Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste steel material transfer facilities, and relates to a waste steel transfer buffer chute. Background Technology
[0002] With the rapid development of the steel industry, scrap steel, as a recyclable resource, plays an increasingly important role in steel production. Scrap steel not only saves natural resources and energy but also reduces emissions of wastewater, waste gas, and waste residue, which is of great significance for achieving green and low-carbon development. However, the problems existing in the transportation of scrap steel cannot be ignored.
[0003] In traditional scrap steel transfer chutes, the high speed at which scrap steel slides down from upstream to downstream conveyor equipment causes frequent impacts, easily scratching and puncturing the equipment, increasing maintenance costs. Furthermore, the sharp edges and high abrasiveness of scrap steel exacerbate this problem. Therefore, effectively reducing the impact of scrap steel on downstream conveyor equipment and extending its service life has become an urgent issue to be addressed.
[0004] Currently, although some improvement measures have been implemented, such as adding buffer devices and optimizing chute structures, these methods still have certain limitations, such as poor buffering effect, complex structure, and high cost. Therefore, developing a scrap steel transfer buffer chute with a simple structure, stable operation, and flexible process layout to reduce the impact of scrap steel on downstream conveying equipment and extend the service life of the equipment has become a research focus for those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a scrap steel transfer buffer chute, which aims to reduce the impact of scrap steel on downstream conveying equipment, extend the service life of the equipment, and has the characteristics of simple structure, stable operation and flexible process layout.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A scrap steel transfer buffer chute, comprising:
[0008] The first-stage chute consists of a tail side baffle, two side baffles and a bottom plate, and is used to receive scrap steel material conveyed by the upstream conveying equipment.
[0009] At least one second-stage chute is formed by two side baffles and a bottom plate. The second-stage chute overlaps with the first-stage chute by a certain distance, and the angle between the first-stage chute and the downstream conveying equipment is greater than the angle between the second-stage chute and the downstream conveying equipment.
[0010] A spring vibration device includes a spring mounting base, a spring, and a vibration motor. The spring mounting base is fixed to the side baffles or bottom plate of the first or second chute. One end of the spring is connected to the spring mounting base, and the other end is fixed to the mounting frame. The vibration motor is mounted on the side baffles or bottom plate of the first or second chute.
[0011] Optionally, the overlapping portion of the first-stage chute and the second-stage chute is connected by the extension structure of the side baffles and the bottom plate to ensure that the material does not spill when sliding from the upper chute to the lower chute.
[0012] Optionally, the vibration motor of the spring vibration device is configured to start when the chute angle is less than a set threshold, so as to prevent material blockage through vibration.
[0013] Optionally, the mounting bracket is fixed to the ground or an adjacent equipment base by bolts or welding, and the first and second chutes are elastically connected to the mounting bracket by springs to buffer material impact.
[0014] Optionally, the height of the tail baffle is higher than that of the side baffles, forming a guide structure to constrain the material's sliding path.
[0015] Optionally, the bottom plate surface of each chute is covered with a wear-resistant liner to reduce the abrasion effect of scrap steel.
[0016] Optionally, the installation position of the vibration motor can be dynamically adjusted according to the chute angle and material flow rate to optimize the vibration anti-clogging effect.
[0017] Optionally, the angle decreasing configuration is as follows: the angle between the first-stage chute and the downstream conveying equipment is α, the angle of the second-stage chute is β, and α>β is satisfied. The angles of subsequent stages decrease sequentially until the difference between the angle of the last-stage chute and the angle of the downstream conveying equipment does not exceed 5°.
[0018] Optionally, a mounting bracket may also be included for fixing and supporting the first-stage chute, the second-stage chute, and the spring vibration device.
[0019] Optionally, the second-stage chute can be set to two or more stages according to engineering requirements, and the angle between each two adjacent stages decreases, so that the angle of the last stage chute matches that of the downstream conveying equipment.
[0020] The beneficial effects of this utility model are as follows:
[0021] Reduce the angle at which scrap steel cuts into downstream conveying equipment: By setting up multi-stage chutes, the angle of the last chute is made as close as possible to the angle of the downstream conveying equipment, thereby reducing the impact of scrap steel on the downstream equipment.
[0022] Slow down the speed at which scrap steel falls into downstream conveying equipment: By gradually reducing the angle setting, the speed of scrap steel as it falls into downstream conveying equipment is slowed down, further reducing the impact on the equipment.
[0023] Reduce wear caused by scrap steel: By designing buffer chutes, wear on downstream conveying equipment caused by scrap steel is reduced, extending the service life of the equipment.
[0024] Reduce the impact of scrap steel on downstream conveying equipment: By setting up a spring vibration device, the chute vibrates when the chute angle is small, avoiding the risk of material blockage, and at the same time reducing the impact of scrap steel on downstream conveying equipment.
[0025] Extending equipment lifespan: The above design reduces the wear and impact of scrap steel on downstream conveying equipment, thereby extending the equipment's lifespan.
[0026] Simple structure, stable operation, and flexible process layout: The scrap steel transfer buffer chute designed in this scheme has the characteristics of simple structure, stable operation, and flexible process layout, which is convenient for practical application and promotion.

[0048] Please see Figures 1-5 This is a scrap steel transfer buffer chute, consisting of a first-stage chute 1, a second-stage chute 2, a spring vibration device 3, and a mounting frame 4. The spring vibration device 3 includes a spring mounting base 301, a spring 302, and a vibration motor 303. The second-stage chute 2 can be configured as a two-stage or multi-stage chute according to actual needs. When arranging the first-stage chute 1 and the second-stage chute 2, the upper and lower stages need to overlap by a certain distance to ensure sufficient overlap between the two stages, allowing scrap steel to smoothly slide from the upper stage to the lower stage and preventing material spillage at the connection point. The angle between each stage of the scrap steel transfer buffer chute and the downstream conveying equipment decreases progressively; that is, the angle between the first-stage chute 1 and the downstream conveying equipment is greater than the angle between the second-stage chute 2 and the downstream conveying equipment, the angle between the second-stage chute 2 and the downstream conveying equipment is greater than the angle between the third stage chute, and so on, so that the angle of the last stage chute is as close as possible to the angle of the downstream conveying equipment. Figure 1 , Figure 2 and Figure 3 As shown in the diagram, this configuration effectively reduces the angle at which scrap steel cuts into the downstream conveying equipment, slows down the speed at which the scrap steel falls into the downstream conveying equipment, thereby reducing the impact of the scrap steel on the chute and the downstream conveying equipment, and extending the service life of the equipment.
[0049] The first-stage chute 1 is composed of a tail side baffle 101, two side baffles 102, and a bottom plate 103. Optionally, the first-stage chute 1 may be equipped with a spring mounting seat 301, a spring 302, and a vibration motor 303. Figure 4 As shown. When the scrap steel transfer volume is large and the speed is fast, the first-stage chute 1 can be equipped with a spring mounting seat 301 and a spring 302 to reduce the impact of scrap steel on the chute. In this case, the first-stage chute 1 and the spring mounting seat 301 are installed together on the spring 302, and the spring 302 is fixed on the mounting frame 4. The spring mounting seat 301 can be installed on the side baffles 102 or the bottom plate 103 according to actual needs. If the first-stage chute 1 is not equipped with a spring mounting seat 301 and a spring 302, the first-stage chute 1 is directly installed on the mounting frame 4. When the angle of the first-stage chute 1 can ensure that the scrap steel slides smoothly to the next stage chute, the vibration motor 303 does not need to be installed; otherwise, the vibration motor 303 needs to be installed to prevent material blockage. The vibration motor 303 can be installed on the side baffles 102 or the bottom plate 103 according to actual needs.
[0050] The second-stage chute 2 is composed of two side baffles 102 and a bottom plate 103. Optionally, the second-stage chute 2 may be equipped with a spring mounting base 301, a spring 302, and a vibration motor 303. Figure 5As shown. If the scrap steel transfer buffer chute has only two chute stages, then the second chute 2 needs to be equipped with a spring mounting base 301, a spring 302, and a vibration motor 303. If a multi-stage chute is set up, the setting method of the spring mounting base 301, spring 302, and vibration motor 303 in the middle stage chute is basically the same as the setting principle and installation method of the first stage chute 1. The last stage of the multi-stage scrap steel transfer buffer chute also needs to be equipped with a spring mounting base 301, spring 302, and vibration motor 303 to reduce the angle at which the scrap steel cuts into the downstream conveying equipment, slow down the speed at which the scrap steel falls into the downstream conveying equipment, thereby reducing the wear and impact of the scrap steel on the downstream conveying equipment and extending the service life of the equipment.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
