With the electrolytic solution liquid-inlet pipe of constrictor
Technical field
The present invention relates to a kind of electrolytic solution liquid-inlet pipe with constrictor using in the electrolyzer of electrolytic solution input duct, especially electrolytic solution " bottom in and top out " flow pattern of electrolytic etching of metal refining.
Background technology
In electrolytic etching of metal workshop, electrolytic solution is in the middle of working cycle ceaselessly, and electrolytic solution often adopts the flow pattern of " bottom in and top out " to 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 of pressing close to diapire has opening, and the electrolytic solution in liquid-inlet pipe flows in electrolyzer from opening part.
In electrolysis production, be the balance that ensures metal ion in electrolytic solution, electrolysis workman needs not timing and regulates 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 in the time regulating flow of electrolyte, be difficult to electrolytic solution liquid-inlet pipe switch rotary to arrive suitable angle, in the time that 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 the physical quality that affects electrolysis cathode on negative plate, and, under the impact of high-voltage electrolyte, electrolytic solution liquid-inlet pipe likely departs from interface, has shortened 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 can solve the described problem being departed from from interface by the excessive electrolysis cathode physical quality decline causing of flow of electrolyte or electrolytic solution liquid-inlet pipe above.
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 for controlling the electrolytic solution liquid-inlet pipe switch of electrolytic solution liquid-inlet pipe electrolyte inside flow, in liquid-inlet pipe body, be also provided with the constrictor of restriction flow of electrolyte, described constrictor is round sheet structure, constrictor middle part is with hole, and 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 arranges constrictor in electrolytic solution liquid-inlet pipe, can limit the flow of electrolyte of electrolytic solution liquid-inlet pipe switch aperture when excessive, thereby improve electrolysis cathode physical quality, has extended the work-ing life of electrolytic solution liquid-inlet pipe.
Brief description of the drawings
Fig. 1 is the structure iron of the present invention while working.
Fig. 2 is the front view of constrictor of the present invention.
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 for controlling the electrolytic solution liquid-inlet pipe switch 1 of electrolytic solution liquid-inlet pipe electrolyte inside flow, in liquid-inlet pipe body 3, be also provided with the constrictor 2 of restriction flow of electrolyte, constrictor 2 is round sheet structure, constrictor 2 middle parts are also with hole 4, and hole 4 diameters are 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, in the time that metal ion in electrolytic solution is unbalance 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 limited flow 2 middle part holes 4, 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 sharply not increase, thereby has ensured carrying out smoothly of electrolysis production.
