This application relates to the technical field of potato processing equipment, and more specifically, to a potato impurity removal and pulping device. In the potato impurity removal and pulping device provided in this application embodiment, a vertical rotating shaft drives a fan-shaped spreading plate to evenly spread the pulp into a thin layer on the upper surface of a circular screen plate. Combined with the directional cleaning function of a synchronously rotating brush, impurities can move synchronously circumferentially with the brush, preventing them from accumulating on the circular screen plate and clogging the screen holes. Using the above structural design, by integrating a rotating impurity removal mechanism below the crushing chamber, continuous crushing and impurity removal operations are achieved. Furthermore, the crushing and impurity removal operations can be carried out continuously without interruption, and there is no need to stop the machine to clean the circular screen plate during this process, thereby greatly improving the potato pulping efficiency.

A household kitchen waste short process high value system comprises a impurity removal pretreatment system, a wet anaerobic fermentation tank and an impurity removal dehydration deep treatment system, characterized in that the impurity removal pretreatment system is composed of a first-stage impurity removal screening machine and a first-stage impurity removal dehydration machine, the first-stage impurity removal dehydration machine is connected with the wet anaerobic fermentation tank, the wet anaerobic fermentation tank is connected with the impurity removal dehydration deep treatment system, and the impurity removal dehydration deep treatment system is composed of a second-stage impurity removal screening machine, a mixer and a second-stage impurity removal dehydration machine connected in sequence. The system solves the defects of traditional processing system such as complex process, low resource utilization rate, high investment and operation cost, etc. by optimizing equipment function, simplifying section equipment, reducing investment and operation cost and reducing energy consumption, which not only improves the operation stability of the anaerobic section, but also improves the quality of the final product.

The utility model provides a grading screening machine for low-carbon ferrochrome products, which belongs to the technical field of low-carbon ferrochrome production and comprises a material storage component, a support, a frame fixedly mounted in the middle of the support and a material collecting box mounted in the middle of the frame. The screening assembly comprises a supporting piece fixedly installed at the upper end of the frame body, a connecting piece connected to the upper end of the supporting piece in a threaded mode, a screening box rotationally installed on the side wall of the connecting piece, a screening plate fixedly connected to the inner side of the screening box and a feeding frame connected to the middle position of the end of the screening box in an inserted mode. The low-carbon ferro-chrome screening device has the advantages that the storage assembly and the screening assembly are used in cooperation, so that materials on the screening plate move sufficiently, the problems of material accumulation and screening hole blocking are avoided, the screening efficiency is improved, low-carbon ferro-chrome products with different particle sizes can be rapidly and accurately separated, the screening box can be conveniently adjusted and maintained, and the screening efficiency is improved. And the continuity and the stability of the whole screening process are ensured.
