Description
Technical Field
The utility model relates to an electrolytic copper foil production technical field, concretely relates to a structure that is arranged in electrolytic copper foil production process to pump electrolyte.
Background
In the electrolytic copper foil preparation process, a liquid storage tank for containing copper sulfate liquid is arranged in a pit, and a liquid supply pump is usually arranged on a ground zero plane due to limited space of the pit. In order to draw the copper sulfate liquid out of the liquid storage tank, a liquid suction mode that an inlet pipeline of a liquid supply pump extends into the bottom of the liquid storage tank to suck liquid is adopted during design, and a bottom valve is installed at the bottom of the pipeline. However, after the operation lasts for half a year or so, the pipelines at the inlet and the outlet of the liquid supply pump vibrate very severely, part of welded junctions of the pipelines are shaken to cause liquid leakage, and the problems of unstable flow, insufficient flow and the like can occur. The inspection shows that the inside of the bottom valve has damage or the inside of the valve has blocky sundries, crystals and the like, and the liquid supply pump operates normally after the bottom valve is cleaned or replaced. However, after a period of time, the problem occurs, and maintenance personnel need to regularly lift the inlet pipeline and the bottom valve by using the guide chain for maintenance, so that the normal production process is seriously influenced, and more equipment maintenance cost is generated.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to the shortcoming of prior art, provide a siphon jar structure that realizes that simple structure, suction electrolyte are more stable, can keep normal production better, suction electrolyte (like copper sulfate liquid) when being used for electrolytic copper foil production.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a siphon jar structure that suction electrolyte when being used for electrolytic copper foil production which characterized in that: the siphon device comprises a siphon tank, wherein a liquid inlet pipe is arranged in the siphon tank, and the liquid inlet pipe penetrates out of the siphon tank downwards and is inserted into a liquid storage tank; the lower part of the siphon tank is respectively provided with a liquid outlet pipe and a liquid discharge pipe, the liquid outlet pipe is connected with a liquid supply pump, the liquid supply pump is connected with a motor, and the liquid discharge pipe is provided with a liquid discharge valve; the siphon tank is provided with a water filling port which is communicated with the inside of the siphon tank and is provided with a valve.
Furthermore, a sieve plate is arranged at the upper part in the siphon tank, the sieve plate is fixedly connected with the inner wall of the siphon tank and the liquid inlet pipe, and sieve pores are uniformly arranged on the sieve plate, so that liquid flows uniformly.
Furthermore, a window is arranged on the side wall of the siphon tank and is higher than the sieve plate, so that the liquid level change condition in the tank can be observed conveniently during operation.
Further, the feed liquor pipe is vertically installed in the siphon tank, the bottom that it passed the siphon tank is connected to the liquid storage pot in, the upper portion of feed liquor pipe then is fixed through the sieve, and the upper end opening of feed liquor pipe is located the sieve top.
Furthermore, the water filling port is arranged at the top of the siphon tank, and liquid is filled into the siphon tank through the water filling port before operation.
Furthermore, the liquid outlet pipe and the liquid discharge pipe are respectively connected out from the lower part of the side wall of the siphon tank, copper sulfate liquid is pumped out by the liquid supply pump through the liquid outlet pipe, and the liquid in the siphon tank is emptied through the liquid discharge pipe after the system is stopped.
Preferably, the liquid inlet pipe, the liquid outlet pipe, the water injection port and the liquid discharge pipe are welded with the siphon tank to form a seamless structure, if a pipeline flange is involved, the pipeline flange also needs to be welded perfectly without weld defects, and the flange connection is sealed perfectly during operation.
When the pump is started to operate, the impeller of the liquid supply pump rotates, the electrolyte in the siphon tank is pumped through the liquid outlet pipe, the liquid level in the siphon tank is reduced in a short time, and the upper part of the siphon tank generates negative pressure vacuum. Because the liquid inlet pipe of the siphon tank is connected with the electrolyte in the underground liquid storage tank, the electrolyte in the liquid storage tank enters the liquid inlet pipe of the siphon tank under the action of atmospheric pressure and finally enters the siphon tank to supplement the liquid level of the siphon tank, continuous electrolyte flow is generated, and the operation of the electrolyte supply pump is stabilized.
The function of installing a bottom valve at the bottom of a pipeline in the past is as follows: when the centrifugal pump at a high position sucks liquid at a low position, the liquid inlet pipe is filled with the liquid, and the liquid can be pumped from the low position to the liquid inlet pipe. If the bottom end of the liquid inlet pipe is not provided with the bottom valve, after the pump stops, all liquid in the liquid inlet pipe flows back to the liquid storage tank. When the pump is started next time, the liquid inlet pipe is empty, so that the centrifugal pump cannot pump liquid; after the bottom valve is installed on the liquid inlet pipe, liquid in the liquid inlet pipe cannot flow back into the liquid storage tank after the pump is stopped because the bottom valve belongs to the one-way valve, and therefore normal work can be guaranteed.
The siphon tank is installed, and 80% of liquid can be retained at any time due to the water injection of the siphon tank. After the pump starts, can draw siphon jar interior liquid, and siphon jar other end inlet pipe stretches into below the stock solution jar liquid level, and the last cavity of siphon jar forms an inclosed space with the combination of feed liquor pipe like this. When a large amount of liquid in the siphon tank is pumped away, the upper cavity of the siphon tank generates a great negative pressure, so that water can be sucked from the liquid storage tank; after the liquid supply pump stops, although liquid in the liquid inlet pipe flows back to the liquid storage tank, water always exists in the siphon tank, and the closed space between the upper cavity and the liquid inlet pipe still exists, so that the next pump starting and liquid pumping cannot be influenced.
The utility model changes the configuration structure of the liquid pipeline of the electrolyte liquid feed pump for pumping the underground groove, so that a bottom valve does not need to be installed at the bottom of the liquid inlet pipeline, and the change of the local structure of the pipeline can play a role in protection, thereby reducing the cavitation corrosion phenomenon of an impeller and a pump shaft of the liquid feed pump caused by insufficient liquid pumping, effectively prolonging the service life of the liquid feed pump, and reducing the maintenance times and the maintenance cost of the liquid feed pump; the phenomenon that the impeller and the pump shaft are corroded and damaged due to the fact that the liquid supply pump can suck electrolyte unstably is improved, the number of times of overhauling the liquid supply pump by personnel is reduced, the labor intensity of the personnel is reduced, the problem that the liquid supply pump sucks the electrolyte unstably is finally eliminated, and the problem that the electrolyte stably supplies the liquid is improved.
