Description
Technical Field

Background
The V-shaped filter tank is a form of a rapid filter tank, and the name is obtained because the shape of a water inlet tank is V-shaped, and the V-shaped filter tank is also called a granule equalizing filter tank. The V-shaped filter tank adopts a quartz sand filtering layer with uniform particles; a back flushing technology of back flushing gas and water simultaneously and surface sweeping and washing of water to be filtered is adopted; and air cushion distribution air and special long handle filter heads are adopted to carry out air and water distribution process, so that the filter has the advantages of high dirt content of the filter layer, equal water head filtration, good flushing effect and lower filter material loss rate.
The working principle of the V-shaped filter tank is as follows: when filtering, sewage flows through the water inlet valve and the square hole from the water inlet main channel, overflows through the weir mouth, enters the V-shaped groove flooded by sewage through the side hole, enters the filter tank through the water distribution holes and the V-shaped groove weir uniformly at the bottom of the groove, flows into the bottom space through the long handle filter head after being filtered by the homogeneous filter material filter layer, flows into the air water distribution channel from the square hole, and flows into the clean water tank through the water seal well, the water outlet weir and the clean water channel in the pipe gallery.
During flushing, a flushing mode of gas-water combined flushing, namely gas-water back flushing firstly, then gas-water back flushing simultaneously and finally water flushing is adopted. The air flushing opens the air inlet valve, opens the air supply equipment, and air uniformly enters the bottom of the filter tank through the small holes at the upper part of the air-water distribution channel, is sprayed out by the long-handle filter head, scrubs impurities on the surface of the filter material and floats in water, and is flushed into the drainage tank by the surface sweeping water; the air-water back flushing starts the flushing water pump at the same time of air flushing, the flushing water valve is opened, the back flushing water also enters the air-water distributing channel, the air and water respectively flow into the water distributing area at the bottom of the filter tank through small holes and square holes, and uniformly enter the filter tank through the long handle filter head, so that the filter material is further flushed, and the surface scanning is still carried out; stopping air flushing, and continuing to perform surface scanning by independently flushing water, and finally flushing all impurities in the water into the drainage tank.
However, in the back flushing process of the V-shaped filter, as the quartz sand filter layers are closely stacked, the quartz sand filter layers cannot be completely flushed by a flushing mode of air-water combination, so that partial impurities still remain in the quartz sand filter layers, the flushing effect of the quartz sand filter layers can be reduced, the subsequent use effect of the quartz sand filter layers can be influenced, the frequency of the back flushing of the quartz sand filter layers can be increased easily, and the normal use of the V-shaped filter is influenced.

When sewage is filtered, the sewage enters the inner side of the inner membrane 5141 through the fine holes 5144, and the water absorbing layer 5143 absorbs part of the sewage and expands, so that the whole volume of the decontamination particles 514 becomes large.
Preferably, the inner membrane 5141 and the outer membrane 5142 are made of an elastic film material, such as polyvinyl chloride, polyethylene, and the like.
In addition, the outside of the inner membrane 5141 is provided with an adsorption layer 5145, and the adsorption layer 5145 is made of polyacrylamide gel material and is used for adsorbing suspended matters and impurities, so that the effect of filtering sewage can be achieved. Meanwhile, the adsorption layer 5145 can also play a role in protecting the inner film 5141, so that the whole decontamination particle 514 is prevented from being broken when in irregular motion, and the recycling rate of the whole decontamination particle 514 is improved.
Specifically, the inner side of the outer membrane 5142 is provided with a disinfectant 5146, and a capillary 5147 is communicated between the inner membrane 5141 and the outer membrane 5142. As the decontaminating particles 514 expand, the diameter of the capillary 5147 becomes larger, so that the disinfectant 5146 can be slowly released, and the released disinfectant 5146 can remove bacteria, viruses and decomposed organic matters in the sewage.
Preferably, disinfectant 5146 is a sodium hypochlorite disinfectant.
In addition, the particle diameters of the activated carbon particles and the decontamination particles 514 are larger than the diameter of the through holes 510, so that the activated carbon particles and the decontamination particles 514 are prevented from being discharged out of the sand casting column 509 through the through holes 510, the utilization rate of the activated carbon particles and the decontamination particles 514 is improved, and the waste of the activated carbon particles and the decontamination particles 514 is avoided.
When the filter material layer 402 is back washed, the telescopic cylinder 502 is controlled to have frequency telescopic, the connector 503 and the guide block 505 are driven to slide in the guide piece 504 when the telescopic cylinder 502 stretches, and the movable ball 507 in the connector 503 also drives one end of the sand-stirring column 509 to swing under the action of the connecting column 508, the connecting sleeve 512 and the fixing bolt 513. The oscillating sand casting column 509 loosens the filter material layer 402, avoids excessively compacting the filter material layer 402, and further has enough gaps between the filter material layers 402 to discharge impurities when the filter material layer 402 is backwashed, avoids residual impurities in the filter material layer 402, and greatly improves the backwashing effect of the filter material layer 402.
In the present application, the foundry column 509 has two swinging modes, such as a pair of telescopic cylinders 502 synchronously telescopic, and the foundry column 509 will reciprocate parallel to the supporting layer 4, i.e. the state shown in fig. 3. If a pair of telescopic cylinders 502 do not extend synchronously, i.e. one telescopic cylinder 502 extends, and the other telescopic cylinder 502 contracts, the sand-casting column 509 is made of elastic material and has elasticity, and the sand-casting column 509 swings back and forth in an inclined manner, i.e. the state shown in fig. 7-8.
In addition, because the sand-casting column 509 and the movable ball 507 can rotate, when the sand-casting column 509 loosens the filter material layer 402, the condition of hard extrusion can be avoided, so that the sand-casting column 509 can loosen the filter material layer 402 more easily, and the damage probability of the sand-casting column 509 is greatly reduced.
In addition, the application is also provided with activated carbon particles and decontamination particles 514 in the sand casting column 509, when the filter filters sewage, part of sewage can enter the sand casting column 509 through the through holes 510 and contact with the activated carbon particles and the decontamination particles 514, organic substances, pigments and peculiar smell substances in the sewage can be adsorbed and removed by the activated carbon particles, and bacteria, viruses and decomposed organic substances in the sewage can be removed by the decontamination particles 514.
That is, the sewage enters the inner side of the inner membrane 5141 through the fine holes 5144, the water absorbing layer 5143 absorbs part of the sewage and expands, so that the whole volume of the decontamination particles 514 is enlarged, when the decontamination particles 514 expand, the diameter of the capillary 5147 is enlarged, the disinfectant 5146 can be slowly released, and bacteria, viruses and decomposed organic matters in the sewage can be removed by using the released disinfectant 5146. Meanwhile, the adsorption layer 5145 can also adsorb suspended matters and impurities in the sewage, so as to achieve the effect of filtering the sewage.
When the filter material layer 402 is backwashed, the rotating sand casting column 509 can also swing the activated carbon particles and the decontamination particles 514, so that the activated carbon particles and the decontamination particles 514 randomly run in the sand casting column 509, impurities adsorbed on the surfaces of the activated carbon particles and the decontamination particles 514 can be separated from the activated carbon particles and the decontamination particles 514 under the action of rotating centrifugal force or collision, further, the integral backwashed effect of the filter material layer 402 can be greatly improved, and meanwhile, the utilization rate of the activated carbon particles and the decontamination particles 514 can also be improved.
