Description
Technical field
The utility model relates to a kind of filter, particularly a kind of anti-cleaning and filtrating equipment.
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 residues 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 tiny residue in the water, and these residues 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 energy and removes the anti-cleaning and filtrating equipment that adheres to the residue on the filter core, the utlity model has advantage easy to use.
The technical scheme that realizes the purpose of this utility model is as follows: anti-cleaning and filtrating equipment, housing outer surface is provided with and is communicated with the dirty pipe of letting out of this housing inner chamber, the housing inner chamber is provided with filter core and water knockout drum connects, housing one end is provided with the blow-off pipe that is communicated with water knockout drum, the housing other end is provided with drainpipe, described filter core is some long fibre silks, one end of each long fibre silk is fixed on the internal face of housing, the other end is connected with the connecting plate that can do upper and lower displacement, this connecting plate is connected with a wire rod thread, the screw mandrel drive motors outer with being positioned at housing is connected, described housing be provided with restriction connecting plate stroke on, lower stroke switch, described drainpipe is provided with cleaning hose, is equipped with control valve on described blow-off pipe and the 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.Described filter core is some long fibre silks, and the long fibre silk can filter the liquid of blow-off pipe output.One end of each long fibre silk is fixed on the internal face of housing, the other end is connected with the connecting plate that can do upper and lower displacement, this connecting plate is connected with a wire rod thread, the screw mandrel drive motors outer with being positioned at housing is connected, in the time of too much need cleaning along with the filter residue that adheres on the filter core, close the control valve of drainpipe and blow-off pipe, clear water is entered in the housing and can wash the long fibre silk by cleaning hose.In flushing process, open drive motors and just changeing the rotation of drive screw mandrel, the connecting plate that is threadedly connected on the screw mandrel is moved downward, the long fibre silk is compressed, the outstanding washing of long fibre silk is removed in help, when connecting plate is run into lower stroke switch, drive electronic controlled instruction counter-rotating, drive connecting plate by screw mandrel and move upward.Such cleaning need not dismounting and can clean filter core, and is not only easy to use, and time saving and energy saving, has 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 residue 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 control valve, and 6 is cleaning hose, and 7 is blow-off pipe, and 8 is control valve, and 9 for letting out dirty pipe, and 10 is connecting plate, and 11 is screw mandrel, and 12 is drive motors, and 13 is upper stroke switch, 14 lower stroke switch.
The specific embodiment
With reference to Fig. 1, anti-cleaning and filtrating equipment of the present utility model, housing 1 outer surface are provided with and are communicated with the dirty pipe 9 of letting out of this housing inner chamber, and housing one end is provided with the blow-off pipe 7 that is communicated with water knockout drum, and the housing other end is provided with drainpipe 4.Be respectively equipped with by- pass valve control 5,8 on blow-off pipe 7 and the drainpipe 4, described drainpipe is provided with cleaning hose 6, and cleaning hose 6 is positioned at the upstream extremity of drainpipe, and the control valve 5 on the drainpipe is positioned at the downstream of this drainpipe.Housing 1 inner chamber is provided with filter core 2 and water knockout drum 3 connects, and described filter core 2 is some long fibre silks, and the length of long fibre silk is less than or equal to housing inner chamber height.One end of each long fibre silk is fixed on the internal face of housing, and the connecting plate 10 that the other end and can be done upper and lower displacement is connected, and this connecting plate is threaded with a screw mandrel 11, and connecting plate and screw mandrel constitute a screw mechanism.The screw mandrel drive motors 12 outer with being positioned at housing is connected, and described housing 1 is provided with the upper and lower stroke switch 13,14 of restriction connecting plate stroke.Water knockout drum 3 can disperse the liquid of blow-off pipe output, makes liquid uniform, and carries out primary filter.Water knockout drum 3 comprises shell and is arranged at the interior activated carbon of shell that some apopores evenly are set on the described shell, and the aperture of apopore is 10mm.
