DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the protection scope of the utility model.

[0024] As Figs. 1-3 Indicated, the utility model provides a technical scheme: a sewage treatment hydrolysis acidification tank, including hydrolysis acidification tank 1, top cap, sewage inlet pipe 2 and drain pipe 3, and the detachable fixed connection between hydrolysis acidification tank 1 and top cap, to facilitate opening top cap to clean inside hydrolysis acidification tank 1, the valve is connected on the pipe body of drain pipe 3, and the valve can be selected as manual valve or solenoid valve, when the sewage hydrolysis of hydrolysis acidification tank 1 reaches a certain degree, opens valve, and the hydrolyzed water flows into the next sewage treatment device through drain pipe 3, to facilitate sewage flow, and the inclined block 4 that inclines downward is formed in hydrolysis acidification tank 1, and the L-shaped vertical plate 10 is fixed on one side of inclined block 4, as Fig. 3 Indicated, the U-shaped groove is formed between L-shaped vertical plate 10 and inclined block 4.

[0025] A water outlet groove 101 is formed at the bottom of the L-shaped vertical plate 10, and a gate plate 11 is movably arranged at the inner side of the L-shaped vertical plate 10. Specifically, a plurality of dovetail grooves are formed at the side of the L-shaped vertical plate 10, and a plurality of dovetail blocks are fixed at the side of the gate plate 11 and matched with the dovetail grooves. The gate plate 11 is located at one side of the water outlet groove 101 and used to adjust the opening degree of the water outlet groove 101. When the gate plate 11 is located at the bottom of the water outlet groove 101, the gate plate 11 blocks the water outlet groove 101. A buoyancy ball 12 is fixed at the top of the gate plate 11. With the continuous increase of the sewage in the U-shaped groove, the buoyancy ball 12 moves upward, thereby driving the gate plate 11 to move upward and increasing the opening of the water outlet groove 101, so as to increase the outflow of the sewage and prevent the sewage from overflowing the L-shaped vertical plate 10.

[0026] In order to improve the mixing efficiency between the liquid medicine and the sewage, a liquid medicine inlet pipe 6 is fixed at the top of the hydrolysis acidification tank 1 and communicated with the liquid medicine tank. The liquid medicine inlet pipe 6 is communicated with the liquid pump, and a plurality of liquid medicine outlet pipes are fixed at the bottom of the liquid medicine inlet pipe 6. The liquid medicine in the liquid medicine tank is pumped into the liquid medicine inlet pipe 6 by the liquid pump, and the outlet of the liquid medicine outlet pipe is located in the U-shaped groove. The concentrated discharge of the liquid medicine from the outlet of the liquid medicine outlet pipe is not conducive to the mixing of the liquid medicine and the sewage. In one specific embodiment of the present application, a liquid medicine outlet disc 13 is fixed at the bottom of the liquid medicine outlet pipe and communicated with the liquid medicine outlet disc 13. A plurality of liquid medicine outlet holes are formed in the disc body of the liquid medicine outlet disc 13. In addition, a water uniformizing plate 5 is fixed between the side walls of the hydrolysis acidification tank 1 and communicated with the inclined block 4 to form a water falling gap 501. The sewage flowing into the hydrolysis acidification tank 1 through the sewage inlet pipe 2 falls uniformly on the inclined block 4, further improving the mixing effect and efficiency between the liquid medicine and the sewage.

[0027] As shown in Fig. 3 A first rotating shaft 7 is movably connected between the side walls of the hydrolysis acidification tank 1. A plurality of water baffle plates 701 are fixed on the shaft body of the first rotating shaft 7 and located at the bottom of one side of the water outlet groove 101. When the mixed liquid of the sewage and the liquid medicine flows out through the water outlet groove 101, the mixed liquid contacts the water baffle plates 701. Under the action of the potential energy of the mixed liquid, the first rotating shaft 7 rotates, and the water baffle plates 701 disturb the mixed liquid and then flow into the tank body at the bottom of the hydrolysis acidification tank 1, further improving the mixing effect of the sewage and the liquid medicine.

[0028] In addition, in one specific embodiment of the present scheme, a second rotating shaft 8 is movably connected between the side walls of the hydrolytic acidification tank 1, a plurality of first stirring paddles 702 are fixed on the shaft body of the second rotating shaft 8, a first connecting disc and a second connecting disc are respectively fixed on the shaft bodies of the first rotating shaft 7 and the second rotating shaft 8 extending out of the hydrolytic acidification tank 1, and a first belt is connected between the first connecting disc and the second connecting disc. In this way, under the potential energy of the mixed solution, the first rotating shaft 7 rotates to drive the second connecting disc and the second rotating shaft 8 to rotate through the first belt, so as to realize the stirring of the first stirring paddles 702 to the sewage flowing into the tank body at the bottom of the hydrolytic acidification tank 1, thereby achieving energy saving and further improving the mixing effect and efficiency of the sewage and the liquid medicine.

[0029] In another specific embodiment of the present scheme, a third rotating shaft 9 is movably connected between the side walls of the hydrolytic acidification tank 1, a plurality of second stirring paddles are fixed on the shaft body of the third rotating shaft 9, a third connecting disc and a fourth connecting disc are respectively fixed on the shaft bodies of the second rotating shaft 8 and the third rotating shaft 9 extending out of the hydrolytic acidification tank 1, and a second belt is connected between the third connecting disc and the fourth connecting disc. In this way, when the second rotating shaft 8 rotates, the third rotating shaft 9 is driven to rotate through the second belt, thereby realizing further stirring of the first stirring paddles 702 and the second stirring paddles to the sewage and the liquid medicine flowing into the tank body at the bottom of the hydrolytic acidification tank 1.

[0030] As a supplement to the scheme, sewage flows into the top of the hydrolysis acidification tank 1 through the sewage inlet pipe 2, and the gap of the water falling gap 501 is transverse and narrow, so that the downward flowing sewage moves transversely along the gap, and finally flows out through the water falling gap 501, realizing the dispersed flow of the sewage. The dispersed downward flowing sewage enters the U-shaped groove formed between the L-shaped vertical plate 10 and the inclined block 4. In the initial state, the gate plate 11 blocks the water outlet groove 101, and the sewage is accumulated in the U-shaped groove. The liquid medicine in the medicine tank is pumped into the liquid medicine inlet pipe 6 by the liquid pump, and is sprayed from the medicine holes on the liquid medicine outlet disc 13, realizing the mixing of the liquid medicine and the sewage. As the amount of sewage in the U-shaped groove increases, the buoyancy ball 12 moves upward, thereby driving the gate plate 11 to move upward. The sewage is discharged through the water outlet groove 101. Since the water outlet groove 101 is arranged at the bottom of the L-shaped vertical plate 10, the sewage flowing into the bottom of the hydrolysis acidification tank 1 must pass through the liquid medicine outlet disc 13, thereby realizing the full mixing of the liquid medicine and the sewage. When the mixed liquid of the sewage and the liquid medicine flows out through the water outlet groove 101, the mixed liquid contacts the water baffle 701, and under the action of the potential energy of the mixed liquid, the first rotating shaft 7 rotates. The water baffle 701 disturbs the mixed liquid and then flows to the tank body at the bottom of the hydrolysis acidification tank 1, further improving the mixing effect of the sewage and the liquid medicine. The first belt drives the second connecting disc and the second rotating shaft 8 to rotate, the second belt drives the third rotating shaft 9 to rotate, and then the first stirring paddle 702 and the second stirring paddle further stir the sewage and the liquid medicine flowing into the tank body at the bottom of the hydrolysis acidification tank 1. This process does not consume electric energy, and the mixing of the liquid medicine and the sewage is realized when the sewage enters the hydrolysis acidification tank 1, thereby saving energy and improving the mixing efficiency and effect of the liquid medicine and the sewage.

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended embodiments and their equivalents.
