Description

Technical Field

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

[0002] In the processing of silicone rubber, a filtration step is required to remove impurities and purify the silicone rubber, resulting in silicone rubber with a lower impurity content. Current technologies use filter assemblies or filter canisters in the filtration line to effectively filter impurities. However, since silicone rubber adheres to these assemblies or canisters, they must be disassembled and cleaned after a period of use to resume filtration. This cumbersome cleaning process in existing filter assembly or canister designs leads to reduced filtration efficiency.

[0003] A search revealed that CN211885671U discloses an organosilicon impurity filtration device, comprising a filter assembly, a filter barrel, and a drive assembly. The filter barrel has a chamber, a mounting hole, an output port, an input port, and a connection port. The drive assembly is fixedly connected to the connection port. The chamber is located inside the filter barrel and communicates with the mounting hole, output port, input port, and connection port. The output port and connection port are respectively located at both ends of the filter barrel. The mounting hole is located between the output port and the connection port, and the input port is located between the mounting hole and the connection port. An annular groove is provided on the inner wall of the filter barrel, communicating with the mounting hole. The filter assembly includes a handle and a filter screen. The filter screen passes through the mounting hole, and one end of the filter screen extends into the chamber and is inserted into the annular groove. The bottom of the handle is fixedly connected to the filter screen. This design simplifies and facilitates filter screen replacement, reducing the impact on the filtration efficiency of the organosilicon impurity filtration device.

[0004] However, the aforementioned silicone impurity filtration device still has the following problems: Due to the high viscosity of silicone, it easily adheres to the filter screen surface or impurity particles during the filtration process, making it difficult to completely separate. Even if the filter screen can intercept most of the silicone, some silicone will still remain in the impurities due to its viscosity, and will then be intercepted by the filter screen, resulting in waste of this portion of silicone during subsequent cleaning. Utility Model Content

[0005] This invention proposes a pressure filter device for organosilicon production, which solves the problem in the prior art where some silica gel residue is intercepted by the filter screen in the impurities.

[0006] The technical solution of this utility model is as follows: A pressure filter device for producing organosilicon includes a filter channel. Several insertion ports are opened along the length of the filter channel, and a filter component for filtering organosilicon passing through the filter channel is fixed in each insertion port. The filter component includes an outer frame inserted into the insertion port. A foldable pressure filter component and a lifting component for pressing and filtering impurities intercepted by squeezing the pressure filter component are provided on the inner side of the outer frame.

[0007] Preferably, a fixing ear plate is fixed at the top corner of the outer frame, the fixing ear plate is fixed to the filter channel by bolts, and a first handle is fixed on the top surface of the outer frame.

[0008] Preferably, rubber pads are fixed on both inner walls of the outer frame.

[0009] Preferably, the filter press component includes several stacked frames, and each frame has a pivot shaft rotatably connected to both ends. The pivot shafts between adjacent frames are hinged together, and a filter screen is fixed inside each frame.

[0010] Preferably, two sealing strips are fixed between the two rotating shafts at the same height position.

[0011] Preferably, the lifting component includes a bottom frame, an intercepting net is fixed to the inner side of the bottom frame, the frame at the top layer is hinged to the inner wall of the top of the outer frame, and the frame at the bottom layer is hinged to the bottom frame.

[0012] Preferably, two tie rods are fixed on both sides of the middle part of the bottom frame, and a top plate is fixed to the top of the two tie rods. The top plate is fixed to the outer frame by bolts, and a second handle is fixed to the top surface of the top plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an S-shaped upper and lower stacked frame in the filter channel, the organic silicone passing through the filter channel is filtered by the filter screen inside the multi-layer frame. On the one hand, the slope of the filter screen can buffer the flow of organic silicone, and on the other hand, it increases the contact area with organic silicone, thereby improving the filtration efficiency.

[0015] 2. In this utility model, when the filter assembly needs to be cleaned, the bolts fixing the top plate can be removed first. By pulling the second handle, the bottom frame at the bottom will be lifted by the pull rod. Then, the bottom frame will lift the bottom frame. The hinge action of the pivots on both sides of each frame can make each filter screen fold and squeeze each other, thereby squeezing out the residual silicone from the intercepted impurities. The silicone is then further filtered by the interception screen in the bottom frame and left in the outer frame, thereby improving the utilization rate of silicone. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a pressure filter device for producing organosilicon, including a filter channel 1, a plurality of insertion ports 2 are provided along the length of the filter channel 1, and a filter component 3 is fixed in each insertion port 2 to filter the organosilicon passing through the filter channel 1. The filter component 3 includes an outer frame 31 inserted into the insertion port 2, a foldable pressure filter component 32 is provided on the inner side of the outer frame 31, and a lifting component 33 is provided to press and filter the impurities intercepted by squeezing the pressure filter component 32.

[0025] Furthermore, a fixing ear plate 311 is fixed at the top corner of the outer frame 31. The fixing ear plate 311 is fixed to the filter channel 1 by bolts. A first handle 313 is fixed on the top surface of the outer frame 31. After the filter pressing component 32 has finished pressing, the fixing ear plate 311 used to fix the outer frame 31 can be removed, and the outer frame 31 can be pulled out from the insertion port 2 of the filter channel 1, so as to facilitate the overall cleaning of the filter assembly 3.

[0026] Furthermore, rubber pads 312 are fixed on the inner walls of both sides of the outer frame 31 to seal the gap between the filter press component 32 and the two sides of the outer frame 31, so as to prevent impurities from passing through and affecting the filtration capacity.

[0027] Please see Figure 2 and Figure 3 The filter press component 32 includes several stacked frame frames 321, and each frame frame 321 is rotatably connected to two ends of a pivot 323. The pivot 323 between adjacent frame frames 321 are hinged together by a hinge 324. Each frame frame 321 has a filter screen 322 fixed inside. By setting S-shaped stacked frame frames 321 inside the filter channel 1, the organic silica gel passing through the filter channel 1 is filtered by the filter screen 322 inside the multi-layer frame frames 321.

[0028] Furthermore, such as Figure 5 As shown, two sealing strips 325 are fixed between the two rotating shafts 323 at the same height position to seal the gap between the upper and lower frame 321, so as to prevent impurities from passing through and affecting the filtration capacity.

[0029] Please see Figure 2 and Figure 4 The lifting component 33 includes a bottom frame 331, with an intercepting net 332 fixed to the inner side of the bottom frame 331. The top frame 321 is hinged to the top inner wall of the outer frame 31, and the bottom frame 321 is hinged to the bottom frame 331. Two pull rods 333 are fixed on both sides of the middle part of the bottom frame 331, and a top plate 334 is fixed to the top of the two pull rods 333. The top plate 334 is fixed to the outer frame 31 by bolts. A second handle 335 is fixed to the top surface of the top plate 334. After the filter assembly 3 squeezes out the residual silicone from the intercepted impurities, it can be further filtered by the intercepting net 332 in the bottom frame 331 and remain in the outer frame 31. The fixing ear plate 311 used to fix the outer frame 31 is detachable, and the outer frame 31 can be pulled out from the insertion port 2 of the filter channel 1.

[0030] The working principle and usage process of this utility model are as follows: By setting an S-shaped upper and lower stacked frame 321 in the filter channel 1, the organic silicone passing through the filter channel 1 is filtered by the filter screen 322 inside the multi-layer frame 321. On the one hand, the slope of the filter screen 322 can buffer the flow of organic silicone, and on the other hand, it increases the contact area with organic silicone, thereby improving the filtration efficiency.

[0031] When the filter assembly 3 needs to be cleaned, the bolts fixing the top plate 334 can be removed first. By pulling the second handle 335, the bottom frame 331 at the bottom will be lifted by the pull rod 333. Then, the bottom frame 331 will lift the bottom frame 321. The hinge action of the pivot 323 on both sides of each frame 321 will allow each filter screen 322 to fold and squeeze each other, thereby squeezing out the residual silicone in the intercepted impurities. After further filtration by the interception net 332 in the bottom frame 331, it will remain in the outer frame 31. Then, the fixing ear plate 311 used to fix the outer frame 31 can be removed, and the outer frame 31 can be pulled out from the insertion port 2 of the filter channel 1, which makes it easy to clean the filter assembly 3 as a whole.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
