DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, the utility model provides a fluidized bed for granulating, cooling and collecting cable material fragments, characterized in that it includes a fluidized bed body 1, a fluidized bed bracket 2, an air inlet disperser 3, a centrifugal fan 4, an electromagnetic vibrator 5 and a cyclone separator 6. The fluidized bed bracket 2 is used to support the entire fluidized bed and is fixed to the ground by bolts. The fluidized bed body 1 can be detachably fixed on the fluidized bed bracket 2. The air inlet disperser 3 is located below the fluidized bed body 1 and is conductively connected to the fluidized bed body 1 and can be detachably fixedly connected. A material inlet 11 and a first air outlet 12 are provided on the fluidized bed 1, an air inlet 31 is provided on the air inlet disperser 3, and the outlet of the centrifugal fan 4 is connected to the air inlet 31, so as to provide airflow to drive the material in the fluidized bed to move and realize cooling and separation of crushed particles; the inlet of the cyclone separator 6 is connected to the first air outlet 12, so as to collect and separate crushed particles rising with the airflow; a crushed particle outlet 61 and a second air outlet 62 are provided on the cyclone separator 6, and an electromagnetic vibrator 5 is located below the air inlet disperser 3, so as to stably and continuously transport the material into the fluidized bed.

[0024] Furthermore, the material inlet 11 is located in the middle of the fluidized bed 1, for receiving the material from the external fan, and the first air outlet 12 is located on the top side wall of the fluidized bed 1. There are two cyclone separators 6, which are respectively arranged at the first air outlet 12 on both sides above the fluidized bed 1, for collecting and separating the crushed particles rising with the airflow. A retaining ring is provided in the cyclone separator 6 to promote the centrifugal separation of the crushed particles, and the crushed particles flow out from the crushed particles outlet 61 at the bottom, while the airflow is discharged from the second air outlet 62 at the top.

[0025] A support plate 21 is provided below the fluidized bed support 2, and the electromagnetic vibrator 5 is fixed on the support plate 21 and is equipped with a rubber anti-skid and anti-vibration device.

[0026] A perforated plate 7 is provided at the connection between the fluidized bed 1 and the air inlet disperser 3. The aperture of the perforated plate 7 is preferably 2.5 mm, which is used to evenly disperse the air inlet into the fluidized bed 1. A level meter 8 is provided at the bottom of the fluidized bed 1 to monitor the material height and control the feed amount.

[0027] During use, the material is delivered to the material inlet 11 of the fluidized bed 1 through other fans. When the material reaches a certain height in the fluidized bed, the centrifugal fan 4 is turned on. At this time, the material in the fluidized bed is constantly and irregularly jumping. At this time, the crushed particles in the material have a very light specific gravity and enter the cyclone separator 6 along with the exhaust air of the fan. After the crushed particles enter the cyclone separator 6, there is a retaining ring in the cyclone separator 6 to make the crushed particles rotate with the wind. Due to the centrifugal effect of weight, the crushed particles flow out along the crushed particles outlet 61 below the cyclone separator 6, and the air flow is discharged from the second air outlet 62 at the top, thereby achieving the best effect of material cooling and crushed particles collection.

At the same time, the device has a compact structure and is easy to install and maintain, which effectively improves production efficiency and the cleanliness of the workshop environment.
