Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] The magnetic fluid sealing device of the mixer is installed at the main transmission position of the mixer. The sealing structure is composed of an inner ring and an outer ring. The bearing pressure plate 6 is installed above the high-speed spindle 1. The high-speed spindle 1 is vertically installed in the pillow block 2. The high-speed spindle 1 Install the pulley 8, high-speed bearing housing 9, gear 4, and pillow block 2 from top to bottom in sequence, and the small magnetic seal is installed above the pulley and on the temperature control wiring guide. There is a small magnetic fluid seal 7 and an electronic slip ring 10 on the upper part of the pulley 8; the bearing pressure plate 6 under the high-speed bearing seat 9 is located on the pillow block 2, and the medium magnetic fluid seal 5, the gear 4, and the large No. magnetic flu...

Abstract

The invention discloses a stirrer magnetic fluid sealing device. The stirrer magnetic fluid sealing device is composed of an inner ring and an outer ring, a high-speed main shaft is vertically arranged in a shaft table, a belt wheel is arranged at the top of the main shaft, a high-speed bearing block is arranged below the main driving belt wheel, and the upper part of the belt wheel is provided with a magnetic fluid seal III and an electronic slip ring; a bearing press plate under the high-speed bearing block is located on the shaft table, and a magnetic fluid seal II, a gear and a magnetic fluid seal I are sequentially arranged under the bearing press plate; the inner ring is arranged on the high-speed main shaft, an upper bearing and a lower bearing are arranged between the inner ring and the outer ring, and a hollow shaft is used as a mounting carrier; and O-shaped rings are arranged at the bottoms of the magnetic seals, and the sealing rings and the top of the hollow shaft form theseals. Compared with a traditional mechanical sealing structure, the stirrer magnetic fluid sealing device is characterized in that the structural elements are small and compact, installation is convenient, and the elastic force of an elastic element is replaced by the magnetic force, so that influences caused by a manufacturing error, an installation error and the axial displacement during working are avoided; and compared with a common sealing structure, the device is reliable in working, small in abrasion and long in service life.

Description

technical field [0001] The invention relates to production equipment for lithium-ion battery pole pieces, in particular to a magnetic fluid sealing device for a stirrer, which is used for [0002] Slurry production for the coating layer of battery pole pieces improves the stability of the slurry during stirring. Background technique [0003] In the existing production of slurry for the coating layer of lithium-ion battery pole pieces, most of the manufacturers' mixers use ordinary mechanical seals. The mechanical seal is mainly composed of a moving ring, a static ring, a cooling device, and a compression spring. The auxiliary parts include flexible graphite for the sealing ring, etc. The mechanical seal is a shaft seal device that relies on a pair or several pairs of end faces that are perpendicular to the shaft to slide relative to each other. Under the action of fluid pressure and the elastic force of the compensation mechanism, it is kept in place and equipped with auxil...
