As shown in Figures 1, 2 and 3, the biogas residue biogas slurry processor includes a box body 1 and a filter device. A plurality of filter devices are respectively arranged in the length direction of the box body 1, and the box body space between each filter device forms a filter cavity. Segment 2, the tank 1 of the first filter chamber segment 2 is provided with a waste water inlet 23, and the bottom of the tank 1 of the last filter chamber segment 2 is provided with a filtrate outlet 3, and each filter device is inclined towards the direction of the filtrate outlet and forms an angle α with the horizontal, which is 70°. The filtering device includes a drum 4, a filter screen 5, a filter screen frame 6, a side plate 7, a sewage discharge tank 8 and a slag removal mechanism. The direction of the filtrate outlet 3 decreases step by step. The slag removal mechanism includes a scraper 13, a scraper shaft 14, a rubber plate 15 and a spring 16. Side plates 7 are respectively fixed on the two side walls of the box body 1. The side of the network frame 6 is fixedly connected, and the two rollers 4 are respectively fixed on the bearing seats 10 at the upper and lower ends of the side panels 7 on both sides through the bearings 9, and the roller 4 at the upper end of the side panels 7 is connected to the motor 11 fixed on the box 1 through the bearings. Connected, a plurality of rotatable roller parts are evenly arranged on the side plates 7 on both sides between the upper and lower rollers 4, and the roller parts include the roller shaft 17 and the roller bushing set on the roller shaft 17 18. A filter screen 5 is set between the upper and lower rollers 4, and the filter screen 5 is placed outside the idler part; the sewage discharge tank 8 with a sewage discharge port 12 on the side of the box body 1 is fixed on the side plate opposite to the filter screen frame 6 7 side; one end of the spring 16 is fixed on the end of the scraper shaft 14 close to the side plate 7, the other end of the spring 16 is fixed on the side of the box body 1, and the scraper shaft 14 is fixed between the tops of the side plates 7 on both sides through bearings. A scraper 13 is fixed on the side of the scraper shaft 14 close to the filter screen 5 in the length direction of the body 1, and the scraper 13 is in contact with the filter screen 5; The bottom is close to the upper end surface of the sewage discharge tank 8; the bottom of the sewage discharge tank 8 of the present invention is inclined downward, and the sewage outlet 12 located on the side of the box body 1 is located at the lowest point of the sewage discharge tank 8, and the bottom of the box body 1 of each filter cavity section 2 An aeration pipe 19 is provided; the casing 1 top of each filter chamber section 2 is provided with a case cover 20, and the bottom of the case cover 20 is provided with a stirring paddle 21 extending into the filter chamber section 2, and the top of the case cover 20 is provided with a Stirring motor 22 that stirring paddle 21 is connected.
