DETAILED DESCRIPTION

[0038] 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.

[0040] Example 1

[0041] Combination Figure 1-Figure 3This embodiment discloses a vacuum atomization furnace, including an atomization barrel 1 and a lower cone 2 connected to the bottom end of the atomization barrel 1. In this embodiment, the atomization barrel 1 is constructed as a cylindrical structure, and the lower cone 2 is constructed as a conical barrel structure. The lower cone 2 is docked and installed at the bottom end of the atomization barrel 1. In actual application, metal powder is atomized in the atomization barrel 1, settles into the lower cone 2, and is collected by the lower cone 2. The bottom end of the lower cone 2 can be connected to a fan absorption mechanism to guide the metal powder out.

[0042] During the long-term collection of metal powder, the inner wall of the lower cone 2 will be contaminated with powder. In order to facilitate the disassembly and cleaning of the lower cone 2, in the present embodiment, the lower cone 2 is detachably connected to the bottom end of the atomizing tube 1. Exemplarily, the connection method can adopt connection structures such as bolt connection, clamping, and cylinder locking.

[0043] Specifically, the bottom end of the atomizing tube 1 is fixedly provided with a first flange 11 along the circumferential direction, and correspondingly, the top end of the lower cone 2 is fixedly provided with a second flange 21 along the circumferential direction that matches the first flange 11. The first flange 11 and the second flange 21 are butt-jointed for connection therebetween.

[0044] Further, the bottom of the first flange 11 is provided with an annular groove 111 along the circumferential direction, and correspondingly, the top of the second flange 21 is provided with an annular protrusion 211 adapted to the annular groove 111 along the circumferential direction. When the first flange 11 and the second flange 21 are docked, the annular protrusion 211 can be inserted into the annular groove 111, thereby ensuring the concentricity of the installation of the atomizer tube 1 and the lower cone 2. Preferably, the insertion end of the annular protrusion 211 is set to a chamfered structure to facilitate the smooth insertion of the annular protrusion 211 into the annular groove 111. It is understandable that in other embodiments, the reverse setting can also be made, that is, the annular protrusion 211 is set at the bottom of the first flange 11, and the annular groove 111 is set at the top of the second flange 21, which does not affect the realization of the centering effect.

[0045] Example 2

[0046] The vacuum atomization furnace disclosed in this embodiment and the vacuum atomization furnace disclosed in Example 1 have substantially the same structure, and for the sake of brevity, only the differences are described in detail herein.

[0047] In this embodiment, the vacuum atomization furnace further includes a reset component 3 for assisting the lower cone 2 to reset. Figure 2 and Figure 3 As shown, the reset assembly 3 includes a reset block 31 fixedly connected to the side end of the second flange 21, and a reset groove block 32 fixedly connected to the side end of the first flange 11, and the reset block 31 and the reset groove block 32 are slidably matched.

[0048] Specifically, Figure 3As shown, the reset block 31 and the second flange 21 have substantially the same thickness. Figure 2 As shown, the reset groove block 32 is constructed as a substantially rectangular block structure with a predetermined height, and is provided with a slide groove along the height direction that matches the shape of the reset block 31. The top side surface of the reset groove block 32 is connected to the side end of the first flange 11, and the bottom extends downward, thereby providing a sliding space for the reset block 31.

[0049] During the disassembly and separation of the lower cone 2, the reset block 31 slides in the reset groove block 32. This arrangement prevents the lower cone 2 from deviating during movement, thereby always ensuring the concentricity of the lower cone 2 and the atomizer tube 1. Similarly, during the upward installation of the lower cone 2, this structure can also ensure the accuracy of its upward movement.

[0050] Example 3

[0051] Based on the vacuum atomization furnace disclosed in the above embodiment, this embodiment discloses an automatic cleaning device for the lower cone of the vacuum atomization furnace, see Figure 1 The automatic cleaning device comprises a lower cone supporting mechanism 4, a running mechanism 5 and a cleaning mechanism 6. The lower cone supporting mechanism 4 is used to support the lower cone 2 and is configured to drive the lower cone 2 to move up and down, thereby separating it from the atomizing tube 1. The running mechanism 5 is used to drive the lower cone supporting mechanism 4 to move between a first position where the atomizing tube 1 is located and a second position where the cleaning mechanism 6 is located. The cleaning mechanism 6 is used to clean the inner wall of the lower cone 2.

[0052] Specifically, the automatic cleaning device includes a mounting platform 7, and a mounting frame group 8 composed of a plurality of vertical support rods 81 and two groups of transverse support rods 82 is fixedly connected to the top of the mounting platform 7. In this embodiment, two groups of transverse support rods 82 are provided, which are constructed as transverse guide rail structures, and the lower cone support mechanism 4 is slidably connected to the transverse support rods 82. The first position and the second position are distributed side by side along the length direction of the transverse support rods 82.

[0053] Combination Figure 4 The lower cone support mechanism 4 includes a gantry 41 in a rectangular frame structure, and the gantry 41 can be formed by welding steel sections. The four corners of the gantry 41 are respectively connected with pulleys 42 that are compatible with the transverse support rod 82, and the pulleys 42 are used to slide and connect the gantry 41 to the transverse support rod 82. The lower cone support mechanism 4 further includes four groups of first linear drive members 43 that are respectively fixedly connected to the top surfaces of the four sides of the gantry 41. The first linear drive members 43 are vertically arranged. Corresponding to this structure, the outer wall of the lower cone 2 is fixedly provided with a connecting edge 22 that matches the first linear drive member 43 along the circumferential direction. The connecting edge 22 is horizontally arranged, and the output end of the first linear drive member 43 is connected to the connecting edge 22.

[0054] In actual application, the atomizer tube 1 is fixedly arranged by a fixed structure. When the staff removes the connection structure between the lower cone 2 and the atomizer tube 1, the first linear drive member 43 is started and drives the lower cone 2 downward to separate from the atomizer tube 1. The first linear drive member 43 can adopt a linear drive structure such as a cylinder, a hydraulic cylinder or an electric push rod. In this embodiment, the first linear drive member 43 is preferably a cylinder with a simple structure and lower transmission cost. The piston rod end of the cylinder is fixedly connected with a push plate 44, and is connected to the connection edge 22 of the lower cone 2 through the push plate 44. The two are preferably bolted to facilitate disassembly and maintenance.

[0055] Continue to see Figure 4 The walking mechanism 5 is used to drive the lower cone support mechanism 4 to move on the transverse guide rail, which includes a second linear drive member 51 fixedly connected to the side end of the transverse support rod 82, and the output end of the second linear drive member 51 is connected to the gantry 41. Specifically, the output end of the second linear drive member 51 is fixedly connected to the top plate 52, and the top plate 52 is fixedly connected to the side end of the gantry 41, and then the gantry 41 is driven by the second linear drive member 51 to perform linear motion along the transverse support rod 82. Preferably, the second linear drive member 51 is set to two groups, which act on the two ends of the gantry 41 respectively to ensure its smooth movement. In this embodiment, the second linear drive member 51 is preferably a driving cylinder with a simple structure and stronger load capacity. The two ends of the driving cylinder are respectively fixedly connected to the side ends of the transverse support rod 82 through a fixed seat, and its output rod is fixedly connected to the top plate 52.

[0056] In this embodiment, the lower cone 2 is fixedly connected to the first linear drive member 43 through the connecting edge 22, and the first linear drive member 43 is fixedly connected to the gantry 41, so that the lower cone 2 and the gantry 41 are connected as a whole, and the rectangular gantry 41 is framed on the lower cone 2, so that it is not easy to tilt, thereby ensuring its vertical stability; the side end of the gantry 41 is connected to the output end of the second linear drive member 51 through the top plate 52, and the second linear drive member 51 is fixedly connected to the transverse support rod 82 through a fixed seat. Such an arrangement can further ensure the horizontal movement stability of the lower cone 2, and the structural coordination in the vertical and horizontal directions can keep the lower cone 2 balanced at all times to prevent it from tipping over or falling off.

[0057] Combination Figure 1 and Figure 5The cleaning mechanism 6 is arranged on the side of the atomizing tube 1, corresponding to the second position, and includes a spraying assembly 61. In this embodiment, the spraying assembly 61 is configured to be able to perform lifting motion. When it descends, it can extend into the interior of the lower cone 2 to clean and purge it. Specifically, the cleaning mechanism 6 is fixedly connected to the mounting frame 8 through a bracket 62. The cleaning mechanism 6 further includes a mounting plate 63 fixedly connected to the bracket 62 and a third linear drive member 64 connected through the mounting plate 63. The spraying assembly 61 is connected to the output end of the third linear drive member 64.

[0058] For more details, see Figure 6-Figure 8 The purge assembly 61 includes a connecting column 611 and a purge part 612 and a cleaning part 613 with a fixed ring disposed on the connecting column 611. The two parts are spaced apart from each other. The cleaning part 613 is used to spray cleaning water to the inner wall of the lower cone 2, and the purge part 612 is used for high-pressure air blowing. The purge part 612 and the cleaning part 613 have substantially the same structure. The structure is described below by taking the purge part 612 as an example: In this embodiment, the purge part 612 is constructed as a disc-shaped structure with a predetermined thickness, including a disc body 6121, wherein an annular channel 6122 is disposed inside the disc body 6121, and a plurality of branch pipes 6123 are spaced apart and distributed along the circumferential direction at the side end of the disc body 6121, and the branch pipes 6123 are connected to the channel 6122. The top or bottom end of the disc body 6121 is provided with an inlet pipe 6124 connected to the channel 6122.

[0059] In the structure of the purge part 612, the inlet pipe 6124 is used to introduce compressed air, and the outlet end of the branch pipe 6123 is configured as a flat outlet or a hole-shaped outlet suitable for air outlet; in the structure of the cleaning part 613, the inlet pipe 6124 is used to introduce cleaning water, and the outlet end of the branch pipe 6123 is configured as a sprinkler head structure suitable for water spraying. When cleaning the inner wall of the lower cone 2, first wash with water, and then use high-pressure air blowing to achieve a thorough cleaning effect.

[0060] To ensure the stability and accuracy of the lifting motion of the purge assembly, in this embodiment, the third linear drive member 64 is preferably a linear motion module, which is connected to the mounting plate 63 via a mounting seat 65, and the lead screw nut of the linear motion module is fixedly connected with a lifting rod 66, which is connected to the mounting plate 63 via a linear bearing, and the bottom end of the lifting rod 66 is fixedly connected to the connecting column 611 of the purge assembly. Furthermore, the purge assembly can be driven to lift and lower through the third linear drive member 64.

[0061] Preferably, the mounting platform 7 is further provided with a water leakage hole 71 at the position corresponding to the second position, a water storage area is correspondingly provided below the water leakage hole 71, and the mounting platform 7 is further connected with a water outlet pipe connected to the water storage area. The cleaning water can be collected through the water leakage hole 71 and the water storage area. Figure 1As shown, the cleaning mechanism 6 further includes curtains 67 respectively connected to the four sides of the bracket 62, and the curtains 67 are used to block during the cleaning operation to prevent water from splashing to other places and affecting the cleanliness of the site.

[0062] After the cleaning operation is completed, the spray assembly 61 moves upward, the second linear drive 51 starts, and the gantry 41 is driven to drive the lower cone 2 to return to the first position. During the return process, the reset block 31 connected to the lower cone 2 gradually extends into the reset groove block 32 connected to the atomizer tube 1 until it is fully docked. Then the first linear drive 43 is started to drive the lower cone 2 upward to reset, and further with the assistance of the reset assembly 3, the upward movement of the lower cone 2 can be prevented from being offset, thereby completing the precise docking of the lower cone 2 and the atomizer tube 1. The structural setting of the reset assembly 3 of the vacuum atomizer can not only ensure the precise return of the lower cone 2 in the horizontal direction, but also ensure the precise reset of the lower cone 2 in the vertical direction.

[0063] Preferably, in order to allow the reset block 31 to smoothly enter the reset groove block 32 during the return process, in this embodiment, the reset block 31 is constructed as a trapezoidal structure with a narrow entry end and a wide rear end.

[0064] It can be understood that the automatic cleaning device provided in this embodiment also includes a control module, and the above-mentioned action processes are all controlled by the control module. The control module can adopt a PLC control system, which can control multiple mechanisms according to a predetermined program, so that each mechanism can start, stop or perform other actions according to a preset process.
