A mobile nitrogen generator

Abstract

This utility model discloses a mobile nitrogen generator, relating to the field of nitrogen generators. The utility model includes a nitrogen generator body, with a cover shell covering the outer side of the body. Lifting mechanisms are provided on both sides of the cover shell to raise or lower it, thus controlling whether the nitrogen generator body is covered. Through the cover shell and lifting mechanisms, when the equipment needs to be stored or transported, a multi-stage electric cylinder retracts, pulling the cover shell down via a sprocket and chain drive. This causes the cover shell to descend vertically along four sets of longitudinal slide rails to a closed state, completely covering the nitrogen generator body. A tension linkage is formed under the drive of the multi-stage electric cylinder. Mining rollers at the bottom of the base plate provide movement support during transport, while the rigid fit between the slide rails and the slider further absorbs vibration and impact, reducing the risk of damage to internal components. This mechanical linkage design dynamically switches between protective and working states, balancing sealing and operational efficiency.

Description

Technical Field

[0001] This utility model relates to the field of nitrogen generators, specifically a mobile nitrogen generator. Background Technology

[0002] The mobile nitrogen generator is a portable gas separation device based on pressure swing adsorption technology. It selectively adsorbs oxygen through carbon molecular sieves to produce nitrogen with a purity of 95%~99.9995%, with a production capacity ranging from 5 to 3000 Nm³ / h. Its skid-mounted or vehicle-mounted design is suitable for oil fields, chemical plants, food processing plants, and other scenarios. It supports operation in environments without power supply and features explosion-proof, low-energy consumption, and intelligent control characteristics. Its core applications are in oil extraction, food preservation, electronics manufacturing, and emergency rescue.

[0003] Existing nitrogen generators have a problem during use: they are usually open-type units. When not in use, such as during storage or transportation, the open design allows the nitrogen generator to be affected by the external environment, causing corrosion from dust, moisture, oil, etc. This reduces the ease of cleaning and shortens the lifespan of the nitrogen generator. Therefore, the inventors urgently need to design a shielding mechanism that can effectively block external dust and moisture to improve the protection of the nitrogen generator. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a mobile nitrogen generator to solve the technical problem of protecting mobile nitrogen generators from dust and moisture corrosion during storage and transportation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile nitrogen generator, comprising a nitrogen generator body, wherein a cover shell is provided on the outer side of the nitrogen generator body, and lifting mechanisms are provided on both sides of the cover shell to lift the cover shell.

[0006] The lifting mechanism includes four sets of slide rails. The cover sleeve is slidably installed on the slide rails via a slider. A mounting bracket is provided on one side of the slide rail. A multi-stage electric cylinder is installed on the mounting bracket. A sprocket is rotatably installed on the telescopic end of the multi-stage electric cylinder. A chain is driven on the outer side of the sprocket.

[0007] By adopting the above technical solution, dynamic protection and convenient operation of the nitrogen generator body are achieved. When the equipment is not in operation, the multi-stage electric cylinder in the lifting mechanism drives the sprocket to retract or extend the chain, so that the cover shell can be raised and lowered smoothly along the four sets of slide rails, completely covering the nitrogen generator body and effectively isolating it from external dust, water vapor and oil corrosion.

[0008] Furthermore, fixing ears are provided on both sides of the lower part of the cover shell, one end of the chain is fixedly connected to the fixing ears, and the other end of the chain is fixedly connected to the mounting bracket.

[0009] By adopting the above technical solution, the coordination between the cover and the lifting mechanism is enhanced. By fixing both ends of the chain to the fixing ears and the mounting bracket respectively, it is ensured that the chain is always taut during the lifting process, avoiding shaking or jamming of the cover due to chain slack.

[0010] Furthermore, the multi-stage electric cylinder is electrically connected to an external power source via a controller, and the maximum extension and retraction of the multi-stage electric cylinder can drive the cover shell to eliminate the need to cover the main body of the nitrogen generator.

[0011] By adopting the above technical solution, the automatic control of the lifting and lowering of the cover shell is realized. The operator can open or close the cover shell with one button through the controller, which significantly improves the operating efficiency and reduces the risk of manual intervention.

[0012] Furthermore, the slide rails are arranged longitudinally to limit the longitudinal position movement of the cover shell, and the four sets of slide rails are distributed at the four corners of the cover shell.

[0013] By adopting the above technical solution, a clear motion guide is provided for the cover shell, effectively limiting its lateral displacement and ensuring the vertical accuracy of the lifting process. The four sets of slide rails are distributed at the four corners of the cover shell to form a symmetrical support structure, which evenly distributes the load and reduces the risk of deformation caused by excessive force at a single point.

[0014] Furthermore, the cover shell is made of aluminum alloy, and some panels can be made of transparent acrylic sheet structure, and ventilation holes can be opened according to the usage environment.

[0015] By adopting the above technical solutions, while ensuring lightweight design, it also has excellent corrosion resistance and can withstand the erosion of harsh environments such as humidity and salt spray for a long time. The partial panel design of the transparent acrylic plate structure allows the operator to observe the operating status of the nitrogen generator without opening the cover, thus improving the convenience of monitoring.

[0016] Furthermore, the main body of the nitrogen generator includes a filter, a water cooler, an activated carbon tank, a gas storage tank, a main unit, an electrical control box, and a silencer.

[0017] By adopting the above technical solutions, the modular component design of the nitrogen generator achieves functional zoning and efficient collaboration. The filter pre-treats particulate impurities in the air, the activated carbon canister further adsorbs oil mist and harmful gases, and the water cooler cools the compressed nitrogen to ensure that the gas entering the storage tank meets the process requirements.

[0018] Furthermore, the bottom of the nitrogen generator body is supported by a base plate, and mining rollers are installed under the base plate. A drive component is connected to one side of the base plate via a connecting lug pin.

[0019] By adopting the above technical solution, the combination of the base plate and the mining rollers takes into account both the mobility and stability of the equipment. The high-strength material of the mining rollers reduces the risk of equipment damage caused by bumps during transportation.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention utilizes a cover and lifting mechanism. When the equipment needs to be stored or transported, a multi-stage electric cylinder retracts, pulling the cover down via a sprocket and chain drive. This causes the cover to descend vertically along four sets of longitudinal slide rails to a closed state, completely covering the nitrogen generator body. Driven by the multi-stage electric cylinder, a tension linkage is formed, ensuring the synchronous lifting and lowering of the cover and preventing deformation caused by uneven force on one side. Mining rollers at the bottom of the base plate provide support during transport, while the rigid fit between the slide rails and the slider further absorbs vibration and impact, reducing the risk of damage to internal components. This mechanical linkage design dynamically switches between protective and working states, balancing sealing and operational efficiency. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment: a mobile nitrogen generator, such as... Figure 1-4As shown, it includes a nitrogen generator body 1, and a cover shell 2 is provided on the outside of the nitrogen generator body 1. Lifting mechanisms 3 are provided on both sides of the cover shell 2 to lift the cover shell 2.

[0029] The lifting mechanism 3 includes four sets of slide rails 301. The cover shell 2 is slidably installed on the slide rails 301 via a slider. A mounting bracket 306 is provided on one side of the slide rail 301. A multi-stage electric cylinder 302 is installed on the mounting bracket 306. A sprocket 303 is rotatably installed on the extension end of the multi-stage electric cylinder 302. A chain 305 is driven on the outer side of the sprocket 303, realizing dynamic protection and convenient operation of the nitrogen generator body 1. When the equipment is not in operation, the multi-stage electric cylinder 302 in the lifting mechanism 3 drives the sprocket 303 to drive the chain 305 to retract or extend, so that the cover shell 2 rises and falls smoothly along the four sets of slide rails 301, completely covering the nitrogen generator body 1, effectively isolating it from external dust, water vapor and oil corrosion. At the same time, the cooperation between the slide rails 301 and the slider ensures that the cover shell 2 maintains a vertical movement trajectory during the lifting process, avoiding sealing failure or mechanical wear caused by deviation. The slide rails 301 distributed at the four corners further improve the stability of the cover shell 2, enabling it to operate reliably in complex environments.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The cover housing 2 has fixed ears 304 on both sides of the lower part. One end of the chain 305 is fixedly connected to the fixed ear 304, and the other end of the chain 305 is fixedly connected to the mounting bracket 306. This enhances the coordination between the cover housing 2 and the lifting mechanism 3. By fixing both ends of the chain 305 to the fixed ear 304 and the mounting bracket 306 respectively, it is ensured that the chain 305 is always taut during the lifting process, avoiding the cover housing 2 from shaking or getting stuck due to chain slack. At the same time, the fixed ears 304 are located on both sides of the lower part of the cover housing 2, which makes the tension distribution more uniform, reduces the damage to the structure caused by local stress concentration, and facilitates later maintenance. For example, the replacement or adjustment of the chain 305 can be quickly completed through the fixed ear 304 without disassembling other components.

[0031] See Figure 1 , Figure 2 , Figure 3The multi-stage electric cylinder 302 is electrically connected to an external power source via a controller. The maximum extension and retraction of the multi-stage electric cylinder 302 can drive the cover shell 2 to remove the cover from the nitrogen generator body 1, realizing automated control of the lifting and lowering of the cover shell 2. The operator can open or close the cover shell 2 with one button via the controller, which significantly improves operating efficiency and reduces the risk of manual intervention. At the same time, the maximum extension and retraction of the multi-stage electric cylinder 302 is precisely designed to ensure that the cover shell 2 is completely removed from the nitrogen generator body 1, so that the main unit 105, filter 101 and other core components are fully exposed, ensuring the normal operation of the nitrogen generation process.

[0032] See Figure 1 , Figure 2 , Figure 3 The slide rails 301 are arranged longitudinally to limit the longitudinal position movement of the cover shell 2. The four sets of slide rails 301 are distributed at the four corners of the cover shell 2, providing clear motion guidance for the cover shell 2, effectively limiting its lateral offset, and ensuring the vertical accuracy of the lifting process. The four sets of slide rails 301 distributed at the four corners of the cover shell 2 form a symmetrical support structure, evenly distribute the load and reduce the risk of deformation caused by excessive force at a single point. At the same time, the longitudinal layout of the slide rails 301 optimizes the overall space utilization of the equipment and avoids affecting the compact layout of the nitrogen generator body 1 due to excessive space occupied by the lateral slide rails.

[0033] See Figure 1 , Figure 2 , Figure 3 The cover shell 2 is made of aluminum alloy, and some panels can be made of transparent acrylic sheet structure. Ventilation holes can be opened according to the usage environment. While ensuring lightweight, it has excellent corrosion resistance and can resist the erosion of harsh environments such as humidity and salt spray for a long time. The partial panel design of the transparent acrylic sheet structure allows the operator to observe the operating status of the nitrogen generator body 1 without opening the cover shell 2, improving the convenience of monitoring. At the same time, the adaptable design of the ventilation holes takes into account the protection and heat dissipation requirements: in the closed state, the coordinated layout of the transparent acrylic sheet and the ventilation holes also optimizes the air pressure balance inside and outside the equipment, preventing negative pressure or condensation problems caused by excessive sealing.

[0034] See Figure 4The nitrogen generator main body 1 includes a filter 101, a water cooler 102, an activated carbon canister 103, a gas storage tank 104, a main unit 105, an electrical control box 106, and a silencer. The modular component design of the nitrogen generator main body 1 realizes functional zoning and efficient collaboration. The filter 101 pre-treats particulate impurities in the air, the activated carbon canister 103 further adsorbs oil mist and harmful gases, and the water cooler 102 cools the compressed nitrogen gas to ensure that the gas entering the gas storage tank 104 meets the process requirements. At the same time, the centralized control function of the electrical control box 106 simplifies the operation process. Users can adjust the operating parameters of the main unit 105 through a unified interface, and the silencer significantly reduces noise pollution when the equipment is working.

[0035] See Figure 1 , Figure 2 , Figure 4 The nitrogen generator body 1 is supported by a base plate 4, and mining rollers 5 are installed under the base plate 4. A drive component is connected to one side of the base plate 4 via a connecting lug 6 and a pin. The combination of the base plate 4 and the mining rollers 5 takes into account both the mobility and stability of the equipment. The high-strength material of the mining rollers 5 reduces the risk of equipment damage caused by bumps during transportation. At the same time, the drive component is connected to the base plate 4 via a connecting lug 6 and a pin, allowing users to quickly install or remove the traction device, improving the efficiency of equipment deployment. The planar support design of the base plate 4 distributes the weight of the nitrogen generator body 1, avoiding local overload that could cause wear to the mining rollers 5.

[0036] The implementation principle of this embodiment is as follows: When the mobile nitrogen generator is in working condition, the multi-stage electric cylinder 302 in the lifting mechanism 3 is activated by the controller, which drives the sprocket 303 to extend the chain 305, so that the cover shell 2 slides upward along the four sets of longitudinal slide rails 301, completely exposing the main body 1 and internal components of the nitrogen generator. At this time, the electrical control box 106 controls the host 105 to start the nitrogen generation process. Air adsorbs impurities through the activated carbon canister 103, and nitrogen is cooled by the water cooler 102 and stored in the gas storage tank 104.

[0037] When the equipment needs to be stored or transported, the multi-stage electric cylinder 302 retracts in the reverse direction. At this time, the cover shell 2 closes along the slide rail 301. The aluminum alloy cover shell 2 completely covers the nitrogen generator body 1. Its ventilation holes and transparent acrylic plate area can balance the internal and external air pressure in the closed state and are easy to observe. The mining rollers 5 at the bottom of the base plate 4 are moved by the drive component. During the lifting process, the slide rail 301 and the slider cooperate to ensure that the cover shell 2 moves vertically without deviation. The connection between the fixed ear 304 and the chain 305 further ensures the synchronization of lifting. The dynamic switching of protection and function is realized through mechanical linkage, effectively isolating external dust and moisture.
