Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical material drying technology, and in particular to a metallurgical auxiliary material powder drying device. Background Technology
[0002] Powder metallurgy is a process technology that produces metal powders or uses metal powders as raw materials, and manufactures metal materials, composite materials and various types of products through forming and sintering. Powder metallurgy has similarities with the production of ceramics, both of which belong to powder sintering technology.
[0003] During the production process, most metallurgical auxiliary powders often contain moisture, necessitating the use of thermal drying equipment to dry them and reduce the impact of internal moisture on subsequent processing. While existing drying equipment can conveniently dry metallurgical auxiliary powders, it often fails to effectively dry the powder at the bottom of the conveyor belt during the conveying and drying process, resulting in poor drying effects. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a metallurgical auxiliary powder drying device, comprising a guide box (1), a support foot (2) and a guide barrel (3), wherein the support foot (2) is located below the guide box (1) and the guide barrel (3) is located above the guide box (1), a cover plate is slidably installed on the inner side of the guide barrel, a scraper is welded to the inner side of the guide box, a first support plate is welded to the inner side of the guide box, a scraper hook is welded to the surface of the first support plate, the side of the scraper hook away from the first support plate abuts against the surface of the conveying mechanism, a second support plate is welded to the inner side of the guide box, and the same scraper hook is welded to the surface of the second support plate.
[0006] Preferably, a drying trough is provided on the inner side of the guide box, a conveying mechanism is rotatably installed on the inner wall of the drying trough, and a guide groove is provided on the inner side of the guide box.
[0007] Preferably, the scraper is located above the conveying mechanism, the first support plate is located behind the scraper, and the second support plate is located behind the first support plate.
[0008] Preferably, the scraper hooks on the second support plate are staggered from the scraper hooks on the first support plate on the same horizontal plane.
[0009] Preferably, a guide plate is slidably installed on the inner side of the guide barrel, and an elastic component is slidably sleeved on the surface of the guide plate. The two ends of the elastic component are respectively fixedly installed on the surface of the guide plate and the inner side of the guide barrel.
[0010] Preferably, the scraper hook is also inclined.
[0011] Preferably, the surface of the feed box is welded with support feet, and the surface of the feed box is provided with a drying mechanism.
[0012] Preferably, the inner side of the guide box is provided with a cleaning groove, the inner side of the guide box is also inclined, a positioning plate is welded to the surface of the guide box, and a collection box is provided below the positioning plate.
[0013] Preferably, a guide ring is threaded onto the surface of the feed barrel, and the inner side of the guide ring and the surface of the elastic component are also inclined.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] (1) In this metallurgical auxiliary powder drying device, when the metallurgical auxiliary powder reaches the scraper on the first support plate, the scraper, by its own inclination, abuts against the conveying mechanism to form a turning operation on the metallurgical auxiliary powder at the lowest point of its surface.

[0016] (2) The metallurgical auxiliary powder drying device can collect the residual metallurgical auxiliary powder inside the guide box by setting an inclined shape inside the guide box when the conveying mechanism rotates. After the residual metallurgical auxiliary powder collected in the guide box is cleaned, the residual metallurgical auxiliary powder can be collected at the collection box through the positioning plate.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0027] Please see Figure 1-4 This utility model provides a technical solution: a metallurgical auxiliary powder drying device, including a guide box (1), a support foot (2) and a guide barrel (3). The support foot (2) is located below the guide box (1), and the guide barrel (3) is located above the guide box (1). The guide barrel (3) is welded to the surface of the support foot 2. A cover plate 4 is slidably installed on the inner side of the guide barrel 3. The support foot 2 is to provide certain support for the guide box 1 so that the operator can easily adjust and use the device. The cover plate 4 is used to shield and protect the guide barrel 3 when it is not in use.
[0028] Furthermore, a guide plate 5 is slidably installed on the inner side of the guide barrel 3, and an elastic component 6 is slidably sleeved on the surface of the guide plate 5. The two ends of the elastic component 6 are respectively fixedly installed on the surface of the guide plate 5 and the inner side of the guide barrel 3. A guide ring 7 is threadedly installed on the surface of the guide barrel 3, and the inner side of the guide ring 7 and the surface of the elastic component 6 are both inclined.
[0029] Specifically, by controlling the movement of the guide ring 7 on the surface of the guide barrel 3, the guide ring 7 can push the guide plate 5 to slide and adjust inside the guide barrel 3, thereby reducing the gap between the two sets of guide plates 5 after relative movement. At this time, the metallurgical auxiliary powder inside the guide barrel 3 can be adjusted for feeding. By adjusting the gap size of the guide plate 5 at the guide barrel 3, the amount of metallurgical auxiliary powder of different particle sizes can be fed at the same time, so that the metallurgical auxiliary powder has a certain anti-accumulation effect when it arrives at the guide box 1 for drying, thus ensuring the efficiency of drying the metallurgical auxiliary powder.
[0030] Furthermore, a drying mechanism 8 is provided on the surface of the feed box 1. The drying mechanism 8 is a material drying box. The drying mechanism 8 is an existing structure and will not be described in detail here.
[0031] Furthermore, a drying trough 9 is provided on the inner side of the feed box 1. A conveying mechanism 10 is rotatably installed on the inner wall of the drying trough 9. The function of the conveying mechanism 10 is to convey the metallurgical auxiliary powder so that the conveying mechanism 10 can carry the metallurgical auxiliary powder to the bottom of the drying mechanism 8 for drying operation.
[0032] Furthermore, a guide groove 11 is provided on the inner side of the guide box 1, which guides the metallurgical auxiliary powder inside the guide barrel 3.
[0033] Furthermore, a scraper 12 is welded to the inner side of the guide box 1. The scraper 12 is located above the conveying mechanism 10. The function of the scraper 12 is to scrape and flatten the metallurgical auxiliary powder guided at the guide trough 11, thereby reducing the drawback of poor drying effect caused by the accumulation of metallurgical auxiliary powder.
[0034] Furthermore, a first support plate 13 is welded to the inner side of the guide box 1. The first support plate 13 is located behind the scraper 12. A scraper hook 15 is welded to the surface of the first support plate 13. The side of the scraper hook 15 away from the first support plate 13 abuts against the surface of the conveying mechanism 10. A second support plate 14 is welded to the inner side of the guide box 1. The same scraper hook 15 is welded to the surface of the second support plate 14. The second support plate 14 is located behind the first support plate 13. The scraper hooks 15 on the second support plate 14 and the scraper hooks 15 on the first support plate 13 are staggered on the same horizontal plane. The shape of the scraper hooks 15 is also inclined.
[0035] Specifically, when the metallurgical auxiliary powder from the guide bucket 3 reaches the surface of the conveying mechanism 10 for conveying and drying, the metallurgical auxiliary powder is first scraped flat by the scraper 12. Then, the flattened metallurgical auxiliary powder is dried below the drying mechanism 8. When the metallurgical auxiliary powder reaches the scraper hook 15 on the first support plate 13, the scraper hook 15, by its own inclination, abuts against the conveying mechanism 10 to form a turning operation on the lowest metallurgical auxiliary powder on its surface. When the turned metallurgical auxiliary powder reaches the second support plate 14, the second support plate 14, through its own scraper hook 15 which is misaligned with the first support plate 13, turns the metallurgical auxiliary powder on the conveying mechanism 10 a second time. This results in good turning and drying of the material during conveying and drying, reducing the disadvantage that the bottom of the traditional metallurgical auxiliary powder is not easy to dry during conveying and drying, and thus improving the reliability of the drying operation of the metallurgical auxiliary powder.
[0036] Furthermore, a cleaning groove 16 is provided on the inner side of the guide box 1. The inner side of the guide box 1 is also inclined. A positioning plate 17 is welded to the surface of the guide box 1. A collection box 18 is provided below the positioning plate 17. By setting the inner side of the guide box 1 in an inclined shape, the residual metallurgical auxiliary powder when the conveying mechanism 10 rotates can be collected inside the guide box 1. After the residual metallurgical auxiliary powder collected in the guide box 1 is cleaned, the residual metallurgical auxiliary powder can be collected at the collection box 18 through the positioning plate 17.
[0037] Working principle: A metallurgical auxiliary powder drying device, when the metallurgical auxiliary powder from the guide bucket 3 reaches the surface of the conveying mechanism 10 for drying, the metallurgical auxiliary powder will first be scraped flat by the scraper 12, and then the scraped metallurgical auxiliary powder will be dried below the drying mechanism 8. When the metallurgical auxiliary powder reaches the scraper hook 15 on the first support plate 13, the scraper hook 15 will abut against the conveying mechanism 10 by its own inclination to form a turning operation on the metallurgical auxiliary powder at the lowest point of its surface. When the metallurgical auxiliary powder that has completed the turning reaches the second support plate 14, the second support plate 14 will turn the metallurgical auxiliary powder on the conveying mechanism 10 a second time by its own scraper hook 15 which is misaligned with the first support plate 13.
[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
