Description

A kind of automatic back-flushing filtering device
Technical field
The utility model belongs to water treatment facilities, is specifically related to a kind of automatic back-flushing filtering device.
Background technology
Development along with modern industry, new type auto backwash filter uses very extensive, especially existing automatic backwash type filter, efficiently, but this type of fine filter is affected by seawater quality larger because filtering accuracy is had relatively high expectations, at silts such as the Yangtze river basins than multizone, common backwash filter very easily stops up, and can't normally use, and affects boats and ships and normally navigates by water.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of automatic back-flushing filtering device to be provided.
technical scheme: a kind of automatic back-flushing filtering device, comprise housing, automatic back-flushing filtering device, cover plate and motor, described housing comprises upper shell and lower house, described cover plate is riveted on upper shell, described motor is installed on the cover board, described automatic back-flushing filtering device is sleeved in housing, comprise outlet conduit, inlet channel, drain passage, blow-off line, ultrasonic transducer, the backwash arm, filter core and filter core water conservancy diversion box, described outlet conduit and inlet channel are sleeved on the housing homonymy, described ultrasonic transducer is riveted on the housing surrounding, bottom at lower house is provided with drain passage, described filter core is socketed on the backwash arm, filter core water conservancy diversion box is installed in the junction of backwash arm and filter core, described blow-off line is connected with the backwash arm.
As preferably, described housing is Stainless Steel Shell or carbon steel shell, and rubber liner is arranged in housing.
As preferably, the inside of described filter core is the double-layer leaching net group, and outer filter is followed successively by the outer protecting wire nets of 32 orders, and 40 microns precision screen packs and outer lining, inner filter screen are followed successively by 200 microns coarse filtration nets and internal layer lining.
As preferably, the radical of described filter core is the 2-20 root.
As preferably, described ultrasonic transducer is oscillator pattern transducer or rod-type ultrasonic transducer.
As preferably, described filter core water conservancy diversion box is that reducing is connected with blow-off line.
Beneficial effect: a kind of automatic back-flushing filtering device described in the utility model, have simple in structure, easy to operate characteristics, the Double-level Reticulated group is filtered when filtering, large small impurities layered filtration, significantly improve filter effect, not only the dirt of filter core inner chamber is rinsed when backwash, and the dirt of double-layer leaching net interlayer also can rinse in the lump, be equivalent to the internal layer outer filter and separately clean, improve cleaning performance; In addition, hyperacoustic vibration makes wire side impurity to adhere to, and has guaranteed cleaning performance, simultaneously can carry out deactivation to biology again, reduces biological self reproducing and corrosion, extension device service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of filter core in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment is described in detail.
as Fig. 1, shown in 2, a kind of automatic back-flushing filtering device, comprise housing, automatic back-flushing filtering device, cover plate 3 and motor 9, housing comprises upper shell 1 and lower house 2, cover plate 3 is riveted on upper shell 1, motor 9 is arranged on cover plate 3, automatic back-flushing filtering device is sleeved in housing, comprise outlet conduit 4, inlet channel 5, drain passage 6, blow-off line 7, ultrasonic transducer 8, backwash arm 10, filter core 11 and filter core water conservancy diversion box 12, outlet conduit 4 and inlet channel 5 are sleeved on the housing homonymy, ultrasonic transducer 8 is riveted on the housing opposite side, be provided with drain passage 6 in the bottom of lower house 2, filter core 11 is socketed on backwash arm 10, junction at backwash arm 10 and filter core 11 is equipped with filter core water conservancy diversion box 12, blow-off line 7 is connected with backwash arm 10, housing is Stainless Steel Shell, the inside of filter core 11 is double-layer leaching net, upper screen is followed successively by the outer protecting wire net 13 of 32 orders, 40 microns precision screen packs 14 and outer lining 15, lower screen is followed successively by 200 microns coarse filtration nets 16 and internal layer lining 17, the radical of filter core 11 is the 2-12 root.
When automatic back-flushing filtering device is worked, fluid enters in lower house 2 from inlet channel 5, flow into from outside to inside filter core 11, successively by internal layer lining 17,200 microns coarse filtration nets 16, pass successively the more filtered water body of the outer protecting wire net 13 of 15,40 microns precision screen packs of outer lining, 14,32 orders directly from outlet conduit 4 outflows after entering double-layer interlayer; When pressure reduction arrives preset value or arrives preset value running time, filter operation automatic backwash process, filtered water body from outside to inside pass through the 32 outer protecting wire nets 13 of orders, 40 microns precision screen packs 14, outer linings 15 arrive the filter core interlayers, again by 200 microns coarse filtration nets 16, and internal layer lining 17,, by the dirt in filter core water conservancy diversion box 12 collection filter cores 11 inside and filter screen interlayer, enter backwash arm 10, by blow-off line 7 discharge strainers.
