Buried scraper conveyor is a continuous conveying device for conveying bulk materials such as dust, small particles and blocks, which can be conveyed horizontally, inclinedly and vertically. Bulk material has internal friction and side pressure characteristics. When transporting horizontally, the material is subject to the thrust of the scraper chain in the direction of movement. When the internal friction between the material layers is greater than the external friction between the material and the groove wall, the material moves forward along with the scraper chain. When the ratio of the height of the material layer to the width of the machine groove satisfies certain conditions, the material flow is stable. When transporting vertically, it mainly depends on the arching characteristics of the material. When the material in the closed machine trough is subjected to the thrust of the scraper chain in the direction of movement, and the resistance of the lower part is continuously fed to prevent the upper material from falling, the lateral pressure is generated, thereby increasing the internal friction of the material, When the internal friction force is greater than the external friction between the material and the tank wall and the material self weight, the material is conveyed upward along with the scraper chain to form a continuous material flow. Due to the vibration of the scraper chain during the movement, the material arch of some materials will be at 120°C; the temperature of the hot material conveying material is 100-450°C, and the instantaneous material temperature is allowed to reach 800°C.
The buried scraper conveyor is a kind of continuous conveying equipment that is enclosed in a rectangular cross section of the forehead housing and uses a moving scraper chain to convey powdery, small granular and small pieces of bulk materials, etc. The scraper chain is buried in the material, so it is called buried scraper conveyor.
The moisture content is related to the material's material content and viscosity. Generally, it should be loosened by hands after being hand-kneaded into groups. It is destroyed and sometimes formed, which causes the material to produce a hysteresis for the chain during the transport process, affecting the transport capacity.
Application range and selection principle The buried scraper conveyor mainly consists of a closed section shell (machine groove), scraper chain, drive device and tensioning device and other components. The equipment is simple in structure, small in size, good in sealing performance, convenient in installation and maintenance, capable of adding more materials, multiple points of discharge, more flexible in process selection and arrangement, and in conveying flying, toxic, high-temperature, inflammable and explosive materials. , can improve working conditions and reduce environmental pollution. Buried scraper conveyor has been widely used in chemical, building materials, metallurgy, electric power, food, light industry and transportation departments.
Aluminum machining is the use of CNC machining out, including: drilling, boring, cutting, turning, screw. Product material are: aluminum6061,6061-T6,6063,6083,7075.5052,2017 .In the high-speed machining out of the workpiece has a good finish. Aluminum machining product surface treatment has anode, electroplating, sand blasting, laser engraving LOGO, mechanical drawing, rolling flower, according to the requirements of the drawings on the product anode all kinds of colors such as color, black, red, blue, yellow. We have a special inspection department to carry out inspection, to ensure that each size of products meet the requirements of the drawings, machining aluminum(cnc aluminum) is the most common in mechanical processing, low density, not easy deformation, high precision products. So it is widely used in various industries.
