For in the Chinese utility model patent specification of CN2803494Y a kind of inversion type filtering oily sewage device is disclosed at Granted publication number, it comprises tank body, be provided with baffle plate in the tank body, baffle plate is separated into the water chamber on top and the filter chamber of bottom with tank inner chamber, baffle plate is provided with installing hole, inverted suspension is equipped with the filter core that delivery port is positioned at the top in the installing hole of baffle plate, and the delivery port of filter core is communicated with water chamber, and because the delivery port of filter core is positioned at the top, so think filter core " inversion ".Offer water inlet and the sewage draining exit that is communicated with filter chamber in tank base, be provided with oil exit pipe in corresponding position, filter chamber top on the tank body, the tank body top is provided with the delivery port that is communicated with water storage cavity.
Filter core in the above-mentioned filter is inverted, under the gravity effect, the partial impurities that attaches on filter core can fall, but still some impurity attaches on filter core, this part impurity can influence filter core to the normal filtration of sewage, and then shortens filter core service life, uses after a period of time, the more renew cartridge of having to, otherwise can't guarantee the filter efficiency of filter.
The utility model content
The purpose of this utility model is to provide a kind of inversion type filtering oily sewage device, reduces the filter core technical problem in service life to solve in the prior art when impurity attaches after on the filter core.
For achieving the above object, the technical scheme of inversion type filtering oily sewage device provided by the utility model is: inversion type filtering oily sewage device, comprise tank body, be provided with the baffle plate that inner chamber with tank body is separated into the filter chamber of the water chamber on top and bottom in the tank body, be hung with filter core on the baffle plate, the top of filter core is provided with the delivery port that is communicated with described water chamber, tank body is provided with the outlet pipe that is communicated with water chamber, described tank body is provided with being used for to the backwash water pipe of water chamber input backwash water of being communicated with described water chamber, the backwash water pipe is provided with switch valve, be communicated with backwashing pump on the backwash water pipe, described tank base is provided with the discharge tube that is used for draining backwash water and impurity that is communicated with described filter chamber.
Also be provided with the blast pipe that is communicated with described water chamber on the described tank body, blast pipe is provided with magnetic valve.
Be serially connected with threeway on the described outlet pipe, the backwash water pipe is communicated with threeway, and the backwash water pipe is communicated with described water chamber by threeway, outlet pipe.
Described discharge tube comprises for the drainpipe of draining with for the blow-off pipe of discharging impurity.
Described drainpipe is communicated with the backwash water collection box.
Described discharge tube is for being used for the blow-off pipe of draining and discharge impurity.
The beneficial effects of the utility model are: the tank body of inversion type filtering oily sewage device provided by the utility model is provided with the backwash water pipe, when impurity attaches on filter core and influences the filter effect of filter core, open the switch valve on the backwash water pipe, in water chamber, inject backwash water by backwashing pump and backwash water pipe, backwash water enters in the filter core and from the filter core outer peripheral face through the delivery port of filter core and discharges, realization is to the reverse cleaning of filter core, and the backwash water that carries impurity is drained through discharge tube.Filter provided by the utility model charges into backwash water by the backwash water pipe in use on filter core, filter core is oppositely cleaned, and can guarantee the filter effect of filter like this, prolongs the service life of filter core, reduces cost of water treatment.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of inversion type filtering oily sewage device provided by the utility model.
The specific embodiment
As shown in Figure 1, a kind of embodiment of inversion type filtering oily sewage device, filter among this embodiment comprises tank body 1, be provided with the baffle plate 13 that inner chamber with tank body is separated into the filter chamber 12 of the water chamber 11 on top and bottom in the tank body 1, be hung with filter core 14 on the baffle plate 13, the top of filter core 14 is provided with the delivery port that is communicated with described water chamber 11, the top of tank body 1 is provided with the outlet pipe 2 that is communicated with water chamber, outlet pipe is provided with switch valve 21, the middle part of tank body 1 is provided with collection tube 4, the bottom of tank body 1 is provided with the water inlet pipe 7 that is communicated with filter chamber, water inlet pipe 7 is provided with switch valve, unlike the prior art be: also be provided with being used for to the backwash water pipe 3 of water chamber input backwash water of being communicated with described water chamber on the described tank body 1, backwash water pipe 3 is provided with switch valve 31, is communicated with backwashing pump 5 on the backwash water pipe 3.Be serially connected with threeway at outlet pipe 2, back suction water pipe 3 is communicated with threeway, and backwash water pipe 3 is communicated with described water chamber 11 by threeway, outlet pipe 2.Be provided with the discharge tube that is used for discharging backwash water and impurity that is communicated with described filter chamber in the bottom of tank body 1, discharge tube is blow-off pipe 6, and blow-off pipe is provided with switch valve 61, and blow-off pipe herein plays the effect of discharging backwash water simultaneously.Also be provided with the blast pipe that is communicated with described water chamber on the described tank body 1, the vollyball pipe is provided with magnetic valve.
