Description

Technical Field

[0001] The utility model relates to the technical field of refractory material production equipment, in particular to a dust recovery mechanism for refractory material raw material mixing equipment. Background Art

[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. However, defining it only by refractoriness can no longer comprehensively describe refractory materials, and 1580 °C is not absolute. It is now defined that any material whose physical and chemical properties allow it to be used in a high-temperature environment is called a refractory material. Refractory materials are widely used in industrial fields such as metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, and power. They are used in the largest amount in the metallurgical industry, accounting for 50% - 60% of the total output. When producing refractory materials, the raw materials need to be mixed and stirred in a mixing device.

[0003] The existing Chinese patent with the publication number CN214553123U discloses a refractory material mixing device. The key points of its technical solution are as follows: including a bottom plate, the upper surface of the bottom plate is fixedly connected to the lower surface of the first support rod, the upper surface of the first support rod is fixedly connected to the right side of the lower surface of the stirring device, the left side of the lower surface of the stirring device is fixedly connected to the upper surface of the second support rod, the lower surface of the second support rod is fixedly connected to the upper surface of the bottom plate, the upper surface of the bottom plate is fixedly connected to the lower surface of the third support rod, the upper surface of the third support rod is fixedly connected to the right side of the lower surface of the mixing device, and the left side of the lower surface of the mixing device is fixedly connected to the upper surface of the fourth support rod; by setting the stirring device and the mixing device, the stirring device can initially mix the raw materials together, and the mixing device can thoroughly mix the raw materials together, improving the mixing degree of the refractory materials.

[0004] The above-mentioned existing technical solution has the following defects. Although the above technical solution can initially mix the raw materials together through the setting of the stirring device and the mixing device, and the mixing device can thoroughly mix the raw materials together, improving the mixing degree of the refractory materials, in the above technical solution, during the process of mixing and stirring the raw materials, the generated dust will overflow from the feed port, and the above technical solution cannot recover the overflowing dust, and the dust will diffuse around, thus easily causing pollution to the surrounding environment and reducing its environmental protection performance.
