Abstract
The utility model relates to a device for a metallic acid washing production line, in particular to a plastic double-layer tank cover used in an acid washing section, a rinsing section, a pre-cleaning section and on the like of a carbon steel and stainless steel plate production line. The plastic double-layer groove cover changes the single form of the prior acid tank cover into the form of an upper layer and a lower layer and is manufactured by adoption of a PPH plate and sleeved with steel plates, thereby the strength and the service life are increased. An upper cover is sealed by water and connected with a lower cover; and when the pressure in an acid tank is increased, an acid liquid reaches a height and then is quickly exhausted through discharge outlets on both ends of the upper cover, thereby complete operation of a steel strip in the acid liquid is guaranteed and the effect of liquid level invariableness is given play. A supporting plate of the lower cover of the plastic double-layer tank cover has the supporting function and gives play to the function of double sealing of acid mist and the acid liquid when sealed with the upper tank cover, and the leakage of the acid mist is controlled; and the upper cover and the lower cover adopt T-shaped socket connection, thereby assembly, disassembly and maintenance are easy.
Description
Technical field:
The utility model relates to the equipment of pickling lines for metal, particularly a kind of plastic double-layer groove lid that is used for carbon steel, stainless steel materials production line pickling section, rinsing section, pre-washing section etc.
Background technology:
Acid tank is a visual plant in carbon steel, the producing stainless steel process.The groove lid is used to cover acid tank, seals, because individual layer groove lid sealing effectiveness is relatively poor, the acid mist easy to leak makes a very bad impression to Working environment, and perishable other mechanical means.The individual layer groove covers another shortcoming: can not control the acid solution height, steel band can not be moved in acid solution fully.
Summary of the invention:
The utility model purpose is to overcome the deficiencies in the prior art, and a kind of good sealing effect is provided, and can control the double-deck groove lid of acid solution height.
This double-deck groove lid changes acid tank groove lid single form in the past, be divided into double-deck up and down, adopt the PPH plate to be made, and lining steel plate, gain in strength and work-ing life, loam cake adopts water-lute, lower cover links to each other with loam cake, increases pressure in acid tank, discharges through loam cake two discharge outlet rapidly after making acid solution reach height, guarantee that steel band moves fully in acid solution, play liquid level constant effect.Its lower cover back up pad have supporting role and last groove lid together sealing more played acid mist, acid solution double seal effect, the leakage of control acid mist, loam cake adopts T type socket joint to be connected with lower cover, loading and unloading and maintenance are conveniently.
The utility model has the advantages that:
It is divided into double-deck up and down, and lower cover and loam cake internal space are wanted to connect, and can guarantee that steel band moves in acid solution fully, play liquid level constant effect.And loam cake adopts T type socket joint to be connected with lower cover, and loading and unloading and maintenance are convenient.
