Embodiment
[0023] A new type of scrap steel feeding vibration conveying device, such as figure 1 As shown, it includes a vibration source 1, an upper conveying trough 2 and a lower conveying trough 3, the bottom of the upper conveying trough 2 is fixedly connected to the top of the lower conveying trough 3, and the length of the lower conveying trough 3 is greater than the length of the upper conveying trough 2, the lower conveying trough The conveying tank 3 is connected with the vibration source 1, the vibration source drives the lower conveying groove to vibrate, and the upper conveying groove vibrates together under the driving of the lower conveying groove.
[0024] Because the working environment is a high-temperature condition, in order to make the service life of the upper conveyor tank and the lower conveyor tank longer, the two side walls of the upper conveyor tank 2 and the two side walls of the lower conveyor tank 3 are provided with water cooling components; The water-cooled...

The invention discloses a novel scrap steel feeding vibration conveying device which comprises a vibration source and at least two layers of conveying grooves, the conveying grooves are horizontally stacked in sequence, in every two adjacent conveying grooves, the length of the conveying groove located on the upper layer is smaller than that of the conveying groove located on the lower layer, andthe conveying groove located in the lowermost layer is connected with the vibration source. Scrap steel is conveyed and heated through a double-layer conveying channel, the conveying amount of the scrap steel is greatly increased compared with a single conveying channel, and the double-layer conveying channel shares the vibration source and the electric furnace, so that the flowing speed of high-temperature gas in a preheating channel can be reduced to a certain extent through the double-layer conveying grooves, the contact time of the high-temperature airflow and the scrap steel can be prolonged, the preheating effect is good, two conveying grooves are provided with independent feeding openings and pressing mechanisms, feeding and pressing can be conducted independently, only the vibration source is shared, and the scrap steel conveyed in the upper-layer conveying groove is conveyed to fall onto the lower-layer conveying groove.
Description
technical field [0001] The invention belongs to the technical field of scrap steel preheating, and in particular relates to a novel scrap steel feeding vibration conveying device. Background technique [0002] In the process of steelmaking, the preheating of scrap steel is a necessary procedure. The existing scrap steel heating uses a single-channel horizontal vibration conveying method, and the scrap steel conveying capacity is limited, and the high-temperature flue gas generated by the electric furnace acts as a preheating channel in a single vibrating conveying trough. The speed of internal circulation is relatively fast, so that the contact time and contact area between scrap steel and high-temperature flue gas are limited, and it is impossible to efficiently preheat scrap steel. Contents of the invention [0003] The present invention aims to solve the technical problem that the existing steel scrap adopts single-channel conveying and preheating, the conveying amount ...
