Description

Technical Field

[0001] The utility model relates to the technical field of waste battery recycling equipment, in particular to a nickel-cobalt cleaning and separating tank. Background Technique

[0002] In the wet treatment technology of waste power battery cathode waste, nickel, cobalt and manganese are mainly transferred into the solution in the leaching stage, and then valuable metals are separated from the solution. In the existing process technology, chemical precipitation, solvent extraction and other methods are mainly used to separate and extract nickel, cobalt and manganese from the solution. These methods can achieve the separation and extraction of nickel, cobalt and manganese, but each separation requires cleaning. In the existing cleaning equipment, such as the prior art with the publication number of CN211546671U, since the nickel and cobalt filter residues all flow downward along the screen, every time a kind of filter residue is separated, the screen needs to be cleaned before the new filter residue enters. However, in the existing technology, multiple filter residues are on one screen. If the screen is not cleaned thoroughly, it will lead to the problem of valuable metals being mixed together. Content of the Utility Model

[0018] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

[0019] Please refer to Figures 1-5, an embodiment provided by the present utility model: a nickel-cobalt cleaning and separation tank, comprising a tank body 1; a feed inlet 2 is provided on one side of the tank body 1, and a drain pipe 4 is further provided at the bottom of the tank body 1; a screen 5 is arranged inside the tank body 1, and the screen 5 is movably installed in the tank body 1, and a cleaning assembly 3 is installed at the upper opening of the tank body 1; the cleaning assembly 3 includes a cover plate 30, a driving motor 32 is arranged on the upper surface of the cover plate 30, and a driving shaft 31 is driven to rotate through the driving motor 32, so as to cause the paddle 36 arranged at the bottom of the driving shaft 31 to rotate on the bottom surface of the screen 5, thereby separating the water and valuable metals of the filter residue.

[0020] In summary, since the screen 5 is movably installed inside the tank body 1, whenever the type of filter residue changes, a new screen 5 can be replaced to solve the phenomenon that valuable metals are mixed together; at the same time, the screen 5 is convenient to disassemble and install, so it is also convenient to thoroughly clean the screen, thereby improving the purity of valuable metals; in particular, the device uses the rotation of the paddle 36 to cause the valuable metals in the filter residue to roll on the screen 5, improving the separation speed of valuable metals and water.

[0021] In addition, the screen 5 is placed in the middle of the tank body 1. First, it is convenient to use the screen 5 to receive the filter residue; second, it is convenient for the water in the filter residue to flow downward quickly; third, the tank body is relatively sealed to avoid the problem that the filter residue splashes outwards or is contaminated by external impurities during the separation process.

[0022] Furthermore, since a spray head support 35 is also arranged on the surface of the cover plate 30 facing the tank body 1 and is connected and communicated with the external cleaning liquid through a connecting pipe 34 provided, therefore, the cleaning liquid can be introduced into the spray head support 35 through the connecting pipe 34 and then sprayed out by the spray heads on the spray head support 35, and then the rolling filter residue can be rinsed to improve the cleanliness of the valuable metals.

[0023] Even further, since the connecting pipe 34 passes through the cover plate 30 and is connected to a nut 37 provided, therefore, tightening the nut 37 expands the gap between the spray head support 35 and the bottom surface of the screen 5; conversely, loosening the nut 37 can also reduce the gap between the bottom surface of the screen 5 and the spray head support 35, so the impact force of the spray head on the filter residue can be adjusted by the gap, and thus the cleanliness of the valuable metals can be further improved.

[0024] In addition, since the number of the connecting pipes 34 is two, therefore, when one of them is connected to the cleaning liquid and the other is connected to the compressed air pipeline, the valuable metals can be dried by the compressed air after being rinsed.

[0025] Based on the above solution, since a support platform 6 is further provided on the inner wall surface of the tank body 1, and the upper edge of the screen mesh 5 is located on the support platform 6, therefore, while facilitating the smooth removal and installation of the screen mesh 5, the stability of the screen mesh 5 after installation can also be ensured.

[0026] Further, since a lifting hook 33 is further provided on the cover plate 30, the cleaning assembly 3 can be lifted by the lifting hook 33, so as to facilitate the user to remove the screen mesh 5 or install the screen mesh 5 inside the tank body 1.

[0027] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present invention.
