Description

Technical Field

[0001] This utility model relates to the field of gas jetting tools, and more specifically, to a gas jetting device with a multi-nozzle combination. Background Technology

[0002] In the field of gas jetting technology, gas ejectors have extremely wide applications, covering multiple industries such as chemical engineering, environmental protection, and energy, and are used in various process steps such as gas transportation, mixing, and reaction promotion. With the increasing demands for gas jetting performance from various industries, optimizing the performance of gas ejectors has become a key research focus.

[0003] A search revealed prior art documents, such as the "Multi-nozzle Injector with Internal Flexible Connection Structure" (application number 201110247939.4), which solves the problem of damage to internal nozzles and connectors caused by differences in the expansion of the inner and outer sleeves by setting up flexible pipelines to connect the nozzles and the inner sleeve, thus improving the service life of the equipment in high-temperature environments. However, this injector has limitations in terms of jet direction adjustment. Its nozzles are fixed, making it difficult to flexibly adjust the jet direction according to different working conditions, and it cannot meet the diverse needs of gas jet angles in complex working scenarios.

[0004] For example, the patent application No. 202323298656, "High-Efficiency Multi-Nozzle Jet Aerator," primarily addresses the problem of insufficient mixing between wastewater and gas in wastewater treatment. By incorporating jet pipes, jet nozzles, and a mixer, it ensures thorough contact, mixing, and reaction between wastewater and high-pressure gas, thereby improving wastewater treatment efficiency. However, this aerator's structural design does not consider precise independent adjustment of gas flow rate; all nozzles have the same gas flow rate. In practical applications, if different areas have varying gas flow rate requirements, this equipment cannot meet the process requirements. Utility Model Content

[0005] The purpose of this invention is to provide a gas injector with a multi-nozzle combination to solve the problem mentioned in the background art that the injector has limitations in terms of jet direction adjustment, its nozzles are fixed and it is difficult to flexibly adjust the jet direction according to different working conditions, and it cannot meet the needs of diverse gas jet angles in complex working scenarios.

[0006] To achieve the above objectives, this utility model provides a gas injector with a multi-nozzle combination, including an air supply pipe. The lower end of the air supply pipe is connected to an air pump, and the upper end of the air supply pipe is connected to an air jet component. The air jet component includes a fixed shell, a rotating shell is disposed inside the fixed shell, a driving component is installed on the top of the fixed shell, an adjusting air passage is opened on one side of the outer wall of the rotating shell, and several nozzles are installed around the outer wall of the fixed shell. The rotating shell is adjusted to rotate by the driving component, thereby driving and adjusting the air passage to align with the nozzles at different positions to achieve air jet direction adjustment.

[0007] This system uses an air pump to supply gas into the gas delivery pipe, which then enters the jetting component. A drive unit rotates the rotating housing inside the fixed housing, causing the adjustment port on the rotating housing to rotate accordingly. By engaging with nozzles at different positions on the outer wall of the fixed housing, the gas ejection path is altered, thus adjusting the jetting direction.

[0008] Preferably, an expansion port is installed at the top of the gas delivery pipe near the jet component.

[0009] This design incorporates an expansion port at the top of the gas delivery pipe, increasing the cross-sectional area for gas flow before it enters the jet assembly. Based on fluid mechanics principles, this reduces gas velocity, resulting in a more uniform pressure distribution and minimizing turbulence and pressure loss at the connection between the gas delivery pipe and the jet assembly.

[0010] Preferably, the outer wall of the fixed shell is provided with several threaded interfaces, and one end of the nozzle is provided with a threaded end and is threadedly connected to the threaded interface.

[0011] This feature involves the threaded interface on the outer wall of the mounting housing engaging with the threaded end of the nozzle, thus securing the nozzle to the mounting housing via a threaded connection.

[0012] Preferably, the nozzles are arranged in a ring with equal spacing.

[0013] This design features nozzles arranged in a ring at equal intervals on the outer wall of the fixed housing, ensuring that the gas is evenly distributed in space when ejected from each nozzle, creating a symmetrical spray effect.

[0014] Preferably, the driving component includes a drive motor, one end of which is equipped with a drive shaft, the end of which passes through the fixed housing and is fixedly connected to the rotating housing.

[0015] This setting enables the drive motor to rotate after being powered on, and transmits the rotational power to the rotating shell through the drive shaft, causing the rotating shell to rotate inside the fixed shell, thereby achieving the adjustment of the connection between the air inlet and the nozzle.

[0016] Preferably, an annular sealing groove is provided between the fixed shell and the rotating shell, and a corrosion-resistant sealing ring is installed in the annular sealing groove. The corrosion-resistant sealing ring is made of fluororubber or polytetrafluoroethylene.

[0017] This feature involves installing a corrosion-resistant sealing ring in the annular sealing groove between the fixed shell and the rotating shell. During the rotation of the rotating shell, the sealing ring fits tightly against the fixed shell and the rotating shell, preventing gas from leaking out from the gap between them.

[0018] Preferably, the gas pipeline is equipped with a flow regulating valve.

[0019] This feature involves installing a flow regulating valve on the gas pipeline. By adjusting the position of the valve core, the cross-sectional area of ​​the gas flow channel is changed, thereby controlling the gas flow rate.

[0020] Preferably, the gas pipe and jet component are made of corrosion-resistant material, such as polyvinylidene fluoride, polypropylene, or stainless steel.

[0021] The gas supply pipes and jet components are made of corrosion-resistant materials such as polyvinylidene fluoride, polypropylene, or stainless steel. These materials have good corrosion resistance and can resist the erosion of corrosive gases.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] In this multi-nozzle gas ejector, a drive component rotates the housing, adjusting the air inlet to align with nozzles at different positions, thus enabling flexible adjustment of the gas injection direction. Compared to traditional fixed-nozzle gas ejectors, this design can meet the requirements of different material mixing angles in chemical reactions and the variable gas injection direction in waste gas treatment in the environmental protection field, greatly improving the equipment's applicability in complex working scenarios.

[0024] The expansion port at the top of the gas pipeline reduces the gas velocity and pressure distribution when the gas enters the jet component, reducing gas turbulence. Combined with the annular, equally spaced nozzle arrangement, it ensures the stability and uniformity of gas injection, improves gas delivery efficiency, and provides stable power support for various gas-related processes.

[0025] The nozzle and the fixed housing are connected by threads, making disassembly and installation simple and convenient. When the nozzle malfunctions due to wear or blockage, it can be quickly replaced and cleaned. At the same time, the annular sealing groove between the fixed housing and the rotating housing, combined with a corrosion-resistant sealing ring, facilitates the inspection and maintenance of the internal structure while ensuring sealing performance, reducing equipment downtime and maintenance costs.

[0031] 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.

[0032] This utility model provides a gas injector with a multi-nozzle combination, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes an air supply pipe 1, with an air pump 2 connected to the lower end of the air supply pipe 1 and an air jet component 3 connected to the upper end of the air supply pipe 1. The air jet component 3 includes a fixed shell 31, a rotating shell 32 disposed inside the fixed shell 31, a driving component 4 installed on the top of the fixed shell 31, an adjusting air passage 321 opened on one side of the outer wall of the rotating shell 32, and several nozzles 33 installed around the outer wall of the fixed shell 31. The rotating shell 32 is rotated by the driving component 4, which drives and adjusts the air passage 321 to connect with the nozzles 33 at different positions to realize the adjustment of the air jet direction.

[0033] Air pump 2 inputs gas into gas delivery pipe 1, and the gas enters the jetting component 3 through gas delivery pipe 1. The drive motor 41 of the drive component 4 drives the drive shaft 42 to rotate. The drive shaft 42 is connected and fixed to the rotating shell 32, thereby causing the rotating shell 32 to rotate inside the fixed shell 31. The adjusting air outlet 321 on the rotating shell 32 rotates accordingly, and by docking with the nozzles 33 at different positions on the outer wall of the fixed shell 31, the gas ejection path is changed, and the jetting direction is adjusted. This breaks through the limitation of the fixed jetting direction of traditional gas ejectors, and can flexibly adjust the gas jetting direction according to different working conditions. It is suitable for various complex scenarios that require variable jetting angles, such as chemical mixing and waste gas treatment, significantly improving the versatility and adaptability of the equipment.

[0034] In this embodiment, as Figure 1 As shown, an expansion port 11 is installed at the top of the gas pipe 1 near the jet component 3.

[0035] The expansion port 11 at the top of the gas supply pipe 1, near the jet component 3, increases the flow cross-sectional area of ​​the gas before it enters the jet component 3. Based on fluid mechanics principles, this reduces the gas velocity and creates a more uniform pressure distribution, minimizing turbulence and pressure loss at the connection between the gas supply pipe 1 and the jet component 3. This ensures the gas enters the jet component 3 smoothly and uniformly, providing conditions for stable gas injection from the subsequent nozzle 33, improving gas delivery efficiency and injection stability, and avoiding process fluctuations caused by gas instability.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, the outer wall of the fixed shell 31 is provided with several threaded interfaces 311, and one end of the nozzle 33 is provided with a threaded end, which is threadedly connected to the threaded interface 311.

[0037] The threaded interface 311 on the outer wall of the fixed housing 31 mates with the threaded end of one end of the nozzle 33, fixing the nozzle 33 to the fixed housing 31 via a threaded connection. This connection method facilitates the installation, disassembly, and replacement of the nozzle 33. When the nozzle 33 experiences wear, clogging, or other problems, maintenance operations can be performed quickly, reducing equipment maintenance difficulty and downtime. It also allows for easy replacement of nozzles 33 of different specifications according to different process requirements.

[0038] Furthermore, such as Figure 2 As shown, the nozzles 33 are arranged in a ring with equal spacing.

[0039] The nozzles 33 are arranged in a ring at equal intervals on the outer wall of the fixed shell 31, so that when the gas is ejected from each nozzle 33, it is evenly distributed in space, forming a symmetrical spray effect. This ensures that the gas is evenly distributed in the spray area, avoiding situations where the local gas concentration is too high or too low. It is suitable for processes that require uniform gas distribution, such as large-area gas purging and uniform material mixing, thereby improving the consistency of process treatment results.

[0040] Furthermore, such as Figure 2 As shown, the driving component 4 includes a driving motor 41, one end of which is mounted with a driving shaft 42. The end of the driving shaft 42 passes through the fixed shell 31 and is connected and fixed to the rotating shell 32.

[0041] When the drive motor 41 is powered on, it rotates and transmits rotational power to the rotating shell 32 via the drive shaft 42. This causes the rotating shell 32 to rotate inside the fixed shell 31, thereby adjusting the alignment of the air inlet 321 with the nozzle 33. This provides a stable and reliable power source, precisely controls the rotation angle and speed of the rotating shell 32, and thus achieves accurate adjustment of the jet direction, ensuring the stability and accuracy of the adjustment process and meeting the requirements for jet direction adjustment precision under different operating conditions.

[0042] Furthermore, such as Figure 2As shown, an annular sealing groove 312 is provided between the fixed shell 31 and the rotating shell 32. A corrosion-resistant sealing ring is installed in the annular sealing groove 312. The corrosion-resistant sealing ring is made of fluororubber or polytetrafluoroethylene.

[0043] A corrosion-resistant sealing ring is installed in the annular sealing groove 312 between the fixed shell 31 and the rotating shell 32. During the rotation of the rotating shell 32, the sealing ring tightly fits against the fixed shell 31 and the rotating shell 32, preventing gas from leaking out from the gap between them. This ensures the sealing performance of the jet component 3, prevents gas leakage, avoids pressure loss and environmental pollution caused by gas leakage, and the corrosion-resistant sealing ring extends the service life of the sealing structure, improving the reliability and safety of equipment operation.

[0044] Furthermore, such as Figure 1 As shown, a flow regulating valve 5 is installed on the gas pipeline 1.

[0045] The flow regulating valve 5 is installed on the gas supply pipe 1. By adjusting the position of the valve core, the cross-sectional area of ​​the gas flow channel is changed, thereby controlling the gas flow rate. The gas flow rate entering the gas injector can be flexibly adjusted according to different process requirements, achieving precise control of the gas injection volume, meeting diverse production process requirements, and improving the equipment's process adaptability and energy-saving effect.

[0046] Furthermore, the gas supply pipe 1 and the jet component are made of corrosion-resistant materials, such as polyvinylidene fluoride, polypropylene, or stainless steel.

[0047] The gas supply pipe 1 and the jetting component 3 are made of corrosion-resistant materials such as polyvinylidene fluoride, polypropylene, or stainless steel. These materials themselves have good corrosion resistance and can resist the erosion of corrosive gases. This enables the gas ejector to operate stably in harsh environments where corrosive gases are being handled, effectively extending the service life of the equipment, reducing the frequency of repair or replacement due to corrosion damage, and lowering the company's equipment maintenance and operating costs.

[0048] In use, the multi-nozzle gas injector of this invention first starts the air pump 2, which draws in and pressurizes external gas through the lower end of the gas delivery pipe 1, causing the gas to be transported upward along the gas delivery pipe 1. When the gas reaches the top of the gas delivery pipe 1 near the jet component 3, the expansion port 11 increases the cross-sectional area of ​​the gas flow. According to the principles of fluid mechanics, the gas velocity decreases, the pressure distribution becomes more uniform, and turbulence and pressure loss at the connection between the gas delivery pipe 1 and the jet component 3 are reduced, ensuring that the gas enters the jet component 3 smoothly.

[0049] After the gas enters the jet component 3, it waits to be distributed within the fixed housing 31. The drive motor 41 in the drive component 4 is energized and rotates, driving the drive shaft 42 to rotate. The drive shaft 42 is fixedly connected to the rotating housing 32, causing the rotating housing 32 to rotate inside the fixed housing 31. The adjusting air passage 321 on one side of the outer wall of the rotating housing 32 rotates accordingly. When the adjusting air passage 321 aligns with a nozzle 33 at a certain position on the outer wall of the fixed housing 31, the gas flows into the corresponding nozzle 33 through the adjusting air passage 321. During this process, because the nozzles 33 are arranged in a ring at equal intervals on the outer wall of the fixed housing 31, and the adjusting air passage 321 can be aligned with different nozzles 33 by rotating the rotating housing 32, the direction of gas ejection can be flexibly changed. Simultaneously, the corrosion-resistant sealing ring installed in the annular sealing groove 312 between the fixed housing 31 and the rotating housing 32 fits tightly against them, effectively preventing gas leakage from the gap between them and ensuring the sealing performance of the jet component 3.

[0050] The flow regulating valve 5 installed on the gas supply pipe 1 controls the gas flow rate entering the gas injector by adjusting the position of the valve core to change the cross-sectional area of ​​the gas flow channel. Operators can flexibly adjust the flow regulating valve 5 according to different process requirements to achieve precise control of the gas injection volume and meet diverse production process requirements.

[0051] After the above adjustment process, gas is ejected from the nozzle 33, which is connected to the adjustment port 321. Since the nozzle 33 is connected to the fixed housing 31 via a threaded interface 311 and a threaded end, it is easy to disassemble and replace. If the nozzle 33 experiences wear or blockage, maintenance can be performed quickly. Meanwhile, the gas supply pipe 1 and the jetting component 3 are made of corrosion-resistant materials such as polyvinylidene fluoride, polypropylene, or stainless steel, which can resist the erosion of corrosive gases, ensuring stable operation of the gas ejector in harsh environments handling corrosive gases, allowing for stable gas ejection and completion of the jetting operation.

[0052] Finally, it should be noted that the electronic components in the air pump 2, drive motor 41, etc. in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
