The POC moulded coal gas holders, it is characterised in that:The balance mechanism is set to coal gas cabinet top, and balance mechanism includes that leveling is matched
Weight, the leveling counterweight are located on the outside of cabinet wall, and it is straight that two steel wire ropes in leveling counterweight act on piston by sheave respectively
2 points on diameter direction;
The POC moulded coal gas holders, it is characterised in that:The releasing device includes top opening and diffuses valve body, top opening
Including sheave, mandril and steel wire rope;When the piston of gas chamber rises to a gas chamber high position, the barrier support top of piston is pushed up
The mandril for being installed on cabinet top is opened, mandril top sheave drives steel wire rope to ramp up, pulling force is passed to diffusion valve by guide wheel
The valve deck of body so that valve deck is detached from valve body, carries out coal gas in cabinet and diffuses.
The beneficial effects of the invention are as follows:So that gas holder is met use condition, and save enterprise investment,(Relative to tearing open
It removes, rebuild gas chamber needs at least 1 year, transformation only needs 3 months), coal gas diffusion is reduced, production cost is reduced,
It reduces environmental pollution, there is certain economic benefit and social effect.Use the maximum allowable fortune of the improved gas chamber of this method
Scanning frequency degree is 2 times of Primordial Qi cabinet, and handling capacity also reaches 2 times of Primordial Qi cabinet, and balance ductwork pressure effect becomes apparent from.
There is presently no relevant patent, the inventions of the technology can solve to scrap for the improvement and design technology of POC moulded coal gas holders
The Utilizing question again of POC moulded coal gas holders saves fund for enterprise, and the transformation time is short, reduces coal gas diffusion, has significant
Economic benefit can also play the role of environmental protection.

Specific implementation mode
As shown in figs. 1-7:A kind of POC moulded coals gas holder is made of bottom of cabinet plate, piston, gas holder cylinder and cabinet top, further includes
There are sealing mechanism, piston guide mechanism, balance mechanism, releasing device and oil supply mechanism in mating auxiliary body;
The sealing mechanism includes gas chamber siding 1, and 2 on sealing angle steel installation gas holder siding, the sealing angle steel other side passes through spiral shell
It tethers and connects first guide part 3, rubber pattern 4 is equipped between the sealing angle steel and the first guide part, bottom of gas holder is equipped with
Piston box beam 5, piston-type box beam outside are equipped with a holder 6, which is equipped with sealing channel steel 7, and sealing channel steel top passes through
It is bolted second guide part 8, the rubber membrane lower end is set between sealing channel steel and the second guide part;The piston-type
Box beam top is equipped with barrier support 9, and corrugated sheet 10 is hung on the outside of barrier support, and corrugated sheet lower end is located on the outside of the second guide part;
The barrier support upper inner and piston box beam lower inside are respectively equipped with position-limited wheel 11;By contact oil pressure sealing mechanism
It transform rubber membrane flexible connection sealing as, deformation requirements of the sealing mechanism to cabinet can be effectively reduced in this way, remove former cabinet
Piston wheel bracket, design meet barrier support of the rubber membrane after by gas pressure.
The balance mechanism is set to coal gas cabinet top, and balance mechanism includes leveling counterweight 12, and the leveling counterweight is located at cabinet wall
Outside, two steel wire ropes in leveling counterweight act at 2 points on piston diameter direction by sheave 13 respectively;It removes former
Piston holder and attached stable steering mechanism are oriented on barrier support top and box ring beam lower part setting piston anticollision rubber
Wheel is arranged levelling mechanism in cabinet top, acts on piston diameter direction at 2 points by two steel wire ropes outside cabinet in leveling counterweight,
Inhibit the inclination in piston diameter direction, the quantity of leveling counterweight holds size setting according to cabinet, symmetrical in cabinet excircle.Balance
Mechanism principle:Two steel wire ropes act on 2 points on piston diameter direction in leveling counterweight, it is assumed that piston A points tilt upwards, A
Side steel wire rope will fluff, and a side pistons are reduced by counterweight pulling force, and the sides b steel wire rope will bear more counterweight pulling force, to the sides B
Piston will bear more upward pulling force, reach piston balance, vice versa.
The releasing device includes top opening and diffuses valve body, and top opening includes sheave 15, mandril 16 and steel wire
Rope 17;When the piston of gas chamber rises to a gas chamber high position 18, the open-top top for being installed on cabinet top in barrier support top of piston
Bar, mandril top sheave drive steel wire rope to ramp up, pulling force are passed to by guide wheel the valve deck 19 for diffusing valve body so that valve
Lid is detached from valve body, and coal gas carries out coal gas in cabinet from desorption tube 20 and diffuses upwards.Former releasing device is that piston seal rubber strip is super
It crosses after side plate diffuses hole and is diffused, improved sealing mechanism sealing principle is different, it is therefore desirable to it is open-top to design a set of machinery
Bleeding device meets the functional requirement of gas chamber emergency diffusion.
Valve body and mechanical top opening mechanism, when piston is close to cabinet top, piston top are diffused top of gas cabinet setting is a set of
The open-top cabinet top releasing device steel wire rope mandril in portion diffuses valve body to be promoted, discharges coal gas in cabinet.
The present invention can utilize the gas chamber scrapped again, reduce investment, and transformation speed is fast;Non-contacting seal mechanism shape
Formula can effectively adapt to the deformation of original gas chamber, be conducive to improve the piston speed of service;Balance mechanism form can guarantee that gas holder is lived
The even running of plug;Releasing device form can effectively prevent the destruction that piston is rushed to summit to cabinet body structure, it is ensured that safety.
