[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-6 As shown, a centrifugal dryer for granulation of biodegradable materials includes a base 1, an mounting seat 2 fixedly installed on the top of the base 1, a first mounting frame 3 rotatably installed inside the mounting seat 2, a feeding box 4 fixedly installed on the inner wall of the first mounting frame 3, a conveying box 5 rotatably installed on one side of the feeding box 4, and a feeding hopper 6 fixedly connected to the top of the feeding box 4.

[0031] One end of the feed box 4 is provided with a transmission mechanism 7, and the output end of the transmission mechanism 7 is provided with a mixing mechanism 9. One end of the conveying box 5 is provided with a drying mechanism 8. A housing 10 is rotatably installed on the outside of one end of the conveying box 5. An air inlet pipe 11 is fixedly connected to the outside of the housing 10 in an equidistant ring. A conveying screw 15 is fixedly connected inside the conveying box 5, and one end of the conveying screw 15 extends into the inside of the feed box 4.

[0032] In this embodiment, the degradable material particles that need to be dried are added into the feed box 4 through the feed hopper 6. The transmission mechanism 7 operates to make the conveying box 5 rotate. The rotation of the conveying box 5 drives the conveying screw 15 to rotate. The rotation of the conveying screw 15 transports the degradable material particles in the feed box 4 into the conveying box 5 and the drying mechanism 8. Hot air is introduced into the air inlet pipe 11. The hot air fills the interior of the outer shell 10, effectively drying the degradable material particles. Through the cooperation of the transmission mechanism 7, the drying mechanism 8 and the mixing mechanism 9, the mixing efficiency of the degradable material particles is improved, thereby improving the drying efficiency of the degradable material particles.

[0033] In one embodiment, such as Figure 2 and Figure 4 As shown, the transmission mechanism 7 includes a reducer 71 and a first motor 72. Both the reducer 71 and the first motor 72 are fixedly mounted at one end of the feed box 4. The output end of the first motor 72 is connected to the input end of the reducer 71. The output end of the reducer 71 is connected to a first gear 73. A second gear 74 and a third gear 75 are externally meshed with the first gear 73. A fixed frame 76 is rotatably mounted on one end of the third gear 75, and the fixed frame 76 is fixedly mounted to the feed box 4. A transmission shaft 77 is fixedly connected to the other end of the third gear 75. A connecting piece 16 is fixedly connected to one end of the second gear 74, and the connecting piece 16 is fixedly connected to the conveying box 5. One end of the drive shaft 77 passes through the second gear 74 and the connector 16. The first motor 72 drives the reducer 71 to rotate. The reducer 71 rotates, which in turn drives the first gear 73 to rotate. The first gear 73 rotates, which in turn drives the second gear 74 and the third gear 75 to rotate. The second gear 74 rotates, which in turn drives the connector 16 to rotate. The connector 16 drives the conveyor box 5 to rotate. The conveyor box 5 drives the drying mechanism 8 to rotate, so that the degradable material particles are centrifuged inside the drying mechanism 8. The third gear 75 drives the drive shaft 77 to rotate, which in turn drives the mixing mechanism 9 to rotate. The mixing mechanism 9 causes the degradable material particles to tumble and mix inside the drying mechanism 8, so that the degradable material particles can be evenly contacted with the hot air, thus improving the drying efficiency.

[0034] In one embodiment, such as Figure 5 As shown, the drying mechanism 8 includes a drying box 81, which is fixedly connected to one end of the conveying box 5. The inner wall of the drying box 81 is fixedly connected with baffles 82 at equal intervals in a ring. When the drying box 81 rotates, the degradable material particles roll inside. The baffles 82 block the degradable material particles, allowing them to fall from a height and fully contact the hot air, thereby improving the drying efficiency.

[0035] In one embodiment, such as Figure 2 and Figure 3 As shown, the mixing mechanism 9 includes a telescopic sleeve 91, which is keyed to the outside of the drive shaft 77. A telescopic component 92 is slidably installed inside the telescopic sleeve 91. A roller 94 is rotatably installed at the bottom end of the telescopic component 92. A spring 93 is fixedly installed at equal intervals at the top of the telescopic component 92 and inside the telescopic sleeve 91. The rotation of the drive shaft 77 drives the telescopic sleeve 91 to rotate. The telescopic sleeve 91 rotates in the opposite direction to the rotation of the drying chamber 81. The roller 94 contacts the baffle 82 and acts as a guide. The telescopic component 92 moves into the telescopic sleeve 91, and the spring 93 is compressed. When the roller 94 leaves the baffle 82, the spring 93 resets and drives the telescopic component 92 to reset. The telescopic component 92 agitates the degradation material particles, allowing them to fully contact the hot air and improving the drying efficiency.

[0036] In one embodiment, such as Figure 1 and Figure 5 As shown, a housing 12 is fixedly installed at one end of the outer shell 10, and a sealing mechanism 13 is provided on the top of the housing 12. The sealing mechanism 13 is closed during the drying process and is opened when material needs to be discharged.

[0037] In one embodiment, such as Figure 5 As shown, the sealing mechanism 13 includes two fixing plates 131, both of which are fixedly installed on the top of the housing 12. A positive and negative screw 132 is rotatably installed between the two fixing plates 131. A second motor 133 is fixedly installed on one side of each fixing plate 131, and the output end of the second motor 133 is connected to the positive and negative screw 132. An installation groove 134 is provided inside the housing 12. An end cover 135 is slidably installed inside the housing 12 through the installation groove 134, and the end cover 135 is threadedly connected to the positive and negative screw 132. The rotation of the second motor 133 drives the positive and negative screw 132 to rotate, and the rotation of the positive and negative screw 132 drives the two end covers 135 to move together. The two end covers 135 move closer to each other and close. After drying, a material unloading operation is required. The second motor 133 rotates in the opposite direction, driving the positive and negative screw 132 to rotate in the opposite direction. The two end covers 135 move to both ends and open, facilitating the unloading of the dried degradation material particles.

[0038] In one embodiment, such as Figure 1 As shown, an adjustment mechanism 14 is provided on one side of the top of the base 1. The angle of the outer shell 10 can be changed by adjusting the mechanism 14. When one end of the shell 12 moves downward, the dried degradation material particles fall due to gravity, and the feeding operation is completed quickly.

[0039] In one embodiment, such as Figure 6As shown, the adjusting mechanism 14 includes a slide rail 141, which is fixedly installed on the top of the base 1. A groove 142 is formed on the top of the slide rail 141, and a lead screw 143 is rotatably mounted inside the groove 142. A third motor 144 is fixedly installed on the top of the base 1, and the output end of the third motor 144 is connected to the lead screw 143. A moving part 145 is threaded onto the outside of the lead screw 143, and a connecting rod 146 is rotatably mounted on the top of the moving part 145. The top of the 6 is rotatably mounted with a second mounting bracket 147, and the second mounting bracket 147 is fixedly mounted to the outer shell 10. When material needs to be discharged, the third motor 144 drives the lead screw 143 to rotate. The rotation of the lead screw 143 drives the moving part 145 to move. Due to the setting of the connecting rod 146 and the second mounting bracket 147, one end of the outer shell 10 moves downward to facilitate the discharge of the degradable material granules. After the discharge is completed, the third motor 144 rotates in the reverse direction, causing the connecting rod 146 to move in the reverse direction, thereby resetting the outer shell 10.

[0040] The above embodiment discloses a centrifugal dryer for granulating biodegradable materials. The biodegradable material granules to be dried are added to the inside of the feed box 4 through the feed hopper 6. The top of the feed hopper 6 is equipped with a top cover. After feeding, the top cover is placed on the top of the feed hopper 6 to provide a seal. The first motor 72 drives the reducer 71 to rotate. The reducer 71 drives the first gear 73 to rotate. The first gear 73 drives the second gear 74 and the third gear 75 to rotate. The second gear 74 drives the connecting member 16 to rotate. The connecting member 16 drives the conveying box 5 to rotate. The conveying box 5 drives the drying mechanism 8 to rotate, causing the biodegradable material granules to undergo centrifugal processing inside the drying mechanism 8. The third gear 75 drives the drive shaft 77 to rotate. 77 drives the mixing mechanism 9 to rotate, which causes the degradation material particles to tumble and mix inside the drying mechanism 8, so that the degradation material particles can be evenly contacted with the hot air, improving the drying efficiency. After drying, the material needs to be unloaded. The second motor 133 rotates in the reverse direction, which drives the forward and reverse screws 132 to rotate in the reverse direction. The two end caps 135 move to both ends and open. The third motor 144 works to drive the lead screw 143 to rotate. The rotation of the lead screw 143 drives the moving part 145 to move. Due to the setting of the connecting rod 146 and the second mounting bracket 147, one end of the outer shell 10 moves downward, which facilitates the unloading of the degradation material particles. After unloading is completed, the third motor 144 rotates in the reverse direction, which causes the connecting rod 146 to move in the reverse direction, thereby resetting the outer shell 10.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
