Description

Technical Field

[0001] This utility model relates to the field of charging chute technology, specifically to a blast furnace charging chute. Background Technology

[0002] In blast furnaces for ironmaking, the charging chute is a key equipment component, whose main function is to evenly distribute raw materials such as iron ore and coke into the blast furnace.

[0003] According to a published specification (Publication No.: CN210856184U), a blast furnace charging chute comprises a chute body with a square cross-section and an open top in the conveying direction, and a wear-resistant liner installed within the chute body and conforming to its shape. The chute body includes several chute units connected end-to-end, which are detachably connected. Each chute unit is fixedly connected to the wear-resistant liner. This design allows the chute body to be composed of several connected chute units, enabling the transfer of smaller chute units (compared to a single-piece chute) during chute transport. This reduces the difficulty of transportation and the required external conditions. Furthermore, after rapid transfer to the destination, on-site assembly can be performed, reducing the manpower and material resources required during chute transportation.

[0004] In the aforementioned applications, while dividing the chute body into several chute units reduces transportation difficulty, this modular design may lead to wear risks at the joints in the actual blast furnace operating environment, affecting the uniformity of charge distribution and the service life of the equipment. Therefore, we propose a blast furnace charging chute. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a blast furnace charging chute, which solves the technical problems of easy wear and tear on the chute body and lack of buffering during material feeding in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a blast furnace charging chute, comprising: a goose head body, the top of the chute body being fixedly connected to the goose head body, an eccentric pin being rotatably connected through the side of the goose head body, and a wear-resistant and shock-absorbing device being provided on the inner wall of the chute body.

[0007] The wear-resistant and shock-absorbing device includes a sliding plate, which is fixedly connected to the inner wall of the chute body.

A material distribution plate is fixedly connected to the inner circumferential surface of the secondary wear-resistant plate. A first baffle plate is fixedly connected to the inner circumferential surface of the secondary wear-resistant plate. A first discharge buffer plate is fixedly connected to the side of the first baffle plate. A first buffer material distribution plate is fixedly connected to the side of the first discharge buffer plate. A first buffer spring is fixedly connected to the side of the first discharge buffer plate.

[0008] For example, in at least one embodiment of this utility model, a blast furnace charging chute further includes a connecting support plate. The connecting support plate is fixedly connected to the top of the chute body, and a reinforced outer protective plate is bolted to the circumferential surface of the chute body. Its function is to enhance the structural strength of the chute body and improve its overall stability and durability. The connecting support plate not only provides additional support for the chute body but also helps maintain its balance during use.

[0009] Two connecting support plates are arranged in a linear array along the top of the chute body, and several reinforcing outer protective plates are arranged in a linear array along the circumference of the chute body. Their function is to further enhance the structural strength and stability of the blast furnace charging chute. The linear array of connecting support plates and reinforcing outer protective plates ensures the overall structural strength of the chute body.

[0010] Several material distribution plates are arranged linearly along the inner circumference of the initial wear-resistant plate, and several material distribution plates are arranged linearly along the inner wall of the middle wear-resistant plate. Their function is to ensure uniform material distribution within the wear-resistant and shock-absorbing device, improving material distribution efficiency and quality. The linear arrangement of the material distribution and material distribution plates helps achieve uniform material distribution, preventing material accumulation or gaps during the distribution process, thereby improving the blast furnace's production efficiency and product quality.

[0011] The end of the first buffer spring away from the first feeding buffer plate is fixedly connected to the inner circumferential surface of the chute body, and the end of the second buffer spring away from the second feeding buffer plate is fixedly connected to the inner circumferential surface of the chute body. Their function is to provide additional cushioning, reducing the impact and wear on the chute body during material descent. The use of buffer springs one and two effectively absorbs the impact force generated when material falls.

[0012] The first type of feeding buffer plate is provided in two, and is symmetrically distributed along the vertical central axis of the second type of feeding buffer plate. The second type of buffer spring is provided in several, and is linearly arrayed along the bottom of the second type of feeding buffer plate. Its function is to further enhance the buffering effect of the first type of feeding buffer plate and the second type of feeding buffer plate, and ensure that the material can be smoothly dispersed onto the feeding plate during the falling process.

[0013] According to another aspect, at least one embodiment of this utility model also provides a blast furnace charging chute, comprising: a dust adsorption device, wherein the dust adsorption device is provided on the side of the chute body, the dust adsorption device includes a connecting pipe, the connecting pipe is fixedly connected to the side of the chute body, a bellows is fixedly connected to the end of the connecting pipe away from the chute body, a motor is fixedly connected to the inner wall of the bellows, a fan is fixedly connected to the output shaft of the motor, slots are opened on the side of the bellows, a baffle plate is fixedly connected to the inner side of the chute body, and a reinforcing column is fixedly connected to the side of the bellows. Its function is that when the material comes down and is conveyed onto the chute body, a large amount of dust will be generated, and the dust adsorption device adsorbs it, reducing the dust during charging, improving the quality of the working environment, and also protecting the health of the operators.

[0014] For example, at least one embodiment of this utility model provides a blast furnace charging chute, which further includes: a protective plate; the protective plate is fixedly connected to the side of the bellows; a filter plate is inserted into the top of the bellows; an inspection hole is provided on the side of the bellows; and a door panel is provided on the inner wall of the inspection hole. The function of the protective plate is to effectively protect the bellows from impacts by external objects, thereby improving the safety and durability of the entire dust adsorption device.

[0015] The end of the reinforcing column furthest from the bellows is fixedly connected to the side of the chute body. Two reinforcing columns and two motors are provided, symmetrically distributed along the vertical central axis of the connecting pipe. Their function is to further enhance the structural strength and stability of the dust adsorption device. The reinforcing columns effectively support the bellows and motors, preventing them from shaking or vibrating during operation, thereby improving the stability and durability of the entire device.

[0016] The connecting pipe penetrates the interior of the chute body. Several through slots are linearly arranged along the side of the protective plate to facilitate airflow and improve the adsorption efficiency of the dust adsorption device. The linear array design of the through slots ensures uniform airflow, thereby enhancing the adsorption effect of the dust adsorption device.

[0017] The beneficial effects of the embodiments of this utility model are as follows: 1.

[0022] The present invention 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 invention and not intended to limit its scope.

[0028] like Figures 1-5 As shown, it illustrates a blast furnace charging chute in one embodiment of the present invention, comprising: a chute body 1, a goose head body 2 fixedly connected to the top of the chute body 1, an eccentric pin 3 rotatably connected through the side of the goose head body 2, and a wear-resistant and shock-absorbing device 4 provided on the inner wall of the chute body 1.

[0029] The wear-resistant and shock-absorbing device 4 includes a slide plate 401, which is fixedly connected to the inner wall of the chute body 1. A primary wear-resistant plate 402 is bolted to the inner side of the slide plate 401. A material distribution plate 403 is fixedly connected to the inner circumferential surface of the primary wear-resistant plate 402. A secondary wear-resistant plate 404 is fixedly connected to the side of the primary wear-resistant plate 402. A material distribution plate 405 is fixedly connected to the inner circumferential surface of the secondary wear-resistant plate 404. A baffle plate 406 is fixedly connected to the inner circumferential surface of the secondary wear-resistant plate 404. The side of the baffle plate 406 is fixedly connected to... A material feeding buffer plate 407 is connected to the material feeding buffer plate 407. A material feeding cloth plate 408 is fixedly connected to the side of the material feeding buffer plate 407. A material feeding spring 409 is fixedly connected to the side of the material feeding buffer plate 407. A material baffle plate 410 is fixedly connected to the inner circumference of the middle wear-resistant plate 404. A material feeding buffer plate 411 is fixedly connected to the side of the material baffle plate 410. A material feeding cloth plate 412 is fixedly connected to the side of the material feeding buffer plate 411. A material feeding spring 413 is fixedly connected to the side of the material feeding buffer plate 411.

[0030] In some examples, a connecting support plate 5 is fixedly connected to the top of the chute body 1, and a reinforced outer protective plate 6 is bolted to the circumferential surface of the chute body 1. Its function is to enhance the structural strength of the chute body 1 and improve its overall stability and durability. The connecting support plate 5 not only provides additional support for the chute body 1 but also helps maintain its balance during use.

[0031] Two connecting support plates 5 are arranged in a linear array along the top of the chute body 1, and several reinforcing outer protective plates 6 are arranged in a linear array along the circumference of the chute body 1. Their function is to further enhance the structural strength and stability of the blast furnace charging chute. The linear array of connecting support plates 5 and reinforcing outer protective plates 6 ensures the overall structural strength of the chute body 1.

[0032] Several material distribution plates 403 are arranged linearly along the inner circumference of the initial wear-resistant plate 402, and several material distribution plates 405 are arranged linearly along the inner wall of the middle wear-resistant plate 404. Their function is to ensure that the material is evenly distributed within the wear-resistant and shock-absorbing device 4, thereby improving the material distribution efficiency and quality. The linear arrangement of the material distribution plates 403 and material distribution plates 405 helps to achieve uniform material distribution and avoids material accumulation or gaps during the material distribution process, thus improving the blast furnace's production efficiency and product quality.

[0033] The end of buffer spring 409 furthest from the discharge buffer plate 407 is fixedly connected to the inner circumferential surface of the chute body 1, and the end of buffer spring 413 furthest from the discharge buffer plate 411 is also fixedly connected to the inner circumferential surface of the chute body 1. Their function is to provide additional cushioning, reducing the impact and wear on the chute body 1 during material descent. Through the installation of buffer springs 409 and 413, the impact force generated during material descent can be effectively absorbed.

[0034] There are two material feeding buffer plates 407, which are symmetrically distributed along the vertical central axis of the material feeding buffer plate 411. There are several buffer springs 413, which are linearly arrayed along the bottom of the material feeding buffer plate 411. Their function is to further enhance the buffering effect of the material feeding buffer plates 407 and 411, and ensure that the material can be smoothly dispersed onto the material distribution plate 405 during the falling process.

[0035] For example, such as Figures 1-5As shown, when the material enters the chute body 1 from the goose head 2, it first comes into contact with the wear-resistant damping device 4. The material slides on the slide plate 401 and is protected by the initial wear-resistant plate 402, reducing direct wear on the chute body 1. Subsequently, the material is evenly distributed to different paths by the distribution plate 403, ensuring that the material is evenly distributed on the distribution plate 405. The linear alignment design of the distribution plate 403 allows the material to flow evenly along the inner circumference of the initial wear-resistant plate 402, avoiding material accumulation or gaps. At the same time, the distribution plate 405 is also linearly aligned along the inner wall of the middle wear-resistant plate 404, further ensuring the even distribution of the material. The baffle plate 1 406 and baffle plate 2 410 help guide the material to flow along the predetermined path and prevent the material from deviating from the distribution area. During the falling process, the material will sequentially come into contact with the discharge buffer plate 1 407 and the discharge buffer plate 2 411. These buffer plates are fixedly connected to the inner circumferential surface of the chute body 1 via buffer spring 409 and buffer spring 413, providing additional buffering effect. When material impacts the discharge buffer plate, the buffer spring absorbs part of the impact force, reducing the impact and wear of the material on the chute body 1. At the same time, the symmetrical distribution and linear array design of the discharge buffer plate 407 and discharge buffer plate 411 further enhance the buffering effect, ensuring efficient and stable material distribution.

[0036] like Figures 1-5 As shown, this invention illustrates a blast furnace charging chute in another embodiment, comprising: a dust adsorption device 7, which includes a connecting pipe 701 fixedly connected to the side of the chute body 1; a bellows 702 fixedly connected to the end of the connecting pipe 701 away from the chute body 1; a motor 703 fixedly connected to the inner wall of the bellows 702; a fan 704 fixedly connected to the output shaft of the motor 703; a slot 705 opened on the side of the bellows 702; a baffle plate 706 fixedly connected to the inner side of the chute body 1; and a reinforcing column 707 fixedly connected to the side of the bellows 702. Its function is to adsorb the large amount of dust generated when the material is delivered to the chute body 1, thereby reducing dust during charging, improving the quality of the working environment, and protecting the health of the operators.

[0037] In some examples, a protective plate 8 is fixedly connected to the side of the bellows 702, a filter plate 9 is inserted into the top of the bellows 702, and an inspection hole 10 is provided on the side of the bellows 702. A door panel 11 is provided on the inner wall of the inspection hole 10. The function of the protective plate 8 is to effectively protect the bellows 702 from impacts by external objects, thereby improving the safety and durability of the entire dust adsorption device 7. The insertion design of the filter plate 9 facilitates replacement and cleaning, ensuring smooth airflow inside the bellows 702.

[0038] The end of the reinforcing column 707 furthest from the bellows 702 is fixedly connected to the side of the chute body 1. Two reinforcing columns 707 and two motors 703 are provided, symmetrically distributed along the vertical central axis of the connecting pipe 701. Their function is to further enhance the structural strength and stability of the dust adsorption device 7. The reinforcing columns 707 effectively support the bellows 702 and motors 703, preventing them from shaking or vibrating during operation, thereby improving the stability and durability of the entire device.

[0039] The interior of the connecting pipe 701 penetrates the interior of the chute body 1. Several through slots are provided on the side of the protective plate 8 and are arranged linearly along the side of the protective plate 8. Their function is to facilitate air circulation and improve the adsorption efficiency of the dust adsorption device 7. The linear array design of the through slots ensures uniform air circulation, thereby improving the adsorption effect of the dust adsorption device 7.

[0040] For example, such as 1~ Figure 5 As shown, when the blast furnace is charging, the motor 703 starts, driving the fan 704 to rotate and generate suction. Air and dust are drawn into the bellows 702 through the connecting pipe 701. Inside the bellows 702, dust is intercepted and collected by the filter plate 9, while clean air is discharged through the channel on the side of the protective plate 8. Regular replacement and cleaning of the filter plate 9 ensures the continuous and efficient operation of the dust adsorption device 7. The baffle plate 706 effectively prevents material from directly entering the dust adsorption device 7, avoiding the risk of blockage or damage. The reinforcing column 707 not only enhances the structural strength of the dust adsorption device 7 but also ensures its stability during operation. Through the inspection hole 10 and the door plate 11, operators can easily inspect and maintain the components inside the bellows 702, improving the reliability and ease of use of the entire device. In summary, the blast furnace charging chute provided by this utility model, through the wear-resistant and shock-absorbing device 4 and the dust adsorption device 7, not only improves the efficiency and quality of charging but also...
