Description
Technical field
The utility model relates to a kind of filter, particularly a kind of automatic back-flushing filtering device.
Background technology
The Industrial Boiler water is by removing Ca, the Mg ion in anhydrating after the exchanger in the Na-ion exchanger (resin) exchange, being referred to as demineralized water at present.After exchanger lost efficacy, promptly it is replaced reducing/regenerating, recovers exchange capacity, and have suspensions such as a large amount of silt, fiber in the Nacl, promptly stick to exchanger (resin) surface in the interchanger if enter with the NaCl salt solution, cause resin stain, reduce exchange capacity.Usually solve this problem by before pump, adding filter, but existing filter exists following problem: 1, the filter area of filter core is little, and filter efficiency is low, and the sieve diameter of filter core is 2-4mm, can not remove fine suspension in the water, and these suspensions are also easily with sieve pore blockade; 2, the quartz sand filtration is not meticulous, and equipment volume is big, and the cleaning amount is big; When 3, filter screen is blocked, cost is increased, clean, increased workload again and pull down filter screen by shutdown by changing filter screen.
The utility model content
At above-mentioned technical problem, the purpose of this utility model provides a kind of automatic back-flushing filtering device that can remove stop up the sieve aperture suspension, and the utility model is novel to have advantage easy to use.
The technical scheme that realizes the purpose of this utility model is as follows: filter core is unsettled to be arranged in the housing, one end of filter core is connected with water knockout drum, the other end of filter core is connected with drainpipe, one end of one blow-off pipe passes housing and is connected with water knockout drum, described housing appearance is provided with and is communicated with the dirty pipe of letting out of this housing inner chamber, be provided with flow sensor in the described drainpipe, this flow sensor is electrically connected with a controller, be equipped with magnetic valve on described blow-off pipe and the drainpipe, each magnetic valve is electrically connected with described controller, also be provided with the cleaning hose that is communicated with this drainpipe on the drainpipe, the water inlet port of cleaning hose is connected with controller, described cleaning hose is positioned at the upstream extremity of drainpipe, and the magnetic valve on the described drainpipe is positioned at the downstream of this drainpipe.
Described water knockout drum comprises shell and is arranged at the interior activated carbon of shell, some apopores evenly are set on the described shell.
Adopted such scheme, described housing appearance is provided with and is communicated with the dirty pipe of letting out of this housing inner chamber, and the sewage after the backwash can be let out dirty pipe by this and discharge.Be provided with flow sensor in the drainpipe, this flow sensor is a velocity flowmeter.This flow sensor is electrically connected with a controller, be equipped with magnetic valve on described blow-off pipe and the drainpipe, each magnetic valve is electrically connected with described controller, also be provided with the cleaning hose that is communicated with this drainpipe on the drainpipe, the water inlet port of cleaning hose is connected with controller, flow velocity by water in the flow sensor detection drainpipe transfers back to controller with detection signal, by controller control closed electromagnetic valve and unlatching.Therefore, when suspension stops up the sieve aperture of filter core, water velocity in the drainpipe slows down, controller cuts out the magnetic valve of blow-off pipe and drainpipe, and the valve open of control cleaning hose, clear water is entered in the filter core by drainpipe, filter core is carried out back flush, the suspension that is attached on the filter core is poured in the cavity of housing, discharge housing by letting out dirty pipe.Reach like this and need not dismounting and can clean filter core, not only easy to use, and time saving and energy saving, have the high advantage of cleaning efficiency.
Described water knockout drum comprises shell and is arranged at the interior activated carbon of shell, some apopores evenly are set on the described shell.By the activated carbon in the water knockout drum, can the sewage of discharging from blow-off pipe be filtered first, with bulky suspension filtering,, reduce wash number to filter core to alleviate the work load of filter core.
Description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model;
In the accompanying drawing, 1 is housing, and 2 is filter core, and 3 is water knockout drum, and 4 is drainpipe, and 5 is magnetic valve, and 6 is cleaning hose, and 7 is blow-off pipe, and 8 is magnetic valve, and 9 for letting out dirty pipe, and 10 is controller, and 11 is flow sensor.
