Description
技术领域Technical Field
本实用新型涉及筛分装置技术领域，具体为一种棉仁预处理用筛分装置。The utility model relates to the technical field of screening devices, in particular to a screening device for pre-processing cotton kernels.
背景技术Background technique
棉籽经剥壳后得到含有仁壳的混合物，生产过程中必须将这些混合物中的棉仁与棉壳分离开来，分离出的棉仁用于后续浸出油脂，棉壳直接包装，若仁壳分离不清，棉仁中带的壳过多，将会影响出油率和蛋白含量，有效地分离棉仁与棉壳，才能实现对后续制油浸出工艺更好的控制，提升成品油质量，增加成品油产量，因此，采用较好的仁壳分离设备和工艺，才能够使剥壳后棉仁和棉壳达到较为彻底地分离，实现对工艺与产品质量的更好控制。After shelling, cotton seeds are obtained to obtain a mixture containing kernels and husks. In the production process, the cotton seeds and husks in the mixture must be separated. The separated cotton seeds are used for subsequent oil extraction, and the cotton husks are directly packaged. If the kernels and husks are not separated clearly, there will be too many husks in the cotton seeds, which will affect the oil yield and protein content. Only by effectively separating the cotton seeds and husks can better control the subsequent oil extraction process, improve the quality of finished oil, and increase the output of finished oil. Therefore, the use of better kernel and husk separation equipment and technology can achieve a more thorough separation of the cotton seeds and husks after shelling, and achieve better control of the process and product quality.
传统工艺筛分过程中外排棉壳含仁(仁比壳贵)、产量大时震动风选筛负荷高，仁壳分离效果差，物料内部的杂质不能充分筛除，影响后续浸出工艺，产品得率偏低，例如中国实用新型公开说明书为CN217393004U专利，公开了一种棉仁预处理用筛分装置，包括壳体，壳体的顶部安装有绞龙筛机构，绞龙筛机构包括固定在壳体上的筛筒，筛筒两端安装有U型座，U型座之间设有绞龙轴，绞龙轴的两端通过轴承固定在U型座上，绞龙轴的侧面安装有绞龙叶片，且绞龙轴的一端连接有电机，电机通过电机支架固定在U型座上，壳体的底部开设有出料槽，壳体的底部四角均安装有支架，支架之间安装有安装板，安装板上依次设有第一筛板、第二筛板和第三筛板，且第一筛板、第二筛板和第三筛板的孔径依次减小。本申请通过绞龙筛机构可对物料进行初步筛分，再经过第一筛板、第二筛板和第三筛板对物料进行二次筛分，筛分充分，提高筛分效果。In the screening process of the traditional process, the outer cotton husk contains kernels (kernels are more expensive than husks), the load of the vibrating air separation screen is high when the output is large, the kernel-shell separation effect is poor, the impurities inside the material cannot be fully screened out, affecting the subsequent leaching process, and the product yield is low. For example, the Chinese utility model disclosure is CN217393004U patent, which discloses a screening device for cotton kernel pretreatment, including a shell, a screw screen mechanism is installed on the top of the shell, the screw screen mechanism includes a screen cylinder fixed on the shell, U-shaped seats are installed at both ends of the screen cylinder, an screw shaft is arranged between the U-shaped seats, both ends of the screw shaft are fixed to the U-shaped seats through bearings, screw blades are installed on the side of the screw shaft, and one end of the screw shaft is connected to a motor, the motor is fixed to the U-shaped seat through a motor bracket, a discharge trough is opened at the bottom of the shell, brackets are installed at the four corners of the bottom of the shell, a mounting plate is installed between the brackets, a first sieve plate, a second sieve plate and a third sieve plate are arranged on the mounting plate in sequence, and the apertures of the first sieve plate, the second sieve plate and the third sieve plate are reduced in sequence. The present application can perform preliminary screening of materials through the auger screen mechanism, and then perform secondary screening of the materials through the first sieve plate, the second sieve plate and the third sieve plate, so that the screening is sufficient and the screening effect is improved.
现有的棉仁预处理用筛分装置不具有较好的筛分的效果，例如上述专利虽然可以通过第一筛板、第二筛板和第三筛板对物料进行二次筛分，提高了筛分效果，但是在实际使用过程中只通过三层筛板无法将杂质充分筛除，仁壳分离效果较差，出仁率低，使得棉仁预处理用筛分装置筛分效率较低。The existing screening device for cotton kernel pretreatment does not have a good screening effect. For example, although the above patent can perform secondary screening on the material through the first sieve plate, the second sieve plate and the third sieve plate, thereby improving the screening effect, in actual use, impurities cannot be fully screened out by only three layers of sieve plates, the kernel-shell separation effect is poor, and the kernel yield is low, resulting in a low screening efficiency of the screening device for cotton kernel pretreatment.
