As a new type of equipment, flash drying has been widely used in the titanium *** industry. It is currently used in the titanium *** industry. The commonly used models are 1400 and 1600 flash dryers, which can meet the quality of titanium ***. Claim. In the titanium *** industry company will continue to adhere to scientific and technological innovation, and constantly improve the company's innovation capabilities, and continuously strive for the sustainable development of the titanium industry and the drying industry.
The flash dryer is mainly composed of an air inlet system, a heating system, a feeding system, a drying host, a receiving dust removal system, an exhaust system, and a control system. During operation, the wet material enters the drying chamber by the screw feeder, and the material meets the hot air rotating at high speed in the drying chamber, and the fine powder material is moved by the hot air to the upper end of the drying chamber, and the material that cannot be taken falls at the bottom of the drying chamber. It is broken by the crushing device at the bottom, the material is quickly dispersed, and the contact area between the material and the hot air is rapidly increased. Under the action of centrifugal force (with a classification device at the top), the product that reaches the degree of dryness and a certain degree of fineness is blown out of the classifying device, and the material is quickly dried in the process.
The flash dryer has the advantages of high technology content, high standardization, environmental protection, safety, low consumption, simple maintenance, etc. In the design structure:
1 The number of revolutions of the stirring shaft is controlled by a stepless speed regulating motor. According to the product particle size requirements, different speeds are selected. The faster the stirring shaft speed, the smaller the particle size of the product.
2 The top of the dryer is equipped with a classifier. By changing the pore diameter of the classifier and the height of the classification section, the air flow rate is changed to control the particle size and quantity leaving the dryer, the final moisture content and the residence time of the material in the drying section.
3 The bottom of the dryer is provided with an inverted cone structure, so that the flow cross section of the drying gas is gradually enlarged from the bottom to the top, the bottom airflow is relatively large, and the upper airflow is relatively small, thereby ensuring that the large particles in the lower portion are in a fluidized state, and the upper portion is small. The particles are also in a fluidized state, and the hot air is rotated along the vertebral body, the bottom wind speed is increased, the length of the cantilever portion of the stirring shaft is reduced, the safety and reliability of the operation are increased, and the bearing can be placed outside the machine to effectively prevent the bearing from being at a high temperature. Work in the area, thus extending the life of the bearing.
4The scraping tooth is provided with scraper. When the material is crushed by the stirring tooth, it is thrown to the machine wall and bonded to the wall. If it is not scraped in time, the equipment will vibrate in severe cases, and even the stirrer will be suffocated. . A scraper is arranged on the stirring tooth to peel off the material adhering to the machine wall in time to avoid sticking.
The screw conveyor speed of the 5 feeder is controlled by the inorganic speed control motor. The feed rate is controlled according to the nature of the material and the drying process parameters.
6 The equipment is compact in structure, small in floor space, integrated in drying, crushing and grading. It is an organic combination of swirling technology, fluidization technology, spray technology and convection technology. It does not need to be crushed and sieved after drying, which simplifies. The production process saves power and equipment costs.
