[0023] The following combines the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0024] Please refer to Figures 1 to 2 As shown, an even water distribution device for the inlet of an acidification tank is connected to the main inlet pipe 2 and is used to evenly distribute sewage into the acidification tank 1. It includes a plurality of horizontal water distribution pipes 3, and the plurality of horizontal water distribution pipes 3 are fixedly arranged at intervals on the top surface of the acidification tank 1 (in the prior art, the top surface of the acidification tank 1 is a cement surface). One end of each horizontal water distribution pipe 3 is respectively connected to the main inlet pipe 2, and a plurality of vertical water distribution pipes 4 are connected and communicated on one side of each horizontal water distribution pipe 3. The top end of each vertical water distribution pipe 4 is detachably connected to and communicated with the corresponding horizontal water distribution pipe 3, and each vertical water distribution pipe 4 respectively passes through the top surface of the acidification tank 1 and extends into the interior of the acidification tank 1. In this embodiment, the bottom end of the vertical water distribution pipe 4 is 20 to 30 centimeters away from the bottom surface of the acidification tank 1, preferably 20 centimeters, to meet the water distribution requirements.

[0025] During implementation, the sewage in the main inlet pipe 2 passes through a plurality of horizontal water distribution pipes 3 and a plurality of vertical water distribution pipes 4 in sequence and is evenly distributed into the acidification tank 1. By arranging the even water distribution device for the inlet of the acidification tank at the top end of the acidification tank 1 and setting the horizontal water distribution pipes 3 and the vertical water distribution pipes 4 to be detachably connected, it is convenient for timely cleaning and maintenance. When the horizontal water distribution pipe 3 is blocked, the staff can clean the horizontal water distribution pipe 3 separately. Specifically, a blind plate 32 is detachably connected to the end of the horizontal water distribution pipe 3 away from the main inlet pipe 2. When the horizontal water distribution pipe 3 is blocked, the horizontal water distribution pipe 3 can be dredged by removing the blind plate 32. Preferably, a hand-operated filter (not shown in the figure) is connected and communicated at one end of each horizontal water distribution pipe 3 close to the main inlet pipe 2. The hand-operated filter is a prior art. When the filter is blocked, it is not necessary to frequently disassemble the filter screen. The filter screen can be cleaned directly by shaking the handle, which is convenient and fast, and will not be elaborated here.

[0026] When the water distribution vertical pipe 4 is blocked, the blocked water distribution vertical pipe 4 and the water distribution horizontal pipe 3 can be disassembled and cleaned. Avoid the problem of blockage, which will cause the water inlet capacity of the acidification tank 1 to fail to meet the design requirements, and the wastewater discharged from production cannot be treated in time, affecting the company's production. Figure 3 As shown, in this embodiment, a plurality of first flanges 31 are fixedly provided on one side of the water distribution horizontal pipe 3, and a second flange 41 matched with the first flange 31 is fixedly provided on the top of the water distribution vertical pipe 4. During implementation, the first flange 31 and the second flange 41 are fixed to each other by bolts and nuts, thereby realizing a detachable connection between the water distribution horizontal pipe 3 and the water distribution vertical pipe 4.

[0027] See also Figure 4 As shown, in this embodiment, the outer sides of the first flange 31 and the second flange 41 are clamped with a clamping ring 5 to facilitate the staff to quickly disassemble the water distribution horizontal pipe 3 and the water distribution vertical pipe 4. Among them, the clamping ring 5 includes an upper fixing ring 51 and a lower fixing ring 52 arranged opposite to each other. The upper fixing ring 51 and the lower fixing ring 52 are both semi-circular in shape to adapt to the circular first flange 31 and the second flange 41. One end of the upper fixing ring 51 and the lower fixing ring 52 are hinged to each other through a connecting member. In this embodiment, the connecting member is two arc plates 56. The top ends of the two arc plates 56 are respectively rotatably connected to the two sides of the width direction of the upper fixing ring 51, and the bottom ends of the two arc plates 56 are respectively rotatably connected to the two sides of the width direction of the lower fixing ring 52. The upper fixing ring 51 and the lower fixing ring 52 are hinged by setting the arc plates 56 to further adapt to the circular first flange 31 and the second flange 41.

[0028] The end of the lower fixing ring 52 away from the connecting piece is rotatably connected to the locking rod 53, and the end of the upper fixing ring 51 away from the connecting piece is provided with a clearance opening 54 for accommodating the locking rod 53. A butterfly nut 55 is threaded on the locking rod 53, and the outer diameter of the butterfly nut 55 is larger than the width of the clearance opening 54. The opposing surfaces of the upper fixing ring 51 and the lower fixing ring 52 are the inner surfaces, and the inner surfaces of the upper fixing ring 51 and the lower fixing ring 52 are respectively provided with grooves 57 for accommodating the first flange 31 and the second flange 41 after docking.

[0029] During implementation, the staff sleeved the upper fixing ring 51 and the lower fixing ring 52 on the outer sides of the first flange 31 and the second flange 41, then rotated the locking rod 53 to move it towards the relief opening 54 until the free end of the locking rod 53 was inside the relief opening 54, and then rotated the wing nut 55 to lock the upper fixing ring 51 and the lower fixing ring 52. At this time, the first flange 31 and the second flange 41 were located in the groove 57 of the upper fixing ring 51 and the lower fixing ring 52. Preferably, inclined cut surfaces 571 were symmetrically arranged between the bottom surface and the two inner side walls of the groove 57 respectively. The two inclined cut surfaces 571 extended obliquely towards the center in the width direction of the bottom surface of the groove 57 from the two side walls of the groove 57 respectively. So that during the process of tightening the wing nut 55, the first flange 31 and the second flange 41 move towards each other under the extrusion of the two inclined cut surfaces 571, and thus the fixation between the first flange 31 and the second flange 41 becomes tighter.

[0030] When the utility model is specifically implemented, the sewage in the water inlet main pipe 2 passes through a plurality of water distribution cross pipes 3 and a plurality of water distribution vertical pipes 4 in sequence and is evenly distributed into the acidification tank 1. When an individual water distribution cross pipe 3 is blocked, the water distribution cross pipe 3 can be dredged by removing the blind plate 32. When the water distribution vertical pipe 4 is blocked, the blocked water distribution vertical pipe 4 is separated from the water distribution cross pipe 3, and then it can be dredged separately. Specifically, by rotating the wing nut 55, the wing nut 55 will move towards the free end direction of the locking rod 53, and then rotate the locking rod 53 to make the locking rod 53 disengage from the relief groove. At this time, the upper fixing ring 51 and the lower fixing ring 52 can be separated, and the blocked water distribution vertical pipe 4 can be removed for cleaning.

[0031] The above description content is only the preferred embodiment of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
