Description

Technical Field

[0001] This utility model relates to the field of chemical cooling liquid technology, and in particular to a production device for cooling chemical mixtures. Background Technology

[0002] Chemical mixtures are homogeneous or heterogeneous systems formed by mixing two or more substances (including liquids, solid particles, gases, etc.) during chemical production. Many chemical reactions during the production of chemical mixtures are accompanied by the release of a large amount of heat. If the temperature of the mixture is too high, it may lead to uncontrolled reaction. Therefore, cooling devices are needed to cool the chemical mixtures.

[0003] Currently, common cooling methods typically involve installing jackets on the outer walls of containers such as reactors and storage tanks. Cooling media flow within the jackets to cool the chemical mixture inside the containers. The contact area between the jacket and the outer wall of the reactor is usually a flat or simple curved surface. The flow of the cooling media within the jackets is mostly unidirectional or low-turbulence laminar flow. The heat exchange area with the reactor wall is limited, and the heat transfer coefficient is low. Moreover, the heat absorbed by the cooling media (such as cold water) within the jackets is mainly dissipated naturally through the outer wall of the jackets, resulting in low heat dissipation efficiency and significant influence from ambient temperature. If continuous cooling is required, the cooling media must be constantly replaced, increasing energy consumption and operating costs. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a production device for cooling chemical mixtures, in order to solve the shortcomings of existing chemical mixture cooling devices which have poor cooling effects.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a production device for cooling chemical mixtures, including a reaction vessel;

[0006] The reactor is provided with a cooling chamber on the outside and a cooling pipe inside the cooling chamber. The cooling pipe is wound around the outer wall of the reactor. The reactor is provided with a stirring mechanism inside and the stirring mechanism includes a stirring shaft located at the center of the reactor. Stirring blades are evenly distributed on the stirring shaft.

[0007] The cooling chamber outside the reactor is equipped with heat dissipation mechanisms on both sides. Each heat dissipation mechanism includes a cooling fan located at the center of both sides of the cooling chamber. Each cooling fan has a driven gear on its drive shaft, and each driven gear meshes with a driving gear. The top of each driving gear is equipped with a second synchronous pulley via a transmission shaft. The heat dissipation mechanism also includes two sets of first synchronous pulleys located at the top of the stirring shaft. The first and second synchronous pulleys are connected by a synchronous belt.

[0008] Preferably, the reactor has a feed inlet at one end of its top and a discharge outlet at its bottom.

[0009] The above structure enables convenient addition of chemical mixtures and smooth discharge of cooled products. The inlet is located at the top to facilitate gravity flow of materials, while the outlet is located at the bottom to utilize gravity to assist discharge and reduce material residue.

[0010] Preferably, an inlet and an outlet are respectively provided at both ends of one side of the cooling chamber, and the inlet and outlet are respectively connected to both ends of the cooling pipe.

[0011] The above structure enables continuous circulation of the cooling medium within the cooling pipe. The inlet introduces the low-temperature medium, while the outlet discharges the high-temperature medium after heat absorption, ensuring that the cooling pipe can continuously absorb heat from the reactor and maintain stable cooling capacity.

[0012] Preferably, the cooling pipe is fixed to the outer wall of the reactor in a spiral shape, and the cooling pipe is made of copper alloy. The inner wall of the cooling pipe has evenly distributed ridges, and the cross-section of the ridges is semi-circular.

[0013] Through the above structure, the spiral design increases the contact area between the cooling pipe and the reactor, and extends the flow path of the cooling medium; the copper alloy material utilizes its high thermal conductivity to accelerate heat transfer, and the semi-circular convex ridges on the inner wall can disturb the flow of the medium to form turbulence, break the boundary layer, and further improve the heat transfer efficiency. The three factors work together to enhance the heat absorption capacity of the cooling pipe.

[0014] Preferably, the first and second synchronous pulleys have the same diameter, and their central axes are on the same horizontal plane. The synchronous belts are all horizontally tensioned, and the outer periphery of the first and second synchronous pulleys and the inner wall of the synchronous belts are provided with matching toothed structures.

[0015] The above structure ensures that the stirring shaft and the drive shaft rotate at the same speed. The horizontal collinear design and the tensioned synchronous belt prevent deviation or slippage during transmission. The matching tooth structure achieves zero-slip transmission and ensures the synchronization of the cooling fan and the stirring mechanism.

[0016] Preferably, the cooling fans are symmetrically distributed about the left and right sides of the cooling cavity, and the cooling cavity is made of aluminum alloy.

[0017] The above structure enables uniform heat dissipation from the cooling pipes within the cooling chamber, avoiding uneven local heat dissipation. The aluminum alloy material combines excellent thermal conductivity with lightweight characteristics, improving overall heat dissipation efficiency.

[0018] Preferably, the stirring mechanism further includes a drive motor disposed at the top of the reactor, and the output end of the drive motor is connected to the stirring shaft, wherein the bottom end of the stirring shaft is uniformly provided with spiral blades.

[0019] Through the above structure, the drive motor provides stable power to the stirring shaft, and the stirring blades can perform targeted stirring of the mixture at the bottom of the reactor to avoid the material from settling at the bottom of the reactor and forming a "dead zone". In conjunction with the upper stirring blades, the mixture in the entire reactor is uniformly stirred, which enhances the overall heat transfer efficiency and makes the mixture cool uniformly as a whole.

[0020] The present invention provides a production device for cooling chemical mixtures, the advantages of which are:

[0021] The system incorporates a reaction vessel, cooling chamber, cooling pipe heat dissipation mechanism, and stirring mechanism. The cooling pipes are spirally wound around the outer wall of the reaction vessel, increasing the contact area with the vessel body. The spiral structure guides the flow rate and direction of the cooling water, enhancing turbulence and improving the heat transfer coefficient. The drive motor rotates the stirring shaft and stirring blades, generating strong shearing and pushing forces on the chemical mixture, forcibly breaking the boundary layer and creating intense turbulence or eddies within the vessel. The high-temperature liquid is rapidly brought to the vicinity of the vessel wall, directly contacting the cooled vessel wall for cooling. Simultaneously, the rotation of the stirring shaft causes the first synchronous pulley to rotate, which in turn drives the second synchronous pulley via a synchronous belt. This, in turn, drives the drive shaft and the drive gear. The drive shaft of the cooling fan is equipped with a driven gear that meshes with the drive gear. Therefore, the rotation of the cooling fan provides forced air cooling of the cooling pipes and cooling medium, accelerating heat diffusion to the environment. Even with changes in ambient temperature, it maintains stable heat dissipation capacity and eliminates the need for frequent cooling medium replacement, resulting in greater energy savings. Only one drive motor is needed to simultaneously drive the stirring blades and cooling fan, reducing the number of power units, simplifying the equipment structure and control system, thereby reducing energy consumption and maintenance costs.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 The present invention provides a production device for cooling chemical mixtures, comprising a reaction vessel 1;

[0030] Please see Figures 1-3 A cooling chamber 2 is provided on the outside of the reactor 1, and a cooling pipe 5 is provided inside the cooling chamber 2. The cooling pipe 5 is wound around the outer wall of the reactor 1. A feed inlet 10 is provided at one end of the top of the reactor 1, and a discharge outlet 8 is provided at the bottom of the reactor 1. A water inlet 6 and a water outlet 7 are provided at both ends of one side of the cooling chamber 2, and the water inlet 6 and the water outlet 7 are respectively connected to the two ends of the cooling pipe 5. The cooling pipe 5 is fixed to the outer wall of the reactor 1 in a spiral shape, and the cooling pipe 5 is made of copper alloy. The inner wall of the cooling pipe 5 is evenly distributed with ridges 9, and the cross-section of the ridges 9 is semi-circular.

[0031] The chemical mixture to be treated is fed into the reactor 1 through the feed inlet 10 at the top of the reactor 1. Then, cooling medium, such as cooling water, is introduced into the cooling pipe 5 through the water inlet 6 on one side of the cooling chamber 2 to cool and lower the temperature of the chemical mixture. The cooling pipe 5 is spirally wound around the outer wall of the reactor 1. After the cooling medium absorbs the heat transferred from the reactor 1, it flows out from the water outlet 7 on the other side of the cooling chamber 2, completing the heat exchange cycle. The spiral design increases the contact area between the cooling pipe 5 and the reactor 1 and extends the flow path of the cooling medium. The copper alloy material utilizes its high thermal conductivity to accelerate heat transfer. The semi-circular convex ridges 9 on the inner wall can disturb the flow of the medium to form turbulence, break the boundary layer, and further improve the heat transfer efficiency. The three factors work together to enhance the heat absorption capacity of the cooling pipe 5.

[0032] Please see Figure 1 and Figure 2The reactor 1 is equipped with a stirring mechanism 4, which includes a stirring shaft 402 located at the center of the reactor 1. Stirring blades 403 are evenly distributed on the stirring shaft 402. The stirring mechanism 4 also includes a drive motor 401 located at the top of the reactor 1. The output end of the drive motor 401 is connected to the stirring shaft 402. Spiral blades 404 are evenly distributed at the bottom end of the stirring shaft 402.

[0033] Start the drive motor 401 in the stirring mechanism 4. The output end of the drive motor 401 drives the stirring shaft 402 to rotate. The stirring blades 403 on the stirring shaft 402 also rotate, forcibly stirring the chemical mixture in the reaction vessel 1, breaking the static boundary layer of the mixture, forming turbulence or eddies. The high-temperature liquid is quickly brought to the vicinity of the vessel wall and comes into direct contact with the cooled vessel wall for cooling.

[0034] Please see Figure 1 , Figure 4 and Figure 5 Heat dissipation mechanisms 3 are provided on both sides of the cooling chamber 2 outside the reactor 1. The heat dissipation mechanism 3 includes a heat dissipation fan 301 located at the center of both sides of the cooling chamber 2. A driven gear 302 is provided on the drive shaft of the heat dissipation fan 301, and a driving gear 303 meshes with the driven gear 302. A second synchronous pulley 305 is provided at the top of the driving gear 303 through the transmission shaft 304. The heat dissipation mechanism 3 also includes two sets of first synchronous pulleys 307 located at the top of the stirring shaft 402. The first synchronous pulleys 307 and the second synchronous pulleys 305 are connected by a synchronous belt 306.

[0035] When the stirring shaft 402 rotates, the two sets of first synchronous pulleys 307 at its top rotate with the shaft. Through the synchronous belt 306, the second synchronous pulleys 305 at the top of the transmission shafts 304 on both sides of the cooling chamber 2 rotate synchronously. The transmission shafts 304 drive the drive gear 303 at the bottom to rotate. The drive gear 303 meshes with the driven gear 302 on the drive shaft of the cooling fan 301, thereby driving the two symmetrically distributed cooling fans 301 to rotate. The cooling fans 301 exhaust the heat from the cooling pipes 5 inside the cooling chamber 2. Through forced convection, the heat on the surface of the cooling pipes 5 and inside the cooling chamber 2 is carried away, accelerating the diffusion of heat to the outside environment and preventing the cooling medium from absorbing heat and increasing its temperature, which would reduce the cooling capacity. The cooling fans 301 are symmetrically distributed about the left and right sides of the cooling chamber 2. The cooling chamber 2 is made of aluminum alloy, which has good thermal conductivity and lightweight characteristics. It can quickly conduct heat inside the cooling chamber 2 and work with the cooling fans 301 to accelerate the diffusion of heat to the outside environment, improving the overall heat dissipation efficiency. The top of the cooling chamber 2 has evenly distributed through holes to balance the airflow.

[0036] The first synchronous pulley 307 and the second synchronous pulley 305 have the same diameter, and their central axes are on the same horizontal plane. The synchronous belts 306 are both horizontally tensioned. The outer circumference of the first synchronous pulley 307 and the second synchronous pulley 305 and the inner wall of the synchronous belt 306 are provided with matching toothed structures. The synchronous pulleys with the same diameter ensure that the rotation speed of the stirring shaft 402 and the transmission shaft 304 is consistent. The horizontal collinear design and the tensioned synchronous belt 306 prevent deviation or slippage during transmission. The matching toothed structures realize zero-slip transmission, ensuring the synchronization of the cooling fan 301 and the stirring mechanism 4, and ensuring the synergistic effect of "stirring to enhance heat transfer while the fan simultaneously enhances heat dissipation". Only one drive motor 401 is needed to drive the stirring blades 403 and the cooling fan 301 at the same time, reducing the number of power units, simplifying the equipment structure, and thus reducing energy consumption and maintenance costs. After the chemical mixture is cooled, the drive motor 401 and the supply of cooling medium are stopped, and the discharge port 8 at the bottom of the reaction vessel 1 is opened to discharge the cooled mixture.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
