[0040] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0041] The embodiment of the present application provides a hot air circulation mechanism of a heating centrifugal machine, such as Figure 1 and 2As shown, the heating centrifuge comprises a base 1, a casing 2 mounted on the base, and a cover 3 covering the casing, a heating furnace 4 is mounted inside the casing, the inner surface of the casing 2 is provided with a heat preservation layer, the heat preservation layer wraps the heating furnace, the heat preservation layer is piled up by fire bricks, and the inner surface of the cover 3 is also provided with a heat preservation layer.

The lower end of the liquid blocking cylinder 7 is a free end, the liquid blocking cylinder 7 extends into the liquid collecting groove and a gap is left between the two to form a first air outlet 100, a second air outlet 200 is provided on the liquid blocking cylinder close to the opening of the drum, and a third air outlet 300 is provided at the bottom of the drum.

[0043] In this embodiment, the circulating fan is mounted above the drum, the gap between the liquid blocking cylinder on the outer side of the drum and the liquid collecting groove forms the first air outlet, the second air outlet is provided on the liquid blocking cylinder, and the third air outlet is provided inside the drum. In the process of centrifugal separation, the rotation of the circulating fan drives the heat generated by the heating furnace on the wall surface of the casing to form hot air, the hot air enters the inside of the drum from the second air outlet on the liquid blocking cylinder, the hot air exchanges heat in the inside of the drum and then flows out through the third air outlet at the bottom of the drum, and then flows out to the outside of the drum from the gap between the liquid collecting groove and the liquid blocking cylinder, that is, the first air outlet, enters the space between the drum and the casing, the cold air after heat exchange exchanges heat with the heat generated by the heating furnace on the wall surface of the casing again, the hot air formed after heat exchange enters the inside of the drum through the second air outlet above the liquid blocking cylinder again, and so on, thereby forming a gas circulation loop, as shown by the arrows. Figure 1 As the heat exchange in the inside of the drum is continuously carried out, the material in the center is fully heated, the heating time is shortened, and the centrifugal efficiency is improved.

[0044] In this embodiment, the drum 5 is provided with a material frame 11, a plurality of material frames 12 are mounted in the material frame 11, and the plurality of material frames 12 are distributed in a fan shape along the inner wall surface of the drum 5, as shown by the arrows. Figure 3 and 4As shown, the material frame 11 includes a top connecting ring 110, a bottom connecting ring 111, a center connecting column 112, and a plurality of longitudinal partitions 113 connected with the top connecting ring 110, the bottom connecting ring 111 and the center connecting column 112 respectively, which divide the internal space of the material frame 11 into a plurality of accommodation chambers 114; a plurality of material frames 12 are placed in the accommodation chambers 114 in sequence. The top connecting ring 110 of the material frame 11 is overlapped on the opening of the rotating drum 5, and a plurality of limiting columns 115 and limiting grooves 116 matched with each other are arranged at the overlapping part, and the limiting column 115 is located in the limiting groove 116; in this embodiment, the limiting column and the limiting groove are arranged between the rotating drum and the material frame, and the limiting column is located in the limiting groove, and a certain gap is left between the limiting column and the limiting groove, which on the one hand facilitates the taking and placing of the material frame from the rotating drum, and on the other hand can make the material frame only slide a small amplitude in the rotating drum under the action of the centrifugal force, thereby ensuring the stability of the centrifugation. There are two ways to arrange the limiting column and the limiting groove, one is that the limiting column is arranged on the opening of the rotating drum, and the limiting groove is arranged on the top connecting ring; the other is that the limiting column is arranged on the top connecting ring, and the limiting groove is arranged on the opening of the rotating drum. The material frame and the rotating drum in this embodiment can also be connected by clamping (not shown in the figure, consistent with the prior art), such as arranging a buckle on the top connecting ring of the material frame and arranging a clamping groove on the opening of the rotating drum, and the buckle is clamped in the clamping groove, and when taking out, only an outward force is needed to make the buckle separate from the clamping groove, so as to realize the separation of the two. The mode of this embodiment is not limited to this, and other modes that can fix the material frame and the rotating drum are within the scope shown in this embodiment.

[0045] The cross-sectional shape of the accommodation chamber 114 is a sector, and after the material frame 12 is placed in the accommodation chamber 114, a gap is left between the material frame 12 and the inner wall of the rotating drum 5. The gap position can facilitate the centrifugal separation process, and a plurality of arrayed filter holes are arranged on the side wall of the material frame 12 facing the inner wall of the rotating drum 5, and a plurality of filter holes are also arranged on the side wall of the rotating drum. When the material (such as high-aluminum coal gangue fly ash) placed in the material frame is heated to about 700°C in the heating furnace, the material melts, and the liquid material flows out of the filter hole of the material frame under the action of the centrifugal force and then separates through the filter hole on the inner wall of the rotating drum, thereby facilitating liquid separation. The gap left refers to that a plurality of convex strips 120 are arranged on the side wall of the material frame 12 facing the inner wall of the rotating drum 5, such as Figure 5As shown, multiple protrusions are attached to the inner wall of the drum. In this embodiment, the protrusions can also be set on the inner wall of the drum, so that they are attached to the material frame. The height of the protrusions can be determined according to the gap between the material frame and the drum under actual use. The direction of the protrusions can be set along the axial direction of the drum or along the radial direction of the drum. In order to achieve the guiding and positioning function of the material frame and the drum, they are generally set to be arranged in the axial direction. In order to fix the material frame and the drum, a guide groove that cooperates with the protrusions can be set, and the protrusions are located in the guide groove (not shown in the figure, consistent with the prior art).

[0046] In this embodiment, the central connecting column 112 of the material frame 11 is also provided with ventilation holes 1120, such as... Figure 4 As shown, the ventilation hole 1120 connects from the top to the bottom of the central connecting column 112. The ventilation hole is also connected to the third air outlet at the bottom of the drum, forming a gas circulation loop together with the first air outlet, the second air outlet and the third air outlet. This arrangement is more conducive to the hot air and the material making full contact, thus improving the centrifugation efficiency.

[0047] In this embodiment, the cover 3 is provided with a discharge port 13, such as Figure 1 As shown, a foldable discharge cover is installed on the discharge port (shown in the figure, consistent with the prior art). The position of the discharge port 13 on the cover 3 corresponds to that of the material frame 12, and is used for placing and removing the material frame. A drain port 14 is provided at the bottom of the liquid collection tank 10, and the drain port 14 is connected to the bottom of the casing 2.

[0048] In this embodiment, the transmission main shaft of the transmission mechanism is fixedly connected to the bottom of the drum and further extends into the central connecting column of the material frame for fixed connection. Specifically, a boss 50 is provided on the outer bottom surface of the drum 5. Figure 6 As shown, a bearing housing is installed on the boss, and the drive shaft is located inside the bearing housing. One end first extends into the drum and is fixedly connected to it, and then extends further into the central connecting column of the material frame to achieve a fixed connection with the material frame. The other end of the shaft is connected to the drive motor. The inner bottom surface of the drum is a conical surface with a higher center and lower edges. The conical surface design can effectively collect liquid materials and effectively filter them out through the filter holes on the inner wall of the drum.

[0049] In this embodiment, handles 15 are installed on the material frame, multiple material boxes, and the unloading cover. The installation position of each handle is not specifically limited in this embodiment. As long as it enables convenient access to the material frame and material boxes, and allows the unloading cover to be opened and closed, it is within the protection scope of this embodiment.
