[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 As shown, the novel wastewater pretreatment device in this example includes a housing 1, a filter cartridge, and a drive mechanism 3. The housing is typically rectangular, and the drive mechanism is typically a motor. An inlet 2 is installed on the left side of the housing 1, and the drive mechanism 3 is installed on the right side. The filter cartridge is installed in the upper part of the chamber of the housing 1. The filter cartridge includes a cylinder 4, the left end of which is rotatably connected to the housing wall via bearings, etc. Filter holes 5 are spaced apart on the circumferential wall of the cylinder 4, and spiral blades 6 are fixed on the inner wall of the cylinder 4. The drive mechanism 3 drives the filter cartridge to rotate. The outlet end of the inlet 2 is connected to the cylinder cavity of the cylinder 4. Wastewater and other wastewater enter the cylinder through the inlet. During the rotation of the cylinder 4, the water is discharged from the filter holes, and the filtered impurities are driven forward by the spiral blades and finally extend out from the right end of the cylinder.

[0021] A partition 12 is fixed at the bottom wall of the chamber 1, and the area below the filter cartridge is divided into a left chamber and a right chamber by the partition 12. The right outlet end (i.e. the cartridge opening) of the filter cartridge is located above the right chamber. A discharge port 14 is installed at the bottom wall of the right chamber, and the filtered impurities are discharged from the discharge port.

[0022] To avoid the connection between the drive mechanism and the cylinder affecting the discharge of impurities, in this example, the output end of the drive mechanism 3 is connected to the end of the cylinder 4 through a connecting mechanism. Specifically, the connecting mechanism includes a turntable 17 and a connecting rod 18. The turntable 17 is fixed to the output end of the drive mechanism 3, and the connecting rod 18 is fixed around the center of the turntable 17. The other end of the connecting rod 18 is fixed to the end of the cylinder. Impurities discharged from the cylinder can fall directly through the gap between the connecting rods.

[0023] A stirring mechanism is installed in the left chamber, located below the filter cartridge. The stirring mechanism includes a first shaft 7, a second shaft 8, and blades 9. The first shaft 7 and the second shaft 8 are slidably connected, and the blades 9 are fixed at intervals on the first shaft 7. An opening is formed at the end of the first shaft 7 corresponding to the cavity wall, and a fixing plate 16 is detachably installed at this opening, such as by bolts. The first shaft 7 and the fixing plate 16 are rotatably connected by bearings.

[0024] The second shaft 8 is rotatably connected to the partition plate 12 via bearings, etc. The end of the second shaft 8 extends into the right chamber and is connected to the filter cylinder through the transmission mechanism 13. If the transmission mechanism is a transmission gear type, one gear is sleeved at the end of the second shaft 8 and the other gear meshing with it is sleeved on the cylinder 4. When the cylinder rotates, the stirring mechanism starts synchronously.

[0025] An orifice 15 for inputting liquid medicine is formed on the side wall of the left chamber. When in use, the water discharged from the cylinder 4 falls into the left chamber, and flocculant, etc. are input through the orifice. The first shaft 7 and the second shaft 8 stir to fully flocculate, and the flocculated material sinks.

[0026] In this example, the bottom wall of the left chamber is sloping. A drain outlet 10 is formed at the high end of the bottom wall of the left chamber, and a material discharge outlet 11 is formed at the low end. The liquid flows out from the drain outlet, and the flocculated material is discharged from the material discharge outlet. Valves are installed at both the drain outlet and the material discharge outlet.

[0027] When in use, wastewater is fed into the filter cartridge. During the rotation of the filter cartridge, the water is discharged from the filter holes, while the remaining impurities are discharged from the end of the filter cartridge. The discharged water falls into the left chamber where the stirring mechanism is located. Flocculant and other chemicals are fed into the filter cartridge through the orifice. The flocculation process takes place during the stirring process. The fixed plate can be removed and the first shaft can be pulled out to facilitate the cleaning of the flocculent material on the blades. The operation is convenient and the functions are diversified.

[0028] For the sliding keyway between the first shaft and the second shaft, if the end of the second shaft 8 is formed with a rectangular column and the corresponding end of the first shaft 7 is formed with a rectangular hole, the rectangular column extends into the rectangular hole to form a sliding keyway. The first shaft 7 and the second shaft 8 can rotate synchronously, and the first shaft can be pulled out for easy cleaning.

[0029] In this example, a liquid distribution box 19 is fixed on the top wall of the box 1, and a liquid outlet hole 20 is formed on the corresponding top wall of the box. The liquid outlet hole connects the liquid distribution box chamber with the chamber above the filter cartridge, allowing high-pressure water to be filled into the liquid distribution box. Then, the filter holes are rinsed with water for easy cleaning.

[0030] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
