Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice powder recycling technology, and in particular to a collection device for powder recycling. Background Technology
[0002] In the material preparation process, there is often a problem of low material collection efficiency. For example, in the current chemical vapor deposition process for quartz production, only about 45% of the quartz powder generated by the reaction of raw materials is deposited on the surface of the target rod, while the rest of the powder is carried away by the equipment. This results in low raw material utilization and high cost. Therefore, effectively collecting and utilizing this part of the powder can improve the raw material utilization rate and reduce the raw material cost of the quartz manufacturing process.
[0003] Traditional powder collection methods are mainly divided into dry collection (gravity, inertia, cyclone, bag filter, electrostatic) and wet collection (spray, venturi, impact, water film). Dry collection requires a certain weight of particles and dust, and is not effective for collecting nanoscale dust with extremely small mass. Wet collection, due to the participation of substances such as water, will greatly affect the state and purity of the collected powder. Utility Model Content

Detailed Implementation
[0028] 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.
[0029] The purpose of this invention is to provide a collection device for powder recycling, which solves the problems existing in the prior art and can collect powder materials efficiently and without pollution.
[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] Example 1
[0032] like Figures 1 to 4As shown, this embodiment provides a collection device 100 for powder recovery, particularly suitable for high-temperature nanopowders. It can be applied not only to the collection of high-temperature nanopowders produced by chemical vapor deposition (CVD) for quartz, but also to the collection of high-temperature nanopowders in other fields. Specifically, it includes a first collection structure 1 and a second collection structure 6. The first collection structure 1 is equipped with an inlet 8 and an exhaust port 9. The inlet 8 is connected to the exhaust pipe of the reaction chamber used in the preparation of the structure, and the exhaust port 9 is connected to an exhaust system. A collection component is installed inside the collection chamber of the first collection structure 1, and the collection component is oscillating. The exhaust port 9 of the first collection structure 1 is connected to the exhaust system, allowing air containing powder to enter the first collection structure 1 through the inlet 8, creating airflow. The air containing powder enters the first collection structure 1 and contacts the collection component, causing the powder to deposit on the collection component. When a certain amount of powder is collected, it falls into the second collection structure 6.
[0033] Specifically, in this embodiment, the first collection structure 1 is made of quartz or metal material. The collection cavity inside the first collection structure 1 is divided into an upper collection cavity 2 and a lower collection cavity 3. The upper collection cavity 2 is located above the lower collection cavity 3. The inlet 8 is located at the top of the upper collection cavity 2. The exhaust port 9 is located in the lower collection cavity 3 and is located on the side wall corresponding to the lower collection cavity 3.
[0034] In this embodiment, the collection component includes several collection plates 4, each a flat plate. These plates are arranged parallel to each other in their natural state (unaffected by external forces). The centerline of the inlet 8 is parallel to the plane containing the collection plates 4 in their natural state. The upper end of each collection plate 4 is connected to the first collection structure 1 via a rotating shaft 10, which is rotatably connected to the first collection structure 1. Both the collection plates 4 and the rotating shaft 10 are made of quartz. Powder enters the upper collection chamber 2 through the inlet 8 and comes into contact with the collection plates 4. The powder in the air slowly deposits on the collection plates 4, which are used for initial deposition and collection of the powder.
[0035] This embodiment also includes a drive structure for driving the collecting assembly to swing. The drive structure includes a power structure, a swing arm 12, and a connecting rod 11. The power structure is a cylinder, hydraulic cylinder, or electric telescopic rod, etc., capable of linear drive. The power output end of the power structure is hinged to the swing arm 12, one end of the connecting rod 11 is hinged to the swing arm 12, and the other end of the connecting rod 11 is connected to the rotating shaft 10. The power structure drives the swing arm 12 to move, which in turn drives the collecting plate 4 to swing back and forth via the connecting rod 11 and the rotating shaft 10.
[0036] In this embodiment, a suction baffle 7 is provided inside the first collecting structure 1. The suction baffle 7 is located at the suction port 9. One end of the suction baffle 7 is hinged to the first collecting structure 1. The suction baffle 7 is used to prevent the falling powder from being directly drawn away from the suction port 9 during suction. In this embodiment, an elastic retaining structure is provided between the suction baffle 7 and the first collecting structure 1. The elastic retaining structure is a spring.
[0037] In this embodiment, the second collecting structure 6 is located below the first collecting structure 1. The second collecting structure 6 is used for the final collection and storage of the powder. A valve 5 is provided between the first collecting structure 1 and the second collecting structure 6. The valve 5 is used for sealing and storing the collected powder. When the second collecting structure 6 is full of powder, the valve 5 can be closed and the second collecting structure 6 can be replaced to achieve uninterrupted collection.
[0038] In this embodiment, inlet 8 is used to connect to the exhaust duct of the fabrication structure. Excess high-temperature nanoparticles are discharged from the outlet of the exhaust duct and enter the upper collection chamber 2 through inlet 8. The first collection structure 1 is equipped with a swingable collection plate 4. The collection plate 4 is connected to an external swing rod 12 through a rotating shaft 10. The swing rod 12 moves after an external force is applied by a driving structure, causing the dust on the collection plate 4 to fall downwards through the swinging motion and enter the second collection structure 6 through the lower collection chamber 3 for collection. The lower collection chamber 3 is equipped with an exhaust port 9 for connecting to the exhaust structure. When the exhaust structure is running, a low-speed airflow can be formed in the first collection structure 1, driving the dust to flow and complete the deposition on the collection plate 4. The exhaust port 9 is equipped with an exhaust baffle 7 at the front end, forming an angle with the end face of the exhaust port 9, to prevent the dust from being directly sucked away when it falls from the collection plate 4. The exhaust baffle 7 can swing, and through an elastic holding structure, the angle can be changed according to the amount of dust on the exhaust baffle 7. A valve 5 is installed between the lower collection chamber 3 and the second collection structure 6. When the dust collected in the second collection structure 6 reaches a certain level, the valve 5 closes to replace the second collection structure 6. After replacement, the valve 5 is opened to continue collecting dust into the second collection structure 6, thus achieving continuous collection. Similarly, the second collection structure 6 itself is also equipped with a valve.
[0039] When the collection device 100 for powder recovery in this embodiment is running, the exhaust port 9 is connected to the exhaust structure, forming a low-speed airflow in the first collection structure 1 and forming a suction force at the inlet 8, drawing the air containing high-temperature nanoparticles from the preparation structure into the upper collection chamber 2. The air comes into contact with the collection plate 4, which forms a certain angle (generally 5° to 30°) with the exhaust direction. The high-temperature dust in the air will be deposited on the collection plate 4. The collection plate 4 is in a swinging state. When a certain amount of dust is deposited, it will fall off with the swinging motion. After falling off, it enters the second collection structure 6 through the lower collection chamber 3. During the falling process, some dust may be drawn directly into the exhaust structure with the air and affected the collection efficiency. Therefore, an exhaust baffle 7 is set at the exhaust port 9. The exhaust baffle 7 maintains a certain angle with the end face of the exhaust port 9 through an elastic retaining structure. As more and more dust accumulates, the angle between the exhaust baffle 7 and the end face of the exhaust port 9 becomes smaller and smaller. Therefore, the dust on the exhaust baffle 7 will fall down into the second collection structure 6. At the same time, as the angle decreases, the airflow velocity through the exhaust baffle 7 increases, and the dust on the exhaust baffle 7 falls more easily into the second collection structure 6. When enough dust has fallen, the exhaust baffle 7 slowly rebounds, the flow velocity decreases, and the dust falling from the upper cavity 2 continues to deposit on the exhaust baffle 7. This cycle continues, forming a continuous dust collection.
[0040] Example 2
[0041] like Figures 5 to 8 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment does not require a driving structure. In this embodiment, the centerline of the inlet 8 is at an angle to the plane where the collecting plate 4 is located in its natural state; that is, the flow direction of the air containing powder at the inlet 8 is at an angle to the plane where the collecting plate 4 is located in its natural state. The air containing powder is blown towards the collecting plate 4 at a low flow rate. Under the action of the air, the collecting plate 4 can swing without external force to collect the powder, and the collected powder falls into the second collecting structure 6 as the collecting plate 4 swings.
[0042] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
