Problems solved by technology
[0006] 1. When the hopper is full, there will be material leakage, resulting in incomplete discharge;
[0007] 2. The track and the material plate are installed in parallel. When the material layer is too wide, the track span is too large, and there is no load-bearing shaft in the middle of the track, which will lead to the phenomenon of "bridge collapse" in the middle of the track, resulting in the scraping of the hopper and the furnace. Scratches on the floor

Embodiment Construction
[0026] The coal pyrolysis rotating bed discharging device of the present invention will be further described in detail below in conjunction with the accompanying drawings:
[0027] The invention provides a coal pyrolysis rotary bed discharge device, which includes a frequency conversion motor, a driving shaft, one or more driven shafts, a crawler connected between the driving shaft and the driven shaft, and a scraper connected to the crawler. plate. There are gears on the driving shaft and the driven shaft, which are engaged with the crawler. The driving shaft drives the crawler to rotate, and the driven shaft plays the role of hoisting and supporting, and rotates synchronously with the crawler. The driving shaft and the driven shaft are hollow shafts, the inside of which is a cooling water chamber, and the two ends or one end of the cooling water chamber are respectively provided with a water inlet pipe and a water outlet pipe, and the cooling water chamber is connected with ...

Abstract
The invention relates to the field of coal pyrolysis to produce semi-coke, and provides a coal pyrolysis rotary bed discharge device, which includes a driving shaft and one or more driven shafts, and crawler belts are used between the driving shaft and the driven shafts. Connected, the outer side of the track is provided with a plurality of evenly distributed scrapers. The coal pyrolysis rotary bed discharge device provided by the present invention realizes continuous discharge of pyrolysis semi-coke in small batches and large spans, avoids crushing caused by material tumbling and pushing, has high scraping efficiency, good continuity, and great The crushing rate of the material in the discharging process is reduced.
Description
technical field [0001] The invention relates to the field of producing semi-coke by coal pyrolysis, and provides a coal pyrolysis rotary bed discharge device. Background technique [0002] Coal pyrolysis semi-coke technology is widely used in iron and steel metallurgy, non-ferrous metallurgy, calcium carbide production, chemical industry and other fields. All fields have requirements for semi-coke particle size, and the particle size of semi-coke should not be too small. The existing coal pyrolysis coke ovens are mainly vertical furnaces and horizontal furnaces. The existing furnace types have strict raw material requirements, uneven heating of the material layer in the high and long directions, high energy consumption, and small processing capacity for a single unit. defect. Patent application No. 200910238038.1 and patent application No. 201120253428.9 relate to a rotary bed device for pyrolyzing coal. Pyrolysis produces semi-coke products, which have the advantages of wi...
