Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, differential pressure filtering machine structure described in the utility model, comprises filter box 1, and described filter box 1 is arranged on base 4.In this filter box 1, be provided with filter, derived by described delivery port 6 again after the former water that described water inlet 5 imports falls impurity via described metre filter.
The utility model also comprises impurity and pulverizes emulsification generator, and described impurity is pulverized emulsification generator and the impurity be attached on filter is carried out pulverizing emulsification.
Specifically, the utility model also comprises pressure reduction backwash unit, carries out backwash when the pressure differential of described pressure reduction backwash unit between water inlet 5 and delivery port 5 reaches preset value to described filter; Or described pressure reduction backwash unit carries out backwash to described filter within the time interval of presetting.
According to foregoing, in the utility model, described pressure reduction backwash unit specifically comprises the pressure difference transmitter (not shown) being divided into water inlet 5 and delivery port 6.Also comprise controller 2, the pressure difference detection signal of described pressure difference transmitter is linked into described controller 2.Also comprise backwash high pressure pump 9, described controller 2 controls described backwash high pressure pump according to pressure difference detection signal and carries out backwash (this backwash high pressure pump 9 can arrange backwash pipe 13, and this backwash pipe 13 is linked into filter place and carries out backwash) to the impurity on described filter.And also comprise dirt-collecting unit, described dirt-collecting unit is collected filter being backwashed the impurity got off.
As shown in Figure 3, Figure 4, described dirt-collecting unit comprises the pollution-absorbing nozzle 14 being positioned at backwash high pressure pump (i.e. backwash pipe 13) offside, the blowdown room 15 be communicated with described pollution-absorbing nozzle 14 and drives described pollution-absorbing nozzle 14 to make the drive unit 3 of horizontal back and forth movement and rotary motion simultaneously.Described drive unit 3 drives pollution-absorbing nozzle 14 to rotate inside filter and horizontal back and forth movement simultaneously, and, the backwash high pressure pump (i.e. backwash pipe 13) be positioned at outside filter carries out high pressure backwash to filter, backwash water is through filter, be drawn into rapidly blowdown room 15 together with the impurity that filter is peeled off by pollution-absorbing nozzle 14, and after discharge through sewage draining exit 7.Said structure when not interrupting normal operation, only can rinse filter with regard to realizing by sub-fraction product water, thus guaranteeing the filter effect of filter.
As shown in Figure 3, Figure 4, described filter is between the shell body and the shell body of blowdown room 15 of described filter box 1.Described filter specifically comprises the coarse filter 11 being positioned at water inlet 5 side and the fine cleaner 12 being positioned at delivery port 6 side, and described former water filters through coarse filter 11 after being entered by water inlet 5, then is derived by delivery port 6 after fine cleaner 12.Between the shell body of described pollution-absorbing nozzle 14 then in blowdown room 15 and fine cleaner 12; Described backwash high pressure pump (i.e. backwash pipe 13) is between the shell body and fine cleaner 12 of filter box 1.
In the utility model, described impurity is pulverized emulsification generator and specifically be can be supersonic generator, and this supersonic generator and described controller 2 are electrically connected; Described controller 2 starts according to the external command received or stops described supersonic generator.
Former water enters filter box 1 via water inlet 5, first flows through coarse filter 11 in external pressure mode, with filtering larger particles impurity.Coarse filter 11 water outlet enters fine cleaner 12 with inner pressed, the fine impurities in further trap water.Simultaneously, supersonic generator works asynchronously, vibration is produced to the micro-bubble core in liquid, when acoustic pressure reaches certain value, continuation is expanded by bubble, then close suddenly, in bubble, high temperature (5000K) high pressure (thousands of atmospheric pressure) is created when these minute bubbles collapse rapidly, and because the liquid at high speed around bubble pours bubble, and create strong local shock in liquid near bubble, also form the HTHP of local, thus create ultrasonic sterilization, cleaning, pulverize, emulsification, 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 ultrasonic wave of more than 20KHz, filter dirt not only can be prevented stifled, extend the backwash cycle of filter, have the function of sterilization significantly and degradation of organic substances simultaneously.
Along with the accumulation of pollutant (or impurity) various in filter medium inside fine cleaner 12, filtration channel is blocked, intake-outlet pressure differential increases gradually, when pressure differential reaches pre-set value, the differential pressure signal detected just is converted to the current signal of 4-20mA by the pressure difference transmitter being connected to intake-outlet, and pass to controller, control described backwash high pressure pump by controller and backwash is carried out to the impurity on described filter.Meanwhile, backwash frequency is also undertaken presetting by the time, and when reaching pre-set value when running, controller starts drive unit and backwash high pressure pump automatically, to carry out high pressure backwash to filter.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
