[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following combination Figure 1-Figure 3 The present invention describes a cyclone barrel and a cyclone separator.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, in an embodiment of the present invention, the cyclone cylinder includes: a cylinder body 10, a wear-resistant layer 30 and a fire-resistant layer 40. The cylinder body 10 includes a main body portion 11 and a cyclone portion 12. The fire-resistant layer 40 is arranged between the wear-resistant layer 30 and the inner wall of the cyclone portion 12. The wear-resistant layer 30 includes multiple support components, each of which includes: a support rod 31 and a ceramic sheet 32. A metal sheet is pre-embedded on one side of the surface of the ceramic sheet 32. The two ends of the support rod 31 are respectively welded to the metal sheet and the inner wall 121 of the cyclone portion 12. Multiple ceramic sheets 32 are spliced ​​to form the wear-resistant layer 30.

[0025] Specifically, in this embodiment, the cylinder body 10 includes a main body portion 11 and a cyclone portion 12. Since the cyclone portion 12 has to withstand particle impact, friction and gas erosion, the wear-resistant layer 30 is only provided on the cyclone portion 12 to reduce manufacturing costs.

[0026] In this embodiment, the wear-resistant layer 30 is formed by splicing together a plurality of support components. Each support component includes: a support rod 31 and a ceramic sheet 32. The ceramic sheet 32 ​​is a wear-resistant ceramic sheet 32. When fired, a metal sheet is fired on one side of the ceramic sheet 32. In this embodiment, the support rod 31 is a metal rod, and the two ends of the support rod 31 are respectively connected to the metal sheet and the inner wall 121 of the cyclone part 12 by welding to improve the firmness of the wear-resistant layer 30 after it is set, and to prevent the ceramic sheet 32 ​​from falling under the impact of particles. The refractory layer 40 is arranged between the ceramic sheet 32 ​​and the inner wall 121 of the cyclone part 12. The wear-resistant layer 30 formed by splicing together a plurality of ceramic sheets 32 can utilize the wear-resistant performance of the ceramic sheet 32 ​​to protect the refractory layer 40.

[0027] Furthermore, by sintering a metal sheet on one side of the ceramic sheet 32, the ceramic sheet 32 ​​can be directly welded to the support rod 31 without having to drill holes in the ceramic sheet 32 ​​for connection. This improves the strength and impact resistance of the ceramic sheet 32, thereby enhancing the protection of the refractory layer 40. Furthermore, by welding at both ends, if a ceramic sheet 32 ​​is damaged, it can be directly cut off from the support rod 31 and replaced, reducing the maintenance difficulty of the wear-resistant layer 30 and facilitating repairs.

[0028] The plurality of ceramic sheets 32 are spliced ​​in sequence to form a cylindrical structure. In the embodiment of the present invention, the plurality of ceramic sheets 32 can be spliced ​​into various shapes such as a cylinder and a cone to match the shape of the inner wall 121 of the cyclone portion 12 .

[0029] The cyclone barrel provided by the embodiment of the present invention improves the impact resistance and wear resistance of the cyclone part by splicing multiple ceramic sheets to form a wear-resistant layer, thereby protecting the refractory layer and extending the service life of the refractory layer; by firing metal sheets on one side surface of the ceramic sheets, the ceramic sheets can be welded to the support rods, avoiding the need to open holes in the ceramic sheets, improving the impact resistance of the ceramic sheets, and thus extending the service life of the cyclone barrel.

[0030] like Figure 3 As shown, in the embodiment of the present invention, a first interface and / or a second interface are respectively provided on two opposite sides of each ceramic sheet 32 ​​, and adjacent ceramic sheets 32 are overlapped via the first interface and the second interface.

[0031] Specifically, during splicing, the first ceramic piece 32 is provided with a first interface only at one end, and the last ceramic piece 32 is provided with a second interface only at one end. As for the other ceramic pieces 32 located in the middle part during splicing, each ceramic piece 32 has a first interface and a second interface at both ends, so that multiple ceramic pieces 32 are spliced ​​into a whole by overlapping the first interface and the second interface.

[0032] The cyclone cylinder provided by the embodiment of the present invention has multiple ceramic sheets overlapped with each other through the first interface and the second interface, avoiding gaps between two adjacent ceramic sheets, improving the impact resistance and wear resistance of the wear-resistant layer, and thus providing good protection for the refractory layer.

[0033] like Figure 3 As shown, in one embodiment of the present invention, a first notch 321 is provided on the surface of the first side of the ceramic sheet 32 ​​facing the inner wall 121 of the cyclone portion 12, and a second notch 322 is provided on the surface of the second side of the ceramic sheet 32 ​​facing away from the inner wall of the cyclone portion 12, wherein the first side is opposite to the second side.

[0034] Specifically, in this embodiment, during splicing, except for the first and last ceramic pieces 32 which are only provided with the first notch 321 or the second notch 322 on one side, the remaining ceramic pieces 32 are respectively provided with the first notch 321 and the second notch 322 on their opposite sides, wherein the first notch 321 and the second notch 322 are provided in opposite directions, that is, one notch faces the inner wall 121 of the cyclone part 12, and the other notch faces away from the inner wall 121 of the cyclone part 12.

[0035] Alternatively, in another embodiment of the present invention, when splicing, except for the first and last ceramic sheets 32 having only one first or second bevel on one side, the remaining ceramic sheets 32 each have a first bevel and a second bevel on opposite sides thereof, with the first and second bevels having matching gradients. In this embodiment, the bevel is a slope.

[0036] In the embodiment of the present invention, the ceramic sheet 32 ​​can have various shapes, such as a rectangle or a regular hexagon. When the ceramic sheet 32 ​​is rectangular, interfaces can be provided on all four sides of the ceramic sheet 32, such as a first interface and a second interface respectively provided on one pair of opposing sides, and a first interface and a second interface respectively provided on another pair of opposing sides. In this way, when multiple ceramic sheets 32 are spliced ​​together, in addition to being able to be spliced ​​together in sequence along the circumferential direction of the cyclone portion 12, they can also be spliced ​​together in sequence along the longitudinal direction of the cyclone portion 12. This ensures that when multiple ceramic sheets 32 are spliced ​​together, there is no gap between any two ceramic sheets 32 in any direction, thereby improving the impact resistance and wear resistance of the wear-resistant layer 30.

[0037] When the shape of the ceramic sheet 32 ​​is a regular hexagon, a first interface and a second interface can be respectively set on each pair of opposite sides, so that multiple ceramic sheets 32 can be overlapped into a whole through overlapping in multiple directions, so that when multiple ceramic sheets 32 are spliced, there is no gap between two ceramic sheets 32 in any direction, so as to improve the impact resistance and wear resistance of the wear-resistant layer 30.

[0038] like Figure 2 As shown, in an embodiment of the present invention, the fire-resistant layer 40 includes: a lining plate and a casting layer. The lining plate is in contact with the inner wall 121 of the cyclone portion 12 , and the casting layer is located between the lining plate and the wear-resistant layer 30 .

[0039] Specifically, in this embodiment, the casting layer is a low-temperature wear-resistant casting material, which, after being cast between the liner and the wear-resistant layer 30 and hardened, will play a secondary reinforcement role in the cyclone part 12 to improve the performance of the refractory layer 40.

[0040] Furthermore, in an embodiment of the present invention, the thickness of the lining plate is 70 mm, and the thickness of the casting layer is 110 mm. By increasing the thickness of the casting layer, the impact resistance of the refractory layer 40 is also improved, thereby increasing the service life of the refractory layer 40.

[0041] Optionally, in an embodiment of the present invention, the lining plate is a ceramic fiber backing plate, which has a heat-insulating effect and can prevent heat loss in the cyclone barrel.

[0042] The present invention also provides a cyclone separator, comprising an inner cylinder 20, an ash hopper and a cyclone body. The two ends of the cyclone body are respectively connected to the inner cylinder 20 and the ash hopper, the cyclone body is provided with an air inlet, and the inner cylinder 20 is provided with an air outlet.

[0043] Specifically, the cyclone barrel comprises a barrel body 10, a wear-resistant layer 30, and a fire-resistant layer 40. The barrel body 10 comprises a main body portion 11 and a cyclone portion 12. The inner barrel 20 is connected to the cyclone portion 12, and the ash hopper is connected to the barrel body 11. The cyclone portion 12 has an air inlet, and the inner barrel 20 has an air outlet. Dust-laden gas enters the barrel body 10 through the air inlet and spirals downward along the inner wall of the barrel body 10. Centrifugal force throws dust toward the inner wall of the barrel body 10, where it falls into the ash hopper under the influence of gravity. The purified gas is discharged through the air outlet of the inner barrel 20.

[0044] Furthermore, the refractory layer 40 is disposed between the wear-resistant layer 30 and the inner wall of the cyclone portion 12. The wear-resistant layer 30 includes multiple support assemblies, each of which includes a support rod 31 and a ceramic sheet 32. A metal sheet is pre-embedded on one side of the ceramic sheet 32. The ends of the support rod 31 are welded to the ceramic sheet 32 ​​and the inner wall 121 of the cyclone portion 12, respectively. Multiple ceramic sheets 32 are spliced ​​together to form the wear-resistant layer 30.

[0045] In this embodiment, the wear-resistant layer 30 is formed by splicing together a plurality of support components. Each support component includes: a support rod 31 and a ceramic sheet 32. The ceramic sheet 32 ​​is a wear-resistant ceramic sheet 32. When fired, a metal sheet is fired on one side of the ceramic sheet 32. In this embodiment, the support rod 31 is a metal rod, and the two ends of the support rod 31 are respectively connected to the metal sheet and the inner wall 121 of the cyclone part 12 by welding to improve the firmness of the wear-resistant layer 30 after it is set, and to prevent the ceramic sheet 32 ​​from falling under the impact of particles. The refractory layer 40 is arranged between the ceramic sheet 32 ​​and the inner wall 121 of the cyclone part 12. The wear-resistant layer 30 formed by splicing together a plurality of ceramic sheets 32 can utilize the wear-resistant performance of the ceramic sheet 32 ​​to protect the refractory layer 40.

[0046] Furthermore, by sintering a metal sheet on one side of the ceramic sheet 32, the ceramic sheet 32 ​​can be directly welded to the support rod 31 without having to drill holes in the ceramic sheet 32 ​​for connection. This improves the strength and impact resistance of the ceramic sheet 32, thereby enhancing the protection of the refractory layer 40. Furthermore, by welding at both ends, if a ceramic sheet 32 ​​is damaged, it can be directly cut off from the support rod 31 and replaced, reducing the maintenance difficulty of the wear-resistant layer 30 and facilitating repairs.

[0047] The plurality of ceramic sheets 32 are spliced ​​in sequence to form a cylindrical structure. In the embodiment of the present invention, the plurality of ceramic sheets 32 can be spliced ​​into various shapes such as a cylinder and a cone to match the shape of the inner wall 121 of the cyclone portion 12 .

[0048] The cyclone separator provided by the embodiment of the present invention improves the impact resistance and wear resistance of the cyclone part by providing a cyclone barrel, thereby protecting the refractory layer, extending the service life of the refractory layer, and further extending the service life of the cyclone separator.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
