[0001] This utility model relates to the field of water treatment technology, and in particular to a polyacrylamide uniform spraying device for sedimentation tanks. Background Technology

[0002] Polyacrylamide (PAM) is a synthetic organic polymer that has a strong adsorption effect on solid surfaces in water. It forms bridges between particles, causing fine and loose flocs to become large and dense, thus accelerating the formation of sediment.

[0003] Polyacrylamide is a bagged powdered solid. Powdered PAM is poured into a mixing tank, a certain amount of water is added, and it is dissolved, mixed, and stirred. After dissolving, it is poured into the dosing tank. This dosing and mixing is insufficient, which affects the concentration of the agent and thus affects the effect of removing suspended solids from the water. Utility Model Content

[0024] The addition component 6 includes a water pump 11 installed on the outer wall of the top of the mixing cylinder 1, a water pumping pipe 12 connected to the input end of the water pump 11, and a filter 13 installed at the other end of the water pumping pipe 12, and the output end of the water pump 11 is connected to the inside of the mixing cylinder 1.

[0025] The water pump 11, the material turning motor 16, and the stirring motor 10 are connected to a switch via wires, and the switch is connected to a power source via wires.

[0026] The water pump 11 is started to draw water through the water pipe 12 and add it to the mixing drum 1. The liquid level window and scale line make it easy to judge the amount of water added.

[0027] The stirring motor 10 drives the main shaft 7 in the stabilizer 9 to rotate, and the stirring frame 8 on the main shaft 7 mixes and stirs the particles and water to accelerate the fusion speed.

[0028] The stirring rack 8 on the outer wall of the main shaft 7 disturbs the water during rotation, accelerating the mixing speed, while the stabilizing seat 9 ensures the stability of the main shaft 7 during rotation.

[0029] The filter 13 at one end of the water pumping pipe 12 contains filter media, which intercepts the water pumped in during the water pumping process to prevent foreign objects from entering and causing damage to the water pump.

[0030] Example 2:

[0031] Reference Figure 1-4 As shown, the stirring assembly 5 includes a main shaft 7 rotatably connected to the center of the mixing cylinder 1, a stirring frame 8 installed on the outer wall of the bottom end of the main shaft 7, and a stabilizing seat 9 installed at the center of the inner wall of the bottom of the mixing cylinder 1.

[0032] The bottom end of the main shaft 7 is rotatably connected to the stabilizing seat 9, and a stirring motor 10 is installed on the outer wall of the top end of the mixing cylinder 1. The output shaft of the stirring motor 10 is connected to the top end of the main shaft 7, and the outer wall of the stabilizing seat 9 is provided with equally spaced notches.

[0033] The batching assembly 2 includes a tipping hopper 14 installed at the feed inlet of the mixing cylinder 1, a rotating shaft 15 rotatably connected to the center of the top of the inner wall of the tipping hopper 14, an extension rod 17 installed at the center of the rotating shaft 15, and a tipping plate 18 installed at the other end of the extension rod 17.
