Technical Field

[0001] This utility model belongs to the field of aluminum alloy production technology, and in particular relates to an aluminum alloy modifier grinding device.

[0002] This application claims priority to the earlier application, application number 2024226484058, entitled "Aluminum Alloy Modifier Grinding Device," with a priority date of 2024-10-31. Background Technology

[0003] Currently, cast silicon-aluminum alloys are the most produced and widely used type of cast aluminum alloy. Silicon-aluminum alloys contain silicon, an element with relatively low density, resulting in a lower overall density and cost. However, they possess superior properties such as good thermal conductivity, high specific strength and stiffness, good plating performance with gold, silver, copper, and nickel, weldability to substrates, and ease of precision machining.

[0004] In actual production, silicon-aluminum alloys are typically subjected to modification treatment. Modification treatment refers to the addition of small amounts of other elements to the original alloy composition during alloy smelting to improve the metallographic structure and achieve a certain desired microstructure. Modification treatment usually involves adding modifiers, which is effective, inexpensive, and easy to implement. Existing modifiers are divided into two categories: single-element modifiers and composite modifiers; they are typically made by grinding compounds of the desired elements.

[0005] The existing technical solutions mentioned above have the following drawbacks: Currently, grinding is done by pressing the material onto a fixed grinding disc and squeezing and rotating it. The rotation drives the material to tear and crush it. However, the rotation speed of the grinding disc is fixed and cannot be increased according to the degree of grinding, and the grinding speed is relatively slow. Utility Model Content

[0010] As a preferred embodiment of the above technical solution, a feeding mechanism for feeding material into the feed inlet is installed on one side of the bracket. The lower surface of the first grinding disc is in contact with the upper surface of the second grinding disc.

[0012] As a preferred embodiment of the above technical solution, the feeding mechanism includes a feeding cylinder and a feeding auger. The feeding auger is rotatably installed inside the feeding cylinder. The upper end of the feeding cylinder is connected to a feeding pipe, and the other end of the feeding pipe is connected to the grinding cylinder. By driving the feeding auger to rotate, the bottom material is lifted through the feeding cylinder into the grinding cylinder.

[0013] As a preferred embodiment of the above technical solution, a guide plate is fixed inside the grinding cylinder. The guide plate is positioned above the first grinding disc and below the feeding pipe.

[0017] 1. A grinding gap is provided between the first grinding disc and the second grinding disc. The grinding gap gradually decreases from the center of the second grinding disc to the edge. The material to be ground is fed in through the feed port opened on the upper surface of the first grinding disc.

The material is ground when the first grinding disc and the second grinding disc move relative to each other. The ground material falls from the edge of the second grinding disc. The feed port is set near the center of the first grinding disc. Since the linear velocity of the material is greater closer to the edge between the first grinding disc and the second grinding disc, the grinding gap is smaller, and the grinding of the material is more thorough and faster, so that the material achieves the expected grinding effect when it is discharged.

[0018] 2. The drive shaft of the geared motor drives the second grinding disc to rotate relative to the support, causing the main gear to rotate in the forward direction. The rotation of the main gear drives the phase gear to rotate, causing the driven gear to rotate in the reverse direction. The first grinding disc rotates relative to the second grinding disc under the drive of the driven gear. A single geared motor synchronously realizes the forward and reverse rotation of the first and second grinding discs. The investment in the gear reduction equipment reduces costs and provides the rotational speed of the material during grinding, further making the grinding more thorough. Attached Figure Description

[0032] Figure 3 The illustration shows a specific embodiment of the present invention, in which the support 100 is fixed with a grinding cylinder 110, and the first grinding disc 310 and the second grinding disc 320 are both disposed inside the grinding cylinder 110; the lower end of the grinding cylinder 110 is provided with a discharge port; the placement of the first grinding disc 310 and the second grinding disc 320 inside the grinding cylinder 110 guides the discharge of the ground material, preventing the material from overflowing, and also facilitates the feeding mechanism 700 to feed the material, lifting the material to be ground to the upper end of the grinding cylinder 110, so as to facilitate its introduction into the feed port 311 for grinding.

[0033] As a specific embodiment of this utility model, the feeding mechanism 700 includes a feeding cylinder 710 and a feeding auger 730. The feeding auger 730 is rotatably installed inside the feeding cylinder 710.

[0037] Working principle: The drive shaft of the geared motor 500 drives the second grinding disc 320 to rotate relative to the support 100, causing the main gear 510 to rotate in the forward direction. The rotation of the main gear 510 drives the transformation gear 130 to rotate, causing the driven gear 150 to rotate in the reverse direction.

A grinding gap is provided between the first grinding disc 310 and the second grinding disc 320, and the grinding gap is formed by... The second grinding disc 320 gradually decreases in size from its center to its edge.

The material falls into the gap between the lower surface of the first grinding disc 310 and the upper surface of the second grinding disc 320. The material is ground when the first grinding disc 310 and the second grinding disc 320 move relative to each other. The ground material falls from the edge of the second grinding disc 320. The feed port 311 is located near the center of the first grinding disc 310. Since the linear velocity of the material is greater closer to the edge between the first grinding disc 310 and the second grinding disc 320, the grinding gap is smaller, and the grinding of the material is more thorough and faster, so that the material achieves the expected grinding effect when it is discharged.
