Description

Technical Field

[0001] This utility model relates to an anti-clogging chute, specifically a chute located at the end of a belt conveyor that can prevent material blockage, belonging to the technical field of anti-clogging chute equipment. Background Technology

[0002] Belt conveyors are common and essential equipment in the feeding, screening, weighing, and charging systems of blast furnaces for ironmaking. They bear the primary responsibility of transporting raw materials to the blast furnace. In the high-yield, fast-paced, continuous production mode of blast furnaces, if the raw material supply is not smooth, it can lead to production disruptions such as reduced blast, shutdown, and abnormal furnace conditions, or even production and safety accidents. Currently, material blockages sometimes occur in the chutes at the end of belt conveyors. If these blockages are not cleared in a timely manner, blast furnace production will be affected. Currently, the clearing of blockages in the end chutes of belt conveyors is done manually. The drawbacks of manual clearing are: the inability to detect blockages promptly, and the low efficiency of manual clearing, meaning that once a blockage occurs in the end chute, it will affect blast furnace production to some extent. Therefore, a chute that can clear blockages promptly is needed. Utility Model Content

[0018] See Figure 1 , 2 3, 4 and Figure 5This utility model includes a square frame 1, a first inclined plate 2, a second inclined plate 3, a side plate 4, a sensing part, and a material passage part. The square frame 1 is set on the ground by a bracket and is located directly below the end of the belt conveyor 19. To make the structure of this device clearer, the bracket on the square frame 1 is not shown in the attached drawings. The material on the belt conveyor falls at the end and falls freely into the chute composed of the square frame 1, the first inclined plate 2, the second inclined plate 3, and the side plate 4. There are two side plates 4, which are respectively set between the two sides of the first inclined plate 2 and the second inclined plate 3. The combination of the first inclined plate 2, the second inclined plate 3, and the two side plates 4 is funnel-shaped, and the top of the combination matches and connects with the bottom end of the square frame 1. The sensing part is set on the side wall of the first inclined plate 2, and the material passage part is set on the side wall of the second inclined plate 3. The sensing part can sense whether the chute of the combination is blocked, and the material passage part is used to clear the blockage.

[0019] The sensing component includes a return chute 5, a baffle 6, a first support plate, a reset component, and a sensing component. A square hole is provided on the side wall of the square frame 1, and a return chute 5 is provided on the outer wall of the first inclined plate 2. The top of the return chute 5 is located directly below the square hole of the square frame 1, and the bottom surface of the return chute 5 is flush with the bottom surface of the first inclined plate 2. When material overflows from the square hole of the square frame 1, it pushes the baffle 6 to flip, and the overflowing material naturally returns through the return chute 5. There are two first support plates, both located on the outer wall of the square frame 1, with each first support plate positioned on either side of the square hole of the square frame 1. The two first support plates are axially connected. A rotating shaft is provided, and a baffle 6 is mounted on the rotating shaft. The design of the rotating shaft allows the baffle 6 to rotate when pushed by overflowing material. The baffle 6 blocks the outside of the square frame 1. When there is no material blockage, no overflow will occur from the square hole of the square frame 1, and the baffle 6 will not be pushed to trigger the signal of the pressure sensor 9. There are two reset components, which are symmetrically arranged on both sides of the baffle 6. The sensing element is located on the square frame 1 and is located directly above the baffle 6. When there is no overflow pushing the baffle 6, the reset components can drive the baffle 6 to return to its initial position, which is the position where the baffle 6 covers the square hole of the square frame 1.

[0020] The reset component includes a second support plate and a first spring 7; the second support plate is disposed on the outer wall of the square frame 1 and is located on one side of the baffle 6; the first spring 7 is connected between the bottom end of the side wall of the baffle 6 and the second support plate; when the push plate is pushed and flipped by the overflow, the first spring 7 is stretched, and the push plate receives the pulling force from the first spring 7. Only when the overflow disappears, the pushing force opposing the first spring 7 disappears, and the first spring 7 pulls the baffle 6 to reset.

[0021] The sensing element includes a slant rod 8 and a pressure sensor 9; the top of the slant rod 8 is located on the outer wall of the square frame 1, and the slant rod 8 is located directly above the baffle 6; the pressure sensor 9 is located at the bottom end of the end face of the slant rod 8 near the baffle 6, and the signal output terminal of the pressure sensor 9 is connected to the signal input terminal of the CPU; when the baffle 6 is pushed and flipped by overflowing material, its flipping will trigger the signal of the pressure sensor 9. Once the pressure sensor 9 is triggered, it indicates that the chute is blocked, and the material passage section is then activated to clear the blockage.

[0022] The material feeding section includes a feeding mechanism and a striking mechanism; the striking mechanism includes a slide rail 10, a horizontal plate 11, a rope puller 12, an infrared rangefinder, a long slider 13, and a hydraulic cylinder 14; there are two slide rails 10, which are arranged parallel to each other on the outer wall of the second inclined plate 3; there are two long sliders 13, which are slidably arranged on different slide rails 10; the hydraulic cylinder 14 is located between the two long sliders 13; the horizontal plate 11 is located on the bottom end face of the outer wall of the square frame 1, and it is located directly above the slide rail 10; the top surface of the horizontal plate 11 is provided with a rope puller 12, and the rope end of the rope puller 12 is connected to the housing of the hydraulic cylinder 14; the material feeding is carried by the traction of the rope puller 12. The lifting and lowering of the hydraulic cylinder 14 is guided by the long sliders 13 on both sides of the hydraulic cylinder 14; the infrared rangefinder is set on the bottom surface of the horizontal plate 11, and its infrared emitting end points towards the hydraulic cylinder 14; the infrared rangefinder can monitor the position of the hydraulic cylinder 14 in real time, and thus accurately control the hydraulic cylinder to move to the front of each end plate 17; the signal input ends of the rope puller 12 and the hydraulic cylinder 14 are both connected to the signal output end of the CPU; the signal output end of the infrared rangefinder is connected to the signal input end of the CPU; there are multiple material feeding mechanisms, and they are equidistantly arranged on the outer wall of the second inclined plate 3 along the length direction of the slide rail 10, with each material feeding mechanism located between two slide rails 10.

[0023] The material feeding mechanism includes a round rod 15, a conical head 16, an end plate 17, and a second spring 18. A round hole is provided on the side wall of the second inclined plate 3, and the round rod 15 is inserted into the round hole of the second inclined plate 3. The inner diameter of the round hole is the same as the outer diameter of the round rod 15. The axis of the piston rod of the hydraulic cylinder 14 is parallel to the axis of the round rod 15. A conical head 16 is provided at one end of the round rod 15 away from the hydraulic cylinder 14. The maximum outer diameter of the conical head 16 is larger than the outer diameter of the round rod 15. An end plate 17 is provided at the other end of the round rod 15, and a second spring 18 is provided between the end plate 17 and the second inclined plate 3. The movement of the round rod 15 drives the synchronous movement of the conical head 16. Through the movement of the conical head 16 within the chute, the conical head 16 breaks up the blocked material, breaking the original blocking stress structure. After the round rod 15 is pushed out, it is reset by the second spring 18.

[0024] The CPU module in this invention is model 87C196KC.

[0025] Operating principle: When a blockage occurs in the chute composed of square frame 1, first inclined plate 2, second inclined plate 3, and side plate 4, the material accumulates and rises within the chute until it reaches the height of the square hole in square frame 1. At this point, the material overflows from the square hole, pushing baffle 6 and falling back to the end of the chute via a return chute. The overflowing material pushes baffle 6 to press pressure sensor 9, triggering its signal. At this time, rope puller 12 actuates, causing hydraulic cylinder 14 to adjust its position. Using an infrared rangefinder in conjunction with rope puller 12, the hydraulic cylinder is moved to the front of the lowest end plate 17. Then, the hydraulic cylinder is activated, extending... The piston rod pushes the end plate 17, the round rod 15, and the conical head 16 forward. The conical head 16 pokes the blocked material in the chute. After the hydraulic cylinder extends the piston rod to its end, it retracts the piston rod. At this time, the end plate 17 is reset under the action of the second spring 18. This is repeated three times. If the pressure sensor 9 is still triggered, it means that the blockage has not been cleared. At this time, the rope puller 12 pulls the hydraulic cylinder up to the next end plate 17 and repeats the above action. From bottom to top, each end plate 17 is pushed three times in sequence until the pressure sensor 9 is no longer triggered, indicating that the material has been cleared. At this time, the hydraulic cylinder and the rope puller 12 are shut off and no longer operate. The chute blockage clearing operation is now complete.
