Description
Technical Field
[0001] This utility model relates to the field of raw material processing technology, specifically to a blast furnace vibration motor type environmental protection screen. Background Technology
[0002] The blast furnace vibrating motor-driven environmentally friendly screen is a key environmental protection device used for raw material pretreatment in the blast furnace ironmaking process. Powered by a vibrating motor, the screen vibrates to classify and screen blast furnace feed materials (such as iron ore, coke, and sinter), separating materials that meet the particle size requirements for blast furnace smelting. This prevents large impurities or unevenly sized materials from entering the blast furnace and affecting smelting efficiency. Simultaneously, its environmentally friendly structure controls dust generated during screening, reducing dust pollution and health hazards to workers. It is suitable for pretreatment before feeding into the blast furnace feed silo, providing qualified raw materials for stable, efficient, and environmentally friendly blast furnace smelting.
[0003] Traditional vibrating motor-driven screening equipment for blast furnaces suffers from significant shortcomings in balancing dust suppression and material protection. Most equipment lacks a dedicated atomizing dust suppression structure or relies solely on simple spraying. Without dust suppression, the large amount of dust generated from screening raw materials will diffuse into the workshop environment, polluting the air, corroding equipment, and damaging the respiratory system of workers. If ordinary spraying is used, the water flow cannot be atomized, resulting in either limited spraying area with dust suppression dead zones or excessive water volume that wets the raw materials, leading to excessive moisture content. This can cause problems such as water carryover in the blast furnace gas and furnace temperature fluctuations, affecting smelting stability. Furthermore, existing dust suppression equipment typically has fixed nozzles that cannot flexibly adjust the spray angle, making it difficult to cover the entire screen area and resulting in poor dust suppression. Moreover, it lacks a precise drive adjustment structure, making it impossible to adjust the spray range according to dust generation or screen vibration. This fails to achieve comprehensive dust suppression and may lead to material dampness due to excessive local spraying, thus failing to meet the dual requirements of blast furnace production for "efficient dust suppression, environmental compliance, and material quality preservation." Therefore, we propose a blast furnace vibrating motor-driven environmental protection screen. Utility Model Content
[0004] One of the technical problems this application aims to solve is that existing raw material handling devices lack specialized atomization dust suppression structures, which cannot meet the dual requirements of blast furnace production for efficient dust suppression, environmental compliance, and material quality preservation.
[0005] To address the aforementioned technical problems, this application provides a blast furnace vibrating motor-type environmental protection screen, comprising a shell, a fixed plate on one side of the upper end of the shell, a motor body fixedly connected to the fixed plate, a rotating block connected to the lower end of the motor body, a limit groove formed on the rotating block, a sleeve movably connected to the outer wall of one side of the lower end of the motor body, a first connecting rod fixedly connected to each of the outer walls of both sides of the sleeve, a first collar fixedly connected to the lower outer wall of the first connecting rod, a crossbar fixedly connected to one side of the inner wall of the first collar, a second collar movably connected to one side of the outer wall of the crossbar, a second connecting rod fixedly connected to one side of the outer wall of the second collar, a movable block movably connected to one side of the outer wall of the second connecting rod, and a limit rod fixedly connected to the upper outer wall of the movable block.
[0006] In some embodiments, a water tank is provided on one side of the upper inner wall of the housing, a screen is connected to one side of the upper inner wall of the housing, a collection device is fixedly connected to one side of the outer wall of the housing, a fixing block is fixedly connected to both sides of the outer wall of the housing, a shock-absorbing spring is connected to the lower end of the fixing block, a bracket is fixedly connected to both sides of the outer wall of the fixing block, and a driving device is provided on one side of the upper end of the bracket.
[0007] In some embodiments, a third fixing rod is fixedly connected to the outer wall of the lower end of the second collar, a fixing member is fixedly connected to the middle of the third fixing rod, a nozzle is movably connected to one side of the inner wall of the fixing member, and a water pipe is movably connected to the upper end of the nozzle.
[0008] In some embodiments, a limiting rod provided on the outer wall of the upper side of the movable block is correspondingly connected to a limiting groove opened on the rotating block.
[0009] In some embodiments, the lower end of the nozzle is connected to the upper end of a screen provided on one side of the inner wall of the housing.
[0010] In some embodiments, a water pipe located on one side of the upper end of the nozzle is connected to a water tank located on one side of the inner wall of the upper end of the housing.
[0011] In some embodiments, a collecting device provided on one side of the outer wall of the housing is correspondingly connected to a screen provided on one side of the inner wall of the housing.
[0012] In some embodiments, the motor body is disposed on the outer wall of the upper side of the fixing plate, and the lower end of the motor body extends to the lower side of the fixing plate and is fixedly connected to the rotating block.
[0013] This utility model has at least the following beneficial effects: In use, the core of this invention lies in the atomizing dust suppression structure, which consists of a motor body, a rotating block, a limiting rod, a movable block, a second ring, a nozzle, a water pipe, and a water tank. The motor body drives the rotating block to rotate, which in turn causes the limiting rod to shift via a limiting groove. The limiting rod then pulls the movable block to move laterally back and forth on the second connecting rod, simultaneously causing the second ring to rotate along the crossbar, ultimately achieving multi-angle adjustment of the nozzle. The nozzle is connected to the water tank via a water pipe, allowing for precise spraying of atomized water onto the screen below. This quickly suppresses dust during screening, preventing environmental pollution and comprehensively protecting the health and safety of workers. The multi-angle adjustable spray design ensures thorough dust suppression, and the atomized spray guarantees effective dust suppression without excessively wetting the material, thus avoiding any negative impact on screening quality. In use, this invention utilizes a vibration and damping system comprised of a drive unit, fixed blocks, damping springs, and a support frame to ensure stable vibration power for the screening operation, guaranteeing efficient separation of materials on the screen. The fixed blocks on both sides of the casing, in conjunction with the damping springs, buffer the impact of vibration, providing overall shock protection and reducing component wear. This also effectively reduces noise from vibration, improving the comfort of the working environment and solving the problems of severe vibration and harsh noise in traditional screening devices. In use, the auxiliary structure consisting of a collection device and a sleeve enhances operational convenience and structural reliability. The collection device is connected to the screen, directly collecting the screened material and preventing material scattering that would increase subsequent cleaning workload, thus improving operational efficiency. The sleeve, fitted around the output end of the motor body, provides limiting protection, preventing damage to the output end due to screening vibration or material collision, and extending the service life of the motor and related transmission components. Furthermore, the flexible connection of various transmission components (such as the second collar and crossbar, the movable block and the second connecting rod) ensures smooth nozzle angle adjustment and coordinated operation with the vibrating screening action, further enhancing the overall operational stability of the device. It is suitable for screening operations in various scenarios, including ores and granular raw materials. Attached Figure Description

[0017] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a blast furnace vibrating motor type environmental protection screen, including a shell 1, a fixing plate 2 on one side of the upper end of the shell 1, a motor body 3 fixedly connected to the fixing plate 2, a rotating block 4 connected to the lower end of the motor body 3, the motor body 3 being located on the outer wall of one side of the upper end of the fixing plate 2, the lower end of the motor body 3 extending to one side of the lower end of the fixing plate 2 and fixedly connected to the rotating block 4, a limit groove 5 being provided on the rotating block 4, a sleeve 6 being movably connected to the outer wall of one side of the lower end of the motor body 3, a first connecting rod 7 being fixedly connected to each of the outer walls of both sides of the sleeve 6, a first collar 8 being fixedly connected to the lower outer wall of the first connecting rod 7, and a first collar 8 being fixedly connected to the inner wall of the first collar 8. A horizontal bar 9 is fixedly connected to the side. A second ring 10 is movably connected to the outer wall of one side of the horizontal bar 9. A second connecting rod 11 is fixedly connected to the outer wall of the upper end of the second ring 10. A movable block 12 is movably connected to the outer wall of one side of the second connecting rod 11. A limit rod 13 is fixedly connected to the outer wall of the upper end of the movable block 12. The limit rod 13 on the outer wall of the upper end of the movable block 12 is correspondingly connected to the limit groove 5 opened on the rotating block 4. A third fixing rod 14 is fixedly connected to the outer wall of the lower end of the second ring 10. A fixing member 15 is fixedly connected to the middle of the third fixing rod 14. A nozzle 16 is movably connected to one side of the inner wall of the fixing member 15. A water pipe 17 is movably connected to the upper end of the nozzle 16.
[0018] In this embodiment, a housing 1 is designed, with a fixing plate 2 connected to one side of the inner wall of the housing 1. Multiple motor bodies 3 are mounted on the fixing plate 2. An output end of one side of the lower end of each motor body 3 extends to the lower end of the fixing plate 2 and is fixedly connected to a rotating block 4. A sleeve 6 is connected to one side of the outer wall of the output end, serving as a limiting protection. A limiting groove 5 is formed on one side of the rotating block 4. A first collar 8 is fixedly connected to both sides of the sleeve 6 via a first connecting rod 7. A crossbar 9 is fixedly connected to one side of the inner wall of the first collar 8. A second ring 10 is movably connected to one side of the outer wall of ring 9 and one side of the inner wall of the first ring 8. A second connecting rod 11 is fixedly connected to the upper end of the second ring 10. A movable block 12 is movably connected to one side of the upper outer wall of the second connecting rod 11. A limiting rod 13 is fixedly connected to the upper outer wall of the movable block 12. The limiting rod 13 can be connected to the limiting groove 5 opened on the rotating block 4. A fixing member 15 is fixedly connected to the lower end of the second ring 10 through a third fixing rod 14. A nozzle 16 is movably connected to one side of the inner wall of the fixing member 15. The upper end of the nozzle 16 is connected to... There is a water pipe 17, the other side of which can be connected to a water tank 18 located on the upper side of the housing 1. Therefore, when the motor body 3 is started, the motor body 3 will drive the rotating block 4 to rotate. At this time, the rotating block 4 will drive the limiting rod 13 to shift through the limiting groove 5. The limiting rod 13, under the action of the limiting groove 5, will drive the movable block 12 to shift laterally back and forth on the second connecting rod 11. At the same time as the shift, the limiting rod 13 will undulate on one side of the inner wall of the limiting groove 5, so as not to affect the shift of the movable block 12 on the second connecting rod 11. Thus, the second connecting rod 11 can drive the second ring 10 to rotate on the outer wall of the crossbar 9, thereby causing the nozzle 16 connected to the fixing member 15 on one side of the third fixing rod 14 at the lower end to shift in angle. The nozzle 16 is connected to the water tank 18 through the water pipe 17, which can atomize and spray water. A screen 19 is connected to the lower end of the nozzle 16. Therefore, a large amount of dust will be generated when the device is screening. In order not to pollute the environment, the nozzle 16 can spray water mist onto the screen 19, thereby solving the dust problem and ensuring the health and safety of the staff.
[0019] Example 2: Please refer to Figure 1-2A water tank 18 is provided on one side of the upper inner wall of the housing 1. A water pipe 17 is provided on one side of the upper end of the nozzle 16 and is correspondingly connected to the water tank 18 provided on one side of the upper inner wall of the housing 1. A screen 19 is connected to one side of the upper inner wall of the housing 1. The lower end of the nozzle 16 is correspondingly connected to the upper end of the screen 19 provided on one side of the inner wall of the housing 1. A collection device 20 is fixedly connected to one side of the outer wall of the housing 1. The collection device 20 provided on one side of the outer wall of the housing 1 is correspondingly connected to the screen 19 provided on one side of the inner wall of the housing 1. A fixing block 21 is fixedly connected to both sides of the outer wall of the housing 1. A shock-absorbing spring 22 is connected to the lower end of the fixing block 21. A bracket 23 is fixedly connected to both sides of the outer wall of the fixing block 21. A driving device 24 is provided on one side of the upper end of the bracket 23.
[0020] In this embodiment, a collecting device 20 is provided on one outer wall of the housing 1, which is connected to a screen 19 on one inner wall of the housing 1. The material screened by the screen 19 can be collected. Fixing blocks 21 are provided on both outer walls of the housing 1, and shock-absorbing springs 22 are connected to the lower ends of the fixing blocks 21. Supports 23 are provided on both outer walls of the housing 1, and a driving device 24 is provided on the upper outer wall of the support 23. Therefore, the driving device 24 can drive the device 24 to vibrate, thereby performing the screening function. The shock-absorbing springs 22 can provide shock absorption and protection for the device, and also reduce noise, making the working environment comfortable. The driving device 24 relies on a vibrating motor to achieve vibration. An eccentric block is installed at the end of its motor shaft. Usually, two identical vibrating motors rotate synchronously in opposite directions. When the eccentric block rotates, it generates centrifugal inertial force to form an excitation force, which in turn drives the screen body to perform periodic reciprocating vibration along the direction of the excitation force. Since the operation of the driving device 24 is existing technology, it will not be described in detail.
