Selection device of flocculating agent for engineering slurry filter-pressing dehydration treatment

Abstract

The invention relates to a selection device of a flocculating agent for engineering slurry filter-pressing dehydration treatment. The device comprises a base, a semi-sealed cylinder arranged above the base, and a cover arranged on the opening side of the semi-sealed cylinder, and a stirring device is arranged at the bottom of the semi-sealed cylinder. The cover is provided with a mud inlet pipe, an adding pipe for adding the flocculating agent, an air inlet pipe for inflating and pressurizing the semi-sealed cylinder and a drainage observation device. The drainage observation device comprises a mud filling pipe and a drainage pipe, wherein mud in the semi-sealed cylinder is pressed to enter the mud filling pipe, one end of the mud filling pipe extends into the semi-sealed cylinder after being inserted into the cover, and the other end of the mud filling pipe is provided with a sealing wall; a permeable stone is arranged on the inner side of the sealing wall; a round hole for water to penetrate through is formed in the sealing wall; and the drainage pipe is communicated with the mud filling pipe through the round hole. According to the selection device for the flocculating agent used for the engineering slurry filter-pressing dehydration treatment, the required flocculating agent can be quickly and accurately selected by observing the liquid level height at the side of the drainage pipe, so that the labor hour is saved, and the manpower is saved.

Description

【Technical field】 [0001] The invention relates to a dehydration treatment device, in particular to a selection device for flocculants used in engineering mud filter press dehydration treatment. 【Background technique】 [0002] With the vigorous advancement of the urban process and the construction of ecological civilization, engineering projects such as new construction and widening of port channels and lake dredging have also been carried out one after another. The dredged silt generated by this is as huge as billions of cubic meters every year. There will also be a large amount of engineering mud that has nowhere to be placed in construction (hereinafter, dredging mud and engineering mud are collectively referred to as ultra-high moisture content slurry), and the terminal disposal of huge amounts of ultra-high moisture content slurry has been plagued by engineering circles. At present, for the treatment of ultra-high water content sludge, there is dehydration and reduction ...

AI Technical Summary

Problems solved by technology

There are two major deficiencies in the beaker test: (1) inaccurate, when the water content in the mud is small, the mud-water interface is not obvious, and it is difficult to distinguish whether the effect is good or bad; (2) the mud is in a state of dead weight in the beaker test, which means Contrary to the load regime of a plate and frame filter press
