Description

Honeycomb sintering dish

Technical Field

The invention belongs to the field of sintering of lithium battery anode materials, and particularly relates to a honeycomb sintering disc.

Background

In the sintering process of the lithium battery anode material, the anode material is required to be filled into a special material container and then pushed into a sintering furnace for sintering, but the sintering quality of the anode material is easily influenced by some problems of the existing material container, and on one hand, the material container with the existing structure cannot enable the anode material to be sufficiently contacted with the atmosphere in the sintering furnace, so that the sintered product has low quality or uneven performance; on the other hand, the material containers are large in quantity, the material distribution is uneven, the production process is troublesome to operate, and the sintering degree of the anode materials in one batch of material containers can not be consistent.

Disclosure of Invention

In view of the above problems, the present invention aims to provide a honeycomb sintering tray, which aims to solve the technical problems of low sintering efficiency and non-uniform sintering degree of the conventional lithium battery positive electrode material.

The utility model provides a honeycomb sintering dish, includes stainless steel base and crucible tray, the crucible tray is fixed through twisting the staple on the stainless steel base, the crucible tray top sinks to form the inner chamber of radius frustum type, the honeycomb dish that the shape matches has been placed to the intracavity of crucible tray, the honeycomb dish comprises the honeycomb holes of a plurality of inseparable adjacent ranges, install the connection mounting in the honeycomb hole at honeycomb tray center, be fixed with a vertical pull rod on the connection mounting, be provided with the pull ring on the pull rod.

Furthermore, the bottom of the stainless steel base is provided with a support leg.

Furthermore, a handle is arranged on the outer side wall of the crucible tray.

The invention has the beneficial effects that: the utility model provides a honeycomb sintering dish, including stainless steel base and crucible tray, the inner chamber of formation radius bench type is sunk at crucible tray top, the honeycomb dish that shape and crucible tray inner chamber match is placed to the inner chamber at crucible tray, will treat the positive pole material of sintering before the sintering and pour into the honeycomb dish, then floating, put into the fritting furnace with whole sintering dish and sinter, the honeycomb type structure is firm, it is easy even to be heated, atmosphere and the area of contact of positive pole material have been increased, the sintering efficiency of positive pole material is improved, honeycomb tray center is through connecting a fixed pull rod of mounting, set up the pull ring on the pull rod and conveniently carry out the honeycomb dish after the sintering, oblique crucible tray after the sintering, the sintering product is easily poured out to crucible tray inner chamber lateral wall certain slope.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, a honeycomb sintering tray comprises a stainless steel base 1 and a crucible tray 2, wherein the crucible tray 2 is fixed on the stainless steel base 1 by screwing a fixing nail 3, the top of the crucible tray 2 sinks to form an inner cavity 4 in an inverted circular truncated cone shape, a honeycomb tray 5 with a matched shape is placed in the inner cavity of the crucible tray 2, the honeycomb tray 5 is composed of a plurality of honeycomb holes which are closely and adjacently arranged, a connecting and fixing part 6 is installed in the honeycomb hole in the center of the honeycomb tray 5, a vertical pull rod 7 is fixed on the connecting and fixing part 6, and a pull ring 8 is arranged on the pull rod 7.

Placing a honeycomb disc in a crucible disc, pouring an anode material to be sintered into the honeycomb disc before sintering, and then leveling, so that the quality of the anode material to be sintered contained in each honeycomb cell hole is equal, placing the whole honeycomb sintering disc into a sintering furnace for sintering, wherein the honeycomb structure is an optimal topological structure covering a two-dimensional plane, the cell holes are regular hexagons and are stable compared with other shapes, the contact area between atmosphere and the anode material is increased, the honeycomb disc is easy to be uniformly heated, the sintering quality and efficiency of the anode material are improved, the center of the honeycomb disc is fixedly provided with a pull rod through a connecting fixing piece, the pull rod is provided with a pull ring, after sintering is finished, the honeycomb disc is lifted out through the pull ring, when the crucible disc is inclined, the side wall of the inner cavity of the crucible disc forms a certain slope to easily pour out a sintered product, and after the sintered product is collected, the honeycomb disc is placed next, the next charging and sintering operation can be carried out, if the crucible tray or the stainless steel base is worn after being used for a certain period, the fixing nail can be screwed out of the stainless steel base for replacement, and the equipment cost is obviously saved.

As a preferable structure of the honeycomb sintering tray, as shown in fig. 1, the bottom of the stainless steel base 1 is provided with support legs 9, which is convenient for a production worker to take out the honeycomb crucible tray. The outer side wall of the crucible tray 2 is provided with a handle 10, so that the operation of dumping the sintering finished product by production workers is facilitated.

Whole crucible dish simple structure, treat the positive electrode material's of sintering volume easy control, and can once sinter the downthehole positive electrode material of a plurality of honeycomb cells, still can enlarge or reduce the diameter in the honeycomb cell of honeycomb dish as required, satisfy other sintering material's different structure, with the diversified demand of the different area of contact of atmosphere, still can be according to the production demand even, the honeycomb crucible dish that design same proportion has more honeycomb cells, it is disposable to sinter more positive electrode material, it carries out repeated material loading to reduce to need tens sintering gate alms bowl of logarithm many times among the prior art, sintering, take out, the operation of pouring, and the production efficiency is improved, for the production workman provides the facility in the operation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
