Description
Technical field
The utility model relates to a kind of suitable for conveying the environment protecting pump for having particle and fiber, in particular to a kind of main suitable
For conveying the non-clogging impeller of the solid with prehensile long fibre, bulky grain.Belong to slurry, sewage transport equipment and technology neck
Domain.
Background technique
Currently, pumping when conveying sewage dirt medium usually because being mingled with for example long plastic optical fibre of various long fibres, fiber crops in medium
The solid impurities such as fiber and bulky grain and cause operation block, thus influence pump passage capacity and operational efficiency, reduce pump
Reliability and service life；The fiber being wrapped on impeller not only reduce pump effective area of passage and and result in blockage, also need
Often shutdown processing, maintenance is frequent, to influence working efficiency and delay industrial production.Therefore, impeller of pump is realized without blocking, height
Efficiency and No-mistake Principle operation are current key technologies urgently to be solved.
Conveying solid-liquid environment protecting pump is a kind of pump and motor disjunctor, and slips into the pump class product to work under liquid simultaneously, and general
Horizontal pump or vertical sump pump are compared, and submersible sewage pump obviously has the advantages that the following aspects: 1. compact-sized, occupied areas
It is small；2. convenient to install and maintain；3. continuous operation time is long；4. the problems such as cavitation damage and water is not present；5. vibration noise
Small, motor temperature rise is low, no pollution to the environment.Just because of above-mentioned advantage, submersible sewage pump is increasingly valued by people, is used
Range it is also increasingly wider, by it is original be merely used to convey clear water till now can convey various sanitary sewages, industry
Waste water, construction site draining, liquid feed etc..In each row such as municipal works, industry, hospital, building, restaurant, water conservancy construction
It is played a very important role in each industry.
Common conveying solid-liquid environmental protection impeller of pump has binary channels and two kinds of wide vane type currently on the market.Both form leaves
The sewage pump of wheel is generally double shrouded wheel, the former is cumbersome, when lift it is higher (n sIt is small) and relatively low (n sLeaf inadequate conjunction when greatly)
Reason, efficiency is lower, and the latter's blade is easily wound, and influences blocking-free performance energy.The N pump of Fei Li company production and the production of Hai Site company
Inside Impeller in Screw Centrifugal Pump, because casting and processing request it is higher, the rare production of domestic manufacturer.And both types submersible sewage pump,
When conveying long fibre sewage dirt, it is be easy to cause blocking, maintenance down is frequent, influences to produce, and power is easy to surpass when big flow area
Load causes to burn motor.
Through retrieving, it has been disclosed that the patent submersible sewage pump of cutter device " have stirring " (application number:
201720904182.4), structure are as follows: be made of crushing cutting motor, connection frame, double-spiral cutter, cutting blade.Though the type
With cutter, but the consumption of power is increased from another point of view, efficiency is lower, also, increases cutter, import flow-passing surface
Product has certain reduction, flow decline.Through retrieving, it has been disclosed that patent " a kind of Anti-clog submersible sewage pump " (application number:
201010500477.8), the main cutter device of sewage pump has impeller, pump cover, bulge loop, impeller cover, cutting blade, ledger-plate, recessed
Slot, the action principle of the patent is similar with previous patent searching, all has cutter, stronger by your ability, but can disappear
Some impeller shaft power are consumed, motor is easy overload, low efficiency.Through retrieving, it has been disclosed that a kind of patent " water inlet knot of submersible sewage pump
(application number: 2015203449930.4), primary structure includes: the pump housing, outer filter screen, filtering net, accommodating chamber, water inlet to structure "
Mouth, extension, outer filter hole, limit base, interior filtering sky, limiting section, the outer filter screen are equipped with outer filter hole, the patent
Being is also an anti-block apparatus type.
Utility model content
The purpose of this utility model is that improving impeller cover in technique by improving front shroud of impeller structure, reduce
Manufacture difficulty of processing, improves the efficiency and anti-clogging of pump, increases No-mistake Principle and expand the range of operation of pump.
In order to realize above-mentioned purpose of utility model, the technical solution that the utility model is taken are as follows: one kind has for conveying
The environment protecting pump of particle and fiber, including motor and pump shaft, the pump shaft pass through pump cover after end be located in pump case, the pump case and
Pedestal connects, and impeller is equipped on the pump shaft in the pump case, and the impeller is equipped with front shroud and back shroud, the front shroud
Pedestal described in face is equipped with choma on the pedestal, and the blade on the impeller protrudes pedestal described in the front shroud face
Several distances in the end face of side, the part that the blade protrudes the front shroud are located in the choma.
In above scheme, the part that the blade protrudes the front shroud is flat by milling cutter milling, forms the sharp edge of a knife.
In above scheme, the blade is spiral centrifugal blade.
In above scheme, the impeller cast by double shrouded wheel after by falling part front shroud with lathe vehicle, described in realization
Blade protrudes several distances in end face of the front shroud.
In above scheme, it is 1 ~ 2mm that the blade, which protrudes the gap between the part of the front shroud and the choma,.
In above scheme, the impeller is mounted on the pump shaft by impeller nut.
The utility model has the beneficial effects that (1) with tradition without blocking diving pump impeller structure compared with, front shroud of impeller import
Axial direction part vehicle removes part front shroud, and vane nose face sharp in this way and choma form the rotation relationship of sound, not only reduce
Part impeller weight reduces the output of shaft power, cuts when improving the efficiency of submersible sewage pump, and conveying elongated fibers, bulky grain solid
Debris solids improves anti-entangling and blocking-free performance energy.(2) impeller form provided by the utility model, vehicle go to part
Front shroud reduces impeller weight, reduces casting and difficulty of processing, long fibre, passability and anti-fiber winding performance are good, are pumping
Each point can be safely operated on characteristic curve, to expand the application range of pump, long service life.
