[0015] Preferably, a sealing gasket is arranged between the rubber clamping block and the tank.

[0016] The effect achieved by the above-mentioned component is that the sealing gasket is arranged between the rubber clamping block and the tank.

[0017] Preferably, the right end of the mounting plate is fixedly connected with an air nozzle, and the air nozzle is fixed with the air bag.

[0018] The effects achieved by the above components are as follows: when the external air pump is fixed to the air nozzle, the air pump is started to inflate the airbag, and when the air pump is switched to suction, the air in the airbag is released, causing it to deflate. Then the rubber clip is completely separated from the inner wall of the box, and the sealing gasket is retracted, which also reduces the wear on the sealing gasket when the mounting plate is dragged.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting up a cleaning component, when it is necessary to clean the sediment at the bottom of the inner wall of the tank, the driving mechanism causes the moving rod to move back and forth in the slide groove, thereby causing the scraper to scrape back and forth at the bottom of the inner wall of the tank, thus scraping off the sediment. Then, the valve is opened to discharge the sediment along with the sewage, thereby achieving the effect of removing the sediment at the bottom of the inner wall of the tank as much as possible. This solves the problem that the waste gas generated by polyethylene glycol production contains dust, which is filtered by water and settles at the bottom of the inner wall of the tank to form sediment, and the drain outlet discharges sewage into the tank, making it difficult to effectively remove the sediment accumulated inside the tank.
