Description

Technical Field

[0001] The present invention relates to the technical field of gas detection equipment, and more specifically to a balanced exhaust gas online detection device for barbell production. Background Art

[0002] During the production and processing of barbell bars, machine tools are required for turning, and robots or friction welders are required for welding, which may generate waste gas. Therefore, a gas online detection device is needed to detect and monitor the waste gas. On the one hand, it ensures a good working environment and avoids affecting the health of workers; on the other hand, it also prevents waste gas from affecting the atmospheric environment.

[0003] The existing gas online detection equipment consists of a gas sampling mechanism, a host, a data analysis mechanism, and a data storage mechanism. The unstable air gas is sampled through the sampling mechanism and then transmitted to the data analysis mechanism in the host. The data analysis mechanism analyzes and processes the data intelligently to form a histogram of the composition and content of the air. The data is then stored through the storage mechanism and transmitted to a mobile phone, computer or printer for printing.

[0004] The sampling mechanism includes a pump-suction sampling air inlet and a filter. The filter is used to filter the water vapor and dust carried by the air. On the one hand, it prolongs the service life of the internal components, and on the other hand, it improves the detection accuracy. However, since the gas online detection equipment needs to perform real-time gas detection 24 hours a day to prevent enterprises from secretly discharging, the filter needs to be replaced in time. It is troublesome for personnel to replace it, and it is easy to forget to replace it, which will cause the data analysis structure of the gas online detection equipment to fluctuate greatly, resulting in distorted measurement results.

[0005] In addition, the waterproof system of the host is poor and it is not easy to be exposed to the open air environment, which will make the use of the gas online detection equipment too limited.

[0037] The base 1 includes a bottom groove 102, a lifting rod 101 is movably sleeved on the top of the inner wall of the bottom groove 102, the top surface of the lifting rod 101 is fixedly connected to the bottom surface of the main unit 201, and a chassis 104 is fixedly connected to the bottom of the outer wall of the bottom groove 102.

[0043] In this embodiment, it should be specifically explained that a hole groove adapted to the humidity sensor 2026 is provided at the bottom of the inner wall of one side of the tube 301, so that the humidity sensor 2026 can be inserted into the tube 301 along the hole groove, and one side of the humidity sensor 2026 is close to one side of the core changing mechanism 3, so as to facilitate real-time detection of the amount of water vapor absorbed by the core changing mechanism 3;

[0044] Through holes compatible with one side of the pump-suction nozzle 4 are opened on both sides of the bottom of the tube 301, and the first magnetic induction mechanism 2025 and the pump-suction nozzle 4 are respectively located on the left and right sides of the through holes. The area of ​​the through hole on the side of the tube 301 close to the first magnetic induction mechanism 2025 is larger than the area of ​​the through hole on the side of the tube 301 close to the pump-suction nozzle 4. The first magnetic induction mechanism 2025 occupies the upper part of the through hole on one side of the tube 301, and the bottom of the through hole on one side of the tube 301 is set as an air channel.

[0045] Reference Figure 5-7 The first magnetic induction mechanism 2025 includes a protective cover 20251 , the interior of the protective cover 20251 is movably connected to a first iron tube 20252 , and the surface of the first iron tube 20252 is movably connected to a first coil 20253 .

[0046] The filter disc 302 comprises a casing 3021 , a cotton core 3022 is fixedly sleeved on one side of the inner wall of the casing 3021 , and an iron sheet 3023 is fixedly sleeved on the other side of the top of the inner wall of the casing 3021 .

[0047] The controller 2024 includes a control box 20241, a telescopic rod 20242 is fixedly sleeved on the bottom of one side of the control box 20241, a grinding plate 20243 is fixedly connected to the top of one side of the control box 20241, a slider 20244 is fixedly connected to the top of the telescopic rod 20242, rollers 20245 are movably sleeved on both sides of the slider 20244 through a rotating shaft, both sides of the inner wall of the middle part of the slider 20244 are movably sleeved with the telescopic rod 20242 through a rotating shaft, and a groove matching the slider 20244 and the roller 20245 is provided at the bottom of the grinding plate 20243.

[0048] In this real-time example, it should be specifically explained that the side of the push plate 20243 close to the pump suction nozzle 4 is movably connected to the bottom surface of one side of the pipe 301 through a hinge;

[0049] The slider 20244 slides along the groove at the bottom of the push plate 20243. When the roller 20245 is lifted to the maximum length, the roller 20245 pushes the slider 20244 to the side of the inner wall of the groove close to the pump suction nozzle 4. At this time, the push plate 20243 is pressed against the bottom surface of the pipe 301. When the roller 20245 is fully retracted, the slider 20244 slides to the side of the inner wall of the groove close to the control box 20241. At this time, the push plate 20243 rotates downward at an angle of 30 degrees along the hinge, which is convenient for the filter 302 to flow out and the outflow speed is controllable.

[0050] The extension length of the telescopic rod 20242 pushed out by the control box 20241 is affected by the circuit current. Specifically, it continuously retracts as the circuit current decreases, and continuously lifts up when the circuit current increases. The lifting speed of the telescopic rod 20242 is also related to the current change speed. Specifically, when the circuit current increases rapidly, the telescopic rod 20242 is lifted up rapidly.

[0051] Reference Figure 8-9 The second magnetic induction mechanism 5 comprises a second iron tube 501, and a second coil 502 is movably sleeved on the outer surface of the second iron tube 501;

[0054] In this real-time example, it should be specifically explained that the magnetic poles of the induced magnetic force generated by the magnetic sheet 601 and the second iron tube 501 are opposite, and the opposite magnetic poles have a repulsive force, which pushes the magnetic sheet 601. The current size affects the induced electromagnetic size, and then affects the repulsive force.

[0055] Reference Fig.10 , the positive electrode of the power supply 2021 is connected to the input end of the button 2012, the output end of the button 2012 is connected to the input end of the humidity detector 2023, the output end of the humidity detector 2023 is connected to the input end of the controller 2024, the output end of the controller 2024 is connected to the input end of the variable resistor 2022, the input end of the variable resistor 2022 is connected to the input end of the first coil 20253, and the output end of the first coil 20253 is connected to the negative electrode of the power supply 2021;

[0057] Working principle of the present invention:

[0058] First, the first group of circuits includes a variable resistor 2022, a humidity detector 2023, a controller 2024 and a first magnetic induction mechanism 2025 which are sequentially connected and connected in series at both ends of a power source 2021, the second group of circuits includes a second magnetic induction mechanism 5 and a protection resistor which are sequentially connected and connected in parallel at both ends of the first group of circuits, and the third group of circuits includes a second switch control key 2014, a buzzer 2018 and an alarm 2019 which are sequentially connected and connected in parallel at both ends of the second group of circuits;

[0059] Secondly, adjust the height of the device, place the chassis 104 on a predetermined horizontal ground, manually pull out the limit rod 103 inserted into the limit groove on one side of the bottom groove 102, and then pull up or push down the lifting rod 101, the lifting rod 101 slides on the inner wall of the bottom groove 102, and further inserts the limit rod 103 into the limit groove on one side of the bottom groove 102, thereby achieving the stability of the device;

[0060] Next, the first switch control key 2013 is pressed, and the second circuit group and the third circuit group operate normally. The circuit is in a conductive state, and the current flows out from the positive pole of the power supply 2021, enters the protective resistor, and then flows from the protective resistor into the second coil 502, and then flows back from the second coil 502 into the negative pole of the power supply 2021, and then generates an induced magnetic field around the second magnetic induction mechanism 5, and then the magnetic force repels the magnetic sheet 601 with the opposite magnetic pole, and then the magnetic sheet 601 pushes the spring tube 602 to open the shed frame 603 upward, and then the shed frame 603 opens the shed surface 604;

[0061] Next, by pressing the button 2012, the first group of circuits operates normally, and the circuit is in a pass state. The current flows out from the positive electrode of the power supply 2021 into the humidity detector 2023, and then flows into the variable resistor 2022 from the humidity detector 2023, and then flows into the first magnetic induction mechanism 2025 from the variable resistor 2022, and flows back into the negative electrode of the power supply 2021 from the first magnetic induction mechanism 2025. The humidity of the cotton core 3022 is detected by the humidity sensor 2026 on one side of the humidity detector 2023. As the water absorption of the cotton core 3022 continues to increase, the detection value of the humidity sensor 2026 continues to increase, and the variable resistor 2022 will adjust the self-generated resistance value to increase continuously until it reaches the internal resistance threshold of the variable resistor 2022. At this time, the circuit current is minimum. The electromagnetic induction generated by the first magnetic induction mechanism 2025 is difficult to adsorb the filter 302. At the same time, the circuit current reaches the threshold value set by the controller 2024. The control box 20241 further controls the telescopic rod 20242 to retract, and then the telescopic rod 20242 pulls the slider 20244 to slide along the bottom groove of the grinding push plate 20243 to the side close to the control box 20241. At this time, the roller 20245 rolls along the inner wall of the groove of the grinding push plate 20243, and then the grinding push plate 20243 rotates 30 degrees along the bottom side of the pipe 301 through the hinge, and then the filter 302 falls under the influence of gravity, and then flows out along the angle gap formed by the pipe 301 and the grinding push plate 20243, and then the top filter 302 falls to the original filter 302 position;

[0062] Finally, the exhaust gas from the factory continues to enter from the pump suction nozzle 4, further absorbs water and dust through the cotton core 3022, and then enters the main unit 201, and the inhaled gas is detected and analyzed by the data analysis agency, and finally a histogram of the composition and content of the air is formed on the second switch control button 2014, which is broadcasted through the buzzer 2018. If the standard is exceeded, the alarm 2019 will sound an alarm.
