[0029] Compared with related technologies, the three-stage cyclone activation device for slag and soil micropowder provided by the present invention has the following beneficial effects: This invention provides a three-stage cyclone activation device for slag and soil powder. Utilizing a three-stage cyclone system, the activation of slag and soil powder is divided into three steps: mechanical activation, thermal activation, and alkaline activation. Compared with traditional activation methods, this device has advantages such as high spontaneity and high efficiency.

[0030] Second Embodiment Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application which provides a three-stage cyclone activation device for slag powder, the second embodiment of this application proposes another three-stage cyclone activation device for slag powder. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0031] Specifically, the difference in the second embodiment of this application regarding the three-stage cyclone activation device for slag powder is that, in the three-stage cyclone activation device and its method of use for slag powder, a fixing plate 30 is fixedly installed on both sides of the top of the cyclone separator 5, a horizontal plate 31 is fixedly installed on the top of the fixing plate 30, a driving component 32 is fixedly installed in the middle of the top of the horizontal plate 31, a drive gear 33 is fixedly connected to the bottom end of the output shaft of the driving component 32, and extrusion protrusions 34 are fixedly installed around the outer surface of the pipe of the air outlet 5 22.

[0032] A driven gear 35 is rotatably mounted in the middle of the top of the cyclone separator 5. A connecting hole 36 is opened in the middle of the top of the driven gear 35. An elastic plate 37 is provided on one side of the inner wall surface of the connecting hole 36.

[0033] Air outlet 1 (7), air outlet 2 (10), air outlet 3 (14), air outlet 4 (17), and air outlet 5 (22) are all connected to a pipeline for air diversion. Filter plates are installed at the bottom of the pipeline for filtering particulate matter.

[0034] The elastic plate 37 adopts a spring plate structure. When the elastic plate 37 is attached to the pipe surface, it already has a slight deformation effect and exerts a squeezing force on the pipe. The elastic plate 37 becomes stronger with the squeezing deformation effect of the squeezing protrusion 34. When the squeezing protrusion 34 does not affect the elastic plate 37, the restoring elastic force of the elastic plate 37 hits the pipe surface.

[0035] The drive unit 32 uses a servo motor device.

[0036] The working principle of the three-stage cyclone activation device for slag powder provided by this invention is as follows: During operation, the output shaft of the drive component 32 first rotates, driving the drive gear 33 to rotate. The drive gear 33 rotates and meshes with the driven gear 35 to rotate. The driven gear 35 rotates, driving the elastic plate 37 to rotate. The elastic plate 37 is deformed by the pressure protrusion 34. When the elastic plate 37 rotates and is freed from the pressure of the pressure protrusion 34, the elastic plate 37 returns to its original shape. The elastic plate 37 strikes the surface of the pipe connected to the air outlet, causing the pipe to vibrate and shaking off the particles accumulated on the surface of the filter plate.

[0037] Compared with related technologies, the three-stage cyclone activation device for slag and soil micropowder provided by the present invention has the following beneficial effects: This invention provides a three-stage cyclone activation device for slag micro powder. The drive component 32 drives the output shaft to rotate the active gear 33 and mesh with the driven gear 35. The rotation of the driven gear 35 drives the elastic plate 37 to rotate. The elastic plate 37 is deformed by the extrusion protrusion 34 and then recovers its original shape when it is no longer being extruded by the extrusion protrusion 34. The elastic plate 37 strikes the surface of the air outlet pipe to generate vibration, which shakes off the particles blocking the surface of the filter plate at the bottom of the pipe, avoiding particle blockage of the filter plate and maintaining the air outlet efficiency.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
