Abstract

The utility model provides a furnace body connecting assembly, a furnace body and a graphitization furnace. The furnace body connecting assembly comprises an upper connecting piece, a movable connecting piece, a lower connecting piece and an insulating piece; an inserting opening is formed in the bottom end of the upper connecting piece, and the top end of the movable connecting piece is inserted into the inserting opening; the bottom end of the movable connecting piece is connected with the lower connecting piece, and the insulating piece is arranged in a connecting gap between the movable connecting piece and the lower connecting piece. Due to the fact that the movable connecting piece is inserted into the inserting opening of the upper connecting piece, and the movable connecting piece and the upper connecting piece are not fixedly connected, when the furnace body is heated and expanded to enable the upper shell and the lower shell to generate relative displacement, the movable connecting piece correspondingly generates relative displacement in the inserting opening of the upper connecting piece, and the connecting pieces cannot be damaged by pulling.

Description

Technical Field

[0001] The present application relates to the technical field of graphitization furnaces, and in particular to a furnace body connection assembly, a furnace body, and a graphitization furnace. Background Art

[0002] Graphitized powder is a crucial industrial material, primarily used as a recarburizer in steel and iron metallurgy, as cathode carbon blocks and prebaked anodes for nonferrous metal electrolytic cells, and as diamond products. The most widely used graphitization furnace is a vertical graphite resistance furnace, which heats the raw material using upper and lower graphite blocks. The principle is that after the raw material passes through the electric field between the positive and negative electrodes, the resistance of the material generates heat when electricity is applied, subjecting the material to high-temperature treatment.

[0003] In the related art, a vertical graphitization furnace mainly includes a furnace body and an upper electrode and a lower electrode arranged in the furnace body. The furnace body is a vertical cylindrical structure, with a feed port at the top and a discharge port at the bottom. The inner lining of the furnace body is made of refractory material, and a metal shell is provided on the outside of the inner lining. In order to prevent the upper and lower electrodes from being electrically connected through the metal shell, the metal shell is divided into an upper shell and a lower shell. An insulating sealant is provided between the upper and lower shells. The upper and lower shells are connected by connectors and bolts, and insulating parts are provided on the connectors and bolts to prevent the upper and lower shells from being electrically connected through the connectors.

[0004] However, the vertical graphitization furnace operates at very high temperatures. Thermal expansion and contraction can cause the furnace body to expand, which can easily cause relative displacement between the upper and lower shells. Because the upper and lower shells of the vertical graphitization furnace are fixedly connected to the connectors, relative displacement between the upper and lower shells can easily damage the connectors. Utility Model Content

[0005] The embodiment of the present application provides a furnace body connection assembly, comprising an upper connection member, a movable connection member, a lower connection member, and an insulating member;

[0006] The bottom end of the upper connecting member has a socket, and the top end of the movable connecting member is inserted into the socket;

The movable connector is inserted into the socket of the upper connector to support the upper connector, thereby supporting the upper housing.

[0009] Because the movable connector is inserted into the socket of the upper connector and the two are not fixedly connected, when the furnace body expands due to heat and causes relative displacement between the upper and lower shells, the movable connector also moves relative to the socket of the upper connector, thus preventing the connector from being damaged. At the same time, because the movable connector is insulated from the lower connector by the insulating member, it will not cause electrical conduction between the upper and lower shells.

[0010] In one possible implementation manner, the furnace body connection assembly provided in the embodiment of the present application, the upper connection member includes two side plates, a top plate and a limit plate;

[0011] The top plate is connected to the top ends of the two side plates, and the limiting plate is connected to the side ends of the two side plates;

[0019] In one possible embodiment, the furnace body connection assembly provided in the embodiment of the present application, the side plate is an L-shaped bent plate, the top plate is connected to the horizontal bent portion of the L-shaped bent plate; the limiting plate is connected to the vertical bent portion of the L-shaped bent plate.

[0020] In one possible implementation manner, in the furnace body connection assembly provided in an embodiment of the present application, the base frame is an L-shaped bending frame, and the support plate is connected to the vertical bending portion of the L-shaped bending frame.

[0021] In one possible implementation manner, in the furnace connection assembly provided in an embodiment of the present application, the insulating member is an insulating gasket.

In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0050] Figure 1 is a structural schematic diagram of a furnace connection assembly provided in an embodiment of the present application; Figure 2 is a side view schematic diagram of a furnace connection assembly provided in an embodiment of the present application; Figure 3 1 is an exploded schematic diagram of a furnace connection assembly provided in an embodiment of the present application; Figure 4 Schematic diagram of the furnace provided in an embodiment of the present application. Example

[0051] See also Figure 1-Figure 4 As shown, the embodiment of the present application provides a furnace body connection assembly 100, including an upper connection member 10, a movable connection member 20, a lower connection member 30 and an insulating member 40, wherein:

[0052] The upper connector 10 is used to connect to the upper shell 60 of the furnace body. The bottom end of the upper connector 10 has a socket 10a for inserting the movable connector 20. The top end of the movable connector 20 is inserted into the socket 10a of the upper connector 10, and the bottom end of the movable connector 20 is connected to the lower connector 30. The insulating member 40 is provided between the connecting gap between the movable connector 20 and the lower connector 30. The lower connector 30 is used to connect to the lower shell 70 of the furnace body.

[0053] When the furnace body connection assembly 100 is in use, the upper connector 10 is connected to the upper shell 60, the lower connector 30 is connected to the lower shell 70, and the movable connector 20 is fixedly connected to the lower connector 30 and insulated from the lower connector 30 by the insulating member 40. The movable connector 20 is inserted into the socket 10a of the upper connector 10 to support the upper connector 10, thereby supporting the upper shell 60.

[0054] Because the movable connector 20 is inserted into the socket 10a of the upper connector 10 and the two are not fixedly connected, when the furnace body expands due to heat, causing relative displacement between the upper shell and the lower shell, the movable connector 20 also moves relative to the socket 10a of the upper connector 10, thus preventing the connector from being damaged. At the same time, because the movable connector 20 is insulated from the lower connector 30 by the insulating member 40, electrical conduction between the upper shell 60 and the lower shell 70 will not occur.

[0055] See also Figure 2 and Figure 3 As shown, specifically, one of the structures of the upper connecting member 10 is composed of two side panels 11, a top panel 12 and a limiting plate 13, wherein: the side panel 11 is an L-shaped bending plate, the L-shaped bending plate has a horizontal bending portion and a vertical bending portion, the two L-shaped bending plates are arranged side by side, the top panel 12 is connected to the horizontal bending portion of the two L-shaped bending plates (that is, the top panel 12 is connected to the top end of the two side panels 11), the limiting plate 13 is connected to the vertical bending portion of the two L-shaped bending plates (that is, the limiting plate 13 is connected to the side ends of the two side panels 11), and the side panels 11, the top panel 12 and the limiting plate 13 together enclose to form the socket 10a.

[0056] When the movable connecting member 20 is inserted into the socket 10a of the upper connecting member 10, the top end of the movable connecting member 20 is supported by the top plate 12, the side ends of the movable connecting member 20 are clamped by the two side plates 11, and the outer end of the movable connecting member 20 (the end away from the furnace body) is blocked by the limit plate 13, thereby restricting the movable connecting member 20 in the withdrawal port.

[0057] See also Figure 3As shown, specifically, the movable connecting member 20 includes a base plate 21 and a protrusion 22. The protrusion 22 is connected to the upper end of the base plate 21 and inserted into the socket 10a. The lower connecting member 30 includes a support plate 31 and a base frame 32. The support plate 31 is connected to the top of the base frame 32. The base frame 32 is an L-shaped bending frame. The support plate 31 is connected to the vertical bending portion of the L-shaped bending frame. The insulating member 40 is an insulating pad.

[0058] Bolt holes are provided on the bottom plate 21, support plate 31, and insulating member 40. The insulating member 40 is positioned between the bottom plate 21 and support plate 31, and the center lines of the bolt holes on the bottom plate 21, support plate 31, and insulating member 40 coincide. The bottom plate 21, support plate 31, and insulating member 40 are connected by inserting bolt assemblies 50 into the bolt holes on the bottom plate 21, support plate 31, and insulating member 40.

The upper connection member 10 is connected to the upper shell 60, and the lower connection member 30 is connected to the lower shell 70. Due to the use of the above-mentioned furnace body connection assembly 100, when the furnace body expands due to heat, causing relative displacement between the upper shell and the lower shell, the connection members will not be damaged.
