With the electrolytic solution liquid-inlet pipe of constrictor
Technical field
The present invention relates to the electrolytic solution input duct of electrolytic etching of metal refining, a kind of electrolytic solution liquid-inlet pipe with constrictor used in the electrolyzer of especially electrolytic solution " bottom in and top out " flow pattern.
Background technology
In electrolytic etching of metal workshop, electrolytic solution is in the middle of ceaselessly working cycle, and electrolytic solution often adopts the flow pattern of " bottom in and top out " enter or flow out electrolyzer.In this electrolyte circulation system, electrolytic solution liquid-inlet pipe enters from the outside of electrolyzer, walk around electrolyzer upper limb extends to electrolyzer diapire through electrolyzer inner side-wall, the electrolytic solution liquid-inlet pipe pressing close to diapire has opening, and the electrolytic solution in liquid-inlet pipe flows in electrolyzer from opening part.
In electrolysis production, for ensureing the balance of metal ion in electrolytic solution, electrolysis workman sporadically need regulate the switch of electrolytic solution liquid-inlet pipe, to control the flow of electrolytic solution in electrolyzer.But for saving production cost, electrolytic solution liquid-inlet pipe switch often uses ordinary ball valve switch, and common ball valve switch generally can not carry out flow rate fine-tuning.Therefore, electrolysis workman is when regulating flow of electrolyte, be difficult to by electrolytic solution liquid-inlet pipe switch rotary to suitable angle, when electrolytic solution liquid-inlet pipe switch aperture is excessive, electrolytic solution is rapidly from above-mentioned electrolytic solution liquid-inlet pipe opening part ejection, the anode sludge at the bottom of electrolytic bath is taken up, the anode sludge is attached to physical quality negative plate affecting electrolysis cathode, and, under the impact of high-voltage electrolyte, electrolytic solution liquid-inlet pipe likely departs from interface, shortens the work-ing life of electrolytic solution liquid-inlet pipe.
Summary of the invention
The invention provides a kind of electrolytic solution liquid-inlet pipe with constrictor, it is described by the problem that the excessive electrolysis cathode physical quality caused of flow of electrolyte declines or electrolytic solution liquid-inlet pipe departs from from interface above can solving.
The present invention is achieved through the following technical solutions above-mentioned purpose:
With the electrolytic solution liquid-inlet pipe of constrictor, comprise liquid-inlet pipe body and the electrolytic solution liquid-inlet pipe switch for controlling electrolytic solution liquid-inlet pipe electrolyte inside flow, the constrictor of restriction flow of electrolyte is also provided with in liquid-inlet pipe body, described constrictor is circular sheet-like structures, with hole in the middle part of constrictor, constrictor is located in the liquid-inlet pipe body pipeline at electrolytic solution liquid-inlet pipe switch rear.
The hole diameter of described constrictor is 10 ~ 15mm.
The invention has the beneficial effects as follows:
The present invention in electrolytic solution liquid-inlet pipe on constrictor is set, can limit electrolytic solution liquid-inlet pipe switch aperture excessive time flow of electrolyte, thus improve electrolysis cathode physical quality, extend the work-ing life of electrolytic solution liquid-inlet pipe.
Accompanying drawing explanation

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1 and Figure 2, with the electrolytic solution liquid-inlet pipe of constrictor, comprise liquid-inlet pipe body 3 and the electrolytic solution liquid-inlet pipe switch 1 for controlling electrolytic solution liquid-inlet pipe electrolyte inside flow, the constrictor 2 of restriction flow of electrolyte is also provided with in liquid-inlet pipe body 3, constrictor 2 is circular sheet-like structures, also with hole 4 in the middle part of constrictor 2, hole 4 diameter is 10 ~ 15mm, and constrictor 2 is located in the pipeline of electrolytic solution liquid-inlet pipe switch 1 rear liquid-inlet pipe body 3.
Under normal circumstances, electrolytic solution in liquid-inlet pipe body 3 enters electrolyzer through constrictor 2 gently, when mineral ion imbalance in electrolytic solution or other reasons need to increase electrolyte flow rate, rotary electrolysis liquid liquid-inlet pipe switch 1, increase the aperture of electrolytic solution liquid-inlet pipe switch 1, due to the restriction of hole 4 in the middle part of limited flow 2, flow of electrolyte slowly increases, even if the aperture of electrolytic solution liquid-inlet pipe switch 1 has exceeded pre-determined range, flow of electrolyte also can not sharply increase, thus ensure that carrying out smoothly of electrolysis production.
