Description

Technical Field

[0001] This utility model relates to the technical field of insulating varnish preparation equipment, specifically to a reaction vessel for preparing insulating varnish with a water vapor collection structure. Background Technology

[0002] In the preparation of insulating varnish, the reactor is the core equipment, and its stability and efficiency play a key role in the product quality. Traditional reactors used for preparing insulating varnish have many drawbacks, among which the problem of water vapor treatment is particularly prominent.

[0003] A search revealed that patent publication number CN217473520U discloses a reaction vessel for preparing oil-based insulating varnish. The vessel includes a reaction vessel body with a hemispherical top surface. An inlet is installed on the hemispherical top surface, offset from the center. The inner wall of the reaction vessel body is equipped with electric heating elements. An outlet is installed in the middle of the side of the reaction vessel body. A stirring device includes a drive motor, the power output shaft of which is powered and connected to a planetary reducer. The bottom end of the planetary reducer is powered and connected to a transmission shaft. A stirring shaft is nested on the bottom side of the transmission shaft. The planetary reducer is installed at the center of the top surface of the reaction vessel body. A recovery device includes a condenser pipe and a liquid separator connected to the condenser pipe via a pipe. This invention can remove moisture from the reaction vessel, promoting a forward reaction, increasing the reaction yield, and simultaneously recovering raw materials, reducing resource waste.

[0004] In the actual process of preparing insulating varnish, existing reaction vessels often generate water vapor. If this water vapor is not effectively collected and treated, it will interfere with the reaction environment. For example, excessive water vapor will change the humidity of the reaction system, affect the progress of certain humidity-sensitive chemical reactions, and thus reduce the quality stability and performance consistency of the insulating varnish. This will cause fluctuations in key properties such as electrical insulation and chemical corrosion resistance. Furthermore, the direct emission of water vapor generated during the reaction not only wastes resources but may also have a certain impact on the environment. Therefore, a reaction vessel for preparing insulating varnish with a water vapor collection structure is designed. Utility Model Content

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a reaction vessel for preparing insulating varnish with a water vapor collection structure, including a reaction vessel body for preparing insulating varnish, and a water vapor collection mechanism for receiving water vapor discharged from the reaction vessel body on one side of the reaction vessel body.

[0008] The water vapor collection mechanism is equipped with a water vapor condensation component for condensing water vapor, and a heat exchange component for receiving the condensate discharged from the water vapor condensation component and exchanging heat between the condensate and the cleaning liquid.

[0009] Preferably, the heat exchange assembly is provided with a condensate collection tank, and a heat-conducting tank is installed at the top of the condensate collection tank. The outer circumferential wall of the heat-conducting tank is provided with annular heat-conducting fins arranged in a rectangular array, and a heat-conducting coil is provided inside the heat-conducting tank.

[0010] Preferably, the discharge end of the heat-conducting coil is connected to the drain pipe through a pipe joint, the other end of the drain pipe passes through the bottom of the heat-conducting tank and extends into the interior of the condensate collection tank, and a one-way valve is provided on the drain pipe, and an electric heating plate is provided on the circumferential inner wall of the heat-conducting tank.

A condensate outlet pipe is provided below one side of the outer circumferential wall of the condensate collection tank, and the condensate outlet pipe is equipped with a valve body.

[0012] Preferably, the water vapor condensation assembly is provided with a first housing, and a second housing and a fan arranged in a rectangular array are installed on both outer walls of the first housing. The fan is located inside the second housing. A ventilation hole is provided on one side of the fan and is opened on both outer walls of the first housing. A plate air filter is provided on the other side of the fan.

[0013] Preferably, the top and bottom ends of the plate air filter are both installed in the U-shaped groove of the U-shaped plate, and the outer walls of both ends of the plate air filter are in clearance fit with the groove wall of the U-shaped groove. The U-shaped plate is installed at the top and bottom ends inside the second housing, and an air inlet slot is provided on one side of the outer wall of the second housing.

[0014] Preferably, a condenser coil is provided inside the first housing. The input end of the condenser coil is connected to the air inlet pipe through a pipe joint. The other end of the air inlet pipe passes through the top of the first housing and is connected to the drain gas end of the reactor body through a conveying pipe. The drain gas end is provided with a one-way valve. The discharge end of the condenser coil is connected to the liquid outlet pipe through a pipe joint.

[0015] Preferably, the other end of the outlet pipe passes through the bottom of the first shell, the top of the condensate collection tank and the top of the heat transfer tank in sequence, extends into the interior of the heat transfer tank and is connected to the input end of the heat transfer coil through a pipe joint.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. In this utility model, through a series of structural arrangements, the water vapor generated during the preparation of insulating varnish in the reactor body is transported to the condensing coil on the water vapor condensation assembly through the drain valve and the conveying pipe. The fan on the condensing assembly is started to dissipate heat from the condensing coil. The water vapor condenses in the condensing coil, and the condensate formed by the condensation is discharged into the heat-conducting coil through the liquid outlet pipe. When the condensate flows in the heat-conducting coil, the heat in the condensate is transferred to the heat-conducting coil, and the heat on the heat-conducting coil is transferred to the clean liquid inside the heat-conducting tank, realizing the first heat exchange between the condensate and the clean liquid. When the condensate is discharged into the condensate collection tank through the drain pipe, the heat on the condensate is transferred to the clean liquid again through the annular heat-conducting fins and the heat-conducting tank, realizing the second heat exchange, thereby effectively improving the heat exchange efficiency.

[0018] 2. In this utility model, through a series of coordinated structural arrangements, when water vapor enters the heat-conducting coil, the clean liquid in the heat-conducting tank exchanges heat with the water vapor in the heat-conducting coil, thereby enabling secondary condensation of the water vapor and improving the water vapor condensation effect.

[0019] Therefore, as can be seen from the above, this utility model can not only condense and collect the water vapor generated during the preparation of insulating varnish in the reactor body, but also condense the water vapor into heat in the condensate to preheat the cleaning liquid, so that the interior of the reactor body can be cleaned by the heated cleaning liquid. This realizes the recovery and utilization of waste heat, improves energy utilization, and reduces production costs. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0033] like Figure 1-4 As shown, a reaction vessel for preparing insulating varnish with a water vapor collection structure includes a reaction vessel body 100 for preparing insulating varnish, and a water vapor collection mechanism 200 for receiving water vapor discharged from the reaction vessel body 100 is provided on one side of the reaction vessel body 100.

[0034] The water vapor collection mechanism 200 is provided with a water vapor condensation component 210 for condensing water vapor, and a heat exchange component 220 for receiving the condensate discharged from the water vapor condensation component 210 and exchanging heat between the condensate and the clean liquid.

[0035] The heat exchange assembly 220 is equipped with a condensate collection tank 221. A heat conduction tank 222 is installed at the top of the condensate collection tank 221. The outer circumferential wall of the heat conduction tank 222 is provided with annular heat conduction fins 224 arranged in a rectangular array. A heat conduction coil 223 is provided inside the heat conduction tank 222. The arrangement of the annular heat conduction fins 224 increases the heat conduction area between the condensate inside the condensate collection tank 221 and the heat conduction tank 222, thereby improving the heat exchange effect between the condensate inside the condensate collection tank 221 and the clean liquid.

[0036] The discharge end of the heat transfer coil 223 is connected to the drain pipe 225 through a pipe joint. The other end of the drain pipe 225 passes through the bottom of the heat transfer tank 222 and extends into the interior of the condensate collection tank 221. A one-way valve is installed on the drain pipe 225. An electric heating plate is installed on the circumferential inner wall of the heat transfer tank 222. When the electric heating plate is activated, it can heat the clean liquid inside the heat transfer tank 222.

[0037] The heat transfer tank 222 has a cleaning liquid addition pipe and a cleaning liquid discharge pipe installed on the upper and lower sides of the outer wall side, respectively, and both the cleaning liquid addition pipe and the cleaning liquid discharge pipe are equipped with valve bodies. The condensate collection tank 221 has a condensate discharge pipe installed on the lower side of the outer wall side, and the condensate discharge pipe is equipped with a valve body.

[0038] The water vapor condensation assembly 210 is provided with a first housing 212. A second housing 214 and a fan 216 arranged in a rectangular array are installed on both outer walls of the first housing 212. The fan 216 is located inside the second housing 214. A ventilation hole is provided on one side of the fan 216, and the ventilation hole is opened on both outer walls of the first housing 212. A plate air filter 217 is provided on the other side of the fan 216. The plate air filter 217 can filter dust particles in the outside air, preventing dust particles in the outside air from being blown towards the condenser coil 211 and causing the condenser coil 211 to absorb a large amount of dust particles, which would reduce the water vapor condensation effect.

[0039] The top and bottom of the plate air filter 217 are installed in the U-shaped groove on the U-shaped clamping plate 215, and the outer walls of both ends of the plate air filter 217 are clearance-fitted with the groove wall of the U-shaped groove. Because the outer walls of both ends of the plate air filter 217 are clearance-fitted with the groove wall of the U-shaped groove, the staff can disassemble, replace or clean the plate air filter 217. The U-shaped clamping plate 215 is installed at the top and bottom of the inner side of the second housing 214, and an air inlet slot is opened on one side of the outer wall of the second housing 214.

[0040] The first housing 212 is equipped with a condenser coil 211. The input end of the condenser coil 211 is connected to the air inlet pipe 213 through a pipe joint. The other end of the air inlet pipe 213 passes through the top of the first housing 212 and is connected to the drain steam end of the reactor body 100 through a conveying pipe. The drain steam end is equipped with a one-way valve. The discharge end of the condenser coil 211 is connected to the liquid outlet pipe 218 through a pipe joint.

[0041] The other end of the outlet pipe 218 passes through the bottom of the first housing 212, the top of the condensate collection tank 221 and the top of the heat transfer tank 222 in sequence, extends into the interior of the heat transfer tank 222 and is connected to the input end of the heat transfer coil 223 through a pipe joint. Safety doors are provided on the front wall of the first housing 212 and the front wall of the second housing 214. Ventilation slots are provided on the rear wall of the first housing 212 and the safety doors on the first housing 212.

[0042] Working principle: When in use, after connecting to an external power source, the water vapor generated during the preparation of insulating varnish in the reactor body 100 will be transported through the drain pipe and conveying pipe to the condensing coil 211 on the water vapor condensation assembly 210. The fan 216 on the condensation assembly will start to dissipate heat from the condensing coil 211. The water vapor will condense in the condensing coil 211, and the condensate formed will be discharged into the heat-conducting coil 223 through the liquid outlet pipe 218. When the condensate flows in the heat-conducting coil 223, the heat in the condensate will be transferred to the heat-conducting coil 223, and the heat on the heat-conducting coil 223 will be transferred to the clean liquid inside the heat-conducting tank 222, realizing the first heat exchange between the condensate and the clean liquid. When the condensate is discharged into the condensate collection tank 2 through the drain pipe 225... Inside the reactor body 21, the heat from the condensate is transferred to the cleaning liquid again through the annular heat-conducting fins 224 and the heat-conducting tank 222, achieving a second heat exchange and effectively improving the heat exchange efficiency. When water vapor enters the heat-conducting coil 223, the cleaning liquid in the heat-conducting tank 222 exchanges heat with the water vapor in the heat-conducting coil 223, thereby enabling secondary condensation of the water vapor and improving the condensation effect. Thus, this invention can not only condense and collect the water vapor generated during the preparation of insulating varnish in the reactor body 100, but also condense the water vapor into the heat in the condensate to preheat the cleaning liquid, so that the interior of the reactor body 100 can be cleaned by the heated cleaning liquid. This achieves waste heat recovery and utilization, improves energy utilization, and reduces production costs.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
