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
The present invention relates to prevent in powder conveying pipe and the large and medium-sized container Cleaning device for pipeline of material arch camber and caking and wall wall built-up, be specifically related to submerged diaphragm type air cannon.
Background technology
Air bubble is to prevent and remove in the big-and-middle-sized container such as all types of feed bins, hopper the material arch camber of locating with tube furcation place and drop shaft, slide slope etc., the isolated plant of phenomenons such as sticking storehouse obturation.Its principle of work is the freeing pipe that throws open storage tank, rely on interior high pressure gas of storage tank and the difference of pressure between the ambient pressure, produce the jet of ejection at a high speed, directly pour the obstruction retention areas of material, when jet contacted with material, speed can change into the pressure energy immediately, overcame the arch camber or the sticking storehouse that form because of static friction force, make in the storehouse material recover flow by gravity or make pipeline continue to play the effect that transports material, guarantee the continuity of Flow of Goods and Materials.
The critical component of air bubble is the by-pass valve control of freeing pipe, and the performance characteristics of the by-pass valve control of freeing pipe has determined performance, life-span of air bubble etc.The freeing pipe by-pass valve control of air bubble use both at home and abroad generally has piston valve, right angle film plate valve, 2/2-way valve etc. multiple at present.The piston cylinder operator complexity, easily stuck, need electromagnetic valve that it is controlled simultaneously, and electromagnetic valve is prone to fault, especially when air bubble et out of order situation, can not carry out online reparation, cause and produce inconvenience; The right angle film plate valve easily produces eddy current under high velocity air, resistance to flow is big, reduces the performance of air bubble.2/2-way opening of valves speed is slow, and it is not quick detachable to break down, and repairs.
Summary of the invention
Purpose of the present invention is just at existing problem in the above-mentioned prior art, overcome that general freeing pipe by-pass valve control is easily stuck, quick abrasion, the life-span is short and produce eddy current under high velocity air, resistance to flow is big and be difficult for the defective of online reparation, and proposition is a kind of novel---submerged diaphragm type air cannon, this air bubble is simple in structure, and installation and maintenance make things convenient for impulsive force big.
The objective of the invention is to be achieved through the following technical solutions: air bubble of the present invention comprises storage tank, be arranged on air inlet pipe, freeing pipe and butt flange on the storage tank, butt flange overlaps with axis, freeing pipe air extractor duct position, wherein: the submerged diaphragm valve is installed on the storage tank butt flange, freeing pipe pass tank body directly and the submerged diaphragm valve link together, by the elastic memberance in the submerged diaphragm valve freeing pipe air inlet mouth of pipe is sealed and controls the freeing pipe exhaust.
In the present invention, the submerged diaphragm valve comprises valve seat, be arranged on the support and connection pipe in the valve seat, elastic memberance is fitted on the valve seat by valve gap, is provided with spring between diaphragm and the valve gap, the valve gap end face is provided with the elasticity Small diaphragm-piece and is compressed by loam cake, inner chamber is divided into epicoele, lumen and cavity of resorption, in, be provided with between the cavity of resorption and connect the duct, lumen is provided with deflation hole, isolate by the elasticity Small diaphragm-piece between lumen and the epicoele, isolate by elastic memberance between cavity of resorption and the gas storage tank body.
The mouth of pipe of freeing pipe air inlet when mounted directly is inserted in the support and connection pipe of submerged diaphragm valve, is provided with seal ring between the two.
The present invention includes two kinds of versions, a kind of is the corresponding position, two side that submerged diaphragm valve and freeing pipe air extractor duct position are separately positioned on the gas storage tank body, and another kind is the corresponding position, both ends that submerged diaphragm valve and freeing pipe air extractor duct position are separately positioned on the gas storage tank body.
Storage tank air inlet pipe of the present invention is provided with air intake valve, with the inflation of control to tank body.
Principle of work of the present invention is: open the by-pass valve control on the air inlet pipe, gas enters storage tank, after the pressure in the storage tank reaches setting value, when needing exhaust to impact material, open the submerged diaphragm valve, the instantaneous ring-shaped ventilation road through the submerged pulse valve of high pressure gas enters freeing pipe, come out from the freeing pipe port injection, form high-speed jet, impact material obstruction place, reach mediation and cleaning purpose.After process was finished, the submerged diaphragm valve cut out, and entered next circulation.
When faults such as valve appearance damage, because the submerged diaphragm valve is installed in the storage tank outside, the air inlet port of freeing pipe is sealed by the elastic memberance in the valve, get final product by simple this valve interface that directly inserts of freeing pipe during installation, can be under the situation that does not influence production, the valve of air bubble is carried out part exchanging.
Remarkable advantage of the present invention is: simple in structure, easy for installation, can onlinely repair, and do not influence production, and can realize automatic guidance, continuous working, long service life.
