Description

Technical Field

[0001] The utility model relates to the field of box-type furnaces, in particular to a weighable box-type furnace. Background Art

[0002] A box furnace is a supporting device for heating. It is also called a muffle furnace. It is simple to operate, easy to maintain, and equipped with a controllable chimney behind the furnace. The box furnace is a heating furnace with a box-shaped furnace chamber. The products are fixed during the entire heating process of heating, heat preservation and cooling. The feeding and discharging are carried out through a single door or slot. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of box furnaces.

[0003] The existing box-type furnace has certain disadvantages when in use. First, the existing box-type furnace has a relatively simple structure, and the conventionally designed box-type furnace does not have a weighing function, which is not conducive to people's use. In addition, the box-type furnace cools down slowly after use, which can easily cause burns, bringing certain adverse effects to the actual use process. For this reason, we propose a weighable box-type furnace. Utility Model Content

[0004] Technical problem solved: In view of the shortcomings of the prior art, the utility model provides a weighable box furnace, in which a SiSiC square beam is placed at both ends of the roller, and a weighing sensor is set at the bottom of the square beam. After the material enters the furnace, the furnace door is closed and the weighing sensor is reset to zero until sintering is completed. The weight change curve of the material during sintering can be generated and exported, and the weighing accuracy can reach 0.2‰, which can effectively solve the problems in the background technology.

[0005] Technical solution: To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a weighable box-type furnace, comprising a box-type furnace main body, a square beam is positioned on the side of the box-type furnace main body, a roller is arranged on the square beam, a weighing sensor is installed at the bottom of the square beam, a sagger is arranged at the upper end of the roller located inside the box-type furnace main body, a temperature-control thermocouple and a lower heating rod are installed at the lower position inside the box-type furnace main body, a bottom air intake preheating chamber and a bottom air intake interlayer are installed at the bottom of the box-type furnace main body, an upper heating rod is installed at the upper position inside the box-type furnace main body, side air intake holes are opened on the side of the sagger, and a furnace door is arranged on the side of the box-type furnace main body.

[0006] Preferably, the roller is limited on the square beam and rotates, the sagger moves to the inner position of the box-type furnace body through the roller, and the weighing sensor monitors the weight of the sagger.

[0007] Preferably, the interior of the box-type furnace body is heated by an upper heating rod, a lower heating rod and a temperature-controlled thermocouple, and the bottom of the box-type furnace body is preheated by a bottom air intake preheating cavity and a bottom air intake interlayer.

[0008] Preferably, the square beam is engaged with the weighing sensor through a slot, and the square beam and the weighing sensor are integrated on the outside of the box-type furnace body.

[0009] Preferably, air is taken in at the bottom air intake interlayer and is finally output from the top of the box-type furnace body through the air intake preheating chamber.

[0010] Beneficial effects: Compared with the prior art, the utility model provides a weighable box-type furnace, which has the following beneficial effects: the general loss on burnout rate of the sintered material in this weighable box-type furnace is 25%, that is, the material will be burned into gaseous state and volatilized during the sintering process, and the weight will slowly decrease. If you want to know how much of the material volatilizes at different temperatures, you must know the real-time weight of the material during the sintering process. To achieve this goal, a weighable box-type furnace is designed, and a SiSiC square beam is placed at both ends of the roller, and a weighing sensor is set at the bottom of the square beam. After the material enters the furnace, the furnace door is closed, and the weighing sensor is reset to zero until the sintering is completed. The weight change curve of the material during the sintering period can be generated and exported, and the weighing accuracy can reach 0.2‰. The entire box-type furnace has a simple structure and is easy to operate, and the effect of use is better than that of the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS
