Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a quartz sand filter control valve with an anti-blocking function. Background Art

[0002] Quartz sand filter, scientific name, it uses quartz sand as filter medium, under a certain pressure, to filter water with high turbidity through granular or non-granular quartz sand of a certain thickness, effectively intercepting and removing suspended matter, organic matter, colloid particles, microorganisms, chlorine, odor and some heavy metal ions in the water, and finally achieving the effect of reducing water turbidity and purifying water quality. It is a kind of high-efficiency filtering equipment.

[0003] The currently published patent: CN206045508U discloses a new type of quartz sand filter device. The control valve 1321 of the water inlet pipe and the control valve of the main drain pipe 1532 are opened. The water flows through the control valve 1321 of the water inlet pipe after being pressurized by the external booster device, and then passes through the water inlet 132, and then evenly distributes the water through the water divider 134, and then passes through the multi-layer filter filler in the filter body 11, so that the water is filtered in the step-by-step change of the filter material when passing through the filler layer, making the outlet water cleaner, and then reaches the main drain pipe 1532 through the drain port 153, and finally reaches the next step process.

[0027] The control valve 4 is internally rotatably connected with a sealing ball 6, and a drainage hole 7 is provided on the surface of the sealing ball 6. The size of the drainage hole 7 is the same as that of the through hole 5.

[0028] The surface of the sealing ball 6 is fixedly connected with a rotating shaft 8, the upper end of the rotating shaft 8 rotates through the inside of the control valve 4 and extends to the outside, and the upper end of the rotating shaft 8 is fixedly connected with a circular rotating disk 9;

[0030] The staff rotates the rotating shaft 8 through the circular turntable 9, and the rotation of the rotating shaft 8 can drive the sealing ball 6 to rotate. The sealing ball 6 rotates and makes the drain hole 7 connected with the water inlet pipe 3. The control valve 4 is in the open state. After the sewage flows into the interior of the filter tank 1 through the water inlet pipe 3, the sewage first passes through the wire mesh 11 and then passes through the quartz sand filter block 10 to filter impurities. The filtered sewage flows to the bottom of the filter tank 1 and is finally discharged to the outside through the drain pipe 2. When impurities are blocked in the drain hole 7, the staff can rotate the sealing ball 6 ninety degrees through the circular turntable again, thereby connecting the drain hole 7 with the through hole 5, and the control valve 4 is in the closed state. At this time, the staff can transport the impurities inside the drain hole 7 through the through hole 5. When the control valve 4 is blocked, it can be immediately unblocked to prevent impurities from being blocked in the control valve 4, thereby improving the water passing efficiency of the control valve 4.

[0034] After the staff starts the sludge pump 15, the ring 12 and the sludge pipe 13 can extract the sludge on the surface of the wire mesh 11, and the multiple sludge pipes 13 are distributed in a ring shape to improve the efficiency of sludge extraction, and discharge it to the outside through the sludge hose 16 and the sludge pump 15. The top of the quartz sand filter block 10 is a wire mesh 11 to prevent quartz sand particles from being extracted to the outside, which makes it convenient for the staff to clean the sludge on the top of the quartz sand filter block 10, avoid sludge clogging the top of the quartz sand filter block 10, maintain the cleanliness of the top of the quartz sand filter block 10, and thus improve the filtration efficiency of the quartz sand filter block 10 for sewage.

[0035] Working principle: for the quartz sand filter control valve with anti-blocking function, the staff rotates the rotating shaft 8 through the circular turntable 9. The rotation of the rotating shaft 8 can drive the sealing ball 6 to rotate. The sealing ball 6 rotates and makes the drainage hole 7 connected with the water inlet pipe 3. The sewage flows into the interior of the filter tank 1 through the water inlet pipe 3 and then passes through the quartz sand filter block 10 to filter impurities. When impurities are blocked in the drainage hole 7, the staff can rotate the sealing ball 6 ninety degrees through the circular turntable again, so that the drainage hole 7 is connected with the through hole 5. At this time, the staff can transport the impurities in the drainage hole 7 through the through hole 5. After the staff starts the sludge pump 15, the ring 12 and the sludge pipe 13 can extract the sludge on the surface of the wire mesh 11, and discharge it to the outside through the sludge hose 16 and the sludge pump 15. The top of the quartz sand filter block 10 is the wire mesh 11 to prevent the quartz sand particles from being extracted to the outside, so that the staff can clean the sludge on the top of the quartz sand filter block 10 conveniently.
