Description
Technical field
This utility model is related to water pump field, more particularly, to a kind of multistage filtering anti-blocking immersible pump.
Background technology
, as a kind of universal machine, it is of many uses for pump；With the development evolvement of water pump, occur in that various water
Pump, immersible pump is the one kind inside pump.Immersible pump is different from common water pumper, and immersible pump is that motor is dived with water pump direct-connected integrated
Enter and work under water in water, well immersible pump, scope of operation immersible pump, submersible sewage pump, sand-discharging submerged pump, vertical pump for mine etc. can be divided into.
The frame for movement of immersible pump is: is made up of water pump, submersible motor, water-supply-pipe and controlling switch four major part.The work of immersible pump
Principle is: before turn on pump, must be hydraulically full in suction tube and pump.After turn on pump, impeller high-speed rotation, liquid therein is with blade
Rotate together, under the influence of centrifugal force, fly away from impeller and outwards project, the liquid of injection spreads indoor speed in pump case and gradually becomes
Slowly, pressure is gradually increased, and then from pump discharge, discharge pipe flows out.Now, at blade center due to liquid be thrown toward around and
Formed not only there is no air but also there is no the vacuum low-pressure area of liquid, the liquid in liquid pool in the presence of the atmospheric pressure of pond face, through suction
Pipe flow enters in pump, and liquid is exactly so continuously to be pumped up from liquid pool and continuously flow out from discharge pipe.
In prior art, the structure of submerged pump water-sucking filter screen device is mainly inclusion and is fixedly connected under the immersible pump pump housing
Screen cover on square water inlet, but in water, contain various impurity, even if the impurity that filter mantle blocks greater particle size enters the pump housing,
Also smaller impurity cannot be avoided, fine impurities are sucked in pump also can make impeller stuck, cause mechanical disorder to frequently occur,
Impact is normal to be used.Native sewage water medium-length fibre debris exist in a large number, for example north pocket, leaveves etc., are entered with single screen cover
Row filters still can make long fibre debris be deposited in water inlet, cause filter mantle to block or make long fibre debris by strength suction pump
Body, causes impeller to block.Pump can make pump cisco unity malfunction once being blocked, or even motor damage.
The utility model patent of Patent No. 201220693628.0 discloses a kind of new no blocking blade impeller blowdown
Pump, is provided with blade pump cover on the pump housing, is provided with blade impeller on bearing, and described blade impeller is provided with the lobus sinister face edge of a knife and the right side
The blade face edge of a knife, enters fashionable in crude fibre, and the lobus sinister face edge of a knife and the lobus dexter face edge of a knife form cutting with blade pump cover, make water pump no stifled
Plug.This patent makes it diminish by cutting long fibre, thus avoiding the obstruction that pump is caused, cutting effect is relatively in actual applications
Difference, the stronger article of the toughness such as some plastic bags are more difficult to be chopped into, and anti-blocking effect is undesirable.And, the impeller with the edge of a knife
When debris are cut, debris can wear and tear impeller, even result in impeller failure, so that the service life of immersible pump is reduced.
Utility model content
The purpose of this utility model is to provide a kind of multistage filtering anti-blocking immersible pump that can exclude debris in time, energy
Enough avoid the particulate matter of different-grain diameter or long fibre debris to enter immersible pump, effectively prevent drainage screen or impeller blocked, thus
Avoid mechanical disorder.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of multistage filtering anti-blocking immersible pump, including submersible motor and the pump housing, the pump housing is provided with water inlet and water outlet
Mouthful, be provided with the pump chamber being connected with water inlet, outlet in the pump housing, in pump chamber, be provided with impeller, described submersible motor defeated
Shaft is connected with impeller, and described water inlet is provided with horn mouth, is provided with drainage screen in horn mouth, the row of being provided with outside drainage screen
Dirty blade, described water inlet is also equipped with decelerator, and the input shaft of decelerator is connected with the output shaft of submersible motor, decelerator
Output shaft is fixedly connected with blowdown blade.
As preferred version of the present utility model, described drainage screen is multiple, between multiple drainage screen parallel, spaced-apart are certain
Away from setting, outside each drainage screen, it is provided with a blowdown blade；Sewage draining exit is provided with horn mouth.
As preferred version of the present utility model, each blowdown blade is all obliquely installed, and blowdown blade is in center
Incline direction is parallel to the rotational plane of blowdown blade, and is gradually transitions the side perpendicular to blowdown blade rotational plane outward
To.
As preferred version of the present utility model, the number of blade of each blowdown blade is four.
As preferred version of the present utility model, the drainage screen mesh diameter of described horn mouth big opening end is 1-2cm, loudspeaker
The drainage screen of mouth big opening end is with diameter greater than the drainage screen mesh diameter at horn mouth osculum end.
This utility model has the advantages that
1st, this utility model is provided with horn mouth in water inlet, is provided with multistage filtering net in horn mouth, and sewage passes through
During drainage screen, the particulate matter of different-grain diameter and long fibre debris are foreclosed one by one, it is to avoid after the impurity in water enters the pump housing
Cause the situation that impeller blocks to occur, ensure the normal work of immersible pump.Drainage screen is arranged on horn mouth, negative in impeller
Under pressure effect, water inlet produces larger negative pressure, and bell-mouthed big opening end pressure can be smaller.Thus, reduce drainage screen
Being directly installed on water inlet causes the absorption such as long fibre such as plastic bag to cause the situation of drainage screen blocking to occur on drainage screen.
The rotation of blowdown blade, can greatly avoid debris to be attracted on drainage screen and cause drainage screen to block, also block miscellaneous
Matter enters back into the chance of the pump housing it is ensured that the normal work of immersible pump.
2nd, drainage screen is multiple, multiple drainage screen parallel, spaced-apart one determining deviation settings, is provided with outside each drainage screen
One blowdown blade, and, the drainage screen of horn mouth big opening end is with diameter greater than the drainage screen mesh diameter at horn mouth osculum end.Interior
Layer drainage screen can filter out the less debris of particle diameter, be prevented effectively from debris and enter immersible pump, causes impeller to block, impact diving
Pump normal work.Each blowdown blade is all obliquely installed, and the incline direction in center for the blowdown blade is parallel to blowdown blade
Rotational plane, and be gradually transitions the direction perpendicular to blowdown blade rotational plane outward.So, debris have by from drainage screen
Centre is discharged to the trend at drainage screen edge, then discharges from sewage draining exit, it is to avoid impurity is deposited on drainage screen makes drainage screen block.
