Abstract
The utility model discloses a shaftless spiral feeder for biomass. A motor directly drives a shaftless spiral blade; the thickness of the spiral blade is 10-30mm, and the space between the shaftless spiral blades is 260-460mm; the cross section of a trough is U-shaped, and a lining plate is overlaid on the bottom of the trough; and the trough is provided with a temperature sensor and a fire extinguisher. The shaftless spiral blade is adopted to eliminate influence of the central shaft on the conveyed biomass fuel, so as to prevent coiling and blocking. In addition, as the space between the spiral blades is increased and the thickness of the spiral blade is increased, the spiral blade can resist the resistance of hard blocks without deformation, and motor load is balanced. Thus, the shaftless spiral feeder is suitable for conveying biomass fuels, such as block fuel, large-particle fuel, loose fuel, barks, roots and the like, and the conveying amount of the shaftless spiral feeder is increased by about half.
Description
Technical field
The utility model belongs to material transfer equipment, specifically relates to a kind of batcher of carrying biomass fuel to biomass boiler.
Background technology
In the biomass fuel feeding device,, usually can use screw(-type) feeder for biomass boiler front-furnace feeding system.Screw(-type) feeder is generally by the conveyer body, and charging and discharging mouth and drive unit are formed, and conveyer body is wherein formed by rotating shaft, helical blade and material are poor.Rotating shaft is installed on the bearing block at hopper two ends through bearing.When biomass fuel adds from charging aperture, along with motor-driven rotatable shaft is rotated, fuel is promoted to advance by helical blade, thereby accomplishes to the operation of boiler feed.Yet,, all have influence on the conveying effect like hardness, length, shatter value, impurity content etc. because there is difference in the biomass fuel quality.For example, some biomass fuel hardness height, longer dimension, size are irregular, and contain impurity such as stone in the fuel, make conveyer in the helical feed process, often get stuck, and rotation is obstructed, and causes the flight deformed damaged; Also have strong, loose biomass fuel such as bark, the stalk etc. of some viscosity to be wrapped in easily in the rotating shaft, cause the motor overload scaling loss.
The utility model content
In order to solve the problem that prior art exists, the utility model provides the living beings that a kind of feeding is smooth and easy, wearability is good not have a screw(-type) feeder.
In order to realize above purpose; The technical scheme of the utility model is following: a kind of living beings do not have a screw(-type) feeder; Comprise motor, helical blade and hopper, said motor direct-drive does not have the axial screw blade, and the thickness of said helical blade is 10～30mm; The spacing of said helical blade is 260～460mm, and the cross section of said hopper takes the shape of the letter U.
Further, the bottom of said hopper is equipped with liner plate, and temperature sensor and fire extinguisher are installed on the said hopper.
The diameter of said helical blade discharge end and pitch are greater than the diameter and the pitch of its feed end.
The variation of said helical blade diameter and pitch is gradual change type or sudden change formula.
Said helical blade diameter and pitch sudden change formula be changed to multistage sudden change.
Comprise two motors with identical parameters, said two motors directly drive no axial screw blade respectively.
Said helical blade is parallel to be provided with.
The interlaced setting of said helical blade.
Said helical blade is the multithreading helical blade.
Said helical blade is two thread helical blades.
Compared with prior art, owing in hopper, be provided with no axial screw blade, eliminated central rotating shaft and do not taken place to twine and jam carrying the influence of biomass fuel, making; And, make helical blade can resist the resistance of lump because the pitch space of helical blade increases and the thickness of helical blade thickens, and can not produce distortion, motor load is balanced.Therefore, the utility model is applicable to the conveying of biomass fuels such as bulk, bulky grain, loose fuel, bark and tree root, and its conveying capacity has increased about half.
Description of drawings
Fig. 1 is not for there being the structural representation of axle screw(-type) feeder.
Fig. 2 is not for there being the cross section structure sketch map of axle screw(-type) feeder.
Fig. 3 is two structural representations that do not have the axle screw(-type) feeder.
Below, in conjunction with specific embodiment and accompanying drawing the utility model further is described in detail.
The specific embodiment
As shown in Figure 1, do not have the axle screw(-type) feeder and form by motor 1, hopper 3, helical blade 7 and liner plate 4.It is 7.5Kw that motor 1 adopts cycloidal-pin wheel decelerator power, rotating speed 8.3rpm, and through frequency control, the conveying capacity adjustable range is 5.5～16.5m
3/ h.The enclosed construction that hopper 3 takes the shape of the letter U (Fig. 2) adopts quality carbon steel compression moulding, and smooth surface is smooth.Hopper 3 horizontal (horizontal type) is provided with, by support 2 support fixation.End near motor of hopper 3 is a feed end, and the other end is a discharge end.Feed end offers charging aperture and access hole 10, and discharge end offers discharging opening 5 and access hole 6, and access hole is convenient to be observed motor and feed status, also helps convenient maintenance.Device has temperature sensor 9 and fire extinguisher 8 on the hopper 3; When flue gas or flame strile-backd to batcher, temperature sensor 9 detected abnormal temperature, after the self water feeding valve is received response signal; Spray through 8 pairs of flames that strile-back of fire extinguisher, guarantee the safety of whole feeding system.The bottom of hopper 3 is equipped with one deck liner plate 4, adopts wear-resistant rubber sheet, has wear-resisting crushing resistance, and anti-flaming function is arranged.Helical blade 7 is no pivot structure, and thickness reaches 20mm, and spacing is 360mm, adopts integrated steel, one-shot forming.Helical blade 7 is built in the bottom of hopper 3, and motor 1 directly drives helical blade 7 and rotates.
As shown in Figure 2, the helical blade that does not have the axle screw(-type) feeder can be designed to the double helix blade, and conveying capacity can enlarged proximal one times like this, is equivalent to the conveying capacity that the common screw(-type) feeder of two platform independent is worked simultaneously.
