Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model will be described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1:

[0022] The following is combined with Figure 1-3 The present embodiment describes an intelligent and environment-friendly production furnace for graphite production, comprising: a production furnace body 1, a feed port 2 and a discharge port 3 are respectively provided on the top wall and the bottom of the side wall of the production furnace body 1, and staggered heating plates 4 are obliquely provided on the inner wall of the production furnace body 1, the heating plates 4 are connected to a heat source, the lowest point of the upper heating plate 4 and the highest point of the lower heating plate 4 are located on the same side, an arc plate 5 is connected to the highest end of the lower heating plate 4 on this side, an anti-overflow plate 6 is connected to the upper end of the arc plate 5, and a material transport blade 7 is provided between the heating plates 4 on this side, the material transport blade 7 is connected to an input shaft 8, the input shaft 8 is rotatably connected to the side wall of the production furnace body 1, the rotation range of the material transport blade 7 intersects with the lowest point of the upper heating plate 4, the lowest point of the upper heating plate 4 is located on the rotation ascending side of the material transport blade 7, and the input shaft 8 is concentric with the arc plate 5;

[0023] The raw material is injected through the feed inlet 2, and slides downward along the inclined surface of the heating plate 4. It is heated by the heat source of the heating plate 4 and begins to be purified and impurities removed. After the raw material slides to the conveying blade 7, the lowest point of the upper heating plate 4 is located on the rotating and ascending side of the conveying blade 7. The raw material enters the upper gap of the conveying blade 7. Under the limiting action of the arc plate 5 and the anti-overflow plate 6, the conveying blade 7 transports the raw material without damage and falls on the lower heating plate 4. Under the flipping action of the conveying blade 7, the positions of the graphite layers are swapped and fall on the lower heating plate 4, which protects the graphite raw material, saves fuel and protects the environment.

[0024] Two adjacent input shafts 8 on the same side are connected by a belt drive 9, and the belt drives 9 on both sides rotate in opposite directions;

[0025] The belt drives 9 on both sides are connected with power of opposite rotation directions, and the transmission system is reasonable.

[0026] The lowest point of the heating plate 4 is connected with a leakproof plate 10, the inner surface of the leakproof plate 10 coincides with the rotation range of the material transport blade 7, and the central angle of the inner arc of the leakproof plate 10 is greater than the central angle of the two adjacent material transport blades 7;

[0027] The provision of the anti-leakage plate 10 can effectively prevent the raw material from falling through the gap between the two material transport blades 7 and causing damage.

[0028] The heating plates 4 are slidably connected to the opposite side walls of the production furnace body 1, and one side of each heating plate 4 is connected to a bracket 11, and the bracket 11 is connected to the vibration mechanism;

[0029] The vibration mechanism can be hydraulic vibration or eccentric vibration. The vibration mechanism drives all heating plates 4 to vibrate simultaneously through the bracket 11, so that the raw materials on the surface of the heating plates 4 will not be stockpiled, and the inclination angle of the heating plates 4 can be smaller, so as to better utilize the limited space in the production furnace.

[0030] The highest point of the top heating plate 4 is in contact with the fixed plate 12 at the same inclination angle, and the lowest point of the lower heating plate 4 is in contact with the fixed plate 2 13 at the same inclination angle. The fixed plate 12 and the fixed plate 2 13 are both connected to the inner wall of the production furnace body 1, and the end of the fixed plate 2 13 is located in the discharge port 3;

[0031] The first fixed plate 12 and the second fixed plate 13 prevent the raw materials from falling and play a guiding role when the materials are fed in and out.

[0032] A gas pipe 14 is provided in parallel at the lower part of the heating plate 4, and an ignition nozzle 15 is provided on the gas pipe 14;

[0033] The gas is injected through the gas pipe 14 , and the ignition nozzle 15 is ignited to directly heat the bottom of the heating plate 4 , which is the best heating method to cooperate with the inclined heating plate 4 .

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
