The telescopic stop driving mechanism can be driven by air pressure or oil pressure. When the telescopic stop driving mechanism drives the first rod 61 to extend out relative to the second rod 62, the first rod 61 pushes the upper part of the scraping plate 421 to swing outwards, and at the moment, the lower part of the scraping plate 421 automatically swings inwards under the action of a lever principle.
In order to clean the scraped dirt to the outside of the tank body 1, the cleaning device further comprises a pump 8 arranged on the upper portion of the frame 2, the vertical rod 3 is a hollow hard pipeline, and the upper portion of the hard pipeline penetrates through the thickness direction of the frame 2. The inlet end of the pump 8 is communicated with the interior of the vertical rod 3, and the outlet end of the pump 8 is arranged on the outer side of the tank body 1. The lower end part of the hard pipeline extends into the tank body 1 and is infinitely close to the bottom surface of the tank body 1, but is not in direct contact with the bottom surface. When the pump 8 is started, dirt in the tank body 1 can be sucked from the hard pipeline, so that manual cleaning is avoided. In order to ensure that the dirt can be sucked by the pump 8, secondary water can be introduced into the tank body 1, and the water also flows to the bottom of the tank along the vertical wall of the tank body 1 or is directly guided to the bottom of the tank through a water pipe. And (4) secondarily using water to sweep dirt on the bottom of the tank, and mixing to form a mixed solution. The pump 8 is preferably a mud pump 8, and can sufficiently pump the mixed solution, pump dirt and secondary water out of the tank body 1 together, and avoid blocking a water outlet of the tank body 1. In order to facilitate the absorption of the mixed solution, a hollow funnel part is arranged at the lower end part of the hard pipeline, one end of a small opening of the funnel part is connected and communicated with the hard pipeline, and one end of a large opening of the funnel part is right opposite to the direction of the bottom of the hard pipeline. In one embodiment, the vertical rod 3 comprises a plurality of hollow hard pipes, and two adjacent hard pipes are detachably connected together from top to bottom. The removable connection is preferably a threaded connection to ensure that the outer surface of the rigid conduit does not protrude any part, hindering the up and down movement of the moveable sleeve 41.
The working principle is as follows: the depth of the scraping and washing mechanism 4 extending into the tank body 1 and the relative height of the movable piece 424 on the movable sleeve 41 are properly adjusted according to the size of the interior of the tank body 1, so that the lower part of the scraping plate 421 is just abutted against the top of the inner surface of the corresponding vertical wall of the tank body 1. Then extend downwards through the telescopic mechanism 5, drive the whole scraping and washing mechanism 4 to move vertically downwards, at this time, each scraper 421 moves towards the bottom of the tank along the inner surface of the corresponding vertical wall of the tank body 1 until all the dirt on the vertical wall is scraped off. At this time, the secondary water may be added to the tank to sufficiently mix the dirt with the secondary water. Then, the pump 8 is started to pump the secondary water and dirt in the tank body 1 out of the tank body 1 from the hollow vertical rod 3, and one-time cleaning operation of the waste acid recycling and regenerating tank is completed.
