Description

Technical Field

[0001] This utility model relates to the field of medical disinfection facilities technology, and in particular to a pressure steam sterilizer energy storage heating system. Background Technology

[0002] Pressure steam sterilizers are mainly suitable for use in medical operating rooms, dental departments, ophthalmology departments, and biomedical research units. They are used to sterilize pressure-resistant, high-temperature-resistant, and high-humidity-resistant items such as surgical instruments, dental instruments, dressings, glassware, and injection equipment. A vacuum system forcibly extracts the cold air from the sterilization chamber, using saturated hot steam as the sterilizing agent. The items are maintained in a high-temperature, high-pressure, and high-humidity environment for a certain period, causing the proteins of microorganisms in the items to denature and die, thus achieving sterilization. After the sterilization process is complete, the steam in the sterilization chamber is discharged, and the vacuum system is activated to evacuate the chamber, removing the hot steam and thus drying the sterilized items.

[0003] In the prior art, the internal heating mechanism of the pressure steam sterilizer is used to heat water. After the water is heated into steam, it is delivered to the sterilization chamber. The medical instruments inside the sterilization chamber are sterilized by the high-temperature steam. During this process, the lack of pressure detection and control elements inside the evaporator can lead to uncontrolled evaporation rate and steam pressure, which affects the stability of steam delivery to the sterilization chamber. Utility Model Content

[0011] This utility model provides a pressure steam sterilizer energy storage heating system, which has the following beneficial effects:

The evaporator is connected to an evaporator pressure sensor, which can detect the internal steam pressure and monitor the internal pressure in real time. An evaporator safety valve is connected to the evaporator. When the internal pressure of the evaporator exceeds the set pressure of the evaporator safety valve, the evaporator safety valve opens to release pressure and discharge steam to prevent the medium pressure in the pipeline or equipment from being too high and damaging the equipment or pipeline. By controlling the internal pressure of the evaporator to not exceed the specified value, personal safety and equipment operation stability are improved.

[0013] In addition, a sterilization chamber pressure sensor is installed outside the sterilization chamber to detect the internal pressure. When the internal pressure of the sterilization chamber exceeds the set pressure of the sterilization chamber safety valve, the sterilization chamber safety valve opens to release pressure and discharge steam to prevent damage to the internal pipes and chambers of the sterilization chamber. The sterilization chamber is also equipped with an internal temperature sensor to detect and display the internal temperature of the sterilization chamber in real time, which is beneficial for equipment control.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 3 :

[0024] This utility model proposes a pressure steam sterilizer energy storage heating system, comprising: an evaporator 1, with an electric heating tube 101 inside; a water inlet 102 and a drain outlet 105 at the bottom of the evaporator 1; a water inlet check valve 103 installed at the outer end of the water inlet 102; and a water pump 104 connected to the inlet of the water inlet check valve 103 via a pipe; an evaporator pressure sensor 2 connected to the evaporator 1 via a pipe; an evaporator safety valve 3 installed on the evaporator 1 via a pipe; a check valve 4 connected to the evaporator 1; a filter 5 connected to the outer end of the check valve 4; a liquid level probe 6 installed inside the evaporator 1; a steam inlet valve 7 connected to the evaporator 1 via a pipe; and a sterilization chamber 8 connected to the other end of the steam inlet valve 7 via a pipe. An internal temperature sensor 801 is installed on the sterilization chamber 8. Equipped with a test port 802; water is pumped through the inlet pump 104 to pass through the inlet check valve 103 and enter the inlet port 102 to supply water to the evaporator 1, and the liquid water inside the evaporator 1 is heated by the electric heating tube 101 to generate steam. The evaporator 1 stores the steam and hot water. The evaporator 1 is connected to an evaporator pressure sensor 2, which can detect the steam pressure inside the evaporator 1 and monitor the internal pressure of the evaporator 1 in real time. An evaporator safety valve 3 is connected to the evaporator 1. When the internal pressure of the evaporator 1 exceeds the set pressure of the evaporator safety valve 3, the evaporator safety valve 3 opens to release pressure and discharge steam to prevent the medium pressure in the pipeline or equipment from being too high and damaging the equipment or pipeline, thus ensuring the stable operation of the heating system and the steam delivery pipeline.

[0025] In Example 2, based on Example 1, the sterilization chamber 8 is connected to a sterilization chamber pressure sensor 10 via a pipe, a sterilization chamber safety valve 11 via a pipe, a pressure switch 12 via a pipe, and an air input check valve 14 via a pipe. The input of the air input check valve 14 is connected to the output of a return air valve 13, and the input of the return air valve 13 is connected to the output of an air filter 15. The air filter 15 filters and purifies the air entering the sterilization chamber 8, improving the cleanliness of the air entering the sterilization chamber 8. When the internal pressure of the sterilization chamber 8 exceeds the set pressure of the sterilization chamber safety valve 11, the sterilization chamber safety valve 11 opens to release pressure and discharge steam to prevent damage to the internal pipes and chambers of the sterilization chamber 8. The sterilization chamber 8 is also equipped with an internal temperature sensor 801 to detect the internal temperature of the sterilization chamber 8 and display it on an external screen so that the user can understand the internal temperature of the sterilization chamber 8.

[0026] The working principle of this embodiment is as follows: Water is pumped through the inlet pump 104, passing through the inlet check valve 103 and entering the inlet 102 to supply water to the evaporator 1. The liquid water inside the evaporator 1 is heated by the electric heating element 101 to generate steam. The evaporator 1 stores the steam and hot water. An evaporator pressure sensor 2 is connected to the evaporator 1 to detect the internal steam pressure in real time. An evaporator safety valve 3 is connected to the evaporator 1. When the internal pressure of the evaporator 1 exceeds the set pressure of the evaporator safety valve 3, the safety valve 3 opens to release pressure and discharge steam to prevent the medium inside the pipeline or equipment from leaking. If excessive pressure damages equipment or pipelines, when the steam inlet valve 7 is opened, steam from inside the evaporator 1 enters the sterilization chamber 8 through the pipeline. The medical instruments inside the sterilization chamber 8 are sterilized at high temperature using high-temperature steam. At the same time, the pressure inside the sterilization chamber 8 is detected by the sterilization chamber pressure sensor 10. If the pressure inside the sterilization chamber 8 exceeds the set pressure of the sterilization chamber safety valve 11, the sterilization chamber safety valve 11 opens to release pressure, discharging steam to reduce pressure and prevent damage to the pipelines and chambers inside the sterilization chamber 8. The temperature inside the sterilization chamber 8 is detected in real time by the in-boiler temperature sensor 801 and displayed on an external display, facilitating user control of the pressure steam sterilizer.
