Abstract
The invention discloses a biomass two-stage helical feeding device which consists of a first-stage helical conveyor, a second-stage helical conveyor and a buffer tank arranged between the first-stage and second-stage helical conveyors, wherein the first-stage helical conveyor inputs biomass fuel into the buffer tank; the second-stage helical conveyor conveys the biomass fuel into a biomass reactor; and a back stop device is mounted at the output tail end of the first-stage helical conveyor and used for preventing the material and gas from being reversely returned to a conveying channel of the first-stage helical conveyor under the high-temperature positive-pressure effect of the reactor so as to prevent the material and gas in the reactor from being reversely returned to the conveying channel of the first-stage conveyor under the high-temperature positive-pressure effect and from scattering in air to cause air pollution.
Description
Technical field
The invention belongs to material transfer equipment, specifically relate to a kind of two-stage screw feed arrangement that is used to carry biomass fuel.
Background technology
In gasifying biomass and liquefaction reaction production, the equipment of past reaction vessel transfer the fuel generally is feeding screw.In process,, be in the operation under positive pressure environment because the inside reactor temperature is high with biomass fuel input reactors such as density smaller particles type, loose type, powder types; The inlet point of reaction vessel has determined self can't form sealed environment, and fire gases (medium) is revealed through feeding screw easily, causes fire hazard; Simultaneously, biomass fuel, is produced dust and flies away in the air to the powder storehouse by blowback; Cause abominable working environment, foul air.
Summary of the invention
In order to solve the problem that prior art exists, the living beings two-stage screw feed arrangement that the present invention provides the reverse returning charge of a kind of anti-malleation, anti-gas to reveal.
In order to realize above purpose; Technical scheme of the present invention is following: a kind of living beings two-stage screw feed arrangement; Baffle-box by one-level auger loader, deuterostrophies conveyer and they are provided with is between the two formed; The one-level auger loader is imported biomass fuel to baffle-box; Deuterostrophies conveyor biomass fuel to biological matter reactor, the output of said one-level auger loader is terminal install one be used to stop material and gas under the reactor high temperature positive pressure by the backstop in the reverse transfer passage that returns the one-level auger loader.
Further, said backstop comprises the swing type cover plate of a sealing one-level conveyer porthole, and this swing type cover plate is installed on the one-level conveyor porthole versatilely.
A rotary support is fixed on top, said one-level conveyor porthole, and said swing type cover plate is movably arranged in the rotary support.Said rotary support connects a transition piece versatilely, is connected between transition piece and the swing type cover plate.
Said backstop comprises the swing type cover plate of a sealing one-level conveyer porthole, and this swing type cover plate is lifted on the medial surface of baffle-box roof versatilely.
The area of said swing type cover plate equates with one-level conveyor channel cross-sectional area at least.
Said one-level conveyor porthole sees to have the angle of inclination from the longitudinal cross-section.The periphery of said one-level conveyor porthole is provided with bumper ring, and the roof of said baffle-box offers access hole.
The bottom of said baffle-box is built-in with setting gauge.
Compared with prior art; This practical output end with the one-level auger loader places baffle-box; And output end backstop is set; Thereby stoped material and gas in the reaction vessel under the high temperature positive pressure by in the reverse transfer passage that returns the one-level auger loader, avoid flying away in the air and cause aerial contamination.
Description of drawings
Fig. 1 is the structural representation of first embodiment.
Fig. 2 is the structural representation of backstop.
Fig. 3 is the swing type cover plate open mode figure of backstop.
Fig. 4 is the structural representation of second embodiment.
The specific embodiment
First embodiment
As shown in Figure 1, the two-stage screw feed arrangement is made up of one-level auger loader 1, baffle-box 5 and deuterostrophies conveyer 8.Between one-level auger loader 1 and the deuterostrophies conveyer 8 baffle-box 5 is set, is used to store biomass fuels such as a certain amount of density smaller particles type, loose type, powder type.One-level auger loader 1 is in the top of deuterostrophies conveyer 8.Two augers is formed by motor 12, transfer passage and screw shaft assembly 14, and screw shaft assembly 14 comprises screw shaft and is enclosed in the axial helicallobe of spiral, and screw shaft assembly 14 is installed in the transfer passage, and motor 12 drives 14 rotations of screw shaft group.The motor output end of deuterostrophies conveyer 8 is provided with flexible seal ring 7, forms sealing, effectively avoids gas leakage.
As shown in Figure 2, backstop 3 is by bearing 9, transition piece 10 and swing type cover plate 11.Transition piece 10 is grooved, and the one of which end is connected bearing 9 versatilely and can rotates around the fulcrum of bearing 9, and the other end connects swing type cover plate 11.The area of swing type cover plate 11 is identical with transfer passage 13 port sectional areas at least.Seeing that from the longitudinal cross-section of transfer passage its top is shorter in length than down edge lengths, make swing type cover plate 11 be covered in the port of transfer passage 13 obliquely, promptly is under the effect of gravity, makes the swing type cover plate be closely attached on the port of transfer passage 13.Swing type cover plate 11 bevelled angle [alpha] are between 60～85 °, preferably 80 °.
During the work of two-stage screw feed arrangement, biomass fuel gets into from inlet point in the transfer passage of one-level auger loader, and along with the driving of motor, screw shaft rotates, and is kept in by quantitative being conveyed in the baffle-box of helicallobe.When biomass fuel arrives the transfer passage mouth of one-level auger loader, back down the swing type cover plate of backstop and open (as shown in Figure 3), blanking.When stopping material conveying or material deficiency, swing type cover plate by gravity resets, and is close to the transfer passage mouth at any time, thereby the transfer passage mouth is sealed.Biomass fuel drops down onto the level 2 buffering auger loader, is input in the reaction vessel by deuterostrophies buffering conveyer.
Second embodiment
As shown in Figure 4, different with first embodiment is, backstop 3 is not to be fixed on the transfer passage, but with bearing 9 upside-down mountings of backstop 3 on the roof of baffle-box 5.This structure can realize barrier functionality equally, and benefit is during the maintenance of one-level auger loader, can not receive the obstruction of backstop.
