Periphery drive sludge scraping and sucking machine

Abstract

The invention discloses a periphery drive sludge scraping and sucking machine. The two ends of a straight drum are provided with large end cover shafts respectively, one end of one large end cover shaft is provided with a conical drum, one end of the other large end cover shaft is sleeved with a labyrinth ring and connected with a large universal joint, the other end of the universal joint is connected with a planetary gear differential mechanism sleeved with a right bearing on a fixing base, the other end of the planetary gear differential mechanism is connected with a main belt pulley, one end of the conical drum is connected with a small end cover shaft, the small end cover shaft is sleeved with a left bearing, the surface of the small end cover shaft is provided with a liquid outlet, a solid material box is arranged below the small end cover shaft, the large end cover shaft at the other end is provided with a liquid outlet, a liquid material box is arranged below the large end cover shaft at the other end, a through cavity is formed in the small end cover shaft, the conical drum, the straight drum and the large end cover shafts, and a spiral barrel is arranged in the cavity. Thus, according to the periphery drive sludge scraping and sucking machine, adjustment can be carried out based on the water content, viscosity and the like of treated materials.

Description

technical field [0001] The invention relates to a peripheral transmission mud scraper and suction machine. Background technique [0002] The peripheral transmission scraper and suction dredger is mainly composed of a scum skimmer, a scum scraper and a slag discharge bucket. The generated transverse force pushes the scum to the side of the pool, and the scraping rake is used as an extension of the scum board, and is overlapped with the scum board by the sealing plate, and when the suction dredge moves to the slag discharge hopper, the scum is removed It is scraped into the bucket and discharged out of the pool by gravity. However, since the water level difference between the liquid level of the sedimentation tank and the sludge collecting tank of the mud scraper is only 300 mm, the actual pressure difference is low, and the sludge fluidity is poor, resulting in longer sludge residence time in the sedimentation tank and worse sludge activity. The efficiency of biochemical tr...

Problems solved by technology

However, since the water level difference between the liquid level of the sedimentation tank and the sludge collecting tank of the mud scraper is only 300 mm, the actual pressure difference is low, and the sludge fluidity is poor, resulting in longer sludge residence time in the sedimentation tank and worse sludge activity. The efficiency of biochemical treatment is reduced, and the lifting mixture contains less mud

At the same time, the slag scraping and mud scraping of the existing scraper and suction machine are set separately, resulting in a small processing capacity at one time, and the increased floor space of multiple devices. At the same time, the simultaneous operation of multiple devices consumes a lot of energy, and it needs If the sludge is sucked later, the concentration of the discharged activated sludge is low, and the sludge discharge effect is poor.
