[0027] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0029] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0030] An embodiment of a feeding device for producing graphite in a silicon carbide furnace core, such as Figures 1 to 7 As shown, it includes a crushing box 1 for processing raw materials for silicon carbide furnace core graphite production and a discharge box 4 that can control the discharge speed. The top of the crushing box 1 is provided with a feed hopper 2 for convenient feeding, and a semicircular material collection trough 16 is provided below the feed hopper 2. The setting of the material collection trough 16 can concentrate the raw materials put in. Two meshing crushing rollers 11 are provided inside the crushing box 1. The ends of the two crushing rollers 11 are rotatably connected to the inner wall of the crushing box 1. A drive motor 8 is screwed to the side wall of the crushing box 1. The output shaft of the drive motor 8 passes through the crushing box 1 and is connected to the crushing roller 11. Because the crushing roller 11 is located above the material collection trough 16, the setting of the material collection trough 16 can put the raw materials to be processed into the working range of the crushing roller 11, thereby controlling the rotation of the output shaft of the drive motor 8, driving the connected crushing roller 11 to rotate, and completing the crushing processing of the raw materials.

[0031] An inclined triangular block is welded in the middle of the crushing box 1. The function of the triangular block is similar to that of the material collecting trough 16, which is intended to concentrate the rapid accumulation of crushed raw materials. A linear motor 19 is provided below the triangular block and is fixed to the inner wall of the crushing box 1. The linear motor 19 is provided with a dust-proof structure to prevent the crushed raw materials from affecting the movement of the linear motor 19. The same sieve plate 15 is fixed to the moving parts of the two linear motors 19. A screen 17 is embedded in the interior of the sieve plate 15, and the staggered arrangement of the two linear motors 19 makes the connected sieve plate 15 tilted inside the crushing box 1, which is convenient for accelerating the screening of raw materials and for quickly extracting large-particle raw materials. A discharge plate 18 connected to the sieve plate 15 is provided on one side of the screen 17. Because the side wall of the crushing box 1 is provided with an inclined discharge hopper 10, the discharge hopper 10 extends through the crushing box 1 into its interior, and the discharge hopper 10 is located below the discharge plate 18, which is convenient for screening out the rejected large-particle raw materials.

[0032] A mixing box 9 is welded to the bottom of the crushing box 1, and a rotating motor 12 is fixed to the bottom of the mixing box 9. The output shaft of the rotating motor 12 passes through the mixing box 9 and is fixed to one end of the rotating shaft 13 through a coupling. A spiral stirring paddle 14 is welded on the outer peripheral side of the rotating shaft 13. The stirring paddle 14 is arranged to stir the raw materials entering the mixing box 9 after crushing under the drive of the rotating motor 12, so that all kinds of raw materials are fully mixed, which is convenient for improving the production rate of graphite in the silicon carbide furnace core. The inner bottom wall of the mixing box 9 is provided with a material channel inclined for gathering materials. One side of the mixing box 9 is screwed to an auger 3 for conveying raw materials. The auger 3 is located at the lowest point of the material channel, so that it is convenient to accelerate the extraction of the mixed raw materials in the mixing box 9 under the action of the material channel and the auger 3. The other end of the auger 3 is fixed to the side wall of the discharge box 4, and a rectangular support foot 7 is welded at the bottom of the discharge box 4 to transport the raw materials to the inside of the discharge box 4.

[0033] For the convenience of observation, a transparent window 5 is embedded in the top of the discharge box 4, and a fixed plate 6 is welded on one side of the discharge box 4. The fixed plate 6 is for hanging an escalator during inspection. In order to control the discharge speed of the raw materials inside the discharge box 4, an electric push rod 21 is fixed on one side of the discharge box 4. The moving part of the electric push rod 21 passes through the discharge box 4 and is connected with the moving plate 22. The moving plate 22 is slidingly connected to the discharge pipe arranged inside the discharge box 4. By controlling the connection area between the moving plate 22 and the connecting pipe, the discharge speed of the temporal part of the discharge box 4 is controlled. In order to maintain the stability of the movement of the moving plate 22, two round rods 20 with smooth outer circumferences are welded on one side of the moving plate 22. The round rods 20 are symmetrically arranged relative to the electric push rods 21, and the round rods 20 are slidingly connected to the discharge box 4, which improves the structural stability of the device.

[0034] The auger 3, drive motor 8, rotary motor 12, linear motor 19 and electric push rod 21 are all conventional instruments. Their working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] How it works

[0036] The feeding device for producing silicon carbide furnace core graphite, when using the device, the raw material of sintering silicon carbide furnace core graphite is put into the crushing box 1 through the feed hopper 2, the output shaft of the drive motor 8 is started to rotate, driving the connected crushing roller 11 to rotate, crushing the raw material, and then synchronously controlling the movement of the moving part of the linear motor 19 installed in the crushing box 1 to drive the sieve plate 15 connected to the moving part of the linear motor 19 to move, and cooperating with the installed screen 17 to crush the crushed raw material, and the screened raw material enters the welded mixing box 9 through the channel. At this time, the output shaft of the driving rotary motor 12 is rotated, driving the connected rotating shaft 13 to rotate, because a spiral stirring paddle 14 is welded on the outer peripheral side of the rotating shaft 13, thereby completing the stirring and mixing of the crushed and screened raw materials;

[0037] Finally, the auger 3 is controlled to work, and the raw materials accumulated at the bottom of the material channel after mixing are transported to the inside of the discharge box 4. Then the moving part of the electric push rod 21 is controlled to move, driving the connecting moving plate 22 to move inside the discharge box 4 to complete the control of the discharge speed.
