Description

TECHNICAL FIELD

[0001] The utility model relates to ironmaking blast furnace sintered raw material production equipment technical field especially relates to a belt feeder anti -stuffing device. BACKGROUND

[0002] The raw material of the ironmaking blast furnace in the steel metallurgical industry, such as finished sintered ore, coke, lump ore, pellet and other solvents, is generally transported by a belt feeder. In order to prevent the raw material from splashing when it is output from the output end of the belt feeder, a discharge hopper is provided at the output end of the belt feeder, and the output end of the belt feeder is located in the discharge hopper. Although the discharge hopper can guide the output of the raw material, due to the tubular structure, there are large pieces of material, impurities or too wet and sticky material in the blast furnace raw material, which causes the raw material to be easily blocked in the discharge hopper with a tubular structure, causing the discharge hopper of the belt feeder to be blocked. If the belt feeder discharge hopper blocking condition cannot be found in time, not only will it cause the belt feeder to stop working, affecting the transportation of the material, but the blocked material will also overflow and bury the downstream belt feeder, which requires a lot of manpower to clean up.

[0005] Further, an observation port is formed in the blocking material collection hopper, and a movable door is installed on the observation port. The movable door can be easily opened to observe the blocking condition of the upstream belt feeder and to clean the blocking material in the blocking material collection hopper.

[0006] Further, the observation port is obliquely upwardly arranged, the top of the movable door is hingedly arranged on the blockage collecting hopper, and the bottom of the movable door is buckled on the blockage collecting hopper. The observation port obliquely upwardly arranged, on the one hand, does not cause the blockage collecting hopper to leak material; on the other hand, the movable door can be directly buckled on the blockage collecting hopper by gravity, the buckling of the movable door is more reliable, and meanwhile, the observation of the blockage condition in the blockage collecting hopper is facilitated.

[0007] Further, a door handle is arranged on the movable door. The arrangement of the door handle facilitates the opening and closing operation of the movable door.

[0010] Further, the blockage outlet of the blockage collecting hopper is close to the downstream belt feeder. The blockage in the blockage collecting hopper falling on the downstream belt feeder can be effectively prevented from splashing, and the accuracy of the material falling is improved.

[0011] Further, the proximity switch and the upstream belt feeder are electrically connected with a control unit respectively. In working, the proximity switch detects the swing position of the upstream belt feeder, and the control unit controls the upstream belt feeder according to the swing position of the upstream belt feeder detected by the proximity switch. For example, when the proximity switch detects the swing position of the upstream belt feeder, it is judged that the upstream belt feeder is opened, and the blockage in the blockage collecting hopper is squeezed in. At this time, the control unit controls the upstream belt feeder to stop. In this way, the upstream belt feeder can be prevented from being damaged due to the blockage.

[0012] The blockage preventing device of the belt feeder can be used for preventing the blockage of the belt feeder. The detection port is arranged on the vertical part of the sidewall of the belt feeder hopper, and the movable baffle is arranged on the detection port. When the belt feeder hopper is blocked, the blocked material can squeeze the movable baffle under the extrusion force, and the movable baffle can swing to the side away from the upstream belt feeder. Meanwhile, the proximity switch is arranged. When the movable baffle swings to the side away from the upstream belt feeder, the proximity switch can detect the position signal of the movable baffle. The position signal detected by the proximity switch can be used to judge whether the belt feeder hopper is blocked during the conveying of the material by the upstream belt feeder. The blockage of the upstream belt feeder can be monitored in real time, and the problems such as the upstream belt feeder being stuck due to the blockage, the downstream belt feeder being buried by the material and needing a large amount of manpower for cleaning and the like can be avoided.

[0013] Meanwhile, the blocking material collecting hopper is arranged, which not only facilitates the installation of the proximity switch, but also guides the blocking material into the blocking material collecting hopper.

[0014] The blocking material outlet of the blocking material collecting hopper is located directly above the downstream belt conveyor, so that the blocking material into the blocking material collecting hopper is guided to the downstream belt conveyor for conveying, and the treatment and cleaning of the blocking material into the blocking material collecting hopper are avoided, thereby greatly saving manpower.
