Description

Technical Field

[0001] This utility model relates to the field of resin technology, and more specifically, to a stirred tank for the synthesis of optical resins. Background Technology

[0002] According to announcement number CN201921619113.4, a stirred tank for optical resin synthesis relates to the field of optical resin production technology. It includes a base frame and a tank body, with the tank body mounted on the base frame. A stirring shaft driven by a power component is coaxially mounted on the tank body. A stirring blade assembly located inside the tank body is mounted on the stirring shaft. The stirring shaft is slidably sealed to the top and bottom of the tank body. A threaded sleeve coaxially arranged with the stirring shaft is mounted on the base frame. A portion of the stirring shaft outside the tank body is screwed into the threaded sleeve. A mounting plate is connected to a first motor of the power component. A guide rod parallel to the stirring shaft is slidably connected to a mounting block mounted on the base frame. The end of the guide rod is fixed to the mounting plate. The drive shaft of the first motor is connected to the stirring shaft. This invention solves the technical problems of low stirring efficiency and poor quality in existing stirred tanks. This invention can achieve rotational and reciprocating lifting stirring, resulting in more comprehensive, uniform, and efficient material stirring.

[0003] In the stirred tank for resin synthesis, gas or liquid needs to be added to the stirred tank, so that the liquid inlet pipe and the gas inlet pipe will rotate with the rotation of the main shaft tube. The above structure brings great inconvenience to the connection and use of the pipes, and the gas outlet is unevenly distributed, which makes it impossible to disperse the gas into different depths of the resin in the tank when it is introduced, greatly reducing the stirring effect of the resin. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a stirred tank for optical resin synthesis. This stirred tank for optical resin synthesis, through the setting of a support base and a feeding chamber, can prevent the water supply pipe and air inlet pipe from rotating with the shaft. At the same time, the setting of a discharge nozzle greatly improves the uniformity of air and water intake, greatly improving the ease of use of the resin stirred tank. Furthermore, through the setting of a stirring rod, stirring blades, and scraper, not only can the inner wall of the tank be cleaned, but the stirring effect of the resin inside the tank can also be increased, thereby improving the working efficiency of the resin stirred tank.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A stirred tank for optical resin synthesis includes a stirred tank, one end of which is provided with a cover plate and a feeding port, and the other end of which is provided with a support leg and a discharge pipe. A support base is fixedly installed at the center of the cover plate, and a water inlet pipe and an air inlet pipe are respectively provided on both sides of the support base. One end of the water inlet pipe and the air inlet pipe is connected to a feeding chamber. A motor is fixedly installed on the top of the support base, and a rotating shaft is provided at the output end of the motor. The rotating shaft has a first guide hole inside, and the inner wall of the first guide hole is connected to a feeding hole. A stirring blade is fixedly installed at one end of the rotating shaft, and a stirring agitator is fixedly connected to the surface of the rotating shaft. The mixing rod has discharge nozzles evenly distributed on its surface. A telescopic rod is fixedly installed at one end of the mixing rod, and a scraper is fixedly connected to the other end of the telescopic rod. This mixing vessel for optical resin synthesis, through its support base and feeding chamber, prevents the water and air inlet pipes from rotating with the shaft. Simultaneously, the discharge nozzles greatly improve the uniformity of air and water intake, significantly enhancing the ease of use of the resin mixing vessel. Furthermore, the mixing rod, blades, and scraper not only clean the inner wall of the vessel but also increase the mixing effect of the resin inside, improving the working efficiency of the resin mixing vessel.

[0007] Furthermore, the feed holes are distributed in a ring with equal spacing around the center of the first guide hole. The feed holes are strip-shaped, and one end of the feed hole is connected to the feeding chamber, which facilitates the entry of high-pressure air and water in the feeding chamber into the first guide hole.

[0008] Furthermore, a one-way valve is fixedly installed on the surface of the discharge nozzle, and one end of the discharge nozzle is connected to a second guide hole. One end of the second guide hole is connected to the interior of the first guide hole, which facilitates the introduction of high-pressure air and water in the first guide hole into the discharge nozzle for discharge.

[0009] Furthermore, one end of the stirring rod is provided with an installation groove, and a sealing ring is fixedly installed on the inner wall of the installation groove. The inner wall of the sealing ring contacts and presses against the surface of the telescopic rod, ensuring the sealing of the telescopic end of the telescopic rod and preventing it from being blocked by resin, thus avoiding poor telescopic movement.

[0010] Furthermore, the surface of the stirring rod is provided with strip-shaped holes, which are evenly distributed along the length of the stirring rod to reduce the resistance of the resin when the stirring rod rotates.

[0011] Furthermore, a sealed bearing is fixedly sleeved at the center of both the cover plate and the support seat, and the inner ring of the sealed bearing is fixedly sleeved with the surface of the rotating shaft.

[0012] Furthermore, both the water inlet pipe and the air inlet pipe are equipped with one-way control valves to prevent water from entering the air inlet pipe or high-pressure air from entering the water inlet pipe.

[0013] Compared with existing technologies, the advantages of this utility model are:

Sealed bearings 22 are fixedly sleeved at the center of both the cover plate 11 and the support base 2. The inner ring of the sealed bearing 22 is fixedly sleeved with the surface of the rotating shaft 31. A water inlet pipe 23 and an air inlet pipe 24 are respectively provided on both sides of the support base 2. One-way control valves are provided on the surfaces of both the water inlet pipe 23 and the air inlet pipe 24 to prevent water from entering the air inlet pipe 24 or high-pressure air from entering the water inlet pipe 23. One end of the air inlet pipe 24 is connected to the feeding chamber 21. A motor 3 is fixedly installed on the top of the support base 2. A rotating shaft 31 is provided at the output end of the motor 3. A first guide hole 33 is provided inside the rotating shaft 31. The inner wall of the first guide hole 33 is connected to the feed hole 32. A stirring blade 34 is fixedly installed at one end of the rotating shaft 31. A stirring rod 4 is fixedly connected to the surface of the rotating shaft 31. Discharge nozzles 43 are evenly distributed on the surface of the stirring rod 4. A telescopic rod 45 is fixedly installed at the other end of the stirring rod 4. A scraper 46 is fixedly connected to the other end of the telescopic rod 45. The scraper 46 stirs the resin during resin stirring. When it is necessary to clean the inner wall of the mixing tank 1, the telescopic rod 45 extends and contacts the inner wall of the mixing tank 1 to scrape off the resin inside the tank. The entire equipment is made of titanium, glass enamel, or fluoropolymer-lined material. Iron cannot be used.

[0026] The feed holes 32 are arranged in a ring with equal spacing around the center of the first guide hole 33. The feed holes 32 are strip-shaped. One end of the feed holes 32 is connected to the feeding chamber 21, which facilitates the entry of high-pressure air and water in the feeding chamber 21 into the first guide hole 33. A one-way valve 44 is fixedly installed on the surface of the discharge nozzle 43. One end of the discharge nozzle 43 is connected to the second guide hole 42.

[0027] One end of the stirring rod 4 is provided with an installation groove, and a sealing ring 47 is fixedly installed on the inner wall of the installation groove. The inner wall of the sealing ring 47 contacts and presses against the surface of the telescopic rod 45, ensuring the sealing of the telescopic end of the telescopic rod 45 and preventing it from being blocked by resin and causing poor telescopic movement. The surface of the stirring rod 4 is provided with strip-shaped holes 41, which are evenly distributed along the length of the stirring rod 4, which can reduce the resistance of the resin when the stirring rod 4 rotates.

[0028] When using this stirred tank for optical resin synthesis, the motor 3 is started first. The motor 3 drives the rotating shaft 31 to rotate, which in turn drives the stirring blades 34, stirring rods 4, and scraper 46 to rotate. Then, the resin raw material is added to the stirred tank 1 through the feeding port for stirring. At the same time, water and high-pressure air are added to the feeding chamber 21 through the water supply pipe 23 and the air inlet pipe 24. Then, the air and water enter the rotating shaft 31 and are then transported to the stirring rods 4 at different heights. Finally, they are discharged through the discharge nozzle 43, so that the air and water enter the resin raw material at different depths, thereby increasing the uniformity of water and high-pressure gas addition and facilitating stirring.
