Problems solved by technology
[0002] When processing the positive electrode material of the battery, spray drying equipment is used to dry the slurry. In the current processing process, it is found that the modular nozzle installed on the upper end of the spray drying tank will be blocked by the slurry during use. Therefore, in order to clean the nozzle, a long downtime for maintenance and repair is required, which will take a long time

Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0015] Such as Figure 1-3 As shown, a spray drying system for the preparation of battery cathode materials in the present invention includes a spray drying tank 17, and the top of the spray drying tank has an opening 1 with a vertical structure, and it is characterized in that the outside of the opening is set by a bracket 16. There are two guide grooves 2, a first spray drying nozzle module 3 and a second spray drying nozzle module 4 are installed between the guide grooves, and the outer sides of the first spray drying nozzle module and the second spray drying nozzle module are respectively connected Driving mechanism. It includes a first driving mechanism 9 and a second driving me...

The invention discloses a spray drying system for preparing battery cathode materials. The spray drying system comprises apray drying tank; an opening with a vertical structure is formed in the top ofthe spray drying tank; two guide grooves are formed in the outer side of the opening; a first spray drying nozzle module and a second spray drying nozzle module are mounted between the guide grooves;the outer side of the first spray drying nozzle module and the outer side of the second spray drying nozzle module are respectively connected with a driving mechanism, so that the first spray dryingnozzle module and the second spray drying nozzle module are driven to move linearly along the guide grooves to get matched with or separated from the opening in a sealed mode, and therefore spray drying nozzle rapid replacing can be realized. By means of the technical scheme, the opening of the spray drying tank can be matched with the first spray drying nozzle module and the second spray drying nozzle module, sealing fit or separation is achieved, and therefore rapid replacement is achieved through driving by the driving mechanism.
Description
technical field [0001] The invention relates to the technical field of battery cathode material processing, in particular to a spray drying system for preparing battery cathode materials. Background technique [0002] When processing the positive electrode material of the battery, spray drying equipment is used to dry the slurry. In the current processing process, it is found that the modular nozzle installed on the upper end of the spray drying tank will be blocked by the slurry during use. Therefore, in order to clean the nozzle, a long downtime for maintenance and repair is required, which will take a long time. Contents of the invention [0003] The purpose of the present invention is to provide a spray drying system for the preparation of battery positive electrode materials aiming at the technical defects existing in the prior art. [0004] The technical scheme adopted for realizing the purpose of the present invention is: [0005] A spray drying system for the pre...
