Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting equipment, in particular to a powder feeding device for metal smelting. Background Art

[0002] A common method of metal smelting is to use reducing agents such as carbon, carbon monoxide, and hydrogen to react with metal oxides at high temperatures to obtain metal elements. This is a process that changes metals from a combined state to a free state.

[0003] The existing patent with publication number CN218120603U proposes a powder delivery device for metal smelting, which is provided with a bottom plate, a bracket is fixedly connected to the center of the top of the bottom plate, a turntable is provided on the top of the bottom plate, a connecting rod is fixedly connected to one side of the top of the turntable, a pushing component is provided on one side of the turntable, and a medicine placing component is provided on one side of the pushing component. The powder delivery device for metal smelting, by providing the pushing component, realizes that during the use of the powder delivery device for metal smelting, the medicine powder is placed inside the placement tube, the turntable is rotated, and the placement tube is moved to the top of the furnace. When the placement tube moves to the middle of the furnace, the position of the turntable is fixed, and the push rod is pulled to the side away from the furnace.

[0004] Although the above-mentioned feeding device reduces powder waste by moving the pressure ring upward through the powder feeding assembly to make it more fully reacted, it does not have the function of quantitatively controlling the metal powder when feeding. The existing direct manual addition is often easy to cause incomplete powder reaction inside the furnace box, causing blockage and other problems, affecting the processing of metal powder smelting and reducing the processing efficiency. In view of the above problems, we propose an improved and upgraded powder feeding device for metal smelting. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes, and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 - Figure 4As shown in the figure, the present embodiment provides a powder feeding device for metal smelting, including a furnace box 1. A lifting component 2 is fixedly arranged on the outer wall of the furnace box 1. A placement rack 3 is arranged on one side of the lifting component 2, and a powder storage box 4 is arranged on the upper end surface of the placement rack 3. A small blower 8 is fixedly arranged on the upper end surface of the powder storage box 4, and a telescopic hose 5 is arranged at the output end of the small blower 8. One end of the telescopic hose 5 is fixedly provided with a connection port 9, and the connection port 9 is installed inside the feeding box 6. A control component 7 is fixedly arranged at the lower end of the feeding box 6.

[0025] Preferably, the lifting component 2 includes a first motor 22, a threaded rod 23 and a fixed frame 21. The first motor 22 is fixedly arranged inside the fixed frame 21, and the output end of the first motor 22 is connected with the threaded rod 23. A moving seat 24 is threadedly connected to the outer wall of the threaded rod 23. Sliders 25 are arranged on the front and rear sides of the outer wall of the moving seat 24. A chute 28 is opened inside the fixed frame 21, and the sliders 25 are slidably connected to the chute 28. A limiting groove 29 is opened on the outer wall of the fixed frame 21. A limiting plate 26 is fixedly connected to the outer wall of the moving seat 24, and the placement rack 3 is fixedly installed on the outer wall of the limiting plate 26. A limiting block 27 is fixedly arranged on the inner wall of the limiting plate 26, and the limiting block 27 is slidably connected to the outer wall of the limiting groove 29.

[0026] By driving the first motor 22 inside the fixed frame 21 to drive the moving seat 24 on the outer wall of the threaded rod 23 to move, the moving seat 24 uses the sliders 25 to move and be limited inside the chute 28, so that the moving seat 24 drives the placement rack 3 fixed by the limiting plate 26 to lift stably. At the same time, when the limiting plate 26 is lifting, the limiting block 27 slides and supports inside the limiting groove 29 to improve the stability of the lifting of the placement rack 3.

[0027] Preferably, the control component 7 includes a second motor 73, a rotating cylinder 76 and a feeding pipe 71. The output end of the second motor 73 is connected with the rotating cylinder 76, and one end of the rotating cylinder 76 is fixedly connected to the bottom of the rotating disk 74. The outer wall of the rotating cylinder 76 is rotatably installed in the middle of the positioning plate 75. Guide grooves 77 are opened inside both the rotating disk 74 and the positioning plate 75, and the sizes of the two guide grooves 77 are adapted to each other. The second motor 73 is fixedly arranged on the support plate 72, and six fixing rods 78 are fixedly arranged on the outer wall of the support plate 72, and the fixing rods 78 are installed inside the feeding pipe 71.

[0028] By driving the second motor 73 inside the feeding pipe 71 to work, the second motor 73 drives the rotating disk 74 at one end of the rotating cylinder 76 to rotate. The positioning plate 75 is supported and fixed by the positioning rods on the support plate 72. When the guide groove 77 inside the rotating disk 74 is aligned with the guide groove 77 inside the positioning plate 75 during rotation, the metal powder falls from the guide groove 77 into the lower furnace box 1 for processing and smelting.

[0029] The working principle and process of the present utility model are as follows: First, connect the external power supply. Drive the first motor 22 inside the driving fixing frame 21 to drive the moving seat 24 on the outer wall of the threaded rod 23 to move, so that the moving seat 24 uses the slider 25 to move and be limited inside the chute 28. Thus, the moving seat 24 drives the placing rack 3 fixed by the limiting plate 26 to lift stably. At the same time, when the limiting plate 26 is lifting, it uses the limiting block 27 to slide and support inside the limiting groove 29 to improve the stability of the lifting of the placing rack 3. When the powder storage box 4 on the placing rack 3 is lifted to an appropriate distance, the staff connects the connection port 9 at one end of the telescopic hose 5 with the outer wall of the feeding box 6. At this time, drive the small blower 8 to put the metal powder into the inside of the blanking pipe 71. By driving the second motor 73 inside the blanking pipe 71 to work, the second motor 73 drives the rotating disk 74 at one end of the rotating cylinder 76 to rotate. The positioning plate 75 is supported and fixed by the positioning rod on the supporting plate 72. When the internal guiding groove 77 of the rotating disk 74 is aligned with the internal guiding groove 77 of the positioning plate 75 during rotation, the metal powder falls from the guiding groove 77 to the lower melting furnace box 1 for processing and smelting. The blanking of the metal powder can be controlled to avoid problems such as incomplete powder smelting caused by excessive dropping.
