[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580 °C. Refractoriness refers to the Celsius temperature at which a conical specimen of refractory material does not soften and melt under the action of high temperature without load. In the production process of refractory materials, a variety of raw materials need to be mixed and then transported. Generally, a spiral ribbon type continuous mixing feeder disclosed in a patent with the publication number CN116440759A and a mixing storage quantitative distribution feeding and conveying device disclosed in a utility model patent with the publication number CN205842719U are used to mix a variety of raw materials and transport the mixed refractory materials.

[0003] However, it is found in the use process that the existing mixing and feeding equipment has a relatively simple structure, poor mixing effect on raw materials, and large wear of raw materials on the equipment during long-term use, which easily affects the service life of the equipment. Moreover, it is inconvenient to quantitatively transport the mixed refractory materials, resulting in poor practicability. Therefore, there is an urgent need for a novel refractory material mixing feeder to improve the above problems. Summary of the Utility Model

[0005] The novel refractory material mixing feeder of the utility model includes a storage mechanism; it also includes a mixing mechanism and a conveying mechanism. The storage mechanism is installed on the conveying mechanism, and the mixing mechanism is installed on the storage mechanism;

[0006] The mixing mechanism cooperates with the storage mechanism to mix a variety of materials, and the conveying mechanism transports the mixed refractory materials;

[0007] A variety of raw materials are discharged into the storage mechanism through the mixing mechanism, and a variety of raw materials are mixed through the cooperation of the mixing mechanism and the storage mechanism to form refractory materials, and then the refractory materials are quantitatively discharged through the conveying mechanism, thereby improving the practicability of the equipment.

[0008] Preferably, the storage mechanism includes a mixing bin and a filter screen. The mixing bin is installed on the conveying mechanism, and a chamber is provided inside the mixing bin. An exhaust port is provided at the top of the mixing bin, and the filter screen is installed on the exhaust port of the mixing bin. A mixing mechanism transports various raw materials into the mixing bin, causing the various raw materials to mix inside the mixing bin to form refractory materials.
