Abstract
Vacuum preloading roly-poly type captation, including the tank body being embedded under mud top layer, it is arranged at least one immersible pump of tank base, the liquid level controller being arranged in tank body and automatically controls electronic box, described tank body is up-small and down-big roly-poly type cylinder, tank body upper end is exposed mud top layer and is provided with pipeline connection vacuum pump, at least one inlet is offered on barrel in the middle part of tank body, immersible pump connects outlet pipe, outlet pipe stretches out tank body, and described liquid level controller is set at least one hydrargyrum floating-ball level switch.It is effectively increased service life and the accuracy of detection of liquid level controller, and by tank design is become roly-poly shape, tank body material is that matter polypropylene weight is the most corrosion-resistant, it is easy on mud mud displacement install, improve it to process and the stability of Treatment of Sludge water collecting equipment at blowing-filling sludge, improving drainage efficiency, service life of equipment is long, is hardly damaged.
Description
Technical field
The present invention relates to a kind of moisture separation device, a kind of soft base vacuum preloading processes drainage by suction system.
Background technology
It is one of current treatment of soft foundation industry the best way that soft base vacuum preloading processes, and its time is short, ground degree of compaction high and good stability.Current soft base vacuum preloading processes conventional jetting stream vacuum equipment and processes, and vacuum when monomer construction area is more than 20,000 square metres, can need substantial amounts of jetting stream vacuum equipment to construct with meeting construction needs.The inefficient shortcoming of jet vacuum pump becomes quite to highlight.
China Patent Publication No. is that CN 203808042 U discloses a kind of soft base vacuum preloading process negative-pressure drainage device, it is characterized in that: include steam-water separation tank, the vacuum suction pipe being connected with vacuum pump it is provided with, equipped with electromagnetic valve on vacuum suction pipe at the top of steam-water separation tank；The sidewall of steam-water separation tank connects and has the water-permeable pipe imbedded in soft base, equipped with stop valve and filter on water-permeable pipe；Bottom in steam-water separation tank is provided with support orifice plate, supports and is set between orifice plate and the bottom of steam-water separation tank inhale sand chamber, inhales sand intracavity and is provided with suction cutter, and steam-water separation tank is externally provided with jet vacuum pump, and jet vacuum pump is connected with suction cutter by sand suction pipe；Being provided with discharge outlet equipped with two draining pumps in parallel, the upper portion side wall of steam-water separation tank supporting on orifice plate, discharge outlet is connected with draining pump by pipeline.Its technical scheme solves the problem that prior art efficiency is low, energy consumption is high, but its Liquid level refer to fluid level scale line the most in the description, obviously by impossible during observation Liquid level line traffic control water level, but its technical scheme also not specifically discloses its mode, is further improved.
Furthermore the tank body changing technical scheme is common cartridge type housing, the most difficult by dress in the displacement of mud Sludge Surface, imbed mud top layer, vacuum easily produces when opening and rocks and cause service life shorter, haves much room for improvement.
Additionally the tank body of general prior art mostly is metal shell, although its old of making is relatively low, but its heavier-weight and its decay resistance are poor, ultra-soft foundation installation displacement is the most difficult, and the most corrosion-resistant, fragile, not adapting to the environment that soft base vacuum preloading processes, service life is shorter, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of service life length, effectively control water discharge time, improve the vacuum preloading roly-poly type captation of drainage efficiency.
For realizing the object of the invention, provide techniques below scheme: vacuum preloading roly-poly type captation, including the tank body being embedded under mud top layer, it is arranged at least one immersible pump of tank interior, electronic box is automatically controlled outside the liquid level controller being arranged in tank body and tank body, it is characterized in that the spherical cylinder of roly-poly type that described tank body is up-small and down-big, tank body upper end is exposed mud top layer and is provided with pipeline connection vacuum pump, at least one inlet is offered on barrel in the middle part of tank body, immersible pump connects outlet pipe, outlet pipe stretches out tank body, described liquid level controller is set at least one hydrargyrum floating-ball level switch.
As preferably, described tank body material is polypropylene, lightweight corrosion-resistant.
As preferably, described tank body includes the cartridge type first half and the diameter spheroidal lower half more than cartridge type first half diameter.Lower half is that spheroidal utilizes buoyancy to be easy in the displacement installation of mud Sludge Surface, compressive resistance is high, the water making vacuum pump suck by this kind of setting resides in rounded bottom part because of weight effect, the center of gravity of whole tank body is declined, lower half is that semicircle is spherical utilizes buoyancy to be easy in the displacement of mud Sludge Surface by dress, lower half is that spheroidal compressive resistance is high, good stability.
As preferably, hydrargyrum floating-ball level switch is provided with two one on the other, by cable with tank body outside the electronic box that automatically controls be connected.
Beneficial effects of the present invention: the present invention is when soft base monomer construction area is more than 20,000 square metres, formed big face tank body inlet by multiple sumps and connect multiple discharge pipe lines, composition vacuum drainage network, vacuum tube in each collector pipe precompressed true with booster-type (patent No. ZL200810156787.5) is connected, evacuation area 5000-10000 square.The water liquid that tank body collects in forced-ventilated vacuum pipe network under negative pressure state.Formed big face vacuum by multiple sumps to catchment, one 55 kilowatts of vacuum pump connects 3-10 sump, sump has multiple inlet, vacuum tube in one inlet precompressed true with booster-type (patent No. ZL200810156787.5) is connected evacuation area 800-1000 square, compared with prior art jetting stream vacuum equipment construction, every 800-100 square needs electricity consumption 7.5 kilowatts, and unit are energy consumption saves 60%-90%.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
