Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to a device for online monitoring and early warning of volatile organic waste gas. Background Art

[0002] In the common sense, VOC refers to volatile organic compounds. According to the definition of the World Health Organization, VOC refers to compounds with a boiling point of 50℃-250℃, a saturated vapor pressure of more than 133.32KPa at room temperature, and a type of organic matter that exists in the air in the form of vapor at room temperature; however, in the environmental sense, it refers to a type of active volatile organic compound, that is, a type of volatile organic compound that can cause harm. Volatile organic waste gas needs to be monitored online and warned.

[0003] For example, the device for online monitoring and early warning of volatile organic waste gas with the authorization announcement number "CN217211798U" changes the position of the first warning rod. People can judge whether the filter needs to be replaced by observing the position of the first warning rod, so as to avoid the detection structure being affected by the untimely replacement of the filter. However, after a long period of operation, a large amount of dust will accumulate on the surface of the filter for the device for online monitoring and early warning of volatile organic waste gas, blocking the flow of gas, which results in a slower gas passage speed, thus reducing the working efficiency of the device for online monitoring and early warning. At the same time, after the water absorption plate fully absorbs the moisture in the gas, the device for online monitoring and early warning of volatile organic waste gas cannot discharge the moisture in the water absorption plate. When the water absorption plate is saturated with water, it cannot be discharged in time, which causes the water absorption plate to fail, thus reducing the working quality of the device for online monitoring and early warning. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that after working for a long time, a large amount of dust will accumulate on the surface of the filter screen, blocking the gas circulation, which leads to a slower gas passage speed, thus reducing the working efficiency of the online monitoring and early warning device and the inability to discharge the moisture in the water absorption plate after the water absorption plate fully absorbs the moisture in the gas. When the water absorption plate is saturated with water, it cannot be discharged in time, which leads to failure of the water absorption plate, thus reducing the working quality of the online monitoring and early warning device. A device for online monitoring and early warning of volatile organic waste gas is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for online monitoring and early warning of volatile organic waste gas is designed, including a detection cabinet, a filter knocking mechanism is provided inside the detection cabinet, a water absorption plate fixing mechanism is provided inside the detection cabinet, the interior of the detection cabinet is slidably engaged with the filter, the outer wall of the detection cabinet is fixedly connected to the wind gathering hood, the inner wall of the detection cabinet is fixedly connected to the motor through a bracket, the output shaft of the motor is fixedly connected to the exhaust fan, and the outer wall of the detection cabinet is slidably connected to the water absorption plate through a through hole.

[0007] Preferably, the filter knocking mechanism includes a first knob, the outer wall of the first knob is adjacent to the detection cabinet, the outer wall of the first knob is fixedly connected to the cam, the outer wall of the cam is fitted with the push plate, the outer wall of the push plate is fixedly connected to the moving block, the outer wall of the moving block is socketed with the limiting rod, the outer wall of the limiting rod is wrapped with a first spring, one end of the first spring is fixedly connected to the moving block, the outer wall of the moving block is fixedly connected to two connecting blocks, and the outer walls of the two connecting blocks are equipped with knocking blocks.

[0008] Preferably, the other end of the first spring is fixedly connected to the detection cabinet, and the outer wall of one of the knocking blocks is in contact with the filter screen.

[0009] Preferably, the water absorption plate fixing mechanism includes a second knob, the outer wall of the second knob is adjacent to the detection cabinet, the outer wall of the second knob is threadedly connected to the limit nut, the outer wall of the limit nut is tightly against the detection cabinet, the outer wall of the second knob is fixedly connected to the turntable, the outer wall of the turntable is fixedly connected to the first connecting rod through a pin shaft, the outer wall of the first connecting rod is movably connected to the second connecting rod through a pin shaft, the outer wall of the second connecting rod is slidably connected to the clamping block, and the outer wall of the clamping block is slidably connected to the detection cabinet through a slide groove.

[0010] Preferably, an observation window is installed on the outer wall of the detection cabinet, and two detection sensors are installed inside the detection cabinet.

[0011] Preferably, the outer wall of the wind collecting hood is fixedly connected to the protrusion, the inner wall of the protrusion is slidably connected to the block, the outer wall of the block is fixedly connected to the sliding rod, the outer wall of the sliding rod is fixedly connected to the observation block, the outer wall of the sliding rod is wrapped with a second spring, one end of the second spring is fixedly connected to the protrusion, and the other end of the second spring is fixedly connected to the block.

[0012] The utility model proposes a device for online monitoring and early warning of volatile organic waste gas, and its beneficial effects are: through the cooperation of the detection cabinet and the filter screen knocking mechanism, the first knob drives the cam to rotate, the cam drives the push plate to move, the push plate drives the moving block to move, the moving block drives the first spring to deform and at the same time drives the two connecting blocks to move, the connecting block drives the knocking block to move, the knocking block knocks the filter screen, so that the impurity particles attached to the surface fall on the inner wall of the detection cabinet. The filter screen can be prevented from being blocked in the above manner, which improves the working efficiency of the monitoring and early warning device.

[0013] Through the cooperation of the detection cabinet and the water absorption plate fixing mechanism, the second knob drives the turntable to rotate, and the turntable drives the first connecting rod to rotate. Since the middle part of the first connecting rod rotates on the detection cabinet through the pin shaft, the other end of the first connecting rod will move in the opposite direction, and the first connecting rod drives the second connecting rod to move, and the second connecting rod drives the clamping block to move. The clamping block no longer presses against the water absorption plate, and the water absorption plate falls off from the detection cabinet due to gravity. After that, the operator cleans it, and then inserts the water absorption plate into the detection cabinet. The operator rotates the second knob in the opposite direction and tightens the limit nut to make the clamping block press against the water absorption plate. The above method can avoid the situation where the water absorption plate cannot absorb after absorbing to the limit, which improves the working quality of the monitoring and early warning device.

[0028] Gas monitoring stage:

[0029] First, connect the external power supply of the motor 8 and start the motor 8. The motor 8 drives the exhaust fan 9 to rotate. The exhaust fan 9 sucks the gas into the detection cabinet 1. The gas passes through the filter 3 to filter out most of the solid particles. Then, the moisture in the gas is adsorbed by the water absorption plate 8. The gas is detected by the detection sensor 7. The gas enters the wind hood 10 and pushes the block 15 to drive the slide bar 12 to move. The slide bar 12 drives the second spring 13 to compress and drives the observation block 14 to move. After the block 15 moves to the right, the gas is discharged from the through hole above the protrusion 11. The amount of gas discharged is monitored by observing the position of the observation block 14. The detection sensor 7 can transmit the gas situation to the externally connected computer to warn it, thereby completing the monitoring and early warning of volatile organic waste gas.
