Description
Technical field
The present invention relates generally to storage arrangement field, particularly a kind of powder tank, and comprises the mixing plant of this powder tank, is particularly useful for helical coil plank frame.
Background technology
Powder tank is the vitals of concrete mixing plant, for as powder class material as the storage container of cement, fly ash etc.What the powder tank of prior art adopted usually is stack shell that is assembled or welding, and the board-like powder tank of helical coil is widely used in, in grain, the storage of cement and sewage treatment system, concrete mixing plant being applied less.
The board-like powder tank of helical coil adopts spiral steel silo structure, its steel silo is due to special manufacture craft, rise storehouse speed fast, but the bulkhead of silo to be engaged with steel plate by steel plate and to form, form is similar to the flexible pipe of folder spring steel, its ability of vertically bearing air pressure is poor, is thus rarely used in and stores the powder such as cement, fly ash class material in mixing plant.
In the process of mixing plant work, when powder class of annotating in powder tank is as materials such as cement, because powder class material generally adopts gas to carry, cause malleation in tank, when material in tank is close to when filling it up with, because in tank, Spatial Residual is little, tank internal pressure sharply increases, and easily causes and lifts useful event.
In order to avoid the vertical tensile failure of silo, increase silo bear the ability that wind carries, usually weld if the stud such as channel-section steel, angle steel is to strengthen the rigidity of bulkhead at silo inwall vertical (from top to bottom) in prior art, but welding inevitably causes damage to thin-walled silo, easily there is the weld defect burning bulkhead, also can destroy steel plate zinc coating in addition, cause easily getting rusty, be difficult to antirust and rust cleaning, affect attractive in appearance.
In addition, the stud overall length of aforementioned silo inwall is generally more than ten meter, considers that actual the making of every root stud reaches 2-3 rice from construction convenience, welding operation with rise storehouse and need hocket, namely, after first rising storehouse to certain altitude, stop rising storehouse, carry out the welding of top stud, after top stud welds, then rise storehouse again to certain altitude, stop rising storehouse, carry out the welding of intermediate studs, the rest may be inferred, until rise storehouse to design height.
Aforementionedly rise storehouse and welding is discontinuous operation, the inevitably stability of impact volume storehouse occlusion muscle quality; In addition, the jig of about 2 meters must be taken during welding stud in cylinder, waste time and energy, and belong to aloft work, there is potential safety hazard; And welding on thin-walled silo, welding speed is slow, has a strong impact on the installation rate of mixing plant.
Summary of the invention
In view of this, the present invention proposes a kind of powder tank, this powder tank avoids at silo inwall welding stud, avoid the problem that welding causes easily getting rusty, both ensure that the rigidity of steel silo, and turn improved the manufacturing speed of powder tank, reduce the labour intensity of workman, and good looking appearance.
