Abstract

The utility model relates to a double-layer circle bag dust collector which is combined by a plurality of double-layer circular filter bags. The ash is blown reversely by a blower fan, the dust collector adopts the mode that a shifter and the chain transmission are adopted to realize three-state ash removal, and adopts a special filter bag compacting device. The utility model overcomes the defects of the present bag type dust collector which has high energy consumption, large space occupation, bad dust removing effect, etc. The dust collector with two-layer round bag is an ideal dust collector with high efficiency.

Description

Dust cleaner with two layer round bag

A kind of sack cleaner.

The sack cleaner kind is a lot of both at home and abroad, with the immediate known technology of the utility model be the double-deck single-filtering sack cleaner of China LFS type, this deduster is by the square filter bag combination of a plurality of bilayers, use the blower fan reverse gas cleaning, belong to " filtration "---" deashing " two condition purge mode, the energy consumption height, floor space is big, and ash-removal effect is poor.

The purpose of this utility model provides the high-efficiency cloth bag deduster of characteristics such as having energy consumption is low, floor space is little, ash-removal effect is good, saving steel.

Double-deck circle bag dust collector is formed (see figure 1) by upper box, middle casing, ash bucket and deashing mechanism.Upper box comprises loam cake, air-purifying chamber, double-layer air pipe, double-deck air-valve, filter bag hold down gag and card; Middle casing comprises filter bag, spring skeleton, air inlet and access door; Ash bucket comprises filter bag carriage and ash exhauster; Deashing mechanism comprises double-deck air-valve, star-like decelerator, chain and shift fork.

The utility model deduster adopts double-layer circular filter bag structure (see figure 2), at pouch of a sack back boxing, outer big cloth bag is supported by the spring cage bone, the internal layer cloth bag is fixed on the suspension hook, because interior filter and outer filter combine, make deduster arrange that in unit item indexs such as density and fillter section volume density are better than domestic and international multiple sack cleaner, dwindled floor space, reduced steel quantity consumption.Filter bag hold down gag (see figure 5), the filter bag O shape rubber ring that puts suitable for reading, embed card, above again the cloth bag trim ring being pressed in, with fastening handle cloth bag is fixed between fastening trim ring and the card, has so just changed the fixing way of boring on card, reduced the probability that leaks dirt, make dust collector efficiency stable, and it is simple and easy to do to change cloth bag.

The deashing mechanism of deduster is pressed the system design of three condition deashing, makes filter bag be in " filtration " " deashing ", " static " three kinds of different conditions respectively.Existing sack cleaner purge mode is " filtration " and " deashing " two states, the deashing time is short, filter bag is cleared up the dust that gets off and also is not deposited to ash bucket and just is adsorbed on the filter bag again, produced " absorption again " phenomenon, promptly increase equipment resistance, influenced ash-removal effect again.The utility model deduster has designed the length of chain link stopper, drive the link stopper motion by reductor, the shift fork of in succession filtration and blowback air-valve is stirred in the gap, make filter bag afterwards at " filtration ", " deashing ", increased " static " state, make the dust of clearing up that the time of a natural subsidence to ash bucket be arranged, avoided " absorption again " phenomenon of dust.

Shortcomings such as energy consumption height, the floor space that double-deck circle bag dust collector has overcome existing sack cleaner is big, ash-removal effect difference are a kind of desirable efficient sack cleaners.

After dusty gas enters deduster by middle casing air inlet, filter through inside and outside double-layered filtering bag respectively, purified gas is discharged by exhaust blower by the air-purifying chamber of inflow upper box in space between the inside and outside filter bag. When resistance of the filter bag rose to certain value, deduster began sub-room cleaning, drove chain by decelerator, by the shift fork on the double-deck air-valve of chain-driving, valve for air exhaust is closed again, the back-blowing valve is opened, air-flow enters space between the inside and outside filter bag, the dust that is attached on the filter bag is shaken off down, closed again the back-blowing valve, make by the bag chamber of deashing to remain static, dust falls into ash bucket smoothly, after static a few minutes, start valve for air exhaust, begin again filtration condition.
