Problems solved by technology
This treatment method has the following disadvantages: first, it needs a larger site or slurry pool to store waste pulp; second, the amount of slurry transported abroad is large, and it is not convenient to use large special tankers on busy urban roads; third, The slurry contains part of cement and stratum soil, which is prone to sedimentation and solidification during transportation, and it is not easy to clean up in a special tanker; fourth, special vehicles are required, and the cost is high; fifth, the waste cement slurry contains a lot of water and is also discarded at the same time , in actual construction, a large amount of water is needed to make pulp, which creates a contradiction that on the one hand, a large amount of pulp is discarded, and on the other hand, a large amount of water must be replenished to make pulp

Embodiment
[0049] The waste slurry is stored in the sewage pool 1, and the dredging pump 7 in the pipe valve system 16 is controlled by PLC to transport the waste slurry to the pre-screening device 8, and the vibration motor of the pre-screening device 8 is turned on. Particles larger than 1 mm are screened out and fall into the slag material conveying device 6 to obtain the primary treated slag material 2, which is sent to the stockyard, and the sieved mud enters the primary slurry pool 10, which is equipped with double-layer blades Stirrer, which is convenient for full stirring, and the PLC controls the stirrer 9 to start working. At this time, a certain amount of chemical agents can be added as needed, such as acid or alkali for adjusting the acid-base balance of the mud or flocculation to improve the filtration performance of the mud in Chinese agent or filter aid. After fully stirring evenly, set aside.
[0050] The filter press 4 is opened, the filter plate of the filter press 4 i...

The invention discloses a waste jet grouting cement paste fast dewatering method and device thereof, relating to waste cement paste treatment. The steps of sieving pretreatment, adding chemical agent, stirring and extrusion dewatering are adopted, water and slag in the waste cement paste can be separated by a special device, the slag after separation is only 25% of the original waste cement pastein volume, and meanwhile the slag after blow drying can be transported by a common vehicle while clear water which is 60-75% of the original waste cement paste in volume can be obtained for pulping again. The invention can save raw materials, protect environment and reduce construction cost.
Description
technical field [0001] The invention relates to the treatment of waste cement slurry, in particular to a rapid dehydration method and equipment for rotary spraying waste cement slurry. Background technique [0002] With the development of urban construction, the rotary grouting construction method has been widely used in the construction of foundation reinforcement, foundation water stop, and underground diaphragm wall. However, rotary grouting construction will produce a large amount of waste cement slurry. The current treatment method for waste slurry is to store it in a mud box or a mud pool on site, and transport it outside with a special tanker after reaching a certain reserve. This treatment method has the following disadvantages: first, it needs a larger site or slurry pool to store waste pulp; second, the amount of slurry transported abroad is large, and it is not convenient to use large special tankers on busy urban roads; third, The slurry contains part of cement...
