Description

Technical Field

[0001] This utility model relates to the field of dust collection technology, specifically a dust collection structure for feeding ferroalloy batching silos. Background Technology

[0002] Currently, the most common feeding method in the industry is belt conveyor feeding. This method, with its advantages of long conveying distance and high capacity, is widely applicable to the transfer of block materials and mixed raw materials. The specific process is as follows: ferroalloy raw materials are transferred from the stockyard to the receiving hopper at the head of the belt conveyor using a loader or grab bucket. The belt then transports the raw materials to the top of the batching silo, and finally distributes them into the corresponding silos via chutes. However, in actual production, when the belt conveyor transports the raw materials to the top of the batching silo and dumps them into the silo via chutes, the raw materials collide and impact with the existing materials and silo walls, generating a large amount of dust. Simultaneously, the falling material causes airflow disturbance, leading to dust spreading upwards to the top of the batching silo and being discharged outwards. This not only causes serious pollution to the workshop and surrounding environment, endangering the health of operators, but also may cause equipment malfunctions due to dust accumulation, affecting production continuity. Therefore, this utility model provides a dust collection structure for feeding ferroalloy batching bins. 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 As shown, a dust collection structure for feeding a ferroalloy batching silo includes a belt conveyor 1, a receiving hopper 2 at one end of the belt conveyor 1, a discharge pipe 21 installed at the bottom of the receiving hopper 2, a hemispherical shield 22 installed at the top of the receiving hopper 2, an annular pipe 3 installed on the outside of the receiving hopper 2, and several suction pipes 31 installed on the inside of the annular pipe 3, which are arranged in a circumferential array. A first connecting pipe 32 is installed on one side of the annular pipe 3, a filter box 33 is installed at one end of the first connecting pipe 32, a negative pressure machine 34 is installed at the top of the filter box 33, and a second connecting pipe 341 is installed between the negative pressure machine 34 and the filter box 33.

[0015] Specifically, when the belt conveyor 1 transports ferroalloy raw materials to the receiving hopper 2 and pours them into the batching bin, the hemispherical shield 22 forms a fully enclosed hemispherical space over the entire area where the raw materials are poured. This physically restricts the diffusion path of dust, preventing it from spreading directly into the workshop and surrounding environment. Simultaneously, the negative pressure unit 34 is activated, creating a negative pressure inside the filter box 33 via the second connecting pipe 341. This negative pressure is transmitted to the annular pipe 3 via the first connecting pipe 32, causing several circularly arrayed suction pipes 31 inside the annular pipe 3 to simultaneously generate suction. Dust generated in the receiving hopper 2 due to the collision, impact, and airflow disturbance of the raw materials is drawn into the annular pipe 3 from all directions without any blind spots under the uniform suction of the circular array suction pipes. The dust then enters the filter box 33 via the first connecting pipe 32, where it is intercepted and purified. Finally, clean air is discharged from the negative pressure unit 34 and passes through the hemispherical shield 22. The active dust extraction system, consisting of a filter box 33, a negative pressure unit 34, a second connecting pipe 341, and a first connecting pipe 32, achieves physical containment of dust diffusion. This system, along with several suction pipes 31 arranged in a circular array on the inner side of the annular pipe 3, provides multiple beneficial effects: First, it can collect dust generated during the feeding process from the belt conveyor 1 to the receiving hopper 2 in all directions, preventing its diffusion into the workshop and surrounding environment, effectively improving the production environment and protecting the health of operators. Second, the uniform suction design of the circular array suction pipes 31 efficiently captures all dust within the enclosed space of the hemispherical shield 22, preventing dust accumulation on the receiving hopper 2, the discharge pipe 21, and the surfaces of surrounding equipment, reducing the probability of equipment failure caused by dust and ensuring production continuity. Third, the filter box 33 effectively purifies the inhaled dust, preventing dust-laden air from being directly discharged through the negative pressure unit 34, thus avoiding secondary pollution and meeting environmental protection requirements.

[0016] In one embodiment of this utility model, such as Figures 1-4 As shown, a support frame 11 is installed at the bottom of the belt conveyor 1, a support ring 12 is installed inside the support frame 11, a receiving hopper 2 is installed at the top of the support ring 12, and a discharge pipe 21 is inserted into the inside of the support ring 12.

[0017] Specifically, the belt conveyor 1 is stably supported by the support frame 11 at the bottom. The support ring 12 on the inner side of the support frame 11 provides an installation base for the receiving hopper 2, so that the receiving hopper 2 is stably placed on the top of the support ring 12. At the same time, the discharge pipe 21 is inserted into the inside of the support ring 12, forming a rigid connection between the receiving hopper 2 and the support structure.

[0018] In one embodiment of this utility model, such as Figures 1-4 As shown, an extension frame 13 is installed at one end of the support frame 11, and the filter box 33 is installed at the top of the extension frame 13.

[0019] Specifically, the extension frame 13 at one end of the support frame 11 provides a stable mounting carrier for the filter box 33, so that the filter box 33 and the support frame 11 form an integrated structure through the extension frame 13, realizing a close-range rigid connection between the filter box 33 and core components such as the belt conveyor 1 and the receiving hopper 2.

[0020] In one embodiment of this utility model, such as Figures 1-4 As shown, a sealing ring plate 23 is slidably connected to the outside of the discharge pipe 21. A support plate 24 is provided at the top of the sealing ring plate 23. The support plate 24 is installed on the side wall of the support ring 12. A lifting adjustment screw 25 is threadedly connected to the inner wall of the support plate 24. The lifting adjustment screw 25 is rotatably connected to the top of the sealing ring plate 23.

[0021] Specifically, the sealing ring plate 23 on the outside of the discharge pipe 21 can slide along the axial direction of the discharge pipe 21. The sealing ring plate 23 blocks the top opening of the batching bin. The support plate 24 on the side wall of the support ring 12 provides installation support for the lifting adjustment screw 25. When the lifting adjustment screw 25 is rotated, it generates axial displacement under the action of the thread on the inner wall of the support plate 24, which in turn drives the sealing ring plate 23, which is rotatably connected to it, to slide up and down along the discharge pipe 21, thereby realizing the opening and closing adjustment and sealing of the gap between the discharge pipe 21 and the feed inlet of the batching bin.

[0022] In one embodiment of this utility model, such as Figures 1-4 As shown, a slanted opening is provided on one side of the top opening of the receiving hopper 2, and the belt conveyor 1 is positioned corresponding to the slanted opening.

[0023] Specifically, the inclined design allows raw materials to enter the receiving hopper 2 along an inclined path, reducing the impact force of the falling raw materials and the collision intensity with the inner wall of the receiving hopper 2, thereby reducing the amount of dust generated at the source. At the same time, the inclined opening is precisely aligned with the belt conveyor 1 to prevent raw materials from leaking out and spilling. Combined with the hemispherical shield 22 and the negative pressure dust extraction system, it further improves the dust collection efficiency, reduces the diffusion of dust to the surrounding environment, reduces the harm to the health of operators and the risk of equipment failure, and ensures the continuity of production.

[0024] In one embodiment of this utility model, such as Figures 1-4 As shown, a drive motor 4 is installed at the top of the hemispherical shield 22, a rotating rod 41 is installed at the output end of the drive motor 4, and several actuating rods 42 are installed on the outside of the rotating rod 41. The actuating rods 42 are located inside the discharge pipe 21.

[0025] Specifically, after the drive motor 4 at the top of the hemispherical shield 22 is started, its output end drives the rotating rod 41 to rotate. Several actuating rods 42 on the outside of the rotating rod 41 rotate synchronously with the rotating rod 41 inside the discharge pipe 21, which actuates and guides the iron alloy raw material falling in the discharge pipe 21, thus preventing the raw material from accumulating and blocking in the discharge pipe 21.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Working principle: During operation, the belt conveyor 1 transports the ferroalloy raw material through the corresponding inclined opening at the top of the receiving hopper 2 into the receiving hopper 2. The inclined opening design reduces the impact and collision intensity of the raw material to reduce dust generation. The receiving hopper 2 is securely installed by the support ring 12 on the inner side of the support frame 11, and the discharge pipe 21 is inserted into the support ring 12 to ensure the stability of the overall structure. When the raw material is poured, the hemispherical shield 22 forms a closed space to limit the diffusion of dust. At the same time, the negative pressure machine 34 is started, and the filter box 33 is generated by the second connecting pipe 341. This negative pressure is transmitted to the annular pipe 3 through the first connecting pipe 32, causing the inner circumferential array to distribute the dust. The suction pipe 31 of the cloth generates uniform suction, drawing the dust in the receiving hopper 2 into the annular pipe 3 from all directions, and then into the filter box 33 for purification through the first connecting pipe 32. The clean air is discharged by the negative pressure machine 34. The filter box 33 is integrated into the support frame 11 through the extension frame 13 to ensure stable negative pressure. In addition, rotating the lifting adjustment screw 25 on the support plate 24 can drive the sealing ring plate 23 to slide along the discharge pipe 21, sealing the gap between the discharge pipe 21 and the batching bin. The drive motor 4 drives the rotating rod 41 and the actuating rod 42 to rotate in the discharge pipe 21, guiding the raw materials to avoid blockage and further reducing dust generation and overflow.
