Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically a filter membrane supply module. Background Technology

[0002] In the field of air environment monitoring, the detection of the concentration of particulate matter (such as PM2.5 and PM10) in the atmosphere is a key link in assessing air quality. As the core component of the particulate matter sampling system, the sampling cutter uses a filter membrane with a specific pore size to intercept and collect particulate matter of the target size. The quality and supply efficiency of the filter membrane directly determine the accuracy of the sampling data and the continuity of the monitoring work.

[0003] Currently, mainstream air quality monitoring sampling cutters still rely on manual operation for filter membrane replacement and supply: after the sampling cycle ends, the operator must manually open the sealed chamber of the sampling cutter, remove the saturated waste filter membrane, then extract a single new filter membrane from the filter membrane storage box, manually adjust its position, and precisely place it on the filter membrane support; finally, the chamber is resealed to resume the sampling process. This operation mode has significant, unavoidable drawbacks: First, it is extremely inefficient and relies on manual operation. In large-scale air quality monitoring networks (such as multi-point monitoring stations covering an entire city), a single membrane replacement operation of a single sampling cutter takes 5-10 minutes. If the membrane replacement of dozens of devices needs to be completed, a large amount of manpower and time costs are required. At the same time, manual operation cannot provide 24-hour uninterrupted supply. If the membrane is not replaced in time after the sampling cycle ends, it will lead to interruption of monitoring data and affect the continuity of monitoring.

[0004] Secondly, it can easily lead to filter membrane contamination and positioning deviations, affecting detection accuracy. When manually removing the membrane, fingers directly touching the filter membrane can leave residues of grease, sweat, or environmental dust, causing filter membrane contamination. When placing the filter membrane, relying solely on manual visual alignment makes it difficult to ensure precise fit between the filter membrane and the cutter's air inlet and support base, which can easily result in misalignment or wrinkles. This can cause some particles to enter the detection unit directly without filtration, leading to distorted sampling data and affecting the accuracy of air quality assessment.

[0005] Third, it has poor adaptability to complex on-site environments. Air monitoring equipment is mostly deployed outdoors, facing complex environments such as low temperature, high humidity, and high dust levels: In low temperature environments, the operator's hand dexterity decreases, further prolonging the membrane replacement time; in high humidity environments, the filter membrane is prone to moisture and adhesion, and multiple membranes are easily pulled out when a single filter membrane is pulled out of the storage box, requiring repeated adjustments and increasing operational complexity; at the same time, outdoor dust can easily enter the cutter's interior during the manual opening of the sealed cavity, contaminating the detection components, and long-term accumulation will shorten the equipment's lifespan and increase the failure rate.

[0006] In addition, under the existing manual mode, filter membranes are mostly stored in ordinary boxes, which cannot achieve batch storage and orderly supply. When it is necessary to replace filter membranes of different specifications, the corresponding filter membrane box must be carried separately, which is cumbersome and easy to confuse, increasing the management difficulty of monitoring work.

[0012] Preferably, the first feeding mechanism further includes: A lifting positioning sensor component is installed on the lower side of the material bin. When the lifting frame moves to the bottom of the material bin, the lifting positioning sensor component can provide feedback to the control module.

[0013] Preferably, the rack includes: A frame is a vertically installed structure. The top plate is fixedly installed on the top of the upright; the top plate is a circular plate, and the discharge port of the second feeding mechanism is a through-hole opened on the top plate; the pusher plate is installed on the upper side of the top plate, and the lower surface of the pusher plate is in contact with the upper surface of the top plate.

[0015] Preferably, the feeding drive assembly includes: The feeding motor serves as the power source for the feeding drive assembly; The feeding rod is installed inside the upright of the material rack.

[0018] Compared with existing technologies, it has the following beneficial effects: In terms of efficiency and continuity, the module operates automatically through the coordinated operation of the first and second feeding mechanisms, eliminating the need for manual supervision: the material hopper pre-stores stacked filter membranes, which are then pushed one by one to the second feeding mechanism by the lifting structure, with rapid feeding coordinated by the pusher tray. This significantly reduces labor and time costs and ensures uninterrupted supply, avoiding data interruptions caused by untimely membrane replacement and guaranteeing data continuity.

[0020] In terms of storage management, the material warehouse enables batch storage and orderly supply of filter membranes, avoiding the chaos of manual boxed retrieval; some designs combine dual material warehouses with dual feed ports, which can supply filter membranes of different specifications separately, eliminating the need to carry corresponding filter membrane boxes separately, simplifying the process, avoiding specification confusion, and reducing the difficulty of filter membrane management in large-scale monitoring networks.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-6 This application provides the following technical solutions: A filter membrane supply module includes a first feeding mechanism 1 for supplying stacked filter membranes one by one; a second feeding mechanism 2 for receiving the filter membranes supplied by the first feeding mechanism 1 and then distributing and pushing them; and a filter membrane detection mechanism 3 for sensing feedback on whether the filter membranes have been supplied to the second feeding mechanism 2.

[0025] The first feeding mechanism 1 includes a material bin 11 and a lifting structure 12. The material bin 11 is a cylindrical cavity with a vertically aligned axis, capable of holding multiple vertically stacked filter membranes. The lifting structure 12 and the material bin 11 are paired, meaning one material bin 11 is paired with one set of lifting structures 12. Multiple sets of material bins 11 and lifting structures 12 can be configured according to actual needs. This solution uses a dual-material bin 11 arrangement side-by-side. The material bin 11 is open on one horizontal side and has a removable door, allowing filter membranes to be added to the bin. The lifting structure 12 can lift the stacked filter membranes in the material bin 11 upwards. The top of the material bin 11 is an open opening, which connects to the inlet of the second feeding mechanism 2. The lifting structure 12 lifts the filter membranes, achieving primary feeding of the filter membranes. The second feeding mechanism 2 uses a rotary feeding method, which drives the filter membrane at its inlet to rotate, moving the filter membrane to the outlet position, where it is then picked up by an external pickup mechanism. The pickup mechanism is not a key feature of this solution and can be used in testing equipment as needed; its structure will not be elaborated upon here. The filter membrane detection mechanism 3 is located on one side of the inlet of the second feeding mechanism 2. It provides feedback on whether the filter membrane at the inlet of the second feeding mechanism 2 is in position. The filter membrane detection mechanism 3 is electrically connected to an external control module to form a feedback loop.

[0026] Based on the above implementation scheme, the lifting structure 12 includes a lifting platform 121, a lifting frame 122, and a lifting drive assembly 13.

[0027] The lifting platform 121 is a frustum of a cone located within the material hopper 11, and is slidably connected to the inner wall of the material hopper 11. Stacked filter membranes can be placed on the upper side of the lifting platform 121. The lifting frame 122 can adopt various structural forms; in this design, it is a rectangular block, with the lower side of the lifting platform 121 and the upper side of one end of the lifting frame 122 fixedly connected. The lifting frame 122 is linked to the lifting drive assembly 13, which drives the lifting frame 122 to rise or fall vertically.

[0028] The lifting drive component 13 can take many different forms, as long as it can drive the lifting frame 122 to move. This solution provides the following implementation.

[0029] The lifting drive assembly 13 includes a lifting motor 131 fixedly mounted on one side of the material hopper 11, which serves as the power source for the lifting action. A vertical lifting rod 132, a lead screw, is mounted on one side of the lifting motor 131 and is rotatably connected to the external support structure. The lifting frame 122 and the lifting rod 132 are threadedly connected. The bottom end of the lifting rod 132 and the motor shaft of the lifting motor 131 are linked by a combination of a synchronous pulley and a synchronous belt, allowing the lifting motor 131 to drive the lifting rod 132 to rotate. The lifting motor 131 is a servo motor.

[0030] With this structure, when the lifting rod 132 rotates, combined with the sliding limit of the lifting platform 121 within the material bin 11, the lifting frame 122 can move up and down along the lifting rod 132. During feeding, the motor shaft of the lifting motor 131 rotates one preset number of revolutions each time, ensuring that the lifting platform 121 rises to the height of one filter membrane each time.

[0031] Based on the above implementation plan, see Figure 4 In order to confirm the initial position of the lifting platform 121 in the first feeding mechanism 1, the first feeding mechanism 1 also includes a lifting positioning sensor component 14. When the lifting frame 122 moves to the bottom of the material bin 11, the lifting positioning sensor component 14 can provide feedback to the control module.

[0032] The lifting positioning sensing assembly 14 includes a lifting sensor 141 and a lifting sensing element 142. The lifting sensor 141 is fixedly installed below the material bin 11 and is a photoelectric sensor. The transmitting and receiving ends of the lifting sensor 141 are horizontally arranged. The lifting sensing element 142 is fixedly installed at the bottom of the lifting frame 122. The lifting sensing element 142 is a baffle. When the lifting frame 122 moves to the bottom of its stroke, the lifting sensing element 142 can be inserted between the transmitting and receiving ends of the lifting sensor 141 to block the light signal between them, thereby realizing the position sensing of the lifting frame 122.

[0033] Based on the above implementation scheme, the second feeding mechanism 2 includes a material rack 21 and a pusher plate 22. The material rack 21 is fixedly installed on one side of the material bin 11, and includes a vertical frame and a top plate. The vertical frame is a vertically installed frame; the top plate is fixedly installed on the top of the vertical frame; the top plate is a circular plate, and the discharge port of the second feeding mechanism 2 is a through-hole opened on the top plate. Depending on actual needs, the number of discharge ports required by the externally connected equipment is determined accordingly. The pusher plate 22 is rotatably connected to the material rack 21, and the pusher plate 22 is provided with a filter membrane placement groove, which is a through-hole. The pusher plate 22 is located on the upper side of the top plate, and the lower surface of the pusher plate 22 is in contact with the upper surface of the top plate. The pusher plate 22 is linked with the feeding drive assembly 23 and is driven to rotate by the feeding drive assembly 23.

[0034] The top plate has a through slot for feeding into the material bin 11. After the filter membrane is pushed to the feeding port position of the top plate by the lifting structure 12, the filter membrane is also located in the filter membrane placement slot of the push plate 22. When the push plate 22 rotates, the filter membrane rotates with the push plate 22. Since the bottom plate does not have a slot, the filter membrane will not fall out. When the filter membrane placement slot of the push plate 22 rotates to the discharge port position of the top plate, the bottom of the top plate no longer supports the filter membrane. An external picking structure or receiving structure can be set at the discharge port position, and the filter membrane can be transferred to the external structure.

[0035] Based on the above implementation scheme, this solution provides a specific implementation of the feeding drive assembly 23, which includes a feeding motor 231 and a feeding rod. The feeding motor 231, as the power source of the feeding drive assembly 23, is fixedly installed on one side of the material rack 21. The feeding rod is installed inside the upright of the material rack 21 and is rotatably connected to the upright. The top end of the feeding rod passes through the top plate and is fixedly connected to the push plate 22. The feeding rod and the push plate 22 are coaxial; the feeding motor 231 and the feeding rod are linked, which can drive the feeding rod to rotate.

[0036] The feeding motor 231 and the feeding rod are linked by a combination of synchronous belt and synchronous pulley. Because the feeding rod is located inside the upright of the material rack 21, it is not shown in the attached drawing.

[0037] Based on the above implementation plan, see Figure 5 and Figure 6 The filter membrane testing mechanism 3 includes a testing frame 31, testing elements 32, and a testing sensor assembly 33. The testing frame 31 is positioned above the feed inlet of the second feeding mechanism 2; its structural form is not limited, as long as it can provide support. One testing element 32 is provided for each feed inlet of the second feeding mechanism 2. The testing element 32 and the testing frame 31 are vertically slidably connected, and the testing element 32 can rise or fall. A set of testing sensor assemblies 33 is provided for each testing element 32, and the testing sensor assembly 33 can feed back the position signal of the testing element 32 to the control module.

[0038] The detection component 32 includes a detection plate located at the bottom. The detection plate is a circular plate with an outer diameter smaller than the outer diameter of the filter membrane placement groove on the pusher plate 22 and smaller than the outer diameter of the material bin 11. A slide rod is fixedly installed on the upper part of the detection plate, and a horizontal plate is installed at the top of the slide rod. The slide rod and the detection frame 31 are slidably connected. A vertical detection baffle is installed on one side of the horizontal plate. The detection sensing assembly 33 includes a low-position detection sensor 331 and a high-position detection sensor 332. The low-position detection sensor 331 and the high-position detection sensor 332 correspond to the upper and lower stroke positions of the detection baffle on the upper part of the detection component 2, respectively. The low-position detection sensor 331 and the high-position detection sensor 332 are also photoelectric sensors, and they are fixedly connected to the detection frame 31. The low-position detection sensor 331 is used to provide feedback on the initial position of the detection component 32; the high-position detection sensor 332 is used to provide feedback on the position of the detection component 32 when there is a filter membrane at the feed inlet of the second feeding mechanism 2. In other words, when the detection plate of the detection component 32 is in the position waiting to be detected, the detection baffle is located at the low-position detection sensor 331. When the filter membrane lifts the detection plate of the detection component 32, the detection baffle is located at the high-position detection sensor 332, thereby realizing the sensing feedback on whether the filter membrane is in position.

[0039] Based on the above implementation scheme, to ensure that the detection element 32 can be lifted by the filter membrane and hover without falling, a damping ring is installed at the connection between the detection rod and the detection frame 31. Considering the reset of the detection element 32, that is, the need to return it to its initial position after the filter membrane supply is completed, this scheme also includes a detection reset assembly 34, which is linked with the detection element 32 and can move the detection element 32 to the initial position. The detection reset assembly 34 includes a reset motor 341 and a reset element 342. The motor shaft of the reset motor 341 is horizontally set, and the reset motor 341 is fixedly connected to the detection frame 31. The reset element 342 is a cam, and this scheme uses a semi-circular wheel. The reset element 342 is located on the upper side of the horizontal plate of the detection element. By rotating the reset element 342, its semi-circular structural part pushes the detection element 32 down to the initial position. Then the reset element 342 rotates until its semi-circular structural part faces upward, leaving clearance for the subsequent rise of the detection element 32.

[0040] Based on the above implementation scheme, and considering the confirmation of the position of the reset component 342, a reset sensor 343 is also provided. The reset sensor 343 is also fixed on the detection frame 31. A reset baffle is provided on the motor shaft of the reset component 342 or the reset motor 341. When the reset component 342 rotates to the point where its semi-circular structure faces upward, the reset baffle can be inserted between the signal transmitting end and the receiving end of the reset sensor 343 to trigger the sensing signal.
