Heating is only achieved through the cylinder with a heating jacket, resulting in poor heating effect and low drying efficiency. Moreover, conventional three-in-one filter washing and drying machines generally have the discharge port designed on the bottom plate or on the cylinder wall near the bottom plate because the cylinder does not have a rotation function.

The heating tube 93 is arranged in a spiral coil (see...). Figure 4 ) or finned arrangement (see Figure 5 The bottom end of the end cap 91 is provided with a filtrate outlet. The bottom of the filter base plate 92 is connected to the end cap 91 through a reinforcing rib plate 94.

[0031] The top left and right sides of the frame 14 are respectively provided with a left bearing seat 5 and a right bearing seat 18.

[0032] The left and right sides of the cylinder 8 are respectively provided with a left rotating shaft 41 and a right rotating shaft 42 for driving the cylinder 8 to rotate in the vertical plane; the left rotating shaft 41 and the right rotating shaft 42 are respectively arranged in the left bearing seat 5 and the right bearing seat 42.

[0033] The rotary drive motor 3 is mounted on the left side of the frame 14 via a support base, and the rotary drive motor 3 is connected to the left rotating shaft 41 via a mechanical seal; the rotary drive motor 3 drives the left rotating shaft 41 to rotate, causing the cylinder 8 to rotate in the vertical plane.

[0034] The left rotating shaft 41 has a central heat pipe 6 parallel to its axis inside. The outer wall of the central heat pipe 6 and the inner wall of the left rotating shaft 41 form a heat medium inflow channel b for the heating medium to flow into the heating jacket 7. The interior of the central heat pipe 6 forms a heat medium outflow channel a for the heating medium to flow out of the heating pipe 93. The heat medium inflow channel b is connected to the heat medium inlet of the heating jacket 7 through the heat medium pipe 2. The heat medium outlet of the heating jacket 7 is connected to the heat medium inlet of the heating pipe 93 through the heat medium pipe 16. The heat medium outlet of the heating pipe 93 is connected to the heat medium outflow channel a through the heat medium pipe 10.

[0035] The right-side rotating shaft 42 has a central feed pipe 17 parallel to its axis inside.

One end of the central feed pipe 17 is connected to the feed valve at the top of the cylinder 8 through the feed pipe 19, and the other end is provided with a material input valve group. The material input valve group includes a solid-liquid mixed slurry inlet valve, a detergent inlet valve and a nitrogen inlet valve arranged in parallel. The central feed pipe 17 can be used for solid-liquid mixed slurry feeding, detergent feeding and nitrogen (inert protective gas) feeding. The outer wall of the central feed pipe 17 and the inner wall of the right-side rotating shaft 42 form a filtrate outlet channel f for filtrate to flow out of the bottom filtration device. One end of the filtrate outlet channel is connected to the filtrate outlet through the filtrate pipe 15, and the other end is provided with a vacuum valve group.

The filtrate and detergent in the solid-liquid mixture are discharged from the cylinder 8 through the filtrate outlet, filtrate pipe 15, and filtrate outflow channel f. After filtration and washing, the solid material on the filter base plate 92 is heated not only by the heat medium in the heating jacket 7 and the central heat pipe 6, but also by the heating pipe 93 under the filter base plate 92, greatly improving heating efficiency. Furthermore, since the filtrate outflow channel f can also be used as a vacuum channel during drying, vacuuming can accelerate drying. After heating and drying, the rotary drive motor 3 drives the cylinder 8 to rotate 180 degrees via the left rotating shaft 41 and the right rotating shaft 42, and through oscillation, the dry material falls off the filter base plate 92 and is discharged from the cylinder 8 through the discharge valve 1.
