[0049] By adopting the above technical solution, feces and sewage can enter the first compartment 124 and the storage cavity 123 respectively.
[0050] Working principle: In actual use, the feces and sewage inside the two toilets 102 enter the processing box 107 through the first conveying pipe 105 and the second conveying pipe 106 respectively, and the crushing roller 108 is driven to rotate. The crushing roller 108 drives another first gear 109 to rotate through the first gear 109, so that the other first gear 109 drives another crushing roller 108 to rotate, so that the two crushing rollers 108 rotate in opposite directions to complete the crushing of the feces and sewage. Then, the crushed feces and sewage fall onto the rotating plate 111, and wait for a period of time, so that the sewage in the feces and sewage enters the through hole 113 through the triangular plate 112, and then falls onto the inclined plate 22 through the through hole 113, and passes through the inclined plate 2 2 enters the third conveying pipe 119, enters the first compartment 124 through the third conveying pipe 119, and then drives the two electric push rods 130 to drive the two extrusion plates 131 to approach each other, thereby squeezing the feces and sewage, so that the sewage inside the feces and sewage is squeezed out and continues to enter the first compartment 124, and then drives one of the rotating rods 110 to rotate, driving the rotating plate 111 to rotate, and the rotating rod 110 can drive the second gear 114 to rotate while rotating, and the second gear 114 drives the third gear 115 to move in the opposite direction, and the third gear 115 drives the rotating shaft 116 to rotate, and the rotating shaft 116 drives another rotating shaft through the synchronous belt 117. The rod 110 rotates, thereby rotating the other rotating plate 111. At this time, the feces and sewage that have lost moisture fall onto the trapezoidal plate 121 and enter the storage chamber 123 through the fourth conveying pipe 120. When the rotating plate 111 rotates, it can apply pressure to the inclined plate 22 and the movable plate 21 to make them descend, thereby avoiding blocking the rotating plate 111 and making it rotate smoothly. The movable plate 21 can squeeze the spring 24 while descending, which is convenient for the subsequent resetting of the movable plate 21. The feces and sewage in the storage chamber 123 are decomposed by microorganisms, which is convenient for subsequent treatment. At this time, the sewage in the first compartment 124 is fermented and precipitated, and the microorganisms therein perform anaerobic The solid particles in the sewage will gradually settle to the bottom of the pool to form a sludge layer, while lighter substances such as grease and fat will float to the surface to form a scum layer; the middle layer is a relatively clear liquid layer, and then the liquid layer enters the second compartment 125 for secondary sedimentation, until the liquid in the second compartment 125 enters the third compartment 126, and the liquid in the third compartment 126 enters the purification box 127 for aerobic treatment, and the treated liquid enters the toilet 102 through the sixth delivery pipe 128 and the seventh delivery pipe 129 respectively, providing a water source for flushing the toilet 102; it should be noted that the synchronous belt 117 can adopt the common internal tooth synchronous belt on the market to reduce hysteresis.
[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
