Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices for car dumper, in particular to a dust removal device for train car dumper. Background Art

[0002] In recent years, raw fuel railway loading and unloading stations have been built outside the steel company's factory area. The main equipment of the loading and unloading station is the train car dumper, which is a highly efficient and highly automated device for unloading whole train carriages of raw fuel. A large amount of unorganized dust is generated during the loading and unloading process of the train car dumper, seriously polluting the environment. In the prior art, the train car dumper is arranged in the loading and unloading station workshop to form a closed space. Dust reduction pipes are arranged on the top and both sides of the loading and unloading station workshop, and dry (wet) spray dust reduction is carried out by using media such as water and carbon dioxide. For example, the dust removal device for car dumper in CN217920478U uses dry fog suppression with carbon dioxide, and a dust removal device for car dumper in CN213790711U is provided with a spray pipe, which is connected to a water pump and a water tank, and each spray pipe is connected to a plurality of atomizing nozzles. However, relying solely on dry (wet) spray dust reduction in the workshop cannot completely shield the smoke and dust, and some smoke and dust will still spill out of the workshop. In particular, when the train car dumper is tilted, within the surrounding area below the car dumper and above the receiving bin, due to space limitations, the situation of unorganized dust spillage is serious. Summary of the Utility Model

[0003] The utility model provides a dust removal device for train car dumper, which solves the problem of unorganized dust spillage within the surrounding area below the train car dumper and above the receiving bin due to space limitations.

[0004] To achieve this technical purpose, the utility model adopts the following scheme: A dust removal device for train car dumper includes a dust blocking net cover and a dust suction pipe. The dust blocking net cover is arranged behind the train car dumper, and the inner end of the dust suction pipe is connected with a dust suction hood. The dust suction hood is arranged on both sides inside the dust blocking net cover and in the space above the receiving bin.

[0005] Compared with the prior art, the beneficial effect of the utility model lies in that: The dust blocking net cover and the dust suction pipe are combined to form a closed space below the car dumper and above the receiving bin, and the dust suction pipe is used to guide and suck out the dust, effectively preventing the escape of unorganized dust.

[0006] Preferably, a guiding structure is arranged inside the dust blocking net cover. The guiding structure includes a guiding plate, a movable shaft and a motor. The guiding plate is an arc-shaped plate placed vertically, the guiding plate is fixedly connected with the movable shaft, and the movable shaft is connected with the output shaft of the motor. The angle of the guiding plate is adjusted by driving the movable shaft to rotate by the motor, effectively guiding the dust so that the dust flows towards the direction of the dust suction hood connected to the dust suction pipe, which is conducive to dust collection.

[0007] Preferably, the dust removal pipeline includes a main dust suction pipeline and side dust suction pipelines. The dust suction hoods of the side dust suction pipelines are located below the train dumper on both sides inside the dust blocking mesh hood. The dust suction hood of the main dust suction pipeline is located in the space in front of the train dumper and above the receiving bin. The diversion structure of the dust blocking mesh hood diverts the flying dust to both sides of the train dumper and is sucked out by the side dust suction pipelines. The flying dust generated at the receiving bin due to the downward turning of the train dumper is sucked out jointly by the main dust suction pipeline and the side dust suction pipelines, achieving good dust removal effect.

[0008] Preferably, a number of dust suction holes are arranged on the dust suction hoods to increase the dust suction area and optimize the dust collection effect for the flying dust in the space around the dust suction hoods.

[0009] Preferably, the number of the diversion structures is controlled within 1 to 3. Description of the Drawings

Detailed Embodiments

[0014] To fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0015] Such as Figure 1 and Figure 2As shown in the figure, a dust removal device for a train dumper provided by the utility model includes a dust-proof net cover 1, a dust suction pipeline and a dust suction hood. The dust-proof net cover 1 is arranged at the rear and sides of the train dumper 6, and the dust-proof net cover 1 wraps the rear and the left and right sides of the train dumper 6. The dust suction pipeline includes a main dust suction pipeline 3 and side dust suction pipelines 4. First dust suction hoods 5 are installed on the left and right sides of the train dumper 6. The first dust suction hoods 5 are located inside the dust-proof net cover 1, and the first dust suction hoods 5 are connected to the side dust suction pipelines 4. A second dust suction hood 10 is installed above the front of the train dumper 6 and above the receiving bin 9. The second dust suction hood 10 is communicated with the main dust suction pipeline 3. The position of the second dust suction hood 10 does not affect the normal operation of the train dumper 6. The main dust suction pipeline 3 and the side dust suction pipelines 4 are both connected to the main dust removal pipeline 2, and the main dust removal pipeline 2 is connected with a dust suction power structure such as a negative pressure fan. Preferably, a plurality of dust suction holes 7 are uniformly arranged on the first dust suction hood 5 and the second dust suction hood 10 to increase the dust suction area and optimize the dust collection effect for the dust floating in the space around the dust suction hood.

[0016] As Figure 3 shown, a diversion structure 8 is arranged at the rear of the dust-proof net cover 1. The diversion structure 8 includes a diversion plate 81, a movable shaft 82 and a motor 83. The movable shaft 82 is rotatably connected between the foundation platform and the dust-proof net cover 1. The diversion plate 81 is fixed on the movable shaft 82. The diversion plate 81 is an arc-shaped plate placed vertically. The upper end of the movable shaft 82 is connected to the output shaft of the motor 83, and the motor 83 can be installed at the upper end of the dust-proof net cover 1. When the motor 83 is started, it drives the movable shaft 82 to rotate, and then drives the diversion plate 81 to rotate, adjusts the angle of the diversion plate 81, changes the flow direction of the dust, and diverts the dust to the positions of the first dust suction hood 5 and the second dust suction hood 10, and discharges it through the dust suction pipeline. Preferably, the number of the diversion structures 8 is controlled within 1 to 3.

[0017] Working process:

[0018] Before the train dumper 6 starts to work, the angle of the diversion plate 81 is adjusted by using the motor 83. When the train dumper 6 starts to work, the main dust removal pipeline 2, the main dust suction pipeline 3 and the side dust suction pipelines 4 all suck the air and dust below the train dumper 6 and above the receiving bin 9 outwards, so that a relatively closed space is formed below the train dumper 6 and above the receiving bin 9, effectively preventing the escape of unorganized dust and achieving a good dust collection effect.

[0019] Finally, it should be noted that the above-listed are only the preferred embodiments of the present utility model. Of course, those skilled in the art can make changes and modifications to the present utility model. If these modifications and variations fall within the scope of the claims of the present utility model and its equivalent technologies, they should be considered as the protection scope of the present utility model.
