As important screening equipment, dewatering screens are widely used in coal, mineral processing, building materials, and other industries. The following is a comprehensive operation guide for dewatering screens from installation to commissioning:
1. Preparations before installation of dewatering screen
• Read the installation basis diagram: Read the installation basis diagram of the dewatering screen in detail to understand the overall structure and installation requirements of the equipment.
• Check the on-site conditions: Compare the basic installation diagram with the actual on-site conditions to ensure that the installation environment meets the equipment requirements.
• Embedded steel plate: Ensure that the flatness of the embedded steel plate is less than 3mm to ensure the overall stability of the screen.
2. Dewatering screen installation steps
• Installation sequence: Install the screen from bottom to top, ensuring that all parts are installed in place.
• Shock absorber spring and motor bracket: After installation is completed, adjust the relative positions so that the primary shock absorber spring and secondary shock absorber spring are perpendicular. Then weld the motor bracket, spring seat and embedded steel plate firmly.
• Motor installation: The vibration motor should be installed reliably and firmly on the vibration equipment to ensure that the motor and the vibration body are firmly connected.
• Cable fixation: After the motor is installed in place, the cable must not collide or rub with the vibrating body. They should be in a naturally suspended state and fixed to a fixed machine or frame.
3. Installation of dewatering screen body
• Screen selection: Select screens with the same mesh size to ensure screening accuracy and output.
• Place the screen: Place the screen flat on the pallet and level it, but do not use excessive force to avoid affecting the life and accuracy of the screen. Fasteners are then used to secure the screen to the grid.
• Tightening and inspection: Ensure that the periphery of the screen mesh is tightly pressed against the mother mesh frame. If there is any slack, adjust it appropriately.
4. Debugging and operation of the dewatering screen
• No-load test: First let the screen run without load for 4-6 hours, and observe whether the screen operates smoothly without deflection or abnormal noise. The amplitude difference between the left and right symmetry points should be less than 0.5mm.
• Adjust the exciting force: Adjust the exciting force according to the number of layers of the screen and the specific gravity of the material to achieve the best screening effect. Specific methods include removing the protective covers at both ends, loosening the compression bolts of the adjustable eccentric blocks at both ends, adjusting the position of the eccentric blocks tightening the bolts, etc.
• Feeding operation: After confirming that the screen is operating normally, you can start the feeding operation. When adding materials, the materials should be put in evenly to ensure that the materials are evenly distributed on the screen surface.
5. Maintenance and maintenance of the dewatering screen
• Regular inspection: Check the condition of the screen regularly and replace it if damaged. At the same time, check the insulation resistance of the vibration motor winding to the ground to ensure that the resistance is above 20MΩ.
• Clean up residues: After each shutdown, clean up residues inside and outside the equipment and keep the equipment clean.
Fastening bolts: Regularly check and tighten the bolts on the screen body and base to ensure the stability of the equipment operation.
6. Precautions for dehydration screen
• Safe operation: Wear protective glasses, gloves, and other protective equipment during operation to ensure personal safety.
• Avoid overloading: Avoid long-term overload operations to avoid damage to the equipment.
• Shutdown inspection: Before shutting down the equipment, do not leave any material on the screen surface to prevent the material from clogging the screen holes or damaging the screen mesh.
Through the above steps, you can ensure the smooth progress of the dewatering screen from installation to commissioning, and maintain good operating condition during subsequent use.
