Abstract
The utility model discloses a circulation pipeline of a pickling bath. The circulation pipeline comprises a liquor feeding pipe and a drain pipe that are connected with the pickling bath, wherein the liquor feeding pipe and the drain pipe are respectively connected with a pickling liquor recirculation pump via pipelines, a plurality of spray nozzles are arranged on the liquor feeding pipe close to the coboundary of the pickling bath, and the pipe orifice of the drain pipe is positioned at the low end of the bottom of the pickling bath; the number of the liquor feeding pipe is at least one, and at least one spray nozzle is mounted on the pipe orifice of the liquor feeding pipe; the spray nozzles are mounted on the coboundary of the pickling bath via a hinge or mounted on a bracket close to the coboundary of the pickling bath; and the hinge is used for adjusting the liquid spray direction of the spray nozzle. Since the spray nozzles are additionally mounted at the port ends of the drain pipe, the outlet flow rate of the recycle pickling liquor is changed, and the painted spray nozzles have certain spray and wash effects on the surface of pickling materials. Under the condition of the same pickling time, the circulation pipeline can increase the pickling liquor flow on the pickled materials in unit area.
Description
Technical field
The utility model relates to the pickling tank that is used for metal finishing, is specifically related to a kind of circulation line of pickling tank.
Background technology
Pickle solution in the pickling tank generally remains static in the prior art, or is in the state that slowly circulates.Need the material of pickling in this pickling tank, to carry out surface treatment, the phenomenon that the surface owes to wash can occur.For example steel strip surface is being carried out in the process of pickling, because the velocity of flow of circulation acid solution is slow, and steel band just passes through in pickling tank, and both steel band has entered from an end of pickling tank, under the driving of winding apparatus, holds in addition from one of pickling tank to be drawn out again.Because the time that steel band soaks in pickling tank is shorter, if the acid solution speed of circulation certainly will will have influence on the pickling effect of steel strip surface more slowly.Therefore, be necessary to have reached the purpose that improves the material surface pickling effect by improving the speed of circulation of acid solution in pickling tank.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, designs the circulation line of a pickling tank, makes the pickling tank that is provided with this circulation line, and the effect after its pickling can be significantly improved.
For achieving the above object, the technical solution of the utility model provides a kind of circulation line of pickling tank, described circulation line comprises liquid-inlet pipe and the drain pipe that is connected with pickling tank, described liquid-inlet pipe is connected with the recycle pump of acid solution respectively by the road with drain pipe, described liquid-inlet pipe is provided with several nozzles, described nozzle is arranged near the upper limb of described pickling tank, and the mouth of pipe of described drain pipe is positioned at the low side of the bottom of described pickling tank.
Wherein, described liquid-inlet pipe is provided with one at least.
Wherein, a nozzle is housed at least on the mouth of pipe of described liquid-inlet pipe.
Wherein, described nozzle is installed on the upper limb of described pickling tank by hinge, or is installed near the support of described pickling tank upper limb, and described hinge is used to regulate the hydrojet direction of described nozzle.
Wherein, described nozzle only is installed on the upper limb of described pickling tank one side.
Wherein, the hydrojet port of described nozzle is yi word pattern.
Wherein, be provided with regulated valve on described liquid-inlet pipe and pipeline that described recycle pump is connected, described regulated valve is used to regulate the inlet flow rate of recycle acid washing lotion.
Advantage of the present utility model and beneficial effect are: because the utility model has installed nozzle additional in the port end of drain pipe, the interpolation of this nozzle has changed the exit velocity of circulation acid solution, and lacquer covers nozzle the surface of pickling material has been formed certain injection, scouring effect.This circulation line can improve the acid solution flow of flowing through by pickling material unit surface under identical condition of pickling time.This circulation line has simple in structure, and improvement cost is low, and is easy to use, the characteristics of easy handling.
