Description

Technical Field

[0001] This utility model relates to the field of boron powder mixing technology, and in particular to a high-efficiency stirring and mixing device for boron powder. Background Technology

[0002] In modern industry, boron powder, with its excellent properties of high hardness and low density, has shown great application potential in many sectors, such as aerospace, electronics, and new energy. However, boron powder faces several challenging problems when mixed with additives. Due to the high surface energy of boron powder particles, electrostatic forces are significant, making the particles easily attract each other and agglomerate. Traditional stirring methods often fail to provide sufficient dispersing force to effectively disperse the agglomerated boron powder particles. Moreover, uniaxial stirring has obvious limitations; during stirring, boron powder tends to adhere to the walls of the mixing tank and deposit at the bottom. This not only leads to uneven mixing, reducing product quality and performance, but also may waste raw materials and increase production costs. To address these issues, we propose a high-efficiency boron powder stirring and mixing device. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency boron powder stirring and mixing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-efficiency boron powder mixing device includes a mixing tank, a stirring device connected to the upper middle part of the mixing tank, a spray tank connected to one side of the upper end of the mixing tank, a conical conveying hood connected to the lower end of the spray tank, the lower end of the conical conveying hood extending into the mixing tank, four spray pipes evenly spaced around the circumference of the spray tank, the upper ends of the spray pipes connected to conveying pipelines, a support frame fixed to one side of the mixing tank, a rare earth atomizing liquid storage tank mounted on the support frame, a conveying device connected to one side of the rare earth atomizing liquid storage tank, the conveying device connected to the conveying pipeline, a conveying pipe connected to the upper end of the spray tank, and an output pipe connected to the bottom of the mixing tank.

[0006] Preferably, the stirring device includes a drive motor fixed at the middle of the upper end of the mixing tank, and a stirring rod is connected to the end of the output shaft of the drive motor. Multiple rectangular stirring blades and spiral stirring blades are fixed at equal intervals around the stirring rod.

[0007] Preferably, the delivery pipeline includes a fixed pipe connected to the upper end of the nozzle, and four fixed pipes are connected by a joint.

[0008] Preferably, the conveying device includes a conveying pump connected to one side of the rare earth atomizing liquid storage tank, one end of the conveying pump is connected to a connecting pipe, and one end of the connecting pipe is connected to the upper end of the connector.

[0009] Preferably, multiple sensor groups are evenly spaced on one side of the mixing tank.

[0010] Preferably, a plurality of nozzles are connected at equal intervals on one side of the spray pipe, and the nozzles penetrate the side wall of the spray tank and extend into the spray tank.

[0011] In this utility model, during processing:

[0012] 1. Premixing stage

[0013] Boron powder, along with additives and nitrogen, enters the spray tank through the feed inlet of the conveying pipe. At this time, the conveying equipment starts to work. The conveying pump extracts the rare earth atomizing liquid from the rare earth atomizing liquid storage tank, conveys it to the connector through the connecting pipe, and then distributes it to each spray pipe through the fixed pipe. Finally, it is sprayed out from the nozzle in the form of atomization. In the spray tank, the raw materials and the rare earth atomizing liquid film are in full contact to achieve preliminary premixing. The atomization of CeCl3 solution causes an activation layer to form on the surface of the boron powder, reducing the electrostatic adsorption force.

[0014] 2. Stirring stage

[0015] The premixed modified powder enters the mixing zone of the mixing tank. The drive motor starts, which drives the stirring rod to rotate. The rectangular stirring blades and the spiral stirring blades on the stirring rod rotate accordingly. The rectangular stirring blades generate a strong radial stirring force during rotation, which disperses the material in all directions. The spiral stirring blades generate an axial stirring force, which makes the material circulate up and down in the mixing tank. The multi-directional stirring method can effectively break the agglomeration of boron powder particles, enhance the surface coating effect of boron powder, additives and rare earth atomized liquid, and make the mixing more uniform.

[0016] 3. Monitoring and Output Stage

[0017] During the mixing process, a sensor group installed on one side of the mixing tank monitors parameters such as temperature, pressure, and concentration in real time to ensure that the mixing process is carried out in a stable environment. When the mixing reaches the predetermined requirements, the mixed material is output through the output pipe at the bottom of the mixing tank.

[0018] This utility model has the following advantages:

[0019] 1. This device effectively solves the problems of boron powder particle agglomeration, barrel wall adhesion, and bottom deposition through pre-mixing in the spray tank and multi-directional stirring in the mixing tank, so as to fully mix boron powder with additives and rare earth atomizing liquid, greatly improving the uniformity of mixing, thereby improving the quality and performance of the product.

[0020] 2. During the mixing process, the rare earth atomizing liquid and boron powder come into full contact. The stirring equipment further enhances the surface coating effect, reduces electrostatic adsorption, and enables the additives and rare earth atomizing liquid to better adhere to the surface of the boron powder particles, thereby improving the stability and functionality of the boron powder.

[0021] 3. Because the mixing is more uniform, the waste of raw materials is reduced and the utilization rate of raw materials is improved, thereby reducing production costs. At the same time, the device can improve production efficiency, shorten the production cycle, and further reduce the labor and material costs in the production process.

[0022] In summary, this invention effectively solves the problems of boron powder particle agglomeration, adhesion to the barrel wall, and bottom deposition, ensuring thorough mixing of boron powder with additives and rare earth atomizing liquid. This significantly improves the uniformity of mixing, thereby enhancing product quality and performance. Simultaneously, the stirring equipment further strengthens the surface coating effect, reduces electrostatic adsorption, and allows additives and rare earth atomizing liquid to better adhere to the surface of the boron powder particles, improving the stability and functionality of the boron powder, reducing raw material waste, and increasing raw material utilization.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-5A high-efficiency boron powder mixing device includes a mixing tank 6, a mixing device connected to the middle of the upper end of the mixing tank 6, a spray tank 8 connected to one side of the upper end of the mixing tank 6, and a conical conveying hood 16 connected to the lower end of the spray tank 8. The design of the conical conveying hood 16 can effectively guide the pre-treated material smoothly into the mixing tank 6, reduce the loss of material during the conveying process, and its conical structure helps the material to fall in a concentrated manner, thereby improving the efficiency of entering the mixing tank 6.

[0031] The lower end of the conical conveying hood 16 extends into the mixing tank 6. Four spray pipes 3 are connected at equal intervals around the spray tank 8. The upper end of the spray pipes 3 is connected to the conveying pipeline. A support frame 14 is fixed on one side of the mixing tank 6. A rare earth atomizing liquid storage tank 10 is installed on the support frame 14. A conveying device is connected to one side of the rare earth atomizing liquid storage tank 10. The conveying device is connected to the conveying pipeline. A conveying pipe 1 is connected to the upper end of the spray tank 8. An output pipe 15 is connected to the bottom of the mixing tank 6. Electric valves are installed on both the conveying pipe 1 and the output pipe 15 for remote opening and closing.

[0032] The mixing equipment includes a drive motor 5 fixed at the upper middle part of the mixing tank 6. The output shaft of the drive motor 5 is connected to a stirring rod 18. Multiple rectangular stirring blades 12 and spiral stirring blades 19 are fixed at equal intervals around the stirring rod 18. The rectangular stirring blades 12 and spiral stirring blades 19 are made of high-strength, corrosion-resistant alloy steel, which not only ensures that the stirring blades will not deform during high-speed rotation, but also resists corrosion from materials such as boron powder and additives, extending the service life of the stirring blades. At the same time, the surfaces of the rectangular stirring blades 12 and spiral stirring blades 19 are specially polished to reduce the adhesion of materials on the stirring blades and improve the mixing effect.

[0033] The delivery pipeline includes a fixed pipe 2 connected to the upper end of the nozzle 3, and a joint 7 connected between the four fixed pipes 2 for connecting the delivery. A pressure relief valve and a pressure relief system are connected to the upper side of the mixing tank 6.

[0034] The conveying equipment includes a conveying pump 13 connected to one side of the rare earth atomizing liquid storage tank 10. One end of the conveying pump 13 is connected to a connecting pipe 11, and one end of the connecting pipe 11 is connected to the upper end of the connector 7. The atomization effect of CeCl3 solution directly affects the formation of the boron powder surface activation layer. The atomization degree of CeCl3 solution can be controlled by adjusting the pressure of the conveying pump 13 and the parameters of the nozzle 4, thereby improving the quality of the boron powder surface activation layer.

[0035] Multiple sensor groups 17 are evenly spaced on one side of the mixing tank 6. The sensor groups 17 include various high-precision sensors such as temperature sensors, pressure sensors and concentration sensors. The sensors can monitor various parameters in the mixing tank 6 in real time and accurately. Furthermore, the sensor groups 17 are connected to an external control system. When the monitored parameters exceed the set range, the control system can issue an alarm in time and take corresponding measures to ensure the stability and safety of the mixing process.

[0036] Multiple nozzles 4 are connected at equal intervals on one side of the nozzle 3. The nozzles 4 penetrate the side wall of the spray tank 8 and extend into the spray tank 8. The nozzles 4 can spray the rare earth atomized liquid evenly into the spray tank 8, so that the rare earth atomized liquid can fully contact the material.

[0037] In this utility model, during processing:

[0038] 1. Premixing stage

[0039] Boron powder, along with additives and nitrogen, enters the spray tank 8 through the inlet of the conveying pipe 1. At this time, the conveying equipment starts working, and the conveying pump 13 extracts the rare earth atomizing liquid from the rare earth atomizing liquid storage tank 10, conveys it to the connector 7 through the connecting pipe 11, and then distributes it to each spray pipe 3 through the fixed pipe 2, finally spraying it out from the nozzle 4 in the form of atomization. Inside the spray tank 8, the raw materials and the rare earth atomizing liquid film are in full contact, achieving preliminary premixing. The atomization of the CeCl3 solution forms an activation layer on the surface of the boron powder, reducing electrostatic adsorption.

[0040] 2. Stirring stage

[0041] The premixed modified powder enters the stirring zone of the mixing tank 6. The drive motor 5 starts, driving the stirring rod 18 to rotate. The rectangular stirring blades 12 and the spiral stirring blades 19 on the stirring rod rotate accordingly. The rectangular stirring blades can generate a strong radial stirring force during rotation, dispersing the material in all directions. The spiral stirring blades can generate an axial stirring force, causing the material to circulate up and down in the mixing tank. The multi-directional stirring method can effectively break the agglomeration of boron powder particles, enhance the surface coating effect of boron powder, additives, and rare earth atomized liquid, and make the mixing more uniform.

[0042] 3. Monitoring and Output Stage

[0043] During the mixing process, the sensor group 17 installed on one side of the mixing tank 6 monitors parameters such as temperature, pressure, and concentration in real time to ensure that the mixing process is carried out in a stable environment. When the mixing reaches the predetermined requirements, the mixed material is output through the output pipe 15 at the bottom of the mixing tank.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
