Rotary feeding device of sinter cooling furnace

Abstract

A rotary feeding device of a sinter cooling furnace relates to the sinter cooling and waste-heat utilization field. The feeding device is arranged at a furnace opening of the cooling furnace; a transmission device comprises a motor, a rotary shaft, a driving gear, driven gears, a transmission shaft, protective covers and a supporting frame; the feeding device comprises a feeding cover, a feeding hole, a screw feeder, a discharging hole and a cone-shaped charging bell; the motor is connected with one end of the rotary shaft; the other end of the rotary shaft is connected with the driving gear; the driving gear and the driven gears which are arranged on the periphery of the transmission shaft are meshed with each other; the protective covers are externally arranged on the driving gear, the transmission shaft and the driven gears; the supporting frame which is fixed on the feeding cover is arranged below the protective covers; the feeding cover is coated outside the furnace opening of the cooling furnace; the transmission shaft penetrates through the feeding cover to be connected with the screw feeder; the feeding hole is formed on the lateral portion of the feeding cover; the discharging hole is formed at the bottom of the feeding cover; and the cone-shaped feeding bell is arranged under the feeding cover. The rotary feeding device of the sinter cooling furnace has the advantages of being convenient to use and capable of providing materials for the sinter, enabling the distribution of the sinter to be uniform and being good in sealing performance.

Description

technical field [0001] The invention relates to the fields of sinter cooling and waste heat utilization, in particular to a rotary feeding device for a sinter cooling furnace. Background technique [0002] In the process of iron and steel production, the energy consumption of sintering process accounts for about 9-12% of the total energy consumption, second only to the ironmaking process, and the energy saving of sintering occupies a very important position in the energy saving of iron and steel enterprises. The sensible heat of hot sinter and sinter flue gas accounts for more than 40% of the heat consumption in the sintering process. Making full use of this part of waste heat is an important aspect of sintering energy saving. The need to improve the competitiveness of enterprises. [0003] At present, the sinter cooling and waste heat recovery and utilization in my country mainly adopt ring cooling or belt cooling technology, and the waste heat utilization has the followin...
