Description

Multichannel blanking device and grinding system using same Technical Field The utility model relates to the technical field of feeding devices, in particular to a multichannel blanking device and a grinding system using the same. Background In the grinding system, when the blanking slide, the V-shaped powder selecting machine and the roller press work cooperatively, the material is conveyed to the V-shaped powder selecting machine through the blanking slide, the high-efficiency separation of fine powder and coarse particles is realized through the scattering function of the V-shaped powder selecting machine and the separation airflow, the qualified fine powder is directly collected, and the coarse powder enters the roller press for secondary extrusion strengthening. In order to solve the problems of material congestion in the blanking chute and uneven distribution when the material enters the V-shaped powder concentrator, a distributing structure is designed in the blanking chute in the prior art, for example, a cement mill hoist blanking chute with uniform distribution and patent publication No. CN219647631U is arranged, the blanking chute is formed by sequentially connecting rectangular pipelines with multiple sections of different angles, and the material is dispersed step by step and prevented from being congested and forming a uniform material curtain through passages arranged in the upper pipeline and the lower pipeline in a grading manner and independent regulating plates (driven by a rotating motor) of eight blanking passages at the tail end, so that the phenomenon that fine powder is circulated back to a roller press along with coarse powder is reduced. However, in practical application, the design is found that due to complex structures such as a multi-section reducing channel, eight groups of motor-driven regulating plates and the like, the manufacturing process difficulty is high, the maintenance cost is obviously increased, the blanking slide is usually positioned in a high-altitude/narrow area, and multiple electromechanical elements are prone to failure in long-term operation, so that the practical economy and reliability are restricted.
