[0033] Fixed furnace body 1 one side is fixed with suction tube 4, and the end of suction tube 4 in fixed furnace body 1 extends to one side of rotary furnace bottom 2;

[0034] Suction tube 4 front end is fixed with guide tube piece 5, and guide tube piece 5 is movably embedded in the recess of rotary furnace bottom 2, and guide tube piece 5 is the cylinder with one side opening, and the opening of guide tube piece 5 faces the opposite direction of the rotation of rotary furnace bottom 2, and the opening lower end of guide tube piece 5 is slidably attached to the inner bottom surface of the recess of rotary furnace bottom 2;

[0035] The end of guide tube piece 5 away from suction tube 4 forms a closed end, and the end of guide tube piece 5 close to suction tube 4 is fixed and communicated with suction tube 4 through arc-shaped fixed half ring 6, and the lower end of arc-shaped fixed half ring 6 is in sliding contact with the upper end of rotary furnace bottom 2.

[0036] Based on the above structure, by setting guide tube piece 5 at the end of suction tube 4, and making guide tube piece 5 as a whole into the recess of rotary furnace bottom 2, when the mica sheet that is calcined is moved to the opening of guide tube piece 5 by rotary furnace bottom 2, the mica sheet enters guide tube piece 5 from the opening, and then is sucked out under the negative pressure adsorption of suction tube 4, to complete the discharging operation of the mica sheet, and the suction tube 4 is fixedly installed, so it can be used with the corresponding negative pressure adsorption mechanism, without setting an additional driving mechanism, which simplifies the overall structure of the equipment, and at the same time, the setting of guide tube piece 5 can ensure that the suction tube 4 covers the entire cross section of the recess of rotary furnace bottom 2, ensuring the efficiency of discharging, in addition, it can also ensure the overall sealing of the equipment, avoid the loss of internal heat, and save energy.

[0037] Further, the lower end of the opening of guide tube piece 5 forms a material starting slope 53, which is inclinedly arranged, and the material starting slope 53 intercepts the mica sheet on rotary furnace bottom 2 and shovels the mica sheet upward, so that the mica sheet is more easily entered into guide tube piece 5.

[0038] Further, the material guiding cylinder 5 comprises a fixed inner cylinder 51 and a movable outer cylinder 52, and a material guiding slope 53 is formed at the lower end of the fixed inner cylinder 51 and the movable outer cylinder 52 to form a continuous slope structure. The fixed inner cylinder 51 is fixed to the end of the material suction pipe 4 through the arc-shaped fixed half ring 6, and the movable outer cylinder 52 is slidably sleeved outside the fixed inner cylinder 51 and is elastically connected to the fixed inner cylinder 51 through an elastic structure.

The inner diameter of the end of the movable outer cylinder 52 away from the material suction pipe 4 is the same as the inner diameter of the fixed inner cylinder 51, so that the fixed inner cylinder 51 and the movable outer cylinder 52 can form a unified whole to ensure the effectiveness of the discharge of the mica sheet.

[0044] Further, the distance between the end of the movable outer cylinder 52 close to the material suction pipe 4 and the end of the material suction pipe 4 is greater than the distance between the end of the fixed inner cylinder 51 close to the material suction pipe 4 and the end of the material suction pipe 4.
