Description

Technical Field

[0001] This utility model relates to the field of epoxy resin production technology, and more specifically, to a dehydration device for epoxy resin production and processing. Background Technology

[0002] Epoxy resin is a high molecular weight polymer, referring to a class of polymers containing two or more epoxy groups in their molecules. Due to its strong adhesion, low shrinkage, and excellent mechanical and electrical properties, epoxy resin is widely used in coatings, adhesives, and electronic appliances. Most existing epoxy resins are produced through the condensation reaction of bisphenol A and epichlorohydrin. However, this condensation reaction generates a large amount of water, which can severely affect the molecular weight, curing properties, and stability of the product. Therefore, it is necessary to remove the moisture from the epoxy resin raw materials to avoid affecting product quality.

[0003] Existing dehydration devices for epoxy resin production, such as the rapid dehydration equipment for epoxy resin production (patent number CN220417904U), include a storage tank, a dehydration outer casing, a dehydration inner tank, rollers, a drive motor, an exhaust gas conveying pipe, and a heat-generating plate positioned between the outer casing and the inner tank. The equipment feeds liquid epoxy resin into the inner tank through the storage tank. The drive motor rotates the rollers, causing the inner tank and the liquid epoxy resin within it to rotate. Simultaneously, the heat-generating plate heats the liquid epoxy resin in the inner tank, causing the water in the liquid epoxy resin to evaporate and be discharged through the outlet. This dehydration device heats and evaporates the liquid epoxy resin under normal pressure. At normal pressure, the evaporation temperature of liquid water is relatively high, resulting in low evaporation efficiency. Utility Model Content

[0018] 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.

[0019] Please see Figure 1 and Figure 2This utility model provides a dehydration device for epoxy resin production and processing, comprising: a dehydration tank 10, which is a sealed tank; a stirring mechanism 20, disposed at the center inside the dehydration tank 10, for stirring the epoxy resin; a heating mechanism 30, disposed inside the dehydration tank 10, for heating and evaporating the moisture in the epoxy resin; and a vacuum mechanism 40, disposed on the dehydration tank 10, including a vacuum pump 41 and a pressure stabilizing component 42. The vacuum pump 41 is disposed at the top outside the dehydration tank 10, for extracting air from inside the dehydration tank 10. The pressure stabilizing component 42 is disposed inside the dehydration tank 10 and connected to the vacuum pump 41, for improving the air extraction stability of the vacuum pump 41.

[0020] Understandably, the dehydration tank 10 is a hollow tank, such as a square tank or a cylindrical tank, but not limited to these. The stirring mechanism 20 is a component that ensures the epoxy resin inside the dehydration tank 10 is fully heated, such as a mechanical stirring mechanism 20 or a bubble stirring mechanism 20, but not limited to these. The heating mechanism 30 is a component that heats the moisture inside the epoxy resin to vaporize it, such as an electric heating mechanism 30 or an infrared heating mechanism 30, but not limited to these. The vacuum pump 41 is a component that reduces the air pressure inside the dehydration tank 10, such as a positive displacement vacuum pump 41 or a momentum transfer vacuum pump 41, but not limited to these. The pressure stabilizing component 42 is a component that stabilizes the vacuum pump 41, such as a vacuum buffer tank 421 or a pressure regulating valve, but not limited to these. As described above, the equipment is equipped with a vacuum mechanism 40. A vacuum pump 41 within the vacuum mechanism 40 extracts air from the dehydration tank 10. The installed pressure stabilizing component 42 stabilizes the air extraction speed of the vacuum pump 41, improving extraction efficiency and causing a rapid drop in air pressure within the dehydration tank 10. This lowers the boiling point of water, increases dehydration efficiency, and reduces energy consumption. The equipment also includes a stirring mechanism 20, which stirs the internal epoxy resin, ensuring that the heating mechanism 30 fully and evenly heats the epoxy resin, further improving dehydration efficiency and quality.

[0021] Optionally, in some embodiments, please refer to Figure 3 The vacuum mechanism 40 also includes a housing 43 disposed at the top inside the dehydration tank 10 for mounting the pressure stabilizing component 42, and a pressure gauge 44 disposed at the top of the dehydration tank 10 and connected inside the dehydration tank 10 for measuring the internal air pressure of the dehydration tank 10. A mounting hole is provided on one side of the housing 43.

[0022] Understandably, the outer casing 43 is the housing that supports and installs the pressure stabilizing component 42 inside the dehydration tank 10. For example, it can be a metal casing 43 or a plastic casing 43, but it is not limited to these. The pressure gauge 44 is a component that measures whether the air pressure inside the dehydration tank 10 is positive or negative. For example, it can be a liquid column pressure gauge 44 or an elastic pressure gauge 44, but it is not limited to these.

[0023] With this configuration, pressure gauge 44 can visualize the pressure value inside dehydration tank 10, ensuring that the pressure is within the required range.

[0024] Optionally, in some embodiments, please refer to Figure 3 The voltage stabilizing assembly 42 includes: a buffer tank 421, disposed within the housing 43, for stabilizing the pumping stability of the vacuum pump 41; an outlet pipe 422, disposed within the housing 43 and connecting the vacuum pump 41 and the buffer tank 421, for delivering air to the vacuum pump 41; and an inlet pipe 423, disposed within the dehydration tank 10 and passing through the housing 43 and connected to the buffer tank 421, for drawing in air from the dehydration tank 10.

[0025] Understandably, the buffer tank 421 is a device that can stabilize the pressure of the vacuum pump 41, ensure that the vacuum pump 41 can stably extract air, and also separate impurities in the air to prevent impurities from damaging the components of the vacuum pump 41. For example, it can be a filter-type buffer tank 421 or a heating-type buffer tank 421, but it is not limited to these.

[0026] With this configuration, when the vacuum pump 41 extracts air from the dehydration tank 10, the buffer tank 421 can not only ensure that the vacuum pump 41 can stably increase the air extraction speed and improve the extraction efficiency, but also filter impurities in the air to protect the vacuum pump 41 and extend its service life.

[0027] Optionally, in some embodiments, please refer to Figure 3 The air inlet pipe 423 is set perpendicular to the suction direction of the vacuum pump 41.

[0028] It is understandable that the air intake pipe 423 draws air into the buffer tank 421 from the side, for example, it can be installed on the left side of the buffer tank 421 or on the right side of the buffer tank 421, but it is not limited to this.

[0029] This design prevents air from directly impacting the buffer tank 421 and vacuum pump 41 when vacuum pump 41 draws in air, thus avoiding instability of vacuum pump 41 and buffer tank 421 and affecting pumping efficiency.

[0030] Optionally, in some embodiments, please refer to Figure 2 The stirring mechanism 20 includes: a rotary driver 21, which is disposed at the center inside the dehydration tank 10 and is used for rotational driving; and blades 22, which are disposed inside the dehydration tank 10 and connected to the output end of the rotary driver 21, and are used for stirring.

[0031] Understandably, the rotary actuator 21 is the component that drives the blade 22 to rotate; it can be a hydraulic actuator, an electric actuator, or something similar, but is not limited to these. The blade 22 is the component that agitates the epoxy resin under the drive of the rotary actuator 21; it can be an anchor-type agitator blade 22, a ribbon-type agitator blade 22, or something similar, but is not limited to these.

[0032] With this configuration, the stirring blades and rotary drive 21 can make the epoxy resin flow, so that the heating mechanism 30 can heat the epoxy resin in the dehydration tank 10 evenly and fully, avoiding uneven heating that would lead to insufficient water evaporation and affect product quality.

[0033] Optionally, in some embodiments, please refer to Figure 2 The heating mechanism 30 includes: a plurality of heating tubes 31 disposed inside the dehydration tank 10 and surrounding the stirring mechanism 20, for heating the epoxy resin; and a sensing element 32 disposed in a ring on the inner wall of the dehydration tank 10 for sensing the heat of the epoxy resin.

[0034] Understandably, the heating element 31 is the component for evaporating moisture from the epoxy resin. The number and arrangement of the heating elements 31 affect the heating effect. For example, there can be a single heating element 31 located in the center of the dehydration tank 10, or multiple heating elements 31 arranged in a ring evenly inside the dehydration tank 10, etc., but it is not limited to these arrangements. Since the latter arrangement can evaporate the moisture more quickly and thoroughly, the latter method is recommended. The sensing element 32 is a component that assists in controlling the internal temperature of the dehydration tank 10. For example, it can be an infrared temperature sensor, a pyroelectric sensor, etc., but it is not limited to these.

[0035] With this configuration, the multiple heating tubes 31 arranged in a ring can simultaneously evaporate the moisture inside the epoxy resin, improving the dehydration efficiency.

[0036] Optionally, in some embodiments, please refer to Figure 1 The dehydration device for epoxy resin production and processing also includes a waste heat recovery mechanism located on one side of the dehydration tank 10 and connected to a vacuum pump 41 for recovering the heat of water vapor in the dehydration tank 10.

[0037] Understandably, the waste heat recovery mechanism 50 is a component that recovers the energy within water vapor and liquefies the water vapor into liquid water. For example, it can be a condenser coil or a heat exchange recovery component, but it is not limited to these.

[0038] This configuration allows for the recovery of heat from water vapor through the waste heat recovery mechanism 50, preventing heat from escaping into the air and wasting energy, thus improving energy utilization.

[0039] Optionally, in some embodiments, please refer to Figure 2The waste heat recovery mechanism 50 includes: a heat exchanger 51, disposed on one side of the dehydration tank 10 and connected to a vacuum pump 41, for recovering heat from water vapor; a water tank 52, connected to the heat exchanger 51, for recovering water within the heat exchanger 51; and a connecting pipe 53, disposed between the heat exchanger 51 and the vacuum pump 41, connecting the vacuum pump 41 and the dehydration tank 10.

[0040] Understandably, heat exchanger 51 is a component that absorbs heat from water vapor using water or other substances as a medium. For example, it can be a shell-and-tube heat exchanger 51, or a plate heat exchanger 51, but it is not limited to these. Water tank 52 is a tank used to store water. Since the dehydration system needs to operate in a vacuum environment, water tank 52 is a sealed tank. For example, it can be a one-piece molded sealed tank, or a sealed tank with the lid and tank body molded separately, but it is not limited to these.

[0041] With this configuration, the hot water generated after the heat exchanger 51 cools the steam can be used for domestic or industrial water use, improving energy utilization and saving energy.

[0042] As can be seen from the above, the epoxy resin to be dehydrated is injected into the dehydration tank 10, the vacuum pump 41 and the pressure stabilizing component 42 are turned on to extract the internal air. When the vacuum degree in the dehydration tank 10 reaches the specified value, the air pressure in the dehydration tank 10 is stabilized, the heating mechanism 30 and the stirring mechanism 20 are turned on to heat the epoxy resin to evaporate the moisture.

[0043] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
