Description

Technical Field

[0001] This utility model relates to the field of odor detection, specifically to a multi-purpose odor detection device for industrial parks. Technical Background

[0002] Industrial parks contain large amounts of odorous gases. These gases pollute the air when released into the atmosphere, and they can also cause direct harm to the human body when inhaled. Therefore, the treatment of odorous gases is urgent, and the prerequisite for treating industrial waste gas is how to quickly and accurately detect odors.

[0003] Patent CN221723970U discloses an industrial multi-purpose odor detection device, including a base. A caster is fixedly mounted on one side of the lower part of the base. A column is fixedly mounted on top of the base. A screw is positioned above the column. A mounting base is positioned above the screw. A housing is fixedly mounted inside the mounting base. A baffle is fixedly mounted on top of the housing. An air inlet shell is fixedly mounted on one side of the housing, and an air outlet shell is fixedly mounted on the other side. A fixing plate is fixedly mounted inside the column. A bearing seat is fixedly mounted below the fixing plate. A threaded sleeve is movably connected below the bearing seat. A gear ring is fixedly mounted on the surface of the threaded sleeve. The device includes a base with casters fixedly mounted on one side of the lower part of the base. A first motor is fixedly installed, and a shaft is fixedly connected below the first motor. A main gear is fixedly installed on the surface of the shaft. A slide rod is fixedly installed on one side of the inside of the column, and a limiting plate is sleeved on the surface of the slide rod. An installation groove is opened on one side surface of the air intake shell. A detection chamber is fixedly installed inside the outer shell, and a sensor group is fixedly installed on the surface of the detection chamber. A pipe is fixedly connected to one side of the detection chamber, and a fixing rod is fixedly installed inside the pipe. A second motor is fixedly installed inside the fixing rod, and a rotating shaft is fixedly connected to one side of the second motor. A turbine blade is fixedly installed on the surface of the rotating shaft, and a brush rod is fixedly installed on one side surface of the rotating shaft. A filter plate is fixedly installed on one side inner wall of the air intake shell.

[0004] However, the above technical solution still has the following technical problems in actual use: The above technical solution uses turbine blades to draw in gas to discharge the gas located in the detection chamber, which causes the gas to be detected to mix with the gas remaining in the detection chamber when it enters the detection chamber, resulting in distorted detection results. In addition, only a filter device for filtering solid impurities is set up, but the gas to be measured is not dehydrated, which will lead to distorted detection results for gases that are easily soluble in water. The practical effect is poor, which reduces the practicality and applicability of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-purpose odor detection device for industrial parks, which can effectively discharge the detected gas from the detection chamber and simultaneously dehydrate the gas to be detected, thereby improving the practicality and applicability of the device.

Detailed Implementation

[0028] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0029] like Figures 1-5The multi-purpose odor detection device for industrial parks shown includes a base 1, with casters 2 connected to the four corners of the base 1. Each caster 2 has a locking pedal. An electric telescopic rod 40 is connected to the top of the base 1, and a movable plate 3 is connected to the movable plate 3. The movable plate 3 is connected to a detection box 4, which includes a housing 5. Support legs 6 are connected to the four corners of the housing 5, symmetrically about the center line of the housing 5. The support legs 6 are connected to the movable plate 3. The housing 5 has a first groove 7, within which a sensor group 8 is connected. A cover 9 is slidably connected to the housing 5, with a second groove 10 at the center of the cover 9, extending through the entire cover 9. A smooth push rod 11 is slidably connected to the inner side of the second groove 10 to reduce friction between the push rod 11 and the second groove 10. A pressure plate 12 is slidably connected to the inner wall of the housing 5, and the pressure plate 12 is connected to the push rod 1. 1. Threaded connection. Both the pressure plate 12 and the push rod 11 are detachable and replaceable. The cover 9 is connected to a ventilation pipe 13, which runs through the entire cover 9. External gas can enter the internal space between the cover 9 and the pressure plate 12 through the ventilation pipe 13. The top wall of the housing 5 is connected to a support column 14, which is connected to a first motor 15. The output end of the first motor 15 is fixedly connected to a crank 16, which is rotatably connected to a connecting rod 17. The connecting rod 17 is rotatably connected to the push rod 11. The bottom of the housing 5 is connected to an exhaust pipe 18, which is equipped with a first one-way valve 19. The first one-way valve 19 is set to allow only gas to be discharged. The side wall of the housing 5 is connected to a gas supply pipe 20, which is equipped with a second one-way valve 21. The second one-way valve 21 is set to allow only gas to be entered. The movable plate 3 is connected to a filter device 22, and the gas supply pipe 20 is connected to the filter device 22.

[0030] The movable plate 3 is connected to a nitrogen tank 23, the nitrogen tank 23 is connected to a nitrogen delivery pipe 24, the nitrogen delivery pipe 24 is equipped with an electric valve 25, the nitrogen delivery pipe 24 is connected to the housing 5, and the nitrogen enters the housing 5 by controlling the electric valve 25.

[0031] The filtration device 22 includes a filter box 26, a vent 27 connected to the filter box 26, a mounting bracket 28 connected to the vent 27, a second motor 29 connected to the mounting bracket 28, a rotating rod 30 connected to the output end of the second motor 29, a brush 31 connected to the rotating rod 30, a filter screen 32 connected inside the vent 27, the filter screen 32 abutting against the brush 31, the size of the brush 31 being larger than the size of the filter screen 32, a water-absorbing layer 33 connected to the inner wall of the filter box 26, and a molecular sieve layer 34 connected to the inner wall of the filter box 26, the molecular sieve layer 34 being located behind the absorption layer 33, the molecular sieve layer 34 being a 3A type molecular sieve.

[0032] The bottom of the cover 9 is connected to a rubber gasket 35 with good airtightness. The push rod 11 is slidably connected to the inner wall of the rubber gasket 35 and passes through the rubber gasket. The ventilation pipe 13 is connected to the inner wall of the rubber gasket 35 and passes through the rubber gasket 35.

[0033] The cover 9 has a third groove 36 on its side wall, and a U-shaped rod 37 is slidably connected to the third groove 36. The upper end of the U-shaped rod 37 extends out of the third groove 36. Several sets of springs 38 are connected to the side wall of the third groove 36. The springs 38 are connected to the U-shaped rod 37. The housing 5 has a limit hole 39 on its side wall, and the lower end of the U-shaped rod 37 is slidably connected to the limit hole 39.

[0034] The following is Figures 1-5 Taking a multi-purpose odor detection device for industrial parks as an example, its working principle is explained as follows: When installing the cover 9, press the upper end of the U-shaped rod 37 to compress the spring 38, causing the spring 38 to move to the right and enter a compressed state. Then, place the cover 9 into the first groove 7 of the housing 5. Then, stop pressing the U-shaped rod 37. At this time, the lower end of the U-shaped rod 37 abuts against the side wall of the housing 5 under the restoring force of the spring 38. When the cover 9 slides in the first groove 7 until the lower part of the cover 9 abuts against the housing 5, the lower end of the U-shaped rod 37 just moves to the right end of the limiting hole 39. At this time, under the restoring force of the spring 38, the lower end of the U-shaped rod 37 inserts into the inner side of the limiting hole 39. Figure 2 As shown, at this point, the cover 9 can no longer move up and down relative to the shell 5. To disassemble, simply reverse the operation.

[0035] Because crank 16 is rotatably connected to connecting rod 17, and connecting rod 17 is rotatably connected to push rod 11, while push rod 11 is slidably connected within the second groove 10, crank 16, connecting rod 17, and push rod 11 form a crank-connecting rod mechanism. When gas is being detected, the first motor 15 is started. Since crank 16 is fixedly connected to the output end of the first motor 15, the crank-connecting rod mechanism reciprocates under the drive of the first motor 15. Because push rod 11 is threadedly connected to pressure plate 12, and pressure plate 12 is slidably connected to the first groove 7, pressure plate 12 can... The pressure plate 12 slides back and forth in the first groove 7. It moves downward until it touches the housing 5, and the gas inside the housing 5 is discharged through the air outlet pipe 18. Then the pressure plate 12 moves upward. At the same time, due to the action of the first one-way valve 19, the outside gas cannot enter the housing 5 through the air outlet pipe 18. The pressure plate 12 draws the gas to be tested from the exhaust pipe 27 into the filter device 22, and enters the housing 5 through the gas supply pipe 20. The sensor group 8 detects the odor of the gas to be tested that enters the housing 5. When other gases need to be detected, the operation can be repeated.

[0036] When the gas to be tested is drawn into the filter device 22, the gas passes through the filter screen 32, leaving solid impurities on the filter screen 32. The second motor 29 is started. Since the rotating rod 30 is fixedly connected to the output end of the second motor 29, and the brush 31 is fixedly connected to the rotating rod 30, the brush 31 will rotate synchronously with the output end of the second motor 29 to clean the solid impurities remaining on the filter screen 32. The gas to be tested entering the filter device 22 passes through the water absorption layer 33 to absorb large molecular water vapor for preliminary dehydration, and then passes through the molecular sieve layer 34. Small molecular water vapor with a molecular diameter greater than 3.0A is removed by sieving, while ensuring that ammonia with a molecular diameter less than 3.0A passes through without being removed, thus completing the filtration of the gas to be tested.

[0037] The specific implementation process is as follows:

[0038] First, install the cover 9, press down on the upper end of the U-shaped rod 37 to compress the spring 38, then place the cover 9 into the housing 5, and then stop pressing down on the U-shaped rod 37. Next, slide the cover 9 downwards until it cannot move. Move the present invention to the desired position using the universal wheels 2 on the lower side of the base 1, and then step on the locking pedal of the universal wheels 2 to fix it. Control the electric telescopic rod 40 to adjust the height of the moving plate 3 to the desired position, open the first one-way valve 19 and the second one-way valve 21, and then start the first motor 15 and the second motor 29 to draw the gas into the filter device 22 and then into the detection chamber 4 to complete the odor detection of the gas. Turn off the first motor 15 and the second motor 29, and then repeat the operation to detect the gas in different heights and different areas. When the detection is completed, open the electric valve 25 to release nitrogen from the nitrogen tank 23 through the nitrogen supply pipe 24 into the detection chamber 4 to discharge the residual gas.
