Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for oxygen, nitrogen, and hydrogen analyzers, and in particular to a cleaning device for oxygen, nitrogen, and hydrogen analyzers. Background Technology

[0002] Oxygen, nitrogen, and hydrogen analyzers are mainly used to determine the oxygen, nitrogen, and hydrogen content in inorganic materials such as metals, alloys, and ceramics. The oxygen, nitrogen, and hydrogen content in these materials directly affects their properties. Taking steel as an example, high oxygen content reduces its mechanical properties, hydrogen easily leads to hydrogen embrittlement, and nitrogen has a dual effect. Therefore, accurate and rapid determination of the oxygen, nitrogen, and hydrogen content in metals and alloys is crucial. The analysis process requires high-temperature heating, which may generate a large amount of waste material and cause graphitization of the graphite crucibles used to store the materials. The resulting dust can contaminate the equipment. Incomplete cleaning can not only reduce test accuracy but also damage the instrument. Therefore, ensuring accurate and rapid detection is of paramount importance.

[0003] In existing technologies, the diverse internal structures of oxygen, nitrogen, and hydrogen analyzers make it difficult to ensure a tight fit between cleaning tools and the surfaces to be cleaned when cleaning different models of analyzers. This results in low cleaning efficiency and often requires a lot of time and repeated operations, yet still fails to achieve the desired cleaning effect. This seriously affects the normal operating frequency and detection efficiency of the instruments. The analyzers have poor adaptability from compact small analyzers to large and complex professional equipment, and existing cleaning methods are complicated and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of complex operation and poor adaptability of cleaning devices in the existing technology, and to propose a cleaning device for oxygen, nitrogen and hydrogen analyzers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device for an oxygen, nitrogen, and hydrogen analyzer, comprising a fixed cylinder, a small motor fixedly mounted on the top of the fixed cylinder, a rotating rod fixedly connected to the output end of the small motor, a cleaning brush provided at the end of the rotating rod away from the small motor, liquid storage chambers provided on both sides of the small motor, an installation cylinder fixedly connected to the top of the inside of the fixed cylinder, an injector body fixedly connected to both ends of the arc-shaped surface of the installation cylinder, the liquid storage chambers and the injector bodies being connected through a connecting pipe, an inlet being connected through the top of the liquid storage chamber, and a limit rod fixedly connected to the top of the arc-shaped surface of the fixed cylinder.

[0006] Furthermore, the limiting rods are arranged in three groups in a circular pattern on the arc-shaped surface of the fixed cylinder. Each limiting rod includes a support rod, and a groove is provided at the bottom of the support rod. A limiting block is slidably connected inside the groove, thereby improving the stability and adaptability of the cleaning device.

[0007] Furthermore, a fixing ring is fixedly connected to the bottom end of the fixing cylinder, and filter holes are opened on the surface of the fixing cylinder to prevent impurities from entering the injector body and affecting the operation of the rotating rod.

[0008] Furthermore, the rotating rod includes a transmission rod, one end of which is fixedly connected to the output end of a small motor, and the other end of which is fixedly connected to the fixed end of a first electric push rod. The telescopic end of the first electric push rod is fixedly connected to the cleaning brush, thereby improving the working flexibility and cleaning effect of the cleaning brush.

[0009] Furthermore, the cleaning brush includes a connecting post, and a second electric push rod is fixedly connected to both sides of the connecting post. A cleaning scraper is fixedly connected to the telescopic end of the second electric push rod, thereby enhancing the cleaning device's ability to clean stubborn stains.

[0010] Furthermore, the cleaning scraper includes a mounting plate, which is fixedly connected to the telescopic end of the second electric push rod. A buffer spring is fixedly connected to the side of the mounting plate away from the second electric push rod, and a brush is fixedly connected to the end of the buffer spring away from the mounting plate, thereby protecting the instrument surface and improving the cleaning effect.

[0011] Furthermore, the mounting cylinder is connected to the rotating rod, and the surface of the injector body is provided with several nozzles, thereby achieving comprehensive and efficient spraying of cleaning liquid.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a small motor drives the rotating rod and cleaning brush to rotate, eliminating the need for manual cleaning during use. This makes operation convenient and improves efficiency. At the same time, the sprayer body sprays cleaning liquid, achieving a cleaning method that combines brushing and liquid washing, greatly improving the thoroughness of cleaning and increasing convenience.

[0014] 2. In this utility model, by means of adaptive adjustment of the limiting rod, adjustment of the position and force of the cleaning brush and cleaning scraper by the first electric push rod and the second electric push rod, the cleaning device can better adapt to different internal structures and contamination conditions of the oxygen, nitrogen and hydrogen analyzer, thereby improving the adaptability of the cleaning device.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a cleaning device for an oxygen, nitrogen, and hydrogen analyzer, including a fixed cylinder 1, a small motor 2 fixedly installed on the top of the fixed cylinder 1, a rotating rod 21 fixedly connected to the output end of the small motor 2, a cleaning brush 22 provided at the end of the rotating rod 21 away from the small motor 2, liquid storage chambers 3 provided on both sides of the small motor 2, an installation cylinder 4 fixedly connected to the top of the inside of the fixed cylinder 1, an injector body 5 fixedly connected to both ends of the arc-shaped surface of the installation cylinder 4, the liquid storage chamber 3 and the injector body 5 are connected through a connecting pipe 31, an inlet 32 ​​is connected through the top of the liquid storage chamber 3, and a limit rod 6 is fixedly connected to the top of the arc-shaped surface of the fixed cylinder 1.

[0023] The specific configuration and function of the rotating rod 21, cleaning brush 22 and limit rod 6 will be explained below.

[0024] In this embodiment: there are three sets of limiting rods 6 distributed in a circle on the arc-shaped surface of the fixed cylinder 1. The limiting rods 6 include support rods 61, and the bottom of the support rods 61 is provided with a sliding groove 62. The sliding groove 62 is slidably connected to a limiting block 63.

[0025] The aforementioned components achieve the following effect: when the cleaning device is placed inside the oxygen, nitrogen, and hydrogen analyzer to be cleaned, the limiting block 63 can slide freely along the slide groove 62. Due to the complex internal structure of the oxygen, nitrogen, and hydrogen analyzer, the spatial shape and size vary at different locations, and the three sets of circumferentially distributed limiting rods 6 can adaptively adjust from different directions. When encountering protrusions or depressions inside the instrument, the limiting block 63 will move within the slide groove 62 according to the actual situation, thereby ensuring that the fixed cylinder 1 can be stably placed in the predetermined cleaning area, preventing the cleaning device from shaking or shifting during the cleaning process, and greatly improving the stability and adaptability of the cleaning device in complex environments.

[0026] Specifically, a fixing ring 11 is fixedly connected to the bottom end of the fixing cylinder 1, and filter holes 12 are opened on the surface of the fixing cylinder 1.

[0027] The effects achieved by the above components are: the filter hole 12 prevents impurities such as waste and dust from entering the injector body 5 and prevents them from affecting the normal operation of the rotating rod 21.

[0028] In this embodiment: the rotating rod 21 includes a transmission rod 211, one end of which is fixedly connected to the output end of the small motor 2, and the other end of which is fixedly connected to the fixed end of the first electric push rod 212. The telescopic end of the first electric push rod 212 is fixedly connected to the cleaning brush 22.

[0029] The effect achieved by the above-mentioned components is that their output shaft drives the transmission rod 211 to rotate at high speed. At this time, the first electric push rod 212 can be extended and retracted according to the actual cleaning needs. The adjustable structural design greatly improves the working flexibility of the cleaning brush 22, enabling it to adapt to surfaces of different positions and shapes to be cleaned.

[0030] In this embodiment: the cleaning brush 22 includes a connecting post 221, and a second electric push rod 222 is fixedly connected to both sides of the connecting post 221. A cleaning scraper 223 is fixedly connected to the telescopic end of the second electric push rod 222.

[0031] The aforementioned components achieve the following effect: During the cleaning process, the bristles of the cleaning brush 22 can perform routine cleaning when encountering ordinary stains. Once stubborn stains are encountered, the second electric actuator 222 comes into play, greatly enhancing the cleaning device's ability to clean stubborn stains and ensuring that stubborn stains inside the oxygen, nitrogen, and hydrogen analyzer can be completely removed.

[0032] Specifically, the cleaning scraper 223 includes a mounting plate 2231, which is fixedly connected to the telescopic end of the second electric push rod 222. A buffer spring 2232 is fixedly connected to the side surface of the mounting plate 2231 away from the second electric push rod 222, and a brush 2233 is fixedly connected to the end of the buffer spring 2232 away from the mounting plate 2231.

[0033] The aforementioned components achieve the following effect: when the cleaning scraper 223 contacts the surface of the oxygen, nitrogen, and hydrogen analyzer under the push of the second electric actuator 222, the buffer spring 2232 plays a crucial buffering role. It effectively prevents damage to the instrument surface caused by rigid contact with the cleaning scraper 223, protecting the instrument's precision components. Simultaneously, under the action of the buffer spring 2232, the brush 2233 can closely adhere to the surface to be cleaned, significantly improving the cleaning effect.

[0034] Specifically, the mounting cylinder 4 is connected to the rotating rod 21, and the surface of the injector body 5 is provided with several nozzles.

[0035] The effect achieved by the above components is to expand the spray range of the cleaning fluid, enabling the cleaning fluid to cover every corner inside the oxygen, nitrogen, and hydrogen analyzer, thus achieving a comprehensive and efficient spraying effect of the cleaning fluid.

[0036] Working principle: When using this cleaning device, first inject an appropriate amount of cleaning solution into the storage chamber 3 through the inlet 32. Then, place the cleaning device inside the oxygen, nitrogen, and hydrogen analyzer to the part that needs to be cleaned. The limiting blocks 63 on the three sets of limiting rods 6 will slide adaptively in the slide groove 62 according to the internal structure of the instrument, and cooperate with the fixing ring 11 to make the fixing cylinder 1 stably placed.

[0037] Next, the small motor 2 is started, which drives the transmission rod 211 to rotate. The transmission rod 211 drives the cleaning brush 22 to rotate via the first electric push rod 212. At the same time, the cleaning fluid in the liquid storage chamber 3 enters the sprayer body 5 through the connecting pipe 31 and is evenly sprayed onto the area to be cleaned by the nozzle on the surface of the sprayer body 5.

[0038] During the cleaning process, the first electric actuator 212 adjusts the position of the cleaning brush 22 according to the position and shape of the surface to be cleaned. When encountering stubborn stains, the second electric actuator 222 extends, driving the cleaning scraper 223 to remove the stains. The buffer spring 2232 and the brush 2233 further clean the stains while protecting the instrument surface. Waste liquid and impurities generated during the cleaning process are discharged through the filter 12, thus completing an efficient and comprehensive cleaning of the interior of the oxygen, nitrogen, and hydrogen analyzer.
