Description

Technical Field

[0001] This utility model belongs to the field of silicon carbide nozzle manufacturing technology, specifically relating to a silicon carbide nozzle with anti-oxidation effect. Background Technology

[0002] The background technology of silicon carbide nozzles originated from the demand for highly wear-resistant and highly corrosion-resistant materials. Its development has gone through the transformation from traditional ceramics to high-performance silicon carbide materials. It has a wide range of applications, including fluid transportation and spraying operations in industries such as chemical, petroleum, metallurgy, and environmental protection. Due to its excellent oxidation resistance and high temperature resistance, it is particularly suitable for high temperature and high pressure environments, effectively improving industrial production efficiency and equipment service life.

[0003] Application No. 202320052777.7 discloses a silicon carbide nozzle, which includes a connecting pipe and a silicon carbide nozzle body located directly below the connecting pipe. A fixing sleeve is fixedly connected to the bottom of the surface of the connecting pipe, and a pressure ring is fixedly connected to the top of the surface of the silicon carbide nozzle body. A sealing gasket is provided on the pressure ring, and the top of the sealing gasket is attached to the top of the inner cavity of the fixing sleeve. The connecting pipe and the silicon carbide nozzle body are attached to each other on their adjacent sides. A sealing sleeve that cooperates with the fixing sleeve is fixedly connected to the top of the surface of the silicon carbide nozzle body. An auxiliary component that cooperates with the fixing sleeve is provided on the sealing sleeve and the pressure ring. By setting the auxiliary component, the entire assembly process remains simple and convenient while ensuring installation stability and sealing performance. It can be completed simply by docking and rotating, which greatly improves work efficiency. Moreover, the connecting pipe and the silicon carbide nozzle body can be quickly disassembled, which is convenient for maintenance or replacement of the silicon carbide nozzle body.

[0004] In practical use, although the silicon carbide nozzles described in the above documents can be quickly replaced to meet the continuous operation of the production line, there may be instances where the nozzles cannot meet the expected production pressure requirements, which may affect operating efficiency and product quality. At the same time, due to the lack of an effective adjustment mechanism, the nozzles cannot flexibly adjust the spray area of ​​gas or fluid, making them unable to adapt to different process requirements, thus limiting their application range and effectiveness in diverse production environments. Therefore, a silicon carbide nozzle with anti-oxidation effect has emerged. Utility Model Content

[0026] Example

[0027] Reference Figures 1-4 This is an embodiment of the present invention, which provides a silicon carbide nozzle with antioxidant effect, comprising:

[0028] The suction mechanism 100 includes a protective shell 101, a suction port 102 communicating with the side wall of the protective shell 101, a connecting shell 103 fixedly installed at the bottom of the protective shell 101, a support rod 104 fixedly installed on the side wall of the connecting shell 103, a sheath 105 fixedly installed at the end of the support rod 104, and a rotating assembly 106 disposed in the inner cavity of the sheath 105.

[0029] The ejection mechanism 200 includes a collar 201 connected to the inner cavity of the connecting housing 103 via a bearing, a lever 202 fixedly installed on the side wall of the connecting housing 103, a groove 203 formed on the side wall of the collar 201, and an adjustment assembly 204 provided on the inner wall of the groove 203.

[0030] Specifically, the rotating assembly 106 includes a connector 106a disposed in the inner cavity of the sheath 105, and a drive shaft 106b fixedly mounted on the end of the connector 106a. The rotating assembly 106 also includes an intake impeller 106c sleeved on the side wall of the drive shaft 106b, and a balance impeller fixedly mounted on the surface of the drive shaft 106b.

[0031] Furthermore, the connector 106a can be powered by an external motor. When the drive shaft 106b rotates, the suction impeller 106c, in conjunction with the suction shell, can draw in fluid or air. When used with the counterbalance impeller with blades arranged in opposite directions, a stable pressure can be formed within the protective shell 101, while increasing the velocity of the drawn-in fluid or air. The surfaces of the balance impeller, suction impeller 106c, and drive shaft 106b are coated with Teflon, providing high oxidation resistance for the interior of the device.

[0032] The rotating assembly 106 also includes an ejector impeller 106e fixedly mounted on the side wall of the balance impeller, and a guide head 106f fixedly mounted on the end of the drive shaft 106b.

[0033] Preferably, the impeller 106e is configured to facilitate the extraction of fluid or air from the protective housing 101, and the guide head 106f is configured to facilitate the guidance of the direction of fluid or gas.

[0034] The adjustment assembly 204 includes a slider 204a slidably connected to the inner wall of the slide groove 203, and a connecting block 204b fixedly installed on the side wall of the slider 204a. The adjustment assembly 204 also includes a connecting seat 204c fixedly installed on the side wall of the connecting block 204b, and a limiting ring 204d slidably connected to the inner cavity of the connecting seat 204c. The adjustment assembly 204 also includes a baffle 204e fixedly installed on the side wall of the connecting block 204b, and a guide rod 204f fixedly installed on the side wall of the connecting seat 204c.

[0035] It should be noted that the collar 201 is designed to facilitate adjustment of the nozzle diameter, ensuring that the device can be adjusted according to different processing requirements and making the device easy to use.

[0036] In use, the connector is connected to a power source, which drives the drive shaft 106b to rotate. The drive shaft 106b drives the suction impeller 106c to rotate. The suction impeller 106c, in conjunction with the suction port 102, draws in fluid or gas. Simultaneously, the drive shaft 106b drives the balancing impeller to rotate. The counter-rotating blades counteract the force of the liquid or gas drawn in by the suction impeller 106c. The gas or liquid passes through small holes on the side wall of the sheath 105. When used in conjunction with the protective shell 101, a high-pressure state is formed inside the protective shell 101. The drive shaft 106... While rotating, the ejector impeller 106e rotates, drawing out the high-pressure gas or fluid from the protective shell 101. Guided by the guide head 106f, the gas or fluid is ejected. When the spray range needs to be adjusted, the collar 201 is turned, causing it to rotate. The sliding fit limit ring 204d and guide rod 204f drive the connecting seat 204c to move obliquely. As the connecting seat 204c moves, it drives the baffle to open and close, thereby adjusting the diameter of the circle formed by the baffle and controlling the spray area of ​​the nozzle.

[0037] In summary, this system achieves efficient power transmission and fluid control, balancing suction and discharge. By adjusting the collar 201 and connecting seat 204c, the nozzle area can be flexibly controlled, ensuring high efficiency while adapting to different needs, improving operational flexibility and usage efficiency. The rotating drive shaft 106b of the connector transmits power, and the suction impeller 106c is set in the opposite direction to the balancing impeller to reduce vibration and improve stability. The small hole of the sheath 105 and the protective shell 101 form high pressure, enhancing the discharge force. The guide head 106f guides the fluid to be sprayed in a directional manner, achieving precise operation. The oblique movement of the baffle adjusts the discharge area to meet the needs of different scenarios, improve performance, reduce maintenance costs, extend service life, and provide users with a convenient, efficient, and stable operating experience.
