Description
Technical field
The utility model relates to a kind of rubber diaphragm sealed gas cabinet, and concrete is a kind of rubber diaphragm sealed gas cabinet that adopts rolling type electromagnetism flexible anti pendulum device.
Background technique
The seal form of gas cabinet is divided into does wet two kinds; The wet gas cabinet that with water is sealing medium has been eliminated; And in dry gas holder; There is rare lubricant oil of employing to make the gas holder that sealing medium seals, has the rubber membrane of employing to make the gas holder that sealing medium seals, adopt dry lube to make the gas holder that sealing medium seals in addition.Adopt dry lube to make gas cabinet that sealing medium seals and claim to swell cabinet again, though this gas cabinet strength is high, the piston motion speed is fast, because leakage rate is big, and dry lube costs an arm and a leg and can't recycle, and do not obtain popularization.
Adopt rare lubricant oil to make the gas cabinet that sealing medium seals; Because of good seal performance is used widely; In the gas cabinet of rare seal oil, sealing means mainly contains graceful cabinet seal arrangement that adopts the metal slider formula and the novel cabinet seal arrangement that adopts rubber seal.But the piston motion speed of present rare seal oil gas cabinet is generally below 2.5m/min, and the piston motion speed improves and be difficult to, in addition, in environment water intaking at need, the use of rare seal oil gas cabinet will receive very big restriction.
Therefore, people have turned one's attention to the rubber diaphragm sealed gas cabinet that does not come into one's own for a long time again, and rubber diaphragm sealed gas cabinet has following advantage: at first be not need water in the running; Next is that the piston motion speed is fast, makes that the throughput of gas cabinet is bigger.Owing to have above-mentioned two advantages; Rubber diaphragm sealed gas cabinet is widely used in the pneumatic steelmaking of iron and steel enterprise always; Therefore rubber diaphragm sealed gas cabinet is the converter cabinet again, and is historical in the use that China is existing nearly 30 years, and orthobaric volume 80,000 m of the volume of rubber diaphragm sealed gas cabinet from introducing at that time
3, developed into now and had 20,000 m
3, 30,000 m
3, 50,000 m
3, 80,000 m
3, 100,000 m
3, 120,000 m
3With 150,000 m
3Deng the extended familys of different size, and all to be used to pressure be the pneumatic steelmaking below the 3kPa.
The maximum characteristics of the piston of rubber diaphragm sealed gas cabinet operation are that piston is in state of suspension, so motion speed can be very fast, but the piston swing that is in state of suspension has caused certain puzzlement to the utilization of rubber diaphragm sealed gas cabinet.At present, in order to prevent the piston swing, each rubber diaphragm sealed gas cabinet all is provided with levelling device, 80,000 m of a standard
3Rubber diaphragm sealed gas cabinet is provided with 6 groups of levelling devices, and the heavy top of every group of levelling device is about about 4 tons, 80,000 m of a standard
3Rubber diaphragm sealed gas cabinet also is provided with 30 root posts, and so, the vertical force that is split in like this on every root post is approximately 0.8 ton; But when tilting of the piston, the steel cable of the levelling device after the tilting of the piston has only monolateral stressed, like this; Be split in vertical force on the stressed column and be increased to and be approximately 1.6 tons, because the weight of gas cabinet piston and the pressure of coal gas are balances, this vertical force also has been balanced so; The real power that plays balanced action is the horizontal component of steel cable pulling force; And this horizontal component is very little, greatly between 12kg～120kg, when abnormal conditions appear in piston; Because this power is too little, the stuck piston of rubber diaphragm sealed gas cabinet often appears.
Current because the needs of producing; The gas cabinet of the rubber diaphragm sealed piston of one-part form has appearred adopting; Its working pressure of bearing has been 3～4 times of traditional rubber diaphragm sealed gas cabinet, even higher, and also heavy 3～4 times than the rubber diaphragm sealed gas cabinet of tradition of piston weight; If also the levelling device by the rubber diaphragm sealed gas cabinet of tradition prevents tilting of the piston, just be easy to cause the tilting of the piston swing uncontrollable.
The patent No. is that the Chinese patent of ZL200620148390.8 discloses a kind of rubber diaphragm sealed piston type gas cabinet, comprises column, cabinet base plate, piston base plate, lower support frame, piston holder, upper bracket, rubber curtain, side plate and top board, and said side plate is a cylindrical shape; The equidistant outside of being fixed in said side plate of said column; Said lower support frame is fixed in said side plate lower inside, and said upper bracket can slide up and down along said side plate inboard, seals with said rubber curtain between said upper bracket and the said side plate; Said piston base plate is fixed in said piston holder bottom; Said piston holder can slide up and down along said upper bracket inboard, and the top of said top board is provided with ventilation plant, outside said side plate, is provided with automatic bleeding device; Also comprise the piston levelling device; Said piston levelling device comprises counterweight pulley, piston pulley, counterweight and wire rope, is fixed with said counterweight pulley on said top board top along periphery, is fixed with said piston pulley along inside circumference is equidistant; Said counterweight is connected with said wire rope one end, is suspended to outside the said side plate through said counterweight pulley; Said piston holder is connected with the said wire rope the other end, is suspended in the said side plate through said piston pulley.Though the piston levelling device of this rubber diaphragm sealed gas cabinet can return to level after can making tilting of the piston swing to a certain extent; The defective that causes piston to block easily but the horizontal component of steel wire of still failing to have solved balanced action is little can't be applicable to the bigger piston of weight in the rubber diaphragm sealed gas cabinet of one-part form; In addition, when piston occurred suddenly stopping waiting special state, the steel cable of levelling device was also broken easily.
Therefore, need the levelling device of existing rubber diaphragm sealed gas cabinet be improved,, increased the horizontal component of balanced action, make that piston is difficult for blocking, and can be applicable to the anti-pendulum of piston of the rubber diaphragm sealed gas cabinet of one-part form through improving its structure.
