They are widely used in metallurgy, chemical industry, construction, energy and other industries. According to the production process, refractory materials can be divided into sintered refractory materials, fused cast refractory materials and amorphous refractory materials. The refractory processing procedures include raw material preparation. Grinding is to grind the raw materials into powder state for subsequent mixing.

Since the threads opened on the surfaces of the two are in opposite directions, the two lifting blocks 8 are driven to move in different directions, and the two lifting blocks 8 move up and down respectively, and then drive the two storage boxes 9 to move up and down. Through this structure, the refractory material can be automatically transported to the top of the feeding box 2.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, four telescopic rods 14 are movably mounted on one end of four dustproof rods 13 respectively, the positions of the two dustproof plates 15 are corresponding, the threads on the surfaces of the first screw rod 6 and the second screw rod 7 are in opposite directions, and the utility model is an automatic feeding device for refractory materials. By setting the dustproof rod 13, the telescopic rod 14, the belt 10 and the weight sensor 16, one end of the two auxiliary rods 5 is connected to one end of the first screw rod 6 and the second screw rod 7 respectively, the transmission of the two auxiliary rods 5 transmits the force to the first screw rod 6 and the second screw rod 7, and the two can rotate at the same time, and the telescopic rod 14 can move up and down at one end of the dustproof rod 13.

[0026] Working principle: Refractory materials refer to materials that can withstand high temperature, wear resistance, corrosion resistance, and chemical erosion in special environments. They are widely used in metallurgy, chemical industry, construction, and energy industries. According to the production process, refractory materials can be divided into sintered refractory materials, cast refractory materials, and amorphous refractory materials. The refractory processing procedures include raw material preparation. Grinding is to grind the raw materials into powder state for subsequent mixing. Mixing is to mix different raw materials in a certain proportion to achieve ideal performance requirements. During this processing, the refractory materials need to be fed in sequence. For normal processing, it is often necessary to manually add the refractory materials repeatedly to the inside of the feeding box 2, and the height of the feeding box 2 is relatively high, and manual feeding is relatively inefficient. It consumes physical energy and is labor-intensive. The efficiency of manual feeding is relatively low, and the refractory material cannot be quantitatively added. During the transportation of the refractory material, the refractory material is exposed for a long time, so a large amount of external dust will adhere to the surface of the refractory material, affecting the quality of the refractory material. For this reason, the refractory material to be added can be filled into the interior of one of the storage boxes 9. At this time, the two storage boxes 9 are in an upper and lower position. After starting the servo motor 11, the first screw rod 6 and the second screw rod 7 are driven to rotate under the action of the belt 10. Since the threads on the surfaces of the two are in opposite directions, the two lifting blocks 8 are driven to move in different directions. The two lifting blocks 8 move up and down respectively, and then drive the two storage boxes 9 to move up and down. Through this structure, the refractory material can be automatically The refractory material is transported to the top of the feeding box 2, and the refractory material is added to the inside of the feeding box 2 along the surface of the blanking plate 12, thereby realizing the automatic feeding of the refractory material. At the same time, the two storage boxes 9 move up and down, thereby shortening the time for feeding the refractory material. The blanking plate 12 is movably hinged to one side of the storage box 9. After gradually separating from the top of the feeding box 2, the blanking plate 12 is gradually turned over. At this time, the refractory material stored in the storage box 9 can fall into the inside of the feeding box 2 from this gap, and the bottom surface of the dustproof plate 15 can be closed with the surface of the storage box 9, so that the two are sealed, which has a dustproof effect and ensures the neatness of the refractory material. One end of the two auxiliary rods 5 is respectively connected to one end of the first screw rod 6 and the second screw rod 7 The ends are connected, and the transmission of the two auxiliary rods 5 transmits the force to the first screw rod 6 and the second screw rod 7, and the two can rotate at the same time. The telescopic rod 14 can move up and down at one end of the dustproof rod 13, and the friction between the two is relatively large. Therefore, when no pressure is applied to the dustproof plate 15, the telescopic rod 14 will remain stable at one end of the dustproof rod 13, thereby ensuring the firmness of the dustproof plate 15. The model of the weight sensor 16 is KWT1D78, which measures the weight of an object based on the piezoresistive effect and the principle of elasticity. Therefore, the weight of the refractory material can be measured, and the gravity is transmitted to the weight sensor 16 through the load-bearing device, and then the elastic body inside the weight sensor 16 is deformed, and an electrical signal proportional to the weight value is output.
