[0020] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0021] As shown in Figures 1-6 An embodiment of the present application provides a sintering furnace partition device, which comprises a sintering furnace 1, a track 2 laid along the length direction at the bottom of the sintering furnace 1, and a transfer trolley 3 arranged on the track 2. The top surface of the transfer trolley 3 is fixed with a detachably connected upper partition plate 5, and the bottom surface of the transfer trolley 3 is fixed with a detachably connected lower partition plate 6. The upper partition plate 5 and the lower partition plate 6 are spliced into a sintering furnace partition plate. The sintering furnace partition plate made of refractory material partitions the sintering furnace 1 along the cross section of the sintering furnace 1.

[0022] The upper partition plate 5 and the lower partition plate 6 are made of refractory material and can be fixed at the upper and lower ends of the transfer trolley 3 respectively. The edges of the upper partition plate 5 and the lower partition plate 6 are adapted to the shape of the inner wall of the sintering furnace 1. A plurality of transfer trolleys 3 are sequentially parked on the track 2 outside the sintering furnace 1.

[0023] In use, the workpieces to be sintered are sent into the sintering furnace 1 through some of the transfer trolleys 3. Then, the sintering furnace partition plate is installed on the other empty transfer trolleys 3. The transfer trolleys 3 with the sintering furnace partition plate are sent into the sintering furnace 1 along the track 2 to partition the cross section of the sintering furnace 1. After the areas in the sintering furnace 1 where the workpieces are placed are partitioned, the workpieces are sintered by local electric heating of the areas where the workpieces are placed through the electric control system, and the other areas are not heated.

[0024] In the embodiment, the sintering furnace partition plate spliced by the upper partition plate 5 and the lower partition plate 6 is installed on the transfer trolley 3, and then the transfer trolley 3 with the sintering furnace partition plate is moved into the sintering furnace 1 to partition the cross section of the sintering furnace 1.

[0025] The workpieces to be sintered are moved into the sintering furnace 1, and the sintering furnace 1 is partitioned by the sintering furnace partition plate according to the number and size of the workpieces. Then, the workpieces are sintered by electric heating of the areas in the sintering furnace 1 where the workpieces are placed. The reduced sintering space improves the energy utilization efficiency and the heating speed of the sintering furnace. The local heating mode also reduces the use of energy, saves energy, and reduces the use cost of the sintering equipment.

[0026] In a possible implementation, a plurality of through holes 4 are vertically arranged on the transfer trolley 3, the lower end of the upper part 5 of the partition plate and the upper end of the lower part 6 of the partition plate are respectively fixed with plug rods 7 which are plugged into the through holes 4, and the upper part 5 of the partition plate and the lower part 6 of the partition plate are fixed with connecting ears 8 at corresponding positions, and the upper part 5 of the partition plate and the lower part 6 of the partition plate are fixed by bolt connection from top to bottom of the transfer trolley 3 through the connecting ears 8.

[0027] The through holes 4 are used to plug the plug rods 7 to install the upper part 5 of the partition plate and the lower part 6 of the partition plate on the transfer trolley 3, and the upper part 5 of the partition plate and the lower part 6 of the partition plate are fixed by bolt connection through the connecting ears 8, which is convenient for disassembly and assembly. The sintering furnace partition plate can be installed on any transfer trolley 3 to divide the sintering furnace 1, and is flexible and convenient to use.

[0028] In a possible implementation, the lower end of the lower part 6 of the partition plate is provided with a groove 9 matched with the track 2, so that the lower part 6 of the partition plate can extend downward to the track 2.

[0029] The groove 9 leaves space for the track 2, which can reduce the gap between the lower end of the lower part 6 of the partition plate and the bottom surface in the sintering furnace 1, and further improve the heat insulation effect.

[0030] In a possible implementation, a plurality of spliced baffle plates 10 are fixed on the edges of the upper part 5 of the partition plate and the lower part 6 of the partition plate, and the baffle plates 10 are made of flexible refractory material.

[0031] The spliced baffle plates 10 can shield the edges of the upper part 5 of the partition plate and the lower part 6 of the partition plate. Moreover, in the process of moving the upper part 5 of the partition plate and the lower part 6 of the partition plate with the transfer trolley 3, the flexible baffle plates 10 can bend and bypass the fixed components on the inner wall of the sintering furnace 1.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
