However, the graphite purifying equipment arranged in the vertical direction continuously processes the graphite material entering from the top of the purifying furnace by using the resistance heating device, and because the graphite material is continuously accumulated from top to bottom, the density of the graphite material at the lower part is far higher than that of the graphite material at the upper part, the graphite material is easy to agglomerate and unevenly distribute under the action of the upper pressure, and when the graphite purifying equipment is continuously processed in a large batch, the problems of low resistance heating efficiency, inconsistent graphite purification, easy agglomeration, easy material blockage and the like exist.

The boat-free natural graphite purifying process does not disclose the structures of a specific preheating treatment device and a vertical induction heating continuous purifying furnace, and adopts a mode that natural graphite raw materials are directly placed in a hearth to implement continuous purification, so that the problems that the graphite raw materials are continuously accumulated from top to bottom, the graphite raw materials at the center of the hearth and the graphite raw materials at the periphery of the hearth, the graphite raw materials at the lower part of the hearth and the graphite raw materials at the upper part of the hearth are not purified uniformly, the graphite raw materials are heated and distributed uniformly, the graphite purification is not uniform, the agglomeration is easy, the blockage is easy, and the material flowing speed is not controlled well.

Compared with the prior art, the invention has the following beneficial effects:

the working principle of the invention is as follows: the method comprises the steps of firstly loading materials to be purified in a movable heating body, and vertically superposing the heating body (the heating body in the invention adopts graphite crucibles with the same structure and the same size) on a supporting plate through a manual or automatic loading device (the invention adopts a tail gas preheating type grabbing and feeding device to carry out loading operation), wherein the supporting plate is fixedly connected with a supporting rod at the bottom and a first lifting hydraulic cylinder. Through the self-weight and the lifting operation of the first lifting hydraulic cylinder, the heating body sequentially passes through a high-temperature heating cavity, a heat preservation cavity and a cooling cavity in the vertical high-temperature furnace body from top to bottom, and materials in the heating body are respectively subjected to induction heating purification, heat preservation and cooling. When the material is to be discharged, the first lifting hydraulic cylinder moves downwards, so that the first heating body (counted from bottom to top) positioned on the upper part of the supporting plate passes through the cylindrical discharge hole to reach the lower part of the bottom of the vertical high-temperature furnace body. When the supporting plate reaches the position which is parallel and level with the left discharging rack and the right discharging rack, the first lifting hydraulic cylinder stops moving, and the second horizontal hydraulic cylinder and the third horizontal hydraulic cylinder which are arranged at the bottom of the top plate of the operating platform move to drive the left holding circle and the right holding circle to clamp a second heating body (counting from bottom to top) on the upper part of the first heating body from two sides. The first horizontal hydraulic cylinder acts, a piston rod of the first horizontal hydraulic cylinder moves leftwards to drive the fork-shaped pushing frame to move leftwards, and the heating body at the bottom of the supporting plate is pushed leftwards to the left discharging rack, so that discharging of the heating body is realized. Then a piston rod of the first horizontal hydraulic cylinder moves rightwards to drive the fork-shaped pushing frame to return to the initial position; the first lifting hydraulic cylinder moves upwards to enable the supporting plate to lift and prop against the heating body clamped by the left holding circle and the right holding circle, and the piston rods of the second horizontal hydraulic cylinder and the third horizontal hydraulic cylinder return to enable the left holding circle and the right holding circle to be loosened, so that a feeding and discharging cycle is completed.

The invention adopts a vertical high-temperature continuous purification furnace, and the structure and the technical effect of the vertical high-temperature continuous purification furnace are different from those of the existing horizontal continuous purification furnace. The existing horizontal continuous purification furnace generally adopts a plurality of transport boats, the materials are placed in the transport boats, and the transport boats are continuously sent into the purification furnace through a transport device for purification. The existing horizontal continuous purifying furnace needs to open a hearth or continuously open and close a furnace door, so that a large amount of heat is lost, the heat efficiency is low, and the continuous difference of heating when a transport boat enters and exits the hearth is inconvenient for continuous heating, purification, heat preservation and cooling. The purification speed is slow, and the production cycle is long. The invention adopts the vertical high-temperature furnace body without covers at two ends, so that the cylindrical feed port and the cylindrical discharge port of the vertical high-temperature furnace body are matched with the heating body, and simultaneously, the electromagnetic induction heating coil is adopted to carry out induction heating on the heating body and the material by utilizing the property that the heating body (graphite crucible) is an inductor and has the same property with the material (graphite material), so that the heat utilization rate is greatly improved, the heating speed is high, no impurities are brought in, the heating is more uniform, the material purification quality is higher, and the heating is vertical and continuous with the prior art. The invention adopts a plurality of heating elements to load materials in batches in a separated manner, and the materials sequentially pass through the high-temperature heating cavity, the heat preservation cavity and the cooling cavity in the vertical high-temperature furnace body from top to bottom to carry out continuous heating purification, heat preservation and cooling, and also better utilizes the characteristics of downward movement of gravity and upward diffusion of heat, thereby improving the heat utilization rate and saving energy. Because the materials are loaded in batches and separately, the materials cannot be continuously stacked from top to bottom, and the caking situation cannot occur. The batch separated loading is more convenient to receive the heat of the induction heating of the heating body, so that the heating is more uniform and the purification effect is better. The invention is also different from the existing vertical continuous graphite purification device, and solves the problems that the graphite material of the existing vertical continuous graphite purification device is easy to agglomerate and unevenly distribute under the action of upper pressure, and the problems of low resistance heating efficiency, inconsistent graphite purification, easy agglomeration, easy material blockage and the like exist in large-scale continuous treatment.

In addition, the tail gas preheating type grabbing and feeding device is adopted, the tail gas is compressed and fed into the interlayer in the interlayer bin by the second air pump, when the feeding operation is needed, the clamping cylinder bodies in the left grabbing unit and the right grabbing unit drive the clamping plates to clamp the heating body from the left side and the right side, meanwhile, the first electromagnetic valve is opened, the central spray pipe sprays the tail gas with waste heat into the heating body to preheat the heating body, the heat energy of the tail gas is better utilized, the heat energy efficiency is further improved, and the energy is saved.

The invention provides the idea of moving the heating element, realizes the continuous operation production mode of the medium/high frequency kiln, improves the energy efficiency utilization rate and the product purification quality, and reduces the labor intensity of workers.
