Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1, the sewage purification treatment tower comprises a tower body 1 and a plurality of filter layers 2 arranged inside the tower body 1, wherein a water inlet pipe 101 is arranged at the top of the tower body 1, a water outlet pipe 102 is arranged at the bottom of the tower body 1, and a sewage discharge pipe 103 corresponding to each filter layer 2 is arranged on the tower body 1.

As shown in fig. 1 and 2, in the present embodiment, a main backwash pipe 4 is provided at a central axis position of the tower body 1, a plurality of backwash heads 3 are provided below each filter layer 2, and the backwash heads 3 are connected to the main backwash pipe 4. The back washing main pipe 4 is connected with a driving mechanism which drives the back washing main pipe to rotate.

The purpose of the drive mechanism is to: the back flushing heads 3 are positioned in the same plane, and when the back flushing heads 3 rotate by taking the central shaft of the tower body 1 as the center of a circle, the tracks form a circular surface, and the circular surface corresponds to the size of the filter layer 2. Namely, when the main flushing pipe 4 rotates, the backwashing heads 3 are driven to rotate together, and when the plurality of backwashing heads 3 rotate, each part of the filter layer 2 can be cleaned.

The driving mechanism is structurally shown in fig. 2 and comprises a motor 601, a belt 602, a belt pulley A and a belt pulley B603; the motor 601 is fixed on the top of the tower body 1, a belt pulley A is installed on an output shaft of the motor, a belt pulley B603 is sleeved outside the backwashing main pipe 4, and the belt pulley A and the belt pulley B603 are connected through a belt 602.

If the back washing head 3 is too far away from the filter layer, the back washing effect is not ideal, and if the back washing head is too close to the filter layer, the water leakage is affected. In order to avoid the situation, the main backwashing pipe 4 is also connected with a telescopic mechanism, the telescopic mechanism drives the main backwashing pipe 4 to move up and down, so that the backwashing head 3 is attached to the filter layer 2, and the backwashing head 3 can be far away from the filter layer 2 after backwashing is finished, thereby achieving good flushing effect.

In this embodiment, as shown in fig. 2, the telescopic mechanism includes a hydraulic cylinder 501, a force-bearing plate 502, and a top plate 503; the hydraulic cylinders 501 are fixed at the top of the tower body 1, and output shafts of the hydraulic cylinders 501 support and connect the stress plate 502; the main backwash pipe 4 penetrates through the force bearing plate 502, the top of the main backwash pipe is fixedly connected with a top plate 503, and a rolling groove and a rolling ball 504 are arranged between the top plate 503 and the force bearing plate 502. When the backwashing main pipe 4 works, the stress plate 502 is jacked up through the hydraulic cylinder 501, the stress plate 502 jacks up the top plate 503 through the balls 504, and the top plate 503 drives the backwashing main pipe 4 to move upwards; when the hydraulic cylinder 501 retracts, the top plate 503 and the main backwash pipe 4 automatically descend together under the action of gravity.

In this embodiment, the top plate 503 is provided with a rotary connector 5301, and the main backwash pipe 4 is connected to a backwash source through the rotary connector. During back flushing, the water may be flushed with air or water. The air flushing is preferably performed in the embodiment, the air backwashing is firstly performed during the flushing, then water is introduced from the main backwashing pipe 4 or the water inlet pipe 101, and the water is concentrated above the filter layer 2 and finally discharged from the sewage discharge pipe 103 because the bottom of the filter layer 2 is blocked by the backwashing head 3.

The belt 602 is selected to drive, because the belt 602 has certain elasticity, when the main backwash pipe 4 moves up and down, it generates certain displacement with the motor 601, and the belt 602 makes the main backwash pipe 4 always connected with the motor. However, the elasticity of the belt 602 may not be enough to satisfy the vertical displacement of the main backwash pipe 4, so that the belt pulley B603 and the main backwash pipe 4 are connected by the structural fit of the spline and the key groove, so that the belt pulley B603 can slide up and down along the main backwash pipe 4.

In the scheme, the back washing main pipe 4 penetrates the filter layer 2, a gap is formed between the filter layer and the back washing main pipe, and a sufficient filter tank is not obtained in order to avoid that sewage directly leaks from the gap; therefore, a plurality of baffle plates 401 corresponding to the filter layers 2 are provided in the backwash main pipe 4, and the baffle plates 401 disperse the water leaking from the gaps like an umbrella.

In this embodiment, the backwash main pipe 4 penetrates the upper cover of the tower body 1, and therefore the water inlet pipe 101 is provided along the circumferential position of the reverse main pipe 4. In order to increase the water inflow, a plurality of water inlet pipes 101 may be provided.

The above examples only represent preferred embodiments, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
