Description

Technical Field

[0001] This utility model relates to the field of silicon carbide nozzles, and in particular to a novel composite silicon carbide nozzle protection device. Background Technology

[0002] Silicon carbide nozzles are nozzles made of a new ceramic material (silicon carbide). The nozzles mainly cover spiral solid cone nozzles and vortex hollow cone nozzles. The new composite silicon carbide is made of a new ceramic material.

[0003] These nozzles play a crucial role in material spraying in industries such as chemical, metallurgy, and energy. For example, they are used in liquid spray drying in chemical production and gas spray cooling in metallurgical processes. Their stable and precise spraying function is essential for product quality and production efficiency.

[0004] In some high-pressure injection systems, when the injection pressure changes instantaneously or backflow impact occurs, the silicon carbide nozzle vibrates. For nozzles installed by bolt connection, instantaneous vibration may cause the bolts to loosen, thereby affecting the stability of the nozzle. To address this issue, a novel composite silicon carbide nozzle protection device is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a novel composite silicon carbide nozzle protection device, including an installation pipe 1, which is an interface connecting the nozzle 2 to an external system, enabling the nozzle 2 to cooperate with a corresponding feeding or conveying system to achieve the material spraying function. The nozzle 2 is installed on the upper part of the installation pipe 1, which is the key part for achieving material spraying, and can stably spray liquid or gas materials at a specific angle and speed. This technology is prior art, so it will not be described in detail. A protective mechanism is provided on the outside of the nozzle 2, and the protective mechanism includes a protective assembly. The component and the limiting assembly are fixedly installed by bolts 6. The limiting assembly includes a mounting sleeve 31, which is installed on the outside of the nozzle 2 by bolts 6. The inner wall of the mounting sleeve 31 slides on the lower outer side of the nozzle 2. There are two sets of mounting sleeves 31. The upper part of the mounting sleeve 31 has a groove to provide installation space for bolts 6. A fixing block 32 is fixedly connected to the upper side of the middle part of the mounting sleeve 31. Together with the mounting sleeve 31, it provides sliding and installation space for the limiting block 33. The inner walls of the mounting sleeve 31 and the fixing block 32 are slidably connected to the limiting block 33.

[0032] Furthermore, a groove 34 is provided on the outer side of the upper part of the bolt 6. The limiting block 33 cooperates with the groove 34 on the outer side of the upper part of the bolt 6 to limit the bolt 6. During the installation process, when the bolt 6 is inserted into the groove of the mounting sleeve 31, the limiting block 33 is inserted into the groove 34 under the action of the compression spring 35 to prevent the bolt 6 from loosening or falling out and to ensure connection stability. The limiting block 33 is inserted into the inner wall of the groove 34. There are two sets of limiting blocks 33. The two sets of limiting blocks 33 are elastically connected by the compression spring 35. Connecting the two sets of limiting blocks 33 provides elastic restoring force to the limiting blocks 33. The compression spring 35 keeps the limiting blocks 33 under pressure in the direction of the groove 34 to ensure that the limiting blocks 33 can be stably inserted into the groove 34. When it is necessary to disassemble the protective device or adjust the bolt 6, the limiting block 33 can be disengaged from the groove 34 by overcoming the elastic force of the compression spring 35. A pull block 36 is slidably connected to the upper part of the limiting block 33 to facilitate the operator to pull the limiting block 33.

[0033] Reference Figure 2 and Figure 3 The protective assembly includes a protective cover 51, primarily used to protect the bolt 6 from direct external environmental influences. The protective cover 51 covers and seals the upper side of the bolt 6, preventing dust, debris, and other foreign objects from entering. The protective cover 51 is rotatably connected to the inner wall of the mounting sleeve 31 near the groove. A locking block 52 is fixedly connected to the side of the protective cover 51 near the pull block 36. The locking block 52 cooperates with the pull block 36 to position the protective cover 51 in the closed state. The upper part of the locking block 52 slides under the pull block 36. Two sets of limiting blocks 33 are fixedly connected to opposite sides. The baffle 4 slides on the inner wall of the fixed block 32 to prevent foreign objects from entering the sliding area of ​​the limiting block 33. The upper inner wall of the fixed block 32 is provided with a limiting groove 5. The pull block 36 can slide to the inner wall of the limiting groove 5 to limit the limiting block 33, which facilitates the operation of the bolt 6. Multiple sets of bolts 6 are provided. The bolts 6 are inserted into the inner wall of the groove on the mounting sleeve 31 to improve the stability of the connection. Multiple sets of protective components are provided. The multiple sets of protective components are respectively set on the left and right sides of the two sets of mounting sleeves 31 to protect the multiple sets of bolts 6.

[0034] Reference Figure 2 and Figure 4 The upper part of the mounting sleeve 31 is provided with a heat insulation component, which includes a heat insulation shell 53. The heat insulation shell 53 is inserted into the upper inner wall of the mounting sleeve 31. Another set of mounting sleeves 31 is fitted with a heat insulation shell 54. The heat insulation shell 53 and the heat insulation shell 54 are fixedly installed by screws. The inner walls of the heat insulation shell 53 and the heat insulation shell 54 are attached to the outer side of the nozzle 2. The mounting sleeve 31, the heat insulation shell 53 and the heat insulation shell 54 are made of heat insulation material. The heat insulation shell 53 and the heat insulation shell 54 can reduce the impact of instantaneous high heat on the nozzle 2 and improve the service life of the nozzle 2.

[0035] Working principle: In use, first, put the two sets of mounting sleeves 31 into the lower outer side of the nozzle 2. Then, insert multiple sets of bolts 6 into the grooves on the upper part of the mounting sleeves 31 to connect the mounting tube 1 to the nozzle 2. During the insertion of the bolts 6, the pull block 36 is inserted into the limiting groove 5. The two sets of limiting blocks 33 compress the compression spring 35. When the bolts 6 are fully inserted into the grooves, slide the pull block 36 to release the limiting block 33. Under the elastic force of the compression spring 35, the limiting block 33 is inserted into the slot 34 on the upper outer side of the bolt 6 to limit the bolt 6 and prevent the bolt 6 from loosening or falling out.

[0036] During the installation of the mounting sleeve 31, heat insulation shell 1 53 and heat insulation shell 2 54 are respectively inserted into the upper inner wall of the two sets of mounting sleeves 31, and they are fixed with screws so that the inner walls of heat insulation shell 1 53 and heat insulation shell 2 54 are tightly attached to the outside of the nozzle 2 to form a heat insulation layer and reduce the heat transfer when the nozzle 2 is working.

[0037] While the limiting block 33 moves, the pulling block 36 limits the locking block 52 on the protective cover 51, thereby closing the protective cover 51 and covering the bolt 6 to prevent dust, debris and other foreign objects from entering the area where the bolt 6 is located.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
