Cooling unit for pharmaceutical production line

Abstract

This utility model relates to the technical field of cooling units for pharmaceutical production lines, specifically to a cooling unit for pharmaceutical production lines, including a cooling tower and a cooling unit. The cooling unit is connected to a cooling pump via pipes. When the ambient temperature is below 10 degrees Celsius, the cooling water may cool to a temperature below the cooling unit's start-up threshold due to natural cooling or excessive heat dissipation from the cooling tower, triggering a protective shutdown. The cooling pump, the first valve, and the third valve can be closed, while the second valve and the fourth valve can be opened. Cooling water is then drawn by the chilled water pump and supplied to the air conditioning surface cooler. The cooling water is then returned to the cooling tower via the fourth pipe.

[0002] Cooling units used in pharmaceutical production lines are mainly used in various stages of the production process that require temperature control. By precisely adjusting the temperature, they ensure product quality and process stability. However, existing water chiller units are usually designed to operate within the range of 15-35℃ for the cooling water inlet temperature. When the ambient temperature is below 10℃, the cooling water temperature may drop below the unit's start-up threshold due to natural cooling or excessive heat dissipation from the cooling tower, triggering a protective shutdown and potentially affecting the production of the pharmaceutical production line.

[0003] Therefore, a cooling unit for pharmaceutical production lines is proposed to solve the problems mentioned above. Utility Model Content

It can solve the problem that existing chiller units are usually designed to operate within the range of 15-35℃ for cooling water inlet temperature. When the ambient temperature is below 10℃, the cooling water temperature may drop below the unit's start-up threshold due to natural cooling or excessive heat dissipation from the cooling tower, triggering a protective shutdown and easily affecting the production of pharmaceutical production lines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a cooling tower and a cooling unit. The cooling unit is connected to a cooling pump via a pipe. The inlet of the cooling pump is connected to a first pipe. One end of the first pipe is connected to a first valve. One end of the first valve is connected to a second pipe. A second valve is connected to the outside of the second pipe. The end of the second valve is connected to a third pipe. One end of the third pipe is connected to a water purification device. The water purification device is connected to a chilled water pump via a pipe. The outlet of the chilled water pump is connected to the inlet of an air conditioning surface cooler via a pipe. The outlet of the air conditioning surface cooler is connected to a fourth valve.

[0007] Preferably, one end of the fourth pipe is connected to the cooling tower, and a water supply pipe is provided on the outside of the cooling tower.

[0008] Preferably, a support mechanism is provided on the outside of the water inlet pipe connection of the cooling unit. The support mechanism includes a support base, a slide, an inclined surface, a pressure plate, and rollers. The support base is located on the front side of the cooling unit. The slide is slidably connected to the inside of the support base. The inclined surface is located on the outside of the slide. The pressure plate is rotatably connected to the inside of the support base via a shaft. One end of the pressure plate is rotatably connected to a roller. A sliding groove is provided through the outside of the support base.

[0009] Preferably, one end of the pressure plate is curved, and the curved surface is in contact with the inclined surface of the slide.

[0010] Preferably, an end plate is fixedly connected to one side of the slide, a slot is provided on the outer side of the end plate, a buckle is integrally formed on one side of the support base, a pin is inserted through the outer side of the end plate, and an L-shaped plate is integrally formed on the outer side of the pin.

[0012] Compared with the prior art, this utility model provides a cooling unit for pharmaceutical production lines, which has the following beneficial effects: 1. When the ambient temperature is below 10 degrees Celsius, the cooling water may be cooled to a temperature below the start-up threshold of the cooling unit due to natural cooling or excessive heat dissipation from the cooling tower, triggering a protection shutdown. The cooling pump, the first valve, and the third valve can be closed, and the second valve and the fourth valve can be opened. Cooling water is drawn by the chilled water pump and supplied to the air conditioning surface cooler. Then, the cooling water is sent back to the cooling tower through the fourth pipe. In the cold winter, the low-temperature cooling water can be used for circulating cooling, which can save the power of compressor start-up and save water. In addition, the valves are easy to switch and the operation is convenient. 2. To avoid production disruptions, by modifying the butterfly valves and piping, cooling water can be circulated for cooling during cold winters. This saves energy during compressor startup and water usage, and the valves are easy to switch and operate. Installing a filter before the chilled water pump filters out impurities, preventing damage to the chiller and surface cooler from the cooling water.

[0013] 3. During use, weld the support base to the designated position, then push the slide block upwards, thereby driving the two pressure plates to rotate. This causes the rollers at the ends of the pressure plates to press down on the water inlet pipe of the cooling unit. Combined with the lifting of the end of the support base, this clamps and fixes the pipe, preventing the connection between the pipe and the cooling unit from loosening due to pipe vibration caused by water supply. This provides better support. Furthermore, the slide block, in conjunction with the pressure plates, can fix pipes of different diameters depending on the sliding height of the slide block, offering better adaptability. After clamping, one end of the clip engages with the corresponding slot to complete the adjustment and fixation of the slide block. The clip is then limited and fixed by a pin, providing better anti-detachment effect. Attached Figure Description

[0016] 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.

[0017] Example: Please see Figures 1-5 This embodiment of a cooling unit for a pharmaceutical production line includes a cooling tower 1 and a cooling unit 2. The cooling unit 2 is connected to a cooling pump 3 via a pipe. The inlet of the cooling pump 3 is connected to a first pipe 4. One end of the first pipe 4 is connected to a first valve 5. One end of the first valve 5 is connected to a second pipe 6. The outside of the second pipe 6 is connected to a second valve 7. The end of the second valve 7 is connected to a third pipe 8. One end of the third pipe 8 is connected to a water purification device 9. The water purification device 9 is connected to a chilled water pump 10 via a pipe. The outlet of the chilled water pump 10 is connected to the inlet of an air conditioning surface cooler 11 via a pipe. The outlet of the air conditioning surface cooler 11 is connected to a fourth valve 12. The end of the fourth valve 12 is connected to a fourth pipe 13. The fourth pipe 13 is a tee pipe. A third valve 14 is provided on the outside of the fourth pipe 13.

[0018] When the ambient temperature is below 10 degrees Celsius, the cooling water may cool to a temperature below the starting threshold of the cooling unit 2 due to natural cooling or excessive heat dissipation from the cooling tower 1, triggering a protective shutdown. In this case, the cooling pump 3, the first valve 5, and the third valve 14 can be shut down, while the second valve 7 and the fourth valve 12 can be opened. Cooling water is then drawn by the chilled water pump 10 and supplied to the air conditioning surface cooler 11. The cooling water is then returned to the cooling tower 1 through the fourth pipe 13. In cold winters, low-temperature cooling water can be used for circulating cooling, which can save the power energy for compressor startup and save water. It will not affect the normal operation of the pharmaceutical production line. Furthermore, the valves are easy to switch and operate. The water purification device 9 can use a pre-filter for pipelines to filter impurities and prevent the cooling water from damaging the chiller and surface cooler.

[0019] Furthermore, the third valve 14 is connected to the inlet pipe of the cooling unit 2 via a pipeline, and one end of the second pipeline 6 is connected to the cooling tower 1.

[0020] Furthermore, one end of the fourth pipe 13 is connected to the cooling tower 1, and a water supply pipe is installed on the outside of the cooling tower 1.

[0021] To provide better protection, a support mechanism is installed on the outside of the water inlet pipe connection of the cooling unit 2. The support mechanism includes a support base 15, a slide 16, an inclined surface 17, a pressure plate 18, and a roller 19. The support base 15 is located on the front side of the cooling unit 2, the slide 16 is slidably connected to the inside of the support base 15, the inclined surface 17 is located on the outside of the slide 16, and the pressure plate 18 is rotatably connected to the inside of the support base 15 via a shaft. One end of the pressure plate 18 is rotatably connected to the roller 19. A sliding groove 24 is provided through the outer side of the support base 15. One end of the pressure plate 18 is set with an arc surface, which fits against the inclined surface 17 of the slide 16. An end plate 20 is fixedly connected to one side of the slide 16. A slot 21 is provided on the outer side of the end plate 20. A buckle 22 is integrally formed on one side of the support base 15. A pin 23 is inserted through the outer side of the end plate 20. An L-shaped plate is integrally formed on the outer side of the pin 23. The inner wall of the sliding groove 24 fits against the outer wall of the horizontal part of the slide 16.

[0022] In use, the support base 15 is welded to the designated position, and then the end plate 20 is pushed upward to drive the slide 16 to slide, thereby driving the two pressure plates 18 to rotate. This causes the rollers 19 at the ends of the pressure plates 18 to press down on the water inlet pipe of the cooling unit 2. This, together with the lifting of the end of the support base 15, clamps and fixes the pipe, preventing the pipe from becoming loose due to vibration caused by water supply. This provides better support. After clamping, one end of the buckle 22 engages with the corresponding slot 21 to complete the adjustment and fixation of the slide 16. The buckle 22 is then limited and fixed by the pin 23, providing a better anti-detachment effect.

[0023] Furthermore, the end of the buckle 22 is integrally formed with tooth-shaped protrusions, and the slot 21 is set in a tooth-shaped groove.

[0024] The working principle of the above embodiment is as follows: When the ambient temperature is below 10 degrees Celsius, the cooling water may be cooled to a temperature below the starting threshold of the cooling unit 2 due to natural cooling or excessive heat dissipation of the cooling tower 1, triggering a protection shutdown. The cooling pump 3, the first valve 5 and the third valve 14 can be closed, and the second valve 7 and the fourth valve 12 can be opened. The cooling water is drawn by the chilled water pump 10 and supplied to the air conditioning surface cooler 11. Then, the cooling water is sent back to the cooling tower 1 through the fourth pipe 13. In the cold winter, the low temperature cooling water can be used for circulating cooling, which can save the power of compressor startup and save water. The valves are easy to switch and easy to operate. The water purification device 9 can use a pre-filter for the pipeline to filter impurities and avoid damage to the chiller and surface cooler by the cooling water. In use, the support base 15 is welded to the designated position, and then the end plate 20 is pushed upward to drive the slide 16 to slide, thereby driving the two pressure plates 18 to rotate. This causes the rollers 19 at the ends of the pressure plates 18 to press down on the water inlet pipe of the cooling unit 2. This, together with the lifting of the end of the support base 15, clamps and fixes the pipe, preventing the pipe from becoming loose due to vibration caused by water supply. This provides better support. After clamping, one end of the buckle 22 engages with the corresponding slot 21 to complete the adjustment and fixation of the slide 16. The buckle 22 is then limited and fixed by the pin 23, providing a better anti-detachment effect.

[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
