Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a bell-type pulse water distributor device. Background Art

[0002] During the use of a water treatment device, some processes require periodic rapid water distribution to achieve functions such as stirring and other process requirements. Currently, pulse water distributors are mainly used in hydrolysis acidification and anaerobic processes, combined with the water distribution system at the bottom of the pool and the reflux system in the pool, to fully mix sewage and sludge, improve sewage treatment efficiency, and can replace traditional submersible agitators.

[0003] The early pulse water distributor adopted an inverted U-shaped siphon. Its working principle is as follows: After sewage enters the water tank, the water level gradually rises. When the water level rises to the interface between the water distribution main pipe and the siphon, when the water flows rapidly through the siphon, air is continuously carried away by the water flow through the siphon auxiliary pipe. Eventually, a vacuum is formed above the water distribution main pipe, and the water distribution main pipe forms a siphon. The water in the water tank rapidly flows away through the water distribution main pipe, and the water level drops rapidly. When the water level drops to the pipe orifice of the siphon break pipe, air enters the upper end of the water distribution main pipe, and the siphon of the water distribution main pipe is destroyed, and the siphon stops, entering the next cycle.

[0004] The inverted U-shaped siphon pulse water distributor mainly has the following disadvantages:

[0005] 1. The siphon pipe diameter is small, and it is extremely easy to be blocked, resulting in the inability to generate pulses.

[0006] 2. When the water inflow is too small, it may be impossible to generate pulse water distribution, and it has poor adaptability to water volume changes.

[0007] 3. There is no exhaust device, which will bring in air and have an adverse impact on the sewage treatment effect.

[0008] To solve the above problems, the utility model provides a bell-type pulse water distributor device. Utility Model Content

[0013] As a further technical solution of the present utility model, the lower half sections of the siphon and the auxiliary siphon both pass through the installation platform and extend into the water surface. The upper end of the siphon has a certain distance from the inner top of the bell and does not contact the inner top of the bell.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 , the present utility model provides a technical solution for a bell - type pulsed water distributor device: A bell - type pulsed water distributor device includes a water tank 1. The water tank 1 is fixed on an installation platform through four legs 9. An inspection hole 10 is provided at the top of the water tank 1, and the lower end of the outer side of the water tank 1 is communicated with a water inlet 6. The water tank 1 is divided into three parts: the top, the straight cylinder, and the bottom. The top is divided into a circular ring inclined side plate and an inspection hole 10. There is a water inlet 6 on the side of the straight cylinder part. The bottom is divided into a middle circular bottom and two inclined circular ring side plates on both sides. The four legs 9 are evenly distributed on the bottom side plates and are welded to the circular ring side plates. The bell 2 is welded to the center of the circular part at the bottom of the water tank 1 through four support columns. The upper half of the siphon pipe 3 passes through the center of the circular bottom of the water tank 1 and is welded to the circular part at the bottom of the water tank 1. The pipes inside and outside the water tank 1 are connected by flanges, which are detachable, simple to install, and convenient for transportation.

[0028] Four support columns are installed at the center of the inner bottom of the water tank 1. A bell jar 2 is connected to the four support columns together. The bell jar 2 is in the shape of an inverted straight cylinder, and the upper part of the bell jar 2 is closed and the lower part is open. The water tank 1, the bell jar 2 and the siphon 3 are arranged coaxially. The four support columns are equally spaced at the center of the inner bottom of the water tank 1, and there is a spacing between every two support columns. There is a spacing between the lower port of the bell jar 2 and the inner bottom of the water tank 1, and this distance is directly related to the flow rate. The siphon 3 and the auxiliary siphon 4 are nested, occupying less space in the water tank 1 and increasing the water storage space of the water tank 1. The position where the auxiliary siphon 4 opens on the siphon 3 determines the siphon water inlet time, and the height of the lower port of the bell jar 2 determines the siphon end time;

[0029] The siphon 3 is arranged inside the bell jar 2. The upper half of the siphon 3 passes through the bottom of the water tank 1 and is welded to the bottom of the water tank 1. The upper half of the siphon 3 and the lower half outside the water tank 1 are connected by a flange. The lower half segments of the siphon 3 and the auxiliary siphon 4 both pass through the installation platform and extend into the water surface. There is a certain distance between the upper end of the siphon 3 and the inner top of the bell jar 2 and they do not contact each other. This distance is directly related to the flow rate of the siphon 3. The cross-sectional area and flow rate of the siphon 3 determine the flow velocity;

[0030] An auxiliary siphon 4 and an auxiliary destruction pipe 5 are arranged inside the siphon 3. The auxiliary destruction pipe 5 is located inside the siphon 3 and is welded to the auxiliary siphon 4. The pipe orifice of the auxiliary siphon 4 is welded to the siphon 3. The auxiliary siphon 4 is detachable, and its upper half and lower half are tightly connected by a pipe thread. Drain pipes 8 and exhaust pipes 7 are respectively arranged on both sides of the bottom of the water tank 1. The upper half of the exhaust pipe 7 extends through the water tank 1, and the lower half passes through the installation platform and is exposed to the air. The upper half pipe orifice of the exhaust pipe 7 is higher than the highest water level inside the water tank 1. The upper half of the drain pipe 8 extends into the water tank 1 and is communicated with it. A valve is installed on the lower half of the drain pipe 8. When the water tank 1 needs to be cleaned and repaired or is not used for a long time, the water tank 1 can be emptied by opening the valve on the drain pipe 8, and the inside of the water tank 1 can be cleaned and repaired through the inspection hole 10. The inspection hole 10 is sealed with a flange blind plate.

[0031] The working principle of the present utility model is as follows: Water flow continuously enters the water tank 1 first, and at the same time enters its inner cavity from the lower part of the bell jar 2. The water levels in the water tank 1 and the bell jar 2 start to rise synchronously and evenly and are at the same water level; As the water level rises, the air in the upper part of the water tank 1 is discharged from the water tank through the exhaust pipe 7, and a part of the air in the bell jar is pressed into the lower pool, and a part rises to the top of the bell jar;

[0032] When the water level rises into the bell jar 2 and reaches the opening position of the auxiliary siphon pipe 4 on the siphon pipe 3, water begins to flow out of the auxiliary siphon pipe 4 quickly into the lower water pool. With the suction effect of the water, the air compressed at the top of the bell jar 2 is carried away by the flowing water through the auxiliary breaking pipe 5, so that a negative pressure space is formed in the upper part of the bell jar 2.

[0033] The water tank 1 continues to flow in, and the opening position of the auxiliary siphon tube 4 on the siphon tube 3 is very close to the upper opening position of the siphon tube 3. The pressure difference between the inside and outside of the bell jar 2 causes the water level in the bell jar 2 to rise rapidly to the upper opening position of the siphon tube 3 and then begin to quickly enter the lower water pool;

[0034] The water discharged through the large-diameter siphon 3 and the small-diameter auxiliary siphon 4 forms a negative pressure state on the top of the bell jar 2; under the action of the negative pressure, the water in the water tank 1 is quickly sucked into the bell jar 2 in large quantities and quickly flows out through the siphon 3, the negative pressure in the bell jar 2 is further increased, the water outflow is greater than the water inflow, the water in the water tank 1 is rapidly reduced in a short period of time, and the water level difference with the bell jar 2 is increased;

[0035] When the water level in the water tank 1 drops to the lower edge of the bell jar 2, the bell jar 2 is connected to the water tank 1, and air enters the upper part of the bell jar 2, destroying the negative pressure in the upper part of the bell jar 2. The air pressure inside and outside the bell jar 2 forms a balanced state, and the water level in the bell jar 2 is the same as the water level in the water tank 1. The siphon is destroyed and the pulse water distribution stops;

[0036] When the water level in the bell jar reaches the opening position of the auxiliary siphon tube 4 on the siphon tube 3, the next siphon is formed and the pulse water distribution process begins, thereby realizing the conversion of continuous water inflow in the water tank 1 into periodic instantaneous pulse water distribution function in the water pool.

[0037] When siphon pulse occurs, due to the high water flow rate, water distribution can be completed in a short time (designed to be 30s), achieving the pulse effect, stirring up the sludge at the bottom of the pool, and promoting the full mixing of raw water, filler and sludge in the pool, so that pollutants in the raw water can fully contact with microorganisms in the pool, promoting biochemical reactions, and avoiding sludge precipitation;

[0038] If the equipment needs to be cleaned and overhauled or is not used for a long time, the water tank 1 can be emptied through the valve on the vent pipe 8, and the inside of the water tank 1 can be cleaned and overhauled through the inspection hole 10.

[0039] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
