Description

Technical Field

[0001] This invention relates to the field of ozone concentration detection technology, specifically to an in-situ multi-channel wireless ozone concentration detection and calibration device. Background Technology

[0002] Ozone concentration detection is a technical means used to accurately measure the ozone content in the environment. It is mainly used in places where ozone concentration needs to be monitored, such as the ozone disinfection process in water treatment plants, clean rooms in hospitals or pharmaceutical factories, food processing workshops, and public places using ozone generators for air purification. Ozone concentration detection calibration equipment is a key tool used to periodically calibrate the aforementioned detection instruments. It generates standard ozone gas of known precise concentration to calibrate and correct online or portable detectors, thereby ensuring the long-term accuracy and reliability of all ozone measurement data used for safety protection or process control. It is an indispensable metrological foundation for ensuring the safety and compliance of ozone applications and the achievement of process standards.

[0003] A utility model patent with publication number CN217879110U discloses an ozone concentration detection device. By turning on an electrostatic generator, the device charges an adsorption plate with static electricity, thereby adsorbing larger dust particles in the air, increasing the accuracy of ozone concentration detection and effectively reducing the impact of dust on ozone concentration detection. However, when detecting ozone concentration at different locations, the device needs to be moved to the designated point multiple times, which is cumbersome. Summary of the Invention

[0008] An adjustment mechanism is installed inside the buffer box.

[0016] Preferably, the filtration mechanism further includes:

[0017] The outer pipe installed at the end of the fixed pipe away from the joint and the connecting pipe installed inside the outer pipe;

[0018] A second slide groove is formed inside the fixed tube, and the second slide plate is slidably connected to the inside of the second slide groove.

[0019] Preferably, the filtration mechanism further includes:

[0020] The first and second chambers are located inside the fixed tube;

[0021] A first movable plate and a second movable plate are installed on both sides of the second slide plate. The first movable plate is slidably connected to the inside of the first chamber, and the second movable plate is slidably connected to the inside of the second chamber. During the movement of the first movable plate and the second movable plate, the control fixing tube is closed.

[0022] Preferably, the filtration mechanism further includes:

[0023] The first filter plate installed below the second slide plate and the first filter hole opened inside the first filter plate;

[0024] The second telescopic rod is installed outside the first filter plate.

[0025] Preferably, the filtration mechanism further includes:

[0026] The third filter plate installed on the telescopic end of the second telescopic rod and the second filter plate disposed outside the third filter plate;

[0027] Second filter holes are formed inside the second and third filter plates.

[0028] Preferably, the adjusting mechanism further includes:

[0029] The first push rod is mounted on the fixed base installed inside the buffer box;

[0030] The connector is located on the telescopic end of the first push rod.

[0031] Preferably, the adjusting mechanism further includes:

[0032] An outer ring is installed on the outside of the moving tube, and the outer ring is connected to the connector.

[0033] A connecting plate is located on the outer ring, away from the connecting component;

[0034] A fixed rod and a limiting cylinder connected to the fixed rod are installed inside the buffer box. The limiting cylinder is adapted to the moving tube. The fixed rod passes through the outer ring, and the limiting cylinder is used to block the moving tube.

[0035] This invention provides an in-situ multi-channel wireless ozone concentration detection and calibration device. It has the following beneficial effects:

[0036] 1. This in-situ multi-channel ozone concentration wireless detection and calibration device uses three fixed tubes with three flexible hoses installed at different locations to achieve in-situ detection of ozone concentration in multiple gases. When using existing ozone concentration detection and calibration equipment, multiple relocations of the device to the designated point are required to detect ozone concentration at different locations, which is cumbersome. Therefore, this device uses three fixed tubes and a buffer box that can be connected to them to achieve in-situ detection of ozone concentration in multiple gases.

[0037] 2. This in-situ multi-channel wireless ozone concentration detection and calibration device employs a filtration mechanism and connects to a flexible hose via three fixed tubes at different angles, an outer tube, and a connecting tube, minimizing hose bending. Furthermore, the connecting tube features internal threaded grooves to increase friction between the connecting tube and the flexible hose, thereby reinforcing the hose and preventing it from loosening. The three fixed tubes, positioned in different directions, allow users to easily connect hoses in various orientations, enabling in-situ detection of ozone concentrations in multiple gas streams.

[0038] 3. This in-situ multi-channel wireless ozone concentration detection and calibration device, through the setting of an adjustment mechanism, incorporates fixed limiting cylinders in three moving tubes, which initially block the three moving tubes. Based on the direction of ozone concentration detection, the corresponding first push rod is adjusted, thereby controlling the connection between the moving tube and the corresponding connector. This facilitates gas entry while simultaneously blocking the other two moving tubes to prevent external gas from mixing into the buffer tank and affecting the detection results.

[0039] 4. This in-situ multi-channel wireless ozone concentration detection and calibration device, through the setting of a filtration mechanism and an adjustment mechanism, causes the first and second slide plates to move as the connecting plate moves. The second slide plate then moves the first, second, and third filter plates, thereby changing the relative positions of the multiple filter plates in the airflow channel and fine-tuning the filtration path of the gas flow. When the filter plates move, the particles attached to them are vibrated, making it easier for them to detach from the curved surface or the edges of the filter plates. Attached Figure Description

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0051] like Figures 1-9 As shown, the present invention provides a technical solution: an in-situ multi-channel wireless ozone concentration detection and calibration device, which is described below.

[0052] Including outer box 1, it also includes:

[0053] Mounting frame 2 is set on outer box 1;

[0054] The fixed tube 3, buffer box 5 and detection box 7 are installed inside the outer box 1. There are three fixed tubes 3, and the three fixed tubes 3 are set in different directions. The included angle between adjacent fixed tubes 3 is 60°. The buffer box 5 has a channel inside.

[0055] The filter mechanism 4 is disposed inside the fixed pipe 3, and the filter mechanism 4 includes a connector 406 installed outside the fixed pipe 3.

[0056] An adjustment mechanism 6 is installed inside the buffer box 5. The adjustment mechanism 6 includes a first push rod 602 installed inside the buffer box 5 and a moving tube 604 slidably connected inside the buffer box 5. The first push rod 602 is used to adjust the distance between the moving tube 604 and the connector 406. The first push rod 602 is set as an electric push rod. There are three of the first push rod 602 and three of the moving tubes 604. The positions of the three moving tubes 604 correspond to the positions of the three fixed tubes 3 respectively. The first push rod 602 drives the moving tube 604 to be sleeved on the outside of the connector 406. The moving tube 604 slides inside the channel.

[0057] The exhaust pipe 8 is installed outside the test box 7 and passes through the outer box 1;

[0058] A connecting pipe 9 is installed outside the buffer box 5. The end of the connecting pipe 9 furthest from the buffer box 5 is connected to the detection box 7. The height of the connecting pipe 9 is lower than the height of the moving pipe 604. The detection box 7 has two working spaces. The first working space connected to the connecting pipe 9 contains an optical detection probe and an ultraviolet lamp, which are located on opposite sides of the gas. The ultraviolet lamp emits ultraviolet light of a specific wavelength, which passes through the gas flowing through the first working space and is received by the probe on the other side. Ozone strongly absorbs ultraviolet light of this wavelength, so the probe can calculate the ozone concentration in the gas based on the degree of attenuation of the received light intensity. The second working space contains an air pump and an ozone treatment device. The first and second working spaces are connected by a suction pipe. The air pump draws the gas being tested into the second working space, and then the gas is treated by the ozone treatment device and discharged through the exhaust pipe 8.

[0059] A first slide 10 is formed inside the buffer box 5 and a first slide plate 11 is slidably connected inside the first slide 10. The first slide plate 11 is made of magnetic material.

[0060] The first telescopic rod 12 is installed on the first slide plate 11;

[0061] The second sliding plate 13 is installed on the telescopic end of the first telescopic rod 12.

[0062] Before using the equipment, select the location where the ozone concentration needs to be measured. Attach one end of the flexible hose to the corresponding fixed pipe 3, and place the other end of the hose at the location where the ozone concentration needs to be measured. Connect one end of another flexible hose to the outside of the exhaust pipe 8, and place the other end at the exhaust position. Then, adjust the adjustment mechanism to ensure proper connection between the fixed pipe 3 and the buffer box 5.

[0063] The air pump inside the detection chamber 7 is activated. Under the suction effect, the gas enters the fixed pipe 3 through the hose, passes through the filter mechanism 4 in the fixed pipe 3, enters the buffer chamber 5, and enters the first working space inside the detection chamber 7 through the connecting pipe 9 outside the buffer chamber 5. Ultraviolet light of a specific wavelength is emitted by the ultraviolet lamp in the first working space. After passing through the gas flowing through the first working space, it is received by the probe on the other side. Ozone strongly absorbs this wavelength of ultraviolet light, so the probe can calculate the ozone concentration in the gas based on the degree of light intensity attenuation. The detector is calibrated by comparing the ozone concentration with the reading of the detector at the location where the ozone concentration is to be detected. The gas that has passed through the detection chamber then enters the second working space through the suction pipe outside the first working space. After being treated by the ozone treatment equipment, the gas is discharged to the exhaust position through the exhaust pipe 8.

[0064] By setting up three fixed tubes 3 and installing three flexible tubes at different positions on the fixed tubes 3, in-situ detection of ozone concentration in multiple gases can be achieved. When using existing ozone concentration detection and calibration equipment, it is necessary to move the equipment to the designated point multiple times to detect ozone concentration at different locations, which is cumbersome. Therefore, setting up three fixed tubes 3 and a buffer box 5 that can be connected to them enables in-situ detection of ozone concentration in multiple gases.

[0065] Filter mechanism 4 also includes:

[0066] An outer tube 401 is installed at the end of the fixed tube 3 away from the joint 406, and a connecting tube 402 is installed inside the outer tube 401. A threaded groove is opened inside the connecting tube 402.

[0067] A second slide groove 403 is formed inside the fixed tube 3, and the second slide plate 13 is slidably connected to the inside of the second slide groove 403;

[0068] The first and second chambers are located inside the fixed tube 3;

[0069] The first movable plate 404 and the second movable plate 405 are installed on both sides of the second slide plate 13. The first movable plate 404 is slidably connected to the inside of the first chamber, and the second movable plate 405 is slidably connected to the inside of the second chamber.

[0070] The first filter plate 407 installed below the second slide plate 13 and the first filter hole 408 opened inside the first filter plate 407;

[0071] The second telescopic rod 409 is disposed outside the first filter plate 407;

[0072] The third filter plate 411 is installed on the telescopic end of the second telescopic rod 409 and the second filter plate 410 is disposed outside the third filter plate 411;

[0073] The second filter hole 412 is opened inside the second filter plate 410 and the third filter plate 411. The inner diameter of the second filter hole 412 is larger than the inner diameter of the first filter hole 408. The outer surface of the third filter plate 411 near the outer tube 401 is set to be arc-shaped, so that impurities can slide down along its arc-shaped outer surface.

[0074] The working process of connecting the filter mechanism 4 to the hose:

[0075] During the installation of the fixing pipe 3 and the hose, the hose is sleeved on the outside of the connecting pipe 402. Since the connecting pipe 402 has a threaded groove inside, it can increase the friction between the hose and the hose, and prevent the hose from coming loose during the air extraction process.

[0076] The process of using filter mechanism 4 to intercept larger particles in the gas:

[0077] As the gas enters the connecting pipe 402 through the hose, it then enters the fixed pipe 3. After being intercepted by the second filter plate 410, the third filter plate 411, and the first filter plate 407, larger particles of impurities remain between the first filter plate 407 and the third filter plate 411 or on the side of the third filter plate 411 away from the first filter plate 407, so as to prevent larger particles from entering the detection position and affecting the detection work.

[0078] By setting up a filter mechanism 4, the hose is connected by three fixed tubes 3 at different angles, an outer tube 401, and a connecting tube 402 to reduce the occurrence of hose bending. Furthermore, by creating a threaded groove inside the connecting tube 402, the friction between the connecting tube 402 and the hose is increased, thereby reinforcing the hose and preventing it from loosening. Since the three fixed tubes 3 are positioned in different directions, it is convenient for users to connect hoses in different directions, enabling in-situ detection of ozone concentration in multiple gases.

[0079] The regulating mechanism 6 also includes:

[0080] The fixed base 601 is installed inside the buffer box 5, and the first push rod 602 is installed on the fixed base 601;

[0081] Connector 603 is provided on the telescopic end of the first push rod 602;

[0082] An outer ring 607 is installed outside the moving tube 604 and is connected to the connector.

[0083] A connecting plate 608 is disposed on the side of the outer ring 607 away from the connector. The connecting plate 608 is made of magnetic material and can be magnetically attracted to the first sliding plate 11.

[0084] The fixed rod 605 and the limiting cylinder 606 connected to the fixed rod 605 are installed inside the buffer box 5. The limiting cylinder 606 is adapted to the moving tube 604, and the fixed rod 605 passes through the outer ring 607.

[0085] The working process of using the adjusting mechanism 6 to connect the fixed pipe 3 and the buffer box 5:

[0086] When the first push rod 602 is in the initial state, the moving tube 604 is in a position away from the connector 406 and is in the channel. At this time, the limiting cylinder 606 blocks the moving tube 604, and the gas cannot enter the buffer box 5 through the moving tube 604.

[0087] According to the direction of the gas containing the ozone concentration to be detected, the first push rod 602 corresponding to the fixed tube 3 is activated. The first push rod 602 drives the connector 603, outer ring 607, connecting plate 608 and moving tube 604 to move away from the limiting cylinder 606. The moving tube 604 gradually moves away from the limiting cylinder 606 and is outside the connector 406. At this time, the hose, fixed tube 3, connector 406 and moving tube 604 are connected. The gas enters the buffer box 5 through the gap between the moving tube 604 and the limiting cylinder 606. Since the height of the connecting tube 9 is lower than the height of the moving tube 604, the gas is gradually buffered and homogenized in the buffer box 5. Then the gas enters the detection box 7 through the connecting tube 9.

[0088] Adjusting the working process of filter mechanism 4 using adjustment mechanism 6:

[0089] During the movement of the connecting plate 608, under the action of magnetic force, the connecting plate 608 drives the first sliding plate 11 to slide inside the first sliding groove 10. The first sliding plate 11 drives the second sliding plate 13 to slide inside the second sliding groove 403 through the first telescopic rod 12. At this time, the first sliding plate 11 drives the first moving plate 404 and the second moving plate 405 to move. The first moving plate 404 moves in the first chamber, and the second moving plate 405 moves in the second chamber, thereby sealing and fixing the pipe 3 to prevent gas leakage.

[0090] During the movement of the second slide plate 13, the first filter plate 407, the second telescopic rod 409, the second filter plate 410, and the third filter plate 411 move accordingly, thereby adjusting the positions of the first filter plate 407, the second filter plate 410, and the third filter plate 411. In the process of controlling the movement of the three, the movement of impurities located between the first filter plate 407 and the second filter plate 410, and on the side of the second filter plate 410 away from the first filter plate 407, is promoted. This causes the particulate impurities accumulated between the filter plates to loosen, shift, or slide down, preventing impurities from staying in the same filtration position for a long time and causing blockage, thereby extending the continuous working time of the filtration mechanism 4.

[0091] By setting an adjustment mechanism 6, fixed limiting cylinders 606 are installed in the three moving tubes 604, which block the three moving tubes 604 in the initial state. According to the direction of ozone concentration detection, the corresponding first push rod 602 is adjusted, thereby controlling the moving tube 604 to connect with the corresponding connector 406, which facilitates gas entry while blocking the other two moving tubes 604 to prevent external gas from mixing into the buffer box 5 and affecting the detection results.

[0092] By setting up the filtration mechanism 4 and the adjustment mechanism 6, as the connecting plate 608 moves the first sliding plate 11 and the second sliding plate 13, the second sliding plate 13 moves the first filter plate 407, the second filter plate 410, and the third filter plate 411, thereby changing the relative positions of the multiple filter plates in the airflow channel and finely adjusting the filtration path through which the gas flows. When the filter plates move, the particles attached to them are vibrated and are more likely to fall off from the curved surface or the edge of the filter plate.

[0093] Working principle: Before using the equipment, select the location where ozone concentration needs to be measured. Attach one end of the flexible hose to the corresponding fixed pipe 3, and place the other end of the flexible hose at the location where ozone concentration needs to be measured. Connect one end of another flexible hose to the outside of the exhaust pipe 8, and place the other end at the exhaust position. Then, adjust the adjustment mechanism to adjust the connection between the corresponding fixed pipe 3 and the buffer box 5.

[0094] During the installation of the fixing pipe 3 and the hose, the hose is sleeved on the outside of the connecting pipe 402. Since the connecting pipe 402 has a threaded groove inside, it can increase the friction between the hose and the hose, and prevent the hose from coming loose during the air extraction process.

[0095] When the first push rod 602 is in the initial state, the moving tube 604 is in a position away from the connector 406 and is in the channel. At this time, the limiting cylinder 606 blocks the moving tube 604, and the gas cannot enter the buffer box 5 through the moving tube 604.

[0096] According to the direction of the gas with the ozone concentration to be detected, the first push rod 602 corresponding to the fixed tube 3 is activated. The first push rod 602 drives the connector 603, outer ring 607, connecting plate 608 and moving tube 604 to move away from the limiting cylinder 606. The moving tube 604 gradually moves away from the limiting cylinder 606 and is outside the connector 406. At this time, the hose, fixed tube 3, connector 406 and moving tube 604 are connected, and the gas enters the buffer box 5 through the gap between the moving tube 604 and the limiting cylinder 606.

[0097] Start the air pump in the test chamber 7. Under the action of gas suction, the gas enters the fixed pipe 3 through the hose, enters the buffer box 5 through the filter mechanism 4 in the fixed pipe 3, and enters the first working space inside the test chamber 7 through the connecting pipe 9 outside the buffer box 5.

[0098] During this process, as the gas enters the connecting pipe 402 through the hose, and then enters the fixed pipe 3 through the connecting pipe 402, after being intercepted by the second filter plate 410, the third filter plate 411, and the first filter plate 407, larger particles of impurities remain between the first filter plate 407 and the third filter plate 411 or on the side of the third filter plate 411 away from the first filter plate 407, so as to avoid larger particles entering the detection position and affecting the detection work.

[0099] Since the height of the connecting pipe 9 is lower than the height of the moving pipe 604, the gas is gradually buffered and homogenized in the buffer box 5, and then the gas enters the detection box 7 through the connecting pipe 9.

[0100] Ultraviolet light of a specific wavelength emitted by an ultraviolet lamp in the first working space passes through the gas flowing through it and is received by a probe on the other side. Ozone strongly absorbs this wavelength of ultraviolet light, so the probe can calculate the ozone concentration in the gas based on the degree of light intensity attenuation. The detector is then calibrated by comparing the ozone concentration with the reading of the detector at the location where the ozone concentration is to be detected. The gas that has passed through the first working space then enters the second working space through a suction pipe outside the first working space. After being treated by the ozone treatment equipment, the gas is discharged to the exhaust position through exhaust pipe 8.
