Description

Technical Field

[0001] This invention relates to the technical field of absorption tube drying devices, specifically to an environmental monitoring gaseous pollutant absorption tube drying device. Background Technology

[0002] Monitoring of air and exhaust pollutants (including gaseous pollutants, aerosols, etc.) requires on-site sampling followed by laboratory analysis to obtain monitoring and analysis results. Whether the analysis results can accurately reflect the true level of air quality and the true degree of air pollution is closely related to the collection efficiency of gaseous pollutants during on-site sampling.

[0003] The absorption tube method is used for monitoring the gaseous environment. This method is used to determine the number of airborne bacteria. A fixed amount of air is passed through an absorption tube containing an absorption solution, which is then incubated on a nutrient agar plate. The number of colonies is counted, and the total number of bacteria per cubic meter of air is calculated based on the volume of the air sample.

[0004] After use, the absorption tube needs to be cleaned. However, the cleaned absorption tube is not easy to dry, and an undried absorption tube will affect the monitoring accuracy. At this time, it is necessary to use an absorption tube drying device to quickly dry the absorption tube. Existing absorption tube drying devices place the absorption tube in a drying box and heat it by passing hot air through it. During the drying process, the outer wall of the absorption tube is heated first, and then the temperature is transferred to the inner wall to dry it. This drying method is slow, resulting in low drying efficiency of the absorption tube and affecting the quick use of the absorption tube after cleaning. Summary of the Invention

[0005] The purpose of this invention is to provide an environmental monitoring gaseous pollutant absorption tube drying device that can improve drying efficiency, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drying device for an absorption tube of gaseous pollutants for environmental monitoring, comprising a housing, a lifting box, and an air-pressing assembly. The top of the housing is provided with a placement platform, and a water receiving trough is provided above the placement platform. A pressing assembly is provided on one side of the placement platform. The lifting box is installed inside the housing and connected to the interior of the housing on both sides via the lifting assembly. A drying assembly is provided inside the lifting box, one end of which penetrates the water receiving trough and extends outward to dry the absorption tube placed upside down on the placement platform. The air-pressing assembly is installed inside the lifting box to press the hot air inside the lifting box. The compressed air is pushed into the inverted absorption tube on the placement platform, accelerating the flow of hot air inside the lifting box. By adding a drying component, the absorption tube at the water tank on the inverted placement platform can be dried. In conjunction with the lifting component, air pushing component, and transmission rotation component, the air flow in the lifting box can be accelerated and discharged through the air outlet to dry the inner wall of the absorption tube. At the same time, the air outlet can be driven to lift and rotate, achieving drying of the inner wall of the absorption tube at different heights and directions. This can effectively improve the drying efficiency of the absorption tube, directly contact the inner wall of the absorption tube, reduce heat transfer time, shorten the drying time of the absorption tube, and improve the working efficiency of the absorption tube drying.

A base is fixedly disposed at the bottom of the box, and the motor is disposed on the base. By adding the lifting assembly, the lifting box can be driven to rise and fall inside the box, which can drive the air outlet pipe in the drying assembly to rise and fall in the water receiving tank and extend into the interior of the absorption pipe.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1-8The diagram shows a drying device for an environmental monitoring gaseous pollutant absorption tube, comprising a housing 1, a lifting box 4, and an air pushing assembly. The housing 1 has a placement platform 2 on its top, with a water receiving trough 3 above the platform 2. A pressing assembly is located on one side of the platform 2. The lifting box 4 is installed inside the housing 1, and its two sides are connected to the interior of the housing 1 via the lifting assembly. A drying assembly is located inside the lifting box 4, with one end extending outward through the water receiving trough 3 to dry the absorption tube placed upside down on the placement platform 2. The air pushing assembly is installed inside the lifting box 4, compressing and pushing the hot air inside the lifting box into the upside-down absorption tube on the placement platform 2, thus accelerating the flow of hot air inside the lifting box 4.

[0033] When using the absorption tube for drying gaseous pollutants in environmental monitoring: First, invert the absorption tube to be dried on the placement platform 2, and align the tube opening with the water collection tank 3. At this time, the water in the washed absorption tube can flow into the water collection tank 3, and the water collection tank 3 will collect the water.

[0034] Then, the drying component inside the lifting box 4 is activated. The drying component extends through the placement platform 2 into the water receiving tank 3, enabling the drying component to extend upward from the water receiving tank 3 to dry the inverted absorption tube. Hot air is sprayed into the inside of the absorption tube to dry the inner wall of the absorption tube.

[0035] When the drying assembly is used to dry the inside of the absorption tube, the air compression assembly can push the air inside the lifting box 4, accelerate the discharge of the heated air in the lifting box 4, and increase the air flow into the inner wall of the absorption tube for drying, which can effectively improve the drying effect of the absorption tube.

[0036] Example 2

[0037] Please see Figures 1-8 This embodiment further explains Example 1. The box 1, lifting box 4, and air pushing assembly shown in the figure are as follows: The top of the box 1 is provided with a placement platform 2, and a water receiving trough 3 is opened above the placement platform 2. A pressing assembly is provided on one side of the placement platform 2; The lifting box 4 is installed inside the box 1, and its two sides are connected to the inside of the box 1 through the lifting assembly. The lifting box 4 is provided with a drying assembly. One end of the drying assembly passes through the water receiving trough 3 and extends outward to dry the absorption tube placed upside down on the placement platform 2; The air pushing assembly is installed inside the lifting box 4, and compresses the hot air inside the lifting box and pushes it into the upside down absorption tube on the placement platform 2, thereby accelerating the flow of hot air inside the lifting box 4.

[0038] Please see Figures 2-5 The drying assembly shown in the figure includes a heating tube 5 located inside the lifting box 4, and the two sides of the heating tube 5 are connected to the inside of the lifting box 4 through a mounting bracket 6.

[0039] Please see Figures 2-5 The drying assembly shown in the figure also includes multiple air outlet pipes 7 connected to the top of the lifting box 4.

One end of the air outlet pipe 7 is rotatably connected to the top of the lifting box 4 through the bearing sleeve 9, and the other end of the air outlet pipe 7 passes through the placement platform 2 and extends into the interior of the water receiving tank 3. The air outlet pipe 7 is connected to the transmission rotation assembly.

[0040] Please see Figures 2-7 The air thrust assembly shown in the figure includes piston push plates 10 located on both sides inside the lifting box 4. A first toothed plate 11 is fixedly provided on one side of the piston push plate 10. The first toothed plate 11 is meshed with one side of the first gear 12. A guide rod 40 is fixedly provided on one side of the first toothed plate 11. The guide rod 40 is slidably provided inside the guide hole 41. The guide hole 41 is opened on the mounting bracket 6. The first gear 12 is fixedly sleeved on the rotating cylinder 13. Both ends of the rotating cylinder 13 pass through the lifting box 4 and extend outward. The rotating cylinder 13 is rotatably connected to the lifting box 4. A cross groove 14 is opened on the inner wall of the rotating cylinder 13. A rotating rod 15 is inserted inside the rotating cylinder 13. Limiting strips 16 matching the cross groove 14 are fixedly provided at equal intervals on the outer wall of the rotating rod 15. One end of the rotating rod 15 passes through the box 1 and extends outward to be fixedly connected to the second gear 17.

[0041] Please see Figures 2-7 The air thrust assembly shown in the figure also includes a turntable 18. One side of the turntable 18 is connected to the lifting assembly. A push column 19 is fixedly provided at the eccentric part of one side of the turntable 18. The push column 19 is slidably disposed inside the groove rod 20. A second toothed plate 21 is fixedly provided on one side of the groove rod 20. The second toothed plate 21 is meshed with the second gear 17. A slide plate 42 is fixedly provided on one side of the second toothed plate 21. The slide plate 42 is slidably connected to the slide rail. The slide rail is fixedly installed at the bottom of the housing 1.

[0042] Please see Figures 3-5 The lifting assembly shown in the figure includes nuts 22 fixedly installed on both sides of the lifting box 4. Both sides of the lifting box 4 are provided with reciprocating screws 23. The nuts 22 are threaded onto the reciprocating screws 23 respectively. One end of the reciprocating screws 23 is rotatably connected to the inside of the housing 1, and the other ends of the two reciprocating screws 23 pass through the housing 1 and extend outward to be fixedly connected to the third gear 44. The two third gears 44 are connected by a toothed chain 45. One end of one reciprocating screw 23 passes through the housing 1 and extends outward to be fixedly connected to one side of the turntable 18. One end of the other reciprocating screw 23 passes through the housing 1 and extends outward to be connected to the output end of the motor 24. A base 43 is fixedly installed at the bottom of the housing 1, and the motor 24 is installed on the base 43.

[0043] Please see Figure 3 and Figure 5The transmission rotation assembly shown in the figure includes a first pulley 25 located on one side above the lifting box 4, and the first pulley 25 is fixedly sleeved on the rotating drum 13; the transmission rotation assembly also includes a second pulley 26 fixedly located on the air outlet pipe 7, and the first pulley 25 and the second pulley 26 are connected by a belt 27.

[0044] In this embodiment, when drying the absorption tube, the absorption tube to be dried is first inverted on the placement platform 2 and the tube opening is aligned with the water receiving tank 3. Then, the motor 24 in the lifting assembly is started. The motor 24 drives the reciprocating screw 23 at the output end to rotate. A third gear 44 is fixed on the reciprocating screw 23, and the third gear 44 is meshed with the third gear 44 on another reciprocating screw 23 through a toothed chain 45. This allows the reciprocating screw 23 to rotate, and the third gear 44 and toothed chain 45 can drive the other reciprocating screw 23 to rotate, so that the two reciprocating screws 23 on both sides of the lifting box 4 can rotate simultaneously. The rotation of the reciprocating screw 23 can drive the nut 22 threadedly connected above it to move. One side of the nut 22 is fixedly connected to the lifting box 4, so that the rotation of the reciprocating screw 23 can drive the nut 22 to move up and down. The up and down movement of the nut 22 drives the lifting box 4 to move up and down inside the box 1, thus realizing the lifting movement of the lifting box 4.

[0045] When the motor 24 is started, the heating tube 5 inside the lifting box 4 is energized. The energized heating tube 5 heats the air inside the lifting box 4, and the heated air enters the air outlet pipe 7 at the top of the lifting box 4. The air outlet pipe 7 has an air outlet hole 8 that overflows. Since the air outlet pipe 7 passes through the placement platform 2 and extends into the water tank 3, it can dry the inverted absorption tube on the water tank 3. The lifting box 4 moves up and down under the drive of the lifting assembly, and it can also drive the air outlet pipe 7 to move up and down in the water tank 3. The up and down movement of the air outlet pipe 7 can blow hot air to dry the inner wall of the absorption tube at different heights, which can accelerate the drying of the inner wall of the absorption tube and improve the drying efficiency of the inner wall of the absorption tube.

[0046] The motor 24 starts and drives the reciprocating screw 23 to rotate. One end of the reciprocating screw 23 is fixedly equipped with a turntable 18. When the reciprocating screw 23 rotates, it drives the turntable 18 to rotate. The rotation of the turntable 18 drives the push column 19 at one side to move. At this time, the push column 19 can push the grooved rod 20. The grooved rod 20, pulled by the push column 19, can drive the second gear 17 to reciprocate. Since a slide plate 42 is fixedly provided on one side of the second gear 17 and the slide plate 42 is slidably disposed inside the slide rail, it can support and guide the second gear plate 21, increasing the safety of the reciprocating movement of the second gear plate 21. Since one side of the second gear plate 21 is meshed with the second gear 17, it can mesh with the belt while the second gear plate 21 is reciprocating. The second gear 17 reciprocates. Since the second gear 17 is fixedly installed on the rotating rod 15, and one end of the rotating rod 15 passes through the housing 1 and extends into it to be fixedly connected to the limiting strip 16, the rotating rod 15 is inserted into the inside of the rotating cylinder 13, and the limiting strip 16 is inserted into the cross slot 14, which can realize the limiting between the rotating rod 15 and the rotating cylinder 13 and realize the lifting and sliding of the rotating cylinder 13 on the rotating rod 15. When the rotating rod 15 rotates, it can drive the rotating cylinder 13 to rotate. The rotation of the rotating cylinder 13 can drive the first gear 12, which is fixedly sleeved on the outside of the rotating cylinder 13, to rotate. Since the first gear 12 is meshed on both sides, the rotation of the first gear 12 can push and pull the first toothed plate 11 to move. The movement of the first toothed plate 11 can push and pull the piston push plate 10.

[0047] Because the rotating rod 15 rotates back and forth under the drive of the second gear 17 and the second toothed plate 21, it can drive the rotating drum 13 to rotate back and forth. The rotation of the rotating drum 13 can drive the first gear 12 to rotate back and forth. The first gear 12 drives the first toothed plate 11 to push and pull back and forth inside the lifting box 4, which can realize the opposite and opposite movements of the two piston push plates 10. When the two piston push plates 10 move towards each other, they can push and squeeze the air inside the lifting box 4. After the air inside the lifting box 4 is squeezed, it is discharged through the air outlet pipe 7 connected to the top of the lifting box 4. This speeds up the discharge of the hot air heated by the heating pipe 5 inside the lifting box 4 to dry the absorption pipe inverted at the water receiving tank 3. It can speed up the flow of hot air and improve the drying efficiency of the absorption pipe.

[0048] While the rotating rod 15 drives the rotating drum 13 to rotate, the transmission rotation assembly will also rotate. The rotating rod 15 drives the rotating drum 13 to rotate, and the rotation of the rotating drum 13 can drive the first pulley 25, which is fixedly connected at one end, to rotate. The first pulley 25 and the second pulley 26 are connected by a belt 27. When the first pulley 25 rotates, it can drive the second pulley 26 to rotate through the belt 27. The second pulley 26 is fixedly installed on the air outlet pipe 7. The rotation of the second pulley 26 can drive the rotation of the air outlet pipe 7. One end of the air outlet pipe 7 is connected to the top of the lifting box 4 through a bearing sleeve 9, so that the air outlet pipe 7 can rotate on the top of the lifting box 4. With the lifting assembly driving the movement of the lifting box 4, the air outlet pipe 7 can rotate while being lifted, thus realizing the rotation of the air outlet pipe 7. When inserted into the inverted absorption tube, the device rotates and rises, causing hot air from the outlet pipe 7 to overflow from the outlet hole 8 and contact the inner wall of the absorption tube at different heights and directions. This increases the contact area between the hot air and the inner wall of the absorption tube, effectively improving the heating and drying efficiency of the absorption tube. This avoids the traditional method of placing the absorption tube in a heating cabinet, where hot air first dries and heats the outer wall of the absorption tube before transferring heat to the inner wall. This simple placement structure effectively drains water stains from the inner wall of the absorption tube, accelerating the drying effect of hot air on the inner wall. Simultaneously, the direct contact between the hot air and the inner wall of the absorption tube shortens the heat transfer time, effectively improving the drying efficiency inside the absorption tube and facilitating operation for staff.

[0049] Example 3

[0050] Please see Figures 1-8 This embodiment further illustrates other embodiments. The box 1, lifting box 4, and air pushing assembly shown in the figure are as follows: The top of the box 1 is provided with a placement platform 2, and a water receiving trough 3 is provided above the placement platform 2. A pressing assembly is provided on one side of the placement platform 2. The lifting box 4 is installed inside the box 1, and its two sides are connected to the inside of the box 1 through the lifting assembly. The lifting box 4 is provided with a drying assembly. One end of the drying assembly passes through the water receiving trough 3 and extends outward to dry the absorption tube placed upside down on the placement platform 2. The air pushing assembly is installed inside the lifting box 4 and compresses the hot air inside the lifting box and pushes it into the upside-down absorption tube on the placement platform 2, thereby accelerating the flow of hot air inside the lifting box 4.

[0051] Please see Figure 2 and Figure 7 The two ends of the rotating drum 13 and the lifting box 4 in the figure are connected by the first rotating sealing ring 28, and the two ends of the air outlet pipe 7 and the water receiving tank 3 are connected by the second rotating sealing ring 29.

[0052] Please see Figure 2The air outlet pipe 7 shown in the figure is fitted with a deflector pipe 30 on the outside. One end of the deflector pipe 30 is fixedly connected to the inner wall of the water receiving tank 3, and the deflector pipe 30 is fitted on the outside of the second rotating sealing ring 29.

[0053] Please see Figure 1 and 2 In the figure, each pair of adjacent water tanks 3 are connected by a connecting hole 31, and a drain pipe 32 is provided on one side of the box body 1. One side of the drain pipe 32 is connected to the water tank 3 through a branch pipe. A control valve is provided on the drain pipe 32.

[0054] Please see Figure 8 The water receiving tank 3 shown in the figure has a groove 33 at one end and on the placement platform 2. Drip holes 34 connected to the water receiving tank 3 are provided at equal intervals on the side wall of the groove 33.

[0055] In this embodiment, the connection between the rotating drum 13 and the lifting box 4 is made by a first rotating sealing ring 28, which improves the sealing of the connection between the rotating drum 13 and the lifting box 4. This prevents the hot air from overflowing from the connection between the rotating drum 13 and the lifting box 4 when the piston push plate 10 moves in opposite directions. It also effectively improves the discharge of hot air through the air outlet pipe 7. The connection between the air outlet pipe 7 and the placement platform 2, and the connection extending into the water tank 3, is made by a second rotating sealing ring 29, which prevents water in the water tank 3 from flowing into the interior of the box 1. At the same time, during installation, a flow-proof pipe 30 is provided on the outside of the second rotating sealing ring 29. The flow-proof pipe 30 can block the water collected in the water tank 3. The flow-proof pipe 30 is sleeved on the air outlet pipe 7, which can prevent water collected in the water tank 3 from entering the air outlet pipe 7 through the air outlet hole 8 on the air outlet pipe 7 and flowing into the inner wall of the lifting box 4, thus affecting the heating tube 5. This effectively improves the safety of the heating tube 5.

[0056] Two adjacent water tanks 3 are connected by a connecting hole 31, and a drain pipe 32 is provided on one side of the box body 1. The drain pipe 32 is connected to the water tank 3 on the side by a branch pipe, so that the water collected in the water tank 3 can be discharged into the drain pipe 32 through the connecting hole 31 and the branch pipe, and discharged by the drain pipe 32. This prevents the water level inside the water tank 3 from being too high and causing the collected water to overflow the anti-flow pipe 30 and enter the air outlet pipe 7, thus increasing the safety of the heating pipe 5 in the lifting box 4.

[0057] A groove 33 is provided at the opening of the water receiving tank 3, which makes it convenient for the end of the absorption tube to be inverted and placed into the groove 33. A drip hole 34 communicating with the water receiving tank 3 is provided at the edge of the groove 33, so that when the absorption tube is inverted at the end of the groove 33 after cleaning, the water inside the absorption tube can slide down the tube wall and drip into the water receiving tank 3 through the drip hole 34. This realizes the drainage of water sliding down the inner wall of the absorption tube into the water receiving tank 3, which can reduce water stains on the inner wall of the absorption tube and facilitate the drying of the inner wall of the absorption tube by hot air.

[0058] Example 4

[0059] Please see Figures 1-8 This embodiment further illustrates other embodiments. The box 1, lifting box 4, and air pushing assembly shown in the figure are as follows: The top of the box 1 is provided with a placement platform 2, and a water receiving trough 3 is provided above the placement platform 2. A pressing assembly is provided on one side of the placement platform 2. The lifting box 4 is installed inside the box 1, and its two sides are connected to the inside of the box 1 through the lifting assembly. The lifting box 4 is provided with a drying assembly. One end of the drying assembly passes through the water receiving trough 3 and extends outward to dry the absorption tube placed upside down on the placement platform 2. The air pushing assembly is installed inside the lifting box 4 and compresses the hot air inside the lifting box and pushes it into the upside-down absorption tube on the placement platform 2, thereby accelerating the flow of hot air inside the lifting box 4.

[0060] Please see Figure 1 and Figure 8 The pressing assembly shown in the figure includes a pressing plate 35, one end of which is fixedly connected to a shaft 36. The shaft 36 is connected to one side of the placement platform 2 via a first bearing bracket, and a worm gear 37 is fixedly provided at one end of the shaft 36. A worm 38 is meshed on one side of the worm gear 37, and a crank handle 39 is fixedly provided at one end of the worm 38. Both ends of the worm 38 are connected to the housing 1 via a second bearing bracket.

[0061] In this embodiment, a pressing component is provided on one side of the placement platform 2, which can press down on the inverted absorption tube, preventing hot air from pushing and damaging the inverted absorption tube when pushed by the air pushing component, thus increasing the safety of drying the absorption tube in an inverted position. In actual use, after the absorption tube is inverted on the placement platform 2, the operator turns the crank handle 39. The rotation of the crank handle 39 can drive the worm gear 38 to rotate. The worm gear 38 meshes with the worm wheel 37. At this time, the worm gear 38 can drive the worm wheel 37 to rotate. The worm wheel 37 is fixedly sleeved on one end of the shaft 36. When the worm wheel 37 rotates, it can drive the shaft 36 to rotate. The rotation of the shaft 36 can drive the pressing plate 35 fixedly installed on the shaft 36 to rotate. At this time, the pressing plate 35 rotates around the shaft 36 as the center, so that the pressing plate 35 rotates on one side of the placement platform 2, thereby pressing and clamping the edge of the inverted absorption tube on the placement platform 2, increasing the safety of drying the absorption tube in an inverted position.
