[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figures 1 to 5 , an equipment for improving the acid production efficiency of wastewater hydrolysis and acidification, including a hydrolysis and acidification tank 1, the bottom of the hydrolysis and acidification tank 1 is embedded with a sewage outlet 2, the sewage outlet 2 is used to discharge sewage or sludge for recycling.

[0028] Two threaded rods 13 are rotatably mounted inside the hydrolysis acidification tank 1 , and nut pairs 14 are fixedly mounted on the two threaded rods 13 , and mounting plates 8 are fixedly mounted on the two nut pairs 14 .

[0029] When the two threaded rods 13 are rotated synchronously, the two nut pairs 14 will translate synchronously, thereby driving the mounting plate 8 to move stably.

[0030] A hollow chamber 6 is fixedly mounted on the mounting plate 8, and a water pipe 7 is embedded in the hollow chamber 6;

[0031] Drainage outlets 9 are fixedly installed at the bottom of the hollow chamber 6 at equal intervals;

[0032] The sewage to be hydrolyzed and acidified is discharged into the hollow chamber 6 through the water pipe 7 and then can be evenly discharged through the drain port 9 .

[0033] The hydrolysis acidification tank 1 is inlaid with a filter plate 5. It is worth noting that the highest water level should not exceed the lowest point of the filter plate 5.

[0034] The sewage discharged from the drain port 9 will fall onto the filter plate 5, and the filter plate 5 can intercept the impurities, suspended matter and other substances that are difficult to decompose in the sewage, thereby ensuring the effect of hydrolysis and acidification.

[0035] Moreover, the mounting plate 8 is constantly moving, so the falling position of the sewage is also constantly changing. On the one hand, the sewage can be brought into contact with the filter plates 5 at different positions, thus avoiding the filter plates 5 from having a constant contact position and being easily blocked. On the other hand, the sewage can be combined with the sludge at different positions of the hydrolysis and acidification tank 1, thereby further improving the efficiency of the hydrolysis and acidification.

[0036] A mounting frame 19 is fixedly mounted on the mounting plate 8, and a brush plate 17 is fixedly mounted on the mounting frame 19. The brush plate 17 can contact the filter plate 5;

[0037] When the mounting plate 8 moves, since the brush plate 17 is in direct contact with the filter plate 5, the brush plate 17 can clean the impurities on the filter plate 5, push the impurities on the filter plate 5, and move them to both sides of the filter plate 5, thereby cleaning the filter plate 5 in real time and further ensuring the continuity of the equipment operation.

[0038] A driving motor 3 is provided on the hydrolysis acidification tank 1 . The output end of the shaft of the driving motor 3 is fixedly connected to one of the threaded rods 13 . The two threaded rods 13 are connected by a synchronous belt 4 .

[0039] When the driving motor 3 is started, the threaded rod 13 connected thereto can be rotated. The rotation of the threaded rod 13 is transmitted through the synchronous belt 4, so that the two threaded rods 13 rotate synchronously.

[0040] The cross section of the filter plate 5 is in the shape of a Chinese character "F", with the filter plate 5 being higher in the middle and lower on both sides. The threaded rod 13 is in direct contact with the higher portion of the filter plate 5 .

[0041] The brush plate 17 can move the impurities to both sides of the filter plate 5, that is, the impurities fall on the lower ends of the filter plate 5 for collection and processing. Manual subsequent cleaning only requires cleaning both sides, which has low labor intensity and higher efficiency.

[0042] A connecting plate 10 is fixedly mounted between the two mounting plates 8 , a rotating shaft 11 is rotatably mounted on the connecting plate 10 , and stirring paddles 12 are fixedly mounted at equal distances on one end of the rotating shaft 11 away from the connecting plate 10 .

[0043] When the rotating shaft 11 is rotated, the stirring paddle 12 can stir the sludge at the bottom of the hydrolysis acidification tank 1, thereby dispersing the sludge, increasing the contact area between the sludge and the sewage to be treated, and improving the acid production efficiency.

[0044] Mounting bars 15 are fixedly mounted on both sides of the hydrolysis acidification tank 1 , racks 16 are fixedly mounted on the mounting bars 15 , and gears 18 are fixedly mounted at corresponding positions on the rotating shafts 11 on both sides, and the gears 18 are in meshing relationship with the corresponding racks 16 .

[0045] When the mounting plate 8 moves, the connecting plate 10 will move synchronously, and then the rack 16 and the gear 18 will move relative to each other. Driven by the meshing relationship, the rack 16 will rotate, and then the rotating shaft 11 will drive the stirring paddle 12 to rotate, thereby achieving the effect of stirring the sludge in various parts of the hydrolysis acidification tank 1. No external power source is required, which saves energy and can improve the acid production effect.

[0046] The rotating shaft 11 at the center is connected to the rotating shaft 11 on one side via a transmission belt 20 .

[0047] When the rotating shaft 11 on one side rotates, the rotating shaft 11 at the center position rotates synchronously through the transmission belt 20, and then the three rotating shafts 11 can rotate together, ensuring that the sludge in each part inside can be fully dispersed.

[0048] The working process of the present invention is as follows: the sewage to be hydrolyzed and acidified is discharged into the hollow chamber 6 through the water pipe 7, and then the sewage is discharged through the uniform drain port 9. The driving motor 3 is started, and through transmission, the two threaded rods 13 rotate synchronously, and the nut pair 14 translates synchronously, thereby driving the mounting plate 8 to move stably, and the falling position of the sewage is constantly changing. On the one hand, the sewage can be brought into contact with the filter plates 5 at different positions to avoid the filter plates 5 having a constant contact position and easy clogging. On the other hand, the sewage can be combined with the sludge at different positions of the hydrolysis and acidification tank 1, thereby further improving the efficiency of hydrolysis and acidification.

[0049] When the mounting plate 8 is moved, since the brush plate 17 is in direct contact with the filter plate 5, the brush plate 17 can clean the impurities on the filter plate 5. The brush plate 17 can move the impurities to both sides of the filter plate 5, that is, the impurities fall on the lower ends of the filter plate 5 for collection and processing. Manual subsequent cleaning only requires cleaning both sides, which has low labor intensity and higher efficiency.

[0050] When the mounting plate 8 moves, the rack 16 and the gear 18 will move relative to each other. Driven by the meshing relationship, the rack 16 will rotate, and then the rotating shaft 11 will drive the stirring paddle 12 to rotate, thereby achieving the effect of stirring the sludge in various parts of the hydrolysis and acidification tank 1, so that the sludge is dispersed, and the contact area between the sludge and the sewage to be treated is increased, which can improve the acid production efficiency in the hydrolysis and acidification.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
