Abstract
The utility model discloses a kind of sealing device of cylindrical shape sack cleaner, comprise revolution deashing mechanism and the bottom dedusting ash silo of cylindrical shape sack cleaner, the affixed back-up ring of encorbelmenting of level on the outer circle wall of revolution deashing mechanism, back-up ring of encorbelmenting is made up of angle ring, angle ring has downward vertical guide, on the dedusting ash bulkhead of bottom level affixed packing ring, affixed the internal layer rubber gasket sheet matched with revolution deashing mechanism outer circle wall on the bottom dedusting bulkhead being positioned at packing ring top, by the gap sealing between revolution deashing mechanism and bottom dedusting cabin, affixed outer layer rubber sealing plate on packing ring, match with the plummet face of back-up ring of encorbelmenting in the top of outer layer rubber sealing plate.The utility model is rational in infrastructure, can improve the dynamic sealing effect between the revolution deashing mechanism of cylindrical shape sack cleaner and bottom dedusting ash silo, reduces dedusting inleakage, improves dust removing effects, reduces the pollution to environment.
Description
Technical field
The utility model belongs to the cylindrical shape sack cleaner hermetically-sealed construction, particularly a kind of sealing device of cylindrical shape sack cleaner that reduce inleakage.
Background technology
Current part fiber bag precipitator is cylinder type sack cleaner, and the type deduster structure is cylinder type, little compared with rectangle deduster floor space, and investment cost can reduce, use winding-up pipeline and pulse valve few.The circular general top of deduster is steel platform, dedusting ash silo, filter bag, rotating frame (roof system) and rotary pulse deashing mechanism, and bottom is ash-transmission system and concentrates storage ash silo.Rotary pulse deashing mechanism operation principle is: drive roof system and revolution deashing mechanism to produce gyration by drive unit, in turning course, when the purging arm of deashing mechanism is corresponding with the cloth sack that need clean, by rotary encoder sender to pulse valve, pulse valve obtains signal and jets, and realizes removing dust and clearing ash function.
But its shortcoming is, the roof system of dust remover roof and rotary pulse deashing mechanism are integral solder steel constructions, support by rotating guide wheel, because need to rotate, certain gap (generally meeting is between 10-20mm) is there is between roof system and fixed mechanism such as revolution deashing mechanism and bottom dedusting ash silo etc., this structure certainly exists larger air leak rate of air curtain, greatly reduces dedusting actual air volume; Also can cause larger noise when leaking out in addition, cause environmental noise pollution to this region.
Summary of the invention
The purpose of this utility model is the sealing device providing a kind of cylindrical shape sack cleaner, it is rational in infrastructure, the dynamic sealing effect between the revolution deashing mechanism of cylindrical shape sack cleaner and bottom dedusting ash silo can be improved, reduce dedusting inleakage, improve dust removing effects, reduce the pollution to environment.
The purpose of this utility model is achieved in that a kind of sealing device of cylindrical shape sack cleaner, comprise revolution deashing mechanism and the bottom dedusting ash silo of cylindrical shape sack cleaner, the affixed back-up ring of encorbelmenting of level on the outer circle wall of revolution deashing mechanism, back-up ring of encorbelmenting is made up of angle ring, angle ring has downward vertical guide, on the dedusting ash bulkhead of bottom level affixed packing ring, affixed the internal layer rubber gasket sheet matched with revolution deashing mechanism outer circle wall on the bottom dedusting bulkhead being positioned at packing ring top, by the gap sealing between revolution deashing mechanism and bottom dedusting cabin, affixed outer layer rubber sealing plate on packing ring, match with the plummet face of back-up ring of encorbelmenting in the top of outer layer rubber sealing plate.
The utility model adds a set of double-layer back hermetically-sealed construction transition to cylindrical shape sack cleaner, affixed back-up ring of encorbelmenting on the outer circle wall of revolution deashing mechanism, on dedusting ash bulkhead level affixed packing ring, internal layer rubber slab affixed on the dedusting ash bulkhead on packing ring top is by the gap sealing between revolution deashing mechanism and dedusting ash silo, and outer layer rubber sealing plate affixed on packing ring matches with the outer wall of back-up ring of encorbelmenting.
Above device can realize double-layer sealing structure, and the air intake duct that leaks out can become S type narrowed flow path, greatly reduces air imbibed quantity.Decrease dedusting inleakage, improve efficiency of dust collection.
Good effect of the present utility model: improve the dynamic sealing effect between top and the bottom, reduces dedusting inleakage.Improve actual dedusting air quantity, improve dust removing effects.Lower dedusting fan power consumption, reduce electric cost.Reduce environmental noise pollution.The utility model is rational in infrastructure, improves the dynamic sealing effect between the revolution deashing mechanism of cylindrical shape sack cleaner and bottom dedusting ash silo, decreases dedusting inleakage, improve dust removing effects, decrease the pollution to environment.
Accompanying drawing explanation
Be further stated the utility model below in conjunction with accompanying drawing, Fig. 1 is sectional structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of sealing device of cylindrical shape sack cleaner, as shown in Figure 1, comprise revolution deashing mechanism and the bottom dedusting ash silo of cylindrical shape sack cleaner, the affixed back-up ring 3 of encorbelmenting of level on the outer circle wall 1 of revolution deashing mechanism, back-up ring 3 of encorbelmenting is made up of angle ring, angle ring has downward vertical guide, on bottom dedusting ash bulkhead 2 level affixed packing ring 8, affixed the internal layer rubber gasket sheet 4 matched with revolution deashing mechanism outer circle wall 1 on the bottom dedusting bulkhead 2 being positioned at packing ring 8 top, by the gap sealing between revolution deashing mechanism and bottom dedusting cabin, affixed outer layer rubber sealing plate 5 on packing ring 8, match with the plummet face of back-up ring 3 of encorbelmenting in the top of outer layer rubber sealing plate 5.
Internal layer rubber gasket sheet 4 arranges clip plate 6, is bolted and clip plate 6 and internal layer rubber gasket sheet 4 are fixed on bottom dedusting bulkhead 2.
Outer rubber gasket sheet 5 arranges outer plate 7, is bolted and outer plate 7 and outer layer rubber sealing plate 5 are fixed on packing ring 8.
