Description
Technical field
The invention belongs to acid dip pickle technical field, more particularly to a kind of closed acid cleaning device.
Background technology
Forging is that one kind applies pressure to metal stock using metal forming machinery so as to produce plastic deformation to obtain with one
The processing method for determining mechanical performance, definite shape and size forging.Can eliminate what metal was produced in smelting process by forging
The defect such as cast condition is loose, optimizes heterogeneous microstructure, simultaneously because complete metal streamline is saved, the mechanical performance one of forging
As better than same material foundry goods.The technological process of forging processing is typically：1. gropping of forging billet, 2. forging stock heating, 3. roll forging is standby
Base, 4. die-forging forming, 5. trimming, 6. intermediate survey, 7. forging heat treatment, 8. clears up, and 9. corrects, and 10. checks.Cleaning is mainly
The residues such as oxide skin, the greasy dirt of surface of workpiece are removed, and surface of the work is polished the fineness for improving workpiece, work can be made
Part exposes the metal true qualities of uniformity, makes workpiece appearance more attractive, good-looking.Cleaning most common method is exactly pickling.
The place of pickling or device are exactly descaling bath, and the pickled material for often using is hydrochloric acid, is concretely comprised the following steps：Pickling,
Metalwork is placed in into the oxide skin that skim-coat is removed in immersion in pickling tube；Neutralization, using in the alkaline solutions such as alkali hydroxide and removing
The acid solution of metal surface residual；Rinsing, workpiece is taken out, and removes the surface acid solution of metalwork with clear water.General metal works
Pickling is carried out using such step all, but aluminium gold metal work-pieces are amphoteric oxide, can be occurred with alkali with acid reaction again
Reaction, thus be not suitable for being neutralized using alkali liquor after pickling.And carry out pickling using above-mentioned steps and also there is following asking
Topic：（1）A large amount of acid mists are produced in acid cleaning process, it is difficult to collect and recycle, acid mist can to Factory Building and equipment cause corrosion and
Damage, to environment, while being detrimental to health；（2）Water resources consumption amount is big, needs using big after pickling, neutralization
The washings of amount, cause a large amount of wastes of water resource；（3）The cost for wastewater treatment produced after rinsing metal is high, and waste water is straight
Run in put and severe contamination can be caused to environment.
The content of the invention
The purpose of the present invention is providing a kind of closed acid cleaning device, can effectively collect acid mist, ensures operating personnel's body
Safety, it is to avoid equipment is corroded, but also the problem that can not be neutralized using alkali liquor after can solve the problem that aluminium gold metal work-pieces pickling.
In order to achieve the above object, base case of the invention is：Closed acid cleaning device, including the pickling of upper end open
Groove, also including acid mist treatment device and noble gases charging device；The opening of descaling bath is provided with lid；On the descaling bath
Inlet is provided with, a upper lateral part of descaling bath is provided with the breather connected with descaling bath, and another upper lateral part is provided with and is connected with descaling bath
Logical exhaustor, the bottom of descaling bath are connected with drain pipe；The air inlet pipe is provided with the first valve, air inlet pipe and noble gases
Charging device connects；The exhaustor is provided with the second valve, and exhaustor is connected with acid mist treatment device；The drain pipe is provided with
3rd valve, is connected with heating tube on drain pipe, the heating tube is arranged in the bottom of descaling bath and side wall, heating tube built with
Sodium hydroxide solution.
The operation principle of this base case is：When needing the oxide skin to surface of workpiece to process, open
Second valve and lid, pending metal works are put in descaling bath, are closed the lid, then by inlet toward descaling bath
In be passed through hydrochloric acid solution, the acid mist produced in acid cleaning process enters acid mist treatment device by exhaustor.Open after the completion of pickling
First valve and the 3rd valve, close the second valve, operate noble gases charging device, are filled with noble gases toward descaling bath,
Pressure increase in descaling bath, the waste liquid in descaling bath is pressed into heating tube by drain pipe, and metal works also stay in pickling
In groove.When waste liquid is fully transferred in heating tube, the 3rd valve is closed, open the second valve, inertia is introduced toward descaling bath
Gas, enters line replacement to the residual gas in descaling bath, turns off the first valve.Hydrochloride waste is transferred to after heating tube and hydrogen-oxygen
Change sodium solution and neutralization reaction occurs, produce substantial amounts of heat, as the bottom of heating tube and descaling bath, straight wall are contacted, pickling
Temperature in groove is also drastically raised, and the hydrochloric acid of surface of workpiece residual is evaporated from metal works, is entered by exhaustor
Enter acid mist treatment device.After the hydrochloric acid of residual all volatilizees, the first valve is opened, noble gases is passed through again, in descaling bath
Residual gas processed.
The beneficial effect of this base case is：1st, descaling bath acid cleaning process is completely enclosed at one and in less space
Carry out, it is ensured that waste gas can effectively collect acid mist without any leakage, ensure operating personnel's physical safety, it is to avoid equipment is corroded.
2nd, the waste liquid after pickling is using sodium hydroxide neutralization and then discharges again, does not result in environmental pollution.Produce using when acid-base neutralization
The substantial amounts of heat of life, makes the temperature in descaling bath rise sharply, and makes the acid solution of surface of workpiece residual constantly volatilize, surface of workpiece
Acid solution volatilization, disappear after avoid the need for being neutralized which using alkali liquor such as sodium hydroxide, efficiently solve aluminium gold metal work-pieces
A difficult problem for alkali liquor neutralization can not be adopted；And as the waste liquid of surface of workpiece volatilizees, be not required to be rinsed with clear water after pickling again
Metal works, or metal works are cleaned up by only needing a small amount of water, water resource is greatlyd save, water resource is alleviated tight
.3rd, after the waste liquid volatilization of surface of workpiece, noble gases are filled with toward descaling bath, metal surface can be produced by the gas being filled with
Raw impurity blows off, and is not required to additionally clear up the surface of metal works.
Further, the breather is obliquely installed, and side diagonally downward is located in descaling bath.Breather is inclined and is set
Put, during insufflation gas, gas can be directly blown onto the surface of metal works, make the impurity of surface of workpiece be blown off.
Further, the gas in the noble gases charging device is neon.Neon is a kind of colourless, tasteless, non-easy
The gas of combustion, very torpescence, will not be reacted with metal works or acid solution in being filled with descaling bath.
Further, sealing gasket is provided between the lid and descaling bath.The setting of sealing gasket can be prevented effectively from pickling
Acid mist effusion is produced in groove, it is to avoid acid mist is caused to corrode and damaged to Factory Building and equipment, to environment, and harm people
Body health.
Further, pipeline is communicated between the acid mist treatment device and noble gases charging device.Descaling bath works
During, the noble gases being filled with and the acid mist for producing constantly are entered in acid mist treatment device, acid mist Jing acid mists process dress
After putting process absorption, noble gases flow back to noble gases charging device again by pipeline.Noble gases are constantly received again
Collection, utilization, effectively utilize existing resource.
