General backwash medium filter comprises tank body, water inlet pipe, outlet pipe, blow-off pipe, tank body is separated into two-part dividing plate, be installed in the filter cap on the dividing plate, tank body is provided with filter medium loading port and outlet, filter medium is from the filter medium loading port tank interior of packing into, and be distributed to above the dividing plate in the tank body, the dividing plate top communicates with water inlet pipe and blow-off pipe, the below communicates with outlet pipe, after current enter from water inlet, through after the filter media, clean water flows out from outlet pipe, when carrying out backwash, close water inlet pipe, current enter from outlet pipe, and from the lower partition backwash filter medium, the impurity in the filter medium is flushed to drain tank external body behind the blow-off pipe by water; Water inlet pipe, outlet pipe that centrifugal filter comprises tank body, communicates respectively with tank body, blow-off pipe, the current in the water inlet pipe enter tank body along the tangential direction of tank body, and form swirling flow in tank interior, through the effect of swirling flow, contamination precipitation is discharged from blow-off pipe to tank base.Known combination filter is that sandrock filter externally is connected with pipeline successively with centrifugal filter, and shortcoming is: medium filter and centrifugal filter apart arrangement, and floor space is big; Pipeline connects many, waste material, and damage by water is big, the cost height; The work system of medium, centrifugal filter is relatively independent, during system works, operate complicated operation, loaded down with trivial details respectively.
Summary of the invention
The utility model purpose is to provide a kind of compact conformation, floor space little, the combination filter that cost is low, easy to operate.
The technical scheme of the utility model technical solution problem is: a kind of combination filter, comprise: medium filter tank body, centrifugal filter tank body, water inlet pipe, outlet pipe, blow-off pipe, the medium filter tank interior is provided with a medium filter tank body dividing plate divided into two parts, dividing plate is provided with the hole, the hole is provided with the filter cap, the dividing plate below communicates with outlet pipe, and centrifugal filter tank body upper end communicates with described water inlet pipe, and the lower end is fixed on the dividing plate and with described blow-off pipe and communicates;
Above-mentioned backwash combination filter, as further improvement, described dividing plate below is provided with baffle plate, form the cavity that communicates with described outlet pipe between dividing plate and the baffle plate, form deposit cavity between baffle plate below and the described medium filter tank body, deposit cavity communicates with described centrifugal filter and blow-off pipe, enters behind the deposit cavity again by blow-off pipe discharge tank body from the impurity of centrifugal filter discharge, can make the impurity discharging so smoothly, reduce the probability that blow-off pipe stops up;
Above-mentioned backwash combination filter, described centrifugal filter tank body upper end is provided with the overflow pipe that is communicated with centrifugal filter tank body and medium filter tank body, the overflow pipe outer wall is provided with the taper ring plate, can increase the current rotation dynamics in the centrifugal tank body like this, impurity is deposited rapidly, strengthen filter effect;
Above-mentioned backwash combination filter, described centrifugal filter tank body top is provided with the cross outlet pipe, the current that come out from the centrifugal filter tank body are evenly disperseed, reduced the impact of current to the filter medium in the medium filter tank body, thereby filter medium is uniformly dispersed, makes good filtration effect;
Above-mentioned backwash combination filter, as further improvement, described centrifugal filter tank body top is provided with the arc outlet pipe, the current that come out from the centrifugal filter tank body are evenly disperseed, reduced the impact of current to the filter medium in the medium tank body, thereby filter medium is uniformly dispersed, makes good filtration effect.
The beneficial effects of the utility model: centrifugal filter tank body and medium filter tank body are integrated, transportation, installation, easy to operate; The centrifugal filter tank body is located at the medium filter tank interior, compact conformation, and floor space is few; Connecting line is few, saves material, and cost is low.
