Description

Technical Field

[0002] An intelligent muffle furnace is a smart industrial resistance furnace that integrates a muffle furnace and temperature controller, utilizes a microprocessor as its control center, and features high energy efficiency and precise temperature control. It is widely used in heat treatment, sintering, heating, thermal analysis, and scientific research experiments in fields such as materials science, metallurgy, ceramics, and chemical engineering. Its primary function is to heat and sinter samples at high temperatures, and it offers high-temperature stability, uniform heating, and excellent thermal efficiency. Muffle furnaces are commonly used for heat treatment, sintering, degassing, annealing, and calcining of samples, providing a stable high-temperature environment to meet the needs of various experiments and processes.

[0003] In the prior art, since the intelligent muffle furnace can provide a stable high-temperature environment, and heats evenly and has high thermal efficiency, the intelligent muffle furnace is often used in the process of flotation agent research and development.

[0026] It should be noted that the present invention is an intelligent muffle furnace with a protective structure. After the sample is heated on the grid storage plate 5 in the heating chamber 4, the furnace body 2 is opened to take the sample in the heating chamber 4. Under the control of the controller 1, the drive motor 17 installed on the rear end wall of the fixing seat 12 will be turned on. The drive motor 17 will drive the output end to drive the rotating rod 16 at the rear end of the screw 15 to rotate in the bearing 14 installed in the mounting hole 13 opened at the front end of the fixing seat 12. The rotating rod 16 will drive the screw 15 to rotate, so that the connecting plate 20 moves backward along the screw 15 through the screw hole 21 opened on the front end wall, and the connecting plate 20 will drive the movable cross plate 18 between the symmetrical fixing bars 10 installed on the top surface of the furnace body 2. When sliding, the T-shaped sliders 19 installed at both ends of the moving cross plate 18 will slide in the T-shaped slide grooves 11 opened on the inner side walls of the fixed strips 10 until the horizontal parts of the L-shaped material-picking rods 25 symmetrical on the bottom surface of the moving cross plate 18 are placed between the symmetrical side plates 8 installed at the front ends of the grid storage plates 5 in the heating chamber 4. At this time, under the control of the controller 1, the electric push rods 24 installed on the outer side walls of the mounting seats 23 installed on both sides of the top surface of the moving cross plate 18 will be turned on. The electric push rods 24 will drive the output end to pull the L-shaped material-picking rods 25 outward, and the vertical part of the L-shaped material-picking rods 25 will move in the sliding slots 22 opened on the top surface of the moving cross plate 18 until the horizontal part of the L-shaped material-picking rods 25 is installed on the outer side walls of the horizontal parts. The block 26 is inserted into the block 9 provided on the side wall of the side plate 8. Finally, the driving motor 17 is turned on again under the control of the controller 1 to flip its output end, so that the connecting plate 20 moves forward along the screw 15 driven by the rotating rod 16 through the screw hole 21. The connecting plate 20 will drive the movable cross plate 18 to move synchronously, and the L-shaped material picking rod 25 on the top surface of the movable cross plate 18 will move with the movement of the movable cross plate 18. In the process of the L-shaped material picking rod 25 moving forward, the grid storage plate 5 can be moved out of the heating chamber 4 through the block 26, and the two side parts of the grid storage plate 5 are moved out of the slot 7 until the grid storage plate 5 is completely moved out of the heating chamber 4, so that the sample on the top surface of the grid storage plate 5 is After the sample is left to cool, it can be removed. Next time when the sample is processed, the sample can be placed directly on the grid storage plate 5, and then the controller 1 controls the material removal protection mechanism 6 to make the grid storage plate 5 enter the heating chamber 4. After the restriction on the grid storage plate 5 is released and the material removal protection mechanism 6 returns to its original position, the furnace door 3 is closed to prepare for the next material removal operation, thereby achieving the purpose of automatically taking out the heated sample in the heating chamber 4 and automatically placing the sample. There is no need for the user to manually take out the sample, which avoids the problem of the user being burned by high temperature, and plays the role of material removal protection, thereby not only improving the safety of the use of the intelligent muffle furnace, but also improving the degree of intelligence and facilitating sample removal.
