Description

Technical Field

[0001] The present invention relates to the technical field of air carbon emission detection, and particularly to a carbon emission detection device and a detection method for environmental protection. Background Art

[0002] In recent years, the continuous development of sensor technology, Internet of Things technology, big data analysis technology, and artificial intelligence algorithms has provided technical support for the innovation of carbon emission detection devices and methods. The common infrared light detection method uses the absorption characteristics of carbon dioxide for specific infrared light to measure its concentration, that is, a beam is emitted through a sample by an infrared source, and the change in light intensity is measured by an infrared detector to calculate the concentration. However, a large number of dust particles in the air to be detected will absorb infrared rays during detection, interfering with the detection accuracy. Therefore, a filter is often added to the device to filter other impurities in the air that do not contain carbon for pre-treatment to ensure the filtering effect. However, over time, it is prone to clogging, weakening the effect of the filter, and requiring frequent replacement, which hinders the air from entering the detection position and further affects the detection accuracy and quality.

[0003] For example, the prior art with the application number CN117451440A provides a carbon emission detection device for environmental protection, which includes a support rod, a device housing, a detection device, and a filtering device. The support rod is fixedly connected to the device housing, and a solar panel and a wind vane are sequentially installed at the top of the device housing. The solar panel at the top of the device housing can provide energy for the motor of the device, and the wind vane and an anemometer can detect the wind direction and wind speed of the external environment to control the direction and the fan. The filtering device installed at the front end inside the device housing includes a filter screen, a filter paper cylinder 1, a filter paper cylinder 2, and filter paper, which can efficiently filter impurities in the air and facilitate the replacement of the filter paper. The steering motor can automatically adjust the orientation of the device to improve the air detection efficiency. By combining the method of automatic suction and air self-flow detection, energy is saved and the detection efficiency is improved, and a Bourdon tube pressure gauge accurately measures the volume of gas entering the device.

[0004] From the actual use of the above prior art, it is known that it mainly combines the method of automatic suction and air self-flow detection through the detection device and the filtering device to save energy and improve the detection efficiency. However, during actual use, it is found that before the pre-treatment of filtration, since it is set to replace the filter paper for filtration, other impurities in the air that do not contain carbon are easily attached to the filter paper to form multiple layers of accumulation, clogging the filter holes. It can only choose to replace the filter paper frequently, with low utilization rate and high cost, and cannot perform anti-clogging treatment in time during filtration, affecting the filtration and carbon emission detection efficiency. Therefore, according to the actual use situation, the above prior art is improved. Summary of the Invention

[0019] Further: The sliding block includes square limiting blocks provided on the outer side wall of one end of the top.

[0020] A detection method for a carbon emission detection device for environmental protection, the method includes the following steps:

[0021] Step 1: The operator fixes this device through two sets of fixing screws with the same structure symmetrically arranged on both sides of the base. When pre-filtering the air, the existing technology wind vane body and anemometer body are used to detect the wind speed and direction, and transmit the detected electrical signals to the plc controller. The plc controller then transmits the electrical signals and triggers the rotation of the rotating motor body installed at the top of the support rod, driving the end of the rotating motor body's actuator to rotate and connect to the detection box shell facing the windward side, so that the air to be detected enters the inner cavity of the detection box shell through natural flow. The nickel alloy filter screen arranged on the inner side wall of the filter screen frame is used to filter other impurities in the air that do not contain carbon. The nickel alloy filter screen has good chemical stability, is not easy to chemically react with gases involved in carbon emission detection such as carbon dioxide and carbon monoxide, and will not adsorb these gases in large quantities, which can ensure the accuracy of the detection results to a certain extent. Moreover, the nickel alloy filter screen can effectively intercept and filter various solid particles in the air or fluid, such as dust, pollen, metal debris, fibers and other impurities that affect and interfere with the detection of carbon emissions, and has good mechanical strength. After these filtered air passes through the nickel alloy filter screen, it will be detected for carbon emissions by the infrared carbon emission detector body arranged on the side wall of the inner cavity of the detection box shell, completing the filtered detection of carbon emissions;

[0022] Step 2: When conducting the next carbon emission detection, first, the existing technology camera arranged at the middle position of the side wall of the inner cavity adjacent to the two groups of fans in the detection box shell captures images of the impurities attached to the nickel alloy filter screen to determine whether to clean the filter screen. When cleaning, the camera sends an electrical signal to the plc controller, and the plc controller then transmits the electrical signal and triggers the actuator of the motor to drive one end provided with a first driving connecting plate to rotate and support the rotation through a support plate rotatably connected to one end of the actuator of the motor. The rotation of the first driving connecting plate drives the rotation shaft rod provided at one end of the top and the second driving connecting plate provided at the other end of the rotation shaft rod to rotate and be fixedly supported and rotated through the bottom end side wall of the second driving connecting plate rotatably connected to the side wall of the inner cavity of the installation shell. Moreover, the rotation of the rotation shaft rod drives the driving circular surface shaft rod rotatably connected to the outer side wall of the middle position to reciprocate up and down in the inner cavity of the detection box shell through being embedded in the square moving groove. Since the rotation shaft rod is arranged at one end of the side wall of the top of the first driving connecting plate and the second driving connecting plate, when rotating, the driving circular surface shaft rod will make a reciprocating motion up and down, and the reciprocating motion up and down of the driving circular surface shaft rod will also drive the connecting plate and the abutting plate rotatably connected to the bottom end to make the same motion;

[0023] Step 3: The reciprocating motion of the upper and lower parts of the abutting plate drives two groups of partition plates with the same structure symmetrically arranged on the outer wall of one side of the bottom of the abutting plate. Filter screen frames are arranged on the side walls of the two partition plates, and two groups of sliders with the same structure are symmetrically arranged on the outer walls of both sides of the two partition plates. The sliders perform reciprocating up-and-down support movements on the inner walls of the support sliding grooves that match the sliders on the side walls of the support sliding seats. When the abutting plate performs reciprocating up-and-down support movements, it will also drive the pressing plate to perform reciprocating up-and-down support movements on the inner walls of the support sliding grooves that match the pressing plate on the side walls of the sliding-connected support sliding seats. At the same time, the reciprocating up-and-down support movement of the pressing plate drives the springs installed on the outer wall of the top to compress and rebound on the top side wall of the support sliding seat. A sliding block is arranged on the outer wall of the top of the pressing plate adjacent to one side of the spring. The sliding block is slidably connected to the top side wall of the support sliding seat and generates a sliding displacement during the reciprocating up-and-down movement, so as to support the compression and rebound of the spring by the pressing plate, which is convenient for increasing the vibration generated by the reciprocating up-and-down movement and reducing noise. Through the above reciprocating up-and-down movement operation, the centrifugal force and vibration generated by the reciprocating up-and-down movement of the nickel alloy filter screen arranged on the inner side wall of the filter screen frame are used to timely make the impurities attached to the filter paper by the nickel alloy filter screen fall off by gravity into the impurity extraction and storage box slidably connected to the side wall of the bottom of the adjacent opening and closing sealing door of the detection box shell, avoiding clogging the filter holes and affecting the filtration and carbon emission detection efficiency. Moreover, it is not necessary to frequently replace the filter screen, which improves the utilization rate and reduces the use cost. The operation is convenient, the structure is simple, and the accuracy of the next carbon emission detection is improved;

[0024] Step 4: The horizontal baffles arranged on the outer walls of the tops of the partition plates are convenient for blocking the falling impurities from running upward, and the inclined baffles arranged on the outer walls of one side of the bottoms of the partition plates block the falling impurities from running to both sides and guide them into the impurity extraction and storage box. Generally, the proportion of impurities attached to the side of the nickel alloy filter screen facing the air inlet of the detection box shell is large, and the proportion of impurities attached to the side facing the infrared carbon emission detector body is small. Because of the layer-by-layer filtration, when there is no wind, the fan speeds up the extraction of air into the detection box shell. Two groups of fixing screws with the same structure are threadedly connected to the outer side walls on both sides of the filter screen frame, and one end of each fixing screw is threadedly connected to the side walls on both sides of the nickel alloy filter screen support for threaded connection and disassembly to replace the nickel alloy filter screen.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: The anti-clogging pre-filtering component of the present invention is convenient for timely preventing the filter screen from being clogged during filtration, avoiding other impurities in the air that do not contain carbon from easily adhering to the filter paper to form multiple layers of accumulation, clogging the filter holes, and affecting the filtration and carbon emission detection efficiency. Moreover, it is not necessary to frequently replace the filter screen, which improves the utilization rate and reduces the use cost. The operation is convenient and the structure is simple.

[0044] Among them, preferably, the anti-blocking pre-filtering component 8 includes a mounting shell 81 arranged on the outer side wall at the middle position of the top of the detection box housing 4. A motor 88 is installed on the inner cavity side wall of the mounting shell 81 at intervals. One end of the execution end of the motor 88 is rotatably connected to a support plate 82.

Since the rotating shaft rod 84 is arranged at one end of the side wall at the top of the first driving connecting plate 83 and the second driving connecting plate 89, when rotating, the driving circular surface shaft rod 85 will make a reciprocating up and down movement, and the reciprocating up and down movement of the driving circular surface shaft rod 85 will also drive the connecting plate 86 rotatably connected to one end of the bottom and the abutting plate 871 to perform the same movement.

[0052] A detection method for a carbon emission detection device for environmental protection, the method comprising the following steps:

[0053] Step 1: The operator fixes this device through two groups of fixing screws 10 with the same structure symmetrically arranged on both sides of the base 1. When pre-filtering the air, the wind vane body 7 and the anemometer body 6 in the prior art are used to detect the wind speed and direction, and transmit the detected electrical signals to the plc controller. The plc controller then transmits the electrical signals and triggers the rotation of the rotation motor body 3 installed at the top of the support rod 2, driving the execution end of the rotation motor body 3 to rotate and connect the detection box shell 4 facing the windward side. The air to be detected enters the inner cavity of the detection box shell 4 through natural flow. The nickel alloy filter screen 8731 arranged on the inner side wall of the filter screen frame 873 is used to filter other impurities in the air that do not contain carbon. The nickel alloy filter screen 8731 has good chemical stability, is not easy to chemically react with gases involved in carbon emission detection such as carbon dioxide and carbon monoxide, and will not adsorb these gases in large quantities, which can ensure the accuracy of the detection results to a certain extent. Moreover, the nickel alloy filter screen 8731 can effectively intercept and filter various solid particles in the air or fluid, such as dust, pollen, metal debris, fibers and other impurities that affect and interfere with the detection of carbon emissions, and has good mechanical strength. After passing through the nickel alloy filter screen 8731, these filtered air will be detected for carbon emissions by the infrared carbon emission detector body 41 arranged on the inner cavity side wall of the detection box shell 4, completing the filtering detection of carbon emissions;

[0054] Step 2: When performing the next carbon emission detection, first, the camera 43 in the prior art arranged at the middle position of the inner cavity side wall adjacent to the two groups of fans 42 in the detection box shell 4 captures images of the impurities attached to the nickel alloy filter screen 8731 to judge whether to clean the filter screen. When cleaning, the camera 43 sends an electrical signal to the plc controller, and the plc controller then transmits the electrical signal and triggers the execution end of the motor 88 to drive one end provided with the first driving connecting plate 83 to rotate and be supported and rotated by the support plate 82 rotatably connected to one end of the execution end of the motor 88. The rotation of the first driving connecting plate 83 drives the rotation shaft rod 84 provided at one end of the top and the other end of the rotation shaft rod 84 provided with the second driving connecting plate 89 to rotate and be fixedly supported and rotated by being rotatably connected to the inner cavity side wall of the installation shell 81 at the bottom end side wall of the second driving connecting plate 89 at the same time. Moreover, the rotation of the rotation shaft rod 84 drives the driving circular surface shaft rod 85 rotatably connected to the outer side wall at the middle position to reciprocate up and down in the detection box shell 4 through being embedded in the square movable groove 44. Since the rotation shaft rod 84 is arranged at one end of the side wall at the top of the first driving connecting plate 83 and the second driving connecting plate 89, when rotating, the driving circular surface shaft rod 85 will make a reciprocating motion up and down, and the reciprocating motion up and down of the driving circular surface shaft rod 85 will also drive the connecting plate 86 and the abutting plate 871 rotatably connected to the bottom end to perform the same motion;

[0055] Step 3: The reciprocating motion of the upper and lower parts of the abutting plate 871 drives two groups of partition plates 872 with the same structure symmetrically arranged on the outer wall of one side of the bottom of the abutting plate 871. Filter screen frames 873 are arranged on the side walls of the two partition plates 872, and two groups of sliders 874 with the same structure are symmetrically arranged on the outer walls of both sides of the two partition plates 872. The sliders 874 perform reciprocating up and down support motions on the inner walls of the support sliding grooves 8751 that match the sliders 874 and are opened on the side walls of the support sliding seats 875. When the abutting plate 871 performs reciprocating up and down support motions, it will also drive the pressing plate 876 to perform reciprocating up and down support motions on the inner walls of the support sliding grooves 8751 that match the pressing plate 876 and are opened on the side walls of the support sliding seats 875 where the pressing plate 876 is slidably connected. At the same time, the reciprocating up and down support motion of the pressing plate 876 drives the springs 8761 installed on the outer wall of the top to be compressed and rebound on the top side wall of the support sliding seat 875. A sliding block 8762 is arranged on the outer wall of the top of the pressing plate 876 adjacent to one side of the spring 8761. The sliding block 8762 performs reciprocating up and down motions while slidingly connected to the top side wall of the support sliding seat 875, generating a sliding displacement, so as to support the compression and rebound of the spring 8761 by the pressing plate 876, facilitating increasing the vibration generated by the reciprocating up and down motion and reducing the noise. Through the above reciprocating up and down motion operation, the centrifugal force and vibration generated by the reciprocating up and down motion of the nickel alloy filter screen 8731 arranged on the inner side wall of the filter screen frame 873 facilitate the timely shedding of the multilayered accumulated impurities attached to the filter paper by the nickel alloy filter screen 8731 under the action of gravity into the impurity extraction and storage box 9 that is slidably connected to the side wall of the bottom of the adjacent opening and closing sealing door 5 of the detection box housing 4, avoiding clogging the filter holes and affecting the filtration and carbon emission detection efficiency, and not requiring frequent replacement of the filter screen, improving the utilization rate and reducing the use cost, with convenient operation, simple structure, and improving the accuracy of the next carbon emission detection;

[0056] Step 4: The horizontal baffles 8721 arranged on the outer walls of the tops of the partition plates 872 facilitate blocking the impurities that fall off and run upward, and the inclined baffles 8722 arranged on the outer walls of one side of the bottoms of the partition plates 872 block the impurities that fall off and run to both sides, guiding them into the impurity extraction and storage box 9. Generally, the proportion of impurities attached to the side of the nickel alloy filter screen 8731 facing the air inlet of the detection box housing 4 is large, and the proportion of impurities attached to the side facing the infrared carbon emission detector body 41 is small. Because of being filtered layer by layer, when there is no wind, the fan 42 accelerates the extraction of air into the detection box housing 4. Two groups of fixing screws 8732 with the same structure are threadedly connected to the outer walls on both sides of the filter screen frame 873, and one end of each of the two groups of fixing screws 8732 is threadedly connected to the side walls of both sides of the bracket of the nickel alloy filter screen 8731 for threaded connection and disassembly, for replacing the nickel alloy filter screen 8731.

[0057] Embodiment: At the beginning of operation, the operator fixes this device through two sets of fixing screws 10 with the same structure symmetrically arranged on both sides of the base 1. When pre-filtering the air, the wind vane body 7 and the anemometer body 6 in the prior art are used to detect the wind speed and direction and transmit the detected electrical signal to the plc controller. The plc controller then transmits the electrical signal and triggers the rotation of the rotating motor body 3 installed at the top of the support rod 2, driving the execution end of the rotating motor body 3 to rotate and connect the detection box shell 4 to face the windward side, so that the air to be detected enters the inner cavity of the detection box shell 4 through natural flow. The nickel alloy filter screen 8731 arranged on the inner side wall of the filter screen frame 873 is used to filter other impurities in the air that do not contain carbon. The nickel alloy filter screen 8731 has good chemical stability, is not easy to chemically react with gases involved in carbon emission detection such as carbon dioxide and carbon monoxide, and will not adsorb these gases in large quantities, which can ensure the accuracy of the detection results to a certain extent. Moreover, the nickel alloy filter screen 8731 can effectively intercept and filter various solid particles in the air or fluid, such as impurities that affect and interfere with the detection of carbon emissions, such as dust, pollen, metal debris, fibers, etc., and has good mechanical strength. After passing through the nickel alloy filter screen 8731, these filtered air will be detected for carbon emissions by the infrared carbon emission detector body 41 arranged on the inner cavity side wall of the detection box shell 4, completing the filtering detection of carbon emissions;

[0058] When conducting the next carbon emission detection, first, a prior art camera 43 is arranged at the middle position of the inner cavity side wall adjacent to the two groups of fans 42 in the detection box housing 4 to capture images of the impurities attached to the nickel alloy filter screen 8731 to determine whether to clean the filter screen. When cleaning, an electrical signal is sent to the plc controller through the camera 43, and the plc controller then transmits the electrical signal and triggers the execution end of the motor 88 to drive a first driving connecting plate 83 arranged at one end. The first driving connecting plate 83 is rotationally connected to a support plate 82 at one end of the execution end of the motor 88 for supporting rotation. The rotation of the first driving connecting plate 83 drives a rotating shaft rod 84 arranged at one end of the top and a second driving connecting plate 89 arranged at the other end of the rotating shaft rod 84. At the same time, the bottom end side wall of the second driving connecting plate 89 is rotationally connected to the inner cavity side wall of the installation housing 81 for fixed support rotation. The rotation of the rotating shaft rod 84 drives a driving circular surface shaft rod 85 whose outer side wall at the middle position is rotationally connected to reciprocate up and down in the inner cavity of the detection box housing 4 through the square moving groove 44. Since the rotating shaft rod 84 is arranged at one end of the side wall at the top of the first driving connecting plate 83 and the second driving connecting plate 89, when rotating, the driving circular surface shaft rod 85 will perform up and down reciprocating motion. The up and down reciprocating motion of the driving circular surface shaft rod 85 will also drive a connecting plate 86 and a contact plate 871 rotationally connected at the bottom end to perform the same motion. At the same time, the up and down reciprocating motion of the contact plate 871 drives two groups of partition plates 872 with the same structure symmetrically arranged on the outer side wall of one side of the bottom of the contact plate 871. Filter screen frames 873 are arranged on the side walls of the two groups of partition plates 872, and two groups of sliders 874 with the same structure are symmetrically arranged on the outer side walls of the two sides of the two groups of partition plates 872. The inner walls of the support sliding seats 875 are provided with support sliding grooves 8751 that match the sliders 874 to perform up and down supporting reciprocating motion. When the contact plate 871 performs up and down supporting reciprocating motion, it will also drive a pressing plate 876 to perform up and down supporting reciprocating motion on the inner wall of the support sliding groove 8751 that matches the pressing plate 876 and is arranged on the side wall of the support sliding seat 875 where the pressing plate 876 is slidably connected. At the same time, the up and down supporting reciprocating motion of the pressing plate 876 drives a spring 8761 installed on the outer side wall of the top to be compressed and rebound on the top side wall of the support sliding seat 875. A sliding block 8762 is arranged on the outer side wall of the top of the pressing plate 876 adjacent to one side of the spring 8761. The sliding block 8762 is slidably connected to the top side wall of the support sliding seat 875 and performs sliding displacement during up and down reciprocating motion, so as to support and compress and rebound the spring 8761 by the pressing plate 876, which is convenient for increasing the vibration generated by up and down reciprocating motion and reducing noise. Through the above up and down reciprocating motion operation, the centrifugal force and vibration generated by the up and down reciprocating motion of the nickel alloy filter screen 8731 arranged on the inner side wall of the filter screen frame 873 are used to timely cause the impurities formed by the nickel alloy filter screen 8731 attached to the filter paper to form multiple layers of accumulated impurities to fall off by gravity into an impurity drawer storage box 9 slidably connected to the bottom side wall adjacent to the opening and closing sealing door 5 of the detection box housing 4, avoiding blocking the filter holes and affecting the filtration and carbon emission detection efficiency, and not requiring frequent replacement of the filter screen, improving the utilization rate and reducing the use cost, and the operation is convenient.Simple structure and improved accuracy for the next carbon emission detection;

[0059] Transverse baffles 8721 are provided on the outer side walls of the top of the partition plate 872 to block the falling impurities from running upward, and inclined baffles 8722 are provided on the outer side walls of one side of the bottom of the partition plate 872 to block the falling impurities from running to both sides and divert them into the impurity extraction and storage box 9. Generally, the proportion of impurities attached to the side of the nickel alloy filter screen 8731 facing the air inlet of the detection box housing 4 is large, and the proportion of impurities attached to the side facing the infrared carbon emission detector body 41 is small. After being filtered layer by layer, when there is no wind, the fan 42 is used to accelerate the extraction of air into the detection box housing 4. Two groups of fixing screws 8732 with the same structure are threadedly connected to the outer side walls on both sides of the filter screen frame 873 to threadedly connect and disassemble the two ends threadedly connected to the side walls of the brackets of the nickel alloy filter screen 8731, so as to replace the nickel alloy filter screen 8731.

When pre-filtering the air, the existing technology wind vane body (7) cooperates with the anemometer body (6) to detect the wind speed and direction, transmit the detected electrical signal to the plc controller, and the plc controller then transmits the electrical signal and triggers the rotation of the rotating motor body (3) installed at the top of the support rod (2), driving the execution end of the rotating motor body (3) to rotate and connect the detection box shell (4) to face the windward side, so that the air to be detected enters the inner cavity of the detection box shell (4) through natural flow. The nickel alloy filter screen (8731) arranged on the inner side wall of the filter screen frame (873) is used to filter other impurities in the air that do not contain carbon. The nickel alloy filter screen (8731) has good chemical stability, is not easily chemically reactive with gases involved in carbon emission detection such as carbon dioxide and carbon monoxide, and will not adsorb these gases in large quantities, which can ensure the accuracy of the detection results to a certain extent. Moreover, the nickel alloy filter screen (8731) can effectively intercept and filter various solid particles in the air or fluid, such as impurities like dust, pollen, metal debris, and fibers that affect and interfere with the detection of carbon emissions, and has good mechanical strength. After passing through the nickel alloy filter screen (8731), these filtered air will be detected for carbon emissions by the infrared carbon emission detector body (41) arranged on the inner cavity side wall of the detection box shell (4), completing the filtering detection of carbon emissions; Step 2: When conducting the next carbon emission detection, first, the existing technology camera (43) arranged at the middle position of the inner cavity side wall adjacent to the two groups of fans (42) in the detection box shell (4) captures images of the impurities attached to the nickel alloy filter screen (8731) to determine whether to clean the filter screen. When cleaning, the camera (43) sends an electrical signal to the plc controller, and the plc controller then transmits the electrical signal and triggers the execution end of the motor (88) to drive one end provided with the first driving connecting plate (83) to rotate and be supported and rotated by the support plate (82) rotatably connected to one end of the execution end of the motor (88). The rotation of the first driving connecting plate (83) drives the rotation shaft rod (84) provided at one end of the top and the second driving connecting plate (89) provided at the other end of the rotation shaft rod (84) to be fixedly supported and rotated through the rotation of the bottom end side wall of the second driving connecting plate (89) connected to the inner cavity side wall of the installation shell (81). Moreover, the rotation of the rotation shaft rod (84) drives the driving circular surface shaft rod (85) rotatably connected to the outer side wall of the middle position to reciprocate up and down in the inner cavity of the detection box shell (4) through being embedded in the square movable groove (44). Since the rotation shaft rod (84) is arranged at one end of the side wall of the top of the first driving connecting plate (83) and the second driving connecting plate (89), when rotating, the driving circular surface shaft rod (85) will make a reciprocating motion up and down, and the reciprocating motion up and down of the driving circular surface shaft rod (85) will also drive the connecting plate (86) and the abutting plate (871) rotatably connected to the bottom end to perform the same motion; Step 3: The reciprocating movement of the upper and lower parts of the abutting plate (871) drives two groups of partition plates (872) with the same structure symmetrically arranged on the outer wall of one side of the bottom of the abutting plate (871).

The sliders (874) perform reciprocating up-and-down support movements on the inner wall of the support chute (8751) that matches the sliders (874) and is provided on the side wall of the support slide base (875). When the abutting plate (871) performs reciprocating up-and-down support movements, it will also drive the pressing plate (876) to perform reciprocating up-and-down support movements on the inner wall of the support chute (8751) that matches the pressing plate (876) and is provided on the side wall of the slidably connected support slide base (875). At the same time, the reciprocating up-and-down support movement of the pressing plate (876) drives the spring (8761) installed on the outer wall of the top to be compressed and rebound on the top side wall of the support slide base (875). A sliding block (8762) is arranged on the outer wall of the top of the pressing plate (876) adjacent to one side of the spring (8761). The sliding block (8762) performs reciprocating up-and-down movements while being slidably connected to the top side wall of the support slide base (875) to generate a sliding displacement, so as to support, compress, and rebound the spring (8761) by the pressing plate (876), which is convenient for increasing the vibration generated by the reciprocating up-and-down movement and reducing the noise. Through the above reciprocating up-and-down movement operation, the centrifugal force and vibration generated by the reciprocating up-and-down movement of the nickel alloy filter screen (8731) arranged on the inner side wall of the filter screen frame (873) facilitate the timely detachment of the impurities attached to the filter paper in multiple layers by gravity and fall into the impurity extraction and storage box (9) slidably connected to the side wall of the bottom of the detection box housing (4) adjacent to the opening and closing sealing door (5), avoiding blocking the filter holes and affecting the filtration and carbon emission detection efficiency.
