Description

Technical Field

[0001] This utility model relates to the technical field of slurry dispersion equipment, and in particular to a slurry dispersion equipment for carbon nanotubes. Background Technology

[0002] Carbon nanotubes possess higher electronic conductivity, which is beneficial for improving the capacity and cycle life of lithium-ion batteries. Therefore, carbon nanotubes have broad application prospects in lithium-ion battery applications. However, when preparing carbon nanotube conductive slurries, the slurries are quite viscous and easily remain on the stirring rod, making them difficult to slide off. This usually requires manual cleaning of the stirring rod, which is time-consuming and labor-intensive. Chinese patent document CN202022460893.1 discloses a dispersion device for a large specific surface area carbon nanotube conductive slurry. This application uses a cleaning block on the stirring rod, and then manually presses down the extrusion layer and the cleaning block, using a limiting wiping block to clean the surface of the stirring rod. In this application, the cleaning block is connected to the stirring rod by a sliding connecting block. During the high-speed rotation of the stirring rod, the cleaning block can move on the stirring rod and eventually fall into the dispersion cylinder, affecting the slurry quality. Furthermore, during dispersion, some slurry can easily splash upwards onto the cleaning block. Since the bottom of the cleaning block is horizontally set, the slurry may flow upwards to the extrusion layer during cleaning, increasing the cleaning difficulty. Utility Model Content

[0003] To address the aforementioned problems, this invention discloses a dispersion device for carbon nanotube slurry, which solves the issues of the inconvenience of cleaning the stirring rod in existing dispersion devices and the potential for existing cleaning devices to interfere with the normal operation of the dispersion device.

[0004] The specific technical solution is as follows:

[0005] A dispersion device for carbon nanotube slurry includes a disperser body, a rotating shaft seat on the disperser body, a stirring rod rotatably mounted in the rotating shaft seat via a bearing, a guide sleeve extending downward from the center of the bottom end of the rotating shaft seat, the guide sleeve being fitted over the stirring rod with a gap, the bottom of the guide sleeve being tapered and inclined; a rotating sleeve rotatably mounted at the bottom end of the rotating shaft seat outside the guide sleeve, a cleaning block threadedly connected to the inner side of the rotating sleeve, the cleaning block including a fixing ring and an elastic tensioning seat, the elastic tensioning seat consisting of several ring-shaped tensioning elements and elastic rings fitted over the outer sides of the tensioning elements, the upper ends of the tensioning elements being fitted with the elastic rings, and adjacent tensioning elements being elastically connected. The elastic tensioning seat is tightly fitted under the clamping action of the elastic ring, making the upper end of the elastic tensioning seat a hollow cylindrical structure that fits tightly against the surface of the stirring shaft, and the lower end of the elastic tensioning seat an inverted bucket-shaped structure to prevent slurry splashing; the fixing ring is sleeved on the outer side of the upper end of the elastic tensioning seat, and the fixing ring is slidably connected to each tensioning component, allowing the tensioning component to move radially on the fixing ring; the outer wall of the fixing ring is threaded and used to connect with the inner wall of the rotating sleeve, realizing the lifting and lowering of the cleaning block, and the top of the elastic tensioning seat is tapered and inclined, cooperating with the bottom of the guide sleeve, so that the lifting and lowering of the cleaning block and the cooperation between the top of the elastic tensioning seat and the guide sleeve realize the expansion and contraction of the elastic tensioning seat.

[0006] Furthermore, the tensioning member includes a sleeve portion and a stop portion disposed at the lower end of the sleeve portion. The outer wall of the sleeve portion is provided with a groove for installing an elastic ring, and the inner wall of the top end of the stop portion is arc-shaped.

[0007] Furthermore, several sets of guide rods are evenly distributed circumferentially on the inner wall of the fixed ring. The direction of each set of guide rods is respectively arranged along the radial direction of the fixed ring. Several guide holes for the insertion of guide rods are opened on the sleeve part of the tensioning member. Through the cooperation of guide rods and guide holes, each tensioning member moves radially on the fixed ring and realizes the expansion and contraction of the elastic tensioning seat.

[0008] Furthermore, the bottom end of the inner wall of the rotating sleeve is flared to form a receiving groove for accommodating the upper end of the baffle part.

[0009] Furthermore, the lower end of the baffle is arranged longitudinally, and both the outer wall of the lower end of the baffle and the outer wall of the rotating sleeve are provided with anti-slip textures for gripping.

[0010] Furthermore, the elastic ring is an elastic rubber ring.

[0011] The beneficial effects of this utility model are reflected in:

[0012] (1) In this utility model, the cleaning block is fitted with an expandable and contractible elastic tensioning seat on the stirring rod. During cleaning, the elastic tensioning seat is tightly attached to the surface of the stirring rod under the action of the elastic ring, and then pressed down to scrape off the conductive slurry on the stirring rod. During stirring, the cleaning block is fixed to the rotating sleeve by the fixing ring. During the rising process, the guide sleeve and the conical surface of the sleeve cooperate with each other, so that each tensioning element moves outward and the elastic tensioning seat expands to avoid contact with the stirring rod, so that the cleaning block can be stably fixed in the rotating sleeve, effectively avoiding the cleaning block from interfering with the stirring rod.

[0013] (2) The bottom of the cleaning block adopts an inverted bucket-shaped structure, which prevents the slurry from being scraped off the stirring rod and splashing onto the operator's hands during the cleaning process, thus increasing the cleaning difficulty. Attached Figure Description
