1. XSG14 alumina rotary flash drying equipment, pseudo-thin diaspore dryer, alumina special dryerOverview:
Rotary flash drying device is a kind of drying equipment that integrates drying technology and fluidization technology, which overcomes the shortcomings of large energy consumption of drying equipment and uneven drying of fluidized bed, and integrates the advantages of both to become an ideal drying equipment with high efficiency, energy saving and fast characteristics. It is especially suitable for the direct drying of paste, filter cake and other materials, which makes up for the lack of low efficiency and small output of rake drying, and changes the complex process of spray drying first dilution and then spray treatment. Over the years, rotary flash dry operation has been widely used in the drying of high-viscosity, high-consistency and familiar paste materials in chemical industries such as light industry, petroleum, chemical fiber, food, mining, coatings, dyes and intermediates. Compared with other dry equipment, the rotary flash drying device has advanced technology, compact equipment, simple operation and convenient maintenance, which strengthens the gas-solid heat transfer effect, greatly shortens the drying time, greatly improves the product output and quality, and the energy-saving effect is very significant.
2. XSG14 alumina rotary flash drying equipment, pseudo-thin diaspore dryer, alumina special dryerConstruction
As shown in the figure below, the rotary flash dryer is mainly composed of several parts, such as hot air distributor, auger feeder, agitator, classifier, rotary drying chamber and so on. The bottom of the drying chamber is provided with an inverted cone structure, and its outer ring is a hot air distributor, which is connected with the hot air inlet, and the hot air is distributed in the outer periphery of the cylinder in a circular shape, and enters the fluidized section in the tangential direction from the slit at the bottom of the simplified body to form a rotating wind field. The annular gap size is the main parameter that directly affects the working condition of the dryer. The inverted cone structure can make the hot air flow section continuously expand from bottom to top, the bottom gas velocity is relatively large, and the upper gas velocity is relatively small, so as to ensure that the large particles in the lower part are in the fluidized state at the same time, and the small particles in the upper part are also outside the fluidized state. In addition, the inverted cone structure also reduces the length of the cantilever part of the stirring shaft, increases the reliability of operation, and can effectively prevent the shaft from working in the high temperature area, thereby prolonging the service life of the bearing. In order to prevent the material from being thrown to the four walls under the action of the agitator, the "stuttering" phenomenon occurs on the four walls, which will lead to the failure to operate normally, the scraper is installed on the stirring tooth, and there is a slight gap with the bottom of the chamber and the wall of the device, which can ensure that the material is peeled off before the firm bond with the wall of the device.
In addition, the mixing speed should also be reasonably selected, and the normal rotation speed is 50"-"500 rpm. The stirring shaft and the bottom of the dryer have a good sealing device. The classifier at the top of the drying chamber is an angled perforated garden-shaped plate. The function of the classifier is mainly to separate and block the materials with large particles and have not yet dried, so as to continue drying, so as to ensure that the requirements of narrow particle size distribution and uniform wet content of the product are met. The pore size and height of the classifier determine the particle size of the dry product, and when the height is constant, the smaller the pore size, the finer the particle size of the product.
