[0017] 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.

[0018] The utility model provides a water diversion distributor for a hydrolysis acidification tank, as shown in the figure, comprising a dispersion cone disk 1, a drainage plate 2 and a horn 3, the horn 3 is sleeved on the outer side of the dispersion cone disk 1, a water flow channel is formed between the horn 3 and the dispersion cone disk 1, the drainage plate 2 is located between the horn 3 and the dispersion cone disk 1, the drainage plates 2 are arranged at equal intervals along the circumferential direction of the outer peripheral wall of the dispersion cone disk 1, so as to divide the dispersion cone disk 1 into a plurality of equal diversion channels along the circumferential direction, the tip of the dispersion cone disk 1 is defined as the upper end and the open end as the lower end, the upper ends of the plurality of drainage plates 2 extend upward to intersect at the tip of the dispersion cone disk 1, the lower ends of the drainage plates 2 extend downward to extend to the lower end of the crushing cone disk, the front and rear sides of the drainage plates 2 are respectively connected to the dispersion cone disk 1 and the horn 3, so that the outer wall of two adjacent drainage plates 2, the dispersion cone disk 1 and the inner wall of the horn 3 form a water flow channel after cooperation.

[0019] A through hole connecting the inside and the outside is provided on the top of the horn 3, and the center line of the through hole overlaps with the center line of the horn 3. The device also includes a water inlet pipe 4 and a negative pressure cylinder 5. The negative pressure cylinder 5 is a tubular structure. The negative pressure cylinder 5 is installed at the top of the horn 3 and passes through the through hole. The center line of the negative pressure cylinder 5 overlaps with the center line of the through hole. The water inlet pipe 4 is installed at the top of the negative pressure cylinder 5 and penetrates into the negative pressure cylinder 5. The center line of the water inlet pipe 4 overlaps with the center line of the negative pressure cylinder 5. The water entering from the water inlet pipe 4 can be evenly dispersed through the dispersion cone 1, and gradually decelerates and diffuses due to the conical structure (gradual expansion) of the dispersion cone 1. A second water inlet 6 is provided on the peripheral wall of the negative pressure cylinder 5, and the setting height of the second water inlet 6 is higher than the lower end height of the water inlet pipe 4. When water enters the negative pressure cylinder 5 through the water inlet pipe 4, as the water level rises, a certain water level begins to form inside the negative pressure cylinder 5. When the water level exceeds the second water inlet 6 , external water or gas begins to be sucked into the negative pressure cylinder 5 through the second water inlet 6 under the action of negative pressure, which further increases the negative pressure inside the negative pressure cylinder 5 .

[0020] The second water inlets 6 are arranged at equal intervals along the peripheral wall of the negative pressure cylinder 5. The number of the second water inlets 6 is equal to the number of the diversion channels. The second water inlets 6 and the diversion channels are arranged in a one-to-one correspondence. There is a second water inlet 6 corresponding to the top of any diversion channel so that the water flowing in from the second water inlet 6 can fall into its corresponding diversion channel.

[0021] Fixed orifice plates are arranged at intervals along the circumferential direction on the lower edge of the dispersion cone 1 for fixing to the pool bottom by bolts.

[0022] 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.
