The industrial automation production equipment mainly comprises a belt deironing conveyor, a belt conveyor, a coarse grinding machine, a classifying screen, a hoisting machine, main equipment 1-3-stage fine drying machine, a wet-type separating and aggregating device and a dust-removing purifying chamber, wherein a fine lignite dry powder storage silo and a moulding machine are successively arranged and connected in a technological process; and the lignite is converted into briquette, wherein the original all water of lignite is reduced to less than 10wt% from less than 65wt% by virtue of the 1-3-stage fine drying machine, hydrophilicity which is smooth outside and coarse inside and is compact outside and loose inside is changed into hydrophobicity, and surface property is converted into the property similar to excellent bituminite. The equipment provided by the invention has unique and novel structure, high drying efficiency and low cost; a product is difficult to absorb water, spontaneous combustion and heat value are greatly improved, and the problems of weathering, spontaneous combustion, transportation, storage, great investment and high cost are comprehensively solved. The equipment and method provided by the invention can be widely applied to lignite dehydration moulding in power plants at home and aboard and other boilers, and the equipment provided by the invention is dehydration drying and quality improving technical equipment of a new generation.

The invention provides a fireproof household wiring harness. The fireproof household wiring harness comprises a wiring fixing device and a plurality of cables which penetrate through the wiring fixingdevice and are elastically connected with the wiring fixing device, the wiring fixing devices are arranged at intervals along the length direction of the plurality of cables, and the wiring fixing devices are insulators; wherein each cable is provided with a first elastic piece of which one end is connected with the adjacent cable, and the first elastic piece is an insulator; the wiring fixing device comprises a buffer layer in sliding connection with a plurality of cables, a connecting piece is fixed on the buffer layer, and the connecting piece is in sliding connection with the buffer layer. The connecting piece is an elastic connecting piece; a sliding groove is formed in the surface, close to the cable, of the buffer layer in a sunken mode, and the end, away from the cable, of the connecting piece is slidably connected into the sliding groove. The technical problem that when one electric wire is on fire, the other electric wire close to the electric wire is ignited, so that the whole cable bundle is further ignited, and the whole cable bundle is ignited is solved.
