Description

Technical Field

[0001] The utility model relates to the technical field of kilns, in particular to a carbon kiln. Background Art

[0002] Kiln is a kind of equipment made of refractory materials for calcining materials or firing products. At present, the roasting furnaces used by carbon production enterprises are mainly: covered ring roasting furnace; open ring roasting furnace; car bottom roasting furnace, etc.

[0003] The kiln needs good heat preservation and exhaust gas treatment after opening the cover. However, the exhaust gas of the general closed kiln will be directly released into the air after opening the cover, which will affect the surrounding air. Long-term absorption will cause great harm to the body. In addition, the kiln built with refractory bricks has poor heat preservation and heat dissipation, which increases costs and resources and is inconvenient to use. For this reason, we have re-provided a carbon kiln. Utility Model Content

[0004] The utility model aims to provide a carbon kiln to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a carbon kiln, comprising a kiln body, wherein four groups of new refractory bricks are arranged equidistantly inside the kiln body, and the inner wall of the kiln body is provided with new high-temperature refractory wool.

[0006] Preferably, a plurality of groups of burners are equidistantly arranged on both sides of the outer wall of the kiln body for heating the kiln.

[0007] Preferably, heat transfer tubes are provided between the multiple groups of burners for heat conduction and waste heat recovery.

[0008] Preferably, a hollow groove is opened in the middle of the novel refractory brick, and an outer brick body and an inner brick body are formed.

[0009] Preferably, the surface of the outer layer brick body is coated with a high temperature heat insulating material, and the inner surface of the inner layer brick body is coated with a high temperature refractory material.

[0010] Preferably, a thermal insulation material layer is provided between the outer brick body and the inner brick body.

[0011] Preferably, the novel high-temperature refractory wool is formed by stacking a plurality of refractory wool blocks and reinforcement columns.

[0012] The utility model provides a carbon kiln having the following beneficial effects:

[0013] (1) The utility model heats by means of a burner and conducts heat by means of a heat conduction tube. It is assembled with new refractory bricks and new high-temperature refractory wool, which improves the carbonization effect, saves energy and reduces emissions, recovers waste heat, optimizes combustion, and has a multi-group design that enables automatic control, real-time monitoring and adjustment.

[0014] (2) The utility model provides a hollow groove in the middle of the new refractory brick, thereby reducing the contact area between the refractory brick and the ceramsite kiln body, reducing heat loss, and ensuring the structural strength of the refractory brick. At the same time, the upper surface structure of the refractory brick will not be damaged, so that the refractory brick can continue to withstand the friction and impact caused by the ceramsite.
