Description

Technical Field

[0001] This utility model belongs to the field of aluminum powder mixing technology, and specifically relates to a high-efficiency aluminum powder mixer. Background Technology

[0002] In many industrial applications, aluminum powder needs to be mixed to prepare aluminum paste, and this mixing is generally achieved by stirring equipment.

[0003] However, existing mixing equipment is often inefficient, resulting in long production cycles. In addition, some mixing equipment has open hoppers, which generate a lot of dust during the mixing process, posing a threat to the environment and the health of operators, and also causing waste of materials. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a high-efficiency aluminum powder mixer.

[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used:

[0006] A high-efficiency aluminum powder mixer includes a frame, on which a material hopper and a mixing drum are mounted. The material hopper has an open mixing chamber at the top. The mixing drum is mounted on the frame via a mixing drum lifting structure, which allows it to descend and move its mixing components into the mixing chamber and close the open opening. The mixing drum is connected to a feeding mechanism.

[0007] This utility model discloses a high-efficiency aluminum powder mixer for the purpose of preparing aluminum slurry. The mixing chamber of the material bucket serves as the mixing zone, and the mixing components on the mixing drum are used to perform mixing operations within this mixing zone to fully mix aluminum powder with a fluid such as water. When mixing is required, the mixing drum descends from the open end of the material bucket and enters, closing the open end as it reaches the desired position to effectively prevent dust from spilling out during the mixing process and protect the working environment. The feeding mechanism is used to specifically input aluminum powder, water, or other appropriate materials.

[0008] In the aforementioned high-efficiency aluminum powder mixer, the mixing drum includes a cylinder with an open lower end, and the mixing assembly is provided at the top of the cylinder. The outer diameter of the cylinder is adapted to the inner diameter of the material bucket.

[0009] The main body of the mixing drum is an inverted cylinder that can be inserted into the material bucket. The mixing is driven by the mixing components inside the drum, which can more effectively prevent dust from overflowing.

[0010] In the above-mentioned high-efficiency aluminum powder mixer, the mixing assembly includes at least one mixing shaft rotatably connected to the top surface of the cylinder, and at least one layer of mixing turbines are axially arranged on the mixing shaft, or the mixing shaft is provided with a spiral mixing part, and the mixing shaft is connected to a first circumferential drive.

[0011] Multiple sets of stirring components can be set to improve stirring efficiency and uniformity. Specifically, stirring can be achieved through stirring turbines or spiral stirring parts. Multiple sets of stirring turbines are arranged axially on the stirring shaft to ensure comprehensive stirring in the axial direction, while spiral stirring parts are wound around the stirring shaft in a spiral shape.

[0012] In the above-mentioned high-efficiency aluminum powder mixer, the upper end of the stirring shaft penetrates through the top surface of the cylinder and protrudes, and the first circumferential drive is connected to the upper end of the stirring shaft; the stirring turbines of each stirring shaft are staggered in the height direction.

[0013] The first cycle drives the output end of the driver to the upper end of the stirring shaft to provide stirring driving force. The stirring turbine parts on the adjacent stirring shafts extend into the space between two axially adjacent stirring turbines, forming an interlaced arrangement, which helps to improve stirring efficiency.

[0014] In the aforementioned high-efficiency aluminum powder mixer, the feeding mechanism includes a storage tank for storing aluminum powder. The upper end of the storage tank is connected to a feeding pipe. The discharge end of the feeding pipe is connected to the top of the mixing drum and communicates with the mixing chamber. A negative pressure feeding component is connected to the feeding pipe. A fluid input pipe for inputting the mixed fluid is also connected to the mixing drum.

[0015] The feeding mechanism draws aluminum powder from the storage tank into the mixing chamber through the feeding pipe, while the fluid input pipe introduces a mixed fluid, such as water, into the mixing chamber. The aluminum powder and water are exposed to the shear surface of the mixing components in the mixing chamber, ensuring the mixing effect.

[0016] In the aforementioned high-efficiency aluminum powder mixer, radially extending rotating shafts are fixed on both sides of the material hopper. The rotating shafts are rotatably connected to the frame and are connected to a second circumferential drive.

[0017] The material hopper is mounted on the frame via a rotating shaft, allowing it to rotate in the vertical plane to achieve the effect of pouring out the mixed product after mixing, facilitating the output of the finished product. This rotation is driven by the second cycle to the driver.

[0018] In the aforementioned high-efficiency aluminum powder mixer, the mixing drum lifting structure includes a connecting plate fixed to the upper end of the mixing drum, the connecting plate being slidably connected to a connecting rod, the connecting rod being fixedly connected to the frame, and the connecting plate being connected to a vertically arranged linear drive assembly.

[0019] The mixing drum is slidably connected to the vertical connecting rod of the frame via a connecting plate, enabling the mixing drum to be raised and lowered. The linear actuator is used to push the connecting plate upward to raise the mixing drum, while the lowering action can be achieved by gravity. The linear drive component can be a pneumatic cylinder, an electric cylinder, or a motor lead screw assembly, which is existing technology and will not be elaborated on further.

[0020] In the above-mentioned high-efficiency aluminum powder mixer, the material bucket and / or the mixing drum are also connected to a cooling system. The cooling system includes heat exchange tubes disposed on the outer wall of the material bucket and / or on the top surface of the mixing drum. The heat exchange tubes are connected to a heat exchange medium flow assembly, and a heat exchange medium flows inside the heat exchange tubes.

[0021] The cooling system is used to control the stirring temperature and improve safety. Specifically, it absorbs heat through heat exchange tubes, and the heat exchange medium circulation component is used to drive the circulation of the heat exchange medium inside the tubes to ensure heat exchange efficiency.

[0022] In the above-mentioned high-efficiency aluminum powder mixer, an airflow control system is also provided between the mixing drum and the material bucket. The airflow control system includes a high-speed airflow generating component, which is connected to the mixing chamber through an air outlet pipe.

[0023] The airflow control system is used to push the product flow to form a flow opposite to the stirring direction, so that the product flow is effectively sheared by the stirring components, thereby improving the stirring efficiency.

[0024] In the above-mentioned high-efficiency aluminum powder mixer, an air inlet nozzle and an air outlet are provided on the top surface of the mixing drum. The air inlet nozzle and the air outlet end of the air outlet pipe are connected. The output direction of the air inlet nozzle is adapted to the circumferential direction of the mixing drum and is opposite to the mixing direction of the mixing component. The air outlet is connected to the mixing chamber and is provided with a dust removal component.

[0025] The high-speed airflow generating component outputs high-speed airflow from the air inlet nozzle through the air outlet pipe. The air inlet nozzle can be similar to an L-shape, and its output direction is tangent to the circumferential direction of the mixing drum, which helps to promote the circumferential flow of the product. The air outlet is designed to balance the internal and external air pressure, and the dust removal component on it can prevent dust from escaping, which helps to protect the working environment.

[0026] Compared with the prior art, the present invention has the following main advantages:

[0027] 1. When mixing is required, the mixing drum descends into the material bucket through the open opening at the top and closes the opening as it reaches the material bucket, effectively preventing dust from spilling out during the mixing process and protecting the working environment.

[0028] 2. The main body of the mixing drum is an inverted cylinder that can be inserted into the material bucket. The mixing is driven by the mixing components inside the drum, which can more effectively prevent dust from overflowing.

[0029] 3. Multiple mixing components can be set to improve mixing efficiency and uniformity.

[0030] 4. The stirring turbine sections on adjacent stirring shafts extend into the space between two axially adjacent stirring turbines, forming an interlaced arrangement, which helps to improve stirring efficiency.

[0031] 5. The feeding mechanism draws aluminum powder from the storage tank into the mixing chamber through the feeding pipe, while the fluid input pipe simultaneously inputs the mixed fluid into the mixing chamber. The aluminum powder and water enter the mixing chamber and are exposed to the shear surface of the mixing components, ensuring the mixing effect.

[0032] 6. The material bucket is mounted on the frame via a rotating shaft, allowing it to rotate in the vertical plane to pour out the mixed product after mixing, facilitating the output of the finished product.

[0033] 7. The cooling system is used to control the stirring temperature and ensure safety.

[0034] 8. The airflow control system is used to push the product flow to form a flow opposite to the stirring direction, so that the product flow is effectively sheared by the stirring components, thereby improving the stirring efficiency. Attached Figure Description

Detailed Implementation

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] Specific implementation examples Figure 1 , 2As shown, this high-efficiency aluminum powder mixer includes a frame 1, on which a material bucket 2 and a mixing drum 3 are provided. The material bucket 2 has an open mixing chamber at the top. The mixing drum 3 is mounted on the frame 1 through a mixing drum lifting structure, which can move downward to allow the mixing component 4 to enter the mixing chamber and close the open opening 21. The mixing drum 3 is connected to the feeding mechanism 5.

[0040] Specifically, this high-efficiency aluminum powder mixer is used to achieve high-efficiency mixing of aluminum powder to prepare aluminum slurry. The mixing chamber of the material tank 2 serves as the mixing generation zone, and the mixing component 4 on the mixing drum 3 is used to perform mixing operations within this mixing generation zone to fully mix aluminum powder and water. When mixing is required, the mixing drum 3 descends from the open port 21 at the top of the material tank 2 and enters, closing the open port 21 as it reaches the position, effectively preventing dust from overflowing during the mixing process and protecting the working environment.

[0041] like Figure 2 As shown, the mixing drum 3 includes a cylinder 31 with an open lower end, and a mixing assembly 4 is provided on the top of the cylinder 31. The outer diameter of the cylinder 31 is adapted to the inner diameter of the material tank 2. The mixing assembly 4 includes two mixing shafts 41 rotatably connected to the inner top surface of the cylinder 31. Multiple layers of mixing turbines 42 are axially arranged on the mixing shafts 41. The upper end of the mixing shafts 41 penetrates the top surface of the cylinder 31 and is drivenly connected to the first circumferential drive. The two sets of mixing turbines 42 are staggered in the height direction.

[0042] Specifically, the main body of the mixing drum 3 is an inverted cylinder 31, which can be inserted into the material bucket 2. The mixing is driven by the mixing assembly 4 inside the cylinder 31, which can more effectively prevent dust from overflowing. Multiple sets of mixing assemblies 4 can be provided to improve mixing efficiency and uniformity. Specifically, mixing can be achieved through mixing turbines 42. Multiple sets of mixing turbines 42 are axially arranged on the mixing shaft 41 to ensure comprehensive mixing in the axial direction. The output end of the first circumferential driver is connected to the upper end of the mixing shaft 41 to provide mixing driving force. Parts of the mixing turbines 42 on adjacent mixing shafts 41 extend into the space between two axially adjacent mixing turbines 42, forming an interlaced arrangement, which helps to improve mixing efficiency.

[0043] like Figure 1 As shown, the feeding mechanism 5 includes a storage tank 51 for storing aluminum powder. The upper end of the storage tank 51 is connected to a feeding pipe 52. The discharge end of the feeding pipe 52 is connected to the top of the mixing drum 3 and communicates with the mixing chamber. A negative pressure feeding component is connected to the feeding pipe 52. A fluid input pipe for inputting water is also connected to the mixing drum 3.

[0044] Specifically, the feeding mechanism 5 draws aluminum powder from the storage tank 51 into the mixing chamber through the feeding pipe 52, while the fluid input pipe inputs water into the mixing chamber. Moreover, the output end of the fluid input pipe is equipped with a dispersive nozzle, which can output water in the form of a fan. The fan extends radially, and the aluminum powder collides with the fan of fluid during the flow, resulting in mixing. In addition, the aluminum powder and water are exposed in the shear surface of the mixing component 4 when they enter the mixing chamber, ensuring the mixing effect.

[0045] As an optimization of this embodiment, radially extending rotating shafts 22 are fixed on both sides of the material barrel 2. The rotating shafts 22 are rotatably connected to the frame 1 and are connected to the second circumferential drive.

[0046] Specifically, the material bucket 2 is mounted on the frame 1 via a rotating shaft 22, and can rotate in the vertical plane to achieve the effect of pouring out the mixed product after mixing, which facilitates the output of the product. This rotation provides driving force to the driver through the second rotation.

[0047] In this embodiment, the stirring drum lifting structure includes a connecting plate 32 fixed to the upper end of the stirring drum 3. The connecting plate 32 is slidably connected to the connecting rod 11. The connecting rod 11 is fixedly connected to the frame 1. The connecting plate 32 is connected to a vertically arranged cylinder.

[0048] Specifically, the mixing drum 3 is slidably connected to the vertical connecting rod 11 of the frame 1 via the connecting plate 32, thereby realizing the lifting function of the mixing drum 3. The linear drive is used to push the connecting plate 32 upward to realize the upward movement of the mixing drum 3, and the downward movement can be realized by gravity.

[0049] As an optimization, the frame 1 is also equipped with a cooling system 6. The cooling system 6 includes a heat exchange tube 61 installed on the outer wall of the material barrel 2 and on the top surface of the mixing drum 3. The heat exchange tube 61 is connected to the heat exchange medium flow assembly 62, and a heat exchange medium flows inside the heat exchange tube 61.

[0050] Specifically, the cooling system 6 is used to control the stirring temperature and improve safety. It can absorb heat through the heat exchange tube 61, and the heat exchange medium circulation component 62 is used to drive the circulation of the heat exchange medium in the tube to ensure heat exchange efficiency.

[0051] As an optimization, an airflow control system 7 is also provided between the mixing drum 3 and the material bucket 2. The airflow control system 7 includes a high-speed airflow generating component 71, which is connected to the mixing chamber through an air outlet pipe 72. An air inlet nozzle 73 and an air outlet 74 are provided on the inner top surface of the mixing drum 3. The air inlet nozzle 73 is connected to the air outlet end of the air outlet pipe 72. The output direction of the air inlet nozzle 73 is adapted to the circumferential direction of the mixing drum 3 and is opposite to the mixing direction of the mixing component 4. The air outlet 74 is connected to the mixing chamber and is equipped with a dust removal component.

[0052] Specifically, the airflow control system 7 is used to drive the product flow to form a flow opposite to the stirring direction, so that the product flow is effectively sheared by the stirring component 4, thereby improving the stirring efficiency. The high-speed airflow generating component 71 outputs high-speed airflow from the air inlet nozzle 73 through the air outlet pipe 72. The air inlet nozzle 73 is similar to an L-shape, and its output direction is tangent to the circumferential direction of the stirring cylinder 3, which helps to promote the circumferential flow of the product flow. The setting of the air outlet 74 can balance the internal and external air pressure, and the dust removal component on it can prevent dust from escaping, which is beneficial to protecting the working environment.

[0053] Specific working principle: When stirring is required, the stirring drum 3 descends into the stirring chamber, the stirring shaft 41 rotates, and then the feeding pipe 52 draws aluminum powder from the storage tank 51 into the stirring chamber. Simultaneously, the fluid input pipe feeds water in a fan shape. The aluminum powder and water are sheared and mixed by the blades of the stirring turbine 42. At the same time, the air inlet nozzle 73 outputs a high-speed airflow, and the unmixed aluminum powder flows against the stirring direction in the stirring chamber to ensure thorough mixing with the water. After mixing is completed, the stirring drum 3 rises and leaves the stirring chamber, and the material tank 2 rotates to pour out the aluminum slurry. During the stirring process, the heat exchange medium circulates in the heat exchange tube 61, absorbing heat.
