[0039] Working principle: The present application is a machine-made sand washing sludge slurry dewatering device, which is equipped with a sand washing structure 1. When in use, the sand and gravel are transported to the inside of the cleaning barrel 109 along the feed pipe 110, and then the water source is connected to the water injection pipe 101. After the sand and gravel enter the cleaning barrel 109, they are broken up by the cooperation of the low-speed motor 103, the transmission shaft 114, the breaking up barrel 115 and the first stirring blade 116, so that the water source can fully contact the sand and gravel, thereby washing away the sludge in the sand and gravel as much as possible. After the stirring and flushing are completed, the sludge and sand and gravel fall uniformly to the lower end of the cleaning barrel 109, and the sludge water is discharged under the action of the filter screen 113. The sand and gravel are conveyed to the next program along the extended conveying auger shaft 105, thereby improving the efficiency of preliminary flushing and decomposition.

[0040] By setting up the mud processing structure 2, the washed sludge water falls into the interior of the collection tank 202 for preliminary sedimentation, and then the sludge water is transferred to the interior of the first placement barrel 201 under the action of the first sludge pump 203, and then a proper amount of flocculant is added inside, and then the first motor 204 and the bottom frame 207 cooperate with the second stirring blade 208 to fully stir it so that it is fully fused, and then the stirring is stopped, and the floccules fall down, and one end of the fan-shaped filter screen 210 is pressed open under the action of gravity, and the floccules fall uniformly to the bottom end of the first placement barrel 201, and the fan-shaped filter screen 210 that is free from the pressure of gravity returns to its original state under the action of the torsion spring 209, so that it is convenient for the next use, thereby realizing the effective separation of clean water and floccules, and the floccules after separation are transferred to the next step under the cooperation of the first delivery pump 510 and the second connecting pipe 509, and the clean water inside can be used to continue to wash sand and gravel.

[0041] By setting up the sand and gravel processing structure 6, when in use, the sand and gravel transmitted by the extended conveying auger shaft 105 are collected by the processing barrel 601, and then the internal multiple heating tubes 607 are started, and the internal sand and gravel are stirred and dried with the cooperation of the second motor 604 and the internal first connecting plate 606. The excess water falls along the filter plate 608 to the inside of the processing barrel 601, and is returned to the inside of the first placement barrel 201 through the second sludge pump 4 and the conveying pipe 3 for continued flocculation and purification, thereby realizing water circulation. At the same time, the sand and gravel after drying are discharged with the cooperation of the auger shaft 603 and the material pipe 602, so as to facilitate the processing of the next batch, and the sand and gravel after drying can be directly put into use.

[0042] By setting up the sludge dewatering structure 5, when in use, the flocs in the first placement barrel 201 are transferred to the inside of the dewatering box 501 through the cooperation of the first delivery pump 510 and the second connecting pipe 509. During the transfer process, the material placement frame 514 moves it to the inside of the dewatering box 501 under the action of the hydraulic telescopic device 503, and the first connecting pipe 508 uniformly transfers the flocs to the inside of the material placement frame 514. The two sides can receive them alternately, and then return to their original positions. They are dried and dried under the action of the heating plate 513. Excess water falls to the inside of the dewatering box 501 along the orifice plate 515, and then is transferred back to the inside of the first placement barrel 201 through the cooperation of the second delivery pump 512 and the third connecting pipe 511, so as to realize recycling and reduce resource waste. The heat generated during the drying process is recovered by the hot air recovery pipe 505 and recovered to the inside of the spiral tube 506, so as to realize heat energy recovery and improve resource utilization.
