[0002] The mobile vertical expansion furnace for perlite is a specialized piece of equipment for on-site, enclosed production of expanded perlite, primarily used for filling insulation materials in large liquefied natural gas storage tanks, cryogenic liquid storage tanks, and other similar installations. Its core advantages lie in its ease of movement, enclosed operation mode, and effective guarantee of the thermal conductivity of the perlite.

[0003] A Chinese patent with authorization announcement number CN216716954U discloses a mobile vertical perlite expansion furnace, which includes a frame, an inner cylinder, an outer cylinder, a burner, and an induced draft fan.

[0044] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0045] This application discloses an inner cylinder support device for a mobile vertical expansion furnace for perlite.

[0046] A mobile vertical expansion furnace for perlite includes an inner cylinder 1, an outer cylinder 2, and a frame. The inner cylinder 1 is located inside the outer cylinder 2 and is connected to the outer cylinder 2 through a support device 3. The outer cylinder 2 is fixedly installed on the frame, and the frame is fixedly installed in the working area.

[0047] A perlite mobile vertical expansion furnace has multiple support devices 3 along the axial direction of the inner cylinder 1. The support stability of the inner cylinder 1 is improved by multiple support devices 3. In this embodiment, there are four support devices 3.

[0048] A support device 3 for the inner cylinder 1 of a perlite mobile vertical expansion furnace includes a first limiting seat 4 and a second limiting seat 5. The first limiting seat 4 is disposed on the inner cylinder 1, and the second limiting seat 5 is disposed in a fixed position. The second limiting seat 5 is provided with a limiting area 6 for the first limiting seat 4 to move.

[0049] In this embodiment, the first limiting seat 4 is disposed on the outer wall of the inner cylinder 1, and the second limiting seat 5 is disposed at the top of the outer cylinder 2. After the first limiting seat 4 is placed inside the limiting area 6 of the second limiting seat 5, the outer cylinder 2 supports the first limiting seat 4 through the second limiting seat 5, thereby limiting and supporting the inner cylinder 1, improving the placement stability of the inner cylinder 1. When the inner cylinder 1 undergoes collision deformation due to heat, the inner cylinder 1 causes the first limiting seat 4 to move within the limiting area 6, thus ensuring the installation stability of the inner cylinder 1 and facilitating the adaptation to the deformation caused by heat. Compared with welding or other connection methods that fix the inner cylinder 1 to the outer cylinder 2, this reduces the possibility of the fixed part of the inner cylinder 1 and the outer cylinder 2 breaking or even tearing the inner cylinder 1 when the inner cylinder 1 expands and deforms.

[0050] The first limiting seat 4 includes a limiting unit 41 and an installation unit 42. The limiting unit 41 is installed on the outer wall of the inner cylinder 1 through the installation unit 42.

[0051] In this embodiment, the mounting unit 42 is plate-shaped and is installed on the outer wall of the inner cylinder 1 by welding. In order to improve the connection stability between the mounting unit 42 and the inner cylinder 1, the mounting unit 42 is provided with an arc surface on the side near the inner cylinder 1. The arc surface on the mounting unit 42 fits against the outer wall of the inner cylinder 1. By increasing the contact area between the mounting unit 42 and the inner cylinder 1, the connection stability between the mounting unit 42 and the inner cylinder 1 is improved. At the same time, the local structural strength of the inner cylinder 1 is enhanced, and the possibility of the inner cylinder 1 breaking is reduced.

[0052] The limiting unit 41 is generally arranged in an inverted cross shape. The limiting unit 41 includes a limiting plate 411 and a guide bar 412. The guide bar 412 is located on the side of the installation unit 42 away from the inner cylinder 1. The length direction of the guide bar 412 is consistent with the axial direction of the inner cylinder 1. The guide bar 412 and the installation unit 42 are generally arranged in a T shape. In this embodiment, the guide bar 412 and the installation unit 42 are integrally formed. The guide bar 412 not only limits the movement direction of the limiting unit 41, but also serves as a reinforcing rib of the installation unit 42 to improve the structural strength of the installation unit 42.

[0053] The limiting plate 411, guide strip 412 and mounting unit 42 are perpendicular to each other. The limiting plate 411 divides the guide strip 412 into a positioning section 413 and a guide section 414 in the vertical direction.

[0054] In this embodiment, the limiting plate 411 is horizontally arranged, and the limiting plate 411 is provided with a snap-fit ​​groove 4111 on the side near the guide strip 412. The guide strip 412 and the snap-fit ​​groove 4111 are inserted and engaged. When the limiting plate 411 is installed on the guide strip 412, the limiting plate 411 is snapped onto the guide strip 412 through the snap-fit ​​groove 4111, and the limiting plate 411 moves on the guide strip 412, thereby adjusting the range of the positioning section 413 and the guide section 414.

[0055] After the positions of the limiting plate 411 and the guide strip 412 are adjusted, the limiting plate 411 and the guide strip 412 can be welded together. When the limiting plate 411 is fixed on the guide strip 412, the guide strip 412 limits the limiting plate 411 through the inner wall of the snap-fit ​​groove 4111, which makes it easy for the limiting plate 411 and the guide strip 412 to be in a vertical state. When connecting the guide strip 412 and the limiting plate 411, the guide strip 412 is directly welded to the inner wall of the snap-fit ​​groove 4111, which also improves the convenience of connecting the guide strip 412 and the limiting plate 411.

[0056] The guide section 414 of the limiting strip is also provided with a positioning hole 4121. A limiting pin can be inserted into the positioning hole 4121, and the limiting pin further limits the limiting plate 411.

[0057] The second limiting seat 5 includes a fixed unit 51 and a movable unit 52. The movable unit 52 and the fixed unit 51 are connected by a locking unit, and the distance between the movable unit 52 and the fixed unit 51 is adjustable. A limiting area 6 is formed between the movable unit 52 and the fixed unit 51. The size of the limiting area 6 is adjusted by pre-calculating the expansion range of the inner cylinder 1, so as to adapt to the different deformation sizes of different models of inner cylinder 1.

[0058] When the inner cylinder 1 expands and deforms due to heat, the mounting plate pushes the limiting plate 411 and the guide strip 412 to move within the limiting area 6, thereby accommodating the possibility of the inner cylinder 1 expanding due to heat.

[0059] The fixing unit 51 is U-shaped with its opening facing upwards. The movable unit 52 is placed inside the fixing unit 51. When the limiting plate 411 is placed inside the limiting area 6, the fixing unit 51 limits the limiting plate 411 through its side wall. This ensures the installation stability of the inner cylinder 1 and reduces the possibility of large-scale movement of the inner cylinder 1, even when the inner cylinder 1 expands due to heat and the limiting plate 411 moves horizontally.

[0060] The fixed unit 51 is provided with a first mounting hole 511, and the movable unit 52 is provided with a second mounting hole 521. The locking unit is a bolt and nut. The bolt and nut connect the movable unit 52 and the fixed unit 51 through the first mounting hole 511 and the second mounting hole 521. Multiple first mounting holes 511 and second mounting holes 521 can be provided to improve the connection stability. In this embodiment, two first mounting holes 511 and two mounting holes 521 are provided.

[0061] Connecting the fixed unit 51 and the movable unit 52 with bolts and nuts not only improves the convenience of connecting the fixed unit 51 and the movable unit 52, but also facilitates the adjustment of the distance between the fixed unit 51 and the movable unit 52, so as to adjust the size of the limiting area 6.

[0062] The movable unit 52 and the limiting pin work together to limit the limiting plate 411. After the movable unit 52 fails, the limiting pin is limited by the fixed unit 51, reducing the possibility of the inner cylinder 1 sliding directly down.

[0063] The first mounting hole 511 is set in the shape of an oblong hole, which facilitates the fine adjustment of the relative position between the fixed unit 51 and the movable unit 52, so as to adapt to different installation positions and reduce the influence of workpiece error.

[0064] After the fixing unit 51 is placed on the top of the outer cylinder 2, the fixing unit 51 is fixed on the outer cylinder 2. In this embodiment, the fixing unit 51 is welded to the outer cylinder 2.

[0065] The fixed unit 51 is provided with a positioning member 512, which is located on the side of the fixed unit 51 away from the movable unit 52. In this embodiment, the positioning member 512 is set in the form of a triangular plate, and the side of the triangular plate is fixedly installed at the bottom of the fixed unit 51.

[0066] When the fixing unit 51 is placed, the positioning member 512 is positioned by contacting the inner wall of the outer cylinder 2. When the fixing unit 51 supports the inner cylinder 1, the inner wall of the outer cylinder 2 supports the fixing unit 51 by the positioning member 512.

[0067] The positioning element 512 and the outer cylinder 2 work together to support the fixing unit 51, thereby improving the stability of the support for the fixing unit 51 and reducing the possibility of deformation of the inner cylinder 1 caused by the deformation of the fixing unit 51 during the process of supporting the inner cylinder 1. At the same time, the stability of the fixing unit 51 is improved, which also indirectly improves the support stability of the inner cylinder 1.

[0068] When supporting the fixed unit 51, the stability of the triangular plate further enhances the stability of the fixed unit 51.

[0069] The fixed unit 51 is provided with a first positioning groove 513 that is inserted and cooperates with the first limiting seat 4; the movable unit 52 is provided with a second positioning groove 522 that is inserted and cooperates with the first limiting seat 4.

[0070] The first positioning groove 513 and the guide section 414 of the guide bar 412 are inserted into each other, and the second positioning groove 522 and the positioning section 413 of the guide bar 412 are inserted into each other, so that the limiting plate 411 can be placed in the limiting area 6. When the inner cylinder 1 expands and deforms, the limiting plate 411 moves inside the limiting area 6, and the moving direction of the limiting plate 411 is limited, thereby adjusting the overall deformation shape of the inner cylinder 1.

[0071] The implementation principle of the perlite mobile vertical expansion furnace inner cylinder support device 3 in this application embodiment is as follows: When the perlite mobile vertical expansion furnace is working, the inner cylinder 1 expands and deforms due to heat, pushing the first limiting seat 4 to move within the limiting area 6 of the second limiting seat 5. The mounting unit 42 of the first limiting seat 4 fits against the outer wall of the inner cylinder 1 through its arc surface, enhancing the connection stability; the guide strip 412 and the limiting plate 411 of the limiting unit 41 work together to limit the expansion direction of the inner cylinder 1. The fixing unit 51 and the movable unit 52 of the second limiting seat 5 are connected by bolts and nuts, and the spacing can be adjusted to adapt to the expansion range of the inner cylinder 1. The positioning part 512 of the fixing unit 51 contacts and positions itself against the inner wall of the outer cylinder 2, enhancing the overall support stability. Through this combination of limiting and supporting, the installation stability of the inner cylinder 1 is ensured, and its thermal deformation is accommodated, reducing the risk of breakage or tearing at the connection between the inner cylinder 1 and the outer cylinder 2 due to expansion, and improving the reliability of equipment operation.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
