Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to an air flotation machine for sewage treatment. Background Art

[0002] The flotation machine is a water treatment equipment that uses a dissolved air system to generate a large number of tiny bubbles in the water, causing the air to attach to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The buoyancy principle is used to make the air float on the water surface, thereby achieving solid-liquid separation.

[0003] Existing flotation machines, such as the utility model patent for a flotation machine for sewage treatment with patent application number CN202022362759.8, first discharge the floccules floating on the water surface after use, and finally discharge the water after solid-liquid separation. The discharged water also needs to be filtered through a filter plate to prevent impurities from being discharged with the liquid. However, this method is very likely to cause the filter plate to be blocked, affecting the discharge of water, and there are certain shortcomings.

[0004] Therefore, an air flotation machine for sewage treatment is provided to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-4 A flotation machine for sewage treatment includes a main body 1, on which a liquid inlet 101 and a liquid outlet pipe 103 are provided, and also includes: a motor 3 405, which is fixedly connected to the main body 1; a telescopic rod 404, which is fixedly connected to the output end of the motor 3 405; a filter tube 401, which is sleeved on the liquid outlet end of the liquid outlet pipe 103, and the filter tube 401 is provided with filter holes; a gear part 1 402, which is fixedly connected to the filter tube 401, and protrusions are provided on both sides of the gear part 1 402; a gear part 2 403, which is meshedly connected to the gear part 1 402, and the protrusions are used to resist the two sides of the gear part 1 402, and the gear part 2 403 is fixedly connected to the telescopic end of the telescopic rod 404.

[0028] After the suspended particles are discharged, the liquid outlet pipe 103 can be opened to discharge the water inside the body 1 through the liquid outlet pipe 103. At this time, the discharged water will be filtered through the filter tube 401, and the larger debris will be intercepted by the filter holes on the filter tube 401 and remain in the filter tube 401. At this time, the motor 3 405 can be started, and the gear part 2 403 is rotated by the rotation of the motor 3 405, so that the filter tube 401 is rotated under the meshing cooperation of the gear part 2 403 and the gear part 1 402. The rotation at this time will cause some debris to rotate accordingly, reducing the possibility of the filter holes being blocked. At the same time, the telescopic rod 404 can be started, and the telescopic rod 404 is continuously extended and retracted to make the filter tube 401 continuously move, but not separate from the external tube 3, and parts are always attached together. Since the filter tube 401 is installed in a sleeve connection, the fit between them is relatively tight. At this time, the debris in the filter tube 401 will be scratched and cleaned by the external tube 3, further reducing the possibility of the filter tube 401 being blocked.

[0029] After using for a period of time, the external tube 3 can be disassembled by rotating it, and then the impurities remaining in the filter tube 401 can be discharged, which is convenient for long-term use.

When in use, water to be treated is injected through the liquid inlet 101, and then the air pipe 201 is connected to an external air pump, the air pump is started, and gas is injected so that the gas continuously enters the air pipe 201 and is then discharged through the air outlet 202 to form smaller bubbles that come into contact with the water inside the body 1. Then, by starting the motor 104, the stirring shaft 105 is rotated to stir the sewage, so that the bubbles can fully come into contact with the suspended particles inside the sewage, causing the suspended particles to flocculate, and the flocs float on the sewage surface inside the body 1 until the solid-liquid separation is completed. The liquid outlet pipe 103 is threadedly connected to an external pipe 3, and the filter tube 401 is sleeved on the external pipe 3.

[0033] After the solid-liquid separation is completed, the motor 106 can be started to rotate the propeller 107. Through the rotation of the propeller 107, the suspended particles floating on the sewage surface are flocculated and taken away by the propeller 107, and the flocculation pipe 102 is opened to discharge the suspended particles through the flocculation pipe 102. Finally, the water after solid-liquid separation is discharged through the liquid outlet pipe 103.
