Description

Fixed disc filtering device with efficient sludge removal function

Technical Field

The utility model relates to a sewage treatment device field especially relates to a fixed disk filter equipment with high-efficient desilt function.

Background

The biological rotating disc is a biological membrane method waste water treatment technology, and microorganisms with longer survival time can grow on the biological rotating disc, so that the biological rotating disc has longer impact load resistance and good treatment effect. The biological disc has the advantages of high microorganism concentration, no need of sludge backflow, low operation cost and the like in the aspects of process and maintenance operation, so that the biological rotating disc is widely used for treating sewage. Although the water treatment technology is widely applied, the prior art has many disadvantages, for example, the concentration of suspended matters in the water after the water is treated in the biological rotating disc before the water enters the next filtering device is lower than 30mg/L, otherwise, the filtering device is easy to block, and the concentration of the water after the water is treated by the biological rotating disc is generally higher than the number, so that the prior art needs to add a sedimentation tank to precipitate the suspended matters in the water before the water enters the filtering device, which inevitably causes great increase of occupied space, time and labor waste, and in addition, the filtering form of the prior filtering device generally adopts a rotating disc rotating form, so that the energy consumption is high, and the operation cost is high.

Therefore, a fixed disc filtering device integrated with the biological rotating disc device is added on the biological rotating disc device by the technical personnel in the field, for example, the biological rotating disc and fixed disc filtering integrated device with the authorization notice number of CN206126936U comprises a biological rotating disc and a fixed disc filtering device, and the biological rotating disc and the fixed disc filtering device are connected through a communicating pipe; the fixed disc filtering device comprises a disc, a mud sucking mechanism, a driving device II, a support and a liquid level limiter, the disc is fixed on the support, the driving device II is connected with the mud sucking mechanism, the liquid level limiter is fixed on a groove body, filter cloth is wrapped outside the disc, water treated by the biological rotating disc enters the fixed disc filtering device through a communicating pipe, the water pressure inside and outside the disc is different, the water flows into the disc through the filter cloth and then enters the support from the disc to be discharged out of the fixed disc filtering device, when excessive sludge is adsorbed outside the filter cloth, the water speed flowing into the disc is smaller and smaller, so that the water level outside the fixed disc filtering device is increased, when the water is increased to the liquid level limiter, the driving device II, a cleaning valve and a mud discharging valve are automatically opened through a control cabinet, the driving device II drives a rotating shaft to rotate, the rotating shaft drives the mud sucking device to rotate, at the moment, the sludge on the surface of the filter cloth is sucked into an opening in the middle of a scraper plate through backwashing, flows into the rotating shaft through the connecting hose and finally flows out of the cleaning pipe, and the sludge at the bottom of the tank body is directly discharged from the sludge discharge pipe. However, the opening of inhaling mud of this patent is opened in the centre of scraper blade, and when the disc was scraped to the scraper blade, the real most of mud on the disc was pasted on the soil pick-up pipe, and the opening on the scraper blade can not play fine soil pick-up effect, and later mud can continue to remain in the fixed plate filter equipment.
