The sintering process is from material distribution ignition sintering to new generation of new bedding materials and warehousing for about 3 hours, and the fully-stored bedding material warehouse can only maintain the sintering machine to produce the bedding materials for about 1 hour due to the limited warehouse space of the bedding material warehouse. And when the sintering ores on the sintering machine and the cooling machine are emptied, the bedding material of each sintering machine is produced without bedding material for more than 2.5 hours in a self-production and self-use mode, and even if the bedding material of the bedding material bin is full before overhauling, the sintering machine still faces to the production without bedding material for more than 1.5 hours. The production of the non-bedding material directly brings the problems of poor air permeability of the material layer, grate burning loss, fluctuation of the sintering process and the like.

The utility model can ensure that the sintering machine realizes the production of full bedding materials. The method has the following defects: when the device is used, the device needs to be matched with a manual hoist for operation, and the control of the material quantity of the material distributing plate of the distributor is adjusted by adjusting the manual hoist.

Example 1

Referring to fig. 1, the present embodiment provides a two-way feeding system for a base material of a sintering machine, which includes a plurality of non-reversible belt conveyors, a reversible belt conveyor 4, two guide tanks, a plugboard 9 and two base material spreading bins, and specifically includes a guide tank i 1, a guide tank ii 2, a reversible belt conveyor 4, a non-reversible belt conveyor i 5, a non-reversible belt conveyor ii 6, a non-reversible belt conveyor iii 7, a non-reversible belt conveyor iv 8, a plugboard 9, a base material spreading bin i 10 and a base material spreading bin ii 11. Wherein, irreversible type belt conveyer III 7, irreversible type belt conveyer IV 8, reversible type belt conveyer 4, baffle box I1 and baffle box II 2 are located same three-dimensional plane, and irreversible type belt conveyer III 7 and irreversible type belt conveyer IV 8, baffle box I1 and baffle box II 2 symmetry respectively arrange. The reversible belt conveyor 3 is positioned above the irreversible belt conveyor III 7 and the irreversible belt conveyor IV 8, and the head wheel and the tail wheel of the reversible belt conveyor are respectively connected with the discharging channel of the guide chute I1 and the discharging channel of the guide chute II 2. The guide chute I1 and the guide chute II 2 are inverted V-shaped guide chute, which is called as a underpants guide chute in the industry, two feed openings 3 of the guide chute I1 are respectively communicated with a non-reversible belt conveyor III 7 and a reversible belt conveyor 4, the length of the non-reversible belt conveyor III 7 is larger than the distance between the two feed openings of the guide chute I1, and the non-reversible belt conveyor III 7 is used for conveying materials into a bottom paving bin I10; the two discharging openings of the guide chute II 2 are respectively communicated with the non-reversible belt conveyor IV 8 and the reversible belt conveyor 4, the length of the non-reversible belt conveyor IV 8 is larger than the distance between the two discharging openings of the guide chute II 2, and the non-reversible belt conveyor IV 8 is used for conveying materials into the bedding bin II 11; the non-reversible belt conveyor I5 and the non-reversible belt conveyor II 6 are respectively positioned above the guide chute I1 and the guide chute II 2, and the feed opening of the non-reversible belt conveyor I5 and the non-reversible belt conveyor II 6 are respectively communicated with the feed opening of the guide chute I1 and the feed opening of the guide chute II 2, so that materials are conveyed in the guide chute I1 and the guide chute II 2.

Further, the feed openings adjacent to the guide chute I1 and the guide chute II 2 are inwards bent, so that the head pulley and the tail pulley of the reversible belt conveyor 3 are convenient to install.

Further, the upper parts of the feed openings 3 adjacent to the guide chute I1 and the guide chute II 2 are respectively provided with a plugboard 9, so that the reversible belt conveyor 4 can be overhauled conveniently.

If the sintering machine is in normal production, the reversible belt conveyor 4 is in a stop state, the plugboards 9 on the vent funnels of the guide chute I1 and the guide chute II 2 are opened (when the reversible belt conveyor 4 does not need to be overhauled, the plugboards 9 can be in a normally open state). And the different sintering machines can realize the self-production and self-use of the bedding materials by feeding the produced bedding materials into the bedding material bins.

When the bedding amount of one sintering machine cannot meet the requirement, after the direction of the belt conveyor to be operated is selected on site or remotely before starting, the reversible belt conveyor 4 is started on site or remotely, so that the bedding materials can be simultaneously supplied to the two sintering machines; if the quick feeding to one sintering machine is required, only the irreversible belt conveyor III 7 or the irreversible belt conveyor IV 8 is required to be stopped, and when the material guide groove I1 or the material guide groove II 2 is full of a section of underpants hopper of the reversible belt conveyor 4, all the bedding material flow is automatically supplied to the other sintering machine.
