Description

Technical Field

[0001] The present invention relates to the technical field of water-cooling equipment, and particularly to a water-cooling equipment for preparing aromatic boronic acid intermediate materials. Background Art

[0002] Aromatic boronic acid compounds have important application values in the fields of organic synthesis, drug research and development, and materials science. With the continuous development of related fields, the demand for aromatic boronic acid intermediate materials is increasing day by day.

[0003] Currently, for the water-cooling equipment for preparing aromatic boronic acid intermediate materials, it is found that there are at least the following technical problems:

[0004] First, the cooling methods of the existing water-cooling equipment for preparing aromatic boronic acid intermediate materials, such as direct water spraying or ordinary jacket cooling, often have problems of uneven cooling and low efficiency, and it is difficult to meet the temperature control requirements in the preparation of aromatic boronic acid intermediate materials;

[0005] Second, the existing water-cooling equipment for preparing aromatic boronic acid intermediate materials cannot fully contact with the reaction equipment, resulting in poor heat transfer and affecting the cooling effect. At the same time, after long-term operation, the heat dissipation components are prone to accumulate dust and dirt, which not only hinders heat dissipation but also increases the operation burden and energy consumption of the equipment;

[0006] Third, in addition, when the existing cooling equipment deals with a large amount of heat rapidly generated during the preparation of aromatic boronic acid intermediate materials, it cannot timely and effectively discharge the heat, thus affecting the stability of the reaction and the consistency of the products.

Blocks are fixedly connected to both the upper and lower ends of the spiral blade, and the two blocks are respectively fixedly connected to the side wall of the circular sleeve and the inner side of the fixed ring. A water inlet pipe and a water outlet pipe respectively penetrate through the upper and lower sides of the inner cavity of the circular sleeve, and both the water inlet pipe and the water outlet pipe are connected to a water tank through pipelines. A plurality of heat dissipation fins are fixedly installed at equal intervals on the outer circumference of the circular sleeve. A heat discharge port is fixedly connected to the upper part of the side end of the reaction device main body.

[0012] Preferably: A fixing plate is fixedly installed at the upper end of the reaction device main body. A motor is fixedly installed on the fixing plate. The output shaft of the motor is fixedly connected to a first rotating shaft. A first bevel gear is fixedly installed on the first rotating shaft. A gear is fixedly connected to the bottom end of the first rotating shaft. A second rotating shaft is rotatably installed in the heat discharge port. A second bevel gear is fixedly installed on the second rotating shaft. The second bevel gear meshes with the first bevel gear. A fan blade is fixedly installed on the second rotating shaft. The fan blade is located in the heat discharge port and is used to discharge the heat in the inner cavity of the reaction device main body.

[0013] Preferably: Rotating rings are movably sleeved on both the upper and lower sides of the circular sleeve. A toothed ring is fixedly installed on the upper rotating ring. The gear meshes with the toothed ring. An annular groove is formed in the side wall of each rotating ring. A limiting ring is rotatably installed in each annular groove. Each limiting ring is fixedly sleeved on the outer end of the reaction device main body.

[0014] Preferably: Vertical plates are arranged on the outer sides of the two rotating rings. Three heat dissipation fans are arranged in the vertical plates. Fixed ear plates are fixedly connected to both the upper and lower ends of each vertical plate. Each fixed ear plate is respectively fixedly connected to each rotating ring.

The water inlet pipe and the water outlet pipe are both designed in a hook shape, and one end of each water inlet pipe and water outlet pipe is communicated with the baffle block respectively.

[0016] (III) Beneficial effects

[0017] First: Through the flow of cooling water in the spiral channel, uniform and continuous cooling of the reaction process is achieved, accurately controlling the temperature of the main body of the reaction equipment, ensuring the smooth progress of the reaction and the product quality. The setting of the heat dissipation fins greatly increases the contact area with the air, further improving the heat dissipation efficiency and maintaining the efficient operation of the cooling system. The fan blades driven by the motor, the rotating vertical plate and the heat dissipation fan effectively discharge the heat in the inner cavity of the reaction equipment, making the air flow faster and more evenly, enhancing the overall heat dissipation effect, ensuring the stability of the reaction. The adjustable cleaning brush can comprehensively clean the heat dissipation fins as needed, avoiding dust accumulation affecting heat dissipation, while reducing friction and resistance when not in need of cleaning, ensuring the stable and low-energy consumption operation of the equipment, prolonging the service life of components, improving the stability and reliability of the entire water-cooled equipment, and effectively meeting the strict requirements for efficient cooling in the preparation process of aromatic boronic acid intermediate materials.

[0018] Second: When the circulating water pump starts, the cooling water in the water tank flows in the spiral channel along the direction of the spiral of the spiral blade. During the flow, the cooling water fully contacts the outer wall of the main body of the reaction equipment, absorbs the heat on the main body of the reaction equipment, and reduces the temperature of the main body of the reaction equipment. The cooling water that has absorbed the heat flows back to the water tank through the water outlet pipe at the other end of the spiral channel, completing a cooling cycle. Through the flow of cooling water in the spiral channel, uniform and continuous cooling of the reaction process for the preparation of aromatic boronic acid intermediate materials is achieved, accurately controlling the temperature inside the main body of the reaction equipment, and ensuring the smooth progress of the reaction and the product quality.

[0019] Third: A number of heat dissipation fins are fixedly installed at equal intervals on the circumferential outer end of the circular housing, greatly increasing the contact area between the circular housing and the air. When the circular housing that has absorbed the reaction heat contacts the air, the heat can be quickly transferred from the heat dissipation fins to the surrounding air, thereby further improving the heat dissipation efficiency. The setting of the heat dissipation fins significantly enhances the heat dissipation ability of the circular housing, accelerates the dissipation of heat, and helps to maintain the efficient operation of the entire cooling system during the preparation process of aromatic boronic acid intermediate materials.

[0020] IV: By starting the motor, the first rotating shaft rotates. The rotation of the first rotating shaft drives the first bevel gear and the gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate. The rotation of the second bevel gear drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the fan blades to rotate. The fan blades rotate within the heat discharge outlet, generating a strong airflow that rapidly discharges the heat generated during the preparation of the aromatic boronic acid intermediate material in the inner cavity of the reaction equipment main body, reducing the temperature inside the reaction equipment main body, enhancing the overall heat dissipation effect, and ensuring the stable progress of the reaction for preparing the aromatic boronic acid intermediate material.

[0021] V: The rotation of the rotating ring drives the vertical plate to rotate, causing the vertical plate to rotate around the center of the reaction equipment main body. The cooling fan on the vertical plate starts, generating an airflow that blows towards the heat dissipation fins. The rotation of the vertical plate and the blowing of the cooling fan make the air flow around the heat dissipation fins faster and more evenly, further improving the heat dissipation efficiency of the heat dissipation fins in the water-cooling equipment for preparing the aromatic boronic acid intermediate material, and enhancing the heat dissipation performance of the entire cooling system during the preparation of the aromatic boronic acid intermediate material.

[0022] VI: The movement of the vertical rod causes the cleaning brush to fit against the surface of the heat dissipation fins. As the vertical plate rotates, it drives the vertical rod and the cleaning brush to perform a circular motion, thereby enabling a comprehensive cleaning of the heat dissipation fins on the circular housing. When there is no need to clean the heat dissipation fins, the cleaning brush is not in contact with the surface of the heat dissipation fins, and the position of the cleaning brush can be flexibly adjusted according to actual needs. Effective cleaning can be achieved when cleaning is required, and unnecessary friction and resistance can be avoided when cleaning is not required, ensuring the smooth rotation of the vertical plate, maintaining a good heat dissipation effect, extending the service life of the cleaning brush and the heat dissipation fins, reducing the energy consumption of the equipment operation, and improving the stability and reliability of the entire water-cooling equipment.

One end of each water inlet pipe 22 and water outlet pipe 23 is respectively connected to the block 32. There is a water tank (not shown) on one side of the circular housing 2. A circulating water pump is provided on the water tank pipeline. A temperature sensor is provided inside the reaction equipment main body 11. The water inlet pipe 22 and the water outlet pipe 23 are connected to the water tank pipeline. During the preparation process of the aromatic ring boronic acid intermediate material, when heat is generated by the reaction and the temperature rises, it will cause the temperature on the surface of the reaction equipment main body 11 to rise. The circulating water pump starts to make the cooling water in the water tank flow in the spiral channel 31 along the spiral direction of the spiral blade 3. During the flow process, the cooling water fully contacts the outer wall of the reaction equipment main body 11, absorbs the heat on the reaction equipment main body 11, and reduces the temperature of the reaction equipment main body 11. The cooling water that has absorbed the heat flows back to the water tank through the water outlet pipe 23 at the other end of the spiral channel 31, completing a cooling cycle. Through the flow of the cooling water in the spiral channel 31, uniform and continuous cooling of the reaction process for preparing the aromatic ring boronic acid intermediate material is achieved, accurately controlling the temperature inside the reaction equipment main body 11, ensuring the smooth progress of the reaction and the product quality. A number of heat dissipation fins 24 are fixedly installed at equal intervals on the outer circumferential end of the circular housing 2, greatly increasing the contact area between the circular housing 2 and the air. When the circular housing 2 that has absorbed the reaction heat contacts the air, the heat can quickly be transferred from the heat dissipation fins 24 to the surrounding air, thereby further improving the heat dissipation efficiency. The setting of the heat dissipation fins 24 significantly enhances the heat dissipation ability of the circular housing 2, accelerates the dissipation of heat, and helps to maintain the efficient operation of the entire cooling system during the preparation process of the aromatic ring boronic acid intermediate material. By starting the motor 4, the rotating shaft one 41 rotates. The rotation of the rotating shaft one 41 drives the bevel gear one 42 and the gear 43 to rotate. The rotation of the bevel gear one 42 drives the bevel gear two 46 to rotate. The rotation of the bevel gear two 46 drives the rotating shaft two 44 to rotate. The rotation of the rotating shaft two 44 drives the fan blade 45 to rotate. The fan blade 45 rotates in the heat discharge port 15, generating a strong air flow, quickly discharging the heat generated inside the cavity of the reaction equipment main body 11 during the preparation process of the aromatic ring boronic acid intermediate material, reducing the temperature inside the reaction equipment main body 11, enhancing the overall heat dissipation effect, and ensuring the stable progress of the reaction for preparing the aromatic ring boronic acid intermediate material. Since the gear 43 meshes with the toothed ring 52, the rotation of the gear 43 will drive the toothed ring 52 to rotate. The rotation of the toothed ring 52 drives the upper rotating ring 5 to rotate. The rotation of the rotating ring 5 drives the vertical plate 6 to rotate, causing the vertical plate 6 to rotate around the center of the reaction equipment main body 11. The heat dissipation fan 61 on the vertical plate 6 starts, generating an air flow blowing towards the heat dissipation fins 24. The rotation of the vertical plate 6 and the blowing of the heat dissipation fan 61 make the air flow around the heat dissipation fins 24 faster and more uniform, further improving the heat dissipation efficiency of the heat dissipation fins 24 in the water-cooling equipment for preparing the aromatic ring boronic acid intermediate material.Enhanced the heat dissipation performance of the entire cooling system during the preparation process of aromatic boronic acid intermediate materials. When it is necessary to clean the dust on the surface of the heat dissipation fins 24, twist the torsion block 81 to rotate the screw rod 8. The rotation of the screw rod 8 drives the vertical rod 7 to move closer to the heat dissipation fins 24. The movement of the vertical rod 7 makes the cleaning brush 73 fit against the surface of the heat dissipation fins 24. As the vertical plate 6 rotates, it will drive the vertical rod 7 and the cleaning brush 73 to perform circular motion, so as to comprehensively clean the heat dissipation fins 24 on the circular housing 2. When it is not necessary to clean the heat dissipation fins 24, the cleaning brush 73 is not in contact with the surface of the heat dissipation fins 24, and the position of the cleaning brush 73 can be flexibly adjusted according to actual needs. Effective cleaning can be achieved when cleaning is required, and unnecessary friction and resistance can be avoided when cleaning is not required, ensuring the smooth rotation of the vertical plate 6, maintaining a good heat dissipation effect, extending the service life of the cleaning brush 73 and the heat dissipation fins 24, reducing the energy consumption of equipment operation, and improving the stability and reliability of the entire water-cooled equipment.

[0037] Working principle:

[0038] First step, a water tank (not shown) is provided on one side of the circular housing 2, a circulation water pump is provided on the water tank pipeline, a temperature sensor is provided inside the reaction equipment main body 11, and the water inlet pipe 22 and the water outlet pipe 23 are communicated with the water tank pipeline. During the preparation process of aromatic boronic acid intermediate materials, when the reaction generates heat and the temperature rises, the temperature on the surface of the reaction equipment main body 11 will rise. The circulation water pump is started to make the cooling water in the water tank flow in the spiral channel 31 along the spiral direction of the spiral blade 3. During the flow process, the cooling water fully contacts the outer wall of the reaction equipment main body 11, absorbs the heat on the reaction equipment main body 11, and reduces the temperature of the reaction equipment main body 11. The cooling water that has absorbed heat flows back to the water tank through the water outlet pipe 23 at the other end of the spiral channel 31, completing a cooling cycle. Through the flow of the cooling water in the spiral channel 31, uniform and continuous cooling of the reaction process of aromatic boronic acid intermediate materials is realized, accurately controlling the temperature inside the reaction equipment main body 11, and ensuring the smooth progress of the reaction and the product quality.

[0039] Second step, a number of heat dissipation fins 24 are fixedly installed at equal intervals on the outer circumferential end of the circular housing 2, greatly increasing the contact area between the circular housing 2 and the air. When the circular housing 2 that has absorbed the reaction heat contacts the air, the heat can quickly be transferred from the heat dissipation fins 24 to the surrounding air, thereby further improving the heat dissipation efficiency. The setting of the heat dissipation fins 24 significantly enhances the heat dissipation capacity of the circular housing 2, accelerates the dissipation of heat, and helps to maintain the efficient operation of the entire cooling system during the preparation process of aromatic boronic acid intermediate materials.

[0040] In the third step, by starting the motor 4, the first rotating shaft 41 rotates. The rotation of the first rotating shaft 41 drives the first bevel gear 42 and the gear 43 to rotate. The rotation of the first bevel gear 42 drives the second bevel gear 46 to rotate. The rotation of the second bevel gear 46 drives the second rotating shaft 44 to rotate. The rotation of the second rotating shaft 44 drives the fan blade 45 to rotate. The fan blade 45 rotates in the heat discharge port 15, generating a strong air flow, quickly discharging the heat generated in the inner cavity of the reaction equipment main body 11 during the preparation of the aromatic boronic acid intermediate material, reducing the temperature inside the reaction equipment main body 11, enhancing the overall heat dissipation effect, and ensuring the stable progress of the reaction for preparing the aromatic boronic acid intermediate material.

[0041] In the fourth step, since the gear 43 meshes with the toothed ring 52, the rotation of the gear 43 drives the toothed ring 52 to rotate. The rotation of the toothed ring 52 drives the upper rotating ring 5 to rotate. The rotation of the rotating ring 5 drives the vertical plate 6 to rotate, causing the vertical plate 6 to rotate around the center of the reaction equipment main body 11. The heat dissipation fan 61 on the vertical plate 6 starts, generating an air flow blowing towards the heat dissipation fins 24. The rotation of the vertical plate 6 and the blowing of the heat dissipation fan 61 make the air flow around the heat dissipation fins 24 faster and more uniform, further improving the heat dissipation efficiency of the heat dissipation fins 24 in the water-cooling equipment for preparing the aromatic boronic acid intermediate material, and enhancing the heat dissipation performance of the entire cooling system during the preparation of the aromatic boronic acid intermediate material.

[0042] In the fifth step, when it is necessary to clean the dust on the surface of the heat dissipation fins 24, twist the knob 81 to make the screw rod 8 rotate. The rotation of the screw rod 8 drives the vertical rod 7 to move closer to the heat dissipation fins 24. The movement of the vertical rod 7 makes the cleaning brush 73 fit the surface of the heat dissipation fins 24. As the vertical plate 6 rotates, it drives the vertical rod 7 and the cleaning brush 73 to perform a circular motion, so as to be able to comprehensively clean the heat dissipation fins 24 on the circular housing 2. When it is not necessary to clean the heat dissipation fins 24, the cleaning brush 73 is not made to fit the surface of the heat dissipation fins 24, and the position of the cleaning brush 73 can be flexibly adjusted according to actual needs, achieving effective cleaning when needed, avoiding unnecessary friction and resistance when not needed, ensuring the smooth rotation of the vertical plate 6, maintaining a good heat dissipation effect, prolonging the service life of the cleaning brush 73 and the heat dissipation fins 24, reducing the energy consumption of the equipment operation, and improving the stability and reliability of the entire water-cooling equipment.

[0043] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
