Description

Technical Field

[0001] This utility model relates to the field of insulation sleeve technology, and in particular to an insulation sleeve for a reduction furnace. Background Technology

[0002] In the chemical and metallurgical fields, reduction furnaces are key equipment for high-temperature reduction reactions. Their operation consumes a lot of energy, and their heat preservation performance directly affects production efficiency and energy utilization.

[0003] Currently, traditional reduction furnaces mostly use fixed insulation layers or integral rigid insulation structures. Although this can reduce heat loss from the furnace side walls, the furnace top and feed inlet areas are often not insulated due to their complex structure and frequent opening and closing, resulting in weak insulation links. Therefore, it is necessary to design a reduction furnace insulation sleeve. Utility Model Content

[0004] The purpose of this invention is to provide a heat insulation sleeve for a reduction furnace to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A reduction furnace insulation sleeve includes a flexible insulation sleeve comprising an insulation cylindrical sleeve and an insulation cap. The insulation cylindrical sleeve is fitted onto the outer wall of the reduction furnace and is used to insulate the periphery of the side wall of the reduction furnace. The insulation cap is detachably installed on the top of the insulation cylindrical sleeve and is used to insulate the top of the reduction furnace. The insulation cap is provided with a clearance opening for feeding into the reduction furnace feed inlet and a sealing unit is provided on the insulation cap for sealing the clearance opening.

[0006] By adopting the above technical solution, the flexible insulation sleeve is divided into two parts: an insulation cylindrical sleeve and an insulation cap. This can achieve comprehensive insulation of the perimeter and top of the reduction furnace sidewall, reducing heat loss from key parts of the furnace. At the same time, the clearance opening on the insulation cap can ensure normal feeding at the feed inlet. Combined with the sealing effect of the sealing unit on the clearance opening, heat leakage at the feeding gap can be avoided, further ensuring the overall insulation effect of the reduction furnace.

[0007] In a further embodiment, the sealing unit includes an insulating sleeve and a zipper, one side of the zipper is sewn along the periphery of the clearance opening, and the other side of the zipper is sewn to the bottom edge of the insulating sleeve.

[0008] By adopting the above technical solution and utilizing the opening and closing characteristics of the zipper, the zipper can be opened during the feeding operation to fold the insulation sleeve upwards, exposing the clearance opening for the feed pipe to enter. After feeding is completed, the zipper can be closed again to allow the insulation sleeve to cover the clearance opening area again. This not only meets the needs of the feeding operation, but also fills the insulation gap at the clearance opening through the insulation performance of the insulation sleeve.

[0009] In a further embodiment, the insulating cylindrical sleeve is composed of multiple insulating sheets, and adjacent insulating sheets are detachably connected by Velcro.

[0010] By adopting the above technical solution, the insulation cylindrical sleeve is disassembled into a multi-piece structure. During installation, each piece is spliced ​​against the side wall of the furnace body according to the actual diameter and outer wall curvature of the reduction furnace. Unlike the integral cylindrical sleeve, it does not need to be inserted from the end of the furnace body. This is especially suitable for reduction furnaces that are already fixedly installed in the production line. At the same time, the Velcro connection method not only makes disassembly and disassembly convenient, but also allows for the replacement of only the damaged insulation piece when a single insulation piece is damaged or aged, without replacing the entire cylindrical sleeve. Furthermore, the adhesive of the Velcro ensures that adjacent insulation pieces are tightly bonded, reducing heat loss from the seams.

[0011] In a further embodiment, the bottom edge of the thermal insulation cylindrical sleeve is provided with multiple positioning buckles at circumferential intervals.

[0012] By adopting the above technical solution, the positioning buckle is adapted and engaged with the pre-set snap-fit ​​part at the bottom of the reduction furnace, thereby the positioning buckle is used to limit the displacement of the insulation cylinder sleeve.

[0013] In a further embodiment, the inner wall of the heat-insulating cap is provided with an annular support ring, the outer diameter of which is adapted to the inner diameter of the bottom end of the heat-insulating cylindrical sleeve.

[0014] By adopting the above technical solution, the support ring is used to support the shape of the heat-insulating cap.

[0015] In a further embodiment, multiple rings are fixedly installed on the outer side of each of the insulation sheets.

[0016] By adopting the above technical solution, a ring is provided for the reinforcing strap to be threaded through, and the reinforcing strap is wrapped around the circumference of the insulation cylindrical sleeve and then the two ends of the reinforcing strap are manually tightened to enhance the overall tightness of the insulation cylindrical sleeve structure.

[0017] In summary, this utility model has the following beneficial effects: 1. By splitting the flexible insulation jacket into two parts, an insulation cylindrical sleeve and an insulation cap, it is possible to achieve comprehensive insulation of the perimeter and top of the reduction furnace sidewalls, reducing heat loss from key parts of the furnace body. At the same time, the clearance opening on the insulation cap ensures normal feeding at the feed inlet. Combined with the sealing effect of the sealing unit on the clearance opening, heat leakage at the feeding gap can be prevented, which can further ensure the overall insulation performance of the reduction furnace.

[0022] Example 1: like Figures 1-2 As shown, a reduction furnace insulation sleeve includes a flexible insulation sleeve 1, which comprises an insulation cylindrical sleeve 11 and an insulation cap 12. The insulation cylindrical sleeve 11 is fitted onto the outer wall of the reduction furnace and is used to insulate the periphery of the side wall of the reduction furnace. The insulation cap 12 is detachably installed on the top of the insulation cylindrical sleeve 11 and is used to insulate the top of the reduction furnace. The insulation cap 12 is provided with a clearance opening for feeding into the reduction furnace feed inlet, and a sealing unit 2 is provided on the insulation cap 12 to seal the clearance opening. The sealing unit 2 includes an insulation sleeve 21 and a zipper 22. One side of the zipper 22 is sewn along the periphery of the clearance opening, and the other side of the zipper 22 is sewn to the bottom edge of the insulation sleeve 21; the insulation sleeve is composed of multiple insulation sheets, and adjacent insulation sheets are detachably connected by Velcro; multiple positioning buckles are provided circumferentially at intervals along the bottom edge of the insulation sleeve 11, and the positioning buckles are adapted to and engaged with the pre-set snap-fit ​​part at the bottom of the reduction furnace, and the positioning buckles are used to limit the displacement of the insulation sleeve 11; the inner wall of the insulation cap 12 is provided with an annular support ring, and the outer diameter of the support ring is adapted to the bottom inner diameter of the insulation sleeve 11; multiple rings 3 are fixedly installed on the outer side of each insulation sheet.

[0023] Specific implementation process: When installing the insulation sleeve of the reduction furnace, first process the insulation cylindrical sleeve. Match and engage the multiple positioning buckles on the bottom edge of the insulation cylindrical sleeve with the pre-set locking parts at the bottom of the reduction furnace. This provides positioning and prevents the insulation cylindrical sleeve from shifting. Since it is composed of multiple insulation sheets, the insulation sheets are then attached one by one to the side wall of the furnace body. After assembly, the insulation cap is installed, detachably mounted on the top of the insulation cylindrical sleeve. The annular support ring on the inner wall of the insulation cap supports its shape, and the clearance opening on the insulation cap allows access to the reduction furnace feed inlet. During the feeding process, unzip the closed unit, fold the insulation sleeve upwards to expose the clearance opening, and allow the feed pipe to connect. After feeding is complete, zip the sleeve back up to cover the clearance opening area and fill the insulation gap. In addition, to enhance the overall tightness of the insulation cylinder sleeve structure, reinforcing straps are threaded through the outer ring of each insulation piece, wrapped around the circumference of the insulation cylinder sleeve, and then the two ends of the straps are manually tightened. This fully wraps and insulates the perimeter and top of the reduction furnace sidewall, reduces heat loss, and ensures the overall insulation effect of the reduction furnace.
