Description

Technical Field

[0001] This utility model relates to the field of production equipment, specifically a pneumatic conveying system for a color sorter. Background Technology

[0002] Color sorters, as highly precise devices, rely on subtle differences in the optical properties of materials to accurately identify and automatically separate discolored particles from granular materials using advanced photoelectric detection technology. In coffee production, color sorters are particularly crucial, focusing on the selection stage of coffee beans to ensure the purity and quality of each bean. During harvesting, processing, and storage, coffee beans are easily contaminated with various discolored impurities, such as dead beans, black beans, incompletely hulled beans, and beans with abnormal colors. The presence of these impurities severely affects the final flavor and taste of the coffee. Color sorters effectively solve this problem, not only precisely removing these impurities but also ensuring the consistency and purity of the coffee beans, laying a solid foundation for subsequent roasting and processing.

[0003] However, in the actual coffee production process, color sorters are usually used in conjunction with hopper conveyor systems. Hopper conveyor systems are widely favored due to their simple structure and convenient operation. But with the expansion of production scale and the increase in efficiency requirements, traditional hopper conveyor methods have gradually revealed many shortcomings. For example, hoppers are prone to blockage during the conveying process, leading to poor material flow and affecting the continuous operation of the color sorter; at the same time, the corners inside the hoppers are difficult to clean thoroughly, and the residue accumulated over time may contaminate the next batch of coffee beans, posing a potential threat to coffee quality; in addition, when dealing with large quantities of material, the conveying efficiency and flexibility of hopper conveyors are insufficient to meet the high-efficiency requirements of modern coffee production. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects and propose a solution to the problems existing in the traditional hopper material conveying method, aiming to reduce the failure rate, facilitate internal cleaning of the equipment, and improve the operating efficiency of material color sorting.

[0005] To achieve the above objectives, this utility model is implemented as follows:

[0006] A pneumatic conveying system for a color sorter includes a self-filtering cyclone material settling device, which specifically includes:

[0007] An inlet for receiving material from the front-end equipment of the color sorter;

[0008] An outlet for discharging the finished material after color sorting;

[0009] An outlet for discharging defective products or impurities;

[0010] The self-filtering cyclone material settling device is configured within the system to process materials conveyed by pneumatic conveying, thereby achieving material settling and filtration.

[0011] A pneumatic conveying pump is used to provide air to the system and drive the pneumatic conveying of materials within the system.

[0012] Furthermore, the self-filtering cyclone material settling device also includes:

[0013] A cyclone separator for efficient separation and settling of materials;

[0014] A filtration system, integrated after a cyclone separator, is used to filter out small particles and impurities in the air.

[0015] The above-mentioned filtration system specifically consists of:

[0016] A pre-filter, placed at the front end of the filtration system, is used to intercept large particulate impurities;

[0017] A high-efficiency filter follows, used to further intercept fine particles and ensure air quality.

[0018] The pneumatic conveying system for the color sorter described above uses a high-pressure air pump that provides stable and sufficient air pressure to ensure the effective conveying of materials within the system.

[0019] The aforementioned pneumatic conveying system for color sorters also includes a control system for precisely adjusting and controlling the operating parameters of the pneumatic conveying pump and the cyclone separator, thereby achieving automated control of the system.

[0020] Furthermore, the control system specifically includes:

[0021] A sensor for real-time monitoring of material flow status and airflow parameters;

[0022] A processor automatically adjusts the system's operating parameters based on data fed back from the sensors;

[0023] A user interface that allows operators to manually input commands and monitor the system's operational status.

[0024] The aforementioned pneumatic conveying system for a color sorter further includes:

[0025] Pneumatic conveying pipelines serve as material conveying channels, connecting the color sorter pre-stage equipment and the inlet of the self-filtering cyclone material settling device, as well as the finished material outlet of the self-filtering cyclone material settling device and subsequent storage or processing devices.

[0026] The pneumatic conveying pump is installed on the pneumatic conveying pipeline to provide power for the pneumatic conveying of materials.

[0027] The pneumatic conveying system for the color sorter described above is further equipped with a material recovery device connected to the non-conforming product outlet of the self-filtering cyclone material settling device, which is used to collect and process non-conforming products or impurities separated by the system.

[0028] Furthermore, the front-end equipment of the color sorter is the original stainless steel storage silo, and the finished materials processed by the system are also returned to the stainless steel storage silo for storage, realizing the recycling of materials.

[0029] The pneumatic conveying system for the color sorter described above is equipped with a flow control valve on the pneumatic conveying pipeline, which is used to adjust the conveying speed of the material according to actual needs, so as to realize flexible control of the system.

[0030] The pneumatic conveying system for color sorters proposed in this invention not only overcomes the inherent drawbacks of traditional hopper conveyors but also significantly improves the smoothness and efficiency of material conveying. By employing pneumatic conveying technology, materials are transported in a closed pipeline using airflow as the driving force, effectively avoiding blockages and contamination. Furthermore, the pneumatic conveying system offers greater flexibility and scalability, easily adapting to changes in scale and production needs. Moreover, the seamless integration of this system with the color sorter achieves a fully automated process from material conveying to screening, greatly improving the overall efficiency and quality control level of coffee production.
