Description

Technical Field

[0001] This invention relates to the field of chemical reaction vessel technology, specifically to a chemical reaction vessel with a recyclable solution. Background Technology

[0002] In the field of chemical production, chemical reaction vessels are crucial equipment, as their performance directly affects the efficiency and quality of chemical reactions. Reactors are a commonly used type of reaction equipment in chemical plants, primarily using an electric motor to drive a stirring shaft to agitate reactants and ensure complete reaction to obtain the desired substances. However, existing chemical reaction vessels have limitations in terms of heat preservation, solution circulation, and mixing, making it difficult to meet the ever-increasing demands of chemical production.

[0003] Existing chemical reactors may not meet the demands for more efficient and precise mixing of solutions in complex reaction systems. Furthermore, some equipment struggles to deeply remove complex byproducts generated during cyclic operation, potentially leading to their accumulation and impacting reaction system stability and product quality. Additionally, achieving uniform and thorough mixing of solutions during cyclic control also affects reaction homogeneity and efficiency. Therefore, appropriate technical solutions need to be designed to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a chemical reaction vessel with a recyclable solution, thus solving its technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a chemical reactor for circulating solutions, comprising a chemical reactor and a solution circulation mechanism, wherein the chemical reactor is a modular assembly structure, and an upper heat insulation cover is fixedly provided on the upper exterior of the chemical reactor, and a lower heat insulation cover is fixedly provided on the lower exterior of the chemical reactor. A feed pipe is fixedly connected to the upper side of the chemical reactor through the upper heat insulation cover, and a discharge pipe is fixedly connected to the lower bottom of the chemical reactor through the lower heat insulation cover. An angle plate frame is fixedly distributed on the outer side wall of the lower heat insulation cover, a support plate is fixedly provided at the lower end of the angle plate frame, and a base is fixedly provided at the lower end of the support plate. The upper side of the chemical reactor is fixedly connected to the upper insulation cover, and the lower side of the chemical reactor is fixedly connected to the lower insulation cover. The solution circulation mechanism includes an inlet connection pipe and an outlet connection pipe. The inlet connection pipe is installed at the outer end of the lower connection pipe via a flange, and the outlet connection pipe is in the shape of an inverted J and is installed at the outer end of the inlet connection pipe via a flange.

[0006] Preferably, an inner insulation layer is fixedly provided at the lower outer end of the chemical reactor. The inner insulation layer is located inside the lower insulation cover, and the inner insulation layer and the lower insulation cover form a double-layer insulation structure. A pressure gauge is installed through the outer side of the upper insulation cover, and a temperature gauge is installed through the outer side of the lower insulation cover. The double-layer insulation structure formed by the inner insulation layer and the lower insulation cover can more effectively reduce heat loss. In the chemical reaction process, many reactions need to be carried out under specific temperature conditions. Temperature stability is crucial for the smooth progress of the reaction and the quality of the product. The double-layer insulation structure can better maintain a constant temperature inside the reactor, reduce energy consumption caused by heat loss, and lower production costs. At the same time, a stable temperature environment is also conducive to improving the selectivity and yield of the reaction, ensuring product quality. The pressure gauge and temperature gauge allow operators to monitor the pressure and temperature inside the reactor in real time, adjust the reaction conditions in a timely manner, and ensure the safe and stable progress of the reaction.

An inner partition is fixedly distributed on the inner wall of the chemical reactor. The sleeve serves to protect the drive shaft, the drive motor provides power, and the speed is adjusted by the reducer, causing the drive shaft to drive the stirring blades. The appropriate rotation speed and the distribution of the stirring blades can fully stir the solution in the reactor, ensuring thorough mixing of reactants, accelerating the reaction rate, improving conversion and selectivity, and reducing side reactions. The internal baffles are used to change the flow state of the solution in the reactor, increasing the degree of turbulence, further promoting the mixing and reaction of reactants, and acting as a separator and barrier to prevent the formation of vortices and dead zones during stirring. This ensures uniform reaction conditions throughout the reactor, improving reaction efficiency and product quality, and reducing product differences caused by uneven reaction.

[0008] Preferably, the solution circulation mechanism further includes a circulating liquid pump, a preliminary purification tank, a circulating liquid tank, and a solution mixing tank.

[0010] Preferably, the upper end of the inlet connecting pipe is connected to the upper side of the circulating liquid tank, and a support frame is fixedly provided at the bottom of the circulating liquid tank, which is fixedly located at the upper end of the base.

The upper end of the inlet connecting pipe passes through the circulating liquid tank and connects to the positioning box, and liquid equalization pipes are fixedly distributed at the bottom of the positioning box. The support frame is used to fix and support the circulating liquid tank to the upper end of the base, which can make the solution entering the positioning box evenly distributed, avoid local accumulation of solution in the circulating liquid tank, and ensure the uniformity and stability of the circulating solution. At the same time, the setting of the liquid equalization pipe is also conducive to improving the circulation efficiency of the solution and reducing energy consumption.

[0011] Preferably, a fixed connecting pipe is connected through the upper side of the circulating liquid tank, and a transfer connecting pipe is fixedly connected to the side end of the fixed connecting pipe. The upper end of the transfer connecting pipe is connected through the side of the solution mixing tank.

Both the shaft seats and the fixed horizontal pipe are hollow tubes, and spray pipes are fixedly connected to the bottom of the fixed horizontal pipe.

The circulating solution enters the solution mixing tank in the form of spraying through the spray pipe, increasing the dispersion of the solution and the contact area with other solutions in the tank, thus achieving more efficient mixing.

[0012] Preferably, a fixing column is fixed between the circulating liquid tank and the solution mixing tank; a fixing gear is fixed to the outer side of the fixing horizontal tube, a drive gear is meshed with the front end of the fixing gear, a drive shaft is fixed to the side end of the drive gear, a shaft cylinder is rotatably connected to the outer end of the drive shaft, the shaft cylinder is fixedly installed to the side end of the solution mixing tank, a control motor is connected to the outer end of the drive shaft, and a support is fixed to the bottom of the control motor and the side end of the solution mixing tank; the fixing column is used to fix and support the solution mixing tank at the upper end of the circulating liquid tank, the support is used to fix and support the control motor, the shaft cylinder is used to rotatably support the drive shaft, the control motor and the drive shaft are used to drive the control drive gear to rotate, the drive gear meshes with and controls the rotation of the fixing gear, the angle of the fixing horizontal tube can be finely adjusted in both directions, and the drive gear drives the fixing horizontal tube to rotate slightly under the drive of the control motor, further enhancing the mixing effect of the solution.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the upper and lower heat insulation covers, as well as the feeding pipe and the discharging pipe above and below the chemical reactor, the feeding and discharging are ensured to proceed smoothly, heat loss is minimized, and the safe and stable reaction is ensured. Furthermore, by setting the mixing control structure in the middle of the chemical reactor, the solution can be fully stirred to ensure that the reactants are fully mixed and the reaction rate is accelerated. By using a solution circulation mechanism connected to the outer ends of the upper and lower connecting pipes, the reaction solution is initially purified and then circulated by a pump. The solution is then evenly sprayed and mixed through a circulating liquid tank and a solution mixing tank. This ensures that the reaction solution is continuously circulated and renewed during the reaction process, promptly removing byproducts generated during the reaction and maintaining the stability of the reaction system. At the same time, the thorough mixing of the solution during circulation also helps to improve the uniformity and efficiency of the reaction. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-12This invention provides a technical solution: a chemical reactor with a recyclable solution, comprising a chemical reactor 1 and a solution circulation mechanism 2.

The structure and parameters of each part can be flexibly adjusted according to actual production needs, improving the versatility and adaptability of the equipment, greatly shortening maintenance time, reducing maintenance costs, and improving production efficiency. Furthermore, an upper insulation cover 11 is fixedly installed on the upper external part of the chemical reactor 1.

A base 14 is fixedly provided at the lower end of the support plate 1211. This can ensure the stability and safety of the entire equipment during operation and reduce the failures and safety hazards caused by equipment vibration. An upper connecting pipe 112 is fixedly connected to the upper side of the chemical reactor 1 through the upper insulation cover 11, and a lower connecting pipe 19 is fixedly connected to the lower side of the chemical reactor 1 through the lower insulation cover 12.

The inner insulation layer 122 is located inside the lower insulation cover 12, and the inner insulation layer 122 and the lower insulation cover 12 form a double-layer insulation structure. A pressure gauge 17 is installed through the exterior of the upper insulation cover 11, and a temperature gauge 18 is installed through the exterior of the lower insulation cover 12. The inner insulation layer 122 and the lower insulation cover 12 form a double-layer insulation structure, which can more effectively reduce heat loss. In chemical reaction processes, many reactions need to be carried out under specific temperature conditions. Temperature stability is crucial for the smooth progress of the reaction and the quality of the product. The double-layer insulation structure can better maintain a constant temperature inside the reactor, reduce energy consumption caused by heat loss, and lower production costs. At the same time, a stable temperature environment is also conducive to improving the selectivity and yield of the reaction, ensuring product quality. The pressure gauge 17 and temperature gauge 18 allow operators to monitor the pressure and temperature inside the reactor in real time, adjust the reaction conditions in a timely manner, and ensure the safe and stable progress of the reaction.

[0019] In a further improvement, a sleeve 15 is installed at the middle of the upper end of the chemical reactor 1, a reducer 161 is installed at the upper end of the sleeve 15, a drive motor 16 is installed above the reducer 161, and a drive shaft 162 is connected to the bottom of the reducer 161.

The distribution of the stirring blades 164 can fully stir the solution in the reactor, so that the reactants are fully mixed, the reaction rate is accelerated, the conversion rate and selectivity of the reaction are improved, and the occurrence of side reactions is reduced. The inner baffle 10 is used to change the flow state of the solution in the reactor, increase the turbulence of the solution, further promote the mixing and reaction of the reactants, and play a role in dispersing and blocking, preventing the formation of vortices and dead zones in the solution during stirring, ensuring that the reaction conditions are uniform throughout the reactor, improving the reaction efficiency and product quality, and reducing product differences caused by uneven reaction.

[0020] Further improvements include a circulating pump 21, a preliminary purification tank 22, a circulating liquid tank 23, and a solution mixing tank 24.

The connecting plate 201 is used to fix the circulating liquid pump 21 to the outer end of the support plate 1211. The circulating liquid pump 21 is used to draw pumped liquid through the liquid extraction pipe 211 and the liquid pumping pipe 212. The liquid inlet connecting pipe 221 and the transfer pipe 222 respectively control the inlet and outlet of the preliminary purification box 22.

[0021] Further improvements include a sealing cover 220 installed on the top of the preliminary purification box 22, an end plate 2201 fixedly installed at the bottom center of the sealing cover 220, and filter plate one 2202, filter plate two 2203 and filter plate three 2204 fixedly connected to the bottom of the end plate 2201. Filter plate one 2202, filter plate two 2203 and filter plate three 2204 are S-shaped and fixedly connected as one unit. The multi-layer S-shaped filter plate design increases the contact area and contact time between the solution and filter plates 2202, 2203, and 2204, buffering the flow and more effectively filtering out impurities and solid particles in the solution, improving the purity of the solution and ensuring the smooth progress of the reaction.

[0022] In a further improvement, the upper end of the liquid inlet connection pipe 221 is connected to the upper side of the circulating liquid tank 23, and a support frame 231 is fixedly provided at the bottom of the circulating liquid tank 23, and the support frame 231 is fixedly provided at the upper end of the base 14.

Both the bearing seats 2422 and the fixed horizontal tube 242 are hollow tubes, and spray pipes 2421 are fixedly connected to the bottom of the fixed horizontal tube 242. The fixed connecting pipe 25 and the transfer connecting pipe 251 are used to transfer the solution from the upper end of the circulating liquid tank 23 to the side of the solution mixing tank 24, and flow to the spray pipe 2421 through the hollow tube structure bearing 2422 and the fixed horizontal pipe 242. The circulating solution enters the solution mixing tank 24 in the form of spray through the spray pipe 2421, which increases the degree of dispersion of the solution and the contact area with other solutions in the tank, and achieves more efficient mixing.

[0024] Specifically, a fixing column 26 is fixedly provided between the circulating liquid tank 23 and the solution mixing tank 24; A fixed gear plate 243 is fixedly provided on the outer side of the fixed horizontal tube 242.

A shaft cylinder 2443 is rotatably connected through the outer end of the drive shaft 2441. The shaft cylinder 2443 is fixedly provided through the side end of the solution mixing tank 24. A control motor 2442 is connected to the outer end of the drive shaft 2441. A support 2444 is fixedly provided at the bottom of the control motor 2442 and the side end of the solution mixing tank 24. The fixed column 26 is used to fix and support the solution mixing tank 24 at the upper end of the circulating liquid tank 23. The support 2444 is used to fix and support the control motor 2442. The shaft cylinder 2443 is used to rotate and support the drive shaft 2441. The control motor 2442 and the drive shaft 2441 are used to drive the control drive gear 244 to rotate. The drive gear 244 meshes with and controls the fixed gear plate 243 to rotate. The angle of the fixed horizontal tube 242 can be finely adjusted in both directions. Under the drive of the control motor 2442, the drive gear 244 drives the fixed horizontal tube 242 to rotate slightly, which further enhances the mixing effect of the solution.

[0026] Working principle: The solution to be reacted is poured in through the feed pipe 111, while the discharge pipe 13 is in the closed state; The automatic control system starts the drive motor 16 and reducer 161 to rotate the drive shaft 162, which drives multiple sets of fixed rings 163 and stirring blades 164 to mix and stir the solution. The circulating liquid pump 21 is started, and the liquid is drawn through the liquid drawing pipe 211. The reaction solution is drawn from the lower connecting pipe 19. The drawn solution enters the preliminary purification tank 22 through the liquid inlet connecting pipe 221. The solution flows through the S-shaped and integrated filter plates 2202, 2203 and 2204 in sequence. Through multi-layer filtration, impurities and solid particles in the solution are filtered out, the purity of the solution is improved, the by-products generated by the reaction are removed in time, and the stability of the reaction system is maintained. After preliminary purification, the solution enters the positioning box 232 in the circulating liquid tank 23 through the transfer pipe 222, the extraction pipe 211, and the pump pipe 212. Then, it is evenly distributed into the circulating liquid tank 23 through the equalization pipe 2321 at the bottom of the positioning box 232 to avoid local accumulation of solution and ensure that the circulating solution is uniform and stable. The solution in the circulating liquid tank 23 is transferred to the side of the solution mixing tank 24 through the fixed connecting pipe 25 and the transfer connecting pipe 251. It enters the hollow tube structure of the bearing 2422 and the fixed horizontal pipe 242. The control motor 2442 is started, and the drive shaft 2441 drives the drive gear 244 to rotate. The drive gear 244 meshes with and controls the rotation of the fixed gear plate 243. The angle of the fixed horizontal pipe 242 can be finely adjusted in both directions to further enhance the solution mixing effect. The solution enters the solution mixing tank 24 from the spray pipe 2421 at the bottom of the fixed horizontal pipe 242 in the form of spray, which increases the degree of solution dispersion and contact area, and achieves efficient mixing. The mixed solution flows back to the upper connecting pipe 112 of the chemical reactor 1 through the liquid outlet connecting pipe 241, and re-enters the reactor to participate in the reaction, thereby realizing solution circulation and improving reaction uniformity and efficiency.
