Abstract
The utility model relates to a groundwater purifying device with a porous medium. According to the groundwater purifying device, an aerating device which is a Venturi pipe is arranged at the bottom of a purifier, wherein high-pressure oxygen is poured into the Venturi pipe, so as to improve the aerating efficiency. An inclined baffle is arranged at an outlet in the upper part of the aerating device, and a discharging port is arranged at the lowest point of the inclined baffle; the filtered impurities are accumulated in the discharging port; the discharging port can be opened at fixed period so as to discharge the impurities. A porous medium is arranged at the upper part of the purifier, and the aperture of the porous medium is greatly reduced from bottom to top, therefore, the impurities with different granularities can be gradually filtered. According to the groundwater purifying device provided by the utility model, a filtering layer backwashing device is saved, and the groundwater purifying device is simple in structure; the Venturi pipe is adopted for aerating; compared with drop aerating, the groundwater purifying device disclosed by the utility model has the advantages that the aerating can be fully carried out and efficiency is high; and the porous medium is adopted for filtering, thus, the impurities with different granularities can be filtered at different levels.
Description
Technical field
The utility model relates to a kind of ground water cleaning device that has porous medium.
Background technology
Containing at subterranean water body is social precious water resource, and it not only can be used as water of productive use, also can be used as domestic water.In recent years; Along with the modern fast development of China's industrial or agricultural, the water resources of national most of areas has all received pollution in various degree, part Rural areas even the underground water severe contamination occurred; Such water not only can not use as domestic water; Even the standard of industrial and agricultural production water all do not reach, and if things go on like this will influence local people's quality of life and physical and mental health, the development and the social progress of restriction local economy.
In general, underground water all need carry out purifying treatment through purifier before extracting the entering pipe network.Though present purifier can carry out purifying treatment to underground water; But general structure design is more complicated all; Fine powder sand was deposited in the surface, filter tank easily when well started, and influenced the normal operation in filter tank, and decontamination effect improving and aquifer yield are all had very big influence; Cause pipe network water supply unstable, the water quality after the purification is poor.And flush time is long, and workload is bigger, and operational management comparatively bothers.
Summary of the invention
For solving the problem that exists in the prior art, the utility model provides a kind of ground water cleaning device that has porous medium, and a kind of ground water cleaning device that has porous medium is provided with cleaner, and the cleaner middle part is provided with sewage draining exit, and the bottom is provided with aerating apparatus; Aerating apparatus is a venturi tube, and the neck place of venturi tube is provided with the bilateral open tube.The bilateral open tube is for L shaped.For preventing that impurity from falling into venturi tube and stopping up the venturi tube neck, dust cap is set in the venturi tube exit.Exit, aerating apparatus top is provided with sloping baffle, and the top of cleaner is provided with porous medium; The aerating apparatus lower end links to each other with blower fan one side through pipeline, and blower fan opposite side inlet connects air trap.Sewage draining exit is arranged on the valley of sloping baffle.The cleaner top is provided with the constant voltage valve, guarantees the cleaner internal and external pressure balance.The porous medium hole that the utility model relates to reduces from the bottom to top gradually.Can filter out varigrained impurity gradually like this, avoid producing the single problem of bringing in filtering layer aperture:
1) aperture is excessive, makes filter effect relatively poor, and many impurity can flow out from pure water inlet, and is little to the processing help of water quality;
2) aperture is too small, can make that porous medium stops up, and makes porous medium forfeiture filtering function.
The utility model adopts following technical proposals: former water gets into cleaner through the driving of former water water pump from former water inlet; Air gets into air trap from gas inlet, is separated into nitrogen and oxygen, and wherein nitrogen is discharged from nitrogen outlet, and oxygen gets into cleaner through blower fan pressurization back.Former water and oxygen form complicated vapour-liquid admixture under the effect of venturi tube, utilize oxygen reaction to fall metallic impurity in the water etc.Along with the water level in the cleaner constantly raises, the water behind aeration arrives and through porous medium, utilizes porous medium that the solid matter in the water is stopped, discharges through the water purification water pump through the water purification of porous medium, can be used as the productive life water.Solid-state impurity falls back to sloping baffle through action of gravity, and sloping baffle has certain gradient, makes impurity be slipped to low level from a high position.When impurity accumulates to certain thickness, open sewage draining exit, impurity is discharged from sewage draining exit.
The utlity model has following advantage:
1) the utility model is simple in structure, good economy performance, and operation is convenient;
2) the utility model utilizes venturi tube to carry out aeration, compare with general drop water aeration, and better effects if, aeration is more abundant;
3) the utility model utilizes air trap to obtain the higher oxygen of purity, and pure oxygen aeration is compared with air aeration, and aeration efficient is higher;
4) the utility model utilizes porous medium to filter, and can realize varigrained contaminant filter in different levels;
5) the former water of the utility model feeds from the below, the output from the top, and filtering impurity directly falls back under the effect of gravity on the sloping baffle, can dispense the back-purge system of filtering layer, has reduced the complicacy of device.
