Description

Technical Field

[0001] This utility model relates to the field of thermal insulation layer technology, and in particular to the structure of carbon felt thermal insulation layer for sintering furnaces. Background Technology

[0002] Carbon felt insulation in sintering furnaces is a highly efficient thermal insulation material used to reduce heat loss and maintain temperature uniformity within the furnace. A common structural feature of carbon felt insulation in sintering furnaces is its multi-layered composite structure: typically composed of multiple layers of carbon felt, including soft and hard carbon felt. These layers may be arranged in specific combinations to enhance insulation performance. The structure of the carbon felt insulation layer in a sintering furnace is carefully designed to maximize thermal efficiency while ensuring operational safety and stability.

[0003] In existing technologies, most insulation layer structures are assembled from a single structure or large insulation blocks. In such cases, if the insulation layer is damaged, it will affect subsequent insulation work if it is not repaired. If repair is required, the operator needs to replace the entire insulation layer or the entire side of the insulation layer, which makes the cost of repair and restoration after damage relatively large. If only a small part of the insulation layer is damaged on one side, it will result in a certain degree of waste of the undamaged parts. Utility Model Content

[0007] According to the sintering furnace carbon felt insulation layer structure, the first insertion hole corresponds to the second insertion hole, the baffle bar passes through the interior of the first insertion hole, and the baffle bar is slidably connected to the first insertion hole.

[0008] According to the sintering furnace carbon felt insulation layer structure, the upper and lower sides of the baffle are provided with second threaded holes, the first threaded hole and the second threaded hole are corresponding to each other, the first threaded hole is internally threaded with a bolt, and the second threaded hole is internally threaded with a bolt.

[0013] According to the structure of the carbon felt insulation layer of the sintering furnace, the first locking block corresponds to the second opening, and the second locking block corresponds to the first opening.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with the existing technology, the carbon felt insulation layer structure of this sintering furnace allows for easy replacement of the damaged insulation layer when the insulation layer itself is damaged. Depending on the location of the damage, the operator can remove the blocking device by squeezing the compression block towards the center, or remove the bolts in the corresponding position and pull out the baffle. At this point, the damaged insulation layer can be replaced. The overall operation is relatively simple, and the replacement of small pieces reduces maintenance costs.

[0016] 2. Compared with the prior art, the carbon felt insulation layer structure of this sintering furnace, by setting a first positioning block and a second positioning block, both of which are made of stainless steel, can provide a better and more uniform heating environment for the items to be sintered through the heat reflection effect of the two blocks, in conjunction with the insulation layer body, and can provide better insulation effect for the finished product after sintering.

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Reference Figure 1-5The present invention relates to a carbon felt insulation layer structure for a sintering furnace, comprising a frame 1, with support bases 2 fixedly connected to the lower left and right sides of the frame 1, and first positioning blocks 3 fixedly connected to the upper and lower sides of the frame 1. A first opening 4 is provided below the first positioning block 3, and a second opening 5 is provided above the first positioning block 3. A blocking device 6 is provided in front of the first positioning block 3, and the outer shell of the blocking device 6 is composed of a blocking frame 61. A first slider 62 is slidably connected inside the blocking frame 61. A first locking block 63 is fixedly connected to the upper right side of the first slider 62, corresponding to the second opening 5. A second locking block 64 corresponds to the first opening 4. A second locking block 64 is fixedly connected to the lower right side of the first slider 62. The first locking block 63 penetrates the interior of the blocking frame 61. The first locking block 63 and the blocking frame... 61 is slidably connected. The second locking block 64 passes through the bottom of the blocking frame 61 and is slidably connected to the blocking frame 61. The first slider 62 is fixedly connected to the front of the pressing block 65, which passes through the front of the blocking frame 61 and is slidably connected to the blocking frame 61. The left side of the first slider 62 is fixedly connected to the spring 66, and the other end of the spring 66 is fixedly connected to the second slider 67. The second slider 67 is located inside the blocking frame 61 and is slidably connected to the blocking frame 61. The pressing block 65 is fixedly connected to the front of the second slider 67. The left and right sides of the frame 1 are fixedly connected to the second positioning blocks 7. The front of the second positioning blocks 7 is provided with the first insertion hole 8. The upper left and right sides of the frame 1 are provided with the second insertion holes 9. The four front corners of the frame 1 are provided with the first threaded holes 10.

[0029] The above structure has a certain distance between the middle of the first positioning blocks 3 on the upper and lower sides, which makes the distance a limiting groove, allowing the operator to insert the insulation layer body 11 into it, and the limiting groove limits the insulation layer body 11. Similarly, the middle of the second positioning blocks 7 on the left and right sides has a certain distance, which makes the distance a limiting groove, allowing the operator to insert the insulation layer body 11 into it, and the limiting groove limits the insulation layer body 11.

[0030] By incorporating a first positioning block 3 and a second positioning block 7, both made of stainless steel, the first positioning block 3 and the second positioning block 7 reflect heat during the insulation process. Together with the insulation layer body 11, this device can achieve better insulation performance.

[0031] By incorporating the blocking device 6, when the operator inserts the insulation layer body 11 into the upper and lower limiting grooves, the operator presses the squeezing block 65 towards the center, causing the first locking block 63 and the second locking block 64 to simultaneously enter the blocking frame 61. Then, the blocking frame 61 is inserted into the limiting groove, and the operator releases the device. The spring 66's rebound action causes the first locking block 63 and the second locking block 64 to simultaneously reset. The first locking block 63 corresponds to the second opening 5, and the second locking block 64 corresponds to the first opening 4, allowing the first locking block 63 to insert into the second opening 5 and the second locking block 64 to insert into the first opening 4. At this point, the blocking frame 61 effectively blocks the upper and lower insulation layer bodies 11, preventing them from slipping.

[0032] The insulation layer body 11 is slidably connected to the left and right sides of the first positioning block 3. The insulation layer body 11 is slidably connected to the upper and lower sides of the second positioning block 7. A baffle 13 is slidably connected inside the second insertion hole 9. The baffle 13 has second threaded holes 15 on its upper and lower sides. The first threaded hole 10 corresponds to the second threaded hole 15. A bolt 12 is threaded inside the first threaded hole 10. A bolt 12 is threaded inside the second threaded hole 15. The first insertion hole 8 corresponds to the second insertion hole 9. The baffle 13 passes through the inside of the first insertion hole 8. The baffle 13 is slidably connected to the first insertion hole 8. A pull-out block 14 is fixedly connected above the baffle 13.

[0033] By providing baffles 13, when the operator inserts the baffles 13 on the left and right sides into the second insertion holes 9 on the left and right sides respectively, the baffles 13 on the left and right sides can block the insulation layer body 11 on the left and right sides, preventing the insulation layer body 11 on the left and right sides from slipping off.

[0034] Working principle: The carbon felt insulation layer structure of this sintering furnace utilizes the insulation effect of the insulation layer body 11 itself and the reflective effect of the first positioning block 3 and the second positioning block 7 to achieve a good insulation effect. When the insulation layer body 11 is damaged, only the damaged part of the insulation layer body 11 needs to be replaced.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
