Description

Technical Field

[0001] The utility model relates to the technical field of cupolas, in particular to a rock wool cupola with an improved structure. Background Art

[0002] Rock wool is an inorganic fiber material made from basalt and other stones. This material is made through a high-temperature melting process. The cupola is an important equipment in the rock wool manufacturing industry. It is used to melt the raw materials of rock wool. The cupola includes a furnace body and a furnace top. The furnace body is located at the lower part of the furnace top. A feed port is provided on the furnace top, and the ore raw materials are thrown into the cupola through the feed port.

[0003] In order to increase the melting amount, an excessive amount of ore raw materials are often poured in at one time for melting, which leads to low melting efficiency and incomplete melting. In order to solve this problem, it is necessary to prevent the ore raw materials from accumulating inside the furnace body. For example, patent No. CN209877607U discloses a rock wool cupola with a built-in flip structure, which drives the ore raw materials to move by flipping blades to avoid internal rock accumulation, increase the heating area, and improve the heating efficiency. However, the flip blades are connected to the shaft body with ordinary bolts, which are prone to loosening when impacted by the ore raw materials, affecting normal use over time.
