Description

Technical Field

[0001] This utility model relates to the field of steel powder manufacturing technology, specifically to a pretreatment and drying device for spray-formed steel powder. Background Technology

[0002] High-speed steel powder spraying is an innovative metal forming process that manufactures high-precision, high-performance metal parts by spraying high-speed steel powder and subjecting it to specific treatments. This method combines the advantages of powder metallurgy and spraying forming technologies, injecting new vitality into modern manufacturing. Based primarily on the principles of powder metallurgy, high-speed steel powder of appropriate particle size is first selected and uniformly sprayed onto a predetermined location using specialized equipment. Subsequently, through processes such as heating and pressing, metallurgical bonding occurs between the powder particles, ultimately forming dense metal parts. The steel powder used is micron-sized metal particles produced through atomization metallurgy technology.

[0003] In the production process of steel powder, in order to avoid oxidation and other phenomena that lead to rust, the powder needs to undergo surface modification treatment in advance. For example, the natural porous oxide layer on the surface of the metal powder can be removed by plasma etching, followed by inorganic / organic coating to form a dense artificial protective layer, which reduces the oxygen content and improves the oxidation resistance. Then, the powder is immersed in a passivation solution, such as methyl benzotriazole solution, to form a protective film that isolates oxygen. The film-forming substance and nanomaterials can form a rust-proof protective layer. After treatment, it is necessary to thoroughly clean and dry.

[0004] When the steel powder undergoes anti-oxidation treatment and is then cleaned and dried, mechanical dehydration and thermal drying are commonly used. During the drying process, a stirring structure is typically used to break up any agglomerated powder, thus aiding the drying process. However, since both the drying and breaking structures are designed with a cylindrical structure, most of the steel powder ends up at the bottom of the cylinder after being poured in, making it difficult to evenly break up the agglomerated powder. This affects the subsequent drying efficiency and quality. Therefore, we propose a pretreatment and drying device for spray-formed steel powder. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

A disintegration motor is fixed on one side of the top end of the adjustment frame, and a disintegration shaft is axially connected to one end of the disintegration motor. A disintegration rod is fixed to the outer wall of the disintegration shaft. A bearing sleeve is sleeved and fixed on the other side of the top end of the adjustment frame, and a cover is fixed around the outer wall of the bearing sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This pretreatment drying device uses a drying drum as its main body. The horizontal structure of the drying drum and the internal drying chamber are used to dry steel powder. With the longitudinal rotation of the drying drum and the stirring baffle, the powder inside can be continuously turned up and down, thus avoiding the phenomenon of powder settling at the bottom and not being able to be effectively dispersed. With the electric heating rod embedded in the ring cloth, the cavity can be heated evenly, thereby quickly evaporating the moisture of the powder and discharging it from the filter frame, improving drying efficiency and quality.

The cover rotates with the drying drum and rotates synchronously with the locking pins on the inner wall of the annular groove to prevent slippage and maintain the stability of the overall dispersing process.

[0028] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This utility model provides, for example Figure 1-6 The device for pretreatment and drying of spray-formed steel powder shown includes a drying rack 1, a dispersing rack 2 on one side of the top surface of the drying rack 1, a base frame 101, and an adjustment groove 102 on the top surface of the base frame 101. A threaded shaft 103 is connected to the central shaft inside the adjustment groove 102, and an adjustment motor 104 is connected to one end of the threaded shaft 103. A wall frame 105 is fixed on the other side of the top surface of the base frame 101. A drive motor 106 is fixed to the center of one side of the wall frame 105. A drying drum 107 is connected to one side of the shaft of the drive motor 106. An annular groove 108 is opened on one side of the drying drum 107, and a retaining post 109 is opened on both sides of the inner wall of the annular groove 108. A drying chamber 110 is opened inside the drying drum 107, and a stirring baffle 111 is fixed around the inner wall of the drying chamber 110. An electric heating rod 112 is embedded around the inner wall of the drying chamber 110.

[0031] To ensure uniform drying of steel powder during the processing of this pretreatment drying device, such as Figure 1-3As shown, this pretreatment drying device uses a drying drum 107 as the main body. The steel powder is dried through the horizontal structure of the drying drum 107 and the internal drying chamber 110. With the longitudinal rotation of the drying drum 107 and the stirring baffle 111, the powder inside can be continuously turned up and down, thereby avoiding the phenomenon of powder settling at the bottom and not being able to be effectively dispersed. With the electric heating rod 112 embedded in the ring cloth, the internal cavity can be heated evenly, thereby quickly evaporating the moisture of the powder and discharging it from the filter frame 208, improving drying efficiency and quality.

[0032] When the filter frame 208 and the cover 207 are opened or closed, they can slide and adjust within the adjustment groove 102 in conjunction with the drive of the threaded shaft 103, thereby forming a stable opening and closing process of the cover 207, which provides convenience for the input and use of materials.

[0033] like Figure 4-6 As shown, the disintegration frame 2 includes an adjustment frame 201, and guide rail blocks 202 are fixed on both sides of the bottom end of the adjustment frame 201. A disintegration motor 203 is fixed on one side of the top end of the adjustment frame 201, and a disintegration shaft 204 is shaft-connected to one end of the disintegration motor 203. A disintegration rod 205 is fixed on the outer wall of the disintegration shaft 204. A bearing sleeve 206 is sleeved and fixed on the other side of the top end of the adjustment frame 201, and a cover 207 is fixed around the outer wall of the bearing sleeve 206. A filter screen frame 208 is embedded in the inner wall of the cover 207, and one side of the inner wall of the cover 207 is fastened to the annular groove 108 of the drying drum 107.

[0034] To facilitate the handling and placement of steel powder and the breaking up of clumps, such as Figure 2-5 As shown, this pretreatment drying device can drive the dispersing shaft 204 to rotate via the dispersing motor 203, thereby causing the dispersing shaft 204 to drive the surrounding dispersing rods 205 to disperse the powder clumps inside the drying chamber 110. The cover 207 can rotate with the drying drum 107 and rotate synchronously with the locking pin 109 on the inner wall of the annular groove 108 to prevent slippage and maintain the stability of the overall dispersing process.

[0035] In summary, when using this pretreatment drying device, the user first puts the steel powder material to be dried into the drying chamber 110. Then, the adjusting motor 104 is started to drive the threaded shaft 103 to rotate. The rotating threaded shaft 103 drives the connected adjusting frame 201 to slide and adjust along the adjusting groove 102. At this time, the cover 207 of the adjusting frame 201 is engaged with the annular groove 108 on one side of the drying drum 107 and is simultaneously engaged with the locking pin 109. Then, the drive motor 106 and the heating rod 112 are turned on. The drive motor 106 drives the drying drum 107 to rotate. The rotating drying drum 107, together with the stirring baffles 111 arranged around the inside drying chamber 110, continuously turns the steel powder up. At the same time, the dispersing motor 203 drives the dispersing shaft 204 and the connected dispersing rod 205 to rotate, breaking up the clumps of powder. Then, the residual moisture in the powder is evaporated by heating and slowly discharged from the filter frame 208, completing the pretreatment process.

Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
