By starting the second motor, the first rotating rod connected to the output end thereof rotates, and the conveying paddles on the periphery of the first rotating rod evenly convey the materials. At the same time, the material particles are decomposed during the conveying process, and the materials are heated during the conveying process by the heating rods to improve the drying efficiency. The conveyed materials reach the interior of the drying chamber. By starting the corresponding first motor, the second rotating rod connected to the output end rotates counterclockwise. Since the outer surfaces of the driving gear and the driven gear are meshed with each other, the counterclockwise rotation of the second rotating rod can drive the corresponding third rotating rod to rotate clockwise. The multiple groups of bearings on the peripheries of the second rotating rod and the third rotating rod ensure their stable rotation on the inner wall of the transmission chamber.

[0017] 2.

The material holding coatings effectively grab the materials. The materials first rise with the corresponding L-shaped plates and then slide down, increasing the contact area between the drying air and the materials and improving the drying effect. The vibration generated by the motor is effectively damped by the dampers and springs between the pressure-bearing seat and the shock-absorbing seat, reducing the operating noise and increasing the service life of the equipment.

Four groups of pressure-bearing seats 6 are symmetrically arranged on the outer surface of the bottom of the support base 2. And between the bottom outer surface of each group of pressure-bearing seats 6 and the inner surface of the top of the corresponding support base 2, two groups of dampers 18 and springs 19 are fixedly connected, and the spring 19 is located outside the corresponding damper 18. On the outer surface of the top of the support base 2, a fixing sleeve 3, a transmission chamber 9, and a drying chamber 13 are sequentially arranged.

A fixing sleeve 3 is arranged on the outer surface of the top of the transmission chamber 9. A second motor 7 is limited and fixed between the corresponding fixing sleeves 3. The output end of the second motor 7 is provided with a first rotating rod 23. A feeding chamber 10 is arranged on the periphery of the first rotating rod 23. A heating rod 11 is arranged on the inner surface of the top of the feeding chamber 10. Specifically, through the cooperation of the above structures, the uniformity of material drying is ensured. The rotational movement of the paddles enables the materials to be fully mixed and dispersed inside the dryer, avoiding local overheating or over-wetting.

[0027] Refer to Figures 1 - 6, a buffer chamber 8 is provided on the periphery of the feeding chamber 10. An inlet 24 is provided on the outer surface of the top of the buffer chamber 8. The bottom output end of the feeding chamber 10 on the side far from the inlet 24 communicates with the top of the drying chamber 13. A conveying paddle 4 is arranged around the first rotating rod 23. Specifically, by starting the second motor 7, the first rotating rod 23 connected to its output end rotates, and the conveying paddle 4 around the first rotating rod 23 evenly conveys the material, and at the same time decomposes the material particles during the conveying process. An observation window 12 is provided on the top of the drying chamber 13. The inside of the inlet 24 includes a driven gear 902, a bearing 903 and a driving gear 904. A driving gear 904 is arranged around the second rotating rod 901. A third rotating rod 905 is arranged on the front side of the second rotating rod 901. A driven gear 902 is arranged around the third rotating rod 905. Specifically, by starting the corresponding first motor 5, the second rotating rod 901 connected to its output end rotates counterclockwise, and multiple groups of bearings 903 around the second rotating rod 901 and the third rotating rod 905 ensure its stable rotation on the inner wall of the transmission chamber 9.

[0028] Referring to Figures 1 - 6 , the outer surfaces of the driven gear 902 and the driving gear 904 are meshed with each other. A set of bearings 903 are arranged between the outer surfaces of the third rotating rod 905 and the second rotating rod 901 and the left and right inner walls of the transmission chamber 9. The inner surface of each set of bearings 903 is fixedly connected to the third rotating rod 905 and the second rotating rod 901, and the outer surface of each set of bearings 903 is fixedly connected to the left and right inner walls of the corresponding transmission chamber 9. Specifically, since the outer surfaces of the driving gear 904 and the driven gear 902 are meshed with each other, the counterclockwise rotation of the second rotating rod 901 can drive the corresponding third rotating rod 905 to rotate clockwise. A number of pairs of hollow paddles 20 are arranged around the third rotating rod 905 and the second rotating rod 901. Two groups of L-shaped plates 21 are arranged on the outer surface of the right side of each group of hollow paddles 20. Specifically, the counterclockwise rotation of the second rotating rod 901 and the clockwise rotation of the third rotating rod 905 ensure the corresponding rotation of the L-shaped plates 21 and the material-containing coatings 22 arranged on their right outer surfaces.

[0029] Referring to Figures 1 - 6 , a set of material-containing coatings 22 are arranged clockwise on the end face of each group of L-shaped plates 21 around the third rotating rod 905, and a set of material-containing coatings 22 are arranged counterclockwise on the end face of each group of L-shaped plates 21 around the second rotating rod 901. Specifically, the material-containing coatings 22 effectively grab the material, and the material first rises with the corresponding L-shaped plates 21 and then slides down, increasing the contact area between the drying air and the material and improving the drying effect.

[0030] The implementation principle of an embodiment of the high-efficiency hollow paddle dryer of the present application is as follows:

[0031] When using a hollow paddle dryer to dry material workpieces, the material is evenly poured into the interior of the buffer chamber 8 through the feed inlet 24. By starting the second motor 7, the first rotating rod 23 connected to its output end rotates. The first rotating rod 23 drives the conveying paddles 4 around it to evenly convey the material. At the same time, the material particles are decomposed during the conveying process. The heating rod 11 heats the material during the conveying process to improve the drying efficiency. The conveyed material reaches the interior of the drying chamber 13. By starting the corresponding first motor 5, the second rotating rod 901 connected to its output end rotates counterclockwise. Since the outer surfaces of the driving gear 904 and the driven gear 902 are meshed with each other, the counterclockwise rotation of the second rotating rod 901 can drive the corresponding third rotating rod 905 to rotate clockwise. The multiple groups of bearings 903 around the second rotating rod 901 and the third rotating rod 905 ensure their stable rotation on the inner wall of the transmission chamber 9.

[0032] On the other hand, the counterclockwise rotation of the second rotating rod 901 and the clockwise rotation of the third rotating rod 905 ensure the corresponding rotation of the L-shaped plate 21 and the material holding coating 22 provided on their right outer surfaces. The material holding coating 22 effectively grabs the material. The material first rises with the corresponding L-shaped plate 21 and then slides down, increasing the contact area between the drying air and the material and improving the drying effect. The vibration generated by the motor is effectively dampened by the damper 18 and the spring 19 between the pressure bearing seat 6 and the shock absorber seat 15, reducing the operating noise and increasing the service life of the equipment.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
