Abstract

The invention provides a stirrer upper cover assembly and a stirrer, and relates to the technical field of stirring devices. The upper cover assembly of the stirrer comprises an upper cover and a base plate, wherein the friction coefficient of the base plate is lower than that of the upper cover, and the base plate is detachably arranged on one side of the inner wall of the upper cover so as to shield a cleaning dead angle inside the upper cover. According to the upper cover assembly of the stirrer, the base plate is arranged on one side of the inner wall of the upper cover, and the base plate can be used for shielding the cleaning dead angle inside the upper cover, so that slurry is prevented from splashing and adhering to the cleaning dead angle of the upper cover, the cleaning dead angle of the upper cover is not required to be cleaned, the condition that metal scraps fall off due to scratching the inner wall of the cleaning dead angle of the upper cover is avoided, and the friction coefficient of the base plate material is lower than that of the upper cover material, so that slurry splashed onto the base plate is easy to clean, and dry material impurities are not generated to pollute the slurry.

Description

Mixer upper cover subassembly and mixer Technical Field The invention relates to the technical field of stirring devices, in particular to a stirrer upper cover assembly and a stirrer. Background The lithium battery production process needs to use the mixer to stir electric core thick liquids, and current mixer includes agitator tank and installs the stirring flabellum in the agitator tank to prevent thick liquids contact agitator tank inner wall and stirring flabellum, thereby reduce the interior iron element content of thick liquids, all plated the teflon layer on current agitator tank inner wall and the stirring flabellum. The top lid of agitator tank is equipped with the lid, and the lid inner wall of agitator tank has not plated the teflon layer usually, leads to thick liquids to splash and is difficult to the sanitization behind the clean dead angle of lid, not only can produce the drier impurity, and easily fish tail lid clean dead angle inner wall when the clean lid to lead to lid clean dead angle department to drop the metal fillings, pollute the thick liquids. Disclosure of Invention The invention aims to provide an upper cover assembly of a stirrer and the stirrer, which are used for relieving the technical problems that in the production process of lithium batteries in the prior art, battery core slurry in the stirrer is splashed to a cover body of a stirring tank and is difficult to clean after dead angles are cleaned, dry material impurities can be generated, and the inner wall of the dead angles are easy to scratch when the cover body is cleaned, so that metal scraps fall from the dead angles of the cover body, and the slurry is polluted. In a first aspect, the present invention provides a blender upper cover assembly comprising an upper cover and a backing plate; The friction coefficient of the material of backing plate is lower than the friction coefficient of the material of upper cover, backing plate demountable installation is in inner wall one side of upper cover to shelter from the inside clean dead angle of upper cover. In an alternative embodiment, the base plate is clamped with the upper cover. In an alternative embodiment, the upper cover is in a groove shape, the inner peripheral wall of the upper cover is provided with an annular clamping groove extending along the circumferential direction of the upper cover, and the outer edge of the backing plate is clamped in the clamping groove so as to shield a cleaning dead angle between the inner peripheral wall of the upper cover and the groove bottom.
