Description

Technical Field

[0001] This utility model relates to the field of graphite electrode technology, specifically to a calcination apparatus for the production of graphite electrodes. Background Technology

[0002] In the production process of graphite electrodes, calcination is one of the key heat treatment processes. Its function is to remove volatiles from the electrode blank and improve the mechanical strength and electrical conductivity of the material through high temperature. However, existing graphite electrode calcination equipment directly places the blank into the calcination furnace for high-temperature calcination. However, the existing equipment uses fixed heating elements, which result in uneven heat distribution, low heat transfer efficiency, long calcination time, and even inconsistent heating of the electrode blank, affecting product quality and easily causing local over-burning or insufficient calcination. Therefore, a more efficient calcination device for graphite electrode production is needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a high-efficiency calcination device for the production of graphite electrodes.

The material rack is slidably set inside the roasting furnace and can be pulled out by opening the cover plate, and the electrode blanks are placed on the material rack. The reciprocating roasting mechanism includes a heating barrel and a reciprocating drive mechanism. Heating wires are evenly laid on the inner wall of the heating barrel. After the heating barrel is set around the material rack, it reciprocates at a certain angle under the drive of the reciprocating drive mechanism to roast the electrode blanks on the material rack. The cooling mechanism is installed on the calcining furnace and is used to cool and unload the calcined electrode blanks.

[0005] As an improvement, the roasting furnace is equipped with a pair of sliding rods located inside the heating barrel, and the material rack is slidably positioned between the two sliding rods.

[0006] As an improvement, an arc-shaped guide plate is set at the top center of the roasting furnace, and the heating barrel is slidably connected to the arc-shaped guide plate. The reciprocating drive mechanism is set at the bottom of the roasting furnace, which pushes the heating barrel to rotate back and forth at a certain angle.

[0007] As an improvement, the reciprocating drive mechanism includes a rack, a reciprocating drive rod, and a hydraulic telescopic rod; A reciprocating drive rod is slidably installed at the bottom of the roasting furnace. One end of the hydraulic telescopic rod is fixed to the side wall of the roasting furnace, and the other end is fixedly connected to the reciprocating drive rod. A rack is provided on the top surface of the reciprocating drive rod, and a toothed groove that meshes with the rack is fixedly provided on the outer wall of the heating barrel.

[0008] As an improvement, a one-way exhaust valve is connected to the top of the roasting furnace, and the cooling mechanism includes a refrigeration fan. A pair of cooling fans are provided, which are installed on the side wall and cover plate of the roasting furnace respectively. The two cooling fans are set opposite each other and blow air into the material rack.

[0009] As an improvement, a transparent window was also installed on the roasting furnace.

[0010] The advantages of this utility model compared with the prior art are as follows: 1. The heating barrel is arranged around the material rack and is driven to rotate by a reciprocating drive mechanism to achieve dynamic heating, which effectively improves the heating uniformity and avoids the problems of local over-burning or insufficient roasting; 2.
