Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a vibratable powder mixing bin. Background Art

[0002] At present, the sintering system of iron-making plants uses miscellaneous ores containing steel slag fine powder, sulfuric acid slag, gravity ash, and nickel ore to reduce raw material costs. The powder mixing bin is used to mix various powdery materials according to a ratio to achieve pre-batching, so as to supply the mixed miscellaneous ores with stable components to the sintering machine and ensure the quality of sintered ore. In the metallurgical industry, the powder mixing bin is a commonly used non-powered storage device, usually configured above the belt scale as a batching preparation bin.

[0003] Most traditional powder mixing bins are inverted conical containers with a large feed inlet and a small discharge outlet. When the falling material flows downward, the reverse pressure gradually increases, but the flow cross-section gradually decreases. Therefore, the friction between the material and the side wall of the bin gradually increases, and it is easy for the material to be extruded into an arch, and the bin blockage is a common problem. When the bin is blocked, it is necessary to dredge the blockage. At present, the main methods for dredging the blockage of the powder mixing bin include: 1. Manually knocking on the bin to dredge it. 2. Using an air cannon to impact the bin. 3. Directly impacting the bin with a mechanical vibrator.

[0004] In summary, the current powder mixing bin is prone to blockage. Dredging the blockage will not only affect the mixing efficiency, but also easily bring certain labor and material operations, thus increasing the mixing cost. Summary of the Invention

A vibrator is fixedly connected to the movable lining plate of one group of movable bin vibration components, and a vibrator through hole is provided on the movable bin wall on the side where this group of movable bin vibration components is located. The vibrator extends out from the vibrator through hole.

[0007] Optionally, the vibratable powder mixing bin further comprises four anti-sticking plates. The anti-sticking plates are triangular in shape, and the four anti-sticking plates are respectively fixedly connected to the four corners at the feeding end of the fixed bin.

Detailed Description of the Preferred Embodiments

[0020] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0021] Such as Figures 1 to 4As shown in the figure, the vibratable powder mixing bin provided by the embodiment of the present invention includes a fixed bin 1, a movable bin 2 and two sets of movable bin vibration assemblies 5. Four support columns 10 are welded at the four corners of the top end of the outer wall of the fixed bin 1. The fixed bin 1 is located above the movable bin 2 and the two are interconnected. The bottom of the fixed bin 1 is inserted into the top of the movable bin 2 and fixedly connected by a plurality of connectors 8. A discharge port partition frame is provided at the feed end of the fixed bin 1. The discharge port partition frame is composed of three first angle steels 3 that are longitudinally parallel to each other. The two ends of the first angle steel 3 are respectively welded to the inner walls of the front and rear sides of the fixed bin 1. Each set of movable bin vibration assemblies 5 includes a movable lining plate 5-1, four lifting lugs 5-2 with through holes in the middle and a pin rod 5-3. The movable lining plate 5-1 is attached to the inner wall of the movable bin 2. Two of the lifting lugs 5-2 are welded to the outer wall of the movable bin 2. Two lifting lug through holes are provided on the movable bin 2. The other two lifting lugs 5-2 are welded to the movable lining plate 5-1 and respectively extend out from the two lifting lug through holes. Two of the lifting lugs 5-2 are located between the other two lifting lugs 5-2. The pin rod 5-3 is inserted through the through holes of the four lifting lugs 5-2. A double-layer cross-shaped diverter 6 is welded between the movable lining plates 5-1 of the two sets of movable bin vibration assemblies 5. A vibrator 7 is fixedly connected to the movable lining plate 5-1 of one set of movable bin vibration assemblies 5. A vibrator through hole 9 is provided on the wall of the movable bin 2 on the side where this set of movable bin vibration assemblies 5 is located. The vibrator 7 extends out from the vibrator through hole 9.

[0022] When the vibratable powder mixing bin provided by the embodiment of the present invention is in use, various powders are dug by a loader and enter the fixed bin 1 from the discharge port, and then fall downward through the discharge port partition frame into the movable bin 2, and then are discharged from the discharge port of the movable bin 2 after passing through the double-layer cross-shaped diverter 6. During the feeding process, the vibrator 7 is turned on and generates vibration. After driving the movable lining plate 5-1 and the double-layer cross-shaped diverter 6 to vibrate together, the powdery materials can pass through smoothly. The double-layer cross-shaped diverter 6 not only plays a role in transmitting vibration, but also plays a role in supporting the materials and compacting the electronic scale belt. The discharge port partition frame is used to supplement air to the dense powder falling from the loader to make it expand.

[0023] The vibratable powder mixing bin provided by the embodiment of the present invention increases the flow rate of the powder, achieves the effect of increasing the discharge rate and ensuring the discharge stability. Through the intermittent vibration of the vibrator, the materials are continuously dredged to improve the material flow. At the same time, the air volume required for the powder to expand in volume is supplemented through the discharge port partition frame. By mixing powders with the present invention, the phenomenon of material blockage can be reduced, the labor and material costs invested in dredging the blocked materials can be reduced, the production efficiency can be improved, and the mixing cost can be reduced. By setting the fixed bin 1 and the movable bin 2 to form a double-layer bin, the falling time of the materials can be extended to ensure that the powders can be mixed evenly.

[0024] In another embodiment, the vibratable powder mixing bin further includes four anti-sticking plates 4. The anti-sticking plates 4 are triangular in shape, and the four anti-sticking plates 4 are respectively welded at the four corners of the feeding end of the fixed bin 1. The anti-sticking plates 4 can prevent some powders with relatively high humidity from sticking to the inner wall of the fixed bin 1.

[0025] In another embodiment, the double-layer cross-shaped diverter 6 includes a first channel steel 6-1, a second channel steel 6-2 and several second angle steels 6-3. The first channel steel 6-1 and the second channel steel 6-2 are parallel and horizontally distributed up and down. The two ends of the first channel steel 6-1 are respectively welded to the bottoms of the two movable liners 5-1, and the two ends of the second channel steel 6-2 are respectively welded to the bottoms of the two movable liners 5-1. The several second angle steels 6-3 are divided into two groups. The second angle steels 6-3 in the same group are longitudinally parallel to each other. One group of second angle steels 6-3 is welded to the first channel steel 6-1, and the other group of second angle steels 6-3 is welded to the second channel steel 6-2. By setting the double-layer cross-shaped diverter 6, it can not only ensure that the powder mixing is not affected, but also transmit a relatively large vibration intensity, so that the powder can be mixed evenly.

[0026] In another embodiment, the four lifting lugs 5-2 are in the same horizontal plane, which can not only make the movable liner 5-1 fit well with the movable bin 2, but also not affect the vibration of the movable liner 5-1.

[0027] In another embodiment, anti-slip blocks 5-4 are welded to both ends of the bolt rod 5-3 to prevent the bolt rod 5-3 from slipping out of the lifting lug 5-2 during vibration.

[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
