Description

Technical Field

[0001] This utility model belongs to the field of toxic gas monitoring technology in chemical industrial parks, specifically a user-friendly toxic gas monitoring device for chemical industrial parks. Background Technology

[0002] With the booming development of the chemical industry, chemical industrial parks, as important carriers of chemical production, storage, and transportation, face severe risks of toxic gas leaks while promoting economic development. To ensure personnel safety and maintain ecological stability, toxic gas monitoring devices have become key equipment in the safety management system of chemical industrial parks. Currently, most commercially available toxic gas monitoring devices for chemical industrial parks focus on gas concentration detection, real-time data transmission, and alarm functions. They identify and monitor target toxic gases through sensors, then feed the data back to the control terminal. Once the toxic gas concentration exceeds the standard, the alarm system is triggered.

[0003] Meanwhile, the announcement number CN216285162U, entitled "A Toxic Gas Monitoring Device for Easy Detection," describes a device that includes a support plate. Bolts are movably connected to all four sides of the front end of the support plate. A detection box is fixedly connected to the center of the front end of the support plate, and a controller is located at the center of the front end of the detection box. A buzzer is fixedly connected to the right side of the detection box. Through the combined use of a blower motor, a blower rod, and a blower fan, the blower motor drives the blower rod to rotate, thereby drawing air from the bottom of the device into the detection box. The sensor plate detects the air drawn in by the blower fan. The buzzer and warning light work together so that when the sensor plate detects toxic gas, the buzzer sounds an alarm, and the warning light emits a red light, allowing staff to quickly identify the problem and improving the device's practicality.

[0004] However, the device lacks gas filtration and processing capabilities. In practical applications, the gas composition in chemical industrial parks is complex and variable. In addition to the target toxic gas, it may also contain a large number of dust particles and other interfering substances. These impurities will not only adhere to the surface of the gas sensor, affecting the sensor's sensitivity and detection accuracy, but also cause deviations or even false alarms in the detection data, shortening the sensor's lifespan and increasing equipment maintenance costs.

[0005] Moreover, the direct emission of untreated mixed gases containing toxic gases can cause secondary pollution to the surrounding environment, especially in chemical production workshops or storage areas with poor ventilation.

[0006] Therefore, a user-friendly toxic gas monitoring device for chemical industrial parks is proposed to address the above-mentioned problems. Utility Model Content

[0007] To address the problems mentioned in the background art, this utility model provides an easy-to-use toxic gas monitoring device for chemical industrial parks. It has the advantage of being able to filter inhaled gases, thus treating dust particles and other substances and preventing impurities from adhering to the sensor and affecting its normal operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a toxic gas monitoring device for easy use in chemical industrial parks, comprising an installation plate, a connecting pipe installed on the surface of the installation plate, a suction mechanism installed on the surface of the installation plate, an output pipe of the suction mechanism connected to the connecting pipe, and an impurity filter assembly installed on the surface of the connecting pipe;

[0009] The impurity filtration assembly includes a processing tube, one end of which is connected to the connecting tube. A filter disc is inserted inside the processing tube. Fixing plates are symmetrically mounted on the surface of the processing tube. A connecting plate is mounted on the surface of the filter disc and is inserted between the two fixing plates. One end of the processing tube is connected to a detection tube. Support plates are symmetrically mounted inside the detection tube. Multiple sensors are distributed on the side of the two support plates that are close to each other. A replacement assembly is mounted on the surface of the processing tube.

[0010] Preferably, the surface of the mounting plate has multiple mounting holes, which facilitates fixing the mounting plate to a suitable location within the chemical industrial park using bolts.

[0011] Preferably, the filter disc has a multi-layer composite structure, consisting of a coarse filter layer, an activated carbon adsorption layer, and a high-efficiency filter membrane layer arranged sequentially.

[0012] Preferably, a diffuser plate is installed at the outlet end of the detection tube.

[0013] Preferably, sealing strips are symmetrically installed on the surface of the connecting plate, and the sealing strips are in contact with the processing tube.

[0014] Preferably, the replacement component includes an adjusting block, which is slidably connected in a cavity inside the fixed plate. A strip is symmetrically installed on the side surface of the adjusting block near the connecting plate. One end of the strip passes through the fixed plate and is inserted into a slot on the surface of the connecting plate. A pull rod is slidably connected in a through hole on the surface of the fixed plate. One end of the pull rod passes through the fixed plate and is connected to the adjusting block.

[0015] Preferably, a return spring is sleeved on the surface of the pull rod, one end of the return spring is connected to the pull rod, and the other end of the return spring is installed inside the fixed plate.

[0018] 2. This utility model, by setting up a replacement component and through the linkage design of the pull rod, adjusting block and insert, enables quick disassembly and assembly of the filter disc. The staff only needs to pull the pull rod to release the fixation, without the need for complicated tools or professional skills, which greatly shortens the maintenance time and improves work efficiency.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5As shown, this utility model provides a toxic gas monitoring device that is easy to use in chemical industrial parks, including a mounting plate 1, a connecting pipe 12 mounted on the surface of the mounting plate 1, a suction mechanism 13 mounted on the surface of the mounting plate 1, the output pipe of the suction mechanism 13 being connected to the connecting pipe 12, and an impurity filter assembly 2 mounted on the surface of the connecting pipe 12.

[0027] The impurity filtration assembly 2 includes a processing tube 23. One end of the connecting tube 12 is connected to the processing tube 23. A filter disc 24 is inserted inside the processing tube 23. Fixing plates 25 are symmetrically installed on the surface of the processing tube 23. A connecting plate 26 is installed on the surface of the filter disc 24 and is inserted between the two fixing plates 25. One end of the processing tube 23 is connected to a detection tube 211. Support plates 21 are symmetrically installed inside the detection tube 211. Multiple sensors 22 are distributed on the side of the two support plates 21 that are close to each other. A replacement assembly 3 is installed on the surface of the processing tube 23. The assembly can sequentially intercept large particulate impurities, adsorb harmful gas molecules, and filter small particles, effectively preventing impurities from adhering to the surface of the sensors 22, reducing detection errors or false alarms caused by impurity interference, and significantly improving the accuracy and stability of toxic gas concentration detection.

[0028] Specifically, the surface of the mounting plate 1 has multiple mounting holes, which facilitates fixing the mounting plate 1 to a suitable location within the chemical industrial park using bolts.

[0029] like Figures 1 to 5 As shown, the filter disc 24 has a multi-layer composite structure, consisting of a coarse filter layer, an activated carbon adsorption layer, and a high-efficiency filter membrane layer, which can efficiently filter the gas.

[0030] Furthermore, a diffuser plate 29 is installed at the outlet end of the detection tube 211 to facilitate the diffusion and outflow of the detected gas.

[0031] It is worth noting that sealing strips 210 are symmetrically installed on the surface of the connecting plate 26. The sealing strips 210 fit into the processing tube 23, so that the processing tube 23 can be sealed.

[0032] like Figures 1 to 5 As shown, the replacement component 3 includes an adjusting block 31. The adjusting block 31 is slidably connected in the cavity inside the fixing plate 25. A strip 32 is symmetrically installed on the side surface of the adjusting block 31 near the connecting plate 26. One end of the strip 32 passes through the fixing plate 25 and is inserted into the slot on the surface of the connecting plate 26. A pull rod 33 is slidably connected in the through hole on the surface of the fixing plate 25. One end of the pull rod 33 passes through the fixing plate 25 and is connected to the adjusting block 31. Through the linkage design of the pull rod 33, the adjusting block 31 and the strip 32, the filter disc 24 can be quickly disassembled and assembled. The operator only needs to pull the pull rod 33 to release the fixation. No complicated tools or professional skills are required, which greatly shortens the maintenance time and improves work efficiency.

[0033] It is worth emphasizing that a return spring 34 is sleeved on the surface of the pull rod 33. One end of the return spring 34 is connected to the pull rod 33, and the other end of the return spring 34 is installed inside the fixed plate 25, which makes it convenient for operators to use.

[0034] The structures such as the suction mechanism 13 and the sensor 22 are existing technologies and have the same working principle as the prior art, which is the same as the prior art patent, application number CN216285162U, "A Toxic Gas Monitoring Device for Easy Detection". For details, please refer to the prior art patent.

[0035] Working principle and process: The device is fixed to the area to be monitored in the chemical industrial park using bolts through the mounting holes on the surface of the mounting plate 1. The suction mechanism 13 is started, and the air pump inside the suction mechanism 13 starts to work, drawing the gas in the surrounding environment into the connecting pipe 12 through the output pipe, forming a stable gas flow path to ensure that the gas to be detected can continuously enter the device.

[0036] After the mixed gas containing toxic gases enters the processing tube 23 along the connecting pipe 12, it first passes through the filter plate 24. The multi-layer composite structure of the filter plate 24 plays a role: the coarse filter layer intercepts larger particulate impurities in the gas, and the activated carbon adsorbs odor substances and some harmful gas molecules in the gas using its adsorption properties; the high-efficiency filter membrane layer further filters out small particles and residual impurities, ensuring that the gas entering the subsequent detection stage is purer and reducing the interference of impurities on the sensor 22.

[0037] The sealing strip 210 fits snugly against the processing tube 23, thus sealing the processing tube 23 and preventing gas leakage.

[0038] After filtration, the gas enters the detection tube 211 from the processing tube 23. As the gas flows within the detection tube 211, multiple sensors 22 distributed on the two support plates 21 begin to operate. The sensors 22 can accurately identify and detect the type and concentration of the target toxic gas; for details, please refer to the prior art.

[0039] The gas that has been tested is discharged through the diffuser plate 29 at the outlet end of the test tube 211, so that the gas is evenly diffused and discharged, avoiding excessively high local gas concentration and reducing the impact on the surrounding environment.

[0040] After the filter disc 24 has been used for a period of time, its filtration efficiency decreases, requiring replacement. Pulling the lever 33 causes the adjusting block 31 to slide within the cavity of the fixed plate 25, allowing the insert 32 to be pulled out of the slot in the connecting plate 26, overcoming the spring force of the return spring 34. At this point, the filter disc 24 can be removed from the treatment tube 23 and replaced with a new one. Inserting the connecting plate 26 of the new filter disc 24 between the two fixed plates 25 and releasing the lever 33 causes the adjusting block 31 to re-insert the insert 32 into the slot in the connecting plate 26 under the action of the return spring 34, completing the quick replacement of the filter disc 24 and ensuring the continuous and stable operation of the device.
