The bottom size and the cinder conveyer of described ship shape ash bucket are complementary.

The two ends and the both sides of described ship shape ash bucket all tilt.

The two ends of described ship shape ash bucket and both sides are all vertical.

The two ends of described ship shape ash bucket tilt and both sides are vertical.

The two ends of described ship shape ash bucket are vertical and both sides tilt.

The utility model can further reduce the steel unit consumption, reduces floor space, reduces operating cost, improve operating efficiency, compare with existing little ash bucket pulse bag type dust collector, can reduce investment outlay about 45%, reduce floor space about 50%, save operational and administrative expenses about 40%, equipment year, the running job rate was near 100%, was applicable to single ash bucket single chamber, single ash bucket multicell, many ash buckets single chamber and single-row or biserial deduster.

Description of drawings

Structural representation when Fig. 1 adopts the tapered ash bucket of platform (two buckets, two Room) for the utility model;

Structural representation when Fig. 2 adopts ship shape ash bucket (a pipeful of two Room) for the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---pulse jetting deashing device 2---access door

3---escape pipe 4---filter bag

5---cage bone 6---support frame

7,7 '---ash bucket 8---air inlet pipe

9---unloading valve 10---cinder conveyer

Embodiment one

As shown in Figure 1, this especially big ash bucket pulse bag type dust collector mainly is made up of deduster main body, ash-transmission system and electric control gear, wherein main part has pulse jetting deashing device 1, access door 2, escape pipe 3, filter bag 4, cage bone 5, filter bag chamber and support frame 6 thereof, the ash bucket 7 that is supported by underframe is the tapered ash buckets of platform, air inlet pipe 8, unloading valve 9 are installed in the tapered ash bucket of platform bottom, scrape template cinder conveyer 10 and are installed in the ash bucket outside and are connected with unloading valve 9.

The processing air quantity of this deduster is 13000 cubic metres of per minutes, 1.0 meters of filtration velocity per minutes, be that filter bag filter area summation is 13000 square metres, owing to adopted the structure of two buckets, two Room, therefore the filter area summation of each tapered ash bucket correspondence is 6500 square metres, the dust mean concentration of ash-laden gas is every cubic metre 5 gram, dust pile proportion is 1 ton every cubic metre, the amount of dust that produces of this deduster 24 hours totally 93.6 as calculated, promptly 93.6 cubic metres, the dischargeable capacity of each tapered ash bucket is equal to or greater than 50 cubic metres can satisfy the requirement of unloading once ash in 24 hours.

Ash-laden gas is entered by air inlet pipe 8 during use, and enter in the filter bag from the outside of filter bag 4, dust is blocked on the filter bag outer surface, flue gas after being purified enters atmosphere by escape pipe 3, regularly blow off in ash bucket 7 by pulse jetting deashing device 1 attached to the dust on the filter bag outer surface, earlier the dress of automobile, train or other means of transport ash container is aimed at the port of export of cinder conveyer 10 when unloading ash, start cinder conveyer earlier, the back starts unloading valve, after unloading ash and finishing, close unloading valve earlier, treat to close cinder conveyer again after dust in the cinder conveyer is given out light.

Embodiment two

As shown in Figure 2, two ends of its ash bucket 7 ' be and both sides are careen shape ash bucket all, and corresponding two filter bag chambers scrape that template cinder conveyer 10 is installed in ship shape ash bucket the inside and near the bottom, unloading valve 9 is installed in the port of export of cinder conveyer 10, and other structure is identical with embodiment one with technology.

The filter bag filter area summation of this ship shape ash bucket correspondence is 13000 square metres, 24 hours ash amount still is 93.6 tons, because the ship shape ash bucket has made full use of among the embodiment one space between two platform taper ash buckets, therefore equal altitudes, etc. under the situation at inclination angle, dischargeable capacity than single taper ash bucket is twice many, be more suitable for transporting grey number of times in doing the grey storehouse of storage, be beneficial to reduce.In addition, platform taper ash bucket is in order to unload ash smoothly, and the inclination angle on its four limit must be not less than 60 degree, and the ship shape ash bucket is not limit by this.

Ash-laden gas is entered by air inlet pipe 8 during use, and enter in the filter bag from the outside of filter bag 4, dust is blocked on the filter bag outer surface, flue gas after being purified enters atmosphere by escape pipe 3, attached to the dust on the filter bag outer surface by pulse jetting deashing device 1 regularly blow off to ash bucket 7 ' in, earlier the dress of automobile, train or other means of transport ash container is aimed at the unloading valve 9 of the cinder conveyer port of export when unloading ash, start unloading valve earlier, restart cinder conveyer, after unloading ash and finishing, close cinder conveyer earlier, close unloading valve again.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
