Abstract
Description
Technical Field
[0001] This utility model belongs to the field of material conveying technology, specifically relating to an inertial dust suppression device for belt conveyors. Background Technology
[0002] In order to reduce dust pollution during the transfer process, belt conveyors usually install single-layer or double-layer belt covers near the discharge port. At the same time, a dust collection point is set up near the belt discharge port (downstream of the belt) and connected to the dust removal system through a pipeline.
[0003] The raw material dust removal system is responsible for many dust sources, and these sources may not operate at the same time. To reduce the system's energy consumption, electric valves are installed at each dust collection point. These electric valves are interlocked with the belt's operating status and the fan's operating frequency to achieve energy saving and consumption reduction.
[0004] As the operating frequency of the fan changes, the air velocity in the dust collection duct also changes. If the dust collection system operates for a long time under conditions deviating from the design conditions, dust will settle in the dust collection duct, reducing the effective flow area of the duct.
[0005] As dust settles in the branch pipes and main pipes, it disrupts the system resistance balance at each dust source, causing even more dust to settle.
[0006] After prolonged operation, the operating resistance of the dust removal system will increase, resulting in the actual operating air volume at each dust source point being lower than the designed air volume, poor dust removal effect at the belt conveyor station, and high operating costs. Summary of the Invention
[0007] This invention provides a belt conveyor inertial dust suppression device to address the shortcomings of existing technologies.
[0008] The technical solution of this utility model is: a belt conveyor inertial dust suppression device, including a belt sealing cover, which is installed on the conveyor belt, and a dust suction cover is provided above the belt sealing cover. A buffer section is provided between the belt sealing cover and the dust suction cover, and a dust suppression plate is provided in the buffer section. The dust suppression plate is welded inside the buffer section. The buffer section is connected to the belt sealing cover and the dust suction cover by bolts.
[0009] Furthermore, a dust suppression plate cleaning device is respectively installed on the upper or lower part of the buffer section.
[0010] Furthermore, the dust suppression panel is Z-shaped.
[0011] Furthermore, an observation hole is provided on the dust collection cover.
[0012] Dust generated during belt conveyor transport is contained inside the belt enclosure. The dust in the belt enclosure is then collected and treated through a buffer section, dust suppression plate, and dust collection hood via a dust removal pipeline.
[0013] Larger particles in the dust-laden gas collide with the dust suppression plate, causing them to settle freely on the conveyor belt. This effectively mitigates the risk of dust settling in pipelines and reduces wear and tear on pipes and fittings caused by dust.
[0014] The dust suppression panel cleaning system is located at the top or bottom of the buffer section. It uses compressed air to blow away the dust adhering to the surface of the dust suppression panel.
[0015] The dust suppression board is coated with abrasion-resistant material on both sides to increase its wear resistance.
[0016] The technical solution of this utility model is to effectively reduce the risk of dust settling in the pipeline due to changes in system operating conditions, while reducing dust wear on pipelines and fittings, reducing system resistance, reducing operating energy consumption, and achieving the effect of energy saving and carbon reduction.

[0020] The present invention will now be further described with reference to the accompanying drawings.
[0021] Figure 1 As shown, an inertial dust suppression device for belt conveyors includes a belt sealing cover 1, which is installed on the conveyor belt. A dust suction hood 4 is installed above the belt sealing cover 1. A buffer section 2 is provided between the belt sealing cover 1 and the dust suction hood 4. A dust suppression plate 3 is installed inside the buffer section 2. The buffer section 2 is connected to the belt sealing cover 1 and the dust suction hood 4 by bolts. An observation hole 5 is provided on the dust suction hood 4. The dust suppression plate 3 is Z-shaped.
[0022] Figure 2 As shown, the upper and lower sides of the buffer section 2 are connected to the belt sealing cover 1 and the dust collection cover 4 by flanges; the dust suppression plate 3 is welded inside the buffer section 2, and the sides of the dust suppression plate 3 are sprayed with wear-resistant material; the dust collection cover 4 is equipped with observation holes 5 on the side, and the upper and lower parts of the buffer section 2 are equipped with dust suppression plate cleaning devices 6.
[0023] Figure 1 , 2 As shown, the dust suppression plate 3 is installed inside the buffer section 2. The flow rate in the buffer section 2 is relatively low. When the dust-laden gas passes through the buffer section, larger particles collide with the dust suppression plate 3, causing the larger dust particles to settle freely on the conveyor belt. This effectively reduces the risk of dust settling in the pipeline due to changes in system operating conditions, and also reduces dust wear on the pipeline and fittings. The dust suppression plate cleaning device 6 cleans the dust adhering to the surface of the dust suppression plate 3 by blowing with compressed air.
[0024] Figure 2 As shown, the upper and lower sides of the buffer section (2) are connected to the belt sealing cover (1) and the dust collection cover (4) by flanges. The dust suppression plate (3) is welded inside the buffer section (2), and the sides of the dust suppression plate (3) are sprayed with wear-resistant material. The dust collection cover (4) has an observation hole (5) installed on the side, and the upper and lower parts of the buffer section (2) are equipped with dust suppression plates for cleaning (6).
