Description

Technical Field

[0001] This utility model relates to the field of alloy powder sieving technology, specifically to an alloy powder sieving device that facilitates screen replacement. Background Technology

[0002] Alloy powder is a powdery substance made from two or more metallic elements, or metallic and non-metallic elements, through a certain process. It has a wide range of applications in many fields such as metallurgy, machinery, electronics, and aerospace. Its particle size distribution, particle shape and other characteristics directly affect the quality and performance of subsequent processed products.

[0003] Screening is an indispensable and crucial step in the production and processing of alloy powders. Through screening, alloy powders of different particle sizes can be separated to meet the stringent requirements of different products for the particle size of alloy powders, thereby ensuring the stability and reliability of the products.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an alloy powder sieving device that facilitates screen replacement, including a base 1, a plurality of first springs 2 on the base 1, a box 3 on the top of the plurality of first springs 2, a feed pipe 5 connected to the top of the box 3, a vibration motor 4 on the bottom, a discharge port 3-5 on one side wall of the box 3, a plurality of first through grooves 3-1 on the box 3, a moving frame 6 horizontally sliding in the plurality of first through grooves 3-1, the bottom of the moving frame 6 being inclined and having an opening on the lower side, a plurality of filter screens 13 on the bottom of the moving frame 6, a plurality of partitions 7 for separating the plurality of filter screens 13 inside the moving frame 6, the filter screens 13 on the moving frame 6 having different aperture sizes, the filter screens 13 on the upper moving frame 6 having larger aperture sizes than the filter screens 13 on the lower moving frame 6, and a plurality of limiting components for fixing the plurality of moving frames 6 on the box 3.

[0019] In this embodiment, there are four first springs 2, which are evenly distributed between the box body 3 and the base 1; the feed pipe 5 is located on the top of the box body 3 on the side higher than the filter screen 13; the bottom of the box body 3 is a slope, and the outlet 3-5 is located on the lower side of the bottom of the box body 3; when the limiting component fixes the mounting frame, the position of the partition 7 or the side wall of the mounting frame can correspond to the position of the side wall of the box body 3 to prevent alloy powder from falling out from the edge gaps during the screening process.

[0020] As an embodiment of this utility model, a first sliding groove 3-2 is provided on the box body 3, and a sliding strip 6-1 is provided at the bottom of the moving frame 6. The sliding strip 6-1 is horizontally slidably disposed in the first sliding groove 3-2.

[0021] In this embodiment, the first groove 3-2 limits the slider 6-1, so that the moving frame 6 does not move diagonally downward when it moves horizontally in the first groove 3-1.

[0022] As an embodiment of this utility model, each set of limiting components includes a plug rod 9, a lever 10, a telescopic rod 11, and a second spring 12. A second sliding groove 3-3 and a second through groove 3-4 are provided on the side wall of the housing 3. A horizontal plate 8 is provided on the moving frame 6 near the lower end. Insertion holes 14 are provided on the moving frame 6, the horizontal plate 8, and the housing 3. The plug rod 9 is vertically slidably disposed in the first sliding groove 3-2 and can be inserted into the insertion hole 14. The telescopic rod 11 is disposed between the side wall of the second sliding groove 3-3 and the plug rod 9. The second spring 12 is sleeved on the telescopic rod 11. The lever 10 is connected to the plug rod 9 and is vertically slidably disposed in the second through groove 3-4.

[0023] In this embodiment, when the insert rod 9 is inserted into the insertion hole 14 opened on the moving frame 6, the horizontal plate 8 and the box 3, the moving frame 6 can be limited in the horizontal direction to prevent the moving frame 6 from moving during the screening process.

[0024] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0025] The working principle and usage process of this utility model are as follows: Before sieving, the positions of multiple filter screens 13 on the housing 3 are adjusted according to the requirements of alloy powder sieving, so that the filter screens 13 that meet the sieving requirements are moved into the housing 3. Specifically, the operator manually moves the lever 10 upward, which drives the connected insertion rod 9 to move vertically upward in the second slide groove 3-3. When the insertion rod 9 moves, the telescopic rod 11 and the spring retract. When the insertion rod 9 is pulled out from the insertion hole 14 on the moving frame 6 and the horizontal plate 8, the operator pushes the moving frame 6 horizontally, so that the filter screens 13 that meet the sieving requirements are moved into the housing 3. The operator releases the lever 10, and under the elastic force of the second spring 12, the insertion rod 9 is reinserted into the insertion hole 14 on the horizontal plate 8, the moving frame 6, and the housing 3. The filter screens 13 on other moving frames 6 are adjusted and fixed in the same way. After adjusting the filter screen 13, the vibration motor 4 located at the bottom of the housing 3 is started. The vibration motor 4 drives the housing 3 to vibrate, and the alloy powder is uniformly fed into the feed pipe 5. After being screened by the filter screen 13 on each moving frame 6, the smaller particles fall downwards, while the larger particles move obliquely downwards along the inclined surface of the filter screen 13. Finally, they fall into the collection component through the opening on the lower side of the moving frame 6 (collection components are set at the outlet of each moving frame 6 and the discharge port 3-5 of the housing 3 for collection). This utility model adjusts the position of the filter screen 13 on each moving frame 6 on the housing 3 so that the filter screen 13 that meets the requirements moves into the housing 3. During adjustment, it is only necessary to manually move the lever 10 on the limiting component and then push the moving frame 6. The operation is convenient, time-saving, labor-saving and improves work efficiency.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
