Abstract

The utility model provides a pneumatic pumping plant. The pneumatic pumping plant can solve problems that a submersible pump is unsuitable for pumping water in a shallow water area, the manual cleaning efficiency is low and time and labor are wasted in the prior art. The pneumatic pumping plant comprises a compressed air pipeline and a pumping pipeline. The pumping pipeline is provided with a compressed air pipeline inlet and an air and water mixture outlet, a water inlet pipeline is arranged on a body of the pumping pipeline in a communicated manner, an air and water mixture outlet portion of the pumping pipeline is a reduced opening with the inner diameter smaller than that of the pumping pipeline, and the compressed air pipeline extends into the pumping pipeline to such a degree that an exhaust port of the compressed air pipeline is positioned at the reduced opening of the pumping pipeline. The pneumatic pumping plant has the advantages that the pneumatic pumping plant is simple in structure and low in manufacturing cost, shallow accumulated water can be effectively pumped by the pneumatic pumping plant, and the work efficiency is greatly improved.

Description

Pneumatic water plug

Technical field

The utility model relates to pneumatic water plug, is particularly useful for the water yield few, the detaching of the inapplicable shallow water area water of submersible pump.

Background technique

Shipping industry is an industry that construction period is very long, many times, and such as all causing part area ponding on boats and ships in the situations such as sleety weather, tightness test.Generally with submersible pump, ponding is detached during the depth of water, adopt submersible pump can't be extracted into water when water is shallow, very easily cause the overload of pump, cause pump to damage, take a lot of work and adopt the labor cleaning to waste time and energy, especially winter, operating environment is abominable, be not suitable for the labor cleaning, and clear up untimely being easy to and freeze, more increased the cleaning difficulty.

Summary of the invention

The utility model provides a kind of pneumatic water plug, and the shallow water area that can solve the prior art existence should not use submersible pump to draw water, and labor cleaning's efficient is low, the problem that wastes time and energy.

For reaching above-mentioned technical purpose, the utility model is achieved by the following technical solutions: a kind of pneumatic water plug, comprise compressed air line and have the compressed air line entrance and the pumping conduit of air-water mixture outlet, be communicated with intake pipe on the body of described pumping conduit, the air-water mixture export department of described pumping conduit be internal diameter less than the reducing of described pumping conduit internal diameter, described compressed air line stretches in described pumping conduit to its relief opening and is positioned at pumping conduit reducing place.

Angle between described intake pipe and described pumping conduit is 20 °～90 °.

Described intake pipe is communicated in 1/3～3/4 position of described pumping conduit length direction.

Compared with prior art, the utility model water plug is simple in structure, and is cheap, can effectively detach the more shallow ponding of the depth of water, greatly improves operating efficiency.

Description of drawings

Fig. 1 is the structural representation of the pneumatic water plug of the utility model embodiment.

Embodiment

For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

With reference to shown in Figure 1, the pneumatic water plug of the present embodiment, comprise compressed air line 1 and have compressed air line entrance 2-1 and the pumping conduit 2 of air-water mixture outlet 2-2, be communicated with intake pipe 3 on the body of pumping conduit 2, the air-water mixture export department of pumping conduit 2 be internal diameter less than the reducing 2-3 of pumping conduit 2 internal diameters, compressed air line 1 stretches in pumping conduit 2 until its relief opening is positioned at pumping conduit reducing 2-3 place.

during work, the pneumatic water plug of the present embodiment is placed in the boats and ships shoal waters, when not passing into pressurized air, water level in intake pipe 3 and extraneous shoal water water level maintain an equal level, after passing into pressurized air, swiftly flowing pressurized air is discharged (in figure, arrow A is that pressurized air flows to) from the relief opening 1-1 that compresses air conduit 1, the sealing that is subject to reducing 2-3 stops makes the interior formation negative pressure of pumping conduit 2, thereby generation suction, water in intake pipe 3 is drunk up, export 2-2 by air-water mixture and discharge (in figure, arrow B is water (flow) direction), be particularly useful for drawing water of shallow water area.The minimum diameter of reducing 2-3 front end is 1/3～1/2 of pumping conduit 2 internal diameters.

Angle α between described intake pipe 3 and described pumping conduit 2 is advisable with 20 °～90 °, and in the present embodiment, α is 50 °, discharges so that the current in intake pipe 3 enter pumping conduit 2 swimmingly.

Intake pipe 3 is communicated in 1/3～3/4 position of pumping conduit 2 length directions, can change flexibly according to concrete shallow-water environment.

The above, it is only preferred embodiment of the present utility model, be not to be the utility model to be done the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
