Technical Standards for Calcium Hydroxide Equipment Operation
Author:
To ensure the efficient and safe operation of calcium hydroxide equipment, each operator must strictly adhere to standardized operating procedures to avoid operational errors that may lead to decreased efficiency or safety hazards. The following key operating steps require special attention:
1. Equipment Installation and Securing: Calcium hydroxide equipment must be installed according to the specified installation procedures on a stable base. Before starting, use wooden wedges or braking devices to secure the wheels to prevent equipment movement. In environments with multiple equipment operating in parallel, a safety passage of at least one meter must be maintained between equipment and between equipment and walls to facilitate personnel passage and emergency evacuation.
2. Safety Inspection and Preparation: Before operation, thoroughly inspect the integrity of all operating parts, fasteners, and rolling bearings, and ensure that safety protection devices are complete and effective. At the same time, adjust the belt tension to an appropriate state to prepare for equipment startup.
3. No-load Test Run: The calcium hydroxide equipment should first be run without a load. Only after confirming stable and normal operation can materials be fed. It is strictly forbidden to start the equipment directly after feeding materials.
4. Startup Sequence: For multiple equipment operating in series, start from the discharge end and start in sequence to ensure that each equipment operates in coordination and stability before feeding.
5. Belt Deviation Handling: If belt deviation is found during operation, stop the machine immediately and adjust it to avoid forced operation causing belt edge wear and increased load.
6. Working Environment and Material Requirements: The operating environment temperature should be controlled above -50℃ and not lower than -10℃. It is strictly forbidden to convey materials containing strong acids, strong alkalis, oils, and organic solvents.
7. Personnel Safety: When the equipment is running, it is strictly forbidden to stand or carry passengers on the conveyor belt to ensure personnel safety.
8. Shutdown Operation: Before shutting down, stop feeding first, and only after the materials are completely unloaded can the equipment be shut down.
9. Electrical Safety: The motor of the calcium hydroxide equipment should maintain good insulation, and it is forbidden to drag the cable to ensure that the motor is reliably grounded to prevent electrical accidents.
10. Belt Adjustment Prohibition: When the belt deviates, it is strictly forbidden to pull the belt directly by hand to prevent accidents.
