Description

Technical Field

[0001] This utility model relates to the technical field of chemical raw material processing, specifically to a rapid dehydration device for epoxy resin production. Background Technology

[0002] Epoxy resin is a high molecular weight polymer with the molecular formula (C11H12O3)n. It refers to a class of polymers containing two or more epoxy groups in their molecules. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical reactivity of epoxy groups, it can be ring-opened by various compounds containing active hydrogen, and then cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin. In the production process of epoxy resin, in order to obtain epoxy resin with high purity, it is necessary to dehydrate the epoxy resin.

[0003] Existing dehydration equipment for epoxy resin production evaporates impurities inside the epoxy resin by heating it in a container. However, since the heating is only at the edge of the container, the evaporation of impurities inside the epoxy resin is insufficient, the time required for complete evaporation is too long, and the evaporated impurities contain a large amount of organic waste gas. Direct discharge into the air will have an adverse impact on human health and the ecological environment.

[0004] A search revealed that Chinese Patent CN202322012680.6 discloses a rapid dehydration device for epoxy resin production. The device includes a base plate, a power supply box on one side of the top surface of the base plate, a resin storage box on top of the power supply box, a feeding channel on one side of the resin storage box, a dehydration hood on one side of the feeding channel, two sets of rollers on the bottom of the inner walls of both sides of the dehydration hood, a dehydration inner liner on top of the rollers, a drive motor on one side of the bottom of the dehydration hood, the drive motor's power output connected to one set of rollers, and a discharge port on one side of the bottom of the dehydration inner liner, which passes through the dehydration hood. The device uses a drive motor, rollers, a dehydration inner liner, and a heating plate. The drive motor drives the rollers to rotate, which in turn drives the dehydration inner liner on top to rotate, allowing the epoxy resin inside the dehydration inner liner to flow. This ensures complete evaporation of impurities within the epoxy resin, improving the quality of the epoxy resin, reducing dehydration time, and increasing production efficiency.

[0005] While the above solutions can make the material heat more evenly and dehydrate more thoroughly, they are not convenient for subsequent resin extraction. Also, because the resin rotates inside, it will circulate and block the exhaust position, making it difficult for water vapor to escape. Therefore, we provide a rapid dehydration device for epoxy resin production to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rapid dehydration device for epoxy resin production that is easy to discharge, safe to vent, and has high dehydration efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The device includes a dehydration and placement chamber, with a support fixed to the outside of the chamber. A sealing plate is fixed to the top of the chamber, and a feed inlet is provided on the sealing plate. A cover plate is snapped into the feed inlet. A gas recovery component is fixed near the top of the chamber, and a base is slidably connected near the bottom. A heating and stirring component is rotatably connected to the center of the sealing plate. Heating resistance plates are covered on the sides of the chamber, and several through holes are provided on the sealing plate near the inner wall of the chamber.

[0009] Furthermore, a guide block is fixed inside the base. The guide block is tapered and has an outlet on the side of the base that extends through both sides of the base.

[0010] By adopting the above technical solution, epoxy resin can be easily dispersed and quickly exported.

[0011] Furthermore, a piston rod is fixed to the bottom of the base, and a cylinder is fixed to the end of the piston rod away from the base. The cylinder is fixed between the brackets.

[0012] By adopting the above technical solution, the base can move up and down, which facilitates the quick export of internal epoxy resin after dehydration, without the need to flip the dehydration box to retrieve the material, thus improving work efficiency.

[0013] Furthermore, the gas recovery component includes an annular gas collection box fixed to the top of the dehydration placement box. The annular gas collection box has a gas guide plate at the end facing the inside of the dehydration placement box. The gas guide plate communicates with the through hole on the sealing plate. A gas emission plate is fixed at the end of the annular gas collection box away from the dehydration placement box. The gas emission plate has several air holes. A gas adsorbent is placed inside the annular gas collection box.

[0014] By adopting the above technical solution, since the two ends of the dehydration placement box are sealed by a sealing plate and a base, water vapor enters the annular gas collection box through the through hole on the sealing plate. After the internal gas adsorbent adsorbs impurities and harmful gases, it is discharged through the air hole on the gas emission plate, thus avoiding the emission of harmful substances.

[0015] Furthermore, the heating and stirring component includes a metal sleeve rotatably connected to the sealing plate, a heating resistance rod placed inside the metal sleeve, and a motor connected to the top of the metal sleeve, with the motor fixed to the sealing plate.

[0016] By adopting the above technical solution, the metal sleeve absorbs heat, and heating can be carried out through the metal sleeve.

[0017] Furthermore, a plurality of metal stirring rods are welded to the side of the metal sleeve, and the metal stirring rods are provided in a plurality along both the circumferential and length directions of the metal sleeve.

[0018] By adopting the above technical solution, the heat is absorbed by the metal sleeve, so that both the metal sleeve and the external metal stirring rod carry heat. As the metal sleeve rotates, heating and stirring can be carried out inside the epoxy resin, thereby improving the dehydration efficiency.

[0019] In summary, the beneficial technical effects of this utility model are as follows:

[0020] 1. A ring-shaped gas recovery box is adopted. Since the two ends of the dehydration placement box are sealed by a sealing plate and a base, water vapor enters the ring-shaped gas collection box through the through hole on the sealing plate. After the impurities and harmful gases are adsorbed by the internal gas adsorbent, it is discharged through the air hole on the gas emission plate, thus avoiding the emission of harmful substances.

[0021] 2. A metal sleeve and an internal heating resistance rod are used, which allows the metal sleeve to absorb heat. The heat can be absorbed by the metal sleeve, and the heat is carried by both the metal sleeve and the external metal stirring rod. As the metal sleeve rotates, it can heat and stir inside the epoxy resin, thereby improving the dehydration efficiency.

[0022] 3. A base is used, which can move up and down, making it easy to quickly export the internal epoxy resin after dehydration without having to flip the dehydration chamber to retrieve the material, thus improving work efficiency. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4 The present invention provides a technical solution comprising: a dehydration placement box 1, a bracket 2 fixed to the outside of the dehydration placement box 1, a sealing plate 3 fixed to the top of the dehydration placement box 1, a feed inlet 4 on the sealing plate 3, a cover plate 5 snapped into the feed inlet 4, a gas recovery component fixed near the top of the dehydration placement box 1, a base 6 slidably connected near the bottom of the dehydration placement box 1, a heating and stirring component rotatably connected to the center of the sealing plate 3, a heating resistance plate 7 covering the side of the dehydration placement box 1, and several through holes 8 on the side of the sealing plate 3 near the inner wall of the dehydration placement box 1.

[0032] Inside the base 6, there is a guide block 9. The guide block 9 is conical and has an outlet 10 on the side of the base 6 that runs through both sides of the base 6. The epoxy resin particles inside the dehydrated storage box 1 can slide freely along the guide block 9 to the periphery of the guide block 9. The outlet 10 on the side of the base 6 facilitates the complete discharge of the epoxy resin particles inside, thus improving the collection efficiency.

[0033] Meanwhile, a piston rod 11 is fixed at the bottom of the base 6, and a cylinder 12 is fixed at the end of the piston rod 11 away from the base 6. The cylinder 12 is fixed between the brackets 2. After dehydration is completed, the cylinder 12 can be opened, and the piston rod 11 can be driven to move downward through the cylinder 12, so that the outlet 10 is exposed outside the dehydration placement box 1, which is convenient for collecting the epoxy resin particles that have been dehydrated inside.

[0034] The gas recovery unit includes an annular gas collection box 13 fixed to the top of the dehydration chamber 1. The annular gas collection box 13 facing the inside of the dehydration chamber 1 has a gas guide plate 14, which is connected to the through hole 8 on the sealing plate 3. The annular gas collection box 13 away from the dehydration chamber 1 has a gas discharge plate 15 fixed to it. The gas discharge plate 15 has several vents 16. The annular gas collection box 13 contains a gas adsorbent. The water vapor generated during the heating and dehydration process enters the annular gas collection box 13 through the through hole 8 on the sealing plate 3 because the two ends of the dehydration chamber 1 are sealed by the sealing plate 3 and the base 6, respectively. After the water vapor is adsorbed by the internal gas adsorbent to remove impurities and harmful gases, it is discharged through the vents 16 on the gas discharge plate 15. The gas adsorbent includes alkaline particles and activated carbon particles. Specifically, dehydration is achieved by heating to evaporate water vapor. The heating and stirring component includes a metal sleeve 17 rotatably connected to the sealing plate 3. A heating resistance rod 18 is placed inside the metal sleeve 17. A motor 19 is connected to the top of the metal sleeve 17 and is fixed to the sealing plate 3.

[0035] Meanwhile, several metal stirring rods 20 are welded to the side of the metal sleeve 17. Several metal stirring rods 20 are provided along the circumference and length of the metal sleeve 17. After the heating resistance rod 18 is turned on, the heat generated on its surface is absorbed by the metal sleeve 17, so that the metal sleeve 17 and the external metal stirring rods 20 carry heat. As the metal sleeve 17 rotates, heating and stirring can be carried out inside the epoxy resin.

[0036] The working principle of this utility model is as follows: A metal sleeve 17 and a metal stirring rod 20 for stirring are set inside the dehydration chamber 1. At the same time, a heating resistance rod 18 is built into the metal sleeve 17. Thus, the metal sleeve 17 and the metal stirring rod 20 can heat the internal epoxy resin during stirring. Combined with the external heating resistance plate 7, heating is carried out from the inside to the outside, which effectively improves the efficiency of heating and dehydration. Meanwhile, the annular gas recovery box set above can fully export the generated water vapor and adsorb the internal harmful gases to avoid the emission of harmful substances.
