The semi-coke three-cylinder dryer comprises a composite cylinder, a transmission device, a feeding device, a discharge device and a preheating cylinder, wherein the preheating cylinder is arranged in an inner cylinder through a bracket rod; the front end of the preheating cylinder is provided with an opening; a choke plate is arranged in the rear end of the preheating cylinder and is provided with at least one ventilation hole; the front end of the preheating cylinder is positioned in the front end of the composite cylinder; an upper pipe of a feed pipe of the feeding device is provided with an upper ventilation hole; an upper air inlet pipe is arranged on the upper ventilation hole and is positioned on the outer side of the upper pipe; a lower pipe of the feed pipe of the feeding device is provided with a lower ventilation hole; a lower air inlet pipe is arranged on the lower ventilation hole and is positioned on the outer side of the lower pipe; a stopping plate is arranged on the lower ventilation hole, is positioned in the lower pipe and stops a material from entering the lower ventilation hole; a left guide plate is arranged on the left side of the inner surface of a lower cone of the discharge device; a right guide plate is arranged on the right side of the inner surface of the lower cone of the discharge device.

Description

technical field [0001] The invention relates to a dryer, in particular to a blue carbon three-cylinder dryer. Background technique [0002] An existing blue carbon three-cylinder dryer includes a composite cylinder body, a transmission device, a feeding device and a discharging device. The composite cylinder contains three outer cylinders, middle cylinders and inner cylinders with different diameters from large to small. The middle cylinder is located in the outer cylinder, the inner cylinder is located in the middle cylinder, the outer cylinder, the middle cylinder The body and the inner cylinder are coaxial, and the inner walls of the outer cylinder, the middle cylinder and the inner cylinder are equipped with spiral lifting plates, and the composite cylinder is placed on the transmission device. The feeding device and the discharging device are respectively located at the front end and the rear end of the compound cylinder. The feeding device is composed of a feed pipe ...

AI Technical Summary

Problems solved by technology

When the above-mentioned dryer dries the blue carbon, because the blue carbon in the feeding pipe of the feeding device does not exchange heat with the high-temperature hot air, the drying efficiency of the blue carbon three-cylinder dryer is affected; After the carbon is lifted by the spiral lifting plate in the inner cylinder, in the process of falling, due to the large drop, the breakage rate of the blue carbon is relatively high, thus greatly reducing the economic value of the blue carbon; After the discharge port enters the discharge device, it falls directly into the discharge cone. Due to the large drop, it is easy to cause the blue carbon to break
