Embodiment
With reference to specific accompanying drawing, the invention will be further described.
As shown in figs 1 to 6：The pneumatic positive displacement sewage pump of density transform includes pump case 1, shell 1.1, the upper limit
Position block 1.3, lower position block 1.4, upper lid 1.5, move back and forth son 2, non-return piece 2.1, ladle bowl 2.2, yielding rubber post 2.3, sealing
Brush 2.4, mozzle 2.5, bottomed support 2.6, air-channel system 3, air inlet helix tube 3.1, air inlet switch valve 3.2, waterproof and breathable
Ring 3.3, outlet helix tube 3.4, outlet pipe 4 etc..
As shown in Figure 1 and Figure 2, the present invention includes pump case 1, and the pump case 1 includes shell 1.1, on the bottom plate in shell 1.1
Be vertically arranged double-rod, be arranged in double-rod can pump move back and forth son 2, the bottom sides hollow out of shell 1.1 is convenient
Liquid is from bottom by the way that the inside upper part of shell 1.1 is provided with upper limit position block 1.3, and lower inside is provided with lower position block 1.4, shell 1.1
The upper lid 1.5 of top flange connection, upper lid 1.5 connects with outlet pipe 4, and outlet pipe 4 is interior to be provided with non-return piece；It is as shown in figure 3, described
Moving back and forth son 2 includes ladle bowl 2.2, mozzle 2.5 is provided with the inner chamber of ladle bowl 2.2, the top of mozzle 2.5 is provided with non-return piece
2.1, the top of ladle bowl 2.2 is provided with yielding rubber post 2.3, and the outside of ladle bowl 2.2 is provided with sealing brush 2.4, and the bottom of ladle bowl 2.2 is set
There is bottomed support 2.6；The son 2 that moves back and forth is connected by air inlet pipe and escape pipe with air-channel system 3, as Figure 4-Figure 6,
The air-channel system 3 includes air inlet helix tube 3.1, outlet helix tube 3.4 and is arranged between ladle bowl 2.2 and mozzle 2.5
Waterproof and breathable ring 3.3, one end of the air inlet helix tube 3.1 passes through air inlet switch valve 3.2 and moves back and forth the air inlet of son 2
Pipe connects, and the other end connection external feed stream of pump case 1 of air inlet helix tube 3.1, one end of outlet helix tube 3.4 is with moving back and forth son
2 escape pipe connection, the other end connection outside outlet of pump case 1 of outlet helix tube 3.4；The upper limit position block 1.3 can trigger into
Air cock valve 3.2 is closed, and lower position block 1.4 can trigger air inlet switch valve 3.2 and open.
The operation principle and the course of work of the present invention：The pneumatic positive displacement sewage pump of density transform is arranged on sewage
Bottom of pond, the original state of sewage pump is to move back and forth son 2 in the bottom of pump case 1, as shown in fig. 7, being touched by lower position block 1.4
Hair air inlet switch valve 3.2 is opened, and gas enters in the cavity for moving back and forth son 2, and liquid is slowly discharged, and it is whole to move back and forth son
Volume density reduces, and moves back and forth son 2 and overcomes resistance to move upwards, promotes the liquid above non-return piece up to move；Reach pump case 1
During top, closed as shown in figure 8, upper limit position block 1.3 triggers air inlet switch valve 3.2, now move back and forth gas in sub 2 cavitys
Gradually discharge, liquid progress into, and move back and forth sub 2 global densities increase, when density gradually increases, start to sink, back and forth
The liquid of the mobile lower section of son 2 passes through from the pod apertures 2.5 for moving back and forth son 2, into the top of non-return piece；When arrival pump case 1
Bottom, upper limit position block 1.4 trigger air inlet switch valve 3.2 and opened again, and gas enters in the cavity for moving back and forth son 2, back and forth
2 density of mobile son gradually reduce, and buoyancy increase, drive liquid to move up, and and so on, substantial amounts of liquid enters outlet pipe 4,
The non-return piece set in outlet pipe 4 prevents liquid from flowing back.
Ventilation Rate determines the reciprocating rate of sewage pump, also determines water flow.When sewage quantity is less than pump case 1 in pond
During height, due to being pneumatic, sewage pump will not be burnt out because of overheat；Sewage pump is heavy caliber using survey, low flow velocity,
So being not easy inspiration large volume solid blocks the pump housing.
