Technical Field

[0001] The utility model relates to the technical field of papermaking, in particular to a waste heat recovery device for papermaking equipment. Background Art

[0002] In the papermaking process, the main purpose of drying is to remove moisture from the pressed paper sheets, while improving the strength of the paper and increasing the smoothness of the paper. During the drying process, the dryness of the paper sheets generally needs to be controlled within a certain range, and the residual moisture must be evaporated in the drying section of the paper machine, usually supplied in the form of steam.

[0003] In the prior art, in the process of papermaking drying, a waste heat recovery device is used to recycle the waste heat generated in the drying process. Generally, hot steam is transported through a pipeline. Since the drying gas carries harmful substances in the process of completing the drying operation, these harmful impurities will be transported through the pipeline, and part of them will adhere to the inner wall of the pipeline. If the staff does not clean it for a long time, the harmful impurities on the inner wall of the pipeline will mix with the harmful impurities in the hot steam, which will cause this part of the hot steam to carry too many harmful impurities. If it is discharged to the outside world at one time, it will directly affect the air environment and cause air pollution. Utility Model Content

The one-time discharge to the outside world will directly affect the air environment and cause air pollution. In order to achieve the above purpose, the present utility model provides the following technical solutions: A waste heat recovery device for papermaking equipment, including a temperature-locking sleeve, the inner cavity of the temperature-locking sleeve is fixedly sleeved with a conveying pipe, one side of the conveying pipe is provided with an auxiliary component, the auxiliary component includes a ring sleeve, the ring sleeve is fixedly sleeved on one side of the outer side of the conveying pipe, the inner cavity of the ring sleeve is fixedly connected with an internal thread, the inner cavity of the ring sleeve is threadedly connected with a sealing plug, the outer side of the sealing plug is fixedly connected with an external thread, and the middle part of the inner cavity of the conveying pipe is fixedly connected with a fan.

[0005] Further preferably, a connecting pipe is fixedly connected to the top of the conveying pipe, and a connecting assembly is provided on one side of the connecting pipe, and the connecting assembly includes a connecting pipe.

The hot steam can enter the interior of the connecting tube 501 through the corrugated folded tube 503, and then can enter the interior of the connecting tube 4 through the connecting tube 501, and then enter the interior of the conveying tube 2. By starting the fan 305, the hot steam can be quickly discharged into the interior of the heat storage tank 601. An exhaust pipe is fixedly connected to the upper side of the rear surface of the heat storage tank 601, and the hot steam can be discharged through the exhaust pipe. When the hot steam is discharged into the interior of the heat storage tank 601, the transmission motor 602 is started to drive the transmission rod 603 rotates.
