Abstract
The utility model relates to a feeding device, in particular to a built-in spiral biomass feeder. A storage bin is positioned above a conical feeder in which a charging device is arranged, wherein biomasses are caused to continuously enter into the conical feeder through the charging device, and then the biomasses in the conical feeder are caused to continuously enter into a combustion device or a gasification device through a reducing packing auger; and the storage bin, the charging device and the feeder are integrated, wherein a charging rod of the charging device is dismountable, and the biomasses in the storage bin are uniformly stirred due to the charging rod. The built-in spiral biomass feeder achieves the purpose of causing the biomasses to continuously enter into the conical feeder, and avoids the problems of bridging, winding, and the like of the biomasses in a hopper; the built-in spiral biomass feeder adopts the mode of conical feeding so that the biomasses in the conical feeder are compressed due to the continuously reduced circulation area, thereby greatly increasing the stacking density; and simultaneously pressure isolation and air locking between the feeder and a combustion device or the gasification device are achieved, thereby avoiding the influencing on feeding by preventing blowby between the feeder and the combustion device or the gasification device.

Technical field
The utility model relates to a kind of feeding unit, particularly a kind of combustion unit or reinforced built-in biomass screw feeder of gasification installation of being applicable to.
Background technology
China's biomass energy is very abundant, and only agro-ecology matter waste material stock number such as agricultural crop straw is 7 * 10
8T/h is equivalent to 3.5 * 10
8The t standard coal, forestry residuum about 1.5 * 10
8T/h amounts to standard coal about 0.7 * 10
8T.The utilization of biomass energy has realized CO
2The balance that absorbs and discharge, the decarburization in the future more strict for reply requires to have very powerful competitive power.Gasifying biomass can be the energy of GOOD TASTE with low-grade Conversion of energy, is a kind of optimal selection of biomass utilization.The type of furnace that present domestic gasifying biomass adopted generally comprises fixed-bed gasification furnace and fluidized-bed gasification furnace.But fixed-bed gasification furnace is because throughput is little, tar output is big, gasification efficiency is low and can not carry out shortcoming such as large-scale industrial production and do not used on a large scale.And fluidized-bed gasification furnace since gasification efficiency height, raw material wide accommodation, synthetic gas tar content are low and can the heavy industrialization application etc. advantage become the preferred manner of gasification.
In the biomass gasification process, must guarantee that raw material enters gasification installation continuously, and require feeder and gasification installation strict seal.Biomass have short texture, tap density is little, fibre content is many, fiber is elongated, characteristics such as adhesion make and are easy to occur problems such as scaffold and winding in the reinforced process each other, influence the continuous conveying of biomass, make the poor air-tightness between gasification installation and the feeder, influence the works better of feeder.The bad meeting of sealing causes a series of problem between feeder and the gasification installation: when system is in the negative pressure operation, can cause air to enter combustion unit or gasification installation by feeder, influence the whole flow field of combustion unit or gasification installation inside, cause the operation of vapourizing furnace off-design direction, when system was in operation under positive pressure, the gas of combustion unit or gasification installation can be overflowed by feeder, made material be difficult to enter vapourizing furnace, the material that might ignite when serious, initiation fire.
Existing gasification installation feeder is because biomass short texture, tap density are little, and fibre content is many, fiber is elongated, factor such as adhesion each other, makes problem such as the scaffold that exists, winding and can't realize continuous charging in the process of feeding in raw material.This has limited the application of gasifying biomass aspect to a great extent, even the gasifying biomass that can't normally realize.
Summary of the invention
The purpose of this utility model is in order to overcome the various defectives of existing fed technology, a kind ofly can avoid that material stops up, the novel built-in biomass screw feeder of material wide accommodation continuously feeding but disclose.
The utility model is realized by following technical approach: funnel shaped feed bin and tapered tube are at right angles combined, and tapered tube is positioned on the sidewall of feed bin, and the two inside communicates; Vertically the blanking axle is positioned at feed bin, and its upper end is furnished with a vertical motor, and the lower end is provided with the blanking bar, rotates by the vertical blanking axle of vertical driven by motor, and material is pushed taper feeder continuously; Taper feeder is positioned at tapered tube, the one end is furnished with cross motor, the other end connects reducing strand cage, driving taper feeder by cross motor rotates, biomass are compressed owing to passage constantly diminishes after entering tapered tube, tap density increases, and the lock wind of having realized feeder and combustion unit or gasification installation has simultaneously avoided the gas of combustion unit or gasification installation to influence reinforced by the feeder effusion every pressure; At the top of feed bin charging opening and gate valve are set.
Described blanking bar is irregular layout, realizes omnibearing material toggling and blanking continuously.
The tapering of described taper feeder and the angle of horizontal direction are: 0 °＜θ＜60 °.
The pitch of described reducing strand cage diminishes from left to right gradually, and variation range is: 20mm＜Δ P＜450mm.
The increase scope of the tap density of described biomass in tapered tube is: 20%＜Δ ρ＜50%.
The utility model has the following advantages compared with the prior art:
What 1, the utility model adopted is the taper feeding manner, biomass enter after the taper feeder owing to circulation area is constantly dwindled and is compressed, tap density increases greatly, realized simultaneously combustion unit or gasification installation and feeder every pressing lock wind, avoided collaborating and influence charging between combustion unit or gasification installation and the feeder.
2, taper feeder of the present utility model is positioned at feed bin inside, and biomass directly enter taper feeder through blanking device, have solved the blanking difficulty, problem that can not continuous charging.
3, blanking device of the present utility model, taper feeder and feed bin are integrated, blanking device is positioned at the top of taper feeder, blanking device and taper feeder are all in feed bin inside simultaneously, blanking distance and space have been reduced, avoid problems such as the scaffold of biomass and winding, helped continuous charging.
