Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides two technical solutions:

[0032] Figures 1 to 4 A first embodiment is shown: a sludge dryer with a low-temperature evaporation device, comprising:

[0033] A bottom plate 1, a mounting frame 2 is fixedly mounted on the top of the bottom plate 1, and a cover shell 3 is fixed on the outer periphery of the mounting frame 2 above the bottom plate 1;

[0034] The dryer body 4 is mounted on the mounting frame 2 and is used to evaporate the water in the sludge at low temperature to dry the sludge;

[0035] A rotating assembly is installed above the bottom plate 1 and is used to drive the dryer body 4 to rotate;

[0036] A cleaning component, installed above the bottom plate 1, for cleaning the outer surface of the rotating component;

[0037] The lubrication component is installed above the bottom plate 1, cooperates with the movement of the cleaning component and lubricates the surface of the rotating component to prevent rust failure.

[0038] The rotating assembly includes a gear ring 5 fixed to the outer wall of the dryer body 4, a rotating shaft 6 is rotatably connected above the base plate 1, a gear 7 is fixed to the outer wall of the rotating shaft 6, a motor 8 is fixed above the base plate 1, the motor 8 is a reduction motor 8, the output end of the motor 8 is fixed to one end of the rotating shaft 6, and the gear 7 is meshingly connected to the gear ring 5.

[0039] The cleaning component includes an electric push rod 9 fixed above the base plate 1, a moving rod 10 is fixed at the output end of the electric push rod 9, a limiting block 11 is fixed on the base plate 1, the moving rod 10 is slidably connected to the inner wall of the limiting block 11, two brushes 12 are fixed on the moving rod 10 corresponding to the ring gear 5 and the gear 7, and the brush 12 is movably connected to the ring gear 5 and the gear 7.

[0040] This application sets up a cleaning component so that the rotating mechanism that drives the dryer body 4 to rotate can be cleaned, preventing the rotating mechanism from rusting and causing rust to remain on the surface of the rotating mechanism and affect the operation of the rotating mechanism. Compared with traditional sludge dryers, the cleaning component reduces the impact of rust on the rotating mechanism.

[0041] Figures 3 to 5 A second embodiment is shown, which mainly differs from the first embodiment in that the lubrication assembly includes a piston 13 fixed to the end of the moving rod 10 away from the electric push rod 9, a sleeve 14 is fixed on the base plate 1, the piston 13 is plugged into the inner wall of the sleeve 14, and a first infusion tube 15 is fixed to the end of the sleeve 14 away from the moving rod 10.

[0042] A liquid storage box 16 is fixed above the bottom plate 1, one end of the first infusion tube 15 is connected to the liquid storage box 16, a first one-way valve 17 is installed at the end of the first infusion tube 15 close to the liquid storage box 16, a second infusion tube 18 is connected to the end of the sleeve 14 close to the first infusion tube 15, a second one-way valve 19 is installed at the end of the second infusion tube 18 close to the sleeve 14, and an end of the second infusion tube 18 facing away from the second one-way valve 19 is aligned with the outer wall of the gear ring 5.

[0043] This application sets up a lubrication component so that the rotating mechanism can be lubricated by the lubricating oil output from the liquid storage box 16. On the one hand, it can prevent the rotating mechanism from rusting by lubricating the meshing part of the gear 7 and the ring gear 5. On the other hand, it can reduce the running jam caused by rust after rust occurs, which is practical.

[0044] Working principle:

[0045] The dryer body 4 is prior art and is not described in detail.

[0046] The driving motor 8 rotates the rotating shaft 6, and then the gear 7 rotates, driving the gear ring 5 to rotate, so that the dryer body 4 rotates, and the sludge inside the dryer body 4 is dried evenly.

[0047] The electric push rod 9 is extended and retracted to drive the moving rod 10 to move on the inner wall of the limit block 11, so that the brush 12 cleans the outer walls of the gear 7 and the gear ring 5 to prevent rust residue from remaining on the outer walls of the gear 7 and the gear ring 5; when the moving rod 10 moves, it drives the piston 13 to move on the inner wall of the sleeve 14. When the electric push rod 9 contracts, the moving rod 10 drives the piston 13 away from the first infusion tube 15, so that the first infusion tube 15 draws the lubricant in the liquid storage box 16 into the sleeve 14 through the first one-way valve 17. When the electric push rod 9 is extended, the piston 13 squeezes the inner wall space of the sleeve 14, so that the lubricant flows into the second infusion tube 18 through the second one-way valve 19, and the lubricant is discharged from the second infusion tube 18 and drips on the surface of the gear ring 5, so that the surface of the gear ring 5 is lubricated, and then the gear 7 is lubricated together.
