Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a device for capturing water-soluble components in the atmosphere and capture and extraction equipment. Background Art

[0002] The detection of water-soluble components in the atmosphere is widely used in various fields of production, especially in the field of environmental monitoring. Many particulate matter in the atmosphere is water-soluble, so the monitoring of water-soluble components in the atmosphere can reflect the atmospheric air quality to a certain extent.

[0003] In existing technology, metal fiber sintered felt filters, characterized by high porosity and recyclability, are typically used to concentrate water-soluble components in the atmosphere, thereby capturing soluble components. However, in practice, as the captured atmosphere flows through the membrane, the membrane's flatness significantly impacts the uniformity of the soluble components' accumulation, which in turn affects the adequacy of subsequent elution and can even affect the final monitoring results. Furthermore, after a set operating time, the membrane typically requires thorough cleaning before use, impacting detection continuity. Utility Model Content

[0004] The utility model discloses a device and equipment for capturing and extracting water-soluble components in the atmosphere. It solves the technical problems of poor uniformity in the enrichment of soluble components on the filter membrane and inconvenient assembly and disassembly of the filter membrane in the prior art. It has a reasonable structure, is easy to use, and is conducive to improving the uniformity of enrichment of soluble substances on the filter membrane. The technical solution adopted is as follows:

[0005] A device for capturing water-soluble components in the atmosphere, comprising an enrichment assembly, a rotating disk, and a second drive unit. The rotating disk comprises a plurality of radially extending and circumferentially arranged support plates, the ends of which are clamped by clamping assemblies to hold filter membranes. When the second drive unit drives the filter membrane to rotate toward the enrichment assembly, the enrichment assembly can enrich soluble components in the atmosphere flowing through the filter membrane.

[0006] The clamping assembly includes a lower cover and an upper cover. The lower cover is laterally fixed to the support plate. The upper cover is sleeved in the lower cover to press the filter membrane onto the annular flange on the inner wall of the lower cover.

[0007] On the basis of the above technical solution, the outer wall surface of the upper cover is provided with an external thread, and the inner wall surface of the lower cover is provided with an internal thread matching the external thread.

[0008] On the basis of the above technical solution, a plurality of ribs are fixedly provided in the upper cover, and the center of mass of the integral component formed by the plurality of ribs is on the central axis of the upper cover.

[0009] On the basis of the above technical solution, the filter membrane is a stainless steel metal fiber sintered felt, and the filtration pore size of the filter membrane is not greater than 2.5 μm.

[0010] Based on the above technical solution, the enrichment component includes an atmospheric cutter, an upper pressing cover, a lower pressing cover and a third driving unit. The upper pressing cover is connected to the atmospheric cutter through a hose, and the lower pressing cover is connected to the outside world through an exhaust pipe. The third driving unit can drive the upper pressing cover and the lower pressing cover to move closer or farther away. When the upper pressing cover and the lower pressing cover are close, the upper pressing cover and the lower pressing cover can clamp the filter membrane up and down and form a closed chamber, so that the water-soluble components in the gas entering the closed chamber through the gas cutter are enriched on the filter membrane.

[0011] On the basis of the above technical solution, when the upper pressing cover and the lower pressing cover can clamp the filter membrane up and down to form a closed chamber, the filter membrane is arranged between the upper pressing cover and the upper cover.

[0012] A device for capturing and extracting water-soluble components in the atmosphere comprises a movable seat, an elution assembly, a first drive unit and the above-mentioned capture device, wherein the capture device is fixed on the movable seat and can be displaced up and down under the action of the first drive unit, the elution assembly comprises a first cell body, a second cell body and an ultrasonic generator, the first cell body is sleeved outside the second cell body, and the ultrasonic wave emitted by the ultrasonic generator can be transmitted to the eluent in the second cell body through the liquid in the first cell body; when the turntable rotates to rotate the filter membrane at a higher position to the enrichment assembly, the filter membrane at a lower position rotates to above the second cell body; the hose is designed to have toughness, and when the movable seat is displaced to the lower limit position under the action of the first drive unit and the filter membrane is immersed in the eluent in the second cell body, the hose is straightened.

[0013] Based on the above technical solution, the inner wall surface of the second cell body is adapted to the outer edge of the clamping assembly so that a small amount of eluent maintains a higher liquid level depth, and the liquid level height in the first cell body is not lower than the liquid level height in the second cell body.

[0014] On the basis of the above technical solution, it also includes a box body that is covered outside the capture and extraction device, and an opening is provided on the side wall of the box body facing the turntable, and a door panel is hinged at the opening. A vertical panel is provided in the box body, and a notch is provided on the vertical panel for the movable seat to pass through. The vertical panel, door panel and box body together enclose an independent chamber for accommodating the enrichment component, turntable and elution component, so as to be relatively separated from other components.

[0015] On the basis of the above technical solution, the outer cover of the box body is provided with a shell, and one or more of an air conditioner, a sterilizer, and a temperature sensor are provided in the shell, and an extraction liquid collecting device is also accommodated in the shell.

[0016] Beneficial effects

[0017] The utility model has a reasonable structure. The clamping assembly includes an upper cover and a lower cover. The upper cover and the lower cover cooperate to better fix the flattened filter membrane, stably clamp the filter membrane, and at the same time improve the uniformity of the enrichment of soluble substances on the filter membrane, thereby facilitating sufficient elution. At the same time, the upper cover and the lower cover are easy to screw together and operate. The setting of the rib plate, on the one hand, better supports the filter membrane to maintain a flat state, and on the other hand, facilitates the screwing of the upper cover and the disassembly and assembly of the filter membrane. In addition, during the enrichment process, the filter membrane is arranged close to the upper pressing cover, and during the elution process, the filter membrane is arranged close to the inner bottom surface of the second tank body. This is conducive to the enrichment of soluble substances on the filter membrane while ensuring sufficient elution. The structural design is reasonable.

[0018] In this application, the enrichment component can allow the gas flowing through the gas cutter to pass through the filter membrane, so that the water-soluble components in the gas are enriched on the filter membrane. The hose connecting the gas cutter and the upper pressing cover is designed so that when the gas enters the closed chamber inside the upper and lower pressing covers, the hose is in a straightened state. This can greatly reduce the residual soluble components in the gas in the hose, which is conducive to further improving the detection accuracy.

[0019] The elution component in the present application includes a first pool body and a second pool body that are arranged in a sleeve, and the design is ingenious. On the one hand, the first pool body is flexibly configured, and products in the existing technology can be selected to avoid non-standard customization, which is conducive to reducing costs and has good flexibility of use. On the other hand, the second pool body is designed to be compatible with the outer edge of the clamping component that clamps the filter membrane. In this way, in a single elution process, a small amount of eluent can be used to ensure a sufficient liquid level depth, so that the filter membrane can be better immersed in the eluent, which is conducive to improving the elution effect. Compared with the prior art of directly eluting in the first pool body and obtaining a larger volume and lower concentration of extract, the single elution in the present application consumes less eluent, and the concentration of water-soluble components in the obtained extract is high, which is conducive to improving the subsequent detection accuracy. On the other hand, the same filter membrane in the present application can not only extract soluble components to a large extent after multiple elutions, but also complete the filter membrane cleaning operation at the same time, avoiding the generation of waste liquid and further improving the detection accuracy. In addition, the small amount of eluent used is also conducive to reducing costs, while also reducing the cost of waste liquid treatment, greatly reducing the cost of use.

[0020] In the present application, the enrichment component, elution component and turntable are placed in a chamber of the box body, separating the elution component and the enrichment component from other components of the capture and extraction device. A shell is provided on the outer cover of the box body to further isolate the chamber from the atmosphere, thereby preventing the filter membrane from being contaminated or affected while waiting for elution or enrichment, which is beneficial to improving the stability of the detection results.

[0034] like Figures 1-3The device shown in the figure for capturing water-soluble components in the atmosphere comprises an enrichment component 5 , a rotating disk 6 and a second driving unit 7 .

[0035] like Figure 1 As shown, the turntable 6 includes several support plates extending radially and arranged circumferentially, the ends of the support plates clamp the filter membrane 8 through the clamping assembly 9, and the second driving unit 7 includes a second stepper motor, which is fixed and can transmit the rotational motion to the turntable 6 through the rotor.

[0036] It also includes a first baffle, a first optical coupler, a first position sensor and a second position sensor. The first baffle is fixed on the rotor and rotates synchronously with the turntable 6. The first optical coupler is fixedly set to identify the first baffle and can send a signal to the external controller to reset the turntable 6 to its initial position after work.

[0037] The first position sensor and the second position sensor are fixedly arranged and designed so that when the turntable 6 is working normally, the first position sensor and the second position sensor can be separately arranged on both sides of the support plate in the width direction and close to both sides of the support plate; when there is an error in the rotation angle of the turntable 6, the first position sensor or the second position sensor identifies the support plate and sends a signal to the external controller, thereby sending a prompt message to the staff.

[0038] In this embodiment, filter membrane 8 is a stainless steel fiber sintered felt with a 2 μm pore size. It can intercept water-soluble gas components with a particle size larger than the pore size and can be recycled after cleaning. Filter membrane 8 is prior art and will not be described in detail here. In other embodiments of the present invention, filter membrane 8 can be made of other metal fiber sintered felt materials with a pore size of less than 2.5 μm.

[0039] like Figure 2 As shown, the clamping assembly 9 includes a lower cover 902 and an upper cover 901. The lower cover 902 is fixed to the support plate laterally, and the upper cover 901 is sleeved in the lower cover 902. The outer wall of the upper cover 901 is provided with an external thread, and the inner wall of the lower cover is provided with an internal thread that matches the external thread. In this way, the upper cover 901 and the lower cover 902 are screwed together. Figure 5 As shown, a number of ribs are fixedly provided in the upper cover 901, and the ribs include a center ring and a number of circumferentially arranged connecting plates. The center ring is fixedly connected to the inner wall surface of the lower cover 902 through the number of connecting plates. Screwing the upper cover 901 can press the filter membrane 8 against the annular flange on the inner wall surface of the lower cover 902, which can stably clamp the filter membrane 8. At this time, the center ring and the ribs are in contact with the filter membrane 8, so that the filter membrane 8 can be flattened, which is beneficial to improving the enrichment uniformity. At the same time, the structural design of the upper cover 901 can facilitate the staff to hold the center ring and the ribs to unscrew the upper cover 901 from the lower cover 902.

[0040] like Figure 3As shown, when the second driving unit 7 drives the filter membrane 8 to rotate to the enrichment component 5, the enrichment component 5 can enrich the soluble components in the atmosphere flowing through the filter membrane 8; specifically:

[0041] The enrichment assembly 5 includes an upper compression cover 501, a lower compression cover 502 and a third drive unit 3. The upper compression cover 501 is conical, and an upper sealing ring is provided on the bottom end surface of the upper compression cover 501. The top of the upper compression cover 501 is connected to an atmospheric cutter 200 through a hose 12. The atmospheric cutter 200 is a prior art and will not be described in detail here.

[0042] The lower pressing cover 502 is in an inverted cone shape. A sealing ring is provided on the top surface of the lower pressing cover 501 . The bottom of the lower pressing cover 502 is connected to the outside through the exhaust pipe 13 .

[0043] The third driving unit 3 can drive the upper pressing cover 501 and the lower pressing cover 502 to move closer or further away. Specifically, the third driving unit 3 includes a third motor. The rotor end of the third motor is fixed with a driving wheel. The driving wheels are respectively engaged with two racks arranged opposite to each other. The two racks are respectively connected to the upper pressing cover 501 and the lower pressing cover 502 through connecting arms. When the driving wheel rotates forward, the upper pressing cover 501 and the lower pressing cover 502 are close to each other. The upper pressing cover 501 and the lower pressing cover 502 can clamp the clamping assembly 9 up and down and form a closed chamber, so that the water-soluble components in the gas entering the closed chamber through the atmospheric cutter 200 are enriched on the filter membrane 8. At this time, the filter membrane 8 is arranged close to the upper pressing cover, which facilitates the enrichment of water-soluble substances thereon.

[0044] like Figure 5 As shown, a drying filter 14, a flow meter 15, a pressure-stabilizing filter 16 and a vacuum pump 17 are sequentially provided on the exhaust pipe 13 along the direction of the airflow, wherein the drying filter 14 and the pressure-stabilizing filter 16 are both vacuum filters, which are prior art and will not be described in detail here. The gas diffuses along a set path under the action of the vacuum pump 17. The drying filter 14 is used to dry the gas flowing through to avoid introducing water vapor into other components. The flow meter 15 is used to monitor the size of the airflow and is electrically connected to an external controller. The setting of the two filters can make the airflow more stable when the vacuum pump 17 is frequently started and stopped, which is beneficial to the enrichment of soluble substances on the filter membrane 8, thereby improving the detection accuracy.

[0045] like Figures 4-6 The device shown is for capturing and extracting water-soluble components in the atmosphere, and includes a movable seat 2, an elution component 11, a first drive unit and the above-mentioned capture device. The capture device is fixed on the movable seat 2 and can be moved up and down under the action of the first drive unit. Specifically, the first drive unit includes a first motor, which is fixedly arranged and drives the movable seat 2 to move up and down through a screw pair.

[0046] Among them, the hose 12 is designed to be tough, and when the movable seat 2 is displaced to the lower limit position under the action of the first driving unit and the filter membrane 8 is immersed in the eluent, the hose 12 is straightened, so that the airflow can enter the upper pressing cover 501 vertically, greatly reducing the residual soluble components on the inner wall of the hose 12, which is conducive to improving the detection accuracy.

[0047] The elution component 11 includes a first tank body 110, a second tank body 111 and an ultrasonic generator. The first tank body 110 is mounted outside the second tank body 111. The ultrasonic wave emitted by the ultrasonic generator can be transmitted to the eluent in the second tank body 111 through the liquid in the first tank body 110. In this embodiment, the ultrasonic generator has a power of 35W and an ultrasonic frequency of 40KHz. The arrangement of the first tank body 110 and the second tank body 111 in this application makes the caliber and size of the first tank body 110 more flexible, and can be adapted to the ultrasonic tank body in the existing technology, avoiding non-standard customization, which is conducive to reducing costs and having good flexibility of use. Among them, the first tank body 110 is respectively connected to a first water inlet and a first water outlet. The first water inlet is connected to the water source through a peristaltic pump, and a first drain valve is provided at the first water outlet. The liquid in the first tank body 110 can be replaced regularly, or the liquid in the first tank body 110 can be drained in time when the equipment is out of use.

[0048] The inner wall of the second cell body 111 mates with the outer edge of the clamping assembly 9 that holds the filter membrane 8. In this embodiment, the inner wall of the second cell body 111 and the outer wall of the clamping assembly 9 are spaced 0.5 to 5 mm apart. This allows for a sufficient liquid level to be maintained with a relatively small amount of eluent. Furthermore, the support plates on the turntable 6 facilitate immersion of the filter membrane 8 in the eluent, improving the elution efficiency and ensuring a sufficient concentration of soluble components in the extract. The second cell body 11 is connected to a second water inlet and a second water outlet. The second water inlet is connected to the eluent source via a metering pump, and the second water outlet is connected to an extract collection line, the end of which is connected to a collection bottle (not shown).

[0049] In addition, the liquid level in the first tank body 110 is not lower than the liquid level in the second tank body 111. In this embodiment, the liquid level in the first tank body 110 is 1 to 3 mm higher than the liquid level in the second tank body 111. This ensures good ultrasonic transmission effect and thus ensures elution effect.

[0050] In view of the good elution effect of the filter membrane in this application, multiple elutions can not only fully extract the soluble substances enriched on the filter membrane 8, but also clean the filter membrane 8, so that the filter membrane 8 after multiple elutions can meet the cleanliness requirements and avoid the generation of waste liquid. It should be emphasized that the extract finally obtained after multiple elutions in this application also has a suitable concentration of soluble components, which is convenient for measurement.

[0051] like Figure 5 and6 As shown, the outer cover of the capture and extraction device is provided with a box body 1, and an opening is provided on the side wall of the box body 1 facing the turntable, and a door panel 101 is hinged at the opening, and the door panel 101 includes a transparent window. A vertical panel is provided in the box body, and a notch 1021 for the movable seat to pass through is provided on the vertical panel. The vertical panel, the door panel 101 and the box body 1 together enclose an independent chamber 102 for accommodating the enrichment component 5, the turntable 6 and the elution component 11, so as to be relatively separated from other components.

[0052] like Figure 6 As shown, the outer cover of the movable seat 2 is provided with a dustproof cloth 18, and the outer edge of the dustproof cloth 18 is connected to the edge of the gap 1021 to cover the gap 1021, so that the movable seat 2 and the enrichment component 5 and turntable 6, elution component 11, first drive unit, second drive unit 7 and third drive unit 3 thereon can be further separated from other components.

[0053] The housing 1 is further enclosed by a housing 300. Housing 300 houses one or more of an air conditioner, sterilizer, and temperature sensor to create a favorable working environment, ensuring smooth operation of the device and preventing atmospheric fluctuations from affecting the capture and extraction process. Housing 300 also houses an extract collection device 400. This device is conventional and can be selected by those skilled in the art as needed. A detailed description thereof will not be given here.

[0054] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
