Description

A kind of pre-cyclone of water pump

Technical field:

The invention belongs to pump equipment technical field, relate to a kind of water pump pretreatment unit, be installed on below pump intake, For building, agricultural, traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink, the industry such as municipal administration.

Background technology:

Water process be widely used in building, agricultural, traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink, The industries such as municipal administration, its processing procedure is for first collecting reprocessing, and during water inlet, in water, foreign material and mud etc. easily deposit and blocks up The water inlet of plug water pump causes water route not smooth, affects drain discharge, not only reduces treatment effeciency, reduces the water pump life-span, deposit Producing toxic and harmful and cause air and water pollution, and desilting is difficult, maintenance cost increases；In the prior art, to water The research for the treatment of technology is concentrated mainly in primary reinforcement process, two stage treatment, tertiary treatment or advanced treating, for pretreatment Technology still continues to use traditional preprocess method, such as: processing method or the combinations such as coarse rack, fine fack, setting pot and preliminary sedimentation tank Processing method, such as: be provided with manually or mechanically coarse rack or fine fack in water inlet front end and suspend or floating dirt for retaining, To protect water pump vane, it is to avoid water pump blocking or damage in impeller, it is ensured that water pump is properly functioning, but manually or mechanically grid takes up an area face Long-pending big, need cleaning and safeguard and be equipped with night shift room and other affiliated facilities in pumping plant；Widely used rotational flow grit chamber is Utilizing mechanical force to control fluidised form and flow velocity, accelerate the precipitation of sand grains, sand setting is effective, but mechanical dredge equipment is complicated, to construction Prescription is high, and floor space is big, is not suitable for residual organic matter in miniature water treatment plant or pumping plant and water；Chinese patent ZL200620034449.0 has been disclosed rotary running preprocessor, by top fixing element, outer cylinder body, screen filter, water outlet piece and The compositions such as taper storage bucket, the upper and lower part of cylinder is provided with the water inlet pipe and return duct being connected with cylinder tangent line, cylinder bottom respectively Being storage bucket and discharge pipeline, screen filter is fixed on the central authorities of cylinder, has filtrate collection case and outlet pipe bottom it, and its equipment is complicated, Investment height；In terms of Flow-rate adjustment, water treatment plant or pumping plant are typically provided converter, and traditional handicraft uses start-stop pump or frequency conversion Mode, the seriality of its technique is poor and frequent starting water pump causing trouble increases and maintenance cost increases.

Summary of the invention:

It is an object of the invention to the shortcoming overcoming prior art to exist, seek to design a kind of pre-cyclone of water pump, solve pre-place Desilting difficulty during reason, soil discharging facility is complicated, the problem of Flow-rate adjustment manufacturability difference, it is possible to reduce water treatment plant or pumping plant is built And if maintenance cost, economy is notable, increases pumping plant service life, reduces environmental pollution.

To achieve these goals, the pre-cyclone of the water pump that the present invention relates to, its agent structure includes basin body, overfall and lets out Mill weir, wherein sluice weir comprises inflow entrance, the first baffle plate, second baffle and deflector, and the basin body of hood configuration is open top Cylindrical shape, overfall is fixed on basin body top and connects as one with basin body transition type, and overfall is used for intercepting water inlet, with gear Having the inflow entrance of liquid on the sluice weir that mill weir integral type is connected, the left and right sides of inflow entrance integral type respectively is provided with the first baffle plate And second baffle, the first baffle plate and second baffle be tabular or V-type or U-shape structure, and the inner side of inflow entrance is provided with deflector, Deflector is spiral-shaped structure or is camber flow passage structure.

The operation principle of the present invention is: be fixedly installed in pumping plant below pump intake by water pump with pre-cyclone jacket-type, pump The water sent first flows through the pre-cyclone of water pump before entering water pump, and when pumping plant is properly functioning, continuous along with water level reduces, when When water level is less than overfall, water enters from the entrance of sluice weir, flows into basin body through deflector and produces in basin body and water pump rotation Turn the current that direction is identical, during whole water flow rotary, from sluice weir the bottom centre's flow velocity to basin body be gradually increased and Reach maximum in bottom, current drive in water in all substances entrance water pump, and then are discharged in supervisor's net, it is achieved that pumping plant Automatic pool cleaning, it is not necessary to install odor removal and clear pool equipment, it is to avoid pumping plant produces deposit and poisonous and harmful gas because shutting down water level height Body, reduces environmental pollution；When the source water level of water level decreasing to sluice weir, current have had certain flow velocity and water (flow) direction Identical with impeller direction of rotation, along with the continuation of water level reduces, fast to the rotation of current basin bottom center from sluice weir Degree is continually changing so that the discharge of water influx and water pump gradually matches, and when water level is minimum, discharge is minimum, Reach the effect of converter, it is achieved that flow automatic regulation and seriality technique, reduce investment of production.

The present invention compared with prior art, due to pre-rotation guide functions, it is possible under not closing flow of inlet water, it is achieved the most clear Pond and long-term, stable, Effec-tive Function, it is achieved flow automatic regulation and seriality technique；Its overall structure is simple, and volume is little, Taking up an area few, novel in design, investment of production is low, simple installation, keeps in repair convenient and environmental friendliness, have good economic benefit and Application prospect.
