Description

Technical Field

[0001] This utility model relates to the technical field of degassing devices, specifically an epoxy resin degassing device. Background Technology

[0002] Epoxy resin is a high molecular weight polymer, referring to a class of polymers containing two or more epoxy groups in their molecules. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical reactivity of epoxy groups, many compounds containing active hydrogen can react with it to open the ring, thereby curing and cross-linking to form a network structure. Therefore, it is a thermosetting polymer synthetic material.

[0003] In traditional epoxy resin degassing processes, epoxy resin inevitably adheres to the inner wall of the degassing device's tank. With prolonged use, this residual epoxy resin gradually accumulates on the tank's inner wall, affecting not only the tank's effective volume and reducing degassing efficiency, but also potentially contaminating new epoxy resin in subsequent production processes, thus polluting product quality and impacting its performance and stability. Therefore, this paper proposes an epoxy resin degassing device. Utility Model Content

[0004] The purpose of this invention is to provide an epoxy resin degassing device to solve the problems mentioned in the background art.

[0006] A vacuum pump is provided on one side of the tank, a first motor is fixed on the top of the cover plate, a rotating shaft is fixed on the output shaft end of the first motor, and a stirring blade is fixed on the outside of the rotating shaft.

[0007] A cleaning component for cleaning the tank is provided on one side of the tank body;

[0008] The cleaning assembly includes a second motor, a lead screw is fixed to the output shaft end of the second motor, a horizontal plate is threaded to the outside of the lead screw, support rods are fixed to both sides of the bottom of the horizontal plate, and a first connecting block located under the cover plate is fixed to the bottom of the support rods.

[0009] A second connecting block is bolted to one side of the first connecting block, and a scraper is fixed to one side of the bottom of the second connecting block.

[0010] Preferably, the cover plate has a first sealing ring bonded to its bottom, and the outer side of the rotating shaft is rotatably connected to the center of the cover plate via a sealed bearing.

[0011] Preferably, the cover plate has a second sealing ring that is slidably connected to the outside of the support rod, the scraper is slidably connected to the inner wall of the tank, and the second motor is fixed to the top of the cover plate.

[0012] Preferably, the cover plate has two sliding pillars fixed to its top, the outer side of each sliding pillar extends through one side of the horizontal plate, and a second limiting block is fixed to the top of each sliding pillar.

[0013] Preferably, the top of the lead screw is fixed with a first limiting block, and two lead screw protective covers are sleeved on the outside of the lead screw.

[0014] Preferably, the vacuum pump inlet is connected to an air pipe, one end of which is fixed to one side of the cover plate. When the bottom of the cover plate is connected to the top of the tank, the air pipe is connected to the inside of the tank.

[0015] Preferably, the tank body is fixed to one side of a mounting bracket, and a hydraulic cylinder is fixed to the top side of the mounting bracket. The push rod end of the hydraulic cylinder is fixed to one side of the cover plate.

[0016] Preferably, the bottom of the tank is fixedly connected to a discharge pipe, and a valve is installed on the discharge pipe.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0018] 1. By using a hydraulic cylinder to tightly connect the cover plate to the top of the tank, and in conjunction with the first sealing ring at the bottom of the cover plate, gas leakage can be effectively prevented, ensuring a stable closed space inside the tank. Simultaneously, a vacuum pump, connected to the tank interior via a gas pipe, can smoothly extract air from the tank. A first motor drives the rotating shaft and stirring blades to rotate inside the tank. The stirring action of the blades breaks the stable state inside the epoxy resin, making it easier for bubbles to rise to the surface. Furthermore, combined with the vacuum environment, the rate at which bubbles rise and escape is further accelerated, improving the degassing efficiency of the epoxy resin.

[0019] Second, the second motor of the cleaning component drives the lead screw to rotate, which in turn moves the horizontal plate up and down along the slide column, thereby causing the scraper to slide up and down on the inner wall of the tank to scrape off the epoxy resin remaining on the inner wall of the tank, ensuring the cleanliness of the inner wall of the tank and avoiding the residue from causing pollution to subsequent production or affecting product quality; the scraper is connected to the second connecting block by bolts, which makes it easy to replace the scraper.

[0029] Example

[0030] Please see Figure 1-5 This utility model provides a technical solution: an epoxy resin degassing device, including a tank 1, a cover plate 6 on the top of the tank 1, and epoxy resin to be filled inside the tank 1; a vacuum pump 9 is provided on one side of the tank 1, a first motor 3 is fixed to the top of the cover plate 6, a rotating shaft 11 is fixed to the output shaft end of the first motor 3, and a stirring blade 10 is fixed to the outside of the rotating shaft 11; the first motor 3 drives the rotating shaft 11 to drive the stirring blade 10 to rotate at high speed, forming a centrifugal vortex field inside the tank 1. During the rotation, the resin generates shear force, forcibly separating the internal bubbles to the liquid surface;

[0031] A fixing frame 8 is fixed on one side of the tank body 1, and a hydraulic cylinder 2 is fixed on the top side of the fixing frame 8. The hydraulic cylinder 2 is connected to a hydraulic station, which provides the power source for the hydraulic cylinder 2. The push rod end of the hydraulic cylinder 2 is fixed to one side of the cover plate 6. The hydraulic cylinder 2 drives the cover plate 6 to open and close. Precise positioning is achieved through the fixing frame 8, and a reliable seal is formed with the first sealing ring. A discharge pipe 12 is fixedly connected to the bottom of the tank body 1, and a valve is installed on the discharge pipe 12.

[0032] A cleaning assembly 5 for cleaning the tank 1 is provided on one side; the cleaning assembly 5 includes a second motor 51, a lead screw 55 is fixed to the output shaft end of the second motor 51, a horizontal plate 56 is threaded to the outside of the lead screw 55, support rods 53 are fixed on both sides of the bottom of the horizontal plate 56, and a first connecting block 59 located under the cover plate 6 is fixed to the bottom of the support rods 53; the second motor 51 of the cleaning assembly 5 drives the lead screw 55 to rotate, thereby causing the horizontal plate 56 to move vertically along the slide column 52;

[0033] A second connecting block 510 is bolted to one side of the first connecting block 59. A scraper 58 is fixed to one side of the bottom of the second connecting block 510. The scraper 58 can be made of stainless steel. The scraper 58 is connected to the support rod 53 through the second connecting block 510. The detachable bolt connection facilitates the replacement of worn scraper 58. The scraper 58 maintains a small gap with the inner wall of the tank 1, which is about 0.1-0.5mm. Adhesive resin is removed by sliding contact to prevent curing residue from affecting the quality of subsequent batches. When cleaning is not required, the scraper 58 is located at the top of the tank 1.

[0034] A first sealing ring is bonded to the bottom of the cover plate 6. The first sealing ring and the sealing bearing ensure the airtightness of the connection between the cover plate 6 and maintain the vacuum. The outer side of the rotating shaft 11 is rotatably connected to the center of the cover plate 6 through the sealing bearing. A second sealing ring is fixedly embedded in the inner wall of the cover plate 6 and slidably connected to the outer side of the support rod 53. The second sealing ring provides dynamic sealing when the support rod 53 moves, maintaining a clean environment inside the tank 1. The outer side of the scraper 58 is slidably connected to the inner wall of the tank 1. The second motor 51 is fixed to the top of the cover plate 6.

[0035] Two sliding columns 52 are fixed to the top of the cover plate 6. The outer side of the sliding column 52 moves through one side of the horizontal plate 56. A second limiting block 57 is fixed to the top of the sliding column 52. A first limiting block 54 is fixed to the top of the lead screw 55. The first limiting block 54 and the second limiting block 57 are fixed to the top and bottom of the lead screw 55, respectively, to limit the movement range of the horizontal plate 56 and prevent it from exceeding the effective stroke, which would cause damage to the equipment. Two lead screw protective covers are sleeved on the outer side of the lead screw 55. The lead screw protective covers sleeved on the outer side of the lead screw 55 play a protective role and prevent impurities from entering the threaded connection between the lead screw 55 and the horizontal plate 56, which would affect the normal operation of the equipment.

[0036] The vacuum pump 9 has an air inlet connected to an air pipe 7. One end of the air pipe 7 is fixed to one side of the cover plate 6. When the bottom of the cover plate 6 is connected to the top of the tank 1, the air pipe 7 is connected to the inside of the tank 1. The vacuum pump 9 continuously draws air from the tank 1 through the air pipe 7 to form a negative pressure environment. The negative pressure causes the residual bubbles in the resin to expand in volume, reducing the internal pressure of the bubbles. Combined with the centrifugal force generated by stirring, the gas and liquid phases are rapidly separated.

[0037] Working principle: The push rod of hydraulic cylinder 2 pushes the cover plate 6 to rise, allowing the epoxy resin to be degassed to be loaded into the tank 1. The push rod of hydraulic cylinder 2 pushes the cover plate 6 to tightly connect it to the top of the tank 1, ensuring that a closed space is formed inside the tank 1. At this time, the first sealing ring at the bottom of the cover plate 6 plays a sealing role to prevent gas leakage. Vacuum pump 9 is connected to the inside of the tank 1 through air pipe 7. When vacuum pump 9 is started, the air inside the tank 1 is extracted to form a vacuum environment, which helps the air bubbles in the epoxy resin to escape.

[0038] Start the first motor 3, whose output shaft drives the rotating shaft 11 to rotate, which in turn drives the stirring blade 10 to rotate inside the tank 1. The rotation of the stirring blade 10 helps the bubbles in the epoxy resin to rise to the liquid surface faster and be discharged from the tank 1 through the vacuum environment, thus achieving the purpose of degassing.

[0039] After degassing is completed, epoxy resin is discharged through discharge pipe 12. If epoxy resin or other impurities remain on the inner wall of tank 1, cleaning component 5 can be activated for cleaning. During cleaning, cover plate 6 must be closed. The second motor 51 in cleaning component 5 is activated, and its output shaft drives lead screw 55 to rotate. Since the horizontal plate 56 is threadedly connected to lead screw 55, and the horizontal plate 56 is restricted to moving up and down by sliding column 52 on both sides, the rotation of lead screw 55 will drive the horizontal plate 56 to move up and down along sliding column 52.

[0040] The movement of the horizontal plate 56 drives the first connecting block 59 and the second connecting block 510 to move up and down via the support rod 53, which in turn drives the scraper 58 to slide up and down on the inner wall of the tank 1. The outer side of the scraper 58 contacts the inner wall of the tank 1, which can effectively scrape off residual epoxy resin; the scraper 58 and the second connecting block 510 are connected by bolts, which is convenient for disassembly and replacement to adapt to different cleaning needs.

[0041] After degassing and cleaning, open the valve on the discharge pipe 12 to discharge the treated epoxy resin from the bottom of the tank 1 for subsequent processing or use.

[0042] In summary, by using hydraulic cylinder 2 to push cover plate 6 to tightly connect to the top of tank 1, and with the first sealing ring at the bottom of cover plate 6, gas leakage can be effectively prevented, ensuring a stable closed space inside tank 1. Simultaneously, vacuum pump 9, connected to the inside of tank 1 via air pipe 7, can smoothly extract air from tank 1. First motor 3 drives rotating shaft 11 and stirring blade 10 to rotate inside tank 1. The stirring action of stirring blade 10 breaks the stable state inside the epoxy resin, making it easier for bubbles to rise to the liquid surface. Furthermore, combined with the vacuum environment, the speed at which bubbles rise and escape is further accelerated, improving the degassing efficiency of the epoxy resin.

[0043] The second motor 51 of the cleaning component 5 drives the lead screw 55 to rotate, which in turn drives the horizontal plate 56 to move up and down along the slide column 52. This causes the scraper 58 to slide up and down on the inner wall of the tank 1, scraping away the epoxy resin residue on the inner wall of the tank 1, ensuring the cleanliness of the inner wall of the tank 1, and preventing residue from contaminating subsequent production or affecting product quality. The scraper 58 is connected to the second connecting block 510 by bolts, which makes it easy to replace the scraper 58.
