinder 02 can be blown into the filter pressing plate 20 through the air inlet 36. At this time, the slag discharge port 31 and the discharge port 14 coincide and open, so that the air flow can be blown out from the discharge port 14. The blowing of the air flow can assist the filter residue to be discharged from the discharge port 14, improving the feeding speed, especially for the broken slag. When the air in the air pressure box 04 is sent into the spline rotating cylinder 02, under the action of the spring on the second push rod 17, the air pressure plate 27 will reset upward, thus driving the filter pressing plate 20 to reset upward. All the filter pressing plates 20 and the telescopic plates 28 will expand. When discharging pressure, the pressure relief speed of the pressure relief pipe 37 is much greater than the inflation speed of the inflation box 05;

[0050] When filtering, the arc-shaped baffle 35 will block the air inlet 36, so that the waste liquid will not flow into the spline rotating cylinder 02. When the filtering is completed, at the same time, the fixing ring 25 will drive the valve block 08 downward to automatically open the valve block 08, so that the compressed air in the air pressure box 04 is blown into the spline rotating cylinder 02, realizing the function of pressure relief in the air pressure box 04, making the air pressure plate 27 automatically reset, facilitating the next filtration. At the same time, the air released from pressure can be blown into the filter pressing plate 20, so as to cooperate with the centrifugal feeding to improve the feeding speed and effect.

[0051] As a further solution of the present invention, a first push rod 11 is fixedly connected to the outer wall of the first sliding rod 09, a wedge block 12 is connected to the lower surface of the air pressure box 04 in a limited sliding manner, and a spring is arranged on the wedge block 12 to reset the wedge block 12 towards the side away from the first push rod 11.

[0052] When the pressure rod 18 pushes the fixed ring 25 downward and the baffle plate 15 opens, at this time, the communication hole 26 coincides with the pressure relief pipe 37. When the fixed ring 25 drives the first slide rod 09 downward, when the discharge port 14 opens, at this time, the first slide rod 09 will also drive the first push rod 11 downward and just move to the position of the wedge block 12. When the cam 03 rotates at this time, it can intermittently push the wedge block 12 in the direction of the first push rod 11, so that the wedge block 12 can intermittently push the first push rod 11 upward, so that the communication hole 26 will intermittently move upward and be misaligned with the pressure relief pipe 37, so as to realize intermittent pressure relief into the spline drum 02. Whenever pressure is relieved into the spline drum 02, the air pressure will push the trapezoidal block 34 to open the arc-shaped baffle 35, and then reset under the action of the spring. Therefore, the arc-shaped baffle 35 can be intermittently opened, and intermittent air leakage between the filter pressing plates 20 can be realized. Since after the filtration is completed, the moisture content of the filter residue is relatively low, and through the extrusion of the filter pressing plates 20, the filter residue may form lumps. The rapidly flowing air during pressure relief can break up the lumps by the impact action, so as to facilitate discharge. At the same time, intermittent aeration can intermittently open the arc-shaped baffle 35, so that the arc-shaped baffle 35 can also play a role in pushing the filter residue. Since the telescopic plate 28 is continuously rotating, the filter residue can always be on one side of the telescopic plate 28. For example Figure 9 , when the telescopic plate 28 rotates clockwise, the filter residue will be located on the side of the telescopic plate 28 close to the arc-shaped baffle 35. Therefore, the air flow and the push of the arc-shaped baffle 35 can always act on the filter residue.

[0053] As a further solution of the present invention, the specific steps of the usage method of the automatic filter pressing device for organosilicon are as follows:

[0054] Step 1: Feed the waste liquid between the filter pressing plates 20 through the feeding pipe 32. Then the motor 19 starts to work, and the motor 19 will drive the spline drum 02 to rotate, so as to drive all the filter pressing plates 20 to rotate synchronously. Due to the existence of the telescopic plate 28, the waste liquid will be pushed by the telescopic plate 28 and rotate at the same time. Therefore, under the action of centrifugal force, the waste liquid will quickly pass through the filter holes on the thin wall of the filter cylinder 01 and be discharged, thus completing the filtering function;

[0055] Step 2: While the filter pressing plates 20 are rotating for filtration, the rotation of the spline drum 02 will drive the cam 03 to rotate at the same time, so that the pneumatic piston 23 can continuously inflate into the pneumatic box 04. Therefore, the pneumatic plate 27 will push the second push rod 17 downward, so that the connecting ring 21 will push the limit block 22 to make the filter pressing plates 20 move downward. Therefore, the filter pressing plates 20 will squeeze the waste liquid between the filter pressing plates 20, so as to cooperate with the centrifugal action of the filter pressing plates 20 to make the waste liquid be fully filtered;

[0056] Step 3: The movement of the second push rod 17 will simultaneously drive the hole punching pressure rod 18 downward. When the filter pressing plate 20 is fully retracted, that is, the telescopic plate 28 is fully retracted, at this time, the pressure rod 18 will move to the lowermost end of the limit frame 16, thereby pushing the material baffle 15 downward, so that the slag discharge port 31 will coincide with the discharge port 14 and open. The material baffle 15 will simultaneously drive the fixed ring 25 to move, thereby driving the second sliding rod 10 to pull the first sliding rod 09 downward at the same time. The downward movement of the first sliding rod 09 will drive the valve block 08 downward, so that the communication hole 26 will communicate with the pressure relief pipe 37. Thus, the compressed air above the air pressure plate 27 in the air pressure tank 04 will be transported into the spline rotary cylinder 02 through the pressure relief pipe 37, and then blown into the filter cartridge 01 through the air inlet 36. At this time, with the centrifugal force of the rotation of the filter pressing plate 20 and the air blown out through the air inlet 36, the filter residue can be quickly discharged.

5. A method for using an automated pressure filtration device for silicone, applicable to the automated pressure filtration device for silicone described in claim 4, characterized in that: The specific steps of the using method of the automatic filter pressing device for organosilicon are as follows: Step 1: Waste liquid is conveyed between the filter pressing plates (20) through the feeding pipe (32). Subsequently, the motor (19) starts to work. The motor (19) drives the spline rotating cylinder (02) to rotate, thereby driving all the filter pressing plates (20) to rotate synchronously. Due to the existence of the telescopic plate (28), the waste liquid will be pushed by the telescopic plate (28) and rotate simultaneously. Thus, under the action of centrifugal force, the waste liquid will quickly pass through the filtering holes on the thin wall of the filter cylinder (01) and be discharged, thereby completing the filtering function; Step 2: While the filter pressing plate (20) rotates for filtration, the rotation of the spline barrel (02) will drive the cam (03) to rotate simultaneously, so that the inflation piston (23) can continuously inflate into the air pressure box (04). As a result, the air pressure plate (27) will push the second push rod (17) downward, so that the connecting ring (21) will push the limit block (22) to move the filter pressing plate (20) downward. Thus, the filter pressing plate (20) will squeeze the waste liquid between the filter pressing plates (20), so as to cooperate with the centrifugal action of the filter pressing plate (20) to fully filter the waste liquid. Step 3: The movement of the second push rod (17) will drive the pressure rod (18) to move downward at the same time. When the filter pressing plate (20) is completely retracted, that is, the telescopic plate (28) is completely retracted. At this time, the pressure rod (18) will move to the lowest end of the limit frame (16), so as to push the baffle plate (15) downward. As a result, the slag discharge port (31) will coincide with the discharge port (14) and open. The baffle plate (15) will drive the fixed ring (25) to move at the same time, so as to drive the second slide rod (10) to pull the first slide rod (09) to move downward at the same time. The downward movement of the first slide rod (09) will drive the valve block (08) to move downward, so that the communication hole (26) will communicate with the pressure relief pipe (37). Thus, the compressed air above the air pressure plate (27) in the air pressure box (04) will be transported into the spline barrel (02) through the pressure relief pipe (37), and then blown into the filter cartridge (01) through the air inlet (36). At this time, with the centrifugal cooperation of the rotation of the filter pressing plate (20) and the air blown out of the air inlet (36), the filter residue can be quickly discharged.
