Description

Bag-type dew dust remover

Technical field

The present invention relates to a kind of deduster, but relate in particular to the sack cleaner that a kind of dewfall is used.

Background technology

At present, known sack cleaner must not use under moist dewfall state, and this is confessed both at home and abroad, after its reason is cloth bag dewfall humidity, be collected the dust that gets off and stick with paste on filtrate and can't remove, cause filtrate airtight, can not use to filtration was lost efficacy.

Summary of the invention

In order to overcome " bag dedusting can not dewfall use " this recognized techniques difficult problem, the invention provides a kind of sack cleaner, this deduster can solve sticks with paste a bag problem, can be used under the dewfall state.

The technical solution adopted for the present invention to solve the technical problems is: the sack cleaner that is provided, it comprises main box, lower box, blast pipe and shutter, air outlet, discharge pipe and go out air door, the blowback air port, reverse-blow pipe and blowback air door, card between main box and lower box, the last end closure that is positioned at main box is after the many cloth bags that spring hangs over its lower ending opening on the top board and communicates with lower box with the inside of card connection, design has the external diameter that is positioned at cloth bag to be slightly less than encircling every a plurality of ashes of scraping that move up and down that equate between the upper and lower along center line of cloth bag internal diameter, be positioned at scrape on the ash ring axial line with connection strap with scrape ash and encircle the grey bar of scraping that connects firmly, be positioned at lower box with bolt be elongated to a plurality of joining supports of grey bar of scraping of lower box, be positioned at the cylinder that connects with support with bolt below the support, cylinder is fixed by bolts on the cylinder seat that connects firmly with lower box.

It more than is inward flow filtration-type, when being used for outside filtering type, the deduster structure has more a upper box, increase again in the cloth bag skeleton is arranged, card between upper box and main box, be positioned at the many cloth bags that the inside on the card communicates with upper box that are fixed on of main box, design have be positioned at the outer internal diameter of cloth bag be slightly larger than the skeleton external diameter be slightly less than again cloth bag when heaving external diameter be enclosed within cloth bag outer along the cloth bag center line between the upper and lower every a plurality of ash rings of scraping that move up and down that equate, scrape ash ring outside between cloth bag in the space with connection strap with adjacent to the grey grey bar of scraping that connects firmly that encircles, be positioned at below the cloth bag with bolt and a plurality of joining supports of grey bar of scraping that are elongated to below the cloth bag, be positioned at the cylinder that connects with support with bolt below the support, cylinder is fixed by bolts on the cylinder seat that connects firmly with lower box.

When dewfall is used, cloth bag and the dust of accepting are moist, after using certain hour or resistance to reach certain value, then off-line promptly breaks away from dedusting cloth bag and dust is carried out drying, therefore ad hoc have dry wind blast pipe and an air door, for quickening drying, utilize the hot gas that hot surface distributed that produces flue dust stove self to insert dry airduct with pipeline, become dry hot gas, behind cloth bag and dust usefulness dry-heat air bone dry, start cylinder and move back and forth, carry out blowback simultaneously, at this moment cloth bag shrinks, filtrate and dust just contact with the ash ring of scraping that moves up and down, and dry dust just is scattered immediately, owing to scrape the double action of ash ring and blowback, the dust that is attached on the cloth bag inwall just breaks away from the ash bucket that cloth bag falls into lower box, finishes deashing process.

A deduster can only be: dedusting → drying → deashing → dedusting → drying → deashing, the dust removal process of the interruption of such reciprocation cycle so want continuous dedusting, wants two dedusters to unite use at least, forms unit.

Use for making at least two deduster combined continuous dewfall, ad hoc meter is made an automaton.

Advantage and good effect: the dedusting unit of two or multi-platform combined use, a dried offline deashing is wherein arranged, all the other normal dedustings have realized that the continuous dewfall of bag dedusting uses, and have broken through the forbidden zone that the bag dedusting can not dewfall be used.

Embodiment

Embodiment 1

Specific embodiments of the present invention 1 are consulted Fig. 1, Fig. 2, by main box 10, card 20, lower end and card fix its upper end through spring be suspended on 4 on the top board arrange the bag 8, lower box 4, blast pipe 17, discharge pipe 16, reverse-blow pipe 11 constitutes the main body of deduster, intended diameter is 15cm, length is that spacing uniformly is housed in the cloth bag 8 of 2m at interval is that the external diameter of 50cm is that pump 4 of 14.6cm scrape ash ring 9, scraping the steel wire of ash ring 9 usefulness diameter 0.4cm makes, each is scraped ash ring and connects firmly being positioned at 4 connection straps 19 and scrape ash and encircle scraping on the grey bar 5 of 9 centers, every lower end of scraping grey bar 5 is elongated in the lower box 4, be fixed by bolts on the support 3 that blocks dust does not fall, support 3 links to each other with the expansion link that dustproof telescopic is housed of following

cylinder

2,2 in cylinder is formed and is scraped apparatus for ash on the cylinder seat 1 that connects firmly with lower box.

The dewfall operational version also comprises with cloth bag with attached to the dust on the cloth bag carries out mechanism dry and oven dry, it by dry airduct 7, dry air door 6 and relative shutter 18, go out air door 15, blowback air door 12 is formed; Dry wind in the dry airduct of this programme adopts dry-heat air.Hot air source is to utilize the heat energy that produces flue dust stove self kiln external surface, wraps one deck thermal insulation board at 0.5 meter, outside of its outer surface, is connected with dry airduct with pipeline, becomes dry-heat air.

After cloth bag 8 dewfall use certain hour or resistance to be elevated to certain value, close shutter 18, stop dedusting, enter drying program, at this moment open dry air door 6, go out air door 15 and stay open state, blowback air door 12 keeps closed condition, dry-heat air just enters and passes cloth bag like this, and with cloth bag and dust oven dry, the water vapour after the evaporation enters discharge pipe 16 with air-flow through air outlet 14 and enters atmosphere.

Behind cloth bag and the dust bone dry, close dry air door 6 and go out air door 15, open blowback air door 12 and shutter 18, start cylinder 2 simultaneously and drive and scrape ash ring 9 and pump, at this moment because entering of blowback wind shunk cloth bag, the dry dirt of cloth bag inwall touches scrapes ash ring 9 and just hangs down immediately, blowback wind blows off dry dirt again and falls into ash bucket behind the filter cloth, and purge gas enters behind the cloth bag because of pressure is higher than air intake pressure, just enters blast pipe 17 through air inlet.

Scrape ash ring 9 50cm at interval, the cylinder stroke is 60Ccm, guarantees all to scrape, and does not stay the dead angle.

After deashing is finished, close blowback air door 12, open out air door 15, the closed condition of the air door 6 that keeps dry and the open mode of shutter 18 are recovered dust removal process, finish a circulation.

The separate unit deduster can only be interrupted work, and dedusting continuously wants two All-China Federation of Taiwan Compatriots to close use at least, just can reach the purpose of continuous dedusting, i.e. dry deashing, and another normal dedusting, two chaptrels change jobs, and this programme uses two.

Fig. 3, Fig. 4, Fig. 5 are that the running status figure when using closes in two separate units and two All-China Federation of Taiwan Compatriots.Abscissa is the time, represents with t; Ordinate is represented with q for handling air quantity.

Fig. 3 is first state that is in normal dedusting at the very start, and the time arrives the A point since 0, and the used time of dedusting is 1 hour; Stop dedusting then, carry out drying, arrive the B point from the A point, the used time is 58 minutes, and cloth bag and dust be bone dry, just enters next program---dust out; At this moment owing to scrape the double action of ash ring 9 and blowback, can very fast dust be disposed, to the C point, the used time has only 2 minutes from the B point, again owing to being reverse blowing, so at this moment the processing air quantity of deduster is a negative value; Deashing finishes, and drops into dedusting again, and to the D point, circulation is gone down like this from the C point.

Fig. 4 is second, is initially located in drying stage, has used 58 minutes from 0 to A; Used 2 minutes and remove dust from A to B, drying and deashing are shared 1 hour; Entering the dedusting stage then, is 1 hour from B to the C time; And then to enter drying stage be that 58 minutes and deashing stage are 2 minutes from D to E from C to D; Enter the dedusting stage again after deashing is finished, circulation is gone down like this.

When Fig. 5 represented that use is closed by two All-China Federation of Taiwan Compatriots, dedusting was carried out continuously.

Embodiment 2

Filter and outer filter were two kinds in sack cleaner was divided into by filter type, and outside filtering type deduster structure has more a upper box, and increasing again in the cloth bag has skeleton, and scheme 1 is an inward flow filtration-type, and 2 of schemes are outside filtering type, and promptly dust is collected on the outer surface of cloth bag.The concrete structure of this programme 2 is seen Fig. 6 and Fig. 7, is with the difference of scheme 1: scrape the outside that ash ring 9 is enclosed within cloth bag 8.

The design framework external diameter is that 14cm is (because of outside filtering type cloth bag when the dedusting shrinks, must there be skeleton that cloth bag is propped up), diameter when cloth bag is heaved is 15cm, length is that to put spacing at interval uniformly be that the internal diameter of 50cm is that pump 4 of 14.6cm (skeleton external diameter at this moment is less than and scrapes about ash ring internal diameter 0.6cm) scrape ash ring 9 in the outside of the cloth bag 8 of 2m, scraping the steel wire of ash ring 9 usefulness diameter 0.4cm makes, each is scraped 4 connection straps 19 of ash ring 9 usefulness and connects firmly scraping on the grey bar 5 in the gap between the cloth bag of scraping the ash ring outside, every lower end of scraping grey bar 5 is elongated in the lower box 4, be fixed by bolts on the support 3, support 3 links to each other with the expansion link of following

cylinder

Dust removal process is with scheme 1, and cloth bag 8 shrank when difference was dedusting, rather than heaved.

Dry run is with scheme 1, and difference is that dry-heat air sees through cloth and enters in the bag outside cloth bag, rather than from the cloth bag thoroughly outside cloth bag.

Deashing process is with scheme 1, and cloth bag 8 was heaved when difference was deashing, rather than shrinks.Diameter when heaving because of cloth bag 8 is 15cm, and the internal diameter of scraping ash ring 9 is 14.6cm, and less than the diameter of cloth bag 8, at this moment the outer surface of cloth bag 8 all greyly encircles 9 and contacts with scraping, and the dust full scale clearance is fallen.

Continuously during dedusting, also will at least two All-China Federation of Taiwan Compatriots close use, its running status and process are seen Fig. 3, Fig. 4 and Fig. 5 with scheme 1.
