Description

Technical Field

[0001] This utility model relates to the field of high-pressure steam sterilization equipment technology, and in particular to an exhaust device for a high-pressure steam sterilizer. Background Technology

[0002] High-pressure steam sterilizers are key equipment for sterilizing items using the high temperature and high humidity characteristics of saturated high-pressure steam. The performance of its exhaust system directly affects sterilization efficiency, energy consumption, and operational safety. The stability of the mechanical structure of the lid, as the core sealing and pressure-bearing component of the sterilizer, is equally crucial. Currently, most existing high-pressure steam sterilizers use a single valve structure for their exhaust systems. If the valve malfunctions and high-pressure gas cannot escape, there is a risk of explosion. Therefore, this paper proposes an exhaust system for high-pressure steam sterilizers. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an exhaust device for a high-pressure steam sterilizer, which features a self-exhausting component and an electric pressure relief system. Under normal conditions, the high-pressure gas inside the sterilizer can push up the upper baffle and be discharged through the exhaust channel and pressure relief pipe. If the self-exhausting fails, the controller will open the pressure relief solenoid valve to exhaust the gas after the pressure sensor detects high pressure, thus preventing the sterilizer from exploding and significantly improving safety, overcoming the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An exhaust device for a high-pressure steam sterilizer includes a pot body, a pot lid connected to the top of the pot body, an exhaust port provided on the pot lid, a self-exhausting component provided on the exhaust port, an air guide nozzle provided on the side of the pot lid, an air guide pipe connected to the air guide nozzle, a pressure relief solenoid valve connected to one end of the air guide pipe, a pressure sensor installed on the pot lid, and a controller installed on the pot body.

[0005] As a further embodiment of this utility model: the self-venting assembly includes a fixed pipe fixed to the top of the vent, a U-shaped seat fixed to the top of the vent, a through hole of the same size as the vent opening in the middle of the horizontal section of the U-shaped seat, an upper baffle plate provided at the top horizontal section of the U-shaped seat, a connecting rod connected to the lower end of the upper baffle plate, the bottom end of the connecting rod extending from the vent to the bottom of the pot lid and connected to a lower baffle plate, a spring sleeved on the part of the connecting rod located between the pot lid and the lower baffle plate, a pressure relief pipe fixed at the upper end of the horizontal section of the U-shaped seat and outside the upper baffle plate, and two symmetrically opened air outlet slots on the upper baffle plate.

[0006] As a further improvement of this utility model: the two air outlet slots are located outside the through hole, and the upper baffle is slidably engaged with the inner wall of the pressure relief pipe.

[0007] As a further improvement of this invention, both the pressure sensor and the pressure relief solenoid valve are electrically connected to the controller.

[0008] As a further improvement of this utility model: one end of the pressure relief solenoid valve is connected to an exhaust port, and one end of the exhaust port is inclined.

[0009] As a further improvement of this utility model: a connecting pipe is fixed to the top of the pressure relief pipe, and one end of the connecting pipe is connected to the middle of the exhaust nozzle.

[0010] As a further improvement of this utility model, the inclined end of the exhaust nozzle is connected to a dust cover via a hinge.

[0011] As a further improvement of this utility model: the diameter of the connecting rod is smaller than the diameter of the exhaust port and the through hole, and the diameter of the connecting rod is smaller than the inner diameter of the fixed tube.

[0012] The beneficial effects of this utility model are as follows: 1. Equipped with a self-venting component and an electric pressure relief system, under normal conditions, the high-pressure gas inside the pot can push up the upper baffle and be discharged through the venting groove and pressure relief pipe; if the self-venting fails, the controller will open the pressure relief solenoid valve to release the gas after the pressure sensor detects high pressure, thus preventing the pot from exploding and greatly improving the safety of use.

[0013] 2. The exhaust nozzle is angled to facilitate exhaust, and its end is connected to a dust cover via a hinge. This not only prevents dust and impurities from entering the exhaust nozzle, but also allows high-pressure gas to push it open during pressure relief, ensuring the cleanliness and normal operation of the exhaust device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-6 An exhaust device for a high-pressure steam sterilizer includes a pot body 1, a pot cover 2 connected to the top of the pot body 1, an exhaust port 16 provided on the pot cover 2, a self-exhausting component provided on the exhaust port 16, an air guide nozzle 3 provided on the side of the pot cover 2, an air guide pipe 4 connected to the air guide nozzle 3, a pressure relief solenoid valve 5 connected to one end of the air guide pipe 4, a pressure sensor 12 installed on the pot cover 2, and a controller 11 installed on the pot body 1. The pressure sensor 12 and the pressure relief solenoid valve 5 are both electrically connected to the controller 11.

[0023] The self-venting assembly includes a fixed pipe 14 fixed to the top of the exhaust port 16. A U-shaped seat 10 is fixed to the top of the exhaust port 16. A through hole of the same size as the exhaust port 16 is opened in the middle of the horizontal section of the U-shaped seat 10. An upper baffle 17 is provided at the top horizontal section of the U-shaped seat 10. A connecting rod 15 is connected to the lower end of the upper baffle 17. The bottom end of the connecting rod 15 extends from the exhaust port 16 to the bottom of the pot lid 2 and is connected to a lower baffle 19. A spring 13 is sleeved on the part of the connecting rod 15 located between the pot lid 2 and the lower baffle 19. A pressure relief pipe 9 is fixed at the upper end of the horizontal section of the U-shaped seat 10 and outside the upper baffle 17. Two air outlet slots 18 are symmetrically opened on the upper baffle 17.

[0024] Two vent slots 18 are located on the outside of the through hole, and the upper baffle 17 is slidably engaged with the inner wall of the pressure relief pipe 9.

[0025] One end of the pressure relief solenoid valve 5 is connected to an exhaust port 6, one end of which is inclined. The top end of the pressure relief pipe 9 is fixed with a connecting pipe 8, one end of which is connected to the middle of the exhaust port 6.

[0026] The diameter of the connecting rod 15 is smaller than the diameter of the exhaust port 16 and the through hole, and the diameter of the connecting rod 15 is smaller than the inner diameter of the fixed tube 14.

[0027] During normal use, when the gas pressure inside the pot body 1 increases to a certain level, the high-pressure gas will push the upper baffle 17 upward, compress the spring 13, and the upper baffle 17 will leave the U-shaped seat 10. The gas will enter the pressure relief pipe 9 from the gas outlet groove 18 and be discharged along the connecting pipe 8 and the exhaust nozzle 6 to achieve pressure relief. The pressure sensor 12 detects the pressure value inside the pot 1 and transmits the pressure information to the controller 11. When the air pressure inside the pot 1 increases but the upper baffle 17 cannot be moved, and the pressure value detected by the pressure sensor 12 is too high, the controller 11 controls the pressure relief solenoid valve 5 to open, thereby achieving electric pressure relief and effectively preventing the pot 1 from exploding.

[0028] Example 2 is an optimization based on Example 1, specifically: The inclined end of the exhaust nozzle 6 is connected to a dust cover 7 via a hinge, and the hinge can be set at the top of the dust cover 7.

[0029] The dust cover 7 prevents dust and impurities from entering the exhaust port 6. When the pressure is released, the high-pressure gas will push the dust cover 7 open to stop the pressure release, and the dust cover 7 will close under its own gravity.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
