Description

Technical Field

[0002] Summa canisters are commonly used to collect air samples and are widely used in environmental monitoring, atmospheric pollution research, and other fields. They are primarily used to sample volatile organic pollutants and sulfur compounds in the air, but do not separately sample and test for particulate matter. Once these particles enter the Summa canister, they not only affect the purity of the gas sample and interfere with subsequent analytical results, but can also cause wear and damage to precision components such as sensors and valves within the canister, reducing the canister's service life and reliability.

[0003] In order to improve the filtration efficiency, some existing Suma cans with filtering structures need to frequently replace and clean the filters during use. The entire equipment cannot simultaneously complete the initial self-cleaning operation of the filter during use, resulting in a relatively short overall service life of the filter and the use process is not convenient and efficient. Some filtering structures have fixed filter positions and can adsorb particulate matter during inhalation, but when the gas is discharged, some of the particulate matter is discharged along with the gas sample, affecting the accuracy of subsequent test results of the gas sample.

The fixed plate 17 is provided with a control member for limiting and fixing and adjusting the gas delivery rate in the delivery pipe 6 during the process of driving the rotating disk 5 to rotate.

[0034] The control member includes a first bevel gear 23 which is coaxially connected to the side of the fixed disk 17 for rotation. A first reciprocating screw rod 24 is rotatably connected to the fixed disk 17. The first reciprocating screw rod 24 passes through the push plate 19 and is threadedly connected to the push plate 19.

The first bevel gear 23 is provided with a driving member for adjusting the rotation of the first reciprocating screw rod 24 while driving the sliding tube 9 to perform lifting and lowering adjustments.

[0035] The driving member includes a connecting shaft 28 coaxially fixedly mounted on the first bevel gear 23, a third bevel gear 29 coaxially fixedly connected to the connecting shaft 28, a bevel gear ring 30 meshing with the third bevel gear 29 is rotatably connected in the rotating disk 5, and a sliding member is provided on the rotating disk 5 for driving the sliding tube 9 to slide during the rotation of the bevel gear ring 30, and a control member is provided on the first bevel gear 23 for controlling the operating status of the fixed disk 17 and the second bevel gear 25.

[0036] The operating member includes a driving disk 31 coaxially fixedly mounted on the first bevel gear 23, and a driving ring 32 rotatably connected to the outer wall of the driving disk 31 is fixedly connected to the side of the fixed disk 17. A plurality of groups of spring blocks 33 are provided on the driving disk 31, and a plurality of groups of engaging grooves 34 that can be preliminarily engaged with the tips of the spring blocks 33 are provided on the inner wall of the driving ring 32. A knob 35 is coaxially fixedly connected to the side of the driving disk 31. The purpose of this structure is to increase the friction between the driving disk 31 and the inner wall of the driving ring 32. The depth of the engaging groove 34 is relatively shallow and is only used to increase the friction, and there will be no jamming with the spring blocks 33.

[0037] The sliding member includes multiple groups of sliding blocks 36 fixedly mounted on the outer wall of the sliding tube 9, and multiple groups of second reciprocating screws 37 are rotatably connected in the rotating disk 5. The second reciprocating screws 37 pass through the sliding blocks 36 and are threadedly connected to the sliding blocks 36. The top end of the second reciprocating screw 37 is coaxially fixedly connected with a driving gear 38, and the bevel gear ring 30 is coaxially fixedly connected with an internal gear ring 39 that meshes with multiple groups of driving gears 38. By evenly arranging multiple groups of second reciprocating screws 37, the drive is more stable during the sliding adjustment of the sliding tube 9.

[0038] In this implementation plan, Figure 7 The state shown in FIG is the state that the Suma tank slowly collects the external gas. At this time, the clamping block 18 rotates to the triangular groove 22 at the upper end of the upper arc groove 21 for clamping. Thereafter, it continues to move along the attached Figure 1The knob 35 is rotated counterclockwise in the middle. Due to the restriction of the arc groove 21, the spring block 33 cannot continue to drive the clamping groove 34 and the drive ring 32 to rotate synchronously. At this time, the knob 35 only drives the first bevel gear 23 to rotate, and the first bevel gear 23 synchronously drives the second bevel gear 25 and the third bevel gear 29 to rotate. The second bevel gear 25 drives the first reciprocating screw 24 to make the push plate 19 slide, and the push plate 19 gradually moves toward the side of the clamping block 18 to compress the return spring 20, so that the clamping block 18 gradually increases the clamping force on the triangular groove 22. At the same time, the third bevel gear 29 drives the bevel gear ring 30 to rotate, and synchronously drives the multiple groups of drive gears 38 to rotate through the inner gear ring 39, so that the second reciprocating screw 37 drives the sliding block 36 and the sliding tube 9 Sliding in the delivery pipe 6, the sliding pipe 9 gradually slides up, so that the second strip groove 27 is gradually connected with the first strip groove 26, and as the second strip groove 27 moves upward, the connection relationship with the first strip groove 26 is gradually increased, so that the opening and closing state of the delivery pipe 6 can be adjusted, and the size of the gas delivery amount in the pipeline can be controlled at the same time (the larger the communication opening, the faster the gas delivery). After adjusting to the set communication opening size, the operation can be stopped. At this time, the clamping block 18 and the triangular groove 22 are tightly clamped and limited. Through the vacuum state in the tank body 1, the external gas is pumped into the tank body 1 through the exhaust pipe 10, the fixed pipe 8, the delivery pipe 6 and the connecting pipe 11. At the same time, the gas is filtered by the filter screen 7 in the fixed pipe 8, and the particulate matter is blocked in the upper area.

[0039] It is worth noting that some existing filtering devices will block particulate matter at a position near one end of the exhaust pipe 10 through the filter 7 when exhausting the sampled gas in the tank body 1. Then, when the sampled gas in the tank body 1 is discharged, the position of the filter 7 remains unchanged, and the gas inside the tank body 1 is discharged from the exhaust pipe 10 in the reverse direction, which will cause some of the particulate matter originally blocked on the upper side to be carried away by the reversely discharged gas, so that the gas detection process will still contain some particulate impurities, affecting the detection efficiency. When the present solution is used to detect the discharge of the gas in the tank body 1, it is necessary to rotate the knob 35 clockwise to make the first bevel gear 23 rotate in the reverse direction, driving the first reciprocating screw 24 and the second reciprocating screw 37 to rotate in the reverse direction synchronously, gradually lowering the engagement of the clamping block 18 with the triangular groove 22, and at the same time, the sliding tube 9 slides in the reverse direction to release the first strip groove 26 and the second strip groove 27. When the clamping force of the clamping block 18 on the triangular groove 22 is less than the driving force of the spring clamping block 33 on the clamping groove 34, the driving disk 31 and the driving ring 32 can be synchronously driven to rotate in the opposite direction during the rotation of the knob 35. When one end of the fixed tube 8 is rotated to be connected with the first pipe 12, the side hole 15 is connected with the air inlet 16 at this time. Since the first pipe 12 and the storage tank 4 are in a vacuum state, and the first strip groove 26 and the second strip groove 27 are not connected, the outside air can be drawn into the fixed tube 8 through the air inlet 16 and the side hole 15, and then transported back to the first pipe 12 through the filter screen 7, so that the particulate impurities adsorbed on the filter screen 7 are blown out in the opposite direction to the storage tank 4 for collection, thereby realizing the function of auxiliary self-cleaning, extending the service life of the filter screen 7, and improving the continuous adsorption efficiency of the filter screen 7.

[0040] When the filter 7 is in the closed position, the filter 7 is in the closed position, and the filter 7 is in the closed position, so that the filter 7 is in the closed position.

[0041] It should be noted that the first reciprocating screw 24 and the second reciprocating screw 37 in the device have the same direction conversion position for the push plate 19 and the sliding block 36, that is, when the push plate 19 reaches one end of the first reciprocating screw 24 and slides in the opposite direction, the sliding block 36 also reaches one end of the second reciprocating screw 37 and switches to sliding in the opposite direction, thereby ensuring that the moving state of the clamping block 18 is the same as the sliding state of the sliding tube 9. When the clamping block 18 is subjected to an increased thrust by the return spring 20, the through hole connecting the second strip groove 27 on the sliding tube 9 and the corresponding first strip groove 26 gradually increases.

[0042] By setting the control of the clamping block 18 and the sliding tube 9, when it is necessary to switch the rotating disk 5 to reverse rotation, the reverse rotation knob 35 will not directly drive the rotating disk 5 to rotate in the reverse direction. Instead, the clamping block 18 is first controlled to gradually release the clamping, and the sliding tube 9 is controlled to reset at the same time, so that the first strip groove 26 and the second strip groove 27 are no longer connected. Only then can the rotating disk 5 be controlled to rotate and switch, thereby avoiding the situation where the upper and lower ends of the delivery pipe 6 are still connected during and after the switching process, and the external gas continues to be reversely drawn into the interior of the tank body 1, affecting the sealing of the tank body 1 and the gas collection state.

[0043] When the gas output test after sampling is completed, rotate the knob 35 until the first strip groove 26 and the second strip groove 27 are disconnected, open the control valves on the second pipe 13 and the third pipe 14, and connect them with the third pipe 14 through the vacuum pump to perform vacuuming. The gas and impurities in the storage tank 4 and the tank body 1 can be simultaneously extracted, and the control valves of the second pipe 13 and the third pipe 14 can be closed after the vacuuming is completed. Thereafter, the filter 7 can be rotated to the upper side for gas collection as needed, or the filter 7 can be rotated to the side facing the first pipe 12 for self-cleaning, or the filter 7 can be rotated downward for exhaust operation after sampling. The overall structure of the equipment has strong integrity, and can automatically control the inlet and outlet gas status, the position of the filter 7 and the self-cleaning status of the filter 7 during the switching process, and the operation is convenient and efficient.
