Abstract
The invention discloses a device for reducing water ratio of sludge. The device for reducing the water ratio of the sludge comprises a hollow transmission shaft, wherein a water drain pipe is arranged inside the improved transmission shaft; an upper spiral blade and a lower spiral blade are arranged on the transmission shaft; an electrically-conductive plate is arranged below the upper spiral blade; the electrically-conductive plate is insulated from the upper spiral blade; a metal water filtering layer is arranged on the upper surface of the lower spiral blade; the metal water filtering layer is insulated from the lower spiral blade; a power cord is arranged inside the transmission shaft; the positive electrode of a power supply is connected to the electrically-conductive plate; and the negative electrode of the power supply is connected to the metal water filtering layer. Compared with the prior art, under the action of an electromotive force, water migrates towards the lower blade, while a vacuumizing position is rightly above the lower blade, so that the vacuumizing efficiency is improved; and along with the downward movement of the upper blade, the upper blade is always separated from dry sludge to be in contact with the sludge with relatively high water ratio, so that the water and heavy metal migrating capability of the electromotive force is improved.
Description
Technical field
The present invention relates to environment, civil engineering, hydrotechnics field, especially a kind of recycling treatment for contaminated mud.
Background technology
High-moisture and be rich in the mud of heavy metal if do not process, is arbitrarily stacked and is easily formed secondary pollution, and occupied ground.Want to make its resource utilization must water cut and to reduce heavy metal ion free.Vacuumizing is one of method of water cut, but it can only effectively reduce near the moisture of the regional area of evacuated panel, and apart from evacuated panel zone far away, moisture lowers efficiency lower.Electrokinetics can make moisture and heavy metal to negative electrode (negative pole) enrichment, anode (positive pole) near zone can form the low-down dry ground district of water ratio, but, formation (resistance increase along with the dry ground district, electric current reduces), its migration moisture and heavy metal ability can descend rapidly, in addition, because the enrichment of moisture, the water ratio of the soil body at negative electrode place can increase.Also someone proposes to vacuumize with electrokinetics and unites the low soil moisture content of use, but their evacuated panel position and electrode position are all fixed, vacuumize and the certain hour of switching on after, its inefficiency problem can't solve, and mud different zones moisture reduces the degree varies sample.In addition, heavy metal pollution problem can't be eliminated or reduce to this integrated processes.With the heavy metal of cement in can solidification sludge, make it no longer separate out and form pollution, but the method cement consumption to reach the 30-40% of sludge volume, in addition more, very uneconomical.
In a word, also do not have now a cover not only effectively but also economical, can reduce simultaneously moisture percentage in sewage sludge and prevent method and the support equipment of heavy metal secondary pollution.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and a kind of device that reduces moisture percentage in sewage sludge is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of device for reducing moisture percentage in sewage sludge, the transmission shaft that comprises a hollow, this changes and is provided with water shoot in the transmission shaft, it is characterized in that: also be provided with screw blade and lower screw blade on the described transmission shaft, on described, be provided with conducting plates below the screw blade, this conducting plates and the insulation of upper screw blade, be provided with metal drainage layer at described lower screw blade upper surface, this metal drainage layer and described lower screw blade insulation, lower end at metal drainage layer is provided with water port, this water port is connected with described water shoot, in described transmission shaft, also be provided with supply lead, the positive pole of power supply is connected on the described conducting plates, and the negative pole of power supply is connected on the described metal drainage layer.
Described metal drainage layer is the reinforcing bar double-edged fine-toothed comb, is provided with filter cloth in the lower end of reinforcing bar double-edged fine-toothed comb, and described water port is arranged on the filter cloth lower end.
Lower surface at described lower screw blade is provided with the grout nozzle, and the grout pipe that is connected with this nozzle is arranged in the transmission shaft.
Described upper screw blade is fixed on the blade set collar, but being arranged on the transmission shaft at this blade set collar axial slip.
Be provided with draw-in groove at described blade set collar, be provided with Ka Tai at described transmission shaft, described draw-in groove is arranged on Ka Tainei.
Compared with prior art, the invention has the beneficial effects as follows:
1, under electrodynamicaction, moisture moves to lower blade, and the position that vacuumizes is exactly on lower blade, thus the efficient that is conducive to vacuumize.
2, along with, cutter is constantly descending, it always breaks away from dried mud and contacts with the larger mud of water ratio, thereby has improved the ability of electric power migration moisture and heavy metal.
3, when heavy metal is enriched in the mud bottom, as long as stir the effect that just can play heavy metals immobilization with the mud of cement and bottom, does not need to mix with all mud, thereby saved cement consumption in a large number.
4, this equipment can be by separately as the instrument that removes to reduce the mud water ratio, and same, it also can be used alone as curing heavy metal (in the mud bottom); Also can on the basis of curing heavy metal, continue to make cement mixing pile.Thereby an equipment has multiple use.

Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated, as shown in Figure 1, a kind of for reducing the water ratio device, it is by upper screw blade 1, and the supporting part such as lower screw blade 2, hollow rotation axis 3 and water shoot 4 forms, described its profile of upper lower blade is similar to water screw, lower screw blade upside is opened shallow slot, and rubber pad 21, filter cloth 22 and concrete reinforcement bar double-edged fine-toothed comb 23 are installed above the shallow slot from bottom to top successively, sees Fig. 4.Such as Fig. 2, shown in Figure 3, be provided with shallow slot at the lower blade downside, cement throwing jet mouth 24 is arranged in the lower surface shallow slot.The downside of upper screw blade is opened shallow slot, and rubber pad and conducting plates 11 are installed above the shallow slot, sees Fig. 5.Described transmission shaft 3 is hollow steel tube, in establish water shoot 4, grout pipe 5 and two wires 6, wherein water shoot 4, grout pipe 5 are connected with water port and grout nozzle on the lower screw blade 2, one in two electric wires are connected with the reinforcing bar grate 23 of lower screw blade, one is connected with the conducting plates 11 of upper screw blade, what wherein be connected with conducting plates 11 is positive source, and what be connected with the reinforcing bar double-edged fine-toothed comb is power cathode.In addition, it is to connect by draw-in groove 7 that upper screw blade 1 is connected with transmission shaft 3, and upper screw blade can be along axially the moving up and down of transmission shaft 3, referring to Fig. 6 within the specific limits.
Because energising, concrete reinforcement bar double-edged fine-toothed comb 23 and conducting plates 11 be easily corrosion all, so the present invention is designed to them removable parts, so that change after corrosion.Simultaneously, because upper lower blade belongs to expensive components, so in order to prevent corrosion, they all form the insulation relation with reinforcing bar double-edged fine-toothed comb and conducting plates.
