Description

Technical Field

[0001] The present invention relates to the field of municipal technology, and in particular to municipal environmentally friendly sewage treatment equipment. Background Art

[0002] With the acceleration of urbanization, the urban population continues to increase, and the amount of sewage discharged has also increased sharply. Sewage usually contains floating objects such as paper towels, plastic sheets, fabric fibers, hair, as well as sediments such as mud, stones, and feces.

[0003] In the prior art, the treatment equipment for floating objects and sediments in sewage is generally a sludge pumping device and a floating object scraping device. The sludge pumping device and the floating object scraping device can be used to clean the sediments and floating objects respectively, but two separate devices are required to work independently. Compared with one device that simultaneously cleans both floating objects and sediments, the two separate devices working independently will increase the operating power of the equipment, thereby increasing the energy consumption for cleaning floating objects and sediments, and failing to achieve environmentally friendly treatment of sewage.

[0004] In the prior art, when initially filtering out debris from sewage, the filter will be clogged with debris after being used for a period of time, and the filter needs to be unblocked at this time. When unblocking the filter, automatic unblocking parts or manual unblocking are generally used. During the unblocking process, the debris may be broken, so that the broken debris may pass through the filter into the filtered sewage, increasing the debris content in the sewage, thereby reducing the cleaning efficiency of the sewage. Manual cleaning generally requires the sewage treatment equipment to be stopped before the staff can clean the filter, and the stopping of the sewage treatment equipment will also reduce the treatment efficiency of the sewage.

[0031] Working principle of sewage filtering mechanism 9: sewage is transported from the present invention to filter plate 1 902, and flows into sewage tank 1 through filter plate 1 902 and filter plate 2 903. The filter hole of filter plate 1 902 of the present invention is larger than that of filter plate 2 903. At this time, larger debris in sewage is temporarily stored on filter plate 1 902, and smaller debris is temporarily stored on filter plate 2 903 through filter plate 1 902, and the debris moves to debris storage bin 10 through filter plate 1 902 and filter plate 2 903 due to gravity; When it is necessary to clean the unmoved debris on the filter plate 1 902 and the filter plate 2 903, the electric telescopic rod 2 906 is started to retract, and the electric telescopic rod 2 906 drives the ejection plate 1 909 to move toward the filter plate 2 903 through the transmission connecting rod 907 and the telescopic member 908, and the ejection plate 1 909 drives the ejection plate 2 910 to move toward the filter plate 1 902 through the connecting member 918; When the sliding block 916 is located in the parallel groove 1 912, the ejection plate 1 909 and the ejection plate 2 910 are respectively located below the filter plate 2 903 and the filter plate 1 902; when the sliding block 916 passes through the ejection groove 1 913, the ejection plate 1 909 and the ejection plate 2 910 are both moved upward to block the filter holes on one side of the filter plate 1 902 and the filter plate 2 903. At this time, one side of the filter plate 1 902 and the filter plate 2 903 are both in a flat state, that is, the sewage can wash down the debris on one side of the filter plate 1 902 and the filter plate 2 903; when the sliding block 916 is located in the parallel groove 2 914, The ejector plate 1 909 and the ejector plate 2 910 are still respectively located below the filter plate 2 903 and the filter plate 1 902, but are located at the other side of the filter plate 1 902 and the filter plate 2 903; when the sliding block 916 passes through the ejector slot 2 915, the ejector plate 1 909 and the ejector plate 2 910 are both moved upward to block the filter holes on the other side of the filter plate 1 902 and the filter plate 2 903. At this time, the other side of the filter plate 1 902 and the filter plate 2 903 are both in a flat state, that is, the sewage can flush the debris on the other side of the filter plate 1 902 and the filter plate 2 903 into the debris storage bin 10.

[0032] Combined with Fig. 9 As shown: The debris storage bin 10 includes a bin body 1001 connected to the sewage filtering mechanism 9, a sealing groove 1002 is provided at the bottom of the side end of the bin body 1001, a lower cover plate 1003 is hinged at the bottom, a sealing plate 1004 plugged into the sealing groove 1002 is provided on the lower cover plate 1003, an upper cover plate 1006 is hinged at the top of the bin body 1001, the lower cover plate 1003 and the upper cover plate 1006 are sealed by a sealing strip 1005 located on the lower cover plate 1003, and a locking bolt 1007 is provided on the upper cover plate 1006 to fix the upper cover plate 1006 and the lower cover plate 1003.

[0033] Since the washed down debris contains sewage, the sewage can slowly flow from the bin body 1001 to the sewage tank 1. When the debris in the debris storage bin 10 needs to be cleaned, the locking bolt 1007 is removed and the upper cover 1006 and the lower cover 1003 are opened. At this time, the debris in the bin body 1001 can be cleaned out. Before opening the lower cover 1003, it is possible to observe whether the bin body 1001 contains a large amount of sewage.

[0034] Combined with Figure 1 , Attachment Figure 4 As shown: The driving wheel 4 is divided into two groups, and the solid-liquid separation mechanism 5 includes two driving belts 501 respectively connected between the two groups of driving wheels 4, a plurality of fixed plates 502 are arranged between the two driving belts 501, a plurality of slide bars 503 are arranged on the fixed plates 502, a scraper groove 504 which can scrape off the debris in the sewage tank 1 and temporarily store the debris is arranged on the slide bar 503, a water leakage hole 506 is arranged on the scraper groove 504, a floating block 505 which is slidably connected with the slide bar 503 is arranged between the fixed plate 502 and the scraper groove 504, a slag guide groove 7 located above the driving device 2 is arranged at the front end of the sewage tank 1, a sediment removal mechanism 507 which can push the debris in the scraper groove 504 into the slag guide groove 7 is arranged on the scraper groove 504, and the cleaning mechanism 6 achieves the function of cleaning the debris by driving the sediment removal mechanism 507.

[0035] Working principle of solid-liquid separation mechanism 5: when driving device 2 is started, transmission wheel 4 drives transmission belt 501 to rotate, and several fixed plates 502 of transmission belt 501 move. When fixed plate 502 is located in sewage, slag guide groove 7 contacts with sewage groove 1 and can drive the debris at the bottom of sewage groove 1 to move with slag guide groove 7. When fixed plate 502 is located on sewage, the debris moving with slag guide groove 7 can gradually move into slag guide groove 7. Since floating block 505 slides on slide bar 1 503, floating block 505 is located on sewage at this time, and floating block 505 can drive the debris floating on sewage to move to floating object absorption device 8 during the movement of fixed plate 502, and the floating object absorption device 8 cleans the floating objects. Floating object absorption device 8 is prior art, mainly composed of water suction pump, water suction head and water outlet pipe. Water suction pump can suck out floating objects on sewage through water suction head.

The cleaning mechanism 6 pushes the block 2 509 to move in the scraper groove 504 so that the debris in the scraper groove 504 is pushed to the slag guide groove 7.

[0037] Working principle of cleaning mechanism 6: when scraper groove 504 contacts contact plate 609, contact plate 609 is pulled by spring 2 604 so as not to rotate, and electric telescopic rod 1 606 is started to extend, and electric telescopic rod 1 606 drives ejection end 607 to move to contact block 2 509 and drives block 2 509 to move into scraper groove 504, and block 2 509 drives block 1 508 to move to one side of slag guide groove 7 through connecting rod 510, and at this time, block 2 509 can push the debris in scraper groove 504 into slag guide groove 7, and when block 2 509 moves, block 2 509 drives moving block 513 to move toward fixed block 511, and at this time, spring 1 514 is compressed, and when electric telescopic rod 1 606 contracts, spring 1 514 can drive moving block 513 to reset, and moving block 513 drives block 2 509 to reset; During the process, the scraper groove 504 drives the slider 603 to move toward the side of the spring 2 604 through the contact plate 609. At this time, the spring 2 604 is compressed. In the process of the slider 603 moving toward the side of the spring 2 604, the spring 1 514 has limited tensile strength before deformation, that is, the slider 603 is inserted into the scraper groove 504 by the electric telescopic rod 1 606 and moves with the scraper groove 504. When the ejection end 607 is separated from the block 2 509, the spring 1 514 is stretched to a certain extent under the rotation of the rotating member 608 driven by the contact plate 609 and then reset.
