Abstract

The invention discloses a fast mud dehydrating device, and is suitable for indoor experiments. The fast mud dehydrating device mainly comprises a mud dehydrating tank, a hydraulic jack and a two-way vacuum suction filtration system; sand cushions with certain thicknesses are arranged on and under the mud in the mud dehydrating tank, and are matched with a geotextile layer, a waterproof top plate and a waterproof bottom plate to form a whole, meanwhile, vacuum suction filtration channels allowing suction filtration pipes to go through are reserved on both the top plate and the bottom plate, thelifting hydraulic jack is arranged under the bottom plate, the mud is then rapidly dehydrated under the co-action of the vacuum negative pressure and the pressure load; a vacuum pump is connected toa liquid collecting barrel with the containing mark through a vacuum pipe in the two-way vacuum suction filtration system, the liquid collecting barrel is additionally provided with two suction filtration pipes, and the two suction filtration pipes are respectively communicated with the vacuum suction filtration channels on the top plate and the bottom plate. The fast mud dehydrating device has the advantages of two-way vacuum prepressing, the load of the external force can be applied, and the dehydrating efficiency is high.

Description

technical field

[0001] The invention relates to the technical field of geotechnical engineering tests, in particular to a quick mud dewatering device. Background technique

[0002] With the continuous acceleration of my country's urbanization process, the construction of civil engineering such as high-rise and super high-rise buildings, expressways, and large bridges has developed rapidly. However, during the construction process, a large amount of construction waste such as waste mud, silt, and muck was generated. Improper disposal will cause environmental pollution and waste of resources, which has attracted great attention from relevant departments and research institutions. Abandoned mud is one of the construction wastes in civil engineering with large volume, serious environmental pollution and difficult disposal.

[0003] Plate and frame filter press is a widely used mechanical dehydration method. Its working principle is that the plate and frame group is compressed b...
