Description

Technical Field

[0001] The present application relates to the technical field of epoxy resin processing, and more specifically, to an epoxy resin purification device. Background Art

[0002] High temperature resistant epoxy resin, also known as artificial resin, man-made resin, resin glue, etc., is an important type of thermosetting plastics, widely used in adhesives, coatings and other purposes. The molecular structure of high temperature resistant epoxy resin is characterized by active epoxy groups in the molecular chain. The epoxy groups can be located at the end, middle or ring structure of the molecular chain. Due to the active epoxy groups in the molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble, infusible polymers with a three-dimensional network structure. Epoxy resin has a high water content and needs to be separated. Static separation was used before, and the water separation effect was not good. It also caused a delay in the reaction time and reduced production efficiency. Therefore, the epoxy resin needs to be further purified. The current epoxy resin purification equipment generally adopts a heating plate set on the wall of the purification tank for heating, but this heating method is not uniform enough, especially the temperature near the stirring shaft and blades is low, resulting in low purification efficiency.

[0003] The document with the prior art publication number CN 219941782 U provides a high-temperature resistant epoxy resin purification device. The device heats the heating liquid through the heating wire inside the outer cylinder by arranging a stirring blade, a stirring rod, a sleeve, a bevel gear set and a driving gear. When the heating liquid is preheated, the driving gear is started, so that the bevel gear set meshing with the driving gear starts to run. After the driving gear rotates, it will drive the stirring blade to rotate, and stir the epoxy resin through the stirring blade. At the same time, the bevel gear set rotates on the outside of the rotating shaft through the sleeve, and drives the stirring rod to stir the heating liquid, so that the heat generated by the heating liquid will be evenly conducted to the inner tank, which facilitates the heating of the epoxy resin by the purification device. At the same time, the heating liquid stirred by the stirring rod will evenly transfer the heat to the epoxy resin inside the inner tank, thereby improving the working efficiency of the purification device.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the stirring blade can only rotate and stir, which leads to relatively poor tumbling intensity of the internal epoxy resin during the stirring process, thereby causing the epoxy resin to be unable to tumble violently, resulting in part of the water vapor being unable to be discharged in a timely and effective manner during the heating process, and also causing the problem of uneven heating.

[0005] Regarding the above-mentioned related technologies, the inventors believe that the stirring blade can only rotate and stir, which results in relatively poor tumbling intensity of the epoxy resin inside during the stirring process, thereby causing the epoxy resin to be unable to tumble violently, resulting in part of the water vapor being unable to be discharged in a timely and effective manner during the heating process, and also causing the problem of uneven heating.

[0006] In view of this, we propose an epoxy resin purification device. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of the present application is to provide an epoxy resin purification device, which solves the technical problems in the above-mentioned background technology and realizes that when the stirring blade rotates and stirs, it can also reciprocate up and down at the same time, thereby increasing the tumbling intensity of the internal solution, facilitating the rapid discharge of water vapor and improving the technical effect of heating uniformity.

[0009] 2. Technical solution

[0010] The technical solution of the present application provides an epoxy resin purification device, including a cylinder with a feed port, an exhaust pipe and a discharge pipe, and is characterized in that an electric heating wire is fixedly installed in the cylinder, a stirring mechanism is rotatably arranged in the cylinder, and a toggle mechanism for driving the stirring mechanism to reciprocate along the axis of the cylinder is fixedly installed on the upper end of the cylinder.

[0011] By adopting the above technical scheme, the epoxy resin solution is added into the cylinder through the feed port, and then the electric heating wire is energized to heat the solution in the cylinder. Subsequently, when the stirring mechanism is driven to move up and down by the toggle mechanism, the stirring mechanism rotates inside the cylinder under the action of the solution and stirs the epoxy resin solution, thereby achieving the goal of toggling the solution up and down while the stirring mechanism rotates, so as to increase the intensity of the tumbling of the solution, which is conducive to the rapid discharge of water vapor and improves the uniformity of heating. The water vapor is discharged through the exhaust pipe, and the purified solution is discharged through the discharge pipe.

[0013] By adopting the above technical solution, the motor is fixed on the top of the cylinder, the driving shaft passes through the positioning ring and is supported above the support plate, and the output shaft of the motor is fixed to one side of the cam. When the motor drives the cam to rotate, the cam acts on the upper end of the driving shaft, and under the elastic rebound effect generated by the extrusion and compression of the spring, the driving shaft is moved away from or close to the output shaft of the motor to realize the up and down reciprocating movement of the paddle plate and the stirring blade. The stirring blade is inclined and distributed in a ring, and then in the process of the up and down movement of the stirring blade, the stirring blade can also rotate to stir the solution, and through the shuttle-shaped structure of the paddle plate, when the paddle plate reciprocates up and down, the solution can be dispersed in a waterfall shape to increase the intensity of the tumbling of the solution.

[0015] By adopting the above technical solution, the shaft rod is fixed to the inner ring of the bearing, and the outer ring of the bearing is fixed to the upper end of the drive shaft. When the cam acts on the contact plate and the drive shaft rotates at this time, the rotation resistance of the drive shaft can be reduced through the bearing, which is beneficial to the rotation of the drive shaft and the stirring blade.

[0016] As an optional solution to the technical solution of the present application document, a plurality of guide holes adapted to the connecting rods are distributed in an annular manner on the support plate.

[0017] By adopting the above technical solution, the support plate slides up and down along the connecting rod through the guide hole. When the support plate supports the driving shaft, the stability of the spring is improved to prevent the spring from bending.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] An epoxy resin purification device includes a barrel 1 with a feed inlet 101, an exhaust pipe 102 and a discharge pipe 103, an electric heating wire 2 is fixedly installed in the barrel 1, a stirring mechanism 3 is rotatably arranged in the barrel 1, and a toggle mechanism 4 for driving the stirring mechanism 3 to reciprocate along the axis direction of the barrel 1 is fixedly installed on the upper end of the barrel 1.

[0032] Reference Figure 1-Figure 6, the epoxy resin solution is added into the cylinder 1 through the feed port 101, and then the electric heating wire 2 is energized to heat the solution in the cylinder 1, and then the stirring mechanism 3 is driven by the toggle mechanism 4 to move back and forth up and down. Under the action of the solution, the stirring mechanism 3 rotates inside the cylinder 1 to stir the epoxy resin solution, thereby realizing that the solution is toggled up and down while the stirring mechanism 3 rotates, so as to increase the tumbling intensity of the solution, which is conducive to the rapid discharge of water vapor and improves the uniformity of heating. The water vapor is discharged through the exhaust pipe 102, and the purified solution is discharged through the discharge pipe 103.

[0033] A positioning ring 104 is coaxially fixedly installed inside the cylinder 1, and the positioning ring 104 fixes a plurality of connecting rods 1061 distributed in an annular manner. A support plate 105 is fixedly installed at the lower end of the connecting rod 1061, and a spring 107 is fixedly installed on the support plate 105. A support plate 106 is fixedly installed on the upper end of the spring 107. The stirring mechanism 3 includes a driving shaft 301 and a plurality of shuttle-shaped paddles 302 fixed on the driving shaft 301 and stirring blades 303 fixed on the paddles 302 and distributed in an annular manner. The toggle mechanism 4 includes a motor 401 and a cam 402 transmission-connected to the motor 401, and the cam 402 is placed on the upper end of the driving shaft 301.

[0034] Reference Figure 1-Figure 6 The motor 401 is fixed on the top of the cylinder 1, and the driving shaft 301 passes through the positioning ring 104 and is supported on the top of the support plate 105. The output shaft of the motor 401 is fixed to one side of the cam 402. When the motor 401 drives the cam 402 to rotate, the cam 402 acts on the upper end of the driving shaft 301, and under the elastic rebound effect generated by the extrusion and compression of the spring 107, the driving shaft 301 is moved away from or close to the output shaft of the motor 401, so as to realize the up and down reciprocating movement of the paddle plate 302 and the stirring blade 303. The stirring blade 303 is inclined and annularly distributed, and then in the process of the up and down movement of the stirring blade 303, the stirring blade 303 can also rotate to paddle the solution, and through the shuttle-shaped structure of the paddle plate 302, when the paddle plate 302 reciprocates up and down, the solution can be dispersed in a waterfall shape to increase the intensity of the tumbling of the solution.

[0036] Reference Figure 2 and Figure 3 and Figure 5The shaft 3041 is fixed to the inner ring of the bearing 3011, and the outer ring of the bearing 3011 is fixed to the upper end of the drive shaft 301. When the cam 402 acts on the contact plate 304 and the drive shaft 301 rotates at this time, the bearing 3011 can reduce the rotation resistance of the drive shaft 301, which is beneficial to the rotation of the drive shaft 301 and the stirring blade 303.

[0037] A plurality of guide holes 1051 adapted to the connecting rods 1061 are distributed in an annular pattern on the support plate 105 .

[0038] Reference Figure 1 and Figure 5 and Figure 6 The support plate 105 slides up and down along the connecting rod 1061 through the guide hole 1051. When the support plate 105 supports the driving shaft 301, the stability of the spring 107 is improved to prevent the spring 107 from bending.

[0039] The electric heating wire 2 is a spiral structure.

[0040] Reference Figure 1 The spiral structure of the electric heating wire 2 and the setting of equal pitch make the internal heating of the cylinder 1 more uniform.

[0041] Working principle: the epoxy resin solution is added into the cylinder 1 through the feed port 101, the electric heating wire 2 is energized to heat the solution in the cylinder 1, the motor 401 is energized to drive the cam 402 to rotate, and when the cam 402 rotates, the drive shaft 301 is away from the output shaft of the motor 401, the spring 107 is elastically compressed, and when the cam 402 rotates, the drive shaft 301 is close to the output shaft under the elastic support of the spring 107. This is a reciprocating cycle, and in this process the solution can also drive the stirring blade 303 to rotate. The stirring blade 303 breaks up the solution during the rotation. When the paddle 302 moves back and forth up and down, the solution can be dispersed in a waterfall shape to increase the tumbling intensity of the solution.
