Description

Technical Field

[0001] This utility model relates to a roller kiln, specifically a gas-fired flame-retardant sintering roller kiln for lithium battery materials. Background Technology

[0002] With the rapid development of new energy vehicles, lithium battery materials are also constantly innovating and developing. The technological advancements in lithium battery materials place increasingly higher demands on sintering equipment (including temperature difference, particle density, oxygen-enriched atmosphere, inert gas protection, and harmful substance control). Currently, the inner chambers of roller kilns used for sintering in lithium battery material companies are generally constructed with axe-shaped bricks, with arches exceeding 400mm in height. This negatively impacts the regulation of furnace pressure and atmosphere, especially in kilns where the materials being sintered require an oxygen-enriched environment to meet process requirements (reducing atmospheres are detrimental to material sintering). Utility Model Content

[0003] Purpose of the invention: The purpose of this utility model is to overcome the shortcomings of the prior art and provide a gas-fired flame-insulated sintering lithium battery material flat beam and flat top energy-saving roller kiln with convenient adjustment of kiln internal temperature, pressure and atmosphere, and significant energy-saving effect.

[0004] Technical Solution: To solve the above-mentioned technical problems, the present invention provides a gas-fired flame-retardant sintering lithium battery material flat-beam flat-top energy-saving roller kiln, which includes a kiln body, a flat-top structure on the top of the kiln body, and a flat beam structure inside the kiln body. The flat-top structure includes several ceiling bricks that are closely connected and flush at their lower ends. The flat beam structure includes an upper heat-conducting load-bearing straight beam and a lower heat-conducting plate support beam. An upper heat-conducting plate is provided on the upper heat-conducting load-bearing straight beam, and a lower heat-conducting plate is provided on the lower heat-conducting plate support beam. An upper combustion chamber is located above the upper heat-conducting plate, and a lower combustion chamber is located below the lower heat-conducting plate. A guide mechanism is provided above the lower heat-conducting plate, and several saggers are provided above the guide mechanism.

[0005] Furthermore, six rows of double-layered saggers are provided above the guide mechanism.

[0006] Furthermore, the upper heat-conducting load-bearing straight beam and the lower heat-conducting plate support beam are arranged in parallel.

[0007] Furthermore, the upper end of the ceiling brick is suspended from the top of the kiln body via hooks.

[0008] Furthermore, the guiding mechanism includes a plurality of guide rollers, on which a guide belt is provided.

[0009] Furthermore, the ceiling tiles are made of high-temperature resistant, low-expansion, and corrosion-resistant materials.

[0010] Beneficial effects: Compared with the prior art, the significant advantages of this utility model are: This utility model uses ceiling bricks made of high temperature resistant, low expansion and corrosion resistant materials to build on the top layer of the furnace, forming a flat top structure, which changes the previous arched structure, making it more convenient to adjust the temperature, pressure and atmosphere of the inner furnace, and achieving significant energy-saving effect. The furnace is in an oxygen-rich state, which is conducive to the sintering of materials. The parallel upper heat-conducting load-bearing straight beam and lower heat-conducting plate support beam form a flat beam structure. In addition, there are six rows of double-layer saggers above the guide mechanism, which are convenient to operate and meet the actual use requirements. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, the present invention discloses a gas-fired flame-retardant sintering lithium battery material flat-beam flat-top energy-saving roller kiln, comprising a kiln body 1, a flat-top structure on the top of the kiln body 1, and a flat beam structure inside the kiln body 1. The flat-top structure includes several ceiling bricks 2, which are closely connected and flush at their lower ends. The upper ends of the ceiling bricks 2 are suspended from the top of the kiln body 1 by hooks. The ceiling bricks 2 are made of high-temperature resistant, low-expansion, and corrosion-resistant materials. The flat beam structure includes an upper heat-conducting load-bearing straight beam 3 and a lower heat-conducting plate support beam 4, which are arranged in parallel. An upper heat-conducting plate is provided on the upper heat-conducting load-bearing straight beam 3, and a lower heat-conducting plate is provided on the lower heat-conducting plate support beam 4. An upper combustion chamber 5 is located above the upper heat-conducting plate, and a lower combustion chamber 6 is located below the lower heat-conducting plate. A guiding mechanism is provided above the lower heat-conducting plate, and the guiding mechanism includes several guide rollers with guide belts on the guide rollers. Six rows of double-layer saggers 7 are provided above the guiding mechanism.

[0014] This utility model uses ceiling bricks made of high-temperature resistant, low-expansion, and corrosion-resistant materials to be laid on the top layer of the furnace to form a flat-top structure, which changes the previous arched structure. This makes it easier to adjust the temperature, pressure, and atmosphere of the inner furnace, resulting in significant energy savings. The furnace is in an oxygen-rich state, which facilitates material sintering. It adopts parallel upper heat-conducting load-bearing straight beams and lower heat-conducting plate support beams to form a flat beam structure. In addition, there are six rows of double-layer saggers above the guide mechanism, which are convenient to operate and meet the actual use requirements.
