Technical Field
[0001] This utility model relates to the field of sorting equipment technology, and in particular to a multi-stage sorting equipment for crushed and mixed household appliance materials. Background Technology
[0002] In the field of waste household appliance recycling, the mixture after primary crushing typically exhibits complex composition and diverse forms, containing various heterogeneous components such as metals, plastics, and insulation layers. Existing sorting processes generally employ a combination of multi-stage crushing, density sorting, magnetic separation, and sieving. While this achieves basic classification, it suffers from lengthy process chains and low equipment integration. Specifically, traditional equipment often incorporates numerous vibrating screens, magnetic separators, and airflow separation modules to improve sorting accuracy, leading to increased system footprint, higher energy costs, and significantly increased equipment failure rates and maintenance difficulties due to the complex mechanical structure. Furthermore, the over-configuration of sensor networks in the sorting process not only raises hardware costs but also affects the stability of sorting efficiency due to signal interference. The current technological bottleneck lies in how to achieve intensive equipment design through process innovation, simplifying the system architecture while maintaining sorting accuracy. This is of significant engineering importance for reducing lifecycle maintenance costs and improving the economics of resource recycling. Utility Model Content

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0031] like Figures 1 to 7 As shown, a multi-stage sorting device for crushed and mixed household appliance materials includes a vibrating feed assembly 1, which is connected to a Z-type separator 3. The Z-type separator 3 is connected to a first sorting cyclone 5, which is connected to a second sorting cyclone 6. The other end of the second sorting cyclone 6 is connected to the Z-type separator 3. The inlet of the Z-type separator 3 is connected to the vibrating feed assembly 1, and a blower 4 is integrated inside to achieve multi-stage airflow sorting. The sorting chamber is divided into three discharge zones according to the material density gradient: the top discharge port is connected to the first sorting cyclone 5 to discharge light materials, the middle discharge port is connected to the second sorting cyclone 6 through a first pipe 8 to discharge medium-density materials, and the bottom discharge port directly discharges heavy materials. Due to their large inertial centrifugal force, the heavy materials are thrown against the wall of the sorting cyclone hopper. In the first and second cyclone hoppers 5 and 6, when materials heavier than the airflow can lift are thrown onto the walls of the first and second cyclone hoppers 5 and 6, they will slowly fall down to the bottom of the hopper along the walls, and finally be turned out of the hopper by the rotation of the air shut-off valve.
[0032] Among them, the vibrating feed assembly 1 is responsible for the uniform input of materials. The Z-type separator 3 forms a directional airflow field through the built-in blower 4, and realizes airflow separation by utilizing the difference in material density. The separated materials are separated through the first separating cyclone 5 and the second separating cyclone 6 for multi-stage separation, and finally complete the precise classification of different material components. By replacing the traditional mechanical separation mechanism with airflow dynamics, the equipment structure is significantly simplified while ensuring the separation accuracy, reducing the manufacturing and maintenance costs of the equipment, effectively solving the problem of separating heterogeneous components in the crushed waste household appliances, and providing pretreatment guarantee for subsequent metal recycling and plastic sorting processes.
[0033] The vibrating feed assembly 1 includes a vibrating support 101, on which a vibrating screen 103 is mounted. A rubber spring 105 is installed between the vibrating support 101 and the vibrating screen 103. The vibrating screen 103 is connected to a vibrating motor 102. When the vibrating motor 102 vibrates, it can drive the entire vibrating screen 103 to vibrate. At the same time, the rubber spring 105 can reduce the pressure on the vibrating support 101. The installation of the rubber spring 105 can also make the vibration of the entire vibrating screen 103 more obvious.
[0034] The vibrating screen 103 is inclined on the vibrating support 101. The lower end of the vibrating screen 103 is connected to the first air valve 2. When the vibrating screen 103 vibrates, the material will gradually move along the inclined lower side, so that the material is gradually and evenly fed into the first air valve 2. A protective cover 105 is provided above the connection between the vibrating screen 103 and the first air valve 2. The protective cover 105 can prevent the material from jumping out of the vibrating screen 103 when it is vibrated, so that the material can always fall from the vibrating screen 103 into the first air valve 2.
[0035] The first air-closing valve 2 includes a first air-closing housing 201, inside which is a first fan blade 203. The first fan blade 203 is connected to a first motor 202. The contact area between the first fan blade 203 and the interior of the first air-closing housing 201 is made of rubber. Driven by the motor 202, the first fan blade 203 forms a dynamic airlock, which divides the first air-closing housing 201 into two non-communicating parts. This allows materials to be fed into the Z-type sorter 3 in batches, preventing too much material from being fed into the Z-type sorter 3 at once, thus affecting the airflow's conveying effect on the materials.
[0036] The Z-type separator 3 is equipped with a second air shut-off valve 301 at the lower end, the first material distribution cyclone 5 is equipped with a third air shut-off valve 501 at the lower end, and the second material distribution cyclone 6 is equipped with a fourth air shut-off valve 601 at the lower end; the second air shut-off valve 301, the third air shut-off valve 501 and the fourth air shut-off valve 601 have the same structure.
[0037] The second air shut-off valve 301 includes a second air shut-off housing 3012, inside which a second fan blade 3013 is provided. The second fan blade 3013 is connected to a second motor 3011. The contact area between the second fan blade 3013 and the interior of the second air shut-off housing 3012 is made of rubber, so that the contact area between the inner wall of the second air shut-off housing 3012 and the second fan blade 3013 is in a sealed state. Therefore, it is ensured that the sorting equipment can always maintain the air shut-off state and ensure the air pressure state inside the sorting equipment.
[0038] An air valve 7 is installed between the Z-type separator 3 and the first material cyclone hopper 5. The air valve 7 is used to adjust the air volume inside the equipment, thereby adjusting the sorting speed.
[0039] The air valve 7 includes a valve pipe 701, to which a valve plate 702 is inserted. By moving the valve plate 702, the opening size of the valve pipe 701 can be adjusted, thereby changing the amount of airflow entering the sorting equipment and thus changing the air volume inside the equipment.
[0040] Z-type separator 3 and second material cyclone 6 are connected by first pipe 8, which is a circular bend; first material cyclone 5 and second material cyclone 6 are connected by second pipe 9.
[0041] Vibrating feed assembly 1, Z-type separator 3, first material cyclone hopper 5, and second material cyclone hopper 6 are all mounted on the cage frame 10. The cage frame 10 is equipped with a platform 10B, and a guardrail 10C is installed around the platform 10B. A ladder 10A is installed on one side of the platform 10B, which allows operators to climb onto the platform 10B to observe the operation of the equipment.
[0042] This sorting equipment features an integrated blower system that replaces a complex transmission device, effectively reducing equipment complexity. The multi-stage cyclone sorting components enable automatic material stratification, minimizing manual intervention. Modular design significantly reduces maintenance costs compared to traditional equipment. This technical solution effectively solves the problem of separating heterogeneous components in crushed waste household appliances, providing pretreatment assurance for subsequent metal recycling and plastic sorting processes, and greatly improving recycling efficiency.
[0043] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
