For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0059] See also Figure 1 and Figure 2 The embodiment of the present invention provides a liner 1000, which is installed on the inner wall of a cylinder (not shown in the figure) to protect the inner wall of the cylinder from being worn or scratched by foreign matter (such as metal particles). The cylinder can be a mixing cylinder of a coulter dryer, a grinding cylinder of a grinder, or a cylinder of other functional cylinders, which is not limited to this.

[0060] For details, please combine Figures 1 to 3In one embodiment of the present invention, the liner 1000 includes at least one liner assembly 1, and each liner assembly 1 includes at least two arc-shaped liner plates 10 sequentially spliced ​​along the circumference of the cylinder. That is, each liner assembly 1 includes at least two arc-shaped liner plates 10 sequentially spliced ​​along the circumference of the cylinder to form a ring, and the liner 1000 is assembled from at least one ring of arc-shaped liner plates 10.

[0061] Among them, Figures 1 to 3 As shown, along the circumference of the cylinder, of each two adjacent lining plates 10, at least one lining plate 10 is provided with a connection structure 100, and the connection structure 100 is used to detachably install the lining plate 10 on the inner circumferential wall of the cylinder, and at least one lining plate 10 is provided with a tongue 200 on the side adjacent to the other lining plate 10, and the tongue 200 is provided on the side facing the cylinder, and the corresponding side of the other lining plate 10 is provided with a tenon 300, and the tenon 300 corresponds to the tongue 200 one by one. Figure 1 and Figure 3 As shown, when two adjacent lining plates 10 are spliced, one of the lining plates 10 (for example Figure 3 The tenon 300 of the first lining plate 11 is received in another lining plate 10 (eg Figure 3 The third lining plate 13 shown in the figure is in the corresponding tenon groove 200 and is clamped between the inner circumferential wall of the cylinder and the portion of the lining plate 10 with the tenon groove 200 corresponding to the tenon groove 200, thereby forming a mortise and tenon structure, so that the portion of the lining plate 10 with the tenon groove 200 corresponding to the tenon groove 200 can fit the tenon 300 of the adjacent lining plate 10 to the inner circumferential wall of the cylinder.

[0062] It is easy to understand that, in each of the two adjacent lining plates 10, at least one lining plate 10 is provided with a connection structure 100 and a mortise and tenon structure is formed between the two lining plates 10. When both lining plates 10 are provided with a connection structure 100, each lining plate 10 can be detachably mounted on the inner peripheral wall of the cylinder through the connection structure 100. On the contrary, when only one lining plate 10 is provided with a connection structure 100, the lining plate 10 provided with the connection structure 100 can be detachably mounted on the inner peripheral wall of the cylinder through the connection structure 100, while the other lining plate 10 can be detachably mounted on the inner peripheral wall of the cylinder through the fixing effect of the mortise and tenon structure between the two lining plates 10. In other words, based on the fixing effect of the connection structure 100 and the mortise and tenon structure, at least two arc-shaped lining plates 10 included in each lining plate assembly 1 can be detachably mounted on the inner peripheral wall of the cylinder. In this way, the liner 1000 provided in the embodiment of the present invention is composed of at least two arc-shaped lining plates 10, and can be detachably installed on the inner circumferential wall of the cylinder. It can not only protect the inner circumferential wall of the cylinder and prevent the inner circumferential wall of the cylinder from being worn or scratched by foreign objects, but also the lining plate 10 can be removed and replaced when any lining plate 10 is worn, thereby ensuring that the cylinder can be used normally.

[0063] Among them, each lining plate 10 can be, but is not limited to, made of metal material and made through a rolling process, preferably a metal material with good thermal conductivity, wear resistance and high temperature resistance, so that the lining 1000 is suitable for different application scenarios. Furthermore, the surface of each lining plate 10 facing away from the cylinder can be coated with a wear-resistant coating to improve the wear resistance of the lining plate 10. In addition, each lining plate 10 can be tightly fitted to the inner circumferential wall of the cylinder under the fixing action of the connection structure 100 and / or the mortise and tenon structure, so that the entire lining 1000 is tightly attached to the inner circumferential wall of the cylinder without any gap, so that there is a good thermal conductivity effect between the lining 1000 and the cylinder.

[0064] Preferably, please combine Figures 4 to 13 In one embodiment of the present invention, the tenon 300 of any lining plate 10 is a plate-like structure, and a first gap is left between the tenon 300 and the corresponding tenon groove 200 at least in the circumferential direction of the cylinder body and the opposite side walls. It can be understood that by leaving the first gap between the side wall of the tenon 300 and the side wall of the tenon groove 200, it can be used as an expansion joint to provide a deformation space, thereby preventing the lining plate 10 from being deformed by mutual squeezing at the tenon and mortise structure when it expands due to heat, thereby affecting the fixing effect of the tenon and mortise structure. Among them, the value range of the first gap is preferably 0.5mm to 1mm.

[0065] It is also preferred to combine Figure 1 and Figure 2 In one embodiment of the present invention, a second gap is left between the side of each liner 10 and the side of another adjacent liner 10. Similarly, the second gap can also be used as an expansion joint to provide deformation space, thereby preventing the liner 10 from being deformed by squeezing each other at adjacent sides when it expands due to heat. The value range of the second gap is preferably 0.2mm to 2mm. By limiting the value of the second gap to a reasonable range, not only the demand for deformation space is met, but also the gap between two adjacent liner plates 10 can be prevented from being too large, causing particles to enter the gap between the two liner plates 10.

[0066] Alternatively, if Figures 8 to 13 As shown, in one embodiment of the present invention, the tenon 300 of any liner 10 is provided with a connection structure 100. It can be understood that by providing the connection structure 100 on the tenon 300 of the liner 10, the liner 10 can not only be connected to the inner circumferential wall of the cylinder through the connection structure 100, but also can be fixedly attached to the inner circumferential wall of the cylinder based on the mortise and tenon structure between the two liner 10, which is conducive to improving the connection stability between the liner 10 and the cylinder.

[0067] Preferably, please refer to Figure 1 and Figures 8 to 13In one embodiment of the present invention, the surface of the tenon 300 of any liner 10 facing away from the cylinder does not exceed the surface of the liner 10 facing away from the cylinder, and the surface of the tenon 300 facing the cylinder and the surface of the liner 10 facing the cylinder are located on the same circumferential surface. When the tenon 300 is received in the corresponding tenon groove 200, the surfaces of the two adjacent liner 10 facing away from the cylinder are located on the same circumferential surface, so that the inner circumferential wall surface of the liner 1000 can be a smooth circumferential surface, which improves the aesthetics of the inner circumferential wall surface of the liner 1000.

[0068] Among them, Figures 4 to 13 As shown, in one embodiment, there is a height difference between the surface of the tenon 300 facing away from the cylinder and the surface of the lining plate 10 facing away from the cylinder, and a step structure is formed at the connection between the tenon 300 and the lining plate 10. In other embodiments, the surface of the tenon 300 facing away from the cylinder may be an inclined surface, and there is a first distance between the end of the inclined surface close to the side of the lining plate 10 and the inner circumferential wall of the cylinder, and there is a second distance between the end of the inclined surface away from the side of the lining plate 10 and the inner circumferential wall of the cylinder, the first distance is greater than the second distance, and the tenon 300 is a wedge-shaped structure. In other words, in the embodiment of the present invention, the tenon 300 can be either a tenon 300 of a step structure or a tenon 300 of a wedge-shaped structure. Preferably, in Figures 4 to 13 In the example, the tenon 300 is a tenon 300 of a step structure. When the tenon 300 of the step structure is received in the corresponding tenon groove 200, the portion of the lining plate 10 corresponding to the tenon groove 200 can apply a radial or substantially radial pressing force to the tenon 300 of the step structure, which is more conducive to pressing the tenons 300 of adjacent lining plates 10 tightly against the inner circumferential wall of the cylinder.

[0069] Preferably, in some embodiments of the present invention, the thickness of each lining plate 10 is in the range of 3 mm to 6 mm. By limiting the thickness of the lining plate 10 to a reasonable range, it is possible to reduce the consumables of the lining plate 10 and make the lining plate 10 have a certain flexibility so that it can be deformed adaptively according to the size of the inner circumferential wall of the cylinder, thereby improving the fit between the lining plate 10 and the inner circumferential wall of the cylinder. In addition, when the cylinder needs to work under heating conditions, the thin thickness of the lining plate 10 is also conducive to improving the heat conduction effect.

[0070] It is also preferred that in some embodiments of the present invention, the central angle corresponding to the arc surface of each liner 10 has a value range of 15 degrees to 40 degrees. By limiting the central angle corresponding to the arc surface of the liner 10, it is possible to avoid a single liner 10 being too large to be inconvenient for manufacturing and disassembly, and at the same time, the number of liner 10 included in the annular liner assembly 1 can be reduced, thereby improving the efficiency of disassembly. Among them, the central angle corresponding to the arc surface of each liner 10 can be the same angle that is divisible by 360, or it can be different angles, as long as the sum of the central angles corresponding to the arc surfaces of all the liner 10 included in the liner assembly 1 is 360 degrees.

[0071] Please refer again Figure 1 and Figure 2 In one embodiment of the present invention, the liner 1000 preferably includes at least two liner assemblies 1, and the at least two liner assemblies 1 are arranged adjacent to each other in the axial direction of the cylinder. By setting the liner 1000 to include at least two liner assemblies 1 arranged adjacent to each other in the axial direction of the cylinder, the size of each liner assembly 1 in the axial direction of the cylinder can be reduced, thereby reducing the size of each liner 10, which is conducive to reducing the difficulty of manufacturing the liner 10 and improving the efficiency of disassembly and assembly of the liner 1000.

[0072] It should be noted that, in the embodiment of the present invention, when the cylinder is provided with at least one first functional hole, at least one lining plate 10 may be provided with a second functional hole (for example, Figure 4 The second functional hole 11a of the first lining plate 11, and Figure 6 The second functional hole 11b of the first lining plate 11 shown in the figure, the second functional hole on the lining plate 10 corresponds to the first functional hole on the barrel. For example, when the barrel is a mixing barrel of a plowshare dryer, the barrel of the mixing barrel will be provided with first functional holes such as a feed port, an inlet, and a window. Correspondingly, one or more lining plates 10 of the liner 1000 will be provided with second functional holes corresponding to the feed port, the inlet, and the window. The shape of the second functional hole can be Figure 4 The circular hole shown can also be Figure 6 The square hole shown can be set according to actual needs.

[0073] It should also be noted that, in the embodiment of the present invention, the lining plate 10 may have, but is not limited to, three sides, four sides or more sides, that is, the lining plate 10 may be a lining plate 10 with a substantially triangular structure, a quadrilateral structure or a more polygonal structure, and the connection structure 100 may be, but is not limited to, a bolt connection structure or a snap connection structure, which is not limited. Figure 1 To Attachment Fig.13 , the specific structure of the liner 1000 provided in one embodiment of the present invention is further described in detail.

[0074] Please combine Figure 1 , Figures 4 to 13 In one embodiment of the present invention, each lining plate 10 is an arc-shaped lining plate 10 having four sides and a substantially quadrilateral structure. Each lining plate 10 includes a first straight side 101 and a second straight side 102, and a first curved side 103 and a second curved side 104, each straight side extends along the axial direction of the cylinder, each curved side extends along the circumferential direction of the cylinder, and the first straight side 101 of each lining plate 10 is spliced ​​with the second straight side 102 of another adjacent lining plate 10.

[0075] Specifically, Figure 1 As shown, in one embodiment of the present invention, each liner assembly 1 includes at least one first liner 11 and at least one transition liner, and the transition liner may include a second liner 12 and / or a third liner 13, which will be described in detail later. Figures 4 to 13 As shown, the first straight edge 101 and the second straight edge 102 of the first lining plate 11, and the first straight edge 101 of the transition lining plate are provided with a connection structure 100 and a tongue and tongue groove 200, the connection structure 100 and the tongue and tongue groove 200 are spaced apart along the extension direction of the first straight edge 101 of the lining plate 10, and the second straight edge 102 of the transition lining plate is provided with a tenon 300. Among them, the second straight edge 102 of another lining plate 10 spliced ​​with the first straight edge 101 of the transition lining plate is provided with a tongue and tongue groove 200, the connection structure 100 of the first straight edge 101 of the transition lining plate is received in the tongue and tongue groove 200 of the second straight edge 102 of the corresponding other lining plate 10, and the tongue and tongue 300 of the second straight edge 102 of the transition lining plate is received in the tongue and tongue groove 200 of the first straight edge 101 of the corresponding other lining plate 10.

[0076] In the present embodiment, the first straight edge 101 of each lining plate 10 is provided with a connecting structure 100, so that the lining plate 10 can be detachably installed on the inner circumferential wall of the cylinder through the connecting structure 100, which is beneficial to improve the stability of each lining plate 10 installed on the inner circumferential wall of the cylinder; furthermore, each two adjacent lining plates 10 form a mortise and tenon structure through the mortise groove 200 of the adjacent spliced ​​first straight edge 101 and the tenon 300 of the second straight edge 102, which further improves the stability of each lining plate 10 installed on the inner circumferential wall of the cylinder; in addition, the connecting structure 100 of each lining plate 10 can be accommodated in the mortise groove 200 of another adjacent lining plate 10, so that the connecting structure 100 is hidden, which is beneficial to improve the aesthetics of the lining 1000.

[0077] It should be noted that the other lining plate 10 spliced ​​with the first straight edge 101 of the transition lining plate may be the first lining plate 11, for example Figure 1 The first straight edge 101 (left side in the figure) of the second lining plate 12 is spliced ​​with the second straight edge 102 (right side in the figure) of the first lining plate 11; of course, the other lining plate 10 spliced ​​with the first straight edge 101 of the transition lining plate can also be another transition lining plate, for example Figure 1The first straight edge 101 (left side in the figure) of the third lining plate 13 is spliced ​​with the second straight edge 102 (right side in the figure) of the second lining plate 12. In addition, the tenon 300 of the second straight edge 102 of the transition lining plate can have different structural designs, so that the transition lining plate can be a transition lining plate of different types.

[0078] Specifically, Figure 1 As shown, in one embodiment of the present invention, the transition lining includes at least one second lining 12 and at least one third lining 13. Figures 8 to 10 As shown, the tenon 300 of the second straight edge 102 of the second lining plate 12 is a plate-like structure, and a gap is left between the side wall of the tenon 300 and the side wall of the corresponding tenon groove 200; Figures 11 to 13 As shown, the tenon 300 of the second straight side 102 of the third lining plate 13 is provided with a connection structure 100, and the connection structure 100 is used to detachably install the side of the third lining plate 13 on the inner peripheral wall of the cylinder. It can be understood that in this embodiment, by leaving a gap between the side wall of the tenon 300 of the second lining plate 12 and the side wall of the corresponding tenon groove 200 of the adjacent lining plate 10, as mentioned above, the gap can be used as a telescopic gap to provide a deformation space, thereby preventing the lining plates 10 from being deformed due to mutual compression when they expand due to heat; by arranging the connection structure 100 on the tenon 300 of the third lining plate 13, both straight sides of the third lining plate 13 can be connected to the inner peripheral wall of the cylinder, which is conducive to improving the connection stability between the third lining plate 13 and the cylinder, and further, based on the fixing effect of the mortise and tenon structure, the connection stability between other lining plates 10 spliced ​​adjacent to the third lining plate 13 and the cylinder can be improved.

[0079] Wherein, optionally, Figures 4 to 13 As shown, in one embodiment of the present invention, the connection structure 100 is a bolt connection structure. Specifically, the connection structure 100 includes a large-diameter countersunk hole and a small-diameter first threaded hole. The countersunk hole is provided on the side of the tenon 300 facing away from the cylinder. The first threaded hole is connected to the end of the countersunk hole close to the cylinder. A corresponding second threaded hole is provided on the inner circumferential wall of the cylinder. The bolt is inserted from the countersunk hole and threadedly connected to the corresponding connected first threaded hole and second threaded hole. The liner 10 can be detachably installed on the inner circumferential wall of the cylinder, and the bolt head can be accommodated in the countersunk hole. It is not difficult to understand that the bolt head can be fixed for a second time by welding, or it can be crimped and covered by the portion of the liner 10 corresponding to the tenon groove 200, and can also be fixed for a second time and hidden.

[0080] Preferably, please combine Figure 1 and Figures 4 to 13In one embodiment of the present invention, the ratio of the size of each lining plate 10 along the circumference of the cylinder (which can be understood as the width) to the thickness of the lining plate 10 is greater than or equal to 25. In this embodiment, by setting the ratio of the width of each lining plate 10 to the thickness to be greater than or equal to 25, each lining plate 10 has a certain flexibility. When there is a slight deviation in the size of the inner circumferential wall surface of the liner 1000 and the inner circumferential wall surface of the cylinder, due to the flexibility of the liner 10, the inner circumferential wall surface of the liner 1000 will be adaptively deformed according to the inner circumferential wall surface of the cylinder, thereby achieving a good arc surface fitting effect.

[0081] Preferably, Figures 8 to 13 As shown, in one embodiment of the present invention, the first straight edge 101 of the transition liner is provided with a tenon 300, and the connection structure 100 of the first straight edge 101 of the transition liner is arranged on the tenon 300. Among them, the surface of the tenon 300 of each transition liner facing away from the cylinder does not exceed the surface of the transition liner facing away from the cylinder, and the surface of the tenon 300 facing the cylinder and the surface of the transition liner facing the cylinder are located on the same circumferential surface; when the tenon 300 is received in the corresponding tenon groove 200, the surface of the transition liner and the other liner 10 connected to the transition liner facing away from the cylinder are located on the same circumferential surface, so that the inner circumferential wall surface of the liner 1000 is a smooth circumferential surface. In this embodiment, by providing the tenon 300 on the first straight edge 101 of the transition liner and arranging the connection structure 100 on the tenon 300, the two straight edges of each transition liner are provided with the tenon 300, so that the two straight edges can form a mortise and tenon structure with the adjacent liner 10, which is conducive to further improving the connection stability between the transition liner and the cylinder.

[0082] Among them, Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the number of the first lining plate 11, the second lining plate 12 and the third lining plate 13 can be one or more, as long as all the lining plates 10 included in each lining plate assembly 1 can be spliced ​​to form a ring.

[0083] It should be noted that, in other embodiments of the present invention, the transition liner may also include only at least one second liner 12 or only include at least one third liner 13, as long as it can be spliced ​​with at least one first liner 11 to form an annular liner assembly 1, and there is no limitation on this.

When the two liner 10 are spliced, the tenon 300 is received in the corresponding tenon groove 200 and is sandwiched between the inner peripheral wall of the cylinder and the portion of the liner 10 with the tenon groove 200 corresponding to the tenon groove 200.

[0086] In another embodiment of the present invention, the liner 1000 is composed of at least two liner assemblies 1 assembled in sequence in a ring along the circumferential direction of the cylinder, and each liner assembly 1 includes at least two arc-shaped liner plates 10 assembled in sequence along the axial direction of the cylinder. Figures 1 to 13 The same as the example, each lining plate 10 is detachably mounted on the inner circumferential wall of the cylinder through the fixing effect of the connecting structure 100 and / or the mortise and tenon structure, which can also protect the inner circumferential wall of the cylinder and prevent the inner circumferential wall of the cylinder from being worn or scratched by foreign objects.
