The curing furnace receives the wool felt containing the binder conveyed by the press, and is pressurized and conveyed by the upper and lower conveyor belts, and heated and dried by the hot air circulation system, so that the wool felt is continuously cured to a certain volume density and a certain density. The width and thickness of the wool board are then transported to the next process.
The upper and lower frames of the curing furnace are composed of 6 sections. Each section is aging treated after the welding is completed. The end face of the frame and the mounting surface of the guide rail are all processed by large gantry milling at one time, ensuring the machining accuracy and interchangeability. Sex; each section is connected by pins and bolts, and the external frame is also a detachable structure, which is convenient for transportation and installation.
The material of the chain guide rail is GCr15, the surface is quenched after rough machining, the quenching hardness is HRC55-60, and the quenching depth is 4-6mm. After passing the inspection, it is ground on four sides to ensure the accuracy and parallelism requirements.
The net plates and skeleton materials of the upper and lower chain plates are made of Q345B, which are welded into blanks on special tooling. After aging treatment, drilling and milling are competed on the machining center to ensure the accuracy of the chain plates. After the chain plate processing is completed, every 9 pieces are assembled with the chain. Under the condition of giving the chain a tension of 6000N, check whether the gap between the chain plates and the height of each chain plate are consistent.
The transmission system of the transmission system of the machine, the 3 shaft plates, 0 sprocket sets, one sprocket set, one sprocket set, and one shaft set of each running furnace run through the system to the chain shaft composed of the transmission shaft. Drive it through the system. HI synchronization, the middle system is sandwiched with wool felt, the upper belt is conveyed and the upper frame is lifted. It consists of 26 rock seed machines, reducers, and lifting shafts. The entire drive can be installed to meet the production of various HIP rock wool boards of various thicknesses and thicknesses.
The left and right conveyor chains adopt hydraulic tensioning device, which eliminates the heat of conveying, maintains the same labor service, and ensures the high loan of the conveyor belt.Through the chain detection and control of the lubrication position, the oil injection will be accurate to the grease, which reduces the amount of lubricating oil and improves the grease HI under the condition of lubricating conditions.
There are 3 closed hot air zones inside the curing furnace. Each zone is equipped with an independent air chamber, air duct and hot air circulation system. The air is supplied by the hot air circulation system, and the air temperature and circulation volume can be controlled separately. The outlet of the incinerator is connected to the induced draft fan, and the induced draft fan is connected with the inlet of each air chamber by a pipe, and the outlet of each air chamber is led back to the incinerator by a pipe. In this way, the induced draft fan blows the air heated by the combustion furnace into each air. After the hot air penetrates the wool felt, it is led back to the incinerator for reheating, thus realizing the hot air circulation.
The various pipes of the hot air system of the curing furnace must be wrapped with thermally insulated mineral wool to prevent heat loss.The outer sides of the frame are equipped with heat-insulating wall panels to ensure the temperature in the furnace, reduce heat loss, and improve thermal efficiency.
