[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0018] Embodiment 1, in combination with the drawings Figure 1 A device for automatically cleaning the magnetic core of the powder magnetic removing machine according to the present application, comprising a beam sound conduction cylinder 1 and a titanium alloy acoustic wave generator 2, wherein the titanium alloy acoustic wave generator 2 is used to make the high-energy titanium alloy diaphragm vibrate to emit acoustic waves of a certain frequency and sound pressure level by using compressed air.

[0019] The beam sound conduction cylinder 1 is in the shape of a horn, and the titanium alloy acoustic wave generator 2 is installed at the end of the beam sound conduction cylinder 1 with a smaller opening diameter.

[0020] The other end of the beam sound conduction cylinder 1 is fixedly connected with a connecting flange 3 outside.

[0021] The connecting flange 3 is fixedly connected with a sealing protective cover 4 near the titanium alloy acoustic wave generator 2, the beam sound conduction cylinder 1 and the titanium alloy acoustic wave generator 2 are located inside the sealing protective cover 4, and the gas inlet interface 5 of the titanium alloy acoustic wave generator 2 extends out of the sealing protective cover 4 to the outside and is sealingly connected with the sealing protective cover 4.

[0022] The connecting flange 3 is provided with a plurality of connecting holes 6 along the circumference for connecting with the on-site conveying pipeline.

[0023] The sound beam conducting cylinder 1, the connecting flange 3 and the sealing protective cover 4 are made of metal materials.

[0024] The sound beam conducting cylinder 1 and the connecting flange 3 are fixedly connected by welding, and the connecting flange 3 and the sealing protective cover 4 are fixedly connected by welding.

[0025] The device for automatically cleaning the magnetic core of the powder removing machine adopts input of 0.5-0.8mpa gas through the gas inlet interface 5 to the titanium alloy sound wave generator 2 to emit sound with appropriate frequency and appropriate energy without the need of electric energy.

[0026] In particular, the sound beam conducting cylinder 1, the connecting flange 3 and the sealing protective cover 4 can also be made of non-metal materials.

[0027] When the device is supplied with gas, the titanium alloy sound wave generator 2 emits sound, and the emitted sound is directed and concentrated by the sound beam conducting cylinder 1 so as to be able to act on the surface of the magnetic core in a directional manner. The air vibration caused by the sound wave can transmit kinetic energy to the object that hinders the propagation of the sound wave, so as to make the residual material on the surface of the magnetic core fall off, thereby achieving the purpose of cleaning.

[0028] Working principle:

[0029] The sound wave energy is concentrated on the material adsorbed on the medium net, mainly through the following three forms:

[0030] 1) Sound pressure shear: when the sound wave energy is transmitted to the medium net acting surface, the vibration of the sound beam particle will transmit kinetic energy to the object that hinders the propagation of the beam, and due to the different density and mass of the dust and the medium net, the response speed of the dust after absorbing the sound wave energy is also different, thereby generating a speed difference on the surface of the dust and the medium net. The shearing action makes the material separate from the surface of the magnetic core;

[0031] 2) Fatigue effect: due to the repeated action of sound wave oscillation, the load applied to the dust / magnetic material is cyclically changed in tension and compression, and when the number of cyclic stress cycles N reaches a certain value, the combination of the magnetic material and the medium net is gradually destroyed due to fatigue;

[0032] 3) Frequency response: the material adsorbed on the medium net is in a regular or irregular motion state, in addition to the flow caused by the action of the gas flow, its own mass is also different, and it is in a self-vibration state of different frequencies; after the sound wave generated by the sound wave generator is fed into the space, the frequency of the sound wave and the self-vibration frequency of the material particles are coupled and responded, the activity of the particle's own motion is excited, the particle's own motion is intensified, so that it can escape from the adsorption stress and become a free moving body, and finally it is taken away by gravity.

In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In addition, if the terms "horizontal", "vertical", "overhanging" and the like are not required to be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0035] In the description of the embodiments of the utility model, "a plurality of" represents at least 2.

[0036] In the description of the embodiments of the utility model, it also needs to be explained that, unless otherwise explicitly specified and limited, if the terms "set", "install", "connect", "connect" are broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements.
