Submerged diaphragm type air cannon

Abstract

The invention relates to a submerged diaphragm type air cannon which comprises an air storage tank, an air inlet pipe, a vent pipe and a connection flange which are arranged on the air storage tank. The submerged diaphragm type air cannon is characterized in that a submerged diaphragm valve is installed at the connection flange of the air storage tank; the vent pipe penetrates through a tank body and is connected with the diaphragm valve directly; and an elastic diaphragm is used for sealing an air inlet pipe nozzle of the vent pipe and controlling the vent pipe to exhaust. The working theory of the submerged diaphragm type air cannon is as follows: air enters into the air storage tank through the air inlet pipe; when the pressure in the tank reaches a set value, and the tank is required to be exhausted to impact material, the diaphragm valve is opened, and high-temperature air enters into the vent pipe through an annular air duct of a submerged pulse valve instantly and is ejected out through a vent pipe port to form a high-speed jet flow which impacts a material jammed position, so as to achieve the goals of dredging and cleaning. After the process is finished, the submerged diaphragm valve closes automatically. The air cannon has the advantages of enjoying simple structure, convenient installation, being capable of being repaired on line, causing no influence on production, being capable of realizing automatic control and continuous work and having long service life.

Description

technical field [0001] The invention relates to a blockage remover for preventing materials from arching and agglomeration and wall hanging in powder conveying pipelines and large and medium-sized containers, in particular to a submerged diaphragm air cannon. Background technique [0002] The air cannon is a special device to prevent and remove the phenomenon of material arching, sticking and blocking of the silo and other large and medium-sized containers such as various types of silos, hoppers, etc. Its working principle is to suddenly open the exhaust pipe of the gas storage tank, and rely on the pressure difference between the high-pressure gas in the gas storage tank and the ambient air pressure to generate a high-speed jet, which directly rushes into the blocked and stagnant area of ​​the material. When in contact with the material, the speed can be converted into pressure energy immediately, overcoming the arching or sticking of the warehouse due to static friction, s...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to overcome the defects that the general exhaust pipe control valve is easy to get stuck, wears quickly, has a short life, and produces eddy currents under high-speed airflow, has large flow resistance and is not easy to repair online. And proposed a new type - submerged diaphragm air cannon, the air cannon structure is simple, easy to install and maintain, strong impact
