Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a filter tube, including straining a section of thick bamboo 1, it is provided with filter core 2 in 1 to strain, be provided with filter tube 3 in the filter core 2, the bottom of straining a section of thick bamboo 1 is provided with drain 4 and water inlet 5, it is provided with delivery port 6 to strain 1 top, be provided with a plurality of through-holes 7 on the filter tube 3, the bottom of filter tube 3 is connected with the end cap, 2 covers of filter core are established on the end cap and with be provided with filter media gasket 9 between the end cap, 2 and strain between the section of thick bamboo 1 and the filter core, water inlet 5 and drain 4 and cavity 10 intercommunication, delivery port 6 and the inside intercommunication of filter tube 3 and with keep apart through filter media gasket 13 between the cavity 10, be provided with filter core seat 12 between 2 of filter core.

The operating principle of a filter tube 3 of this scheme is, liquid gets into filter tube 3 from water inlet 5, through cavity 10, filter core 2 to filter tube 3 inside, discharge from delivery port 6 at last, this is the filtration process of filter tube 3, during the blowdown, aerify in the filter tube 3 from delivery port 6, because delivery port 6 and cavity 10 keep apart, the inside pressurization of gas admission filter tube 3, under the pressure effect, liquid is to following filter tube 3 in to the backwash of filter core 2 surface, make the filth on filter core 2 surface along with liquid discharge from cavity 10 and drain 4, realize the backwash process, of course, when specifically using, every inlet outlet 6 can all receive specific switch solenoid valve control.
