Embodiment explanation: the novel vertical ring mould stalk block making machine that adopts heater and heat sink to combine
In November, 2011 is Ministry of Agriculture's biomass molding fuel demonstration base in Daxing, Beijing, adopts maize straw to carry out the moulding fuel production.Shaping raw material adopts maize straw, and granularity is at 10mm～15mm, and moisture content is 20%; When beginning to produce, ring mould and temperature of charge all do not reach forming temperature, difficult forming; Resistive heater can be given the preheating of ring mould up and down, makes ring mould and material all reach the moulding preference temperature as early as possible.Under the situation that does not adopt resistive heater, reach the moulding preference temperature, need about 20 minutes, and after having adopted the resistive heater preheating, reaching the moulding preference temperature only needs about 2 minutes.Production was carried out a period of time of after, because the friction of material and ring mould causes the ring mould overheated, the molding effect that causes extruding product is bad; Loose, even do not become piece, shut down cooling until needs; The shaped fuel temperature of producing simultaneously is higher, should expand after extruding, and ratio of briquetting is low; Result of the test shows that ratio of briquetting is merely 75%～85%, does not reach standard-required; Open the cooling water channel, utilize cooling water will encircle the mould temperature and take away, ring mould temperature is lowered as early as possible; And maintain about 80 ℃, ratio of briquetting improves, the also corresponding raising of productivity ratio; Result of the test shows that ratio of briquetting reaches more than 95%, and this has not only prolonged the ring mould life-span, and has improved Forming Quality; Avoided shutting down cooling, thereby improved productivity ratio.The novel vertical ring mould stalk block making machine that adopts heater and heat sink to combine can improve productivity ratio about 10% on the whole.
What should explain is; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
