Description

Technical Field

[0001] This utility model relates to the field of organosilicon processing technology, and in particular to an impurity filtration device for organosilicon processing. Background Technology

[0002] Organosilicon is a class of polymeric materials with a silicon-oxygen bond (Si–O) main chain structure and containing organic groups. It possesses excellent high-temperature resistance, electrical insulation, weather resistance, and chemical stability, and is widely used in electronics, aerospace, building sealing, medical equipment, and daily chemical products. During the synthesis and processing of organosilicon, due to factors such as raw material purity, reaction byproducts, or equipment wear, a certain amount of solid impurities or unreacted particles are often generated. If these impurities are not effectively removed, they will directly affect the performance stability, service life, and application safety of the final product. Therefore, setting up an efficient and stable impurity filtration device in the organosilicon production process is a key step in ensuring product quality and process continuity.

[0003] Utility model patent CN 218392560 U discloses an impurity filtration device for organosilicon processing, including a vessel body, a cover, a motor, a protective chamber, a cam, a shifting component, a filter component, a slider, a reset component, and a support plate. By setting a filter screen with a sloping structure and combining it with a cam mechanism driven by a motor to achieve up-and-down reciprocating vibration of the filter screen, the filtration contact area is increased and impurities are prevented from accumulating and clogging. At the same time, the structural design of placing the rotating wheel and the cam in the vessel body and the cover respectively improves the convenience of overall cleaning.

[0004] However, the device still has obvious defects: its multiple filter plates are usually fixed inside the vessel body and cannot be removed as a whole at once. This means that when the filter plates need to be replaced or cleaned, they must be disassembled one by one. The operation is cumbersome and time-consuming, which seriously affects the production rhythm and equipment efficiency. Because the filter plates are difficult to disassemble quickly, some residual impurities may remain inside the filtration system for a long time, causing secondary pollution or blockage, which in turn affects the purity and quality consistency of subsequent batches of organosilicon products.

[0005] Therefore, given the shortcomings of existing technologies, such as inconvenient filter plate disassembly, low cleaning efficiency, and susceptibility to secondary pollution, we urgently need a new impurity filtration device for organosilicon processing to solve these problems. This new device should feature fully detachable filter plates, easy centralized cleaning, and support for rapid replacement. It should significantly improve operational convenience and production continuity while ensuring filtration effectiveness, better meeting the development needs of the modern chemical industry for high-purity, high-efficiency, and intelligent filtration equipment. Utility Model Content

[0006] The purpose of this invention is to provide an impurity filtration device for organosilicon processing, which solves the problem that in the prior art, multiple filter plates are usually fixedly installed inside the reactor body, making it impossible to remove them all at once. This results in the need to disassemble each filter plate individually when it needs to be replaced or cleaned, which is cumbersome, time-consuming, and seriously affects the production rhythm and equipment efficiency.

[0007] To achieve the above objectives, this utility model provides an impurity filtration device for organosilicon processing, comprising a vessel body, a top cover connected to the top of the vessel body, and a feed hopper connected to the top of the top cover;

[0008] The vessel body has lifting frames on both sides inside, and two conical filter buckets are set at the center inside. The two conical filter buckets are stacked vertically and are detachably connected by a connecting structure. Lifting plates are slidably installed inside the two lifting frames. The bottom of the lifting plate is connected to the bottom of the lifting frame through an elastic structure. A sliding groove is opened on one side of the lifting frame, and a slider is slidably connected inside the sliding groove. One end of the slider is fixedly connected to the side wall of the lifting plate. The top of the top cover has reciprocating drive structures on both sides for cooperating with the top of the adjacent slider.

[0009] The two lifting plates are connected to the sidewall of the adjacent conical filter bucket via a docking structure on the side closest to each other.

[0010] The connecting structure includes two mounting frames and several support frames. The two mounting frames are fixedly connected to the outer rings of the two conical filter buckets, and the several support frames are connected between the two mounting frames.

[0011] The lifting frame is internally connected to a guide rod, the lifting plate slides with the guide rod, and a mounting bracket is fixedly connected to one side of the lifting frame. The mounting bracket is bolted to the inner wall of the vessel.

[0012] The docking structure includes a support plate and a fixing plate. The support plate is fixedly connected to the lifting plate, and the fixing plate is fixedly connected to the adjacent mounting frame. The support plate and the fixing plate are connected by a number of positioning screws.

[0013] The elastic structure includes a buffer spring, one end of which is connected to the bottom of the lifting plate, and the other end is connected to the inner bottom of the lifting frame.

[0014] The reciprocating drive structure includes a reciprocating drive cylinder installed on the top of the top cover. The output end of the reciprocating drive cylinder is connected to an adjacent slider. A material guide cover is provided at the bottom of the inner part of the vessel body. The top of the material guide cover is fixedly connected to the bottom of the adjacent mounting frame with bolts.

[0015] This invention discloses an impurity filtration device for organosilicon processing. Through a docking structure and a detachable connection structure, the two conical filter buckets can be removed entirely from the reactor body for centralized cleaning or replacement, significantly reducing maintenance time and improving equipment availability and production continuity. Secondly, the sliding connection between the slider and the chute, the lifting plate and the lifting frame, and the elastic structure design enable the conical filter buckets to vibrate vertically, effectively preventing impurity accumulation and solving the clogging problem common in traditional filtration devices, further improving filtration efficiency and stability. Thirdly, the stacked arrangement of the conical filter buckets not only increases the filtration area per unit space but also enhances the ability to classify and remove impurities of different particle sizes, contributing to improved purity and quality consistency of organosilicon products.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, an impurity filtration device for organosilicon processing in this embodiment includes a vessel body 1, a top cover 2 connected to the top of the vessel body 1, and a feed hopper 3 connected to the top of the top cover 2.

[0026] Lifting frames 5 are provided on both sides of the interior of the vessel body 1. Two conical filter buckets 7 are provided at the center of the interior. The two conical filter buckets 7 are stacked vertically and are detachably connected by a connecting structure. Lifting plates 12 are slidably provided inside the two lifting frames 5. The bottom of the lifting plate 12 is connected to the bottom of the lifting frame 5 through an elastic structure. A sliding groove 8 is provided on one side of the lifting frame 5. A slider 9 is slidably connected inside the sliding groove 8. One end of the slider 9 is fixedly connected to the side wall of the lifting plate 12. Reciprocating drive structures for cooperating with the top of the adjacent slider 9 are provided on both sides of the top of the top cover.

[0027] The two lifting plates 12 are connected to the side wall of the adjacent conical filter hopper 7 via a docking structure on the side that is close to each other.

[0028] The workflow is as follows: At the start of use, the silicone raw material enters the vessel body 1 through the feed hopper 3 and flows into the upper conical filter hopper 7 located at the center via the channel below the top cover 2. This conical structure effectively expands the contact area between the liquid and the filter media, improving the initial filtration efficiency. Since the two conical filter hoppers 7 are arranged in a vertical stack and connected detachably via a connecting structure, when replacement or cleaning is required, the upper and lower filter hoppers can be separated from the lifting plate 12 by operating the docking structure, allowing for one-time removal and avoiding the tedious operation of disassembling filter plates one by one in traditional methods. During filtration, a reciprocating drive structure is located on both sides of the top of the top cover. It drives the slider 9 to reciprocate along the slide groove 8, causing the lifting plate 12 to slide up and down within the lifting frame 5. Simultaneously, an elastic structure is located between the bottom of the lifting plate 12 and the lifting frame 5, acting as a buffer and resetting mechanism, making the entire filtration process more stable and reliable. The movement of the slider 9 causes the lifting plate 12 to vibrate up and down, thereby achieving dynamic filtration of the conical filter hopper 7, preventing impurities from accumulating and clogging the filter screen, and improving filtration efficiency and throughput. The entire device replaces the traditional motor cam mechanism with this mechanical drive, which simplifies the structure while enhancing the stability and reliability of operation.

[0029] Example 2

[0030] Please see Figure 1-5As shown in this embodiment, an impurity filtration device for organosilicon processing includes a connection structure comprising two mounting frames 15 and several support frames 16. The two mounting frames 15 are respectively fixedly connected to the outer rings of two conical filter buckets 7, and the several support frames 16 are connected between the two mounting frames 15. Specifically, through the arrangement of the mounting frames 15 and the support frames 16, the two conical filter buckets 7 are fixed by their respective mounting frames 15, and a connection is established between them by the multiple support frames 16, forming an integral structure. This design not only enhances the connection stability between the conical filter buckets 7, but also facilitates the overall disassembly and installation operations during maintenance, achieving the effect of simplifying the filter bucket replacement or cleaning process.

[0031] The docking structure includes a support plate 11 and a fixing plate 17. The support plate 11 is fixedly connected to the lifting plate 12, and the fixing plate 17 is fixedly connected to the adjacent mounting frame 15. The support plate 11 and the fixing plate 17 are connected by several positioning screws 18. Specifically, through the arrangement of the support plate 11, the fixing plate 17, and the positioning screws 18, a firm docking relationship is established between the lifting plate 12 and the mounting frame 15. The support plate 11 is connected to the lifting plate 12, and the fixing plate 17 is connected to the mounting frame 15. The two are precisely aligned and fastened by the positioning screws 18, ensuring the positional accuracy and safety of the conical filter hopper 7 during operation, thereby improving filtration accuracy and extending the service life of the equipment.

[0032] The reciprocating drive structure includes a reciprocating drive cylinder 6 mounted on the top of the top cover 2. The output end of the reciprocating drive cylinder 6 is connected to the adjacent slider 9. A guide cover 14 is provided at the bottom of the inner part of the vessel body 1. The top of the guide cover 14 is bolted to the bottom of the adjacent mounting frame 15. Specifically, through the arrangement of the reciprocating drive cylinder 6, slider 9, and guide cover 14, the reciprocating drive cylinder 6 directly drives the slider 9 to reciprocate along the slide groove 8, thereby causing the lifting plate 12 and the conical filter bucket 7 on it to vibrate, effectively preventing the accumulation and clogging of impurity particles. The guide cover 14 is responsible for collecting the material after preliminary filtration and guiding it to the next processing step, ensuring the smooth flow of material and achieving the goal of optimizing the filtration process and improving production efficiency. At the same time, this design also reduces the need for manual intervention and improves the level of automation.

[0033] Example 3

[0034] Please see Figure 1-5As shown in this embodiment, an impurity filtration device for organosilicon processing includes a lifting frame 5 with a guide rod 10 connected inside. The lifting plate 12 slides with the guide rod 10. A mounting bracket 4 is fixedly connected to one side of the lifting frame 5 and bolted to the inner wall of the vessel body 1. Specifically, through the arrangement of the guide rod 10 and the mounting bracket 4, the guide rod 10 ensures the smooth sliding of the lifting plate 12 inside the lifting frame 5, avoiding operational instability or equipment damage caused by deviation. The mounting bracket 4 provides a stable mounting foundation for the entire lifting frame 5, enabling the device to remain stable during operation and improving the stability and reliability of the equipment.

[0035] The elastic structure includes a buffer spring 13. One end of the buffer spring 13 is connected to the bottom of the lifting plate 12, and the other end is connected to the inner bottom of the lifting frame 5. Specifically, the buffer spring 13 is located between the bottom of the lifting plate 12 and the inner bottom of the lifting frame 5, providing necessary elastic support. It can absorb the impact force caused by vibration, protect the equipment from damage, and help the lifting plate 12 to quickly return to its original position, maintaining a stable up-and-down reciprocating motion mode, thereby enhancing the filtration effect and extending the service life of the equipment.

[0036] Upon initial use, the silicone raw material enters the vessel body 1 through the feed hopper 3 and flows into the upper conical filter hopper 7 located at the center via a channel below the top cover 2. This conical structure effectively expands the contact area between the liquid and the filter media, improving the initial filtration efficiency. Two conical filter hoppers 7 are vertically stacked and detachably connected via a connecting structure. Specifically, the two conical filter hoppers 7 are fixed and connected into a single unit using the mounting frame 15 and support frame 16, enhancing the connection stability between the conical filter hoppers 7 and facilitating overall disassembly and installation during maintenance, thus simplifying the filter hopper replacement or cleaning process. During the filtration process, reciprocating drive cylinders 6 are installed on both sides of the top of the top cover 2, and their output ends are connected to sliders 9. By driving sliders 9 to reciprocate along the direction of the slide groove 8, the lifting plate 12 is driven to slide up and down within the lifting frame 5. Guide rods 10 ensure the smooth sliding of the lifting plate 12 within the lifting frame 5, avoiding operational instability or equipment damage caused by deviation. The mounting bracket 4 provides a stable mounting foundation for the entire lifting frame 5, enabling the device to remain stable during operation and improving the stability and reliability of the equipment. At the same time, the elastic structure includes a buffer spring 13, located between the bottom of the lifting plate 12 and the bottom of the inner part of the lifting frame 5, providing necessary elastic support. This not only absorbs the impact force from vibration, protecting the equipment from damage, but also helps the lifting plate 12 to quickly return to its original position, maintaining a stable up-and-down reciprocating motion mode, thereby enhancing the filtration effect and extending the service life of the equipment. Furthermore, the support plate 11 is fixedly connected to the lifting plate 12, and the fixing plate 17 is fixedly connected to the adjacent mounting frame 15. The two are precisely aligned and fastened by the positioning screws 18, ensuring the positional accuracy and safety of the conical filter bucket 7 during operation, thereby improving filtration accuracy and equipment lifespan. The guide hood 14 is located at the bottom of the vessel body 1, responsible for collecting the material after preliminary filtration and guiding it to the next processing step, ensuring smooth material flow, optimizing the filtration process, improving production efficiency, reducing the need for manual intervention, and improving the level of automation.

[0037] The beneficial effects of this impurity filtration device for organosilicon processing are mainly reflected in the following aspects: First, the design of the mounting frame 15 and support frame 16 achieves a firm connection between the two conical filter buckets 7 and facilitates overall disassembly, greatly simplifying the maintenance process and improving work efficiency. Second, the guide rod 10 and mounting bracket 4 ensure the smooth sliding of the lifting plate 12 during operation, enhancing the stability and reliability of the equipment. Third, the supporting plate 11, fixing plate 17, and positioning screw 18 work together to ensure the positional accuracy and safety of the conical filter buckets 7, further improving filtration precision and the service life of the equipment. Next, the buffer spring 13 not only absorbs the impact force from vibration, protecting the equipment from damage, but also promotes the rapid reset of the lifting plate 12, enhancing the filtration effect. Finally, the coordinated work of the reciprocating drive cylinder 6, slider 9, and guide cover 14 effectively prevents the accumulation and clogging of impurity particles, optimizes the filtration process, improves production efficiency, and reduces manual intervention.
