The present invention can be used for following two operating condition, be respectively:
Operating condition 1: pile foundation construction perforation stage, this stage are mainly that mud mends slurry cleansing phase.Start Pulp pump 401, takes out The mud in waste pulp pond is taken, mud enters scalping 403, and through its screening, solid gravel of the diameter particle in 3mm or more falls into collection 409 in basket, rest part is returned in pulp storage tank 404.Mud in second Pulp pump suction pulp storage tank tangentially injects cyclone 406, clean mud by the outflow of 406 upper end of cyclone enter in storage tank 407, the subtle silt of partial size is from cyclone lower end drip Fall into dusting cover 408.Mud after dusting cover 408, fine slag material (diameter 0.5mm) are separated to fall into and collect in basket 409, Remaining part point returns in pulp storage tank 404.When pile foundation boring needs to mend slurry, start third Pulp pump 410, opens gate valve 301, it will be clean Slurry transportation to well bore in achieve the effect that supplement mud.
Operating condition 2: dumping mud treatment stage, this stage are mainly the processing of discarded slurry.After the completion of pile foundation boring, reinforcing bar During in cage and concrete access aperture, it is provided with waste pulp pond 200 and slurry collecting pipeline 100, mud voluntarily flows into waste pulp pond 200.Mud purifying device aspirates discarded slurry from waste pulp pond, and the larger particles in discarded slurry are after purification device 400 Into pulp storage tank.While during this processing, 500 dosing of dosing agitator tank is simultaneously diluted.Solution after dilution is logical Self priming pump 304 is crossed into reactor tank, the mud that the 4th Pulp pump 411 aspirates in pulp storage tank 404 at the same time enters reactor tank, opens The agitating function of dynamic reactor tank 700 carries out mixture the flocculating and solid-liquid separating process for completing mud is sufficiently stirred.5th slurry Solidliquid mixture after flocculation is pumped into waste pulp processing unit and carries out filters pressing by pump 309, and obtained clear water and mud cake respectively enters water storage The upside in pond 305 and conveyer 900.Clear water in tank can be pumped to dosing agitator tank ginseng through triple valve by back water pump 307 It is stirred recycling with the medicinal powder of addition, achievees the purpose that resource is made full use of to reduce discharge
Preferably, it is that the slurry-mud slurry reuse stage is mended in mud purification that this device, which can be used for the first operating condition in two kinds of operating conditions, The implementation steps in this stage are as follows:
Step 1, waste pulp pond is excavated in the position apart from pile foundation boring greater than 10m, pipe is set between waste pulp pond and pile foundation hole Road, pipe diameter are greater than 20cm, and pipeline has and ensures that mud can smoothly flow into mud pit not less than 0.5m difference in height;
Step 2,
Start Pulp pump, extract the mud in waste pulp pond, mud enters scalping, and through its screening, diameter particle is in 5mm or more Solid gravel fall into collect basket in, rest part returns in pulp storage tank.It cuts on mud edge in second Pulp pump suction pulp storage tank To injecting cyclone, clean mud by the outflow of cyclone upper end enter in storage tank, the subtle silt of partial size is from cyclone lower end Drip falls into dusting cover.Mud after dusting cover, fine slag material (diameter 0.5mm) are separated to fall into and collect in basket, remaining part Divide and returns in pulp storage tank.When pile foundation boring needs to mend slurry, start third Pulp pump, opens gate valve, extremely by clean slurry transportation Achieve the effect that supplement mud in well bore.
Preferably, it is mud conditioning stage, the implementation in this stage that this device, which can be used for second of operating condition in two kinds of operating conditions, Steps are as follows:
Step 1, waste pulp pond is excavated according to the first operating condition and connect pipeline;
Step 2, after the completion of pile foundation boring, in steel reinforcement cage and concrete access aperture during, mud voluntarily flows into waste pulp pond. Mud purifying device aspirates discarded slurry from waste pulp pond, and the larger particles in discarded slurry enter pulp storage tank after screening.
Step 3, it the dosing of dosing agitator tank and is diluted.Solution after dilution enters reactor tank by self priming pump, Mud in the pulp storage tank of 4th Pulp pump suction at the same time enters reactor tank, start the agitating function of reactor tank to mixture into The flocculating and solid-liquid separating process for completing mud is sufficiently stirred in row.
Step 4, solidliquid mixture after flocculation is pumped into waste pulp processing unit and carries out filters pressing, obtained clear water by the 5th Pulp pump Tank and conveyer are respectively enterd with mud cake.
Step 5, the clear water in tank can by back water pump through triple valve be pumped to dosing agitator tank and with the medicinal powder of addition It is stirred recycling.
Step 6, mud cake is transported outward or emergency burial by conveyer entrucking.
