Secondly, it relies on the rubber membrane sealed, need not liquid, does not need water even more, is real dry-type gas holder, is particularly useful for the northern area. Thirdly, the dust content of the gas tank is not as strict as that of a thin oil tank. Fourthly, the gas tank bears higher working conditions than a thin oil tank; under the same condition, the gas holder can save a part of energy, and is beneficial to environmental protection and energy conservation.
The reason why the rubber membrane seals the gas holder is that the handling capacity is strong is that: a clearance of more than 400mm is left between the piston of the gas chamber and the outer cylinder of the gas chamber (the diameter of the piston is about half meter smaller than that of the cylinder of the gas chamber), and the piston is not limited like a thin oil sealed gas chamber, so that the piston can obtain stronger throughput capacity at higher running speed. Such a piston is large in its amount of sloshing during operation. With the development of the rubber membrane sealed gas chamber, the rubber membrane sealed gas chamber is changed from a converter gas medium with low storage pressure to a blast furnace gas medium with high storage pressure, the bearing pressure of the rubber membrane sealed gas chamber is increased by many times, and the weight of a piston is increased by many times. If the piston is light, the impact of the piston swing on the outer cylinder of the gas chamber is light, and if the piston is heavy, the impact of the piston swing on the outer cylinder of the gas chamber is heavy.

Referring to fig. 1, a counter-damping weight includes a weight ring 1 and a tension spring 2, a rolling mechanism 3 is disposed below the weight ring 1 to roll the weight ring 1 on an installation base through the rolling mechanism 3, and the tension spring 2 is correspondingly disposed on an outer circumferential surface of the weight ring 1. The extension springs are provided with a plurality of extension springs which are evenly distributed on the peripheral surface of the counterweight ring 1. The reverse damping balance weight utilizes the mechanical principle of a wobble plate, namely, the unstable piston is converted into a stable state by utilizing artificially manufactured vibration (the swinging frequency and the swinging amplitude of a balance weight ring are calculated in advance). The balance weight ring with the tension spring 2 is used as a reverse swing source, and the damping balance weight swings reversely to prevent the gas holder piston from shaking.
In the scheme, the rolling mechanism 3 is a universal wheel or a ball arranged at the bottom of the counterweight ring 1; of course, the balls can also be correspondingly arranged on the mounting base. The other end of the tension spring 2 is provided with a mounting plate 4 so as to facilitate the installation between the tension spring 2 and the gas chamber piston.
A single-segment piston is taken as an example for comparison: fig. 2 is a schematic structural view of a conventional single-stage rubber mold sealed gas holder, and fig. 3 is a schematic structural view of a single-stage rubber mold sealed gas holder with a reverse damping weight. As can be seen from the comparison between fig. 2 and fig. 3, the counter damping stable gas holder piston is improved based on the conventional single-stage gas holder piston.
Specifically, the basic components of the gas holder piston are a piston arch 5, a piston ring beam 6 and a T-shaped baffle bracket 7, wherein the piston ring beam 6 is used as an installation foundation. The reverse damping counter weight that adds sets up in the top of piston ring roof beam 6 through rolling mechanism 3 on the one hand to make counter weight ring 1 can roll on piston ring roof beam 6, and on the other hand, extension spring 2 is installed on T baffle support 7, can restrict the swing range and the frequency of swing of counter weight ring 1 again with the help of the extension spring.
For convenient installation and guarantee of installation reliability, the tension spring is arranged on the T-shaped baffle plate bracket 7 through the installation plate 4 at the end head of the tension spring.
In the single-section type gas chamber piston, the counter weight ring 1 in the reverse damping counter weight can be acted as by the movable counter weight 8 in the traditional single-section type gas chamber piston, namely the movable counter weight 8 in the traditional single-section type gas chamber piston still keeps the function of adjusting the gas chamber piston level, but because of the arrangement of the rolling mechanism 3 and the tension spring 2, the matching form of the counter weight ring 1 and the piston ring beam 6 below is changed.
The principle of action is (see fig. 3):
the center of gravity of the piston is approximately near the center of the ring beam 6 (point B), and the fulcrum of the piston oscillation is at the center line of symmetry of the piston arch 5 (point a). The piston swings, namely the acting point of the weight W of the piston is at the point B, and the swinging radius of the piston is from the point A to the point B, which is the pendulum effect. The counterweight ring 1 is not fixedly connected with the piston, but is connected with the T baffle bracket 7 (a part of the piston) through a tension spring on the peripheral surface of the counterweight ring 1, and the counterweight ring 1 and the gravity direction of the piston are transmitted through a rolling mechanism 3 (a universal wheel, a ball and the like). The piston oscillates very rapidly, since it acts directly on the gas G. When the piston (wherein take piston ring roof beam 6 as the representative) swings, the relation that the counterweight ring 1 is not directly rigidly connected with the piston, only flexibly connected between them makes the counterweight ring 1 not swing synchronously with the piston, which forms the reverse swing, forms the reverse swing damping, thus greatly reduces the swing amplitude of the piston, achieves the effect of stabilizing the piston swing. The counter-damping balance weight is added on the basis of the pendulum effect, so that the effect of preventing the gas holder piston from swinging can be achieved, namely, the balance weight ring 1 is always in a swinging state, and the piston (represented by a piston ring beam 6) is relatively static.
Taking a certain two-section piston as an example for comparison, the following description is given: fig. 5 is a schematic structural view of a conventional two-section type rubber mold sealed gas holder, and fig. 6 is a schematic structural view of a two-section type rubber mold sealed gas holder with a reverse damping weight. As can be seen from the comparison between fig. 5 and fig. 6, the counter damping stable gas holder piston is improved based on the conventional two-segment gas holder piston.
Specifically, the reverse damping stable gas holder piston comprises a piston arch 5, a piston ring beam 6, a T-shaped baffle bracket 7 and a piston frame 9 (the two-section gas holder piston is inherently composed), wherein the piston ring beam 6 is used as an installation foundation. The piston ring counterweight device further comprises a reverse damping counterweight, a counterweight ring 1 in the reverse damping counterweight is arranged above the piston ring beam 6 through a rolling mechanism 3, and the counterweight ring 1 is arranged on the piston frame 9 through a tension spring 2. Both the single-segment gas holder piston shown in fig. 3 and the two-segment gas holder piston shown in fig. 6, there are multiple sets of tension springs 2 mounted on the counterweight ring 1, as shown in fig. 8. Each group of tension springs 2 is arranged on the piston frame through a mounting plate 4 at the end head of the tension spring.
The reverse damping arrangement acts to slow the piston from rocking, regardless of the piston oscillations caused by the factors. The gas chamber additionally provided with the reverse damping counterweight can eliminate a traditional leveling system for leveling a steel wire rope heavy hammer.
The following specific engineering examples are used for illustration:
(gas holder) outer cylinder 10 diameter 61.8 meters, working pressure 8kPa, total piston weight 2400 tons. Wherein, the steel structure is 670 tons, the fixed counterweight (namely the piston ring beam 6) is 1576 tons, and the leveling counterweight is 110 tons (the leveling counterweight without the steel wire rope is 24 tons). The leveling weight of 110 tons and the leveling weight of the steel wire rope are 24 tons and 134 tons in total. Accounting for 5.6 percent of the total weight of the piston.
The leveling balance weight in the traditional rubber membrane sealed gas chamber is used for adjusting the levelness of the piston, the state is fixed after the adjustment is finished, and the action of the leveling balance weight is finished. When the piston swings, all objects on the piston form a whole, so that the stability effect is poor, and great potential safety hazards exist.
The damping counter weight is adopted as a reverse swing source, the gas chamber piston is prevented from shaking through the reverse swing of the damping counter weight, a traditional leveling steel wire rope counter weight leveling system can be omitted, the total weight of the piston is reduced, and the running speed of the piston is increased. The reverse damping counterweight also has a certain anti-seismic effect, and the device also has the effect of protecting the piston during an earthquake (particularly, playing a role of mainly destroying transverse waves).
The reverse damping counterweight has the advantages of wide material sources of all components, easy processing and manufacturing and low manufacturing cost; the device can be suitable for a single-section type rubber mold sealing gas chamber, a two-section type rubber mold sealing gas chamber and similar gas chambers; the existing equipment can be directly improved.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
