Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, and in particular relates to a high-efficiency distillation device for the production of trimethylolpropane diallyl ether. Background Technology

[0002] Trimethylolpropane diallyl ether is a colorless to pale yellow transparent liquid, mainly used as a crosslinking agent, monomer or intermediate. It is widely used in the coatings industry, adhesives and electronic materials. Its synthesis involves stirring, heating and distilling the raw materials to be synthesized in a distillation tank. However, when cleaning the inside of the distillation tank, the existing technology leaves reactant residues on the inner wall of the tank, resulting in poor cleaning effect. In addition, the existing technology uses natural cooling steam to achieve the distillation effect, which also results in poor distillation effect.

[0003] To address these issues, we provide a high-efficiency distillation apparatus for the production of trimethylolpropane diallyl ether. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency distillation apparatus for the production of trimethylolpropane diallyl ether. This apparatus uses a scraper to remove residues from the inner wall of the distillation chamber and a pump to continuously deliver cold water to the hollow box. The steam rapidly condenses upon contact with the hollow box, solving the problems of poor cleaning results due to reactant residues remaining on the inner wall of the distillation chamber during cleaning, and the poor distillation effect caused by the use of naturally cooled steam in existing technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a high-efficiency distillation apparatus for the production of trimethylolpropane diallyl ether, comprising a heating mechanism, which includes a housing with a cover fixed to the upper wall of the housing. A motor is fixed to the middle of the upper wall of the cover, and a rotating rod is fixed to the power output shaft of the motor. A U-shaped rotating plate is fixed to the lower end of the rotating rod, and a scraper is fixed to the outer wall of the rotating plate. The distillation mechanism includes a collection box located on the right side of the housing, a U-shaped conveying pipe above the collection box, a motor fixed to the right end of the upper wall of the conveying pipe, a vertical rod fixed to the power output shaft of the motor, a fan blade fixed to the lower end of the vertical rod, a hollow box below the fan blade, a conveying pump in front of the collection box, and a water tank to the right of the collection box.

[0006] The present invention is further configured such that a heating wire is fixedly provided on the lower wall inside the box, and a partition fixed to the box is provided above the heating wire.

[0007] The present invention is further provided that a maintenance groove is provided on the left peripheral wall of the box above the partition, and a box door is provided on the left side of the maintenance groove by bolts.

[0008] The present invention is further configured such that the cross-section of the scraper is triangular, the outer end of the scraper contacts the inner peripheral wall of the box and the upper wall of the partition, and a connecting rod is fixedly provided on the inner side of the rotating plate, the other end of the connecting rod being fixedly connected to the rotating rod.

[0009] The present invention is further configured such that the lower left end of the conveying pipe is fixedly connected to the box cover, the lower right end of the conveying pipe is fixedly provided with an upper cover, the upper cover is fixedly connected to the collection box, and a connecting pipe is fixedly provided below the hollow box corresponding to the left wall of the collection box. The left end of the connecting pipe passes through the right wall of the box and extends into the interior of the box.

[0010] The present invention is further configured such that fixed pipes are fixed at both the front and rear ends of the hollow box, the outer end of the fixed pipe is located outside the collection box, and the fixed pipe is fixedly connected to the collection box. Water pipe one is fixed at both the inlet and outlet ends of the delivery pump. The other end of water pipe one at the inlet end of the delivery pump is fixed at the lower end of the front wall of the water tank. The other end of water pipe one at the outlet end of the delivery pump is fixedly connected to the fixed pipe located on the front side. Water pipe two is fixed at the rear end of the fixed pipe located on the rear side, and the other end of water pipe two is fixedly connected to the rear wall of the water tank.

[0011] The present invention is further configured such that an installation plate is fixedly provided on the lower wall of the pump, the installation plate is fixedly connected to the collection box, and support legs are fixedly provided at the four corners of the lower wall of the collection box and the water tank.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a motor and a scraper. The motor drives a rotating rod to rotate, which in turn rotates the rotating plate and the scraper. As the scraper rotates, its outer end contacts the inner wall of the chamber, scraping away any residue. The residue is then discharged through a maintenance groove. This solves the problem in existing technologies where reactant residue remains on the inner wall of the distillation chamber, resulting in poor cleaning.

[0013] 2. This utility model, by setting up a delivery pump, a water tank, and a hollow box, cools the water by vertically inserting ice blocks. The delivery pump then transports the cold water to the hollow box to absorb the heat from the box, lowering its temperature. When steam acts on the hollow box, it quickly condenses into a liquid and flows to the lower side of the collection tank. Compared with existing technologies, using a delivery pump to transport water cooled by ice blocks cools the hollow box, keeping it at a low temperature, which is more conducive to the rapid condensation of steam into a liquid state, improving the distillation effect. This solves the problem of poor distillation results caused by the use of natural cooling steam in existing technologies. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1 Please see Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present invention. This embodiment provides a high-efficiency distillation apparatus for the production of trimethylolpropane diallyl ether, including a heating mechanism 1. The heating mechanism 1 includes a box 104, which is generally circular. In order to facilitate the discharge of liquid inside the box 104, a liquid discharge valve is fixed on one side of the outer peripheral wall. A box cover 101 is fixed on the upper wall of the box 104. The box cover 101 is detachably fixed to the box 104. A motor 102 is fixed at the middle position of the upper wall of the box cover 101. A rotating rod 102a is fixed on the power output shaft of the motor 102. A U-shaped rotating plate 105 is fixed at the lower end of the rotating rod 102a. A scraper 105a is fixed on the outer wall of the rotating plate 105. The scraper 105a can be made of rubber. The rotating rod 102a is driven by the motor 102 to rotate, thereby causing the rotating plate 105 to rotate, so that the scraper 105a rotates to scrape off the residue on the inner peripheral wall of the box 104. Specifically, a heating wire 107 is fixedly installed on the lower wall inside the box 104 to generate heat to heat the raw materials inside the box 104. Above the heating wire 107, a partition 106 is fixed to the box 104. The partition 106 is made of a heat-conducting material, such as copper or aluminum, to facilitate the conduction of heat to the raw materials inside the box 104. A maintenance groove 104a is provided on the left peripheral wall of the box 104 above the partition 106. A box door 103 is provided on the left side of the maintenance groove 104a and is fixedly connected to the box 104 by bolts. A sealing gasket is also provided between the box door 103 and the box 104 to prevent leakage. At the same time, the box door 103 is detachably fixed to the box 104 by bolts. With the above configuration, by removing the box door 103 to expose the maintenance groove 104a, the scraper 105a can be rotated to allow the residue on the upper surface of the partition 106 to pass through the maintenance groove 104a and be discharged. The scraper 105a has a triangular cross-section. The outer end of the scraper 105a contacts the inner peripheral wall of the box 104 and the upper wall of the partition 106 respectively. A connecting rod 105b is fixedly provided on the inner side of the rotating plate 105. The other end of the connecting rod 105b is fixedly connected to the rotating rod 102a. The rotation of the connecting rod 105b can realize the function of stirring and mixing the raw materials inside the box 104. At the same time, it can also improve the connection stability between the rotating rod 102a and the rotating plate 105. The operation process of this embodiment is as follows: After distillation, the product distilled inside the box 104 is discharged by opening the liquid discharge valve. Then, the motor 102 is turned to drive the rotating rod 102a to rotate, so that the rotating plate 105 and the scraper 105a rotate. When the scraper 105a rotates, the residue on the inner wall of the box 104 is scraped off. The box door 103 is opened to expose the maintenance groove 104a. Under the continuous rotation of the scraper 105a, the residue on the upper surface of the partition 106 passes through the maintenance groove 104a and is discharged from the box 104.

[0023] Example 2 Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: the distillation mechanism 2 includes a collection box 205 located on the right side of the housing 104. A U-shaped conveying pipe 204 is provided above the collection box 205. The conveying pipe 204 can be made of a heat-conducting material, so that when steam enters the conveying pipe 204, it is in a cooling state, thereby maximizing the condensation effect of the steam. At the same time, the conveying pipe 204 can be inclined from left to right. When the steam enters the conveying pipe 204, it encounters cooling, and at this time, part of the steam condenses into liquid. In the inclined state of the conveying pipe 204, the liquid flows along the inside of the conveying pipe 204 to the inside of the collection box 205. A motor 201 is fixed to the right end of the upper wall of the conveying pipe 204. A vertical rod 201a is fixed to the power output shaft of the motor 201. A fan blade 202 is fixed to the lower end of the vertical rod 201a. The operation drives the vertical rod 201a to rotate, which in turn causes the fan blade 202 to rotate. At this time, under the action of the fan blade 202, the steam inside the box 104 passes through the conveying pipe 204 and enters the collection box 205 for condensation. The airflow then passes through the connecting pipe 205a and enters the box 104 to achieve internal circulation. A hollow box 203 is provided below the fan blade 202. A conveying pump 209 is provided in front of the collection box 205. A water tank 207 is provided to the right of the collection box 205. The water tank 207 contains water and ice. The melting ice can cool the water. The conveying pump 209 is used to transport the cooled water to the hollow box 203 to lower the temperature of the hollow box 203. The steam acts on the lower temperature hollow box 203 and quickly liquefies to form a liquid, thereby achieving the distillation effect. Valves are fixed at the bottom of the side walls of the water tank 207 and the collection box 205, respectively, for discharging the liquid inside the collection box 205 and the liquid inside the water tank 207. Specifically, the lower left end of the conveying pipe 204 is fixedly connected to the box cover 101. The interiors of the box body 104 and the collection box 205 are connected to the interior of the conveying pipe 204. The lower right end of the conveying pipe 204 is fixedly provided with an upper cover 208, which is fixedly connected to the collection box 205. The upper cover 208 is fixed to the collection box 205 by bolts to facilitate the disassembly of the upper cover 208. The lower part of the hollow box 203 is fixedly provided with a connecting pipe 205a corresponding to the left wall of the collection box 205. The left end of the connecting pipe 205a passes through the right wall of the box body 104 and extends into the interior of the box body 104, so that after the fan blade 202 rotates, the airflow circulates inside the conveying pipe 204, the box body 104 and the collection box 205. Both ends of the hollow box 203 are fixed with fixing pipes 203a. The outer end of the fixing pipe 203a is located outside the collection box 205 and is fixedly connected to the collection box 205. The interior of the fixing pipe 203a is connected to the interior of the hollow box 203. Both the inlet and outlet ends of the delivery pump 209 are fixed with water pipes 209a. The other end of the water pipe 209a at the inlet end of the delivery pump 209 is fixed to the lower end of the front wall of the water tank 207. The interior of the water pipe 209a is connected to the interior of the water tank 207. The water pipe at the outlet end of the delivery pump 209 is also fixed. The other end of water pipe 209a is fixedly connected to the fixed pipe 203a located on the front side. Water pipe 209a communicates with the interior of hollow box 203. Water pipe 210 is fixedly installed at the rear end of the fixed pipe 203a located on the rear side. The other end of water pipe 210 is fixedly connected to the rear wall of water tank 207. The interior of water tank 207 and the interior of collection box 205 are both connected to the interior of water pipe 210. With the above arrangement, water circulates in water tank 207 and hollow box 203 under the operation of delivery pump 209, continuously cooling hollow box 203. A mounting plate 205b is fixedly installed on the lower wall of the delivery pump 209. The mounting plate 205b is fixedly connected to the collection box 205. Support legs 206 are fixedly installed at the four corners of the lower wall of the collection box 205 and the water tank 207. The operation process of this embodiment is as follows: During distillation, the heating wire 107 is activated to heat the partition 106. At this time, the partition 106 conducts heat to the liquid inside the box 104. At the same time, the delivery pump 209 and the motor 201 are activated. Under the action of the delivery pump 209, the water in the water tank 207, which is cooled by ice, circulates in the hollow box 203 and the water tank 207. After the distillation temperature is reached, the motor 201 drives the vertical rod 201a to rotate, which causes the fan blade 202 to rotate. At this time, the steam passes through the delivery pipe 204 and enters the interior of the collection box 205 and acts on the hollow box 203. After the steam is cooled, it quickly liquefies and drips to the lower side of the inside of the collection box 205 to achieve the distillation effect.
