Description

Technical Field

[0001] This utility model belongs to the field of material control, and specifically relates to an adjustment device that can uniformly control materials. Background Technology

[0002] Sintered ore entering the blast furnace for smelting must be screened by a screening system. Sintered ore that passes the screening is conveyed into the blast furnace, while undersized ore is returned to the ore yard. The content of fine particles smaller than 5mm in the sinter entering the blast furnace must be controlled within a specified range. Lower content of fine particles smaller than 5mm is beneficial for improving the permeability of the feed column, stabilizing furnace operation, saving coke, and increasing iron production. However, when the material is discharged from the feeder and screened by a vibrating screen, the quantity is difficult to control, and the screening time is short and uneven, resulting in uneven material passing through the screen and substandard powder entering the furnace.

[0003] In view of this, in order to solve the above problems, this utility model proposes an adjustment device that can ensure the uniform sieving of the materials required for the blast furnace, improve the sieving efficiency, and ensure that the powder entering the furnace (≤5mm portion) is ≤2%. This device is convenient and quick to operate, saves time and effort, and avoids the safety risks brought about by traditional adjustment methods. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] See Figure 1A regulating device for uniformly controlling materials includes a feeder 1. A mounting plate 2 is horizontally mounted at the outlet of the feeder 1. A vibrating screen 4 is connected downwardly via a hanging support frame 3 directly below the mounting plate 2. A vibrating motor 5 is fixedly mounted on the lower surface of the vibrating screen 4, which is powered by an external power supply. Slide grooves 6 are vertically upward on opposite sides of the vibrating screen 4, and a sliding plate 7 is slidably mounted between the two slide grooves 6. A gantry frame 8 is mounted above the mounting plate 2. An adjusting screw 9 is vertically upward mounted on one side of the sliding plate 7. The upper end of the adjusting screw 9 moves through the mounting plate 2 and the gantry frame 8. An adjusting handle 11 is fitted on the adjusting screw between the mounting plate 2 and the gantry frame 8, which allows the adjusting screw 9 to rise or fall. The adjusting handle 11 has an internal thread that matches the adjusting screw 9. By rotating the adjusting handle, the internal threads on both the upper and lower sides of the adjusting handle 11 that match the adjusting screw 9 can be achieved.

[0015] Preferably, two sliding grooves 6 are respectively set on the outer side of the vibrating screen 4, and the slide plate 7 is set between the two side walls of the vibrating screen 4. Long strip sliders are slidably installed in the two sliding grooves 6 respectively. The two long strip sliders are fixedly connected to the two sides of the slide plate 7 by connecting blocks. Setting the two sliding grooves 6 on the outer side of the vibrating screen 4 can avoid the sliding grooves 6 from being blocked by materials.

[0016] The preferred gantry frame 8 has thrust bearings 10 on its lower side and mounting plate 2 on its upper side, through which the adjusting screw 9 can pass. The two thrust bearings 10 are arranged radially, and their seats are fixedly connected to the lower side of the gantry frame 8 and the upper side of the mounting plate 2, respectively. The adjusting handle is set on the adjusting screw 9 between the two thrust bearings 10, and its upper and lower ends abut against the two thrust bearings 10, respectively. The arrangement of the two thrust bearings 10 not only makes it easier to rotate the adjusting handle 11, but also serves to position the adjusting screw 9.

[0017] The two chutes 6 are preferably located in the middle of the outer side of the vibrating screen 4 to ensure that the material can be fully screened after passing through the slide plate 7.

[0018] A connecting seat 12 is preferably fixed to the slide plate 7 on the side of the vibrating screen 4, and the adjusting screw 9 is detachably connected to the connecting seat 12 through a shaft pin.

[0019] A protective cover 13 is detachably connected to the upper side of the preferred gantry frame 8 via bolts, which covers the outer surface of the adjusting screw 9. The protective cover 13 can prevent debris from falling into the hole of the gantry frame 8.

[0020] The working principle of this utility model is as follows: First, when the material falls from the feeder to the vibrating screen, is screened, and continues to be conveyed downwards, the adjusting handle 11 is manually rotated. The adjusting handle 11 has internal threads on both the upper and lower sides that match the adjusting screw 9. When the adjusting handle 11 is rotated, the adjusting screw 9 can be pulled up or down. At this time, the slide plate 7 will rise or fall along the slide groove 6. By adjusting, the distance between the slide plate 7 and the upper surface of the vibrating screen 4 can be limited, thereby ensuring that the material can pass through the slide plate 7 quantitatively, so that the material can be screened evenly. This not only improves the screening efficiency, but also ensures that the powder entering the furnace is (≤5mm portion) ≤2%.

[0021] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
