[0030] A first spring 31 is fixedly connected between the extrusion rod 30 and the fixing sleeve 32 for resetting the extrusion rod 30. At the same time, the elastic force of the first spring 31 is used to provide an extrusion force to the extrusion rod 30 to clamp and fix the impurities, so that the impurities can move with the movement of the extrusion rod 30 and the impurities can be discharged smoothly.

At the same time, a stirring device driven by a motor can be set at the bottom of the device to stir the feces in the transfer box 1, so that the added agent can be mixed with the feces more evenly, so as to facilitate the subsequent treatment of the feces, and the stirring mechanism is a conventional technical means, that is, the stirring rod is driven by a motor to rotate to complete the stirring of the feces.

[0036] A box door 7 is provided on the surface of the processing box 5 so that the processing box 5 can be opened to facilitate subsequent staff to take out the impurities therein.

[0037] Working principle: When in use, the feces mixture is injected into the transfer box 1 through the injection tube 6, and then the feces falls into the discharge box 19. At this time, as the first motor 8 is started, the two reciprocating screws 10 are driven to rotate through the transmission of the first pulley 11 and the first belt 9, thereby driving the push block 36 to reciprocate in the slide groove 35, so that the inclined surface of the push block 36 squeezes and pushes the surface of the movable plate 15, thereby driving the movable plate 15 to slide and rise, and compressing the second spring 16, and the rise of the movable plate 15 starts The movable spray pipe 28 slides and rises in the discharge box 19, so that a gap appears at the bottom of the discharge box 19, so that the feces in the discharge box 19 are discharged from the gap, and then after the pushing block 36 is separated from the movable plate 15, under the elastic force of the second spring 16, the blocking block 20 returns to its original state, so that during the operation of the device, the blocking blocks 20 are opened one by one, so that the feces mixture can fall on the screening mechanism 21 more evenly, thereby reducing the filtering pressure of the screening mechanism 21 on the feces liquid and improving the filtering efficiency of the device on the feces mixture.

[0038] At the same time, the second motor 14 is started, and the second belt 17 and the second pulley 18 are used to drive the cross bar 2101 to rotate, thereby driving the third spring 2107 to rotate through the cooperation of the connecting groove 2104 and the square rod 2103, and then driving the bevel gear 2108 to rotate, and through the meshing of the four bevel gears 2108, some cross bar 2101 and vertical rod 2102 are rotated, so that impurities falling on the cross bar 2101 and the vertical rod 2102 can be transported under the rotation of the cross bar 2101 and the vertical rod 2102, so that the impurities are close to the rotating roller 22. When the impurities contact the extrusion rod 30, if the impurities are relatively soft impurities such as sanitary napkins, the extrusion rod 30 and the arc surface of the lower partition plate 38 cooperate to squeeze the impurities, so that the feces mixture absorbed by them can be squeezed out, reducing the feces mixture absorbed by them, which is convenient for subsequent staff to take them out and treat them. The first spring 31 is pressed against the first roller 22 and pressed against the second roller 22, and the second roller 22 is pressed against the first roller 22. The first spring 31 is pressed against the first roller 22, and the second roller 22 is pressed against the second roller 22. The first spring 31 is pressed against the first roller 22, and the second roller 22 is pressed against the second roller 22.

The first spring 31 is pressed against the first roller 22, and the second roller 22 is pressed against the second roller 22.

[0039] After the impurities fall on the filter 25, the agent in the liquid storage cylinder 2 is sucked through the pump body 4, so that the agent is sprayed on the surface of the impurities through the spray pipe 28, and the impurities are further cleaned, so as to facilitate the subsequent removal and cleaning of the impurities. When the agent is injected into the processing box 5, the agent impacts the turbine blades 34, thereby driving the spray pipe 28 of the driving device to rotate, so that the agent is sprayed more evenly, and at the same time drives the rotating shaft 26 and the disturbance rod 27 to rotate, and the impurities on the filter 25 are stirred, so that the impurities can be fully cleaned, thereby improving the cleaning quality of the impurities and reducing the psychological burden of the subsequent staff when cleaning the impurities. At the same time, after the agent rinses the impurities, the agent enters the transfer box 1 through the opening at the bottom of the processing box 5 and mixes with the feces mixture in the transfer box 1.
