Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, specifically a mechanical sealing device for a pressure cooking kettle with a cleaning structure. Background Technology

[0002] A pressure cooker is a device used for chemical reactions or physical treatments under high temperature and pressure conditions. By heating and pressurizing, substances within the cooker undergo reactions or achieve desired physical changes within a specific temperature and pressure environment, thus realizing various technological objectives such as ore leaching, material synthesis, and food processing. Since pressure cookers operate under high temperature and pressure, sealing is crucial. Mechanical seals are one of the most common sealing methods. They form a reliable seal between the rotating shaft and the cooker body through a tight fit between the rotating and stationary rings, preventing material leakage. Other sealing methods include packing seals, but mechanical seals are increasingly widely used in pressure cookers due to their advantages such as good sealing performance, long service life, and low leakage.

[0003] For example, patent application number 202322858730.2 discloses a mechanical seal device for a reactor. This utility model relates to the field of sealing device technology, and in particular to a mechanical seal device for a reactor. Its technical solution includes a body, on which a first flange is fixedly installed. This utility model provides a guide column with a first elastic element between one end of the contact frame and the pressure plate. When the sealing device is installed together, the first elastic element continuously outputs a thrust to the pressure plate, causing the pressure plate to continuously squeeze the second sealing element to fit against the sealing cavity and the sealing ring. This achieves the effect of automatically adjusting the mechanical seal device in real time according to the size of the gap. However, this mechanical seal device for a reactor can only seal the reactor when heating it. If the inside of the reactor needs to be cleaned, the sealing device needs to be removed and sprayed with water for cleaning.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a mechanical seal device for pressure cooking kettle with a cleaning structure. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical sealing device for a pressure cooker with a cleaning structure to solve the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-2 As shown, a mechanical seal device for a pressure cooker with a cleaning structure includes a sealing device body 1. Multiple connecting pipes 2 are installed on the inner surface of the sealing device body 1, and a pressure nozzle 201 is provided on the lower outer surface of the connecting pipe 2. The pressure nozzle 201 penetrates the sealing device body 1 and is installed inside the sealing device body 1. The advantage of this arrangement is that, through the setting of the pressure nozzle 201, the interior of the pressure cooker can be sprayed and cleaned from multiple angles without opening the sealing device body 1, ensuring the cleanliness of the interior of the pressure cooker.

[0022] Furthermore, a connector 202 is provided at the end of the connecting pipe 2 away from the sealing device body 1, and a connecting ring 203 is installed through the outer surface of the connector 202. The advantage of this arrangement is that multiple connecting pipes 2 can be connected by the connecting ring 203.

[0023] Furthermore, the output end of the connector 202 is provided with a one-way valve 204, and the input end of the one-way valve 204 is provided with a water inlet pipe 205. The advantage of this arrangement is that the direction of the water inlet pipe 205 can be restricted by the one-way valve 204, and leakage of the sealing device body 1 can also be avoided.

[0024] Furthermore, a flange 101 is provided on the outer surface of the sealing device body 1, and a pressure sensor 102 is provided on the upper surface of the flange 101. The advantage of this arrangement is that the pressure inside the pressure cooker can be monitored through the setting of the pressure sensor 102.

[0025] like Figures 3-4 As shown, a pressure control device 3 is provided on the left side of the upper surface of the sealing device body 1, and a pressure control device 301 is provided on the right side of the upper surface of the sealing device body 1. A low-pressure tank 302 is provided at the output end of the pressure control device 301, and a pressure relief port 303 is provided on the outer rear surface of the low-pressure tank 302. The advantage of this arrangement is that the high pressure of the pressure cooking kettle can be collected through the low-pressure tank 302.

[0026] Furthermore, the pressure control device 3 includes a pressure pipe 307 disposed on the upper surface of the sealing device body 1, and a solenoid valve 304 is disposed on the outer circular surface of the pressure pipe 307. The solenoid valve 304 can control the closing and opening of the pressure pipe 307.

[0027] Furthermore, a high-pressure tank 305 is provided at the output end of the pressure pipe 307, and a pressurizing pump 306 is provided on the outer circular surface of the high-pressure tank 305. The advantage of this configuration is that, by setting up the high-pressure tank 305, when the pressure sensor 102 detects that the pressure inside the pressure cooker is insufficient, the pressure inside the high-pressure tank 305 can be controlled by the solenoid valve 304 to quickly enter the interior of the pressure cooker through the pressure pipe 307 to pressurize it. At the same time, when the pressure is too high, the high-pressure gas can enter the interior of the low-pressure tank 302 through the pressure control device 301 for storage, thereby achieving the effect of automatic pressure control of the pressure cooker.

[0028] Working Principle: When using the mechanical seal device for the pressure cooker with a cleaning structure, firstly, the main body 1 of the sealing device is fixed to the upper surface of the pressure cooker via flange 101 to complete the seal. During use, pressure sensor 102 monitors the internal pressure of the pressure cooker. When the pressure is too low, the one-way valve 204 on the outer surface of pressure control device 3 is activated, allowing the pressure from high-pressure tank 305 to enter the interior of the pressure cooker through pressure pipe 307 for constant pressure. If the pressure is too low, the pressure inside the pressure cooker will be collected in low-pressure tank 302 through pressure control device 301 to achieve constant pressure. When cleaning the pressure cooker is required, the water pipe is connected through inlet pipe 205, and the one-way valve 204 is opened, allowing water pressure to enter the interior of connecting pipe 2 through connecting ring 203. Then, pressure nozzle 201 sprays water from multiple angles to clean the interior of the pressure cooker. This is the working principle of the mechanical seal device for the pressure cooker with a cleaning structure.
