[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5As shown, in this embodiment, a low-viscosity denitrification liquid production and processing equipment includes a support frame 1, the upper end of the support frame 1 is fixedly connected to a mixing drum 2, the upper end of the mixing drum 2 is provided with a liquid guide port 4 and a discharge port 5, the discharge port 5 is provided with a sealing door 13, the bottom of the mixing drum 2 is provided with a discharge port 7, the inside of the discharge port 7 is provided with a valve 14, the inside of the mixing drum 2 is rotatably connected to a rotating shaft 8, one end of the rotating shaft 8 is connected to a driving mechanism, the outer side of the rotating shaft 8 is provided with a stirring assembly, and the stirring assembly is composed of a first stirring blade 9, a second stirring blade 10 and a third stirring blade 11. The first stirring blade 9, the second stirring blade 10 and the third stirring blade 11 are composed of two stirring blades, and all of them are spiral blade structures. The first stirring blade 9, the second stirring blade 10 and the third stirring blade 11 are all surrounded by the outer surface of the rotating shaft 8 and are distributed in sequence with equal intervals from the inside to the outside along the radial direction of the rotating shaft 8. The intersection positions of the first stirring blade 9, the second stirring blade 10 and the third stirring blade 11 are all provided with connecting rods 12 and are fixedly connected to the connecting rods 12, and one end of the connecting rod 12 is fixedly connected to the side wall of the rotating shaft 8.

[0022] Among them, the driving mechanism consists of a driving motor 3 and a mounting plate 6. The bottom of the driving motor 3 is fixedly connected to the mounting plate 6, the mounting plate 6 is fixedly connected to the upper end of the support frame 1, and the end of the output shaft of the driving motor 3 is fixedly connected to the shaft end of the rotating shaft 8.

[0023] The rotating shaft 8 can be driven to rotate by the driving motor 3, thereby driving the stirring assembly to stir the denitrification liquid and limestone.

[0024] The widths of the first stirring blade 9 , the second stirring blade 10 and the third stirring blade 11 are all less than three centimeters.

[0025] This arrangement can prevent the stirring blade from being too wide and causing the stirring blade to encounter too much resistance during rotation.

[0026] The connecting rods 12 are respectively arranged along the radial direction of the rotating shaft 8 , and the plurality of connecting rods 12 are distributed in a cross shape in a lateral view.

[0027] Such an arrangement can make the overall structure of the stirring component tend to be balanced, making the stirring component more stable when rotating.

[0028] The utility model provides a low-viscosity denitrification liquid production and processing equipment, the specific working principle is as follows:

[0029] When in use, the denitrification liquid is introduced into the mixing drum 2 through the liquid guide port 4, and the crushed limestone is put into the mixing drum 2 through the discharge port 5. The discharge port 5 can be sealed by the sealing door 13, and the liquid guide port 4 is usually connected to the connecting pipe of the feed, and there is no leakage. Then the driving motor 3 is started to drive the rotating shaft 8 to rotate, and then drive the stirring component to rotate to stir the denitrification liquid. The number of the No. 1 stirring blade 9, the No. 2 stirring blade 10 and the No. 3 stirring blade 11 in the stirring component are all spiral blade structures. In the limited space of the mixing drum 2, the structure of the spiral blade is compared with the traditional straight rod structure, which can make the stirring blade able to stir a larger liquid area during stirring, make the mixing between the denitrification liquid and the limestone more intense, and more effectively improve the stirring effect and efficiency. At the same time, the No. 1 stirring blade 9, the No. 2 stirring blade 10 and the No. 3 stirring blade 11 are distributed in equal intervals from the inside to the outside along the radial direction of the rotating shaft 8, so that the stirring blade can stir the denitrification liquid at multiple levels, further improving the stirring efficiency.
