Abstract
The utility model provides a backwashing device for drum type micro-filters, for getting fresh water from a fresh water channel of the drum type micro-filter to backwash a filter cylinder. The backwashing device comprises an air-dissolving water pump and a backwashing water pipe, wherein the air-dissolving water pump communicates with the fresh water channel; one end of the backwashing water pipe is connected with the air-dissolving water pump while the other end stretches to be the position above the filter cylinder; the lower part of the section, above the filter cylinder, of the backwashing water pipe is provided with a plurality of backwashing nozzles. According to the backwashing device for drum type micro-filters, the fresh water and air are mixed to form air-dissolving water through the air-dissolving water pump, oil contamination is blown off from a filter screen, water can wash away suspended matter particles better, good washing effect to the filter screen can be achieved, and thereby filter effect of the filter cylinder can be ensured.
Description
Technical field
The utility model relates to sewage water filtration technical field, relates in particular to a kind of back purge system for rotary drum micro-filter.
Background technology
In municipal wastewater and trade effluent, contain a lot of superfine suspended particles, sewage is purified and first will filter out these superfine suspended particles, the sewage disposal technology that a kind of filter efficiency is higher is realized by rotary drum micro-filter, this rotary drum micro-filter is sewage to be passed into the rotatable filter cylinder that filter net sheet is installed clear water and suspended particle are separated, filter cylinder comprises filter net sheet, in use procedure, on filter net sheet, can deposit a large amount of suspended particles, in order to guarantee filter quality, need to filter net sheet, rinse by backwash shower nozzle, thereby residue punching is fallen in a waste collection groove, but the backwash effect of existing back purge system is unsatisfactory, mainly except suspended particle, also can residual a certain amount of greasy dirt on filter net sheet, light has water backwashing, the dirt remaining on filter net sheet cannot be dropped in waste collection groove completely, thereby cause the filter effect of micro-filter to decline.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the not good problem of backwash effect of back purge system in prior art, the utility model provides a kind of back purge system for rotary drum micro-filter to solve the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: a kind of back purge system for rotary drum micro-filter, for the Rinsing Area from described rotary drum micro-filter, obtain clear water filter cylinder is carried out to backwash, comprise dissolved air water pump and backwash water pipe, described dissolved air water pump is communicated with described Rinsing Area, one end of described backwash water pipe is connected with described dissolved air water pump, one end extends to the top of described filter cylinder in addition, and the bottom that described backwash water pipe is positioned at the part of described filter cylinder top offers a plurality of back flushing nozzles.
As preferably, in order to improve the backwash area to filter cylinder, improve backwash effect, described back flushing nozzle is stainless steel umbrella shaped spray nozzle, for dissolved air water being to umbrella shape, towards described filter cylinder, sprays.
Concrete, described dissolved air water pump comprises dissolving and water pump, described water pump is low-flow high-lift water pump.
The beneficial effects of the utility model are, this back purge system for rotary drum micro-filter, by dissolved air water pump, clear water and gas are mixed to form to dissolved air water, by gas, greasy dirt is blown off from filter net sheet, water can rinse suspended particle better, reach the good developing result of filter net sheet, thus the filter effect of assurance filter cylinder.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is that the utility model is for the structural representation of the optimum embodiment of the back purge system of rotary drum micro-filter.
In figure 1, dissolved air water pump, 2, backwash water pipe, 3, filter cylinder, 4, stainless steel umbrella shaped spray nozzle.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model provides a kind of back purge system for rotary drum micro-filter, for the Rinsing Area from rotary drum micro-filter, obtain clear water filter cylinder 3 is carried out to backwash, comprise dissolved air water pump 1 and backwash water pipe 2, dissolved air water pump 1 is communicated with Rinsing Area, dissolved air water pump 1 comprises dissolving and water pump, water pump is low-flow high-lift water pump, one end of backwash water pipe 2 is connected with dissolved air water pump 1, one end extends to the top of filter cylinder 3 in addition, the bottom that backwash water pipe 2 is positioned at the part of filter cylinder 3 tops offers a plurality of stainless steel umbrella shaped spray nozzles 4, this back purge system for rotary drum micro-filter is extracted the clear water of Rinsing Area out by water pump, be mixed to form dissolved air water with the gas in dissolving, dissolved air water enters backwash water pipe 2 and is umbrella shape towards filter cylinder 3 ejections by stainless steel umbrella shaped spray nozzle 4, the greasy dirt and the suspended particle that complete being deposited on filter net sheet carry out backwash.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
