Embodiment Construction

[0033] see figure 1 As shown, the rotary retort includes a rotary cylinder 5, a screw feeder 1 arranged at the tail of the rotary cylinder 5, and a discharge screw mechanism 10 arranged at the head of the rotary cylinder 5 to drive the rotary cylinder 5 The rotating power unit 7 and the support unit 8 supporting the rotating cylinder 5 . A tail sealing device 2 is provided between the screw feeder 1 and the rotary cylinder 5 , and a head sealing device 9 is provided between the discharge screw mechanism 10 and the rotary cylinder 5 . The support device 8 can be a support device with retaining wheels, or a support device without retaining wheels.

[0034] see Figure 7 , Figure 8 , the inside of the rotary cylinder 5 is provided with a rotary cylinder shaft 6, and the rotary cylinder 5 is welded between the rotary cylinder shaft 6 and the inner circumferential side wall of the rotary cylinder 5 to divide the interior of the rotary cylinder 5 into a plurality of compartment...

Abstract

A dual-cone spiral forced feeding device is composed of an inner cone, an outer cone and at least three spiral blades, wherein spiral blades which are evenly distributed are welded between the inner cone and the outer cone, and a charging end face of the inner cone is located between a charging end face of the outer cone and a discharging end of the outer cone. By the aid of the dual-cone spiral forced feeding device, materials and solid heat carriers can be delivered compulsively, so that materials and solid heat carriers can enter and exit from the charging and discharging spiral space quickly without blocking returning, spiral blades in the dual-cone spiral forced feeding device can rotate along with a rotating cylinder body, and the produced driving force can effectively improve accumulation and blocking returning phenomena which occur during charging and discharging of rotating type dry distillation machines.

Description

technical field [0001] The invention relates to a feeding device installed in a rotary cylinder of a rotary carbonization furnace. Background technique [0002] At present, with the promulgation of the "12th Five-Year Plan for the Coal Industry", the state requires that in the next few years, we will vigorously develop clean coal technology and strengthen the research and development and demonstration of lignite upgrading technology. Lignite low-temperature pyrolysis technology has attracted increasing attention in China because of its high yield of tar and gas, and solid high-carbon semi-coke, and corresponding experiments and promotions have been carried out in major lignite producing areas such as Inner Mongolia and Northeast China. [0003] The rotary retort furnace is mainly used for calcining cement clinker in the cement industry, also for calcining granular and powdery materials in the refractory and ceramic industries, and also for drying various raw materials in the...
