[0024] The embodiment of the utility model provides a sewage treatment agent polymerization reaction device.

[0025] See also Figures 1 to 4, comprising a tank body 1, a stirring chamber 15 is arranged in the tank body 1, a vertical rotating tube 8 and an internally threaded tube 11 are rotatably connected to the upper part of the tank body 1, the internally threaded tube 11 is located directly below the vertical rotating tube 8, a vertical shaft rod 13 is slidably connected in a limiting slide groove provided at the bottom end of the vertical rotating tube 8, a stirring rod 14 distributed in a circumferential array is fixedly connected to the bottom end of the vertical shaft rod 13, the stirring rod 14 is located inside the stirring chamber 15, an externally threaded tube 10 is rotatably sleeved on the outer side of the vertical shaft rod 13, the internally threaded tube 11 is threadedly sleeved on the outer side of the externally threaded tube 10, and a rotating driving mechanism 9 for driving the internally threaded tube 11 to reciprocate is arranged on the tank body 1;

[0026] The sewage and the sewage treatment agent are simultaneously placed in the stirring chamber 15 for polymerization reaction. At the same time, by rotating the vertical rotating tube 8, the vertical rotating tube 8 drives the stirring rod 14 to rotate through the vertical shaft 13, and the stirring rod 14 stirs the sewage. The vertical shaft 13 also rotates on the external threaded tube 10.

[0027] When the height of the stirring rod 14 needs to be adjusted, the internal threaded tube 11 can be rotated, and the internal threaded tube 11 drives the external threaded tube 10 to rise and fall in the tank body 1, and the external threaded tube 10 drives the stirring rod 14 on the vertical shaft 13 to rise and fall together.

[0028] Please refer again Figure 4 The rotation driving mechanism 9 includes a rotating disk 901, a half gear 903, and a spur gear 904. The rotating disk 901 and the half gear 903 are fixedly sleeved on the outer side of the vertical rotating tube 8. The spur gear 904 is rotatably connected to the tank body 1. An annular groove 902 is provided at the bottom of the rotating disk 901. The spur gear 904 is located in the cavity of the annular groove 902. A meshing gear group is provided on one side of the half gear 903 and the inner wall of one side of the annular groove 902. The two meshing gear groups are respectively located on both sides of the vertical rotating tube 8, and the two meshing gear groups are meshed and connected with the spur gear 904.

[0029] When the vertical rotating tube 8 rotates, it will drive the rotating disk 901 and the half gear 903 to rotate together. When the meshing gear group of the annular groove 902 on the rotating disk 901 is engaged with the spur gear 904, the meshing gear group on the spur gear 904 and the half gear 903 do not contact each other. The meshing gear group on the annular groove 902 will drive the spur gear 904 to rotate forward until the meshing gear group on the spur gear 904 and the half gear 903 are engaged. At this time, the spur gear 904 and the meshing gear group on the annular groove 902 do not contact each other, and the meshing gear group on the half gear 903 will drive the spur gear 904 to rotate reversely. This cycle allows the spur gear 904 to rotate back and forth.

[0030] Please refer again Figure 1 and Figure 4The bottom of the spur gear 904 is fixedly connected with a fixing rod 17, the bottom end of the fixing rod 17 is fixedly connected with a speed limiting gear 18, the speed limiting gear 18 is rotatably connected to the tank body 1, and the outer side of the internal threaded tube 11 is fixedly sleeved with a speed limiting gear ring 12 meshing with the speed limiting gear 18;

[0032] The speed limiting gear 18 has a diameter smaller than that of the speed limiting gear ring 12 , thereby reducing the rotation speed of the speed limiting gear ring 12 and preventing the stirring rod 14 from rising or falling too quickly.

[0033] Please refer again Figures 1 to 4 , the inner wall of the limiting slide groove is fixedly connected with first wire rods distributed in a circumferential array, and the vertical shaft rod 13 is provided with a first wire groove at a corresponding position relative to each first wire rod, and each first wire groove is slidably connected to each first wire rod;

[0034] The sliding connection between the first wire groove and the first wire rod can ensure that the vertical shaft rod 13 can only slide in the limiting sliding groove but cannot rotate.

The externally threaded tube 10 is provided with a second wire groove at a corresponding position relative to each second wire rod, and each second wire groove is slidably connected to each second wire rod respectively;

[0036] The sliding connection between the second wire groove and the second wire rod can ensure that the external threaded pipe 10 can only slide in the stable groove but cannot rotate.

[0037] Please refer again Figure 2 A mixing box 6 is provided on one side of the tank body 1, and a spray plate 19 and a conical barrel 20 are suspended inside the mixing box 6.

The liquid inlet 5 is connected to the spray plate 19 through a first conduit, and the sewage inlet 7 is connected to the top of the conical barrel 20 through a second conduit;

[0038] The sewage inlet 7 is connected to the sewage source, and the sewage is discharged to the top of the conical barrel 20 by using the sewage inlet 7. The sewage flows downward along the outer inclined surface of the conical barrel 20, so that the sewage can be spread out and the thickness or depth of the sewage flow can be reduced. The liquid inlet 5 is connected to the sewage treatment agent water source. The sewage treatment agent can be transported to the spray plate 19 by using the liquid inlet 5. A plurality of nozzles are arranged at the bottom of the spray plate 19. The sewage treatment agent is sprayed by the nozzles, and the sewage treatment agent is evenly sprinkled on the upper surface of the conical barrel 20, thereby increasing the contact area between the sewage and the sewage treatment agent, thereby achieving the effect of sufficient mixing and contact with each other.

[0039] Please refer again Figure 2 A connecting assembly 3 is connected between the mixing box 6 and the tank body 1, and the connecting assembly 3 includes a water pump, a water outlet pipe and a water inlet pipe.
