Description

Technical Field

[0001] This utility model relates to the field of chemical reagent and auxiliary agent production technology, specifically a cooling tower for the production of chemical reagents and auxiliary agents. Background Technology

[0002] Chemical reagent additives are auxiliary chemicals added during the production, processing, storage, or use of chemical reagents to improve their performance, optimize production processes, or ensure stability. Solid catalysts are one type of additive. During their production, additives need to be temporarily stored after production. If stored directly at excessively high temperatures, microorganisms can easily grow. Therefore, a cooling tower is required.

[0003] A Chinese patent with authorization announcement number CN218410378U discloses a cooling tower for the production of chemical reagents and auxiliaries, including an outer shell, an inner tank inside the outer shell, a water channel between the outer shell and the inner tank, a rotating shaft rotatably connected to the inside of the inner tank via bearings, a stirring paddle detachably connected to the outside of the rotating shaft, and a speed reducer installed on the upper end face of the outer shell. By employing both air cooling and water cooling methods to cool the chemical reagents and auxiliaries, the cooling effect is improved. Moreover, when cooling the chemical reagents and auxiliaries, the motor is turned on, causing the stirring paddle to rotate, thereby agitating the chemical reagents and auxiliaries and accelerating the cooling efficiency, thus significantly improving the cooling effect of the cooling tower for the production of chemical reagents and auxiliaries.

[0004] However, the cooling towers mentioned above still have some problems. In practical applications, the cooling water in the cooling chamber is in a static state. The water close to the tower tube heats up first due to absorbing heat from the additives, but it cannot be carried away in time, gradually forming a high-temperature water layer. Meanwhile, the low-temperature water far from the tower tube is difficult to replenish the heat exchange area, resulting in a significant decrease in the overall heat exchange capacity of the cooling water, which in turn reduces the cooling effect on the additives. Therefore, a cooling tower for the production of chemical reagents and additives is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a cooling tower for the production of chemical reagents and auxiliaries.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A cooling tower for the production of chemical reagents and auxiliaries, comprising a tower cylinder, an outer cylinder installed on the outside of the tower cylinder, forming a cooling chamber between the tower cylinder and the outer cylinder, a sliding frame slidably installed inside the outer cylinder, the sliding frame being L-shaped, metal plates being installed at both ends of the bottom side of the sliding frame, the metal plates being annularly arranged inside the cooling chamber, and several through holes being equidistantly opened inside the metal plates, a support base being installed on one side of the outer cylinder, a drive motor being installed inside the support base, a rotating shaft being installed at the output end of the drive motor, a cam being installed on the outside of the rotating shaft, and one end of the cam... An internal rotating shaft is installed, with a connecting rod rotatably mounted at one end. One end of the connecting rod is mounted on the middle of one side of the sliding frame via a pin. A drive motor drives the rotating shaft to rotate, which in turn causes the cam to rotate. The cam, through the rotating shaft and the connecting rod, drives the sliding frame to move up and down, causing the metal plate to move up and down within the cooling chamber. This promotes forced convection of the cooling water within the cooling chamber, breaking the thermal boundary layer of the cooling water in its static state and accelerating the heat transfer rate. The metal plate itself has good thermal conductivity and can fully absorb the heat from the cooling water during its up-and-down movement, further improving the heat exchange efficiency between the cooling water and the additives, thereby significantly improving the cooling effect on the additives.

[0007] Preferably, a water inlet pipe is connected to the top side of the outer cylinder, and a drain pipe is connected to one side of the bottom end of the outer cylinder. A drain valve is installed inside the drain pipe. The water inlet pipe facilitates the introduction of cooling water into the cooling chamber, providing sufficient cooling medium for the cooling process. The drain pipe and drain valve facilitate the discharge of used cooling water from the cooling tower after the cooling operation is completed, so as to replace it with new cooling water. This ensures that each cooling operation can be carried out under the best cooling conditions, improving the stability and reliability of cooling.

[0008] Preferably, a feed pipe is installed at the top edge of the tower, and a discharge pipe is connected to the bottom side of the tower. The design of the feed pipe allows chemical reagents and additives to smoothly enter the tower for cooling, while the discharge pipe provides a discharge channel for the cooled additives, ensuring the continuity of the production process.

[0009] Preferably, a stirring motor is installed on the top side of the tower, and a connecting shaft is installed at the output end of the stirring motor. The bottom end of the connecting shaft penetrates the tower. Five sets of three stirring blades are equidistantly installed on the outer side of the connecting shaft. Two scrapers are symmetrically installed at the top of the connecting shaft. The scrapers are in contact with the inner wall of the tower. During the cooling process, the stirring motor drives the connecting shaft to rotate, which drives the stirring blades to fully stir the additives in the tower. This allows the additives to form a uniform flow in the tower, avoiding local overheating or overcooling, improving the uniformity of heat exchange between the additives and the cooling medium, thereby accelerating the cooling speed and improving the cooling effect. During the rotation, the scrapers can scrape off the additives adhering to the inner wall of the tower, preventing additive residue and agglomeration.

[0010] Preferably, a connecting pipe is rotatably installed on the outer side of the bottom end of the discharge pipe. Two mounting plates are symmetrically installed on the inner wall of the bottom end of the connecting pipe. A support column is installed on one end of each mounting plate. The top of the support column extends through the inner wall of the discharge pipe and is equipped with a spiral blade. A driven gear is installed on the outer side of the connecting pipe. A fixing plate is installed on the outer side of the discharge pipe. A servo motor is installed on the bottom side of the fixing plate. A support shaft is installed on the output end of the servo motor. A drive gear is installed on the bottom end of the support shaft, and the drive gear and the driven gear mesh with each other. When the cooled additive needs to be discharged, the servo motor starts, and the drive gear and the driven gear drive the connecting pipe to rotate, thereby causing the spiral blade to rotate. The rotation of the spiral blade can generate a downward pushing force on the additive in the discharge pipe, preventing the additive from clogging in the discharge pipe, ensuring that the cooled additive can be discharged from the cooling tower smoothly and quickly, and improving the discharge efficiency.

[0011] Preferably, four support legs are equidistantly installed on the bottom side of the tower, and a control panel is installed on one side of the outer cylinder. The control panel is electrically connected to the electrical components inside the device and is used to operate and control the electrical components inside the device. Operators can conveniently control the start and stop and operating parameters of electrical components such as drive motor, stirring motor, and servo motor through the control panel, thereby realizing centralized control of the cooling tower.

[0012] The advantages of this utility model are:

[0013] 1. When the drive motor of this utility model starts, the output end drives the rotating shaft and the outer cam to rotate. The cam drives the connecting rod to move, so that the sliding frame moves up and down in the outer cylinder. The annular metal plate moves synchronously. The movement of the metal plate breaks the static state of the cooling water in the cooling chamber and forms forced convection. Its corrosion-resistant metal material has excellent thermal conductivity and absorbs heat during movement. The internal through holes reduce resistance and promote water mixing, thereby improving heat exchange efficiency.

[0014] 2. The servo motor of this utility model starts the support shaft and the bottom drive gear to rotate. Because the drive gear meshes with the driven gear, it drives the driven gear and the connecting pipe to rotate synchronously, so that the mounting plate, support column and top spiral blade rotate accordingly. The rotation of the spiral blade generates a downward thrust on the additive in the discharge pipe to prevent the viscous additive from clogging. Finally, the additive is discharged through the bottom of the connecting pipe. Attached Figure Description

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a cooling tower for the production of chemical reagents and auxiliaries includes a tower cylinder 1, an outer cylinder 2 installed on the outside of the tower cylinder 1, forming a cooling chamber between the tower cylinder 1 and the outer cylinder 2, a sliding frame 201 slidably installed inside the outer cylinder 2, the sliding frame 201 being L-shaped, a metal plate 202 being installed at both ends of the bottom side of the sliding frame 201, the metal plate 202 being annularly arranged inside the cooling chamber, a plurality of through holes 203 being equidistantly opened inside the metal plate 202, a support base 204 being installed on one side of the outer cylinder 2, a drive motor 205 being installed inside the support base 204, a rotating shaft 206 being installed at the output end of the drive motor 205, a cam 207 being installed on the outside of the rotating shaft 206, a rotating shaft 208 being movably installed inside one end of the cam 207, a connecting rod 209 being rotatably installed at one end of the rotating shaft 208, and one end of the connecting rod 209 being installed at the middle position on one side of the sliding frame 201 through a pin engagement.

[0024] The top side of the outer cylinder 2 is connected to a water inlet pipe 3, and the bottom side of the outer cylinder 2 is connected to a drain pipe 301. A drain valve 302 is installed inside the drain pipe 301.

[0025] Four support legs 7 are equidistantly installed on the bottom side of the tower 1. A control panel 701 is installed on one side of the outer cylinder 2. The control panel 701 is electrically connected to the electrical components inside the device and is used to control the operation of the electrical components inside the device. During operation, in practical applications, the cooling water in the cooling chamber is in a static state. The water close to the tower 1 heats up first due to absorbing heat from the additive, but cannot be carried away in time, gradually forming a high-temperature water layer. Meanwhile, the low-temperature water far from the tower 1 is difficult to replenish the heat exchange area, resulting in a significant decrease in the overall heat exchange capacity of the cooling water, which reduces the cooling effect on the additive. First, cooling water is injected into the cooling chamber between the tower 1 and the outer cylinder 2 through the water inlet pipe 3. Then, the drive motor 205 is started, and its output... The output end drives the rotating shaft 206 to rotate, which in turn drives the cam 207 on the outside of the rotating shaft 206 to rotate synchronously. When the cam 207 rotates, it drives the connecting rod 209 to move, which in turn drives the sliding frame 201 to move up and down in the outer cylinder 2. The annular metal plate 202 moves up and down synchronously with the sliding frame 201. The up and down movement of the metal plate 202 breaks the static state of the cooling water inside the cooling chamber, which promotes the cooling water to form forced convection in the cooling chamber. Moreover, the metal plate 202 is made of corrosion-resistant metal material with excellent thermal conductivity. During the movement, it absorbs the heat in the cooling chamber through surface contact. The through hole 203 inside it can reduce the movement resistance and allow the cooling water to be further mixed through the through hole 203, thereby improving the heat exchange efficiency.

[0026] The cooled water that has absorbed heat can be discharged through the drain pipe 301 by opening the drain valve 302. If continuous cooling is required, new low-temperature cooling water can be added through the inlet pipe 3 to form a cooling medium circulation.

[0027] Please see Figure 1-5 As shown, a feed pipe 4 is installed at the top edge of the tower 1, and a discharge pipe 401 is connected to the bottom side of the tower 1.

[0028] A stirring motor 5 is installed on the top side of the tower 1. A connecting shaft 501 is installed at the output end of the stirring motor 5. The bottom end of the connecting shaft 501 passes through the tower 1. Five sets of stirring blades 502, each consisting of three blades, are installed at equal intervals on the outer side of the connecting shaft 501. Two scrapers 503 are symmetrically installed at the top end of the connecting shaft 501. The scrapers 503 are in contact with the inner wall of the tower 1.

[0029] A connecting pipe 6 is rotatably installed on the outer side of the bottom end of the discharge pipe 401. Two mounting plates 601 are symmetrically installed on the inner wall of the bottom end of the connecting pipe 6. A support column 602 is installed on one end of the mounting plates 601. The top of the support column 602 penetrates to the inner wall of the discharge pipe 401 and is equipped with a spiral blade 603. A driven gear 604 is installed on the outer side of the connecting pipe 6. A fixing plate 605 is installed on the outer side of the discharge pipe 401. A servo motor 606 is installed on the bottom side of the fixing plate 605. A support shaft 607 is installed on the output end of the servo motor 606. A drive gear 608 is installed on the bottom end of the support shaft 607, and the drive gear 608 meshes with the driven gear 604. During operation, the solid catalyst is a type of auxiliary agent. During its production process, the auxiliary agent needs to be temporarily stored after production. If it is stored directly at too high a temperature, it is easy to breed microorganisms. Therefore, a cooling tower is required. The chemical reagent auxiliary agent to be cooled is transported to the inside of the tower 1 through the feed pipe 4.

[0030] While the cooling medium circulates, the stirring motor 5 is started, and its output end drives the connecting shaft 501 to rotate. The five sets of stirring blades 502 rotate synchronously with the connecting shaft 501 to stir the additives in the tower 1 in all directions, promote the flow of the additives in the tower 1, avoid local overheating of the additives due to static placement, and ensure that all additives are evenly in contact with the inner wall of the tower 1. Then, heat exchange is completed between the tower 1 wall and the cooling water in the cooling chamber. At the same time, the two scrapers 503 at the top of the connecting shaft 501 rotate with the connecting shaft 501 to scrape off the additives adhering to the inner wall of the tower 1, prevent the additives from remaining and clumping, and reduce the thermal conductivity of the tower 1. The steam generated during the cooling process is discharged through the exhaust hole on the top side of the tower 1.

[0031] When the additives in tower 1 are cooled to the target temperature and need to be discharged, the servo motor 606 is started. The output end of the servo motor 606 drives the support shaft 607 to rotate, which in turn drives the drive gear 608 at the bottom of the support shaft 607 to rotate. Since the drive gear 608 and the driven gear 604 mesh with each other, the rotation of the drive gear 608 will drive the driven gear 604 and the connecting pipe 6 to rotate synchronously. The mounting plate 601 rotates with the connecting pipe 6, which in turn drives the support column 602 to rotate. The spiral blades 603 at the top of the support column 602 rotate synchronously. When the spiral blades 603 rotate, they exert a downward thrust on the additives in the discharge pipe 401, preventing the viscous additives from clogging in the discharge pipe 401. Finally, the additives are discharged through the bottom of the connecting pipe 6, completing the entire cooling and discharge process.

[0032] Working principle: First, cooling water is injected into the cooling chamber between the tower 1 and the outer cylinder 2 through the water inlet pipe 3. The drive motor 205 is started, and its output end drives the rotating shaft 206 to rotate, which in turn drives the cam 207 on the outside of the rotating shaft 206 to rotate synchronously. When the cam 207 rotates, it drives the connecting rod 209 to move, which in turn drives the sliding frame 201 to move up and down in the outer cylinder 2. The annular metal plate 202 moves up and down synchronously with the sliding frame 201. The up and down movement of the metal plate 202 breaks the static state of the cooling water inside the cooling chamber, which promotes the cooling water to form forced convection in the cooling chamber. Moreover, the corrosion-resistant metal material of the metal plate 202 has excellent thermal conductivity. During the movement, it absorbs the heat in the cooling chamber through surface contact. The through holes 203 inside can reduce the movement resistance and allow the cooling water to be further mixed through the through holes 203, thereby improving the heat exchange efficiency.

[0033] The chemical reagents and auxiliaries to be cooled are conveyed into the tower 1 through the feed pipe 4;

[0034] While the cooling medium circulates, the stirring motor 5 is started, and its output end drives the connecting shaft 501 to rotate. The five sets of stirring blades 502 rotate synchronously with the connecting shaft 501 to stir the additives in the tower 1 in all directions, promote the flow of the additives in the tower 1, avoid local overheating of the additives due to static placement, and ensure that all additives are evenly in contact with the inner wall of the tower 1. Then, heat exchange is completed between the tower 1 wall and the cooling water in the cooling chamber. At the same time, the two scrapers 503 at the top of the connecting shaft 501 rotate with the connecting shaft 501 to scrape off the additives adhering to the inner wall of the tower 1, prevent the additives from remaining and clumping, and reduce the thermal conductivity of the tower 1. The steam generated during the cooling process is discharged through the exhaust hole on the top side of the tower 1.

[0035] When the additives in tower 1 are cooled to the target temperature and need to be discharged, the servo motor 606 is started. The output end of the servo motor 606 drives the support shaft 607 to rotate, which in turn drives the drive gear 608 at the bottom of the support shaft 607 to rotate. Since the drive gear 608 and the driven gear 604 mesh with each other, the rotation of the drive gear 608 will drive the driven gear 604 and the connecting pipe 6 to rotate synchronously. The mounting plate 601 rotates with the connecting pipe 6, which in turn drives the support column 602 to rotate. The spiral blades 603 at the top of the support column 602 rotate synchronously. When the spiral blades 603 rotate, they generate a downward thrust on the additives in the discharge pipe 401, preventing the viscous additives from clogging in the discharge pipe 401. Finally, the additives are discharged through the bottom of the connecting pipe 6, completing the entire cooling and discharge process.

[0036] The cooled water that has absorbed heat can be discharged through the drain pipe 301 by opening the drain valve 302. If continuous cooling is required, new low-temperature cooling water can be added through the inlet pipe 3 to form a cooling medium circulation.
