Description

Technical Field

[0001] The utility model relates to the technical field of powder mixing equipment, in particular to a stirring device for continuous powder mixing. Background Art

[0002] Powder mixing is to mix two or more powders evenly by some means (mainly mechanical method, chemical method, etc.) to obtain a material with a new composition. The uniformity of powder mixing has a direct impact on whether the composition distribution of the final sample is uniform and whether there is segregation, which in turn affects its performance.

[0003] The patent network announcement number CN210875048U discloses a powder mixing and stirring device for a high-speed powder mixer. The utility model realizes rapid exchange and cooling of heat transferred to the casing through the casing spiral plate and the circulating cooling water pipe during mixing. Through the interface spiral plate, driven gear, stirring spiral knife and supporting components, it is realized that during mixing, the stirring spiral knife rotates in the opposite direction to the casing, so that the material rises and falls onto the casing spiral plate under the action of centrifugal force, ensuring uniform mixing and improving the mixing efficiency.

[0004] Because the entire casing of the above-mentioned equipment rotates, part of the powder will adhere to the inner wall of the casing, resulting in poor powder mixing effect, so it needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide a stirring device for continuous powder mixing to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a stirring device for continuous powder mixing, comprising a swing mechanism, a stirring mechanism is installed on the top of the swing mechanism, a mounting seat is installed on the right side of the stirring mechanism, and a motor is fixedly connected to the right side of the mounting seat;

[0007] The stirring mechanism includes a stirring shaft, which is fixedly connected to the left side of the motor. The stirring shaft is rotatably connected to a first cover plate and a second cover plate near both ends. The first cover plate and the second cover plate are fixedly connected to a stirring tank on the inner sides. The stirring shaft is fixedly connected to stirring blades near both sides in the stirring tank.

[0008] Preferably, the first cover plate and the second cover plate are both interference-fitted with a first bearing, and the first cover plate and the second cover plate are both rotatably connected to the stirring shaft via the bearing.

[0009] Preferably, the first cover plate and the second cover plate outer ring are both fixedly connected with mounting plates, and the mounting plates are in a triangular shape.

[0010] Preferably, the stirring blades are spiral-shaped, and the stirring blades at both ends of the stirring shaft are symmetrically distributed with respect to each other.

[0011] Preferably, a feed port is provided at the top of the stirring tank, and a feed cap is threadedly connected to the top of the feed port.

[0012] Preferably, the swing mechanism includes a fixed plate, the fixed plate is fixedly connected to the outside of the mounting plate, a rotating frame is fixedly connected to the bottom of the fixed plate, a swing shaft is fixedly connected to the middle of the bottom of the rotating frame, the swing shaft is rotatably connected to a base near the bottom, a half gear is fixedly connected to the swing shaft between the base and the rotating frame, a gear is meshed on the right side of the half gear, and a second motor is fixedly connected to the middle of the gear.

[0013] Optionally, a fixed sleeve is fixedly connected in the middle of the base, a second bearing is fixedly connected in the middle of the fixed sleeve, the inner ring of the second bearing is fixedly connected to the outer wall of the swing shaft, a mounting plate is fixedly connected to the bottom of the fixed sleeve, and the bottom of the mounting plate is fixedly connected to the top of the second motor.

[0014] Compared with the prior art, the utility model provides a stirring device for continuous powder mixing, which has the following beneficial effects:

[0015] 1. The continuous powder mixing stirring device, through the stirring mechanism, when the first motor rotates, drives the symmetrical spiral stirring blades to rotate at high speed through the stirring shaft, so that the powder in the stirring tank can be concentrated and pushed to the middle of the stirring tank for mixing. Moreover, due to the inclined design of the stirring tank, it can further ensure that the entire powder can be stirred around the stirring tank and will not stick to the inner wall, so as to achieve the purpose of good and sufficient powder mixing.

[0016] 2. The continuous powder mixing stirring device has a swing mechanism, and the second motor is started to drive the power gear to rotate, and the rotating power gear drives the half gear to rotate. When the half gear teeth and the power gear are meshed, the stirring tank is accelerated, and further under the action of centrifugal force, the powder moves to the upwardly tilted part of the inclined stirring tank. When the half gear and the power gear are not meshed, the rotation speed of the stirring tank is reduced due to natural inertia, and the centrifugal force is weakened, so that the stirring tank moves slowly downward from the upwardly tilted part of the stirring tank, ensuring that the powder can be fully moved and stirred in the stirring tank, and further achieving the purpose of fully and well mixing the powder.

Because the stirring tank 41 is tilted, it can further ensure that the entire powder can be stirred around the stirring tank 41 and will not stick to the inner wall, so as to achieve the purpose of good and sufficient powder mixing.

When the teeth of the half gear 35 and the power gear 36 are meshed, the mixing tank 41 is accelerated, and further under the action of centrifugal force, the powder moves toward the upwardly tilted part of the tilted mixing tank 41. When the half gear 35 and the power gear 36 are not meshed, the rotation speed of the mixing tank 41 is reduced due to natural inertia, and the centrifugal force is weakened, so that the mixing tank 41 slowly moves downward from the upwardly tilted part of the mixing tank 41, ensuring that the powder can be fully moved and stirred in the mixing tank 41, and further achieving the purpose of fully and well mixing the powder.

Moreover, because of the inclined design of the stirring tank 41, it can further ensure that the entire powder can be stirred around the stirring tank 41 and will not stick to the inner wall, thereby achieving the purpose of good and sufficient powder mixing.

[0039] The second motor 39 starts to drive the power gear 36 to rotate, and the rotating power gear 36 drives the half gear 35 to rotate. When the teeth of the half gear 35 and the power gear 36 are meshed, the mixing tank 41 is accelerated, and further under the action of centrifugal force, the powder moves toward the upwardly tilted part of the tilted mixing tank 41. When the half gear 35 and the power gear 36 are not meshed, the rotation speed of the mixing tank 41 decreases due to natural inertia and the centrifugal force is weakened, so that the mixing tank 41 slowly moves downward from the upwardly tilted part of the mixing tank 41, ensuring that the powder can be fully moved and stirred in the mixing tank 41, and further achieving the purpose of fully and well mixing the powder.
