Description

Technical Field

[0001] This utility model relates to the field of ceramic nozzle fixing technology, specifically to a ceramic nozzle fixing structure. Background Technology

[0002] In numerous industrial production and specific application scenarios, ceramic nozzles are widely used in spraying, atomization, cooling, and other fields due to their unique performance advantages, such as high temperature resistance, corrosion resistance, high hardness, and strong wear resistance. For example, in the metal surface spraying process, ceramic nozzles can accurately spray the coating onto the workpiece surface in a specific atomized form, ensuring uniform coating and stable quality. In the high-temperature cooling process of steel smelting, ceramic nozzles can withstand high-temperature environments and stably spray cooling media, achieving effective cooling protection for equipment.

[0003] Because ceramic materials are inherently brittle, they are prone to cracking and damage when subjected to uneven external forces or vibrations. Some fixing structures typically use clamps, bolts, or custom-made fixing frames of specific sizes to install and fix ceramic nozzles. This fixing method makes it difficult to ensure that a uniform force is applied to the ceramic nozzle, which can easily lead to excessive local stress on the ceramic nozzle, causing cracks or even breakage. Furthermore, this fixing structure cannot adapt to ceramic nozzles of different lengths. Vibrations generated during equipment operation further exacerbate this uneven stress, greatly shortening the service life of the ceramic nozzle. In addition, the existing fixing structure is relatively complicated to install and remove ceramic nozzles, requiring the use of multiple tools and taking a long time. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing fixed structures are difficult to ensure uniform stress distribution, which can easily lead to the cracking of ceramic nozzles. Furthermore, they cannot be adapted to nozzles of different lengths, resulting in increased vibration during operation, shortened lifespan, and complicated installation and disassembly.

[0005] To solve the above problems, the technical solution adopted by this utility model is a fixing structure for a ceramic nozzle, including a limiting frame structure and a pressing frame structure, with the ceramic nozzle body sandwiched between the limiting frame structure and the pressing frame structure.

[0006] The limiting frame structure includes a connecting ring, a clamping frame fixed to the lower side of the connecting ring, a circular groove opened on the inner side of the connecting ring, an annular top plate in the circular groove, a threaded connecting cylinder fixed to the lower side of the annular top plate, an adjusting bolt connected to the threaded connecting cylinder and a limiting rotational setting below the connecting ring, and a spring washer sandwiched between the annular top plate and the circular groove.

[0007] The clamping frame structure includes a clamping ring, and several right-angle locking rods are fixed on the lower side of the clamping ring near the edge. The upper side of the connecting ring is provided with locking grooves that correspond one-to-one with the several right-angle locking rods.

[0008] As a further embodiment of this utility model: a connecting pipe is fixed on the upper side of the clamping ring, and a thread is fixed on the outer side of the connecting pipe, which facilitates installation in the required equipment.

[0009] As a further embodiment of this utility model: an annular connecting ear is fixed at the top of the ceramic nozzle body, the ceramic nozzle body is clamped in the clamping frame, and gaskets are provided between the upper and lower sides of the annular connecting ear and the clamping ring and the annular top plate, which can make the ceramic nozzle body clamped more securely and improve the sealing of the installation.

[0010] As a further embodiment of this utility model: several limiting cylinders are fixed on the lower side of the annular top plate, and a limiting rod that cooperates with the limiting cylinders is fixed on the bottom surface of the circular groove, so as to facilitate the stable movement of the annular top plate.

[0011] As a further embodiment of this invention, the length of the opening above the snap-fit ​​groove is greater than the length of the right-angle snap-fit ​​rod, so that the right-angle snap-fit ​​rod can extend into the snap-fit ​​groove.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This application adds a limiting frame structure and a pressing frame structure. The position of the ceramic nozzle body is fixed by the pressing force of the limiting frame structure and the pressing frame structure. The operation is simple, and the position of the annular top plate can be adjusted according to the adjusting bolts to adapt to nozzles of different lengths. Attached Figure Description

[0022] Combined with appendix Figure 1 , 2 4. It can be seen that the structure includes a limiting frame structure and a clamping frame structure. A ceramic nozzle body 1 is sandwiched between the limiting frame structure and the clamping frame structure. An annular connecting ear 1.1 is fixed at the top of the ceramic nozzle body 1. The ceramic nozzle body 1 is clamped in the clamping frame 3. Gaskets 11 are provided between the upper and lower sides of the annular connecting ear 1.1 and the clamping ring 8 and the annular top plate 4, which can make the ceramic nozzle body 1 clamped more securely and improve the sealing of the installation.

[0023] Combined with appendix Figure 2-4 It can be seen that the limiting frame structure includes a connecting ring 2, a clamping frame 3 fixed on the lower side of the connecting ring 2, a circular groove 2.1 opened on the inner side of the connecting ring 2, an annular top plate 4 in the circular groove 2.1, a threaded connecting cylinder 5 fixed on the lower side of the annular top plate 4, an adjusting bolt 6 connected to the threaded connecting cylinder 5 is provided below the connecting ring 2 for limiting rotation, a spring washer 7 is sandwiched between the annular top plate 4 and the circular groove 2.1, several limiting cylinders 12 are fixed on the lower side of the annular top plate 4, and a limiting rod 13 that cooperates with the limiting cylinder 12 is fixed on the bottom surface of the circular groove 2.1 to facilitate the stable movement of the annular top plate 4;

Then observe the fit between the bottom end of the ceramic nozzle body 1 and the bottom end of the clamping frame 3. If there is a gap between the bottom end of the ceramic nozzle body 1 and the bottom end of the clamping frame 3 or the annular connecting ear 1.1 cannot contact the annular top plate 4, the position of the annular top plate 4 can be adjusted by rotating the adjusting bolt 6 so as to control the position of the ceramic nozzle body 1 in the clamping frame 3 so as to adapt to ceramic nozzle bodies 1 of different lengths.

[0026] After adjustment, align the right-angle locking rod 9 with the upper opening of the locking groove 2.2, then insert the right-angle locking rod 9 into the locking groove 2.2, and then rotate the connecting ring 2 and the clamping ring 8 in opposite directions so that the right-angle locking rod 9 can be screwed into the locking groove 2.2 for connection and fixation. Under the elastic force of a pair of gaskets 11, the connection can be made stable.
