Description

Technical Field

[0001] The utility model relates to the technical field of telescopic furnace pipe insulation, in particular to a double-sided telescopic furnace pipe insulation sleeve which is easy to connect. Background Art

[0002] The furnace tube is one of the most core components of an industrial furnace. Because the wall temperature of the furnace tube is very high, its own expansion is large, and the flue gas temperature in the furnace is very high, it is necessary to take better sealing and insulation measures for the part of the furnace tube that passes through the furnace.

[0003] The existing double-sided telescopic furnace pipe insulation sleeves that are easy to connect are generally improved to address the problem that the insulation materials are prone to cracking during repeated deformation. For example, the authorized Chinese patent CN209945019U discloses a double-sided telescopic furnace pipe insulation sleeve that is easy to connect. The sleeve can shrink and deform along with the thermal expansion of the furnace pipe through the cooperation of structures such as the first connecting insulation board, the second connecting insulation board, the outer environmental insulation board, the telescopic groove, the elastic band, the telescopic insulation board, the telescopic band, the aluminum silicate refractory fiber cotton, the outer ring flexible protective layer, the inner ring flexible protective layer and the inner environmental insulation board, thereby preventing the many troubles caused by the breakage of the insulation sleeve. At the same time, Velcro and snap fasteners are arranged on the first connecting insulation board and the second connecting insulation board to facilitate the connection of the insulation sleeve to the furnace pipe.

[0004] However, the insulation cover in the above cited document is only connected to the furnace pipe by Velcro, snap fasteners and elastic bands, and is directly bonded and fixed during connection. It cannot be adjusted according to the size of the furnace pipe and cannot be applied to pipes of different shapes to make it fit the furnace pipe more closely. As a result, the use effect of the existing furnace pipe insulation cover needs to be improved. Utility Model Content

At the same time, it can also be adaptively adjusted during installation to make it more closely fit the surface of the furnace pipe, so as to achieve better thermal insulation effect, thereby effectively improving the use effect of the existing furnace pipe insulation cover.

[0029] In this embodiment, the heat-resistant Velcro assembly 400 is a structure used to reinforce the insulation sleeve after it is installed on the furnace pipe.

[0030] like Figure 1 As shown, the heat-resistant Velcro assembly 400 includes a connecting elastic band 401, a barbed surface layer 402 and a round surface layer 403; one end face of the connecting elastic band 401 is fixedly connected to one side of the opening, and the round surface layer 403 is sewn on the outer side of the outer layer of fireproof and heat-resistant insulating felt 3 through a reinforcing line, and the position corresponds to the barbed surface layer 402, and the barbed surface layer 402 is fixedly connected to one side of the connecting elastic band 401; one side of the barbed surface layer 402 is elastic fiber with hooks and barbs, and the side of the round surface layer 403 corresponding to the barbed surface layer 402 is soft fiber, and the barbed surface layer 402 can be tightly buckled with the round surface layer 403 in order to reinforce the insulation cover after it is installed on the furnace pipe.

[0033] It should be noted that a plurality of equidistantly arranged insertion holes 502 are provided on one side of the elastic band 501 in order to increase the adjustment range.

[0034] It can be understood that the adjustable fastening assembly includes a limiting partition 5051, a trapezoidal block 5052, a return spring 5053 and an insertion rod 5054; the outer side of the limiting partition 5051 is fixedly installed on the inner side of the adjustment box 504, and the outer side of the trapezoidal block 5052 is slidably connected between the limiting partition 5051 and the opposite side of the adjustment box 504, one end of the return spring 5053 is fixedly connected to one side of the trapezoidal block 5052, and the other end is fixedly connected to the inner wall of the adjustment box 504. When the trapezoidal block 5052 is moved, the return spring 5053 can be driven to elastically contract, and the insertion rod 5054 moves with the trapezoidal block 5052 to facilitate the user to adjust the tightness.

[0035] In addition, a slot 506 for the insertion rod 5054 to fit and engage is provided on the inner wall of the fixed hollow block 503.

This is to allow the insertion rod 5054 to limit the movement of the elastic band 501 and to further enhance stability.

[0036] In this embodiment, the pushing assembly includes a push rod 5071, a circular push handle 5072 and a trapezoidal moving block 5073; one end of the push rod 5071 is fixedly connected to one side of the circular push handle 5072, and the other end passes through the adjustment box 504, the auxiliary moving assembly and the limiting partition 5051 in sequence and extends to one side of the trapezoidal moving block 5073 and is fixedly connected to the trapezoidal moving block 5073, and pushes the push rod 5071 to move and drives the trapezoidal moving block 5073 to move under the thrust of the circular push handle 5072; the inclined surface of the trapezoidal moving block 5073 slides in contact with the inclined surface of the trapezoidal block 5052, and a sliding hole 508 is provided on one side of the limiting partition 5051 for the push rod 5071 to slide in contact with, so as to be able to push the trapezoidal block 5052 to move.

[0039] It should be further explained that the trapezoidal moving block 5073 is projected in the first direction to form a rectangle with a length and a width of L. The first direction is parallel to the depth direction of the sliding hole 508. The aperture of the sliding hole 508 is D. L>D is to prevent the trapezoidal moving block 5073 from falling off from the sliding hole 508.

[0040] The working principle of the above embodiment is:

[0041] When installing the heat-insulating sleeve on the furnace pipe, firstly, the contact layer heat-resistant fabric 1 is put on the outer side of the furnace pipe so that the contact layer heat-resistant fabric 1 contacts the furnace pipe, and then the elastic fiber with hooks and barbs on the barbed surface layer 402 is fitted and fixed with the soft fiber on the round surface layer 403, and then one hand presses the round push handle 5072 toward the ground, at this time, a thrust toward the ground is generated, and the push rod 5071 is stably pushed to move under the sliding connection of the adjustment block 5092 and the adjustment slot 510 on the moving slide plate 5091, and the trapezoidal moving block 5073 is driven to move. The slidably connected trapezoidal block 5052 moves, and then under the driving force generated by the movement of the trapezoidal block 5052, the return spring 5053 continuously contracts elastically, and the insertion rod 5054 moves with the trapezoidal block 5052. When the insertion rod 5054 is separated from the slot 506, one end of the elastic band 501 is passed through the fixed hollow block 503 and adjusted to a suitable range and tightened, and then the circular push handle 5072 is loosened, and the insertion rod 5054 is aligned with the corresponding socket 502 and passed through. After being engaged with the slot 506, the insulation cover can be further reinforced.

[0042] Compared with the prior art: the double-sided telescopic furnace pipe insulation cover that is easy to connect can be suitable for furnace pipes of different shapes through the mutual cooperation between the thermal insulation material 2 on the contact layer heat-resistant fabric 1, the outer layer fireproof and heat-resistant insulation felt 3, the temperature-resistant Velcro component 400 and the adjustable elastic mechanism 500, making its application range wider. At the same time, it can also be adaptively adjusted during installation to make it more closely fit the surface of the furnace pipe, so as to achieve better insulation effect, thereby effectively improving the use effect of the existing furnace pipe insulation cover and solving the problem of poor use effect of the existing furnace pipe insulation cover.
