The utility model patent with publication number CN102745671A discloses a pot-type carbon calciner, belonging to a calciner for carbon production. The pot-type carbon calciner is characterized in that every four calcining pots and furnace walls with heating flame paths positioned on two sides of a pot body form a combustion chamber, expansion joints and a collecting flue are arranged among the combustion chambers, the furnace walls with the heating flame paths are provided with 8-10 layers of flame paths, the flame paths are communicated with a preheating air path, the calcining pot body is connected with a discharging pot, an interlayer cooling water jacket is arranged on the periphery of the discharging pot, the whole calciner consists of 72 calcining pots of 18 combustion chambers arranged in a straight line, a furnace protecting large knife rest is arranged on the outer side of a front wall of the calciner, a furnace protecting frame is arranged on the outer side of a rear wall, the bottom of the combustion chamber is supported by a furnace bottom support, the top of the calcining pot body is provided with a charging opening, the bottom of the calcining pot body is connected with a discharging pot, the interlayer cooling water jacket is arranged on the outer side of the discharging pot, a discharging machine is arranged at the lower end of the discharging pot, and a small storage bin is arranged between the discharging machine and the discharging valve. Realizes the bidirectional utilization of volatile matters, realizes full-automatic closed continuous discharge, and has good economic benefit and environmental benefit.

In the prior art, indirect heating is generally adopted outside a tank body, and volatile matters are completely introduced into a flame path from an opening at the upper part of the tank body for combustion after being heated. The drawbacks of this structure are: 1. the resistance of the material layer is too large, particularly materials in the center of the tank can be heated to the temperature at which volatile components are completely released only when reaching the height position of 6 layers of flame paths or even below, and then the separated volatile components can enter an outlet at the top of the tank only when overcoming the material resistance at the height position of 6 layers of flame paths, so that the volatile components are difficult to discharge, and the calcining quality and the calcining capacity are influenced; 2. in the process of upward passing through the material layer, the volatile matters difficult to release are repeatedly condensed after encountering cold materials, so that the heat transfer burden is increased, and the phenomena of material coking, material bridging and the like are caused, so that potential safety hazards are caused; 3. the material hinders and leads to the malleation too big in the jar, and the updraft is obstructed, and partial volatiles flows down, and at water jacket, row of material machine, the jigging conveyer position below 7, 8 layers flame path height, meet the air emergence blasting phenomenon that leaks into to influence safety in production.

Obviously, the tank body structure and the exhaust method of the existing tank furnace are not ideal.

SUMMERY OF THE UTILITY MODEL

The lower cushion brick and the exhaust duct brick are built from bottom to top to form a wall body which is respectively embedded into two ends of the inner part of the middle upper section of the tank body and clamped by the staggered platforms in the tank.

The tank body main body is of a traditional rectangular tank body structure and is formed by combining a plurality of special-shaped bricks with mortises; in the areas where the arc-shaped bricks are located at two ends of the middle upper part of the tank body, a slab staggering space is reserved on the inner side, and the slab staggering depth is 5-15 mm; the two ends of the bottom of the tank body are of thick solid structures and are used as supports for the embedded bricks on the middle upper part.

As a further preferred scheme, the lower cushion brick is a rectangular solid brick (with two-corner arc transition) masonry and is embedded into staggered platforms at two ends of the middle section in the tank body; the bricks are used as the transition of the silica brick tank body, and are built upwards from a solid support platform of a clay brick section at the lower part of the tank body, the height of the bricks is about 1000-2000 mm, and the bricks are roughly positioned at the height positions of the flame paths from the 7 th layer to the 8 th layer.

As a further preferred scheme, the contour of the exhaust duct brick is consistent with that of the lower cushion brick, and the exhaust duct brick is laid right above the lower cushion brick(ii) a The center of the exhaust passage brick is provided with a long round through hole with the specification of (200-300 mm) x (30-80 mm), and the internal flow cross section of the exhaust passage brick is about 0.01-0.02 m²After combined building, an exhaust channel is formed to reach the tank top; a flat channel is reserved on the top (or bottom) surface of each exhaust channel brick, each seam is 200-360 mm long, 5-30 mm high and 50-100 mm apart, and the flat channel is an airflow collecting channel for materials at the height of each layer of brick.

When the device normally operates, the materials in the tank are heated to separate out combustible volatile matters, and part of airflow upwards passes through the materials to reach the top of the tank; the rest airflow passes through the airflow collecting flat channels of each layer and transversely reaches the exhaust channels at the two ends of the tank body and then reaches the top of the tank. Therefore, even if the volatile components are at the flame path height of the 6 th layer (even the 8 th layer), the volatile components can still be easily discharged upwards through the exhaust channel, and the materials in the tank cannot enter the exhaust channel.

Compared with the prior art, the structure has the advantages of simple construction, lower implementation cost, high efficiency, quick volatile component discharge, stable service performance, long service life, guaranteed product quality and capacity, high heat energy utilization rate and low operation and maintenance cost.
