Description

Technical Field

[0001] The utility model relates to the field of stirring devices, in particular to a planetary powder vacuum stirring device. Background Art

[0002] Uniform, high-purity and high-efficiency mixing of multi-component powders has always been the basic requirement for powder application in many industries. Among the existing stirring devices, the drum type is the mainstream mixing method for mechanical mixing of powders. The powder is placed in the barrel, 2 to 4 times of stirring alloy balls are added, liquid paraffin, rubber and other molding agents are added, and then filled with alcohol. After sealing, the machine is turned on, and the barrel rotates horizontally at 60 to 120 rpm. The alloy balls roll up and down along the barrel wall, driving the powder to roll and stir. Usually, after stirring for 36 to 48 hours, the alcohol is filtered, the powder is dried and set aside; or improvements are made on the basis of the drum type, which effectively improves the mixing efficiency and uniformity. The principle is to use the center of the "V"-shaped barrel as the rotation axis, and the V barrel rolls up and down, which increases the up and down rolling distance of the stirring alloy balls and increases the mixing intensity of the powder. Usually, the stirring is completed in about 30 hours; the existing device can only use one machine and one material, and cannot mix multiple powder mixtures at the same time. For this reason, we propose a planetary powder vacuum stirring device. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 - Figure 2 The figure shows a planetary powder vacuum stirring device of the utility model, comprising a support base 1, wherein the support base 1 is rotatably connected to two sets of rotating shafts 2 through bearings, and the ends of the two sets of rotating shafts 2 that are away from each other are respectively fixedly connected to a set of public rotating disks 3, and a set of mixing barrel assemblies 4 are respectively installed on the two sets of public rotating disks 3, and the four sets of helical gears 1 401 in the mixing barrel assembly 4 are meshed with helical gears 2 5, and the two sets of helical gears 2 5 are respectively fixedly connected to a set of support tubes 6, and the two sets of support tubes 6 are respectively fixedly installed on the two ends of the support base 1.

[0018] The rotating shaft 2 passes through the inner cavities of the two groups of support tubes 6 and the two groups of bevel gears 5, and the rotating shaft 2 does not contact the inner walls of the two groups of support tubes 6 and the two groups of bevel gears 5; so that the support tubes 6 and the bevel gears 5 will not affect the normal rotation of the rotating shaft 2.

[0019] The mixing barrel assembly 4 includes four groups of mixing barrels 402, each of which is threadedly connected to a group of barrel covers 403, each of which is provided with a group of vacuum exhaust valves 404, each of which is fixedly connected to a group of rotating rings 405 at the bottom of the four groups of mixing barrels 402, each of which is rotatably connected to the inner side of the rotating disk 3, each of which is fixedly connected to a group of self-rotating rods 406 at the bottom of the four groups of mixing barrels 402, each of which is rotatably connected to the rotating disk 3 through bearings, each of which is fixedly connected to a group of helical gears 1 401, each of which is meshed with a group of helical gears 2 5, and the mixing barrels 402 are fixedly connected to a group of rotating rings 405 at the bottom of the four groups of mixing barrels 402. Each of the mixing barrels 402 is connected to a discharge pipe 407 and a valve is installed on the discharge pipe 407. When in use, a proper amount of powder is added to each mixing barrel 402. After the addition is completed, the mixing barrel 402 is vacuum-sucked in conjunction with an external device (this is a prior art and will not be described in detail), so that the powder mixture is stirred under vacuum conditions. The rotation of the rotating shaft 2 will drive the two sets of revolving disks 3 to rotate, and the rotation of the two sets of revolving disks 3 will drive the eight sets of mixing barrels 402 to revolve around the rotating shaft 2 as the center point. In the process of the rotation of the mixing barrel 402, since the bevel gear 1 401 is meshing with the bevel gear 2 5, the bevel gear 1 401 will rotate at this time, and the rotation of the bevel gear 1 401 causes the mixing barrel 402 to rotate.

[0020] The angles between the eight groups of mixing barrels 402 and the rotating shaft 2 are all 45°; the mixing barrel 402 undergoes revolution and rotation, and the angle with the rotating shaft 2 is 45°, so that the mixing movement of the powder and the alloy mixing balls has no dead angle, and the mixing efficiency is greatly improved.

[0021] The ends of the two groups of rotating shafts 2 that are close to each other are fixedly connected to the two end driving ends of the reducer 7, and the two groups of rotating shafts 2 are rotatably connected to a group of stable seats 8 through bearings; when in use, starting the reducer 7 will drive the two groups of rotating shafts 2 to rotate; it should be noted that the reducer 7 is a prior art, and the reducer 7 uses a reducer with two driving ends.

After the addition is completed, the mixing barrel 402 is vacuum-sucked in conjunction with an external device (this is a prior art and will not be described in detail), so that the powder mixture is stirred under vacuum conditions; starting the reducer 7 will drive the two sets of rotating shafts 2 to rotate, and the rotation of the two sets of revolving disks 3 will drive the eight sets of mixing barrels 402 to revolve around the rotating shaft 2 as the center point; during the rotation of the mixing barrel 402, since the bevel gear 1 401 is meshed with the bevel gear 2 5, the bevel gear 1 401 will rotate at this time, and the rotation of the bevel gear 1 401 causes the mixing barrel 402 to rotate on its own; the mixing barrel 402 undergoes revolution and rotation, so that the mixing barrel 402 can operate 360° without dead angles, and the angle between the mixing barrel 402 and the rotating shaft 2 is The angles are all 45°, which increases the up-and-down, front-and-back, and left-and-right movement of the powder and the alloy mixing balls in the mixing barrel, improves the mixing efficiency, and makes the mixing movement of the powder and the alloy mixing balls free of any dead angles, greatly improving the mixing efficiency; a set of vacuum exhaust valves 404 are provided on the barrel cover 403 of the mixing barrel 402, and after adding materials, the mixing barrel 402 is used in conjunction with an external device to perform vacuum suction, and through the coordinated use of a vacuum environment and efficient mixing, the amount of alloy mixing balls is increased by 1 to 2 times, greatly reducing the amount of alloy mixing balls; when the new type is used, pure mixing is achieved, and there is no need to add molding agents such as rubber and paraffin, no need for alcohol as a mixing medium for mixing, no need for subsequent filtering of alcohol, and no cumbersome processes such as drying the mixed material. Vacuum mixing is used to greatly improve efficiency and greatly reduce impurity pollution.
