Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and in particular, to an intelligent sorting and pretreatment integrated system for vegetable waste. Background Art

[0002] With the booming development of the vegetable industry, the quantity of waste such as the residual plants and rotten leaves generated during the vegetable planting process, as well as the leftover waste in the vegetable processing link, is increasing sharply. If these vegetable wastes are not properly treated, it will not only cause waste of resources, but also have a serious negative impact on the surrounding environment, such as emitting stench, breeding mosquitoes, and polluting the soil and water sources. Therefore, it is particularly important to conduct effective sorting and pretreatment of vegetable waste to lay a foundation for subsequent resource utilization or harmless treatment.

[0003] However, there are many deficiencies in the existing vegetable waste treatment technologies and systems:

[0004] The existing vegetable waste treatment is usually that each treatment link is independent. The feeding, sorting, and crushing operations are carried out in different equipment and sites respectively. This leads to frequent transfer of vegetable waste during the treatment process, which not only increases the labor and material costs, but also easily causes material loss. Moreover, the scattered treatment links are difficult to form a continuous and efficient treatment process, and the connection between each link is not smooth enough, which easily leads to treatment delays and the overall treatment efficiency is low. In contrast, the intelligent sorting and pretreatment integrated system for vegetable waste of the present invention integrates multiple treatment links into one, realizing one-stop treatment, greatly improving the treatment efficiency, and reducing material loss and treatment delays.

[0005] Most current vegetable waste treatment systems rely on a large amount of manual operations, which is particularly obvious in the sorting link. Manual sorting not only has a large labor intensity and low efficiency, but is also easily affected by human factors, resulting in low sorting accuracy and prone to misclassification and missed classification. At the same time, the existing systems lack advanced intelligent recognition and control technologies and are difficult to perform real-time and accurate treatment according to the actual composition and characteristics of vegetable waste. The present invention realizes highly automated and intelligent operation through the combination of an image recognition unit and an intelligent sorting unit, as well as an advanced control system, reduces manual intervention, and improves sorting accuracy and treatment efficiency.

[0006] Existing coarse separation equipment often has a single function and shows unsatisfactory separation effects for large-sized impurities and ferromagnetic metal impurities in vegetable waste. The design of some vibrating screen units is unreasonable, with fixed screen apertures that are difficult to adjust according to different types and humidities of vegetable waste, resulting in ineffective separation of large-sized impurities. These impurities may enter subsequent processing equipment, causing equipment blockage or damage. In addition, some processing systems do not have effective magnetic separation units, unable to remove ferromagnetic metal impurities in vegetable waste. These metal impurities will cause wear to subsequent equipment and may even pollute the environment during subsequent processing. The coarse separation unit of the present invention can effectively separate large-sized impurities and remove ferromagnetic metal impurities through a vibrating screen unit with adjustable vibration frequency and an efficient magnetic separation unit, extending the service life of subsequent equipment and improving the safety and environmental protection of processing.

[0007] Existing identification technologies have significant limitations in terms of accuracy and speed when identifying different components in vegetable waste. Traditional optical identification equipment is difficult to accurately distinguish plastics, stones, and different types of vegetable components, and has a slow processing speed, unable to meet the requirements of large-scale vegetable waste treatment. In the sorting process, due to the lack of accurate identification information and effective control means, sorting equipment can often only perform simple classification and cannot achieve precise separation of different components, resulting in low purity of the sorted materials and affecting the subsequent resource utilization effect. The image recognition unit of the present invention can quickly and accurately identify multiple components, and the intelligent sorting unit conducts efficient and precise sorting based on the recognition results and can flexibly adjust the sorting strategy, greatly improving the sorting accuracy and purity.

[0008] Existing crushing equipment usually can only provide a fixed crushing particle size and is difficult to adjust the crushing particle size of vegetable waste according to different subsequent processing requirements. This leads to the situation that the crushed materials may not meet the best conditions for subsequent composting and fermentation processes, affecting the efficiency of resource recovery and utilization. Moreover, the crushing effect of some crushing equipment is unstable, and uneven crushing easily occurs. The crushing unit of the present invention can control the crushing particle size of vegetable waste by adjusting the rotation speed of the crushing tool and the structural parameters of the crushing chamber, ensuring a uniform crushing effect and meeting the requirements of different subsequent processing technologies, thereby improving the efficiency of resource recovery and utilization.

[0009] Existing conveying equipment often has the problem of discontinuous conveying during the treatment of vegetable waste, which easily leads to material accumulation or stagnation, affecting the smoothness of the entire treatment process. In addition, the layout of traditional conveying equipment is relatively fixed and difficult to be flexibly adjusted according to different site conditions and treatment scales, restricting the applicability of the treatment system. The conveying unit of the present invention ensures continuous conveying of materials through the cooperation of multiple conveying units and elevators, and can be flexibly arranged according to the actual layout and site conditions to adapt to treatment projects with different scales and site requirements.

[0010] In the existing vegetable waste treatment system, the control between each unit is relatively independent, lacking centralized and unified management and coordination. Operators need to monitor and operate each device separately, which not only has a large workload but also is difficult to ensure the collaborative working effect between each unit. At the same time, the existing system lacks real-time monitoring and automatic adjustment functions. When the operating parameters of a certain device change, it cannot be adjusted in time, easily resulting in unstable treatment effects. The control system of the present invention uses a programmable logic controller (PLC) to centrally control and coordinate each unit, and automatically adjusts parameters by real-time monitoring the operating state through sensors, ensuring the stable operation of the system and the consistency of treatment effects. Therefore, we make improvements and propose an intelligent sorting and pre-treatment integrated system for vegetable waste. Summary of the Invention

[0082] Example 2: Intelligent Sorting and Pretreatment Integrated System for Vegetable Waste: A large vegetable processing enterprise generates a large amount of vegetable waste every day, which is mixed with branches, plastics, and ferromagnetic metal impurities. The enterprise hopes to introduce an intelligent sorting and pretreatment integrated system to achieve efficient sorting and preliminary treatment of vegetable waste and prepare for subsequent resource utilization or harmless treatment.

[0083] The conveying unit uses a belt conveyor with a length of 5 meters, a width of 1 meter, and a conveying speed that can be adjusted between 0.5 - 2 m / s.

[0084] The feeding unit is a vibrating feeder installed at the starting end of the belt conveyor. Vegetable waste is poured into the hopper of the vibrating feeder by a forklift or other transportation tools. The vibrating feeder evenly drops the vegetable waste onto the belt conveyor and then conveys it to the subsequent processing units.

[0085] Vibrating screen unit: The inclination angle is 20°, and the screen aperture is set to 50 mm. The vibration frequency of the vibrating screen unit can be adjusted between 10 - 30 Hz to adapt to different types and humidities of vegetable waste. The vegetable waste is vibrated and screened on the vibrating screen unit. Large - sized impurities such as branches and plastics remain on the screen and slide into the collection trough through the inclination angle.

[0086] Magnetic adsorption unit: An electromagnetic separator is used and installed above the vibrating screen unit. When the vegetable waste passes by, the electromagnetic separator adsorbs the ferromagnetic metal impurities in it, and the electromagnetic separator is periodically turned off to collect the adsorbed metal impurities.

[0087] High - speed camera: Installed above the belt conveyor, it can take 100 images per second to ensure clear capture of the images of vegetable waste.

[0088] Image processing system: A high-performance computer equipped with deep learning algorithms is used to analyze and process the collected images. It can identify different components in vegetable waste, such as rotten vegetables, utilizable vegetables, and impurities, and mark their positions and characteristics.

[0089] Jet nozzles: Twenty jet nozzles are evenly distributed along the width direction above the belt conveyor. The pressure of the high-pressure gas ejected by the jet nozzles can be adjusted between 0.2 - 0.8 MPa. According to the information provided by the image processing system, the jet nozzles at the corresponding positions are controlled to eject high-pressure gas to blow the identified impurities or vegetable waste of specific components off the belt conveyor and into the corresponding collection containers.

[0090] Control unit: It is connected to the image processing system and the jet nozzles, receives the information from the image processing system, and controls the actions of the jet nozzles.

[0091] Crushing chamber: Made of stainless steel with a volume of 1 cubic meter.

[0092] Crushing knives: Installed in the crushing chamber, driven by a motor, and the rotation speed can be adjusted between 1000 - 3000 revolutions per minute. Vegetable waste enters the crushing chamber through the belt conveyor, and the crushing knives crush it into fine particles.

[0093] Multiple belt conveyors and elevators connect the various processing units. For example, the belt conveyor of the feeding unit transports vegetable waste to the rough sorting unit, and the materials processed by the rough sorting unit are transported to the belt conveyor where the image recognition unit is located through the elevator, and so on, ensuring that the vegetable waste can be smoothly transported from one processing unit to the next.

[0094] A programmable logic controller (PLC) is used to monitor the operating status of each unit in real time through sensors, such as the speed of the belt conveyor, the vibration frequency of the vibrating screen unit, and the current of the motor. The operating parameters of the system are automatically adjusted according to the preset program. When a fault is detected in a certain unit, the system will automatically alarm and stop running.

[0095] Through the implementation of this system, the vegetable processing enterprise has achieved efficient sorting and preliminary treatment of vegetable waste. The rough sorting unit effectively separates large-sized impurities and ferromagnetic metal impurities. The image recognition unit and the intelligent sorting unit can accurately identify and sort different components of vegetable waste. The crushing unit crushes the sorted vegetable waste into fine particles, providing good conditions for subsequent resource utilization or harmless treatment. At the same time, the high degree of automation and intelligence of the system reduces manual intervention, improves the processing efficiency, and reduces the processing cost.
