Description

Technical Field

[0001] The present invention belongs to the technical field of casting equipment, and particularly relates to a centrifugal casting feeding device. Background Art

[0002] In the field of centrifugal casting, especially in the production process of composite materials such as fiberglass, the precise and efficient transportation of raw materials is a key link to ensure product quality and production efficiency. At present, the widely used centrifugal casting feeding method in the market mainly relies on a dragon conveyor device, which pushes raw materials such as quartz sand forward through the rotational movement of a spiral tube inside a wear-resistant rubber tube. Although such equipment meets the basic transportation requirements to a certain extent, it exposes many deficiencies in actual applications, seriously restricting production efficiency and equipment reliability.

[0003] First of all, the feeding efficiency of the dragon conveyor device is generally low. Due to the large frictional resistance between the spiral tube and the pipe wall, and the interaction between raw material particles such as quartz sand, serious power loss occurs during transportation, making it difficult to increase the feeding speed and difficult to meet the needs of mass production.

[0004] Secondly, this device is prone to blockage. Especially when dealing with raw materials with larger particles or poor fluidity, due to the design limitations of the spiral tube, it is impossible to effectively avoid the accumulation and blockage of raw materials, which not only affects the continuity of production but also increases the difficulty of cleaning and maintenance.

[0005] Furthermore, the durability of the dragon conveyor device is poor, it is easy to be damaged and inconvenient to replace. Working in a high-temperature and high-wear environment for a long time, both the spiral tube and the wear-resistant rubber tube are easily worn, resulting in a shortened equipment life. Once damaged, due to the complexity of the equipment structure, replacement and repair not only consume time and effort but also increase production costs.

[0006] In addition, the high energy consumption problem of the dragon conveyor device cannot be ignored. Due to low transportation efficiency and large power loss, this device consumes a large amount of electric energy during operation, which does not conform to the current production concept of energy conservation and environmental protection.

[0007] In view of the many shortcomings of the above-mentioned existing technologies, the present invention aims to provide a simple and efficient raw material transportation device designed specifically for fiberglass centrifugal casting feeders, especially for reliably transporting a large amount of raw materials in a narrow space.
