Abstract

The invention discloses a front-end automatic feeding and sieving and de-ironing device in a rice husk three-state decomposition process. The front-end automatic feeding and sieving and de-ironing device comprises an outer conveying mechanism, a sieving and de-ironing mechanism and a discharging propelling mechanism which are connected in sequence, wherein the outer conveying mechanism comprises a containing bucket, a conveying pipe, a conveyor belt arranged in the feeding conveying pipe and a feeding elbow pipe; the sieving and de-ironing mechanism comprises a hopper arranged under the feeding elbow pipe and the conveying pipe is arranged under the hopper; the conveying pipe is provided with a vibration cover; the vibration cover is internally connected with a first vibration device and a second vibration device in sequence from top to bottom; and the discharging propelling mechanism comprises a transverse material conveying pipe, a transverse driving device, a transverse transmission blade, a discharging hopper, an observation opening and a transverse transmission rod. The invention aims at providing the front-end automatic feeding and sieving and de-ironing device in the rice husk three-state decomposition process; the conversion of rice husk three-state reaction is convenient, the production efficiency is improved, the impurity interferences are avoided and the safety accidents are avoided; and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to a feeding device of a rice husk pyrolysis system, in particular to a front-end automatic feeding and screening and iron removal device in the three-state decomposition process of rice husk. Background technique [0002] At present, all countries in the world, especially developed countries, are devoting themselves to the development of high-efficiency and non-polluting biomass energy utilization technologies in order to protect mineral resources, ensure national energy security, achieve carbon dioxide emission reduction, and protect the sustainable development of the national economy. . Biomass energy has become an important part of future sustainable energy. It is estimated that by 2016, 40% of the total energy consumption of global renewable energy will come from biomass energy, mainly through the industrial development of biomass power generation. [0003] Rice husk gas-fired power generation is a biomass energy developmen...

Problems solved by technology

[0005] The previous practice was that rice husks were manually poured into the feed hopper before entering the system for reaction, which was time-consuming, laborious, inefficient, and polluted by dust; in addition, due to the problems of storage and off-site transfer in rice husks , and the storage of rice husks is relatively random. There may be iron wires and iron filings brought in by production tools. If they are brought into the reaction device, it will have a certain damage to the reactor and interfere with the occurrence of rice husk decomposition reactions. , It is also easy to cause the problem of equipment blockage; in actual production, because we did not consider the problem of iron wire and iron filings in our early equipment, some equipment was damaged; it was only found that the problem was iron wire and iron filings during maintenance
