Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly furan resin processing, in particular to a heating and mixing device for preparing environmentally friendly furan resin. Background Art

[0002] Environmentally friendly furan resin is a general term for a class of synthetic resins containing furan rings in their molecular structure. Furan resins mainly include furfuryl alcohol resin, furfural-acetone resin and furfural-acetone-formaldehyde resin. Since they all contain furan rings in their molecular structures, they have many common characteristics in performance, such as outstanding alkali resistance, acid resistance, solvent resistance and heat resistance.

[0003] For example, an environmentally friendly furan resin preparation heating and mixing device with authorization publication number "CN211963958U" uses a motor, a heat-conducting fan, a heating wire, a heat-conducting cylinder, and a uniform cylinder to evenly disperse the furan resin in the heat-conducting cylinder, thereby heating it and reducing the heating time. However, during the rotation of the uniform cylinder of the heating and mixing device, the resin is mainly thrown toward the inner wall of the heat-conducting cylinder. Its disturbance effect on the resin interior is limited and it cannot effectively break the temperature stratification within the resin. Although the heat-conducting cylinder can transfer heat, due to its relatively closed structure, the resin has limited space for movement within the cylinder, which is not conducive to the uniform diffusion of heat in the center of the resin. Relying solely on the rotation of the heat-conducting cylinder to distribute and heat the resin on the inner wall of the cylinder, this heating and mixing method has limited heating effect on the center of the resin. At the same time, due to the viscosity of the furan resin during operation, some resin tends to remain on the inner wall of the heat-conducting cylinder and the surface of the uniform cylinder after heating and mixing. This residual resin forms a thermal insulation layer, which hinders heat transfer. Moreover, this residual resin cannot participate in the next production reaction, directly resulting in raw material loss and reducing the utilization rate of the environmentally friendly furan resin. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the uniform drum of the heating and mixing device mainly throws the resin toward the inner wall of the heat-conducting drum during rotation, and has limited disturbing effect on the inside of the resin, and cannot effectively break the temperature stratification inside the resin. The resin is distributed and heated on the inner wall of the drum only by relying on the rotation of the heat-conducting drum. This heating and mixing method has limited heating on the center of the resin and due to the viscosity of the furan resin, part of the resin is likely to remain on the inner wall of the heat-conducting drum and the surface of the uniform drum after heating and mixing are completed. These residual resins will form a heat-insulating layer, which hinders the transfer of heat. In addition, this part of the residual resin cannot participate in the next production reaction, which directly causes the loss of raw materials and reduces the utilization rate of the environmentally friendly furan resin. A heating and mixing device for preparing environmentally friendly furan resin is proposed.

[0008] Preferably, the outer wall of the cross bar is slidably connected to the first shell, and the left end of the cross bar is tightly pressed against the box body.

[0010] Preferably, both upper and lower ends of the second sliding rod are fixedly connected to the second shell, and both upper and lower ends of the threaded rod are rotatably connected to the second shell via bearings.

[0011] Preferably, a stirring rod is fixedly connected to the lower end of the second gear rotating shaft, the outer wall of the stirring rod is rotationally connected to the second block through a bearing, and the outer wall of the second block is slidingly connected to the second shell.

[0012] The utility model proposes a heating and mixing device for preparing environmentally friendly furan resin, which has the following beneficial effects: through the cooperation of the material mixing structure, the heating structure and the second shell, the output shaft of the second motor rotates to drive the first gear to rotate, and the rotation of the first gear drives the stirring rod to rotate. The rotation of the stirring rod mixes the environmentally friendly furan resin, the movement of the threaded block drives the movement of the first block, and the movement of the first block drives the stirring rod downward through the second gear. The output shaft of the third motor rotates in the direction opposite to the above-mentioned movement direction, and the third motor drives the stirring rod upward through the above-mentioned connection method, so that the stirring rod performs a lifting movement when rotating, so that the environmentally friendly furan resin can flow fully in the entire box. During the descent process, the stirring rod flips the environmentally friendly furan resin at the bottom upward, and at the same time brings the environmentally friendly furan resin on the upper layer to the lower layer, thereby breaking the original temperature stratification, so that heat is more evenly transferred to various parts of the resin, eliminating the temperature gradient inside the environmentally friendly furan resin, and making the environmentally friendly furan resin as a whole more evenly heated.

[0013] Through the cooperation of the auxiliary blanking structure and the first shell, the output shaft of the first motor rotates to drive the cam to rotate clockwise, and the rotation of the cam compresses the torsion spring. The rotation of the cam drives the ring to move to the right through the pull rope, and the movement of the ring drives the cross bar to slide to the right on the first slide bar. When the torsion spring is compressed to the extreme, the first motor is turned off. At this time, the torsion spring rebounds to make the cam rotate counterclockwise rapidly. The cam drives the cross bar to move quickly to the left and knock on the box body through the above-mentioned connection method. A rubber pad is installed at the contact position between the cross bar and the box body. The rubber pad has good buffering performance. When the cross bar hits the object, the rubber pad can absorb part of the impact force, making the force transmitted to the knocked object softer. Knocking can prevent the environmentally friendly furan resin from sticking to the feed port during the feeding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Working principle:

[0033] Operation of heating and mixing device for preparation of environmentally friendly furan resin:

[0034] The feeding stage of environmentally friendly furan resin:

[0035] Start the heating block 10. A resistance wire is installed inside the heating block 10. The resistance wire is connected to an external power supply. The heating block 10 can heat the inside of the box 1 and heat the box 1 to a required temperature. At this time, the operator takes out the cover on the upper end of the feed port 8 and pours the environmentally friendly furan resin. After pouring, the cover is covered on the upper end of the feed port 8. A sealing strip is installed at the position where the cover contacts the feed port 8 to prevent heat loss.

[0036] Connect the external power supply of the first motor 301, start the first motor 301, and the output shaft of the first motor 301 rotates to drive the cam 302 to rotate clockwise. The rotation of the cam 302 compresses the torsion spring 303 (as shown in FIG. Figure 6 ), the cam 302 rotates and drives the ring 305 to move to the right through the pull rope 304, and the movement of the ring 305 drives the cross bar 306 to slide to the right on the first slide bar 307. When the torsion spring 303 is compressed to the extreme, the first motor 303 is turned off. At this time, the torsion spring 303 rebounds and causes the cam 302 to rotate counterclockwise rapidly. The cam 302 drives the cross bar 306 to move quickly to the left and knock on the box body 1 through the above-mentioned connection method. A rubber pad is installed at the contact position between the cross bar 306 and the box body 1. The rubber pad has good buffering performance. When the cross bar 306 knocks on an object, the rubber pad can absorb part of the impact force, making the force transmitted to the knocked object softer. The knocking can prevent the environmentally friendly furan resin from sticking to the feed port during the feeding process, and the first motor 301 is turned off.

[0037] Heating and mixing stage of environmentally friendly furan resin:

[0038] The external power supply of the second motor 501 is turned on, the second motor 501 is started, and the output shaft of the second motor 501 rotates to drive the first gear 502 to rotate (as shown in FIG. Figure 3), the first gear 502 rotates to drive the second gear 503 to rotate, the second gear 503 rotates to drive the stirring rod 6 to rotate, the rotation of the stirring rod 6 mixes the environmentally friendly furan resin, the external power supply of the third motor 505 is connected, the third motor 505 is started, the output shaft of the third motor 505 rotates to drive the threaded rod 506 to rotate, the threaded rod 506 rotates to drive the threaded block 507 to slide downward on the second slide bar 508, the threaded block 507 moves to drive the first block 504 to move, the first block 504 moves through the second gear 503 to drive the stirring rod 6 to move downward, the output shaft of the third motor 505 rotates in the direction opposite to the above-mentioned movement direction, and the third The motor 505 drives the stirring rod 6 to move upward through the above-mentioned connection method, so that the stirring rod 6 performs a lifting movement while rotating, and the second motor 501 and the third motor 505 are turned off, so that the environmentally friendly furan resin can flow fully in the entire box 1. During the descending process, the stirring rod 6 flips the environmentally friendly furan resin at the bottom upward, and at the same time brings the upper layer of environmentally friendly furan resin to the lower layer, thereby breaking the original temperature stratification, so that heat is more evenly transferred to various parts of the resin, eliminating the temperature gradient inside the environmentally friendly furan resin, and making the environmentally friendly furan resin as a whole more evenly heated. When heat is continuously provided by the heating block 10, the mixed heating operation of the environmentally friendly furan resin is completed.

[0039] Removal of environmentally friendly furan resin:

[0040] Open the solenoid valve, and the environmentally friendly furan resin flows into the collection bucket below through the discharge port 9. At this time, the box body 1 can be knocked by the auxiliary unloading structure 3 to reduce the adhesion of the environmentally friendly furan resin during the unloading process, prevent problems such as uneven unloading or interruption due to blockage, and make the residual environmentally friendly furan resin fall off under the action of vibration and impact force, which can greatly reduce the amount of environmentally friendly furan resin remaining after each production and improve the utilization rate of environmentally friendly furan resin. It is further explained that when the environmentally friendly furan resin is heated and mixed, the box body 1 can be knocked by the auxiliary unloading structure 3. The vibration and impact force generated by the knocking can make the resin more fully mixed and flow in the equipment. The environmentally friendly furan resin will partially agglomerate or flow poorly due to viscosity and other reasons, resulting in some environmentally friendly furan resin unable to fully participate in the chemical reaction. The knocking vibration can break these agglomerates, so that the environmentally friendly furan resin molecules can better contact and promote the chemical reaction. After the environmentally friendly furan resin is taken out, all power supplies are turned off, and the processing process of the heating and mixing device for preparing environmentally friendly furan resin is completed.
