Description
Technical field
The present invention relates to a kind of gas cabinet parts, particularly a kind of piston of gas cabinet.
Background technique
Gas cabinet is a Steel Vessel of storing industry and domestic gas, and two kinds of wet gas cabinet and dry gas holders are arranged.Wet gas cabinet is the cover skeleton symbol cylindrical structural with water-stop; Dry gas holder is with thin oil or rubber diaphragm sealed piston cylinder operator.
Adopt rubber diaphragm sealed gas cabinet; Be called the Wei Jinsi cabinet again, it is to seal with the film formed leather bag of rubber, and rubber pattern plasticity is big; Its piston motion speed can reach more than the 5m/min, and this is that other gas cabinets except that the swelled moulded coal gas holder of drier oil sealing are beyond one's reach.Also have, the temperature that rubber membrane bears is higher than thin oil, and is not afraid of dust, has more advantage compared to the gas cabinet of other types.But as the special-purpose gas cabinet of the RECOVERY OF CONVERTER GAS of making steel, it is used for the splendid attire blast furnace gas is just to begin to grow up in recent years to this gas cabinet always.
With Wei Jinsi cabinet splendid attire blast furnace gas, press the classification of caulking gum hop count, multi-section type gas cabinet and one-part form gas cabinet are arranged.There is pressure surge when portable in piston becoming the section place in the multi-section type gas cabinet, the working stability and the reliability of gas cabinet had considerable influence, and the one-part form gas cabinet has been eliminated this defective, thereby has more been favored.
One-part form rubber membrane gas cabinet is the key factor that must consider to piston stroke; Under the certain prerequisite of volume, if diameter is too little, piston stroke is just too big; If diameter is too big; The intensity and the rigidity on the piston of gas cabinet and gas cabinet cabinet top just greatly reduce, and therefore, a rational blade diameter length ratio must be arranged.We are with one 80,000 m
3～10 ten thousand m
3One-part form be example; If the diameter of gas cabinet confirms according to traditional diameter 58m, like this, rubber membrane in the length of gas cabinet cylindrical shell short transverse generally at 15m～16m; Depth pistion can reach about 17～18m; Because the side and the bottom surface of piston receive even positive pressure, piston side working pressure can reach 10kPa above (every square metre of pressure that reaches more than 1 ton), and so high working pressure acts on the so high piston side wall; Cause piston side surrender unstability easily, job security is low with stability.Can't solve between piston rigidity problem, mostly one-part form rubber membrane gas cabinet of the prior art is little volume gas cabinet; Yet little volume gas cabinet can not adapt to the needs of modern production.
Therefore how to strengthen piston rigidity and intensity, with raising pistons work Security and stability, and the volume of increase one-part form gas cabinet, be worth research.
Summary of the invention
In view of this; The purpose of this invention is to provide a kind of gas cabinet pillow formula piston, it can solve the rigidity problem of the high sidewall piston of major diameter, guarantees the Security and the stability of pistons work; The design volume of lifting one-part form gas cabinet that can be very big satisfies the needs of modern production.
Gas cabinet pillow formula piston of the present invention; Comprise spherical shape piston plate, be arranged on the piston plate and with piston plate fit shape following sub-truss, the column that is set up in parallel along the piston plate edge, is connected the sub-truss of adjacent upright posts and is arranged at the piston side wallboard on the column, also comprise the last sub-truss that is arranged at the column upper end and be connected sub-truss and the intermediate support truss of following sub-truss.
Further, the said sub-truss of going up comprises the last collar tie beam and the bolster that is connected collar tie beam and column that is positioned at top, piston plate middle part;
Further, said bolster is the arc beam of arc top towards piston plate, and perhaps said bolster is lower than the oblique straight beam that connects column one end for connecting an end of going up collar tie beam;
Further, said following sub-truss is provided with the lower ring beam corresponding with last collar tie beam, and said intermediate support truss comprises first intermediate truss that connects last collar tie beam and lower ring beam;
Further, said first intermediate truss is arc strut I or allotment strut I;
Further, said intermediate support truss also comprises between first intermediate truss and column, connects second intermediate truss of bolster and following sub-truss;
Further, said second intermediate truss is an arc strut II;
Further, said second intermediate truss comprises the allotment strut II that connects bolster and following sub-truss, the inclined support bar I and the inclined support bar II that is connected allotment strut II and last collar tie beam that is connected column and allotment strut II;
Further, also comprise the box beam that is looped around the piston plate outer rim, the lower end of said column, piston plate outer rim and following sub-truss all are fixed on the box beam.
Beneficial effect of the present invention: gas cabinet pillow formula piston of the present invention except piston plate is provided with down sub-truss, also is provided with sub-truss in the column upper end; And between last sub-truss and following sub-truss, also be provided with the intermediate support truss; Thereby strengthened the rigidity and the intensity of piston greatly, piston side stress-bearing capability is stronger, can increase the design size of piston diameter and height; Improve the volume of gas cabinet, satisfy the needs of modern production.
