Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in figs 1 to 6: described density transform pneumatic positive displacement sewage pump includes pump case 1, shell 1.1, double-rod 1.2, upper limit position block 1.3, lower position block 1.4, upper cover 1.5, moves back and forth son 2, non-return sheet 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 serpentine pipe 3.1, air inlet switch valve 3.2, waterproof and breathable ring 3.3, give vent to anger serpentine pipe 3.4, outlet pipe 4 etc..
As shown in Figure 1 and Figure 2, this utility model includes that pump case 1, described pump case 1 include shell 1.1, the base plate in shell 1.1 is vertically arranged double-rod 1.2, in double-rod 1.2 sheathed pump move back and forth son 2, the bottom sides hollow out of shell 1.1, facilitates liquid to pass through from bottom, and shell 1.1 inside upper part is provided with upper limit position block 1.3, lower inside is provided with lower position block 1.4, the top flange of shell 1.1 connects upper cover 1.5, and upper cover 1.5 connects with outlet pipe 4, is provided with non-return sheet in outlet pipe 4；As shown in Figure 3, the described son 2 that moves back and forth includes ladle bowl 2.2, the inner chamber of ladle bowl 2.2 is provided with mozzle 2.5, the top of mozzle 2.5 is provided with non-return sheet 2.1, the top of ladle bowl 2.2 is provided with yielding rubber post 2.3, the outside of ladle bowl 2.2 is provided with sealing brush 2.4, and the bottom of ladle bowl 2.2 is provided with bottomed support 2.6；The described son 2 that moves back and forth is connected with air-channel system 3 with escape pipe by air inlet pipe, as Figure 4-Figure 6, described air-channel system 3 includes air inlet serpentine pipe 3.1, give vent to anger serpentine pipe 3.4 and the waterproof and breathable ring 3.3 that is arranged between ladle bowl 2.2 and mozzle 2.5, one end of described air inlet serpentine pipe 3.1 is connected with the air inlet pipe moving back and forth son 2 by air inlet switch valve 3.2, the other end of air inlet serpentine pipe 3.1 connects pump case 1 external feed stream, give vent to anger serpentine pipe 3.4 one end with move back and forth son 2 escape pipe connect, the other end of serpentine pipe 3.4 of giving vent to anger connects that pump case 1 is outside gives vent to anger；Described upper limit position block 1.3 can trigger air inlet switch valve 3.2 and close, and lower position block 1.4 can trigger air inlet switch valve 3.2 and open.
Operation principle of the present utility model and work process: described density transform pneumatic positive displacement sewage pump is arranged at the bottom of cesspool, the original state of sewage pump is to move back and forth son 2 in the bottom of pump case 1, as shown in Figure 7, triggered air inlet switch valve 3.2 by lower position block 1.4 to open, gas enters in the cavity moving back and forth son 2, and liquid is slowly discharged, and moves back and forth sub-global density and reduces, moving back and forth son 2 overcomes resistance to move upward, and promotes the liquid above non-return sheet up to move；When reaching pump case 1 top, as shown in Figure 8, upper limit position block 1.3 triggers air inlet switch valve 3.2 and closes, in now moving back and forth sub 2 cavitys, gas is gradually discharged, and liquid progresses into, and moving back and forth sub 2 global densities increases, when density is gradually increased, start to sink, move back and forth the liquid below son 2 and pass from the pod apertures 2.5 moving back and forth son 2, enter the top of non-return sheet；When the bottom arriving pump case 1, upper limit position block 1.4 again triggers air inlet switch valve 3.2 and opens, gas enters in the cavity moving back and forth son 2, move back and forth sub 2 density to be gradually lowered, buoyancy increases, and drives liquid to move up, and so forth, substantial amounts of liquid enters outlet pipe 4, and the non-return sheet arranged in outlet pipe 4 prevents liquid from refluxing.
Ventilation Rate determines the reciprocating rate of sewage pump, also determines discharge.When in pond, sewage quantity is less than pump case 1 height, owing to being pneumatic, sewage pump will not burn out because of overheated；Sewage pump uses survey to be heavy caliber, low flow velocity, so being not easy the inspiration large volume solid blocking pump housing.
