Description

Technical Field

[0001] This utility model relates to the field of material feeding bin technology, and in particular to a material feeding dust sealing device. Background Technology

[0002] During converter charging, materials (such as lime and ore) are driven at high speed into the silo via conveyor belts. Existing silos are generally open; during material feeding, the high speed causes collisions with the silo opening and walls, generating significant amounts of dust that overflows from the silo. This dust severely pollutes the working environment, harming the health of workers, and also enters the moving parts of the equipment, leading to accelerated wear and shortening its lifespan. Furthermore, the high-speed collisions with the silo walls cause material breakage, increasing the powder content and affecting the subsequent use of the material.

[0003] To address the aforementioned problems, existing technologies lack effective solutions, and there is an urgent need for a feeding method and device that can reduce dust generation, lower material breakage rates, improve the working environment, and extend equipment lifespan. Therefore, developing a novel converter feeding system to solve these problems has significant practical importance and application value. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding and dust sealing device.

[0005] The technical solution to achieve the purpose of this utility model is: a feeding dust sealing device, including a feeding hopper, the top of which is open to form a hopper inlet, a valve plate for opening and closing the hopper inlet is provided inside the feeding hopper, and an automatic closing mechanism is provided corresponding to the valve plate, the automatic closing mechanism including a rotating shaft, a connecting rod and a counterweight, the rotating shaft being rotatably mounted on the feeding hopper, one end of the valve plate being fixedly mounted on the rotating shaft, one end of the connecting rod being fixedly connected to the rotating shaft and the other end being connected to the counterweight.

[0006] Furthermore, there are two valve plates arranged in a row to jointly open and close the hopper inlet. Each valve plate is equipped with an automatic closing mechanism. The rotating shafts of the two automatic closing mechanisms are parallel and located on the side of the two valve plates away from the center of the feeding hopper. The outer end of each valve plate is fixed to the corresponding rotating shaft. There can be one valve plate, which opens and closes the hopper inlet; or there can be two valve plates, which jointly open and close the hopper inlet. In the single-opening, single-closing valve structure formed by one valve plate, the opening and closing occurs from one side of the hopper inlet; in the double-opening, double-closing structure formed by two valve plates, the opening and closing occurs from the middle position of the hopper inlet. When feeding material into the feeding hopper, the material concentrates in the middle position of the feeding hopper. Compared to a single valve plate, the valve structure with two valve plates is more conducive to feeding.

[0007] Furthermore, the top of the feeding hopper is provided with a mounting groove, and the rotating shaft is rotatably mounted in the mounting groove. This structure is not only simple but also easy to assemble and disassemble.

[0008] Furthermore, the rotating shaft is horizontally positioned.

[0009] Furthermore, the connecting rod is mounted at the end of the rotating shaft.

[0010] The material feeding and dust sealing device of this utility model has the following advantages:

[0011] 1. Effectively prevents dust spillage and improves the working environment: By installing an automatically opening and closing valve plate at the material inlet of the feeding hopper, dynamic sealing is achieved during the material feeding process. When material is fed in, the weight of the material overcomes the weight of the counterweight, pushing the valve plate to open automatically, forming a channel that matches the material feeding amount: when the material feeding amount is large, the gravity difference is large, and the valve plate opens a larger channel; when the material feeding amount is small, the gravity difference is small, and the valve plate opens a smaller channel. This dynamic adjustment mechanism ensures that the valve plate always matches the material feeding amount, avoiding the problem of excessive opening. In addition, after the material feeding is completed, the valve plate automatically closes under the gravity of the counterweight, achieving a complete seal on the hopper inlet. Whether the valve plate is open during the feeding process or closed after the feeding is completed, the valve plate can effectively seal the hopper inlet, preventing dust spillage. This design significantly improves the working environment, reduces the health hazards of dust to operators, and reduces dust wear on equipment, extending the service life of the equipment.

[0012] 2. Simple structure and high degree of automation: The automatic closing mechanism composed of the rotating shaft, the connecting rod and the counterweight is simple and reliable in structure. It does not require additional power to drive it. The automatic opening and closing of the valve plate can be realized by the gravity of the counterweight. It has a high degree of automation and is easy to operate.

[0013] 3. Buffering the falling material to ensure material quality: The valve plate seals the hopper inlet to prevent dust leakage and also buffers the falling material, reducing the collision between the material and the hopper wall, avoiding high-speed collision and breakage of the material, increasing the powder content, and affecting the subsequent use effect of the material.

[0014] 4. Wide range of applications: This device can be widely used in various material feeding situations that require dust control, such as the feeding and conveying of powdery materials such as cement, fly ash, and mineral powder. Attached Figure Description

[0017] The preferred embodiment of the material feeding and dust sealing device of this utility model will be described in detail below with reference to the accompanying drawings:

[0018] like Figure 1 and Figure 2 As shown, a feeding dust sealing device includes a feeding hopper 1, the top of which is open to form a hopper inlet 11. The feeding hopper 1 is provided with a valve plate 2 for opening and closing the hopper inlet 11. The valve plate 2 is provided with an automatic closing mechanism 3. The automatic closing mechanism 3 includes a rotating shaft 31, a connecting rod 32, and a counterweight 33. The rotating shaft 31 is rotatably mounted on the feeding hopper 1. One end of the valve plate 2 is fixedly mounted on the rotating shaft 31. One end of the connecting rod 32 is fixedly connected to the rotating shaft 31, and the other end is connected to the counterweight 33.

[0019] This utility model relates to a material feeding and dust sealing device. The top of the feeding hopper 1 is open, forming a hopper inlet 11 for material feeding. A valve plate 2 is installed inside the feeding hopper 1 to open and close the hopper inlet 11 to prevent dust overflow. One end of the valve plate 2 is fixedly mounted on a rotating shaft 31, which is rotatably mounted on the side wall of the feeding hopper 1 to achieve the rotational opening and closing of the valve plate 2. A counterweight 33 is connected to the rotating shaft 31 via a connecting rod 32. The counterweight 33 drives the connecting rod 32 under gravity, thereby causing the rotating shaft 31 to rotate and automatically close the valve plate 2.

[0020] The present invention relates to a material feeding and dust sealing device. When material is fed into the hopper inlet 11, the valve plate 2 opens under the external force of the material. After the material is fed in, the valve plate 2 automatically closes under the gravity of the counterweight 33, thereby sealing the hopper inlet 11 and effectively preventing dust from overflowing.

[0021] The material feeding and dust sealing device of this utility model has the following advantages:

[0022] 1. Effectively prevents dust spillage and improves the working environment: By installing an automatically opening and closing valve plate 2 at the material inlet 11 of the feeding hopper 1, dynamic sealing is achieved during the material feeding process. When material is fed in, the weight of the material overcomes the weight of the counterweight 33, pushing the valve plate 2 to open automatically, forming a channel that matches the material feeding amount: when the material feeding amount is large, the gravity difference is large, and the channel opened by the valve plate 2 is large; when the material feeding amount is small, the gravity difference is small, and the channel opened by the valve plate 2 is small. This dynamic adjustment mechanism ensures that the valve plate 2 always matches the material feeding amount, avoiding the problem of excessive opening. In addition, after the material feeding is completed, the valve plate 2 automatically closes under the gravity of the counterweight 33, achieving a complete seal on the material inlet 11. Whether the valve plate 2 is open during the feeding process or closed after the feeding is completed, the valve plate 2 can effectively seal the material inlet 11, preventing dust spillage. This design significantly improves the working environment, reduces the health hazards of dust to operators, and at the same time reduces dust wear on equipment, extending the service life of the equipment.

[0023] 2. Simple structure and high degree of automation: The automatic closing mechanism 3, composed of the rotating shaft 31, the connecting rod 32 and the counterweight 33, has a simple and reliable structure. It does not require additional power to drive it. The automatic opening and closing of the valve plate 2 can be achieved by the gravity of the counterweight 33. It has a high degree of automation and is easy to operate.

[0024] 3. Buffering the falling material to ensure the quality of the material: The valve plate 2 seals the inlet 11 of the hopper to prevent dust leakage and also buffers the falling material to reduce the collision between the material and the hopper wall, avoiding high-speed collision and breakage of the material, which would increase the powder content and affect the subsequent use of the material.

[0025] 4. Wide range of applications: This device can be widely used in various material feeding situations that require dust control, such as the feeding and conveying of powdery materials such as cement, fly ash, and mineral powder.

[0026] This utility model provides a feeding and dust sealing device with simple structure, high degree of automation and good sealing performance, which can effectively prevent dust from overflowing, improve the working environment and has broad application prospects.

[0027] Preferably, the feeding and dust sealing device of this utility model includes two valve plates 2 arranged in a row to jointly open and close the hopper inlet 11. Each valve plate 2 is equipped with an automatic closing mechanism 3. The rotating shafts 31 of the two automatic closing mechanisms 3 are parallel and located on the side of the two valve plates 2 away from the center of the feeding hopper. The outer end of each valve plate 2 is fixed to the corresponding rotating shaft 31. Alternatively, there can be one valve plate 2 opening and closing the hopper inlet 11; or there can be two valve plates 2 jointly opening and closing the hopper inlet 11. In the single-opening, single-closing valve structure formed by one valve plate 2, the opening and closing occurs from one side of the hopper inlet 11; in the double-opening, double-closing structure formed by two valve plates 2, the opening and closing occurs from the middle position of the hopper inlet 11. When feeding material into the feeding hopper 1, the material is concentrated in the middle position of the feeding hopper 1. Compared with one valve plate 2, the valve structure of two valve plates 2 is more conducive to feeding.

[0028] In this utility model of a material feeding and dust sealing device, preferably, the top of the material feeding hopper 1 is provided with an installation groove 12, and the rotating shaft 31 is rotatably disposed within the installation groove 12. This structure is not only simple, but also easy to assemble and disassemble.

[0029] In the present invention, the rotating shaft 31 is preferably arranged horizontally in the feeding and dust sealing device.

[0030] In the present invention, the connecting rod 32 is preferably installed at the end of the rotating shaft 31 in the material feeding and dust sealing device.
