The invention discloses a method and device for sludge filter cake aerobic air drying. The method mainly includes that: sludge filter cake is dispersed into granular layers and dry air at certain temperature is fed into slowly moving or overturning sludge granular layers at positive pressure; physical or chemical sterilization treatment is carried out on slowly moving or overturning sludge granules; tail gas containing sludge moisture is exhausted at negative pressure outside the sludge granular layer and is discharged after washing; and the dried sludge granules are further smashed in conveying process by a screw conveyor, thus meeting the requirement of reclamation utilization. The invention has the following advantages: firstly, heat transfer mass transfer efficiency in drying is high and drying energy consumption is low; secondly, drying is speeded up and deodorization effect is realized on the sludge; thirdly, the sludge granules are stable and safe in production in drying process; fourthly, the dried tail gas can be discharged by environmental protection standard after washing; and fifthly, the discharged sludge granules are loose, thus being convenient for reclamation utilization.

The invention provides a clamping fixture, which comprises a first cylinder, a second cylinder, a push-pull rod, a spring, a magnet and a cover. The first cylinder is a hollow cylinder with openings at two ends, and comprises a big cylinder and a small cylinder which are concentrically arranged. The joint of the big cylinder and the small cylinder protrudes out of the internal surface of the first cylinder to form a lug boss with a through hole. The second cylinder is a hollow cylinder comprising a connecting end and a clamping end, wherein the connecting end is connected with the small cylinder, and the clamping end is used for clamping objects. The push-pull rod is movably accommodated in the first cylinder and the second cylinder. One end of the push-pull rod forms a finger press part protruding out of the big cylinder. The spring is sleeved on the push-pull rod and accommodated in the first cylinder to provide elastic-restoring force for the push-pull rod to be away from the second cylinder. The magnet is fixed at the other end of the push-pull rod and positioned in the second cylinder and the size of the magnet is more than or equal to that of the through hole. The cover is fixed at one end of the big cylinder near the finger press part so as to prevent the push-pull rod from pulling out of the first cylinder.
