Abstract
LiFePO4 ball mill is prepared the utility model discloses one kind, this, which prepares LiFePO4 ball mill, includes motor and the sand cylinder coaxially connected with motor, the face of cylinder of the sand cylinder is interior, outer double-layer structure, spiral bar is provided with the sand cylinder internal layer inwall, the spiral bar axially offers some correspondence breach along sand cylinder, in the sand cylinder, sound-absorbing material layer is provided between outer layer, the sand cylinder end face is provided with one-way exhaust valve, the one-way exhaust valve is 1st/1st to three/2nd of sand cylinder internal layer internal diameter apart from the minimum range of sand cylinder internal layer inwall.The utility model one kind prepares LiFePO4 with ball mill by setting spiral bar in sand cylinder internal layer inwall and setting sound-absorbing material between its inside and outside two layers, the axial mobility of material can effectively be increased, so that grinding batch mixing is more uniformly distributed and absorbed the noise in sand cylinder, the gas produced during simultaneously by one-way exhaust valve come effluent abrasive lapping, can improve the security that equipment is used.
Description
Technical field
The utility model is related to a kind of Preparation equipment of LiFePO4, and more particularly to one kind prepares LiFePO4 ball milling
Machine.
Background technology
LiFePO4 is mainly used in various lithium ion batteries, and its crystal structure is olivine structural, with the safe, longevity
Order length, the good characteristic such as energy density height, thus be widely used in energy storage device, it is electric tool, lightweight electric powered vehicles, small-sized
The numerous areas such as equipment.
In the preparation process of LiFePO4, grinding batch mixing is a very important link, is often needed in this link
Use ball mill, but existing horizontal ball mill is mainly sand cylinder and horizontally rotates to drive abrasive body to grind material
Mill, such that material is difficult axial flowing, so as to the problem of grinding batch mixing is uneven occur；Existing ball mill is ground simultaneously
Mill tube is Seal Design, and ferric phosphate, lithium carbonate and auxiliary material can decompose generation gas, so meeting when grinding is heated or is collided
So that chamber pressure is raised, material splash from gland gap may finally occur and come out, so that damaging equipment and wound
And workman；Other sand cylinder in the running, because the friction or shock between abrasive body and sand cylinder inwall can send larger
Noise, so that larger noise pollution can be produced.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and prepares LiFePO4 ball mill, and it grinds batch mixing
Uniformly, safe, operation noise is small.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：
One kind prepares LiFePO4 ball mill, including motor and the sand cylinder coaxially connected with motor, institute
The face of cylinder for stating sand cylinder is to be provided with spiral bar, the spiral bar edge on inside and outside double-decker, the sand cylinder internal layer inwall
Sand cylinder axially offers and is provided with sound-absorbing material layer, the sand cylinder between some correspondence breach, the inside and outside layer of sand cylinder
End face is provided with one-way exhaust valve, and the one-way exhaust valve is in sand cylinder internal layer apart from the minimum range of sand cylinder internal layer inwall
/ to three/2nd of footpath.By being provided with spiral bar on sand cylinder internal layer inwall, so it is easy to material in grinding
When moved axially along spiral bar so that add material axial mobility so that its grind batch mixing it is more uniform；It is logical
Cross and some correspondence breach are axially offered along sand cylinder in spiral bar, be so easy to discharge during Flow of Goods and Materials to indentation, there, keep away
Exempt from axial barrier；By being provided with sound-absorbing material layer between the inside and outside layer of sand cylinder, so effectively inhaled using sound-absorbing material
Friction or the energy hit between mill ball and sand cylinder inwall are received, to reach the effect of reduction noise；By at sand cylinder end
Face is provided with one-way exhaust valve, is so both easy to discharge the material gas produced in grinding, to reduce the pressure in sand cylinder
Power, prevents material from, along the splash of gland gap, effectively can prevent outside air from entering in sand cylinder again；While one-way exhaust
Valve is 1st/1st to three/2nd of sand cylinder internal layer internal diameter apart from the minimum range of sand cylinder internal layer inwall, is so both easy to
The gas produced during more efficient quick effluent abrasive lapping, can avoid causing one-way exhaust valve to block again.
Preferably, the cross section of the spiral bar is semicircle shape, it can so be prevented effectively from sand cylinder inwall and material occur
Accumulation, while being also convenient for barrel cleaning.
Preferably, some gap widths of the spiral bar for sand cylinder internal layer circumference 1 to four/5th/
One, so it is easy to discharge.
Preferably, the sound-absorbing material layer material is polyester fiber, its sound-absorbing effect is preferable.
Preferably, being provided with filter mantle at the air inlet of the one-way exhaust valve, it can so prevent material with air-flow
It is discharged.
Compared with prior art, a kind of beneficial effect for preparing LiFePO4 ball mill of the utility model：By grinding
Mill tube internal layer inwall sets spiral bar and sets sound-absorbing material between its inside and outside two layers, can effectively increase the axial direction of material
Mobility, grinding batch mixing is caused to be more uniformly distributed and absorb noise in sand cylinder, while discharging material by one-way exhaust valve
The gas produced during grinding, can improve the security that equipment is used.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural representation for preparing LiFePO4 ball mill of the utility model.
Wherein, reference：1 is motor, and 2 be sand cylinder, and 3 be spiral bar, and 4 be sound-absorbing material layer, and 5 be unidirectional row
