[0038] Specifically, as shown in Figure 6 and Figure 7 , the outer side of blade plate 10 is formed with blade strip 21 at intervals, and one end of blade strip 21 is located outside the edge of blade plate 10, so that the crushing of the mud plate is accelerated.

[0039] Specifically, material port 2 and ventilator 3 are communicated with inner tube 8, and the port of inner tube 8 is located outside the edge of material port 2 and ventilator 3, so that the high-low difference is formed to prevent the sludge from overflowing.

[0042] Specifically, the first cylinder 16 and the second cylinder 19 are high-temperature resistant cylinder parts, and the spring 20 is a high-temperature resistant spring, facilitating use and long service life.

[0043] Working principle:

[0044] The structure proportions of the drawings are for the convenience of viewing, and the actual size and proportion are subject to the production requirements;

[0045] A support group frame is installed below the outer cylinder 1, and a driving device is installed on the support group frame to drive the outer cylinder 1 to move obliquely to discharge the material. Reference is made to the existing equipment, and no limitation is made;

[0046] The wet sludge is loaded into the inner cylinder 8 from the position of the material inlet 2. The adjusting device can be clamped on the adjusting device mounting port 9 with the aid of the convex strip 12. The blade plate 10 of the adjusting device is located inside the inner cylinder 8. All the adjusting devices do not contact each other. Due to the height difference between the port of the inner cylinder 8 and the ports of the material inlet 2 and the ventilator 3, the sludge cannot flow back into the ventilator 3, avoiding the blockage of the air inlet pipe 6. Due to the internal space of the inner cylinder 8 being separated by the adjusting devices, the motor 7 drives the entire device to rotate slowly. During the rotation, the material inlet 2 is continuously loaded, filling each separated groove. During the filling process, the air inlet pipe 6 continuously performs high-temperature blast drying. The sludge is dried by strong hot air, and it is fixed on the adjusting device, so that the dried mud pieces will not fall down due to rotation.

[0047] When the sludge in the inner cylinder 8 is dried, the inner rod of the first cylinder 16 is extended, the movable block 15 is pressed down, the clamping group plate 14 is pressed down, the inner connecting plate 13 connected with the adjusting plate 11 is pressed down, the adjusting plate 11 is close to each other, the included angle between the blade plate 10 is reduced, the blade plate 10 is separated from the sludge, the convex strip 12 is separated from the adjusting device mounting port 9, then the inner rod of the second cylinder 19 is moved backward with the horizontal plate 18, so that the blade plate 10 and the adjusting plate 11 are moved to the outside of the inner cylinder 8, at this time the sludge is loose, and the device rotates at high speed, the sludge will fall off from the inner wall of the inner cylinder 8, then the inner rod of the second cylinder 19 stops moving, the inner rod of the first cylinder 16 is retracted, so that the adjusting plate 11 loses pressure, and the spring 20 rebounds, the innermost convex strip 12 is clamped on both sides of the adjusting device mounting port 9, only the blade plate 10 is clamped in the inner cylinder 8, then the device is accelerated, the dry sludge in the inner cylinder 8 hits the blade plate 10 into soil, the blade strip 21 can speed up the crushing of the sludge, because the material port 2 and the ventilator 3 are arranged obliquely, the sludge entering the inner cylinder 8 will automatically slide down into the inner cylinder 8, finally the whole machine is inclined, and the sludge is poured out.

[0048] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
