Abstract
The utility model discloses an automatic back-flushing differential filter with simple structure, convenience in operation and high working efficiency. The automatic back-flushing differential filter comprises a water inlet, filtering tanks, an observation window, an exhaust opening and a water outlet. The filter is characterized by consisting of the plurality of filtering tanks in parallel; water inlet valves are arranged on the connection parts of the water inlet and the filtering tanks; water outlet valves are arranged on the connection parts of the filtering tanks and the water outlet; the exhaust opening is connected with the filtering tanks; back-flushing water outlets are arranged at the tops of the filtering tanks; a manhole, a compressed air opening and a discharging opening are arranged on one side of a tank body of each filtering tank from top to bottom.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of quartz sand filtration that is applicable to, the filter in the fields such as charcoal absorption, biological carbon filtration.
Background technology
At present, filter generally adopts the large discharge capacity of single barrel of filtering tank to filter, and needs to rinse operation in filter process, just must stop filtration work, inefficiency like this, and water resource waste is serious.
Summary of the invention
The utility model provides a kind of simple in structure, easy to operate in order to address the above problem, the automatic backwash differential expression filter that operating efficiency is high.
The technical scheme that the utility model adopts is: a kind of automatic backwash differential expression filter, comprise water inlet, filtering tank, observation window, exhaust outlet, delivery port, it is characterized in that: described filter consists of side by side a plurality of filtering tanks, described water inlet and filtering tank junction are provided with water intaking valve, described filtering tank and delivery port junction are provided with outlet valve, described exhaust outlet is connected with filtering tank, described filtering tank top is provided with backwash delivery port, described filtering tank can body one side is provided with manhole from the top down, compressed air mouth, discharging opening.
Useful effect of the present utility model is: can be by the gauge tap of water intaking valve and outlet valve, the backwash work that divides tank, can not only continually carry out sewage disposal work, can utilize sewage to carry out the backwash work of filtering tank simultaneously, not only improve operating efficiency, improved the utilization rate of water resource simultaneously.
Accompanying drawing explanation
Fig. 1 is front view signal of the present utility model;
Fig. 2 is left view signal of the present utility model;
Fig. 3 is top view signal of the present utility model;
In figure: 1, water inlet; 2, filtering tank; 3, delivery port; 4, observation window; 5, exhaust outlet; 11, water intaking valve; 12, backwash delivery port; 21, manhole; 22, compressed air mouth; 23, discharging opening; 31, outlet valve.
The specific embodiment
As Fig. 1, a kind of automatic backwash differential expression filter shown in Fig. 2 and Fig. 3, comprise water inlet (1), filtering tank (2), observation window (4), exhaust outlet (5), delivery port (3), it is characterized in that: described filter consists of side by side a plurality of filtering tanks (2), described water inlet (1) is provided with water intaking valve (11) with filtering tank (2) junction, top, described filtering tank (2) bottom is provided with outlet valve (31) with delivery port (3) junction, described exhaust outlet (5) is connected with filtering tank (2), described filtering tank (2) top is provided with backwash delivery port (12), described filtering tank (2) can body one side is provided with manhole (21) from the top down, compressed air mouth (22), discharging opening (23).
Principle of the present utility model is: during normal filtration, sewage is entered after filtering tank (2) filters and got rid of by delivery port (3) by water inlet (1), and now all water intaking valves (11) and outlet valve (31) are in open mode.During backwash, filter filtering tank arranged side by side carries out backwash successively, and now water intaking valve (11) is closed, and utilizes water purification after all the other filtering tanks filter to rinse filtering tank now.
