Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of diversion device technology, and more specifically, to a coke powder diversion device for a coke chute. Background Technology

[0002] Coke chutes are key equipment in coke conveying systems used to guide coke from a high level to a low level. They are widely used in coking plants, steel plants and other scenarios. Their performance directly affects conveying efficiency, equipment wear and tear and production safety. Coke chutes are mostly inclined, with the inlet connected to the upstream equipment and the outlet connected to the downstream equipment.

[0003] During the production and processing of coke, a byproduct with small particle size, coke dust, is produced. Lump coke has good permeability and high mechanical strength, and is a key raw material for core industrial processes such as blast furnace ironmaking, casting, and calcium carbide production. Coke dust, due to its fine particle size and large specific surface area, is more suitable as a reducing agent for boiler fuel. Therefore, when transporting coke, a diversion device is usually used to separate it.

[0004] When coke passes through a coke chute, a screen is installed inside. Smaller coke particles pass through the screen holes and fall to the bottom of the chute, while larger coke lumps slide down above the screen, thus being separated. However, when the coke particles fall, they usually fall directly to the bottom of the coke chute, generating a large amount of dust. This dust floats in the environment and can cause some impact. Furthermore, workers will also absorb some dust during subsequent collection, which can be harmful to their health. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a coke dust diversion device for a coke chute, which solves the technical problem in the prior art that dust is easily generated when coke dust falls, and then floats into the environment.

The dust cover is fixedly installed at the discharge port at the bottom of the chute body, the telescopic cover is slidably installed inside the dust cover through the telescopic component, the dustproof component is disposed at the bottom end of the telescopic cover, and the fixing component is disposed on the side of the dust cover for fixing the dustproof component.

[0007] Furthermore, the telescopic assembly includes a sliding plate, a sliding rod, and an adjustment assembly. Two sliding plates are provided, and both sliding plates are fixedly installed on the support frame. The sliding rod is slidably installed on the side of the sliding plate, and the telescopic cover is fixedly installed between the two sliding rods. The adjustment assembly is provided on the support frame.

[0008] Furthermore, the adjustment assembly includes a support cover, a reciprocating screw, a first motor, and a synchronization component. Two support covers are mounted on the support frame. The reciprocating screw is rotatably mounted inside one of the support covers and a matching crescent-shaped slider is mounted on the reciprocating screw. The first motor is mounted on the support cover and its output end is coaxially connected to the reciprocating screw. The synchronization component is disposed inside the other support cover.

[0009] Furthermore, the synchronization component includes a synchronization rod and a synchronization block.

[0018] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0019] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0020] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0021] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-5 As shown, it illustrates a coke powder diversion device for a coke chute according to an embodiment of the present disclosure, including a chute body 2 mounted on a support frame 1, a discharge port being provided at the bottom of the chute body 2, and also including a dust cover 3, a telescopic cover 4, a dustproof component, and a fixing component. The dust cover 3 is fixedly installed at the discharge port at the bottom of the chute body 2, the telescopic cover 4 is slidably installed inside the dust cover 3 through the telescopic component, the dustproof component is disposed at the bottom end of the telescopic cover 4, and the fixing component is disposed on the side of the dust cover 3 for fixing the dustproof component.

[0025] When diverting coke dust, the coke is first poured into the chute body 2. The chute body 2 is equipped with a filter plate. Because the chute body 2 is installed at an incline on the support frame 1, the coke can slide down the filter plate. The vibrating screen can also be used to drive the chute body 2 to vibrate. The larger coke particles slide down the filter plate, while the smaller coke particles fall through the filter plate to the discharge port of the chute body 2. A collection box can be placed at the discharge port before this.

[0026] like Figure 2 and Figure 3 As shown, during material feeding, because the top area of ​​the dust cover 3 is larger than the area of ​​the discharge port of the chute body 2, the dust cover 3 can block some of the generated dust. Furthermore, it can move up and down according to the height of the collection box via the telescopic assembly, thus approaching the collection box. The telescopic assembly includes a sliding plate 5, a sliding rod 6, and an adjustment component. Two sliding plates 5 are provided, both fixedly mounted on the support frame 1. Sliding rods 6 are slidably mounted on the sides of the sliding plates 5, and the telescopic cover 4 is fixedly mounted between the two sliding rods 6. The adjustment component is located on the support frame 1 and includes a support cover 7, a reciprocating screw 8, a first motor 10, and... The synchronization component consists of two support covers 7 mounted on the support frame 1. A reciprocating screw 8 is rotatably mounted inside one of the support covers 7, and a matching crescent-shaped slider 9 is mounted on the reciprocating screw 8. A first motor 10 is mounted on the support cover 7, and the output end of the first motor 10 is coaxially connected to the reciprocating screw 8. The synchronization component is located inside the other support cover 7. The synchronization component includes a synchronization rod 11 and a synchronization block 12. The synchronization rod 11 is fixedly mounted inside the other support cover 7, and the synchronization block 12 is slidably mounted on the synchronization rod 11. A connecting ring 13 is fixedly mounted on both the synchronization block 12 and the crescent-shaped slider 9, and the two connecting rings 13 are respectively fixedly connected to the two sliding rods 6.

[0027] Specifically, when the first motor 10 is started, its output drives the reciprocating screw 8 to rotate within the support cover 7. This causes the crescent-shaped slider 9 to move up and down on the reciprocating screw 8, thereby causing the connecting ring 13 and one of the sliding rods 6 to slide on the sliding plate 5. Connected by the telescopic cover 4, this causes the other sliding rod 6 to slide on the sliding plate 5, simultaneously driving the synchronizing block 12 to slide on the synchronizing rod 11. This causes the telescopic cover 4 to slide down within the dust cover 3, increasing the dustproof height and fitting snugly against the top of the collection box. To minimize dust escape, it should be noted that the shape of the crescent-shaped slider 9 matches the helical groove of the reciprocating screw 8. When the reciprocating screw 8 rotates, the sidewall of the helical groove will generate an axial thrust on the crescent-shaped slider 9 embedded therein. The crescent-shaped slider 9 can move along the axial trajectory of the reciprocating screw 8, thereby moving up and down. When the crescent-shaped slider 9 reaches the end of the reciprocating screw 8, it will smoothly transition to the reverse helical groove, thereby realizing reciprocating movement. This is a well-known technology and will not be described in detail here.

[0028] like Figure 4 and Figure 5 As shown, if the height of the collection box is low or the telescopic cover 4 does not need to be moved, the height of the dustproof can be increased by the dustproof component. The dustproof component includes a telescopic cylinder 14 and a dustproof hopper 15. One end of the telescopic cylinder 14 is fixedly installed at the bottom of the telescopic cover 4, and the dustproof hopper 15 is fixedly installed at the other end of the telescopic cylinder 14. Specifically, when the telescopic cylinder 14 is pulled, it can be pulled up and down, similar to a corrugated pipe, which causes the dustproof hopper 15 to move down and fit against the collection box, thereby preventing dust. When it is not necessary to pull, it can be fixed by the fixing component. The fixing component includes a fixing frame 16, a connecting line 17, and a hook 18. The fixing frame 16 is fixedly installed on both sides of the dust cover 3, and the connecting line 17 is fixedly installed on both sides of the dustproof hopper 15. The other end of the connecting line 17 is fixedly installed on the hook 18. Specifically, when the telescopic cylinder 14 is compressed and the hook 18 is hooked onto the fixing frame 16, the dustproof hopper 15 and the telescopic cylinder 14 are fixed by the connecting rope.

[0029] Working principle: When diverting and preventing dust from coke dust, the dust cover 3 first blocks some of the generated dust and starts the first motor 10. The output end of the first motor 10 drives the reciprocating screw 8 to rotate inside the support cover 7. The crescent slider 9 moves up and down on the reciprocating screw 8, thereby driving the connecting ring 13 and one of the sliding rods 6 to slide on the sliding plate 5. Under the connection of the telescopic cover 4, it drives the other sliding rod 6 to slide on the sliding plate 5, and simultaneously drives the synchronizing block 12 to slide on the synchronizing rod 11, thereby driving the telescopic cover 4 to slide down inside the dust cover 3, increasing the height of dust prevention, fitting the top of the collection box, and preventing dust from escaping to the greatest extent. It can also pull the telescopic cylinder 14, which can be pulled up and down, similar to a corrugated pipe, thereby driving the dust hopper 15 to move down and fit into the collection box, thus preventing dust.

[0030] It should be added that the reciprocating screw 8 is equipped with a telescopic protective cover, which can protect the reciprocating screw 8, and a generator can be installed on the outside of the device to supply power to the first motor 10.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure 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 solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
