Background
The bag-type dust collector is a standard configuration in modern blast furnace smelting production, and the lift valve is an important component of the bag-type dust collector and mainly comprises a cylinder, an electromagnetic reversing valve, a valve plate and a pull rod. Wherein the valve plate is arranged usually between air-purifying chamber and export box, plays the effect of blocking the flue gas, and the poppet valve is the closed structure of pushing down usually, drives the promotion and the action of pushing down of pull rod control valve plate through the cylinder. When pushing down, the poppet valve plate is closed and is blocked the flue gas completely to make the air-purifying chamber off-line, let the pulse valve utilize compressed air to carry out the jetting deashing to the filter bag under the state that the flue gas stops, the deashing is accomplished the back, and the valve plate is mentioned, and the poppet valve is open mode, and the flue gas normally gets into the air-purifying chamber and filters.
The cylinder of traditional poppet valve passes through fastener lug fixation on sack cleaner roof, cylinder telescopic link and pull rod front end can get into the flue gas passageway when pushing down the action in, with gas and the dust contact that contains corrosivity, it rusts even the phenomenon of scale deposit caking to appear corroding easily, can make the sealing washer wearing and tearing of cylinder bottom serious after the long-term operation, lead to the cylinder gas leakage, the valve plate can be because of promoting the not enough whereabouts under self action of gravity of strength, cause the poppet valve closed, air-purifying chamber closes to export box passageway, the flue gas can not circulate, increase dust remover negative pressure, cause the potential safety hazard. In addition, the pull rod and the valve plate connected mode of traditional poppet valve are bolted embedded connection, and bolted connection is unstable easily to appear after long-term the use, receives the flue gas influence easily and rotatory aversion even drops and can not close completely when the valve plate pushes down, plays the effect of blocking the flue gas, leads to equipment to appear leaking out the phenomenon of leaking out, is unfavorable for equipment steady operation, also leads to the production environmental protection accident easily.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problems that a cylinder in a traditional bag-type dust collector lifting valve is easy to damage and a valve plate is easy to rotate and fall off are solved.
The utility model provides a sack cleaner poppet valve, including cylinder and valve plate, the cylinder drive the valve plate realizes that the air-purifying chamber is opened and close, include:
the distance increasing structure is used for increasing the distance between the air cylinder and the top plate of the bag-type dust collector;
the pull rod penetrates through the top plate, one end of the pull rod is connected with the air cylinder, and the other end of the pull rod is connected with the valve plate in a detachable connection and fixed connection mode;
the limiting rod is arranged on the side part of the valve plate and used for preventing the valve plate from rotating;
and the dust cover is sleeved on the pull rod.
Under the action of the distance increasing structure, the piston rod cannot enter the dust removal chamber when extending out, and under the combined action of the dust cover, dust is effectively isolated, so that the phenomenon that a gasket at the bottom of the cylinder is abraded and air leaked due to corrosion, rusting and scaling of the piston rod and the pull rod, and a valve plate falls off is avoided; the detachable connection is realized by selecting a fastener to position and fixedly install the pull rod and the valve plate, and the fixed connection can be realized by selecting electric welding to reinforce the valve plate and prevent the valve plate from falling off; the limiting rod is used for preventing the valve plate from rotating and avoiding the incomplete closing of the air purifying chamber; to sum up, the utility model discloses not only make the cylinder not fragile, still avoided the valve plate rotation to drop to reduce the maintenance frequency, practiced thrift the cost.
Furthermore, the distance-increasing structure is a support, the lower end of the support is fixedly connected with the top plate, and the upper end of the support is fixedly connected with the cylinder. The design has simple structure and low manufacturing cost.
Further, the pull rod with still be connected with sleeve pipe and flange in proper order between the valve plate, the sleeve pipe cup joints the pull rod lower extreme, the sleeve pipe with be equipped with two at least strengthening ribs between the flange. So set up, the pull rod is connected more firmly with the valve plate.
Furthermore, the dust cover is provided with two sections which are respectively sleeved with the parts of the pull rod, which are positioned at the upper side and the lower side of the top plate. So set up, the pull rod is covered completely to the dust cover, has improved dustproof effect.
