The utility model discloses further set up to: the inner wall of the groove body is inclined upwards and outwards.

Through adopting above-mentioned technical scheme, through the inner wall slope setting with the cell body for the cascade forms certain angle with the inner wall of cell body, can wash the impurity on the cell body inner wall better, can slow down the speed that rivers flowed down moreover, can wash the cell body inner wall more fully.

The utility model discloses further set up to: the outer surface of one end of the water curtain pipe, which is positioned outside the tank body, is provided with a plurality of anti-skid bulges.

Through adopting above-mentioned technical scheme, avoid skidding when making to rotate the water curtain pipe through setting up the non-slip raised, it is more convenient to operate.

To sum up, the utility model discloses following beneficial effect has: after the pickling, open external water pipe, rivers flow out from the downthehole formation cascade of water outlet of cascade pipe bottom, open the suction fan simultaneously, through all setting up the air vent in both sides, can absorb acid mist better, make the air vent of both sides be linked together through setting up exhaust passage, acid mist and the impurity granule that the suction fan will waft scattered in the air absorb towards the direction of both sides cascade, when impurity granule passes through the cascade, blocked by the cascade, and in acid mist had got into exhaust passage through the air vent, after that, be siphoned away by the suction fan. The impurity particles and the impurities on the inner wall of the tank body are flushed to the bottom of the tank body by the water curtain along with the impurities on the residual materials on the inner wall of the tank body, so that the aim of cleaning the tank body is fulfilled, the pollution to the working environment is avoided, and the operation is convenient and labor-saving.
