The sludge fermentation mechanism is located inside the main body mechanism, and the cleaning placement mechanism is located at the lower end of the sludge fermentation mechanism. The main body mechanism includes a box body, a maintenance plate, fixed legs and a mud inlet pipe. The maintenance plate is movably installed at the front end of the box body, and the fixed legs are fixedly installed below the maintenance plate. By installing the sludge fermentation mechanism, the agitator can stir the internal sludge, and the sludge can be turned over and stirred at one time, which is helpful for fermentation. The heater can heat the inside of the fermentation box to make the stirring more uniform, facilitate sludge fermentation, and improve the sludge fermentation efficiency of the sludge fermentation device for sludge composting treatment.

[0004] When the device collects the fermented sludge, it is necessary to place the placement box on the upper surface of the support plate below the box body, and then receive the sludge discharged from the fermentation box after fermentation. The placement box is manually pulled horizontally from the upper surface of the support plate below the box body before it can be removed. At this time, the top opening of the placement box is in an open state, and the top of the placement box is blocked by the box body. Manually pulling the placement box on the support plate horizontally may cause the sludge in the placement box to spill out. Utility Model Content

The lifting plates 4 can be lifted and lowered by the setting of four electric push rods 3, and then a slide groove 5 is opened on the opposite sides of the two lifting plates 4, and then a screw rod 6 is set in the two slide grooves 5 for limited rotation, and a servo motor is connected to one end of the screw rod 6, and the screw rod 6 can be rotated and adjusted by the setting of the servo motor, and a slider 7 is threadedly sleeved on the outer side of the two screw rods 6, and a support plate 8 is arranged between the two sliders 7, and finally a placement box 9 is arranged on the upper surface of the support plate 8, and the fermented sludge is loaded and collected by the placement box 9;

[0022] When the placement box 9 is moved out from under the fermentation outer box body 1, the servo motor can be used to adjust the rotating screw 6, and then the slider 7 is driven to move by rotating the screw 6. The supporting plate 8 and the placement box 9 arranged on the upper surface of the supporting plate 8 are moved by the moving slider 7, so that the supporting plate 8 drives the placement box 9 to move out from under the fermentation outer box body 1, thereby facilitating the removal of the placement box 9.

[0023] As a further implementation of this embodiment, Figure 1-4As shown, a mud inlet pipe 10 is provided at the top of the fermentation outer box body 1, and then a fermentation box 11 connected to the mud inlet pipe 10 is provided in the fermentation outer box body 1, and a rotating shaft 12 is provided in the fermentation box 11 for limited rotation, and then a plurality of stirring rods 13 are provided on the outer wall of the rotating shaft 12 and located in the fermentation box 11, and the sludge in the fermentation box 11 can be mixed and stirred by the coordinated arrangement of the rotating shaft 12 and the stirring rods 13, and one end of the rotating shaft 12 is connected to the power output end of the motor after passing through the fermentation box 11 and the fermentation outer box body 1 at one time, and heat conducting plates 15 are provided on both sides of the fermentation box 11, and heaters 16 are provided in the fermentation outer box body 1 and located on both sides of the fermentation box 11, and the fermentation box 11 can be heated by the coordinated arrangement of the heat conducting plates 15 and the heater 16;

[0024] Specific working principle:

[0025] When the sludge is fermented, the sludge is firstly put into the fermentation box 11 through the mud inlet pipe 10, and then the stirring rod 13 is driven by the rotating shaft 12 to stir the sludge in the fermentation box 11. At the same time, the sludge in the fermentation box 11 is heated by the cooperation of the heat conducting plate 15 and the heater 16, so that a good fermentation temperature is maintained in the fermentation box 11. After the fermentation is completed, the sludge in the fermentation box 11 is discharged through the mud outlet pipe 14. When discharging, the placement box 9 is first placed on the upper surface of the support plate 8, and then the support plate 8 and the sludge arranged on the support plate 8 are driven by the rotating screw 6 threadedly driving the slider 7. The placement box 9 on the upper surface of the support plate 8 is moved to the mud outlet pipe 14 below the fermentation outer box body 1, and then the height position of the support plate 8 and the placement box 9 arranged above the support plate 8 is adjusted by the electric push rod 3 to avoid that when the sludge is discharged from the mud outlet pipe 14, the placement box 9 is too low, resulting in splashing of sludge during discharge. After the discharge is completed, the slider 7 is driven to move by the screw rod 6 again, and then the support plate 8 and the placement box 9 arranged on the upper surface of the support plate 8 are driven by the slider 7 to move out from under the fermentation outer box body 1, thereby facilitating the removal of the placement box 9 arranged on the upper surface of the support plate 8.
