Dispersing, mixing and drying device

Abstract

The invention discloses a dispersing, mixing and drying device, comprising a stand, a vibration exciter mounted on a base of the stand, an electric motor driving the vibration exciter to operate, and a grinding barrel located inside the stand and mounted on the base of the stand via a vibration reduction spring. The grinding barrel is filled with grinding medium therein, the vibration exciter acts on the grinding barrel, the grinding barrel can be vacuumized or be used for heating and cooling the medium therein via a jacket arranged at the periphery of the grinding barrel. The materials at a discharging hole can be circularly fed into a feeding hole repeatedly via a material pipeline to be mixed and dispersed. The invention can enable the materials to be evenly dispersed and dried within a short time so that a desired crushing result is achieved.

Description

technical field

[0001] The invention relates to a dispersion mixing drying equipment, in particular to a dispersion mixing drying equipment of battery materials. Background technique

[0002] Power batteries are widely used in various fields, especially in recent years with the development of electric vehicle industry, more and more attention has been paid to power batteries, and its safety performance has always been the focus of attention of various manufacturers and users, and the consistency of battery performance Safety is the fundamental issue of its safety performance, which includes the consistency of raw materials for manufacturing battery active materials and the consistency of battery active materials produced from raw materials. To ensure their consistency, the first problem is to ensure that they are mixed evenly. Traditional methods use conical mixers or V-shaped mixers to mix materials. There are original mixing methods, poor mixing effects, low mixing efficie...

Examples

specific Embodiment 1

[0023] A kind of dispersing and mixing drying equipment, including a frame 1, a vibrator 2 installed on the base of the frame 1, a motor 6 for driving the vibrator 2, and a motor 6 located in the frame 1 and installed on the frame through a vibration damping spring 3 1. A grinding barrel 4 on the base, the grinding barrel 4 has a grinding medium 5 inside, and the vibration exciter 2 acts on the grinding barrel 4.

[0024] A material circulation pipeline 7 is connected between the discharge port 13 and the feed port 12 of the mill barrel 4. After the material 11 enters the mill barrel 4 from the feed port 12, it interacts with the grinding medium under the action of excitation and is dispersed. And pulverize, then come out from the discharge port 13, the qualified ones are sent to the next production step, and those that need to be further dispersed and crushed will enter the grinding barrel 4 again from the above-mentioned material circulation pipeline 7 through the feed port 1...

specific Embodiment 2

[0029] Start the equipment in specific embodiment 1, adjust the equipment parameters, add 100Kg of material with uneven thickness and particles no greater than 30um from the feed port 12, start vacuum pumping and excitation, and after 30 minutes of vibration, the discharge port 13 start discharging, the sample is taken as a sample every 20Kg, and 5 samples are taken for testing, and the results are as follows:
