Description

Desilting dredge pump

Technical field

The utility model relates to a kind of desilting dredge pump.

Background technique

Desilting blowdown at present and conveying contain bulk, granular liquid mixture, usually use the centrifugal pump of sewage pump, submerged pump and so on, in the working procedure since the impact force of transfer block can to add megaseisms moving, fixedly the support body of centrifugal pump is limited to by easily in the place, operation easier is bigger, and the time that maintenance spends in the centrifugal pump using process of prior art is more, and user cost is higher.

The model utility content

Technical problem to be solved in the utility model is: a kind of desilting dredge pump is provided, and this kind desilting dredge pump is easy to operate, reduces maintenance load, can enlarge using scope, reduces user cost.

Solve this technical problem, the technical solution of the utility model is: a kind of desilting dredge pump, it comprises housing, mixing tube, discharge tube, supply pipe, horn mouth, flange and base, the bottom of described mixing tube and the top of housing are connected as a single entity, the top of mixing tube and the bottom of discharge tube are connected as a single entity, described base is positioned at lower part of frame, described supply pipe, horn mouth and flange are the structure that fuses, described supply pipe is positioned at bell-mouthed top, described horn mouth is connected with base, described flange is positioned at the top of base, described housing and supply pipe, horn mouth, form high pressure fluid chamber between the flange, has the slit between the top of described supply pipe and the mixing tube, described housing middle part has a high-pressure liquid that feeds high pressure fluid chamber and enters the hole, described flange has the inclined hole in the feeding supply pipe uniform more than six, and each inclined hole on the described flange all communicates with high pressure fluid chamber.

Described horn mouth is connected with base through screws.

Described base is provided with the grid that is positioned at the horn mouth below.

Inclined hole quantity on the described flange is eight.

The utility model desilting dredge pump adopts such structure, has reduced the site factors restriction, and is easy to operate, can reduce maintenance load, enlarges using scope, reduces user cost.

Description of drawings

Below in conjunction with accompanying drawing the utility model desilting dredge pump is done explanation in further detail;

Fig. 1 is the structural representation of the utility model desilting dredge pump;

Fig. 2 is the elevational schematic view of base shown in Figure 1;

In Fig. 1, Fig. 2,1, base; 2, horn mouth; 3, flange; 4, high-pressure liquid enters the hole; 5, housing; 6, supply pipe; 7, mixing tube; 8, discharge tube; 9, high pressure fluid chamber; 10, screw; 11, grid.

Embodiment

As Fig. 1, shown in Figure 2, desilting dredge pump comprises housing 5, mixing tube 7, discharge tube 8, supply pipe 6, horn mouth 2, flange 3 and base 1, the top of the bottom of mixing tube 7 and housing 5 is connected as a single entity, the bottom of the top of mixing tube 7 and discharge tube 8 is connected as a single entity, base 1 is positioned at the bottom of housing 5, supply pipe 6, horn mouth 2 and the structure of flange 3 for fusing, supply pipe 6 is positioned at the top of horn mouth 2, horn mouth 2 is connected with base 1, flange 3 is positioned at the top of base 1, housing 5 and supply pipe 6, horn mouth 2, form high pressure fluid chamber 9 between the flange 3, has the slit between the top of supply pipe 6 and the mixing tube 7, housing 5 middle parts have a high-pressure liquid that feeds high pressure fluid chamber 9 and enter hole 4, flange 3 has the inclined hole in eight uniform feeding supply pipes 6, each inclined hole on the flange 3 all communicates with high pressure fluid chamber 9, and horn mouth 2 is connected by screw 10 with base 3.The grid 11 that is positioned at horn mouth 2 belows is installed on the base 1, can effectively stops the transfer block of especially big volume, for can normal operation in deep water, several sipes have been opened in the base bottom, and when base during near mud, water can constantly replenish into.

During use, high pressure water or pressurized air are advanced the high pressure fluid chamber 9 that hole 4 feeds housing 5 through high-pressure liquid, high pressure water can use water pump to produce, pressurized air can be produced by compressor, high pressure water or pressurized air are rushed in the mixing tube 7 by the slit, flow to discharge tube 8 directions, form low pressure area, the liquid of solid particle or thick wet feed are contained under the barometric pressure effect, by the grid on the base 11 in the external world, horn mouth 2, supply pipe 6 enters mixing tube 7, in mixing tube, high pressure water or pressurized air are passed to the fluid of being pumped to part energy, and its energy is increased, and enter discharge tube again.Inclined hole on the flange can increase flow, and the sludge blanket that hardens is had good souring, guarantees the work continuity.

The utility model desilting dredge pump adopts such structure, compared with prior art, has the following advantages:

1, enlarged using scope, but both pumping bulks, granular dry material, but also pumping contains the liquid of solid particle, and does not have seal arrangement, and at the higher material of delivery temperature, carry aspect the poisonous and hazardous material, with the obvious advantage.

2, in the using process, can produce gas bag material effect, can effectively prevent the wearing and tearing between transfer block and the tube wall, improve the working life of pump, reduce maintenance load.

3, simple in structure, easy to operate, realize telecontrol easily, reduced the site factors restriction.

4, can operation in deep water.
