Description

Technical Field

[0001] The invention relates to the technical field of reaction tools, in particular to a catalytic reaction device for preparing diethyl carbonate. Background Art

[0002] Diethyl carbonate is a colorless liquid organic compound with the chemical formula C5H10O3. It is mainly used as an intermediate in organic synthesis and drug synthesis, and can also be used as a solvent. Due to its high energy density and low volatility, diethyl carbonate is a candidate for lithium-ion battery electrolyte. When preparing and producing diethyl carbonate, diethyl carbonate and various ingredients need to be added to the inside of the catalytic reaction device. After ethylene glycol, carbon dioxide and the catalyst are mixed, they are heated and the pressure is increased to react to generate diethyl carbonate. The diethyl carbonate reactor drives the agitator through a driving device to fully mix the reactants in the reaction tank. The design of the agitator allows the reactants to be heated evenly, thereby improving production efficiency and product quality. In addition, the sealing design of the reactor ensures the safety of the reaction process. The catalytic reaction device commonly used in the market for preparing diethyl carbonate needs to be ventilated to discharge the exhaust gas before preparation. However, the ventilation speed inside the device is slow, and during the preparation process, some materials are easy to remain on the inner wall of the device, which requires a scraping structure to clean. However, the scraping structure is prone to wear after continuous use, which will affect the scraping efficiency in the later stage. When the material is discharged, some lumps are easy to block the outlet, affecting the discharge efficiency. Summary of the invention

[0005] In at least some embodiments, a top cover is fixed on the top of the device body, and a motor is fixedly installed on the top of the top cover. The motor is connected to the rotating shaft component and drives the rotating shaft component to rotate. A connecting pipe and a feeding port are provided on the top of the device body, and a heating tube is fixed inside the partition of the device body; a cross-shaped support block is fixed on the inner side of the bottom end of the side tube assembly, and a sliding rod component is inserted through the inside of the support block. The sliding rod component with an L-shaped structure at the top is a T-shaped axis structure at the bottom end, and a spring is sleeved on the outside of the sliding rod component. The sliding rod component is freely pulled and pulled inside the support block, and a spring is sleeved on the outside of the bottom end of the sliding rod component. The inner end of the sliding rod component is fixedly connected to the sealing plate assembly, and the outer end of the spring contacts the side of the support block; a funnel-shaped guide is fixed on the top of the side tube assembly, and the bottom of the guide is fixedly connected to the top of the top cover through a connecting block, and a fan is fixed to the top of the guide by bolts and nuts.

[0006] In at least some embodiments, an installation groove is provided inside the bottom piece structure, a discharge pipe is provided at the bottom of the bottom piece structure, a fixed structure is installed inside the installation groove through a thread, and the top of the fixed structure is internally an inclined structure; an auxiliary part is fixed at the middle position of the top of the fixed structure, an inclined through groove is provided at the outer bottom end of the auxiliary part, and the bottom end of the through groove passes through the fixed structure; a support rod structure is welded and fixed to the top end of the auxiliary part, the top end of the support rod structure is welded and fixed to the top rod structure, and the outside of the support rod structure is provided with auxiliary grooves that are evenly arranged in a ring shape.

[0007] In at least some embodiments, two groups of stirring components are welded and fixed to the outside of the rotating shaft component, and two external parts are welded to the outside of the rotating shaft component, and the external parts are composed of a circular ring and three support plates; a pull-out groove is provided on the outside of the external part, and a vertical groove is provided through the inside of the external part, and the inside of the vertical groove is connected with the inside of the pull-out groove; a freely pullable splicing plate component is inserted into the inside of the pull-out groove, and the top of the force groove coincides with the top of the vertical groove, and a round rod is inserted into the overlapping position, and the round rod is fixed to the top of the counterweight, and the counterweight is a lead block with a cylindrical structure.

[0008] The present invention provides a catalytic reaction device for preparing diethyl carbonate, which has the following beneficial effects: When it is necessary to prepare diethyl carbonate, the feeding port of the device body can be controlled to open in advance, and then the fan can be controlled to generate wind force, and the air can be controlled to pass through the side pipe assembly, so that the sealing plate assembly can be pushed to move by the wind pressure, and the spring outside the sliding rod component can be squeezed to discharge the air from the lower part of the inner part of the device body, and the exhaust gas can be controlled to flow upward and be discharged quickly, thereby improving the exhaust gas discharge efficiency, achieving rapid ventilation, and improving the preparation efficiency of diethyl carbonate.

At the same time, the scraper component is continuously subjected to force to fit the inner wall of the device body to prevent the material from sticking to the inner wall of the device body. When the scraper component continues to fit and wear and gaps occur, the counterweight drives the round rod to move downward by its own weight, so that the round rod is displaced inside the force groove and the vertical groove at the same time. Since the force groove has an inclined structure, it generates a force displacement that pushes the splicing plate component and the scraper component, so that the scraper component uses the moving force and rotational swinging momentum to ensure that the scraper component is always in contact with the inner wall of the device body, thereby ensuring the scraping efficiency after wear.

[0010] When the material is discharged, it flows downward with the help of gravity, and is discharged downward through the top of the enclosure, the side of the top rod structure, the through slot and the auxiliary slot in turn. If lumps are generated in the material, the lumps fall on the top of the top rod structure. Since the top rod structure is inclined, it controls the lumps to move to the outside of the enclosure and blocks the lumps. The material is discharged downward through the top rod structure to avoid blockage of the downward flow. Then the narrow through slot and the auxiliary slot block the larger lumps again, so that the material can be discharged smoothly and avoid lumps blocking the discharge of the material.

The outer part 302 is composed of a circular ring and three support plates, which respectively support three splicing plate components 305 for use; a pull-out groove 303 is opened on the outside of the outer part 302, and a convex block is provided on the side of the splicing plate component 305, which is embedded in the side of the pull-out groove 303 to guide the pull-out, and a vertical groove 303 is opened inside the outer part 302 4.

[0020] The working principle of this embodiment is as follows: when it is necessary to prepare the catalytic reaction of diethyl carbonate, first control the opening of the feed port, and then control the operation of the fan 108. The fan 108 controls the wind to pass through the guide 107 and the side pipe assembly 103, and uses the wind pressure to push the sealing plate assembly 105 to be displaced, push the sliding rod assembly 106 to be displaced, compress the spring, and allow the wind to be discharged through the bottom end of the side pipe assembly 103. The wind flows upward from the bottom end of the inner part of the device body 1, promoting the rapid circulation of exhaust gas, improving the ventilation effect, avoiding the generation of residual exhaust gas, and eliminating safety hazards. Then, the raw materials and various ingredients are added to the interior of the device body 1, and the motor is controlled to operate and heat the materials at the same time. The motor drives the rotating shaft component 3 to rotate. When rotating, the rotating shaft component 3 drives the stirring component 301 and the outer component 302 to rotate together. When rotating, the scraper component 307 is continuously subjected to force and is in contact with the device body 1. The inner wall contacts and scrapes off the residue to improve the cleaning efficiency. At the same time, when the outer end of the scraper component 307 is worn, the counterweight 308 uses gravity to move the round rod downward inside the vertical groove 304 and the force groove 306, pushing the splicing plate component 305 and the scraper component 307 to move outward. At the same time, with the help of the swinging force, the scraper component 307 is continuously stressed and fits with the inner wall of the device body 1 to ensure the scraping efficiency. After the preparation of diethyl carbonate is completed, the discharge of diethyl carbonate is controlled. If agglomerates are generated in diethyl carbonate, the agglomerates fall on the top of the top rod structure 204, and the agglomerates are controlled to flow and move to the outside of the enclosure 203, so that the enclosure 203 blocks the agglomerates, and diethyl carbonate will be guided to flow through the top rod structure 204, the through groove 206 and the auxiliary groove 208, so that diethyl carbonate can be discharged smoothly, avoiding agglomerations affecting the flow efficiency of diethyl carbonate.
