1 one kinds of chimney gauze screens of embodiment deduster

Referring to Fig. 1, this deduster is generally used the iron and steel thin sheet manufacturing by control of dust section [6] and dedusting section [3] and loam cake [2] formation, and each section connects with bolt.Control of dust section [6] is a cone empty in, and up big and down small, bottom surface is swash plate [11], and swash plate is ash hole [8] bottom, and external ash discharging pipe is to the ground ashpit.The stovepipe [7] that joins with boiler passes from swash plate [11] central authorities, and the mouth of pipe is higher than swash plate, makes the dust that drops on the swash plate [11] can not enter stovepipe [7], but can not exceed the upper surface.Upper surface and dedusting section [3] are joined, and the dedusting section has square shell, and the length and width height is 45 * 45 * 200～250cm.Inside is equipped with 8～12 dedusting plates [5], and these dedusting plates are less than the shell cross section.Level separated by a distance is staggered between [5] one and one of the onesize dedusting plates, forms crooked exhaust gases passes between piece and piece, and the area of the area of this passage and chimney inlet tube [7] is basic identical.Dedusting plate [5] is made with the gauze screen bound edge, mesh 4 * 4mm.Be connected with hinge on same one side of shell, can to sagging 90 degree, rotating from the plane, dedusting plate [5] when being horizontal by 3 limits of wall have with edges of boards isometric use angle safe edge made of iron.The effect one of safe edge is to surpass horizontal level when preventing to spur dedusting plate [5], the 2nd, prevent that flue gas from passing through from dedusting plate [5] edge, lowers efficiency.Every dedusting plate [5] all is connected with same iron chains [4], moves on the iron chains, and dedusting plate is lifted flat, and is in running order.Iron chains [4] moves down, and dedusting plate [5] falls down, and can remove long-pending dust onboard.Loam cake [2] is a downward cone at a gulp, and bottom and dedusting section [3] are joined, top connect one with import stovepipe thick outlets [1] such as [7].Iron chains [4] upper end that links to each other with dedusting plate [5] is connected steel cable [10], join with ground upper lever [12] by the pulley [9] that is installed on the loam cake [2], make things convenient for the people to operate, dedusting plate [5] can be fixed on horizontal level during tension, dedusting plate is fallen down, remove dust.Dedusting section [3] shell has door with dedusting plate [5] correspondence position on one side, can open the dust of sweeping under accumulating not on the dedusting plate [5] in case of necessity.

The working condition of deduster is such: flue gas enters control of dust section [6] from the pipe [7] of bottom, because volume enlarges, gas flow rate slows down, and the dust of big grain is fallen on the swash plate [11].At this moment gas can be walked two roads by dedusting section [3], and one is up along the exhaust gases passes between plate, because passage is crooked, flue dust collides with gauze screen [5] in advancing, and speed slows down and drops on the gauze screen; Another is up by gauze screen [5], because the filtration of mesh, only the dust less than mesh could pass through.At last, flue gas is discharged through loam cake [2] outlet.Through after a while, dust is deposited on the dedusting plate [5] gradually from lower to upper, and aeration resistance increases, and at this moment just need loosen iron chains [4], and dedusting plate [5] is fallen down, and allows the dust of deposition fall on the swash plate [11], discharges through outlet again.Strain steel cable [10] then, make dedusting plate [5] get back to level.The user can determine how many days draw steel cable No. one time voluntarily according to the content of flue dust, to guarantee efficiency of dust collection.
