Abstract

The invention discloses a stirrer, wherein, a stirring drum adopts a U-shaped structure that is arranged vertically; an opening is formed at the top of the stirring drum; a stirring shaft vertically extends into the inner part of the stirring drum through the opening formed at the top of the stirring drum from outside to inside; the lower end of the stirring shaft is fixedly connected with blades through connection cross rods, and each blade is arranged vertically and is U-shaped; each gap formed between the outer wall of the U-shaped structure of each blade and the inner wall of the U-shaped structure of the stirring drum ranges from 1 to 2 mm; the blades are arranged in the axial direction of the stirring shaft at intervals, and the number of the blades ranges from 2 to 5; in addition, the blades are uniformly distributed in the circumferential direction of the stirring shaft, and the number of the blades ranges from 3 to 6. Stirring dead areas do not exist in areas close to the stirring shaft and the bottom of the stirring drum; the stirring shearing force is strong; larger stirring coverage area can be ensured; and the stirrer has the advantages of simple structure, no stirring dead area, uniform stirring and sufficient stirring capacity, and is convenient to maintain.

Description

A kind of agitator

Technical field

The present invention relates to new forms of energy production equipment field, particularly be used to stir the raw materials for production of lithium battery, the agitator that raw materials for production are mixed.

Background technology

Current, lithium battery is extensively used with distinctive performances such as its operating voltage is high, energy density is big, self-discharge rate is low, memory-less effects.But along with the progress of science and technology, novel electron Equipment of Development such as notebook computer, digital camera, mobile phone, medicine equipment and LEO satellite and high orbit synchronous satellite are had higher requirement to the lithium battery industry.And the R and D of lithium battery mainly concentrate on the relevant active material, and the performance of battery composition material and preparation technology have determined the lithium battery performance to a great extent.What the lithium battery active material prepared most critical in the process is agitator.

Agitator commonly used comprises each parts such as reductor, frame, shaft, axle envelope; The lithium battery raw material belongs to a kind of full-bodied fluid in whipping process; And the modular construction of agitator commonly used is single; Even the structure of multistage multilayer also is simple repeated processing structure, exist stirring not thoroughly, be prone to stay dead angle, area coverage is little, power consumption is big shortcoming.

Summary of the invention

The objective of the invention is for overcoming the deficiency of above-mentioned existing agitator, a kind of agitator that is specially adapted to the processing of lithium battery raw material is provided, can realize the stirring of uniform and complete full-bodied fluid.

The technical scheme that the present invention adopts is: comprise shaft and mixing drum; Mixing drum is the U type structure of vertically placing; Opening is arranged at the top of mixing drum; Shaft vertically extends mixing drum inside at the top open part ecto-entad of mixing drum, and the lower end of shaft is through connecting the blade that cross bar is fixedly connected the U type structure of vertically placing, and the gap between the inwall of the outer wall of the U type structure of blade and the U type structure of mixing drum is 1～2mm; Along axially going up at interval of shaft 2～5 blades are set, along being uniformly distributed with 3～6 blades on the circumferencial direction of shaft.

All there is not the stirring blind area in the present invention in zone and mixing drum bottom near shaft; The stirring shearing force is strong; Can guarantee bigger stirring area coverage, have simple in structure, maintenance is convenient, stir can not stay the dead angle, stir, advantage that stirring capacity is sufficient.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain.

Fig. 1 is a structure chart of the present invention;

Among the figure: 1. shaft; 2. mixing drum; 3. blade; 4. connection cross bar.

The specific embodiment

Referring to Fig. 1, the present invention includes shaft 1, mixing drum 2, blade 3 and be connected cross bar 4, mixing drum 2 is the U type structures of vertically placing, and opening is arranged at the top of mixing drum 2, and the bottom is a circular arc.Shaft 1 vertically stretches into mixing drum 2 inside at the top open part ecto-entad of mixing drum 2, is fixedly connected blade 3 in the lower end of shaft 1, is fixedly connected through connecting cross bar 4 between blade 3 and the shaft 1.Shaft 1 adopts stainless steel tube to process, can anti-solvent corrosion.

Blade 3 also is the U type structure of vertically placing; Make the outer rim shape of blade 3 consistent with the inwall of mixing drum 2; Gap between the inwall of the outer wall of the U type structure of blade 3 and the U type structure of mixing drum 2 is very little; Be 1～2mm, can remove and be attached to the viscous reaction product on mixing drum 2 inwalls or be piled up in the solids on mixing drum 2 diapires.

The present invention can be provided with 2～5 blades 3 along axially going up at interval of shaft 1 according to the requirement according to technology, and on the circumferencial direction of shaft 1, along being uniformly distributed with 3～6 blades 3 on the circumferencial direction of shaft 1.The mode that adopts multi-layer and multi-directional to shear stirs full-bodied lithium battery raw material.
