Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of device with a plurality of filter membranes.
Background technology
Show present device on the market like Fig. 1 with two filter membranes; Comprise the first filter membrane S1, the second filter membrane S2, inlet tube S3, outlet S4; Said inlet tube S3 all is communicated with the two ends import of the first filter membrane S1, the second filter membrane S2, and said outlet S4 all is communicated with the centre exit of the first filter membrane S1, the second filter membrane S2.In like manner, the device with two above filter membranes then is that the two ends import of a plurality of filter membranes all is communicated with inlet tube S3 with a plurality of filter membrane parallel connections, and the centre exit of a plurality of filter membranes all is communicated with outlet S4.When this device is cleaned, often adopt the backwash method, promptly,, thereby the dirt in the filter membrane is got rid of from inlet tube S3 water outlet from outlet S4 water inlet.This device has following shortcoming:
One, because the import of each filter membrane and outlet are communicated with respectively and can't block, therefore can only shut down all filter membranes are carried out backwash, can not carry out backwash separately and keep other filter membranes normally to move certain or certain several filter membranes;
Inlet tube S3 water inlet when two, normally moving, outlet S4 water outlet, the input channel of water is switched in outlet S4 water inlet, inlet tube S3 water outlet during backwash repeatedly, and is cumbersome.
The utility model content
The purpose of the utility model is to provide a kind of multimembrane filter of setting up blow-off pipe and magnetic valve, to solve inlet tube and the cumbersome problem of outlet that can not under running status, carry out backwash and switch water repeatedly the part filter membrane that exists in the background technology.
To achieve these goals, the technical scheme of the utility model multimembrane filter is: a kind of multimembrane filter comprises two filter membranes side by side; The top of this filter membrane is provided with import, and the middle part of this filter membrane is provided with outlet, and the bottom of this filter membrane is provided with sewage draining exit; Also comprise inlet tube, outlet and blow-off pipe, the import of each filter membrane all is communicated with inlet tube, and the outlet of two filter membranes is communicated with through arm; Said arm is communicated with outlet through being responsible for; The sewage draining exit of each filter membrane all is communicated with blow-off pipe, and the import department of each filter membrane and sewage draining exit place are equipped with control valve, on the said person in charge, are provided with control valve.The mentality of designing of this multimembrane filter is: should guarantee not switch water inlet pipe again can be to the filter membrane backwash; Then adopt the method for two mutual backwashes of filter membrane; The normal water inlet and the water outlet that promptly keep a filter membrane get into the delivery port of another filter membrane through pipeline and valve with the water outlet guiding of this filter membrane, and discharge from the sewage draining exit of another filter membrane; In like manner, can realize not switching under the situation of inlet tube two filter membranes are carried out backwash.This independent principal claim is the situation design to two filter membranes.
A kind of multimembrane filter comprises at least three filter membranes side by side, and the top of this filter membrane is provided with import; The middle part of this filter membrane is provided with outlet, and the bottom of this filter membrane is provided with sewage draining exit, also comprises inlet tube, outlet and blow-off pipe; The import of each filter membrane all is communicated with inlet tube; The outlet of all filter membranes is communicated with through arm, and this section arm between the outlet of adjacent filter membrane all is communicated with outlet through being responsible for, and the sewage draining exit of each filter membrane all is communicated with blow-off pipe; The import department of each filter membrane and sewage draining exit place are equipped with control valve; Each is equipped with control valve on being responsible for, and on this section arm between the adjacent filter membrane outlet, is equipped with control valve, and the tie point of the outermost person in charge and arm is between outermost filter membrane outlet of homonymy and control valve.The mentality of designing of this multimembrane filter is: should guarantee not switch water inlet pipe again can be to the filter membrane backwash; Then adopt the method for two adjacent mutual backwashes of filter membrane; The normal water inlet and the water outlet that promptly keep the outside one filter membrane get into the delivery port of the 3rd filter membrane through pipeline and valve with the water outlet guiding of another filter membrane, and discharge from its sewage draining exit; And blocking-up and being communicated with of other filter membranes rationally be set through valve; In like manner, can realize not switching under the situation of inlet tube two filter membranes are carried out backwash, and guarantee that other filter membranes are in normal operating conditions.
As preferably, said control valve is a magnetic valve.All adopt magnetic valve, can realize that the break-make of working procedure and backwash is controlled automatically.
The beneficial effect of the utility model multimembrane filter is: this multimembrane filter is realized the effect of adjacent two filter membrane backwashes keeping the inlet tube water inlet constant and do not influence under the situation of other filter membrane operate as normal.
