Conducting bar flushing device

Technical Field

The utility model belongs to the metallurgical field, concretely relates to electrically conductive washing unit that arranges.

Background

In the metal electrolytic refining process, because the electrolyte is the acid solution with larger concentration, acid mist exists in the electrolytic working environment, so that the phenomenon that the contact points of the cathode and the anode are oxidized by the acid mist is caused, the cell voltage is gradually increased along with the increase of the oxidation degree, the power consumption of the electrolytic operation is increased, the electrolytic efficiency is also reduced along with the increase of the production cost.

In order to solve the above problems, it is common to arrange for special operators to flush the conducting bars arranged on the cell edges with water. Taking an electrolysis workshop in the company of the applicant as an example, the electrolysis workshop is provided with 64 groups of electrolysis baths, each group comprises 18 electrolysis baths, and 1152 electrolysis baths in total, if the tops of the bath walls of all the electrolysis baths from beginning to end need to be washed by water, 4 people are arranged to carry out washing work each time, the washing work can be finished within about 1 hour, after washing, the contact points of a cathode and an anode are in good contact, the bath voltage is reduced immediately, acid mist in the environment still exists, the contact points of the cathode and the anode are oxidized gradually, the bath voltage is increased gradually, the washing process needs to be repeated, therefore, workers need to watch in turn on duty each day, the washing work is carried out once every 4 hours, the water consumption is about 100m per day³。

The method has low working efficiency and large labor capacity, and a large number of soft water pipes need to be arranged and repeatedly dragged in an electrolysis workshop, thereby bringing great inconvenience to other work; in particular, this method requires the consumption of large amounts of industrial water, and the flushing water is directly taken into the electrolyte, which also puts a great pressure on the electrolyte treatment system.

Detailed Description

The technical solution of the present application is further described below with reference to the accompanying drawings.

A water source pipeline 10 is connected with a nozzle 20, and the spraying direction of the nozzle 20 is consistent with the extending direction of a conductive bar arranged along the upper edge of a bath A.

Wherein, the water source pipeline 10 comprises a vertical pipe 11 arranged from bottom to top, the upper end of the vertical pipe 11 is a horizontal pipe 12 extending towards the direction of the conductive bar arranged on the electrolytic bath A, and the nozzle 20 is connected with the end of the horizontal pipe 12.

Preferably, a support rod 30 is disposed extending downwardly on the cross tube 12 adjacent the nozzle 20. Considering the environment factor in the electrolytic plant and when washing, the work load that frequent maintenance because of corroding can be avoided to the plastic pipe for the water pipe chooseing for use, because choose for use the plastic pipe, its rigidity is weaker, and the standpipe 11 can be to the reverse curved arc that is of injection direction and keep away from the displacement when nozzle 20 sprays water, will lead to the injection direction of nozzle to point to upwards squint like this. The problem is not solved, at first the contained angle of the free state between standpipe 11, violently pipe 12 is designed for 85 degrees and is slightly less than 90 degrees, add after having established bracing piece 30, under the supporting role of bracing piece 30, the contained angle between standpipe 11, violently pipe 12 is located 85 ~ 90 degrees, even the standpipe 11, violently pipe 12 have produced the bending moment in advance and have warp, just so can guarantee that the nozzle is when spraying the directional maintenance of the water spray of nozzle is unchangeable.

Further preferably, the lower end of the support rod 30 is positioned in a concave part of the groove which is concavely arranged upwards and downwards; or, the lower end of the support rod 30 is inserted and sleeved on the convex part arranged on the groove edge in an upward convex shape. The concave or convex parts are used for restraining the support rod 30 in the horizontal plane, so that the support rod is prevented from displacing on the surface of the electrolytic bath, and the stable spraying direction of the sprayed water is ensured.

Preferably, the water source pipeline 10 is provided with an electromagnetic throttle valve 40, the electrolytic cell voltage detection unit 50 collects cell voltage and transmits the cell voltage to the PLC 60, and the PLC 60 outputs a control signal to the electromagnetic throttle valve 40. The flow provided by the electromagnetic throttle valve 40 during operation can be adjusted in a limited and limited way, so that the falling position and time of the water flow sprayed by the nozzle 20 are realized; due to the long length of the cell, it is contemplated to provide nozzles 20 at each end of the electrical cell, thus ensuring that the conductive bars on the cell edge are flushed.

Specifically, when the tank voltage received by the PLC 60 is 6-8 v, a control signal is output to drive the electromagnetic throttle valve 40 to be opened, and the throttle opening of the electromagnetic throttle valve 40 is inversely proportional to the injection time.

Practical operation proves that the electrolytic plant has 64 groups of electrolytic cells, each group has 18 electrolytic cells, and 1152 electrolytic cells are used for washing the side cell wall of the electrolytic cell in the plant by adopting different washing methods, for example, the electrolytic plant described in the background art comprises the following steps: firstly, the traditional manual hose is adopted for sprinkling water for washing, and the average daily water consumption is 100m³4 persons are sprinkled with water for 6 hours every day; ② adopt the utility model discloses a washing unit, the groove voltage is on line set for 6V, when watering time length is 15s at every turn, about 12 times of watering about every day, about 2 hours water spraying washes one time promptly, the water consumption of washing at every turn is 2m³Average daily water consumption of 25m³The opening and closing of the electromagnetic throttle valve are automatically controlled by a PLC controller, and manual operation is not needed.

Compared with the traditional method, the conductive bar flushing device greatly saves industrial water consumption, reduces the pressure of an electrolyte treatment system, keeps the cell voltage in a lower state all the time, has higher electrolysis efficiency and more saves electricity, and simultaneously, the PLC control system automatically controls the electromagnetic throttle valve, saves a large amount of labor time and saves water cost and labor cost.
