Introduction to the structural composition and impact of fluidized bed inside cement tanker
The powder material transporter is also known as the bulk cement transporter or the bulk cement tanker. Today, the structure of the internal fluidized bed of the upper tank is introduced. Currently, there are three types of fluidized beds on the market, V-type. The fluidized bed structure, the air bag fluidized bed structure, and the Y-type fluidized bed structure with the largest amount of use, and the Y-type fluidized bed are also called the W-type fluidized bed. This fluidized bed structure transport vehicle can effectively reduce the residual rate of bulk cement. Whether the design of the internal fluidized bed structure of the bulk cement transporter tank is reasonable, determines the performance of the whole vehicle - the speed of the unloading ash, the level of the residual ash rate, the size of the effective volume ratio, and the light weight of the curb.
Fluidized bed structure inside the tank
The fluidized bed is composed of a perforated plate and a side slide plate. The perforated plate is supported by two beams, which are opened in the beam to facilitate gas circulation and reduce the self-weight; the side slide plate is supported by a small crescent plate, and the hole is also opened on the crescent plate. Conducive to gas circulation and reduce its own weight, so as to ensure that the fluidized bed can withstand the weight of the contained powder material, prevent the weld seam cracking of the fluidized bed, and minimize the dead weight.
The height of the ash discharge bell of the bulk cement transporter is very important for the ash discharge effect. The fluidized structure under the fluidized bed bell mouth is “V†type and “broadband†type, so the gap between the periphery of the bell mouth and the bottom surface is one. The variable value, between 40-55mm, is not conducive to the flow of the powder material, and has a great influence on the discharge speed and the residual ash.
In order to further improve the efficiency of unloading, a prismatic plate is installed under the discharge bell mouth so that the underside of the bell mouth is a flat surface, and the gap between the periphery of the bell mouth and the bottom surface is rationally designed, thereby facilitating uniform flow of the powder material, thereby The discharge speed is faster and the remaining ash is lower.
Internal structure impact
The structural parameters of the internal fluidized bed of the bulk cement truck mainly include the lateral inclination and longitudinal inclination of the side slide and the width of the fluidized bed. The larger the inclination angle is, the narrower the width of the fluidized bed is, the better the discharge effect is, but the effective volume ratio is low, and the preparation quality is large; on the contrary, the effective volume ratio is large, but the effect is poor, so the choice of angle should take into account various factors. balance.
The inclination of the fluidized bed depends on the performance parameters of the powder to be transported, mainly the angle of repose of the powder material. The general roll angle is the angle of repose, the longitudinal inclination is about 1/3 of the angle of repose, and the angle of repose of the cement is 40-48. Degree, so our company has optimized the fluidized bed (roll angle, longitudinal inclination, fluidized bed). When the tower height is 18 meters, both the discharge speed and the residual ash rate have reached the domestic advanced level. Higher than QC/T 560-2010 industry standard regulations. The fluidized bed is both a component that fluidizes the powder material and a load bearing component of the tank. The powder material in the tank needs to be carried by the fluidized bed, so the internal structure of the fluidized bed must be able to withstand the weight of the material in the tank. However, if the structure is too solid, the quality of the whole preparation is large, so the internal structure must be reasonably arranged, and it must be carried, ensuring that the cracking of the weld seam does not occur during the operation, and the self-weight is reduced.
Lingyu series concrete mixer trucks follow the popular style of Europe and the United States, and the shape of the whole car is chic and beautiful. The structure is compact and reasonable. The tank material is made of high-quality steel from well-known domestic steel mills. Different types of special steels are used for different parts of the top, and the blades and tanks are thick and designed to wear synchronously. (Specific explanation: the tank body and the blade are made of low-alloy wear-resistant steel with better wear resistance, the upper arm of the top is made of rectangular tube steel with better tensile strength, and the connecting part of the chassis is made of cast alloy steel with higher hardness and strength.)
The use of CNC plasma equipment and international leading tooling fixtures to ensure the precision of the manufacturing of components. The key welds are CNC automatic welding to ensure the weld strength. Modular design of product structure, assembly line operation, fully guarantee the consistency of batch product quality. . The structural parts are sprayed and pretreated; the painting is carried out in accordance with the luxury passenger car painting process. The industry-leading process effectively guarantees the quality of the entire vehicle.
The Lingyu series concrete mixer truck covers all the products in the mixing industry. The chassis mainly adopts the special chassis of concrete mixer trucks such as Dongfeng, Zhongqi, Shaanxi Automobile, Auman, Jiefang, United Truck, Jianghuai, Hongyan, Beiben, Dayun, Hino, Mitsubishi and Isuzu. And different top-loading manufacturing solutions are tailored to different chassis requirements to achieve the best match of the whole vehicle, and truly achieve the widest range of products.
