Description

Technical Field

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

[0002] Silicon carbide ceramic layer nozzles are industrial nozzles made using the excellent properties of silicon carbide ceramic materials. They have the characteristics of high hardness, high temperature resistance, excellent corrosion resistance, high bending strength, high thermal conductivity, and low coefficient of thermal expansion.

[0003] In the prior art, patent publication number CN202322248324.4 discloses a reaction sintering silicon carbide desulfurization nozzle, including a feed pipe for feeding and a spray pipe for spraying liquid connected by a sleeve. In this utility model, during installation, the locking block on the spray pipe is aligned with the vertical groove and inserted. When inserted to the bottom of the vertical groove, the locking block is then rotated to slide into the locking part along the horizontal groove. The locking part forms a locking connection with the locking block, thereby connecting the spray pipe and the sleeve together.

[0004] Although the disassembly and assembly parts of the aforementioned silicon carbide nozzle have been optimized by replacing the threaded connection with a snap-fit ​​connection, the overall spray volume of slurry is still relatively large and the atomization effect is not uniform. When replacing the nozzle, the spring rebound force is used to tighten the locking block. The vibration generated during long-term operation will affect the spring force, which in turn will affect the tightness of the locking block and affect the stability of the nozzle. Therefore, we propose a silicon carbide ceramic layer nozzle structure. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a silicon carbide ceramic layer nozzle structure that is easy to install, has a strong stabilizing effect, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a silicon carbide ceramic layer nozzle structure, including an inlet pipe and a nozzle quick-installation mechanism;

[0007] Inlet pipe: It is equipped with a guide shell on its upper side, and outlet pipes are respectively provided on the left and right sides of the guide shell;

[0008] The nozzle quick-installation mechanism includes a nozzle and a threaded tightening assembly. The nozzles are respectively located on the left side of the left outlet pipe and the right side of the right outlet pipe. The threaded tightening assembly also includes an extension rod, a threaded section, a guide section, a first connecting sleeve, and an internal thread. The extension rod is fixedly connected to the opposite inner sides of the two nozzles. The right side of the left extension rod has a threaded section, and the right side of the threaded section has a guide section. The left end of the right extension rod is fixedly connected to the first connecting sleeve, and the inner arc surface of the first connecting sleeve has an internal thread. The installation is convenient, and the overall structure has a strong stability effect after the nozzle is replaced.

[0009] Furthermore, the threaded tightening assembly also includes a vent, which is located on the right side of the first docking cylinder to ensure stable air pressure inside the first docking cylinder.

[0010] Furthermore, the nozzle quick-installation mechanism also includes a docking flange, a plug-in sleeve, a second docking sleeve, bayonets, and locking blocks. The docking flange is fixedly connected to the right side of the left nozzle and the left side of the right nozzle, respectively. A plug-in sleeve is fixedly connected to the right side of the left docking flange, and a second docking sleeve is fixedly connected to the left side of the left outlet pipe. The outer arc surface of the plug-in sleeve is inserted into the interior of the second docking sleeve. A uniformly distributed bayonet is provided on the right side of the right outlet pipe, and a uniformly distributed locking block is fixedly connected to the left side of the right docking flange to achieve the docking and locking function.

[0011] Furthermore, a twisting interface is provided in the middle of the right side of the nozzle on the left side, enabling manual twisting.

[0012] Furthermore, the lower side of the outer arc surface of the inlet pipe is provided with a mounting flange to enable connection to an external water supply pipe.

[0013] Furthermore, spray holes are evenly distributed on the outer arc surface of the two nozzles to achieve uniform spraying.

[0014] Furthermore, the interior of the guide shell has an arc-shaped structure, allowing the limestone slurry to impact the interior of the guide shell tangentially, thus achieving the first straight-line ejection of the slurry.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This silicon carbide ceramic layer nozzle structure has the following advantages:

[0016] 1. When limestone slurry enters, this structure will first impact the arc of the guide shell tangentially. At this time, the limestone slurry will be dispersed and divided into two limestone slurry streams. These two limestone slurry streams will impact the inner arc surface of the nozzle a second time along the guide of the outlet pipe. During the continuous impact, the limestone slurry streams will be dispersed into finer water droplets and discharged through the spray holes on the nozzle. The limestone slurry water droplets sprayed from the nozzle are more uniform.

[0017] 2. This structure uses a threaded connection to tighten the nozzles on both sides. When the plug tube is inserted into the second docking tube and the threaded section is connected to the internal thread, the nozzle on the right side will be locked by the locking block and the locking slot. At the same time, the two extension rods that are locked will tighten the nozzle on the left side in real time. It is easy to install and the entire structure is very stable after the nozzle is replaced. Attached Figure Description

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.

[0024] Please see Figure 1-4 This embodiment provides a technical solution: a silicon carbide ceramic layer nozzle structure, including a liquid inlet pipe 1 and a nozzle quick installation mechanism 4;

[0025] Inlet pipe 1: It is equipped with a guide shell 2 on its upper side. The left and right sides of the guide shell 2 are respectively equipped with outlet pipes 3. The lower side of the outer arc surface of the inlet pipe 1 is equipped with a mounting flange 5 (the surfaces of the inlet pipe 1, guide shell 2 and outlet pipe 3 are all equipped with silicon carbide ceramic layers). The inside of the guide shell 2 is an arc-shaped structure. At this time, the nozzle structure can be installed in the designated position through the mounting flange 5. When the external limestone slurry enters the guide shell 2 through the inlet pipe 1, the limestone slurry will enter the interior of the guide shell 2 from the tangential direction and impact the inner arc surface of the guide shell 2. At this time, the dispersed limestone slurry is divided into two streams and discharged from the two outlet pipes 3 respectively.

[0026] The nozzle quick-installation mechanism 4 includes a nozzle 42 and a threaded tightening assembly 43. The nozzles 42 are respectively located on the left side of the left outlet pipe 3 and the right side of the right outlet pipe 3. The threaded tightening assembly 43 also includes an extension rod 431, a threaded section 432, a guide section 433, a first docking sleeve 434, and an internal thread 436. The extension rod 431 is fixedly connected to the opposite inner surfaces of the two nozzles 42. The right side of the left extension rod 431 is provided with a threaded section 432, and the right side of the threaded section 432 is provided with a guide section 433. The left end of the right extension rod 431 is fixedly connected to the first docking sleeve 434, and the inner arc surface of the first docking sleeve 434 is provided with an internal thread 436. The threaded tightening assembly 43 also includes an exhaust port 435. The exhaust port 435 is located on the right side of the first docking cylinder 434. The nozzle quick installation mechanism 4 also includes a docking flange 41, a plug-in cylinder 44, a second docking cylinder 45, bayonets 46, and locking blocks 47. The docking flange 41 is fixedly connected to the right side of the left nozzle 42 and the left side of the right nozzle 42. The plug-in cylinder 44 is fixedly connected to the right side of the left docking flange 41. The second docking cylinder 45 is fixedly connected to the left side of the left outlet pipe 3. The outer arc surface of the plug-in cylinder 44 is inserted into the interior of the second docking cylinder 45. The right side of the right outlet pipe 3 has evenly distributed bayonets 46. The left side of the right docking flange 41 has evenly distributed locking blocks 47. The right side of the left nozzle 42 has... The nozzle has a twist-out interface 6. The outer arc surfaces of the two nozzles 42 are evenly provided with spray holes. When this nozzle structure is needed, the right-side flange 41 can be manually lifted and fastened to the right-side outlet pipe 3 using the bayonet 46 and locking block 47. Then, the left-side nozzle 42 can be manually lifted, and the insertion sleeve 44 can be inserted into the second insertion sleeve 45. During this process, the guide section 433 first inserts into the first insertion sleeve 434. As the insertion sleeve 44 continues to be inserted into the second insertion sleeve 45, it is obstructed by the threaded section 432 and the internal thread 436. At this point, the left-side nozzle 42 can be manually screwed, and the threaded section 432 will screw into the first insertion sleeve 434. During this process, the first insertion sleeve 434... The air will be discharged through the exhaust port 435, ensuring that the first docking cylinder 434 is always under normal pressure. When the left nozzle 42 is twisted, the right hand can press the right nozzle 42 in real time, so that the locking block 47 locks the locking slot 46 in real time, preventing the right locking block 47 from rotating and thus preventing free rotation. When the threaded section 432 is tightened with the internal thread 436, the locking block 47 locks the locking slot 46, and then the two nozzles 42 are locked by the tightening effect of the thread tightening component 43. The two discharged limestone slurry flows will impact the inner arc surface of the nozzle 42 again. During the impact, the limestone slurry flow will be sprayed along the spray hole on the nozzle 42 to the outside of the structure, forming an umbrella-shaped spray flow. The atomization effect of the spray is strong and the distribution is more uniform.

[0027] The working principle of the silicon carbide ceramic layer nozzle structure provided by this utility model is as follows: When the nozzle structure is needed, the right-side connecting flange 41 can be manually lifted and fastened to the right-side liquid outlet pipe 3 through the bayonet 46 and the locking block 47. Then, the left-side nozzle 42 can be manually lifted, and the insert sleeve 44 can be inserted into the inside of the second connecting sleeve 45. During this period, the guide section 433 is first inserted into the inside of the first connecting sleeve 434. As the insert sleeve 44 continues to be inserted into the inside of the second connecting sleeve 45, it is obstructed by the threaded section 432 and the internal thread 436. At this time, the left-side nozzle 42 can be manually turned. At this time, the threaded section 432 will be screwed into the first connecting sleeve 434. During this period, the air in the first connecting sleeve 434 will be discharged through the exhaust port 435, ensuring that the first connecting sleeve 434 is always under normal pressure. When turning the left-side nozzle 42, the right hand can press the right-side nozzle tightly. Head 42, causing the locking block 47 to lock the locking slot 46 in real time, preventing the right locking block 47 from rotating, and thus preventing free rotation. When the threaded section 432 is tightened with the internal thread 436, the locking block 47 locks the locking slot 46, and then through the tightening effect of the thread tightening component 43, the two nozzles 42 are locked. At this time, the nozzle structure can be installed in the designated position through the mounting flange 5. When the external limestone slurry enters the guide shell 2 through the liquid inlet pipe 1, the limestone slurry will enter the interior of the guide shell 2 from the tangential direction and impact the inner arc surface of the guide shell 2. At this time, the dispersed limestone slurry is divided into two streams and discharged from the two liquid outlet pipes 3 respectively. The two discharged limestone slurry streams will impact the inner arc surface of the nozzle 42 again. During the impact, the limestone slurry stream will be sprayed along the spray holes on the nozzle 42 to the outside of the structure, forming an umbrella-shaped spray stream, and the spray atomization effect is strong and the distribution is more uniform.
