Abstract

The utility model relates to a lithium cell negative pole powder material's agitating unit, axle including the stirred tank and in installing the stirring in the stirred tank, two helical mixing blade epaxially in the stirring are installed by the motor drive in the stirred tank outside to the axle in the stirring, epaxial still interval fixed mounting has nonrust rod iron in the stirring, two helical mixing blade pass through magnetic control mortise and tenon structure and stirring internal shaft connection. The utility model discloses epaxial nonrust rod iron get into smooth in will stirring earlier, because nonrust rod iron is little with the area of contact of material, its stir resistance force is little, can not take place the phenomenon of breaking, after material mixing was fluffy, the two helical mixing blade of operation can avoid the blade rupture again to clear up the material in the stirred tank when need not to have a power failure, sparingly the clearance process avoids the material of clearance to receive the production of pollution scheduling problem, improves product quality, reduction operating personnel's intensity of labour.

Description

A kind of agitating device of cathode of lithium battery powder body material

Technical field

This utility model relates to powder body mixing plant field, particularly to the mixing plant of lithium cell cathode material。

Background technology

Powder body material stirs it and utilizes under mechanical force and action of gravity, it is achieved material uniform stirring mixes。Current lithium cell cathode material mixing plant mainly adopts Double helix mixing plant, when the stirring theory of twin-shaft mixer is stirring on the interior axle of stirring under the effect of inside and outside ribbon, is stirred by material within the scope of cylinder。Interior ribbon is pushed material to both sides by centre, outer ribbon is pushed material to center by both sides, bleed back mixed material again under ribbon rotates, move along stirring internal axle axial, change thus defining convection circulation, stirring due to above-mentioned motion, material obtains quick Homogeneous phase mixing within very short time, and therefore it is that a kind of purposes is wide, adaptability, respond well high efficiency mixing apparatus。But when having a power failure suddenly during blender work, rapidly the material in blender must be put down, avoid long-time power failure to make the material in blender under self gravitation effect, settle, cause the degree of difficulty that cannot again be stirred and improve clear still, if be again stirred by force, it is susceptible to device damage situation, and product is polluted, affect product quality, and need after material blanking to lay especially and preserve, in order to avoid it is contaminated or the problem such as loss。

Utility model content

The applicant is for the disadvantages mentioned above of prior art, carry out studying and improving, the agitating device of a kind of cathode of lithium battery powder body material is provided, it can under long-time power-off condition, without by the clear still of material blanking in stirred tank, and can directly be again stirring for when a call comes, do not result in the situation such as mechanical breakdown, device damage。

In order to solve the problems referred to above, this utility model adopts following scheme:

A kind of agitating device of cathode of lithium battery powder body material, including stirred tank and be installed on axle in the stirring in stirred tank, in stirring, axle is driven by the motor outside stirred tank, in stirring, axle is provided with Double helix stirring vane, in described stirring, on axle, also interval is installed with stainless steel bar, described Double helix stirring vane is connected with axle in stirring by stirring outer shaft, stirs in outer shaft and stirring and is provided with magnetic control tenon structure between axle。

Of the present utility model have the technical effect that

Stainless steel bar on axle in stirring is first got into smooth by this utility model, owing to the contact area of stainless steel bar Yu material is little, its stirring resistance is little, breakage phenomenon will not occur, after material stirring is fluffy, rerun Double helix stirring vane, blade broken can be avoided, from without when having a power failure, the material stirred tank is cleared up, save scale removal process, the problems such as the material avoiding cleaning is contaminated produce, and improve product quality, reduce the labor intensity of operator；Producing magnetic additionally, due in stirring after axle energising, it is possible to material will be with magnetic impurity absorption on the rotating shaft, thus having possessed except magnetic effect, and then improving the performance of material。

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further。

As shown in Figure 1 to Figure 3, the agitating device of the cathode of lithium battery powder body material of the present embodiment, including stirred tank 1 and be installed in the stirring in stirred tank 1 axle 2, in stirring, axle 2 is driven by the motor 6 outside stirred tank 1, in stirring, axle 2 is provided with Double helix stirring vane 3, in stirring, on axle 2, also interval is installed with stainless steel bar 4, and Double helix stirring vane 3 is connected with axle 2 in stirring by stirring outer shaft 7, is provided with magnetic control tenon structure 5 between stirring outer shaft 7 and the interior axle 2 of stirring。

This utility model is after utilizing calutron (not shown) to be separated with axle 2 in stirring by the Double helix stirring vane 3 in stirred tank 1, the stainless steel bar 4 first passed through in stirring on axle 2 is by after fluffy for the material stirring in stirred tank 1, make axle 2 in stirring produce magnetic again through calutron to be fixed by Double helix stirring vane 3 by magnetic control tenon structure 5, and then make Double helix stirring vane 3 be stirred work, it is achieved normally stir。Stainless steel bar 4 on axle 2 in stirring is first got into smooth by this utility model, owing to stainless steel bar 4 is little with the contact area of material, its stirring resistance is little, breakage phenomenon will not occur, after material stirring is fluffy, rerun Double helix stirring vane 3, blade broken can be avoided, from without when having a power failure, the material stirred tank 1 is cleared up, save scale removal process, the problems such as the material avoiding cleaning is contaminated produce, and improve product quality, reduce the labor intensity of operator；Producing magnetic additionally, due in stirring after axle 2 energising, it is possible to material will be with magnetic impurity absorption on the rotating shaft, thus having possessed except magnetic effect, and then improving the performance of material。

Magnetic control tenon structure 5 in this utility model is conventional detachable attachment structure, belongs to prior art；Dotted line in Fig. 3 represents the mortise and tenon direction of motion。

Embodiment provided above is better embodiment of the present utility model, only it is used for this utility model is conveniently described, not this utility model is done any pro forma restriction, any art has usually intellectual, if in the scope without departing from the carried technical characteristic of this utility model, utilize the Equivalent embodiments that the done local of this utility model disclosed technology content is changed or modified, and without departing from technical characteristic content of the present utility model, all still fall within the scope of this utility model technical characteristic。
