Description

Technical Field

[0001] The present application relates to the field of coking and metallurgical production, and in particular to a sealing device for a train unloading area of ​​a steel plant or a coking plant. Background Art

[0002] In the train unloading area of ​​steel mills or coking plants, the main reason for dust generation is that the materials (such as coal, coke, ore, etc.) are subjected to external forces during the unloading process, causing fine particles to separate from the main materials and enter the surrounding environment. Usually, in the unloading area, there are many reasons for dust. For example, when the materials in the train carriage are unloaded, they fall from a higher position into the funnel or conveyor belt, which generates a large impact force, causing dust to fly. The greater the height difference, the stronger the impact, and the more obvious the dust diffusion. In addition, most of the materials in steel mills and coking plants are powdered or granular. The smaller and drier the particles are, the easier they are to float in the air. In particular, dry coal powder and coke powder are easy to disperse and form dust due to static electricity or friction. At the same time, it is also related to the loading and unloading speed. When the unloading speed is fast, the material fluidity is large, and dust is easy to be generated at the contact point. In addition, the flow of air, the transportation method of materials, changes in temperature and humidity, etc., will affect the dust in the unloading area.

[0003] Therefore, for the train unloading area of ​​a steel plant or coking plant, a sealing device needs to be installed. The sealing device is to reduce the dust and gas leakage during the unloading process to ensure the safety of the working environment and reduce environmental pollution. These sealing devices are usually used to close the unloading area and cooperate with the dust removal system to effectively capture the generated dust and harmful gases. In the related technology, a flexible sealing device, a hard sealing device, a movable sealing device, a sealing compartment or a sealing cover is usually set to seal the unloading area.

[0004] However, in the actual working process of a steel plant or a coking plant, multiple trains are generally used to transport materials such as raw coal or coke. During the transportation process, the train is fully enclosed with work cloth. The unloading area generates more dust during the unloading process and needs to be closed. However, each train carriage needs to be driven by a tractor to enter the unloading area. Since most tractors are electric locomotives, the power source relies on a row of electric sliding wires. The electric sliding wires run through the entire unloading area. Due to the interference of the sliding wires, the unloading area cannot be sealed, and the purpose of dust control cannot be achieved. The train inlets and outlets in the existing unloading area cannot be sealed, resulting in the dust generated during the unloading process still being able to diffuse into the air. There has been no good solution to the above problems. Therefore, there is an urgent need for a sealing device for the unloading area of ​​a train in a steel plant or a coking plant to solve the above problems. Summary of the invention

[0005] In order to solve the problem that the train inlet and outlet in the existing unloading area cannot be sealed, resulting in the dust generated during the unloading process still being able to diffuse into the air, the present application provides a sealing device for the train unloading area of ​​a steel plant or a coking plant.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 and Figure 2 This application is described in further detail.

[0031] The embodiment of the present application discloses a sealing device for a train unloading area of ​​a steel plant or a coking plant.

[0032] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] Here, it is necessary to further explain in detail the background of the present application. In the actual working process of a steel plant or a coking plant, although there may be technologies similar to the present solution in the relevant technologies, these solutions may be able to seal the unloading area to a certain extent, but it is difficult to meet the current environmental protection requirements. Therefore, the inventive concept and inventive solution of the present application have overcome technical prejudice to a large extent, and these technical personnel in this field can also understand it.

[0034] Reference Figure 1 and Figure 2 A sealing device for a train unloading area of ​​a steel plant or a coking plant comprises a sealing component 1 and a power-taking regulating mechanism 2. The sealing component 1 can seal and isolate the inlet and outlet of the unloading area, so that the unloading area is effectively isolated from the outside. The use process is that a tractor 3 tows a train loaded with goods to move, and the power-taking regulating mechanism 2 on the tractor 3 will adjust the state of the sealing component 1. After the tractor 3 drives the train carriage to the designated unloading area, under the action of the power-taking regulating mechanism 2, the sealing component 1 can seal the unloading area, so that during the unloading process, dust pollution to the air can be reduced, which is safe and environmentally friendly. The present application solves the problem that the inlet and outlet of the train in the existing unloading area cannot be sealed to a certain extent, resulting in the dust generated during the unloading process still being able to diffuse into the air.

[0035] Specifically, in the embodiment of the present application, the sealing assembly 1 is arranged at the entrance and exit of the unloading area, that is, the sealing assembly 1 can seal both the entrance and exit of the unloading area to prevent the leakage of dust and reduce pollution to the environment.

[0036] More specifically, in the embodiment of the present application, the sealing assembly 1 includes a first rolling shutter door 11 and a second rolling shutter door 12. The first rolling shutter door 11 is arranged at the entrance of the unloading area, and the second rolling shutter door 12 is arranged at the exit of the unloading area. In other embodiments, movable baffles, flexible curtains, and inflatable seals can also be used as components of the sealing assembly 1, which are also embodiments that can be implemented in the present application.

[0037] The provision of the first rolling door 11 and the second rolling door 12 not only ensures effective closure, but also can be quickly opened when not in use, facilitating the smooth entry and exit of materials and the passage of vehicles. Compared with other sealing components, the rolling door can be used for a longer period of time.

[0038] Furthermore, the first rolling door 11 and the second rolling door 12 are both provided with a clearance groove 6 at one end close to the track of the tractor 3 and the track of the train carriage.

[0039] The clearance groove 6 can provide enough space for the rails when the shutter door is sealed to avoid friction with the car body, ensuring that the shutter door is not hindered by the train body when sealing, ensuring the sealing effect, and protecting the shutter door and the car body from wear and tear.

[0040] Furthermore, a sealing rubber is arranged on the outer side wall of the groove. It should be noted that, for the sake of convenience, the sealing rubber is not specifically shown in the drawings of the present specification, which should be easy to understand for those skilled in the art.

[0041] The sealing rubber can provide a further sealing effect to prevent external dust from entering the discharge area.

[0042] In the present application, further explanation of the busbar 4 and the tractor 3 is required. For those skilled in the art, the busbar 4 is an electrical device specially designed for powering mobile devices or transmitting signals. The busbar 4 transmits electrical energy or signals to the mobile devices through conductive rails to achieve continuous power supply or control of the devices. In the embodiment of the present application, it specifically refers to the power supply and control of the tractor 3. The tractor 3 is a means of transport specially used for dragging, pushing or pulling goods, equipment, vehicles, etc., and is widely used in special occasions such as industry, logistics, ports, etc. In the embodiment of the present application, the tractor 3 specifically refers to a train carriage for towing and transporting materials.

[0043] Specifically, the power-taking adjustment mechanism 2 is used to control the sealing state of the sealing assembly 1 . The power-taking adjustment mechanism 2 is electrically connected to the sealing assembly 1 . The power-taking adjustment mechanism 2 is disposed on the tractor 3 .

[0044] Furthermore, the power taking and regulating mechanism 2 includes a first rotating assembly 21 and a second rotating assembly 22 , and both the first rotating assembly 21 and the second rotating assembly 22 are rotatably connected to the tractor 3 .

[0045] This ensures that the device has strong adaptability when sealing, is easy to operate, and simplifies the sealing control process.

[0046] Furthermore, the first rotating assembly 21 includes a first rotating rod 211 and a first driving member 212. The first rotating rod 211 is hinged on the tractor 3. The first driving member 212 is arranged on the tractor 3 and is arranged away from the hinge point of the first rotating rod 211. A busbar 4 is arranged on the unloading area frame. The first rotating rod 211 can interfere with the busbar 4, and the busbar 4 is electrically connected to the first rotating rod 211.

[0047] The rotating rod is connected to the busbar 4 and is controlled by a drive so that it can automatically adjust to the busbar 4 to ensure connection with the power system. This design uses the busbar 4 to transmit electricity, which not only provides stable power support, but also improves the convenience of control and reduces the complexity of manual operation.

[0048] At the same time, the second rotating component 22 is located on the tractor 3 and is arranged away from the first rotating component 21. The second rotating component 22 includes a second rotating rod 221 and a second driving member 222. The second rotating rod 221 is hinged on the tractor 3, and the second driving member 222 is arranged on the tractor 3 and away from the hinge point of the second rotating rod 221. The second rotating rod 221 can abut against the busbar 4, and the busbar 4 is electrically connected to the second rotating rod 221.

[0049] The second rotating assembly 22 is arranged away from the first rotating assembly 21, so that the two rotating assemblies act on different positions of the unloading area respectively, so as to ensure bidirectional control of the sealing device.

[0050] Further, in the embodiment of the present application, the first driving member 212 and the second driving member 222 are both oil cylinders. In other embodiments, cylinders can also be used as the first driving member 212 and the second driving member 222, which is also a preferred embodiment of the present application.

[0051] The application of the oil cylinder makes the entire sealing adjustment process smoother and improves the durability and stability of the device, maintaining reliable performance in high-frequency operations.

[0052] Further, the busbar 4 is disconnected at both the first rolling door 11 and the second rolling door 12. The busbar 4 is disconnected at the first rolling door 11 and the second rolling door 12 to prevent the busbar 4 from being disturbed by the rolling doors.

[0053] Furthermore, a flexible busbar 5 is provided between the busbar 4 and the first rolling door 11 and between the busbar 4 and the second rolling door 12. The flexible busbar 5 can adapt to different position changes when the rolling door moves.

[0054] In combination with the foregoing content, the operating logic of the power supply regulating mechanism 2 of the present application is specifically explained: a first rotating component 21 and a second rotating component 22 are arranged on the tractor 3, and before the tractor 3 enters the unloading area, the first rotating component 21 is connected to the busbar 4 to supply power to the tractor 3, and before the tractor 3 enters the unloading area and the first rotating component 21 is disconnected from the busbar 4, the second rotating component 22 is connected to the busbar 4, and then the second rotating component 22 disconnects the busbar 4, and the tractor 3 drives the train car to the designated position and then exits the unloading area. In this process, the second rotating component 22 is connected to the busbar 4 before the first rotating component 21 is disconnected from the busbar 4, and then the first rotating component 21 is disconnected from the busbar 4. After the tractor 3 completely exits the unloading area, the rolling door is closed, and then the material in the train car can be unloaded.

[0055] The implementation principle of a sealing device for a train unloading area of ​​a steel plant or a coking plant in an embodiment of the present application is as follows: the sealing device of the present application is configured as a combination of a sealing component 1 and a power adjustment mechanism 2, so that when unloading goods from the steel plant or the coking plant, the sealing adjustment component is adjusted simultaneously with the change in the moving position of the tractor 3, thereby achieving sealing of the unloading area by the sealing component 1, effectively preventing the leakage of dust, and the power adjustment mechanism 2 of the present application moves with the tractor 3, ensuring the real-time and flexibility of the seal, and enhancing the automation and sealing effect of the sealing device. The present application solves to a certain extent the problem that the train inlet and outlet in the existing unloading area cannot be sealed, resulting in the dust generated during the unloading process still being able to diffuse into the air.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
