Description

Technical Field

[0001] This utility model relates to the field of solid material conveyor belt technology, specifically a self-dust-removing, non-powered material guide trough. Background Technology

[0002] Belt conveyors are a common material conveying equipment widely used in industries such as metallurgy, coal, transportation, power, building materials, chemicals, light industry, grain, and machinery. During the conveying process, there are multiple transfer points, where the upper belt transports material to the lower belt. As the material falls, it generates a large amount of dust-laden airflow, which is released into the feed chute, causing dust spraying and pollution around the feed chute, severely polluting the environment. Typically, dust removal equipment is installed at the feed chute outlet and the drop point to address this, but this method is energy-intensive, has high maintenance costs, and its efficiency decreases after prolonged operation, resulting in unsatisfactory dust removal effects.

[0003] Therefore, it is necessary to provide a self-dust-removing, non-powered material guide trough to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a self-dust-removing, non-powered material guide trough.

[0005] This utility model provides a self-dust-removing, non-powered material guide chute, comprising a column, side plates, a cover plate, a tail sealing box, an outlet damping curtain, a damping dust suppression box, a dust curtain, a double-sided support plate assembly, a primary circulating pressure reducing device, a secondary circulating pressure reducing device, and a suspended self-dust-removing skirt. The column is installed on the intermediate frame of the on-site belt conveyor. The side plates and the cover plate form a protective cover installed on the column. The tail sealing box and the outlet damping curtain are respectively installed at both ends of the protective cover. Damping dust suppression boxes are installed at intervals on the cover plate, and dust curtains are suspended inside the damping dust suppression boxes. The primary circulating pressure reducing device and the secondary circulating pressure reducing device are installed on the cover plate. The double-sided support plate assembly is installed on both sides of the idler roller group of the on-site belt conveyor. The suspended self-dust-removing skirt is fixed to the side plate with a gap between it and the surface of the conveyor belt of the belt conveyor.

[0006] Preferably, the double-sided tray assembly is a hollow board.

[0007] Preferably, the column, side plate and cover plate are all fixed by bolts.

[0008] Preferably, both the primary circulation pressure reducing device and the secondary circulation pressure reducing device are V-shaped pipelines.

[0009] Preferably, the double-sided pallet assembly is at a 35-degree angle to the horizontal plane.

[0010] Compared with related technologies, the present invention provides the following beneficial effects:

[0011] 1. By setting up a damping device and a multi-stage circulation pressure reduction device above the feed chute, the aerodynamic principle is used to guide circulation and block airflow, thus forming an automatic dust reduction and elimination system.

[0012] 2. The skirt board adopts a suspended self-dust-removing skirt edge. Through its own structure, it generates inward airflow during the operation of the belt conveyor, which further prevents dust from overflowing. Compared with the skirt board that is in direct contact with the belt, it has less wear and requires less maintenance in the later stage.

[0013] 3. Double-sided rectangular pallet assemblies are installed between standard idler roller groups to avoid dust overflow caused by the wavy operation of the belt. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figures 1 to 3 A self-dust-removing, non-powered material guide chute includes a column 1, side plates 2, a cover plate 3, a tail sealing box 4, an outlet damping curtain 5, a damping dust suppression box 6, a dust curtain 7, a double-sided support plate assembly 8, a primary circulation pressure reducing device 9, a secondary circulation pressure reducing device 10, and a suspended self-dust-removing skirt 11. The column 1 is securely mounted on the intermediate frame of the on-site belt conveyor, providing support for the entire material guide chute. The side plates 2 and the cover plate 3 together form a protective cover, bolted together, which is firmly installed on the column 1. At both ends of the cover, the tail sealing box 4 and the outlet damping curtain 5 are installed respectively, each performing the important functions of sealing and damping.

[0020] Multiple damping dust suppression boxes 6 are also installed at intervals on the cover plate 3, and each damping dust suppression box 6 has a dust curtain 7 suspended inside. These designs are all for the purpose of more effectively suppressing the spread of dust. At the same time, the primary circulation pressure reduction device 9 and the secondary circulation pressure reduction device 10 are also cleverly installed on the cover plate 3, which together constitute a multi-stage circulation pressure reduction system. This system plays a key role in controlling the airflow and dust in the feed chute;

[0021] The double-sided pallet assembly 8 is another important design element, installed on both sides of the idler group of the on-site belt conveyor. This assembly is made of hollow sheet material and is angled at 35 degrees to the horizontal plane, which not only provides stable support for the belt but also effectively prevents the belt from wavy movement.

[0022] Of particular note is the design of the suspended self-cleaning skirt 11, which is fixed to the side plate 2 and maintains a certain gap with the surface of the conveyor belt. This design creates a pressure difference between the inside and outside of the suspended self-cleaning skirt 11 during the operation of the conveyor belt, generating an inward airflow and creating a negative pressure suction state. This negative pressure suction effect effectively draws the dust generated during transportation into the inside, preventing it from overflowing into the environment.

[0023] When bulk materials fall from the upstream belt conveyor, the tail sealing box 4 seals tightly, ensuring that the dust-laden airflow moves in the direction of the belt conveyor. The airflow first passes through the primary circulating pressure reducing device 9, where the dust curtain 7 blocks the airflow, causing it to circulate within the device and creating a counteracting force, thus achieving pressure balance. Subsequently, the airflow continues through the damping dust suppression box 6, where multiple dust curtains 7 adsorb the passing dust, causing a large amount of dust to clump together and automatically detach under the disturbance of the material flow, being carried away with the material flow. Finally, when passing through the secondary circulating pressure reducing device 10, the airflow that was not treated by the primary circulating pressure reducing device 9 is further processed until it reaches the outlet, thus achieving the purpose of thorough dust removal.

[0024] Furthermore, the tail sealing box 4 adopts a three-stage sealing design, which further ensures that dust-laden gas will not overflow from the tail of the guide chute during material transportation. The double-sided pallet assembly 8 is made of corrosion-resistant, wear-resistant, and low-friction coefficient high-molecular-weight polyethylene material, which not only provides excellent support for the belt but also effectively extends its service life.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
