As shown in Figure 1, in a kind of pickling tube and Fig. 1 acid solution storage pool 1 include acid solution storage pool 1, heating mechanism 2, pump 3 with
And vacuum barrel 4.
Wherein, it is contained with pickling solution in acid solution storage pool 1, is used for extracting into pickling tube (not shown), acid solution storage
The structure for depositing pond 1 is not particularly limited.
It is connected between acid solution storage pool 1 in pickling tube (not shown) and Fig. 1 and is connected to two-way pipeline (not shown), for makes acid
Washing lotion is recycling between acid solution storage pool 1 in pickling tube and Fig. 1.
It is provided with circulation liquid outlet 11 and circulation inlet 12 on acid solution storage pool 1, is used for heat cycles.By recycling
Liquid mouth 11, the pickling solution in acid solution storage pool 1 can flow out.By recycling inlet 12, can add into acid solution storage pool 1
Liquid.
Vacuum barrel 4 is sealing structure.A certain amount of circulation fluid 41 is contained in vacuum barrel 4 in advance, circulation fluid 41 is and acid
The identical pickling solution of pickling solution ingredient in liquid storage pool 1.Circulation fluid 41 does not occupy entire space in vacuum barrel 4, in vacuum barrel 4
Also there are certain spaces for the top of content space, are low-voltage space 42.In device operation, negative pressure will form in low-voltage space 42
(as described below).
It is connected between the circulation liquid outlet 11 of acid solution storage pool 1 and low-voltage space 42 by outlet tube 13.
Circulation fluid 41 is connected to pump 3 by setting opening and necessary connecting tube by the bottom of vacuum barrel 4.Pump 3 is electronic
Pump, using resin impeller, resin impeller will not be generated with pickling solution to react.
Heating mechanism 2 is additionally provided between pump 3 and acid solution storage pool 1.Heating mechanism 2 is graphite heat exchanger, is resistant to pickling
Corrosion.Circulation fluid 41 is evacuated to heating mechanism 2 and heats by 3 work of pump, the pickling solution after heating by inlet tube 14 and
Circulation inlet 12 is discharged into acid solution storage pool 1.
When circulation fluid 41 is extracted out from the vacuum barrel 4 of sealing, low pressure or negative pressure are formed in low-voltage space 42, in negative pressure
Under the action of, the pickling solution in acid solution storage pool 1 is inhaled into vacuum barrel 4, to reach pickling solution by hydronic purpose.
In the present embodiment, pump 3 and heating mechanism 2 are successively set between vacuum barrel 4 and acid solution storage pool 1.Other technologies
In scheme, the position of pump 3 and heating mechanism 2 can also be exchanged.
In the present embodiment, heating mechanism 2 uses graphite heat exchanger, is resistant to pickling corrosion.Certainly, heating mechanism 2 may be used also

Such as Fig. 1, it is additionally provided with liquid level detection gauge 5 in vacuum barrel 4, liquid level detection gauge 5 can detecte circulation fluid in vacuum barrel 4
41 liquid level, liquid level detection gauge 5 is connected to controller 6, and can stop pump 3 by controller 6.
If 4 sealing performance of vacuum barrel is bad, easily air is caused to be inhaled into bucket, causes pickling solution liquid in vacuum barrel 4
Potential drop is low, eventually leads in vacuum barrel 4 full of air (daily this set equipment is unattended).Due to being driven for pickling solution circulation
Dynamic pump 3 is using resin impeller, when being full of air in vacuum barrel 4, will cause pump 3 impellers idle running, finally because of impeller sky
The heat that friction generates when turning burns impeller.
Therefore, liquid level detection gauge 5 is set in vacuum barrel 4, when the pickling solution liquid level of vacuum barrel 4 drops to setting position
When, the capable of emitting alarm signal of liquid level detection gauge 5, and by cutting 3 power supplys of pump of controller 6, forbid pump 3 to continue to run, to protect
Shield 3 impellers of pump are not burnt, and improve safety.
Such as Fig. 1, fluid infusion 43 is additionally provided in vacuum barrel 4.The setting of fluid infusion 43 is at 4 top of vacuum barrel.Fluid infusion can be passed through
Mouth 43 is previously added circulation fluid 41 into vacuum barrel 4 and fills into the water or pickling solution of loss after a period of work in device.
The working principle of the present embodiment is:
3 are pumped by circulation fluid 41(pickling solution in vacuum barrel 4) it extracts out, after the heating of heating mechanism 2, it is discharged into acid solution storage
It is to be used in pond 1.Since circulation fluid 41 is extracted, negative pressure is formed in the vacuum barrel 4 of sealing in low-voltage space 42, suction function will
In acid solution storage pool 1 in pickling solution sucking vacuum barrel 4, to reach pickling solution by hydronic purpose.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
