Description

Technical Field

[0001] This utility model relates to the field of epoxy resin production technology, specifically to an electronic-grade epoxy resin centrifuge. Background Technology

[0002] Epoxy resin is a type of organic polymer containing two or more epoxy groups in its molecular structure. It is a thermosetting plastic. Electronic grade epoxy resin contains two or more epoxy groups in its molecular chain, forming a three-dimensional network structure. It has excellent mechanical properties and heat resistance. In the production process of electronic grade epoxy resin, centrifuges are required to separate the epoxy resin from impurities.

[0003] Current electronic-grade epoxy resin centrifuges, such as the one disclosed in CN221108593U, include a frame with a top-wide, bottom-narrow structure at the lower middle part of the frame. A discharge trough is located at the center of the bottom of the frame, and a centrifuge cylinder is located at the center of the frame's interior. A steering cylinder is fixedly installed at the center of the top of the centrifuge cylinder, communicating with the interior of the centrifuge cylinder, with its top extending to the outside of the frame. This invention uses a centrifuge cylinder, steering cylinder, slider, cleaning sleeve, and dual-shaft motor to force the centrifuge cylinder to intermittently float up and down. This achieves centrifugal dispersion while simultaneously cleaning the resin liquid adhering to the filter screen, preventing the liquid from drying out and sticking, thus affecting the mesh dispersion effect.

[0004] While existing electronic-grade epoxy resin centrifuges can assist in cleaning resin liquid adhering to the filter screen to prevent it from drying out and sticking, thus affecting the dispersion effect of the mesh, it has been found that during the separation of epoxy resin and impurities in the centrifuge drum, impurities gradually adhere to the inner wall of the drum. After the centrifuge drum sieve holes become clogged, the inner wall of the drum needs to be cleaned by staff. During cleaning, the epoxy resin centrifuge needs to be shut down for a long time, resulting in low epoxy resin production efficiency and inconvenience. Therefore, we have proposed an electronic-grade epoxy resin centrifuge to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an electronic-grade epoxy resin centrifuge to solve the problems currently existing in the market as described in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic-grade epoxy resin centrifuge, comprising a base, on both sides of the top of which centrifuge tanks and cleaning tanks are symmetrically mounted, and the outer sides of the centrifuge tanks and cleaning tanks near the bottom are respectively connected to a discharge pipe and a drain pipe, wherein...

[0007] A turntable is rotatably connected to the top center of the base. A hydraulic rod is installed on the top of the turntable, and a lifting frame is installed on the top of the hydraulic rod. The turntable is driven to rotate by a drive mechanism. Support pipes are installed on the lifting frame at the positions corresponding to the centrifuge tank and the cleaning tank. A sieve cylinder is rotatably connected to the outer side of the support pipe near the bottom. A tank cover is fixedly installed on the outer side of the support pipe near the top of the sieve cylinder.

[0008] The support tube is symmetrically provided with feed inlets on the outer side inside the screen cylinder. The top opening of the support tube is sealed with a sealing cap. A second motor is installed on the cover of the barrel. A drive gear is installed on the shaft end of the second motor. A ring gear is installed on the top of the screen cylinder corresponding to the drive gear. The cleaning barrel is provided with a backwashing mechanism for cleaning the screen cylinder. A drain outlet is provided at the bottom of one side of the screen cylinder. The drain outlet is sealed with a sealing plug.

[0009] Preferably, the drive mechanism includes a first motor, which is installed on the lower part of the base near the center. A first reversing gear is installed on the shaft end of the first motor, and a second reversing gear is installed on the rotating shaft end of the turntable corresponding to the first reversing gear.

[0010] Preferably, the pitch of the driving gear is equal to the pitch of the ring gear, and the driving gear meshes with the ring gear.

[0011] Preferably, the base is symmetrically equipped with fixing rods on both sides of the top near the turntable, and the top of the fixing rods is provided with positioning grooves. The bottom of the lifting frame is fixedly connected with positioning rods corresponding to the positioning grooves.

[0012] Preferably, the outer diameter of the positioning rod matches the inner diameter of the positioning groove, and the bottom end of the positioning rod is chamfered.

[0013] Preferably, the backwashing mechanism includes a U-shaped tube, which is installed inside the cleaning tank. The bottom end of the U-shaped tube is connected to a water inlet pipe, and spray holes are equidistantly opened on the side of the U-shaped tube near the side wall of the screen cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the hydraulic rod, via the lifting frame and support pipe, can drive the two screen cylinders to rise and fall. The drive mechanism can then rotate the turntable, allowing the two screen cylinders to switch positions. This enables the screen cylinders to enter the centrifuge tank and the cleaning tank respectively. This allows the epoxy resin centrifuge to separate epoxy resin from impurities through centrifugation, while simultaneously cleaning the other screen cylinder via a backwashing mechanism inside the cleaning tank. This avoids the need for prolonged shutdown of the epoxy resin centrifuge to clean the inner wall of the screen cylinder, effectively improving the processing efficiency of epoxy resin.

[0016] In this invention, when the hydraulic rod drives the lifting frame to fall, allowing the screen cylinders on both sides to enter the centrifuge tank and the cleaning tank, the lifting frame drives the positioning rod to enter the positioning groove. The positioning structure formed by the positioning rod and the positioning groove can keep the lifting frame stable and prevent the lifting frame from shaking when the screen cylinder rotates.

[0017] This invention allows for automatic cleaning of the screen cylinder when cleaning is required. The sealing plug at the bottom of the screen cylinder is opened, allowing the cylinder to enter the cleaning tank. A second motor drives the screen cylinder to rotate, while flushing water enters the U-shaped pipe through the inlet pipe and is then sprayed out through the nozzles to backwash the side walls of the screen cylinder. Impurities adhering to the inner wall of the screen cylinder are discharged through the bottom drain port and then discharged from the cleaning tank through the drain pipe. This backwashing mechanism automatically cleans the inner wall of the screen cylinder, eliminating the need for manual cleaning, improving cleaning efficiency, and saving labor costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3This utility model provides a technical solution: an electronic-grade epoxy resin centrifuge, including a base 1, with centrifuge tanks 2 and cleaning tanks 3 symmetrically installed on the top of both sides of the base 1. The outer sides of the centrifuge tanks 2 and 3 near their bottoms are respectively connected to a discharge pipe 4 and a drain pipe 5.

[0024] A turntable 6 is rotatably connected to the top center of the base 1. A hydraulic rod 7 is installed on the top of the turntable 6. A lifting frame 8 is installed on the top of the hydraulic rod 7. The turntable 6 is driven to rotate by a drive mechanism. Support pipes 12 are installed on the lifting frame 8 at the positions corresponding to the centrifuge tank 2 and the cleaning tank 3. A sieve cylinder 13 is rotatably connected to the outer side of the support pipe 12 near the bottom. A tank cover 14 is fixedly installed on the outer side of the support pipe 12 near the top of the sieve cylinder 13.

[0025] The support tube 12 is located inside the screen cylinder 13 and has symmetrically opened feed inlets 15 on the outer side. The top opening of the support tube 12 is sealed by a sealing cap 16. A second motor 17 is installed on the barrel cover 14. A drive gear 18 is installed on the shaft end of the second motor 17. A ring gear 19 is installed on the top of the screen cylinder 13 corresponding to the drive gear 18. The cleaning barrel 3 is equipped with a backwashing mechanism for cleaning the screen cylinder 13. A drain port 26 is opened on the bottom side of the screen cylinder 13. The drain port 26 is sealed by a sealing plug 27.

[0026] The hydraulic rod 7 can drive the two screen cylinders 13 to rise and fall through the lifting frame 8 and the support pipe 12. The drive mechanism can drive the turntable 6 to rotate, thereby changing the position of the two screen cylinders 13. This allows the two screen cylinders 13 to enter the centrifuge tank 2 and the cleaning tank 3 respectively. This allows the epoxy resin centrifuge to separate epoxy resin from impurities through centrifugation, while the backwashing mechanism inside the cleaning tank 3 cleans the other screen cylinder 13. This avoids the epoxy resin centrifuge from being shut down for a long time to clean the inner wall of the screen cylinder 13, effectively improving the processing efficiency of epoxy resin.

[0027] Please see Figures 1 to 3The drive mechanism includes a first motor 9. The first motor 9 is installed on the lower part of the base 1 near the middle. A first reversing gear 10 is installed on the shaft end of the first motor 9. A second reversing gear 11 is installed on the rotating shaft end of the turntable 6 corresponding to the first reversing gear 10. The tooth pitch of the drive gear 18 is equal to the tooth pitch of the ring gear 19, and the drive gear 18 meshes with the ring gear 19. When the first motor 9 is working, it drives the first reversing gear 10 to rotate. The first reversing gear 10 drives the second reversing gear 11 to rotate through meshing. The second reversing gear 11 drives the turntable 6 to rotate, thereby enabling the position of the two screen cylinders 13 to be changed. When the second motor 17 is working, it drives the drive gear 18 to rotate. The drive gear 18 drives the ring gear 19 to rotate through meshing. The ring gear 19 drives the screen cylinder 13 to rotate around the support tube 12 through a fixed connection, thereby facilitating the cleaning of the screen cylinder 13 or the centrifugal filtration of epoxy resin.

[0028] Please see Figures 1 to 3 The base 1 has symmetrical fixed rods 20 installed on the top of both sides near the turntable 6. The top of the fixed rods 20 has a positioning groove 21. The bottom of the lifting frame 8 is fixedly connected to the positioning rod 22 corresponding to the positioning groove 21. The outer diameter of the positioning rod 22 matches the inner diameter of the positioning groove 21, and the bottom of the positioning rod 22 is chamfered. When the hydraulic rod 7 drives the lifting frame 8 to fall, so that the two screen cylinders 13 enter the centrifuge tank 2 and the cleaning tank 3, the lifting frame 8 drives the positioning rod 22 into the positioning groove 21. Through the positioning structure formed by the positioning rod 22 and the positioning groove 21, the lifting frame 8 can be kept stable and prevent the lifting frame 8 from shaking when the screen cylinder 13 rotates.

[0029] Please see Figures 1 to 3 The backwashing mechanism includes a U-shaped tube 23. The U-shaped tube 23 is installed inside the cleaning tank 3. The bottom end of the U-shaped tube 23 is connected to the water inlet pipe 24. The side of the U-shaped tube 23 near the side wall of the screen cylinder 13 has spray holes 25 at equal intervals. When the screen cylinder 13 needs to be cleaned, the sealing plug 27 at the bottom of the screen cylinder 13 is opened, and then the screen cylinder 13 is allowed to enter the cleaning tank 3. The second motor 17 drives the screen cylinder 13 to rotate. At the same time, the rinsing water enters the U-shaped tube 23 through the water inlet pipe 24 and is then sprayed out through the spray holes 25 to backwash the side wall of the screen cylinder 13. The impurities attached to the inner wall of the screen cylinder 13 are discharged through the bottom drain port 26 and then discharged from the inside of the cleaning tank 3 through the drain pipe 5. The backwashing mechanism automatically cleans the inner wall of the screen cylinder 13, avoiding manual cleaning of the screen cylinder 13, improving cleaning efficiency and saving labor costs.

[0030] Working Principle: This electronic-grade epoxy resin centrifuge uses a hydraulic rod 7 to lift and lower two screen cylinders 13 via a lifting frame 8 and support pipe 12. A drive mechanism rotates the turntable 6, allowing the screen cylinders 13 to switch positions. This enables the screen cylinders 13 to enter the centrifuge tank 2 and the cleaning tank 3 respectively. This allows the epoxy resin centrifuge to separate epoxy resin from impurities during centrifugation, while the cleaning tank 3 uses a backwashing mechanism to clean the other screen cylinder 13. This avoids the need for prolonged shutdown of the epoxy resin centrifuge to clean the inner wall of the screen cylinder 13. This effectively improves the processing efficiency of epoxy resin. When the first motor 9 is working, it drives the first reversing gear 10 to rotate. The first reversing gear 10 drives the second reversing gear 11 to rotate through meshing. The second reversing gear 11 drives the turntable 6 to rotate, which in turn enables the positions of the two screen cylinders 13 to be changed. When the second motor 17 is working, it drives the drive gear 18 to rotate. The drive gear 18 drives the ring gear 19 to rotate through meshing. The ring gear 19 drives the screen cylinder 13 to rotate around the support tube 12 through a fixed connection, which facilitates the cleaning of the screen cylinder 13 or the centrifugal filtration of epoxy resin.

[0031] When the hydraulic rod 7 lowers the lifting frame 8, allowing the two screen cylinders 13 to enter the centrifuge tank 2 and the cleaning tank 3, the lifting frame 8 drives the positioning rod 22 into the positioning groove 21. The positioning structure formed by the positioning rod 22 and the positioning groove 21 ensures the stability of the lifting frame 8, preventing it from shaking when the screen cylinders 13 rotate. Before the screen cylinders 13 enter the centrifuge tank 2, the drain port 26 is sealed with a sealing plug 27. Then, the screen cylinders 13 enter the centrifuge tank 2, and the second motor 17 drives them to rotate. The sealing cover 16 is then opened, allowing the epoxy resin containing mixed impurities to enter the screen cylinders 13 through the support pipe 12 and the feed inlet 15. The rotation of the screen cylinders generates centrifugal force, causing the screen cylinders 13 to... The sieve holes separate epoxy resin from impurities. The filtered epoxy resin is discharged through the discharge pipe 4. When the sieve cylinder 13 needs to be cleaned, the sealing plug 27 at the bottom of the sieve cylinder 13 is opened, and then the sieve cylinder 13 is allowed to enter the cleaning tank 3. The second motor 17 drives the sieve cylinder 13 to rotate. At the same time, the rinsing water enters the U-shaped pipe 23 through the water inlet pipe 24 and is then sprayed out through the spray hole 25 to backwash the side wall of the sieve cylinder 13. The impurities attached to the inner wall of the sieve cylinder 13 are discharged through the bottom drain port 26 and then discharged from the inside of the cleaning tank 3 through the drain pipe 5. The backwashing mechanism automatically cleans the inner wall of the sieve cylinder 13, avoiding manual cleaning of the sieve cylinder 13, improving cleaning efficiency and saving labor costs.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
