Description

Technical Field

[0001] This utility model relates to the field of fine aluminum powder quality detection technology, specifically to a fine aluminum powder purity detection device. Background Technology

[0002] Currently, aluminum powder produced from aluminum ingots often contains small amounts of impurities, such as aluminum oxide and silicon dioxide. After aluminum powder production, the purity is usually determined using EDTA titration. EDTA titration can determine the content of metallic aluminum (also known as active aluminum) in aluminum powder. This method provides accurate results, but its accuracy depends on the homogeneity of the test solution.

[0003] For example, CN 217033572 U discloses a device for detecting the purity of fine aluminum powder, which includes a box, a test tube rack, and a volumetric flask. The box has an internal chamber containing the test tube rack and volumetric flask. A heating coil is located at the bottom of the box, and an asbestos mesh is placed on the upper surface of the heating coil. The volumetric flask is placed on the upper surface of the asbestos mesh. A stirring rod is vertically mounted inside the volumetric flask and is connected to a micro motor via a coupling. The stirring rod can be freely detached from the coupling. The micro motor is fixed to the telescopic end of a telescopic sleeve, and the other end of the telescopic sleeve is fixed to a hydraulic cylinder, which is fixed to a support column. Multiple sets of test tube holes are provided on the upper shelf of the test tube rack, with rubber rings inside the holes. A heating cloth sleeve is located below the test tube holes on the test tube rack. This detection device provides convenient heating, uniform mixing, and strong practicality. However, the following problems still exist: 1. It requires staff to lift the support column to remove the stirring rod from the volumetric flask, and the degree of automation needs to be improved; 2. The telescopic sleeve of the hydraulic cylinder is a cantilever support structure, and the micro motor is fixed at the end of the cantilever support structure. During the process of driving the stirring rod to rotate, it will produce vibration, which is not conducive to the stability of the operation. Utility Model Content

[0004] The purpose of this invention is to provide a fine aluminum powder purity detection device with a reasonable structure and reliable operation that solves the above problems. On the one hand, the detection speed is greatly improved, and on the other hand, the working stability is strong.

[0005] The technical solution of this utility model is:

[0006] A device for detecting the purity of fine aluminum powder includes a detection chamber, a heating base at the bottom of the detection chamber, and a volumetric flask on the heating base. The key technical features are: two X-axis linear modules are arranged parallel to each other along the front and rear upper edges of the detection chamber; the sliders of the two X-axis linear modules are connected to a horizontal support plate; a bearing is fixed in the middle of the horizontal support plate; a T-shaped support sleeve is fixed to the inner ring of the bearing; a longitudinally multi-section telescopic cylinder passes through the T-shaped support sleeve; the upper edge of the T-shaped support sleeve extends to the outer side of the outer ring of the bearing and has a toothed structure; a drive gear meshing with the toothed structure and a motor connected to the gear shaft of the drive gear are supported above the horizontal support plate; a skirt portion connected to the T-shaped support sleeve is provided on the cylinder body of the longitudinally multi-section telescopic cylinder; and a stirring paddle is fixed to the lower end of the cylinder rod of the longitudinally multi-section telescopic cylinder.

[0007] In the above-mentioned fine aluminum powder purity detection device, the horizontal support plate is provided with a burette fixing sleeve on the bearing side, and the lower end of the burette passes through the burette fixing sleeve and is suspended above the volumetric flask.

[0008] The aforementioned fine aluminum powder purity detection device has a mounting base corresponding to the lower end of the drive gear axle and a right-angle support for fixing the motor on the horizontal support plate. The motor is located above the horizontal plane of the right-angle support, and the output end of the motor is connected and fixed to the upper end of the drive gear axle.

[0009] The beneficial effects of this utility model are:

[0010] 1. Horizontal support plates, as the supporting surface, provide better support stability during the mixing process compared to cantilever support structures.

[0011] 2. The stirring paddle can be lifted using a longitudinal multi-section telescopic cylinder, making it easy to remove the stirring paddle from the volumetric flask. This greatly improves the automation level and increases the testing speed. Attached Figure Description

[0017] The present invention will be described in detail with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the fine aluminum powder purity detection device includes a detection box 10, a heating base 13 located at the bottom of the detection box 10, and a volumetric flask 11 located on the heating base 13.

[0019] The detection box 10 has two X-axis linear modules 9 arranged in parallel along its front and rear upper edges, and the sliders of the two X-axis linear modules 9 are connected to a horizontal support plate 14.

[0020] A bearing 8 is fixed to the middle of the horizontal support plate 14, and a T-shaped support sleeve 5 is fixed to the inner ring of the bearing 8. A longitudinal multi-section telescopic cylinder 1 is inserted through the T-shaped support sleeve 5. The upper edge of the T-shaped support sleeve 5 extends to the outer side of the outer ring of the bearing 8 and has a toothed structure. Above the horizontal support plate 14, a drive gear 4 that meshes with the toothed structure and a motor 2 connected to the gear shaft of the drive gear 4 are also supported. The cylinder body of the longitudinal multi-section telescopic cylinder 1 has a skirt part that connects to the T-shaped support sleeve 5, and a stirring paddle 12 is fixed to the lower end of the cylinder rod of the longitudinal multi-section telescopic cylinder 1.

[0021] In this embodiment, the horizontal support plate 14 is further provided with a burette fixing sleeve 7 on the bearing side. The lower end of the burette 6 passes through the burette fixing sleeve 7 and is suspended above the volumetric flask 11. The horizontal support plate 14 is provided with a mounting seat corresponding to the lower end of the axle of the drive gear 4 and a right-angle support 3 for fixing the motor 2. The motor 2 is located above the horizontal plane of the right-angle support 3, and the output end of the motor 2 is connected and fixed to the upper end of the axle of the drive gear 4.

[0022] Working principle:

[0023] In use, aluminum powder and solution are added to the volumetric flask 11. The two X-axis linear modules 9 are activated, causing the horizontal support plate 14 and its components to reach above the volumetric flask 11. The longitudinal multi-section telescopic cylinder 1 is activated, its rod causing the stirring paddle 12 to sink into the solution. The motor 2 is then activated, driving the T-shaped support sleeve 5, the longitudinal multi-section telescopic cylinder 1, and the stirring paddle 12 to rotate synchronously via the drive gear 4 and its toothed structure. The stirring paddle 12 performs uniform stirring. After stirring is complete, the longitudinal multi-section telescopic cylinder 1 and the stirring paddle 12 are raised and reset. The X-axis linear module 9 then causes the horizontal support plate 14 and its components to reset. The lower end of the burette 6 is positioned above the volumetric flask 11, and the detection reagent is added to the volumetric flask 11 through the burette 6.

[0024] The X-axis linear module 9 once again drives the horizontal support plate 14 and its components to reach above the volumetric flask 11. The cylinder rod of the longitudinal multi-section telescopic cylinder 1 brings the stirring paddle 12 into the solution. The motor 2 is started again, and the stirring paddle 12 stirs again. After stirring evenly, the longitudinal multi-section telescopic cylinder 1 and the stirring paddle 12 are raised, reset, and moved away from above the volumetric flask 11, making it easier for staff to complete subsequent testing work.

[0025] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
