Description

Technical Field

[0001] This utility model relates to the field of refining furnaces, specifically to a refining furnace capable of multi-stage filtration. Background Technology

[0002] A refining furnace is a key piece of equipment in industrial production used to purify metals or other materials. It melts raw materials by heating them at high temperatures and removes impurities through chemical reactions or physical separation, thereby obtaining products with higher purity.

[0003] Screening the raw materials before dissolving them in the refining furnace is a crucial step. The raw materials may contain various impurities, such as soil, sand, and metal fragments. If these impurities enter the refining furnace along with the raw materials, they will mix into the solution during melting, affecting the purity of the solution and ultimately leading to a decline in the quality of the final product.

[0004] However, most refining furnaces currently on the market lack the function of filtering raw materials. This necessitates the use of specialized screening equipment for pre-treatment of raw materials during production. Only after filtration can the raw materials be fed into the refining furnace for subsequent refining operations. This separate operation not only increases the complexity of the production process but also requires more equipment and manpower, significantly reducing overall operational efficiency. Therefore, it is essential to invent a refining furnace capable of multi-stage filtration to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a refining furnace capable of multi-stage filtration. By using four sets of progressively smaller mesh screens arranged in a stepped manner, the raw materials can be filtered four times from coarse to fine, effectively removing impurities from the raw materials. This ensures the purity of the solution, and the raw materials can be directly fed into the melting pot after filtration, achieving simultaneous feeding and filtration, eliminating the need for separate screening of raw materials, thus improving operational efficiency.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1 - Figure 3 The refining furnace shown includes a furnace body 1, a multi-stage filtration mechanism 4, and a disassembly and assembly mechanism 5. A melting pot 2 is snapped into the inside of the furnace body 1. A lifting ring 3 is fixedly connected to the top of the melting pot 2. The lifting ring 3 is lifted by a lifting device, and the melting pot 2 can be removed from the inside of the furnace body 1 by using the lifting device in conjunction with the lifting ring 3.

[0028] The multi-stage filtration mechanism 4 includes a rotating rod 41, which is rotatably connected to the top of the furnace body 1. A slider 42 is slidably connected to the outer wall of the rotating rod 41. When the worm gear 410 rotates, it drives the rotating rod 41 to rotate synchronously. At this time, the rotating rod 41 drives the slider 42 to rotate synchronously. A sieve plate 43 is fixedly connected to the side wall of the slider 42. When the slider 42 rotates, it drives the sieve plate 43 to rotate in a circle around the rotating rod 41. A collection box 44 is snapped into the bottom of the sieve plate 43. The collection box 44 is a rectangular box-shaped structure with an open top. The impurities filtered out can be collected through the collection box 44. For collection, a fixed block 45 is fixedly connected to the outer wall of the rotating rod 41, and a return spring 46 is fixedly connected to the top of the fixed block 45. The top of the return spring 46 is fixedly connected to the bottom of the slider 42. The slider 42 is elastically connected to the fixed block 45 through the return spring 46. The return spring 46 elastically connects the slider 42 to the fixed block 45, allowing the slider 42 to slide up and down on the outer wall of the rotating rod 41. A vibration motor 47 is fixedly connected to the bottom of the screen plate 43. Starting the vibration motor 47 can drive the screen plate 43 to vibrate up and down. The vibration of the screen plate 43 can filter the raw materials.

[0029] like Figure 5 As shown, a servo motor 48 is fixedly connected to the top of the furnace body 1. A worm gear 49 is fixedly connected to the output end of the servo motor 48. A worm wheel 410 that meshes with the worm gear 49 is fixedly connected to the outer wall of the rotating rod 41. When the servo motor 48 is started, it drives the worm gear 49 to rotate. When the worm gear 49 rotates, it will drive the worm wheel 410 that meshes with it to rotate.

[0030] like Figure 6 As shown, the disassembly and assembly mechanism 5 includes a limiting block 51, which is slidably connected to the side wall of the collection box 44. A limiting rod 52 is fixedly connected to the side wall of the limiting block 51. The collection box 44 can be fixed below the sieve plate 43 by using the limiting rod 52 in conjunction with the limiting block 51.

[0031] like Figure 4 As shown, the disassembly and assembly mechanism 5 also includes a limiting spring 53. One end of the limiting spring 53 is fixedly connected to the bottom of the limiting block 51, and the other end of the limiting spring 53 is fixedly connected to the inner wall of the collection box 44. The elasticity of the limiting spring 53 can pull the limiting block 51 downward, so that the limiting block 51 slides down and resets on the side wall of the collection box 44.

[0032] like Figure 4 and Figure 6As shown, the disassembly and assembly mechanism 5 also includes a fixing plate 54, which is fixedly connected to the bottom of the screen plate 43. The fixing plate 54 has an inclined groove 55 and a slot 56. The outer wall of the limiting rod 52 is attached to the inner wall of the slot 56. The collection box 44 can be limited to the bottom of the screen plate 43 by the slot 56 cooperating with the limiting rod 52 and the limiting block 51. The slot 56 is perpendicular to the bottom of the fixing plate 54. One end of the inclined groove 55 is connected to the inside of the slot 56, and the other end of the inclined groove 55 is in an open state, through which the limiting rod 52 can enter and exit the inclined groove 55.

[0033] like Figure 1 - Figure 3 As shown, there are four sets of rotating rods 41. The four sets of rotating rods 41 are arranged in a circular array on the top of the furnace body 1 with the central axis of the melting pot 2 as the center. The sliders 42 on the outer wall of the four sets of rotating rods 41 are arranged in a stepped manner in a clockwise direction. The screen plate 43 on the side wall of the slider 42 at the highest position has the largest mesh size, while the screen plate 43 on the side wall of the slider 42 at the lowest position has the smallest mesh size, forming a gradient filtration structure from coarse to fine. The raw materials can be filtered four times from coarse to fine by the four sets of screen plates 43 with progressively smaller mesh sizes arranged in a stepped manner, thereby effectively filtering out impurities in the raw materials. The filtered raw materials can also automatically fall into the interior of the melting pot 2 for refining.

[0034] The working principle of this utility model is as follows: The slider 42 is elastically connected to the fixed block 45 by the return spring 46, allowing the slider 42 to slide up and down on the outer wall of the rotating rod 41. At this time, the vibration motor 47 is started, which drives the screen plate 43 to vibrate up and down. Simultaneously, the screen plate 43 drives the slider 42 to slide up and down on the outer wall of the rotating rod 41. The raw material to be filtered is then poured onto the highest screen plate 43. The raw material is initially screened by the screen plate 43 with the largest mesh size. Impurities at the screening point will fall into the collection box 44 for storage. At this time, as the screen plate 43 vibrates, the raw material on its surface will slide down to the next screen plate 43, allowing the screen plate 43 with a slightly smaller mesh size to screen the raw material again. By using four sets of screen plates 43 with progressively smaller mesh sizes, the raw material can be filtered four times, thereby effectively filtering out the impurities in the raw material. As the screen plate 43 vibrates, the filtered raw material will fall into the melting tank 2 for refining.

[0035] When it is necessary to remove the melting pot 2 and pour out the solution inside, the servo motor 48 is started to drive the worm gear 49 to rotate. At the same time, the rotation of the worm gear 49 will drive the worm wheel 410 meshing with it to rotate, so that the worm wheel 410 drives the rotating rod 41 to rotate. At this time, the rotating rod 41 will drive the slider 42 to rotate synchronously. The rotation of the slider 42 can drive the screen plate 43 to rotate in a circle around the rotating rod 41 as the center point, so that the screen plate 43 can be moved from above the melting pot 2 to the outside of the furnace body 1. At this time, the lifting ring 3 can be lifted by the hoisting equipment. With the hoisting equipment and the lifting ring 3, the melting pot 2 can be removed from the inside of the furnace body 1.

[0036] Push the limiting rod 52 to move it upward inside the slot 56, so that the limiting rod 52 moves to the connection between the slot 56 and the inclined groove 55. Then push the collection box 44 to move the limiting block 51, so that the limiting block 51 moves the limiting rod 52 from inside the slot 56 to inside the inclined groove 55, until the limiting rod 52 moves out of the inclined groove 55 from the opening of the inclined groove 55, so that the collection box 44 can be separated from the sieve plate 43, so that the impurities inside the collection box 44 can be cleaned.

[0037] When it is necessary to install the collection box 44 and the sieve plate 43 together, the top of the collection box 44 is attached to the bottom of the sieve plate 43. Then, the collection box 44 is pushed so that the limiting rod 52 on the side wall of the limiting block 51 is inserted into the inside of the inclined groove 55 through the opening of the inclined groove 55. At this time, under the guidance of the inclined groove 55, the limiting rod 52 will push the limiting block 51 upward, so that the limiting block 51 slides upward on the side wall of the collection box 44 and stretches the limiting spring 53. When the limiting rod 52 enters the slot 56 during the movement inside the inclined groove 55, the limiting spring 53 will pull the limiting block 51 downward, so that the limiting block 51 slides downward on the side wall of the collection box 44 and resets. At the same time, the limiting block 51 will drive the limiting rod 52 to insert into the inside of the slot 56. At this time, the collection box 44 can be limited to the bottom of the sieve plate 43 by the slot 56 in conjunction with the limiting rod 52 and the limiting block 51, thereby completing the installation of the collection box 44.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
