Technical Field

[0001] This invention relates to the field of airtightness testing technology, specifically to an airtightness testing device for chemical reaction vessel tanks. Background Technology

[0002] Chemical reactors are commonly used equipment in chemical production for various chemical reactions, mixing, heating, and cooling operations. They can be designed in various structural forms according to different process requirements, such as vertical or horizontal, with or without agitator. A reactor typically consists of a cylinder, end caps, a stirrer, a transmission device, a shaft sealing device, and a heat exchange device. Referring to Chinese patent publication number "CN119043602A" entitled "A Chemical Reactor Tank Air Tightness Testing Device," this patent points out that the existing testing method requires manual movement of the reactor tank to the testing position and then manual positioning, which is cumbersome, time-consuming, and labor-intensive, and cannot meet the needs of rapid batch testing of reactor tanks. However, this equipment still has problems with poor testing efficiency and convenience. To address these issues, we propose a chemical reactor tank air tightness testing device.

A transmission plate frame is fixedly installed at the end of the transmission rod, and a transmission end head communicating with the transmission rod is fixedly installed in the middle of the top surface of the transmission plate frame. Each of the conveyor tray frames has a fixedly installed air guide pipe, and a connecting pipe is connected between the air guide pipe and the transmission end head. This is used to draw negative pressure into the test tank when the conveyor tray frame can contact the corresponding test tank.

The two drive gears mesh with each other.

[0009] Preferably, a connecting assembly is provided between the inner slide and the transmission plate frame to drive the drive motor to move up and down with the transmission plate frame.

[0033] In this embodiment of the invention, specifically, a transmission plate frame 12 is rotatably installed inside the machine body 1, and a conveyor plate frame 1201 is fixedly installed at both ends of the transmission plate frame 12. A drive cylinder 3 is fixedly installed inside the machine body 1. The drive cylinder 3 is used to drive the transmission plate frame 12 and the conveyor plate frame 1201 to move up and down inside the machine body 1, so that the conveyor plate frame 1201 can contact the corresponding test tank 6.

[0034] In this embodiment of the invention, specifically, when the test tank 6 moves into the machine body 1 along with the conveyor belt 5, the transmission plate frame 12 can be driven down by the drive cylinder 3 until the conveyor plate frames 1201 on both sides contact the ends of the test tank 6 respectively, thereby sealing the ends of the test tank 6.
