Description

Technical Field

[0001] This utility model relates to the field of organosilicon production technology, specifically to an organosilicon production and purification device. Background Technology

[0002] During the production of silicone resins, unreacted monomers, porogens, oligomers, and other organic impurities may remain in the silicone resin material. These impurities can affect the performance of the resin and the quality of the final product. Therefore, it is necessary to filter and purify the silicone resin material.

[0003] A search revealed that CN222567373U discloses a purification and production equipment for organosilicon resin, including a tank with an outlet pipe on one side. Several first columns are mounted on the top of the tank, and a common top plate is mounted on the top of each column. A motor is mounted on the top plate, and an L-shaped connecting plate is mounted on the bottom. A first bevel gear is rotatably mounted on the inner wall of one side of the L-shaped connecting plate. The equipment uses a motor to drive a second bevel gear, which in turn drives a auger to rotate inside the separation tank via a connecting shaft. Through the meshing of the first bevel gear, a third bevel gear, connected via a connecting pipe, a connecting plate, and the second column, drives the separation tank to rotate, thereby centrifugally separating the organosilicon resin transported through the inlet pipe. However, this purification method still has the following problems: because the organosilicon resin material is not pretreated before centrifugation, some oligomer impurities mixed with the organosilicon resin have high viscosity and easily adhere to the pores of the separation tank, hindering the filtration of impurities. Simultaneously, high viscosity increases the resistance to impurity movement, reducing separation efficiency. Utility Model Content

[0004] This invention proposes an organosilicon production and purification device, which solves the problem in the prior art that organosilicon resin materials are not pretreated before centrifugation.

[0005] The technical solution of this utility model is as follows: An organosilicon production and purification device includes a tank and a top frame fixed to the top of the tank. The tank is equipped with a driving mechanism and a filter cartridge for centrifugal filtration of organosilicon resin under the drive mechanism. The filter cartridge is equipped with a conveying mechanism that spirally conveys residual impurities in the filter cartridge upward under the synchronous drive of the driving mechanism. An outer cover is fixed to the inner side of the top of the top frame. A pre-filtration component for pre-treating organosilicon resin in conjunction with the conveying mechanism is provided inside the outer cover. A collection component is provided below the pre-filtration component for collecting impurities conveyed by the pre-filtration component and the filter cartridge respectively.

[0006] Preferably, the driving mechanism includes a motor, which is fixed to one side of the tank. A driving bevel gear is fixed to the output end of the motor, and a first driven bevel gear is fixed to the top surface of the filter cartridge. The first driven bevel gear meshes with the driving bevel gear.

[0007] Preferably, the conveying mechanism includes a shaft tube, the lower end of which extends into the filter cylinder and maintains a certain distance from the bottom wall of the filter cylinder's inner cavity. An auger is fixed to the portion of the shaft tube located inside the filter cylinder, and a second driven bevel gear is fixed to the outside of the shaft tube. The second driven bevel gear meshes with the driving bevel gear.

[0008] Preferably, the pre-filtration component includes a filter disc, the edge of which is fixed to the inner wall of the outer cover by a fixing block, and a return hood that gradually narrows towards the shaft tube from top to bottom is fixed to the bottom of the filter disc.

[0009] Preferably, a cone is fixed on the inner side of the shaft tube at the height of the upper surface of the filter disc, and a number of first through holes are opened on the shaft tube surrounding the cone. A number of spiral material plates are fixed on the outside of the shaft tube, which are arranged alternately with the first through holes. A number of second through holes are opened on the shaft tube at the height of the bottom opening inside the return hood.

[0010] Preferably, the collecting component includes a first collecting trough and a second collecting trough, and a connecting rod that fixes the first collecting trough and the second collecting trough together. The connecting rod is fixed inside the tank, and both the first collecting trough and the second collecting trough are annular structures.

[0011] Preferably, a feed hopper is fixed to the top of the top frame, and the lower end of the feed hopper extends into the shaft tube.

[0012] Preferably, a discharge pipe is fixed to one side of the bottom of the tank, and the discharge pipe communicates with the bottom cavity of the tank.

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

[0014] 1. In this utility model, the motor drives the active bevel gear to rotate. The meshing of the active bevel gear and the second driven bevel gear drives the shaft tube to rotate. During this process, the silicone resin material enters the shaft tube through the feed hopper, is dispersed by the cone, and is discharged to the filter plate through the surrounding first through hole. The silicone resin material is pre-treated by the filter plate. Due to the spiral push of the spiral material plate outside the shaft tube, the impurities intercepted on the surface of the filter plate can be pushed outward. Compared with the prior art, this utility model can further purify the resin through two treatments of pre-filtration and centrifugal filtration, ensuring that it can better exert its characteristics in the application process.

[0015] 2. In this invention, impurities pushed down from the filter disc fall into the first collection tank under the obstruction of the outer cover for collection. The pre-filtered silicone resin material passes through the return shroud and gathers again into the shaft tube through the first through hole. It is then guided to the bottom cavity of the filter cartridge. The meshing of the first driven bevel gear and the driving bevel gear drives the filter cartridge to rotate. The centrifugal force generated by the rotation of the filter cartridge performs secondary filtration on the silicone resin material. The screw conveyor of the auger continuously pushes the impurities intercepted in the filter cartridge upward until they fall from the top of the filter cartridge into the second collection tank on the periphery for collection. Compared with the prior art, this invention uses two filtrations and separates the collection of impurities. The first filtration removes larger particles of impurities, while the second filtration targets finer impurities, ensuring higher product purity and meeting the needs of high-end applications. Separating and collecting impurities helps to analyze the source of impurities and optimize the production process. Attached Figure Description

[0025] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: an organosilicon production and purification device, including a tank 1 and a top frame 2 fixed to the top of the tank 1. The tank 1 is provided with a driving mechanism 4 and a filter cartridge 3 for centrifugal filtration of organosilicon resin under the drive of the driving mechanism 4. The filter cartridge 3 is provided with a conveying mechanism 5 for spirally conveying residual impurities in the filter cartridge 3 upward under the synchronous drive of the driving mechanism 4. An outer cover 7 is fixed to the inner side of the top of the top frame 2. A pre-filtering component 6 for pre-treating organosilicon resin in conjunction with the conveying mechanism 5 is provided inside the outer cover 7. A collection component 8 is provided below the pre-filtering component 6 for collecting the impurities conveyed by the pre-filtering component 6 and the filter cartridge 3 respectively.

[0026] Please see Figure 2 and Figure 4 The drive mechanism 4 includes a motor 41, which is fixed to one side of the tank 1. The output end of the motor 41 is fixed with a drive bevel gear 42. The top surface of the filter cartridge 3 is fixed with a first driven bevel gear 31. The first driven bevel gear 31 meshes with the drive bevel gear 42. When the motor 41 works, it drives the drive bevel gear 42 to rotate. Through the meshing of the first driven bevel gear 31 and the drive bevel gear 42, the filter cartridge 3 can be driven to rotate. Then, the centrifugal force generated by the rotation of the filter cartridge 3 performs secondary filtration on the silicone resin material.

[0027] Please see Figure 2 and Figure 3 The conveying mechanism 5 includes a shaft tube 51, the lower end of which extends into the filter cylinder 3 and maintains a certain distance from the bottom wall of the inner cavity of the filter cylinder 3. An auger 52 is fixed to the part of the shaft tube 51 located inside the filter cylinder 3. A second driven bevel gear 54 is fixed to the outside of the shaft tube 51. The second driven bevel gear 54 meshes with the driving bevel gear 42. The motor 41 drives the driving bevel gear 42 to rotate. Under the meshing of the driving bevel gear 42 and the second driven bevel gear 54, the shaft tube 51 can be driven to rotate. Under the spiral conveying of the auger 52, the impurities intercepted in the filter cylinder 3 can be continuously pushed upward.

[0028] Please see Figure 2 , Figure 4 and Figure 6The pre-filtration component 6 includes a filter disc 61. The edge of the filter disc 61 is fixed to the inner wall of the outer cover 7 by a fixing block 71. A return shroud 62, which gradually narrows from top to bottom towards the shaft tube 51, is fixed to the bottom of the filter disc 61. A cone 55 is fixed to the inner side of the shaft tube 51 at the height of the upper surface of the filter disc 61. Several first through holes 56 are opened on the shaft tube 51, surrounding the cone 55. Several spiral material plates 53, alternating with the first through holes 56, are fixed to the outside of the shaft tube 51. Several second through holes are opened on the shaft tube 51 at the height of the bottom opening inside the return shroud 62. Through hole 57, silicone resin material enters the shaft tube 51 through the feed hopper 21. After being dispersed by cone 55, it is discharged to filter plate 61 through the surrounding first through hole 56. The silicone resin material is pre-treated by the filter plate 61. Due to the spiral push of the spiral material plate 53 outside the shaft tube 51, the impurities intercepted on the surface of the filter plate 61 are pushed outward and fall into the first collection tank 81 for collection under the obstruction of the outer cover 7. The pre-filtered silicone resin material is then collected again in the shaft tube 51 through the return cover 62 and the first through hole 56, and then guided to the bottom cavity of the filter cartridge 3 by the shaft tube 51.

[0029] Please see Figure 2 and Figure 3 The conveying and collecting component 8 includes a first collecting trough 81 and a second collecting trough 82, and a connecting rod 83 that fixes the first collecting trough 81 and the second collecting trough 82 together. The connecting rod 83 is fixed inside the tank body 1. Both the first collecting trough 81 and the second collecting trough 82 are annular structures. The spiral push of the spiral material plate 53 outside the shaft tube 51 can push the impurities intercepted on the surface of the filter disc 61 outward and fall into the first collecting trough 81 for collection under the obstruction of the outer cover 7. The spiral conveying of the auger 52 can continuously push the impurities intercepted in the filter cylinder 3 upward until they fall into the outer second collecting trough 82 from the top opening of the filter cylinder 3 for collection.

[0030] Furthermore, a feed hopper 21 is fixed to the top of the top frame 2, and the lower end of the feed hopper 21 extends into the shaft tube 51, allowing the silicone resin material to enter the shaft tube 51 through the feed hopper 21.

[0031] Furthermore, a discharge pipe 11 is fixed to one side of the bottom of the tank 1. The discharge pipe 11 is connected to the bottom cavity of the tank 1 and can discharge the silicone resin material that has been filtered twice in the bottom cavity of the tank 1 through the discharge pipe 11.

[0032] The working principle and usage process of this utility model are as follows: The motor 41 drives the active bevel gear 42 to rotate. Under the meshing of the active bevel gear 42 and the second driven bevel gear 54, the shaft tube 51 can be rotated. During this process, the silicone resin material enters the shaft tube 51 through the feed hopper 21, is dispersed by the cone 55, and is discharged to the filter plate 61 through the surrounding first through hole 56. The silicone resin material is pre-treated by the filter plate 61. Due to the spiral push of the spiral material plate 53 outside the shaft tube 51, the impurities intercepted on the surface of the filter plate 61 can be pushed outward, and the outer cover 7 provides resistance. The filtered silicone resin material falls into the first collection tank 81 for collection. The pre-filtered silicone resin material passes through the return hood 62 and the first through hole 56 and is gathered again into the shaft tube 51. The shaft tube 51 guides it to the bottom cavity of the filter cartridge 3. The first driven bevel gear 31 and the driving bevel gear 42 mesh to drive the filter cartridge 3 to rotate. The centrifugal force generated by the rotation of the filter cartridge 3 performs secondary filtration of the silicone resin material. The screw conveyor of the auger 52 can continuously push the impurities intercepted in the filter cartridge 3 upward until they fall from the top of the filter cartridge 3 into the second collection tank 82 on the periphery for collection.

[0033] 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.
