Description
Technical field
The utility model relates to drinking water and produces required filter plant, relates in particular to the needed a kind of filter of drinking water production preliminary treatment.
Background technology
When flood-fighting, have abundant water resources, but the water that can directly drink does not safely then have.Be directly from river or pond, directly to obtain drinking water under such environment, and want to make full use of these water sources, produce drinking pure water, it is clean then to need corresponding water making device that the suspension in the muddy water is filtered, and so just can obtain meeting the drinking water of hygienic requirements.Processing procedure generally includes preliminary treatment and reverse osmosis process.Comprise sand filtration in the preliminary treatment, it is the first step of entire process process, and sand filtration is played with the big solid particle in the muddy water, such as the effect of removals such as silt, rubble, grass roots as the preliminary treatment link.The filler that sand filtration is used is a quartz sand, quartz sand is the very high ore of a kind of density, a lot of such quartz sands in the used equipment of sand filtration, are equipped with, therefore the sand filtration equipment volume is huge, profile is heavy, because sand filtering device is to be applied in open-air emergency set, so such structure certainly will influence use, cause the problem of difficult.The operation principle of sand filtration is to remove suspended particulate in the muddy water according to holding back principle.But when flood takes place in the water content of solid particle very high, therefore the very fast filter of quartz sand cuts a large amount of impurity in the sand filtration process, makes the sand filtering device filter efficiency slowly reduce, and need in time do backsurging operation to sand filtering device, normally carries out to guarantee sand filtration.The backsurging operation time is long, frequently carries out backwash and makes the sand filtering device cycle of operation shorten, and influences the supply rate of drinking water.
The utility model content
The technical problems to be solved in the utility model provides a kind of filter, simple in structure, volume is small and exquisite, in light weight, backwashing time is short.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this filter comprises housing, screen casing, connecting plate and loam cake, described housing bottom is provided with sand deposition hopper and is used for the feet of support housing, described sand deposition hopper bottom is provided with sand export, described hull outside is provided with water inlet, described enclosure interior is provided with baffle plate in the position of corresponding water inlet, described loam cake top is provided with delivery port and backwash mouth, described connecting plate is installed in loam cake inside, described screen casing is the semi-closed structure of inner hollow, its top is provided with the tubulose guide pin bushing that is used to connect, described screen casing top is installed on the connecting plate by guide pin bushing, the inside of described screen casing is by guide pin bushing and loam cake internal communication, and described loam cake and housing are movably connected.
As of the present utility model a kind of preferred, be threaded between described guide pin bushing and the connecting plate.Be convenient for changing screen casing like this.
As a kind of improvement of the present utility model, between described guide pin bushing and connecting plate, also be provided with sealing ring.Because the water quality of both sides is different inside and outside screen casing,, improve sealing property so install a seal member additional for guaranteeing not interpenetrate between the variant water quality.
The utility model adopts technique scheme, replaces the sand filtration equipment in the original preliminary treatment in drinking water is produced, and is simple in structure because of it, volume is small and exquisite, lightweight characteristics, makes its convenient in carrying, so be highly suitable for open-air the use; Secondly, this filter interior adopts screen casing to filter, and it is short that screen casing stops up the back backwashing time, thereby improved the drinking water speed of production.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is a kind of structure of filter schematic diagram of the utility model;
Fig. 2 is the screen construction schematic diagram of a kind of filter of the utility model;
System construction drawing when Fig. 3 is a kind of filter participation of the utility model work.
The specific embodiment
As shown in Figure 1, filter comprises housing 1, screen casing 2, connecting plate 3 and loam cake 4.Housing 1 is tubular, is provided with conical sand deposition hopper 5 in housing 1 bottom and is used for the feet 6 of support housing 1, and feet 6 is vertically stood whole housing 1, thereby sand deposition hopper 5 is provided with a sand export 7 also on vertical plane in the bottom of sand deposition hopper 5.Housing 1 outside is provided with water inlet 8, and housing 1 inside is provided with baffle plate 9 in the position of corresponding water inlet 8.Loam cake 4 is the dome shape, and top is provided with delivery port 11 and backwash mouth 12, and delivery port 11 is positioned at the centre position at loam cake 4 tops, and backwash mouth 12 is near delivery port 11.Connecting plate 3 in loam cake 4 inside, forms a chamber with loam cake 4 inside by welded and installed.Screen casing 2 is a hollow structure inside, and as shown in Figure 2, its top is provided with the tubulose guide pin bushing 13 that is used to connect, and is provided with through hole in the middle of the guide pin bushing 13, and the outside is provided with screw thread, and therefore screen casing 2 hollows have only by guide pin bushing 13 is unimpeded the connection with the external world.Screen casing 2 tops are installed on the connecting plate 3 by guide pin bushing 13, be threaded between guide pin bushing 13 and the connecting plate 3, and also be provided with sealing ring 14 between guide pin bushing 13 and connecting plate 3.The inner chamber of screen casing 2 is communicated with the chamber of loam cake 4 by guide pin bushing 13.Loam cake 4 bottom radius are identical with housing 1 radius, and loam cake 4 links together by clip 15 after being installed on the housing 1.
As shown in Figure 3, the work system of this filter has comprised product water tank 16, magnetic valve 17, intake pump 18, backwashing pump 10, filter 19.Producing water tank 16 links to each other with the delivery port 11 of filter 19 by pipeline; Intake pump 18 links to each other with the water inlet 8 of filter 19 by pipeline; Backwashing pump 10 links to each other with the backwash mouth 12 of filter 19 by pipeline; Sand export 7 at filter 19 goes out to connect magnetic valve 17.During work, magnetic valve 17 cuts out, send out and to wash pump and close, intake pump 18 draws water in the input filter 19, and strong current slows down under the effect of baffle plate 9 and enters filter 19 inside, water gathering sand deposition hopper 5 in earlier, enter screen casing 2 after waiting to rise, be blocked in screen casing 2 outsides by screen casing 2 screen rear impurities, comparatively Qing Jie current advance loam cake 4 and enter in the product water tank 16 by pipeline, do further filtration treatment after the collection.The impurity that is got off by sieving is deposited in the sand deposition hopper 5, so a period of time rear electromagnetic valve 17 opens, and intake pump 18 stops into water, and the impurity of deposition is outflow filter 19 under the self gravitation effect.When screen casing 2 needs backwash, magnetic valve 17 is opened, and backwashing pump 10 draws water in the input filter 19, will wash away attached to the impurity on the screen casing 2 totally, so, dash the impurity that falls again through sand export 7 outflow filters 19 because be that time of screen casing 2 structure backwashes is shorter.Because the utility model volume is little, in light weight, thus convenient in carrying, and also backwashing time is short, thus improved drainage rate.
