Description

Technical Field

[0001] The utility model relates to the technical field of roller kilns, in particular to a highly efficient and adjustable roller kiln frame and a roller kiln. Background Art

[0002] Roller kiln is a kind of kiln that uses rotating conveyor rollers as a carrier for green bodies to achieve continuous firing. It is mainly used for firing ceramic building materials such as tiles. At present, the roller kiln includes a kiln body, a frame and a conveyor roller group composed of multiple conveyor rollers. The axis of the conveyor roller is perpendicular to the length direction of the kiln body. The rotation of the conveyor roller promotes the transfer of ceramic green bodies from the kiln head to the kiln tail. Among them, the frame includes sub-frames arranged at intervals above and below, and the upper and lower sub-frames are fixed by welding with I-beams.

[0003] During the assembly process of the roller kiln, it is required that the conveyor rollers and I-beams should not be too close. However, after the roller kiln is heated up, the I-beams and conveyor rollers come into contact, which interferes with the conveyor rollers. In addition, due to site limitations, some long roller kilns use a circuitous structure, which results in a small distance between the I-beams and the conveyor rollers, causing the conveyor rollers to easily rub against the I-beams. The above situation will cause damage to the I-beams and conveyor rollers, affecting the structural stability and service life of the roller kiln. Utility Model Content

[0029] Reference below Figures 1 to 3 The invention describes a highly efficient and adjustable roller kiln frame and a roller kiln provided according to an embodiment of the utility model.

[0030] like Figures 1 to 3 As shown, the efficient and adjustable roller kiln frame according to the embodiment of the first aspect of the utility model can efficiently adjust the position of the support member 200 relative to the conveying roller, so that the support member 200 can avoid the conveying roller, effectively avoiding the friction between the support member 200 and the conveying roller, which may cause serious damage to the support member 200 and the conveying roller, thereby ensuring that the roller kiln has strong structural stability and a long service life.

[0031] The highly efficient and adjustable roller kiln frame has a first direction, a second direction and an up-down direction, wherein the first direction, the second direction and the up-down direction are perpendicular to each other. In this embodiment, it is assumed that the first direction is the front-back direction and the second direction is the left-right direction.

[0032] The highly efficient and adjustable roller kiln frame comprises a frame body and a supporting assembly.

[0033] The length of the frame body extends along the first direction. The structure of the frame body includes a first frame 110 and a second frame 120. The first frame 110 is located above the second frame 120. The first frame 110 and the second frame 120 are arranged opposite to each other up and down, and there is a certain height gap between the first frame 110 and the second frame 120. It can be understood that the first frame 110 and the second frame 120 can be formed by connecting a plurality of profiles along the front-to-back direction, the left-to-right direction, and the up-down direction.

[0034] The frame body is provided with support components on opposite sides along the second direction. Specifically, the support components are arranged in the gap between the first frame 110 and the second frame 120. Under the connection of the support components, the first frame 110 can maintain a stable state relative to the second frame 120. It can be understood that the support components on both sides of the frame body in the second direction can be arranged symmetrically or asymmetrically.

[0035] The structure of the support assembly includes a plurality of support members 200 and a plurality of threaded fasteners 300 .

[0036] Among them, a plurality of support members 200 are arranged at a certain interval along the first direction. The support member 200 is U-shaped, and the support member 200 has a U-shaped opening, and the U-shaped opening of the support member 200 faces either side of the first direction. It is understandable that in order to avoid the conveying roller, the spacing distance between the support members 200 can be adjusted arbitrarily. The U-shaped openings of some support members 200 can be arranged forward, and the U-shaped openings of other support members 200 can be arranged backward. Of course, the U-shaped openings of all support members 200 can also be arranged in the same direction as before.

[0037] The upper and lower ends of the support member 200 are both provided with a long hole 240, the length of the long hole 240 extends along the first direction, and the long hole 240 is penetrated in the up-down direction. Each support member 200 is provided with two threaded fasteners 300, one of which is located at the upper end of the support member 200, and the other threaded fastener 300 is located at the lower end of the support member 200.

[0038] Specifically, the structure of the support member 200 includes a first plate 210, a second plate 220 and a third plate 230. The length of the first plate 210 and the length of the second plate 220 both extend along the first direction, the length of the third plate 230 extends along the up-down direction, the first plate 210 is located above the second plate 220, the first plate 210 and the second plate 220 are arranged opposite to each other up and down, the upper end of the third plate 230 is fixedly connected to one end of the first plate 210, and the lower end of the third plate 230 is fixedly connected to one end of the second plate 220, thereby forming a U-shaped support member 200.

[0039] In this embodiment, if Figure 2 As shown in (a), the support member 200 is a steel member, which has sufficient strength, can provide sufficient support, and is not easy to deform. The first plate 210, the second plate 220 and the third plate 230 are integrally formed by a bending process. Specifically, the steel plate is subjected to a bending process to bend the upper end of the third plate 230 to form the first plate 210, and the lower end of the third plate 230 to form the second plate 220. At this time, the connection between the first plate 210 and the third plate 230 is a rounded corner, and the connection between the second plate 220 and the third plate 230 is a rounded corner. The support member 200 is manufactured by a bending forming process, so that the support member 200 has high strength and is convenient and quick to process.

[0040] Of course, it is not excluded that one end of the first plate 210 is fixed to the upper end of the third plate 230 by welding, and one end of the second plate 220 is fixed to the lower end of the third plate 230 by welding.

[0041] The first plate 210 and the second plate 220 are both provided with a long hole 240, and the upper and lower long holes 240 are arranged opposite to each other in the upper and lower directions, and the first plate 210 and the second plate 220 have the same size. The third plate 230 is located outside the projection area of ​​the long hole 240 in the upper and lower directions. In this embodiment, the long hole 240 is a waist-shaped hole, which is easy to process. Of course, it is not ruled out that the long hole 240 is a rectangular hole.

[0042] The first frame 110 is fixedly connected to the elongated hole 240 at the upper end of the support member 200 by means of threaded fasteners 300, and the second frame 120 is fixedly connected to the elongated hole 240 at the lower end of the support member 200 by means of threaded fasteners 300. The first frame 110 is fixedly connected to the upper end of the support member 200 by means of one threaded fastener 300, and the second frame 120 is fixedly connected to the lower end of the support member 200 by means of the other threaded fastener 300.

[0043] Specifically, the first frame 110 is provided with a first crossbeam 111, and the second frame 120 is provided with a second crossbeam 121. The first frame 110 is provided with first crossbeams 111 on opposite sides along the second direction, the length of the first crossbeam 111 extends along the first direction, and the first crossbeam 111 is located at the lower end of the first frame 110. The second frame 120 is provided with second crossbeams 121 on opposite sides along the second direction, and the length of the second crossbeam 121 extends along the first direction. In this embodiment, the first crossbeam 111 and the second crossbeam 121 are square tubes.

[0044] The first crossbeam 111 is provided with a plurality of connection holes along its extension direction. Similarly, the second crossbeam 121 is provided with a plurality of connection holes along its extension direction. All the connection holes are arranged at certain intervals. The connection holes are through-through. The upper and lower ends of the support member 200 are provided with threaded fasteners 300. After passing through the long holes 240, the threaded fasteners 300 are connected to the connection holes, so that the upper end of the support member 200 is fixedly connected to the first crossbeam 111, and the lower end of the support member 200 is fixedly connected to the second crossbeam 121, so that the first frame 110 is firmly fixed on the second frame 120.

[0045] It is understood that in some examples, the connection hole is a threaded hole, and the threaded fastener 300 is a bolt 310, which passes through the elongated hole 240 and is connected to the connection hole. Figure 3 As shown, the connecting hole is a round hole with a smooth wall, and the threaded fastener 300 includes a bolt 310 and a nut 320. The bolt 310 passes through the elongated hole 240 and the connecting hole, and is fixedly connected with the nut 320.

[0046] Further, such as Figure 3 As shown, the threaded fastener 300 also includes a gasket 330, which can be a metal flat gasket. The bolt 310 passes through the long hole 240, the connecting hole and the gasket 330, and is connected to the nut 320. By providing the gasket 330, the connection between the support member 200 and the first beam 111 and the second beam 121 is strengthened, so as to prevent the threaded fastener 300 from being easily loosened when the roller kiln is running.

[0047] It can be understood that, compared with the existing I-beam, in the case of the same size, the support member 200 of this embodiment adopts a U-shaped structure, and the third plate 230 is arranged on the same side of the first plate 210 and the second plate 220, which provides the possibility of manufacturing a sufficiently long long hole 240 on the first plate 210 and the second plate 220, thereby increasing the position adjustment range of the support member 200 along the first direction, ensuring that the support member 200 will not contact and rub against the conveying roller. Moreover, for the upper end of the support member 200, the bolt 310 is passed from bottom to top through the long hole 240 and the connecting hole of the first beam 111, and connected with the nut 320, which can enhance the connection between the support member 200 and the first beam 111, and avoid the interference of the bolt 310 on the conveying roller. Similarly, for the lower end of the support member 200, passing the bolt 310 from top to bottom through the long hole 240 and the connecting hole of the second beam 121 and connecting with the nut 320 can strengthen the connection between the support member 200 and the second beam 121 and prevent the bolt 310 from interfering with the conveyor roller.

[0048] like Figures 1 to 3As shown, during the use of the efficient and adjustable roller kiln frame of the first aspect of the utility model, a support assembly is provided between the first frame 110 and the second frame 120, so that the first frame 110 and the second frame 120 are connected and fixed to form a roller kiln frame with a stable structure.

[0049] In the support assembly, the U-shaped support member 200 is provided with long holes 240 at both ends thereof, the first frame 110 is connected to the long hole 240 at the upper end of the support member 200 by means of a threaded fastener 300, and the second frame 120 is connected to the long hole 240 at the lower end of the support member 200 by means of a threaded fastener 300. Moreover, the U-shaped opening of the support member 200 faces either side of the first direction. Therefore, during the installation of the roller kiln, when the distance between the conveyor roller and the support member 200 is too small and friction between the two is likely to occur, the threaded fastener 300 can be used to fix the long hole 240 at the upper end of the support member 200. The loosening operation drives the support member 200 to move along the first direction, increasing the distance between the third plate 230 of the support member 200 and the conveying roller, thereby efficiently adjusting the position of the support member 200 in the first direction, enabling the support member 200 to avoid the conveying roller of the roller kiln. After the position adjustment is completed, the threaded fastener 300 is tightened, which can effectively prevent the conveying roller and the support member 200 from contacting and rubbing during the operation of the roller kiln, thereby protecting the conveying roller and the support member 200 and ensuring that the roller kiln is stable, reliable, safe and durable.

[0050] The roller kiln according to the second embodiment of the utility model comprises a conveying roller and a highly efficient and adjustable roller kiln frame as in the first embodiment.

[0051] The length of the conveying roller extends along the second direction, there are a plurality of conveying rollers, and all the conveying rollers are arranged at intervals along the first direction. The support member 200 is arranged to avoid the conveying rollers.

[0052] It is understandable that in some examples, the roller kiln is a long straight kiln. In other examples, the roller kiln is a rotary kiln. All the support members 200 and all the conveying rollers are arranged at intervals along the extension direction of the roller kiln, and the third plate 230, the first plate 210 and the second plate 220 of the support member 200 are all spaced apart from the conveying rollers to avoid contact friction between the two.

[0053] In the structure of the roller kiln, a plurality of detachably connected support members 200 are used to connect the first frame 110 and the second frame 120 to form a roller kiln frame. After the roller kiln is assembled, if the conveying roller and the support member 200 are too close, the threaded fasteners 300 on the upper and lower sides of the support member 200 can be operated to drive the support member 200 to move along the first direction, thereby quickly adjusting the position of the support member 200 in the first direction, so that the support member 200 can avoid the conveying roller, thereby avoiding interference between the support member 200 and the conveying roller, which may affect the structural stability and service life of the roller kiln.
