Abstract
Description
A bottom-mounted square box chute for transferring return ore materials Technical Field
[0001] This utility model relates to the field of metallurgical technology, specifically a bottom-loading square box chute for transferring return ore materials. Background Technology
[0002] In the steel industry, efficient and low-cost production processes have always been a key objective. Full utilization of resources is crucial for maintaining the sustainable development of the steel industry, and the efficient handling and transportation of recycled ore, as a key recyclable resource, is a vital link in improving production efficiency.
[0003] In the production process of the ironmaking workshop, return ore needs to flow from the silo and be transferred to the conveyor belt of the conveyor. Traditionally, this is done using a vibrating feeder. However, return ore is highly abrasive, making the vibrating feeder components easily damaged during frequent use, and repairing such damage is difficult. Furthermore, the vibrating feeder requires a vibrating motor, which consumes a large amount of electricity, resulting in high production costs. Therefore, a bottom-mounted square box chute for transferring return ore is proposed. Summary of the Invention
[0004] The present invention aims to solve the above problems and thus provide a bottom-filling square box chute for transferring return ore materials.
[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:
[0006] A bottom-mounted square box chute for transferring return ore materials includes a square box installed below the discharge port of a silo with an open top. One side of the square box is inclined downwards with a chute communicating with the interior of the box. The discharge end of the chute is located above the conveyor belt of a conveyor. The bottom of the square box forms a storage trough for storing materials. The lowest point of the connection between the square box and the chute is higher than the bottom surface of the square box. Material falls from the silo into the square box. Initially, the material stays in the storage trough. As more material falls in, it forms an accumulation angle within the square box. Subsequent material slides down along this accumulation angle and is transferred to the conveyor belt of the conveyor via the chute. The accumulation angle forms a wear-resistant layer at the bottom of the square box, reducing direct impact and wear on the box and increasing its service life.
[0007] Furthermore, the discharge port of the inclined chute has a vertical cross-section, and a discharge valve plate is hinged to the top of the discharge port. A discharge valve plate cylinder is hinged to the back of the discharge valve plate. The discharge valve plate cylinder is fixed to the outer wall of the inclined chute through a support frame, and the discharge valve plate cylinder and the support frame are rotatably connected. This allows for control of the discharge of the inclined chute, adjustment of the material flow rate according to production needs, and flexible control of the material transfer process.
[0008] Furthermore, a reinforcing plate is installed inside the square box and on the side wall below the connection between the square box and the inclined chute; this enhances the structural strength of the square box in key material flow areas, effectively resists the impact force brought by material flow, and improves the overall stability and durability of the square box.
[0009] Furthermore, multiple wear-resistant baffles are spaced apart on the lower inner wall of the inclined chute; these baffles provide a certain buffer for the material flow, and some material will get stuck above the wear-resistant baffles, forming a wear-resistant layer on the bottom surface of the inclined chute, thus reducing the wear of the inclined chute.
[0010] Furthermore, wear-resistant liners are installed on the bottom and inner side walls of the inclined chute; this increases the wear resistance of the parts of the inclined chute that come into contact with the material, reduces the degree of wear on the inclined chute by the material, ensures the long-term stable operation of the inclined chute, and reduces equipment maintenance costs.
[0011] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:
[0012] This invention features a square box with an open top to receive materials flowing from the hopper. The materials accumulate at the bottom of the box in a storage trough, allowing subsequent materials to slide down along this accumulation angle and be transferred to the conveyor belt via an inclined chute. The accumulation angle forms a wear-resistant layer at the bottom of the box, reducing direct impact and wear on the chute. Compared to traditional vibrating feeders, this design reduces the risk of component damage and extends the equipment's lifespan. Furthermore, it eliminates the need for a vibrating motor, reducing energy consumption and thus lowering production costs. Attached Figure Description

[0015] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.
[0016] Referring to Figure 1, a bottom-mounted square box chute for transferring return ore materials includes a square box 1 installed below the discharge port of the silo 8 with an open top. An inclined chute 2, communicating with the interior of the square box 1, is inclined downwards on one side. The discharge end of the inclined chute 2 is located above the conveyor belt of the conveyor 9. A storage trough for storing materials is formed at the bottom of the square box 1. The lowest point of the connection between the square box 1 and the inclined chute 2 is higher than the bottom surface of the square box 1. Material falls from the silo 8 into the square box 1. Initially, the material stays in the storage trough. As more material falls in, it forms an accumulation angle within the square box 1. Subsequent material slides down along this accumulation angle and is transferred to the conveyor belt of the conveyor 9 via the inclined chute 2. The accumulation angle forms a wear-resistant layer at the bottom of the square box 1, reducing direct impact and wear on the square box 1 and increasing its service life.
[0017] The discharge port of the inclined chute 2 has a vertical cross-section. A discharge valve plate 7 is hinged to the top of the discharge port of the inclined chute 2, and a discharge valve plate cylinder 4 is hinged to the back of the discharge valve plate 7. The discharge valve plate cylinder 4 is fixed to the outer wall of the inclined chute 2 through a support frame 5. The discharge valve plate cylinder 4 and the support frame 5 are rotatably connected. It can control the discharge of the inclined chute 2, adjust the material flow according to production needs, and realize flexible control of the material transfer process.
[0018] A reinforcing plate 6 is provided inside the square box 1 and on the side wall below the connection between the square box 1 and the inclined chute 2; this enhances the structural strength of the square box 1 at key parts of material flow, effectively resists the impact force brought by material flow, and improves the overall stability and durability of the square box 1.
[0019] Multiple wear-resistant baffles 3 are spaced apart on the lower inner wall of the inclined chute 2; these baffles provide a certain buffer for the material flow. At the same time, some material will get stuck above the wear-resistant baffles 3, forming a wear-resistant layer on the bottom surface of the inclined chute 2, thus reducing the wear of the inclined chute 2.
[0020] Wear-resistant liners are installed on the bottom and inner side walls of the inclined chute 2; this increases the wear resistance of the parts of the inclined chute 2 that come into contact with the material, reduces the degree of wear on the inclined chute 2 by the material, ensures the long-term stable operation of the inclined chute 2, and reduces equipment maintenance costs.
[0021] This invention features a square box with an open top to receive materials flowing from the hopper. The materials accumulate at the bottom of the box in a storage trough, allowing subsequent materials to slide down along this accumulation angle and be transferred to the conveyor belt via an inclined chute. The accumulation angle forms a wear-resistant layer at the bottom of the box, reducing direct impact and wear on the chute. Compared to traditional vibrating feeders, this design reduces the risk of component damage and extends the equipment's lifespan. Furthermore, it eliminates the need for a vibrating motor, reducing energy consumption and thus lowering production costs.
