Description

Technical Field

[0001] The present application relates to the technical field of epoxy resin production, and in particular to an epoxy resin production device. Background Art

[0002] Epoxy resin is a polymer material that is widely used in coatings, adhesives, composite materials and other fields. In the production process of epoxy resin, various raw materials are usually fed into the production stirring device for mixing reaction.

[0003] However, after the raw materials are stirred and reacted and discharged from the device, a large amount of reactants often remain on the inner wall of the device. Due to the viscosity of the reactants themselves, the reactants on the inner wall of the device take a long time to be discharged and some of them adhere to the inner wall of the device and are difficult to be discharged, making it difficult to clean the device later. Utility Model Content

[0004] In order to improve the convenience of cleaning the production equipment, the present application provides an epoxy resin production equipment.

[0005] The present application provides an epoxy resin production device, which adopts the following technical solution:

[0007] The stirring mechanism includes a power assembly, a mounting cylinder, a stirring blade, a scraping blade and an adjusting member; the power assembly is mounted on the tank cover; the mounting cylinder is coaxially located in the reaction tank and connected to the power assembly, and is driven by the power assembly to move up and down and rotate in the reaction tank at the same time; the stirring blade is connected to the mounting cylinder, and the scraping blade moves in the stirring blade along the direction of approaching or moving away from the inner wall of the reaction tank; the adjusting member is mounted on the mounting cylinder, and is used to adjust the distance between the scraping blade and the inner wall of the reaction tank, so that the scraping blade can move to contact and separate from the inner wall of the reaction tank.

[0008] By adopting the above technical solution, after the reactants are unloaded, the position of the scraper blade is adjusted to be against the inner wall of the reaction tank, so that when the power component drives the mounting cylinder to move, the scraper blade can synchronously scrape the inner wall of the reaction tank, thereby reducing the residue of reactants on the inner wall of the device and improving the convenience of cleaning the production device.

[0009] Optionally, the adjusting member includes a rotating handle, an adjusting rod and an abutment tube connected in sequence from bottom to top; the adjusting rod is threadedly moved up and down on the mounting tube; the abutment tube is located in the mounting tube, and the outer diameter of the abutment tube gradually increases upward; the scraper blade is connected to a linkage seat that extends into the mounting tube and is magnetically attracted to the outer wall of the abutment tube.

[0010] By adopting the above technical solution, the rotating handle is rotated to drive the adjusting rod to move threadedly on the mounting tube, thereby driving the abutment tube to move up and down relative to the mounting tube, so as to adjust the position of the abutment tube and the linkage seat, thereby pushing the scraper blade to move relative to the stirring blade to adjust the position of the scraper blade.

[0011] Optionally, the stirring blade is connected to an elastic member which is also connected to the scraping blade, and the elastic member provides elastic force to the scraping blade to move toward the mounting cylinder.

[0012] By adopting the above technical solution, the stability of the scraping blade in resetting toward the mounting barrel is further enhanced by the elastic member.

[0013] Optionally, the power assembly includes a rotating seat, a telescopic power source and a rotating member; the rotating seat is coaxially rotatably connected to the tank cover; the telescopic power source seat is connected to the rotating seat, and the telescopic end of the telescopic power source is connected to the mounting tube; the rotating member is installed on the tank cover to drive the rotating seat to rotate.

[0014] By adopting the above technical solution, the rotating seat is used as the installation base to cooperate with the telescopic power source and the rotating member to achieve the up and down movement and rotation of the installation cylinder.

[0015] Optionally, a flexible enclosure is connected between the rotating seat and the mounting cylinder, and the flexible enclosure isolates the telescopic end of the telescopic power source from the inner cavity of the reaction tank.

[0016] By adopting the above technical solution, the flexible enclosure isolates the telescopic end of the telescopic power source from the inner cavity of the reaction tank, so that the reactants in the reaction tank are not easily affected by the telescopic movement of the telescopic power source.

[0017] Optionally, the flexible enclosure is detachably connected to the rotating seat and the mounting cylinder.

[0018] By adopting the above technical solution, the detachable connection design between the flexible enclosure, the rotating seat and the mounting cylinder facilitates cleaning or replacement when necessary, thereby maintaining the cleanliness and hygiene of the device.

[0023] By adopting this technical solution, the power element achieves vertical expansion and contraction and compression of the tank lid, facilitating quick opening and closing of the lid when needed for operations such as adding materials and cleaning. Furthermore, the vertical expansion and contraction function of the power element also ensures a tight seal between the lid and the reactor.

[0025] 1. By adjusting the position of the scraper blade, the scraper blade can be adjusted to separate from the inner wall of the reaction tank during stirring to improve the smoothness of the stirring blade movement.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application discloses an epoxy resin production device. Figure 1 The epoxy resin production device includes a reaction tank 1, a tank cover 2, and a stirring mechanism. The reaction tank 1 is supported by a bracket, the tank cover 2 is mounted on the reaction tank 1, and the stirring mechanism is mounted on the tank cover 2 and extends into the reaction tank 1 to stir the raw materials in the reaction tank 1.

[0035] Among them, the reaction tank 1 is in the shape of a hollow cylinder with a discharge port 3 at the bottom. The bottom of the reaction tank 1 gradually narrows towards the discharge port 3 to guide the discharge of the reactants, and the reaction tank 1 is detachably connected to a closure cover at the discharge port 3 to open and close the discharge port 3.

[0036] Reference Figure 1 and Figure 2 The tank cover 2 is a dome-shaped cover that fits over the reactor tank 1. Its inner diameter matches the outer diameter of the reactor tank 1, and it has connecting ears 13 on its periphery. Power members 12 are mounted on opposite sides of the reactor tank 1's outer wall. Power members 12 are pneumatic cylinders, with their bases fixedly connected to the reactor tank 1's outer wall. The telescopic ends of power members 12 are detachably bolted to the connecting ears 13, with the telescopic ends of power members 12 positioned vertically and facing upward.

[0037] When the power member 12's retracted end is retracted, it drives the lid 2 downward to close over the top of the reactor 1. When the power member 12's retracted end is extended, it drives the lid 2 upward away from the top of the reactor 1, opening the top of the reactor 1. The bolts connecting the power member 12 to the lid 2 are then removed, allowing the lid 2 and the stirring mechanism to be completely removed from the reactor 1 for cleaning, replacement, and other operations. Furthermore, the reactor 1 can be fed through an inlet (not shown) provided on the lid 2 and connected to a pipeline. Alternatively, the reactor 1 can be unloaded while the top of the reactor 1 is open.

[0038] Reference Figure 1 and Figure 2The stirring mechanism includes a power assembly 4, a mounting barrel 5, a stirring blade 6, a scraping blade 7, and an adjusting member 8. The power assembly 4 is mounted on the tank cover 2. The mounting barrel 5 is cylindrical and connected to the power assembly 4. When the tank cover 2 covers the reaction tank 1, the mounting barrel 5 is located in the reaction tank 1 and is coaxial with the reaction tank 1. The power assembly 4 can drive the mounting barrel 5 to move up and down in the reaction tank 1 while rotating.

[0039] The stirring blade 6 is in the shape of a square sheet. One end of the stirring blade 6 is fixed to the outer wall of the mounting barrel 5 so that the blade surface of the stirring blade 6 extends along the vertical plane. A plurality of stirring blades 6 are evenly spaced and fixed along the outer circumference of the mounting barrel 5. In the embodiment of the present application, there are four stirring blades 6. In other embodiments, there may be two, three, or five stirring blades 6. There is a certain distance between the end of the stirring blade 6 away from the mounting barrel 5 and the inner wall of the reaction tank 1.

[0040] The scraper blades 7 are also square-shaped, corresponding one to one with the stirring blades 6. They slide radially along the mounting barrel 5 within the corresponding stirring blades 6, with the blade surface of the scraper blade 7 coinciding with the extension direction of the blade surface of the corresponding stirring blade 6. The end of the scraper blade 7 away from the mounting barrel 5 extends beyond the stirring blade 6 and has an arcuate surface. The arc opening of the scraper blade faces the mounting barrel 5, and the outer diameter is consistent with the inner diameter of the reaction tank 1. When the scraper blade is able to move away from the mounting barrel 5, the arc surface can adhere to the inner wall of the reaction tank 1.

[0041] Reference Figure 2 and Figure 3 The adjusting member 8 is mounted on the mounting tube 5 and comprises a rotating handle 81, an adjusting rod 82, and an abutting tube 83, which are fixedly connected in sequence from bottom to top. Specifically, the mounting tube 5 is hollow, and the abutting tube 83 is located within the mounting tube 5. The abutting tube 83 has a conical shape with an outer diameter gradually decreasing downward, and the abutting tube 83 is coaxial with the mounting tube 5. The adjusting rod 82 is screw-shaped and coaxial with the abutting tube 83. The adjusting rod 82 is threadedly connected to the bottom of the mounting tube 5 up and down. The bottom end of the adjusting rod 82 extends out of the mounting tube 5 and is connected to the rotating handle 81. By rotating the rotating handle 81, the adjusting rod 82 is threadedly moved up and down, thereby adjusting the height of the abutting tube 83 in the mounting tube 5.

[0042] A rod-shaped linkage seat 9 is fixed to the end of the scraper blade 7 closest to the mounting barrel 5, with the length of the linkage seat 9 parallel to the radial direction of the mounting barrel 5. The end of the linkage seat 9, which is away from the scraper blade 7, extends into the mounting barrel 5 and is magnetically attracted to the outer wall of the abutment barrel 83. By adjusting the height of the abutment barrel 83 in the mounting barrel 5, the distance that the scraper blade 7 extends from the stirring blade 6 can be adjusted. The linkage seats 9 on all scraper blades 7 abut against the same abutment barrel 83 and have the same horizontal position.

[0043] Reference Figure 1 and Figure 3When the raw materials need to be stirred, the abutment tube 83 is adjusted upward so that the linkage seat 9 abuts against the bottom of the outer periphery of the abutment tube 83. At this time, there is space between the end of the scraper blade 7 away from the mounting tube 5 and the inner wall of the reaction tank 1, so that the power component 4 can drive the stirring blade 6 to move up and down and rotate in the reaction tank 1 at a faster speed, and the scraper blade 7 is not easy to interfere with the reaction tank 1 and affect the movement of the stirring blade 6.

[0044] After the raw materials are stirred and discharged, the abutment tube 83 is adjusted downward so that the linkage seat 9 abuts against the top of the outer periphery of the abutment tube 83, and the end of the scraper blade 7 away from the mounting tube 5 abuts against the inner wall of the reaction tank 1. When the power component 4 drives the stirring blade 6 to move up and down and rotate in the reaction tank 1 at a slower speed, the scraper blade 7 can scrape off the residual reactants on the inner wall of the reaction tank 1, thereby improving the convenience of cleaning the reaction tank 1 later.

[0045] Reference Figure 3 Furthermore, an elastic member 10 is installed in the stirring blade 6. The elastic member 10 is a spring. One end of the elastic member 10 is connected to the inner wall of the stirring blade 6, and the other end of the elastic member 10 is connected to the end of the scraper blade 7 close to the mounting cylinder 5. The elastic force of the elastic member 10 always gives the scraper blade 7 a tendency to move toward the mounting cylinder 5, thereby assisting the abutment cylinder 83 in moving upward and driving the scraper blade 7 to return to the position close to the mounting cylinder 5.

[0046] Reference Figure 4 and Figure 5 Furthermore, the power assembly 4 that drives the mounting cylinder 5 to move includes a rotating base 41, a telescopic power source 42, and a rotating member 43. The rotating base 41 is disc-shaped and is rotatably connected to the center of the tank cover 2, and the bottom end of the rotating base 41 extends into the cavity of the tank cover 2, and the top end of the rotating base 41 extends upward from the top of the tank cover 2.

[0047] The telescopic power source 42 is a multi-stage electric telescopic rod. Its base is fixedly connected to the top of the rotating base 41. The telescopic end of the telescopic power source 42 passes through the rotating base 41 and is coaxially connected to the mounting tube 5. Bolts connect the telescopic end to the rotating base 41 to facilitate assembly and disassembly. When the telescopic end of the telescopic power source 42 is extended, it drives the mounting tube 5 and the stirring blades 6 to the bottom of the reactor 1. When the telescopic end of the telescopic power source 42 is retracted, it drives the mounting tube 5 and the stirring blades 6 to the top of the reactor 1.

[0048] The rotating member 43 includes a driving gear 431, a driven gear 432, and a rotating motor 433. The driving gear 431 is rotatably connected to the top of the tank cover 2, and the driven gear 432 is coaxially fixedly mounted on the top of the rotating base 41, and the driven gear 432 meshes with the driving gear 431. The rotating motor 433 is mounted on the top of the tank cover 2 and can rotate forward and reverse. The output end of the rotating motor 433 is coaxially fixed to the driving gear 431, so that the rotating motor 433 drives the driven gear 432 to rotate, thereby driving the driving gear 431 and the rotating base 41 to rotate, thereby driving the telescopic power source 42, the mounting barrel 5, and the stirring blade 6 to rotate around the axis of the mounting barrel 5.

[0049] When the position of the abutment seat needs to be adjusted, the tank cover 2 is first driven to move upward and away from the reaction tank 1 by the power member 12, and then the telescopic end of the telescopic power source 42 is retracted to move the mounting tube 5 upward and away from the reaction tank 1, so that the rotating handle 81 is exposed, so that the staff can move and adjust the rotating handle 81.

[0050] Reference Figure 2 and Figure 4 Furthermore, the telescopic end of the telescopic power source 42 is detachably connected to the mounting tube 5 via bolts, and a flexible enclosure 11 is detachably connected between the rotating base 41 and the mounting tube 5. The flexible enclosure 11 can be made of flexible fabric or accordion material. The flexible enclosure 11 is cylindrical with a hollow interior, and has rigid connecting rings 14 at both opposing ends of the flexible enclosure 11. The connecting rings 14 at both ends of the flexible enclosure 11 are detachably connected to the opposite side of the rotating base 41 from the mounting tube 5 via bolts. The flexible enclosure 11 encloses the telescopic end of the telescopic power source 42 to isolate the telescopic end of the telescopic power source 42 from the reactants in the reaction tank 1.

[0051] After the stirring is completed, the flexible enclosure 11 can be replaced through the detachable connection between the telescopic power source 42 and the mounting cylinder 5 , and the detachable connection between the flexible enclosure 11 and the mounting cylinder 5 and the rotating seat 41 .

[0052] The working principle of the epoxy resin production device of the embodiment of the present application is as follows: before stirring the raw materials in the reaction tank 1, the abutment cylinder 83 is first adjusted to the bottom to abut against the linkage seat 9, so that a gap exists between the scraper blade 7 and the inner wall of the reaction tank 1, and then the raw materials are stirred. After the raw materials are stirred and discharged, the tank cover 2 is moved upward and the position of the abutment cylinder 83 is adjusted so that the abutment cylinder 83 moves to the top to abut against the linkage seat 9, so that the scraper blade 7 enters the reaction tank 1 and abuts against the inner wall of the reaction tank 1. The power component 4 drives the mounting cylinder 5 to move up and down and rotate, thereby driving the scraper blade 7 to scrape off the reactants adhering to the inner wall of the reaction tank 1.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
