Description of the drawings

Fig. 1 is the structural schematic diagram of the preferred embodiment of the utility model.

Specific implementation mode

The utility model is discussed in detail with reference to Fig. 1, this utility model illustrative examples and illustrate to use It explains the utility model, but is not intended to limit the scope of the present invention.

The production equipment of the lithium manganate battery material of the utility model, including firing chamber 1, firing chamber upside are connected with Sheng The container 6 of solution is put, such as can be the solution for preparing LiMn2O4 gel, Gas grinding machine 5 is connected on the downside of container, it is fired Room roasting after powder conveying to the Gas grinding machine be ground, then under the airflow function of the grinder by grinding after Powder conveying roasts again to firing chamber.The utility model, can be automatically real by the slitless connection of firing chamber and Gas grinding machine The process for now roasting, grinding, roasting again, substantially increases production efficiency.Meanwhile container is added by the preheating of firing chamber Heat not only makes full use of waste heat, energy saving, and maximizing realizes consecutive production.

Specifically, the firing chamber 1 of the utility model is separated into left and right two spaces, one of space by heat-conducting plate 2 For for hot cell 11, another space is the accommodating chamber 12 for holding LiMn2O4 gel, this transmits heat to manganese for hot cell to accommodating chamber Sour lithium gel is dried and roasts, it can be seen that, the utility model is achieved that LiMn2O4 gel using a firing chamber It holds, dry and roasts, it is simple in structure, cost is relatively low；The heat-conducting plate 2 is using the upper, middle and lower segment for forming two bendings Folded plate is constituted, wherein upper folded plate 21 and lower flap portion 23 roll tiltedly to accommodating chamber, middle folded plate 22 is oblique to being rolled for hot cell.It sets in this way The lower flap portion set its corresponding to form the conical region that lower end is small, upper end is big for hot cell, is conducive to import heat and hold Receive room；The middle folded plate being arranged in this way makes its corresponding accommodating chamber form the conical region that lower end is small, upper end is big, is conducive to contain Gel, while inclined middle folded plate are put, facilitates and is heated for hot cell, heating effect can be improved；The upper folded plate being arranged in this way is conducive to For the gas discharge in hot cell, the steam for being also advantageously used for accommodating chamber is collected and outer row.

The utility model, which is horizontally disposed in the accommodating chamber positioned at the bending part of the middle folded plate and lower flap portion, to be had and can put The partition board 13 of LiMn2O4 gel is set, and the partition board is flexibly connected with the heat-conducting plate, so as to which the powder after roasting is poured into appearance It receives and is formed in gap at the lower flap portion of room, be conducive to take out gel；The accommodating chamber bottom is equipped with discharge hole 16, the powder in gap Body can be flowed out by the discharge hole, facilitate collection.In implementation process, described partition board one end is hinged with heat-conducting plate, and the other end is logical It crosses the movable support rod 4 being arranged on lower flap portion to support, which is made of upper boom 41 and lower beam 42, lower beam lower end and lower folding Plate is hinged, and lower beam upper end is hinged with upper boom lower end, and upper boom upper end is hinged with the other end described in partition board, under lower beam upper end and upper boom It holds hinged place to be equipped with push-pull rod 43, by pulling downward on push-pull rod, upper boom supporting clapboard can be made, ensure that partition board is horizontal, facilitate Sheng Put gel；After the completion of roasting, by pushing up push-pull rod, the partition board other end can be made to tilt down, thus the powder after roasting Body pours into the lower space of accommodating chamber, then is ground powder conveying to Gas grinding machine by discharge hole, after grinding Powder is delivered to firing chamber's regrinding under the action of air-flow.

It is offered on the lower flap portion of the utility model and is connected to the thermal hole 24 for hot cell and accommodating chamber, thus by heat supply Indoor hot gas imports gap, to gel bottom-heated；The utility model is located at middle folded plate and lower folding also in the heat supply room The bending part level of plate is equipped with placement plate 14, which is equipped with heat source 3, so that for also being formed at the lower flap portion in hot cell On the one hand gap can provide enough burning air, ensure that heat source fully burns；On the other hand after facilitating discharge heat source burning Waste residue etc..In implementation process, heat source can take coal, carbon, electricity etc., at the same can by middle folded plate providing holes it is straight to gel Roasting is connect, hole can be also not provided with and gel is roasted indirectly by the middle folded plate of heat conduction, it is ingenious in design, using flexible.

From the foregoing, it will be observed that the utility model is obliquely installed by the above-mentioned of middle folded plate, it can be by the larger journey of the indoor heat of heat supply It concentrates at middle folded plate to degree, realizes the heating to gel-side, ensure that heating effect, improve the uniformity of heating； Meanwhile several through-holes 15 are offered in placement plate, to by the indoor heat of heat supply pass sequentially through the lower space for hot cell, under The thermal hole of folded plate and the lower space of accommodating chamber are to gel bottom-heated, while not only realizing the side and bottom of gel Heating, not only heating effect is good, but also heats more uniform.

In implementation process, container should be arranged on the upside of accommodating chamber the utility model, the steam generated using gel Container is heated, steam-heated temperature is relatively easy to control, and temperature will not be excessively high, is suitble to prepare adding for gel solution Heat.Should steam hole be set side wall in the accommodation room simultaneously, make to arrange outside steam, prevent receiving room pressure excessively high and safe thing occurs Therefore.

The above embodiment is only for illustration of the utility model, and is not limitations of the present invention, related skill The those of ordinary skill in art field can be with various changes can be made in the case where not departing from the spirit and scope of the utility model And modification, therefore all equivalent technical solutions should also belong to the scope of the utility model.
