[0002] See also Figure 1 When the ironmaking plant produces sintered ore, the fuel falls from the fuel silo 1 onto the fuel conveying belt 3, and then is transferred to the mixing belt 6 via the fuel conveying belt 3. On the mixing belt 6, the fuel, iron-containing raw materials, and solvents added in different proportions are mixed evenly and granulated with water, and then transported to the sintering machine ignition furnace 7 for sintering. After sintering, the sintered ore with qualified quality is transported to the blast furnace for ironmaking.
[0003] Whether the fuel system discharges materials stably directly determines the burning quality of sintered ore. The fuel in the fuel silo 1 may sometimes accumulate, causing unstable discharge and material breakage, which in turn affects product quality. Since the discharge station has a large operation area, manual maintenance and elimination work bring considerable work intensity to the workers. Therefore, the industry urgently needs a fuel delivery device that can automatically prevent material shortage when producing sintered ore. Utility Model Content

[0016] The utility model discloses a fuel conveying device for automatically preventing material shortage when producing sintered ore. Figure 1As shown, it includes a fuel silo 1, a vibration motor 2, a fuel conveying belt 3, a material shortage detection mechanism 4, and an electrical control cabinet 5; there are two vibration motors, which are symmetrically arranged on the inner wall of the fuel silo. Under normal circumstances, the fuel in the silo naturally falls onto the fuel conveying belt from the silo discharge port under the action of its own gravity. When the fuel in the silo is silted, it is necessary to start the vibration motor. The above-mentioned material shortage detection mechanism 4 is arranged on the fuel conveying belt chassis 3-2, located below the upper belt 3-1 of the fuel conveying belt. The electrical control cabinet 5 is connected to the vibration motor 2 and the material shortage detection mechanism 4 through cables for signal transmission. When the material shortage detection mechanism 4 detects that the upper belt 3-1 of the fuel conveying belt moves up due to lack of material, the electrical control cabinet 5 starts the vibration motor.
[0017] The utility model discloses a fuel conveying device for automatically preventing material shortage when producing sintered ore, the material shortage detection mechanism 4 comprises a roller 4-1, an upper and lower slide plate 4-2, a slide seat 4-3, a spring 4-4, a spring bracket 4-5, an induction switch 4-6, and an induction plate 4-7; the slide seat 4-3 and the induction switch 4-6 are both mounted on a fuel conveying belt chassis 3-2, the upper and lower slide plates 4-2 are movably mounted on the slide seat 4-3, the roller 4-1 is rotatably mounted on the top of the upper and lower slide plates 4-2 through a rotating shaft, the roller 4-1 presses upward against the lower surface of the upper belt 3-1 of the fuel conveying belt, the spring bracket 4-5 is fixedly mounted on the lower part of the upper and lower slide plates 4-2, the spring 4-4 is a tension spring, the upper and lower ends of which are respectively hooked on the slide seat 4-3 and the spring bracket 4-5, the induction plate 4-7 is mounted on the upper and lower slide plates 4-2,
[0018] The utility model discloses a fuel conveying device which can automatically prevent material shortage when producing sintered ore. The upper and lower slide plates 4-2 and the slide seat 4-3 are connected by slide blocks and slideways, and the slideways are in the form of dovetail grooves.
[0019] The utility model discloses a fuel conveying device for automatically preventing material shortage when producing sintered ore. In order to adapt to different fuel conditions, the induction plates 4-7 are arranged to be adjustable in upper and lower positions.
[0020] The working principle of the utility model is that when the fuel in the fuel silt 1 is silted, the fuel on the fuel conveying belt 3 will be reduced or cut off. At this time, the gravity of the fuel borne by the belt is reduced, the belt moves upward, and the upper and lower slide plates 4-2 move upward under the pulling force of the spring 4-4. The induction plate 4-7 approaches the induction switch 4-6. At this time, the induction switch 4-6 sends an electrical signal, which is transmitted to the electrical control cabinet 5, and then the vibration motor 2 is started to work to vibrate and eliminate silt. After the vibration motor is started to eliminate siltation, the material falling returns to normal, and the lack of material detection mechanism 4 performs an action opposite to the above action. At this time, the electrical control cabinet stops the vibration motor.
