Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a filtration equipment for water treatment system, including

water tank

1, 1 bottoms of water tank are provided with first drain pipe 3, and 3 departments of first drain pipe are provided with first cut-off valve 5, install water inlet cavity 2 in the 1 box of water tank, and water inlet cavity 2 is vertical to be fixed in middle part in the 1 interior water tank of water tank. The water inlet cavity 2 is provided with a filter screen communicated with the inside of the water tank 1, the upper end of the water inlet cavity 2 extends out of the side wall of the water tank 1 and is provided with a water inlet 23, and the upper cover of the water inlet cavity 2 is provided with a cover plate 26. Sewage flows into water inlet cavity 2 from water inlet 23 to the drainage after filtering through the filter screen is discharged from first drain pipe 3 of bottom in water tank 1, and at this moment, particulate matters such as impurity in the sewage are precipitated in water inlet cavity 2 by the filter screen separation.

Referring to fig. 2, a drain outlet 21 is arranged at the bottom of the water inlet cavity 2, the drain outlet 21 extends out of the water tank 1, a second water interception valve 6 is arranged at a part of the drain outlet 21 extending out of the water tank 1, the second water interception valve 6 can control the drain outlet 21 to be closed and opened, when sewage is in a filtering state, the second water interception valve 6 is in a closed state, and one end of the water inlet cavity 2 close to the bottom of the water tank 1 is in a conical shape which is gradually reduced from top to bottom. The bottom outside the water tank 1 is provided with a collecting tank 22 which is opposite to the sewage draining outlet 21 and is used for collecting waste water. The filter screen includes first filter screen 8 and second filter screen 7, first filter screen 8 and second filter screen 7 interval from bottom to top set up, and second filter screen 7 presses close to 1 top of water tank and sets up, it communicates each other in first filter screen 8 and second filter screen 7 and the water tank 1 to remove in the cavity 2 to intake, the lateral wall at other positions all does not lead to water, water gets into behind the cavity 2, only can arrange to the water tank 1 from the filter screen in, it is provided with first water level alarm 9 on the lateral wall between first filter screen 8 and second filter screen 7 in the cavity 2 to intake, first water level alarm 9 is close to one side setting of second filter screen 7, and be provided with first pilot lamp 11 with first water level alarm 9 intercommunication on the lateral wall of water tank 1.

Further, a second water level alarm 10 is arranged at the top in the water tank 1, and a second indicator light 12 communicated with the second water level alarm 10 is arranged outside the water tank 1.

When particles such as impurities in the water inlet cavity 2 are blocked to a certain degree by the first filter screen 8, the first filter screen 8 in the water inlet cavity 2 is blocked by the impurities, so that the filtering speed of the first filter screen 8 is lower than the speed of sewage entering the water inlet cavity 2, the water level of the sewage in the water inlet cavity 2 continuously rises, when the water level rises to the position of the first water level alarm 9, the first water level alarm 9 gives an alarm and the first indicator lamp 11 flickers to remind a worker of the operation of sewage discharge on the water inlet cavity 2, at the moment, the worker closes the first water cutting valve 5 to prevent the water in the water tank 1 from being discharged, then the water level continuously rises, the sewage higher than the first water level alarm 9 starts to be filtered through the second filter screen 7 and flows into the water tank 1, when the water in the water tank 1 rises to the second water level alarm 10 to give an alarm, namely, the second indicator lamp 12 flickers, the staff opens second cut-off valve 6 for granule precipitate such as the internal impurity of case 1 that intakes is discharged to collecting pit 22 from drain 21, and simultaneously, at the in-process of blowdown, the water pressure of intaking in the cavity 2 is less than the water pressure in the water tank 1, make and form the negative pressure between intake cavity 2 and the water tank 1, drainage in the water tank 1 flows back to intake cavity 2 through the filter screen in, and erode the filter screen surface, the blowdown that intakes cavity 2 goes on more thoroughly, after the blowdown, with second cut-off valve 6 closed, open first cut-off valve 5 again, can continue to carry out the filtration of sewage (refer to fig. 3).
