Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of magnetic powder processing equipment, especially a magnetic powder winnowing equipment with controllable air volume. BACKGROUND

[0002] Magnetic powder generally refers to tiny particles with magnetic properties that can be magnetized and subjected to magnetic force in a magnetic field. Magnetic powder plays an important role in various industrial applications, such as the manufacture of magnetic materials, magnetic recording media, etc. Winnowing is a technique based on the density and volume difference of materials to separate them. During the winnowing process, by controlling the flow of gas, materials with different densities and volumes can be separated.

[0003] At present, when magnetic powder is screened by winnowing, it is usually lifted once for winnowing by relying on the gravity of the magnetic powder. The number of times the magnetic powder is lifted and the dispersion effect are limited, which cannot fully contact with the airflow, resulting in incomplete separation, and thus repeated processing is required, increasing production energy consumption and cost. Therefore, we propose a magnetic powder winnowing equipment with controllable air volume to solve the above problems. SUMMARY

[0004] The utility model aims at providing a magnetic powder winnowing equipment with controllable air volume to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A magnetic powder winnowing equipment with controllable air volume, comprising a support frame, the outer surface of the support frame is inlaid with a plurality of first bearings, the inner ring of every two first bearings is fixedly connected with a rotating rod, the outer surface of each rotating rod is fixedly connected with two transmission wheels, the outer surface of the support frame is fixedly connected with a blowing mechanism, the upper surface of the support frame is provided with a roller, the outer surface of the support frame is fixedly connected with a first motor, the output end of the first motor is connected with the outer surface of one rotating rod, the inner side wall of the roller is fixedly connected with a first spiral blade, the inner side wall of the roller is fixedly connected with a plurality of baffles, the outer surface of the support frame is fixedly connected with a feeding mechanism, and the outer surface of the support frame is fixedly connected with a sorting box.

[0007] In further embodiments, the blowing mechanism includes an air inlet shell, and the inner side wall of the air inlet shell is fixedly connected with a speed-regulating fan.

[0008] In further embodiments, the inner side wall of the air inlet shell is fixedly connected with an air deflector, and the inner side wall of the air inlet shell is fixedly connected with a filter screen.

[0009] In further embodiments, the feeding mechanism includes a feeding hopper, and the inner top wall of the feeding hopper is inlaid with a second bearing.

[0010] In a further embodiment, a connecting rod is fixedly connected to the inner ring of the second bearing, and a second helical blade is fixedly connected to the outer surface of the connecting rod.

[0011] In a further embodiment, a second motor is fixedly connected to the upper surface of the feeding funnel, and the output end of the second motor is connected to the upper surface of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a feeding mechanism to evenly feed magnetic powder into the drum. A first motor drives the rotating rod, transmission wheel, and drum to rotate. With the help of the first spiral blades and baffles on the inner side wall of the drum, the magnetic powder can be continuously moved as the drum rotates. The magnetic powder is also lifted and scattered by the baffles, realizing multiple lifting of the magnetic powder and allowing it to fully contact the airflow. This improves the thoroughness of magnetic powder sorting by mass and volume, and enhances the sorting effect. Attached Figure Description

Two transmission wheels 4 are fixedly connected to the outer surface of each rotating rod 3. A blower mechanism 5 is fixedly connected to the outer surface of the support frame 1. A roller 6 is provided on the upper surface of the support frame 1. A first motor 10 is fixedly connected to the outer surface of the support frame 1.

The roller 6 is fixedly connected with a first spiral blade 7, and multiple baffles 8 are fixedly connected to the inner side wall of the roller 6. A feeding mechanism 9 is fixedly connected to the outer surface of the support frame 1, and a sorting box 11 is fixedly connected to the outer surface of the support frame 1. The inner side wall of the roller 6 is provided with an anti-stick layer. By rotating the roller 6, the first spiral blade 7 and the baffles 8 can be driven to rotate. The first spiral blade 7 can drive the magnetic powder to move towards the sorting box 11, while the baffles 8 can drive the magnetic powder to rise and be lifted again, thereby realizing the multiple lifting of the magnetic powder, so that it can fully contact the airflow and improve the sorting effect.

[0023] The blower mechanism 5 includes an air inlet housing 501, a speed-regulating fan 502 fixedly connected to the inner wall of the air inlet housing 501, an air guide plate 503 fixedly connected to the inner wall of the air inlet housing 501, and a filter screen 504 fixedly connected to the inner wall of the air inlet housing 501. By controlling the speed of the speed-regulating fan 502, the air volume can be flexibly adjusted according to the characteristics of the magnetic powder. By setting the air guide plate 503, the air can be accurately blown to the roller 6.

[0024] The feeding mechanism 9 includes a feeding funnel 901. A second bearing 902 is embedded in the inner top wall of the feeding funnel 901. A connecting rod 904 is fixedly connected to the inner ring of the second bearing 902. A second spiral blade 905 is fixedly connected to the outer surface of the connecting rod 904.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the second motor 903 drives the connecting rod 904 and the second spiral blade 905 to rotate, which can evenly transport the magnetic powder into the drum 6. The first motor 10 is turned on to drive the rotating rod 3 and the transmission wheel 4 to rotate. The transmission wheel 4 drives the drum 6 to rotate. The speed-regulating fan 502 is turned on to drive the air flow and blow the air into the drum 6 through the air guide plate 503. When the drum 6 rotates, the first spiral blade 7 will drive the magnetic powder to move. When the magnetic powder moves to the baffle 8, it will be lifted by the baffle 8 and then sprinkled again, thereby realizing the multiple lifting and air separation of the magnetic powder. Finally, the magnetic powder is carried into different spaces of the sorting box 11 by the wind according to its own mass and volume.
