Description

Prevent blocking submersible pump

Technical field

The utility model relates to a kind of water pump, and more particularly, it relates to a kind of submersible pump.

Background technique

The pump housing need be put into water during submersible pump work, the bottom of the pump housing is provided with filter cylinder, mine water is by after filter cylinder filtering particles impurity, be extracted and discharged by water outlet, because long-term work there will be filter cylinder stopping state, once filter cylinder blocking makes to draw water, water outlet stops water outlet, one section of water column can be stayed when next stops pumping in pump just to there will be no-load condition because the impeller of motor also in working pump also rotates in continuation, because submersible pump is by water cooling itself but the impeller be not immersed in water rotates heat in atmosphere produces in a large number, but mechanical seal can be caused to damage thus cause in pump owing to there is no water cooling to leak, transmission shaft also can be made to fracture or impeller is killed and then damaged motor if idle time is long, the whole pump housing is damaged, cause huge economic loss.

The submersible pump that the Chinese patent that application number is 201420048585.X provides, it utilizes current impeller to rotate, impeller blade is provided with cleaning hairbrush, while vane rotary, hairbrush rotates cleaning filter cylinder, although this kind of technological scheme solves the problem of filter cylinder blocking, but bring new problem simultaneously, clear up impeller while drawing water is rotating the water that makes into always and under the effect of clearing up impeller, produce centrifugal action impact to intake efficiency, and the power of motor provides for making water upwards extract originally, but now water also will be supplied to the acting of cleaning wheel rotation, according to principle of conservation of energy, compare original power without needing motor to provide larger during cleaning impeller, taking out identical water in same time needs consumption more electric.

Model utility content

For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of prevents blocking submersible pump, and when filter cylinder blocks, just filter screen is cleaned in work, does not affect normal pumping, reduces power consumption, prevents the zero load heating damage pump housing of pump simultaneously.

For achieving the above object, the utility model provides following technological scheme:

One is anti-blocks submersible pump, comprise the pump housing, the bottom of the described pump housing is provided with filter cylinder, the sidepiece of described filter cylinder is provided with by-pass port, described by-pass port is provided with bypass valve, anti-blocking component is provided with in described filter cylinder, described anti-blocking component comprises water wheels, described water wheels are rotatably connected with bottom filter cylinder by rotating shaft, described water wheels are just arranged by-pass port, the blade of described water wheels all with the parallel to an axis of filter cylinder, the circumference of described water wheels is connected with pendulum, the inwall of described filter cylinder is provided with and produces shake projection, and it is protruding that described pendulum knocks product shake in water wheels rotary course.

By adopting technique scheme, when filter cylinder does not block, mine water filters through filter cylinder, extracted by submersible pump, filtering particles impurity, when granule foreign runs up to a certain degree at cartridge exine, when causing filter cylinder to block, by filter cylinder water inlet reduced capability or block completely, and pump body is still according to set power operation, make to produce powerful negative pressure in the pump housing, when negative pressure is greatly to when being enough to make bypass valve open, bypass valve is opened, mine water pours in the pump housing through by-pass port, just the water wheels of by-pass port are rotated under current drive, drive pendulum to rotate thereupon, under centrifugal action, interference range touches to filter cylinder inwall, the product arranged with filter cylinder inwall shake protruding constantly collide to produce shake, impurity outside filter cylinder is shaken off, it is made to be difficult to attachment, until filter cylinder is cleaned to conducting, pump body negative pressure weakens to being not enough to make bypass valve conducting, water wheels stop operating, scale removal process stops, prevent the blocking of filter cylinder thus, what be different from prior art is, anti-blocking component only just works when filter cylinder blocks, when filter cylinder normally works, because blade and cartridge axis are to be arrangeding in parallel, current cannot drive water wheels to rotate, and do not consume extra energy.

As concrete technological scheme of the present utility model, the protruding axis in strip along filter cylinder of described product shake is arranged, and in filter cylinder circumferential array many.

By adopting technique scheme, product shake in filter cylinder circumferential array is protruding, when water wheels rotate as collision body, collide continuously with the pendulum of rotary oscillation, make filter cylinder produce vibrations, simultaneously, collision is produced shake and is cleared up filter cylinder, certainly will impact the structural strength of filter cylinder, and many are produced the protruding setting of shake, the structural strength of filter cylinder can also be improved, increase the service life.

Concrete, described pendulum comprises center of gravity portion, and described center of gravity portion is coated with elasitic layer.

By adopting technique scheme, center of gravity portion ensures that pendulum produces enough large centrifugal force under water wheels drive, clashes into the inwall of filter cylinder, the setting of elasitic layer, when making pendulum and produce the collision of shake projection, reduces the loss that rigid collision is brought, increases the service life.

Further, the profile of described elasitic layer is spherical in shape.

By adopting technique scheme, spherical elasitic layer is more even to producing the protruding shock of shake, reduces and mutually collides the wearing and tearing brought.

Compared with prior art, the utility model prevents that the advantage blocking submersible pump is: by arranging bypass valve and anti-blocking component, only when filter cylinder blocks, anti-blocking component is just made to coordinate to produce with filter cylinder inner structure and shake, cleaning filter cylinder, intermittent cleaning, reduces energy consumption.
