The U-shaped sealing part and the S-shaped sealing part are in labyrinth sealing to be capable of effectively controlling fine clinker powder to leak from the grate bed, and the clearance t exists between the S-shaped sealing part and the U-shaped sealing part, and cold air in an air chamber can be blown onto the grate bed through the clearance to cool the clinker; and in addition, the sealing device is connected to the longitudinal beams which have no relative movement with grate plates and horizontal pushing plates so as to avoid relative abrasion, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of cooling machine longitudinal sealing device, relates in particular to sealing device between a kind of row that are used for step-by-step movement cooling machine movable grate.
Background technology
The cooling machine it is generally acknowledged and experienced the development of four generations as the main process equipment of cement plant grog firing system.Wherein, do not have the material of leakage, low wearing and tearing are maximum characteristics of novel cooling machine of the 4th generation.The 4th generation cooling machine adopts step-by-step movement (walking floor type) movable grate; The vertical apportion of movable grate of carrying grog to use is done the reciprocating motion of " one insertion and three withdrawals "; Wherein, There is relative motion to combing in row between the bed, and clinker is revealed to the slit of combing between the bed from row easily, needs the longitudinal sealing device.
Hermetically-sealed construction is referring to Fig. 1 between the row of existing step-by-step movement cooling machine movable grate, and wherein 1 for being listed as to the bed of combing, and 3 is the comb plate; Between longitudinal sealing 2 and the horizontal scraping wings 4, form a coffin.During production, static grog is preserved in the coffin the inside, is used for reducing the wearing and tearing of motion grog to the comb plate; But in this coffin, longitudinal sealing 2 beyonds are to move, and the grog here is not static fully; Therefore between longitudinal sealing 2 and comb plate 3 and the horizontal scraping wings 4, there is relative motion, can weares and teares; Reduce comb plate 3, laterally the life-span of scraping wings 4 and longitudinal sealing 2; After longitudinal sealing 2 wearing and tearing, the internal clearance can become greatly, influences sealing effectiveness, leaks material easily in addition.
The utility model content
The utility model is to provide a kind of long service life, sealing device between the row of the step-by-step movement cooling machine movable grate of good sealing effect.
The technical scheme of the utility model is following:
Sealing device between a kind of row of step-by-step movement cooling machine movable grate; Said movable grate comprises the longeron of multiple row relative motion; The sealing device is arranged between the two adjacent row longerons; Said sealing device comprises S shape seal and U-shaped seal, and one in a side of U-shaped seal and the said adjacent two row longerons is connected, and the opposite side of U-shaped seal inserts in the groove that an arc-shaped side edges of S shape seal forms; In another arc-shaped side edges of S shape seal and the adjacent two row longerons another is connected, and the gap between said S shape seal and the U-shaped seal is t.
In order to reach better sealing effectiveness, anti-leak-stopping material adopts labyrinth seal between S shape seal and the U-shaped seal.
Adopt bolt to be connected between seal and the longeron, seal is dismountable to be installed between the two adjacent row longerons, is convenient to install and replacing.
In the course of work; In order to protect the bolt between seal and the longeron not to be damaged; In S shape seal and U-shaped seal, be equipped with gusset, gusset and seal are wholely set, and wherein the gusset in the U-shaped seal and the gap of S shape seal arc-shaped side edges are t; Make the cold wind in the air compartment to blow on the bed of combing the cooling grog through the gap.
The preferable range of above-mentioned clearance t is 0≤t≤10mm.
The utility model will comprise that the sealing device of U-shaped seal and S shape seal is designed to labyrinth seal; And the gap between S shape seal and the U-shaped seal is t; The sealing device not only can effectively be controlled the grog fine powder and leak down from the bed of combing; Cold wind in the air compartment can blow on the bed of combing the cooling grog through the gap simultaneously; In addition, sealing device is connected between the two adjacent row longerons, itself and comb plate; Laterally there is not relative motion between the scraping wings; Avoid the relative wear between them, greatly reduced wear extent, prolonged the service life of comb plate, horizontal scraping wings and sealing device.
