Jacketed directional liquid cooling assembly

Abstract

This application discloses a jacketed directional liquid cooling assembly, relating to the field of jacketed fermenters. It includes a tank body, a stirring device, a discharge port, a feed port, a jacket, a cooling assembly, a gas outlet pipe, and a gas limiting assembly. A diaphragm pump delivers coolant to a spiral flow channel. When the coolant rises to the top of the spiral flow channel, it flows out through an opening at the top and then naturally flows down through the gap between two adjacent spiral flow channels by gravity. This achieves cooling of the tank's outer surface by two coolants flowing in opposite directions, improving heat exchange efficiency. The flowing coolant can return to the bottom of the separating ring for the next cooling cycle. A spring, a conical block, and a sealing disc ensure sealing before the gas pressure reaches the required level. Once the gas pressure reaches the required level (sterilization complete), high-pressure gas is directly delivered to the diaphragm pump through an inclined pipe, eliminating the need for an external gas source.

Description

Technical Field

[0001] This utility model relates to the field of jacketed fermentation tank technology, and in particular to a jacketed directional liquid cooling assembly. Background Technology

[0002] An off-site sterilization tank is a device used to perform sterilization outside the production process. It is commonly used in industries such as medical, pharmaceutical, and food processing to ensure that products or equipment are sterile before entering the production environment. Off-site sterilization tanks are designed to provide an independent sterilization environment to ensure the safety and effectiveness of the sterilization process.

[0003] After fermentation, the product is transported through pipelines to an off-site sterilization tank, where it is then sterilized by heating and pressurizing. After sterilization, the material is transported back to the tank. Because the material is transferred, it is called an off-site sterilization tank, and it is usually used for the sterilization of liquid materials.

[0004] Existing off-site sterilization tanks require cooling via a cooling assembly after sterilization. However, existing cooling assemblies simply fill the spacer on the outer surface of the tank with coolant, which absorbs heat from the tank to achieve cooling. This method is ineffective, the coolant absorbs heat slowly, and it is inconvenient to use. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention provides a jacketed directional liquid cooling assembly. It has the following advantages:

[0018] 1. The coolant is delivered to the spiral flow channel by a diaphragm pump.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a jacketed 3-type directional liquid cooling assembly, including a tank 1, a stirring device 2 is provided inside the tank 1, a discharge port is provided at the bottom of the tank 1, a feed port is provided at the top of the tank 1, a jacket 3 is provided on the outer surface of the tank 1, a cooling assembly 5 is provided inside the jacket 3, an air outlet pipe 4 is provided at the top of the tank 1, and a gas limiting assembly 6 is provided inside the air outlet pipe 4.

[0028] The cooling assembly 5 includes a partition ring 504 fixedly installed inside the jacket 3. Two fixing blocks 505 are fixedly connected to the upper surface of the partition ring 504. A spiral flow channel 507 is fixedly connected to one side of each of the two fixing blocks 505. The spiral flow channel 507 abuts against the inner wall of the jacket 3.

[0029] Specifically, a diaphragm pump 501 is installed at the bottom of the tank 1. The liquid output end of the diaphragm pump 501 is connected to the inner cavity of the jacket 3 located below the partition ring 504. A three-way pipe 502 is fixedly connected to the liquid output end of the diaphragm pump 501. Connecting pipes 503 are fixedly connected to both ends of the three-way pipe 502. An L-shaped connecting block 506 is fixedly connected to the end of the connecting pipe 503 away from the three-way pipe 502. The top of the L-shaped connecting block 506 passes through the partition ring 504 and is fixedly connected to one side of the fixed block 505. The gas input end of the diaphragm pump is fixedly connected to the top of the inclined insertion pipe 601 through a flexible hose.

[0030] Specifically, the side of the spiral flow channel 507 is attached to and sealed with the inner wall of the jacket 3, and the top of the spiral flow channel 507 is provided with an opening. Through the attachment of the spiral flow channel 507 to the inner wall of the jacket 3 and the setting of the opening, the coolant can rise in the spiral flow channel 507 and then flow down from the opening, thereby realizing the coolant flow in two different directions and improving the heat exchange efficiency.

[0031] Specifically, the partition ring 504 has a rectangular groove inside. The rectangular groove facilitates the flow of coolant back to the bottom of the partition ring 504, so that it can enter the next cooling cycle. After absorbing heat, the coolant returns to the bottom of the partition ring 504 and mixes with the coolant that has not yet been cooled, thereby promoting the heat exchange between the hot and cold coolants.

[0032] Furthermore, the partition ring 504 divides the jacket 3 into two chambers. The inner chamber of the jacket 3, located below the partition ring 504, is filled with coolant, and the coolant level does not exceed the height of the partition ring 504. After receiving the air source, the diaphragm pump 501 begins to transport the coolant located below the partition ring 504 inside the jacket 3. The coolant is transported through the three-way pipe 502 to the connecting pipes 503 on both sides, and then through the connecting pipes 503, L-shaped connecting block 506, and fixing block 505 to the interior of the spiral flow channel 507. The sides of the spiral flow channel 507 are connected to the jacket. The inner wall of sleeve 3 abuts against the coolant, causing the coolant to gradually rise inside the spiral flow channel 507. When the coolant rises to the top of the spiral flow channel 507, it flows out through the opening at the top of the spiral flow channel 507 and then flows down naturally by gravity through the gap between two adjacent spiral flow channels 507. This achieves cooling of the outer surface of the tank 1 by two coolants flowing in opposite directions, thereby improving the heat exchange efficiency. The connection relationship, working principle, and operation sequence between the stirring device 2 and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated on here.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The gas limiting component 6 includes a horizontal plate 604 fixedly connected inside the gas outlet pipe 4. A spring 605 is fixedly connected to the upper surface of the horizontal plate 604. A conical block 602 is fixedly connected to the top of the spring 605. A sealing disc 607 is fixedly connected to the top of the conical block 602. An oblique insertion tube 601 is inserted into the inside of the gas outlet pipe 4.

[0035] Specifically, a rod 603 is fixedly connected to the bottom of the conical block 602. The bottom end of the rod 603 passes through the interior of the horizontal plate 604, and the rod 603 is used to limit the position of the conical block 602 and the sealing plate 607.

[0036] Specifically, a limiting ring 606 is fixedly connected to the inner wall of the air outlet pipe 4. The upper surface of the limiting ring 606 abuts against the lower surface of the sealing disc 607. The limiting ring 606 prevents the spring 605 from excessively pressing down on the sealing disc 607, thus restricting the sealing disc 607 above the limiting ring 606. This provides a pre-tightening force for the spring 605 to retract and reset. Only when the internal air pressure is large enough can the sealing disc 607 be lifted up to achieve gas delivery.

[0037] Furthermore, as the internal temperature and pressure of the tank 1 gradually increase during the sterilization process, pressurization continues after sterilization is completed. At this time, the gas inside the tank 1 will rise and exit through the gas outlet pipe 4. The high-pressure gas drives the sealing disc 607 to rise through the conical block 602, thereby entering the upper part of the sealing disc 607, and then entering the interior of the diaphragm pump 501 through the inclined insertion pipe 601 and the hose, thus providing a gas source for the diaphragm pump 501. No external gas source is required. The spring 605 uses a high-temperature resistant spring type 605. The sterilization temperature of existing off-site sterilization tanks is generally between 120 and 140 degrees Celsius, while the temperature tolerance of the diaphragm pump 501 and the temperature tolerance of the existing spring 605 can both reach above 180 degrees Celsius. Therefore, directly using the high-pressure and high-temperature gas inside the tank 1 for gas supply will not affect the normal operation of the diaphragm pump 501 and the spring 605.

[0038] Working Principle: After material sterilization using the off-site sterilization tank, during the initial cooling process, the internal temperature and pressure of tank 1 gradually increase. Therefore, after sterilization, pressurization continues. At this time, the gas inside tank 1 rises through the outlet pipe 4. The high-pressure gas, driven by the conical block 602, lifts the sealing disc 607, allowing it to enter the area above the sealing disc 607. It then enters the diaphragm pump 501 through the inclined insertion pipe 601 and the flexible hose, providing a gas source for the diaphragm pump 501. No external gas source is required. Upon receiving the gas source, the diaphragm pump 501 begins to pump the coolant located below the separating ring 504 inside the jacket 3. The coolant is pumped through the three-way pipe 502 to the connecting pipes 503 on both sides, and then through the connecting pipes... 503, L-shaped connecting block 506, and fixing block 505 are conveyed to the interior of spiral flow channel 507. The side of spiral flow channel 507 abuts against the inner wall of jacket 3, so that the coolant gradually rises inside spiral flow channel 507. When the coolant rises to the top of spiral flow channel 507, it flows out through the opening at the top of spiral flow channel 507, and then flows down naturally by gravity through the gap between two adjacent spiral flow channels 507. This achieves cooling of the outer surface of tank 1 by two coolants flowing in opposite directions, improving heat exchange efficiency. The flowing coolant then flows back into the space below the partition ring 504 through the rectangular channel inside the partition ring 504, and enters the next cooling cycle, ultimately achieving the post-sterilization cooling operation of the off-site sterilization tank.
