In this utility model, described storage acid tank is provided with temperature sensor 4, densitometer 20 and heater 9, respectively
Acid strength, temperature and heating acid solution in detection storage acid tank 5, by detection acid solution acid strength, temperature, electric-controlled
System 2 processed controls heating acid solution and heats acid solution.Heater, according to the temperature arranged in system, can add automatically
Heat), electric-control system can adjust other technological parameter according to the concentration measured.Washings in water tank 10 are by water pump 11 pump
Send, through water pump check-valves 12, arrive entrance reversal valve entrance.Washings commutate through entrance reversal valve, to connecting tube
Tubing 24 in road 14 and descaling bath assembly 1 is discharged by the leakage fluid dram (A1 or A2) of tapping valve 15 after rinsing, due to
First reversal valve 13 commutates action, and rinsing liquid flow direction also can commutate.
(a, b, c, d), wherein a, c mouth is inlet to four connectors that have of descaling bath assembly, and b, d mouth is liquid outlet.
Acid solution is pumped by acid pump 8, through peracid pumping hole check-valves 7, arrives the first reversal valve entrance.First reversal valve commutation is passed through
Electric control system 2 controls, can be to a mouth of descaling bath assembly 1 or the acid of c confession.First reversal valve is to descaling bath assembly
Check valve 16 it is provided with on pipeline between 1.
Under the first reversal valve and the second reversal valve power failure state, acid solution is entered b mouth by the c mouth of descaling bath assembly 1 and flows back to
Process as follows.Such as Fig. 2, when the first reversal valve dead electricity, the c mouth flowing of acid solution right in figure, right one-way valve
16 open under acid action of hydraulic force, and acid solution is entered the left side cavity flowing to descaling bath assembly 1 by c mouth, because of descaling bath assembly
There is another check valve 16 on a mouth pipeline on the left of in the of 1, acid solution cannot flow back to the first reversal valve, can only be through descaling bath assembly
The b chamber of 1 enters filter 17, and filter 17 may filter that the impurity in acid solution.Acid solution in filter 17 is through dead electricity
The second reversal valve under state, enters regulation valve 19, returns in storage acid tank 5.
Otherwise, when the first reversal valve and the second reversal valve obtain under electricity condition, acid solution is entered d by a mouth of descaling bath assembly 1
Mouth flows back to store up in acid tank 5.Therefore, electric control system 2 controls when the first reversal valve and the second reversal valve obtain dead electricity, can
Making acid solution change in the flow direction of descaling bath assembly 1, the frequency of its change depends on that reversal valve obtains dead electricity speed.Regulation valve 19
Aperture controlled by electric control system 2, acid solution flow velocity in pipeline is controlled by the aperture regulating valve 19, i.e. by

Blow down valve 6 entrance A3 is connected with compressed air gas source, opens and closes when electric control system 2 controls blow down valve 6, can
Controlling in compressed air entrance system, same compressed air commutates through the first reversal valve, to connecting line 14 and pickling
Discharged by the leakage fluid dram (B1 or B2) of tapping valve 15, owing to the first reversal valve changes after tubing 24 purging in groove assembly
To action, also can commutate in compressed air purging direction.
Electric control system 2 is according to the acid liquor temperature signal detected by temperature sensor 4 in storage acid tank 5 and densitometer 20
The concentration signal of detection, by the etching procedures set, determines pickling time, controls the first reversal valve and the second reversal valve
Commutation operating frequency, improves pickling efficiency.Electric control system 2, by the etching procedures set, can start acid pump 8 automatically
Or water pump 11, control acid pump 8 and the flow of water pump 11, the aperture of control and regulation valve 19, it is achieved automatically supply acid, for drift
Wash water and automatically adjust acid solution, washings flow and the function of flow velocity.Electric control system 2 presses the etching procedures set,
Can automatic open close blow down valve 6, tapping valve 15, it is achieved automatic blowing, by the residual acid solution in pipeline and water from tapping valve
(A1, A2, B1, B2 mouth) of 15 is discharged.
As shown in Fig. 2 descaling bath assembly structure chart, descaling bath assembly 1 comprises descaling bath 21, cover plate 22, tool mechanism
23, tubing 24.Descaling bath 21 is provided with two inlets (a, c) and two liquid outlets (b, d), acid solution inlet side
Determining to by the first reversal valve commutation, acid solution liquid outlet direction is determined by the second reversal valve commutation, can be in descaling bath 21
Change acid solution flow direction.Can place multi units tube material 24 in descaling bath 21, tubing 24 becomes phase end to end in descaling bath 21
Even arranged in series, tubing 24 quickly can assemble with tool mechanism 23.Tubing 24 can complete in descaling bath 21 pickling,
Rinse, the process of purging, then open cover plate 22 and can quickly remove tubing 24.
Such as the C direction view in Fig. 3 descaling bath assembly structure chart；Tool mechanism 23 is provided with the slot 25 of plurality of specifications size,
This slot 25 can be in close contact with plurality of specifications tubing 24, and slot 25 excircle is provided with multiple groove, these grooves
Can effectively prevent acid solution from entering in the space between slot 25 and tubing 24.
Tool mechanism 23 is provided with multiple section structure, uses, can realize in a pickling tubing 24 after assembling with tubing 24
Surface, pickling tubing 24 outer surface, simultaneously three kinds of pickling modes of pickling tubing 24 surfaces externally and internally.Such as Fig. 4, for
A pickling outer surface in descaling bath assembly structure chart, tool mechanism typical cross-sectional structure figure, tubing 24 inwall is blocked,
Acid solution can enter pickling tubing 24 outer surface from outside hole slot.Such as Fig. 5, for table inside and outside in descaling bath assembly structure chart
During the pickling simultaneously of face, tool mechanism typical cross-sectional structure figure, now tubing 24 inwall is open, and outside hole slot is open, acid
Liquid can be to the pickling simultaneously of tubing 24 inner and outer surfaces.Such as Fig. 6, during in descaling bath assembly structure chart pickling surfaces externally and internally,
Tool mechanism typical cross-sectional structure figure, now tubing 24 inwall is open, and without outside hole slot, acid solution can only be in tubing 24
Wall carries out pickling.
The above is only preferred implementation of the present utility model, it should be pointed out that: for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve
Also protection domain of the present utility model is should be regarded as with retouching.
