Description
Technical Field

Background
During the dredging process of river and lake bottom mud, a large amount of dredging mud is often generated, and dehydration reduction is needed for reducing subsequent outward transportation pressure or facilitating resource treatment. Meanwhile, the slurry plate-and-frame dehydration and drying technology is increasingly widely applied to the dewatering and reducing engineering of the dredged slurry due to the characteristics of high dehydration efficiency, obvious reducing effect, high mechanization degree and the like.
Due to the influence of economic activities such as land building in a surrounding lake, fishpond building and feed throwing, weeds at the bottom of a general urban river or lake are clustered, bottom mud is seriously eutrophicated, the flowability is poor, the garbage content is high, and the types of the weeds are various, such as building garbage, cultivation waste, stones, shells and the like. For the plate-frame dehydration and drying process of river and lake dredging slurry, the influence of garbage in the bottom sludge on the whole process is great, such as blockage of a feed pump, puncture of filter cloth and the like, and the direct relation is that whether the whole production line can normally operate or not, so that impurity removal needs to be carried out on the slurry before the plate-frame dehydration and drying process of the slurry.
At present, an actual impurity removal system of an engineering is mainly formed by directly building an impurity removal pool on a construction site, a grating machine is arranged in the middle of the impurity removal pool, and the rotation of the grating machine is utilized to remove garbage in slurry. Firstly, for example, when garbage generated in the impurity removal process of the grating machine enters a garbage groove at the top of the grating machine, the garbage needs to be manually and timely transferred out of a pool, the mechanical degree of the whole process is low, and the construction efficiency is low; secondly, because the whole impurity removal process is open, the garbage is directly exposed in the impurity removal process and is easy to emit peculiar smell, so that the engineering image and the surrounding environment are influenced; in addition, the smallest impurity removal size of the common grid is 5mm, garbage below 5mm cannot be treated, and great potential safety hazards are brought to the operation of subsequent plate frame dehydration. Meanwhile, due to the lack of timely monitoring and effective control measures for the slurry liquid level in the tank, the slurry liquid level in the tank exceeds a safety warning line due to the fact that the slurry inlet flow is too large, and even overflows from the top of the tank, and therefore potential safety hazards are generated.
