(2) In the first stage of sedimentation, the first sedimentation tank 5 is filled with water, and the second sedimentation tank 6 is closed. When water enters the first sedimentation tank 5 and exceeds a preset designed water level, the water enters the floating ball cylinder 15 from the floating ball cylinder water inlet 152, the floating ball 16 rises to drive the pressure rod 13 to press the top block 24, the first water outlet 112 of the water inlet valve 11 is closed, the second water outlet 113 is opened under the action of the connecting rod 116, at this time, the first combination valve 20 of the water outlet valve 19 of the first sedimentation tank 5 is closed (the water level of the second sedimentation tank does not reach a preset designed height, and the floating ball 16 in the second sedimentation tank does not rise), because the water level of the first sedimentation tank 5 exceeds the preset designed water level, the floating ball cylinder 15 connected with the second combination valve 21 enters water from the floating ball cylinder water inlet 152, the floating ball 16 rises, the second combination valve 21 is in an open state, but the water outlet valve 19 of the first sedimentation tank 5 is still closed, in the embodiment, any one of the first combination valve 20 and the second combination valve 21 is closed, and the water outlet valve 19 is closed.
(3) And in the second stage of sedimentation, the first sedimentation tank 5 is kept stand, and the second sedimentation tank 6 is filled with water.
(4) In the third stage of sedimentation, the first sedimentation tank 5 discharges water, and the second sedimentation tank 6 continues to feed water. When the water level of the second sedimentation tank 6 reaches the designed preset water level after a period of time, the floating ball 16 in the second sedimentation tank 6 rises to open the first composite valve 20 of the water outlet valve 19 of the first sedimentation tank 5, as shown in step (1), the second composite valve 21 in the first sedimentation tank 5 is in an open state, and when the first composite valve 20 is opened, the water outlet valve 19 of the first sedimentation tank 5 is opened, and water flows to the filtering tank 7. The predetermined water level is usually designed according to the water inlet speed, and is generally half to two thirds of the highest water level, and the reserved water level of the second sedimentation tank 6 is used for continuing water inlet before the first sedimentation tank 5 finishes water outlet.
(5) And in the fourth stage of precipitation, the first precipitation tank 5 is filled with water, and the second precipitation tank 6 is kept standing for precipitation. When the water level of the first sedimentation tank 5 falls to a designed low value, the floating ball 16 in the floating ball valve 17 in the first sedimentation tank 5 falls to open the water outlet 153 of the floating ball cylinder, the floating ball 16 in the floating ball cylinder 15 falls, the first water outlet 112 of the water inlet valve 11 is opened, the second water outlet 113 is closed, at this time, as the floating ball valve 17 opens the water outlet of the floating ball cylinder 15 and the water level of the first sedimentation tank 5 is at the low value, the water of the floating ball cylinder 15 of the second combination valve 21 is controlled to flow out, the second combination valve 21 is closed, the water outlet valve 19 is closed, the first sedimentation tank 5 starts to feed water, and after the water level continues to rise, the floating ball valve 17 closes the water outlet 153 of the floating ball cylinder, the water level in the floating ball cylinder 15 cannot continue to rise, and the closing of the water outlet valve 19 is maintained.
(6) In the fifth stage of sedimentation, the first sedimentation tank 5 feeds water, and the second sedimentation tank 6 feeds water. When the water level of the first sedimentation tank 5 rises to a designed certain water level, for example, 2/3, the floating ball 16 (arranged in the first sedimentation tank 5) of the first combination valve 20 of the water outlet valve 19 of the second sedimentation tank 6 rises, the first combination valve 20 is opened, because the water level of the second sedimentation tank 6 is at a high level, the second combination valve 21 of the second sedimentation tank 6 is in an opened state, the water outlet valve 19 of the second sedimentation tank 6 is opened, the second sedimentation tank 6 starts to discharge water, after the water level of the second sedimentation tank 6 is reduced to a low value, the second combination valve 21 of the second sedimentation tank 6 is closed, the first sedimentation tank 5 continues to discharge water to a preset water level, water enters from the water inlet 152 of the cylinder of the first sedimentation tank 5, so that the first water outlet 112 of the floating ball 11 is closed, and the second water outlet 113 is opened.
(7) And the process is circulated to realize the alternate sedimentation of the two sedimentation tanks.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
