Water intake head capable of preventing evacuation of siphon

Abstract

The invention relates to a water intake head capable of preventing evacuation of a siphon. The water intake head provided by the invention comprises a chamber body, a floating ring, a bent pipe, a damage vacuum mechanism and a sealing mechanism, wherein the chamber body is hollow, the floating ring is fixed around peripheries of the lower part of the chamber body, and a pull rope is tied on the upper end of the chamber body; a check valve and an exhaust pipe with an exhaust valve are disposed on the bent pipe; the damage vacuum mechanism comprises an insertion pin, an upper floating ball of which the lower part is tired to one end of a transmission rope, as well as a support equipped with a positioning hole in the middle part; and the sealing mechanism comprises a seal plate, a transmission rod, a lower floating ball, a rotation shaft and a positioning rod. According to the invention, a suction hole of the siphon can be sealed automatically when a liquid level descends to a preset position, so that evacuation caused by continuous suction of the siphon can be avoided; and when the water intake head is used next time, the siphon does not need to be filled with water once again, and siphon condition generation conditions induced thereby can be avoided. According to the invention, operations are simple; and changes of the liquid level do not need to be gazed all the time.

Description

technical field [0001] The invention relates to a siphon, in particular to a water intake head capable of preventing the siphon used to suck the supernatant of a mud drying tank from being evacuated. Background technique [0002] At present, most of the domestic waste mud is still treated by natural sedimentation and drying technology. In urban projects, the construction site is small, and the mud is generally transported to the nearby natural sedimentation and drying pool for centralized treatment; in field construction projects, it is far away from the centralized treatment drying pool and there is available or leased open space, and the construction party builds the waste mud naturally. Drying pond; this kind of drying pond is formed by embankment of soil on the construction site, and the mechanism is relatively simple. Due to the slow natural dehydration of the mud, a large area of ​​drying pond is required, which increases the rent, and the drying speed is more affecte...

AI Technical Summary

Problems solved by technology

At present, the way of excavating trenches on the embankment to discharge the supernatant is adopted. If the mud level is low, the trench needs to be dug very deep. If the deepest part of the supernatant in the pool is in the center of the pool, it is difficult to drain the supernatant. , and it is easy to wash away the mud in the dam during discharge, making the drainage turbid

When using a siphon to suck the supernatant, you need to observe it all the time, otherwise the siphon will be evacuated easily, causing the water in the tube to be emptied, and the next time you use it, you need to refill the siphon to form a condition that induces a siphon, and the operation is troublesome
