The invention relates to the technical field of wastewater treatment devices, and discloses a wastewater filtering and purifying treatment device. The wastewater filtering and purifying treatment device comprises a filtering box. Two sides of the top of the filtering box are fixedly connected with support plates. The top ends of the two support plates are moveably sleeved with a rotation shaft. Two ends of the rotation shaft are fixedly sleeved with a reel positioned between the two support plates. The top of the side face of one of the support plates is fixedly connected with a supporting plate. The top of the supporting plate is fixedly provided with a driving motor. An output shaft of the driving motor is fixedly connected with one end of the rotation shaft. The top of the filtering boxis fixedly connected with a vertical plate. The wastewater filtering and purifying treatment device is capable of, through enabling a filter screen to cross a port at the bottom of a filtering watertank, in a process of filtering wastewater, rotating a rolling shaft so that a new filter screen is moved to the port of the filtering water tank, thereby preventing garbage in the wastewater from blocking the filter screen in a continuous filtering process of the wastewater, ensuring that the wastewater is normally filtered, and improving filtering efficiency of the wastewater.

The present invention discloses a feeding device in an unloading centrifuge, which can make a suspension distribute evenly along a circumference of a small end of a rotary drum. The present invention comprises a machine shell. A rotating principal axis is arranged in the machine shell and is equipped with the rotary drum. The external side of the bottom of the drum is concave inwards to form a material silo. The bottom of the material silo communicates with a plurality of material holes evenly arranged on the same circumference at the bottom of the drum. The interior wall of the machine shellis equipped with a material discharge hopper cooperating with the material silo, and the material discharge hopper communicates with a plurality of feed pipes going through the machine shell. The feeding device of the present invention can make the centrifuge operate smoothly in the working course, so as to ensure the normal operation of filtering, spinning, unloading and other courses of the centrifuge and reduce the mechanical problems greatly.

The invention discloses a sewer pipe filtering device. The technical scheme is characterized in that the sewer pipe filtering device comprises an upper connecting seat and a lower connecting seat which are connected with a sewer pipe, wherein a filtering unit is arranged between the upper connecting seat and the lower connecting seat and comprises a first connecting shaft horizontally and rotationally connected to the side wall of the lower connecting seat, a second connecting shaft rotationally connected to the side wall of one side, away from the first connecting shaft, of the lower connecting seat, a filter net, a sleeve glidingly connected to the upper connecting seat in the vertical direction, a rubber ring fixedly connected to the lower end surface of the sleeve and butted against the filter net as well as a spring nested on the upper connecting seat and pushing the sleeve to move downwards, one end of the filter net winds around the first connecting shaft, the other end of the filter net winds around the second connecting shaft, and a driving mechanism driving the second connecting shaft to rotate is arranged between the sleeve and the second connecting shaft. By means of the scheme, the filter net can be unchoked without dismounting the upper connecting seat and the lower connecting seat, and blocking of the filter net is prevented.

The invention provides a dish-washing machine convenient to clean. A residue collector is made to detachably stretch into a lifting cup to be fixed by making a via hole used for installing the residue collector formed in the side of the lifting cup; on one hand, the residue collector and the lifting cup are made to form two parts respectively, the structural complexity of the lifting cup body and a mold is simplified, and machine shaping is conducted conveniently; on the other hand, the residue collector can be installed in the lifting cup, the residue collecting efficiency is not affected, and the residue collector can be removed from the lifting cup to make cleaning work of the residue collector and the lifting cup convenient to operate, so that the residue collector is detachable in two directions of the lifting direction, facing the lifting cup relative to a circulating water cup, of the residue collector and the lifting cup side direction. A fine filter screen is located on the periphery of the residue collector, secondary filtration is conducted on circulating washing water flowing out of the residue collector so as to further improve the cleanliness of the circulating washing water, and the filtering effect is improved conveniently.
