Description

[Technical Field]

[0001] This utility model belongs to the field of mine material transportation technology, specifically relating to a crushing and removal device for large materials suitable for belt conveyors used in ironmaking. [Background Technology]

[0002] In the pre-sintering stage of steel production, the quality of the sintering feed has a crucial impact on the final steel product quality. Currently, the feeding method using a widened oscillating belt conveyor with eleven rollers is widely used in ironmaking sintering. The mixed-four-belt conveyor, as the final process equipment entering the feeding system after batching, mixing, and pelletizing, directly affects the quality of the sintering feed. However, in actual production, due to the complexity of raw material procurement, storage, and transportation, large pieces of material often appear on the mixed-four-belt conveyor.

[0003] Traditional processing methods mainly include manual inspection and the use of simple mechanical devices. Manual inspection relies on the experience and responsibility of operators, which is inefficient and makes it difficult to ensure the timely detection and handling of all large pieces of material. In the ironmaking sintering production environment, it cannot meet the requirements of high-efficiency production and is prone to production interruptions and unstable quality. Simple mechanical devices, such as grates, can prevent some large pieces of material from entering the feeding system, but they cannot crush or remove them, and the accumulated material will still affect normal production. [Utility Model Content]

[0004] The purpose of this invention is to provide a large material crushing and removal device suitable for belt conveyors used in ironmaking, in order to solve the problem that large materials cannot be crushed and removed from existing belt conveyors, thus affecting normal production.

[0005] This utility model adopts the following technical solution: a large material crushing and removal device suitable for ironmaking belt conveyors, including an I-beam horizontally arranged above the belt conveyor, the angle between the extension direction of the I-beam and the extension direction of the belt conveyor being an acute angle; a T-shaped baffle is provided at the bottom of the beam, the web of the T-shaped baffle being horizontally arranged; two screws are vertically arranged and spaced apart, passing through the upper and lower flanges of the beam, and two nuts threaded to the two screws are fixedly arranged on the upper flange; the lower end of each screw passes through the flange and connects to the web of the T-shaped baffle; at least three baffle teeth are spaced apart on the web, each baffle tooth being a vertically arranged plate structure;

[0006] The lead screw is used to move the T-shaped baffle up and down by lifting and lowering it; the baffle teeth are used to block large pieces of material that are being transported by the belt conveyor and crush them into smaller pieces by impact force so that they can continue to be transported.

[0007] Furthermore, it also includes a baffle that is vertically set at the bottom of the crossbeam and arranged close to the flange of the T-shaped baffle.

[0008] Furthermore, the angle between the extension direction of the I-beam and the extension direction of the belt conveyor is an acute angle; two receiving inclined plates are provided on the side of the belt conveyor, near the side of the baffle tooth furthest from the feed direction of the belt conveyor, located on both sides of the baffle tooth along the feed direction; the receiving inclined plates are inclined downwards to discharge the splashed material generated when the baffle tooth crushes the material.

[0009] Furthermore, it also includes two load-bearing piers. One load-bearing pier has a vertically installed longitudinal beam, the top of which is connected to a crossbeam. The other load-bearing pier has an inclined beam, the end of which is connected to the top of the longitudinal beam.

[0010] Furthermore, at least two fixing blocks are spaced apart at the connection between the baffle and the crossbeam.

[0011] The beneficial effects of this invention are as follows: The large material crushing and removal device of this invention has many significant advantages. In terms of production efficiency, the device achieves automated processing of large materials without frequent manual intervention. Previously, manual inspection methods were inefficient, consuming a large amount of manpower and time, and it was difficult to ensure the timely detection and handling of all large materials. This device, however, can work 24 hours a day without interruption, greatly saving time and labor costs, ensuring the continuity of production, and allowing sintering production to proceed efficiently and stably.

[0012] From a production cost perspective, the device's high processing capacity reduces production failures caused by large pieces of material, lowering equipment maintenance costs and downtime losses. Simultaneously, it reduces sinter quality issues, avoiding waste due to substandard quality, thereby indirectly lowering production costs and creating greater economic benefits for the company.

[0013] Regarding the quality of the material distribution, large pieces of material on conveyor belt 1 are effectively crushed and removed, preventing uneven distribution caused by these large pieces. Uniform material distribution provides a solid technical guarantee for stable and high-quality sintering, improves the quality of the sintered ore, and results in higher quality steel products, enhancing their competitiveness in the market.

[0014] This invention overcomes the shortcomings of low efficiency in manual inspections and the limitations of simple mechanical devices that can only block large pieces of material without removing them. It achieves automated processing of large pieces of material, improving production efficiency and stability while reducing production costs. Furthermore, the device is innovative in its method of crushing and removing large pieces of material, ensuring a stable and high-quality sintering and feeding process. [Attached Image Description]

Detailed Implementation Methods

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] This utility model provides a device for crushing and removing large pieces of material suitable for belt conveyors used in ironmaking, such as... Figure 1 As shown, it includes an I-beam beam 2 horizontally positioned above the belt conveyor 1, serving as the main working platform of the device. Its I-beam structure provides a large load-bearing area and strength, enabling the installation and support of other components. The length of the I-beam beam 2 is designed according to the width of the belt conveyor 1, ensuring it covers the entire width of the belt conveyor 1 and effectively handles large pieces of material.

[0020] like Figure 2 As shown, a T-shaped baffle 4 is provided at the bottom of the crossbeam 2, and the web plate 401 of the T-shaped baffle 4 is horizontally arranged; two lead screws 3 are arranged vertically and at intervals through the upper and lower flange plates 201 of the crossbeam 2, and two nuts 7 that are threaded to the two lead screws 3 are fixedly arranged on the upper flange plate 201.

[0021] The lower end of each lead screw 3 extends through the flange plate 201 of the crossbeam 2 and connects 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 and lowering; the baffle teeth 6 are used to block large pieces of material that are transported by the belt conveyor 1 and crush them into small pieces by impact force. The small pieces of material will then continue to be transported through the gap between the baffle teeth 6.

[0023] The lead screw 3 is mounted on the I-beam 2 and adjusts the height of the T-shaped baffle 4 through rotation. The lead screw 3 is made of high-strength steel and has a precise pitch and good wear resistance. One end of the lead screw 3 is connected to a manual operating mechanism. By controlling the rotation of the lead screw 3, the height of the T-shaped baffle 4 can be adjusted to accommodate large pieces of material of different sizes.

[0024] The T-shaped baffle 4 is installed below the lead screw 3, and its distance from the conveyor belt 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 material, with good impact resistance and wear resistance. The shape and size of the T-shaped baffle 4 are designed according to the width of the conveyor belt 1 and the working requirements to ensure that large pieces of material can be effectively blocked.

[0025] In some embodiments, a baffle 5 is further included, which is vertically disposed at the bottom of the crossbeam 2 and arranged close to the flange of the T-shaped baffle 4. The baffle 5 can disperse the pressure of large pieces of material on the lead screw 3, protecting the safe use of the lead screw 3.

[0026] In some embodiments, the angle between the extending direction of the I-beam 2 and the extending direction of the belt conveyor 1 is an acute angle. Two receiving inclined plates 8 are provided on the side of the belt conveyor 1, near the side of the baffle tooth 6 furthest from the feed direction of the belt conveyor 1, located on both sides of the baffle tooth 6 along the feed direction. The receiving inclined plates 8 are made of wear-resistant steel plates and are inclined downwards, possibly at 45 degrees, to discharge splashed material generated when the baffle tooth 6 crushes the material, preventing damage to the equipment and structure below the belt conveyor 1.

[0027] The purpose of setting the angle between the extension direction of the I-beam beam 2 and the extension direction of the belt conveyor 1 to an acute angle is to ensure that the material contacts the baffle teeth 6 one by one during the process of moving, so that the material that may fall off is guided and pushed onto the receiving inclined plate 8.

[0028] In some embodiments, the device further includes two load-bearing blocks 10, which serve as the foundational support for the entire device, bearing the weight of the device and various forces generated during operation. Their secure connection to the ground ensures the stability of the device. The ground load-bearing blocks are made of high-strength concrete and steel, possessing load-bearing capacity.

[0029] One of the load-bearing piers 10 has a vertically installed longitudinal beam 9, which is mounted vertically on the ground load-bearing pier 10 and plays a major supporting role. Its I-shaped structure provides high strength and rigidity, and can withstand pressure and lateral forces from above. The top of the longitudinal beam 9 is connected to the crossbeam 2.

[0030] An inclined beam 11 is installed at an angle on another load-bearing pier 10, with its end connected to the top of the longitudinal beam 9. The inclined beam 11 is installed at an angle between the transverse beam 2 and the load-bearing pier 10, which enhances the structural stability. The angle of inclination of the inclined beam 11 is 45 degrees with the horizontal plane, which can effectively disperse the force generated during the operation of the device and improve the deformation resistance of the entire device.

[0031] In some embodiments, at least two fixing blocks 12 are spaced apart at the connection between the baffle 5 and the crossbeam 2. This is to make the connection between the baffle 5 and the crossbeam 2 more secure.

[0032] The method of using the large material crushing and removal device suitable for belt conveyors used in ironmaking according to this utility model is as follows:

[0033] When using the large material crushing and removal device for ironmaking belt conveyors according to this utility model, the first step is to ensure that the device is installed securely. The ground support pier 10 is firmly connected to the ground, and the I-beam longitudinal beam 9 is fixed using anchor bolts and welding. Then, the I-beam inclined beam 11 and I-beam crossbeam 2 are installed in place using high-strength seamless welding, forming a stable frame structure for the entire device. The lead screw 3, T-shaped baffle 4, and receiving inclined plate 8 are then installed, ensuring that all components are properly connected.

[0034] When belt conveyor 1 starts transporting materials, the device begins to operate. If large pieces of material appear on belt conveyor 1, they will come into contact with the T-shaped baffle 4 and baffle teeth 6 as the material moves. At this time, the baffle teeth 6 will block the large pieces of material from moving forward. As the material is continuously transported forward, it will exert an impact force on the baffle teeth 6, causing the large pieces of material to break. The broken material will fall off the receiving inclined plate 8 on one side and slide down. Since the receiving inclined plate 8 has a downward inclination angle with belt conveyor 1, the material will slide down along the receiving inclined plate 8 to the side of belt conveyor 1 under the action of gravity, thus completing one removal process of large pieces of material.

[0035] In actual use, the height of the T-shaped baffle 4 can be adjusted by manually operating the screw 3 according to the size of the large material to adapt to different working requirements, thereby ensuring that the device can always efficiently handle large materials on the belt conveyor 1.

[0036] This utility model's large material crushing and removal device has several significant advantages. In terms of production efficiency, the device automates the processing of large materials, eliminating the need for frequent manual intervention. Traditional manual inspection methods are inefficient, consuming significant manpower and time, and struggle to ensure the timely detection and handling of all large materials. This device, however, can operate 24 hours a day, greatly saving time and labor costs, ensuring continuous production, and enabling efficient and stable sintering operations.

[0037] From a production cost perspective, the device's high processing capacity reduces production failures caused by large pieces of material, lowering equipment maintenance costs and downtime losses. Simultaneously, it reduces sinter quality issues, avoiding waste due to substandard quality, thereby indirectly lowering production costs and creating greater economic benefits for the company.

[0038] Regarding the quality of the material distribution, large pieces of material on conveyor belt 1 are effectively crushed and removed, preventing uneven distribution caused by these large pieces. Uniform material distribution provides a solid technical guarantee for stable and high-quality sintering, improves the quality of the sintered ore, and results in higher quality steel products, enhancing their competitiveness in the market.

[0039] This invention overcomes the shortcomings of low efficiency in manual inspections and the limitations of simple mechanical devices that can only block large pieces of material without removing them. It achieves automated processing of large pieces of material, improving production efficiency and stability while reducing production costs. Furthermore, the device is innovative in its method of crushing and removing large pieces of material, ensuring a stable and high-quality sintering and feeding process.
