When long-deactivated organic fertilizer equipment is used again, a series of inspections and maintenance are required to ensure that the equipment can operate normally and extend its service life. Here are some key steps and considerations:

1. Check the environment: Ensure that the storage area of the device is dry and well-ventilated to avoid excessive dust, which may affect the device performance. For equipment parked outdoors, take moisture-proof measures, such as covering with a tarp or moving it indoors for storage.

2. Exterior and internal inspection: Check whether the equipment has rust, cracks or other visible damage. Clean equipment thoroughly to prevent them from causing corrosion or clogging over a long period of time. All moving parts are properly lubricated to prevent rust and dryness.

3. Electrical system inspection: Ensure that all power supplies have been safely cut off, and take measures to avoid accidental power-on. Check whether all internal lines and gas pipe connectors of the device are loose to avoid air leakage and poor contact.

4. Mechanical parts inspection: check whether the locking screws of each part are loose to eliminate safety hazards in time. For parts prone to moisture, apply anti-rust oil or other anti-corrosion measures.

5. Test operation: Every once in a while, the equipment should be manually or automatically started to test to check whether the equipment can operate normally. Before the equipment is about to be put into use again, a series of review procedures must be carried out, including safety checks, functional tests, etc., to confirm that the organic fertilizer production line meets the operational standards.

Through the above steps, you can effectively ensure that the equipment that has been disabled for a long time can operate normally when it is used again, reducing the production interruption and maintenance costs caused by equipment failure.
