Description

Diaphragm pneumatic squeezer

Technical field:

The utility model relates to a kind of air pressure squeezer, particularly a kind of diaphragm pneumatic squeezer.

Technical background:

Air pressure squeezer, claims again pulsometer pump, is positive displacement structure, and principle is directly to utilize atmospheric pressure that the water in volume space is realized to lift.Air pressure squeezer is provided with suction valve, outlet valve, water inlet safety check, waste pipe with safety check, and its suction valve and outlet valve, be sometimes arranged to integrative-structure, as air inlet and exhaust valve or distributing valve.For single-cylinder type air pressure squeezer, in the time being full of water in air pressure squeezer volume space, air inlet system is opened, and compressed gas enters, and hydraulic pressure is hoisted.After water has been pressed, air inlet system cuts out simultaneously venting gas appliance and opens, and pressurized air is discharged to the external world, then under ambient pressure, and automatic feeding water, water continues setting-out completely afterwards to eminence.The bitubular or multi-cartridge air pressure squeezer are that two or more monotubular air pressure squeezer waste pipes are connected in parallel, and make the valve of intake and exhaust coordinate operation, to alleviate setting-out to the pulse phenomenon in eminence process.

The advantage of air pressure squeezer is can utilize only to have the source of the gas of slight pressure to drive, the pressure difference that gas has also can maximum the lift that is converted to water, and the use of also can connecting easily of air pressure squeezer, can utilize low-pressure gas source to realize high-lift pumping up water as power.But, air pressure squeezer is in work, be in contact with one another with the surface of liquid that is implemented lift as having of the power body of calming the anger, therefore use in some cases this kind of air pressure squeezer, when volatile material is realized to lift, partially liq can volatilize to the external world, or utilizes uncleanly while having the body of calming the anger to realize lift to clean material, and this material can be polluted.

Model utility content:

The utility model has overcome the deficiency of traditional air pressure squeezer, in the time using compressed gas to drive air pressure squeezer to pump up water eminence, can effectively avoid cross pollution possible between gas and water body.Specifically be achieved by the following technical solution:

Described diaphragm pneumatic squeezer, its surrounding of the barrier film of setting is fixed on air pressure squeezer inside, air pressure squeezer inner volume is at least cut apart and be divided into two spaces, and one of them is intake and exhaust space for the space of cutting apart, and one for entering drainage space.

Described diaphragm pneumatic squeezer, is characterized in that intake and exhaust space UNICOM's air inlet that it is inner and the valve of exhaust, enters pipeline or the valve of the water inlet of drainage space UNICOM and draining.

The air pressure squeezer of said structure, its running is:

In the time of INO, the body of calming the anger enters intake and exhaust space, and barrier film is under pressure, and intermediate portion, to entering the flexible displacement of drainage space, squeezes into drainage space, hydraulic pressure can be hoisted; In the time that suction valve cuts out, outlet valve is opened, and the body of calming the anger in intake and exhaust space, discharged to the external world, enters drainage space water inlet, and barrier film intermediate portion is pressed towards intake and exhaust space, and intake and exhaust space is extruded into minimum.The barrier film arranging is isolated two volume spaces mutually, also realizes isolation thereby make to be present in respectively between the compressed gas of two volume spaces and water body, in the interactive conduction of pressure, has also avoided cross pollution.

Diaphragm pneumatic squeezer as above, the barrier film of its setting, requires in the situation that surrounding is fixing, and intermediate portion should be able to carry out flexibility or the elastic movement that amplitude is larger under pressure.Generally barrier film can be arranged to pocket type structure, and the opening of pocket type barrier film is fixed on to air pressure squeezer inside, in this case, the drainage procedure that enters of air pressure squeezer is also the process of the flexible displacement of membrane bag simultaneously, its advantage is that diaphragm pneumatic squeezer is avoided as far as possible pressure loss in the time of work, also can extend the working life of barrier film simultaneously.

Constantly entering in drainage procedure, also constantly there is flexibility or elastic movement in set barrier film, or based on other reasons, breakage may appear in barrier film, cause the medium in two spaces mutually leak and occur polluting, therefore the induction installation that leaks hunting for barrier film generally should be set.

Air pressure squeezer arranges double-deck barrier film, is a kind of method of leaking hunting, once also can prevent that barrier film from occurring that damaged horse back occurs medium leakage and causes polluting simultaneously.Space in the middle of double-deck barrier film, its inner fluid that is different from liquids and gases composition and there is no contaminativity of placing, this segment fluid flow can the rotten warning device of UNICOM.In the time finding that this part fluid composition changes, can judge that breakage has appearred in one of them barrier film, should change in time or repair.According to the feature of its motion mode of barrier film arranging, also second layer barrier film can be arranged on to the easily place of breakage of first layer barrier film.

The operation of the intake and exhaust valve that a kind of air pressure squeezer uses is to cause braking by buoyancy aid or liquid level sensor, and the air pressure squeezer that barrier film is set can be placed a certain amount of liquid as the intake and exhaust valve that uses this structure in intake and exhaust space.When enter drainage space water inlet under ambient pressure time, or under atmospheric pressure, enter drainage space and pump up water in eminence, liquid level in intake and exhaust space can change along with the flexible displacement of barrier film, and then can, by controlling buoyancy aid or liquid level sensor, air inlet and exhaust valve be realized under suitable state and open and close switching.

The mode that another startup of the variation according to liquid level intake and exhaust valve of air pressure squeezer of barrier film is set is directly to make the compliant motion part of barrier film connect sensing or transmission device, and then opens the switching keying of robbing intake and exhaust valve.

As required, the air pressure squeezer of barrier film is set, its barrier film can be arranged in an independent container.Arrange barrier film container a side by pipeline with the container UNICOM of intake and exhaust valve is set.

Intake and exhaust valve for air pressure squeezer does not does not open and close situation about switching according to the variation of liquid level, such as keying is switched in timing, the barrier film of air pressure squeezer arranges the interference of the motion that generally needn't consider barrier film to air inlet and exhaust valve running, under the emptying as far as possible requirement of the gas that can make intake and exhaust space, intake and exhaust space with enter drainage space and separate.

In order to make diaphragm pneumatic squeezer have higher efficiency, the fluid that enters drainage space should not have larger compressibility, and therefore general every nook and cranny all should be full of water and not retain air.

Sometimes, compressed gas contains part moisture, easily in the intake and exhaust space of air pressure squeezer, be detained, or in compressed gas evacuation procedure, may take part out of and be placed on the moisture in intake and exhaust space, therefore, water regulating valve should be set, make water level in intake and exhaust space can meet the job requirement of liquid level sensor or buoyancy aid.The keying of described water regulating valve also can regulate by the motion amplitude of barrier film.The water regulating valve arranging also can be directly respectively UNICOM enter drainage space and intake and exhaust space, in the time of the moisturizing of intake and exhaust space requirement, directly utilize into the water of drainage space and supplement.

The air pressure squeezer that barrier film is set as above, also can be connected in parallel, and composition bitubular barrier film air pressure squeezer, to alleviate the pulse problem in the process of pumping up water, realizes the stable eminence of pumping up water.

Apparatus structure described in the utility model is simple, is convenient to install endurance, long service life.
