摘　　要：针对国内基质混合装置存在结构复杂、维护不便、产能低等问题,提出了一种旋转混合方式的基质在线混合装置。首先对提出的基质在线混合装置进行探究试验,确定基质在线混合装置结构。通过固定混合机构阻挡试验优化基质在线混合装置结构参数,在试验样机上进行了固定混合与转轮机构复式混合试验,测量基质成分均匀性。试验结果表明:在搅拌杆杆间距30mm、下落高度616mm、椰糠含水75%、泥炭含水率低、旋转混合轮转速20Hz、待混合原料厚度60mm时,混合后基质成分均匀程度达到现行基质生产企业采用基质生产方式的最优标准,基质在线混合装置的产能可达批量混合装置的4 5倍。该研究结果可为基质在线混合装置的设计开发提供参考。Because complex structure for the matrix mixing device in our country,maintenance inconvenience,low capacity and so on. In this paper,a matrix hybrid system for rotary mixing proposed. First,the substrate on-line mixing apparatus proposed in this study to explore and test,determine the matrix on-line mixing device structure. The stability of the substrate by means of a fixed mixing mechanism is used to optimize the structure parameters of the substrate. A mixed mixing test was carried out on the test prototype,measuring the uniformity of matrix composition. Experimental results table： in the pole arduous 30 mm,drop height of 616 mm,coconut moisture content 75%,peat moisture content is low,rotary mixing wheel speed 20 Hz,to be mixed with a raw material thickness of 60 mm. The uniformity of the matrix composition after mixing to achieve the current matrix production enterprises using matrix production standards of the best standards. The production capacity of the matrix in-line mixing device can be at least 4-5 times that of the horizontal mixing device. The results of this study can provide reference for the design and development of matrix in-line mixing device.
