Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a mixing and flocculation reaction device with an extended reaction time. Background Technology

[0002] Flocculants are used in the sludge treatment industry to flocculate fine sludge particles into larger flocs. Larger and faster floc formation significantly benefits subsequent sludge dewatering. Therefore, a flocculation reaction device is needed to mix the wastewater and flocculant. However, existing devices, designed to maximize reaction time, are generally large and cannot be installed in certain specialized environments. Conversely, smaller devices often have limited internal piping space, resulting in shorter reaction times. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a mixing and flocculation reaction device that can extend the reaction time.

[0004] The technical solution of this utility model is as follows: a mixing flocculation reaction device with extended time, comprising multiple interconnected columnar shells, wherein the columnar shells are provided with a first spiral channel and a second spiral channel distributed vertically, the multiple first spiral channels and the multiple second spiral channels are respectively connected end to end in the multiple columnar shells, thereby forming two intertwined and independent spiral channels, and the first spiral channel and the second spiral channel at the bottom are interconnected.

[0005] Preferably, the first spiral channel at the top has an inlet located outside the cylindrical shell, the second spiral channel at the top has a drain outlet, and a check valve is installed at the connection between the first spiral channel and the second spiral channel.

[0006] Preferably, all of the first spiral channels are fixed and connected to infusion tubes, and the multiple infusion tubes are connected to the same dispensing tube.

[0007] Preferably, the stirring device is fixed inside the first spiral channel.

[0008] Preferably, the stirring device includes a mounting frame, in which a stirring shaft is rotatably mounted, and blades are mounted on the stirring shaft.

[0009] Compared with existing technologies, the beneficial effects of this utility model are: by forming two intertwined and independent spiral channels inside the columnar shell, a longer reaction space is formed in a smaller space, thereby extending the mixing time. The mixing time is extended by allowing the sewage and flocculant to move repeatedly within the two spiral channels. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] See attached document Figure 1-4 A time-extending mixing and flocculation reaction device includes multiple interconnected columnar shells 1. Each columnar shell 1 has a first spiral channel 2 and a second spiral channel 3 distributed vertically. The multiple first spiral channels 2 and multiple second spiral channels 3 are connected end to end within the multiple columnar shells 1, thereby forming two intertwined and independent spiral channels. The first spiral channels 2 and the second spiral channels 3 at the bottom are interconnected. This arrangement creates a longer reaction space within a smaller space, thereby extending the mixing time. The extended mixing time is achieved by the repeated movement of wastewater and flocculant within the two spiral channels.

[0017] Specifically, the first spiral channel 2 at the top has an inlet 8 located outside the cylindrical shell 1, and the second spiral channel 3 at the top has a drain outlet 9. A check valve 7 is installed at the connection between the first spiral channel 2 and the second spiral channel 3. Sewage can be input into the cylindrical shell 1 through the inlet 8. The sewage enters the first spiral channel 2 and then flows continuously to the bottom of the cylindrical shell 1 through the spiral water channel formed by multiple first spiral channels 2. Finally, because the first spiral channel 2 and the second spiral channel 3 at the bottom are connected, the sewage flows into the second spiral channel 3. The check valve 7 at this point prevents sewage backflow. At this time, sewage continues to be input at the inlet 8. Under the action of pressure, the sewage in the second spiral channel 3 rises continuously in the spiral water channel formed by multiple second spiral channels 3. This spiral descent and spiral ascent in a small space prolongs the mixing time. Finally, when the sewage flows to the top of the spiral water channel formed by multiple second spiral channels 3, it will be discharged through the drain outlet 9.

[0018] It should be noted that in this embodiment, multiple first spiral channels 2 are fixed and connected to infusion pipes 5, and multiple infusion pipes 5 are connected to the same delivery pipe 6. This allows flocculant to be injected in sections as the sewage continuously descends in the spiral waterway formed by multiple first spiral channels 2. The flocculant can react better with the sewage. When in use, flocculant can be injected into the delivery pipe 6.

[0019] It should also be noted that a stirring device 4 is fixed inside the first spiral channel 2. The stirring device 4 includes a mounting frame 41, and a stirring shaft 42 is rotatably mounted inside the mounting frame 41. Blades 43 are mounted on the stirring shaft 42. During operation, when the sewage moves in the spiral waterway formed by the multiple first spiral channels 2, because the sewage has kinetic potential energy, when it passes through the stirring device 4, it will push the blades 43 to make the stirring shaft 42 rotate. This setting can achieve the effect of stirring the sewage and flocculant, thereby making the reaction effect better.
