Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a pulse water distributor.
Background
The bell-jar type pulse water distributor mainly ensures that the activated sludge in the sewage pool is in a stable floating state through a pulse water distribution process, so that the activated sludge is fully contacted with the sewage, namely the contact area of the activated sludge and the sewage is increased, and the treatment efficiency of the sewage is improved.
At present, a common bell-type pulse water distributor usually comprises a water collecting tank, a water inlet, a fixed bell and a central siphon. The sewage is injected into the water collecting tank through the water inlet, and when the water level in the water collecting tank reaches the upper end of the central siphon pipe from the lower end of the fixed bell jar, the sewage starts to flow into the central siphon pipe and gradually takes away the air above the fixed bell jar, so that a siphon effect is generated, and the sewage in the water collecting tank quickly flows into a sewage pool below the bell jar type pulse water distributor through the central siphon pipe. When the water level in the water collecting tank is lowered to the lower end of the fixed bell jar, air enters the fixed bell jar again, the siphon effect is destroyed, and sewage stops entering the central siphon, so that primary pulse water distribution is realized. The lower end of the fixed bell jar is a liquid level for destroying the siphon effect, which can be called a siphon-breaking liquid level, and the upper end of the central siphon tube is a liquid level for generating the siphon effect, which can be called a siphon-generating liquid level.
However, since the position of the fixed bell jar in the bell-type pulse water distributor is not changed, the pulse water volume (i.e. the primary water volume from the time when the sewage starts to flow into the central siphon to the time when the sewage stops flowing into the central siphon) is fixed. This results in that when the water inlet speed changes, the frequency of pulse water distribution changes according to the water inlet speed. For example, when the water inlet speed is increased, the water level in the water collection tank can quickly reach the siphon generation liquid level from the siphon damage liquid level and then descend to the siphon damage liquid level from the siphon generation liquid level, so that the pulse water distribution frequency is increased; when the water inlet speed is slowed down, the water level in the water collection tank needs to spend a long time to reach the siphon generation liquid level from the siphon damage liquid level, and then the water level is reduced to the siphon damage liquid level from the siphon generation liquid level, so that the frequency of pulse water distribution is slowed down.
When the pulse frequency is too fast, the sewage impact force is too large, so that the activated sludge is washed away; when the frequency of the pulse is too slow, the activated sludge cannot form a stable suspended state and cannot be sufficiently contacted with the sewage. All of which reduce the efficiency of sewage treatment.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problem that the bell-type pulse water distributor cannot adjust the frequency of pulse water distribution and the pulse water quantity and improve the sewage treatment efficiency, the embodiment of the invention provides the pulse water distributor. Referring to fig. 1, fig. 1 is a schematic structural diagram of a pulse water distributor according to an embodiment of the present invention. This pulse water distributor includes: a water collecting tank 1, a fixed bell 3 and a central siphon 4.
Wherein, the water collecting tank 1 is provided with a water inlet 2.
And sewage is injected into the water collecting tank 1 through the water inlet 2 until the sewage reaches the liquid level of the siphon generation, and then the sewage is discharged from the water collecting tank 1. When sewage is treated, a plurality of pulse water distributors can be installed to achieve the effect of uniform water distribution.
The fixed bell jar 3 is arranged in the water collecting tank 1.
One end of the central siphon pipe 4 is positioned in the fixed bell jar 3, a gap is left between the central siphon pipe 4 and the fixed bell jar 3, and the height of the central siphon pipe 4 is lower than that of the water inlet 2.
In the embodiment of the invention, the fixed bell jar 3 is fixed in the water collecting tank 1, so that the pulse water distributor has good balance and uniform water distribution, and the fixed bell jar 3 can be fixed at the central position of the water collecting tank 1. When the pulse water distributor is arranged above the sewage pool, the opening of the water collecting tank 1 faces the ground, and the cross section of the fixed bell jar 3 is in an inverted U shape, namely, the opening of the fixed bell jar 3 faces the ground. The fixed bell 3 is fixed on the periphery of one end of the central siphon 4, and a gap is left between the top end of the fixed bell 3 and the upper end of the central siphon 4.
When the liquid level of the sewage reaches the upper end of the central siphon 4 (namely the siphon generation liquid level), the sewage flows into the central siphon 4 through the inside of the fixed bell jar 3 and continuously takes away the air at the upper end of the fixed bell jar 3 in the process of flowing into the central siphon 4, so that the siphon effect is generated, the sewage quickly flows into a sewage pool below the bell jar type pulse water distributor through the central siphon 4 until the liquid level in the water collecting tank 1 reaches the lower end of the fixed bell jar 3 (namely the siphon damage liquid level). At this time, the air in the water collecting tank 1 enters the fixed bell 3 again, the siphon effect is broken, and the sewage stops flowing into the central siphon 4. The process that the sewage liquid level rises from the siphon damage liquid level to the siphon generation liquid level and then falls from the siphon generation liquid level to the siphon damage liquid level can be called as a pulse period, namely, one-time pulse water distribution.
The stationary bell 3 can be fixedly connected to the central siphon 4. As shown in fig. 1, the central siphon 4 is fixed inside the fixed bell 3 by means of a connecting rod 11. In one example, one end of the connecting rod 11 is welded to the inner wall of the fixed bell 3 and the other end of the connecting rod is welded to the outer wall of the central siphon 4. Thereby achieving the fixing of the central siphon 4 inside the fixed bell 3.
And the adjusting bell jar 5 is sleeved outside the fixed bell jar 3, and the opening direction of the adjusting bell jar 5 is the same as that of the fixed bell jar 3. The height of the adjusting bell 5 is greater than the height of the fixed bell 3.
The adjusting bell jar 5 is sleeved outside the fixed bell jar 3, and a gap is reserved between the adjusting bell jar and the fixed bell jar 3. When the pulse water distributor is arranged above the sewage pool, the cross section of the adjusting bell-jar 5 is also in an inverted U shape, and the opening direction of the adjusting bell-jar 5 is the same as that of the fixed bell-jar 3.
After the siphon reaction, when the sewage liquid level drops to the bottom end of the fixed bell jar 3, namely the siphon breaks the liquid level, the air in the water collecting tank 1 enters the fixed bell jar 3 again, so that the siphon effect is broken. The main function of the regulating bell 5 is to regulate the pulse period and the amount of pulsed water by regulating the height of the siphon break level. Specifically, when the adjusting bell jar 5 is installed outside the fixed bell jar 3, the fixed bell jar 3 and the adjusting bell jar 3 jointly form a combined bell jar, and the combined bell jar is used for completing pulse water distribution.
Specifically, when the position of the adjusting bell jar 5 is adjusted to be low, the liquid level of air entering the fixed bell jar 3 again is adjusted to be low, namely, the siphon damage liquid level is adjusted to be low, the distance between the siphon damage liquid level and the siphon generation liquid level is increased, sewage reaches the siphon generation liquid level from the siphon damage liquid level and then falls to the siphon damage liquid level from the siphon generation liquid level, the consumed time is prolonged, the pulse period is prolonged, the pulse water distribution frequency is reduced, the pulse water distribution frequency is prevented from being too high, active sludge in a sewage pool is flushed away, and the sewage treatment efficiency is reduced.
When the position of the adjusting bell jar 5 is raised, the liquid level of the air re-entering the fixed bell jar 3 is raised, namely the siphon damage liquid level is raised, so that the distance between the siphon damage liquid level and the siphon generation liquid level is reduced, the sewage reaches the siphon generation liquid level from the siphon damage liquid level and then falls to the siphon damage liquid level from the siphon generation liquid level, the spent time is reduced, the pulse cycle time is shortened, the frequency of pulse water distribution is raised, the frequency of pulse water distribution is prevented from being too low, the activated sludge in the sewage pool cannot form a stable suspension state, and the sewage treatment efficiency is reduced.
And the adjusting assembly 6 is fixedly connected with the adjusting bell 5, and the height difference between the opening of the adjusting bell 5 and the opening of the fixed bell 3 is adjusted to adjust the liquid level for breaking the siphon.
The adjusting assembly 6 is connected with the adjusting bell jar 5, the lifting of the adjusting bell jar 5 can be realized through the adjusting assembly 6, the height difference between the opening of the adjusting bell jar 5 and the opening of the fixed bell jar 3 is adjusted, namely, the height difference between the liquid level of the generated siphon and the liquid level of the broken siphon is adjusted, so that the pulse period and the pulse water quantity of the pulse water distributor are adjusted according to different water inlet speeds, for example, the adjusting bell jar 5 is reduced through the adjusting assembly 6 when the water inlet speed is increased, and the adjusting bell jar 5 is lifted through the adjusting assembly 6 when the water inlet speed is decreased. Thereby realizing uniform water distribution and improving the sewage treatment efficiency.
In one embodiment, the adjusting assembly 6 may include: an adjusting screw 61, an adjusting hand wheel 62 and an adjusting nut 63.

The user can change the position of adjusting the bell jar 5 by rotating the adjusting hand wheel 62, so as to realize uniform water distribution and improve the sewage treatment efficiency.
In one embodiment, the adjusting assembly 6 may further comprise: the nut 64 is fixed. The fixing nut 64 is fixed at the top end of the adjusting bell jar 5, and the fixing nut 64 is fixedly connected with the adjusting screw 61, so that the adjusting screw 61 is fixedly connected with the top end of the adjusting bell jar 5, and the adjusting bell jar 5 can be conveniently detached.
As shown in fig. 1, the adjusting screw 61 penetrates through the top end of the water collecting tank 1, one end of the adjusting screw 61 is fixedly connected with the adjusting hand wheel 62, the other end of the adjusting screw 61 is fixedly connected with the fixing nut 64 in a welding manner, so that the adjusting bell jar 5 is fixedly connected with the adjusting screw 61, a first through hole is formed in the top end of the water collecting tank 1, the adjusting nut 63 is installed above the first through hole, the adjusting nut 63 is in threaded fit with the adjusting screw 61, the adjusting screw 61 can simultaneously penetrate through the first through hole and the adjusting nut 63 for ensuring that the adjusting screw 61 coincides with the axis of the adjusting nut 63. When the adjusting hand wheel 62 is rotated clockwise or counterclockwise, the adjusting hand wheel 62 drives the adjusting screw 61 to ascend or descend, at the moment, the adjusting bell jar 5 fixedly connected with one end of the adjusting screw 61 ascends or descends along with the adjusting screw 61, so as to adjust the height difference between the opening of the adjusting bell jar 5 and the opening of the fixed bell jar 3, thereby changing the pulse period and the pulse water volume of the pulse water distributor.
