When the engagement portion 431 and the rotating plate 3115a drive the blocking block 313 to move downwards, strong alkaline materials can enter from a gap between the outer shell 321 and the blocking block 313, meanwhile, the bottom of the grinding piece 322 is in abutting sealing with the bottom of the outer shell 321, the materials are prevented from directly entering the barrel 12 to be dissolved without grinding, then the circular plate 43 and the rotating plate 3115a are in non-contact, the materials continuously enter between the outer shell 321 and the grinding piece 322 to be ground and crushed, the materials continue to rotate until the engagement portion 431 and the rotating plate 3115a drive, at the moment, the blocking block 313 can be driven to move upwards, the top of the outer shell 321 is sealed to close feeding, meanwhile, the grinding piece 322 below the grinding piece 322 is not in abutting connection with the outer shell 321, the ground materials can be placed into the barrel 12 to be stirred and dissolved, and the solid strong alkaline materials can be automatically converted into liquid;
when the motor 41 is started, the shaft lever 44 drives the first transmission rod 3231 to rotate through the transmission of the driving teeth 441 and the driven teeth 3232, and further drives the grinding part 3222 to rotate all the time through the second gear set 3233 for grinding and crushing;
In addition, during grinding and crushing, the linkage plate 61 can synchronously rotate along with the shaft lever 44, when the protruding block 611 contacts the inner end of the knocking rod 63, the knocking rod 63 is outwards ejected for a certain distance, the spring 66 is compressed, when the protruding block 611 leaves the knocking rod 63, the knocking rod 63 is pulled back to reset under the action of the compressed spring 66, so that circular reciprocating knocking is formed, alkaline materials attached to the inner wall of the shell 321 are knocked off, and after the grinding and crushing and knocking, solid strong alkaline materials fall into the mixing drum 1 to be mixed and dissolved, so that the automatic conversion of solids to liquids is realized;
When the liquid is required to be converted into the solid, the heating pipe is started only through the PLC controller, and the solution is heated to precipitate the strong alkaline material in the solution into the solid, so that the automatic conversion from the liquid to the solid is realized.
