Overview
Granular material silo is mainly used for the storage and transfer of granular materials. It is a key equipment for efficient material management in industrial production lines.The components of the granular material silo include: silo body, climbing ladder, guardrail, feeding pipe, dust collector, pressure safety valve, high and low level indicators, discharge valve, etc. These parts work together to ensure the stable operation of the granular material silo.A pressure safety valve is designed on the dust collector at the top of the granular material silo, which effectively prevents accidents and ensures the safe use of the equipment for manufacturers and production lines.With a high-pressure fan, the granular materials entering the hopper are transported to the storage barrel for storage, and when needed, the materials are discharged through the material outlet—this process realizes efficient material circulation for industrial production needs.The granular material silo is sturdy and durable, with anti-rust and anti-corrosion treatment applied inside and outside the silo body, which extends the service life of the granular material silo and reduces maintenance costs for enterprises.Users (including factory managers, production line engineers, and procurement personnel) can determine the structure type of the granular material silo according to their usage requirements. According to actual needs, various accessories such as mixers, screens, and level indicators can be optionally equipped for the granular material silo to meet personalized production demands.
Maintenance of Granular Material Silo:
- In the first 7 days after the installation of the granular material silo, it is necessary to check the foundation for settlement every day; after filling the silo with granular materials, the foundation settlement must be checked regularly. This ensures the stable operation of the granular material silo and prevents safety hazards caused by foundation problems.
- Before filling the granular material silo with granular materials for the first time, the residual debris in the silo must be cleaned up to prevent it from mixing into the powder, which may cause failures of the screw conveyor or unsmooth discharge—this maintenance step is essential to ensure the normal operation of the production line related to the granular material silo.
- After filling the granular material silo with granular materials for the first time, the verticality of the silo and the tightness of bolts at various positions must be checked every day in the first 7 days. If they do not meet the requirements, adjustments and maintenance must be carried out. Later, the check is changed to once a week, and once every six months after half a year of use. Regular inspection of the granular material silo ensures its long-term stable operation and reduces the risk of equipment failure.
- In areas where the wind force often exceeds level 6, wind-resistant cables should be added to the granular material silo to enhance its wind resistance and ensure the safety of the granular material silo in harsh weather conditions.
- When filling the granular material silo with granular materials, it should not be overfilled, and the filling amount should not exceed 90% of its volume, that is, not exceed its upper material level height. This prevents material overflow and ensures the safe operation of the granular material silo.
- The dust collector of the granular material silo must not be turned on during the material filling process; after the filling is completed, the dust collector should be turned on in a timely manner and turned off after working for 5-10 minutes. Correct operation of the dust collector ensures the dust removal effect of the granular material silo and maintains a clean production environment.
- After opening the discharge door of the granular material silo, the handle of the discharge door should be locked to prevent the discharge door from closing automatically during the production process. This ensures the smooth discharge of materials from the granular material silo and avoids interruptions to the production line.
- When dust escapes from the dust collector of the granular material silo, the filter element of the dust collector should be cleaned in a timely manner. Use a special wrench (provided with the granular material silo) to remove the filter element, take it out from the top of the dust collector, and clean it with high-pressure gas or a soft brush. Damaged filter elements should be replaced in a timely manner, and the filter element should be inspected and cleaned at least once every six months. Regular maintenance of the dust collector ensures the dust removal efficiency of the granular material silo.
- Regularly inspect and clean the pressure relief valve on the top of the granular material silo and the powder around it to prevent granular materials from getting damp and caking, which may cause the pressure relief valve to fail. A comprehensive cleaning and inspection of the pressure relief valve should be carried out every six months to ensure the normal function of the granular material silo's safety components.
- The level indicator of the granular material silo should be disassembled every six months to clean the accumulated material on the rotating blade of the level indicator and the mounting base. This ensures the accurate measurement of the material level by the level indicator, providing reliable data support for the material management of the production line.
- Regularly inspect the air arch-breaking device of the granular material silo to ensure it is in a normal state. It is strictly forbidden to open the arch-breaking solenoid valve to allow compressed air to enter the granular material silo when the screw conveyor is not working. Correct use of the arch-breaking device prevents material arching in the granular material silo and ensures smooth material discharge.
- For the centralized dust collection system of the granular material silo, the residual material in the dust collection box should be cleaned in a timely manner to avoid affecting the dust removal effect. This maintains the overall dust removal performance of the granular material silo and meets the environmental protection requirements of the production site.
