Description

Technical Field

[0001] This utility model relates to the technical field of slag discharge devices, and in particular to a slag discharge device for crushed rice. Background Technology

[0002] A rice crushing waste discharge device is used to handle crushed waste generated during rice processing. When rice is milled, the screening and hulling processes produce a large amount of byproducts. These byproducts need to be collected and further processed to achieve rational resource utilization and a clean production environment. The discharge device is responsible for effectively removing these crushed materials from the processing area, and its performance directly affects the efficiency and quality of rice processing.

[0003] A search revealed Chinese Patent Publication No. CN215507821U, which discloses a multi-stage impurity cleaning device for rice production. The device includes a support frame, a feeding hopper, and a primary cleaning chamber. The feeding hopper is located at the upper left end of the support frame, and its bottom is connected to the primary cleaning chamber inside the support frame. A discharge port is located on the left side of the primary cleaning chamber, and a blower is embedded on the right side. A discharge port is connected to the bottom of the primary cleaning chamber, and a conveyor belt is located directly below the discharge port. An active conveying roller is connected to the left end of the conveyor belt. This utility model, by setting up a filter screen, a vacuum cleaner, a multi-stage cleaning chamber, a first filter screen, a second filter screen, and a third filter screen, utilizes the synergistic effect of these components to achieve multi-stage filtration and cleaning of impurities in rice, greatly improving the cleaning effect and achieving a high degree of automation, thus reducing the workload of workers. However, the above structure does not take into account the oily nature of rice husks, which can cause bridging of crushed material at the bottom of the conical hopper, leading to discharge blockage, resulting in low work efficiency, poor performance, inconvenient disassembly and assembly, difficult maintenance, and short service life, making it difficult to meet usage requirements. Utility Model Content
