Abstract
The invention belongs to the field of biomass fuel boilers or gasifier feeder machine equipment and particularly relates to a loading plunger type screw feeder. A loading plunger good in sealing performance can be formed. The situation that due to high-temperature heating, the loading plunger is burnt and damaged can not occur, and stability and reliability are achieved. The screw feeder comprises a screw feeder body, and the tail end of the screw feeder body is connected with a boiler hearth. The screw feeder is characterized in that a spiral shaft of the screw feeder body penetrates through a bearing block and is connected with a coupler; the coupler is connected with a speed reduction motor; a loading plunger section is arranged in the position, at least one screw pitch away from the tail end, of the spiral shaft of the screw feeder body; the length of the loading plunger section equals to one to two screw pitches; the part, at the loading plunger section, of the spiral shaft is not provided with blades or the diameter of blades at the part is smaller than or equal to 50% of the diameter of other blades.
Description
Technical field
The invention belongs to biomass fuel boiler or gasification furnace feeder technical field of mechanical equipment, be specially a kind of material plug type screw feeder.
Background technology
Today of 21 century, along with developing rapidly of economy, the havoc of natural environment, energy problem is becoming tight day, and people have to find the new energy, new product.In order to the development in the epoch of complying with, biomass fuel is just widely used as fuel.Biomass fuel is generally utilize screw feeder to send into burner hearth, owing to having high temperature and pressure environment in stove, high-temperature flue gas easily lets out outside by feeder, so the screw feeder of routine connects one section, place at exit end and stove not do blade, form one section and expect that plug is blocked flue gas and leaked, as shown in Figure 1.Because the kind of biomass fuel is a lot, physical property difference is large, and this material plug is feasible for part of fuel, but some fuel is not all right.This is because some fuel very easily ignition, the material plug near burner hearth place is often easily burnt very soon, and between fuel, gap is comparatively large, thus can not form material plug, does not have sealing function.
Summary of the invention
In order to solve the problem, the invention provides a kind of material plug type screw feeder, it can form the material plug of good airproof performance, can not be subject to high-temperature heating and combustive destruction material plug, reliable and stable.
Its technical scheme is such: a kind of material plug type screw feeder, it comprises screw feeder, described screw feeder end connects boiler furnace, it is characterized in that, the screw shaft of described screw feeder connects coupler through bearing seat, described coupler connects reducing motor, screw shaft distance at least one pitch distance place of end of described screw feeder is provided with material plug section, described material plug segment length is one or two pitch, the screw shaft at described material plug section place does not arrange blade or blade diameter is less than or equal to 50% of rest blade diameter.
It is further characterized in that, described material plug segment length is two pitch;
The distance of screw shaft end two pitch described in described material plug segment distance;
After adopting structure of the present invention, material is carried by blade by screw shaft after entering screw feeder, screw shaft due to material plug section place when arriving material plug section does not arrange blade or blade diameter is less than or equal to 50% of rest blade diameter, material can not rely on blade to carry completely, but rely on blade below to promote material advance, material below promotes material above again, thus generation squeezing effect, finally form the material plug of one section of denser, block the space of housing, form the material plug of good airproof performance, material plug segment distance end has the distance of at least one pitch simultaneously, blade is had to isolate, directly can not be subject to high-temperature heating and combustive destruction material plug, reliable and stable.
Accompanying drawing explanation
Fig. 1 is structural representation in prior art;
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a kind of material plug type screw feeder, it comprises screw feeder 1, screw feeder 1 end connects boiler furnace 2, the screw shaft 3 of screw feeder 1 connects coupler 5 through bearing seat 4, bearing seat 4 is installed on base 6, coupler 5 connects reducing motor 7, transmitting torque, the screw shaft 3 of screw feeder 1 is provided with material plug section 8 apart from end two pitch distance places, material plug section 8 length is one or two pitch, the words material promotion difficulty that material plug section 8 is oversize, too short words cannot form the material plug of good airproof performance, the screw shaft 3 at material plug section 8 place does not arrange blade 9 or blade diameter is less than or equal to 50% of rest blade 9 diameter, do not arrange the blade that blade 9 is about to this place original to excise completely, blade diameter is less than or equal to 50% of rest blade 9 diameter and namely not exclusively excises blade, only cut a part, move towards along original blade screw, the blade of a pitch distance from depth of blade be 0 be smoothly transitted into that depth of blade is former depth of blade 50%, being smoothly transitted into depth of blade is again 0, because material plug section 8 is formed in centre, screw shaft 3 can make isometrical screw shaft, and processing and manufacturing is easy.
Claims (3)
1. a material plug type screw feeder, it comprises screw feeder, described screw feeder end connects boiler furnace, it is characterized in that, the screw shaft of described screw feeder connects coupler through bearing seat, described coupler connects reducing motor, screw shaft distance at least one pitch distance place of end of described screw feeder is provided with material plug section, described material plug segment length is one or two pitch, the screw shaft at described material plug section place does not arrange blade or blade diameter is less than or equal to 50% of rest blade diameter.
2. one material plug type screw feeder according to claim 1, it is characterized in that, described material plug segment length is two pitch.
