Technical Field

If the heating material is liquid, the liquid will easily flow into the heating cavity through the damaged part and contact with the external port or the heating resistor wire, causing the risk of short circuit and fire. After the heating tube is deformed, the heating material inside it is easy to be heated unevenly, and some materials cannot meet the use conditions of the next process.

[0020] Specifically, a heating tube 8 is fixedly installed inside the furnace body 1, and a heat-insulating layer 9 is fixedly connected to the inner wall of the furnace body 1. The heat-insulating layer 9 can effectively prevent heat loss. The inside of the heat-insulating layer 9 and the outside of the heating tube 8 form a heating chamber 10. A heating resistance wire 11 is fixedly installed on the outside of the heating tube 8. Both the front and rear sections of the heating chamber 10 are provided with lateral supports 12. The outside of the lateral support 12 is fixedly connected to the inside of the heat-insulating layer 9. The inside of the lateral support 12 is fixedly connected to the outside of the heating tube 8. A mounting hole 13 is penetrated through the right rear end of the lateral support 12. A plurality of connecting cross bars 14 are fixedly connected to the inside and outside of the mounting hole 13. The ends of the connecting cross bars 14 are fixedly connected to the outside of the heating tube 8. The support 12 and the connecting cross bar 14 can effectively improve the strength and deformation resistance of the furnace body 1 in the front-to-back direction. A number of temperature sensors 15 are fixedly installed on the inner rear side of the heating tube 8. A number of support rods 16 are fixedly connected on the left and right sides of the heating tube 8. The support rods 16 can effectively improve the strength and deformation resistance of the furnace body 1 in the left and right directions. The left and right ends of adjacent support rods 16 are fixedly connected by a number of connecting vertical rods 17. Fixed rods 18 are fixedly connected to the left and right ends of the lower side of the heating tube 8. The upper ends of the two fixed rods 18 are fixedly connected to the lower side of the support rods 16. The connecting vertical rods 17 and the fixed rods 18 can effectively improve the vertical strength and deformation resistance of the furnace body 1.

[0021] Working principle: The switch of the first electromagnetic valve 4 and the second electromagnetic valve 7 is controlled by the operation panel 5 to transport and discharge materials. After the material to be heated is transported to the inside of the heating tube 8 through the feed pipe 6, the heating resistor 11 begins to increase the temperature inside the heating chamber 10 and transfers the heat to the inside of the heating tube 8 to heat the material. The temperature sensor 15 monitors the temperature inside the heating tube 8 in real time and transmits it to the operation panel 5. When the pressure inside the heating tube 8 changes significantly and the generated pressure acts on the inner wall of the heating tube 8, the lateral support 12 and the connecting cross bar 14 will resist the force in the front and rear directions, thereby improving the stability and deformation resistance of the furnace body 1. The support rod 16 will resist the force in the left and right directions, and the connecting vertical rod 17 and the fixing rod 18 will resist the force in the vertical direction, thereby improving the strength and deformation resistance of the furnace body 1 as a whole.
