Description

Peripheral transmission sludge thickener device

Technical Field

The utility model relates to a sewage treatment device, in particular to a peripheral transmission sludge concentrator device.

Background

The circular amplitude-flow type concentration sedimentation tank is generally adopted by large and medium-sized sewage treatment plants as an important treatment facility. The peripheral transmission sludge thickener device is suitable for treating primary sludge in a circular amplitude flow type concentration sedimentation tank in water treatment engineering. The machine can not only meet the sludge scraping function, but also play a role in stirring slowly, and improve the sludge concentration effect.

The peripheral transmission sludge thickener device has the working principle that: sewage enters the flow stabilizing tank through a water inlet channel in the support column of the concrete flow stabilizing tank and continuously flows around the concentration sedimentation tank after passing through the flow stabilizing cylinder. In the process, the peripheral transmission sludge thickener device drives the working bridge to rotate around the center of the slewing bearing component through the slewing drive component, so as to drive the thickening grid bars and the mud scraping plates to rotate, so that the sludge settled at the bottom of the thickening sedimentation tank is scraped and collected in a sludge hopper at the center of the tank, then the sludge is discharged out of the sedimentation tank through the sludge discharge pipe, and the supernatant flows out of the sedimentation tank through the water outlet groove and the water outlet pipe.

In the working process of the peripheral transmission sludge thickener, the sludge scraping device is an important component of the peripheral transmission sludge thickener, and the quality of the structure of the sludge scraping device is directly related to whether the sludge scraping effect of the equipment is efficient and stable.

As shown in fig. 4, the scraper 6 in the original peripheral transmission sludge thickener apparatus is connected to a scraper support 11 through a pin 17, the scraper 6 can rotate up and down around the pin 17, then one end of a plurality of steel wire ropes 13 is connected to a boom lifting lug 14 at the upper end of the scraper, and the other end is connected to a boom lifting lug 12 at the lower bridge support, so that the scraper 6 is suspended and hung above the conical tank bottom surface of the thickening sedimentation tank 161, and a fixed gap (generally 10 mm) is formed between the lower edge of the scraper 6 and the conical tank bottom surface of the thickening sedimentation tank 161. However, in the working process of the thickener, the slope of the conical Chi Demian of the concentration sedimentation tank 161 is large or small due to civil engineering pouring errors, so that the size of the gap between the lower edge of the mud scraper 6 and the bottom surface of the conical tank of the concentration sedimentation tank 161 can be changed directly, the mud scraper 6 cannot scrape away the mud on the conical Chi Demian of the concentration sedimentation tank 161 well, the mud is too thick in the place with large gap, and the mud can float out of the water surface after a long time and flow out of the tank along with clean water, so that the quality of effluent water is influenced. In places with small gaps, the sludge is too clean and has no sludge residue, which can affect the subsequent sludge sedimentation, and even more, the friction between the sludge scraping plate 6 and the conical Chi Demian of the concentration sedimentation tank 161 causes the damage of the sludge scraping plate 6, thereby greatly affecting the production efficiency and the effluent quality of the sewage treatment plant.
