The sand medium is set on the medium supporting board inside the casing, the filtering screen net is set below the medium supporting board of the casing, the liquid inlet and the sand back flushing outlet are set in the top of the casing; and the screen net back flushing outlet and the liquid outlet are set in the lower part of the casing. The present invention has the advantages of small covered area, low investment, easy control and high liquid filtering precision.
Description
Affiliated technical field
The invention belongs to the equipment of filter liquide, a kind of integrated net filter of specific design.
Background technology
The sandrock filter and the granular membrane of home and abroad employing at present are split type.In use to institute's filtered liquid required precision not too high can use the sandstone filter separately; Can use granular membrane separately under the situation preferably in the liquid condition; But, form split type combination filter station and use in that the local many of liquid required precision height and liquid situation complexity are connected sandstone and granular membrane.
Though be the filtering accuracy that can improve liquid, also there is certain problem in split type combination filter station:
1, increased the use place of equipment, thus the also corresponding construction investment that increases storage equipment.
2, the be in operation backwash process of each filter carries out respectively, that is: sandstone medium filter, granular membrane carry out backwash separately respectively, thereby have increased the personnel's amount of labour in the running.
If 3 split type filter stations adopt automatic backwash, the control of each filter also must be carried out separately, therefore increased the usage quantity of motor-operated control valve, controller, thereby has correspondingly increased the difficulty that equipment is realized automation.
4, because these two kinds of filters are split type uses, and its by-pass valve control, controller also are necessary separately, therefore the reduction of filter station manufacturing cost is restricted.
Summary of the invention
The purpose of this invention is to provide a kind of floor space little, reduce investment outlay, control, integrated net filter that the liquid filtering precision is high easily.
This integrated net filter, comprise sandstone medium inlet 1, liquid-inlet 2, sandstone backwash outlet 3, sandstone medium 4, shell 5, medium holder orifice plate 6, filter screen 7,10,11, liquid outlet 8, its sandstone medium 4 is arranged in the shell 5 and places on the medium holder orifice plate 6, filter screen 7,10,11 are arranged in the shell 5 of medium holder orifice plate 6 belows, make sandstone medium 4 and filter screen 7,10,11 in same shell 5, liquid-inlet 2, sandstone backwash outlet 3 is arranged in the top of shell 5, screen cloth backwash outlet 12, liquid outlet 8 is arranged in the bottom of shell 5.
The described filter screen 7 that is arranged in 6 times side spaces of medium holder orifice plate is yi word pattern, at least 1, or be Y-shaped, an end is fixed on the shell 5, and the other end communicates with liquid outlet 8. Filter screen 7,10 is entwined along keel by triangle or wedge-section wire, and the top of triangle or wedge-section wire contacts with keel, and the keel cross section is circular square or oval or wedge shape.Described filter screen 7,10 enters by shell 5, is the plug fit structure in the go side mutually, the other end fixing back sealing with liquid outlet 8.
The described collar plate shape of filter screen 11 for cooperating with shell that is arranged in 6 times side spaces of medium holder orifice plate, filter liquide passes filter screen 11 and enters liquid outlet 8.Screen cloth backwash outlet 12 is arranged in the top of filter screen 11, and liquid outlet 8 is arranged in the below of filter screen 11.This is the plane above collar plate shape filter screen 11, is wedge shape or triangle below, supports by keel 13.
Because thereby the present invention is combined in one with sandstone medium filter, granular membrane to have following good effect:
1, reduced the use place of equipment, thus the also corresponding construction investment that reduces equipment.
2, the be in operation backwash process of equipment is disposable carrying out, that is: backwash is carried out in sandstone medium filter, granular membrane unification, thereby has reduced the personnel's amount of labour in the running.
3, owing to be integral filter,, therefore significantly reduced and realized the motor-operated control valve of control automatically, the usage quantity of controller realizing that the control of filter automatic backwash also is that one is controlled, thus the difficulty of the also big equipment realization automation that lowered the price by a wide margin.
4, because these two kinds of filters are integral types, its valve, controller can be unified control, therefore also make the reduction of filter manufacturing cost become possibility.
5, when the water of backwash when outwards flow out the inside of screen cloth because screen cloth wedge shape or triangular wire towards the ramp effect of keel, strengthen the pressure of backwashing water, reach quick, the clean purpose of flushing.

Specific embodiment
Embodiment 1:
As Fig. 1, integrated net filter shown in 2, sandstone medium 4 is put into shell 5 from sandstone medium inlet 1, and place on the medium holder orifice plate 6, liquid-inlet 2, sandstone backwash outlet 3 is arranged in the top of shell 5, all can above or below screen cloth backwash outlet 12 filter screens that are arranged in 7, the below of the filter screen 7 that present embodiment is arranged in, liquid outlet 8 is arranged in an end of filter screen 7, filter screen 7,10 are entwined along keel by triangle or wedge-section wire, the top of triangle or wedge-section wire contacts with keel, as shown in Figure 8 analyse and observe part, described keel cross section is as shown in Figure 7 round.Filter screen 7 is arranged in the following side space of medium holder orifice plate 6, and according to the needs of fluid purification 1 filter screen 7 of needs at least, present embodiment is 1 yi word pattern filter screen 7, makes sandstone medium 4 and filter screen 7 form upper and lower structure in same housing; This filter screen 7 inserts from the passage of the bottom installing filter screen 7 of shell 5, and an end cooperates with liquid outlet 8 plugs and communicates, and other end sealing and fixing is on shell 5, and whole tank body is fixing by bracing frame 9.
