Description

Technical Field

[0001] The utility model relates to the technical field of copper powder atomization devices, in particular to a flow-adjustable copper powder atomization device. Background Art

[0002] The copper powder atomization device is a key equipment for preparing copper powder. It mainly converts copper solution into copper powder through specific atomization technology.

[0003] The patent application document with publication number CN210412538U discloses an atomization device for preparing copper powder. The device sprays a copper solution into the interior of an atomization shell through a spray hole at the bottom of a leaky crucible. During the process of the copper solution entering the interior of the atomization shell, a high-pressure water flow is synchronously sprayed through a nozzle seat to quickly crush the copper melt to form copper powder. The copper powder falls into a cooling medium circulating inside the atomization shell to obtain an atomized material.

[0004] Although the device can achieve copper powder atomization, we noticed a key phenomenon during the actual operation: the size of the inner diameter of the nozzle has a significant impact on the flow rate of the copper solution. When all other factors, such as the parameters of the high-pressure water flow, the design of the atomization equipment and the operating conditions, are kept constant, there is a direct correlation between the inner diameter of the nozzle and the flow rate of the copper solution. Specifically, the larger the inner diameter of the nozzle, the greater the flow rate of the copper solution sprayed out. Conversely, the smaller the inner diameter of the nozzle, the smaller the flow rate of the copper solution sprayed out.

[0005] When the flow rate of the copper solution needs to be adjusted according to production needs, the device has a significant problem, that is, the leaky crucible and the nozzle are integrally formed, which means that when the flow rate of the copper solution needs to be adjusted, we must replace the leaky crucible that matches the required flow rate. Because it is necessary to prepare leaky crucibles of various specifications to cope with different production needs, the production cost increases, and the frequent replacement and disassembly of the leaky crucible also increases the workload and reduces the overall work efficiency.

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0031] A flow-adjustable copper powder atomization device according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 6 As shown, a flow-adjustable copper powder atomizing device according to an embodiment of the utility model comprises an atomizing housing 1, a nozzle seat 2, An adjusting component 3 and a leaking crucible 4, wherein the nozzle seat 2 is fixedly connected to the top of the atomizing shell 1, a conical groove 21 is provided on the top of the nozzle seat 2, and the conical groove 21 is communicated with the inside of the atomizing shell 1; the adjusting component 3 comprises a support 31, a screw adjustment mechanism 32, three groups of mesh seats 33 and a pointer mechanism 34, wherein the support 31 is bolted to the top of the nozzle seat 2, and one end of the support 31 is communicated with the inside of the conical groove 21; the screw adjustment mechanism 32 is arranged on the top of the support 31, and one end of the screw adjustment mechanism 32 is communicated with the inside of the support 31; the three groups of mesh seats 33 are respectively arranged on the top of the screw adjustment mechanism 32, and correspond to the position of the conical groove 21, and one group of mesh seats 33 is communicated with the inside of the screw adjustment mechanism 32; the pointer mechanism 34 is arranged on the surface of the screw adjustment mechanism 32; the leaking crucible 4 is bolted to the top of the screw adjustment mechanism 32, and the bottom of the leaking crucible 4 is located on the outside of the mesh seat 33 corresponding to the position of the conical groove 21, and is communicated with the inside of the mesh seat 33.

[0033] It should be noted that the atomizing housing 1 , the nozzle holder 2 and the leaking crucible 4 described in this embodiment are all prior arts, and therefore will not be described in detail. A cooling medium circulates inside the atomizing housing 1 .

[0034] It should also be noted that the larger the inner diameter of the spray hole, the larger the volume of the copper solution sprayed, and the smaller the inner diameter of the spray hole, the smaller the volume of the copper solution sprayed. The smaller the volume of the copper solution, the easier it is to break up, and the smaller the particle size after breaking up, which is more convenient for subsequent suction filtration and drying. Therefore, the mesh 334 in the mesh seat 33 of the device are all set to be smaller than the inner diameter of the spray hole, and the inner diameter of the spray hole corresponds to the maximum flow rate.

[0035] Specifically, the copper melt is poured into the leaking crucible 4, and the copper melt is sprayed downward through the spray hole. While the copper melt is sprayed, the nozzle holder 2 simultaneously ejects water and quickly crushes the copper melt to form copper powder. The copper powder falls into the cooling medium circulating inside the atomizing shell 1 to obtain atomized material.

[0036] Since the leaky crucible 4 and the spray hole are integrally formed, the flow rate of the molten copper can only be adjusted by replacing the leaky crucible 4. However, this method requires preparing multiple sets of leaky crucibles 4, which has a high production cost, and the back and forth disassembly and assembly leads to reduced work efficiency. For this reason, the device is provided with an adjustment component 3, which includes a support 31, a screw adjustment mechanism 32, three sets of mesh seats 33 and a pointer mechanism 34. When it is necessary to adjust the flow rate of the molten copper, the three sets of mesh seats 33 are driven to move by the screw adjustment mechanism 32. The inner diameter of the mesh 334 in the three sets of mesh seats 33 is smaller than the inner diameter of the spray hole, and gradually decreases in sequence. By changing the position of the mesh seat 33, the switching purpose is achieved. When the mesh 334 is connected to the spray hole, since the outlet of the mesh 334 is smaller than the inner diameter of the spray hole, the purpose of adjusting the flow rate of the copper solution is achieved. During the adjustment process, the pointer mechanism 34 can be used to observe whether the mesh 334 is aligned with the spray hole, and the use effect is good.

[0037] Furthermore, if Figure 3 As shown, the support 31 includes a frame 311, a groove 312, a fixed slide 313, a mounting hole 314, a conical seat 315, a positioning cylinder 316 and a fixing screw 317, wherein the frame 311 is arranged on the top of the atomizing housing 1; the groove 312 is opened on the top of the frame 311; the fixed slide 313 is fixedly connected to the inner wall of the groove 312; the mounting hole 314 is opened at the center of the top of the fixed slide 313 and corresponds to the position of the conical groove 21; one end of the conical seat 315 is threadedly connected to the inner wall of the mounting hole 314 The other end of the conical seat 315 penetrates into the interior of the conical groove 21 and is connected with the interior of the conical groove 21. The end of the conical seat 315 that penetrates into the interior of the conical groove 21 is adapted to the internal dimensions of the conical groove 21. The positioning cylinder 316 is fixedly connected around the bottom of the frame 311 and is slidably connected to the inner wall of the positioning hole on the surface of the nozzle seat 2. The fixing screw 317 is threadedly connected to the inner wall of the positioning cylinder 316. One end of the fixing screw 317 penetrates out of the bottom of the positioning cylinder 316 and is screwed and fixed to the threaded hole on the top of the atomizing shell 1.

[0038] Specifically, align the positioning cylinder 316 with the positioning hole on the surface of the nozzle seat 2, align the conical seat 315 with the conical groove 21, and then press down the frame 311. The frame 311 descends to drive the conical seat 315 to enter the conical groove 21. The frame 311 descends to drive the positioning cylinder 316 to abut against the top of the atomizer shell 1. Then, the fixing screw 317 is rotated by a tool. The fixing screw 317 rotates down and is screwed and fixed to the threaded hole on the top of the atomizer shell 1, thereby fixing the support 31. The nozzle seat 2 and the support 31 share the fixing screw 317 to be fixed to the top of the atomizer shell 1, which reduces the hole opening operation and has a good use effect.

[0039] Furthermore, if Figure 4As shown, the screw adjustment mechanism 32 includes a threaded screw 321, a guide rod 322, an adjustment handle 323 and a switching slide 324, wherein the threaded screw 321 is rotatably connected to the inner wall of the groove 312 and is located on one side of the fixed slide 313; the guide rod 322 is fixedly connected to the inner wall of the groove 312 and is located on the other side of the fixed slide 313; one end of the threaded screw 321 passes through the outside of the frame 311 and is fixedly connected to the adjustment handle 323; the switching slide 324 is slidably connected to the top of the fixed slide 313, one end of the switching slide 324 is threadedly connected to the outer surface of the threaded screw 321, and the other end of the switching slide 324 is slidably connected to the outer surface of the guide rod 322; three groups of positioning and mounting grooves 325 are opened on the top of the switching slide 324, and the three groups of positioning and mounting grooves 325 correspond to the positions of the tapered groove 21 respectively, and one group of positioning and mounting grooves 325 is connected to the inside of the tapered seat 315.

[0040] It should be noted that the switching slide 324 described in this embodiment is adapted to the outer dimensions of the groove 312 .

[0041] Specifically, turning the adjustment handle 323 can synchronously drive the threaded screw 321 to rotate, and the rotation of the threaded screw 321 synchronously drives the switching slide 324 to move to one side along the surface of the threaded screw 321, the surface of the guide rod 322 and the surface of the fixed slide 313. The movement of the switching slide 324 synchronously drives the positioning mounting groove 325 and the mesh seat 33 to move, and the other set of positioning mounting grooves 325 and the mesh seat 33 are moved to the position of the conical seat 315 and connected with the conical seat 315 to realize the switching operation.

[0042] Furthermore, if Figure 5 As shown, the mesh seat 33 includes a seat body 331, a threaded portion 332, a perforated plate 333 and a mesh 334, wherein the threaded portion 332 is integrally formed and arranged at the bottom of the seat body 331, and is threadedly connected to the inner wall of the positioning and mounting groove 325, one end of the threaded portion 332 is connected to the interior of the positioning and mounting groove 325, and the other end of the threaded portion 332 is connected to the interior of the seat body 331; the seat body 331 is located in the interior of the positioning and mounting groove 325, and the top of the seat body 331 is in the same plane as the top of the fixed slide 313 and the top of the frame 311; the perforated plate 333 is integrally formed and arranged at the bottom of the seat body 331, and is threadedly connected to the inner wall of the positioning and mounting groove 325, and one end of the threaded portion 332 is connected to the interior of the seat body 331; The mesh holes 334 are evenly arranged on the surface of the orifice plate 333; the number of mesh holes 334 on the three groups of orifice plates 333 is equal to the number of the spray holes at the bottom of the leaky crucible 4, and the positions are corresponding. The inner diameters of the mesh holes 334 on the three groups of orifice plates 333 are all smaller than the inner diameter of the spray holes at the bottom of the leaky crucible 4. The inner diameters of the mesh holes 334 on the three groups of orifice plates 333 gradually decrease along the Y-axis direction. The cross-section of the mesh holes 334 is conical. The inner diameter of the feed port of the mesh holes 334 is consistent with the inner diameter of the spray hole and is connected. The inner diameter of the discharge port of the mesh holes 334 is smaller than the inner diameter of the spray hole.

[0043] It should be noted that the threaded portion 332 described in this embodiment is designed to be easy to disassemble and assemble, the top of the seat body 331, the top of the fixed slide 313 and the top of the frame 311 are all in the same plane, which is convenient for the movement of the fixed slide 313, and during the movement of the fixed slide 313, there will be no conflict with the leaking crucible 4, and the conical shape of the mesh 334 is designed to facilitate smooth transportation and discharge of materials, and the use effect is good.

[0044] It can be extended that if one does not want to disassemble and assemble the adjustment component 3, the middle group of mesh seats 33 can be manufactured into a mesh seat 33 without a perforated plate 333, so that the normal use of the spray hole will not be affected during use. The specific situation can be adjusted according to actual needs.

[0045] It can also be understood that the number of the nozzle holes is 18 or 24, so the number of the mesh holes 334 is also 18 or 24.

[0046] Specifically, the inner diameters of the mesh holes 334 on the three groups of orifice plates 333 are set to be smaller than the inner diameter of the nozzle hole. However, when the flow rate needs to be adjusted, the mesh holes 334 are moved to the nozzle hole position and connected to the nozzle hole. Since the outlet of the mesh holes 334 is smaller than the inner diameter of the nozzle hole, the purpose of adjusting the flow rate of the molten copper is achieved.

[0047] Furthermore, if Figure 6 As shown, the pointer mechanism 34 includes three groups of pointers 341 and positioning blocks 342, wherein the three groups of pointers 341 are respectively fixedly connected to the top of the fixed slide 313 and slidably connected to the top of the frame 311; the three groups of pointers 341 correspond to the center positions of the three groups of positioning mounting grooves 325 respectively; the positioning block 342 is fixedly connected to the top of the frame 311 and is located on the outside of the pointer 341, and the positioning block 342 corresponds to the center position of the conical groove 21.

[0048] It should be noted that when the positions of the pointer 341 and the positioning block 342 described in this embodiment correspond to each other, it means that the positions of the mesh 334 and the nozzle hole correspond to each other, and their centers are on the same axis.

[0049] Specifically, the movement of the fixed slide 313 synchronously drives the mesh seat 33 and the pointer 341 to move. When the pointer 341 is aligned with the positioning block 342, it means that the mesh seat 33 is currently installed in place. The operation is simple, the observation is convenient, and the use effect is good.

[0050] Furthermore, if Figure 3 As shown, a sealing gasket 100 is arranged between the bottom of the frame 311 and the top of the nozzle seat 2 , and a through hole is opened on the surface of the sealing gasket 100 to facilitate one end of the conical seat 315 to penetrate into the conical groove 21 .

[0051] It should be noted that the sealing gasket 100 described in this embodiment is used to improve the sealing performance of the connection, and the through-hole design facilitates the conical seat 315 to pass through, so the use effect is good.

[0052] In summary, the utility model embodiment is a flow-adjustable copper powder atomization device. The device adjusts the inner diameter of the spray hole at the bottom of the leaky crucible 4 by adjusting the component 3, so as to achieve the purpose of flow regulation, so that it can adapt to different production needs. There is no need to adjust the inner diameter of the spray hole by replacing the leaky crucible 4, thereby reducing production costs. At the same time, the labor intensity is reduced by reducing the number of replacements, and the work efficiency is improved.
