Description
(1) technical field
The utility model relates to a kind of filter.
(2) background technology
Sand filter is that graininess, flocculence suspension are filtered the important device of removing from liquid.Sand filter is after using a period of time, and granular or cotton-shaped impurity can be trapped in the filter sand, and is untimely with the impurity place to go, will have influence on the rate of filtration and filter quality.For removal of contamination, will carry out backwash to sand filtering device.Existing sand filtering device when carrying out backwash, must stop to filter.Stop to filter, will influence normally carrying out of whole process of production, reduce production efficiency.In order to guarantee carrying out continuously of filter process, usually standby filter to be set, replace filter operation.Also need to be provided with the backwash pond in addition.Therefore its equipment investment is higher, and floor space is bigger, and operating cost is higher.
(3) summary of the invention
The purpose of this utility model is to provide recirculation system sand filter device in the little continous way of a kind of efficient height, floor space.The purpose of this utility model is achieved in that it comprises housing, be filled in the filter sand in the housing, bottom in housing is provided with cyclone water distributor, cyclone water distributor links to each other with water inlet pipe, there is a sand extraction tube at middle part in housing, the compressed air inlet pipe is arranged at the bottom of housing, the air nozzle at compressed air inlet pipe mouth place is relative with the end opening of sand extraction tube, the suitable for reading of sand extraction tube extend in the washed-out sand groove that has adjustable backwash mill weir, the wrong ring type sand-washing device of the upper end outer setting of sand extraction tube, adjustable backwash mill weir communicates with wrong ring type sand-washing device, and adjustable backwash mill weir connects the backwash effluent trough, water leg is arranged at the top of housing, has outlet pipe on the water leg.Advantage of the present utility model is: be provided with the internal-circulation type back purge system of being made up of sand extraction tube, compressed air inlet pipe, adjustable backwash mill weir, wrong ring type sand-washing device, backwash effluent trough in sand filtering device, when filtering, the bottom bigger filter sand of impure amount is mentioned from sand extraction tube, enter adjustable backwash mill weir, wrong ring type sand-washing device carries out backwash.This backwash process carries out with filter process simultaneously continuously.Therefore this sand filter can carry out the serialization filtration incessantly, has high filtration efficiency.Simultaneously do not need to be provided with the backwash tank and saved coagulation-settlement process, the floor space of filter is reduced greatly, reduced the equipment investment expense.Can guarantee that filter sand is in good filtration state all the time, guaranteeing has the good rate of filtration and filter effect, can reduce the dosage of processing procedure, reduces operating cost, and its dosage is saved 20-30% than conventional water treatment procedure.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of wrong ring type sand-washing device;
Fig. 3 is the structural representation of umbrella formula cloth sand cap.
(5) specific embodiments
For example the utility model is done more detailed description below in conjunction with accompanying drawing:
In conjunction with Fig. 1.Its composition comprises housing 1, be filled in the filter sand 2 in the housing, bottom in housing is provided with cyclone water distributor 3, cyclone water distributor links to each other with water inlet pipe 4, there is a sand extraction tube 5 at middle part in housing, compressed air inlet pipe 6 is arranged at the bottom of housing, the air nozzle at compressed air inlet pipe mouth place is relative with the end opening of sand extraction tube, the suitable for reading of sand extraction tube extend in the washed-out sand groove 7 that has adjustable backwash mill weir, the wrong ring type sand-washing device 8 of the upper end outer setting of sand extraction tube, adjustable backwash mill weir communicates with wrong ring type sand-washing device, adjustable backwash mill weir connects backwash effluent trough 9, have backwash water pipe 10 on the backwash effluent trough, water leg 11 is arranged at the top of housing, has outlet pipe 12 on the water leg.The course of work of the present utility model is described below: the former water through adding medicament enters cyclone water distributor through water inlet pipe.Current flow out after filter course filters from the aperture of water distribution branch pipe, and the suspension in the former water, is retained down by filter sand by in the process of filter sand filter course from bottom to top, and filtered water rises to water leg, enters tank through outlet pipe, finishes filter process.When finishing filter process, compressed air feeds sand extraction tube, drives the more filter sand of bottom impurity trapped and together rises, and the mixture that is raised falls into the washed-out sand groove from the sand extraction tube top, and sand grains enters wrong ring type sand-washing device with current.Be higher than adjustable backwashing water water outlet weir plate water level owing to filter water outlet mill weir water outlet water level, under the effect of the water-head of filtering water outlet and backwash water outlet, once flushing water and the secondary flushing water in the sand-washing device in the sand extraction tube are discharged by the backwash water pipe that has on the backwash effluent trough, and because the proportion of filter sand is bigger, the filter sand of cleaning under the effect of gravity turns back to filtering layer.
Second kind of embodiment of the present utility model is: on the basis of embodiment 1, carry sand water pipe 13 in the setting of the bottom of sand extraction tube.Equipment can be full of sand in the sand extraction tube after stoppage in transit a period of time, and these sands are depended merely on compressed-air actuated strength and are difficult to it is in time mentioned.If untimely mentioning, will influence normally carrying out of backwash and filtration.After the sand water pipe is carried in setting, can open when needed and carry the sand water pipe, aqueous vapor cooperates carries sand.To carry the sand water pipe again after stable closes.The normal operation of assurance equipment.
The third embodiment of the present utility model is: on the basis of embodiment 1 and embodiment 2, umbrella formula sand arranging device 14 is set under wrong ring type sand-washing device.After umbrella formula sand arranging device is set,, fall earlier on the umbrella formula sand arranging device, after umbrella formula sand arranging device is evenly distributed, fall into filtering layer again, guarantee being evenly distributed of filter sand from the filter sand of cleaning that wrong ring type sand-washing device falls.
The 4th kind of embodiment of the present utility model is: in conjunction with Fig. 3, on the basis of embodiment 3, have the hole in different apertures on the umbrella formula sand arranging device.Can guarantee being more evenly distributed of filter sand like this.
The 5th kind of embodiment of the present utility model is: steam vent siphon destructing tube 15 is set on water inlet pipe, has check-valves on the steam vent siphon destructing tube.Equipment can guarantee the normal circulation of filter sand when moving continuously, when equipment was out of service, because the water level of filter inside is higher than one-level pumping plant water level, the siphonage of formation can oppositely be drawn back pumping plant by water-distributing device with filter sand.The steam vent siphon destructing tube the generation that can prevent this phenomenon effectively is set.
The 6th kind of embodiment of the present utility model is: in the bottom of filter sand layer knockout cover 16 is set.
