Description

Technical Field

[0001] This utility model relates to the field of nitrogen filling equipment technology, and in particular to a portable digital display intelligent nitrogen filling machine. Background Technology

[0002] Nitrogen filling machines play a vital role in industrial production and many other fields. Their applications are wide-ranging, covering numerous industrial and mining enterprises and units such as steel mills, gas spring manufacturers, power plants, machinery and equipment factories, and pipeline companies. They can be used to fill accumulators, gas springs, high-pressure vessels, and other equipment requiring nitrogen.

[0003] However, existing nitrogen filling machines have shortcomings in practical use. The pipes of the nitrogen filling machine, as the key channels in the nitrogen filling process, are highly susceptible to absorbing dust and impurities from the surrounding environment. In industrial production environments, dust particles are abundant. Over time, a large amount of dust and impurities accumulate on the outer wall of the pipes, gradually forming a layer of dirt. This not only affects the cleanliness of the nitrogen filling machine's appearance but also increases the frictional resistance between the pipes when storing them. In particular, some sharp impurities may scratch the outer wall of the pipes, causing surface wear, which in turn affects the performance and service life of the pipes.

[0004] Currently, most nitrogen filling machines on the market lack effective prevention and cleaning measures for the adsorption of dust and impurities on the outer walls of the pipelines. Some machines rely solely on regular manual cleaning, but this method is not only labor-intensive and resource-intensive, but also makes it difficult to guarantee the cleaning frequency. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the aforementioned portable digital display intelligent nitrogen filling machine, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable digital display intelligent nitrogen filling machine, comprising:

[0008] The main box has an auxiliary box on one side;

[0009] An air reel is installed on the inner wall of one side of the main box, and the end of the pipe wound on it is provided with a conversion joint, which extends into the auxiliary box.

[0010] The traction wheel assembly includes two pressure rollers distributed on both sides of the pipeline, and the distance between the two pressure rollers is smaller than the diameter of the pipeline;

[0011] Two mounting brackets are symmetrically distributed on the upper and lower sides of the pipeline. A semi-circular wiping pad is provided on the side of the mounting bracket closest to the pipeline, and the concave surfaces of the two semi-circular wiping pads form a wiping area for the outer wall of the pipeline.

[0012] In a preferred embodiment of the portable digital display intelligent nitrogen filling machine of this utility model, the gap between the concave surface of the semi-circular wiping pad and the pipe wall gradually decreases along the pipe receiving direction until it contacts the pipe wall.

[0013] In a preferred embodiment of the portable digital display intelligent nitrogen filling machine of this utility model, the mounting frame is located between the air path reel and the pressure roller.

[0014] In a preferred embodiment of the portable digital display intelligent nitrogen filling machine of this utility model, a plurality of friction-enhancing pads are arranged around the pressure roller.

[0015] As a preferred embodiment of the portable digital display intelligent nitrogen filling machine of this utility model, the main box is equipped with a nitrogen cylinder, the nitrogen cylinder is connected to a delivery pipe through a cylinder valve, the end of the delivery pipe is connected to a rotary joint on the gas reel, and a pressure reducing valve, a pressure regulating valve, a solenoid valve, an electronic barometer and an electromagnetic flow meter are installed on the delivery pipe in sequence.

[0016] In a preferred embodiment of the portable digital display intelligent nitrogen filling machine of this utility model, a display screen and a processor are installed on the lid of the main box.

[0017] The beneficial effects of this utility model are:

[0018] 1. The combination of the traction wheel set and the air reel facilitates the storage of pipelines, resulting in a more orderly pipeline distribution and effectively preventing tangling and bending. Simultaneously, the pipeline is slightly deformed as it passes through the pressure rollers, causing the outer wall of the pipeline to contract and allowing dust and impurities to detach easily. The two semi-circular wiping pads further remove dust and impurities from the pipeline walls, effectively preventing surface dust and impurities from causing pressure and wear on the pipeline's outer wall after storage, thus significantly extending the pipeline's service life.

[0019] 2. By using pressure reducing valve, pressure regulating valve, solenoid valve, electronic barometer and electromagnetic flowmeter installed on the nitrogen cylinder delivery pipe, relevant data can be displayed on the screen during the nitrogen filling process, which facilitates the operation of the operator and improves the nitrogen filling efficiency.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0031] Reference Figures 1-4 As one embodiment of this utility model, a portable digital display intelligent nitrogen filling machine is provided, which includes:

[0032] The main box 1 has an auxiliary box 11 on one side, which is used to store and support the main components and is also convenient to carry.

[0033] The air reel 2 is installed on the inner wall of one side of the main box 1. The end of the pipe 21 wound on it is provided with a conversion connector 22, and the conversion connector 22 extends into the auxiliary box 11 to facilitate the storage and connection of the pipe 21. In addition, the air reel 2 has a spring (not shown in the text) inside, which can facilitate the active storage of the pipe 21.

[0034] The traction wheel assembly includes two pressure rollers 3 distributed on both sides of the pipe 21. Several friction-enhancing pads 31 are arranged around the pressure rollers 3 to prevent the pipe 21 from slipping on the pressure rollers 3. The distance between the two pressure rollers 3 is smaller than the diameter of the pipe 21. When the pipe 21 passes through the pressure rollers 3, it will be squeezed to slight deformation, causing the outer wall of the pipe 21 to shrink, which facilitates the removal of dust and impurities.

[0035] Two mounting brackets 4 are detachably mounted on the traction wheel assembly and can be removed and replaced after a period of use. The mounting brackets 4 are located between the air reel 2 and the traction wheel assembly and are symmetrically distributed on the upper and lower sides of the pipe 21. A semi-circular wiping pad 41 is provided on the side of the mounting bracket 4 closest to the pipe 21. The concave surfaces of the two semi-circular wiping pads 41 form a wiping area for the outer wall of the pipe 21. When the pipe 21 passes through the semi-circular wiping pads 41, impurities on its surface will be scraped off, preventing dust and impurities on the surface of the pipe 21 from causing compression and wear on the outer wall of the pipe 21 after it is stored, thereby effectively improving the service life of the pipe 21.

[0036] The gap between the concave surface of the semi-circular wiping pad 41 and the wall of the pipe 21 gradually decreases along the receiving direction of the pipe 21 until it contacts the wall of the pipe 21. When the outer wall of the pipe 21 is smooth, its contact area with the concave surface of the semi-circular wiping pad 41 is small. When there is dust or impurities on its outer wall, the impurities will be scraped off in the concave surface of the semi-circular wiping pad 41. At the same time, the concave surface has space to temporarily collect impurities and dust, preventing them from entering the main box 1. The impurities can be removed by periodically replacing the mounting bracket 4.

[0037] like Figure 1 and Figure 5As shown, the main chamber 1 is equipped with a nitrogen cylinder 5. The nitrogen cylinder 5 is connected to a delivery pipe 51 through a cylinder valve. The end of the delivery pipe 51 is connected to a rotary joint 23 on the gas reel 2. The delivery pipe 51 is equipped with a pressure reducing valve 510 (used to reduce the nitrogen pressure to a safe range), a pressure regulating valve 511 (to accurately regulate the nitrogen output pressure), a solenoid valve 512 (to control the nitrogen flow and is electrically connected to the processor 7), an electronic barometer 513 (to monitor the gas pressure in real time and is electrically connected to the processor 7), and an electromagnetic flowmeter 514 (to accurately measure the nitrogen flow and is electrically connected to the processor 7). The main chamber 1 is equipped with a display screen 6 (to display real-time data and the operation interface and is electrically connected to the processor 7) and a processor 7 (to control the coordinated operation of various components, process sensor data, and output to the display screen 6). This achieves precise control and intelligent monitoring of nitrogen delivery, improving operational convenience and safety.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
