Abstract
Offset biomass rotatory feeder valve and feeding method.Common rotatory feeder valve is since compartment is in the heap full with substance behind feeding zone, and continuing rotation in blade, extremely bite can be formed because of the spilling of material by agreeing with place with shell.Present invention composition includes: feed valve chest (1), revolving vane central axis is installed in the feed valve chest, revolving vane (2) are installed on the revolving vane central axis, the revolving vane end is connect with flexible sealing fin (3), the flexible sealing fin is tightly contacted with the feed valve chest, there is blanking port on the feed valve chest, the side of revolving vane uplink is arranged in the blanking port, and blanking port and the feed valve housing junction are equipped with transitional slope.The present invention is fed for biomass rotatory feeder valve.
Description
Technical field:
The present invention relates to a kind of offset biomass rotatory feeder valve and feeding methods.
Background technique:
With flourishing for biomass power generation industry, the straw burning technology as technological core passes through R&D institution and correlation
The effort of enterprise has improved gradually maturation by largely improving, but front-furnace feeding link matched with combustion apparatus is always
It is a main restricting factor.
First biomass power generation project of China's construction is due to no any experience, and mating feeding system is with foreign technology
Directly based on the invalidated testing program of introduction and designed, designed, China's biomass fuel can not be coped with due to introducing technology
Expect the statuses such as generally existing kind is miscellaneous, moisture is high, impurity is more, pretreatment degree difference, mostly occur the shadows such as stuck, blocking after putting into operation
The problem of ringing feed continuity, even system stability.
Common rotatory feeder valve since compartment is in the heap full with substance behind feeding zone, blade continue rotation to and shell
Bite can be formed because of the spilling of material by agreeing with place.
Summary of the invention:
The object of the present invention is to provide a kind of offset biomass rotatory feeder valve and feeding methods.
Above-mentioned purpose is realized by following technical scheme:
A kind of offset biomass rotatory feeder valve, composition includes: feed valve chest, is equipped in the feed valve chest
Revolving vane central axis, is equipped with revolving vane on the revolving vane central axis, the revolving vane end and flexible
Diaphragm seal connection, the flexible sealing fin tightly contact with the feed valve chest, have on the feed valve chest
The side of revolving vane uplink is arranged in blanking port, the blanking port, and blanking port is set with the feed valve housing junction
There is transitional slope.
The offset biomass rotatory feeder valve, the revolving vane blade quantity are 4-8.
The offset biomass rotatory feeder valve, the corresponding feed valve shell nozzle angle of the blanking port
Degree is 40-80 °.
The offset biomass rotatory feeder valve, the corresponding extended corner of blanking port slope section are 15-30 °.
A kind of feeding method using offset biomass rotatory feeder valve described in one of claim 1-4,
The revolving vane and flexible sealing fin of offset biomass rotatory feeder valve be mounted on feed valve chest in, revolving vane around
The central axis rotation of revolving vane, the sector space that every two blade is formed is as a compartment, and biomass material is through feed valve
Blanking port on shell is fallen into the compartment of revolving vane, and with the rotation of revolving vane, compartment is rotated to discharge port, biomass
Material is discharged through discharge port, loops back and forth like this realization continuous-feeding.
The utility model has the advantages that
The sector space that every two blade of the present invention is formed as a compartment continuous-feeding, blanking port position must guarantee each every
Storehouse cannot fill entire compartment behind feeding zone in rotation；Blanking port and housing junction are equipped with transitional slope, avoid paddle
The meeting point of leaf and shell gets too close to feeding zone, and material is caused to cause bite at meeting point；Revolving vane end and flexibility
Diaphragm seal connection, flexible sealing fin are tightly contacted with shell, guarantee feed valve sealing.Meanwhile flexible sealing fin is with stronger
Plasticity avoids diaphragm seal and shell meeting point that bite occurs.
Present system is simple and reliable, and feed is stablized, and is not susceptible to bite problem；Material applicability is wide, be suitable for rice husk,
Biomass block, biological particles etc.；System sealing is good, is suitable for the higher positive pressure feeding system of sealing requirements.

Attached drawing 1 is structural schematic diagram of the invention.
Attached drawing 2 is the working principle of the invention figure one.
Attached drawing 3 is the working principle of the invention figure two.
