Description

Technical Field

[0001] The present invention belongs to the technical field of mine material transportation, and particularly relates to a large material crushing and removing device applicable to a belt conveyor for ironmaking.

Background Art

[0002] In the pre-iron sintering process of steel production, the quality of sintering material distribution has a crucial impact on the quality of the final steel product. At present, the method of material distribution using a swing belt widened belt conveyor plus eleven rollers is widely used in ironmaking sintering. As the last process equipment in the material distribution system after batching, mixing and pelletizing, the working condition of the four-mixed belt conveyor is directly related to the quality of sintering material distribution. However, in actual production, due to the complexity of raw material procurement, storage, transportation and other links, large materials often appear on the four-mixed belt conveyor.

[0003] The traditional treatment methods mainly include manual inspection and the use of simple mechanical devices. Manual inspection relies on the experience and responsibility of operators, with low efficiency and it is difficult to ensure timely detection and treatment of all large materials. In the pre-iron sintering production environment, it cannot meet the requirements of high-efficiency production and is prone to production interruption and unstable quality. Simple mechanical devices such as gratings can block some large materials from entering the material distribution system, but they cannot crush and remove them, and the accumulated materials will still affect the normal progress of production.

Summary of the Invention

[0004] The purpose of the present invention is to provide a large material crushing and removing device applicable to a belt conveyor for ironmaking, so as to solve the problem that large materials on the existing belt conveyor cannot be crushed and removed, affecting normal production.

[0005] The present invention adopts the following technical solutions: A large material crushing and removing device applicable to a belt conveyor for ironmaking, including an I-beam crossbeam horizontally arranged above the belt conveyor, and the included angle between the extending direction of the I-beam crossbeam and the extending direction of the belt conveyor is an acute angle; a T-shaped baffle is arranged at the bottom of the crossbeam, and the web of the T-shaped baffle is horizontally arranged; two lead screws are vertically and spaced apart through the upper and lower flange plates of the crossbeam, and two nuts threadedly connected to the two lead screws are both fixedly arranged on the upper flange plate; the lower end of each lead screw passes through the flange plate and is connected to the web of the T-shaped baffle; at least three baffle teeth are spaced apart on the web, and each baffle tooth is a vertically arranged plate structure;

[0006] Wherein, the lead screw is used to drive the T-shaped baffle to move up and down through its lifting; the baffle teeth are used to block large materials transported along with the belt conveyor and make them be impacted and crushed into small pieces for continuous transportation.

[0007] Furthermore, it further includes a baffle, which is vertically arranged at the bottom of the crossbeam and is arranged closely against the flange plate of the T-shaped baffle.

[0008] Further, the included angle between the extending direction of the I-beam crossbeam and the extending direction of the belt conveyor is an acute angle; on the side of the belt conveyor, on the side close to the baffle teeth farthest from the feeding direction of the belt conveyor, there are two receiving inclined plates, which are respectively located on both sides of the baffle teeth along the feeding direction; the receiving inclined plates are arranged obliquely downward for guiding the splashed materials generated when the baffle teeth crush the materials from here.

[0009] Further, it also includes two force-bearing piers. On one of the force-bearing piers, a longitudinal beam is vertically arranged, and the top end of the longitudinal beam is connected to the crossbeam. On the other force-bearing pier, an inclined beam is obliquely arranged, and the end of the inclined beam is connected to the top end of the longitudinal beam.

[0010] Further, at least two fixing blocks are arranged at intervals at the connection between the baffle and the crossbeam.

[0011] The beneficial effects of the present invention are as follows: The large-piece material crushing and removing device of the present invention has many significant beneficial effects. In terms of production efficiency, the device realizes the automatic processing of large-piece materials without frequent manual intervention. In the past, the manual inspection method was inefficient, consuming a large amount of manpower and time, and it was also difficult to ensure the timely discovery and processing of all large-piece materials. However, this device can work continuously for 24 hours, greatly saving time and labor costs, ensuring the continuity of production, and enabling the sintering production to proceed efficiently and stably.

[0012] From the perspective of production cost, due to the high processing capacity of the device, the production failures caused by large-piece materials are reduced, and the equipment maintenance cost and production stoppage losses are lowered. At the same time, the quality problems of sintered ore are also reduced, avoiding the waste caused by unqualified quality, thereby indirectly reducing the production cost and creating greater economic benefits for the enterprise.

[0013] In terms of the quality of the burden distribution, by effectively crushing and removing the large-piece materials on the belt conveyor 1, the phenomenon of uneven burden distribution caused by large-piece materials is avoided. The uniform burden distribution provides a solid technical guarantee for stable and high-quality sintering, improves the quality of sintered ore, makes the quality of the finally produced steel products better, and enhances the competitiveness of the products in the market.

[0014] The device of the present invention breaks through the disadvantages of low efficiency of manual inspection and the simple mechanical device that can only block large-piece materials but cannot remove them, realizes the automatic processing of large-piece materials, improves the production efficiency and stability, and reduces the production cost.

Specific implementation manner

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0019] The present invention provides a device for crushing and removing large-sized materials applicable to a belt conveyor for ironmaking, as Figure 1 shown. It includes an I-beam cross beam 2 horizontally arranged above the belt conveyor 1. The cross beam 2 is horizontally installed as the main working platform of the device. Its I-shaped structure provides a large bearing area and strength, and can install and support other components. The length of the I-beam cross beam 2 is designed according to the width of the belt conveyor 1 to ensure that it can cover the entire width of the belt conveyor 1 and effectively handle large-sized materials.

[0020] As Figure 2 shown, a T-shaped baffle 4 is provided at the bottom of the cross beam 2, and the web plate 401 of the T-shaped baffle 4 is horizontally arranged; two lead screws 3 are vertically and spaced apart through the upper and lower flange plates 201 of the cross beam 2, and two nuts 7 threadedly connected to the two lead screws 3 are both fixedly arranged on the upper flange plate 201.

[0021] The lower end of each lead screw 3 passes through the flange plate 201 of the cross beam 2 and is connected to the web plate 401 of the T-shaped baffle 4; at least three baffle teeth 6 are spaced apart on the web plate 401, and each baffle tooth 6 is a vertically arranged plate structure.

[0022] Among them, the lead screw 3 is used to drive the T-shaped baffle 4 to move up and down through its lifting; the baffle teeth 6 are used to block the large-sized materials transported along with the belt conveyor 1 and make them be impacted and crushed into small pieces, and the small pieces of materials will then continue to be conveyed through the gaps between the baffle teeth 6.

[0023] The lead screw 3 is installed on the I-beam cross beam 2, and the lifting adjustment of the T-shaped baffle 4 is realized through rotational motion. The lead screw 3 is made of high-strength steel, has an accurate pitch and good wear resistance. One end of the lead screw 3 is connected with a manual operation mechanism. By controlling the rotation of the lead screw 3, the height of the T-shaped baffle 4 can be adjusted to adapt to large-sized materials of different sizes.

[0024] The T-shaped baffle 4 is installed below the lead screw 3, and the distance between it and the belt conveyor 1 is controlled by adjusting the lifting of the lead screw 3. The T-shaped baffle 4 is usually made of high-strength wear-resistant materials and has good impact resistance and wear resistance. The shape and size of the T-shaped baffle 4 are designed according to the width of the belt conveyor 1 and the working requirements to ensure that it can effectively block large pieces of materials.

[0025] In some embodiments, it further includes a baffle 5 which is vertically arranged at the bottom of the cross beam 2 and is arranged closely against the flange plate of the T-shaped baffle 4. The baffle 5 can disperse the pressure of large pieces of materials on the lead screw 3 and protect the safe use of the lead screw 3.

[0026] In some embodiments, the included angle between the extending direction of the I-beam cross beam 2 and the extending direction of the belt conveyor 1 is an acute angle; on the side of the belt conveyor 1, on the side close to the baffle tooth 6 which is farthest from the feeding direction of the belt conveyor 1, there are two receiving inclined plates 8 which are respectively located on both sides of the baffle tooth 6 along the feeding direction. The receiving inclined plates 8 are made of wear-resistant steel plates and are arranged obliquely downward, and can be set to 45 degrees, which are used to lead out the splashing materials generated when the baffle tooth 6 crushes materials, so as to prevent damage to the equipment and structures below the belt conveyor 1.

[0027] The purpose of setting the included angle between the extending direction of the I-beam cross beam 2 and the extending direction of the belt conveyor 1 as an acute angle is to make the materials contact the baffle teeth 6 one by one during the traveling process, so that the materials that may fall are guided and pushed onto the receiving inclined plates 8.

[0028] In some embodiments, it further includes two force-bearing piers 10. The force-bearing piers 10 serve as the basic support part of the whole device and bear the weight of the device and various forces generated during operation. It ensures the stability of the device through a firm connection with the ground. The ground force-bearing piers are made of high-strength concrete and steel and have the ability to bear forces.

[0029] On one of the force-bearing piers 10, there is a longitudinal beam 9 vertically arranged. The longitudinal beam 9 is vertically installed on the ground force-bearing pier 10 and plays a main supporting role. Its I-shaped structure provides high strength and stiffness and can bear the pressure and lateral forces from above. The top end of the longitudinal beam 9 is connected to the cross beam 2.

[0030] On the other force-bearing pier 10, there is an inclined beam 11 obliquely arranged. The end of the inclined beam 11 is connected to the top end of the longitudinal beam 9. The inclined beam 11 is obliquely installed between the cross beam 2 and the force-bearing pier 10 and plays a role in strengthening the structural stability. The inclined angle of the inclined beam 11 with the horizontal plane is 45 degrees, which can effectively disperse the forces generated during the operation of the device and improve the anti-deformation ability of the whole device.

[0031] In some embodiments, at least two fixing blocks 12 are arranged at intervals at the connection between the baffle 5 and the cross beam 2. It is used to make the connection between the baffle 5 and the cross beam 2 more stable.

[0032] The usage method of a large-piece material crushing and removing device applicable to a belt conveyor for ironmaking in the present invention is as follows:

[0033] When using a large-piece material crushing and removing device applicable to a belt conveyor for ironmaking in the present invention, it is first necessary to ensure that the device is firmly installed. Firmly connect the ground stress pier 10 to the ground, fix the I-shaped longitudinal beam 9 by means of anchor bolts and welding, and then install the I-shaped inclined beam 11 and the I-shaped cross beam 2 in place by using high-strength seamless welding, so that the whole device forms a stable frame structure. Install the lead screw 3, the T-shaped baffle 4 and the receiving inclined plate 8, and ensure that the connections of all components are normal.

[0034] When the belt conveyor 1 starts to transport materials, the device begins to work. If there are large-piece materials on the belt conveyor 1, as the materials move, the large-piece materials will come into contact with the T-shaped baffle 4 and the baffle teeth 6. At this time, the baffle teeth 6 will block the large-piece materials from moving forward. Since the continuously transported materials will generate an impact force on the baffle teeth 6, the large-piece materials will be broken, and the materials that fall due to the breaking will slide down from the receiving inclined plate 8 on one side. Since the receiving inclined plate 8 and the belt conveyor 1 have a downward inclination angle, under the action of gravity, the materials will slide downward along the receiving inclined plate 8 to the side of the belt conveyor 1, thus completing a process of removing large-piece materials.

[0035] In the actual use process, the height of the T-shaped baffle 4 can also be adjusted by manually operating the lead screw 3 according to the size of the large-piece materials to meet different working requirements, so as to ensure that the device can always efficiently handle the large-piece materials on the belt conveyor 1.

[0036] The large-piece material crushing and removing device of the present invention has many remarkable beneficial effects. In terms of production efficiency, the device realizes the automatic processing of large-piece materials without frequent manual intervention. In the past, the manual inspection method was inefficient, consumed a large amount of manpower and time, and it was also difficult to ensure the timely discovery and processing of all large-piece materials. However, this device can work continuously for 24 hours, greatly saving time and labor costs, ensuring the continuity of production, and enabling the sintering production to proceed efficiently and stably.

[0037] From the perspective of production cost, due to the high processing capacity of the device, the production failures caused by large-piece materials are reduced, and the equipment maintenance cost and production stoppage losses are lowered. At the same time, the quality problems of sintered ore are also reduced, and the waste caused by unqualified quality is avoided, thus indirectly reducing the production cost and creating greater economic benefits for the enterprise.

[0038] In terms of fabric quality, by effectively crushing and removing large pieces of material on the belt conveyor 1, the phenomenon of uneven fabric caused by large pieces of material is avoided. Uniform fabric provides a solid technical guarantee for stable and high-quality sintering, improves the quality of sintered ore, makes the quality of the finally produced steel products better, and enhances the competitiveness of the products in the market.

[0039] The device of the present invention breaks through the disadvantages of low efficiency of manual inspection and the simple mechanical device that can only block large pieces of material but cannot remove them, realizes the automatic processing of large pieces of material, improves production efficiency and stability, and reduces production costs. At the same time, the device is innovative in the way of crushing and removing large pieces of material, ensuring the stable and high-quality progress of the sintering fabric process.
