[0002] During the ironmaking process of a blast furnace, it is often necessary to distribute coke and other materials into silos, which requires the installation of a material distribution device on the original belt conveyor. In the prior art, a material distribution seat for guiding materials to both sides is generally provided above the belt conveyor, and a lifting device is used to lift or lower the material distribution seat. The material distribution seat is a component that is approximately triangular and can be dropped onto the belt conveyor to guide the materials to both sides into two chutes. At this time, the coke can enter the conveyor belt below through the chute. When material distribution is not required, the lifting device needs to be used to lift the material distribution seat to the top to separate it from the belt conveyor. At this time, the coke will be directly transported to the silo.

[0023] Please also read Figure 1 to Figure 2 Now, the material conveying and dividing structure provided by the utility model is described. The material conveying and distributing structure comprises a frame 1, a first conveyor belt 2, a distributing hopper 3, two chutes 4 and a second conveyor belt 5. The frame 1 is rotatably connected with a first guide roller 11 for guiding the material on the first conveyor belt 2 to the upper opening of the distributing hopper 3 and a second guide roller 12 located below and behind the first guide roller 11 and used to guide the first conveyor belt 2 to be transferred to the lower part of the distributing hopper 3. The first conveyor belt 2 is sequentially wound around the front side of the first guide roller 11 and the rear side of the second guide roller 12. The lower opening of the distributing hopper 3 is open. The two chutes 4 are symmetrically connected to the lower sides of the distributing hopper 3. The second conveyor belt 5 is located below the chute 4. Two distributing flaps 31 corresponding to the two chutes 4 are hinged in the distributing hopper 3. The distributing flap 31 is used to open the chute 4 to allow the material in the distributing hopper 3 to enter the chute 4, or to block the chute 4 to allow the material to fall onto the first conveyor belt 2 in front of the second guide roller 12.

[0024] Compared with the prior art, the material conveying and dividing structure provided in the present embodiment has a first guide roller 11 arranged on the frame 1 to guide the material into the dividing hopper 3, and a second guide roller 12 is arranged to guide the front end of the first conveyor belt 2 to the bottom of the dividing hopper 3, so as to facilitate the position adjustment of the dividing flap 31 according to the material demand of the second conveyor belt 5, thereby achieving the effect of opening or closing the chute 4, and achieving different effects of supplying the material in the dividing hopper 3 to the second conveyor belt 5 or the first conveyor belt 2, so as to facilitate the continuous operation of the equipment, avoid shutdown and maintenance caused by structural wear, and realize stable production operation.

[0025] For the convenience of description, the direction in which the first conveyor belt 2 runs is defined as the front side, and the direction in which the first conveyor belt 2 comes from is defined as the rear side.

[0026] In this embodiment, when materials are needed on the second conveyor belt 5, the material distribution flaps 31 swing to positions close to each other to open the upper opening of the chute 4, and at the same time close the lower opening of the distribution hopper 3 to prevent materials from falling onto the first conveyor belt 2 in front of the second guide roller 12. When materials are not needed on the second conveyor belt 5, the material distribution flaps 31 swing to positions away from each other to block the upper opening of the chute 4, and at this time the lower opening of the distribution hopper 3 is open, and the materials fall onto the first conveyor belt 2 in front of the second guide roller 12. The above structure is convenient for switching between the two feeding states, with less wear on the structure, no frequent equipment maintenance and replacement of wear parts are required, and the stability of equipment operation is improved.

[0027] In one possible implementation, see Figure 1 to Figure 2 A lap shaft 32 extending in the front-rear direction is provided in the material distribution hopper 3, and the swing end of the material distribution flap 31 can be vertically swung to overlap the peripheral wall of the lap shaft 32 to open the upper opening of the chute 4.

[0028] In this embodiment, in order to facilitate smooth switching between the two states of opening the chute 4 and closing the lower opening of the distribution hopper 3 and closing the chute 4 and opening the lower opening of the distribution hopper 3, the distribution flap 31 is arranged on the side adjacent to the two chutes 4. By arranging a lap shaft 32 in the distribution hopper 3, the swinging end of the distribution flap 31 is conveniently overlapped on the lap shaft 32, thereby achieving effective blocking of the lower opening of the distribution hopper 3, ensuring effective communication between the upper opening of the chute 4 and the distribution hopper 3, and allowing the material to smoothly fall through the two chutes 4 to the second conveyor belt 5 below.

[0029] On this basis, a lap strip 33 capable of limiting the swinging end of the material distribution flap 31 is provided on the inner wall of the chute 4 to limit the position of the material distribution flap 31 and avoid wear caused by contact between the material distribution flap 31 and the inner wall of the chute 4.

[0030] In some embodiments, see Figure 1 to Figure 2, the sub-hopper 3 extends downward to below the upper opening of the chute 4, and the lower opening of the sub-hopper 3 gradually closes. The sub-hopper 3 extends downward, so that the height can be lowered to a position closer to the first conveyor belt 2 in front of the second guide roller 12, so that the material can smoothly fall onto the first conveyor belt 2, and the material can be effectively received. The lower opening of the sub-hopper 3 closes, which can effectively gather the material above the first conveyor belt 2 to prevent the material from leaking out.

[0031] In one possible implementation, see Figure 1 to Figure 2 The chute 4 includes an upper chute portion 41 connected to the frame 1 and a lower chute portion 42 connected below the upper chute portion 41. The upper chute portions 41 of the two chutes 4 extend obliquely from top to bottom toward opposite sides, and the lower chute portions 42 of the two chutes 4 extend from top to bottom toward adjacent sides.

[0032] In this embodiment, the upper chute portion 41 and the lower chute portion 42 are connected up and down to form the chute 4, which can effectively avoid the first conveyor belt 2 in front of the second guide roller 12. On this basis, the cross-sectional area of ​​the lower chute portion 42 gradually increases from top to bottom. It can effectively disperse the materials, improve the transportation efficiency of the materials, avoid blockage problems, and ensure the smooth flow of the materials.

[0033] In one possible implementation, see Figure 1 to Figure 2 The lower parts of the two lower chute parts 42 are connected with a receiving barrel 43, and the upper openings of the receiving barrel 43 are respectively connected with the lower openings of the two lower chute parts 42. The receiving barrel 43 connected at the lower ends of the two lower chute parts 42 can concentrate the materials in the two chutes 4, and the inner cavity of the receiving barrel 43 is larger than that of the lower chute part 42, so as to realize the smooth supply of materials.

[0034] In some embodiments, see Figure 1 to Figure 2 The side walls of the receiving barrel 43 are respectively gathered inward from top to bottom, so that the lower end of the receiving barrel 43 forms a gathering effect, which is convenient for concentrating the materials above the second conveyor belt 5. The size of the receiving barrel 43 in the width direction of the second conveyor belt 5 should be smaller than the width of the second conveyor belt 5 to avoid leakage of materials from both sides of the second conveyor belt 5.

[0035] In one possible implementation, see Figure 1 to Figure 2 , the rear side wall of the material distribution hopper 3 gradually extends from bottom to top toward the side close to the first guide roller 11. When the material distribution hopper 3 receives the material on the first conveyor belt 2 behind the first guide roller 11, in order to prevent the material on the peripheral wall of the first conveyor roller from falling to the outside of the material distribution hopper 3, the rear side wall of the material distribution hopper 3 gradually tilts toward the rear side (that is, tilts toward the direction of the first conveyor belt 2), which can effectively receive the material supplied by the first conveyor belt 2 and avoid spillage of the material.

[0036] In one possible implementation, see Figure 1 to Figure 2There is a certain angle between the direction of the second conveyor belt 5 and the direction of the first conveyor belt 2, which can realize the orderly reversal of the material. Specifically, the direction of the second conveyor belt 5 is perpendicular to the direction of the first conveyor belt 2, which meets the material transportation requirements.

[0037] In one possible implementation, see Figure 1 to Figure 2 A horizontally extending support roller 21 and two side guard rollers 22 are respectively arranged on both sides of the support roller 21 below the first conveyor belt 2 and the second conveyor belt 5, and the outer ends of the side guard rollers 22 gradually extend upward.

[0038] In this embodiment, the first conveyor belt 2 and the second conveyor belt 5 utilize the supporting rollers 21 below to mainly support the materials, and the side blocking rollers 22 on both sides can effectively gather the materials to prevent the materials from leaking to both sides, thereby realizing the orderly transportation of materials, avoiding the loss of materials, ensuring the stability and reliability of material transportation, and helping to improve the transportation efficiency of materials.

[0039] Usage process:

[0040] When materials are needed on the second conveyor belt 5 , the material distribution flaps 31 swing close to each other to open the upper opening of the chute 4 , while closing the lower opening of the distribution hopper 3 to prevent materials from falling onto the first conveyor belt 2 in front of the second guide roller 12 .

[0041] When the second conveyor belt 5 does not need materials, the material distribution flaps 31 swing away from each other to block the upper opening of the chute 4. At this time, the lower opening of the distribution hopper 3 is open, and the materials fall onto the first conveyor belt 2 in front of the second guide roller 12. The above structure is convenient for switching between the two feeding states, with less wear on the structure, no need for frequent equipment maintenance and replacement of worn parts, and improves the stability of equipment operation.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
