Features
Pneumatic direct blaster eliminates a blockage by blasting the compressed air directly to the powder that caused adhesion or clogging. It has a large destruction force and is excellent in safety. It produces an effect especially on the powder that adheres when vibrated. Its operation is easy and multiple units can be operated simultaneously. The models are available in the tank capacity of 2.5L to 230L so that selection can be made depending on the size of tank and hopper, and the blockage situation. ※For the operating principle of air relay knocker, also refer to “Operating principle of flow aid”.
New valve mechanism improving maintenability
For the conventional blaster, once installed in the silo or hopper, it was necessary to replace the product itself when replacing a consumable part. This took lots of hard work because the product may have been installed to a high place. By adopting the new valve mechanism in which the above disadvantage is removed, a consumable part in the valve can be easily replaced at the installation site, which improves the maintenability.
All pressure tanks comply with design standards of class-2 pressure vessel
Like the production series (pneumatic direct blaster and pneumatic twin blaster), the pressure tank for pneumatic filling is designed and manufactured in accordance with the class-2 pressure vessel standards (JIS). Although the above standards are applied to pressure tanks with capacity of 40L or more, EXEN applies the standards to all models (20L to 230L) for customers to use them safely. In consideration of maintenance, the meter is mounted outside to be able to check whether pneumatic filling is sufficient in the pressure tank.
(standard equipment in all models)
Large effect of blockage elimination
Since it acts directly on the contents rather than vibrating or hitting from the outside of the container, the effect is large, so the dead stock remaining inside the silo is also less. In the case of the aggregate silo of the ready mixed concrete producer, it can be operated from the central control room, so it is adopted by many ready mixed concrete producer and is pleased.
Safety first in factory
Accidents have occurred continuously owing to reliance on man-powered work for eliminating blockage in silo. The blockage in silo is caused by an arching phenomenon and balance of contents. An imbalance from man-powered work causes the contents to start flowing, which will result in a large-scale accident. The pneumatic direct blaster is adopted in many sites for the purpose of preventing the above accident causing injury or death.
Variable injection force by pressure regulation
Adoption of mushroom valve method allows an injection force to be adjusted by changing the pressure of supplied air. If there is a request to make replacement for larger or smaller equipment, the issue can be solved by pressure regulation with unnecessary replacement work.
Nitrogen gas can also be used
If the contents are flammable or likely to be exploded, nitrogen gas can be used as injection air. The safety measures for explosion proof can be secured by the blaster, which results in cost reduction. This product has a large number of proven track records in the waste disposal plant, etc.
Dedicated nozzles are available as options
Various types of dedicated nozzles are available, which can be chose depending on the situation of adhesion or clogging and installation location.
For manufacturing of special nozzle with heat resistance of 1000℃ or more, contact EXEN.
