Description

Technical Field

[0001] The utility model belongs to the field of anode bagging technology and anode chambers, in particular to an anode bagging anode chamber comprising a liquid level float. Background Art

[0002] During the nickel electrowinning process, oxygen evolution and acid generation reactions mainly occur on the surface of the insoluble anode. The acid generation reaction gradually increases the acidity of the electrowinning solution. The oxygen generated by the oxygen evolution reaction will enter the electrowinning plant along with the acid-containing steam during the dissipation process, causing a large amount of sulfuric acid mist to permeate the plant, causing the working environment of the nickel electrowinning plant to deteriorate seriously. At present, the anode bagging technology is used, that is, the anode plate is sealed in the anode liquid diaphragm bag, and an exhaust port is set on the anode liquid diaphragm bag to collect and treat the acid mist produced by the anode in a targeted, centralized manner, so as to solve the problem of poor working environment in the nickel electrowinning plant.

[0003] The anode bagging technology requires strict control of the anolyte level in the anode bag to ensure that the electrolyte can only flow from the cathode liquid with a higher level outside the diaphragm bag to the anode liquid with a lower level inside the diaphragm bag, and strictly control the acid in the anode liquid in the anode liquid diaphragm bag to prevent the anode liquid from seeping back and contaminating the cathode liquid. If the anode liquid diaphragm bag is damaged, the permeability of the diaphragm bag will increase (the permeation rate at the hole will increase), the anode liquid level will rise, and even the anode and cathode liquid levels will be the same. In this case, the anode liquid will seep back into the cathode liquid. How to monitor the anode liquid level (damage to the anode liquid bag) is a key technology that restricts the current development of anode bagging technology. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem of how to monitor the liquid level of the anolyte liquid in the absence of a related device for detecting the liquid level of the anolyte diaphragm bag at present.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An anode bag anode chamber including a liquid level buoy, including an anode liquid diaphragm bag, characterized in that a buoy rod is movably connected to the top of the anode liquid diaphragm bag, the lower end of the buoy rod is located inside the anode liquid diaphragm bag, the lower end of the buoy rod is connected to a float tank that can float on the anode liquid, the upper end of the buoy rod is located outside the anode liquid diaphragm bag, and the upper end of the buoy rod is connected to a buoy head.

[0007] A further technical solution is that a guide tube is provided on the top of the anode liquid diaphragm bag, the guide tube connects the inside and the outside of the anode liquid diaphragm bag, and the float rod is slidably connected inside the guide tube.

[0008] A further technical solution is that the float tank is made of plastic material and the inside of the float tank is hollow.

[0009] A further technical solution is that the buoy rod and the float tank are integrally formed.

[0010] A further technical solution is that the buoy head is plugged into the upper end of the buoy rod.

[0011] In summary, due to the adoption of the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: by movably connecting the float rod on the top of the anode liquid diaphragm bag, the lower end of the float rod is located inside the anode liquid diaphragm bag and is connected to a float tank that can float on the anode liquid, and the upper end of the float rod is located outside the anode liquid diaphragm bag and is connected to a float head. When the anode liquid level changes, the position of the float tank changes with the liquid surface position of the anode liquid, thereby driving the float head located outside the diaphragm frame to move up and down in the vertical direction to display the liquid surface position of the anode liquid, and utilizing the float tank to move up and down in the anode liquid. The buoyancy in the cathode liquid is transmitted through the float rod, and the red float head can accurately display the liquid level of the anode liquid in the diaphragm bag, which solves the key technology of monitoring the liquid level in the closed anode liquid diaphragm bag of nickel electrodeposition anode bagging technology. In this way, the liquid level of the anode liquid in the anode liquid diaphragm bag can be monitored relatively simply, thereby realizing the monitoring of the anode liquid level, which can facilitate the detection of changes in the anode liquid level. If the anode liquid level is found to have increased, it is necessary to check whether the anode liquid diaphragm bag is damaged as soon as possible, so as to detect and deal with it in time to avoid the cathode liquid being contaminated and affecting normal production.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-Figure 3 An anode bag anode chamber including a liquid level buoy includes an anode liquid diaphragm bag 5, characterized in that a buoy rod 3 is movably connected to the top of the anode liquid diaphragm bag 5, the lower end of the buoy rod 3 is located inside the anode liquid diaphragm bag 5, the lower end of the buoy rod 3 is connected to a float tank 4 that can float on the anode liquid, the upper end of the buoy rod 3 is located outside the anode liquid diaphragm bag 5, and the upper end of the buoy rod 3 is connected to a buoy head 1.

[0017] When in use, the float is mainly used to monitor the liquid level of the anode chamber. The nickel electrowinning anode bagging technology seals the anode in the anode liquid diaphragm bag 5, and needs to control the cathode liquid and the anode liquid to have a liquid level difference of 30-50mm to ensure that the cathode liquid can penetrate into the anode liquid diaphragm bag 5 by relying on the static pressure difference, and the anode liquid will not penetrate back into the cathode liquid. After the anode chamber is sealed, there is no way to observe the liquid level intuitively. If the anode liquid diaphragm bag 5 is damaged, the speed of the cathode liquid penetrating into the anode liquid diaphragm bag 5 will increase, the anode liquid level will increase, and the liquid level difference between the cathode and anode liquids will disappear. The anode liquid may penetrate back into the cathode liquid, and the acid in the anode liquid will contaminate the cathode liquid, affecting the cathode current efficiency in the electrowinning production process, and may even affect the physical appearance quality of the electrowinning nickel. By setting the anode chamber liquid level float on the anode diaphragm frame, the anode liquid level can be monitored at any time. If the anode liquid level is found to be rising, it is necessary to check whether the anode liquid diaphragm bag 5 is damaged as soon as possible, and it can be discovered and handled in time to avoid the cathode liquid being contaminated and affecting normal production. The main function of the float head 1 is to display the anode liquid level, so it is set to red to mark its liquid level with a striking color. When the anode liquid level changes, it can be discovered in time and disposal measures can be taken. The diameter of the float head 1 is larger than the inner diameter of the guide tube 2, and the diameter of the float tank 4 also needs to be larger than the inner diameter of the guide tube 2. This setting can ensure that after the float is installed, when there is no anode liquid in the anode liquid diaphragm bag 5, the float can also be fixed on the anode diaphragm frame.

[0018] A guide tube 2 is provided on the top of the anolyte diaphragm bag 5, and the guide tube 2 connects the inside and outside of the anolyte diaphragm bag 5, and the float rod 3 is slidably connected inside the guide tube 2. In order to make the float float up and down only in the vertical direction, the guide tube 2 is provided to fix and guide the float without affecting the float up and down. Since the liquid level difference between the normal and abnormal conditions of the anolyte is only 50mm, the vertical stroke of the float only needs to be slightly greater than 50mm.

[0019] The float tank 4 is made of plastic material, and the inside of the float tank 4 is hollow. The float tank 4 is made of plastic material, and it should be a small plastic tank that is hollow and complete (no tiny holes should appear to prevent the solution from filling the hollow space inside the float tank 4). Its material and internal hollow structure are both to obtain the maximum floating ability in the anode liquid and give full play to its function of detecting the liquid level with a float.

[0020] The buoy rod 3 and the float tank 4 are integrally formed. The buoy rod 3 and the float tank 4 are integrally formed to ensure that they are firmly connected and are a whole, so as to prevent the float tank 4 from falling off from the buoy rod 3, so that the buoy cannot monitor the liquid level and may mislead production. All parts of the buoy are made of plastic to avoid corrosion damage.

[0021] The buoy head 1 is plugged into the upper end of the buoy rod 3. The buoy head 1 is connected to the buoy rod 3 by plugging, which is convenient for installing the buoy.

[0022] The above are only preferred embodiments of the present invention.
