A stainless steel pipe pickling tank

Abstract

The invention provides a stainless steel pipe pickling tank which comprises a tank body and a tank cover. An opening is formed in the upper portion of the tank body. A water storage tank surrounding the opening is arranged on the opening. The tank cover is buckled in the water storage tank. The tank cover can be opened along one side of the tank body in a sliding mode. The pickling tank further comprises a tank cover lateral sliding mechanism. The tank cover lateral sliding mechanism comprises a lifting guide rail, rollers arranged on the two sides of the tank cover and matched with the guide rail, an acid fluid circulating device and a spraying system, wherein the acid fluid circulating device comprises a suction pump, a fluid pumping pipe and a fluid discharge pipe, and the fluid pumping pipe and the fluid discharge pipe are arranged on the suction pump; the spraying system is arranged in the tank body. A gas pumping cavity is formed in one end of the tank body, and a gas inlet channel is formed in the other end of the tank body. The tank cover and the water storage tank are sealed in a water injection mode. The lateral sliding type tank cover is compact in equipment structure. The acid fluid circulating device can improve the pickling effect and shorten pickling time. The spraying system can wash acid fluid on the inner cavity of the tank body and on steel pipes. Acid mist in the tank body is pumped away through a gas pumping box, and zero leakage of the acid mist is achieved.

Description

technical field [0001] The invention relates to a pickling tank, in particular to a stainless steel pipe pickling tank. Background technique [0002] For workpieces such as stainless steel pipes, the surface is oxidized to black after annealing, and needs to be pickled to remove the oxide layer and oil stains on the surface. The existing pickling tanks for stainless steel pipes are generally made of plastic plates. Due to the poor rigidity of plastic plates, It is easy to deform after injecting acid solution into the workpiece. Therefore, many pickling tanks made of plastic plates are buried underground to ensure that they do not deform. During the pickling operation of stainless steel pipes, stainless steel pipes will inevitably collide with the pickling tank. The tank wall is easy to cause the tank wall of the pickling tank to be damaged by collision and cause acid leakage. At the same time, because the pickling tank is buried underground, it is difficult to intuitively fi...

Problems solved by technology

[0008] The opening of this patent has no cover, and only relies on the negative pressure generated by the suction of several suction ports arranged at the opening to prevent the acid mist from escaping, but this is only applicable to occasions where the air is relatively static. The negative pressure at the suction port is easily affected by the flow of outside air. At the same time, under the premise of completely sucking the escaping acid mist, the suction volume will be very large, which will greatly increase the burden on the acid mist treatment equipment, increase energy consumption and Equipment input cost
