Description

Technical Field

[0001] This application relates to the field of sterilization equipment cooling technology, and in particular to a sterilization cabinet cooling water tank device. Background Technology

[0002] In the medical industry, sterilization cabinets are commonly used to disinfect and sterilize medical items. The main principle of this process is to use high-temperature steam to kill harmful bacteria, while a vacuum pump creates a negative pressure inside the cabinet, allowing the high-temperature steam to quickly penetrate and sterilize the items. During operation, both the inner chamber and the jacket of the sterilization cabinet need to discharge high-temperature water. Furthermore, the mixture of high-temperature steam and water extracted by the vacuum pump is also very hot, both of which can easily burn personnel. Therefore, both must be first cooled in a cooling water tank until they reach a certain temperature before being discharged.

[0003] The existing sterilizer cooling water tank includes a tank body, which is equipped with a vacuum pump inlet, a vacuum pump heat exchanger outlet, and a vacuum pump outlet. The vacuum pump inlet and outlet are used to connect to the sterilizer equipment used with the cooling water tank. The tank body also has a cooling water tank inlet, a cooling water tank outlet, and a sterilizer drain outlet. During sterilizer operation, a mixture of high-temperature steam and water enters the cooling water tank through the vacuum pump inlet. Water discharged from the sterilizer's inner chamber and jacket enters the cooling water tank through the sterilizer drain outlet, and then coolant is introduced into the tank through the cooling water tank inlet. After a period of time, the water in the tank cools down and is discharged through the cooling water tank outlet.

[0004] In existing sterilizers, the cooling water tank is simultaneously cooled by both the high-temperature steam and water mixture extracted during vacuuming and the water discharged from the sterilizer's inner chamber and jacket. This may increase the consumption of cooling water and lead to water waste. Summary of the Invention

[0005] In order to minimize the consumption of cooling water, this application provides a cooling water tank device for a sterilization cabinet.

[0006] The sterilization cabinet cooling water tank equipment provided in this application adopts the following technical solution:

[0007] A sterilizer cooling water tank device includes a tank body with a partition dividing the tank body into upper and lower layers. The upper layer of the tank body has a vacuum pump inlet, a cooling water tank inlet, a vacuum pump outlet, and a vacuum pump heat exchanger outlet, both of which are used to connect to a sterilizer device used with the sterilizer cooling water tank device. The lower layer of the tank body has an inner chamber drain outlet, a jacket drain outlet, and a cooling water tank outlet, both of which are used to connect to the sterilizer device used with the sterilizer cooling water tank device. A connecting pipe is provided on the partition, connecting the upper and lower layers of the tank body.

[0008] By adopting the above technical solution, when the sterilizer is in use, the mixture of high-temperature steam and water extracted by the vacuum pump enters the upper layer of the tank through the vacuum pump inlet. The location of the vacuum pump heat exchanger outlet facilitates the transfer of some heat to the sterilizer for drying the sterilized items. Subsequently, cooling water is introduced into the tank through the cooling water tank inlet. After the mixture of high-temperature steam and water is neutralized and cooled by the cooling water, and reaches a certain volume, it overflows to the lower layer of the tank through the pipe. At this time, the higher-temperature water inside the sterilizer is introduced into the tank through the inner chamber drain and the jacket drain. The water overflowing from the upper layer undergoes secondary neutralization and cooling with the higher-temperature water inside the sterilizer. When the temperature drops to a certain level, the water is discharged from the tank through the cooling water tank drain. By using the water cooled by the mixture of high-temperature steam and water to perform secondary neutralization and cooling of the higher-temperature water inside the sterilizer, the consumption of cooling water can be minimized, and water resources are not wasted.

[0009] In one specific implementation, the lower layer of the tank is provided with a first temperature probe port.

[0010] By adopting the above technical solution, the setting of the first temperature probe port makes it easy to insert the temperature probe into the lower layer of the tank and monitor the temperature of the water in the tank. When the water temperature drops to the specified temperature, the cooling water tank inlet can be closed in time and the water can be discharged from the tank, thus avoiding excessive consumption of cooling water.

[0011] In one specific implementation, the top of the tank is provided with an observation port, and the bottom of the tank is provided with a maintenance drain port, with the observation port located above the through pipe.

[0012] By adopting the above technical solution, the setting of the observation port and maintenance drain port facilitates the drainage of water in the tank during maintenance. The maintenance drain port at the bottom of the tank can be used to drain the water in the tank, while the observation port above the pipe allows for real-time observation of the tank, thereby improving the convenience of using the cooling water tank.

[0013] In one specific implementation, a sliding tube is slidably connected inside the through pipe, the outer wall of the sliding tube is in contact with the inner wall of the through pipe, and the top of the tank is provided with a driving component for driving the sliding tube to slide in the vertical direction.

[0014] By adopting the above technical solution, the sliding tube can be driven to slide vertically by activating the drive component. The extension of the sliding tube out of the through pipe can indirectly change the height of the through pipe to a certain extent, thereby increasing the cooling time of the water in the upper layer of the tank and thus extending the cooling time of the water in the upper layer of the tank.

[0015] In one specific implementation, the drive assembly includes a dual-axis motor and a rack. The dual-axis motor is disposed on the top surface of the tank, and the rack is vertically arranged. The top end of the rack passes through the top surface of the tank and is slidably connected to the tank. The bottom end of the rack is connected to the slide tube. The output end of the dual-axis motor is connected to a gear, which meshes with the rack.

[0016] By adopting the above technical solution, after the dual-axis motor is started, the output end of the dual-axis motor drives the gear to rotate. Since the gear meshes with the rack, the rack can move the slide tube vertically inside the tank. The gear and rack drive method has high transmission accuracy and is easy to implement.

[0017] In one specific implementation, a retaining ring is provided inside the through pipe, the outer wall of the retaining ring is in contact with the inner wall of the through pipe, and the retaining ring is located below the slide pipe.

[0018] By adopting the above technical solution, the retaining ring can prevent the sliding pipe from falling from the through pipe to the lower layer of the tank due to accidental circumstances.

[0019] In one specific implementation, the upper layer of the tank is provided with a second temperature probe port.

[0020] By adopting the above technical solution, the setting of the second temperature probe port makes it easy to extend the temperature probe into the upper layer of the tank and monitor the temperature of the water in the tank, thereby confirming the specific temperature of the water in the upper layer of the tank to a certain extent.

[0021] In one specific implementation scheme, the through pipe is a square pipe, the through pipe is vertically arranged, the top end of the through pipe is rotatably provided with a rotating shaft, one end of the rotating shaft is connected to a cover plate, the other end of the rotating shaft is connected to a rotating motor, the cover plate is located at the opening at the top end of the through pipe and covers the opening; a temperature sensor is provided on the cover plate.

[0022] By adopting the above technical solution, the rotating motor is started, which drives the rotating shaft and the cover plate to rotate, thereby covering the top opening of the pipe. This prevents the cooling water in the upper layer of the tank from overflowing to the lower layer through the pipe. After the temperature sensor detects a certain temperature, the rotating motor is started to make the cover plate fold up, allowing the water in the upper layer of the tank to overflow to the lower layer, thereby extending the cooling time of the water in the upper layer of the tank.

[0023] In one specific implementation scheme, there are several cover plates, and all of the cover plates together cover the opening at the top of the pipe. Each cover plate is connected to the rotating motor through the rotating shaft.

[0024] By adopting the above technical solution, and by setting several cover plates to cover the opening at the top of the pipe, the pressure on the rotating motor when there is too much water accumulation in the upper layer of the tank can be effectively distributed, thereby extending the service life of the rotating motor.

[0025] In one specific implementation scheme, the inner wall of the bottom end of the conduit is arc-shaped and gradually approaches the axis of the conduit in a downward direction.

[0026] By adopting the above technical solution, the inner wall of the bottom end of the pipe is arc-shaped and gradually approaches the axis of the pipe in the downward direction, so that the outlet of the pipe is smaller than the inlet. When the water in the upper layer of the tank overflows to the lower layer of the tank, the pipe can play a certain buffering and stabilizing role, so that the water in the upper layer of the tank flows into the lower layer of the tank more smoothly.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the sterilizer is in use, the high-temperature steam and water mixture extracted by the vacuum pump enters the upper part of the tank through the vacuum pump inlet. The exhaust port of the vacuum pump heat exchanger facilitates the transfer of some heat to the sterilizer for drying the sterilized items. Cooling water is then introduced into the tank through the cooling water tank inlet. After the high-temperature steam and water mixture is neutralized and cooled to a certain level, it overflows to the lower part of the tank through a pipe. At this point, the higher-temperature water inside the sterilizer is introduced into the tank through the inner chamber drain and jacket drain. The water overflowing from the upper level undergoes secondary neutralization and cooling with the higher-temperature water inside the sterilizer. When the temperature drops to a certain level, the water is discharged from the tank through the cooling water tank drain. By using the water cooled by the mixture of high-temperature steam and water to perform secondary neutralization and cooling of the higher-temperature water inside the sterilizer, the consumption of cooling water can be minimized, preventing water waste.

[0029] 2. The inclusion of an observation port and a maintenance drain port facilitates maintenance of the tank. The maintenance drain port at the bottom of the tank allows for the emptying of water from the tank, while the observation port above the pipe allows for real-time monitoring of the tank, thus improving the convenience of using the cooling water tank.

[0030] 3. Start the rotating motor. The rotating motor can drive the rotating shaft and the cover plate to rotate, thereby covering the top opening of the pipe. This prevents the cooling water in the upper layer of the tank from overflowing to the lower layer through the pipe. After the temperature sensor detects a certain temperature, start the rotating motor to make it fold up the cover plate, allowing the water in the upper layer of the tank to overflow to the lower layer, thereby extending the cooling time of the water in the upper layer of the tank.

[0040] The present application will be further described in detail below with reference to the accompanying drawings.

[0041] This application discloses a sterilization cabinet cooling water tank device.

[0042] Example 1

[0043] Reference Figure 1 The sterilizer cooling water tank equipment includes a vertically arranged tank 1, combined with... Figure 2 The tank body 1 has a horizontally arranged partition 8, which divides the tank body 1 into upper and lower layers. The top of the tank body 1 has a vacuum pump discharge port 13 and a vacuum pump heat exchanger discharge port 14. The upper side wall of the tank body 1 has a vacuum pump inlet 12 and a cooling water tank inlet 15, with the cooling water tank inlet 15 located above the vacuum pump inlet 12. Both the vacuum pump inlet 12 and the vacuum pump heat exchanger discharge port 14 are used to connect to sterilization equipment used with the sterilization cabinet's cooling water tank equipment. The lower side wall of the tank body 1 has an inner chamber drain port 17, a jacket drain port 18, and a cooling water tank drain port 16. Both the inner chamber drain port 17 and the jacket drain port 18 are used to connect to the sterilization cabinet equipment used with the sterilization cabinet's cooling water tank equipment.

[0044] Reference Figure 1 and Figure 2A vertically arranged pipe 2 is installed on the partition 8, connecting the upper and lower layers of the tank 1. A first temperature probe port 3 and a maintenance drain port 19 are also provided on the lower side wall of the tank 1. An observation port 11 is located at the top of the tank 1, directly above the pipe 2. The first temperature probe port 3 facilitates the insertion of a temperature probe into the lower layer of the tank 1 to monitor the water temperature. When the water temperature drops to a specified level, the cooling water tank inlet 15 can be closed promptly, and water can be drained from the tank 1, thus minimizing cooling water consumption. The observation port 11 and maintenance drain port 19 facilitate maintenance of the tank 1. The water in the tank 1 can be drained through the maintenance drain port 19 at the bottom of the tank 1, while the observation port 11 above the pipe 2 allows for real-time observation of the tank 1. When the sterilizer is in use, the mixture of high-temperature steam and water extracted by the vacuum pump enters the upper layer of tank 1 through the vacuum pump inlet 12. The vacuum pump heat exchanger outlet 14 facilitates the transfer of some heat to the sterilizer for drying the sterilized items. Cooling water is then introduced into tank 1 through the cooling water tank inlet 15. After the mixture of high-temperature steam and water is neutralized and cooled to a certain level, it overflows into the lower layer of tank 1 through the pipe 2. At this point, higher-temperature water from inside the sterilizer is introduced into tank 1 through the inner chamber drain 17 and the jacket drain 18. The water overflowing from the upper layer undergoes secondary neutralization and cooling with the higher-temperature water inside the sterilizer. When the temperature drops to a certain level, the water is discharged from tank 1 through the cooling water tank outlet 16. By using the water cooled by the mixture of high-temperature steam and water to perform secondary neutralization and cooling of the higher-temperature water inside the sterilizer, the consumption of cooling water can be minimized, thus preventing water waste.

[0045] The implementation principle of Example 1 is as follows: When the sterilizer is in use, the mixture of high-temperature steam and water extracted by the vacuum pump enters the upper layer of tank 1 through the vacuum pump inlet 12. The setting of the vacuum pump heat exchanger outlet 14 facilitates the transfer of some heat to the sterilizer for drying the sterilized items. Subsequently, cooling water is introduced into tank 1 through the cooling water tank inlet 15. After the mixture of high-temperature steam and water is neutralized and cooled by the cooling water, it overflows to the lower layer of tank 1 through the pipe 2 when it reaches a certain amount. At this time, the higher-temperature water in the sterilizer is introduced into tank 1 through the inner chamber drain outlet 17 and the jacket drain outlet 18. The water overflowing from the upper layer is neutralized and cooled a second time with the higher-temperature water in the sterilizer. When the temperature drops to a certain level, the water is discharged from tank 1 through the cooling water tank outlet 16. By using the water cooled by the mixture of high-temperature steam and water to neutralize and cool the higher-temperature water in the sterilizer a second time, the consumption of cooling water can be minimized, thus preventing water resources from being wasted.

[0046] Example 2

[0047] The difference between this embodiment and Embodiment 1 is that: (Refer to...) Figure 3 and Figure 4 A second temperature probe port 4 is provided on the upper side wall of tank 1. The placement of the second temperature probe port 4 facilitates the insertion of a temperature probe into the upper layer of tank 1 to monitor the temperature of the water inside tank 1. Combined with... Figure 5 A sliding tube 21 is slidably connected inside the through pipe 2. The outer wall of the sliding tube 21 is in contact with the inner wall of the through pipe 2. A retaining ring 22 is fixedly installed inside the through pipe 2. The outer wall of the retaining ring 22 is in contact with the inner wall of the through pipe 2. The retaining ring 22 is located below the sliding tube 21. The retaining ring 22 is designed to prevent the sliding tube 21 from falling from the through pipe 2 to the lower layer of the tank 1 due to accidental circumstances.

[0048] Reference Figure 3 and Figure 4 A drive assembly 5 is provided at the top of the tank body 1. The drive assembly 5 includes a dual-axis motor 51 and two racks 53. The dual-axis motor 51 is fixedly installed on the top surface of the tank body 1. Both racks 53 are vertically arranged, and the top ends of both racks 53 pass through the top surface of the tank body 1 and are slidably connected to the tank body 1. Figure 5 The bottom ends of both racks 53 are fixedly connected to the top end of the slide tube 21. Gears 52 are fixedly connected to both output ends of the dual-axis motor 51. Gears 52 and racks 53 are in one-to-one correspondence, meshing with each other. After starting the dual-axis motor 51, its output ends drive the gears 52 to rotate. Because the gears 52 mesh with the racks 53, the racks 53 can move the slide tube 21 vertically within the tank 1. The slide tube 21 extending out of the through-pipe 2 can indirectly change the height of the through-pipe 2 to a certain extent, thus extending the cooling time of the water in the upper layer of the tank 1.

[0049] The implementation principle of Example 2 is as follows: When the upper layer of the tank 1 is cooled, the dual-axis motor 51 can drive the slide tube 21 to slide in the vertical direction. The slide tube 21 extends out of the through pipe 2, which can indirectly change the height of the through pipe 2 to a certain extent, thereby extending the cooling time of the water in the upper layer of the tank 1.

[0050] Example 3

[0051] The difference between this embodiment and Embodiment 1 is that: (Refer to...) Figure 6 In this embodiment, the through pipe 2 is a square pipe, combined with Figure 7Two rotating shafts 24 are symmetrically arranged at the top of the tube 2. A cover plate 23 is fixedly connected to one end of each shaft 24, and a rotating motor 9 is connected to the other end of each shaft 24. The rotating motor 9 is fixedly installed inside the tube 2. Two cover plates 23 are located at the opening at the top of the tube 2 and together cover the opening. A temperature sensor 7 is installed on the top surface of each cover plate 23. Figure 1 The rotating motor 9 is started, which drives the rotating shaft 24 and the cover plate 23 to rotate, thus covering the top opening of the connecting pipe 2. This prevents the cooling water in the upper layer of tank 1 from overflowing to the lower layer through the connecting pipe 2. After the temperature sensor 7 detects a specified temperature, the rotating motor 9 is started again, causing the cover plate 23 to fold downwards, allowing the water in the upper layer of tank 1 to overflow to the lower layer, thereby extending the cooling time of the water in the upper layer of tank 1. By using two cover plates 23 to cover the top opening of the connecting pipe 2, the pressure on the rotating motor 9 when there is excessive water accumulation in the upper layer of tank 1 can be distributed as much as possible, thus effectively extending the service life of the rotating motor 9. Figure 8 The inner wall of the bottom end of the pipe 2 is arc-shaped and gradually approaches the axis of the pipe 2 in a downward direction. The outlet of the pipe 2 is smaller than the inlet. When the water in the upper layer of the tank 1 overflows to the lower layer of the tank 1, the inner wall of the pipe 2 can play a certain role in buffering and stabilizing the flow, so that the water in the upper layer of the tank 1 flows into the lower layer of the tank 1 more smoothly.

[0052] The implementation principle of Example 3 is as follows: When the upper layer of tank 1 is cooled, the rotating motor 9 is started. The rotating motor 9 can drive the rotating shaft 24 and the cover plate 23 to rotate, thereby covering the top opening of the pipe 2, so that the cooling water in the upper layer of tank 1 cannot overflow to the lower layer through the pipe 2. After the temperature sensor 7 detects a certain temperature, the rotating motor 9 is started again to drive the cover plate 23 to fold down, so that the water in the upper layer of tank 1 can overflow to the lower layer, thereby prolonging the cooling time of the water in the upper layer of tank 1.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
