Description

Technical Field

[0001] This utility model relates to the field of pressure filtration technology, specifically to a pressure filtration device for organosilicon. Background Technology

[0002] Because organosilicon is a heavy pollutant, the filter residue it discharges needs to be thoroughly filtered to reduce the wastewater content in the residue to over 95% to avoid environmental damage. Therefore, current methods often employ hydraulic pressure filtration, where the immense pressure allows the wastewater to be fully extruded from the filter residue.

[0003] Chinese Patent CN215970238U discloses a pressure filtration device for organosilicon, relating to the field of pressure filtration technology. The device includes a machine body with an internal cavity. A screw is mounted on the output end of a motor, and a pressure plate is rotatably connected to the side surface of the screw. A filter plate is mounted on one end of a limiting rod, and a sludge discharge mechanism is mounted on one side of the machine body. This invention, by incorporating a motor, screw, pressure plate, limiting rod, and filter plate, enables the output end of the motor to drive the screw to rotate when the motor starts, thereby causing the pressure plate to move up and down for pressure filtration. This design effectively avoids the problem of functional damage to telescopic rods or hydraulic rods caused by long-term use, which affects the quality of the finished organosilicon product. It provides a more stable and efficient operation of the equipment and ensures the quality of the produced organosilicon.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the pressure plate squeezes the silicone raw material onto the filter plate, which can easily cause the filter holes on the filter plate to become clogged. Furthermore, the other filter plates located below are also prone to clogging after a period of filtration, interfering with the pressure filtration efficiency. Utility Model Content

[0018] Example 1

[0019] like Figure 1 and Figure 4 As shown, the present invention proposes a pressure filtration device for organosilicon, including an outer barrel 1 and a pressure filtration mechanism; a support leg 102 is provided at the bottom of the outer barrel 1, and a drain valve 101 is provided at the bottom of the outer circumference of the outer barrel 1; the pressure filtration mechanism is located inside the outer barrel 1 and is used to filter organosilicon.

[0020] The filter press mechanism includes a filter press barrel 2, a second lifting mechanism 3, and a cleaning component. The filter press barrel 2 is installed on the outer barrel 1. A feed valve 205 is provided on the side wall of the filter press barrel 2, located above the outer barrel 1. A base 201 is detachably installed at the bottom of the filter press barrel 2. Several sets of filter holes 204 are evenly arranged on the side wall of the filter press barrel 2, and the filter holes 204 are located inside the outer barrel 1 and distributed on the filter press barrel 2. The second lifting mechanism 3 is located at the top of the filter press barrel 2. The output end of the second lifting mechanism 3 extends into the interior of the filter press barrel 2 and is equipped with a piston plate 301. The second lifting mechanism 3 is prior art, and its specific structure and principle are detailed in the patent with authorization announcement number CN215970238U, and will not be repeated here. The piston plate 301 is slidably connected to the inner wall of the filter press barrel 2. The cleaning component is located at the top of the second lifting mechanism 3 and is used to clean the inner wall of the filter press barrel 2 to prevent the filter holes 204 from becoming clogged.

[0021] Furthermore, two sets of mounting cavities 202 are symmetrically arranged on the filter press 2. A first lifting mechanism 203 is installed inside the mounting cavity 202. The base 201 is installed between the output ends of the two sets of first lifting mechanisms 203. The first lifting mechanism 203 is connected to the bottom end of the filter press 2. The first lifting mechanism 203 is an electric push rod. The first lifting mechanism 203 is activated to drive the base 201 to move down away from the filter press 2, so as to move the compressed organic silicon raw material to the outside of the filter press 2 for easy material removal. The first lifting mechanism 203 drives the base 201 to move up and press against the filter press 2, so as to seal the open end of the bottom of the filter press 2 for easy filtration.

[0022] Furthermore, an air inlet valve 206 and a pressure relief valve 207 are provided on the side wall of the filter press 2. The air inlet valve 206 is connected to an external air supply mechanism, which facilitates the input of inert gas into the filter press 2 to achieve a pressurization effect and improve pressure efficiency.

[0023] Furthermore, the cleaning assembly includes a support frame 302 and a cleaning brush 303; the support frame 302 consists of an annular seat and support blocks, with multiple sets of support blocks evenly installed at the top edge of the second lifting mechanism 3, and the annular seat installed between the multiple sets of support blocks; the cleaning brush 303 is annular, installed on the outer wall of the annular seat, and the bristles on the cleaning brush 303 contact the inner wall of the filter press 2; when the second lifting mechanism 3 drives the piston plate 301 to move along the inner wall of the filter press 2, the cleaning brush 303 can clean and move the material on the inner wall of the filter press 2, while preventing the filter holes 204 from being blocked and interfering with the filter discharge.

[0024] In this embodiment, an appropriate amount of organosilicon raw material is fed into the filter press 2 through the feed valve 205 and the valve port of the feed valve 205 is closed. The external gas supply mechanism is connected to the air inlet valve 206 to supply inert gas into the filter press 2. After that, the external gas supply mechanism is disconnected from the air inlet valve 206. The input of inert gas into the filter press 2 does not interfere with the filtration of organosilicon, but increases the air pressure inside the filter press 2. When the second lifting mechanism 3 is activated and moves down along the inner wall of the filter press 2, it facilitates the filtration of organosilicon and further improves the filtration efficiency. The liquid in the organosilicon is discharged into the filter press 2 through multiple sets of filter holes 204. The silicone is discharged from the outer barrel 1 through the drain valve 101. After the filter press is completed, the pressure relief valve 207 is activated to release the pressure inside the filter press barrel 2. At this time, the piston plate 301 can continue to slide down along the inner wall of the filter press barrel 2 through the second lifting mechanism 3 to push the silicone downward, so that the silicone accumulates on the base 201. The base 201 is driven down away from the filter press barrel 2 by the first lifting mechanism 203, so that the silicone can be transported to the outside of the filter press barrel 2 for easy removal. When the piston plate 301 is driven up and down along the inner wall of the filter press barrel 2 by the second lifting mechanism 3, the cleaning brush 303 can be driven to clean the filter press barrel 2, while avoiding the filter holes 204 from being blocked and avoiding interference with the filter press efficiency.

[0025] Example 2

[0026] like Figures 1 to 3 As shown, the present invention proposes a silicone pressure filtration device. Compared with Embodiment 1, the pressure filtration barrel 2 is rotatably connected to the outer barrel 1. The outer barrel 1 is provided with a driving mechanism for driving the pressure filtration barrel 2 to rotate along the outer barrel 1. The driving mechanism includes a driving component 4 and a transmission assembly. The driving component 4 is installed on the outer barrel 1. The output end of the driving component 4 is connected to a transmission rod. The transmission assembly is disposed between the transmission rod and the pressure filtration barrel 2.

[0027] Furthermore, the transmission assembly consists of a drive gear 401 and a driven gear ring 402 meshing with the drive gear 401. The drive gear 401 is mounted on the transmission rod, and the driven gear ring 402 is mounted on the filter press barrel 2.

[0028] In this embodiment, after the organosilicon enters the filter press 2 through the feed valve 205, the feed valve 205 is closed. The drive component 4 is a motor. The drive component 4 starts the drive transmission rod to rotate, which in turn drives the drive gear 401 to rotate, causing the driven gear ring 402 connected to it to rotate, which in turn drives the filter press 2 to rotate, which in turn drives the organosilicon raw material inside the filter press 2 to rotate. Under the action of centrifugal force, the filtration is further accelerated, so that the liquid can be thrown out from the filter hole 204 into the outer barrel 1, and then discharged by the drain valve 101.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
