Description

Technical Field

[0001] The utility model belongs to the technical field of steel metallurgical equipment, in particular to a material guide box buffer device for a single-roll crusher. Background Art

[0002] During the sintering process, the sintered ore that has been burned at high temperature in the ignition furnace of the sintering machine is in block shape, and its size is usually measured in meters, such as 3m*1.5m*1m. In addition, the sintered ore is relatively heavy, usually around 10t. Such large and heavy sintered ore is transported to the single-roll crusher by a trolley. Due to its large size, there is a certain height difference between the trolley and the single-roll crusher, and this height difference is usually greater than 3m.

[0003] like Figure 1 As shown, when the sintered ore 20 falls from the trolley 10 (i.e., the slide) under transportation, it will fall onto the inclined surface of the buffer device 30, and then roll towards the single-roll crusher 40 for crushing. The small-sized sintered ore after crushing is sent to the subsequent ironmaking process.

[0004] The commonly used buffer device 30 has a cast base at its bottom, with a large, thick steel plate installed above it. However, in actual production, due to the large weight and volume of sintered ore and the high frequency of trolley transportation (a large lump of sintered ore is transported every 20 to 30 seconds), the commonly used steel plate buffer device is easily bent, causing sintered ore to accumulate in the feed box. In severe cases, it can cause accidental shutdowns, hindering continued production. Utility Model Content

[0005] The utility model aims to provide a single roller crusher material guide box buffer device to reduce the accumulation of sintered ore in the material guide box and avoid affecting normal production.

[0006] The utility model adopts the following technical solution: a single roller crusher guide box buffer device, comprising a base, a vertical plate vertically arranged on the base, the length direction of the vertical plate being the same as the length direction of the sintered ore dropped from the trolley;

[0007] Several front ribs are provided on the front side of the vertical plate, and the sides of the front ribs facing the single roller crusher are beveled;

[0008] The two adjacent front ribs are spaced apart and form an overflow trough with the vertical plate. The overflow trough is used to accommodate the crushed sintered ore and reduce the force applied to the front rib when the sintered ore falls.

[0009] Furthermore, a front baffle is provided at the front end of the overflow trough.

[0010] Furthermore, a scraper plate is provided above the vertical plate, and there are two scraper plates which are arranged parallel to each other in the front and rear directions.

[0011] Furthermore, a plurality of rear ribs are provided on the rear side of the vertical plate.

[0012] Furthermore, a rear stop plate is provided at the bottom of the rear rib plate.

[0013] Furthermore, the distance between the front ribs at the two end portions and the adjacent front ribs is equal to the distance between two other adjacent front ribs.

[0014] Furthermore, a bottom plate is provided between the base and the vertical plate.

[0015] Furthermore, mounting holes are provided on the front ribs on both sides and the adjacent front ribs.

[0016] The beneficial effects of the present invention are as follows: the present invention forms an overflow trough through the vertical plate and the front rib plate, and the overflow trough can accommodate broken sintered slag. When large pieces of sintered ore fall, the slag can be used to cushion the impact force on the vertical plate and the front rib plate, thereby reducing the chance of damage, extending the maintenance cycle, and improving production efficiency.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The utility model discloses a single roller crusher guide box buffer device, such as Figure 2 and Figure 3As shown, it includes a base 55, and a vertical plate 56 is vertically arranged on the base 55. The length direction of the vertical plate 56 is the same as the length direction of the sintered ore 20 dropped from the trolley 10; a plurality of front ribs 51 are arranged on the front side of the vertical plate 56, and the edge of the front rib 51 facing the single-roll crusher 40 is a beveled edge; two adjacent front ribs 51 are arranged at intervals, and form an overflow trough with the vertical plate 56, and the overflow trough is used to accommodate the crushed sintered ore 20 and reduce the force on the front rib 51 when the sintered ore 20 falls.

[0024] The utility model forms an overflow trough by the vertical plate 56 and the front rib plate 51, and the overflow trough can accommodate broken sintered slag. When large pieces of sintered ore fall, the slag can buffer the impact force on the vertical plate 56 and the front rib plate 51, thereby reducing the chance of damage, extending the maintenance cycle, and improving production efficiency.

[0025] In this embodiment, a front baffle plate 53 is provided at the front end of the overflow trough, which can block small pieces of sintered slag in the overflow trough to prevent the small pieces of sintered slag from overflowing, thereby ensuring that there is sufficient slag in the overflow trough.

[0026] A scraper 52 is provided above the vertical plate 56. There are two scraper plates 52 and they are arranged parallel to each other. Specifically, the top edge of the scraper plate 52 is a flat edge. Since the running track of the trolley 10 is similar to a conveyor belt, Figure 1 As shown, after its unloading, can return and continue to connect materials again.The residual slag material on the trolley 10 planes can be cleaned by scraper plate 52.

[0027] In order to increase the strength of the buffer device, the rear side of the vertical plate is provided with several rear ribs 58. More specifically, the bottom of the rear rib 58 is provided with a rear baffle 54. The rear baffle 54 can prevent the material from being mistakenly fed into the rear side of the guide box.

[0028] In one embodiment, the spacing between the front ribs 51 at both ends and the adjacent front ribs 51 is equal to the spacing between any two adjacent front ribs 51. Mounting holes are provided on the front ribs 51 on both sides and the adjacent front ribs 51. These mounting holes allow for the installation of lifting components, making it easier to lift the entire buffer device using a power mechanism, facilitating installation and maintenance.

[0029] In addition, a bottom plate 57 is provided between the base 55 and the vertical plate 56. The design of the bottom plate 57 divides the buffer device into two parts, the base 55 at the bottom and the buffer structure at the top. This prevents the sintered ore 20 from impacting the base 55 at the bottom and facilitates repairs if the buffer structure at the top is damaged.

[0030] In summary, the sintered ore 20 is transported to the tail of the trolley 10 and dropped to the inside of the material guide box, and then enters the single-roll crusher 40 through the overflow trough (buffer device). In order to increase the wear resistance of the overflow trough and reduce the impact force of the falling material, a design scheme is adopted in which a scraper block is installed on the upper part of the chute and a stop block is installed on the lower part. The sintered ore 20 falls into the single-roll crusher under the action of gravity for crushing.

[0031] This new buffer device effectively reduces the impact of falling material, mitigates equipment hazards, meets operational requirements, and improves production continuity. Its implementation is simple and convenient, with low modification costs and strong practicality. It can be used to reduce deformation of the slide support of a single-roll crusher caused by the impact of falling sintered ore, thereby preventing unexpected downtime.
