The utility model has two working modes, a normal filtering mode and a back washing mode. Outside these two kinds of mode, the utility model discloses of course can also not add the diatomaceous earth granule, directly use filter rod 5 to filter impurity, this is the utility model discloses a degradation user mode is applicable to the relatively better occasion of quality of water, and this kind of user mode is also simpler, does not describe in detail.
In the normal filtration mode, the emptying valve 25, the backflushing water supply valve 19 and the backflushing blowdown valve 21 are closed, the valve 8 for coating is opened, water containing a proper amount of diatomite particles is added into the water inlet cavity 4, and then the valve 8 for coating is closed; opening the water inlet valve 27, the water inlet main valve 22, the water outlet main valve 18 and the water outlet valve 17, enabling water to be filtered to enter the water inlet cavity 4 along the water inlet main pipe 11, the first tee joint 12, the water inlet pipe 13 and the horn-shaped water through port 23, carrying diatomite to flow to the filter stick 5, entering the filter stick 5 along the radial direction of the filter stick 5 through the filter layer, then entering the water outlet cavity 3 from the water outlet at the top end of the filter stick 5, and then flowing to the downstream along the water outlet pipe 6, the second tee joint 15 and the water outlet main valve 18; in the process, the diatomite particles are gathered and attached to the outer surface of the filter stick 5 (filter layer) under the action of water pressure to form a diatomite membrane, and the diatomite membrane has higher filtering precision compared with the filter stick 5, so that the filtering effect is improved. If the diatomite membrane is not available, the filtered particles can be continuously embedded into the filter layer of the filter stick 5, and the particles embedded into the filter layer of the filter stick 5 can not be completely removed by backwashing. After the diatomite membrane is formed, the particles are blocked by the diatomite membrane, and the particles cannot be embedded into the surface of the filter layer of the filter stick 5; the diatomite membrane is very easy to fall off from the filter stick 5 during back washing, so the utility model can rapidly and thoroughly recover the filtering capacity during back washing.
In the back flushing mode, the valve 8 for film coating, the emptying valve 25, the main water outlet valve 18 and the water inlet valve 27 are all closed, the main water inlet valve 22, the water outlet valve 17, the back flushing water supply valve 19 and the back flushing blow-down valve 21 are opened, water in the main water inlet pipe 11 enters the water outlet cavity 3 along the back flushing communicating pipe 14, the second tee 15 and the water outlet pipe 6, then enters the filter stick 5 in a reverse direction from the water outlet at the top end of the filter stick 5 downwards, then enters the water inlet cavity 4 through the filter layer of the filter stick 5 in a radial direction, and washes away the attached diatomite film when the water passes through the filter layer, and carries the washed away diatomite particles and the particles intercepted by the original diatomite to enter the back flushing blow-down pipe 20 through the horn-shaped water inlet 23 and finally to be discharged.
When the filter stick 5 is installed or replaced, the maintenance top cover 10 is opened, the original filter stick 5 can be pulled out upwards, and a new filter stick 5 is inserted into the corresponding hole position of the pore plate 2. When the whole machine is overhauled, the emptying valve 25 is opened, and maintenance is carried out after emptying.
Although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that: the present invention may be modified or substituted with equivalents without departing from the spirit and scope of the invention, which should be construed as being limited only by the claims.
