Description

Technical Field

[0001] This application relates to the technical field of monitoring devices, and particularly to laboratory environment monitoring devices. Background Art

[0002] A large number of highly purified chemical substances are often stored in laboratories. If these substances are stored or operated improperly, they are likely to be dangerous, especially the generation of toxic gases. If not discovered in time, it may endanger the lives of experimental personnel. Currently, the harmful gas monitoring devices on the market are all connected to the ventilation ducts of laboratories, which are far from the experimental tables. When trace amounts of harmful gases are generated, it is easier for them to be inhaled by experimental personnel rather than detected by the monitors.

[0003] The patent document with the application number 202320661352.6 discloses an indoor environment monitoring and treatment device in a laboratory, including an experimental table. An air hood is placed above the experimental table. A baffle is connected to the side of the air hood. The baffle is provided with an installation hole, and a long-sleeved glove is connected to the installation hole. A material door is connected to the side of the air hood. An air inlet pipe is connected to the side of the air hood. The air inlet pipe is connected to an air extractor. A first air outlet pipe is connected to the top of the air hood. For this indoor environment monitoring and treatment device in the laboratory, the gas is collected by the air hood and sent into the air channel for analysis, and processed by the PLC controller to achieve the monitoring and treatment of the indoor environment in the laboratory. The air is inhaled into the air hood by the air extractor, and at the same time, the air in the air hood is pushed into the air channel for detection to achieve the one-way flow of gas. By setting a material door on the side of the air hood, the experimental equipment and supplies in the air hood can be replaced according to needs during use.

Detailed implementation manners

[0021] The following will further elaborate on this application in conjunction with the Figures 1-3 drawings.

[0022] An embodiment of this application discloses a laboratory environmental monitoring device. Referring to Figures 1-3 , the laboratory environmental monitoring device includes a device body 1. A controller 2 is arranged on the outer side of the device body 1, and an air purification mechanism is arranged inside the device body 1. Two one-way interception components are arranged on the air purification mechanism; the one-way interception component includes a connection shell 8. A sealing ring 9 is fixedly connected to the inner side of the connection shell 8. A baffle 10 is hinged to the outer side of the sealing ring 9. The sealing ring 9 and the baffle 10 are arranged in a cylindrical structure; a sealed state is formed between the sealing ring 9 and the baffle 10 to prevent the reflux of gas.

[0023] Referring to Figures 1-3 , the air purification mechanism includes a suction fan 6. The suction fan 6 is arranged at the rear side inside the device body 1. The air outlet end of the suction fan 6 is provided with a first input pipe 7, and the air outlet end of the suction fan 6 is communicated with the first input pipe 7. One one-way interception component is arranged at one end of the first input pipe 7.

[0024] Referring to Figures 1-3, one end of the one-way intercepting component away from the first input pipe 7 is communicated with a filter box 11. A plurality of activated carbon layers 12 are installed inside the filter box 11. One side of the filter box 11 away from the first input pipe 7 is communicated with a purification chamber 13. A gas sensor 14 is arranged on the purification chamber 13, and the probe of the gas sensor 14 extends to the inside of the purification chamber 13. A reflux pipe 15 is arranged at the top of the purification chamber 13, and a first valve is installed at the connection between the purification chamber 13 and the reflux pipe 15. A one-way intercepting component is arranged on the reflux pipe 15. An exhaust pipe 16 is arranged on one side of the purification chamber 13 away from the filter box 11, and a second valve is arranged at the connection between the purification chamber 13 and the exhaust pipe 16; the second valve and the first valve are electrically connected to the controller 2, and this belongs to the prior art and will not be elaborated here.

[0025] Refer to Figures 1-3 , an observation window 3 is installed on the front side of the device body 1. The observation window 3 is connected with an operation area 5 through two hinges 4. Two operation holes are opened on the outer side of the operation area 5, and rubber sleeves are hermetically connected to the inner sides of the operation holes; rubber sleeves are hermetically connected to the inner sides of the operation area 5, and the staff can operate through the rubber sleeves to avoid the outflow of gas; the gas pushes the air in front into the first input pipe 7 through the first input pipe 7, and then the air pushes up the baffle 10 and enters the inside of the filter box 11, and is filtered through a plurality of activated carbon layers 12. For waste gas containing substances such as organic solvents and oils, adsorbents such as activated carbon are used for adsorption treatment. Since the gas sensor 14 and the signal receiver are connected by a wire, and the signal receiver and the controller 2 are connected by a wire, when harmful gas is detected in the purification chamber 13 and the gas sensor 14, it is detected by the air sensor, and the result is transmitted to the signal receiver, and the signal receiver sends it to the controller 2 for processing. The controller 2 displays the gas detection result on the display screen. When the gas does not meet the standard, the first valve is opened for reflux to perform secondary treatment on the gas until the gas meets the preset standard and the second valve is opened to discharge the gas. Through targeted treatment technology, effective purification and resource recovery of waste gas are realized.

[0026] The implementation principle of the laboratory environment monitoring device in the embodiments of this application is as follows: When in use, open the operation area 5 to place the equipment and supplies required for the experiment, close the operation area 5, turn on the suction fan 6 through the controller 2, and put both hands into the rubber sleeves through the installation holes to conduct the experiment. The suction fan 6 sends air into the first input pipe 7, and at the same time, the gas generated behind pushes the air in front into the first input pipe 7 through the first input pipe 7, and then the air lifts the baffle 10 and enters the inside of the filter box 11, and is filtered through multiple activated carbon layers 12. For waste gas containing substances such as organic solvents and oils, adsorbents such as activated carbon are used for adsorption treatment. Since the gas sensor 14 and the signal receiver are connected by a wire, and the signal receiver and the controller 2 are connected by a wire, when harmful gases are detected in the purification chamber 13 and the gas sensor 14, they are detected by the air sensor, and the results are transmitted to the signal receiver, and the signal receiver sends them to the controller 2 for processing. The controller 2 displays the gas detection results on the display screen. When the gas does not meet the standard, open the first valve for reflux and conduct secondary treatment on the gas until the gas meets the preset standard and then open the second valve to discharge the gas. Through targeted treatment technology, the effective purification of waste gas is realized, and environmental pollution is reduced;

[0027] The one-way interception component enables the gas to flow unidirectionally, avoiding the reflux of air and affecting the detection results; realizing the real-time monitoring and automatic treatment of waste gas and improving the treatment efficiency.
