Abstract
A kind of centrifugal self-suction sewage pump of backwater hole anti-clogging, by the pump housing, impeller, 2, pump shaft, suspension and sucking check valve composition, there are suction inlet, suction passage, outlet, air-water separation chamber and backwater hole in pump housing inner cavity, and a filter device is arranged immediately ahead of backwater hole, which forms by holder and mounted on the pivoted housing of rack bore, the outer circle of pivoted housing is equipped with filter screen, filter screen is made by stainless steel sheetmetal, and medium enters back into backwater hole after filtering, avoids the blocking of backwater hole.Scraper plate is also equipped on holder.When handle drives pivoted housing rotation, the impurity that the impurity accumulated on filter screen falls into sedimentation basin through the scraping of scraper plate, therefore accumulated on filter screen need not shut down and can remove.If the impurity content in sewage is more, the external part of pivoted housing can also be driven by worm reduction gear to be rotated, and can without a break be cleared up filter screen.The sediment of sedimentation basin can be cleared up periodically through slag notch.
Description
Technical field
The present invention relates to a kind of centrifugal pump, especially a kind of centrifugal self-suction sewage pump of backwater hole anti-clogging
Background technology
Well-known Ordinary Centrifugal Pumps, if sucking liquid level is under impeller, when startup, should pour water in advance, very inconvenient.
For the water in pump, suction line import needs to fill bottom valve, and when pump work, bottom valve causes prodigious hydraulic loss.So-called self-priming
Pump, is exactly to be not required to pour water (starting for the first time still after installation needs to pour water) before activation, by short-time running, leans on pump itself
Effect, you can water is drunk up, input normal work.
Gas-liquid mixed self priming pump due to the pump housing special construction, water pump stalling after, have a certain amount of water in the pump housing,
It pumping after being again started up due to impeller turning effort, the air and water of suction line are sufficiently mixed, and are discharged to air-water separation chamber,
The water of the gas overflowing on air-water separation chamber top, lower part returns to impeller through backwater hole, again mixed with the surplus air of suction line
It closes, until the gas in pump and suction line is all discharged, completes self-priming, and normal pumping.
This self priming pump with self-suction function need not install bottom valve in pipeline, need to only ensure in the pump housing before work
It contains and quantitatively draws liquid and can have the function of " primary drainage, lifelong self-priming ".Therefore pipe-line system is not only simplified, and improves labor
Dynamic condition, have the advantages that it is compact-sized, easy to operate, operate steadily, safeguard easy, efficient, long lifespan, in many necks
Domain is used widely, and is further used as sewage pump application.
It is well known that the self-priming effect of self-priming centrifugal pump is realized by backwater hole, self-priming centrifugal pump is applied to
After sewage, it is possible to make backwater hole that the area in channel be made to become smaller even because of the delay of impurity and block, lose self-suction function.
Invention content
It is an object of the invention to：For above-mentioned self-suction sewage pump there are the shortcomings that, propose one kind avoid backwater hole miscellaneous
The centrifugal self-suction sewage pump that matter blocks.
In order to achieve the above object, the centrifugal self-suction sewage pump of backwater hole anti-clogging of the present invention is mounted in the pump housing by the pump housing 1
Impeller 2 and the affixed pump shaft 3 of impeller 2 in 1 volute chamber, the suspension 4 of supporting pump shaft 3 form, and 1 inner cavity of the pump housing is additionally provided with sucking
Mouth, suction passage, outlet, air-water separation chamber and backwater hole 5, wherein suction inlet be provided with sucking check valve 6, it is special it
Be in：One filter device 7 is set in the front of backwater hole 5, filter device 7 is by the holder that is packed in 1 front baffle of the pump housing
It 8 and being formed mounted on 8 inner cavity of holder and co-axial pivoted housing 9, pivoted housing 9 is supported on two bearings 10 in holder 8, and
Its outer circle is equipped with filter screen 11, and the scraper plate 12 that sundries on filter screen 11 is deposited in for scraping is housed on holder 8.
The external part of pivoted housing 9 described in technical solution of the invention can be fixed with handle 13.
The position of installation filter screen 11 can be provided with multiple uniformly distributed on pivoted housing 9 described in technical solution of the invention
Radial window 14.
The surface that filter screen 11 can make for stainless steel sheetmetal in technical solution of the invention is formed with large number of
The cylindrical thin sleeve in radial filter hole.
The technical scheme is that a filter device 7 is arranged in 5 front of backwater hole, filter device 7 is by holder 8
It is formed with pivoted housing 9, the outer circle of pivoted housing 9 is equipped with filter screen 11, and medium enters back into backwater hole 5, avoids backwater hole 5 after filtering
Blocking.
Technical scheme of the present invention technical problems to be solved are：Prevent blocking of the impurity to backwater hole, it is ensured that sewage pump
It can normal self-priming and operating.
The positive effect of the present invention is：Medium enters the blocking that backwater hole can avoid backwater hole, heap after filter screen filtration
Long-pending impurity, which need not be shut down, to be removed.
