ATTACHED PULVERULENT AND GRANULAR MATERIAL SHAKE-DOWN APPARATUS

摘要

An attached pulverulent and granular material shake down apparatus which comprises a main body of a shock application device operable by a three-way valve and a high pressure air generation device connected to the shock application device main body. The shock application device main body is composed of a valve chamber formed with an air feed/discharge port connected to an air flow path and including an umbrella-type valve therein, a communication pipe communicating with a pressure accumulator chamber for storing or releasing a high pressure air in response to the operation of the umbrella-type valve, a piston which can be accelerated to a high speed by the high pressure air released, and a return spring. The apparatus is capable of providing variable shock application forces with the piston and selecting the required shock application forces according to the use conditions of the apparatus, namely the states of pulverulent and/or granular materials, kinds of the above materials, or structures or shapes of storage vessels used.
