Therefore, under the conditions of narrow space and limited space, the air cannon cannot be installed, and the bin of the occasions is difficult to clean. However, in these places, the installation of an air cannon is often urgently needed to solve the problem of material blockage. The integrated air cannon system developed by the company excellently solves the problems of a storage bin and a pipeline with limited space and the application occasions needing intensive arrangement of the air cannons, and fills the blank in relevant aspects in China.

The conventional system and the working principle of the existing air cannon product are as follows:

the air cannon valve body and the air storage tank are integrated, and compressed air is directly filled into the air storage tank of each air cannon through a gas transmission pipeline or is filled into the tank through a quick discharge valve. When the air pressure in the air storage tank is the same as the air pressure in the air transmission pipeline, the balance is achieved, and the air cannon is in a waiting working state; when the control system sends a working instruction, a two-position two-way electromagnetic valve in the system acts to open a quick valve core in the quick discharge valve; because the quick valve core is opened, pressure difference is quickly formed on two surfaces of a closed piston in the air cannon, and the closed piston is opened; at the moment, a large amount of compressed air in the air storage tank is directionally sprayed out through the spraying pipe in a spraying explosion state, so that the effects of breaking an arch and clearing blockage are achieved.
