Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a vertical high-temperature furnace plate heating structure. Background Art

[0002] Graphite is a high-energy crystalline carbon material. Due to its unique structure and the characteristics of electrical conductivity, thermal conductivity, lubrication, high temperature resistance, and stable chemical properties, it has a high application value in high-performance materials. It is widely used in metallurgy, machinery, environmental protection, chemical industry, refractory, electronics, medicine, military industry, aerospace and other fields, and has become an indispensable non-metallic material for the development of modern industry and high, new and cutting-edge technologies. Chlorination roasting is a relatively commonly used purification method. It uses the melting and boiling points of impurity oxides to purify graphite. It has the advantages of energy saving, high recovery rate, and good purification effect. Chlorination roasting is to add a certain amount of reducing agent to graphite, and then introduce chlorine at a certain temperature and a certain atmosphere to allow chlorine to react chemically with impurities in graphite. The impurities in graphite are eventually transformed into metal chlorides and complexes in the gas phase or condensed phase, and separated from graphite, thereby achieving the purpose of obtaining high-purity graphite.

[0003] However, the vertical high-temperature furnace plate heater in the prior art has a complex structure, is easily damaged, and is difficult to assemble or replace accessories, which reduces the service life of the heater and increases the cost of graphite purification. At the same time, the internal heating structure is single and cannot ensure internal heating uniformity, which also reduces the efficiency and stability of graphite purification. In view of the shortcomings of the prior art, the utility model provides a vertical high-temperature furnace plate heating structure to solve the above problems. Utility Model Content

At the same time, the graphite electrode adopts an external threaded rod structure to increase the abutment surface with the electrode corner connector to ensure connection stability. The external thread is more conducive to increasing the size, improving the strength of the parts, and increasing the service life of the parts. The temperature uniformity is better guaranteed by setting the long heater and the short heater at an interval, thereby improving the efficiency and stability of graphite purification.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a vertical high-temperature furnace plate heating structure, including a long heater, a plurality of groups of the long heaters are distributed in a ring array, and a short heater is connected between every two groups of the long heaters;

[0006] The long heater is fixedly connected with an electrode angle connector, and the electrode angle connector is fixedly connected with a graphite electrode;

[0007] The graphite electrode is provided with an external threaded rod, the electrode angle connector is provided with a supporting step, and the supporting step is fixedly connected with a nut seat threadedly connected to the external threaded rod.

[0008] Preferably, the electrode angle connector includes a positive connector, a left connector and a right connector.

[0009] Preferably, a lower corner connector is fixedly connected between the long heater and the short heater.

[0010] Preferably, the long heater and the short heater are respectively provided with a first fixing hole and a third fixing hole corresponding to the position of the lower corner connecting piece, and the lower corner connecting piece is fixed to the long heater and the short heater through a graphite nut.

[0011] Preferably, the long heater is provided with a second fixing hole corresponding to the position of the electrode angle connector.

[0012] The utility model discloses a vertical high-temperature furnace plate heating structure, which has the following beneficial effects:

[0013] The plate heating structure of the vertical high-temperature furnace uses parts with the same structure to facilitate replacement and assembly, thereby improving production efficiency. At the same time, the graphite electrode adopts an external threaded rod structure to increase the abutment surface with the electrode corner connector to ensure connection stability. The external thread is more conducive to increasing the size, improving the strength of the parts, and increasing the service life of the parts.
