When the user transports sludge and other materials with a certain viscosity, the sludge basically contains some other types of sundries and massive stones. If you use a common type of screw conveyor, it is easy to break the screw blade, or Winding on the helical shaft will affect the later use of the equipment. The shaftless screw conveyor can well solve the problems encountered in use. The shaftless screw conveyor is composed of shaftless screw blades, tanks, motors, reducers and other components. The conveying tank of the machine body is U-shaped design, and there is a cover plate on the tank body to facilitate the washing of the tank body after the sludge is transported. Since the sludge has a certain fluidity, the screw conveyor cannot be tilted too much when the sludge is transported, otherwise the sludge will flow back from the middle area of the screw blade.
The placement of the shaftless screw conveyor is generally placed horizontally, or it can be placed obliquely, but the inclination angle should not be too large, and the inclination angle generally does not exceed 15 degrees. It is mainly due to the limitation of the design of the equipment itself and the limitation of material characteristics. When installing, it can be installed on the platform and docked with other equipment to complete the production process according to the needs. It can also be designed and placed on the ground to fix the equipment to prevent the screw conveyor from shaking during use.
The design of the shaftless screw conveyor is generally made of ordinary steel, and can also be designed with stainless steel according to the needs. It is mainly used in special industries, such as chemical industry and sewage treatment industry. my country's modern sewage treatment has just started, and funds, technology, equipment and land are concentrated on how to build more sewage treatment plants. In addition, many sewage treatment plants are still in the process of construction, and the problem of sludge disposal is insufficient. With the operation of urban sewage treatment plants, especially some large and medium-sized sewage treatment plants, sludge cakes of tens of tons and hundreds of tons are produced every day, and some sewage plants produce thousands of tons of mud no matter the weather is good or bad. It needs to be cleaned and disposed of at any time, coupled with the acceleration of urbanization, the farmland that used to absorb sludge has become an urban area, and the problem of sludge disposal has finally been exposed. At the same time, the transportation and treatment of sludge has also become the primary problem. The actual production experiment proves that the shaftless screw conveyor can effectively solve the problem of sludge transportation in ordinary conveying equipment, and has become an important equipment in the process of sludge harmless treatment.
