[0041] See Figure 1 An embodiment of the present invention provides an adjustable stepped plate vibrating fluidized bed, including a lower shell 1 and an upper shell 2. Multiple stepped plates 3 are connected to the lower shell 1, and a distribution plate is provided between each stepped plate 3. The distribution plate is located in the vertical section of the stepped plate 3, and the distribution plates between each stepped plate 3 are connected by hinges. In this embodiment, the adjustable distribution plates between each stepped plate 3 are connected by hinges, allowing for flexible adjustment, and airflow passes through the bottom of the stepped plate 3 to prevent material from adhering to the stepped plate.

[0042] The upper housing 2 is provided with a hydraulic push rod 4, and multiple linkage rods 5 are connected to the hydraulic push rod 4. The multiple linkage rods 5 are connected to each of the distribution plates. The linkage rods 5 and the hydraulic push rod 4 are used to flexibly adjust the distribution plates to change the opening ratio of the bed and avoid material leakage from the distribution plates.

[0043] In this embodiment, a stepped distribution plate design is adopted, with a height of 30-80mm between each step plate 3, which facilitates the loosening of materials during the feeding process; a certain thickness of PTFE is sprayed on the step plate 3 to ensure that the step plate is smooth and to prevent materials from sticking.

[0044] In this embodiment, the lower housing 1 is also provided with a vibration motor transmission mechanism 6 for driving the upper housing 2 and the lower housing 1; a shock absorption device 7 is also provided below the lower housing 1.

[0045] In this embodiment, the lower housing 1 is provided with an air inlet chamber, which is provided with a plurality of air inlet chamber partition plates 101 to divide the air inlet chamber into multiple partitioned air inlet chambers. Each partitioned air inlet chamber is provided with a hot air inlet 102 and a cold air inlet 103 respectively. The upper housing 2 is provided with multiple upper housing hot and cold chambers, and partition plates 201 are provided between each upper housing hot and cold chamber. Each upper housing hot and cold chamber is provided with a hot air outlet 202 and a cold air outlet 203 respectively. The upper housing 2 is also provided with a feed inlet 204, which facilitates flexible gas adjustment and comprehensive utilization of exhaust gas.

[0046] In this embodiment, the upper shell 2 and the lower shell 1 are provided with a discharge box 8 and a discharge port 9 at their ends.

[0047] Another embodiment of the present invention provides a method for drying and dehydrating rubbery materials, including the adjustable stepped plate vibrating fluidized bed as described above, the drying and dehydration method including the following steps;

[0048] Start the vibration motor transmission mechanism 6 to drive the upper housing 2 and the lower housing 1 to move;

[0049] The wet rubber material passes through the drying zone and cooling zone in sequence through the multi-layer ladder plate 3. Hot air enters through the hot air inlet 102, passes through the ladder plate 3, comes into contact with the material, and is discharged through the hot air outlet 202. Cold air enters through the cold air inlet 103, passes through the ladder plate 3, comes into contact with the material, and is discharged through the cold air outlet 203. Finally, the dry material is discharged from the discharge box 8.

[0050] When the machine is started, the vibration motor transmission mechanism 6 is activated, the distribution plate is closed through the linkage rod 5 and the hydraulic push rod 4, and low-pressure fire extinguishing steam is introduced to quickly exhaust the air.

[0051] Rubber material is added through the feed inlet 204, and hot air and cold air are introduced through the bottom air inlets to dry and cool the material. The distribution plate is opened by the linkage rod 5 and the hydraulic push rod 4 to make the bed opening rate 1-3.5%.

[0052] In summary, the adjustable stepped plate vibrating fluidized bed provided by this invention has a distribution plate located in the vertical section of the stepped plate, which avoids material leakage and reduces the equipment failure rate; the stepped plate is coated with a certain thickness of PTFE to ensure that the stepped plate is smooth and prevents material from sticking; the adjustable distribution plates between each stepped plate are connected by hinges, which can flexibly adjust the opening ratio of the distribution plate, and the hot air volume is low, thus achieving energy saving.

[0053] The adjustable stepped plate vibrating fluidized bed provided by this invention is mainly suitable for drying and dehydrating rubbery materials. It can also be applied to low-viscosity lumpy materials. The automatic adjustment function of the opening ratio is achieved by opening the distribution plate through the linkage rod and hydraulic push rod. The distribution plate is set at the vertical end of the stepped distribution plate to avoid the problem of material falling into the bed. At the same time, the step plate is cleaned by blowing. The vibration and the step plate design promote the uniform forward movement of the material. The hot air volume is low and the heat utilization efficiency is improved.
