Description

Technical Field

[0001] The utility model relates to the technical field of coal feeders, and more specifically to a coal feeder with an anti-blocking function. Background Art

[0002] A coal feeder is a mechanical device that can accurately adjust the coal feeding amount of a coal mill according to the load requirement. It is arranged between the raw coal bunker and the coal mill. In a direct-fired pulverized coal system, the coal feeding amount is directly adapted to the boiler load. There are various types of coal feeders, which are divided into volumetric type and gravity type according to the structural characteristics and working principles, and belong to a part of the blast furnace ironmaking technology field.

[0003] When the existing coal feeder discharges materials after crushing coal, the coal accumulation is likely to block the discharge port. If it is not dredged in time, it is easy to cause damage to the coal feeder and reduce the coal output efficiency. Based on this, the utility model designs a coal feeder with an anti-blocking function to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a coal feeder with an anti-blocking function to solve the problems existing in the above background art.

[0005] The utility model provides the following technical solutions: A coal feeder with an anti-blocking function includes a box body. A motor is fixedly installed on the outer wall of the box body. The output end of the motor is fixedly connected with a rotating shaft. A rotating cylinder is fixedly connected to the outer wall of the rotating shaft. A plurality of knife plates are fixedly connected to the outer wall of the rotating cylinder. A sloping plate is fixedly connected to the inner wall of the box body corresponding to the knife plates. A sliding plate is slidably connected to the inner wall of the box body. A rack is fixedly connected to the top end of the sliding plate. The rack meshes with a half gear. A transmission mechanism is arranged on the outer wall of the rotating shaft, and the rotating shaft synchronously drives a rotating rod through the transmission mechanism. A half gear is fixedly connected to the outer wall of the rotating rod. A group of support plates are fixedly connected between the sloping plate and the box body. A plurality of springs are fixedly connected between the support plates and the sliding plate. An outlet is opened at the bottom end of the box body. A plurality of material poking rods are fixedly connected to the end of the sliding plate corresponding to the outlet.

[0006] Further, a feed inlet is opened at the top end of the box body. A maintenance door is opened on the outer wall of the box body. The end of the rotating shaft is rotatably connected to the inner wall of the box body.

[0007] Further, the rotating rod penetrates through the outer wall of the box body and is rotatably connected thereto. The end of the rotating rod is rotatably connected to the inner wall of the box body.

[0008] Further, a chute is opened on the inner wall of the box body corresponding to the sliding plate. The end of the sliding plate is located in the chute and is slidably connected thereto.

[0009] Further, the transmission mechanism includes transmission wheels fixedly connected to the outer walls of the rotating shaft and the rotating rod, and a belt is sleeved between the transmission wheels.

[0010] Technical effects and advantages of the present utility model:

[0011] 1. In the present utility model, cinder enters the box body through the feed inlet, and the connected motor drives the rotating shaft, the rotating cylinder and the knife plate to rotate. The knife plate cooperates with the inclined plate to crush the cinder, breaks larger coal blocks into smaller cinders and discharges them through the discharge outlet.

[0012] 2. In the present utility model, the transmission mechanism drives the rotating rod and the half gear to rotate. The half gear meshes with the rack to drive the slide plate to move upward along the chute and squeeze the spring. When the half gear no longer meshes with the rack, under the action of the spring, the slide plate and the material poking rod are bounced downward along the chute. As the half gear continues to rotate, the material poking rod continuously moves up and down reciprocally, thereby poking the cinder blocked in the box body away from the discharge outlet, avoiding the cinder blocking the discharge outlet and affecting the working efficiency of the coal feeder.

An inclined plate 6 is fixedly connected to the inner wall of the box body 1 corresponding to the knife plates 14. Coal cinder is poured into the box body 1 from the feed inlet 5. Connect the motor 2 to drive the rotating shaft 13, the rotating cylinder 15 and the knife plates 14 to rotate. The knife plates 14 cooperate with the inclined plate 6 to crush the coal cinder, break the larger coal blocks into smaller coal cinders and complete the discharging through the discharge port 11. A sliding plate 9 is slidably connected to the inner wall of the box body 1. A chute 10 is opened on the inner wall of the box body 1 corresponding to the sliding plate 9. The end of the sliding plate 9 is located in the chute 10 and is slidably connected thereto. A rack 16 is fixedly connected to the top of the sliding plate 9. The rack 16 meshes with a half gear 17. A transmission mechanism 18 is provided on the outer wall of the rotating shaft 13, and the rotating shaft 13 synchronously drives a rotating rod 3 through the transmission mechanism 18.
