Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an integrated device for the purification and recovery of volatile organic waste gas. Background Technology

[0002] The emission of volatile organic compounds (VOCs) is a common environmental problem in industrial production processes. These gases not only pollute the atmosphere but may also harm human health. Therefore, the effective purification and recycling of VOCs has become an important issue in the field of industrial environmental protection.

[0003] Currently, activated carbon is often used to purify volatile organic waste gas. However, after long-term use, activated carbon will become saturated and its purification capacity will decrease, requiring regular replacement. In practice, the waste gas delivery process often needs to be interrupted, making it impossible to achieve continuous operation of the equipment. This not only affects the efficiency of waste gas purification but also interferes with the continuity of waste gas purification. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an integrated device for the purification and recovery of volatile organic waste gas, which has the advantages of enabling filter box replacement without shutting down the machine and preventing waste gas leakage. This solves the problems in the prior art where filter box replacement requires machine shutdown and is prone to leakage, thus affecting purification efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an integrated device for purifying and recovering volatile organic waste gas, comprising a housing, with two symmetrical placement slots on the top of the housing, guide slots symmetrically arranged on both sides of the interior of the placement slots, and a movable hole on one side of the guide slot. A filter box is movably installed inside the placement slot, and compression blocks are fixedly installed on both sides of the filter box near the movable hole. An air inlet is provided on the side of the compression block near the movable hole, and the bottom of the compression block is inclined. Ventilation control components are provided on both sides of the filter box, and the movable hole works in conjunction with the ventilation control components. The ventilation control components consist of a ventilation pipe and a first spring. Two connecting pipes are fixedly installed on both sides of the housing, and the two connecting pipes are connected together through a gas passage switching component.

[0006] As a preferred technical solution of this utility model, the ventilation control component includes four ventilation pipes, which are movably installed inside the movable hole one. A conical limiting plate is fixedly installed at one end of the ventilation pipe near the connecting pipe, and several ventilation holes are equidistantly opened on the outer circumference of the ventilation pipe.

[0007] As a preferred embodiment of this utility model, the ventilation control component includes a first spring, which is fixedly installed on the side of the conical limiting plate near the housing, and the other end of the first spring is fixedly installed on one side of the housing. Two sealing rings are fixedly installed on the outer side of the ventilation pipe, and the ventilation pipe is disposed between the two sealing rings.

[0008] As a preferred technical solution of this utility model, the gas passage switching component includes a switching box, which is fixedly installed between two connecting pipes. An arc-shaped groove is provided on the top of the switching box, and two fixing holes are symmetrically provided on the bottom surface of the arc-shaped groove. A connecting plate is fixedly installed on one side of the switching box, and an air inlet pipe is fixedly installed on one side of the connecting plate.

[0009] As a preferred embodiment of the present invention, the gas passage switching assembly further includes a baffle plate, which is rotatably installed inside the switching box. Sealing gaskets are fixedly installed on both sides of the baffle plate, and a connecting rod is fixedly installed on the top of the baffle plate near one end, the connecting rod passing through the top of the switching box.

[0010] As a preferred embodiment of the present invention, the gas passage switching assembly further includes an L-shaped rod, which is fixedly installed on the outside of the connecting rod, and the other end of the L-shaped rod is movably sleeved inside the arc-shaped groove.

[0011] As a preferred embodiment of this utility model, the gas passage switching component further includes a mounting hole, which is located at the bottom of the L-shaped rod. A second movable hole is provided on the outer side of the L-shaped rod, and the second movable hole is connected to the mounting hole.

[0012] As a preferred technical solution of this utility model, the gas passage switching component further includes a plug rod, which is movably installed inside the mounting hole. The plug rod is used in conjunction with the fixing hole. An adjusting block is fixedly installed on the outside of the plug rod. The adjusting block is movably sleeved inside the second movable hole. A second spring is fixedly installed on the top of the plug rod. The top end of the second spring is fixedly installed with the inner top surface of the mounting hole.

[0013] The beneficial effects of this utility model are as follows: In this invention, when the filter box is inserted into the placement slot, the squeezing block squeezes the vent pipe in the ventilation control component, so that the vent hole on the vent pipe is connected to the air inlet hole of the squeezing block, allowing the exhaust gas to enter the filter box and be adsorbed and purified by activated carbon. When the filter box is removed, the vent pipe retracts under the action of the first spring, automatically sealing the vent hole to prevent exhaust gas leakage.

[0014] The gas path switching component can close the corresponding path by rotating the baffle when replacing a filter box, while keeping the other path open, ensuring that the exhaust gas treatment process can continue without stopping the machine, which greatly improves the exhaust gas treatment efficiency and equipment operation stability.

[0017] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figures 1-8 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 8 The present invention will be further described below.

[0019] An integrated device for purifying and recovering volatile organic waste gas includes a housing 1. Two placement slots are symmetrically opened on the top of the housing 1. Four pressure sensors 4 are symmetrically fixedly installed on the bottom surface of the placement slots. Guide slots 2 are symmetrically opened on both sides of the placement slots. A movable hole 3 is opened on one side of the guide slot 2. A filter box 5 is movably installed inside the placement slots. Squeezing blocks 6 are fixedly installed on both sides of the filter box 5 near the movable hole 3. An air inlet 7 is opened on the side of the squeezing block 6 near the movable hole 3. The bottom of the squeezing block 6 is sloped. Ventilation control components are provided on both sides of the filter box 5. The ventilation control components consist of a ventilation pipe 8 and a first spring 10. Two connecting pipes 13 are fixedly installed on both sides of the housing 1. The two connecting pipes 13 are connected together through a gas passage switching component.

[0020] In this implementation scheme, the housing 1 serves as the basic supporting structure of the device, providing installation space for each component. The pressure sensor 4 is electrically connected to an external PLC control module to monitor the weight change of the filter box 5 in real time. When the activated carbon in the filter box 5 adsorbs impurities in the exhaust gas to a preset weight, the pressure sensor 4 generates an electrical signal that is fed back to the PLC control module. Upon receiving this signal, the PLC control module triggers an alarm that emits a clear audible and visual alarm, reminding staff to replace the filter box 5 promptly. This ensures timely replacement of the filter box 5 to maintain exhaust gas treatment efficiency. The guide groove 2 guides the installation of the filter box 5, allowing it to be accurately and stably placed into the placement groove, improving installation convenience and stability. The filter box 5 is filled with activated carbon filter material. For the adsorption and purification of volatile organic waste gas, the activated carbon filter material is replaced regularly to ensure the continuous waste gas treatment effect. When the filter box 5 is installed, the extrusion block 6 extrudes the vent pipe 8, so that the vent hole 11 on the vent pipe 8 is connected to its own air inlet 7, establishing a passage for waste gas to enter the filter box 5. The inclined surface at the bottom facilitates smooth extrusion of the vent pipe 8. When the filter box 5 is installed, the extrusion block 6 extrudes the vent pipe 8, so that the vent hole 11 is connected to the air inlet 7, and the waste gas enters the filter box 5. When the filter box 5 is removed, it retracts under the action of the first spring 10, sealing the vent hole 11 to prevent waste gas leakage. When one of the filter boxes 5 is replaced, the gas passage switching component can close the corresponding passage while keeping the other passage open, ensuring that the waste gas treatment process can be carried out continuously without stopping the machine, thus improving the waste gas treatment efficiency and the stability of equipment operation.

[0021] Specifically, the ventilation control assembly includes four ventilation pipes 8, which are movably installed inside the movable hole 3. A conical limiting plate 9 is fixedly installed at one end of the ventilation pipe 8 near the connecting pipe 13, and several ventilation holes 11 are equidistantly opened on the outer circumference of the ventilation pipe 8.

[0022] In this embodiment, the vent pipe 8 is movably installed inside the movable hole 3, serving as the core channel for exhaust gas flow. Its movement, in conjunction with the compression block 6, enables the connection or disconnection between the vent hole 11 and the air inlet 7. The conical limiting plate 9 is fixed at one end of the vent pipe 8 near the connecting pipe 13, limiting the range of motion of the vent pipe 8 and providing an installation position for the first spring 10. The vent hole 11 is located on the outside of the vent pipe 8 and serves as the inlet for exhaust gas to enter the vent pipe 8. When the vent pipe 8 is compressed and moved, it moves towards the connecting pipe 13, causing the vent hole 11 to move from inside the movable hole 3 to inside the connecting pipe 13. Exhaust gas inside the connecting pipe 13 enters the vent pipe 8 through the vent hole 11 and then enters the filter box 5 for filtration through the air inlet 7 of the compression block 6.

[0023] Specifically, the ventilation control assembly includes a first spring 10, which is fixedly installed on the side of the conical limiting plate 9 near the housing 1. The other end of the first spring 10 is fixedly installed on one side of the housing 1. Two sealing rings 12 are fixedly installed on the outside of the ventilation pipe 8, and the ventilation pipe 8 is located between the two sealing rings 12.

[0024] In this embodiment, by fixing one end of the first spring 10 to the side of the conical limiting plate 9 near the housing 1 and the other end to the side of the housing 1, the vent pipe 8 is provided with a resetting force. After the filter box 5 is removed, the vent pipe 8 is driven to retract, causing the vent hole 11 to be hidden inside the movable hole 3. This, combined with the sealing ring 12, achieves passage closure. The sealing ring 12 is fixed to the outside of the vent pipe 8, and the vent pipe 8 is located between the two sealing rings 12. During the movement of the vent pipe 8, it tightly fits the inner wall of the movable hole 3, enhancing the sealing between the vent pipe 8 and the movable hole 3 and reducing exhaust gas leakage. When the vent hole 11 is hidden inside the housing 10, the vent pipe 8 retracts. Inside the movable hole 3, the sealing ring 12 near the conical limiting plate 9 will be movably fitted inside the movable hole 3. At this time, the exhaust gas will not enter the interior of the vent pipe 8 through the vent hole 11, nor will the exhaust gas leak into the interior of the housing 1 through the gap between the vent pipe 8 and the movable hole 3. When the vent pipe 8 is squeezed and the vent hole 11 moves out of the movable hole 3, the sealing ring 12 near the squeezing block 6 will be movably fitted inside the movable hole 3. At this time, the exhaust gas will not leak through the gap between the vent pipe 8 and the movable hole 3, so that the exhaust gas can only enter the interior of the vent pipe 8 through the vent hole 11.

[0025] Specifically, the gas passage switching assembly includes a switching box 14, which is fixedly installed between two connecting pipes 13. An arc-shaped groove 15 is provided on the top of the switching box 14, and two fixing holes 16 are symmetrically provided on the bottom surface of the arc-shaped groove 15. A connecting plate 20 is fixedly installed on one side of the switching box 14, and an air inlet pipe is fixedly installed on one side of the connecting plate 20.

[0026] In this embodiment, the switching box 14 is fixedly installed between two connecting pipes 13, providing space and basic structure for gas passage switching. The connecting pipes 13 connect the box body 1 and the switching box 14, serving as the channel for exhaust gas to enter the switching box 14. The two connecting pipes 13 correspond to the exhaust gas passages of different filter boxes 5. The switching box 14 enables the selection and switching of passages. The arc-shaped groove 15 is opened on the top of the switching box 14, providing a movement trajectory for the L-shaped rod 19, ensuring that the operating component can rotate along the arc path to achieve passage switching. It serves as a guide structure for the passage switching action. The fixing holes 16 are symmetrically opened on the bottom surface inside the arc-shaped groove 15, used to cooperate with the insertion rod 25. After the passage is switched to the target position, the operating component is locked to ensure the stability of the passage state after switching. The connecting plate 20 is fixed on one side of the switching box 14, providing an installation fulcrum for the air inlet pipe, enabling the air inlet pipe to be stably connected to the switching box 14. The air inlet pipe is installed on one side of the connecting plate 20, serving as the inlet for external exhaust gas to enter the switching box 14, transporting the volatile organic waste gas to be treated to the switching box 14.

[0027] Specifically, the gas passage switching assembly also includes a baffle 17, which is rotatably installed inside the switching box 14. Sealing gaskets are fixedly installed on both sides of the baffle 17, and a connecting rod 18 is fixedly installed on the top of the baffle 17 near one end, with the connecting rod 18 penetrating through the top of the switching box 14.

[0028] In this embodiment, by rotating the baffle 17 inside the switching box 14, the sealing gaskets on both sides can enhance the sealing with the inner wall of the switching box 14. By rotating, the corresponding passage can be closed or opened, controlling the flow path of the exhaust gas in the switching box 14. The connecting rod 18 is fixed to the top of the baffle 17 near one end and passes through the top of the switching box 14. It can transmit external operating force to the baffle 17, causing the baffle 17 to rotate inside the switching box 14.

[0029] Specifically, the gas passage switching assembly also includes an L-shaped rod 19, which is fixedly installed on the outside of the connecting rod 18, and the other end of the L-shaped rod 19 is movably sleeved inside the arc-shaped groove 15.

[0030] In this embodiment, by fixing the L-shaped rod 19 to the outside of the connecting rod 18 and movably fitting the other end into the arc-shaped groove 15, the connecting rod 18 can be rotated by moving within the arc-shaped groove 15, thereby controlling the direction of the baffle 17.

[0031] Specifically, the gas passage switching assembly also includes a mounting hole 22, which is located at the bottom of the L-shaped rod 19. A second movable hole 21 is provided on the outer side of the L-shaped rod 19, and the second movable hole 21 is connected to the mounting hole 22.

[0032] In this embodiment, the mounting hole 22 is opened at the bottom of the L-shaped rod 19 for installing the insertion rod 25. The second movable hole 21 is opened on the outside of the L-shaped rod 19 and is connected to the mounting hole 22, providing a movable channel for the adjusting block 24. By manually moving the adjusting block 24 upward, the insertion rod 25 can be moved upward, thereby unlocking the L-shaped rod 19.

[0033] Specifically, the gas passage switching assembly also includes a plug rod 25, which is movably installed inside the mounting hole 22. The plug rod 25 is used in conjunction with the fixing hole 16. An adjusting block 24 is fixedly installed on the outside of the plug rod 25. The adjusting block 24 is movably sleeved inside the movable hole 21. A second spring 23 is fixedly installed on the top of the plug rod 25. The top of the second spring 23 is fixedly installed with the inner top surface of the mounting hole 22.

[0034] In this embodiment, the insertion rod 25 is movably installed inside the mounting hole 22 and used in conjunction with the fixing hole 16. Under the action of the second spring 23, it can be inserted into the fixing hole 16 to lock the position of the L-shaped rod 19, thereby fixing the state of the baffle 17. The adjusting block 24 can pull it away from the fixing hole 16 to unlock it. The top end of the second spring 23 is fixed to the top surface inside the mounting hole 22, and the bottom end is fixed to the top of the insertion rod 25, providing a downward elastic force to push the insertion rod 25 into the fixing hole 16, thereby achieving automatic locking and ensuring the stability of the passage.

[0035] In summary: When using this utility model, external exhaust gas enters the switching box 14 through the air inlet pipe installed on one side of the connecting plate 20. At this time, manually moving the adjusting block 24 upward causes the insertion rod 25 to move upward and disengage from the fixing hole 16, compressing the second spring 23. Simultaneously, rotating the L-shaped rod 19 causes it to move within the arc-shaped groove 15. The L-shaped rod 19 drives the connecting rod 18 to rotate, which in turn drives the baffle 17 inside the switching box 14 to rotate. When the baffle 17 rotates to the appropriate position, under the elastic force of the second spring 23, the insertion rod 25 inserts into the fixing hole 16, locking the L-shaped groove 15 in place. The positions of rod 19 and baffle 17 allow exhaust gas to enter the interior of one of the connecting pipes 13. The filter box 5 is manually placed into the placement slot via guide groove 2. During placement, the compression blocks 6 on both sides of the filter box 5 compress the vent pipe 8. The vent pipe 8 moves within the movable hole 3 and stretches the first spring 10. At this time, the vent hole 11 on the outside of the vent pipe 8 moves out from the movable hole 3 into the interior of the connecting pipe 13, connecting with the air inlet hole 7 on the compression block 6. Simultaneously, the sealing ring 12 near one end of the compression block 6 is fitted into the movable hole 3, ensuring that exhaust gas only passes through the vent hole. Air enters the filter box 5 through the air inlet 7 and is purified by internal activated carbon adsorption. When the pressure sensor 4 detects that the filter box 5 has reached the preset weight due to the adsorption of waste gas, it sends a feedback signal to the external PLC control module. The alarm in the PLC control module emits a clear audible and visual alarm to remind the staff to replace it. At this time, manually move the adjusting block 24 so that it moves upward in the movable hole 21, causing the insertion rod 25 to compress the second spring 23 and disengage from the fixed hole 16, unlocking the L-shaped rod 19. Manually rotate the L-shaped rod 19 to another position, and the insertion rod 25 is released from the second spring 23. Under the action of 23, insert another fixed hole 16, lock the baffle 17, and switch the exhaust gas to enter another filter box 5 through another connecting pipe 13. Then, manually remove the saturated filter box 5. The first spring 10 pushes the vent pipe 8 to retract, and the vent hole 11 is hidden in the movable hole 3. The sealing ring 12 near the end of the conical limit plate 9 is fitted in the movable hole 3 to seal the passage and prevent exhaust gas leakage. Then, put the new filter box 5 through the guide groove 2. The squeezing block 6 of the new filter box 5 squeezes the vent pipe 8 again. Repeat the above ventilation process to achieve continuous exhaust gas treatment without stopping the machine.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
