The outer cylinder body 1 is funnel-shaped, and the bottom of the outer cylinder body 1 is provided with a discharge opening 12 for discharging.

When the livestock and poultry breeding wastewater treatment device is used, the discharge port 12 is closed, breeding wastewater is added into the outer cylinder body 1 from the injection port 3, the wastewater rises along the straight cylinder 10 along with the rise of the water level, then enters the second groove 24 along the corrugated pipe 25, then enters the cavity 21 through the second groove 24, and then enters the inner cylinder body 2 from the overflow hole 20, the water level in the inner cylinder body 2 rises continuously at the moment, the rotating rod 22 and the guide plate 23 rise under the self buoyancy of the rotating rod 22 and the guide plate 23, the guide plate 23 drives the corrugated pipe 25 to extend, the top of the guide plate 23 floats on the water surface, the rotating rod 22 is positioned below the water surface, the overflow hole 20 is also positioned below the water surface, and the water injection is stopped after the proper amount of the breeding wastewater is added.

At this moment, the rotating rod 22 floats in water under the action of the guide plate 23 and the rotating rod 22, the overflow hole 20 is located under the water surface, then the motor 4 is started, the motor 4 drives the rotating rod 22 to rotate through the chute 28 on the sleeve 8, after the motor 4 drives the rotating rod 22 to rotate, the sliding rod 18 and the sliding block 30 generate a centrifugal force, at this moment, one end of the sliding rod 18, which is far away from the sliding block 30, can overcome the elastic force of the pressure spring 17 to be in contact with the inner wall of the inner barrel 2, because the inner barrel 2 is not rotating, the sliding rod 18 slides on the inner wall of the inner barrel 2, when the sliding rod 18 slides to the position of the spiral groove 6, the pressure spring 17 continues to be compressed under the action of the centrifugal force, the sliding rod 18 is clamped in the spiral groove 6 and rotates downwards along the direction of the spiral groove 6, and finally slides into the annular groove 19 along the spiral groove 6, at this moment, the sliding rod 18 is located at the bottom of the inner barrel 2, and the scraper 26 is in contact with the inner bottom wall of the inner barrel 2.

When the sleeve 8 rotates, the sleeve 8 drives the rotating shaft 15 to rotate through the connecting plate 27, the rotating shaft 15 drives the spiral sheet 9 to rotate, the spiral sheet 9 rotates relative to the straight cylinder 10, at the moment, the liquid level in the outer cylinder 1 is higher than that in the inner cylinder 2, therefore, when the spiral sheet 9 rotates, the effect of a spiral water pump is generated, water is continuously pumped into the straight cylinder 10 from the first groove 11, then the water enters the second groove 24 from the straight cylinder 10, then the water is discharged into the inner cylinder 2 from the cavity 21 through the overflow hole 20 by the second groove 24, at the moment, the height of the wastewater in the outer cylinder 1 and the inner cylinder 2 forms a fall, the wastewater in the inner cylinder 2 is discharged from the water squeezing hole 7 in a parabolic shape and falls into the outer cylinder 1 again, when the motor 4 is started, oxygen is introduced into the air passage 16 through the aeration pipe 14, the oxygen is discharged into the outer cylinder 1 and the inner cylinder 2 from the one-way valve on the air passage 16, when the oxygen enters the cavity 21 along with water flow, the water is discharged from the parabolic shape, the air is discharged from the rotating rod 22, the oxygen is added into the small oxygen dispersing hole, and is uniformly filled into the small overflow hole 2, and the small cylinder 1, the small cylinder 2, and the oxygen is uniformly filled into the small cylinder 1, and the small cylinder 2.

After oxygen is filled, activated sludge is generated in the wastewater, the scraper 26 is driven to rotate by the rotating rod 22, the scraper 26 pushes the sludge deposited at the bottom of the inner cylinder 2 to the upper part of the rotating rod 22 through an inclined plane, the sludge is driven to roll by water flow and gas sprayed from the overflow holes 20, so that the sludge is in a suspended state and is fully contacted with the wastewater, after aeration is finished, the motor 4 stops rotating, oxygen in the aeration pipe 14 stops being supplied, the slide block 30 and the slide rod 18 are not under the action of centrifugal force and slide in the cavity 21 under the action of the pressure spring 17, the slide rod 18 is separated from the annular groove 19, the rotating rod 22 and the guide plate 23 rise upwards under the buoyancy of the water and pull the corrugated pipe 25 to extend, the overflow holes 20 are always positioned below the water surface of the wastewater in the inner cylinder 2, then stand for waiting for the precipitation of the activated sludge, after the precipitation is finished, the discharge port 12 is opened, the precipitate in the outer cylinder 1 is discharged, the wastewater in the inner cylinder 2 flows into the corrugated pipe 25 through the overflow holes 20, the outer cylinder 10, the sludge in the outer cylinder 1 is discharged, and the sludge in the inner cylinder 2 is discharged, and the inner cylinder 2, when the aeration rod 22 is discharged, the wastewater, the inner cylinder 2 is discharged, and the sludge in the outer cylinder 2, the inner cylinder 2, the aeration efficiency is shortened.

In conclusion, this beasts and birds cultivation effluent treatment plant, through the setting of outer barrel 1 and interior barrel 2, make the waste water that treats divide into two parts, can carry out secondary treatment, through the cooperation setting of bellows 25 and baffle 23, cut apart interior barrel 2 and straight section of thick bamboo 10, through the cooperation setting of baffle 23 and sleeve 8, the mud in interior barrel 2 can not discharge, the time that the aeration next time used has been reduced, increase waste water treatment efficiency, through bull stick 22 and baffle 23, the cooperation setting of bull stick 22 and scraper blade 26, can stir the mud of bottom in the interior barrel 2, set up overflow hole 20, when stirring mud, cause ascending impact force to mud, make mud suspend in the waste water in interior barrel 2, make mud and waste water contact more abundant, the treatment effect is better.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
