Description

Technical Field

[0001] This utility model relates to the field of alloy raw material processing technology, and more specifically, to a pretreatment device for high-temperature alloy raw material smelting. Background Technology

[0002] High-temperature alloys are metallic materials based on iron, nickel, and cobalt that can operate for extended periods at temperatures above 600°C and under certain stress. They possess excellent high-temperature strength, good resistance to oxidation and hot corrosion, and good fatigue performance and fracture toughness, among other comprehensive properties. They are also known as "superalloys" and are primarily used in aerospace and energy fields. High-temperature alloys are smelted in a vacuum induction furnace under full vacuum conditions. Since there is no space or equipment for slag removal during smelting and casting, refined raw material smelting and pre-treatment of the raw materials entering the furnace are essential.

[0003] Due to market competition and cost factors, companies in the industry need to use a large amount of recycled materials for smelting. However, recycled materials generally contain varying degrees of contaminants. If they are not thoroughly cleaned and pretreated, they will seriously affect the quality of high-temperature alloys and the normal operation of production.

[0004] The general steps of high-temperature alloy raw material processing include: sorting, crushing, cleaning, and drying. The quality of the master alloy from the smelting of the scrap depends on the cleaning process. The key to the cleaning quality is the crushing size. Small and uniform scraps are easier to clean, resulting in a high purity master alloy. After crushing, the alloy raw materials need to be screened for further processing. During the feeding and crushing process of the alloy raw materials, the dust carried by the alloy raw materials themselves, as well as the tiny metal particles generated during the crushing process, can easily cause dust pollution during the feeding, loading, and screening processes. This can affect the working environment of the alloy raw material processing and potentially harm the health of the workers. Utility Model Content

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0038] like Figure 1-7As shown, a pretreatment device for smelting high-temperature alloy raw materials includes: a processing box 1; a crushing assembly 2 connected to the top of the processing box 1; a collecting funnel 3 installed on the crushing assembly 2; a screening assembly 4 disposed inside the processing box 1 and placed below the crushing assembly 2; a distribution box 5 fixedly installed inside the processing box 1; a collecting hopper 6 connected to the top of the distribution box 5; a circulating hopper 7 fixed inside the processing box 1; a circulating conveying assembly 8 inclinedly fixed outside the processing box 1; and a dust removal assembly 9 installed on the processing box 1.

[0039] The crushing component 2 is adapted to process and shred the alloy raw material into the required size;

[0040] The screening component 4 is suitable for separating alloy raw materials of different sizes;

[0041] The circulating conveying component 8 is adapted to convey a portion of the alloy raw materials screened by the screening component 4 to the collecting funnel 3.

[0042] The dust removal component 9 is suitable for collecting the metal dust generated during the processing of the alloy raw materials. In conjunction with the distribution box 5, it further separates the sieved alloy raw materials according to size. When the dust removal component 9 is activated, as the worker adds the alloy raw materials to the crushing component 2 through the collection funnel 3, the dust generated during the feeding process is sucked into the processing box 1 and collected. After the alloy raw materials are crushed, they fall into the processing box 1 and are vibrated and sieved by the screening component 4. During the separation of different sizes, the dust adhering to the alloy raw materials during the vibrating screening is detached, and the resulting dust is also collected. This effectively handles the dust carried by the alloy raw materials during collection and crushing, and also prevents dust from being generated when the alloy raw materials are discharged after screening. This avoids pollution of the alloy raw material processing environment and prevents harm to the workers. The large-sized alloy raw materials can fall into the circulating hopper 7 and then be transported to the collection funnel 3 by the circulating conveying component 8, where they are further crushed by the crushing component 2, reducing the workload of repeated collection and handling by the staff. The smaller-sized alloy raw materials screened out by the screening component 4 will fall into the distribution box 5 through the collection hopper 6. At this time, the airflow filtered by the dust removal component 9 will perform air separation on the smaller-sized alloy raw materials entering the distribution box 5, thus separating the alloy raw materials that are too small or similar in size but lighter from the required alloy raw materials. This ensures that the alloy raw materials are uniform in size after processing and do not contain many non-metallic impurities, making the subsequent processing of the alloy raw materials more convenient and the processing effect better.

[0043] Optionally, the dust removal assembly 9 includes a gas collection hood 10 connected to the top of the processing box 1, an exhaust hood 11 connected to the side of the processing box 1 and placed at the collection hopper 6, a dust collection box 12 installed in the processing box 1, a dust removal fan 13 fixed to the outer wall of the processing box 1, an air inlet pipe 14 connected at one end to the gas collection hood 10 and at the other end to one side of the dust collection box 12, an air delivery pipe 15 connected at one end to the air inlet of the dust removal fan 13 and at the other end to the other side of the dust collection box 12, an exhaust pipe 16 connected at one end to the air outlet of the dust removal fan 13 and at the other end to the exhaust hood 11, a filter plate 17 movably inserted into the dust collection box 12, and a collection drawer 18 movably disposed in the dust collection box 12.

[0044] The other end of the air inlet pipe 14 is located below the filter plate 17, and the other end of the air delivery pipe 15 is located above the filter plate 17. When the alloy raw material falling into the processing box 1 is vibrated and screened by the screening component 4, the dust removal fan 13 operates, drawing air from the dust collection box 12 through the air delivery pipe 15, creating a negative pressure in the dust collection box 12. With the cooperation of the air inlet pipe 14 and the air collection hood 10, air is drawn from the top of the processing box 1, controlling the negative pressure to be generated in the processing box 1. This allows the dust generated during the crushing and vibration of the alloy raw material to be drawn into the dust collection box 12. When the alloy raw material to be processed is added to the collection funnel 3, no dust is generated. After dust removal, the alloy raw material is then processed... During material handling, no dust will be generated, thus avoiding pollution of the alloy raw material processing environment and preventing impact on the health of workers. The dust transported to the dust collection box 12 through the air inlet pipe 14 will be blocked by the filter plate 17 and fall into the collection drawer 18, making it convenient for workers to collect and utilize the metal powder in the dust. While dust removal is carried out in the processing box 1, the airflow filtered by the filter plate 17 will be transported to the exhaust hood 11 through the air supply pipe 15 and the exhaust pipe 16. The smaller alloy raw materials after screening will be air-separated, allowing the smaller alloy raw materials to be further classified according to weight, effectively improving the uniformity of the processed alloy raw materials and facilitating the subsequent impurity removal process.

[0045] Optionally, the crushing assembly 2 includes a crushing box 19 disposed on the upper surface of the processing box 1, a discharge hopper 20 installed at the bottom of the crushing box 19 and connected to the processing box 1, two rotating shafts 21 symmetrically rotatably installed inside the crushing box 19, a plurality of crushing wheels 22 fixedly sleeved on the outside of the two rotating shafts 21, and two reduction motor sets 23 installed on the outside of the crushing box 19.

[0046] The output ends of the two geared motor sets 23 are respectively fixedly connected to the two rotating shafts 21;

[0047] The collecting funnel 3 is installed on the top of the crushing box 19. When in use, the two reduction motors 23 work synchronously, driving the two rotating shafts 21 to rotate synchronously in opposite directions. At the same time, several crushing wheels 22 rotate, so that the alloy raw material falls into the crushing box 19 through the collecting funnel 3 and is torn apart by the rotating crushing wheels 22. The crushed alloy raw material can fall into the processing box 1 through the discharge hopper 20 for further processing.

[0048] Optionally, the screening assembly 4 includes a screening frame 24 disposed in the processing box 1, a screening screen 25 inclinedly disposed in the screening frame 24, a collection hopper 26 installed in the screening frame 24 and placed below the screening screen 25, and two vibration motors 27 fixed in the screening frame 24.

[0049] The upward-sloping end of the screening screen 25 is located below the discharge hopper 20, and the downward-sloping end of the screening screen 25 is located above the circulation hopper 7.

[0050] The discharge end of the collecting hopper 26 is located at the top of the collecting hopper 6. As the alloy raw material falls onto the screening screen 25 through the crushing component 2, the two vibrating motors 27 control the screening frame 24 to drive the screening screen 25 to vibrate up and down, thus vibrating and screening the alloy raw material falling onto the screening screen 25. This causes the larger alloy raw material to fall into the circulating hopper 7 and be screened, while the smaller alloy raw material falls into the collecting hopper 26 and enters the collecting hopper 6. This allows the larger alloy raw material to be crushed again through the circulating conveying component 8, while the smaller alloy raw material can fall into the distribution box 5 for further separation. This facilitates the full utilization of the alloy raw material by the staff and ensures the standardization of the processed alloy raw material, which is convenient for the continued processing of the alloy raw material.

[0051] Optionally, the screening assembly 4 further includes several support platforms 28 fixed to the inner wall of the crushing box 19, several support seats 29 fixed to the screening frame 24 and corresponding to the support platforms 28, several auxiliary springs 30 fixed between the support platforms 28 and the support seats 29, several positioning balls 31 movably installed on the upper end of the outer wall of the screening frame 24, and several positioning grooves 32 formed on the inner wall of the crushing box 19 and corresponding to the positioning balls 31. When the two vibration motors 27 drive the screening frame 24 to vibrate, the support platforms 28, support seats 29 and auxiliary springs 30 are provided. Springs 30 can support and dampen the screening frame 24, preventing the screening screen 25 from breaking or deforming during use, and also serve as vibration isolation and main vibration. Several auxiliary springs 30 can isolate the direct impact of external vibration on the screening frame 24 and the screening screen 25, reducing the interference of external vibration on the screening effect. In addition, several auxiliary springs 30 can ensure that the screening frame 24 vibrates according to the set frequency and amplitude, thereby improving screening efficiency. At the same time, several positioning balls 31 will move in several positioning grooves 32 when the screening frame 24 vibrates, thereby limiting the vibration range of the screening frame 24 and avoiding collision with the processing box 1, which would cause excessive noise.

[0052] Optionally, the material distribution box 5 is provided with a first material cavity 33 and a second material cavity 34, and a first guide plate 35 and a second guide plate 36 are respectively inclinedly disposed in the first material cavity 33 and the second material cavity 34, respectively connected to the first material cavity 33 and the second material cavity 34, and extending to the outside of the processing box 1 through a first discharge pipe 37 and a second discharge pipe 38.

[0053] The first material chamber 33 is located directly below the discharge port of the collection hopper 6. During use, the alloy raw materials that fall into the collection hopper 6 after being screened by the screening component 4 will enter the distribution box 5. At this time, under the blowing of the gas discharged from the exhaust hood 11 in the dust removal component 9, the lighter alloy raw materials will fall into the second material chamber 34 and be discharged from the processing box 1 by the second guide plate 36 and the second discharge pipe 38. The qualified alloy raw materials will fall into the first material chamber 33 and be discharged from the processing box 1 by the first guide plate 35 and the first discharge pipe 37. This makes the alloy raw materials discharged from the first discharge pipe 37 uniform in size, which is convenient for subsequent cleaning and impurity removal of the alloy raw materials. At the same time, alloy raw materials of the same volume but containing more non-metallic impurities can also be separated out, which is convenient for further processing of the alloy raw materials.

[0054] Optionally, the circulating conveying assembly 8 includes a screw conveyor 39 that is inclined and fixed on the outer wall of the processing box 1, a circulating feeding pipe 40 with one end connected to the lower end of the screw conveyor 39 and the other end connected to the processing box 1, and a circulating discharge pipe 41 with one end connected to the upper end of the screw conveyor 39.

[0055] The other end of the circulating feed pipe 40 is located at the outlet of the circulating hopper 7, and the other end of the circulating discharge pipe 41 is located at the inlet of the collecting funnel 3. In use, after being screened by the screening component 4, the larger alloy raw materials will fall into the circulating hopper 7, and then be fed into the screw conveyor 39 through the circulating feed pipe 40. The screw conveyor 39 will then continuously transport the larger alloy raw materials upward, so that the larger alloy raw materials can be transported to the collecting funnel 3 through the circulating discharge pipe 41, and then undergo secondary crushing through the crushing component 2. This reduces the amount of manual labor and improves the overall crushing efficiency.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
