Technical Field

[0001] The present invention relates to the field of gas collection and detection, and in particular to negative pressure gas collection and detection equipment for high-altitude exhaust gas detection and a use method thereof. Background Art

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. This is especially true for chemical plants, steel mills, pharmaceutical plants, coking plants, and oil refineries, which emit strong odors that seriously pollute the environment and affect human health. Waste gas contains a wide variety of pollutants with complex physical and chemical properties and varying toxicity. Waste gas emitted from fuel combustion contains sulfur dioxide, nitrogen oxides, and hydrocarbons. Due to the different raw materials and processes used in industrial production, a variety of harmful gases and solid wastes are emitted, containing various components such as heavy metals, salts, and radioactive substances. High-altitude waste gas testing generally refers to the process of sampling and testing waste gas emitted into the air during industrial production.

[0003] A search revealed Chinese patent number CN220207206U, which discloses an environmental gas detection and collection device.

The device also comprises a motor mounted above the outer shell, the output end of the motor connected to a rotating rod, the upper end of which is mounted to a mounting plate, the lower side of which is mounted to a vacuum pump. A main gas collecting pipe is mounted below the end of the mounting plate, the lower side of which is connected to a fixing base, and a magnet a mounted inside the fixing base. The device is equipped with a collection chamber that can control the rotation of a suction head, adjust the relative position between magnet a and magnets b in different orientations, and utilize the attraction between the magnets to control the movement of a blocking ball, releasing the blockage of one blocking ball from the collection chamber. The lower ends of the remaining two collection chambers are sealed, allowing gas to be extracted and stored in separate chambers.

[0004] However, the above prior art has the following problems:

[0005] Although the positions of the collecting bin, magnet a, magnet b and other structures are used to utilize the attraction between the magnets to control the movement of the blocking balls, release the blockage of one of the blocking balls on the collecting tube, and the lower end openings of the other two collecting tubes are sealed to suck the gas, and the gas can be stored in separate bins to improve the diversity of sample collection and avoid mixing of the collected gases, it is impossible to filter the high-altitude gas during gas collection, which may cause impurities contained in the high-altitude exhaust gas to enter the interior of the detection equipment. After long-term use, debris accumulates inside the detection equipment, thereby affecting the normal use of the detection equipment.

[0022] The present invention also discloses a method for using a negative pressure gas collection and detection device for high-altitude exhaust gas detection, which comprises the following steps:

[0023] S1. By setting up an air pump, a negative pressure is formed inside the sealed mounting tube and the hollow cylinder, so that high-altitude exhaust gas is drawn into the mounting tube and the hollow cylinder through the air extraction pipe. The high-altitude exhaust gas is filtered by the filter plate, and then the filtered air is pumped into the diversion bottle through the connecting groove by the air extraction pump;

[0024] S2. After the air enters the diverter bottle, the air circulates through the flow pipe to allow the high-altitude exhaust gas to enter the connecting pipe. The electric valve controls the filtered high-altitude exhaust gas to enter the detection equipment, where the high-altitude exhaust gas is tested. The test data is then transmitted to the ground display through the control panel and transmission equipment.

[0025] S3. After the high-altitude exhaust gas detection is completed, the diversion motor is started, so that the rotating disk drives the flow slot to rotate, so that the flow slot is connected to other connecting slots and the diversion bottle. At the same time, the rotating motor is started, so that the driving gear drives the linkage gear to rotate, and drives the exhaust pipe to rotate, so as to extract the high-altitude exhaust gas at different positions, so that the high-altitude exhaust gas at different positions enters the interior of the diversion bottle at different positions, and finally the high-altitude exhaust gas at different positions is detected by the detection equipment;

[0026] S4. When the filter screen plate has been used for a long time, the adjusting motor is started, so that the rotating plate drives the second magnet block to rotate inside the mounting cylinder, so that the second magnet block is at the same horizontal line as the first magnet block. Through the magnetic force of the magnet block, the first magnet block moves and fits into the second magnet block, so that the scraping motor and the moving rod move, driving the rotating plate to fit into the filter screen plate to scrape the surface of the filter screen plate. When the rotating plate rotates, it synchronously drives the limit plate to rotate, so that the sewage ring rotates, drives the fixed cylinder to rotate, and causes the sewage plate to rotate, so that the baffle is separated from the collection cylinder. Through the setting of the scraping groove, the debris on the surface of the baffle is scraped off, so that the debris falls into the inner bottom wall of the collection cylinder. Through the conical setting of the inner bottom wall of the collection cylinder, the debris is discharged from the hollow cylinder through the sewage pipe;

[0027] S5. After the filter screen is scraped, the regulating motor is started to separate the second magnet block from the first magnet block. The scraping motor and the moving rod are reset by the setting of the elastic block, so that the rotating plate and the linkage plate are fitted together, driving the two scraping plates to rotate on the inner wall of the hollow cylinder to scrape the inner wall of the hollow cylinder.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Through the installation of the installation mechanism, the filtering mechanism, the diversion mechanism, the sealing mechanism, the scraping mechanism and the rotating mechanism, and through the mutual cooperation of the vacuum pump and the rotating mechanism, a negative pressure is formed inside the installation cylinder, thereby extracting the high-altitude exhaust gas. Through the setting of the filtering mechanism, the high-altitude exhaust gas entering the interior of the hollow cylinder is filtered, thereby preventing impurities in the high-altitude exhaust gas from entering the interior of the detection equipment and affecting the use of the detection equipment. Through the mutual cooperation of the connecting pipe and the air inlet pipe and other structures, the filtered high-altitude exhaust gas enters the interior of the detection equipment, thereby performing negative pressure gas collection and detection on the high-altitude exhaust gas. Through the setting of the detection mechanism, the detected data is transmitted to the external display, which is convenient for the staff to view the detection data;

[0030] 2. Through the installation mechanism, filtering mechanism, diversion mechanism, sealing mechanism, scraping mechanism and rotating mechanism, after the filter screen has been used for a long time, the regulating motor is started to move the second magnet block to the bottom of the first magnet block. The first magnet block is adsorbed on the second magnet block through magnetic force, so that the scraping motor and the moving rod move downward synchronously, so that the rotating plate fits the filter screen. The scraping motor is started to make the moving rod drive the rotating plate to rotate on the surface of the filter screen, so that the rotating plate cleans the debris on the surface of the filter screen, avoiding the staff from cleaning the filter screen. The jacking-up replacement makes the negative pressure gas collection and detection equipment for high-altitude exhaust gas detection more convenient to use, and the setting of the collection cylinder collects the debris at the cleaning location, avoiding the secondary impact of the debris on the filter screen. When the adjustment motor rotates, the limit plate is synchronously driven to rotate, thereby rotating the sewage ring, driving the baffle to separate from the collection cylinder, and through the setting of the scraping groove, the debris on the surface of the baffle is cleaned to the inner bottom wall of the collection cylinder. The conical setting of the inner bottom wall of the collection cylinder allows the debris to be discharged from the hollow cylinder through the sewage pipe, thereby completing the automatic discharge of the debris and facilitating the cleaning of the debris.

[0031] 3. Through the installation of the installation mechanism, the filtering mechanism, the diverting mechanism, the sealing mechanism, the scraping mechanism and the rotating mechanism, and through the setting of the diverter bottle, when the high-altitude exhaust gas is drawn into the interior of the installation cylinder by negative pressure, the high-altitude exhaust gas drawn at one time enters the interior of a diverter bottle through the mutual cooperation of the connecting groove and the circulation groove, and thus, through the setting of the circulation pipe, the high-altitude exhaust gas drawn into the interior of the diverter bottle enters the detection equipment for detection, and through the mutual cooperation of multiple diverter bottles and the adjustment mechanism, the exhaust pipe draws high-altitude exhaust gas at different positions and enters the interior of different diverter bottles, so that the detection equipment can detect different high-altitude exhaust gases at different positions, thereby obtaining more data, facilitating comparison for staff, and thus improving the accuracy of the detection equipment for high-altitude exhaust gas detection;

[0032] 4. Through the structural settings of the installation mechanism, filtering mechanism, diversion mechanism, sealing mechanism, scraping mechanism and rotating mechanism, and through the settings of the installation cylinder and the hollow cylinder, the installation bolts are removed to disengage the hollow cylinder from the threaded block, thereby disengaging the sealing airbag from the installation groove, and thus disengaging the hollow cylinder from the installation cylinder. After that, by rotating the bolt on the first magnet block, not only the first magnet block no longer limits the filter screen, but also the filter screen is disengaged from the hollow cylinder, making the filter screen replacement more convenient, and making it easier for the staff to clean the debris inside the collection cylinder, thereby making the negative pressure gas collection and detection equipment for high-altitude exhaust gas detection more convenient to use. At the same time, through the setting of the sealing mechanism, the airtightness of the hollow cylinder and the installation cylinder is better when installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In this embodiment: after the detection mechanism 7 detects the high-altitude exhaust gas inside one of the diverter bottles 306, the rotating motor 803 is started, so that its output end drives the driving gear 804 to rotate, thereby causing the linkage gear 805 to engage and rotate, driving the exhaust pipe 802 to rotate on the mounting base 801, so that the exhaust pump 104 is set, so that the exhaust pipe 802 can extract high-altitude exhaust gas at different positions, and then through the setting of the diverter mechanism 3, the detection mechanism 7 detects different high-altitude exhaust gases, so that multiple detection data can be obtained, so that the staff can detect the high-altitude exhaust gas more accurately;

[0059] In this embodiment, when it is necessary to scrape and clean the surface of the filter screen 203, the regulating motor 501 is started, and its output end drives the rotating rod 504 to rotate, thereby driving the rotating plate 502 to rotate synchronously, so that the second magnet block 503 rotates synchronously, so that the second magnet block 503 and the first magnet block 206 are on the same horizontal line, and the magnetic force of the second magnet block 503 is greater than the elastic force of the elastic block 208, so that the magnetic force of the second magnet block 503 causes the first magnet block 206 to move downward, so that the first magnet block 206 and the second magnet block 503 are aligned. The scraping motor 209 is in contact with each other, and the moving rod 205 and the scraping motor 209 are synchronously driven to move downward, thereby causing the rotating plate 404 to move downward synchronously, so that the rotating plate 404 is in contact with the filter screen plate 203. Then, the scraping motor 209 is started, and its output end drives the moving rod 205 to rotate, so that the rotating plate 404 rotates synchronously on the surface of the filter screen plate 203, thereby cleaning the surface of the filter screen plate 203 through the rotating plate 404, avoiding the influence of impurities on the filter screen plate 203, and driving the sewage discharge ring 212 to rotate through the setting of the limit plate 505;

[0060] Please refer to Figures 1 and 2The detection mechanism 7 includes a detection device 701 fixedly connected to the other side of the upper surface of the supporting base plate 101, one side of the detection device 701 is fixedly connected to a connecting pipe 702 connected to the mounting cylinder 102, the connecting pipe 702 is connected to the flow pipe 308, the surface of the connecting pipe 702 is fixedly connected to an electric valve 703, the upper surface of the detection device 701 is fixedly connected to a control board 704 electrically connected to the detection device 701 through a wire, and one side of the upper surface of the detection device 701 is fixedly connected to a transmission device 705 electrically connected to the detection device 701 through a wire.

[0061] In this embodiment, the electric valve 703 is activated to connect the connecting pipe 702 with the flow pipe 308, thereby allowing the filtered high-altitude exhaust gas to enter the interior of the detection device 701 to detect the high-altitude exhaust gas. At the same time, the control panel 704 and the transmission device 705 cooperate with each other to transmit the detected data to the display, making it convenient for the staff to view the detection data.

[0063] In this embodiment, when the hollow cylinder 202 is installed with the mounting cylinder 102, the sealing airbag 601 is inserted into the interior of the mounting groove 603. The setting of the tightening ring 602 compresses the sealing airbag 601, causing the sealing airbag 601 to deform and thus fit against the inner wall of the mounting groove 603, thereby achieving a sealing effect.

[0064] The following provides a method for using the negative pressure gas collection and detection device for high-altitude exhaust gas detection in combination with the above-mentioned negative pressure gas collection and detection device for high-altitude exhaust gas detection, which specifically includes the following steps:

[0065] S1. The air pump 104 is provided to create a negative pressure inside the sealed mounting tube 102 and the hollow cylinder 202. As a result, the high-altitude exhaust gas is drawn into the mounting tube 102 and the hollow cylinder 202 through the air extraction pipe 802. The high-altitude exhaust gas is filtered by the filter screen 203. The filtered air is then passed through the connecting groove 305 and into the diverter bottle 306 by the air pump 104.

[0066] S2. After air enters the diverter bottle 306, the air circulates through the flow pipe 308 and enters the connecting pipe 702. The electric valve 703 controls the filtered high-altitude exhaust gas to enter the detection device 701, where the high-altitude exhaust gas is detected. The detection data is transmitted to the ground display through the settings of the control panel 704 and the transmission device 705.

[0067] S3. After the high-altitude exhaust gas detection is completed, the diversion motor 302 is started, causing the rotating disk 303 to drive the circulation slot 304 to rotate, so that the circulation slot 304 is connected to the other connecting slots 305 and the diversion bottle 306. At the same time, the rotating motor 803 is started, so that the driving gear 804 drives the linkage gear 805 to rotate, and drives the exhaust pipe 802 to rotate, so that the high-altitude exhaust gas at different positions is extracted, so that the high-altitude exhaust gas at different positions enters the interior of the diversion bottle 306 at different positions, and finally the high-altitude exhaust gas at different positions is detected by the detection device 701;

[0068] S4. After the filter screen 203 has been used for a long time, the regulating motor 501 is started, so that the rotating plate 502 drives the second magnet block 503 to rotate inside the mounting cylinder 102, so that the second magnet block 503 and the first magnet block 206 are on the same horizontal line. The magnetic force of the magnet blocks causes the first magnet block 206 to move and fit with the second magnet block 503, thereby causing the scraping motor 209 and the moving rod 205 to move, driving the rotating plate 404 to fit with the filter screen 203, and adjusting the filter screen 203. 3. When the rotating plate 502 rotates, the limiting plate 505 is synchronously driven to rotate, so that the sewage ring 212 rotates, and the fixed cylinder 210 rotates, so that the sewage plate 213 rotates, thereby separating the baffle 214 from the collecting cylinder 204. The scraping groove 216 is provided to scrape the debris on the surface of the baffle 214, so that the debris falls into the inner bottom wall of the collecting cylinder 204. The conical setting of the inner bottom wall of the collecting cylinder 204 allows the debris to be discharged from the hollow cylinder 202 through the sewage pipe 215.

[0069] S5. After the filter plate 203 is scraped, the regulating motor 501 is started to separate the second magnet block 503 from the first magnet block 206. The scraping motor 209 and the moving rod 205 are reset through the setting of the elastic block 208, so that the rotating plate 404 and the linkage plate 403 are in contact with each other, driving the two scraping plates 402 to rotate on the inner wall of the hollow cylinder 202 to scrape the inner wall of the hollow cylinder 202.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
