Description

Technical Field

[0001] This utility model belongs to the field of metallurgical blast furnace charging technology, and in particular relates to a sintering feeding device for a transfer station in front of the blast furnace. Background Technology

[0002] In blast furnace sinter charging systems, traditional transfer stations use single-outlet hoppers. When alternating feeding to two blast furnaces (such as No. 2 and No. 3), frequent starting and stopping of belt conveyors and back-and-forth transport of sinter are necessary, leading to the following problems:

[0003] Low material replenishment efficiency: Each time the material supply target is changed, the conveyor belt needs to be stopped and the direction adjusted, which prolongs the replenishment time;

[0004] High energy consumption: Frequent start-stop of the belt increases motor energy consumption and mechanical wear;

[0005] High operational intensity: The belt control system requires repeated manual operation. Utility Model Content

[0006] This invention addresses the problems of low feeding efficiency, high energy consumption, and heavy operational intensity in traditional blast furnace sinter feeding systems. It provides a sinter feeding device for a transfer station in front of the blast furnace, which can reduce the number of belt reversals and avoid frequent belt starts and stops.

[0007] The technical solution adopted by the sintering feeding device of the pre-tank transfer station of this utility model is as follows:

[0008] A sintering feeding device for a transfer station in front of a tank includes a trolley and a feeding hopper connected to the trolley. The feeding hopper is provided with a vertical partition that divides the interior of the feeding hopper into a left feeding channel and a right feeding channel. The left feeding channel and the right feeding channel are each connected to a hopper. The partition is hinged with a left rotating flap for closing the left feeding channel and a right rotating flap for closing the right feeding channel. The left rotating flap and the right rotating flap alternately flip up and down.

[0009] A further improvement of this utility model is that: the top of the partition is provided with a rotating shaft connected to the left rotating flap and the right rotating flap, and the included angle between the left rotating flap and the right rotating flap is 110°-150°; wherein, when the left rotating flap tilts upward to close the left material channel, the right rotating flap tilts downward to the right to open the right material channel, and when the right rotating flap tilts upward to close the right material channel, the left rotating flap tilts downward to the left to open the left material channel.

[0010] A further improvement of this utility model is that electromagnetic chucks for adsorbing the left-rotating flip plate and the right-rotating flip plate are respectively provided on the left and right sides of the partition.

[0011] A further improvement of this utility model is that: the inner wall of the hopper is provided with a rotating shaft connected to the left rotating flap and the right rotating flap respectively at the positions of the left rotating flap and the right rotating flap; wherein, when the left rotating flap and the right rotating flap rotate upward 90° to the vertical state, the corresponding material channel opens, and when the left rotating flap and the right rotating flap rotate downward 90° to the horizontal state, the corresponding material channel closes.

[0012] A further improvement of this utility model is that: the two sides of the partition are provided with blocks for supporting the left-rotating flap and the right-rotating flap.

[0013] A further improvement of this utility model is that: the end of the rotating shaft extends horizontally to the outside of the hopper and is fixedly fitted with a driven wheel, while the outer wall of the hopper is provided with a driving wheel connected to the driven wheel via a transmission belt.

[0014] A further improvement of this utility model is that sealing strips are provided on the edges of both the left-rotating flap and the right-rotating flap.

[0015] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0016] This invention, through the design of a partition, can divide the raw material hopper into two material channels, enabling the feeding of materials to two hoppers without the need for frequent belt starts and stops, thus reducing the number of belt reversals. Furthermore, by rotating a left or right rotating flap, the corresponding material channel can be opened or closed according to actual conditions, thereby enabling the feeding or stopping of the corresponding hopper.

[0017] When the rotating shaft is positioned at the top of the partition in this invention, the left and right rotating flaps can be alternately flipped up and down using a single rotating shaft. Simultaneously, since the included angle between the left and right rotating flaps is 110°-150°, when the left and right rotating flaps close the corresponding material channels, the side walls of the lower hopper tilt upwards, allowing the sintered material above the closed material channel to be discharged into the open material channel due to the slope. At the same time, the electromagnetic chuck can attract the rotating flaps and partitions corresponding to the open material channel together, thus preventing the rotating flaps corresponding to the closed material channel from rotating downwards due to the impact of the sintered material.

[0018] When the central rotating shaft of this invention is installed on the inner wall of the hopper, it can control the rotation of the left and right rotating flaps separately, thereby opening one material channel and closing one material channel, or opening both material channels simultaneously, or closing both material channels simultaneously. At the same time, the set stop blocks can support the corresponding rotating flap upward when the corresponding material channel is closed, preventing the corresponding rotating flap from rotating downward due to the impact of the sintered material.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0028] First refer to Figures 1-4 As can be seen, this utility model includes a trolley (and a conveyor belt in conventional technology), which is connected to a hopper 1. The inner wall of the hopper 1 is fixedly connected (e.g., by welding or bolting) with a vertical partition 11, which divides the interior of the hopper 1 into a left material channel 12 and a right material channel 13. Each material channel is connected to a hopper. A left rotating flap 2 for closing the left material channel 12 is provided inside the hopper 1 at the position corresponding to the left material channel 12, and a right rotating flap 3 for closing the right material channel 13 is provided inside the hopper 1 at the position corresponding to the right material channel 13.

[0029] Both the left-rotating flap 2 and the right-rotating flap 3 mentioned above are made of materials that can be magnetically attracted (such as alloys containing iron, nickel, cobalt, etc.).

[0030] Example 1

[0031] like Figure 1and Figure 2 As shown, in this embodiment, the top of the partition 11 is hinged to a rotating shaft 4. The side walls of the left rotating flap 2 and the right rotating flap 3 are fixedly connected to the rotating shaft 4. Under the action of the rotating shaft 4, the left rotating flap 2 and the right rotating flap 3 alternately flip up and down. That is, when the left rotating flap 2 flips down to open the left material channel 12, the right rotating flap 3 flips up to close the right material channel 13; when the left rotating flap 2 flips up to close the left material channel 12, the right rotating flap 3 flips down to open the right material channel 13. The included angle between the left rotating flap 2 and the right rotating flap 3 is 110°-150°. In this embodiment, the included angle between the left rotating flap 2 and the right rotating flap 3 is 130°. When the left rotating flap 2 closes the left material channel 12, the left rotating flap 2 tilts downward from the inner wall of the hopper 1 toward the partition 11, and the angle between the left rotating flap 2 and the horizontal plane is 20°. At this time, the right rotating flap 3 tilts downward to the right in the right material channel 13, and the angle between the right rotating flap 3 and the partition 11 is also 20°. When the right rotating flap 3 closes the left material channel 12, the right rotating flap 3 tilts downward from the inner wall of the hopper 1 toward the partition 11, and the angle between the right rotating flap 3 and the horizontal plane is 20°. At this time, the left rotating flap 2 tilts downward to the left in the left material channel 12, and the angle between the left rotating flap 2 and the partition 11 is also 20°.

[0032] In this embodiment, electromagnetic chucks 5 are fixed on the left and right sides of the partition 11 respectively. When the left rotating flap 2 closes the left material channel 12, the electromagnetic chuck 5 located on the right side of the partition 11 contacts the right rotating flap 3 and holds the right rotating flap 3 in place. When the right rotating flap 3 closes the right material channel 13, the electromagnetic chuck 5 located on the left side of the partition 11 contacts the left rotating flap 2 and holds the left rotating flap 2 in place.

[0033] In this embodiment, to facilitate the driving of the rotating shaft 4, one end of the rotating shaft 4 extends horizontally to the outside of the hopper 1 and is fixedly fitted with a driven wheel 41. At the same time, a stepper motor is fixed to the outer wall of the hopper 1, and a driving wheel 7 is fixed to the output shaft of the stepper motor. The driving wheel 7 is connected to the driven wheel 41 through a transmission belt 8.

[0034] In this embodiment, a single rotating shaft 4 enables the left rotating flap 2 and the right rotating flap 3 to alternately flip up and down. Simultaneously, since the included angle between the left rotating flap 2 and the right rotating flap 3 is 130°, when the left rotating flap 2 and the right rotating flap 3 close the corresponding material channel, the left rotating flap 2 and the right rotating flap 3 tilt upwards towards the side wall of the lower hopper 1. Therefore, the sintered material above the closed material channel can be discharged into the open material channel under the influence of the slope. At the same time, the electromagnetic chuck 5 can attract the rotating flap and the partition 11 corresponding to the open material channel together, thereby preventing the rotating flap corresponding to the closed material channel from rotating downwards due to the impact of the sintered material.

[0035] The working principle of the sintering feeding device at the pre-tank transfer station in this embodiment is as follows:

[0036] When it is necessary to open the left material channel 12 and close the right material channel 13, the stepper motor drives the drive wheel 7 to rotate, which in turn drives the driven wheel 41 and the rotating shaft 4 to rotate. Under the action of the rotating shaft 4, the left rotating flap 2 and the right rotating flap 3 rotate counterclockwise until the left rotating flap 2 comes into contact with the electromagnetic chuck 5 located on the left side of the partition 11. At this time, the electromagnetic chuck 5 is energized and attracts the left rotating flap 2.

[0037] When it is necessary to open the right material channel 13 and close the left material channel 12, the first step is to de-energize the electromagnetic chuck 5 located on the left side of the partition 11. Then, the stepper motor drives the drive wheel 7 to rotate, which in turn drives the driven wheel 41 and the rotating shaft 4 to rotate. Under the action of the rotating shaft 4, the left rotating flap 2 and the right rotating flap 3 rotate clockwise until the right rotating flap 3 comes into contact with the electromagnetic chuck 5 located on the right side of the partition 11. At this time, the electromagnetic chuck 5 is energized and attracts the right rotating flap 3.

[0038] Example 2

[0039] like Figure 3 and Figure 4 As shown, in this embodiment, the two inner walls of the hopper 1 are respectively hinged with rotating shafts 4 at positions corresponding to the left rotating flap 2 and the right rotating flap 3, and each rotating shaft 4 is fixedly connected to the edge of the corresponding rotating flap. Meanwhile, one end of each rotating shaft 4 extends horizontally outside the hopper 1 and is fixedly fitted with a driven wheel 41.

[0040] Meanwhile, a stepper motor is fixed on the outer wall of the hopper 1 below each passive wheel 41, and an active wheel 7 is fixed on the output shaft of each stepper motor. Each active wheel 7 is connected to the passive wheel 41 above through a transmission belt 8.

[0041] In this embodiment, when the left rotating flap 2 and the right rotating flap 3 rotate upward 90° to a vertical state, they fit against the inner wall of the hopper 1, and the corresponding material channel is opened; when the left rotating flap 2 and the right rotating flap 3 rotate downward 90° to a horizontal state, the corresponding material channel is closed.

[0042] To ensure upward support of the corresponding rotating flap when the corresponding material channel is closed, preventing the corresponding rotating flap from rotating downward due to impact from the sintered material, in this embodiment, baffles 6 are provided on both sides of the partition 11 to support the left rotating flap 2 and the right rotating flap 3. When the left rotating flap 2 and / or the right rotating flap 3 are in a horizontal state, the bottom of the left rotating flap 2 and / or the right rotating flap 3 are in contact with the corresponding baffles 6.

[0043] The working principle of the sintering feeding device at the pre-tank transfer station in this embodiment is as follows:

[0044] When it is necessary to open the left feed channel 12 and close the right feed channel 13, the left rotating flap 2 is rotated 90° counterclockwise by the rotating shaft 4 corresponding to the left rotating flap 2, and the right rotating flap 3 is rotated 90° counterclockwise by the rotating shaft 4 corresponding to the right rotating flap 3.

[0045] When it is necessary to open the right material channel 13 and close the left material channel 12, the left rotating flap 2 is rotated 90° clockwise by the rotating shaft 4 corresponding to the left rotating flap 2, and the right rotating flap 3 is rotated 90° clockwise by the rotating shaft 4 corresponding to the right rotating flap 3.

[0046] When it is necessary to open the left feed channel 12 and the right feed channel 13 at the same time, the left rotating flap 2 is rotated 90° counterclockwise by the rotating shaft 4 corresponding to the left rotating flap 2, and the right rotating flap 3 is rotated 90° clockwise by the rotating shaft 4 corresponding to the right rotating flap 3.

[0047] When it is necessary to close the left material channel 12 and the right material channel 13 at the same time, the left rotating flap 2 is rotated 90° clockwise by the rotating shaft 4 corresponding to the left rotating flap 2, and the right rotating flap 3 is rotated 90° counterclockwise by the rotating shaft 4 corresponding to the right rotating flap 3.

[0048] In the two embodiments described above, in order to enhance the sealing effect of the left rotating flap 2 and the right rotating flap 3, sealing strips are provided on the edges of both the left rotating flap 2 and the right rotating flap 3.

[0049] In the above embodiments, the present invention provides a sintering feeding device for a transfer station in front of the tank. The present invention can divide the raw material hopper into two material channels by setting a partition. The two material channels can realize the purpose of feeding material to two silos, thereby eliminating the need to frequently start and stop the belt and reducing the number of belt transfers. At the same time, the present invention can open or close the corresponding material channel according to the actual situation by rotating the left or right rotating flap, thereby realizing the feeding or stopping of the corresponding silo.

[0050] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
