Abstract
An automatic dust cleaning device of a butterfly valve is characterized in that a dust collecting box is mounted on the lower portion of a butterfly valve body, a screw conveyor is mounted in the dust collecting box and driven by a motor and a speed reducer, a dust cleaning outlet is arranged on the lower portion of the dust collecting box, and an air locking discharge valve is mounted below the dust cleaning outlet. The screw conveyor in the dust collecting box is driven to rotate by the small-power motor, and accumulated dust in the valve is scraped and thrown off by an impeller of the screw conveyor and rotates to the lower portion of the dust collecting box and then can be cleaned periodically, so that dust can be cleaned automatically, and valve blocking can be avoided. In addition, the automatic dust cleaning device of the butterfly valve is simple and convenient in dust cleaning operation.
Description
Technical field
The utility model relates to a kind of automatic ash removing device of butterfly valve, is applicable to carry the more large-scale pipeline valve of dust-laden in the high-temperature gas in the industrial sulphuric acid production.
Background technique
Carrying high-temperature flue gas pipeline valve commonly used in the gas washing in SA production is hard sealing flange formula stainless steel butterfly valve, and material is G/F
4, adopt macrotype butterfly valve to carry and have the following advantages as flue gas:
(1) compact structure, structure length is short, and volume is little, and is in light weight.
(2) fluid resistance is little, and during standard-sized sheet, the valve base channel valid circulation area is bigger, thereby fluid resistance is less.
(3) open-close convenient is rapid, and adjusting function is good, and the butterfly plate half-twist both can be finished keying.Can the grading control flow by the angle of swing that changes butterfly plate.
(4) keying moment is less, because rotating shaft both sides butterfly plate is subjected to the medium effect equal substantially, and the direction of generation torque is opposite, thereby opens and closes more laborsaving.
But because dust-laden is many in the flue gas during smelting, to contain saturated water amount big, during the dirt mud of high speed flue gas was carried, after dirt and the moisture mixing, viscosity was big, easily is bonded on butterfly plate and the valve body.The gap is minimum between hard seal butterfly valve butterfly plate and valve body, and when a large amount of dirt mud combine in valve body (mainly in valve body lower portion), resisting moment is big in the valve switch process, causes the valve stuck phenomenon easily.
The model utility content
The utility model purpose is the easy stifled phenomenon of card when carrying the high flue gas of dust loading at traditional large-scale hard seal butterfly valve, provide a kind of simple in structure, be convenient to operate, can remove automatically dirt mud and avoid the valve that causes the valve card stifled.
The technical solution of the utility model is: a kind of automatic ash removing device of butterfly valve, the dust stratification case is installed in the butterfly valve body bottom, worm conveyor is installed in this dust stratification case, this worm conveyor is driven by motor and speed reducer, bottom at described dust stratification case is provided with ash removing port, and this ash removing port bottom is installed and closed the wind discharge valve.
The utility model rotates by the worm conveyor that fractional electric motor drives in the dust stratification case, utilize the impeller of worm conveyor to scrape, the dust in the valve rotated to the dust stratification lower box part after getting rid of the dust stratification in the lower valve, periodic cleaning is fallen to get final product, reached automatic removing dirt mud and avoided causing the stifled purpose of valve card, and deashing is simple to operation.
The flue gas that application of the present utility model is not limited in the gas washing in SA production is carried valve, is applicable to that also other have dust-laden, gas that impure amount is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, Fig. 2, a kind of automatic ash removing device of butterfly valve, dust stratification case 2 is installed in the butterfly valve body bottom, in this dust stratification case 2 worm conveyor 1 is installed, this worm conveyor 1 is driven by motor 4 and speed reducer 5, be provided with ash removing port 3 in the bottom of described dust stratification case 2, these ash removing port 3 bottoms are installed and are closed the wind discharge valve.The space of valve valve plate rotation will be considered in the size of described worm conveyor 1 and mounting point, valve plate can not be blocked; The big I of dust stratification case 2 determines that according to dust-laden in the flue gas and periodic cleaning time dust-laden is many in the flue gas, the periodic cleaning cycle is long, and then the dust stratification casing is long-pending suitably amplifies, few, the periodic cleaning cycle weak point of dust-laden in the flue gas, then the dust stratification casing amass can suitably do little; Start worm conveyor and discharge valve during deashing; The power equipment of worm conveyor--motor 4, its model is unsuitable excessive, selects according to the resisting moment of worm conveyor; Valve body, worm conveyor, dust stratification case, ash removing port material are selected for use according to working medium and are determined.
Claims (1)
