Description
Technical field
The present invention relates to a kind of mining device, particularly relate to a kind of diplopore without plate sealing angle ash-removing valve.
Background technology
The returning charge object of CFBB sends carbon unburnt in returning charge ash back in bed after-flame, to improve boiler combustion efficiency, reduces flying dust and large slag phosphorus content, maintains the goods fluid in stove simultaneously.Under normal circumstances, returning charge ash does not need discharge, because corresponding certain load, circulating ratio is certain.In actual motion, in some cases, such as ature of coal is very poor, and material returning device temperature and bed temperature continue slowly to decline, then need regularly to bleed off returning charge ash, to improve bed temperature, keeps boiler operatiopn to stablize.Conventional ash-removing valve door is manual or electric gate valve, putting the normal appearance outwards grey phenomenon of spray and bite phenomenon in grey process, because the grey temperature of returning charge generally reaches 800-950 DEG C, therefore easily causes the generation of security incident.
Summary of the invention
The object of this invention is to provide a kind of safe and reliable, effective diplopore without plate sealing angle ash-removing valve.
For achieving the above object, the technical solution used in the present invention is:
A kind of diplopore is without plate sealing angle ash-removing valve, comprise upper plate and lower plate, upper plate and lower plate are symmetrical arranged up and down, upper plate and lower plate are hinged and connected at the two afterbody by bolt, it is characterized in that: on upper plate, excavation has upper hole, and upper hole place is airtight is communicated with dust leg, and dust leg is positioned at above upper plate, in lower plate, excavation has lower opening, and upper hole and lower opening are corresponding up and down; When upper plate overlaps with lower plate, upper hole and lower opening stagger mutually, and when upper plate and lower plate stagger, upper hole overlaps mutually with lower opening.
According to described diplopore without plate sealing angle ash-removing valve, it is characterized in that: the front of described lower plate and one of them side is airtight is connected with lower seal plate, the trailing edge of described upper plate and another side relative with lower seal plate is airtight is connected with upper sealing panel.
According to described diplopore without plate sealing angle ash-removing valve, it is characterized in that: described bolt coat is equipped with spring, spring is positioned at above described upper plate or below described lower plate.
According to described diplopore without plate sealing angle ash-removing valve, it is characterized in that: described upper plate tail end is fixedly connected with limited block, limited block is corresponding with described lower seal plate.
According to described diplopore without plate sealing angle ash-removing valve, it is characterized in that: described lower plate or described lower seal plate are fixedly connected with jug.
This valve is divided into upper and lower two parts, upper plate has hole, lower plate has lower opening, and upper hole is identical with the aperture of lower opening, and aperture, upper hole is consistent with dust leg external diameter, employing is tightly connected, upper plate and lower plate afterbody adopt bolt flexible fastening, and lower plate can be rotated centered by bolt, and when upper and lower two parts overlap, this valve is closed completely, otherwise open, when lower plate is opened, afterbody limited location block blocks.
Compared with common ash-removing valve door, the present invention mainly contains following advantage:
1, adopt upper and lower sealing plate fitted seal, good sealing effect, do not run ash, leak ash, processing safety is high.
2, switching manipulation is simple, and middle without plate, high-temperature region thermal expansion is even, and opening angle is little, stability of rotation between upper plate and lower plate, decreases bite phenomenon, and operability is high, practical.
3, processing and manufacturing cost is low, expense is few, can processing and manufacturing voluntarily, and economic feasibility is high.
4, change traditional flashboard type structure, improve the wearability of valve, thus extend the service life of valve.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
A kind of diplopore is without plate sealing angle ash-removing valve, as shown in Figures 1 to 5, comprise upper plate 3 and lower plate 6, upper plate 3 and lower plate about 6 are symmetrical arranged, and upper plate 3 and lower plate 6 are hinged and connected at the two afterbody by bolt 10, and on upper plate 3, excavation has upper hole 2, upper hole 2 place is airtight is communicated with dust leg 1, dust leg 1 is positioned at above upper plate 3, and in lower plate 6, excavation has lower opening 7, and upper hole 2 is corresponding with lower opening about 7; When upper plate 3 overlaps with lower plate 6, stagger mutually with lower opening 7 in upper hole 2, and when upper plate 3 staggers with lower plate 6, upper hole 2 overlaps mutually with lower opening 7.
In the present embodiment, the front of described lower plate 6 and one of them side is airtight is connected with lower seal plate 4, the trailing edge of described upper plate 3 and another side relative with lower seal plate 4 is airtight is connected with upper sealing panel 11.Be set with spring 8 outside described bolt 10, spring 8 is positioned at above described upper plate 3 or below described lower plate 6.Described upper plate 3 tail end is fixedly connected with limited block 9, and limited block 9 is corresponding with described lower seal plate 4.Described lower plate 6 or described lower seal plate 4 are fixedly connected with jug 5.
