Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1 and 2, the sludge-water separation device for filtering type domestic sewage treatment comprises a solid-liquid separation tank 6 and a clean water tank 7. The solid-liquid separation tank is provided with a water inlet 14. The solid-liquid separation tank is provided with a sludge pump 15 to return sludge to the pre-denitration tank. The clean water tank is provided with a clean water pump 17 for outputting clean water. A roller 64 and a roller driving mechanism 65 for driving the roller to roll are provided in the solid-liquid separation tank. The circumferential surface of the roller is provided with water holes for the roller part. The end surface 81 of the drum is of a closed structure. The drum is covered with a filter membrane 66 covering the water through holes of the drum. The filtering membrane is sleeved on the roller. A dirt scraping rod 67 which is abutted with the filtering membrane and extends along the axial direction of the roller is arranged in the solid-liquid separation tank. The water inlet 14 is located above the drum. A vertical inlet tube 68 is connected in the inlet. The water inlet pipe is a blind pipe with the lower end closed. The vertical inlet pipe is provided with a number of radially extending inlet branches 69 distributed circumferentially along the inlet pipe. The water inlet branch pipe is provided with a water inlet hole 70. The water inlet holes are only positioned on the end surface of the water inlet branch pipe. The roller driving mechanism comprises a roller driving shaft arranged in the roller in a penetrating way and a roller motor 72 for driving the roller driving shaft to rotate 71. The drum drive shaft extends in a horizontal direction. The solid-liquid separation tank and the clear water tank are distributed along the horizontal direction. Two ends of the roller driving shaft are rotatably connected to the wall of the sewage pool. The roller driving motor is positioned outside the solid-liquid separation tank. The roller driving motor is connected with one end of the driving shaft and the other end of the roller driving shaft extends into the clean water tank. A clear water flow passage 73 is provided in the drum driving shaft. The clear water flow passage is communicated with the end surface of the roller driving shaft at one end of the clear water tank. The clear water flow passage is communicated with the inner space of the roller through the rotating shaft part water inlet hole 74.

When the device is used, under the filtration of the filtering membrane, clean water in the solid-liquid separation tank enters the roller, sludge is retained on the filtering membrane and falls to the bottom of the tank, and the clean water enters the clean water flow channel through the water inlet hole of the rotating shaft part and finally flows into the clean water tank. The roller motor drives the roller to roll, so that the sludge on the filtering membrane is scraped by the sludge scraping rod.

The scraping strip driving mechanism comprises a scraping strip stroke detection switch 75, a control unit, two fixed pulleys 76, a guy cable 77 with one end connected with the horizontal scraping strip and a water receiving tank 78 which is connected with the other end of the guy cable, is positioned in the clear water pool and can collect water flowing out of the clear water flow channel. The upper end of the vertical sliding groove is provided with a horizontal scraping strip ascending stroke limiting block 79 for preventing the horizontal scraping strip from ascending. The water receiving tank is provided with an electric water outlet valve 80. The inhaul cable is supported on the fixed pulley. The weight of the horizontal scraping strip is larger than that of the water receiving tank, namely the horizontal scraping strip can descend by means of self weight to drive the water receiving tank to ascend. The weight of the water receiving tank when filled with water is larger than that of the horizontal scraping strip, and the water receiving tank can overcome the weight of the horizontal scraping strip to generate descending when filled with water, and the horizontal scraping strip is driven to ascend as a result of the descending. When the contact of the stroke of the scraping strip is detected, the control unit enables the electric water outlet valve to be opened for a first set time and then closed when the horizontal scraping strip rises to the stroke end, the horizontal scraping strip is instantly descended when the electric water outlet valve is opened, and after the horizontal scraping strip is descended to the lower limit position, the electric water outlet valve is kept opened for a second set time and then closed. The electric water outlet valve is opened, so that the water receiving tank can be lifted up after the time is long. The first set time period in this embodiment is the time for the horizontal wiper strip to descend from the upper end of travel to the lower end of travel plus the second set time period.
