The front edge and one side edge of the lower plate are connected with a lower seal plate in a sealed manner, and the tail edge of the upper plate and the other side edge opposite to the lower seal plate are connected with an upper seal plate in a sealed manner; the bolt is sleeved with a spring which is located above the upper plate or below the lower plate; the tail end of the upper plate is fixedly connected with a stop block which corresponds to the lower seal plate; and the lower plate or the lower seal plate is fixedly connected with a handle. The valve is divided into an upper part and a lower part, is closed when the upper and lower part coincide, and is open otherwise.
Description
Technical field
The utility model relates to a kind of mining device, relates in particular to a kind of diplopore without plate sealing angle ash-removing valve.
Background technology
The returning charge object of CFBB is to send unburnt carbon in returning charge ash back to a bed interior 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 is 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, material returning device temperature and bed temperature continue slow decreasing, need regularly to bleed off returning charge ash, to improve bed temperature, keep boiler operatiopn stable.Conventional ash-removing valve door is manual or electric gate valve, putting the normal outwards grey phenomenon of spray and the bite phenomenon of occurring in grey process, because the grey temperature of returning charge generally reaches 800-950 ℃, therefore easily causes the generation of security incident.
Summary of the invention
The purpose of this utility model 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 adopted in the utility model 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, the airtight dust leg that is communicated with in upper hole place, dust leg to be positioned at upper plate top, in lower plate, excavation has lower hole, and Yu Xia hole, upper hole is corresponding up and down; In the time that upper plate overlaps with lower plate, stagger mutually in Yu Xia hole, upper hole, and in the time that upper plate and lower plate stagger, Yu Xia hole, upper hole overlaps mutually.
, it is characterized in that: the front of described lower plate and the airtight lower seal plate that is connected with of one of them side, the trailing edge of described upper plate and another side airtight the be connected with upper sealing panel relative with lower seal plate without plate sealing angle ash-removing valve according to described diplopore.
, it is characterized in that: described bolt coat is equipped with spring without plate sealing angle ash-removing valve according to described diplopore, spring is positioned at above described upper plate or below described lower plate.
, it is characterized in that: described upper plate tail end is fixedly connected with limited block without plate sealing angle ash-removing valve according to described diplopore, limited block is corresponding with described lower seal plate.
, it is characterized in that: described lower plate or described lower seal plate are fixedly connected with jug without plate sealing angle ash-removing valve according to described diplopore.
This valve is divided into upper and lower two parts, on upper plate, have upper plate, in lower plate, have lower hole, the aperture in Yu Xia hole, upper hole is identical, 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 in the time that upper and lower two parts overlap, this valve is closed completely, otherwise open, when lower plate is opened, afterbody limited location piece blocks.
Compared with common ash-removing valve door, the utility model mainly contains following advantage:
1, adopt upper and lower sealing plate fitted seal, good sealing effect, does not run ash, leaks ash, and 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, and stability of rotation between upper plate and lower plate has reduced bite phenomenon, and operability is high, practical.
3, processing and manufacturing cost is low, expense is few, processing and manufacturing voluntarily, and economic feasibility is high.
4, changed traditional flashboard type structure, improved the wearability of valve, thereby extended the service life of valve.
