Problems solved by technology

However, when the existing geotechnical bag is used for dehydration, the dewatered water lacks collection and centralized treatment. Generally, the on-site conditions are used to discharge it back to the water body, which is easy to cause pollution. In addition, natural infiltration and mud self-gravity are used to complete the extrusion dehydration during dehydration, and the extrusion effect is insufficient. Good, the dehydration efficiency is low, and the time is long. When using soil or stones for counterweight extrusion, due to the huge amount of mud, the volume of the dehydration bag is too large, and there are difficulties in on-site operation.

Embodiment 1

[0015] like figure 1 As shown, the dehydration box 1 is placed on a flat and relatively hard ground or platform, and the seepage pool 13 is formed between the platform brackets arranged at the bottom of the dehydration box 1, and the dehydration bag 2 is placed on the bracket 6 at the bottom of the box body 1, and then Put the hydraulic bag 3 flat on the dehydration bag 2, then connect the mud injection port 5 of the dehydration bag, and pass the pipeline and the water pump 4 between the water injection port 11 of the hydraulic bag and the water outlet 10 of the seepage tank 13 connect. When working, first inject the slurry to be dehydrated into the dewatering bag 2 through the mud injection port 5, and during the pouring process, water will continuously escape into the seepage pool 13 at the bottom of the box body 1, and start the water pump 4 to collect this part of the dehydrated water from the water outlet 10 And inject it into the water pressure bag 3 through the water i...

Embodiment 2

[0017] like figure 2 As shown, the dehydration box is placed on a flat and relatively hard ground or platform, and the seepage pool 13 is formed between the partitions arranged at the bottom of the dehydration box 1, and the dehydration bag 2 is placed on the partition 7 at the bottom of the box body 1, and then Put the hydraulic bag 3 flat on the dehydration bag 2, then connect the mud injection port 5 of the dehydration bag, and pass the pipeline and the water pump 4 between the water injection port 11 of the hydraulic bag and the water outlet 10 of the seepage tank 13 connect. Connect dehydration agent 8 (polyferric sulfate, etc.) to the mud injection pipeline, and connect water purification agent 9 (polyaluminum chloride, etc.) to the pipeline at the rear end of the water pump. When working, first inject the mud to be mixed with dehydrating agent into the dehydration bag 2 through the mud injection port 5, during the pouring process, water will continuously escape into t...

Abstract

The invention relates to a hydraulic geotextile bag dewatering box. A water seepage tank is formed among platform brackets or separator plates arranged on the bottom layer of the dewatering box; a dewatering bag is flat laid on the platform brackets or the separator plates; a hydraulic bag is flat laid on the dewatering bag; a mud injection opening is formed in the dewatering bag; a water inlet is formed in the hydraulic bag; a water outlet is formed in the water seepage tank; the water inlet of the hydraulic bag is connected with the water outlet of the water seepage tank through a pipe and a water pump. The dewatering box can complete the dewatering process on the water desilting site, and can effectively solve the transport and subsequent disposal problems caused by high moisture content of sludge. According to the invention, the dewatering effect of the geotextile bag is strengthened by using the dewatering box body and the hydraulic function, and the equipment structure and dewatering process are described; the method and equipment can effectively improve the dewatering efficiency of the geotextile bag, reduce the operation time, effectively improve the quality of separated water, and reduce the secondary pollution; the equipment can also be used for dewatering sewage sludge, building mud, bean dregs and other materials.

Description

technical field [0001] The invention belongs to a sludge dewatering device, in particular to a hydraulic geotechnical bag dewatering box device with a hydraulic function. Background technique [0002] With the continuous development of social and economic levels, people have higher and higher requirements for living and surrounding environment, and the comprehensive treatment of rivers, lakes and other water bodies is becoming more and more frequent. Most of the silt cleaned out due to treatment contains certain pollutants. And because of the high moisture content, the volume is huge, often as many as hundreds of thousands or millions of cubic meters. How to carry out follow-up treatment and disposal of such a large amount of silt is a major problem in the comprehensive management of rivers and water bodies. Generally, air-drying is used for pretreatment, and then it is used for roadbed or foundation pit filling, building materials, agricultural utilization, and filling. Bu...
