[0048] With the above technical scheme of the present application, the cooperation of the upper stirring barrel assembly 3, the lifting stirring driving mechanism 4, the curing agent feeding port 5, the sludge stirring assembly 6, the lower stirring barrel assembly 7, the connecting block 9 and the moving mechanism 8 can make the curing agent fully and uniformly mix with the sludge, avoid the curing agent from caking, and through the cooperation of the two sets of lower stirring barrel assemblies 7 and the moving mechanism 8, the sludge stirring and sludge curing can be carried out simultaneously, a lot of time is saved, and the efficiency of sludge curing is improved. Under the action of the lifting stirring driving mechanism 4, the cooperating protrusion 404 on the rotating shaft 403 drives the stirring shaft 405 to move, so that the stirring shaft 405 can realize the lifting movement on the rotating shaft 403 and make the stirring shaft 405 rotate in cooperation with the driving motor 402, and under the cooperation of the cooperating groove 412 and the protrusion 410, the stirring shaft 405 can realize the lifting movement and fix the position of the stirring shaft 405, so that the position of the lower stirring barrel 701 is more convenient to replace. Under the action of the sludge stirring assembly 6, a plurality of stirring blades are arranged below the stirring shaft 405, which can effectively increase the contact range of the stirring blades and the sludge, make the curing agent more fully act on the sludge, prevent caking, and the cooperation of the trapezoidal clamping groove 604 and the trapezoidal clamping block 606 can make the stirring blade one 602 and the stirring blade two 603 more convenient to install and disassemble, and the stirring blades can be quickly fixed through the rotating shaft pin 608, so that the stirring blades are convenient to clean and replace after the device is used. Under the action of the lower stirring barrel assembly 7, the lower stirring barrel 701 can be heated through the electric heating ring 702, heating can also change the state of water in the sludge, so that it is more easily reacted with the curing agent, and through the cooperation of the fixed pin 710 and the pin hole one 704 and the pin hole two 709, the bottom cover 707 can be conveniently opened and closed, so that the cured sludge can be quickly and conveniently discharged from the lower stirring barrel 701 and reloaded into the uncured sludge. Under the action of the moving mechanism 8, the lower stirring barrel assembly 7 can be supported and limited through the supporting limiting rod 801, and through the cooperation of the threaded rod 802 and the moving block 804, the lower stirring barrel assembly 7 can be horizontally displaced, so that the two sets of lower stirring barrel assemblies 7 can be alternately matched with the upper stirring barrel assembly 3, and the efficiency of sludge curing is improved.
