Description

Technical Field

[0001] This utility model relates to the field of spinning box calcination technology, and specifically discloses a detachable spinning box insulation box. Background Technology

[0002] In the chemical fiber production process, the spinning box, as the core equipment for distributing high-temperature melt, is prone to leaving behind polymer carbonized coke deposits after long-term operation, requiring periodic calcination to remove them. Traditional insulation boxes are mostly integral welded structures, which require breaking the insulation layer and disassembling the entire box during calcination.

[0003] Currently available spinning box components primarily connect the spinning box and the insulation box by welding. The main problems with this method are: 1. When the spinning box needs to be calcined, the spinning box and the insulation box cannot be separated, but the insulation box cannot be calcined. 2. Forcibly separating the insulation box and the spinning box can easily cause deformation or damage to the shape of the insulation box, posing safety hazards and affecting the spinning quality. Therefore, a detachable spinning box / insulation box is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a detachable spinning box insulation box. The insulation box and the spinning box are relatively independent and connected by bolts. Disassembly will not damage the insulation box, ensuring that the insulation cotton will not leak out, avoiding safety hazards, and ensuring the spinning quality.

[0005] This utility model is implemented as follows: a detachable spinning box insulation box includes a lower insulation box connector, a spinning box is arranged inside the lower insulation box connector, a flange-type mating surface is provided on the upper end face of the lower insulation box connector, a first set of bolt holes are equidistantly arranged on the flange-type mating surface, and an upper insulation box connector is detachably connected to the flange-type mating surface by fastening bolts.

[0006] Spinning box supports are symmetrically welded on both the left and right sides of the spinning box. Insulation box supports are installed through both the left and right sides of the outer wall of the lower insulation box connector. A second set of bolt holes is opened through both ends of the insulation box support. The second set of bolt holes located inside the lower insulation box connector is detachably connected to the spinning box support by bolts.

[0007] As a preferred embodiment of the detachable spinning box insulation box of this utility model, the extended end of the insulation box bracket is detachably connected to an external bracket through a second set of bolt holes and fastening bolts.

[0008] As a preferred embodiment of the detachable spinning box insulation box of this utility model, the bottom of the upper insulation box assembly is provided with a third set of bolt holes corresponding to the first set of bolt holes.

[0009] As a preferred embodiment of the detachable spinning box insulation box of this utility model, the inner walls of both the upper insulation box connector and the lower insulation box connector are provided with insulation cotton.
