Because non-renewable fossil fuel is develop and useedd in a large number, has brought serious energy crisis and environmental crisis, brought serious problems for sustainable development of social economy and existent environment of people.Nowadays, the development and utilization of regenerative resource has become the emphasis of various countries' research and development, and biomass resource is the unique resource that can store and transport in the regenerative resource, becomes the focus of researching and developing in the regenerative resource.Biomass molding fuel easy realization of large-scale production and use use the comfort level of biomass molding fuel particle to compare favourably with combustion gas, fuel oil equal energy source.So exploitation biomass molding fuel particle device has favorable economic benefit and social benefit.
China is devoted to the biomass molding fuel Study on Technology since the eighties, mainly introduces complete set of equipments such as Korea S, Taiwan, Japan, and based on screw extruder.Subsequently, state's technical equipment such as Holland, Belgium also push China in succession." the Seventh Five-Year Plan " beginning, some domestic scientific research institutions and enterprise begin biomass molding fuel theory and equipment are studied, before and after nineteen ninety, some units successively develop and have produced the biomass moulding unit of several different sizes, and these equipment comprise mechanical stamping formula make-up machine, hydraulic drive piston formula make-up machine, electrical heating screw rod make-up machine etc.Enter 21 century, the fossil energy price is soaring continuously, and environmental pollution increasingly sharpens, and country begins various renewable and clean energy resource exploitations are paid attention to, biomass molding fuel has also entered good developing stage, and graininess, blockage shape shaped fuel also cause shows great attention to.At present, comprise that domestic a lot of enterprise and universities and colleges, scientific research institutions have developed squash type, hydraulic shock formula, screw shaped fuel production equipment, and be extensive use of at aspects such as biomass power generation, warming stove, boiler, charcoal productions.
At present, the major defect of biomass molding fuel particle device existence is:
(1) the consumable accessory life-span of biomass molding fuel equipment shorter, stabilization of equipment performance is poor.Biomass moulding equipment majority is by the production of fodder equipment improvement, and biomass material is to the critical component quick abrasion, and working life is short, and the equipment fluctuation of service influences large-scale production;
(2) the biomass molding fuel equipment adaptability to raw material is poor, and service ability is low continuously.Supply of raw material is subjected to cost in season, transportation radius etc. to influence the kind variation greatly, because equipment can not adapt to the diversity of raw material type, cause the equipment have to discontinuous operation, there are the most times to be in idle state in 1 year, cause the wasting of resources, the equipment natural wastage is serious, has increased the equipment payback period.If will satisfy equipment produces continuously, will increase reserve storage, this method all can cause investment to increase, and the best way is that equipment has adaptability to raw material widely, so just can reduce extra investment to greatest extent.
See also shown in Figure 1, include pressure roller main body 13 in the pressure roller of prior biological matter molding fuel equipment, this pressure roller main body 13 comprises the pressure roller shaft 17 that is arranged on pressure roller main body 13 transversal lines, be symmetricly set on two mouthfuls of taper roll bearings 15 in the pressure roller main body 13 around pressure roller shaft 17, pressure roller main body 13 is assemblied on the pressure roller shaft 17 by two mouthfuls of taper roll bearings 15, two mouthfuls of taper roll bearings 15 adopt 32218 models mostly, equipment sound load has two mouthfuls of taper roll bearings 15 to bear fully, biomass material dynamic loading in the compression forming process is bigger, make have only about 80～100h the service life of two mouthfuls of taper roll bearings 15, seriously restricted the normal operation of equipment.
Summary of the invention
The purpose of this utility model is to overcome the roller structure weak point in service life of prior art, the problem of the normal operation of restriction biomass molding fuel equipment, a kind of raising bearing service life, the roller structure that makes biomass molding fuel equipment rate operation normally and efficiently are provided.
For realizing above purpose, the utility model has been taked following technical scheme: a kind of roller structure of biomass molding fuel equipment, include the pressure roller main body, be arranged in the pressure roller shaft on the described pressure roller main body transversal line, being symmetrically arranged with at least two mouthfuls of taper roll bearings with pressure roller shaft in the both sides up and down of described pressure roller shaft, pressure roller main body, is that symmetry axis is respectively arranged with a bite cylinder roller bearing at least between two mouthfuls of taper roll bearings of described pressure roller shaft both sides, with the pressure roller shaft.
Described cylinder roller bearing two ends are connected with adjacent taper roll bearing respectively.
The utility model compared with prior art, have following advantage: the utility model is by improving roller structure, on the one hand the sound load that bearing itself can load is bigger, equipment sound load is born by taper roll bearing and cylinder roller bearing on the other hand, so just improved the service life of bearing greatly, can reach 200～300h, 80～100h in service life is significantly increased than the prior art bearing.
