Balance chamber supercharged piston fast reposition air cannon

Abstract

Balance chamber supercharged piston fast reposition air cannon comprises an air storage tank, an inlet pipe communicated with the air storage tank and a two-way valve used for controlling air entering in the air storage tank, a piston barrel, a piston, a piston barrel end plate and a piston type sealed exhaust control device consisting of a pumping chamber and an offsetting spring in the piston barrel are arranged on the air storage tank, the bottom surface of the piston is contacted with the nozzle of an outlet pipe in sealing way, and a countercurrent hole communicated with the pumping chamber and the air storage tank is arranged on the side wall of the piston. The invention is characterized in that a leak-off airway tube controlled by a two position two-way electromagnetic valve is arranged on the end plate of the piston barrel to communicate with the pumping chamber and the external environment, the piston is a cylindrical enclosed structure and a hole which is used for leak-off airway tube to pass is arranged on the bottom plate of the piston. The invention has the advantages that the pressure and the impact force putting on the piston and the offsetting spring can be largely reduced, the ring-snapping can be prevented, thus prolonging the service life of the equipments, and petty materials can be prevented from dropping in the air storage tank from the outlet pipe, thus ensuring the using effect of the equipment.

Description

Technical field: [0001] The present invention relates to equipment for clearing and breaking arches in various silos and powder transportation processes, in particular to a quick reset air cannon for a balance chamber pressurized piston. Background technique: [0002] The working principle of the air cannon is to store a certain volume of high-pressure gas in the tank. When in use, quickly open the piston valve and use the impact force generated by the instantaneous high-speed airflow to overcome the static friction and blockage of the material, and make the particles in the container or pipeline The material resumes its flow smoothly. The piston sealing system is the key equipment of the air cannon, which determines the performance of the air cannon. The company has designed a set of air cannon piston sealing system (a patent has been applied for in another case), and its structure is as follows figure 1 Shown: The gas storage tank is installed with a piston cylinder (5), a pis...

AI Technical Summary

Problems solved by technology

So in practice, the return spring is easily crushed

In the process of high-speed movement under a large force, the piston is also easily damaged, and the snap ring phenomenon occurs

On the other hand, when the outlet of the exhaust pipe is buried in the material, due to the static pressure, the material will enter the air cannon.
