Description

Technical Field

[0001] The utility model relates to the technical field of bean product production equipment, in particular to a continuous pulp cooker which can fully utilize heat energy. Background Art

[0002] At present, direct steam heating pulp cooking is the most common pulp cooking process. Most of the pulp cooking tanks used for pulp cooking are multi-stage continuous pulp cooking tanks. However, when the slurry is transported between the pulp cooking tanks, some energy will be lost in the pipeline, causing the slurry to cool down. In addition, after the steam pulp cooking is completed, the steam carrying a large amount of heat energy will be directly discharged outside the tank, causing a waste of heat energy and increasing the ambient temperature of the production workshop. This process urgently needs to be improved. Utility Model Content

[0004] By adopting the above technical solution, a waste heat insulation device including a switching joint, a steam supply pipe, several steam distribution pipes, several insulation pipe sleeves, several steam distribution pipes and an exhaust pipe is arranged on the transfer pipeline. Steam with waste heat enters from the steam supply pipe, is transported to several insulation pipe sleeves in turn, and the outside of the transfer pipeline is insulated. Finally, the steam is discharged from the exhaust pipe. This can effectively avoid the temperature loss of the slurry during the transfer process, and at the same time, make full use of the waste heat of the steam.

The preheated water is then used as part of the source water for the steam generator, which can further fully utilize the waste heat of the steam.

[0009] A further configuration of the present invention is that a spray-proof protective sleeve is provided at one end of the exhaust pipe.

[0010] With the above technical solution, since one end of the exhaust pipe is provided with a blowout-proof protective sleeve, the air in the steam preheating water tank can be buffered when discharged, thus avoiding the generation of huge noise. BRIEF DESCRIPTION OF THE DRAWINGS
