Overview
Powder storage silos are used for sealed storage, transfer, and handling of powder materials. They effectively prevent dust dispersion and pollution, ensuring safe and moisture-proof storage of powder materials.The inner surface of the silo body is either mirror-polished or coated with PTFE (polytetrafluoroethylene). The smooth inner surface and large conical bottom design facilitate smooth discharge of powder and prevent metal ion contamination.It can be equipped with a mixing device or provided as a single silo body according to customer requirements.It is suitable for powder industries such as pharmaceutical, food, energy, plastic, mineral and metal powder, new energy, ceramics, and chemical engineering. Its diverse structural types meet various application needs.Specification & Capacity: A series of capacities including 100L, 200L, 300L, 400L, 500L, 600L, 800L, 1000L, 1500L, 1800L, 2000L, etc.Powder storage silos are mainly used for the transfer and storage of powder materials. In the silo design, various performance parameters and physical-chemical requirements are fully considered, such as the temperature control environment, dryness-humidity requirements, discharging, and cleanliness of the stored materials.The appropriate storage capacity is calculated based on the customer's on-site working conditions, material consumption, and other factors.
Advantage of Powder Storage Silo:
- Easy to clean and stable in structure.
- Wide application range, meeting the storage needs of all powder materials.
- Efficiently handle batch bulk materials in the automated production process.
- Quantitative and accurate delivery of various materials.
- Ladder design for easy inspection and maintenance.
- Accessories are developed and manufactured using advanced industry technologies, featuring durability and extremely low failure rate.
Application of Powder Storage Silo:
As an important equipment in chemical production, it is not only used for storing process powder materials (raw materials, products, intermediate products, etc.) and auxiliary materials (such as catalysts), but also for homogenizing material properties, balancing process materials, and emergency storage of materials in case of accidents.
Maintenance of Powder Storage Silo:
- Within the first 7 days after the installation of the powder storage silo, the foundation must be inspected daily for settlement. After filling the silo with powder, the foundation must be regularly inspected for settlement.
- Before filling the powder storage silo with powder for the first time, the residual debris inside the silo must be cleaned up to prevent it from mixing into the powder, which may cause screw conveyor failure or unsmooth discharging.
- After filling the silo with powder for the first time, the verticality of the silo and the tightness of bolts at all positions must be inspected daily for the first 7 days. If the requirements are not met, adjustments and maintenance must be carried out. Later, the inspection shall be conducted weekly, and once every six months after half a year of use.
- In areas where the wind force often exceeds level 6, wind-resistant cables should be installed for the powder storage silo!
- The powder storage silo should not be overfilled when filling with powder, and the filling amount should not exceed 90% of its volume, i.e., not exceed its upper level height.
- The dust collector must not be turned on during the material filling process. After the filling is completed, the dust collector should be turned on in time and turned off after 5-10 minutes of operation.
- After opening the discharge door of the powder storage silo, the handle of the discharge door must be locked to prevent the discharge door from closing automatically during production.
- When dust escapes from the dust collector of the powder storage silo, the filter element of the dust collector should be cleaned in time. Use a special wrench (provided with the 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 time, and the inspection and cleaning should be conducted at least once every six months.
- Regularly inspect and clean the pressure relief valve on the silo top and the powder around it to prevent the powder from getting damp and caking, which may cause the pressure relief valve to fail. Conduct a comprehensive cleaning and inspection of the pressure relief valve once every six months.
- The level indicator should be disassembled every six months to clean the accumulated material on the rotating blade of the level indicator and the mounting base.
- Regularly inspect the air arch-breaking device of the powder storage silo to ensure it is in normal condition. It is strictly forbidden to turn on the arch-breaking solenoid valve to let compressed air enter the silo when the screw conveyor is not working.
- For centralized dust collectors, the residual material in the dust collection box should be cleaned in time to avoid affecting the dust removal effect.
