Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying beds, in particular to a fluidized drying bed with uniform drying. Background Art
[0002] In the chemical, pharmaceutical, food and other industries, fluidized bed drying technology is widely used due to its high efficiency, continuity and strong adaptability. The working principle of the fluidized bed dryer is to fluidize the granular material by passing a gas with a certain speed (such as hot air) into the bed, so as to achieve the purpose of uniform drying. However, in the existing fluidized bed drying technology, the problems of uneven feed distribution and material accumulation have always been the key factors restricting its drying uniformity.
[0003] When the material enters the fluidized bed, due to the influence of various factors such as the feeding method, material properties and equipment structure, the distribution of the material in the bed is often difficult to reach an ideal state. This uneven distribution will cause material accumulation in the bed, and then form a local uneven drying phenomenon, which will not only affect the drying efficiency, but also have an adverse effect on product quality. In addition, the steam generated by drying may contain some material particles, and direct discharge will affect the external environment. In order to solve the above problems, it is convenient to evenly disperse the material entering the fluidized bed, so as to avoid its accumulation inside the fluidized bed and affect the drying of the material. At the same time, the discharge of steam is improved to avoid its pollution to the external environment. For this reason, we propose a fluidized drying bed with uniform drying. Utility Model Content

[0030] Furthermore, the air guide hood 4 is in the shape of a quadrangular pyramid as a whole, and a number of anti-fall inclined plates 8 for preventing condensed water from dripping are fixedly installed on the inner wall surface of the air guide hood 4. The setting of the anti-fall inclined plates 8 can effectively prevent condensed water from dripping directly on the material, thereby ensuring the drying quality of the material.
[0031] Furthermore, a number of dividing blocks 9 for dividing materials are equidistantly fixedly installed inside the feed port 5. The ends of the dividing blocks 9 are all smooth curved surfaces. Through the arrangement of the dividing blocks 9, the material can be evenly dispersed and the accumulation of the material can be reduced, so that the material can reach a better dispersed state before entering the drying bed, which provides favorable conditions for subsequent uniform drying.

[0035] Instructions
[0036] When in use, first start the hot air blower to preheat the inside of the bed 1, then start the driving motor, and drive a group of connecting gears 12 to rotate through the driving motor, and through the connection between the connecting gears 12, drive the remaining two groups of connecting gears 12 to rotate together with it, so that the rotation of the connecting gears 12 drives the bulk material plate 10 connected to the top to rotate together with it, and the rotation of the bulk material plate 10 drives the bulk material rod 11 to rotate, and then the material to be dried is put into the inside of the bed 1 through the feed bin 5. When the material enters the feed bin 5, it will be divided by the separation of the dividing blocks 9. After that, when the material passes through the bulk material plate 10, it is scattered by the bulk material rods 11 and falls into the inside of the bed 1. On the drying air net 3, material accumulation is reduced and drying efficiency is improved. At this time, after the material falls on the drying air net 3, it will roll down along the inclined setting of the drying air net 3 to flow out to the discharge bin 6, thereby completing the drying. The water vapor generated by the drying material will enter the interior of the guide box 13 through the convergence of the guide cover 4, and then flow out through the guide pipe 14. When passing through the filter screen 15, the particles inside are filtered and fall into the collection box 17, which is convenient for cleaning later. The device cooperates with the above-mentioned structures to evenly disperse the material entering the fluidized bed, thereby avoiding its accumulation inside the fluidized bed and affecting the drying of the material. At the same time, the discharge of steam is improved to avoid its pollution to the external environment, which is more environmentally friendly and practical.
