    摘要:

    通過對(duì)洞道混合式干燥機(jī)氣流狀態(tài)的測(cè)試分析,，對(duì)該機(jī)型的結(jié)構(gòu)進(jìn)行了改進(jìn)設(shè)計(jì)。提出了將風(fēng)機(jī)位置下移,、增加風(fēng)機(jī)數(shù)量,、中部排氣減壓等設(shè)計(jì)方案,。實(shí)踐表明,，改進(jìn)設(shè)計(jì)加強(qiáng)了干燥機(jī)氣流分布的均勻性，加快了干燥速度,，簡(jiǎn)化了設(shè)備結(jié)構(gòu),，強(qiáng)化了生產(chǎn)的連續(xù)性,，熱效率由原來的

    Abstract:

    45%提高到63%。 The air flow state of the commonly used mixed flow tunnel drier (MFTD) was measured and studied in this paper. Based on the test results, the structure improvement of the MFTD was carried out, which includes lowering the position of the blower, adding more blowers, and exhausting air in the middle of the tunnel. Test results of the improved MFTD indicated that the air flow is more uniformly distributed, the drying speed is enhanced, system structure is simplified, continuity of production is intensified, and the heat efficiency is increased from the original 45% to the current 63%.
