[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model discloses a continuous centrifugal dryer adopting differential screw pushing, comprising a base 1 and a stirring wheel feeding device 2 fixedly connected to the top of the base 1, the top and bottom of the stirring wheel feeding device 2 are respectively fixedly connected to the feed hopper 3 and the centrifugal drying device 4, the centrifugal drying device 4 comprises a first bearing seat 5.1 and a first flange seat 4.2 fixedly connected to the front end of the differential screw shaft 4.1 in sequence, and a second flange seat 4.3 connected to the rear end of the differential screw shaft 4.1 in sequence, a first drying transmission wheel 4.4, a second bearing seat 5.2 and a screw shaft transmission wheel 4.5, a material distribution port 6 and a pushing spiral piece 7 are fixedly arranged in the middle of the differential screw shaft 4.1, a drying barrel 8 is installed above the differential screw shaft 4.1, and a discharge port 9 is fixedly arranged in the area between the rear end of the differential screw shaft 4.1 and the second flange seat 4.3.

[0022] In order to further optimize the above technical solution, parallel and symmetrical support structures 1.1 are fixed on both sides of the bottom of the base 1 to stabilize the overall structure and withstand the various forces and vibrations generated during the operation of the dryer, ensuring stable operation of the equipment. The motor support platform 1.2 is fixedly welded to the tail end of the base 1 to support the motor 10. At the same time, the base 1 must have sufficient strength and rigidity to prevent deformation or damage. Preferably, common high-strength materials include stainless steel, alloy steel, and cast iron, and the specific material is selected by the user.

[0023] In order to further optimize the above technical solution, the agitator feed device 2 is fixedly arranged at the head end position above the base 1. Furthermore, the agitator feed device 2 includes a driving device 2.1 fixedly installed at the left end and a feeding device 2.3 connected by a chain 2.2. Preferably, the driving device 2.1 is a servo motor, and the feeding device 2.3 is a cylinder with a built-in cavity for the installation of the agitator. Its working principle is to drive the chain to rotate through the motor to drive the agitator in the feeding device, thereby achieving the working purpose of the agitator feed device 2 to push the material into the differential screw shaft 4.1.

[0024] To further optimize the above technical solution, the feed hopper 3 is fixedly arranged above the impeller feed device 2 and is the primary interface for materials to enter the equipment. It is responsible for receiving the materials to be processed. Furthermore, the feed hopper 3 is hollowly connected to the impeller feed device 2. At the same time, the feed hopper 3 is a square structure with a large opening and a small inlet, ensuring that the materials can smoothly enter the impeller feed device 2 and avoid clogging or scattering of the materials during the feeding process.

[0025] In order to further optimize the above technical solution, the differential screw shaft 4.1 in the centrifugal drying device 4 is nested and connected to the agitator feeding device 2. Specifically, the material is poured from the feed hopper 3, and the agitator feeding device 2 pushes the material into the differential screw shaft 4.1, and the differential screw shaft 4.1 runs through the centrifugal drying device 4. Specifically, the front end of the differential screw shaft 4.1 is fixedly connected to the first bearing seat 5.1 and the first flange seat 4.2, and the rear end of the differential screw shaft 4.1 is fixedly connected to the screw shaft transmission wheel 4.5, the second flange seat 4.3, the first drying transmission wheel 4.4, and the second bearing seat 5.2. The screw shaft transmission wheel 4.5 is connected to the first driving wheel 10.1 on the motor 10 through a belt. Its working principle is to drive the screw shaft transmission wheel 4.5 to move through the transmission belt of the motor 10, thereby driving the rotation of the differential screw shaft 4.1. Similarly, the first spin-drying transmission wheel 4.4 and the second spin-drying transmission wheel 11 are connected to the second driving wheel 10.2 on the motor 10 through a belt. Specifically, the second driving wheel 10.2 on the motor 10 is connected to the second spin-drying transmission wheel 11, and the other end of the second spin-drying transmission wheel 11 is synchronously connected to the first spin-drying transmission wheel 4.4. Its working principle is to drive the second spin-drying transmission wheel 11 to rotate through the transmission belt of the motor 10, thereby synchronously driving the first spin-drying transmission wheel 4.4 to rotate, and then driving the spin-drying barrel 8 installed above the differential screw shaft 4.1 to rotate. Finally, the spin-drying barrel 8 and the differential screw shaft 4.1 that rotate at the same time produce a speed difference, and the spiral blade 7 fixed on the differential screw shaft 4.1 pushes the material toward the discharge port 9, thereby completing the material drying process.

[0026] Belt drives utilize friction between the belt and pulleys to transmit motion and power. Specifically, when the belt is tightly fitted around two pulleys (one on the driving pulley and the other on the driven pulley), tension creates friction between them. As the driving pulley rotates, friction drives the belt, which in turn drives the driven pulley, thus transmitting power. Due to the belt's softness and elasticity, belt drives can mitigate load impact, reduce vibration and noise, and ensure a smoother transmission process.

[0027] In order to further optimize the above technical solution, a material distribution port 6 is fixedly provided in the middle of the differential screw shaft 4.1 and is located in the front end area of the middle of the differential screw shaft 4.1 for materials to enter the drying barrel 8.

[0028] In order to further optimize the above technical solution, the head and tail ends of the drying barrel 8 are respectively mounted on the differential screw shaft 4.1 through flange seats.

[0029] The specific implementation process is as follows: the material is poured into the feed hopper 3, the agitator feeding device 2 pushes the material into the differential screw shaft 4.1, and enters the drying barrel 8 from the distribution port 6 by centrifugal force. The drying barrel 8 receives power from the motor 10 under the drive of the first drying transmission wheels 4.4 and 11. At the same time, the power of the motor 10 is transmitted to the differential screw shaft 4.1 through the differential screw shaft transmission wheel 4.5. Because the drying barrel 8 and the differential screw shaft 4.1 rotating at the same time have a speed difference, the spiral blade 7 on the differential screw shaft 4.1 pushes the material toward the discharge port 9 to complete the material drying.

[0030] The utility model discloses a continuous centrifugal dryer adopting differential screw pushing, which continuously pushes the material through the differential screw device, thereby avoiding the problems of material accumulation and uneven drying that may exist in traditional dryers, greatly improving the drying efficiency, and ensuring that the material can pass through the drying process continuously and stably.

[0031] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
