Description

Technical Field

[0001] This invention relates to the field of fluidization technology, and in particular to a fluidization and transport apparatus. Background Technology

[0002] Fluidization of powders into solid particles exhibits a fluid-like state under the action of a fluid. When applied to the transport of ultralight powders, it can fully fluidize ultralight powder materials in a displaced gas atmosphere, temporarily forming a type of aerosol, so as to facilitate the efficient transport of ultralight powders to other storage containers or reaction vessels.

[0003] Existing technologies mainly use mechanical screws and mechanical vibrations to transfer powder materials. However, it is difficult to form a controllable, quantitative, and stable transfer flow for materials with low bulk density. It is also difficult to completely transfer ultralight powders from one container to another. Furthermore, during the transfer of ultralight powders, transfer blind spots are easily formed, resulting in transfer residues. Summary of the Invention

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The following is for reference. Figures 1-3 A fluidization and transport apparatus 100 according to an embodiment of the present invention is described.

[0029] Combination Figures 1-3 As shown, the fluidization and conveying device 100 according to an embodiment of the present invention mainly includes: a material tank 10 and a controller. The material tank 10 is provided with a containing space 11 for storing materials. This space ensures that the ultralight powder has sufficient space for fluidization within the fluidization and conveying device 100 during operation, guaranteeing reliable and stable operation of the device. In this embodiment, the ultralight powder is a powder material with a bulk density of 3-6 g / L or lower. The fluidization and conveying device 100 can fully fluidize the gas and ultralight powder within the containing space 11, forming an aerosol that facilitates the transport of the ultralight powder. This prevents the ultralight powder from bridging due to its special packing structure during transport, which could block the mechanical structure, resulting in low transport efficiency and residual material. Therefore, fluidizing the ultralight powder in the fluidization and conveying device 100 facilitates transport and improves transport efficiency.

[0030] Furthermore, the material tank 10 is provided with an inlet 12, an outlet 13, and an air inlet group 14, all of which are connected to the containing space 11. Specifically, the inlet 12 on the material tank 10 facilitates the entry of ultralight powder from outside the fluidization and conveying device 100 into the containing space 11. The outlet 13 on the material tank 10 facilitates the transfer of the fluidized ultralight powder from the outlet 13 to the container to be transferred, thus enabling the fluidization and conveying device 100 to have a conveying function and simplifying the transfer method of ultralight powder after fluidization by the fluidization and conveying device 100. The air inlet group 14 on the material tank 10 facilitates the entry of gas into the material tank 10, which facilitates the fluidization and conveying of the ultralight powder in the containing space 11 by the fluidization and conveying device 100, thereby improving the operational reliability of the fluidization and conveying device 100.

[0031] In addition, the feed inlet 12, the discharge outlet 13 and the air inlet group 14 are all connected to the containment space 11, which allows the ultralight powder and gas to be directly mixed in the containment space 11 after entering the material tank 10. This allows the ultralight powder to be directly fluidized and then transported in the containment space 11, thereby improving the transport efficiency of the fluidization and transport device 100.

[0032] Furthermore, the discharge port 13 is located at the bottom of the material tank 10, and there are multiple air inlet groups 14, which are spaced apart on the circumferential sidewall of the material tank 10. Specifically, the discharge port 13 is located at the bottom of the material tank 10 to facilitate the flow of fluidized ultralight powder from the material tank 10. The multiple air inlet groups 14 are spaced apart on the circumferential sidewall of the material tank 10, which provides a stable structural position for the multiple air inlet groups 14. The multiple air inlet groups 14 not only effectively improve the air intake efficiency of the fluidization and conveying device 100, but also improve the fluidization quality of the ultralight powder in the material tank 10.

[0033] Furthermore, the air inlet assembly 14 includes multiple air inlets 141, which are spaced apart along the length of the material tank 10. A portion of the air inlets 141 serves as a fluidization inlet, while the other portion serves as a transfer inlet. Specifically, the air inlet assembly 14 includes multiple air inlets 141, which are spaced apart along the length of the material tank 10. This improves the air intake efficiency of the air inlet assembly 14, making the air intake of the material tank 10 more uniform along its length, thereby enhancing the fluidization and transfer effect of the fluidization and transfer device 100. Additionally, the fact that a portion of the air inlets 141 serves as a fluidization inlet and the other portion as a transfer inlet ensures the normal operation of the fluidization and transfer function of the fluidization and transfer device 100.

[0034] Furthermore, the fluidization and transport apparatus 100 also includes a controller, which is configured to:

[0035] Control the closing of the discharge port 13 and the feeding of the inlet 12;

[0036] Control the opening of the fluidizing inlet to allow gas to enter the containing space 11 from the fluidizing inlet;

[0037] After the first predetermined time, the fluidized air inlet is closed.

[0038] The discharge port 13 is opened, and the air inlet is opened to allow gas to enter the receiving space 11 from the air inlet.

[0039] Specifically, the fluidization and conveying device 100 can realize the fluidization and conveying of ultralight powder by controlling the opening and closing of the discharge port 13, the feed port 12, the fluidization air inlet and the conveying air inlet through the controller. During the use of the fluidization and conveying device 100, the controller first controls the discharge port 13 to close and the feed port 12 to feed, so that the ultralight powder to be fluidized and conveyed can enter the receiving space 11 through the feed port 12, which can ensure that the fluidization and conveying device 100 feeds smoothly.

[0040] Furthermore, the controller opens the fluidization inlet, allowing gas to enter the containment space 11. The fluidization and transfer device 100 fluidizes the ultralight powder in the containment space 11. After a first predetermined time, the controller closes the fluidization inlet, completing the fluidization of the ultralight powder and forming a special aerosol in the containment space 11. In embodiments of the present invention, the first predetermined time can be adjusted within 10-20 minutes depending on the material mass of different ultralight powders.

[0041] Furthermore, during the ventilation and powder fluidization inside the fluidization and conveying device, after ensuring that the powder material has been fully fluidized, the controller controls the outlet 13 to open and the conveying inlet to open. Gas enters the containing space 11 from the conveying inlet, and the aerosol formed by the fluidized ultralight powder is conveyed from the outlet 13 to the container to be conveyed, thereby realizing the fluidization and conveying of ultralight powder by the fluidization and conveying device 100.

[0042] Therefore, by controlling the opening and closing states of the feed inlet 12, the discharge outlet 13 and the air inlet group 14 through the controller, the ultralight powder can be fluidized and conveyed, which can improve the conveying efficiency of the fluidization and conveying device 100 and prevent the generation of conveying blind spots and residual material.

[0043] Combination Figures 2-3As shown, a fluidization inlet is connected to a fluidization inlet valve 1411, and a transfer inlet is connected to a transfer inlet valve 1412. Specifically, the connection of the fluidization inlet valve 1411 to the fluidization inlet and the transfer inlet valve 1412 to the transfer inlet improves the reliability of gas flow or cutoff at the fluidization and transfer inlets, facilitates controller control of the opening and closing of the fluidization and transfer inlets, ensures the controllability of gas flow into the containment space 11 through the fluidization and transfer inlets, prevents backflow of gas after entering the containment space 11, and thus prevents leakage of ultralight powder from the fluidization and transfer device 100. This configuration improves the operational safety of the fluidization and transfer device 100, stabilizes the pressure inside the material tank 10, ensures the fluidization and transfer effect of the fluidization and transfer device 100, and guarantees the operational stability of the fluidization and transfer device 100.

[0044] Furthermore, the controller is configured to:

[0045] The fluidizing inlet is opened to allow gas to enter the containing space 11 from the fluidizing inlet, specifically as follows:

[0046] The fluidizing inlet valve 1411 is opened to allow gas to enter the containment space 11 from the fluidizing inlet.

[0047] The discharge port 13 and the air inlet are controlled to open, allowing gas to enter the receiving space 11 through the air inlet. Specifically:

[0048] The discharge port 13 is opened and the air inlet valve 1412 is opened, allowing gas to enter the receiving space 11 from the air inlet.

[0049] Specifically, when the controller controls the fluidization inlet to open and the gas enters the receiving space 11 from the fluidization inlet, the controller controls the fluidization inlet valve 1411 to open, and the gas enters the receiving space 11 from the fluidization inlet. When the controller controls the outlet 13 to open and the transfer inlet to open, and the gas enters the receiving space 11 from the transfer inlet, the controller controls the outlet 13 to open and the transfer inlet valve 1412 to open, and the gas enters the receiving space 11 from the transfer inlet. This configuration allows the controller to regulate the gas flow of the fluidization and transfer device 100 when it is operating the fluidization and transfer function by controlling the opening and closing of the fluidization inlet valve 1411 and the transfer inlet valve 1412. This ensures the reliability of the controller's control over the fluidization inlet and the transfer inlet, thereby improving the operational reliability of the fluidization and transfer device 100.

[0050] In an embodiment of the present invention, a gas outlet valve 17 is provided on the material tank 10. When the controller controls the fluidization inlet valve 1411 to open and allows gas to enter the containing space 11 from the fluidization inlet to fluidize the powder material, the gas outlet valve 17 is opened. The gas outlet valve 17 can ensure that the pressure in the containing space 11 of the material tank 10 is normal pressure or slightly positive pressure, which can balance the pressure of the material tank 10, discharge excess fluidization gas in the containing space 11, and prevent the powder in the containing space 11 from overflowing. When the powder in the fluidization and conveying device 100 is completely fluidized, the gas outlet valve 17 and the fluidization inlet valve 1411 are closed.

[0051] Combination Figures 1-2 As shown, there are at least three air inlet groups 14, which are spaced apart circumferentially around the material tank 10. Each air inlet group 14 includes at least one fluidization air inlet and one transfer air inlet. Specifically, the presence of at least three air inlet groups 14 in the fluidization and transfer device ensures that the number of air inlet groups 14 meets the requirements for fluidization and transfer air intake of the fluidization and transfer device 100. The spaced arrangement of the at least three air inlet groups 14 around the material tank 10 allows for more uniform air intake during the fluidization and transfer process. Each air inlet group 14 includes at least one fluidization air inlet and one transfer air inlet. Furthermore, in the air inlet group 14, the transfer air inlet 141 is located further away from the discharge port 13 than the fluidization air inlet 141. This ensures the reliability of the fluidization and conveying device 100 in introducing air into the material tank 10 during the fluidization and conveying process. It allows the fluidization and conveying device 100 to fluidize the ultralight powder into an aerosol and then convey the ultralight powder to the discharge port 13 through the conveying air inlet without disturbing the powder in the aerosol. This ensures the stability of the conveying of the ultralight powder after fluidization and improves the stability of the conveying function of the fluidization and conveying device 100.

[0052] Combination Figure 1 As shown, the fluidization and transfer device 100 also includes an annular air inlet pipe 20, which is arranged around the outer periphery of the material tank 10. A main air inlet 21 is provided on the annular air inlet pipe 20, and multiple fluidization air inlets and multiple transfer air inlets are selectively connected to the annular air inlet pipe 20. Specifically, the annular air inlet pipe 20 is arranged around the outer periphery of the material tank 10. The main air inlet pipe can control the flow of gas into the annular air inlet pipe 20, providing gas for the fluidization and transfer of the fluidization and transfer device 100. The multiple fluidization air inlets and multiple transfer air inlets are selectively connected to the annular air inlet pipe 20, allowing multiple fluidization air inlets or multiple transfer air inlets to simultaneously intake air during operation, facilitating controller control of the working state of the fluidization and transfer device 100.

[0053] Furthermore, the annular design can effectively equalize the pressure in the fluidization and conveying device 100, ensuring consistent input pressure at multiple fluidization inlets and multiple conveying inlets. This prevents blind spots and residues in the ultralight powder within the containment space 11 due to gas pressure differences, thereby improving the fluidization and conveying efficiency of the ultralight powder.

[0054] Combination Figure 1 and Figure 3 As shown, the annular intake pipe 20 is connected to the main intake valve 22;

[0055] The controller is specifically configured as follows:

[0056] The fluidizing inlet is opened to allow gas to enter the containing space 11 from the fluidizing inlet, specifically as follows:

[0057] The main intake valve 22 is opened and the input air pressure is 0.02-0.04 MPa. The fluidized intake valve 1411 is opened so that the gas enters the containment space 11 from the fluidized intake port.

[0058] The discharge port 13 and the air inlet are controlled to open, allowing gas to enter the receiving space 11 through the air inlet. Specifically:

[0059] The discharge port 13 is opened, the main air inlet valve 22 is opened and the input air pressure is 0.03-0.05 MPa, and the transmission air inlet valve 1412 is opened so that the gas enters the receiving space 11 from the transmission air inlet.

[0060] Specifically, the annular air inlet pipe 20 is connected to a main air inlet valve 22, which allows the controller to control the gas flow at the main air inlet 21, ensuring the controllability of gas flow into the annular air inlet pipe 20 through the main air inlet 21. Further, the controller controls the opening of the fluidizing air inlet, allowing gas to enter the containing space 11 from the fluidizing air inlet. Specifically, the controller opens the main air inlet valve 22 with an input air pressure of 0.02-0.04 MPa, and opens the fluidizing air inlet valve 1411, allowing gas to enter the containing space 11 from the fluidizing air inlet. This enables the ultralight powder to fluidize within the containing space 11, forming an aerosol. This configuration ensures the fluidization efficiency and effect of the fluidization and transport device 100.

[0061] Furthermore, the controller controls the opening of the discharge port 13 and the opening of the transmission air inlet, allowing gas to enter the containing space 11 from the transmission air inlet. Specifically, the controller controls the opening of the discharge port 13, controls the opening of the main air inlet valve 22, and sets the input air pressure to 0.03-0.05 MPa. The controller also controls the opening of the transmission air inlet valve 1412, allowing gas to enter the containing space 11 from the transmission air inlet. This allows the fluidization and transmission device 100 to transport the ultralight powder that has formed an aerosol. The ultralight powder can be transported from the discharge port 13 to the container to be transported. This configuration ensures the transmission efficiency and quality of the fluidization and transmission device 100.

[0062] Combination Figure 1 As shown, there are at least two main air inlets 21 and at least two main air inlet valves 22, with each of the at least two main air inlets 21 connected to the other at least two main air inlet valves 22 in a one-to-one correspondence. Specifically, by providing at least two main air inlets 21 on the annular air inlet pipe 20 and providing at least two main air inlet valves 22 in a one-to-one correspondence with each of the at least two main air inlets 21, the efficiency of gas entering the annular air inlet pipe 20 can be improved, the time for gas to flow from the main air inlet 21 to the fluidization air inlet or the transport air inlet can be shortened, thereby improving the working efficiency of the fluidization and transport device 100 and improving the quality of fluidization and transport of ultralight powder. The one-to-one correspondence between the main air inlet valves 22 and the main air inlets 21 ensures the controller's control over the gas flow of the main air inlets 21 and ensures the control sensitivity of the fluidization and transport device 100.

[0063] Combination Figure 1 and Figure 3 As shown, the fluidization and transfer device 100 also includes a vacuum pump 30 and a vacuum control valve 31, with the vacuum control valve 31 positioned between the vacuum pump 30 and the material tank 10. Specifically, by installing the vacuum pump 30 on the fluidization and transfer device 100, the pressure in the containing space 11 of the material tank 10 can be adjusted, ensuring a stable working pressure environment for fluidization and transfer in the fluidization and transfer device 100. This guarantees the fluidization effect and transfer efficiency of the fluidization and transfer device 100 and facilitates controller control of the operation of the fluidization and transfer device 100.

[0064] Furthermore, the vacuum control valve 31 is located between the vacuum pump 30 and the material tank 10, which allows the controller to control the effect of the vacuum pump 30 through the vacuum control valve 31. It also allows the controller to complete the gas replacement of the fluidization and conveying device 100 through the vacuum control valve 31. A filter element is provided between the vacuum control valve 31 and the material tank 10 to prevent ultra-light powder in the containment space 11 from entering the vacuum pump 30 and reducing the service life and working efficiency of the vacuum pump 30.

[0065] Furthermore, after controlling the outlet 13 to close and the inlet 12 to feed, the controller is also set to:

[0066] Control the vacuum pump 30 to open, and control the vacuum control valve 31 to open;

[0067] Once the vacuum gauge reading of vacuum pump 30 reaches the predetermined value, control vacuum control valve 31 to close, and control vacuum pump 30 to shut down.

[0068] Specifically, after the controller closes the discharge port 13 and feeds the material into the inlet 12, it controls the vacuum pump 30 to open and the vacuum control valve 31 to open. This allows the vacuum pump 30 to adjust the pressure in the containment space 11 to a vacuum state after the ultralight powder enters the containment space 11. This ensures that the pressure in the containment space 11 is stable and controllable during the fluidization and conveying process of the fluidization and conveying device 100, thereby ensuring the fluidization effect and conveying efficiency of the fluidization and conveying device 100 and ensuring the working efficiency of the fluidization and conveying device 100. After the vacuum gauge reading of the vacuum pump 30 reaches the predetermined value, the controller controls the vacuum control valve 31 to close and the vacuum pump 30 to close, allowing the controller to control the fluidization and conveying device 100 to complete one gas replacement.

[0069] Combination Figure 1 and Figure 3 As shown, the fluidization and conveying device 100 also includes a gas supply pipe 40, a gas supply control valve 41, and a pressure sensor 42. The gas supply pipe 40 and the pressure sensor 42 are mounted on the material tank 10, and the gas supply control valve 41 is mounted on the gas supply pipe 40. Specifically, by providing the gas supply pipe 40, the gas supply valve, and the pressure sensor 42 on the fluidization and conveying device 100, gas can be supplied to the containing space 11 through the gas supply pipe 40 after the vacuum pump 30 is activated. This prevents the ultralight powder from clogging the filter element when there is gas replacement in the containing space 11. It also allows the vacuum pump 30 to operate repeatedly during the operation of the fluidization and conveying device 100, reduces the maintenance of the fluidization and conveying device 100, and ensures the working efficiency of the vacuum pump 30.

[0070] In the embodiments of the present invention, the pressure sensor 42 has pressure display and sensing functions, and can realize automatic control and adjustment of the fluidization and transfer device 100. The pressure sensor 42 can also be a pressure gauge, which can display the real-time pressure of the storage space 11 inside the material tank 10, and can cooperate with the manual control of the material tank 10 to ensure the normal operation of the fluidization and transfer device 100.

[0071] Furthermore, when the vacuum gauge reading of the vacuum pump 30 reaches -0.07 to -0.1 MPa, the vacuum control valve 31 is closed. After the vacuum pump 30 is shut down, the controller is also set to:

[0072] Control the air supply valve 41 to open and the input air pressure to be -0.09-0.15 MPa;

[0073] When the pressure value of the pressure sensor 42 reaches 0.1 MPa, the air replenishment control valve 41 is closed.

[0074] Specifically, after the vacuum gauge reading of the vacuum pump 30 reaches -0.07 to -0.1 MPa, the vacuum control valve 31 is closed. This allows the gas supply pipe 40 to operate independently of the vacuum pump 30, ensuring that the controller can control the gas supply pipe 40 to supply gas to the containing space 11 without interfering with the operation of the vacuum pump 30. This guarantees the fluidization effect of the fluidization and transport device 100. After the vacuum pump 30 is closed, the controller opens the gas supply control valve 41, and the input gas pressure is -0.09 to -0.15 MPa. The pressure sensor 42 can receive the pressure changes within the containing space 11 during the gas supply process of the fluidization and transport device 100, and then transmit the received pressure signal to the controller. When the pressure value of the pressure sensor 42 reaches 0.1 MPa, the controller closes the gas supply control valve 41, thereby completing the gas supply work for fluidization and transport. In this embodiment of the invention, the vacuum control valve 31 is closed when the vacuum gauge reading of the vacuum pump 30 is -0.09 MPa.

[0075] In this embodiment of the invention, the controller controls the vacuum pump 30 to replace the gas in the containing space 11, and controls the gas supply pipe 40 to supply gas to the containing space 11. This process needs to be repeated at least three times to complete the atmosphere replacement in the fluidization and conveying device 100. This allows the fluidization and conveying device 100 to complete the fluidization of the ultralight powder. After fluidization, the fluidization and conveying device 100 can, as needed, transport the aerosol formed by the ultralight powder to other conveying containers in a pneumatic form. This process needs to be continuous to effectively avoid transport difficulties caused by the bridging effect of the ultralight powder material. Furthermore, during the operation of the fluidization and conveying device 100, the fluidization and conveying process of the ultralight powder material can be observed through the feed inlet 12. After the fluidization and conveying device 100 has completed its operation, the controller can simultaneously close all valves.

[0076] Combination Figures 1-2 As shown, an angle α is formed between the air inlet assembly 14 and the side wall of the material tank 10, where α satisfies the relationship: 30°≤α≤60°. Specifically, the angle formed between the air inlet assembly 14 and the side wall of the material tank 10 is between 30° and 60°, which can satisfy the requirement that the ultralight powder flows in a specific direction during fluidization, ensure the fluidization effect of the ultralight powder in the material tank 10, prevent the generation of blind spots and residues in the ultralight powder during fluidization and conveying, and thus improve the fluidization effect and conveying efficiency of the fluidization and conveying device 100.

[0077] Combination Figures 1-2As shown, the material tank 10 includes a cylindrical section 15 and a conical section 16. The conical section 16 is located below the cylindrical section 15, and its cross-sectional area gradually decreases. The discharge port 13 is located at the bottom of the conical section 16. Specifically, the material tank 10 is composed of a cylindrical section 15 and a conical section 16. The conical section 16 is located below the cylindrical section 15, and its cross-sectional area gradually decreases. The discharge port 13 is located at the bottom of the conical section 16. This arrangement not only simplifies the structure of the fluidization and conveying device 100, making it easy to assemble and suitable for the fluidization and conveying of various low bulk density powder materials, but also ensures the structural strength and structural integration of the fluidization and conveying device 100, guaranteeing its operational stability.

[0078] Furthermore, the air inlet assembly 14 is disposed on the side wall of the conical section 16, and an angle α is formed between the air inlet assembly 14 and the side wall of the conical section 16. Under the premise of ensuring the stable installation of the air inlet assembly 14 on the material tank 10, an angle is formed between the side walls of the air inlet assembly 14 and the material tank 10. This not only ensures the fluidization and conveying efficiency of the fluidization and conveying device 100, but also prevents the generation of conveying blind spots and residual materials in the fluidization and conveying process of ultralight powder, thereby improving the fluidization effect and conveying efficiency of the fluidization and conveying device 100.
