Description

A new type of automatic flushing device for anode slime

technical field

The utility model belongs to the technical field of hydrometallurgy, and relates to an automatic flushing device for anode slime of a nickel electrolytic cell, in particular to a fast automatic flushing device for anode slime.

Background technique

In the soluble anode diaphragm electrolysis production process, with the continuous dissolution of metallic nickel in the anode, during the operation of unpacking the anode, part of the anode slime attached to the anode plate will fall into the bottom of the electrolytic cell due to operational reasons. Therefore, after 4 to 6 months of continuous production of each electrolytic cell, it must be cleaned, otherwise the anode slime will deposit too much. On the other hand, even harmful impurities in the anode slime will be electroplated on the cathode plate, which will seriously affect the current efficiency and product quality, resulting in many problems such as high energy consumption and poor quality.

The existing tank cleaning procedure is: multiple processes such as "lifting the cathode and anode plates, pumping and draining the electrolyte in the diaphragm bag, lifting the diaphragm bag, lifting the diaphragm frame, pumping and draining the electrolyte in the tank, and cleaning the anode slime"; the tank cleaning is completed It is also necessary to reinstall the diaphragm frame, diaphragm bag, cathode and anode plates in place, and refill the tank before production. All operations are done manually, and each tank cleaning operation takes about 24 hours, which seriously affects production efficiency, and more anode slime deposits will affect the quality of electrolytic nickel products.

Utility model content

In order to overcome the above-mentioned problems in the prior art, the purpose of this utility model is to provide a fast and efficient automatic washing device for anode slime. The anode slime can be quickly cleaned without taking out the diaphragm frame, which greatly shortens the cleaning time and labor intensity.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a new type of anode slime automatic flushing device, including a flushing pipe that goes deep into the electrolytic cell, a filter storage tank and a chute, and the flushing pipe is opened toward the bottom of the electrolytic cell. The water spray hole, the filter storage tank is below the lower slag outlet of the electrolytic tank, the filter screen is set in the filter storage tank, the storage tank wall under the filter screen is opened, the opening is connected to the drain pipe, the outlet of the drain pipe is connected to the chute, and the flushing pipe passes through the pipe Connect the infusion pump.

Further, the filter storage tank and the infusion pump are arranged on a movable operating platform.

Further, the outlet of the infusion pump is connected to a tee, one of the tees is connected to the bottom of the filter storage tank through a pipe, and a stop valve is set on the pipe; the other is connected to a tee, and one of the branches after the tee is connected to the flushing pipe. A pressure gauge, a shut-off valve and a shut-off valve are arranged on the connecting pipe, and the other is connected to the top of the filter screen, and a shut-off valve is arranged on the connecting pipe.

The water spray holes are set within 150° of the pipe section.

The flushing pipe is installed at a position 300mm close to the bottom of the tank body.

Beneficial effects of the utility model: it solves the problems of long cleaning time and high labor intensity in the existing tank, and at the same time solves the problems of high energy consumption and poor quality due to the large amount of anode slime deposition, which affects the current efficiency and product quality. Many questions. Since there is no need to clean the tank when cleaning the anode slime, it also saves the "lifting the cathode and anode plates, pumping and draining the electrolyte in the diaphragm bag, lifting the diaphragm bag, lifting the diaphragm frame, pumping and draining the electrolyte in the tank, and cleaning the anode slime" After multiple processes and tank cleaning, it is necessary to reinstall the diaphragm frame, diaphragm bag, cathode and anode plates in place, refill the tank and other processes, which greatly improves production efficiency and plays a role in stabilizing product quality. important role.

Description of drawings

Fig. 1 is the device schematic diagram of the present utility model.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The new anode slime automatic flushing device is shown in Figure 1, including a flushing pipe 1, a filter storage tank 2, a chute 3, etc. The flushing pipe 1 is provided with water spray holes facing the bottom of the electrolytic tank, and the filtering storage tank 2 is placed in the electrolytic tank. Below the lower slag opening, a filter screen 4 is set in the filter storage tank 2, an opening is opened on the storage tank wall below the filter screen 4, the opening is connected to the drain pipe 5, the outlet of the drain pipe 5 is connected to the chute 3, and the flushing pipe 1 is connected to the infusion pump through the pipe 6. The flushing pipe is installed 300mm close to the bottom of the tank. The spray holes are set within 150° of the pipe section. The filter storage tank 2 and the infusion pump 6 are arranged on the movable operating platform 7 .

The water outlet of the infusion pump 6 is connected with a tee, one of the tees is connected to the bottom of the filter storage tank 2 through a tube, and a shut-off valve J41-1 is arranged on the tube; 1 is connected, the connecting pipe is provided with a pressure gauge Y50, the stop valve J41-3, and the stop valve J41-4, and the other is connected to the top of the filter screen 4, and the connecting pipe is provided with a stop valve J41-2.

When in use, turn on the infusion pump 6 as shown in the figure, open the stop valve J41-3 and the stop valve J41-4 as shown in the figure, close the stop valve J41-1 and the stop valve J41-2, and open the bottom of the tank to lower the slag at the same time Butterfly valve D41-1 at the mouth, the flushing pipe will be filled with electrolyte with a certain pressure.
