Description

Technical Field

[0001] The invention relates to the technical field of optical resin production, in particular to an optical resin preparation device. Background Art

[0002] Optical resin is an organic polymer resin material with outstanding processing and optical properties. It has shown wide application potential in the field of optics. Its preparation method is a complex and delicate process, which usually covers multiple rigorous steps such as raw material preparation, precise mixing, chemical reaction and final curing. Among them, the mixing reaction of raw materials is undoubtedly the most critical link. In order to achieve this step, professional reactor equipment is needed to fully stir and dissolve various raw materials at a specific temperature to ensure that the resin matrix and the solvent can be perfectly integrated, laying a solid foundation for the subsequent curing process.

[0003] For example, the patent with the patent authorization announcement number CN210729534U discloses a stirring kettle for optical resin synthesis, including a base frame and a kettle body, the kettle body is mounted on the base frame, the kettle body is coaxially mounted with a stirring shaft driven to rotate by a power assembly, the stirring shaft is mounted with a stirring blade assembly located in the kettle body, the stirring shaft is slidably and sealedly connected to the top and bottom of the kettle body, the base frame is mounted with a threaded sleeve coaxially arranged with the stirring shaft, the part of the shaft section of the stirring shaft outside the kettle body is screwed into the threaded sleeve, the first motor of the power assembly is connected with a mounting plate, the mounting block mounted on the base frame is slidably connected with a guide rod parallel to the stirring shaft, the end of the guide rod is fixed to the mounting plate, and the driving shaft of the first motor is connected to the stirring shaft. The utility model solves the technical problems of low stirring efficiency and poor quality of stirring kettles in the prior art, and the stirring kettle used for optical resin synthesis can realize rotation, reciprocating lifting and stirring, and the material stirring is more comprehensive, uniform and efficient.

[0004] The reactor in the above patent still has certain defects: Although current reactors are all equipped with jackets for temperature control, the volumes of these jackets are fixed, which directly leads to the limitation of the volume of heating or cooling medium that can be accommodated therein. Due to the limitation of the volume of the medium, the temperature change rate of the medium is also restricted accordingly, so that the reactor takes a longer time to reach the target temperature during the heating or cooling process. In addition, the fixed jacket volume also limits the flexibility of the reactor in handling chemical reactions of different scales, making it difficult to meet the needs of reactions of different scales. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an optical resin preparation device, which not only reduces the waste of heat exchange medium, but also makes the heat exchange efficiency easier to control.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an optical resin preparation device, comprising a reactor body, a stirring mechanism and a manhole mechanism are installed on the top of the reactor body, a feeding pipe is fixedly connected to one side of the upper end of the reactor body, and a unloading pipe is fixedly connected to the bottom of the reactor body, a jacket shell is fixedly connected to the lower end of the outside of the reactor body, a top plate is slidably connected to the inside of the jacket shell, a flexible interlayer is fixedly connected to the bottom of the top plate, a closed plate is fixedly connected to the lower end of the flexible interlayer, the outer side of the closed plate is fixedly connected to the inner wall of the lower end of the jacket shell, a plurality of groups of lifting components arranged equidistantly are installed inside the jacket shell, a lower end pipe is fixedly connected to the lower end of the jacket shell, the lower end pipe is located below the closed plate, the lower end pipe is connected to the inside of the jacket shell, an upper end pipe is fixedly connected to the upper end of one side of the flexible interlayer, the upper end pipe is fixedly connected to the top plate, a gas connecting pipe connected to the inside of the jacket shell is fixedly connected to the lower end of the jacket shell, and the gas connecting pipe is located above the closed plate.

[0007] Furthermore, the lifting assembly includes an upper fixing frame, a lower fixing frame, a screw rod and a sprocket. The upper fixing frame is located at the top of the top plate, and the lower fixing frame is located at the bottom of the top plate. The upper fixing frame and the lower fixing frame are both fixedly connected to the jacket shell. The upper and lower ends of the screw rod are rotatably connected to the upper fixing frame and the lower fixing frame respectively. The top plate is threadedly connected to the screw rod, and the sprocket is fixedly connected to the top of the screw rod. The outer sleeves of the multiple sprockets are provided with chains meshing therewith. A motor is fixedly connected to the top of the jacket shell, and the output end of the motor is fixedly connected to one of the sprockets.

[0008] Furthermore, a clearance groove matching the upper end pipe is opened on one side of the jacket shell, and slots are opened on both sides and the lower end of the clearance groove. The internal sliding rod of the slot is connected to a protective plate matching it, and the upper end of the protective plate is fixed to the top plate.

[0009] Furthermore, a reinforcing block is fixedly connected to the outside of one end of the upper end pipe close to the protective plate, the reinforcing block matches the clearance groove, and the reinforcing block is slidably connected to the clearance groove.

[0010] Furthermore, a support plate is fixedly connected to the upper end of the inner wall of the jacket shell, a positioning plate is fixedly connected to the lower end of the inner wall of the jacket shell, the positioning plate is in a U-shape, and the outer wall of the lower end of the flexible interlayer is fixedly connected to the positioning plate.

[0011] Furthermore, a slide groove is provided on the side wall of the support plate, and a plurality of groups of sliders are fixedly connected to the outer wall of the flexible interlayer, the number of the sliders matches the number of the support plates, the end of the slider away from the flexible interlayer is located inside the slide groove, and the slider is slidably connected to the support plate.

[0012] Furthermore, an elastic sealing layer is fixedly connected to a side of the top plate close to the jacket shell, and a side of the elastic sealing layer away from the top plate abuts against an inner wall of the jacket shell and a side wall of the support plate.

[0013] Furthermore, an elastic scraper is fixedly connected to the inner side of the bottom of the top plate, the cross section of the elastic scraper is conical, and the side wall of the elastic scraper abuts against the outer wall of the reactor body.

[0014] Furthermore, a guide plate is fixedly connected to the bottom of the inner side of the jacket shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. After the raw materials of the optical resin are injected into the reactor body, the top plate can be moved according to the amount of the raw materials in the reactor body, thereby changing the size of the space between the flexible interlayer and the reactor body (the space is the space through which the heat exchange medium flows), which can reduce the probability of heat exchange medium being wasted and make the heat exchange efficiency easier to control.

[0016] 2. In this optical resin preparation device, since the heat exchange medium is in the space between the flexible interlayer and the reactor body, the heat of the heat exchange medium is not easily transferred to the jacket shell. This can not only improve the heat exchange efficiency, but also prevent the jacket shell from being affected by the heat exchange medium and becoming overheated or overcooled, thereby causing harm to the operator who touches the jacket shell.

[0017] 3. In the optical resin preparation device, during the movement of the top plate, the outer wall of the reactor body can be scraped by an elastic scraper to prevent impurities such as scale from adhering to the outer wall of the reactor body, which would reduce the heat exchange efficiency.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 14 , an optical resin preparation device, comprising a reactor body 1, a stirring mechanism 25 and a manhole mechanism 26 are installed on the top of the reactor body 1, a feeding pipe 28 is fixedly connected to one side of the upper end of the reactor body 1, a discharge pipe 27 is fixedly connected to the bottom of the reactor body 1, a jacket shell 2 is fixedly connected to the lower end of the outside of the reactor body 1, a top plate 9 is slidably connected to the inside of the jacket shell 2, a flexible interlayer 7 is fixedly connected to the bottom of the top plate 9, a sealing plate 5 is fixedly connected to the lower end of the flexible interlayer 7, and the outer side of the sealing plate 5 is connected to the outer side of the sealing plate 5. The inner wall of the lower end of the jacket shell 2 is fixed, and a plurality of lifting components are installed inside the jacket shell 2 at equal distances. The lower end of the jacket shell 2 is fixedly connected with a lower end pipe 8, and the lower end pipe 8 is located below the closed plate 5. The lower end pipe 8 is connected to the interior of the jacket shell 2. The upper end of one side of the flexible interlayer 7 is fixedly connected with an upper end pipe 10, and the upper end pipe 10 is fixedly connected to the top plate 9. The lower end of the jacket shell 2 is fixedly connected with a gas connecting pipe 22 connected with the interior thereof, and the gas connecting pipe 22 is located above the closed plate 5.

[0022] The optical resin preparation device of the present invention firstly adds a predetermined amount of optical resin raw material into the stirring chamber of the reactor through the material inlet and outlet, and then starts the stirring mechanism 25 for stirring through the control system of the reactor body 1. At the same time, the heating and cooling systems are adjusted according to the preset preparation program to control the temperature in the reactor body 1 so that the optical resin raw material undergoes a chemical reaction until a predetermined reaction completion degree is reached. Finally, after the reaction is completed, the prepared optical resin is discharged through the discharge pipe 27 and necessary post-processing is performed.

[0023] When controlling the temperature inside the reactor body 1, if there is less optical resin raw material inside the reactor body 1, the lifting component can be started to lower the height of the top plate 9, and the flexible interlayer 7 fixed to the top plate 9 will be compressed and folded, so that the space between the flexible interlayer 7 and the reactor body 1 (the space is the space through which the heat exchange medium flows) can be reduced, thereby reducing the use of the heat exchange medium and avoiding waste (if the flexible interlayer 7 is not compressed and folded, the height of the heat exchange medium located in the upper layer is much higher than the height of the material, and this part of the heat exchange medium cannot directly exchange heat with the material. However, these heat exchange media cannot be directly recycled after flowing out of the jacket shell 2. They also need to be cooled or heated before they can re-enter the space between the flexible interlayer 7 and the reactor body 1 for heat exchange. Therefore, after reducing the space between the flexible interlayer 7 and the reactor body 1, the use of the heat exchange medium can be reduced to avoid waste).

[0024] At the same time, if there are a lot of optical resin raw materials inside the reactor body 1, and the heat exchange efficiency cannot be effectively improved by simply adjusting the flow rate of the heat exchange medium, the lifting component can be started to increase the height of the top plate 9, and the external vacuum pump can be connected to the gas connecting pipe 22 to evacuate the air, so that the space between the flexible interlayer 7 and the jacket shell 2 is in a negative pressure state, and the flexible interlayer 7 is deformed in the direction of the jacket shell 2, thereby increasing the space between the flexible interlayer 7 and the reactor body 1, and then increasing the amount of heat exchange medium used. After the amount of heat exchange medium is increased, the heat exchange efficiency will also be improved simultaneously.

[0025] In addition, the structure of the reactor body 1 in the present invention is similar to the structure of a stirring reactor for optical resin synthesis disclosed in the patent authorization announcement number CN210729534U, so no further elaboration is made here.

[0026] As a preferred technical solution of the present invention, the lifting assembly includes an upper fixing frame 16, a lower fixing frame 17, a screw rod 18 and a sprocket 19. The upper fixing frame 16 is located at the top of the top plate 9, and the lower fixing frame 17 is located at the bottom of the top plate 9. The upper fixing frame 16 and the lower fixing frame 17 are both fixedly connected to the jacket shell 2. The upper and lower ends of the screw rod 18 are rotatably connected to the upper fixing frame 16 and the lower fixing frame 17 respectively. The top plate 9 is threadedly connected to the screw rod 18, and the sprocket 19 is fixedly connected to the top of the screw rod 18. The outer sleeves of the multiple sprockets 19 are provided with chains 20 meshing therewith. A motor 21 is fixedly connected to the top of the jacket shell 2, and the output end of the motor 21 is fixedly connected to one of the sprockets 19.

[0027] Specifically, when the motor 21 rotates, the motor 21 will drive one of the sprockets 19 to rotate, and the sprocket 19 will drive the screw rod 18 to rotate. At the same time, the sprocket 19 will also push the chain 20 meshing with it to move, and when the chain 20 moves, it will drive other sprockets 19 to rotate together, so that all the screw rods 18 will rotate. At this time, the top plate 9 threadedly connected to the screw rod 18 will rise or fall.

[0028] As a preferred technical solution of the present invention, a clearance groove 29 matching the upper end pipe 10 is opened on one side of the jacket shell 2, and slots 12 are opened on both sides and the lower end of the clearance groove 29. The internal sliding rod of the slot 12 is connected to a protective plate 11 matching it, and the upper end of the protective plate 11 is fixedly connected to the top plate 9.

[0029] Specifically, when the top plate 9 moves up and down, the top plate 9 will drive the upper pipe 10 to move together, and the opening of the clearance groove 29 makes it more convenient for the upper pipe 10 to move. At the same time, the protective plate 11 is used to protect the side of the flexible interlayer 7 close to the clearance groove 29 to prevent the flexible interlayer 7 from protruding out of the clearance groove 29 under the pressure of the heat exchange medium.

[0030] As a preferred technical solution of the present invention, a reinforcing block 24 is fixedly connected to the outside of the upper pipe 10 near the protective plate 11 , and the reinforcing block 24 matches the clearance groove 29 , and the reinforcing block 24 and the clearance groove 29 are slidably connected.

[0031] Specifically, the connection position between the upper pipe 10 and the top plate 9 and the protective plate 11 is reinforced by the reinforcing block 24 to prevent the upper pipe 10 from being separated from the top plate 9 and the protective plate 11, so that the upper pipe 10 is more stable when moving.

[0032] As a preferred technical solution of the present invention, a support plate 3 is fixedly connected to the upper end of the inner wall of the jacket shell 2, and a positioning plate 4 is fixedly connected to the lower end of the inner wall of the jacket shell 2. The positioning plate 4 is in a U-shaped shape, and the outer wall of the lower end of the flexible interlayer 7 is fixedly connected to the positioning plate 4.

[0033] Specifically, the support plate 3 and the positioning plate 4 provide support for the flexible interlayer 7, so that when negative pressure is formed between the flexible interlayer 7 and the jacket shell 2, it can prevent the outer wall of the flexible interlayer 7 from completely fitting with the inner wall of the jacket shell 2, causing the gas at the upper end of the jacket shell 2 to be blocked by the flexible interlayer 7 and difficult to be extracted, thereby making it difficult to maintain the negative pressure.

[0034] As a preferred technical solution of the present invention, a slide groove 14 is opened on the side wall of the support plate 3, and multiple groups of sliders 15 are fixedly connected to the outer wall of the flexible interlayer 7. The number of groups of sliders 15 matches the number of support plates 3. The end of the slider 15 away from the flexible interlayer 7 is located inside the slide groove 14, and the slider 15 is slidably connected to the support plate 3.

[0035] Specifically, if there is too little raw material inside the reactor body 1, even if the top plate 9 moves to the lowest position it can move, the height of the heat exchange medium is still much higher than the height of the raw material, resulting in waste. Then, gas can be injected into the gas connecting pipe 22 through an external air pump to pressurize the space between the flexible interlayer 7 and the jacket shell 2, so that the flexible interlayer 7 is deformed in the direction close to the reactor body 1. At this time, the slider 15 plays a traction role, which can avoid the flexible interlayer 7 and the reactor body 1 from being completely attached, resulting in the heat exchange medium being unable to flow.

[0036] As a preferred technical solution of the present invention, an elastic sealing layer 13 is fixedly connected to the side of the top plate 9 close to the jacket shell 2, and the side of the elastic sealing layer 13 away from the top plate 9 abuts against the inner wall of the jacket shell 2 and the side wall of the support plate 3.

[0037] Specifically, the elastic sealing layer 13 is used to seal the gap between the top plate 9 and the jacket shell 2 and the support plate 3 to prevent the space between the flexible interlayer 7 and the jacket shell 2 from being connected to the outside, thereby making it difficult to pressurize or depressurize the space between the flexible interlayer 7 and the jacket shell 2.

[0038] As a preferred technical solution of the present invention, an elastic scraper 23 is fixedly connected to the inner side of the bottom of the top plate 9. The cross section of the elastic scraper 23 is conical, and the side wall of the elastic scraper 23 abuts against the outer wall of the reactor body 1. A guide plate 6 is fixedly connected to the bottom of the inner side of the jacket shell 2.

[0039] Specifically, during the movement of the top plate 9, the outer wall of the reactor body 1 can be scraped by the elastic scraper 23 to prevent impurities such as scale from adhering to the outer wall of the reactor body 1, which would reduce the heat exchange efficiency of the heat exchange medium.

[0040] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
