Specific embodiment

For content of the invention, feature and the effect of the present invention can be further appreciated that, hereby enumerate following examples, and coordinate accompanying drawing Describe in detail as follows, refer to Fig. 1.

As shown in Figure 1：Air bag punching type pneumatic mud relay pump includes the pump housing 1, air bag 2, enters mud pipe 3, A ball valve 4, mud extraction On pipe 5, B ball valve 6 and air bag 2 into and out of trachea 7 it is characterised in that：The pump housing 1 includes pump case 8, upper cover 9, low head 10, pump The upper end of shell 8 is welded with A ring flange 11, and upper cover 9 is welded with B ring flange 12, and A ring flange 11 and B ring flange 12 are tight with bolt Connect, when installing with maintenance air bag 2, ring flange can be dismantled, and sealing during operation is installed；Circumferentially equidistant in upper cover 9 It is welded and fixed eight suspension ring 13, the top of upper cover 9 carries inlet, outlet hole and single-way gas-discharge pipe 14, single-way gas-discharge pipe 14 can be with When open or close, to release the remaining gas being brought by enters mud pipe 3 in the pump housing 1, thus avoiding reducing effective operation volume；Lower envelope 10 integrally welded with pump case 8, and the center in low head 10 is welded with steel loop 15, and the both sides at center put in two into and out of mud Pipe 16；Air bag 2 is suspended in the pump housing 1, and the length of air bag 2 is less than the pump housing about 30cm, and its external diameter is identical with pump case 8 internal diameter, air bag 2 Top fixation into and out of trachea 7, into and out of trachea 7 upper cover 9 exposed into and out of pore by upper cover 9 top, and by outer Pipe be connected with air compressor machine carry out pressure-air fill with put replace exchange；The equidistant fixation of circumferencial direction along air bag 2 top Eight buckles 17, the connection corresponding with suspension ring 13 position of the position of buckle 17, air bag 2 is suspended in the pump housing 1, air bag 2 bottom Center fix a rope chain 18 and be connected with the steel loop 15 of center weldering in low head 10, when air bag 2 is put and exitted in inflation expansion The middle position of the pump housing 1 all can be in during contraction, air bag 2 upper end be fixed with ￠ 50mm into and out of trachea 7, it exposes upper cover 9 Outward；The material of described air bag 2 is nylon woven cloth mould glue；The length of described air bag 2 be less than the pump housing about 30cm, its external diameter with Pump case 8 internal diameter is identical.

During use, by air bag 2 being carried out filling, being exitted into and out of trachea 7, then air bag 2 volume with expanding and can reduce, When venting, so that air bag 2 is dwindled into a branch of, and A ball valve 4 is opened（Overbottom pressure by enters mud pipe 3 mud）, by enters mud pipe 3, A ball valve 4 to Mud is entered in the pump housing 1；When air bag 2 is inflated and expands, A ball valve 4 is closed, and B ball valve 6 is opened, due to air bag 2 expand then right In the pump housing 1, mud produces punching press, and mud pressure now is identical with inner gas pressure in air bag 2, thus complete adding to mud Press through journey, be enlarged the mud after pressure and discharge into and out of mud pipe 16 and by B ball valve 6 and sludge out pipe 5 through two.Due to air bag B Fill, deflation course, the mud in the pump housing 1 isolated by the outer wall of air bag 2, and mud is still in closed state, will not overflow, ring Guaranteed cost is good；Into and out of the volume of the mud flow rate in the pump housing 1 and air bag 2 and fill, frequency of exitting relevant, be easy to big flow operation, Reduces cost.Generally when using, form one group by three pump housings 1, i.e. an inflation, two other pump housing 1 in three pump housings 1 Venting, action is controlled by air distributor, work of sequentially rotating, thus it is guaranteed that three pump housings 1 form continuous adding Pressure, the enters mud pipe 3 on three pump housings 1 and sludge out pipe 5 are connected to a total enters mud pipe and a total mud extraction with pipeline respectively Pipe.

Its advantage is：Structure is simple, easy for installation, reduces labor intensity, due to air bag filling, deflation course, the pump housing Interior mud is isolated by the outer wall of air bag, and mud is still in closed state, will not overflow, therefore improve environmental-protecting performance, Reduce cost；In addition, during mud tube is defeated, pressurization in line pipe can be entered at any distance, be particularly suited for mountain area with The ecological dredging long-distance sand transport of the network of waterways.

Embodiment described above is only that the preferred embodiment of the present invention is described, the not model to the present invention Enclose and be defined, under the premise of the design spirit without departing from the present invention, the technical side to the present invention for the those of ordinary skill in the art Various modifications and improvement that case is made, all should implement in the protection domain of claims of the present invention determination.
