Description

A kind of ultrasonic filtration machine

Technical field

This utility model relates to filter plant field, particularly to a kind of ultrasonic filtration machine.

Background technology

Media filtrations many with tradition and filter element filtering compare, and owing to technical matters is simply still extensively applied in water filtration field, but the shortcoming that they exist also is well-known.

Medium filter (fiber ball filter as original): first, effluent quality is unstable, is carried out because it the most manually operates, and cleans not in time or the carelessness of operating process often makes pollutant penetrate filtering layer.Second, clean the most thorough, the mechanical retention that medium filter relies primarily between absorption and the filtering material particle of filter material surface micropore goes deimpurity, limited by technical conditions or operation level, cleaning function can only remove partial impurities in filter bed, thus the micropore of filter material surface gradually can be blocked by impurity and be formed and harden, have a strong impact on absorption and filter effect.3rd, floor space is big, and the bodily form is heavy, installs mobile inconvenience.4th, the cleaning of medium filter can produce substantial amounts of efflux wastewater, also brings along substantial amounts of power consumption simultaneously, the most just causes the waste of resource and the energy.

Security personnel's precision type filter (the skid accurate filter as applied in recent years): first; aquifer yield decay is serious; because filer element type filters belongs to dead-end filtration; the speed that filter element dirt is stifled when raw water turbidity is higher can be quickly; aquifer yield declines the most quickly; and then cause filter to build the pressure leakage, or cause following injected water pump due to water deficiency strenuous vibration or shutdown.Second, operating cost is high, and filter element great majority are single use, needs manually to change after filter element occurs dirt stifled, often changes filter element equipment operating cost due to needs the highest, increases operator's labor intensity simultaneously.3rd, continuous service ability is poor, if needing continuous operation at least just can realize running continuously with more than two filter parallel connections.

Existing filter does not possess reliable high pressure backwashing function, so cleaning thorough after drainage screen dirt is stifled, makes drainage screen flux to recover, and therefore causes the filter cannot be properly functioning.

Detailed description of the invention

Describe preferred implementation of the present utility model below in conjunction with the accompanying drawings in detail.

nullFig. 1、Fig. 2 and Fig. 3 shows detailed description of the invention of the present utility model: a kind of ultrasonic filtration machine，Including Rose Box 1，The bottom of this Rose Box 1 is provided with water inlet 2 and outlet 3，The bracing frame 4 supporting this Rose Box 1 it is provided with below Rose Box 1，The inside of described Rose Box 1 is socketed with dirt sucking tube 5 successively along axis、Filter tube 6 and backwash tube 7，The side of Rose Box 1 is provided with the backwash electric rotating machine 8 being connected with dirt sucking tube 5，Backwash electric rotating machine 8 is connected with Rose Box 1 by connecting sleeve pipe 20，The opposite side of Rose Box 1 is provided with the sewage draining exit 9 being connected with dirt sucking tube 5，The sidewall of filter tube 6 is made up of coarse strainer 10 and fie screen 11 two parts，The medial wall of Rose Box 1 is inwardly perpendicular to axis and is provided with baffle plate 12，Baffle plate 12 is slidably connected at the demarcation line of coarse strainer 10 and fie screen 11 relative on filter tube 6，Rose Box 1 is divided into two cavitys by baffle plate 12，It is filter chamber near coarse strainer 10 side，Near fie screen 11 side for cleaning chamber，Backwash tube 7 is arranged on cleaning intracavity，The lateral wall of described dirt sucking tube 5 is perpendicular to axis to being externally provided with the pollution-absorbing nozzle 13 communicated，Described backwash tube 7 sidewall is provided with folder chamber 15，The inwall of backwash tube 7 is perpendicular to the nozzle 14 that axis is provided inwardly with communicating.

Blowoff valve 16 it is provided with at sewage draining exit 9；Ultrasonic filtration machine also includes backwash high-pressure pump 17, and high-pressure pump is connected with backwash tube 7 and filter tube 6 respectively；Backwash high-pressure pump 17 is provided with connected differential pressure pickup 18；Connecting sleeve pipe 20 and be provided with controller 19, control chamber is connected with backwash electric rotating machine 8 and backwash high-pressure pump 17.

The former water of pressure is entered body by water inlet, first flows through coarse strainer in external pressure mode, filters larger particles impurity.Coarse strainer water outlet enters fie screen with inner pressed, fine impurities in trap water further, simultaneously, supersonic wave synchronism works, micro-bubble core in liquid is produced vibration, when acoustic pressure reaches certain value, continuation is expanded by bubble, the most suddenly close, in bubble, high temperature (5000K) high pressure (thousands of atmospheric pressure) is created when these minute bubbles collapse rapidly, and owing to the liquid at high speed around bubble pours bubble, and the liquid near bubble creates strong local shock, also form the High Temperature High Pressure of local, thus create ultrasonic sterilization, clean, pulverize, emulsifying, dispersion, promote a series of effects such as chemical reaction.Frequency integrates the multiple water treatment technology such as advanced oxidation, burning, supercritical oxidation at the ultrasound wave of more than 20KHz, not only can prevent filter screen dirt from blocking up, extend the filter screen backwash cycle, has sterilization significantly and the function of degradation of organic substances simultaneously.

nullAlong with the pollutant various in filter medium accumulation inside fie screen，Filtration channel is blocked，Intake-outlet pressure reduction is gradually increased，When pressure reduction reaches pre-set value，The pressure difference signal detected just is converted into the current signal of 4-20mA by the pressure difference transmitter being connected to intake-outlet，Pass to control system，Backwash frequency also can carry out presetting by the time simultaneously，When reaching pre-set value between when running，System starts stroke motor and backwash high pressure pump automatically，Now actuating device drives the contaminants collector equipped with suction nozzle to do rotation and horizontal back and forth movement inside filter screen，Simultaneously，Outside filter screen，High pressure back purge system and blowdown apparatus synchronization action，And in corresponding relation，Do not interrupt properly functioning on the premise of，Only by sub-fraction product water，Filter screen is carried out high pressure backwash，Backwash water passes through filter screen，Contaminants collector is immediately wicked into by suction nozzle together with the impurity peeled off on filter screen，Deliver to blowdown room，Finally discharged by sewage draining exit.

This filter of this utility model structure is mainly used in purifying water purposes, particularly higher to water quality requirement microfiltration field, in the removable water of major function, the impurity such as silt, clay, rust, float, algae, biological clay, corrosion product, macromole antibacterial, Organic substance and other molecule, reaches the purpose of purification of water quality.Clear water and the sewage through pretreatment can be processed in terms of low permeability oil field reinjected water process.

Above-described is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
