[0016] Figure 1 It is a schematic structural diagram of the washing and filtering device provided in an embodiment of the utility model.
[0017] In the attached figure: 10, centrifuge; 20, slurry tank; 30, two-way pipe I; 31, feed valve I; 32, feed valve II; 40, two-way pipe II; 41, unloading valve for washing; 42, unloading valve for finished product; 50, waste water bucket; 60, conductivity meter; 70, centrifugal pump; DETAILED DESCRIPTION
[0018] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0020] The present invention will be further described below in conjunction with specific embodiments, but this is not intended to limit the present invention.
[0021] like Figure 1 As shown, the cobalt hydroxide washing and filtering device provided in the embodiment of the utility model includes a horizontal centrifuge body 10 and a slurry tank 20, and the slurry tank 20 is installed below the centrifuge body 10, and the feed port and the solid phase outlet of the centrifuge body 10 are respectively installed with a double-way pipe I30 and a double-way pipe II40, and the main pipes of the double-way pipe I30 and the double-way pipe II40 are respectively connected with the feed port and the solid phase outlet, and one of the branches in the double-way pipe II40 is connected with the feed port of the slurry tank 20 through a pipeline, and the discharge port of the slurry tank 20 is connected with one of the branches in the double-way pipe I30 through a pipeline.
[0022] Under the above structure, the cobalt hydroxide slurry enters the centrifuge body 10 from the other branch pipe in the two-way pipe I30 for solid-liquid separation. During the process, nitrogen enters the centrifuge from the nitrogen inlet in the centrifuge body 10. If the material is washed clean, it is discharged from the other branch pipe in the two-way pipe II40. If it does not meet the corresponding technical indicators, it is discharged into the slurry tank 20 through one of the branches in the two-way pipe II40. Pure water begins to enter from the slurry water inlet of the slurry tank 20, and then the stirring device is turned on to start slurrying. During the slurrying process, nitrogen enters from the nitrogen inlet on the slurry tank 20 to prevent oxidation. After the slurrying is completed, the material enters the centrifuge body 10 through the centrifugal pump 70 and one of the branches in the two-way pipe I30 in turn to continue dehydration until it meets the technical indicators and is opened to discharge the finished product.
[0023] In order to facilitate real-time monitoring of whether the material washing meets the requirements, a wastewater bucket 50 can be further installed on the liquid phase outlet of the centrifuge body 10 in the above-mentioned cobalt hydroxide washing and filtering device, and a conductivity meter 60 (such as a commercially available BECPOCKET conductivity meter) for detecting the conductivity of the wastewater can be installed in the wastewater bucket 50; under the above-mentioned structure, a drain valve can be further installed on the liquid phase outlet of the centrifuge body 10 to periodically or in real time put the washed salt-containing wastewater into the wastewater bucket 50, and then the salt-containing wastewater is quickly tested by the conductivity meter 60. If the conductivity does not meet the requirements, such as the conductivity is greater than 50, it is judged that the solid matter is not washed clean, and the material re-enters the slurry tank 20 for slurrying and then dehydrated and separated; if the conductivity meets the requirements, such as the conductivity is less than 50, the supporting PLC system instructs the centrifuge body 10 to perform solid-liquid separation, and the separated solid matter is discharged from the other branch pipe in the double-pass pipe II 40.
[0024] On the basis of this technical solution, in order to facilitate the control of each pipeline, a feed valve I31 is installed on the other branch of the two-way pipe I30, and a feed valve II32 is installed on one of the branches of the two-way pipe I30, so as to re-feed or send the slurried material into the centrifuge body 10 with the help of the feed valve I31 or the feed valve II32, thereby improving the use efficiency of the centrifuge body 10; similarly, a to-be-washed discharge valve 41 is installed on one of the branches of the two-way pipe II40, and a finished product discharge valve 42 is installed on the other branch of the two-way pipe II40, so as to discharge the product through the finished product discharge valve 42, or to discharge the material back into the slurry tank 20 with the help of the to-be-washed discharge valve 41.
[0025] The washing and filtering device provided in the present application adopts slurry circulation continuous washing, which greatly increases the daily processing of a single machine, can be applied to the needs of large-scale cobalt hydroxide production, and will not produce unqualified washing materials.
[0026] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of the present invention specification should be included in the protection scope of the present invention.
