Description

Technical Field

[0001] This invention relates to the field of steam sterilization technology, specifically to a steam sterilizer with steam recovery and reuse function. Background Art

[0002] Steam sterilizers are devices that use steam to quickly and reliably disinfect and sterilize items. They can sterilize medical devices, dressings, glassware, and culture media, and are recognized as one of the most reliable sterilization technologies with the best sterilization effect. Related equipment is widely used.

[0003] For example, the utility model patent with announcement number CN213608417U discloses an automatically locking steam sterilizer, which includes a steam sterilizer shell and a cover on its top. The cover is fixedly connected to a locking hook. An interlocking assembly is provided on the steam sterilizer shell. The interlocking assembly includes a fixed seat fixedly connected to the steam sterilizer shell. A stepper motor is fixedly installed on the outer side of one end of the fixed seat. The output end of the stepper motor is connected to a lead screw. A sliding nut is threadedly connected to the outer side of the lead screw. A locking shaft is fixedly connected to the sliding nut. A limit switch is provided in the middle of the fixed seat for triggering after the locking hook descends.

[0004] Taking the aforementioned steam sterilizer as an example, during the application of the steam sterilizer, there are situations where the instrument entry and exit channels are directly connected to the high-temperature steam working chamber. During the sterilization process, the instruments are directly impacted by the high-temperature steam, causing the instrument temperature to change drastically. The temperature change cycle of the instruments is extremely short, which easily leads to metal fatigue. When the lid is opened, some high-temperature steam escapes as the instruments enter and exit. After the steam escapes, under the phenomenon of condensation, it is easy to cause the area around the equipment to become slippery, increasing the probability of accidents. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When this application is used, the steam that has been used to sterilize the instruments in the high-temperature chamber is slowed down and diverted into two medium-temperature chambers. The steam that does not reach the sterilization effect preheats the instruments to be sterilized in the first medium-temperature chamber. After being sterilized by the high-temperature steam in the high-temperature chamber, the instruments will enter the low-temperature chamber after a period of time in the second medium-temperature chamber.

When this application is used, during the process of the material rack opening the partition, a small portion of the steam entering the low-temperature chamber from the medium-temperature chamber is extracted, and the steam temperature inside the medium-temperature chamber is low. In addition, the one-way valve two is connected to the gas supply system.

Therefore, the temperature inside the low-temperature chamber is reduced, avoiding burns to the staff. The humidity of the airflow inside the low-temperature chamber is reduced, which cools and dries the instruments inside the material basket that remain inside the low-temperature chamber, making it convenient to recover the instruments after the material basket has been disinfected and sterilized.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Figures 1-12 As shown, the present invention provides a technical solution for a steam sterilizer with steam recovery and reuse function, including a steam generator 1 and a metal frame 32. A pressurization component is connected to the outlet end of the steam generator 1. A filter screen 33 is fixedly connected to the bottom of the inner cavity of the metal frame 32.

[0022] Specifically, such as Figure 1 As shown, the booster assembly consists of a three-way pipe 3, a dual-inlet dual-outlet booster pump 4, a three-way pipe 5, and a one-way valve 6. One end of the three-way pipe 3 is fixedly connected to the outlet of the steam generator 1, and the other two ends of the three-way pipe 3 are fixedly connected to the two inlets of the dual-inlet dual-outlet booster pump 4, respectively.

The three-way pipe 5 collects the high-pressure steam output by the dual-inlet dual-outlet booster pump 4 and delivers it to the one-way valve 6. The one-way valve 6 delivers the steam to the flow divider 7 in the flow divider assembly, and the one-way valve 6 has a one-way conduction characteristic.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the diversion assembly consists of a sealing frame 18, a sealing frame 22, a gas guide box 10, two sealing frames 35, and two sealing frames 48, all fixedly connected to the outside of the insulation box 9. The sealing frame 18 and the two sealing frames 48 are both fixedly installed on the top of the insulation box 9. An expansion frame 19 is fixedly connected to the top of the low-temperature chamber 54 and to the insulation box 9. The gas guide box 10 is fixedly installed on the top of the expansion frame 19.

Two fixed vertical supports are also fixedly connected to the top of the insulation box 9. A vacuum pump 22 is fixedly connected between plates 23. The air inlet of the vacuum pump 22 is fixedly connected to the second diverter 21. The operation of the vacuum pump 22 is controlled. The vacuum pump 22 draws air from the two sealing frames 18 and the first air guide box 20 through the second diverter 21. The bottom of the first air guide box 20 is fixedly connected to the fourth air guide box 43, which is located inside the low temperature chamber 54. Multiple suction grooves 44 are opened on one side of the fourth air guide box 43. The vacuum pump 22 draws air from multiple positions on the rear side of the low temperature chamber 54 through the first air guide box 20, the fourth air guide box 43 and the multiple suction grooves 44, so that the vapor inside the low temperature chamber 54 is drawn away and the internal temperature of the low temperature chamber 54 is controlled.

[0024] Diverter frame 17 is fixedly installed at the bottom of sealing frame 18. Diverter plate 10 is provided at the bottom of sealing frame 18. Filter screen 2 17 is provided at the bottom of both sealing frames 18. Filter screen 2 17 serves as a filter. Diverter plate 10 and two filter screens 2 17 are fixedly installed through the top of heat insulation box 9. Filter screen 11 is provided at the bottom of diverter plate 10. Diverter plate 2 16 is provided at the bottom of both filter screens 2 17. Filter screen 3 29 is provided at the bottom of low temperature chamber 54. Filter screen 11, two diverter plate 2 16 and filter screen 3 29 are fixedly installed through the bottom of heat insulation box 9. A sealing frame 12 is provided at the bottom of filter screen 11, a sealing frame 35 is provided at the bottom of each of the two diversion plate components 2 16, and a sealing frame 50 is provided at the bottom of filter screen 3 29. The sealing frame 50, the two sealing frames 35, and the sealing frame 22 are all fixedly installed at the bottom of the heat insulation box 9. Both ends of the sealing frame 2 12 are fixedly connected to connecting pipes 13. The inside of each connecting pipe 13 is fixedly connected to a figure-eight pipe 14. When the internal air pressure of the figure-eight pipe 14 is lower than the preset value, one end of the figure-eight pipe 14 automatically closes. When the internal air pressure of the figure-eight pipe 14 exceeds the preset value, the closed ends of the figure-eight pipe 14 are forced open. The connecting pipes 13 are fixedly connected to the two sealing frames 3 15 respectively. The sealing frame 2 12 is connected to the inside of the two sealing frames 3 15 through the two connecting pipes 13.

[0025] Four partitions 2 are fixedly connected inside the heat insulation box 9, dividing the heat insulation box 9 into two medium-temperature chambers and one high-temperature chamber. The two medium-temperature chambers are located on both sides of the low-temperature chamber 54, and the high-temperature chamber is located between the two medium-temperature chambers at the ends away from the low-temperature chamber 54. The first diversion plate 10 and the first filter screen 11 are respectively located at the top and bottom of the high-temperature chamber, the second filter screen 17 are respectively located at the top of the two medium-temperature chambers, and the second diversion plate 16 are respectively located at the bottom of the two medium-temperature chambers. The first diversion plate 10 and the second diversion plate 16 are both porous structures. The first diversion plate 10 and the second diversion plate 16 play a role in steam diversion, and the second filter screen 17 plays a role in water filtration.

[0026] Water inside the high-temperature chamber is discharged through filter screen 11 and then enters the interior of sealing frame 2 12. Water inside the medium-temperature chamber is discharged through diversion plate 2 16 and then enters the interior of sealing frame 3 15. Water inside the low-temperature chamber 54 is discharged through filter screen 3 29 and then enters the interior of sealing frame 5 30.

[0027] Specifically, such as Figure 3 , Figure 5 , Figure 8 , Figure 9 and Figure 10 As shown, the five sealing frame 30, the two three sealing frames 15, and the two sealing frames 12 are all fixedly connected to a pressure relief valve 24. The outlet of the pressure relief valve 24 is fixedly connected to the manifold 25. The bottom of the manifold 25 is fixedly connected to a water storage tank 27. When the water pressure at the inlet of the pressure relief valve 24 exceeds the preset range, the pressure relief valve 24 is opened. After the water stored inside the two sealing frames 12, the two three sealing frames 15, and the five sealing frames 30 reaches a certain amount, the water inside the two sealing frames 12, the two three sealing frames 15, and the five sealing frames 30 automatically enters the water storage tank 27 through the pressure relief valve 24 and the manifold 25. A solenoid valve 28 is fixedly connected to the bottom of one side of the water storage tank 27. By controlling the opening of the solenoid valve 28, the water inside the water storage tank 27 can be drained.

[0028] Both air guide boxes 38 have multiple air outlet grooves 39 on their tops. The air outlet grooves 39 are located inside the low-temperature cavity 54. Both air guide boxes 38 are fixedly connected to air guide box 2 37. A one-way valve 2 40 fixedly connected to one side of air guide box 2 37 is connected to the air supply system. Air is supplied to various positions at the bottom of the low-temperature cavity 54 through air guide box 2 37, two air guide boxes 38 and multiple air outlet grooves 39 to control the internal temperature of the low-temperature cavity 54.

[0029] A guide pipe 41 is fixedly connected to the bottom of the second air guide box 37. A solenoid valve 42 is fixedly connected between one end of the guide pipe 41 and the manifold 25. Water generated by condensation inside the third air guide box 38 is stored at the bottom of the inner cavity of the second air guide box 37. Since the one-way valve 40 is located in the middle of one side of the second air guide box 37, the water supply to the second air guide box 37 is not affected until the water stored inside the second air guide box 37 reaches a certain amount. The solenoid valve 42 is opened, and the water inside the second air guide box 37 enters the manifold 25 through the guide pipe 41 and the solenoid valve 42. The return assembly, composed of the manifold 25, four pressure relief valves 24, water storage tank 27, second air guide box 37, guide pipe 41, and solenoid valve 42, quickly and efficiently collects the wastewater generated during the instrument disinfection process inside the heat insulation box 9, reducing the possibility of wastewater evaporation affecting the disinfection and sterilization quality.

[0030] A fixed horizontal plate 26 is fixedly connected between the manifold 25 and the steam generator 1, and the manifold 25 serves to support the heat insulation box 9.

[0031] Specifically, such as Figure 2 and Figure 10 As shown, a gear 46 is fixedly connected to the bottom outer side of the rotating frame 45. A drive motor 48 and a brake 50 are fixedly connected to one side of the mounting base 47 fixedly connected to the outer side of the steam generator 1. A transmission shaft 51 is fixedly connected to the output end of the drive motor 48, with one end passing through the brake 50. A gear 49 fixedly connected to the drive motor 48 meshes with the gear 46, controlling the operation of the drive motor 48. The drive motor 48 drives the gear 46 to rotate through the transmission shaft 51 and the gear 49, causing the rotating frame 45 to rotate and multiple support components mounted on the gear 46 to rotate.

[0032] Specifically, such as Figure 3 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, there are two connecting shafts 34 fixedly connected between the material carrier 31 and the rotating frame 45 in the support assembly. The material carrier 31 and the rotating frame 45 rotate synchronously. An electromagnet 36 is fixedly connected to the piston end of the pneumatic cylinder 35 fixedly inserted on one side of the material carrier 31. The electromagnet 36 is set inside the material carrier 31. Furthermore, multiple support frames 52 are fixedly connected to the top of the inner cavity of the heat insulation box 9. The multiple support frames 52 are arranged in a ring. A ball bearing 53 is movably installed inside the support frame 52. The ball bearing 53 supports the bottom of the material rack 31 away from the rotating frame 45. The rolling ball bearing 53 reduces the obstruction of the material rack 31's movement and ensures the working stability of the material rack 31.

[0033] Specifically, such as Figure 4 and Figure 7As shown, the separator 2 includes a U-shaped frame 201 and two elastic sheets 202. The two elastic sheets 202 are fixedly installed at the bottom and top of the inner cavity of the U-shaped frame 201, respectively. The U-shaped frame 201 is fixedly installed inside the heat insulation box 9. The elastic sheets 202 can deform. When the material rack 31 moves through the inside of the U-shaped frame 201, the deformation of the elastic sheet 202 meets the movement requirements of the material rack 31, and the deformation of the elastic sheet 202 fits the material rack 31, reducing the amount of steam flowing out through the separator 2 during the process of the material rack 31 passing through the separator 2.

[0034] The steam sterilizer is composed of a steam generator 1, a rotating frame 45, an insulated box 9, a flow distribution assembly, multiple support assemblies, four partitions 2, a low-temperature chamber 54, two air guide boxes 38, and a reflux assembly. The steam sterilizer is connected to a human-machine interface device to control its operation, which is an application of existing technology.

[0035] The working principle of a steam sterilizer is as follows: After the steam generator 1 generates and outputs steam, the instruments to be sterilized are placed into the material basket composed of filter screen 4 33 and metal frame 32. The material basket is then placed into the material rack 31, which moves into the low-temperature chamber 54. Subsequently, the drive motor 48 is controlled to operate, and under the action of brake 50, gear 2 49, and gear 1 46, the rotating frame 45 rotates. The rotating frame 45 drives the material rack 31 to rotate, and the material rack 31 drives the material basket to rotate. Taking the counterclockwise rotation of gear 1 46 as an example, after the material rack 31 and the material basket quickly pass through the separator 2 and enter the first medium-temperature chamber, the drive motor 48 pauses for a period of time and then resumes operation, placing the second material rack inside the low-temperature chamber 54. After the material basket supported by the material rack 31 is transported into the first intermediate temperature chamber, the drive motor 48 pauses for a period of time and then resumes operation to transport the third material rack 31 and the material basket into the first intermediate temperature chamber. The drive motor 48 operates in the above manner. After passing through the first intermediate temperature chamber, the material basket enters the high temperature chamber. After passing through the high temperature chamber, the material basket enters the second intermediate temperature chamber. Finally, the material basket returns to the low temperature chamber 54 and stays there for a period of time. Then, the staff removes it and replaces it with a new material basket. This ensures that the sterilization equipment inside the material basket stays in the two intermediate temperature chambers, the high temperature chamber, and the low temperature chamber 54 for a period of time, thus ensuring the efficiency of sterilization.

[0036] The pressurization component pressurizes the steam and delivers it to the inside of the diverter frame 7. The bottom of the sealing frame 8, connected to the diverter frame 7, is equipped with a diverter plate 10. Under the diversion effect of the diverter frame 7 and the diverter plate 10, the high-temperature, high-pressure steam is diverted and enters various parts of the high-temperature chamber, and the steam rushes towards the filter screen 11. The high-temperature chamber and the two intermediate-temperature chambers are equipped with a separator 2. When the separator 2 is not opened, it has a good sealing effect. The steam inside the high-temperature chamber enters the two intermediate-temperature chambers through the filter screen 11, the sealing frame 2 12, the two connecting pipes 13, the two sealing frames 3 15, and the two diverter plates 2 16. After being diverted and depressurized, the steam inside the high-temperature chamber is dispersed into the two intermediate-temperature chambers. The pump 22 is controlled to operate. The pump 22, through the diverter frame 2 21, the air guide box 1 20, the air guide box 4 43, and the two filter screens 2 17, etc., draws steam from the two intermediate-temperature chambers. Air is evacuated from the intermediate-temperature chamber and the low-temperature chamber 54 to control the steam flow rate and complete the steam utilization process. After the high-temperature chamber sterilizes the instruments, the steam is slowed down and diverted to the two intermediate-temperature chambers. The steam that does not reach the sterilization level preheats the instruments to be sterilized in the first intermediate-temperature chamber. After being sterilized by the high-temperature steam in the high-temperature chamber, the instruments will enter the low-temperature chamber 54 after a period of time in the second intermediate-temperature chamber. This process recovers and utilizes the steam after heat exchange, extends the heating and cooling cycle of the instruments, and reduces the fatigue and aging of the instrument materials caused by high-temperature sterilization. Furthermore, due to the synchronous movement of multiple support components and the structural design of two intermediate-temperature chambers and a relatively long high-temperature chamber, multiple batches of instruments can undergo different sterilization steps simultaneously, ensuring the efficiency of instrument sterilization and the effectiveness of steam sterilization.

[0037] Simultaneously, the vacuum pump 22 draws air from the two sealing frames 18 and the air guide box 20 through the diversion frame 21. The top of the two intermediate temperature chambers is a negative pressure area. The vacuum pump 22 extracts the steam entering the intermediate temperature chamber. The vacuum pump 22 draws air from multiple locations on the rear side of the inner cavity of the low temperature chamber 54 through the air guide box 20, the air guide box 43, and multiple vacuum grooves 44. Moreover, the material carrier 31 passes through the partition 2 in a short time. During the process of the material carrier 31 opening the partition 2, a small portion of the steam enters the low temperature chamber 54 from the intermediate temperature chamber. Steam is drawn away, and the steam temperature inside the medium-temperature chamber is low. In addition, one-way valve 2 40 is connected to the gas supply system. One-way valve 2 40 supplies gas to various positions inside the low-temperature chamber 54 through gas guide box 2 37, two gas guide boxes 38 and multiple gas outlet grooves 39. Therefore, the temperature inside the low-temperature chamber 54 is reduced, avoiding burns to the staff. The humidity of the airflow inside the low-temperature chamber 54 is reduced, which cools and dries the instruments inside the material basket that are inside the low-temperature chamber 54, making it easier to recover the instruments after the material basket has been disinfected and sterilized.

[0038] Under the action of the vacuum pump 22 and the steam supply method inside the high-temperature chamber, most of the steam inside the two medium-temperature chambers and the high-temperature chamber flows vertically. During the movement of the material rack 31, the pneumatic cylinder 35 drives the electromagnet 36. After the working electromagnet 36 comes into contact with the metal frame 32, the electromagnet 36 fixes the iron metal frame 32 by magnetic attraction, so that the metal frame 32 and the electromagnet 36 move synchronously. During the rapid alternating contraction and extension of the pneumatic cylinder 35, the electromagnet 36, the metal frame 32, and the filter screen 33 move rapidly, creating a shaking effect on the top of the filter screen 33. The high-temperature steam moving from top to bottom inside the high-temperature chamber comes into full contact with the instruments carried by the material rack, ensuring the disinfection and sterilization effect. Moreover, the shaking of the instruments helps to shake off the moisture on the outside of the instruments, further increasing the speed at which the instruments dry and cool down inside the low-temperature chamber 54 after disinfection and sterilization, and increasing the speed at which the instruments entering the low-temperature chamber 54 are recovered.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
