Description
Technical field
The invention belongs to green energy resource equipment manufacturing key technology area, more particularly to a kind of biomass combustion machine.
Background technology
In the case of today's society rapid economic development, resources conservation and environment-friendly double properties turn into various countries
The deciding factor of sustainable development.And with the development of the social economy, the mankind increasingly increase the demand of primary energy, coal,
The consumption of the fossil fuels such as oil exacerbates the pollution of environment.Therefore, a kind of reproducible alternative energy source is found, reduces greenhouse gas
The discharge of body, as countries in the world focus of attention.Biomass energy is a kind of renewable and clean energy resource, has volatility height,
Pollute the features such as small, and China has abundant biomass resource, for the fundamental realities of the country in China and biomass resource, research
Undoubtedly turn into China with Developing Biomass combustion technology and efficiently utilize one of effective way of biomass resource.China's biomass fuel
The research of burning technology and its combustion apparatus is at the early-stage, develops easy, environmental protection, efficient, energy-conservation biomass burner is current
The subject matter that scientific research personnel faces.
Traditional biomass burner is respectively provided with material push structure, and biological particles are sent into combustion chamber by the mechanism,
As shown in figure 1, common material transport mechanism is screw conveyer structure, inventor often gives birth in actual use
Material grainses fall into spiral the situation for blocking spiral, and then cause biomass burner cisco unity malfunction.Especially when
When the moisture of biological particles is higher, putty situation occurs more frequent.
The phenomenon of biological particles putty is also developed personnel and finds and improved or solved gradually, wherein inventor sieve
The existing mode for solving the problem of two kinds of row：
(1) increase drives the power of the transport mechanism of helical rotation.Typically increase the power of motor to improve spiral pair
The stirring dynamics and transfer rate of biological particles, and then alleviate the generation of putty phenomenon.
(2) by the way of double helix conveys feeding, Chinese invention patent 201220334205.X discloses this mode,
The burner carries out feeding using two conveying worms, makes fuel more uniform in burning indoor distribution, avoids fuel local
Accumulation is smouldered, and extends the service life of fire grate in combustion chamber；When biological particles blockage phenomenon in conveying worm,
The present invention is expected that helical blade reversely rotates and reversely pushes back biomass granule fuel and solved the problems, such as this side of putty by counter
Formula can solve the problems, such as putty to a certain degree.
Two ways above can solve the generation of biological particles putty phenomenon to a certain extent or can
Quickly solve the problem when putty phenomenon occurs, but each have shortcoming.Although first way can reduce stifled
Expect the generation of phenomenon, but bring the problem of new, i.e., its noise increases while the power of motor improves, and high energy consumption；Second
Kind of mode is complicated, and the invention sets up a conveying worm by superposition and has been used as standby conveying worm to improve device
Performance, and this kind of working method does not solve the problems, such as that putty easily occurs for biological particles directly, at the same time, two spiral shells
The probability that rotation conveyer breaks down can be higher than the probability that single conveying worm breaks down, so this working method may
Biological particles putty phenomenon can be made more serious.
The content of the invention
It is an object of the invention to provide a kind of biomass combustion machine, by the simple change of transfer structure, solves biology
