Space is the accommodating chamber for holding LiMn2O4 gel, is provided with the container that can hold liquid on the upside of the accommodating chamber, the heat supply room to
Accommodating chamber transmits heat and LiMn2O4 gel is dried and is calcined, and the waste heat after drying and roasting in receiving is to the container
Heated.
Preferably, the heat-conducting plate is formed using the upper, middle and lower segment folded plate for forming two bendings, wherein upper folded plate
Rolled tiltedly to accommodating chamber with lower flap portion, middle folded plate rolls oblique to heat supply room.
Preferably, being horizontally disposed with the accommodating chamber positioned at the bending part of the middle folded plate and lower flap portion has and can place
The dividing plate of LiMn2O4 gel.
Preferably, the thermal hole for connecting the heat supply room and accommodating chamber is offered on the lower flap portion.
Preferably, placing plate positioned at horizontal be provided with of the bending part of middle folded plate and lower flap portion in the heat supply room, this is put
Put plate and be provided with thermal source.
Preferably, offer several through holes on the placement plate.
Preferably, the container bottom is provided with valve, opening valve can make the material in container flow into the accommodating chamber.
As can be known from the above technical solutions, the present invention realizes holding, dry and being calcined for gel by a firing chamber, if
Count ingenious, simple in construction and cost-saved；The container on the upside of accommodating chamber is heated using waste heat simultaneously, realizes system
Standby gel can not only save the energy, and substantially increase operating efficiency to the full process stream journey of roasting.
Brief description of the drawings
Fig. 1 is the structural representation of the preferred embodiment of the present invention.
Embodiment
The present invention is discussed in detail with reference to Fig. 1, illustrative examples of the invention and explanation are used for explaining this herein
Invention, but it is not as a limitation of the invention.
The preparation facilities of lithium manganate cell positive electrode material, including firing chamber 1, the firing chamber are separated into left and right by heat-conducting plate 2
Two spaces, one of space are heat supply room 11, and another space is the accommodating chamber 12 for holding LiMn2O4 gel, the heat supply room
Heat is transmitted to accommodating chamber LiMn2O4 gel is dried and is calcined, it can be seen that, the present invention is just real using a firing chamber
Holding, dry and being calcined for LiMn2O4 gel is showed, its is simple in construction, cost is relatively low.Meanwhile by the preheating of accommodating chamber to holding
Device 4 is heated, and not only makes full use of waste heat, saves the energy, and maximizing realizes consecutive production.
Preferably, the heat-conducting plate 2 is formed using the upper, middle and lower segment folded plate for forming two bendings, wherein upper folded plate
21 and lower flap portion 23 rolled to accommodating chamber oblique, middle folded plate 22 rolls oblique to heat supply room.The lower flap portion so set make it that its is right
The heat supply room answered forms the conical region that lower end is small, upper end is big, is advantageous to heat importing accommodating chamber；The middle folding so set
Plate causes its corresponding accommodating chamber to form the conical region that lower end is small, upper end is big, is advantageous to hold gel, at the same it is inclined in
Folded plate, facilitate heat supply room to heat, heating effect can be improved；The upper folded plate so set is advantageous to the gas discharge of heat supply room,
The steam for being advantageously used for accommodating chamber is collected and outer row.
The present invention is horizontally disposed with to have in the accommodating chamber positioned at the bending part of the middle folded plate and lower flap portion can place manganese
The dividing plate 13 of sour lithium gel, so that forming space at the lower flap portion of accommodating chamber, be advantageous to take out gel；And on the lower flap portion
The thermal hole 24 for connecting the heat supply room and accommodating chamber is offered, so as to which the hot gas in heat supply room is imported into space, to gel bottom
Heat in portion；The present invention places plate 14 also in the heat supply room positioned at horizontal be provided with of the bending part of middle folded plate and lower flap portion, and this is put
Put plate and be provided with thermal source 3, so that space is also form at the lower flap portion of heat supply room, it is empty on the one hand can to provide enough burnings
Gas, ensure that thermal source fully burns；On the other hand waste residue after convenient discharge thermal source burning etc..In implementation process, thermal source can be adopted
Take coal, carbon, electricity etc., at the same can by middle folded plate providing holes to gel roasting direct, can also be not provided with hole and pass through heat conduction
Middle folded plate is to the indirect roasting of gel, and its is ingenious in design, using flexible.
From the foregoing, it will be observed that the present invention is obliquely installed by the above-mentioned of middle folded plate, can be by the heat in heat supply room largely
Concentrate at middle folded plate, realize the heating to gel-side, ensure that heating effect, improve the uniformity of heating；Meanwhile
Place and offer several through holes 15 on plate, so as to which the heat in heat supply room to be passed sequentially through to lower space, the lower flap portion of heat supply room
Thermal hole and the lower space of accommodating chamber add to gel bottom-heated, while the side and bottom that not only realize gel
Heat, not only heating effect is good, and heats more uniform.
Container is arranged on the upside of accommodating chamber by the present invention, and container is added using steam caused by gel roasting process
Heat, steam-heated temperature are easier to control, and temperature will not be too high, are adapted to the heating for preparing gel solution.Ying Rong simultaneously
Indoor side wall of receiving sets steam hole, makes to arrange outside steam, prevents that receiving room pressure is too high and security incident occurs.In implementation process
In, can be in the valve 41 that container bottom setting automatically controls, opening valve makes the material in container flow into the accommodating chamber, container
The solution for preparing gel is held, solution is formed gel by heating container, gel is directly entered accommodating chamber opening valve
It is calcined, it is achieved thereby that automation and continuous production, substantially increase production efficiency.
Above-mentioned embodiment is used for illustrative purposes only, and is not limitation of the present invention, relevant technical field
Those of ordinary skill, can be so that various changes can be made and modification without departing from the spirit and scope of the present invention, therefore institute
There is equivalent technical scheme also to belong to scope of the invention.
