In the initial state of the device of the present invention, the tip end surface of the stopper 30 is brought into contact with the ceiling wall of the restriction groove 31 by the pressing by the pressing spring 32, and the convex portion of the pressing cam 28 is most distant from the stopper 30, Both the solenoid valve 38 and the opening/closing valve 63 are in the closed state.

At the time of use, first, a wastewater treatment agent is put into the stirring cavity 34 through the hopper 64 to control the opening/closing valve 63 so that the wastewater passes through the wastewater pipe 62 and the impeller cavity is discharged. 11, the impeller 12 is driven to rotate again, and after the impeller 12 rotates, the first transmission wheel (not shown), the third transmission wheel 59, and the second transmission wheel ( (Not shown) and the conveying wheel 16 on the right side are driven to rotate, and after the conveying wheel 16 has rotated, solid contaminants in the wastewater are separated via the separation belt 18 and then the shredded cabinet The tee 55 is moved into the tee 55, and the drive motor 56 is controlled and rotated at this time. After the drive motor 56 rotates, the upper shredder shaft 54, the first rotating gear 52, and the first rotating gear 52 The two-turn gear 53 and the lower shredder shaft 29 are driven to rotate, and the solid contaminant separated by this is cut into particles.

The wastewater separated in the first stage drops into the compression cavity 19 through the separation cavity 14, and at the same time, the pressing cam 28 is rotationally driven after the lower shredder shaft 29 is rotated. By pressing the stopper 30, the upper compression plate 20 is interlocked and the filter sponge 261 is compressed downward, whereby the separated wastewater is filtered by the filter sponge 261 and then the stirring cavity is pressed. The raw material receiving cavity 50 is pressed into the raw material receiving container 34 rapidly, and at this time, the finely cut solid granules fall into the raw material receiving cavity 50, and the raw material receiving box 49 is eccentrically mounted. After the solid granules are filled with solid granules, the raw material receiving box 49 is rotated 180 degrees by interlocking the fourth rotating shaft 47, and the solid granules in the raw material receiving cavity 50 are collected in the collecting box 45. And transmits to the outside through a transmission device, and at the same time, after the fourth rotating shaft 47 rotates, the fifth transmission wheel 42, the fourth transmission wheel 41, and the agitator. The shaft 35 and the stirring arm 36 are rotationally driven to rapidly stir the wastewater mixture in the stirring cavity, and after the stirring is completed, the solenoid valve 38 is controlled to open the wastewater mixture to the outside. And the next precipitation treatment is performed.

As described above, the device of the present invention has a simple structure, is convenient to use, and is capable of integrally realizing separation, shredding, filtration, and mixing and stirring operations for sewage. The cost of use can be reduced, the device of the present invention is excellent in environmental conservation, has high economic efficiency, and is worth pushing and using.

The above is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited to this. Changes and substitutions that come up without the whole creative labor are covered by the protection scope of the present invention. Therefore, the scope of protection of the present invention is based on the scope of protection to which the rights claim is limited.
