[0001] This invention relates to the field of waste recycling technology, and in particular to a waste recycling device for processing thin films with multi-level nanoporous structures. Background Technology

[0002] As high-end functional materials, the recycling of waste materials during the production process of multi-level nanoporous thin films is crucial for reducing costs and achieving resource recycling. Currently, the industry commonly uses negative pressure pipeline systems for centralized adsorption and collection of processing waste.

[0003] While collecting target waste, negative pressure adsorption systems inevitably suck in large foreign objects from the surrounding environment, such as detached tool parts, worn metal fragments, cable ties, or wads of paper. Traditional negative pressure adsorption pipelines are merely transport channels and cannot perform preliminary screening of waste, increasing the difficulty and cost of subsequent waste recycling. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waste recycling device for processing thin films with multi-level nanoporous structures includes a suction plate with a negative pressure pipe connected to it. The recycling net is installed inside the negative pressure pipe via a silicone ring; The flow guide is installed inside the negative pressure pipeline and located behind the recycling net. The flow guide has a flow guide ramp inside, and a negative pressure port and a one-way valve are respectively provided at the end of the flow guide ramp. The airbag is installed at the top of the negative pressure pipeline, the other end of the one-way valve is connected to the airbag, and a solenoid valve is installed at the bottom of the airbag facing the recycling net. The regulating plate is located on the negative pressure pipeline and moves vertically. The regulating plate has a through cavity and a vertical cavity. The guide and the air bag both pass through the vertical cavity, and the height of the regulating plate is adjusted by the expansion state of the air bag.

[0006] In addition, a preferred structure is that a material discharge chamber is provided on the negative pressure pipe in front of the recycling net, a detachable storage bin is mounted on the bottom of the material discharge chamber on the negative pressure pipe via a mounting seat, and an outer shell is installed on the outside of the negative pressure pipe.

[0007] In addition, a preferred structure is that an adjustment cavity is provided on the negative pressure pipe behind the material discharge chamber, the adjustment plate is adapted to move vertically within the adjustment cavity, and guide members for guiding the adjustment plate are fixedly provided on the upper and lower sides of the adjustment cavity.

[0008] In addition, a preferred structure is that a connecting frame is fixedly provided at the bottom of the adjusting plate, the other end of the connecting frame extends into the storage compartment and is fixedly connected to the sealing component, and the sealing component is adapted to seal the material discharge cavity.

[0009] In addition, a preferred structure is that a sealing groove is adapted to the movable position of the connecting frame on the side wall of the storage compartment, and side blocks for sealing are adapted to be provided on both sides of the sealing groove on the connecting frame, and sealing plates for sealing are fixedly provided on both sides of the adjusting plate on the storage compartment.

[0010] In addition, a preferred structure is that the side of the guide member facing the recycling net is set as an air inlet, a dustproof net is installed on the air inlet, and the air inlet gradually narrows.

[0011] In addition, the preferred structure is that the flow guide slope is inclined upward, a negative pressure port is opened on the side of the flow guide away from the air inlet, a one-way valve is installed on the side of the flow guide located at the negative pressure port, and the one-way valve is inclined in accordance with the flow guide slope.

[0012] Furthermore, in a preferred configuration, the regulating plate has a through cavity and a vertical cavity extending laterally, the through cavity being adapted to the inner diameter of the negative pressure pipe, and the vertical cavity and the through cavity being adapted to communicate with each other.

[0013] Furthermore, in a preferred configuration, the airbag passes through the vertical cavity, expands or contracts vertically, and a top plate is fixedly provided on the top of the airbag.

[0014] Furthermore, in a preferred configuration, when the adjusting plate is positioned above, the passage cavity is adapted and aligned with the negative pressure pipe; when the adjusting plate is positioned below, the adjusting plate blocks the negative pressure pipe.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] See Figure 1-2 One end of the negative pressure pipe 11 is connected to a suction plate 1, and the other end is connected to a waste bin. A negative pressure is provided by a drive component inside the waste bin, allowing the suction plate 1 to adsorb the material, which then enters the waste bin through the negative pressure pipe 11. It is worth noting that the suction plate 1 can be mounted on a movable component and connected to the negative pressure pipe via a corrugated pipe to enable movable material suction from the suction plate 1. These are all existing technologies and will not be elaborated further.

[0020] A housing 12 is installed in the middle of the negative pressure pipe 11. The housing 12 is equipped with a filter structure to perform preliminary filtration of waste materials.

[0021] See Figure 2-6A material discharge chamber 111 is provided on the negative pressure pipe 11 in front of the recycling net 3. A detachable collection bin 2 is mounted on the bottom of the material discharge chamber 111 on the negative pressure pipe 11 via a mounting base 13. The collection bin 2 is mounted on the bottom of the mounting base 13 by screws. The collection bin 2 can be used to collect large-diameter materials filtered from the recycling net 3.

[0022] A sealing element 54 is vertically movable inside the material discharge chamber 111, which allows the material discharge chamber 111 to be opened and closed. The sealing element 54 is fixedly connected to the adjusting plate 5 via the connecting frame 53, so that the sealing element 54 can move synchronously with the adjusting plate 5.

[0023] A sealing groove 21 is provided on the side wall of the storage compartment 2 to accommodate the movable position of the connecting frame 53. Side blocks 531 for sealing are fitted on both sides of the sealing groove 21 on the connecting frame 53. The sealing groove 21 and side blocks 531 prevent leakage of waste materials stored in the storage compartment 2. This is existing technology and will not be described in detail.

[0024] The negative pressure pipe 11 has an adjustment cavity 112 located behind the material discharge cavity 111. The adjustment plate 5 is adapted to be vertically movable within the adjustment cavity 112. Guide members 113 are fixedly installed on the upper and lower sides of the adjustment cavity 112, and the guide members 113 are adapted to the vertical cavity 52, so that the adjustment plate 5 can be guided and moved by the guide members 113.

[0025] Sealing plates 22 are fixedly installed on both sides of the regulating plate 5 on the storage compartment 2 for sealing. The sealing plates 22 can seal the regulating cavity 112 to ensure the airtightness of the negative pressure pipeline 11. This is existing technology, so it will not be described in detail.

[0026] See Figure 5-11 A recycling net 3 is installed inside the negative pressure pipe 11. A silicone ring 31 is fitted on the outside of the recycling net 3, and the recycling net 3 is connected to the negative pressure pipe 11 through the silicone ring 31. The silicone ring 31 allows the recycling net 3 to vibrate when subjected to external force, easily shaking off the material trapped on the recycling net 3.

[0027] The flow guide 4 is installed on the negative pressure pipe 11 and located behind the recycling net 3. An air inlet 42 is set on the side of the flow guide 4 facing the recycling net 3, and a dustproof net 41 is installed on the air inlet 42. The dustproof net 41 prevents solid objects in the airflow from entering the flow guide 4, thus ensuring the service life of the flow guide 4. During long-term use, the dustproof net 41 needs to be maintained and cleaned regularly.

[0028] It is worth noting that the recycling net 3 is a filter with a relatively large filter diameter. By designing the recycling net 3, large-diameter impurities in the airflow can be separated from small-diameter waste particles, thus achieving the interception of large-diameter impurities. The dustproof net 41 has a smaller filter diameter. By designing the dustproof net 41, all solid matter in the airflow can be intercepted, preventing dust from entering the guide component 4, thereby improving the service life of the guide component 4. Furthermore, the dustproof net 41 is designed with a slightly convex outward arc surface, which ensures that the solid waste intercepted on the dustproof net 41 will not remain on the dustproof net 41 for a long time, but will gradually leave with the airflow.

[0029] The guide member 4 has a guide ramp 43 located behind the air inlet 42. The guide ramp 43 is inclined upwards, and the one-way valve 45 is inclined in the direction of the guide ramp 43. This can guide the airflow so that the airflow in the guide member 4 is blown into the one-way valve 45.

[0030] A negative pressure port 44 is provided on the side of the guide member 4 away from the air inlet 42. When the regulating plate 5 blocks the negative pressure pipe 11, negative pressure can be provided through the negative pressure port 44. At this time, the airflow passes through the guide member 4, and a strong airflow is generated to enter the one-way valve 45 to inflate the airbag 6.

[0031] The regulating plate 5 has a through cavity 51 and a vertical cavity 52 extending horizontally through it. The through cavity 51 is adapted to the inner diameter of the negative pressure pipe 11, and the vertical cavity 52 is adapted to communicate with the through cavity 51. When the regulating plate 5 is in the upper position, the through cavity 51 is adapted to and aligned with the negative pressure pipe 11. When the regulating plate 5 is in the lower position, the regulating plate 5 blocks the negative pressure pipe 11.

[0032] The airbag 6 passes through the vertical cavity 52, and expands or contracts vertically. A top plate 61 is fixedly installed on the top of the airbag 6. The outlet of the one-way valve 45 is connected to the airbag 6, so that the airbag 6 can be inflated through the one-way valve 45. When the airbag 6 is inflated, the top plate 61 on the top of the airbag 6 moves upward, thereby lifting the adjusting plate 5 upward.

[0033] A solenoid valve 62 is installed at the bottom of the airbag 6, and a nozzle is mounted on the solenoid valve 62, which is positioned facing the recovery net 3. When the solenoid valve 62 is opened, the airflow inside the airbag 6 is ejected through the nozzle, thereby purging the recovery net 3 and achieving backflushing of the recovery net 3. Furthermore, the nozzle is designed with a relatively high flow rate to ensure that the gas inside the airbag 6 can be ejected in a short time.

[0034] It is worth noting that all moving parts described in this application are equipped with seals to ensure the airtightness of the negative pressure pipe 11. This is prior art and will not be elaborated further.

[0035] In this embodiment, during the waste recycling process, the waste is adsorbed by the suction plate 1, and then enters the negative pressure pipe 11, where it is filtered by the recycling net 3. Membrane waste can pass through the recycling net 3, while other large particles are retained by it. Finally, the membrane waste enters the waste bin through the negative pressure pipe 11, thus achieving the collection of membrane waste. This separation of waste ensures the effectiveness of subsequent membrane waste recycling.

[0036] Furthermore, after the device has been working for a period of time, some other waste materials will be intercepted on the recycling net 3. At this time, the recycling net 3 can be backflushed to clean it.

[0037] When cleaning the recycling net 3, simply open the solenoid valve 62 and close the negative pressure drive component in the negative pressure pipeline 11. At this time, the gas in the airbag 6 can be sprayed out through the nozzle on the solenoid valve 62, thereby achieving backflushing of the recycling net 3 through the sprayed gas, thus cleaning the recycling net 3.

[0038] When gas is ejected from the airbag 6, the adjusting plate 5 moves downward under its own weight, providing pressure on the airbag 6 to increase the flow rate of the gas ejected from the nozzle. The top plate 61 at the top of the airbag 6 is made of rigid material, so the airbag 6 can be compressed evenly when the adjusting plate 5 moves downward.

[0039] Furthermore, after the regulating plate 5 moves downward, it can block the negative pressure pipe 11, allowing airflow to pass only through the guide member 4. At the instant the regulating plate 5 blocks the negative pressure pipe 11, the airflow generated by the negative pressure collides with the regulating plate 5, creating an air hammer effect. This collision between the airflow and the regulating plate 5 vibrates the recycling net 3, and the silicone ring 31 on the recycling net 3 further facilitates vibration. This vibration causes the remaining waste material intercepted by the recycling net 3 to fall off.

[0040] Furthermore, as the adjusting plate 5 moves downward, it can simultaneously move the sealing component 54 downward via the connecting frame 53. This releases the sealing effect of the sealing component 54 on the discharge chamber 111, opening the discharge chamber 111. The remaining large-diameter waste particles shaken off the recycling net 3 can then enter the collection bin 2 through the discharge chamber 111 for collection. This separation of waste ensures effective recycling of the film waste.

[0041] Furthermore, after cleaning the recycling net 3, simply close the solenoid valve 62 and simultaneously open the negative pressure drive component in the negative pressure pipe 11. At this time, negative pressure airflow is generated again in the negative pressure pipe 11. However, since the negative pressure pipe 11 is blocked by the regulating plate 5, only the negative pressure port 44 can guide the airflow, so the airflow can only pass through the guide member 4.

[0042] At this time, the airflow in the negative pressure pipe 11 enters the guide member 4 and is guided by the guide ramp 43, and finally passes through the negative pressure port 44. The airflow guided by the guide ramp 43 can rush towards the one-way valve 45, which allows some airflow to enter the airbag 6 through the one-way valve 45 to inflate the airbag 6.

[0043] As the airbag 6 inflates, it gradually lifts the top plate 61 upwards, causing the adjusting plate 5 to move upwards synchronously. Once the airbag 6 is fully inflated, the adjusting plate 5 moves to its highest point, at which point the through cavity 51 on the adjusting plate 5 aligns again with the negative pressure pipe 11, fully opening the negative pressure pipe 11 once more. Furthermore, as the adjusting plate 5 moves, the connecting frame 53 drives the sealing component 54 to move upwards synchronously, again sealing the material discharge chamber 111 and closing it. This allows for the resetting of all components, enabling the separation and collection of film waste once more.

[0044] It is worth noting that as the regulating plate 5 moves upward, the negative pressure pipes 11 on both sides of the guide member 4 gradually overlap with the through cavity 51. This causes the negative pressure pipes 11 on both sides of the guide member 4 to gradually open, which reduces the flow rate and velocity entering the guide member 4. However, at this time, the airflow velocity inside the guide member 4 is still sufficient to drive the gas through the one-way valve 45 and inflate the airbag 6. When the airbag 6 is fully inflated, the airflow velocity inside the guide member 4 will be less than the through pressure of the one-way valve 45, and thus can no longer enter the airbag 6.

[0045] Furthermore, when the solenoid valve 62 is opened, the gas inside the airbag 6 can be quickly released through the nozzle to ensure that the regulating plate 5 can fall quickly. At this time, the airflow in the negative pressure pipe 11 hits the regulating plate 5, which can then vibrate the recycling net 3 through the air hammer effect, thereby cleaning the recycling net 3.

[0046] In this invention, the linkage between the recycling net 3, the guide 4, the regulating plate 5 and the airbag 6 set in the negative pressure pipe 11 can realize the screening of film waste and other waste materials and the automatic cleaning of the recycling net 3. This method can realize the sorting of waste materials during the recycling process to ensure the recycling effect of waste materials, thereby reducing the difficulty and cost of recycling waste materials in the subsequent process.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
