Abstract

The utility model provides boiler spiral fire grate.Between mounting rail and gripper shoe, be provided with helix tube, helix tube is provided with the helical tooth of helical structure, and the spiral tubular axis of mounting rail side is equipped with travelling gear.Travelling gear and power set are in transmission connection.Helix tube is provided with passage.One group of two helix tube direction of rotation is contrary, and interval both forward and reverse directions rotates.It is abundant that the utility model has fuel combustion, and air permeability is good, and efficiency of combustion is high, and heat utilization rate is high, achieves the effect of energy-conserving and environment-protective.The suitable fire grate as biomass granular fuel boiler uses.

Description

Boiler spiral fire grate
Technical field
The utility model provides a kind of combustion apparatus of biomass fuel, specifically boiler spiral fire grate.
Background technology
Currently on boiler, often use traveling-grate stoker, the shortcoming that this fire grate exists is that air permeability is bad, the easy coking of fuel, and is not easy after coking to remove.
Summary of the invention
In order to overcome the shortcoming of boiler coke and air permeability difference, the utility model provides boiler spiral fire grate.This fire grate, by screw propulsion fuel combustion, solves the technical problem of boiler oil transmission and burning.
The scheme that the utility model technical solution problem adopts is:
Between mounting rail and gripper shoe, be provided with helix tube, helix tube is provided with the helical tooth of helical structure, and the spiral tubular axis of mounting rail side is equipped with travelling gear.Travelling gear and power set are in transmission connection.Helix tube is provided with passage.One group of two helix tube direction of rotation is contrary, and interval both forward and reverse directions rotates.
Good effect, it is abundant that the utility model has fuel combustion, and air permeability is good, and efficiency of combustion is high, and heat utilization rate is high, achieves the effect of energy-conserving and environment-protective.The suitable fire grate as biomass granular fuel boiler uses.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model spiral fire grate ordered state figure
In figure, 1. mounting rail, 2. gripper shoe, 3. helix tube, 3.1. helical tooth, 4. travelling gear.
Detailed description of the invention
According to the figure, be provided with helix tube 3 between mounting rail 1 and gripper shoe 2, helix tube is provided with the helical tooth 3.1 of helical structure, and the spiral tubular axis of mounting rail side is equipped with travelling gear 4.Travelling gear and power set are in transmission connection.
Helix tube is provided with passage.
One group of two helix tube direction of rotation is contrary, and interval both forward and reverse directions rotates.
The utility model uses:
Spiral fire grate is contained in lower portion thereof, and the fuel added, under the helical tooth of helix tube promotes, moves forward, stirs change of fuel direction simultaneously, form gap between helical tooth, be beneficial to ventilation.Passage also can play the effect of supplemental oxygen simultaneously, and make fuel combustion air feed sufficient, prevent anoxic and incomplete combustion, helical tooth also produces toggle action to fuel simultaneously, prevents fuel coking, obviously energy-conservation, favourable to environmental protection.
