Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a siphon device for a diversion water distributor in a hydrolysis acidification tank. Background Art

[0002] Currently, common water distributors have multiple structures. The basic principle is: use the fast-flowing water in the siphon to take away the air in the water distribution main, so that the water distribution main forms a certain vacuum degree. Under the action of the atmospheric pressure difference inside and outside the water distribution main, the water in the container enters the water distribution main and is discharged into the acidification tank. Due to the fast water flow speed, the water distribution is completed in a very short time.

[0003] For example, in the Chinese utility model patent document with the authorization announcement number CN207581461U, an improved siphon pulse water distributor is disclosed, which includes a cylinder, supporting legs, a water distribution main pipe, a siphon pipe group and other structures, wherein the water distribution main pipe is an inverted U-shaped structure, the water outlet end extends outside the cylinder and extends to the bottom of the hydrolysis acidification tank, the inlet end extends into the vicinity of the bottom of the cylinder, the siphon destroying pipe in the siphon is connected to the siphon pipe, and the other end extends into the vicinity of the bottom of the cylinder. When working, it can distribute water quickly.

[0018] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] The utility model provides a siphon device for a water distributor of a hydrolysis acidification tank. As shown in the figure, the device includes a tank body and a siphon mechanism arranged in the tank body. The tank body is provided with a main water inlet 7, a backwash water inlet 8 and an auxiliary agent addition port 11 are provided on the peripheral wall of the tank body, and an observation hole 9 is provided on the top wall of the tank body. The main water inlet 7 is used for the entry of untreated raw water from the outside, the backwash water inlet 8 is used for the entry of clean water from the outside, and the auxiliary agent addition port 11 is used for the injection of specific drugs to improve the filtration efficiency or perform specific treatment, such as disinfectants, flocculants, etc. The observation hole 9 is used to monitor the state inside the tank body so as to perform backwash tank washing operations as needed.

[0020] The siphon mechanism includes a water distribution main pipe 1 with a U-shaped structure located in the tank body, a siphon pipe 2 located in the tank body, a stop pipe 3 located in the tank body, and an auxiliary pipe 4 located in the tank body. The water inlet end of the water distribution main pipe 1 is located in the tank body and extends downward, and the water outlet end extends downward out of the tank body. The water inlet end height of the water distribution main pipe 1 is higher than the water outlet end height. One end of the siphon pipe 2 is connected to the water outlet end side of the water distribution main pipe 1, and the other end extends downward out of the tank body. The port height of the siphon pipe 2 extending out of the pipe body is higher than the water outlet end height of the water distribution main pipe 1. One end of the auxiliary pipe 4 is connected to one side of the siphon pipe 2, and the middle part of the auxiliary pipe 4 is connected to the top of the water distribution main pipe 1 through the emptying pipe 6. The other end of the auxiliary pipe 4 is connected to one end of the stop pipe 3. The other end of the stop pipe 3 is located in the tank body and extends downward. The auxiliary pipe 4 is provided with an exhaust hole 5 with a one-way valve, and the stop pipe 3 is provided with a valve to control its opening and closing. Further, the siphon pipe 2 is L-shaped.

[0021] The backwash water inlet 8 is provided with a first butterfly valve for controlling its opening and closing. The auxiliary agent addition port 11 is provided with a second butterfly valve for controlling its opening and closing. The main water inlet 7 is provided with a third butterfly valve for controlling its opening and closing.

[0022] The inner diameter of the siphon pipe 2 is smaller than the inner diameter of the water distribution main pipe 1. An emptying port 10 is provided at the bottom of the tank body and a fourth butterfly valve opened and closed by a controller is provided on the emptying port 10.

[0023] The working principle of this device is:

[0024] The exhaust hole 5 is used to exhaust the internal air of the water distribution main pipe 1 as the water level rises, thereby forming a vacuum state. The one-way valve of the exhaust hole 5 is used to only exhaust air but not to intake air.

[0025] When the valve of the stop pipe 3 is in the open state, the pressure difference generated by the siphon will be the same as that outside, and no negative pressure will be generated. When the valve of the stop pipe 3 is closed, negative pressure will be generated, destroying the formation of the siphon.

[0026] The siphon pipe 2 is connected to the water distribution main pipe 1. When the water level reaches the position of the siphon pipe 2, it flows out to form a negative pressure to increase the water flow into the water distribution main pipe 1, so that the water distribution main pipe 1 quickly forms a siphon.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
