Embodiment 1

[0041] First, as figure 1 As shown, an air inlet and air return nozzle assembly 3 is used for blowing to a cylindrical roller body 1, including five air inlet nozzle assemblies 2 and four air return nozzle assemblies 3, and all air inlet nozzle assemblies 2 blow out in parallel. The plane where the wind is located and the planes where the parallel air inhaled by all the air return nozzle assemblies 3 are all intersected on the axis of the roller body 1, and the air outlet surface of the air inlet nozzle assembly 2 and the air inlet surface of the air return nozzle assembly 3 are in harmony with the roller body. 1 The coaxial cylindrical surfaces are tangent, and the air inlet nozzle assembly 2 and the air return nozzle assembly 3 are arranged at intervals. Its function is that the cold air blowing on the cylindrical casting roll through the air inlet nozzle assembly 2 can be blown along the radial direction of the casting roll through the setting of the outlet of the air inlet...

Abstract

The invention discloses an air inlet and return nozzle assembly and an efficient cooling device for the back face of a lithium ion battery diaphragm. Firstly, the air inlet and return nozzle assembly is used for blowing to a roller body and comprises an air inlet nozzle assembly and an air return nozzle assembly, and the air outlet face of the air inlet nozzle assembly and the air inlet face of the air return nozzle assembly are both tangent to a cylindrical face coaxial with the roller body; the air inlet nozzle assemblies and the air outlet nozzle assemblies are arranged at intervals. On the second aspect, the efficient cooling device for the back surface of the lithium ion battery diaphragm comprises a shell, a ventilation opening is formed in the shell, the air inlet and return nozzle assembly is arranged in the ventilation opening, the shell is communicated with an air inlet pipe and an air return pipe, and the interior of the shell is divided into an air inlet cavity and an air return cavity through a partition plate. The cooling rate of the back face of the sheet in the cooling process can be increased, the cold air speed and temperature borne by the sheet in the cooling process are evenly distributed, and therefore the poor product phase separation effect is avoided.

Description

technical field [0001] The invention relates to the technical field of lithium ion battery diaphragm processing, in particular to an air intake and air return nozzle assembly and a high-efficiency cooling device for the back of the lithium ion battery diaphragm. Background technique [0002] At present, in the process of wet lithium-ion battery separator processing, the phase separation process has a particularly critical impact on the quality of the entire product. The phase separation process occurs in the casting process, and the cooling effect of the sheet in this process directly affects the two-phase separation rate, thereby affecting the performance indicators of the product. The traditional sheet casting machine cools the sheet by winding the sheet on the cooling casting roll to cool the side facing the casting roll. Generally, only one side of the sheet can be continuously cooled, but the cooling time of the back is short. [0003] With the increase of production c...
