Description
Technical field
This utility model belongs to waste incineration and generating electricity device technique field, is specifically related to a kind of fire grate sealing air sealing device.
Background technology
In prior art, the sealing air of fire grate seals structure and generally comprises the sealing air cavity being arranged on fire grate front end, sealing air cavity top is installed with block and lower block, stuffing box, uses soft sealing material to make filler, compress the sealing structure of filler with nut or gland in stuffing box.
The sealing air of above-mentioned fire grate seals structure and there arises a problem that in actual moving process, when fire grate connecting rod moves reciprocatingly, is not linear reciprocation simply, but can with certain angle of inclination.Existing sealing air seals structure owing to maintaining static so that fire grate drives link motion limited angle, when the angled change of link motion, seals structure and can produce gap with connecting rod contact position, cause that sealing effectiveness declines, do not reach requirement.
Utility model content
For the problems referred to above, this utility model aims to provide the fire grate sealing air sealing device of a kind of good sealing effect.
This utility model solves the technical scheme of problem: a kind of fire grate sealing air sealing device, including the sealing air cavity being arranged on fire grate front end, sealing air cavity wall is provided with sealing air entrance, sealing air cavity top is provided with pressure cover, this pressure cover is the hollow cap of bottom-open, gap is there is between pressure cover top and sealing air cavity top, form a cavity, pressure cover top has the first through hole, the slide block being sized larger than the first through hole and can moving freely in cavity it is provided with in described cavity, its center is provided with the second through hole, described slide block is fixed with annular packing case around the second through hole, airtight and watertight padding it is filled with in stuffing box, airtight and watertight padding gland compresses, gland is provided with third through-hole；
Described sealing air cavity top has waist-shaped hole, and the aperture of the first through hole is more than stuffing box external diameter；
Described first through hole, the second through hole, third through-hole and waist-shaped hole are respectively provided with identical central axis.
In such scheme, connecting rod is driven to be connected through the first through hole, the second through hole, third through-hole and waist-shaped hole with fire grate, in driving the reciprocating process of fire grate, waist-shaped hole can allow for connecting rod has certain angle to deflect, slide block moves in cavity with the reciprocating motion of connecting rod, is formed and seals in real time.
Preferably, it is provided with packing ring bottom described stuffing box and between slide block.
Concrete, described airtight and watertight padding is carbon fibre dipping politef.
The upper block that cross section is horizontal L-shaped and lower block, upper block and lower block that described pressure cover includes being symmetrically installed dock, and upper block and lower block have the arc gap of symmetry at joint, are spliced to form the first through hole after docking.
Of the present utility model it has the advantages that:
1. sealing device of the present utility model is owing to devising slide block structure so that driving connecting rod to move with angle variation pattern in reciprocatory movement, action is smooth and easy.
2. this utility model slide block moves back and forth with the motion of connecting rod, it is ensured that seals structure and does not produce gap with the contact position driving connecting rod, it is ensured that the sealing blast of sealing air cavity is more than grate wind chamber primary air pressure, and First air is not revealed, good sealing effect.
