Background

In the rock wool production, need behind the collection cotton to pleat and get into the solidification link again, it can rock wool fibre arrange more closely knit to pleat the link, and rock wool after pleating sends into the curing oven and carries out high temperature solidification and suppression into the rock wool goods. A large amount of hot air can be generated and emitted near the curing oven, and the roller close to the inlet of the curing oven needs to be cooled by circulating water to ensure that the surface of the roller is not stained with cotton, so that the surface of the rock wool felt is smooth and flat.

In the cooling link in the prior art, an integrated large-volume water box is adopted, a movable joint is laterally arranged on the water box and is used for receiving cooling water, but in actual production, the movable joint of the water box is close to a roller and a curing furnace, so that the heat exchange is more, the movable joint is particularly easy to damage and leaks, sometimes the leaked water can be split on folded rock wool, and when the rock wool containing water enters a curing link, the curing uniformity of the rock wool can be influenced; and the water box of integral type is because longer a section distance all is shared by water box volume, can not install the roller bearing of transporting, and when rock wool edge extension after pleating was more, easy jam, even artifical mediation or the roller bearing at the back impel the mediation forward by oneself in service, all produced the influence to the uniform velocity that the rock wool marchd, further influences the solidification.

The cooling water of the water box is generally circulating water, which is circulated to an outdoor water tower to be cooled and then enters a circulating system, and the waste gas generated in the curing link contains thermosetting binder.

If the water storage of the water box can be utilized, the organic matters in the waste gas generated in the curing link can be well removed.

SUMMERY OF THE UTILITY MODEL
