Abstract
The utility model discloses a hand-operated lifting device for a flue duct cover of a boiler dust remover. The hand-operated lifting device comprises a dust remover air room, a flue duct cover and a flue duct lifting cylinder; the flue duct cover is mounted in the dust remover air room; the flue duct lifting cylinder comprises a piston and a piston rod connected with the piston; the piston rod is connected with the flue duct cover; two hand-operated lifting rods are symmetrically arranged on the flue duct cover and are positioned on two sides of the flue duct cover lifting cylinder; and a handle is arranged at the top end of each hand-operated lifting rod. When the hand-operated lifting device comes to service, in the case of emergencies like power failure and lack of compressed air, the flue duct cover can be manually pulled through the hand-operated lifting rods within five minutes, so that the flue duct is kept unobstructed, and normal operation of a boiler is not influenced.
Description
Technical field
The utility model relates to a kind of boiler dust remover Chimney cover hand hoisting device.
Background technology
Boiler adopts the filter bag type pulse dust collector, is divided into five air compartments, and each air compartment has a Chimney cover.Close the Chimney cover of an air compartment successively and carry out deashing through robot control system(RCS).When certain air compartment carried out deashing, Chimney cover was closed, and compressed air is jetted to cloth bag through pulse valve, caused the shake deashing.The control mode of Chimney cover is: through turnover of solenoid control compressed air and trend, piston drives the piston rod in the cylinder, controls the switching of Chimney cover then.Open when at least two air compartment Chimney covers, could guarantee that flue is unobstructed, boiler normally moves.
There is following drawback in existing deduster: as run into power failure, stop emergency such as compressed air, cylinder is ineffective, and Chimney cover is closed voluntarily, can't open.Cause flue obstructed, cause blowing out, have a strong impact on production.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, and a kind of boiler dust remover Chimney cover hand hoisting device is provided, and it is at Chimney cover bilateral symmetry two hand hoisting bars of welding and handgrip is installed; Make gland and insert seal felt and guarantee sealing; After the utility model comes into operation, run into power failure, when stopping emergency such as compressed air, can be through the artificial pull-up Chimney cover of hand hoisting bar within 5 minutes; The assurance flue is unobstructed, does not influence boiler and normally moves.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of boiler dust remover Chimney cover hand hoisting device, comprises that deduster air compartment, Chimney cover and Chimney cover promote cylinder, and said Chimney cover is installed in the deduster air compartment; Said Chimney cover promotes cylinder and comprises piston and the piston rod that is connected with piston, and said piston rod is connected with Chimney cover; Be symmetrically arranged with two hand hoisting bars on the said Chimney cover, said hand hoisting pole pair is claimed to be arranged at the both sides that Chimney cover promotes cylinder, and the top of hand hoisting bar is provided with handle.
Said hand hoisting bar and deduster air compartment junction are provided with gland, are filled with seal felt in the said gland.
Said Chimney cover promotes cylinder and is provided with magnetic valve.
The utility model is two hand hoisting bars of symmetry welding on Chimney cover; When Chimney cover promotes the cylinder operate as normal with the Chimney cover free lifting; Run into power failure, when stopping emergencies such as compressed air; Can guarantee that flue is unobstructed through the artificial pull-up Chimney cover of hand hoisting bar within 5 minutes, not influence boiler and normally move.The utility model is inserted seal felt and has been solved the wind chamber sealing problem through gland and in gland.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of boiler dust remover Chimney cover hand hoisting device, comprises that deduster air compartment 1, Chimney cover 2 and Chimney cover promote cylinder 3, and said Chimney cover is installed in the deduster air compartment; Said Chimney cover promotes cylinder and comprises piston 4 and the piston rod that is connected with piston 5, and said piston rod is connected with Chimney cover; Be symmetrically arranged with two hand hoisting bars 6 on the said Chimney cover, said hand hoisting pole pair is claimed to be arranged at the both sides that Chimney cover promotes cylinder, and the top of hand hoisting bar is provided with handle 7.
Said hand hoisting bar and deduster air compartment junction are provided with gland 8, are filled with seal felt 9 in the said gland.
Said Chimney cover promotes cylinder and is provided with magnetic valve 10.
The utility model is two hand hoisting bars of symmetry welding on Chimney cover; When Chimney cover promotes the cylinder operate as normal with the Chimney cover free lifting; Run into power failure, when stopping emergencies such as compressed air; Can guarantee that flue is unobstructed through the artificial pull-up Chimney cover of hand hoisting bar within 5 minutes, not influence boiler and normally move.The utility model is inserted seal felt and has been solved the wind chamber sealing problem through gland and in gland.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
