Description

Strength lifting device

Technical field

The utility model relates to a kind of fluid transport machinery, is specifically related to a kind of strength lifting device.

Background technique

Metallurgy, mine, industry such as coloured all produce a large amount of muddy waters, contain the impurity of significant proportion in the water.This water wear and tear in cyclic process water pump and pipeline reduce water pump and pipeline working life; What is more, behind the contamination precipitation, will stop up pump entrance, influences the trouble-free operation of pipe network.Strength lifting device can be provided with before pond pump, the impurity that precipitates is withdrawn, or directly replace water pump.The Pneumatic lift of Chu Xianing all had following deficiency in recent years: the head suction port is one, the air outlet that is about to compressed air hose is set directly in the head, because this set, make stock column rising route undulate in the course of the work, to head, riser wearing and tearing acutely, complete machine is reduced working life greatly; And circulating pipe passes from head inside, takies the head inner space, and working efficiency reduces; Head, the every performance of riser material are lower, influence complete machine working life.

The model utility content

The purpose of this utility model is to overcome the prior art deficiency, provides a kind of and can improve stock column stability, simple, efficient, strength lifting device that the life-span is long.

To achieve these goals, strength lifting device of the present utility model, comprise guiding gutter with top cover and seal bowl, riser, head, compressed air hose, described head is arranged on the foot of described strength lifting device, link to each other with the bottom of riser and the air outlet of compressed air hose, the top of described riser extends into the guiding gutter that is arranged on described strength lifting device the topmost part, described guiding gutter is provided with discharge port, described head inside is provided with dividing plate, described dividing plate is divided into upper space and lower space with described head inside, the bottom of described riser is passed described dividing plate and is extended to described lower space, the air outlet of described compressed air hose is positioned at described upper space, is evenly equipped with a plurality of pores on the described dividing plate.

Also be provided with circulating pipe, described circulating pipe is arranged on the described head outside, and the water outlet of described circulating pipe and the suction inlet of described head are set up in parallel.

Described pore is evenly to distribute on the circumference in the center of circle at the longitudinal shaft with described head.

The quantity of described pore is 3.

The internal surface of described head is provided with the wear-resistant ceramic layer.

Described head and described riser are made by rare-earth alloy material.

The top of described head is cylindrical body, and the bottom is a taper, and described dividing plate is arranged on the cylindrical body.

Advantage of the present utility model is:

1. owing in head, be provided with the dividing plate that has a plurality of inlet holes that are uniformly distributed along the circumference, make head inside be divided into upper space and lower space, thereby increased the quantity of head suction port in fact, and because pore is evenly arranged, and then improved stock column stability, and alleviated head, riser wearing and tearing, increased the working life of complete machine.

2. circulating pipe stretches out from the head outside, increases the head inner space, has improved working efficiency.

3. head, riser adopt the rare earth alloy material, and are provided with the wear-resistant ceramic layer at the head internal surface, thereby significantly improve machine life.

Description of drawings

Fig. 1 is strength lifting device one an embodiment's of the present utility model structural representation;

Fig. 2 is along the sectional view of A-A among Fig. 1.

Embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described.

With reference to Fig. 1-2, an embodiment of strength lifting device of the present utility model, it comprises: guiding gutter 4, riser 3, head 1, compressed air hose 2 with top cover and seal bowl 5.Head 1 is positioned at the foot of whole strength lifting device, links to each other with compressed air hose 2 with riser 3, and the topmost part of strength lifting device is a guiding gutter 4, and top cover and seal bowl 5 are housed on the guiding gutter 4, has discharge port 7 on the sidewall of guiding gutter 4.The top of described head 1 is cylindrical body, and the bottom is a taper, and dividing plate 8 is arranged on this cylindrical body, so that good transducing space to be provided.Dividing plate 8 is divided into upper space and lower space with head inside, the bottom of riser 3 is passed dividing plate 8 and is extended to this lower space, the air outlet of compressed air hose 2 is positioned at this upper space, be evenly equipped with a plurality of pores 9 on the dividing plate 8, in this example, pore 9 is evenly to distribute on the circumference in the center of circle at the longitudinal shaft with head 1, and quantity is 3.In other embodiments, the quantity of pore also can be uniform 4, or selects evenly to be provided with in the mode that is fit to the pore of suitable quantity according to the size of head size.

When Pneumatic lift of the present utility model is used for the slag charge of transporting water, also can be provided with circulating pipe 6, float to make the slag charge that precipitates in the water by stirring action.Circulating pipe 6 is arranged on head 1 outside, and the suction inlet of the water outlet of circulating pipe 6 and head 1 is set up in parallel.This structure setting is compared with the structure that water pipe is located at head inside, has increased the inner space of head.

In preferred embodiment of the present utility model, structure same as the previously described embodiments is no longer repeated.In addition, the internal surface of head 1 also is provided with the wear-resistant ceramic layer, to improve the wear resistance of head, improves the working life of device.

In another preferred embodiment of the present utility model, head 1 and riser 3 are made by rare-earth alloy material, to improve the wear resistance of head and riser, improve the working life of device.

The working principle of strength lifting device of the present utility model is: ON cycle water pipe at first, the slag charge in bottom precipitation is floated, at the fixed time after, close circulating pipe.Open compressed air hose then, pressurized air imports from compressed air hose 2, be introduced into the upper space of head, enter the lower space of head again via pore uniform on the dividing plate, thereby make the head 1 and the discharge port of guiding gutter 4 form certain pressure reduction, gas flows to guiding gutter 4 through riser 3 from head 1, make the suction inlet place of head 1 form negative pressure, thereby slag charge is inhaled into head 1 around the suction inlet, and rising to guiding gutter 4 through riser 3 with gas, the discharge port 7 natural overflows from guiding gutter 4 at last efflux.

The utility model is simple in structure, flexible arrangement, high working efficiency, and low, the long service life of energy consumption can adapt to various environment, can be widely used in metallurgy, mine, industry such as coloured, is to substitute slag stock pump ideal device.
