Therefore, there is an urgent need for a valve nozzle structure for packaging refractory materials that can dredge the feeding to ensure the smooth falling of the refractory materials. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a valve nozzle structure for packaging refractory materials, which can disperse the refractory materials falling into the feeding pipe, make them fall evenly, and avoid the influence of factors such as humidity and viscosity of the refractory materials on clogging the feeding pipe during the feeding process and affecting the normal feeding and packaging.

Description of the Drawings

[0016] Figure 1 is a schematic structural diagram of an embodiment of the present application;

[0017] Figure 2 is a cross-sectional view of the blanking pipe of the embodiment of the present application. Detailed Embodiments

[0018] The following will clearly and completely describe the present utility model in conjunction with the drawings and embodiments:

[0019] As Figures 1 to 2As shown in the figure, a valve nozzle structure for packaging refractory materials according to the present utility model includes a material conveying cylinder 1. The material conveying cylinder 1 is a hopper structure with a larger upper part and a smaller lower part to facilitate the centralized falling of refractory materials. A wear-resistant lining 2 is arranged inside the material conveying cylinder 1 to reduce the wear caused by refractory materials to the inner wall of the material conveying cylinder 1 and ensure its service life. The bottom of the material conveying cylinder 1 is connected to a blanking pipe 3 in a communicating manner. The blanking pipe 3 is a cylindrical structure that is vertically penetrated up and down. The blanking pipe 3 is connected to the material conveying cylinder 1 through a flange arranged on the opposite end faces. A support frame 4 is arranged inside the blanking pipe 3. The support frame 4 preferably has a cross-shaped structure, and the longitudinal section of the support rod forming the support frame 4 is triangular to prevent the accumulation of refractory materials at its top during the falling process. A conical guiding part 5 is rotatably arranged on the support frame 4. The guiding part 5 is located in the middle of the blanking pipe 3. The rotating shaft 12 at the bottom of the guiding part 5 passes through the support frame 4 and is provided with a driven bevel gear 6. A driving rod 8 driven by a motor 7 is arranged on the blanking pipe 3. A driving bevel gear 9 meshing with the driven bevel gear 6 is arranged at the end of the driving rod 8. During operation, the motor 7 drives the driving rod 8 to rotate. The driving bevel gear 9 will mesh with the driven bevel gear 6 to rotate, driving the guiding part 5 to rotate, thereby dispersing the refractory materials falling into the blanking pipe 3, making the refractory materials fall dispersedly in the blanking pipe 3, avoiding the accumulation and blockage of refractory materials in the blanking pipe 3, and ensuring the smooth progress of the packaging work. In this embodiment, the guiding part 5 is preferably further provided with a protrusion 10 with a tip to further improve the effect of dispersing refractory materials with higher viscosity and humidity, and ensure the smooth discharge of refractory materials from the blanking pipe 3.

[0020] Furthermore, a cleaning brush 11 is arranged on the rotating shaft 12. In the initial state, the cleaning brush 11 is in contact with the inner wall of the blanking pipe 3. The cleaning brush 11 is used to timely clean the refractory materials adhered to the inner wall of the blanking pipe 3, avoiding the situation that the accumulation of too much refractory materials on the inner wall of the blanking pipe 3 affects the blanking space inside the blanking pipe 3 and causes blockage. Specifically, two sets of cleaning brushes 11 are arranged up and down. Each set has two cleaning brushes 11 symmetrically arranged. The two sets of cleaning brushes 11 are respectively arranged on the rotating shafts 12 on both sides of the support frame 4 to ensure the cleaning range of the blanking pipe 3.

[0021] Furthermore, a funnel-shaped material receiving port 15 is arranged at the top of the blanking pipe 3, and the size of the bottom end of the material receiving port 15 is smaller than the size of the bottom of the guiding part 5 to ensure that the refractory materials first fall onto the guiding part 5 and are dispersed after contacting and colliding with the guiding part 5. A funnel-shaped discharging port 16 is arranged at the bottom of the blanking pipe 3 to facilitate the centralized discharge of the dispersed refractory materials from the bottom of the blanking pipe 3 finally, which is convenient for receiving and packaging the refractory materials.

[0022] Furthermore, a protective cover 13 is connected to the bottom of the support frame 4. The protective cover 13 is sleeved outside the driving bevel gear 9 and the driven bevel gear 6. The rotating shaft 12 and the driving rod 8 are rotatably connected to the protective cover 13 through bearings. The setting of the protective cover 13 can prevent refractory materials from falling on the driving bevel gear 9 and the driven bevel gear 6, which may have an adverse effect on the normal transmission of the two. In addition, protective cover plates 14 are provided at the top of the driving rod 8 and the top of the cleaning brush 11. The protective cover plate 14 is preferably made of angle steel structure, and the ridge line of the protective cover plate 14 is arranged upward, which can prevent refractory materials from falling into the cleaning brush 11 and having an adverse effect on the cleaning work of the cleaning brush 11; the protective cover plate 14 provided on the driving rod 8 can protect the driving rod 8 and reduce the erosion and wear caused by hard refractory materials to the driving rod 8.

[0023] When the present utility model is in use, when the humidity and viscosity of the refractory material are relatively small, the motor 7 may not be turned on temporarily or may be selectively turned on at regular intervals to drive the diversion part 5 to rotate, so as to realize the dispersed falling of the refractory material; when the viscosity and humidity of the refractory material are relatively large, the motor 7 can be turned on throughout the feeding process to drive the diversion part 5 to rotate, so as to realize the dispersed falling of the refractory material. At the same time, the inner wall of the feeding pipe 3 is cleaned in real time by using the cleaning brush 11 to avoid the adhesion of the refractory material on the inner wall of the feeding pipe 3 and improve the smoothness of the feeding.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
