Description

Technical Field

[0001] The utility model relates to the field of box-type furnace charge cooling, in particular to a box-type furnace top cover charge cooling device. Background Art

[0002] When a box-type furnace is used to produce graphite materials, it is necessary to use a box-type furnace to heat the internal negative electrode material to 2000 degrees Celsius to achieve graphitization. After graphitization, the power needs to be turned off to cool down. After the graphite material inside the box-type furnace is cooled down, it is taken out of the furnace and then produced next time.

[0003] The existing box-type furnace cooling mainly adopts natural cooling or air cooling, which takes a long time and affects the production efficiency of the box-type furnace. Therefore, it is necessary to study a box-type furnace top cover charge cooling device to solve the above problem. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a furnace charge cooling device for a box-type furnace top cover.

[0005] The utility model is realized through the following technical solutions:

[0006] A box-type furnace top cover charge cooling device comprises a fence-type water inlet pipe assembly and a corresponding water return pipe assembly at the bottom. The water inlet pipe assembly and the water return pipe assembly are connected and fixed by a plurality of longitudinal connecting pipes. The lower part of the return pipe assembly is connected and fixed with a cooling insert that can be inserted into the box-type furnace for cooling.

[0007] Further optionally, the water inlet pipe assembly and the water return pipe assembly include a water inlet frame pipeline and a cooling frame pipe that are opposite to each other up and down, and the inner sides of the water inlet frame pipeline and the cooling frame pipe are laterally connected and fixed with a plurality of opposite connecting transverse pipes and cooling transverse pipes.

[0008] Further optionally, a plurality of connecting pipes are evenly distributed between the opposite water inlet frame pipes, cooling frame pipes and connecting transverse pipes, and cooling transverse pipes.

[0009] Further optionally, a plurality of cooling inserts and a plurality of connecting tubes are arranged vertically opposite to each other, and a flow guide tube extending toward the lower end of the interior of the cooling insert is connected to the lower outlet end of the connecting tube.

[0010] Further optionally, the bottom of the cooling tube is arranged with an oblique opening.

[0011] Further optionally, the water inlet frame pipeline and the cooling frame pipe are respectively connected with a water inlet and a water outlet.

[0012] Compared with the existing technology, the beneficial effect of the utility model is that the utility model enters the cooling insert through the water inlet pipe assembly to cool the graphite charge on the top of the box-type furnace, and then discharges it step by step from the return pipe assembly for circulating cooling after cooling. The cooling effect is better, and the cooling time is shorter than that of natural cooling with air cooling, which greatly improves the production efficiency of the box-type furnace.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0018] like Figure 1 As shown, a box-type furnace top cover charge cooling device includes a fence-type water inlet pipe assembly and a corresponding return pipe assembly at the bottom. The water inlet pipe assembly and the return pipe assembly are connected and fixed by a plurality of longitudinal connecting pipes 5. The lower part of the return pipe assembly is connected and fixed with a cooling insert 6 that can be inserted into the box-type furnace 11 for cooling.

[0019] like Figure 1 As shown, the water inlet pipe assembly and the water return pipe assembly include a water inlet frame pipe 1 and a cooling frame pipe 2 that are opposite to each other in the upper and lower parts. The inner sides of the water inlet frame pipe 1 and the cooling frame pipe 2 are laterally connected and fixed with a plurality of opposite connecting transverse pipes 3 and cooling transverse pipes 4.

[0020] like Figure 1 As shown, a plurality of connecting pipes 5 are evenly distributed between the water inlet frame pipe 1, the cooling frame pipe 2, the connecting transverse pipe 3 and the cooling transverse pipe 4 that are facing each other.

[0021] like Figure 1 , 2 As shown, a plurality of cooling inserts 6 and a plurality of connecting tubes 5 are arranged vertically opposite to each other, and the lower outlet end of the connecting tube 5 is connected to a guide tube 8 extending toward the lower end of the cooling insert 6. The diameter of the guide tube 8 is smaller than that of the cooling insert 6. The cooling water of the guide tube 8 is first introduced into the bottom of the cooling insert 6 to pre-cool the inside of the graphite charge 12.

[0022] like Figure 2 As shown, the bottom of the cooling insert 6 is provided with an oblique opening 7 to facilitate the cooling insert 6 to be inserted into the graphite charge 12 .

[0023] like Figure 2 As shown, the water inlet frame pipeline 1 and the cooling frame pipe 2 are respectively connected with a water inlet 9 and a water outlet 10.

[0024] The implementation principle of a box-type furnace top cover charge cooling device in the present application embodiment is:

[0025] When the box-type furnace 11 is cooled after graphitization, the furnace top cover 13 of the box-type furnace 11 is first removed, and then the device is transferred to the top of the corresponding box-type furnace 11, and the device is pressed down (the loader bucket can be used to press down both sides synchronously) so that the lower cooling insert 6 is inserted into the graphite charge 12 of the box-type furnace 11, so that the cooling frame tube 2 is in contact with the graphite charge 12 on the furnace top (such as Figure 3 As shown), then connect the water inlet 9 to the cooling water pipe and the water outlet 10 to the return water pipe;

[0026] After the connection is completed, the cooling water in the cooling water pool is pressurized by the pressure pump and enters the water inlet frame pipe 1 and the connecting cross pipe 3 of the water inlet pipe assembly along the water inlet 9, and then enters the return pipe assembly from the connecting pipe 5 and is directly transported to the bottom of the cooling insert 6 along the guide pipe 8 connected at the bottom, flows upward from the bottom of the cooling insert 6 and fills the cooling frame pipe 2 and the cooling cross pipe 4 of the return pipe assembly, and finally flows into the cooling water pool from the water outlet 10 and the return pipe for cooling and circulation;

[0027] During cooling in this way, the bottom of the cooling tube 6, i.e., the graphite charge 12, is firstly entered for rapid internal cooling. After cooling, the upper part of the graphite charge 12 is circulated and cooled from the return pipe assembly. In this way, the cooling is performed step by step from the inside of the graphite charge 12 to the outside (the temperature inside the graphite charge 12 is higher than the temperature outside when the furnace top cover 13 at the top is removed). The cooling effect is better, and the cooling time is shorter than that of natural cooling with air cooling, which greatly improves the production efficiency of the box furnace 11.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
