[0021] Combine the following Figures 1 to 7 The invention describes an environmentally friendly sludge treatment and recovery integrated equipment and method.

[0022] In one embodiment, an environmentally friendly sludge treatment and recycling integrated device includes a treatment channel 100, a diverter 200, a water circulation component 300, a lifting component 500, a transfer component 600 and a push component 700; a plurality of lifting areas 140 and a plurality of flow areas are arranged in a linear direction inside the treatment channel 100, and the plurality of lifting areas 140 and the plurality of flow areas are arranged crosswise; the diverter 200 is located in the flow area for diverting sewage; the water circulation component 300 is installed outside the treatment channel 100 for diverting sewage in the lifting area 140 The liquid is drawn in and pumped to the flow area, and the surface of the diverter 200 is flushed; the lifting member 500 is vertically installed in the lifting area 140, and is used to filter large particles in the sewage; the transfer member 600 is installed at the connection between the lifting area 140 and the flow area, and is connected to the lifting member 500. When the lifting member 500 rises, the lifting area 140 and the flow area are separated, and when the lifting member 500 descends, the lifting area 140 and the flow area are connected; the pushing member 700 is installed above the diverter 200, and the pushing member 700 can move in the horizontal direction.

[0023] Specifically, when the sewage flows through the treatment channel 100, the water circulation component 300 pumps the sewage from the lifting area 140 to the flow area. During the pumping process, the sewage will flow through the lifting member 500, and the lifting member 500 will filter the pumped sewage to filter out the large particles of impurities. The sewage pumped to the flow area will flush the surface of the diverter 200 to prevent the sludge in the sewage from precipitating and adhering, so that the surface of the diverter 200 is always kept clean.

During the lifting process of the lifting member 500, the transfer member 600 is affected by the lifting of the lifting member 500, thereby separating or canceling the separation between the lifting area 140 and the flow area.

[0024] In the above-mentioned environmental sludge treatment and recycling integrated equipment, when the sewage flows through the treatment channel 100, the water circulation component 300 pumps the sewage from the lifting area 140 to the flow area. During the pumping process, the sewage will flow through the lifting member 500, and the lifting member 500 will filter the pumped sewage to filter out the large particles of impurities. The sewage pumped to the flow area will flush the surface of the diverter 200 to prevent the sludge in the sewage from precipitating and adhering, so that the surface of the diverter 200 is always kept clean. Then the pusher 700 will push the sewage so that the small particles of impurities it carries are pushed to the lifting area 140. During the lifting process of the lifting member 500, the transfer member 600 is affected by the lifting of the lifting member 500, thereby isolating or canceling the separation between the lifting area 140 and the flow area. The equipment can remove large particles of impurities in sewage and sludge, thereby indirectly improving the sludge processing effect. At the same time, due to the reduction of large particles of impurities in the sludge, it can also prevent the phenomenon of material blockage during subsequent environmental protection treatment.

The partitions 130 divide the interior of the processing channel 100 into a lifting area 140 and a flow area. A water inlet and outlet 131 is opened at the bottom end of the partition 130. The water inlet and outlet 131 is used to connect the lifting area 140 and the flow area.

[0026] Specifically, the lifting area 140 and the flow area are arranged at intervals, the interval between two lifting areas 140 is the flow area, the interval between two flow areas is the lifting area 140, and the lifting area 140 and the flow area are connected to each other.

[0031] The top of the triangular block 720 is used to divert and guide sewage and sludge, and the first push plate 730 is used to push the sewage and sludge in the diversion channel 210. The power generated during the pushing process drives the sewage and sludge in the flow area to enter the lifting area 140 for filtration treatment. Since the second push plate 740 is an arc-shaped plate structure, when the triangular block 720 moves along the length direction of the guide rail 710, it is affected by the arc surface of the upper surface of the diversion block. The second push plate 740 will fit and scrape the upper surface of the diversion block to prevent the sludge from adhering to the surface of the diversion block.

[0035] Specifically, a guard plate 150 is provided on one side of the partition 130 of the flow zone, and a clamping area 151 is formed between the guard plate 150 and the partition 130. The transfer member 600 includes a transfer wheel group 610, a transfer belt 620, a first clamping plate 630 and a second clamping plate 640; the transfer wheel group 610 is arranged at the top of the partition 130, and the two ends of the first clamping plate 630 are respectively clamped in the two clamping areas 151, and the top of the second clamping plate 640 is connected to the bottom end of the first clamping plate 630, and the two ends of the transfer belt 620 are respectively connected to the first clamping plate 630 and the longitudinal filter 520.

[0037] The sewage pumped to the flow area will flush the surface of the diverter 200 , and then the pusher 700 will push the sewage so that the small particles of impurities it carries are pushed toward the lifting area 140 .

[0038] During the lifting process of the lifting member 500 , the transfer member 600 is affected by the lifting and lowering of the lifting member 500 , thereby partitioning or canceling the partition between the lifting area 140 and the flow area.

[0039] In the treatment method of the above-mentioned environmental sludge treatment and recycling integrated equipment, when the sewage flows through the treatment channel 100, the water circulation component 300 pumps the sewage from the lifting area 140 to the flow area. During the pumping process, the sewage will flow through the lifting member 500, and the lifting member 500 will filter the pumped sewage to filter out the large particles of impurities.
