Description

A kind of environment protecting pump for conveying with particle and fiber
Technical field
The present invention relates to a kind of suitable for conveying the environment protecting pump for having particle and fiber, in particular to one kind is primarily adapted for use in Convey the non-clogging impeller of the solid with prehensile long fibre, bulky grain.Belong to slurry, sewage transport equipment technical field.
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 area 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 is higher(n sIt is small)With it is relatively low(n sGreatly)When leaf inadequate conjunction 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 is:It is 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 Structure "(Application number:2015203449930.4), primary structure includes:The pump housing, outer filter screen, filtering net, accommodating chamber, water inlet 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.
Summary of the invention
It is an object of the invention to improve impeller cover in technique, reduce system by improving front shroud of impeller structure Difficulty of processing is made, the efficiency and anti-clogging of pump are improved, No-mistake Principle is increased and expands the range of operation of pump.
In order to achieve the above-mentioned object of the invention, the technical scheme adopted by the invention is as follows:One kind having particle and fibre for conveying The environment protecting pump of dimension, including motor and pump shaft, end is located in pump case after the pump shaft passes through pump cover, and the pump case and pedestal connect It connects, impeller is installed on the pump shaft in the pump case, the impeller is equipped with front shroud and back shroud, the front shroud face institute Pedestal is stated, choma is installed on the pedestal, the blade on the impeller protrudes the end of base side described in the front shroud face Several distances in face, 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.
Beneficial effects of the present invention:(1)Compared with tradition is without blocking diving pump impeller structure, front shroud of impeller import is axial Section 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, and chopping is fine when improving the efficiency of submersible sewage pump, and conveying elongated fibers, bulky grain solid Solids is tieed up, anti-entangling and blocking-free performance energy are improved.(2)Impeller form provided by the invention, vehicle remove part front shroud, drop Low impeller weight reduces casting and difficulty of processing, and long fibre, passability and anti-fiber winding performance are good, in pump characteristic curve Upper each point can be safely operated, to expand the application range of pump, long service life.
