[0012] Further, the bottom opening of the bell jar is not in contact with the inner bottom of the cylinder.

[0013] The utility model discloses the beneficial effect:

[0014] Through the design of the water inlet assembly, when the sewage water inlet quantity is large, valve two can be opened and valve one can be closed, so that the sewage water flows directly into the cylinder, when the sewage water inlet quantity is small, valve one can be opened and valve two can be closed, so that the sewage water can enter the automatic flushing water bucket and be temporarily stored, and after being stored to the full capacity, the automatic flushing water bucket is automatically poured into the cylinder, the change from small-flow continuous water inlet to large-flow intermittent water outlet is realized, the water distributor can also be applicable to the place with large sewage treatment capacity, and is especially applicable to the place with small and changeable sewage treatment capacity when fine chemical industry is switched to multiple varieties and multiple projects.

[0015] Through the design of the automatic flushing water bucket, the small-flow continuous water inlet to the cylinder is changed into large-flow intermittent water outlet, so that the short-time water inlet quantity is much larger than the drainage capacity of the siphon pipe, the water level in the bell jar is rapidly raised to the main pipeline, and the siphon water distribution effect is achieved.

[0016] Through the design of the variable-diameter cylinder structure that the diameter of the cylinder is gradually reduced from top to bottom, when the water level in the cylinder is raised to the top of the siphon pipe, the diameter of the cylinder has been reduced, and the water level in the cylinder is rapidly raised when a large amount of sewage is poured into the automatic flushing water bucket again, the same water inlet quantity can provide greater water level pressure, the water level in the bell jar is rapidly raised to the main pipeline, and the siphon water distribution effect is achieved.

[0017] Through the design of the gradually-reduced gradually-enlarged pipe, when the water level in the cylinder is rapidly raised and the sewage in the bell jar is rapidly discharged through the siphon pipe, a gradually-reduced gradually-enlarged pipe is arranged on the upper portion of the siphon pipe, a branch pipe is arranged at the thinnest portion of the pipe and led to the high position of the siphon pipe, the flow rate is increased and the pressure is reduced when passing through the gradually-reduced gradually-enlarged pipe, the air in the bell jar can be rapidly extracted and the pressure in the bell jar is reduced, the water level in the bell jar is rapidly raised to the main pipeline, and the siphon water distribution effect is achieved.

[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0022] Please refer to Figure 1 The utility model provides a bell jar type pulse water distributor technical scheme, including the cylinder 5, the one side of cylinder 5 is connected with water inlet component, the inner middle part of cylinder 5 is fixed with the bell jar 6 of inverted buckle placement, the bottom opening of bell jar 6 and the inner bottom of cylinder 5 are not contacted, the inner bottom center of cylinder 5 is welded with siphon 8 and main pipeline 9, the top end of siphon 8 and main pipeline 9 both extends to the inside of bell jar 6, the bottom end of siphon 8 and main pipeline 9 both extends to the outside of cylinder 5, and the lower end of main pipeline 9 is connected with water distribution pipe arranged in sewage pool.

[0023] Please refer to Figure 1 The water inlet component includes water inlet pipe 1, the water inlet end of water inlet pipe 1 is connected with sewage submersible pump, the both sides output ends of water inlet pipe 1 are equipped with valve one 2 and valve two 3 respectively, valve two 3 communicates with cylinder 5, valve one 2 communicates with water supply pipe, the top output end of water supply pipe is matched with automatic flushing water bucket 4, and automatic flushing water bucket 4 is hinged on one side of the top of cylinder 5. Through the design of water inlet component, when the sewage water inlet quantity is large, valve two 3 can be opened and valve one 2 is closed, so that the sewage flows directly into cylinder 5, when the sewage water inlet quantity is small, valve one 2 can be opened and valve two 3 is closed, so that the sewage can be stored in automatic flushing water bucket 4, and after storage, it is automatically poured into cylinder 5, realizing the change from small flow continuous water inlet to large flow intermittent water outlet, so that the water distributor can also be applicable to the place with large sewage treatment capacity, especially applicable to the place with small and variable sewage treatment capacity when fine chemical industry multiple varieties and multiple projects are switched.

[0024] Please refer to Figure 1 The top side of the outer surface of cylinder 5 is equipped with limiting top rod matched with automatic flushing water bucket 4. Through the design of limiting top rod, the stability of automatic flushing water bucket 4 is improved.

[0025] Please refer to Figure 1The top end of the siphon 8 is connected with the tapered pipe 7. Through the design of the tapered pipe 7, when the water level in the cylinder 5 is rapidly raised and the sewage in the bell jar 6 is rapidly flowed out through the siphon 8, the air in the bell jar 6 is rapidly discharged, the pressure is reduced, and the water level is raised to above the main pipeline 9 with the help of the tapered pipe 7.

[0026] Referring to Figure 1 The cylinder 5 is a variable-diameter cylinder structure with a small diameter at the top and a large diameter at the bottom. Through the design of the variable-diameter cylinder structure with a small diameter at the top and a large diameter at the bottom, when the water level in the cylinder 5 is raised to above the siphon 8, at this time, because the diameter of the cylinder 5 has been reduced, with the automatic flushing water tank 4 pouring a large amount of sewage again, the water level in the cylinder 5 will rapidly rise, the same water inflow can provide greater water level pressure, so that the water level in the bell jar 6 rapidly rises to the main pipeline 9, achieving the siphon water distribution effect.

[0027] In use, when the sewage treatment capacity is small, valve one 2 is opened and valve two 3 is closed. The sewage from the flow equalization tank is pumped into the automatic flushing water tank 4 of the pulse water distributor through the water inlet pipe 1 using the submersible sewage pump. The sewage is poured into the cylinder 5 through the automatic flushing water tank 4 from continuous small flow to intermittent large flow. The water level in the cylinder 5 gradually and slowly rises. When the water level reaches above the siphon 8, the diameter of the cylinder 5 has been reduced. With the automatic flushing water tank 4 pouring a large amount of sewage again, the water level in the cylinder 5 rapidly rises. The sewage in the bell jar 6 is rapidly flowed out through the siphon 8. With the help of the tapered pipe 7, the air in the bell jar 6 is rapidly discharged, the pressure is reduced, and the water level is raised to above the main pipeline 9. At this time, the main pipeline 9 forms a siphon effect. The sewage in the entire cylinder 5 is rapidly flowed into the anaerobic sewage tank through the main pipeline 9. When the water level is lowered to below the bell jar 6, air enters the bell jar 6, destroying the siphon effect, and the main pipeline 9 no longer flows water, entering the next pulse period. The rapidly flowed sewage in the main pipeline 9 fully stirs the activated sludge settled at the bottom of the tank. The organic matter in the sewage fully reacts with the anaerobic bacteria in the sludge, completing the sewage treatment.
