The central cover 3-18 is located directly below the flip cover 3-5.

[0029] In the present embodiment, in order to achieve the effect of fully removing impurities and convenient cleaning and maintenance, an impurity removal and cleaning component 3 is designed. Support columns 3-1 are fixed on the surfaces of the two impurity removal tanks 1. A connection block is arranged on the support column 3-1. A rotating shaft 3-3 is rotatably connected between the two connecting blocks 3-2. Flip covers 3-5 are fixed on the outer two end surfaces of the rotating shaft 3-3. The flip cover 3-5 can be docked between the impurity removal tanks 1. Circular grooves 3-6 are provided on both surfaces of the flip cover 3-5.

Two flip covers 3-5 are arranged, which can be switched by rotating the rotating shaft 3-3. When cleaning is needed, the flip cover 3-5 to be cleaned can be switched with the clean flip cover 3-5, which does not affect the normal impurity removal and can be cleaned and maintained in a delicate manner. An extension frame 3-17 is fixed at the lower end of the support column 3-1 at the bottom. A central cover 3-18 is arranged at one end of the extension frame 3-17 to collect the cleaned impurities for centralized treatment.

[0030] Furthermore, the inner surface of the circular groove 3-6 is an inclined structural surface all around.

[0031] In this embodiment, the inclined surface on the inner side of the circular groove 3-6 facilitates the material to be concentrated in the filter hole 3-7 for processing and is convenient for cleaning.

The incoming materials are filtered through the filter holes 3-7, and the filtered waste residues are concentrated in the circular groove 3-6. When there is too much accumulation and needs to be cleaned, pull the fixed column 3-13 through the pull rod 3-16, pull it out in the slot 3-10, and then push the flip cover 3-5, rotate it through the rotating shaft 3-3, switch the clean flip cover 3-5, after the replacement, insert the fixed column 3-13 into the slot 3-10 on the surface of the clean flip cover 3-5, turn the flip cover 3-5 that needs to be cleaned downward 180°, and then rinse and clean the filter holes 3-7 in the flip cover 3-5, and the cleaned impurities fall into the collecting cover 3-18 for collection and cleaning.
