Introduction to Dust - proof and Rain - proof Covers for Conveyors
Dust - proof and rain - proof covers for conveyors are important equipment used to protect conveyors and the materials being transported. Here is a detailed introduction:
Functions
- Protect Equipment and Materials: Effectively block rainwater and dust. Prevent conveyors from rusting and being damaged due to rainwater erosion, and avoid materials from getting wet by rain, which could lead to deterioration or loss. This reduces the loss of goods during the conveying process. For example, in a cement factory, it prevents cement from getting damp and caking; in a mine, it avoids ore being washed away by rainwater.
- Enhance Operational Safety: Reduce equipment failures caused by rainwater, dust, etc., such as slipping and motor short - circuits. This makes the conveyor belt run more safely and reliably, ensuring the continuity of production.
- Environmental Protection and Energy Conservation: Prevent dust from flying and spreading, reducing environmental pollution and meeting environmental protection requirements. Also, it cuts down on economic costs and resource waste resulting from material loss.
Structure and Materials
- Structure: Most are designed in an arch or arc shape, which can effectively drain water and reduce water accumulation. They are usually assembled from multiple cover bodies. Some have openable covers at regular intervals, facilitating equipment inspection, maintenance, and material inspection.
- Materials: Common materials include color - coated steel plates, galvanized steel plates, stainless steel plates, and fiberglass reinforced plastics. Color - coated steel plates are cost - effective and come in various colors; galvanized steel plates have good anti - corrosion properties; stainless steel plates are high - strength, corrosion - resistant, and have a long service life, but are relatively costly; fiberglass reinforced plastics are lightweight, high - strength, and highly corrosion - resistant.
Application Scope
They are widely used in conveyor systems in power plants, cement plants, coal mines, steel mills, chemical plants, ports, docks, and other places. For example, in the coal - conveying belts of power plants, the bulk material transportation in cement plants, and the ore transportation in coal mines.
Installation and Maintenance
- Installation: First, weld connecting angle steels or Z - shaped steels on both sides of the conveyor frame as the skeleton. Install the rain - proof covers from one end of the frame to the other. Avoid standing on or hitting the covers during installation. Fix the rain - proof covers to the skeleton with hook nails or self - tapping screws, with no less than 4 fixing points for each cover. Lap the corrugations as required and install openable covers at regular intervals.
- Maintenance: Regularly check the fixing condition of the rain - proof covers. Tighten them promptly if they are loose. Clean the dust and debris on the surface of the covers to ensure smooth drainage. Check for any damage or corrosion on the covers and repair or replace the damaged parts in a timely manner.
