Description

Technical Field

[0001] The utility model relates to the technical field of rock wool board production, in particular to a fiber recovery device for a rock wool board production line. Background Art

[0002] Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. It was successfully tested in June 1981. Rock wool board is a new type of thermal insulation, flame retardant and sound-absorbing material; rock wool board is an artificial inorganic fiber processed by high-temperature melting. It has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility. Rock wool board may have problems such as unqualified cutting and production defects on the production line. Therefore, it is necessary to crush the waste and defective products generated on the production line and then recycle them to avoid waste of resources, save energy and protect the environment. Therefore, it is necessary to use crushing equipment to crush the board during the recycling operation.

[0003] Patent No. CN202222051669.6 discloses a fiber recovery device for a rock wool board production line. By providing a crushing component, starting a drive motor, and driving two crushing knives to rotate relative to each other, the block rock wool material can be quickly crushed to facilitate subsequent recycling work. The rock wool material is discharged through the No. 2 discharge port and transferred and transported through the No. 2 conveyor. The overall stability is high, so that the equipment can perform continuous shredding and crushing work, thereby improving the overall processing efficiency. By providing a dust reduction component, a protective cover is assembled on the crushing chamber for sealing to prevent the waste debris and smoke generated during the crushing process from spreading over a large area. Filter cotton is used for adsorption and finally discharged through the exhaust pipe for purification to avoid the generation of a large amount of smoke in the processing environment. The water source is transferred and transported by means of a water supply pipe and a branch pipe to deliver the water source to the filter cotton to ensure that the moisture in the filter cotton can quickly absorb the smoke and avoid the problem of smoke floating.

When pulverizing, the protective cover must be fully opened when adding feed to the crushing chamber. When adding feeding, a lot of dust in the crushing chamber is raised out, which pollutes the environment. Utility Model Content
