Abstract
Description
Technical Field
[0001] The invention discloses a splash-proof pressure-free low-temperature drainage box, belonging to the technical field of medical equipment. Background Art
[0002] Steam sterilizer is a common decontamination equipment in the medical industry. According to the maintenance method, it can be divided into steam sterilizers with front and rear maintenance methods and steam sterilizers with side maintenance methods (hereinafter referred to as front and rear sterilizers and side sterilizers, respectively). Side sterilizers are more traditional steam sterilizers. Compared with side sterilizers, front and rear sterilizers have smaller equipment size because the equipment pipes and other accessories are installed at the bottom of the equipment. Therefore, places with limited installation space and harsh drainage conditions are more suitable for the use of front and rear sterilizers.
[0003] According to relevant requirements, after the steam sterilizer completes the disinfection work, due to the high requirements of hospitals for drainage facilities, non-pressure and low-temperature drainage is the current main trend. Therefore, a drainage box is generally installed in the steam sterilizer to discharge the high-temperature and high-pressure water generated during the disinfection process after decompression and cooling. For the front-to-back sterilizer, due to its small size, in addition to the necessary space for equipment pipelines and other accessories, there is insufficient design space for the drainage box, and only a small-sized drainage box can be used. Therefore, when facing the large-flow, high-temperature, and pressurized water source discharged by the equipment, it is easy to cause droplets to splash and the water tank to overflow.
[0004] In the side-type sterilizer, due to its large internal space, the pipes and valves are installed on the side of the sterilizer body, there is sufficient space, and the design of pressure-free low-temperature drainage is adopted. In order to relieve pressure, the drainage box is basically a semi-closed or open structure to overcome the problem of splashing droplets. In the front-to-back sterilizer, due to the limited layout space of the drainage box, the water tank is installed under the equipment, and the height of the installation space is limited. The use of a closed drainage box is prone to high temperature and high pressure in the box, which poses a great safety hazard. If a conventional open box is used, if the drainage box cannot timely decompress and cool the water discharged from the sterilizer before discharging it, it will not only easily generate a large working noise, but also splashing droplets will bring certain safety hazards.

DETAILED DESCRIPTION
[0024] Figures 1 to 6 It is the best embodiment of the utility model, and the following Figures 1 to 6 The utility model is further described.
[0025] like Figures 1 to 4 As shown, a splash-proof pressure-free low-temperature drainage box (hereinafter referred to as the drainage box) includes a box body, which includes a bottom plate 5 and a baffle 3 and a cover plate 12 fixed on the surface of the bottom plate 5. The cover plate 12 is a three-sided surrounding structure, and its bottom circumference is sealed and fixed to the surface of the bottom plate 5. The baffle 3 is arranged at the side opening of the cover plate 12, and the two side edges of the baffle 3 are sealed and fixed to the edges of the corresponding sides of the cover plate 12 respectively.
[0026] Combination Figure 5 The top of the baffle 3 is horizontally bent to the inner side of the box body to form a horizontal part, and the two sides of the horizontal part are respectively sealed and fixed to the two sides of the upper port of the cover plate 12. The inner side of the horizontal part of the baffle 3 is bent downward again to form a first partition 14 in the box body. A partition plate 1 is also fixed to the inner side of the first partition plate 14. The upper part of the partition plate 1 is fitted with the first partition plate 14 and is fixed to the upper part of the first partition plate 14 by bolts. The middle part of the partition plate 1 is horizontally bent to form a horizontal part, and the inner side of the horizontal part of the partition plate 1 is bent downward again to form a second partition plate 17 in the box body. The second partition plate 17 is spaced apart from the inner wall of the cover plate 12, so that the drainage box adopts an open design to quickly complete the pressure relief of the water source discharged from the sterilizer.
[0027] The lower edge of the first partition 14 is higher than the lower edge of the second partition 17, and the first partition 14 and the second partition 17 are used to form divided areas in the body of the drainage box: a high temperature zone 13 between the first partition 14 and the baffle 3, a buffer zone 15 between the first partition 14 and the second partition 17, and a pressure-free zone 16 between the second partition 17 and the cover plate 12, wherein the upper port of the pressure-free zone 16 is the open end of the drainage box.
[0028] A hot water inlet 2 is provided on the side of the cover plate 12, and the hot water inlet 2 is connected to the sterilization chamber of the sterilizer through a pipeline, and the inner port of the hot water inlet 2 in the box is located in the high temperature zone 13. A temperature probe 7 is also provided at the bottom of the cover plate 12, and the temperature probe 7 is also located in the area of the high temperature zone 13, and the temperature probe 7 is located on the other side of the cover plate 12 relative to the hot water inlet 2. A cold water inlet 4 is provided in the middle of the horizontal part of the top of the baffle 3, and the cold water inlet 4 is connected to an external cold water source through a pipeline, and a solenoid valve is provided on the pipeline. The port of the cold water inlet 4 in the box is located in the high temperature zone 13.
[0029] A drain pipe 9 is provided on one side of the temperature probe 7. The outer end of the drain pipe 9 is the main drain port of the drain box. The drain pipe 9 opens at the inner end of the box body and is located in the buffer zone 15. Two openings are provided at the bottom of the bottom plate 5 corresponding to the high temperature zone 13 and the pressure-free zone 16. A drain pipe 6 is installed at the opening of the bottom plate 5 corresponding to the high temperature zone 13. A siphon pipe 11 is installed at the opening of the bottom plate 5 corresponding to the pressure-free zone 16. The drain pipe 6 and the siphon pipe 11 meet at the bottom of the bottom plate 5 and share an outlet: the drain port 10. A drain valve 8 is also installed in the drain pipe 6.
[0030] like Figure 6 As shown, the siphon tube 11 passes through the bottom plate 5 from the bottom and enters the pressure-free zone 16 of the box body. When extending to the upper part of the second partition plate 17 in the pressure-free zone 16, the side is bent. The lower end of the siphon tube 11 opens downward and is spaced apart from the bottom plate 5.
[0031] The specific working process and working principle are as follows:
[0032] The high-temperature and high-pressure water source generated during the sterilizer disinfection process is connected to the hot water inlet 2 through a pipeline, and is discharged into the body of the drainage box through the hot water inlet 2. The water source discharged from the sterilizer first enters the high-temperature zone 13 after entering the box. The water source is in the highest temperature and pressure state when entering the high-temperature zone 13, so the splashing of droplets in the high-temperature zone 13 is the most serious. Since the high-temperature zone 13, the buffer zone 15 and the pressure-free zone 16 are connected to each other, after the water source enters the high-temperature zone 13, it will immediately release pressure through the upper port of the pressure-free zone 16. At the same time, the double spacing of the first partition 14 and the second partition 17 is used to eliminate the splashing of droplets generated by the water source after entering the drainage box.
[0033] After the water source at the inner end of the sterilizer is discharged, a temperature probe 7 detects the temperature of the water source. If it exceeds the preset temperature, the controller of the sterilizer opens the solenoid valve in the external cooling water source pipeline to neutralize and cool the water source discharged from the sterilizer. The water source is first discharged through the drain pipe 9. Since the water source entering from the hot water inlet 2 is in a high-pressure state and the drain pipe 9 is connected to the atmosphere, the water intake of the hot water inlet 2 is greater than the water discharge of the drain pipe 9.
[0034] When the drainage volume of the drain pipe 9 is sufficient to drain the water source, the water is only drained through the drain pipe 9. If the drainage volume of the drain pipe 9 is less than the water inlet volume of the hot water inlet 2, the water level in the drainage box will gradually rise. When the water level in the drainage box rises to the entrance of the siphon pipe 11, the water level in the siphon pipe 11 will rise synchronously with the water level in the drainage box. After the water level at the inner end of the siphon pipe 11 rises to the highest point, the water source will be drained through the highest position of the siphon pipe 11. At this time, a siphon effect is formed in the siphon pipe 11. At this time, the siphon pipe 11 and the drain pipe 9 drain together, thereby increasing the drainage volume to ensure that the water source at the inner end of the drainage box is discharged as soon as possible.
[0035] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
