Description

Technical Field

[0001] The utility model relates to the technical field of steam recovery, in particular to a steam guide recovery device. Background Art

[0002] Impregnation technology is an effective measure to solve casting leakage. It uses vacuum pressure to penetrate the impregnation liquid into the looseness, pores and other defects of the casting. After solidification, it fills the micropores of the casting, which can solve the leakage and achieve the effect of sealing and pressure bearing. In the organic vacuum impregnation process, a heat curing tank is required to solidify the impregnation liquid in the micropores of the workpiece product to achieve the effect of gelling reinforcement. The temperature in the curing tank is usually between 80-95℃. Due to the high water temperature, when the tank cover is opened after the curing is completed, a large amount of hot steam will be released, which will not only pollute the workshop, but also easily scald the operator. Therefore, the impregnation process must solve the problem of hot steam in the curing tank.

[0003] There are also some steam recovery related technologies in the prior art, such as the Chinese invention patent with application number CN201310270845.8, entitled A Steam Recovery Device for a Hot Water Curing Tank, which discloses a steam recovery device for a curing tank, which uses a water pump to pump water in a water tank into a steam circulation box, and the circulating water flows through a perforated plate to the bottom of the perforated plate to cool the steam in the steam circulation channel below, thereby reducing or even achieving heatless steam emission, protecting the on-site environment and the safety of production equipment, and protecting operators from steam burns. However, the overall size of the device is relatively large, and it is arranged directly above the water tank of the curing tank, which will affect the sealing, use and placement of the workpiece of the curing tank.
