Description

A waste gas collection device with flow rate regulation Technical Field

[0001] This utility model relates to the field of waste gas collection technology, specifically a waste gas collection device with flow rate adjustment. Background Technology

[0002] Authorization announcement number CN216955342U discloses an aerogel-based air collection device, which includes an aerogel-based gas collection column. The outlet end of the aerogel-based gas collection column is connected to a collector, and the output end of the collector is connected to a flow regulator through a connecting pipe. The flow regulator is connected to an air pump through a connecting pipe, and the output end of the air pump is connected to an exhaust gas processor. This technical solution can adjust the airflow by setting a flow regulator.

[0003] However, after a period of use, impurities from the exhaust gas tend to accumulate on the valve plate inside the flow regulator, which can affect the adjustment of the valve plate and thus affect the regulation of the flow rate. Since the flow regulator is connected to rigid pipes on both sides, the flanges on both sides of the flow regulator need to be forcefully detached from the flanges on the rigid pipes during disassembly, which is not only laborious but also causes wear and tear, making it inconvenient to clean the inside of the flow regulator. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a waste gas collection device with flow rate adjustment, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a waste gas collection device with flow rate regulation, comprising a collection pipe, a flow rate regulating valve, an inlet pipe, a pump, an air delivery pipe, and two telescopic components;

[0006] Both ends of the flow regulating valve are provided with flanges, and both ends of the flow regulating valve are respectively connected to the telescopic components on both sides.

[0007] One side of the telescopic component is connected to the collection tube, and the other side of the telescopic component is connected to the air inlet pipe. Both the air inlet pipe and the air delivery pipe are connected to the pump.

[0008] Both telescopic components are equipped with sealing components.

[0009] Preferably, the telescopic assembly includes a telescopic hose, and both ends of the telescopic hose are provided with flanges.

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

[0024] Referring to Figures 1-4, this utility model provides the following two technical solutions:

[0025] First implementation: A waste gas collection device with flow rate regulation, including a collection pipe 1, a flow rate regulating valve 2, an air inlet pipe 3, a pump 4, an air delivery pipe 5, and two telescopic components;

[0026] Both ends of the flow regulating valve 2 are provided with flange 6, and both ends of the flow regulating valve 2 are respectively connected to the expansion joints on both sides.

[0027] One side of the telescopic component is connected to the collection pipe 1, and the other side of the telescopic component is connected to the air inlet pipe 3. Both the air inlet pipe 3 and the air delivery pipe 5 are connected to the pump 4. The collection pipe 1 is fixed at the required location using existing technology and is used for the entry of exhaust gas. A valve can also be installed at the end of the collection pipe 1 to open and close the collection pipe 1.

[0028] Both telescopic components are equipped with sealing components, which can seal the telescopic components on both sides when the flow regulating valve 2 is removed for cleaning, so as to prevent foreign objects from entering and causing them to enter the pump 4 when pumping exhaust gas.

[0029] The telescopic assembly includes a telescopic hose 7, with flanges 8 at both ends of the telescopic hose 7. The two flanges 8 that are close to each other are connected to two flanges 6 by bolts, while the two flanges 8 that are far apart from each other are connected to the collection pipe 1 and the air inlet pipe 3 by bolts.

[0030] In order to provide support for the flow regulating valve 2, mounting rods 9 are provided at the bottom of the two flanges 2 8 that are far apart from each other. Movable rods 10 are slidably connected to the two mounting rods 9. Connecting plates 11 are connected to the two movable rods 10. The two connecting plates 11 are respectively connected to the two flanges 2 8 that are close to each other. This ensures that the telescopic hose 7 can move in a horizontal state.

[0031] In order to fix the length of the telescopic hose 7 and further ensure the stable use of the flow regulating valve 2, two fixing holes 12 are opened on the movable rod 10. A fixing rod 13 that passes through the mounting rod 9 is provided in one of the fixing holes 12. A return spring 14 is provided between the fixing rod 13 and the mounting rod 9. The return spring 14 drives the fixing rod 13 to be inserted into one of the fixing holes 12 to fix the movable rod 10.

[0032] The sealing assembly includes a rotating shaft 15 connected to the top of the movable rod 10 via a bearing. A sealing plate 16 is mounted on the rotating shaft 15, which can rotate the sealing plate 16 without affecting the flow regulating valve 2 during use. The bottom of the sealing plate 16 contacts the movable rod 10, providing support for the sealing plate 16 when not in use. Both ends of the two flanges 8 that are close to each other are provided with protrusions 17. Insert rods 18 are transversely inserted through the protrusions 17. Both ends of the sealing plate 16 are provided with through holes 19 that match the insert rods 18. Both insert rods 18 are connected to an arc-shaped rod 20, and a support spring 21 connected to the protrusions 17 is provided on the arc-shaped rod 20. The support spring 21 is used to drive the insert rods 18 into the through holes 19 to support the sealing plate 16, so that the sealing plate 16 is blocked by the insert rods 18 when it rotates, thus preventing it from rotating.

[0033] The second embodiment differs from the first embodiment in that a sealing ring 22 is provided on the top of the sealing plate 16.

[0034] Applying sealing ring 22 to flange 28 can improve the sealing effect with flange 28.

[0035] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0036] In use, open the valves on pump 4 and collection pipe 1. Exhaust gas enters through collection pipe 1, then passes through right telescopic hose 7, flow regulating valve 2, left telescopic hose 7, and inlet pipe 3 for extraction. Under the action of pump 4, it is sent to the next exhaust gas treatment process through delivery pipe 5. When it is necessary to disassemble flow regulating valve 2, first close the valves on pump 4 and collection pipe 1. Then, remove the bolts on flange 6. Then, insert fixing rod 13 into the two adjacent fixing holes 12. This allows the two movable rods 10 on both sides to slide in opposite directions within mounting rod 9. Thus, the two adjacent flanges 8 can be separated from flanges 6 on both sides, making it easy to remove flow regulating valve 2. After removal, pull the arc rod 20 with one hand and rotate the sealing plate 16 with the other hand to make the sealing ring 22 fit the flange 8. Then, release the arc rod 20, allowing the insertion rod 18 to be inserted into the through hole 19. This restricts the rotation of sealing plate 16 and seals the telescopic hoses 7 on both sides, preventing foreign objects from entering when cleaning flow regulating valve 2.
