The support frame 1 is provided with a head support 2 and a tail support 3 at two ends thereof, respectively. The water receiving tray 5 is correspondingly arranged below the rotary filtering mechanism 4 and connected to the support frame 1. The water receiving tray 5 is connected to an external drain tank 134 through a drain pipe 6. The rotary filtering mechanism 4 is horizontally rotatably arranged on the head support 2 and the tail support 3 and comprises a rotary frame formed by a support end disc 41, a first support ring plate 44, a second support ring plate 45, the support end disc 41 and a plurality of auxiliary connecting beams 43 arranged along the circumference of the rotary frame, and a cylindrical filter screen arranged on the rotary frame. A plurality of spiral discharge pieces 48 are arranged on the inner wall of the rotary frame, and a discharge chute 7 is connected to the outlet end of the spiral discharge pieces 48. Down washing wastewater enters the rotary filtering mechanism 4 and is filtered by the filter screen.

The spraying main pipe 81 is connected to an external water source. The spraying main pipe 81 is correspondingly arranged above the rotary filtering mechanism 4. During the rotary filtering process of the rotary filtering mechanism 4, the spraying system 8 synchronously supplies water for spraying, so that the down moves to the tail along the connection between the spiral discharge pieces 48 and the rotary frame with the micro water flow, and is discharged from the discharge chute 7.

During installation, the roller 113 is correspondingly clamped in the support inclined groove 112 through the roller shaft 1131, and the roller 113 is correspondingly pressed on the roller bracket 111 by the self-weight of the rotary filtering mechanism 4, so as to avoid the risk of falling off of the roller 113 during operation.
[0025] In a preferred embodiment, as shown in Figures 4-5 and Figure 9 In this embodiment, the filter screen is not in a one-piece structure, but is in a multi-piece filter screen structure which is assembled along the circumference of the rotary frame. Specifically, the connecting auxiliary beam 43 includes five beams which are arranged along the circumference of the two groups of support end discs 41. The laying area of each filter screen is formed between adjacent two connecting auxiliary beams 43. The two long sides of the filter screen piece are respectively laid to the corresponding connecting auxiliary beams 43. Adjacent two connecting auxiliary beams 43 are provided with a screen pressing grid plate 49 which is pressed on the filter screen. The screen pressing grid plate 49 includes a side beam which is arranged along the length direction of the rotary filtering mechanism 4. Figure 9The side beams and the arc-shaped end beams are welded to form a sector structure which is adapted to the circumference of the rotary filtering mechanism, so that the filter screen pieces are pressed on the outer wall of the rotary frame, facilitating regular cleaning, replacement and maintenance of the rotary screen. A plurality of pressing members 410 are arranged at intervals along the auxiliary beam 43, and the two ends of the pressing member 410 are correspondingly pressed on the side beams of the screen pressing grid plate 49 on the two sides of the auxiliary beam 43. The pressing member 410 is fixedly connected with the auxiliary beam 43 through a locking member 411.

The locking member 411 can adopt a fixed screw, and a plurality of fixed screw holes 46 (as shown in Figure 2 ) are arranged at intervals on the auxiliary beam 43 for connection of the fixed screw.
[0026] As shown in Figures 7-8 , the down feather recycling device further comprises a civil foundation 13 for fixedly mounting the support frame 1. The civil foundation 13 comprises a concrete base 131 and a drainage channel 134 formed thereon, and the drainage channel 134 is provided with a drainage side ditch 135 at the tail end. The civil foundation 13 is provided with a sewage tank 136 at the tail end, and the sewage tank 136 is provided with a sewage ditch 137 at the bottom, and a filter grid plate 132 is correspondingly arranged on the bottom of the sewage tank 136 in the sewage ditch 137. The filter grid plate 132 is provided with a strong discharge pipe site hole 133 corresponding to the sewage ditch 137, and a strong discharge pipe is connected in the strong discharge pipe site hole 133. The strong discharge pipe is connected with an external diaphragm pump to regularly discharge the sewage stored in the sewage ditch 137, and the filter grid plate 132 is regularly used for down feather recycling. The drainage side ditch 135 is communicated with the sewage tank 136 through a pre-buried communication pipeline 138. It should be noted that, in order to reduce the sewage collection efficiency, a screen plate 139 is vertically arranged at the rear end of the sewage tank 136. The screen plate 139 divides the sewage tank 136 into two parts, and the filter grid plate 132 is located in the front part of the sewage tank 136. The front end of the communication pipeline 138 is communicated with the drainage side ditch 135, and the rear end of the communication pipeline 138 extends into the rear part of the sewage tank 136, and the sewage can be directly discharged through the strong discharge pipe.

This arrangement can improve the processing capacity of the rotary filtering mechanism and reduce non-fault downtime.
[0028] The working principle or working method of the present application: when working, the down water washing wastewater enters into the rotary filtering structure through the feeding pipe 12, the down is intercepted by the filtering screen, the wastewater flows into the water receiving tray 5 and then is discharged into the sewage pool for storage. When the filtering screen rotates, the spraying system 8 washes the down and pushes the down to the discharge chute 7 for recycling along with the rotation of the spiral discharge sheet 48.
[0029] The above is the preferred embodiment of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application.
