Technical Field
The utility model belongs to the technical field of the iron and steel smelting technique and specifically relates to a feeding device for giving double-chamber kiln is reinforced.
Background
In the operation process of steel smelting production, the vibrating feeder is started by the lower end of a lime stone bin in front of a kiln and a belt in front of the kiln, and the lime stone raw material is conveyed into a weighing hopper in front of the kiln to be weighed. As shown in attached figures 1 to 3, when the weight of the interior of the weighing hopper 1 in front of the kiln reaches a set weight value, and the single-bucket trolley 3 reaches the bottom of the inclined bridge track 4, the gate plate 2 at the bottom of the weighing hopper in front of the kiln is opened, and limestone raw materials are placed in the single-bucket trolley 3. Under the action of the winch, the single-bucket trolley 3 pours the limestone raw material into the kiln top weighing hopper 5.
When one kiln chamber of the double-chamber kiln is calcined, the other heat-accumulating kiln chamber is fed under the control of the system, namely when the No. 1 chamber of the double-chamber kiln is calcined, the system needs to feed into the heat-accumulating chamber 2. At the moment, limestone raw materials enter a first kiln top vibrating feeder 6 from a kiln top weighing hopper 5 through a single-pass receiving port 12 and are conveyed to a second rotating hopper 9 corresponding to the top of the kiln barrel of the chamber No. 2 through a bidirectional belt 7. In the feeding process, in order to ensure that the second rotary hopper 9 is filled with enough stones and keep the material level horizontal, a motor of the second rotary hopper 9 drives a speed reducer to rotate the second rotary hopper 9; when the set weight in the second rotary hopper 9 is reached, the first kiln top vibrating feeder 6, the bidirectional belt 7 and the rotary hopper stop running. When the charging time set by the system is up, a kiln cylinder closing cover plate of the chamber 2, namely a second kiln cylinder closing cover plate 11 is opened, and the limestone raw materials in the hopper are downwards put into the chamber 2 of the double-chamber kiln by the second rotary hopper 9 under the action of the hydraulic cylinder (as shown in figure 1). After the feeding is finished, the second rotary hopper 9 is lifted upwards, and then the kiln cylinder closing cover plate of the No. 2 chamber, namely the second kiln cylinder closing cover plate 11 is closed. Thus, in one combustion period, feeding is realized for 2-3 times.
When the double-hearth kiln is reversed, the original hearth 1 is changed into a heat storage hearth, the system changes the running direction of the bidirectional belt 7, and the materials are fed into the first rotary hopper 8 of the hearth 1 (shown in attached figures 2 and 3). Because the length of the bidirectional belt is short, the reversing belt on the kiln top needs to be continuously switched to the running direction, so that the requirement of respectively feeding materials to two kiln cylinders in different running periods is met, and the feeding mode has the problems that the reversing belt is easy to deflect, stone slag falls off from the bottom of a carrier roller, the belt is easy to tear, the equipment is difficult to maintain and the like; increasing the field labor intensity and the equipment maintenance frequency.
