Problems solved by technology

[0005] The technical problem solved by the present invention is that it is necessary to invent a method for manual cleaning of activated sludge in urban sewage treatment plants at the bottom of anaerobic pools, anoxic pools, aerobic pools, and continuous batch pools. The device for pumping bottom sludge can complete the suction of the sludge deposited at the bottom of the sewage treatment plant in a short time without affecting the water volume and quality of the sewage treatment plant, and solve the problem of sludge compaction at the bottom of the biochemical tank. The unsafe factors of artificial dredging at the bottom of the biochemical pool ensure the long-term safe and stable operation of the sewage treatment plant

Embodiment 1

[0039] Such as figure 1 As shown, a device for pumping underwater sludge includes a buoy 1, two flexible connectors 2 (chains), a walking frame 3, a submersible sewage pump 4, four walking wheels 5 (universal wheels ) and a highly adaptive guide rod 6.

[0040] Such as figure 1 , figure 2As shown, when working, fix one end of the sludge conveying pipeline on the outlet of the submersible sewage pump, and fix the other end near the remaining sludge pump or other suitable positions; then hoist the bottom sludge suction device into the biochemical tank to be cleaned, and gradually Loosen the two flexible connectors 2 synchronously until the walking frame 3 has just landed on the bottom of the pool; then re-tighten the flexible connector 2 and fix it on the first lug 19, which is the first lug bolt in the middle of the upper part of the buoy; The nylon rope is symmetrically hung on the lug bolt on the side of the buoy, that is, the third lug 7, and two people pull the nylon ro...

Embodiment 2

[0048] Such as Figure 7-Figure 9 As shown, embodiment 2 also provides a device for sucking bottom sludge, which is basically the same as embodiment 1, the difference is that there are two guide rods 6, and correspondingly the first through hole 8 is also two , respectively located on both sides of the buoy 1.

[0049] The buoy 1 is a cylinder, and on the upper surface of the cylinder, the lines connecting the two first through holes 8 and the two fourth through holes 20 are perpendicular to each other, which can further improve the stability of the device and reduce the rotation of the buoy 1 during the operation of the device .

Abstract

The invention provides a device for pumping water bottle sludge. The device comprises a floating drum which is arranged on the upper part and a walking frame which is arranged on the lower part, wherein a submersible sewage pump is arranged on the walking frame; at least one flexible connecting piece is connected between the walking frame and the floating drum; at least one guide rod is additionally connected between the walking frame and the floating drum; a first through hole is formed in the floating drum; and the at least one guide rod runs through the first through hole, so that the floating drum can slide along a length direction of the at least one guide rod. According to device provided by the invention, it is unnecessary for sewage treatment facilities in a sewage treatment plantto stop running, and the device is applicable to periodical pumping of sludge deposited on water bottom; and the device has the advantages of being short in each pumping time, adjustable in power, high in efficiency, flexible to operate and the like.

Description

technical field [0001] The invention relates to a device for sucking underwater sludge, in particular to a suction device for sludge deposited at the bottom of a sewage treatment plant (station), belonging to the technical field of sewage treatment. Background technique [0002] In the process of rapid urbanization in my country, urban sewage treatment facilities, as one of the important infrastructures of modern cities and towns, play an extremely important role in guaranteeing economic development, production and life of residents, and are essential for improving basic public service capabilities and reducing pollutants. It is of great significance to reduce emissions, build a good ecological environment, and promote sustainable development. As of the end of June 2017, a total of 4,063 sewage treatment plants have been built and operated in cities and towns across the country, with a sewage treatment capacity of 178 million cubic meters per day. It is estimated that by the...
