Description

Technical Field

[0001] This utility model relates to the field of waste gas sampling technology, and in particular to an organic waste gas sampling device. Background Technology

[0002] An organic waste gas sampling device is a device used to collect and analyze organic waste gases generated during industrial production processes. Organic waste gases typically refer to gases containing volatile organic compounds, which may pose hazards to the environment and human health. Therefore, accurate collection and analysis of these waste gases is crucial for environmental monitoring.

[0003] Before emitting organic waste gas, each exhaust device has a different sampling point. When the sampling point location changes, in different workshops or at different emission outlets, it may be necessary to disassemble and move the entire sampling device. Due to changes in diameter or multi-layer arrangement, most sampling probes may only be fixed in a certain position, making it difficult to penetrate deep into the center of the pipe or the turbulent uniform area. As a result, the collected waste gas samples cannot represent the overall emission concentration, the data accuracy drops significantly, and the operational complexity and time cost increase. Frequent manual disassembly and cleaning are required, affecting the continuity of monitoring. Organic waste gas may contain particulate matter, dust, oil mist, or other impurities. These impurities can directly enter the sampling system. Particulate matter may clog the sampling pipeline, pump, or sensor, leading to sampling failure or equipment damage. When the storage container needs to be replaced, the operation process becomes cumbersome. This reduction in efficiency is even more pronounced in scenarios requiring multi-point, high-frequency sampling, which may lead to the failure to complete the sampling task on time. The collected waste gas may leak out through pores, affecting the normal operation of the entire sampling device, impacting the accuracy and reliability of the sampling work, and causing damage to the internal components of the sampling device.

[0004] The main purpose of this invention is to provide an organic waste gas sampling device, which can effectively solve the problems described in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an organic waste gas sampling device, comprising a housing, two support rings fixedly connected to the left end of the housing, an internally threaded ring fixedly connected to the right end of the housing, a rack ring disposed in the internal slot of the housing, the inner wall of the rack ring having an internally threaded portion, a protective box fixedly connected to the top of the housing, a motor disposed on the right side of the inside of the protective box, a rotating rod fixedly connected to the output end of the motor, a gear fixedly connected to the outer side of the left end of the rotating rod, the bottom of the gear meshing with the outer side of the rack ring, a threaded conveying pipe disposed inside the housing, the outer side of the threaded conveying pipe slidably connected to the inside of the internally threaded portion, the left end of the threaded conveying pipe disposed inside the support ring, and the right end of the threaded conveying pipe slidably connected to the inside of the internally threaded ring.

[0006] Furthermore, an air inlet is fixedly connected to the left end of the threaded conveying pipe, and a suction nozzle is connected to the left end of the air inlet. A hinge frame is fixedly connected to the bottom of the outer shell, and a handle is rotatably connected inside the hinge frame. A handle is fixedly connected to the inner rear side wall of the outer shell.

[0007] Furthermore, a support frame is connected through the rear side wall of the outer shell, and a device box is threadedly connected to the outer side of the support frame. Four sliding grooves are opened on the inner wall of the suction nozzle, and an installation groove is opened inside the suction nozzle. The rear sides of the four sliding grooves are correspondingly set with the installation groove.

[0008] Furthermore, four limiting plates are fixedly connected inside the mounting groove, a filter plate is provided inside the suction nozzle, and a first slider is fixedly connected to the outer side of the filter plate. The outer sides of the four first sliders are correspondingly arranged with the four sliding grooves. The four first sliders are all located inside the mounting groove, and a debris discharge hole is opened on the bottom wall of the front side of the suction nozzle.

[0009] Furthermore, the device box is equipped with a pump, the input end of which is fixedly connected to a bellows, the left end of which is connected to the right end of a threaded conveying pipe, the output end of which is fixedly connected to a connecting pipe, and the bottom left end of the connecting pipe is connected to a storage box.

[0010] Furthermore, a guide rail plate is fixedly connected to the bottom of the outer shell, a limit block is fixedly connected to the right side wall of the guide rail plate, mounting holes are provided on the left side wall of the guide rail plate, and a second slider is slidably connected inside the guide rail plate.

[0011] Furthermore, the bottom wall of the second slider is fixedly connected to the top wall of the storage box, a baffle is provided on the left side of the guide rail plate, and positioning pins are fixedly connected to the right side wall of the baffle. The outer side of the positioning pin is corresponding to the inside of the mounting hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through its rack ring, internal thread, motor, rotating rod, gear, and threaded delivery pipe, solves the problems that lead to collected exhaust gas samples failing to represent the overall emission concentration, significantly reducing data accuracy, increasing operational complexity and time costs, requiring frequent manual disassembly and cleaning, and affecting monitoring continuity. When the rack ring rotates, the internal thread inside the rack ring engages with the outer side of the threaded delivery pipe, allowing the threaded delivery pipe to not only rotate around its own axis but also slide left and right along its own axis within the support ring and internal thread ring under the drive of the rack ring. The left end of the threaded delivery pipe is supported by two support rings, ensuring stability during rotation and sliding, while the right end is slidably connected inside the internal thread ring, providing guidance and support for its movement. This effectively improves the versatility and flexibility of the device, shortens sampling time, increases work efficiency, reduces manual intervention, and lowers operational difficulty.

[0014] 2. By incorporating a sliding groove, limiting plate, filter plate, waste discharge hole, pump, storage tank, mounting hole, baffle, and positioning pin, the system effectively addresses issues that could affect the normal operation of the entire sampling device, compromising the accuracy and reliability of sampling, and causing damage to the internal components. When the filter plate is rotated, the four outer sliders align with the inside of the sliding groove. Disassembly is then completed by simply pulling the filter plate outwards along the sliding groove. When the storage tank is full of waste gas, or when it needs replacement for internal waste gas testing, simply remove the positioning pin on the baffle, remove the baffle, and slide the storage tank along the guide rail for convenient replacement and processing. This effectively improves the accuracy and reliability of sampling, enhances the safety of equipment and operators, reduces equipment damage and maintenance costs, and minimizes downtime during the sampling process.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figure 1 - Figure 4As shown: an organic waste gas sampling device includes a housing 1. Two support rings 2 are fixedly connected to the left end of the interior of the housing 1, and an internal threaded ring 3 is fixedly connected to the right end of the interior of the housing 1. The support rings 2 and the internal threaded ring 3 support the left and right ends of the threaded conveying pipe 10 inside the housing 1 and seal the left and right ends of the interior of the housing 1 to prevent gas from leaking out through the gaps inside the housing 1.

[0033] A rack ring 4 is installed in the internal slot of the outer casing 1. The inner wall of the rack ring 4 has an internal thread 5. A protective box 6 is fixedly connected to the top of the outer casing 1. A motor 7 is installed on the right side inside the protective box 6. A rotating rod 8 is fixedly connected to the output end of the motor 7. A gear 9 is fixedly connected to the outer side of the left end of the rotating rod 8. The bottom of the gear 9 meshes with the outer side of the rack ring 4. A threaded conveying pipe 10 is installed inside the outer casing 1. The outer side of the threaded conveying pipe 10 is slidably connected to the inside of the internal thread 5. The left end of the threaded conveying pipe 10 is installed inside the support ring 2. The right end of the threaded conveying pipe 10 is slidably connected to the inside of the internal thread ring 3. The protective box 6 is used to protect the motor 7 inside and to fix the motor 7 to the top of the outer casing 1. When it is necessary to detect the exhaust gas inside the exhaust device at different depths, the motor 7 is started. The output end of the motor 7 will drive the rotating rod 8 to rotate. By fixing the gear 9 to the outer side of the rotating rod 8, the gear 9 will rotate synchronously after the rotating rod 8 is driven. The rack ring 4 is placed in the slot opened in the middle of the outer casing 1, and the rack ring 4 meshes with the gear 9, so that the gear 9 is driven to drive the rack ring 4 to rotate inside the outer casing 1.

[0034] In addition, when the rack ring 4 rotates, the internal thread 5 inside the rack ring 4 engages with the outer side of the threaded delivery pipe 10, causing the threaded delivery pipe 10 to slide left and right inside the housing 1 under the drive of the rack ring 4, thereby extending the suction port to sample from the exhaust device at different locations.

[0035] When the device needs to be restored to its original state after sampling, the motor 7 is rotated in the opposite direction, causing the gear 9 and rack ring 4 to rotate in the opposite direction. This causes the internal threaded part 5 to drive the threaded delivery tube 10 to slide to the right and retract into the interior of the outer shell 1, thus storing the device.

[0036] like Figure 1 - Figure 9 As shown, the left end of the threaded conveying pipe 10 is fixedly connected to the air inlet 11, and the left end of the air inlet 11 is connected to the suction nozzle 12. The suction nozzle 12 on the air inlet 11 serves as the inlet for sucking in exhaust gas, and the exhaust gas is sucked into the interior of the air inlet 11 through the suction nozzle 12 by activating the pump 24 on the right side.

[0037] A hinge frame 13 is fixedly connected to the bottom of the outer casing 1. A handle 14 is rotatably connected inside the hinge frame 13. A handle 15 is fixedly connected to the inner rear side wall of the outer casing 1. The operator can flexibly control the position and direction of the device by using the handle 14 rotatably connected inside the hinge frame 13 at the bottom of the outer casing 1 and the handle 15 fixedly connected to the inner rear side wall of the outer casing 1, and align the suction nozzle 12 with the source of organic waste gas that needs to be sampled.

[0038] A support frame 16 is connected through the rear side wall of the outer casing 1, and a device box 17 is threadedly connected to the outer side of the support frame 16. The support frame 16 and the device box 17 are used to protect the pump 24 from the outside and support its bottom. The inner wall of the suction nozzle 12 has four sliding grooves 18, and the inside of the suction nozzle 12 has an installation groove 19. The rear sides of the four sliding grooves 18 are corresponding to the installation groove 19. Four limiting plates 20 are fixedly connected inside the installation groove 19. A filter plate 21 is installed inside the suction nozzle 12. The outer side of the filter plate 21 is fixedly connected to a first slider 22. The outer side of the four first sliders 22 is corresponding to the four sliding grooves 18. The four first sliders 22 are all set inside the installation groove 19. A debris discharge hole 23 is opened on the bottom wall of the front side of the inside of the suction nozzle 12. During installation, the first slider 22 is aligned with the sliding groove 18 and inserted to ensure that the filter plate 21 is accurately inserted into the installation position. The four limiting plates 20 inside the installation groove 19 are rectangularly distributed. When the filter plate 21 is fully inserted, the limiting plates 20 constrain it from four directions to prevent the filter plate 21 from shifting or shaking under the impact of airflow. The edges of the limiting plates 20 are designed with rounded transitions to avoid scratching the surface of the filter plate 21.

[0039] When the filter plate 21 needs to be replaced, rotate the filter plate 21 so that the four first sliders 22 on the outside are aligned with the inside of the slide groove 18. Then, simply pull the filter plate 21 outward along the slide groove 18 to complete the disassembly.

[0040] like Figure 1 - Figure 13 As shown, a pump 24 is installed inside the device box 17. A bellows 25 is fixedly connected to the input end of the pump 24. The left end of the bellows 25 is connected to the right end of the threaded conveying pipe 10. After the pump 24 is started, the suction force generated by the pump 24 will be transmitted to the inside of the threaded conveying pipe 10 through the bellows 25, and the exhaust gas drawn in through the suction nozzle 12 will be sucked into the inside of the pump 24.

[0041] In addition, the corrugated pipe 25 is connected to the threaded delivery pipe 10. When the threaded delivery pipe 10 slides to the left, it stretches the corrugated pipe 25, making the corrugated pipe 25 longer. This prevents the connection from falling off when the threaded delivery pipe 10 slides, thus preventing the gas from being accurately delivered into the pump 24.

[0042] The output end of the pump 24 is fixedly connected to a connecting pipe 26. The bottom left end of the connecting pipe 26 is connected to a storage tank 27. The exhaust gas is drawn through the bellows 25 at the input end of the pump 24 and transported to the inside of the storage tank 27 for storage through the connecting pipe 26 at the output end of the pump 24.

[0043] A guide rail plate 28 is fixedly connected to the bottom of the outer casing 1. A limit block 29 is fixedly connected to the right side wall of the guide rail plate 28. Mounting holes 30 are provided on the left side wall of the guide rail plate 28. A second slider 31 is slidably connected inside the guide rail plate 28. The bottom wall of the second slider 31 is fixedly connected to the top wall of the storage box 27. A baffle 32 is provided on the left side of the guide rail plate 28. A positioning pin 33 is fixedly connected to the right side wall of the baffle 32. The outer side of the positioning pin 33 corresponds to the inside of the mounting hole 30.

[0044] When the storage box 27 is full and needs to be disassembled for testing, first remove the positioning pin 33 on the baffle 32 from the positioning pin 33 on the left side of the guide plate 28, and the baffle 32 can be removed. Then, by pulling the storage box 27 to the left, the second slider 31 on the top of the storage box 27 slides out inside the guide plate 28. At the same time, the left end of the connecting pipe 26 will leave the inside of the storage box 27. Then, the right side of the storage box 27 will be sealed with a plug to prevent gas leakage and to disassemble the storage box 27.

[0045] After the gas level inside the storage tank 27 has been checked and cleaned, the second slider 31 on the top of the storage tank 27 is inserted into the interior of the guide plate 28 and slid to the right. When the storage tank 27 is pushed to the far right, the second slider 31 is limited by the limiting block 29 on the rear side of the guide plate 28 to prevent excessive sliding and disengagement from the interior of the guide plate 28. After the second slider 31 is installed inside the guide plate 28, the positioning pin 33 on the baffle 32 is aligned with the mounting hole 30 on the left side of the guide plate 28, and the positioning pin 33 is inserted into the mounting hole 30 to fix the baffle 32 on the left side of the guide plate 28 to prevent the second slider 31 from falling off.

[0046] It should be noted that this utility model is an organic waste gas sampling device. First, the motor 7 and the pump 24 are connected to an external power source or battery and a control panel to supply power and control the device.

[0047] When the motor 7 inside the protective box 6 is powered on, it drives the rotating rod 8 at the output end to rotate. The gear 9 at the left end of the rotating rod 8 rotates along with it and meshes with the teeth on the outer side of the rack ring 4, driving the rack ring 4 to make circular motion in the internal slot of the outer shell 1.

[0048] When the rack ring 4 rotates, the internal thread 5 inside the rack ring 4 engages with the outer side of the threaded conveying pipe 10, allowing the threaded conveying pipe 10 to not only rotate around its own axis but also slide left and right within the support ring 2 and the internal thread ring 3 along its own axis under the drive of the rack ring 4. The left end of the threaded conveying pipe 10 is supported by two support rings 2, ensuring its stability during rotation and sliding, while the right end is slidably connected inside the internal thread ring 3, providing guidance and support for its movement.

[0049] The movement of the threaded conveying pipe 10 initiates the collection of waste gas. The inlet hopper 11, fixedly connected to the left end of the threaded conveying pipe 10, and the suction nozzle 12, communicating with the left end of the inlet hopper 11, constitute the waste gas inlet. When the threaded conveying pipe 10 rotates and slides, a negative pressure is created at the suction nozzle 12, drawing in external organic waste gas. The drawn-in waste gas enters the interior of the threaded conveying pipe 10 through the inlet hopper 11, and as the threaded conveying pipe 10 rotates and slides, the waste gas is continuously propelled forward within the pipe.

[0050] When organic waste gas enters the device through the suction nozzle 12, it first comes into contact with the filter plate 21. The filter plate 21 adopts a high-density filter structure, which can intercept solid particles, dust, and large impurities in the waste gas, ensuring the accuracy of subsequent sampling and analysis. The intercepted impurities gradually deposit on the bottom wall of the front side inside the suction nozzle 12 under the impact of airflow and their own gravity. The specially designed discharge hole 23 here communicates with the outside. When the deposited impurities accumulate to a certain weight, they will automatically be discharged from the device through the discharge hole 23 to avoid secondary pollution.

[0051] Four first sliders 22 are evenly distributed on the outer side of the filter plate 21, precisely corresponding to the four sliding grooves 18 opened on the inner front side of the suction nozzle 12. During installation, the sliders 22 are aligned with the sliding grooves 18 and inserted to form a linear guide structure, ensuring that the filter plate 21 accurately enters the installation position. The four limiting plates 20 inside the installation groove 19 are rectangularly distributed. After the filter plate 21 is fully inserted, the limiting plates 20 constrain it from four directions to prevent the filter plate 21 from shifting or shaking under the impact of airflow. The edges of the limiting plates 20 are designed with rounded transitions to avoid scratching the surface of the filter plate 21.

[0052] When the filter plate 21 needs to be replaced, rotate the filter plate 21 so that the four outer sliders 22 are aligned with the inside of the slide groove 18. Then, simply pull the filter plate 21 outward along the slide groove 18 to complete the disassembly.

[0053] The motor 7 inside the protection box 6 drives the threaded conveying pipe 10 to rotate and slide, transporting the organic waste gas sucked in by the suction nozzle 12 to the right end of the threaded conveying pipe 10. At this time, the pump 24 inside the device box 17 starts to work. After the pump 24 starts, it creates a negative pressure suction force, which further extracts and transports the waste gas from the right end of the threaded conveying pipe 10 through the corrugated pipe 25. Under the suction force of the pump 24, the waste gas passes through the corrugated pipe 25 and the connecting pipe 26, and is finally transported to the storage box 27 for storage. The storage box 27 is responsible for collecting the collected organic waste gas and providing samples for subsequent detection and analysis.

[0054] The second slider 31, fixedly connected to the top of the storage box 27, can slide inside the guide rail plate 28. After the storage box 27 is slid into place along the guide rail plate 28, the limiting block 29 on the right side wall of the guide rail plate 28 acts as a stop to prevent the storage box 27 from sliding excessively. Then, the positioning pin 33 on the baffle 32 is inserted into the mounting hole 30 on the left side wall of the guide rail plate 28 to fix the baffle 32, thereby stably fixing the storage box 27 on the guide rail plate 28 and ensuring that the storage box 27 will not move arbitrarily during the sampling process.

[0055] When the waste gas in the storage box 27 is full, or when the storage box 27 needs to be replaced for testing of the waste gas inside, simply pull out the positioning pin 33 on the baffle 32, remove the baffle 32, and then slide the storage box 27 along the guide rail 28 for easy replacement and processing, thus preparing for subsequent sampling work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
