Description

Technical Field

[0001] This utility model relates to the field of industrial gas sampling technology, and in particular to a self-cooling industrial gas sampler. Background Technology

[0002] With the development of modern industry, especially in chemical and metallurgical industries, the demand for real-time monitoring of various gas components in production processes is increasing. Existing gas sampling devices are mostly used in low-temperature environments; when exposed to high temperatures, sampling efficiency decreases, and even sample distortion may occur. Therefore, developing efficient gas sampling devices suitable for high-temperature environments has become one of the current research hotspots in the industry.

[0003] A search revealed Chinese Patent Publication No. CN212110821U, which discloses a sampler for industrial waste gas detection, belonging to the field of industrial waste gas detection and sampling technology. It primarily addresses the problems of low accuracy in traditional sampling methods, the influence of residual gas in the collection bottle on subsequent test results, and the presence of water vapor in the detected waste gas. The sampler includes a gas collection bottle, a light emitter, a light sensor, and a microcontroller. Light emitted by the light emitter passes through the waste gas in the collection bottle, is scattered, and is received by the light sensor. It also includes a cabinet with a door, which is mounted on a support frame. An air inlet pipe extending to one side of the cabinet is also provided. This invention is mainly used for sampling and detecting industrial waste gas, and the light scattering detection method is more scientific and accurate.

[0004] Existing gas samplers generally lack effective cooling mechanisms. High-temperature gases may not only cause thermal damage to the internal components of the sampler, but also more easily lead to the evaporation, oxidation, or decomposition of volatile components in the gas, thereby causing changes in the component ratio, resulting in sample distortion and seriously affecting the accuracy and comparability of subsequent analytical data. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-cooling industrial gas sampler, which aims to improve the problem that traditional samplers are difficult to cool down the gas, which can easily cause sample distortion due to high-temperature gas and affect the accuracy of analytical data.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A self-cooled industrial gas sampler includes a frame, a fan fixedly connected inside the frame, ventilation holes inside the frame, a cooling pipe fixedly connected inside the frame, a cooling fin fixedly connected to the outer wall of the cooling pipe, heat dissipation fins fixedly connected to the outer wall of the cooling fin, a gas storage cylinder disposed on the outer wall of the cooling pipe, the lower surface of the gas storage cylinder fixedly connected to the inner wall of the frame, a pressure relief valve disposed inside the gas storage cylinder, and a control component disposed on the outer wall of the frame.

[0008] The above technical solution involves: the collected gas being transported inside the cooling pipe; cooling coils cooling the cooling pipe, which in turn cools the gas; the cooling coils also quickly remove the heat generated by the cooling pipe; and the heat is then expelled to the outside through a fan and ventilation holes, improving heat dissipation capacity. Finally, the collected gas is cooled through the cooling pipe and then transported to the inside of the gas storage cylinder to complete the cooling and collection process, improving data accuracy. A pressure relief valve prevents the gas storage cylinder from overfilling and potentially exploding.

[0009] As a further description of the above technical solution:

[0010] The control assembly includes a controller, the outer wall of which is fixedly connected to the outer wall of the frame. A pressure detector is provided on the upper surface of the gas storage cylinder, and a temperature detector is fixedly connected to the outer wall of the cooling pipe.

[0011] The above technical solution allows the controller to control the start and stop of the data acquisition unit, and at the same time, the controller can view the temperature and pressure parameters of the device in real time based on the detection data from the pressure and temperature detectors.

[0012] As a further description of the above technical solution:

[0013] A filter frame is fixedly connected to the outer wall of the cooling pipe, and the outer wall of the filter frame is fixedly connected to the outer wall of the frame.

[0014] The above technical solution allows for the filtration of the gas being collected between the cooling pipes using a filter frame, effectively removing particulate matter and other impurities.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the filter frame is slidably connected to a sliding column, and one end of the sliding column is fixedly connected to a push button.

[0017] Through the above technical solution, the filter frame can provide sliding support for the sliding column, and when the push button is pushed, it will also cause the sliding column to slide.

[0018] As a further description of the above technical solution:

[0019] The other end of the sliding column is fixedly connected to a locking block, and the outer wall of the locking block is fixedly connected to a spring, which is in turn fixedly connected to the inner wall of the filter frame.

[0020] Through the above technical solution: the sliding column will cause the locking block to slide, which will then compress the spring. The spring can push the locking block to lock onto the inner wall of the filter plate, thus fixing it in place.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the card block is provided with a filter plate, the outer wall of the filter plate is set on the inner wall of the filter frame, and a handle is fixedly connected to the upper surface of the filter plate.

[0023] With the above technical solution, when the locking block is pushed out of the inner wall of the filter plate, the limiting position on the filter plate can be released, allowing the filter plate to slide out of the filter frame by pulling the handle, making it convenient for replacement.

[0024] As a further description of the above technical solution:

[0025] A push plate is provided on the upper surface of the filter plate, and a connecting column is fixedly connected to the upper surface of the push plate.

[0026] Through the above technical solution: the push plate can limit the position of the filter plate, and the connecting column can support the push plate.

[0027] As a further description of the above technical solution:

[0028] A limiting ring is fixedly connected to the bottom end of the connecting column, and a second spring is fixedly connected to the upper surface of the limiting ring. The top end of the second spring is fixedly connected to the inner wall of the filter frame.

[0029] The above technical solution allows the spring force of spring two to push the limiting ring downward, which in turn drives the connecting column and push plate to slide downward, so that the push plate continuously applies downward pressure to the filter plate, making the filter plate fit tightly against the filter frame.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the cooperation between the frame, fan, ventilation holes, cooling pipe, cooling plate, heat dissipation fins, gas storage bottle and pressure relief valve enables the pre-cooling of the collected gas, which can avoid sample distortion caused by high temperature and improve the accuracy of subsequent detection data.

[0032] 2. In this utility model, through the mutual cooperation between the filter frame, sliding column, push button, locking block, spring one, filter plate, handle, push plate, connecting column, limiting ring and spring two, the staff can quickly replace the filter plate, facilitate regular cleaning and maintenance of the filter plate, improve maintenance efficiency, and at the same time make the filter plate and filter frame fit tightly together, improving airtightness.

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Reference Figure 1 and Figure 2An embodiment of this utility model provides a self-cooling industrial gas sampler, comprising a frame 1, a fan 2 fixedly connected inside the frame 1, a ventilation hole 3 opened inside the frame 1, a cooling pipe 4 fixedly connected inside the frame 1, a cooling plate 5 fixedly connected to the outer wall of the cooling pipe 4, heat dissipation fins 6 fixedly connected to the outer wall of the cooling plate 5, a gas storage cylinder 7 provided on the outer wall of the cooling pipe 4, the lower surface of the gas storage cylinder 7 fixedly connected to the inner wall of the frame 1, a pressure relief valve 8 provided inside the gas storage cylinder 7, and a control component 9 provided on the outer wall of the frame 1.

[0041] Specifically, frame 1 provides fixed support for fan 2. Fan 2 delivers air into frame 1, and then the vents 3 transport the hot air to the outside of frame 1, achieving air cooling. Meanwhile, cooling pipe 4 provides fixed support for cooling element 5. When cooling pipe 4 collects air, cooling element 5 cools it, delivering the cold air into cooling pipe 4 to lower the temperature of the collected gas. While one side of cooling element 5 is cooling, the other side generates heat. Heat dissipation fins 6 quickly remove the heat from cooling element 5, and fan 2 expels the heat absorbed by heat dissipation fins 6 from the device, achieving heat dissipation. The gas cooled by cooling element 5 then enters the gas storage cylinder 7 through cooling pipe 4 for storage. The pressure relief valve 8 prevents the gas storage cylinder 7 from overfilling and exploding due to excessive pressure. By pre-cooling the collected gas, high temperatures can prevent sample distortion and improve the accuracy of subsequent testing.

[0042] Reference Figure 1 and Figure 2 The control component 9 includes a controller 901, the outer wall of which is fixedly connected to the outer wall of the frame 1, a pressure detector 902 is provided on the upper surface of the gas storage cylinder 7, and a temperature detector 903 is fixedly connected to the outer wall of the cooling pipe 4.

[0043] Specifically, frame 1 provides fixed support for controller 901, gas cylinder 7 provides fixed support for pressure detector 902, and cooling pipe 4 provides fixed support for temperature detector 903. The controller 901 can turn the acquisition device on or off, and the pressure detector 902 and temperature detector 903 can detect the gas temperature and the pressure inside gas cylinder 7. These parameters can then be displayed and viewed through the controller 901.

[0044] Reference Figure 3A filter frame 10 is fixedly connected to the outer wall of the cooling pipe 4, and the outer wall of the filter frame 10 is fixedly connected to the outer wall of the frame 1; a sliding column 11 is slidably connected to the inner wall of the filter frame 10, and a push button 12 is fixedly connected to one end of the sliding column 11; a locking block 13 is fixedly connected to the other end of the sliding column 11, and a spring 14 is fixedly connected to the outer wall of the locking block 13, and the outer wall of the spring 14 is fixedly connected to the inner wall of the filter frame 10; a filter plate 15 is provided on the outer wall of the locking block 13, and the outer wall of the filter plate 15 is provided on the inner wall of the filter frame 10; a handle 16 is fixedly connected to the upper surface of the filter plate 15.

[0045] Specifically, the filter frame 10 can pre-filter the gas collected by the cooling pipe 4, removing particulate matter and other impurities from the gas. Simultaneously, the filter frame 10 supports the sliding column 11, ensuring its stable sliding. The sliding column 11, in turn, provides fixed support for the push button 12. When the push button 12 is pulled, it causes the sliding column 11 to slide, which in turn causes the locking block 13 to slide. When the locking block 13 slides out of the inner wall of the filter plate 15, it releases the filter plate 15. The limit switch allows the operator to pull the handle 16 to pull the filter plate 15 out of the inner wall of the filter frame 10, achieving a quick disassembly. When installation is required, first place the filter plate 15 into the inner wall of the filter frame 10, and then push the locking block 13 to slide through the elastic force of the spring 14, so that the locking block 13 slides into the inner wall of the filter plate 15, achieving a quick fixation. By quickly disassembling and installing the filter plate 15, the operator can quickly replace the filter plate 15, which facilitates regular cleaning and maintenance of the filter plate 15 and improves maintenance efficiency.

[0046] Reference Figure 4 A push plate 17 is provided on the upper surface of the filter plate 15, and a connecting column 18 is fixedly connected to the upper surface of the push plate 17; a limit ring 19 is fixedly connected to the bottom end of the connecting column 18, and a spring 20 is fixedly connected to the upper surface of the limit ring 19; the top end of the spring 20 is fixedly connected to the inner wall of the filter frame 10.

[0047] Specifically, when it is necessary to disassemble the filter plate 15, first pull the push plate 17 upward and then rotate it so that the push plate 17 leaves the upper surface of the filter plate 15, thereby releasing the limit of the push plate 17 on the filter plate 15. When it is necessary to limit the filter plate 15, rotate the push plate 17 to the upper surface of the filter plate 15, and then push the limiting ring 19 downward through the elastic force of the second spring 20, thereby driving the connecting column 18 and the push plate 17 to slide upward, so that the push plate 17 always provides downward pressing force on the filter plate 15, ensuring that the filter plate 15 can fit tightly against the inner wall of the cavity of the filter frame 10, improving airtightness and preventing leakage.

[0048] Working principle: When using this sampler, the sampler is first turned on by the controller 901, so that the cooling tube 4 can draw in the gas and then deliver the gas into the gas storage bottle 7. During the delivery of the gas through the cooling tube 4, the cooling element 5 cools the cooling tube 4, thereby cooling the collected gas. The heat dissipation fins 6 absorb the heat released by the cooling element 5, and the heat is delivered to the outside of the sampler by the fan 2 for cooling. By cooling the sampled gas in advance, the sample distortion caused by high temperature can be avoided, and the accuracy of subsequent detection data can be improved.

[0049] When the filter plate 15 needs to be disassembled and replaced, pull the push button 12 to move the sliding column 11. The sliding column 11 will then move the locking block 13. When the locking block 13 slides out of the inner wall of the filter plate 15, the limiting position on the filter plate 15 is released. Then, rotate the push plate 17 to move it away from the surface of the filter plate 15. The filter plate 15 can then be pulled out through the handle 16 for quick disassembly. When the filter plate 15 needs to be installed, first place the filter plate 15 into the inner wall of the filter frame 10, and then use the spring... The elastic force of spring 14 pushes the locking block 13 into the inner wall of the filter plate 15 to achieve the limiting and fixing effect. Then, the push plate 17 is rotated so that the push plate 17 is on the upper surface of the filter plate 15. The elastic force of spring 20 pushes the limiting ring 19 to slide downward, thereby driving the connecting column 18 and the push plate 17 to slide downward. This increases the downward pressure of the push plate 17 on the filter plate 15, improving the airtightness. The quick disassembly and installation of the filter plate 15 allows the staff to quickly replace the filter plate 15, making it convenient to perform regular cleaning and maintenance of the filter plate 15 and improving maintenance efficiency.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
