Description

Hot mill bag-type dust collection device
Technical field:
The present invention relates to hot-rolling mill technical field, be specifically related to hot mill bag-type dust collection device and dust collection method.
Background technology:
Hot rolling (hot rolling) is for cold rolling, and cold rolling is the rolling carried out below recrystallization temperature, and hot rolling is exactly the rolling carried out more than recrystallization temperature.
Hot rolling significantly can reduce energy consumption, reduces costs.During hot rolling, plastic deformation is high, and resistance of deformation is low, greatly reduces the energy ezpenditure of flow of metal.Hot rolling can improve the process industrial art performance of metal and alloy, and the coarse grain by as-cast condition is broken, and remarkable crack healing, reduces or eliminates casting flaw, changes as-cast structure into Deformation structure, puies forward heavy alloyed processing characteristics.Hot rolling adopts large ingot casting usually, and heavy reduction rolling not only increases production efficiency, and creates condition for improving mill speed, the serialization realizing the operation of rolling and automation.
Sack cleaner is a kind of dry type dust filtration device.It is applicable to trap tiny, dry, non-fiber dust.Filter bag adopts the filter cloth of weaving or nonwoven felt to become, the filtration of fabric is utilized to filter dusty gas, after dusty gas enters sack cleaner, large, the heavy dust of particle, because the effect of gravity settles down, fall into ash bucket, containing the gas compared with fine dusts when by filtrate, dust, by detention, makes gas be purified.The efficiency of dust collection of general filtrate is not high enough.
Filtering dust-arrester comprises sack cleaner and gravel bed filter, filter course made by the filter bag that the former utilizes organic fiber or inorganic fibre fabric to make usually, and the particle of filter course many employings different-grain diameter of the latter, as compositions such as quartz sand, river sand, haydite, slags.
What attend by powder repetition is attached to filter bag outer surface, and powder bed constantly thickens, and sack cleaner Resistance Value also increases thereupon; Pulse valve diaphragm sends instruction, and when left and right is flooded, pulse valve is opened, and the compressed air in high pressure gas bag has led to, if do not have dust or be small enough to certain degree, mechanical ash removing work can quit work.
The many employings of bag-type dust structure of existing hot-rolling mill burn plate deduster, winter, and entering inner steam can freeze, and need often to change, the cost of replacing adds a lot; Also have a kind of dedusting structure of filter kernel, shaping by macromolecular compound, production difficulty is large, and processing cost is high, and the energy consumption of the sintered plate of this two class is large, and the effect of dedusting is general.
Mostly bag-type dust equipment is flush system on the market, and the space taken is large, step-by-step according to how to complete dedusting to operation, inefficiency.
Summary of the invention:
The object of this invention is to provide a kind of hot mill bag-type dust collection device, its reasonable in design, adopt the dust absorbing structure of superposing type, saved and taken up room, and the flow process of dedusting is short, good dedusting effect, cost is low.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises fume trap cover above hot-rolling mill entrance fume trap cover, hot-rolling mill, outlet fume trap cover, sandblasting fume trap cover, inlet (dust contained gas), casing, revolving valve, filter bag, pulse valve, injection tube, air-purifying chamber, pure qi (oxygen) outlet; Hot-rolling mill entrance fume trap cover, outlet fume trap cover, sandblasting fume trap cover are successively set on the side of casing from top to bottom, above hot-rolling mill, fume trap cover is arranged on the side of hot-rolling mill entrance fume trap cover, outlet fume trap cover, sandblasting fume trap cover are all connected with inlet (dust contained gas), several filter bag is provided with in casing, the bottom of casing is provided with revolving valve, and the top of filter bag is connected with injection tube, and one end of injection tube is provided with pulse valve, injection tube is embedded in air-purifying chamber, and one end of air-purifying chamber is provided with pure qi (oxygen) outlet.
As preferably, described filter bag is elasticity filter bag, increases it and filters and flexibility during deashing.
As preferably, described inlet (dust contained gas) place is provided with flow apron, and the stream top of baffle plate is fixedly connected with the top of casing.
As preferably, the bottom of described flow apron is provided with baffle plate, baffle plate and casing is fixed during deashing, improves the efficiency of deashing.
When the present invention operates, by fume trap cover above hot-rolling mill entrance fume trap cover, hot-rolling mill and sandblasting fume trap cover trap dust, dust enters casing through inlet (dust contained gas), then is discharged from pure qi (oxygen) outlet by clean air through the filtration of filter bag and the purification of air-purifying chamber; Filter bag can expand when deashing, all dusts of inside can be cleaned out like this.
Beneficial effect of the present invention: its reasonable in design, adopt the dust absorbing structure of superposing type, saved and taken up room, and the flow process of dedusting is short, good dedusting effect, cost is low.
