Dry collection has certain requirements on the weight of particles and dust, and is not effective in collecting extremely small nano-scale dust. Due to the participation of water and other substances in wet collection, the state and purity of the powder after collection will be greatly affected. Summary of the invention

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] The object of the present invention is to provide a collection device for powder recovery to solve the problems existing in the above-mentioned prior art and to collect powder materials efficiently and without pollution.
[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] Embodiment 1
[0032] like Figures 1 to 4As shown, this embodiment provides a collection device 100 for powder recovery, which is particularly suitable for high-temperature nano powders. It can be used not only for the collection of high-temperature nano powders of quartz prepared by vapor deposition method, but also for the collection of high-temperature nano powders in other fields. Specifically, it includes a first collection structure 1 and a second collection structure 6. The first collection structure 1 is provided with an inlet 8 and an exhaust port 9. The inlet 8 is used to connect with the exhaust duct of the reaction chamber of the preparation structure. The exhaust port 9 is used to connect with the exhaust structure. A collection component is provided in the collection cavity of the first collection structure 1, and the collection component can swing. The exhaust port 9 of the first collection structure 1 is connected with the exhaust structure, so that the air containing the powder can enter the first collection structure 1 through the inlet 8 and form air flow. The air containing the powder enters the first collection structure 1 and contacts with the collection component. The powder is deposited on the collection component. When the powder reaches a certain amount, the powder falls into the second collection structure 6.
[0033] Specifically, in this embodiment, the first collecting structure 1 is made of quartz or metal material, and the collecting chamber in the first collecting structure 1 is divided into an upper collecting chamber 2 and a lower collecting chamber 3. The upper collecting chamber 2 is located above the lower collecting chamber 3, and the inlet 8 is located at the top of the upper collecting chamber 2. The exhaust port 9 is located in the lower collecting chamber 3 and on the corresponding side wall of the lower collecting chamber 3.
[0034] In this embodiment, the collection assembly includes a plurality of collection sheets 4, which are flat plate structures. The plurality of collection sheets 4 are arranged in parallel in a natural state. The natural state of the collection sheets 4 refers to a state without external force. The center line of the inlet 8 is parallel to the plane where the collection sheets 4 are located in the natural state. The upper end of the collection sheet 4 is connected to the first collection structure 1 through a rotating shaft 10, and the rotating shaft 10 is rotatably connected to the first collection structure 1. The collection sheet 4 and the rotating shaft 10 are both made of quartz. The powder enters the upper collection cavity 2 from the inlet 8 and contacts the collection sheet 4. The powder in the air slowly deposits on the collection sheet 4. The collection sheet 4 is used to perform preliminary deposition and collection of the powder.
[0035] This embodiment also includes a driving structure, which is used to drive the collection assembly to swing. The driving structure includes a power structure, a swing rod 12 and a connecting rod 11. The power structure is a structure that can achieve linear drive, such as a cylinder, a hydraulic cylinder or an electric telescopic rod. The power output end of the power structure is hinged to the swing rod 12, one end of the connecting rod 11 is hinged to the swing rod 12, and the other end of the connecting rod 11 is connected to the rotating shaft 10. The power structure drives the swing rod 12 to move, and drives the collection sheet 4 to swing back and forth through the connecting rod 11 and the rotating shaft 10.
[0036] In the present embodiment, an exhaust baffle 7 is provided in the first collecting structure 1, and the exhaust baffle 7 is located at the exhaust port 9. One end of the exhaust baffle 7 is hinged to the first collecting structure 1, and the exhaust baffle 7 is used to prevent the falling powder from being directly drawn away from the exhaust port 9 during exhaust. In the present embodiment, an elastic retaining structure is provided between the exhaust baffle 7 and the first collecting structure 1, and the elastic retaining structure is a spring.
[0037] In this embodiment, the second collection structure 6 is located below the first collection structure 1. The second collection structure 6 is used to finally collect and store the powder. A valve 5 is provided between the first collection structure 1 and the second collection structure 6. The valve 5 is used to seal and store the powder after collection. When the second collection structure 6 is filled with powder, the valve 5 can be closed and the second collection structure 6 can be replaced to achieve uninterrupted collection.
[0038] In this embodiment, the inlet 8 is used to dock with the exhaust duct of the preparation structure. After the excess high-temperature nano dust is discharged from the outlet of the exhaust duct, it enters the upper collection cavity 2 through the inlet 8. A swingable collection sheet 4 is provided inside the first collection structure 1. The collection sheet 4 is connected to the external swing rod 12 through the rotating shaft 10. The swing rod 12 moves after applying external force through the driving structure, so that the dust on the collection sheet 4 falls to the bottom through swinging, and enters the second collection structure 6 through the lower collection cavity 3 to complete the collection. The lower collection cavity 3 is provided with an exhaust port 9 for docking with the exhaust structure. When the exhaust structure is running, a low-speed air flow can be formed in the first collection structure 1, driving the dust flow to complete the deposition on the collection sheet 4. The front end of the exhaust port 9 is provided with an exhaust baffle 7 that forms an angle with the end face of the exhaust port 9, which is used to prevent the dust from being directly sucked away when it falls from the collection sheet 4. The exhaust baffle 7 can swing, and through the elastic holding structure, the angle can be changed according to the amount of dust on the exhaust baffle 7. A valve 5 is provided between the collecting lower cavity 3 and the second collecting structure 6. When the dust in the second collecting structure 6 is collected to a certain extent, the valve 5 is closed to replace the second collecting structure 6. After the replacement, the valve 5 is opened to continue collecting into the second collecting structure 6, so as to realize continuous collection. Similarly, the second collecting structure 6 itself is also provided with a valve.
[0039] When the collecting device 100 for powder recovery of this embodiment is in operation, the exhaust port 9 is connected to the exhaust structure, a low-speed air flow is formed in the first collecting structure 1, and suction is formed at the inlet 8, so that the air containing high-temperature nano dust is drawn out from the preparation structure into the upper collecting cavity 2, and the high-temperature dust in the air is deposited on the collecting sheet 4 through contact with the collecting sheet 4 which forms a certain angle (generally 5° to 30°) with the exhaust direction. The collecting sheet 4 is in a swinging state, and when a certain amount of dust is deposited, it will fall with the swing, and after falling, it will enter the second collecting structure 6 through the collecting lower cavity 3. During the falling process, some dust may directly enter the exhaust structure with the air and be sucked away, affecting the collection efficiency. Therefore, an exhaust baffle 7 is provided 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 the dust increases, 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 downward into the second collecting structure 6. At the same time, as the angle becomes smaller, the air flow rate through the exhaust baffle 7 becomes faster, and the dust on the exhaust baffle 7 is more likely to fall from the exhaust baffle 7 to the second collecting structure 6. When enough dust falls, the exhaust baffle 7 slowly rebounds, the flow rate decreases, and the dust falling from the upper cavity 2 continues to be deposited on the exhaust baffle 7, and this cycle is repeated to form continuous dust collection.
[0040] Embodiment 2
[0041] like Figures 5 to 8 As shown, the difference between this embodiment and the first embodiment is that this embodiment does not require a driving structure. In this embodiment, the center line of the inlet 8 is at an angle to the plane where the collecting sheet 4 is located in a 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 sheet 4 is located in a natural state. The air containing powder is blown toward the collecting sheet 4 at a low flow rate. Under the action of the air, the collecting sheet 4 can swing without external force to collect the powder, and the collected powder falls into the second collecting structure 6 as the collecting sheet 4 swings.
[0042] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
