DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Embodiment: Please refer to Figures 1-3. The utility model provides a technical solution: a floating sludge collection device for a sewage treatment pool, including a treatment pool 1, a plurality of pillars 2 are arranged at the bottom of the treatment pool 1, a filter disc 4 is movably arranged at the bottom of the inner cavity of the treatment pool 1, a plurality of filter holes 5 are penetrated through the top of the filter disc 4, and an air bag 6 is also arranged at the bottom of the filter disc 4.

Among them, the filter disc 4 is made of stainless steel or other corrosion-resistant materials. The bottom of the outer ring of the treatment tank 1 penetrates the outer wall of the treatment tank 1 and is provided with a water outlet hole 3. The outer ring of the filter disc 4 is in contact with the inner wall of the treatment tank 1, and the outer ring of the filter disc 4 is provided with rubber material.

In this embodiment, when in use, the filter disc 4 is first placed in the inner cavity of the treatment tank 1. At this time, the air bag 6 is located between the bottom of the inner cavity of the treatment tank 1 and the filter disc 4. Then, the sewage can be discharged into the treatment tank 1. At this time, the sewage gathers at the top of the filter disc 4 and penetrates into the bottom of the inner cavity of the treatment tank 1 through the filter holes 5. Then, the impurities in the sewage are retained above the filter disc 4 by the filter holes 5, thereby separating the sewage from the impurities. Subsequently, after continuous infiltration of sewage, the air bag 6 will be lifted by the sewage and drive the filter disc 4 to gradually move upward in the inner cavity of the treatment tank 1 until the sewage accumulated in the treatment tank 1 reaches a certain amount. Then, the filter disc 4 can be taken out and cleaned, which is more convenient to use. Setting the filter disc 4 to a corrosion-resistant material can improve the service life of the device to a certain extent. The filter disc 4 and the outer ring are fitted with the inner cavity of the treatment tank 1, and the outer ring of the filter disc 4 is set to a rubber material, which can prevent the sewage from leaking from the gap between the filter disc 4 and the treatment tank 1, thereby making the device filter the sewage more completely.

A retaining ring 7 is fixedly provided on the inner wall of the treatment pool 1 . The retaining ring 7 is spaced a distance from the bottom of the treatment pool 1 . The airbag 6 is located above the retaining ring 7 . A plurality of arc grooves 8 are formed through the top of the retaining ring 7 .

In this embodiment, the retaining ring 7 is used to separate the filter disc 4 and the bottom of the treatment tank 1 by a certain distance, so as to facilitate some sewage to enter between the filter disc 4 and the bottom of the treatment tank 1, thereby generating buoyancy on the airbag 6, and the arc groove 8 enables the bottom sewage to come into contact with the airbag 6 in time.

Among them, the inner walls on both sides of the treatment tank 1 are provided with limiting grooves 9, the inner cavity of the limiting grooves 9 is provided with limiting rods 10, the outer ring of the limiting rod 10 is sleeved with a limiting block 11, one end of the limiting block 11 is fixedly connected to the filter disc 4, and a through hole 12 is penetrated through the top of the limiting block 11. The limiting block 11 moves on the outer ring of the limiting rod 10 through the through hole 12, and the top of the limiting rod 10 protrudes a certain distance from the top of the treatment tank 1, and U-shaped handles 13 are provided on both sides of the top of the filter disc 4.

In this embodiment, when the filter disc 4 floats up due to the influence of the airbag 6, the two sides of the filter disc 4 move on the outer circles of the two limit rods 10 through the limit blocks 11, thereby limiting the movement trajectory of the filter disc 4 to prevent the filter disc 4 from shaking and causing the impurities loaded on the top to slide down. At the same time, the device protrudes the limit rod 10 from the top of the treatment tank 1 by a certain distance. This arrangement can prevent the filter disc 4 from tipping over due to changes in gravity when it floats to the surface, thereby improving the reliability of the device.

The top of the filter disc 4 is also provided with an arc ring 14, and the cross section of the arc ring 14 is triangular.

In this embodiment, the arc-shaped ring 14 can form a protection on the top edge of the filter disc 4 to prevent the impurities accumulated on the top of the filter disc 4 from sliding off when the filter disc 4 floats to the surface of the water.

The outer ring of the arc-shaped ring 14 is provided with a plurality of bristles 15 , and the bristles 15 are in contact with the inner wall of the treatment pool 1 .

In this embodiment, as the filter disc 4 continues to rise, the retaining ring 7 connected to the top thereof drives the bristles 15 to clean the inner wall of the treatment pool 1, thereby removing impurities attached to the inner wall of the treatment pool 1 or the generated mosses, thereby improving the practicality of the device, and then the filter disc 4 can be taken out of the inner cavity of the treatment pool 1 through the U-shaped handle 13, thereby facilitating the treatment of impurities.
