Description
Technical Field
The invention belongs to the technical field of feeding, and particularly relates to a material feeding method.
Background
The current solid powder feeding generally adopts an intermittent feeding and intermittent metering feeding system, and the system is only applicable to fixed places (such as a concrete preparation station), has huge system volume, low average feeding capacity and high investment, and can only meet the existing production requirements.
The feeder is a feeder in a general sense, and the feeder is divided into an open type feeder and a closed type feeder, which are commonly known as an electromagnetic vibration feeder, a bar vibration feeder and a screw feeder. The material arching refers to the phenomenon that the material forms an arch shape at a discharge port of a storage bin to prevent discharging. When the material is discharged from the bin, because friction force and binding force exist between particles and between the particles and the inner wall of the bin, a dome is formed above the discharge port, powder is prevented from smoothly entering the discharge port, and no material can be discharged from the discharge port. The arch breaker is a special device for preventing and eliminating the phenomena of arch formation, wall sticking, retention and the like of materials at various storage bins, storage bins and pipeline branching positions. Common arch breaking devices include vibration mechanical type and compressed air type. The vibration mechanical arch breaking device is generally arranged on the wall of the storage bin, strong vibration brings rapid high-frequency vibration to the whole mechanism, friction force and cohesive force among particles and between the particles and the inner wall of the storage bin can be destroyed to a certain extent, and arch breaking is realized to help powder particles to flow. However, the defects are obvious, firstly, because the intensity of vibration is fixed and not adjustable, the arch breaking effect is unreliable, and the second long-term vibration causes the fatigue of the stock bin plate, thereby the phenomena of cracking or welding at the welding position and the like are caused, and the safety of the stock bin is influenced; the compressed air arch breaking mode introduces a gas medium into the powder particles, so that the application range is greatly limited by physical parameters of powder materials, such as some inflammable and explosive materials, the water content and the oxygen content of the gas are limited, and meanwhile, the flow of the arch breaking airflow is difficult to control, so that the arch breaking effect is also unreliable. The two modes are not ideal in practice, and when the vibration feeding is used for breaking the arch, the solid powder material at the vibration part is only broken, so that the high-order arching far from the vibration point is difficult to be effectively broken or disturbed in advance, the arching still often occurs in the actual production, and the feeding is often interrupted. . The prior feeding arch breaking is usually carried out after arch breaking, so that the whole feeding process cannot be stabilized. Because of the interruption of feeding, batch production modes are mostly adopted, and the accuracy of continuous production is difficult to ensure due to poor feeding continuity and accuracy, so that the quality and performance of the product can be influenced. In the construction process of new materials for cast-in-situ solid waste treatment, a solid powder feeding device with higher feeding requirements, high feeding precision, continuous and stable feeding and controllable flow is needed to be provided, so that the requirement of sufficient productivity can be ensured, and the requirements of popularization and development are met. Therefore, development of a continuous stable feeding system capable of realizing solid powder and acceleration of production and realization of a construction process for treating new materials by cast-in-situ solid wastes are very urgent needs. The invention is an innovative activity carried out to solve the problem.
