The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 8 As shown, the biomass energy raw material drying device of the present invention includes a drying mechanism 1, a dewatering mechanism 2, a pressing mechanism 3 and a feeding mechanism 4. The feeding mechanism 4 is connected to the dewatering mechanism 2, and is used to transport the crushed firewood to the dewatering mechanism 2 (the feeding mechanism 4 can transport the crushed firewood to the dewatering mechanism 2 by wind power, and the feeding mechanism 4 is a prior art, which will not be described in detail here). The dewatering mechanism 2 is connected to the drying mechanism 1, and is used to dewater the crushed firewood, thereby reducing the water content in the firewood. The pressing mechanism 3 is connected to the feeding mechanism 4, and is used to press down the firewood in the dewatering mechanism 2 to enhance the dewatering effect on the firewood. The drying mechanism 1 is used to dry the dewatered firewood (the drying mechanism 1 is a prior art, which will not be described in detail here).

[0031] like Figures 1 to 6As shown, the water removal mechanism 2 includes a shell 21, a driving member 22, a water-removing member 23, a guide ring 1 24, a drainage portion 25, a discharge portion 26, a shielding portion 1 27 and a shielding portion 28. The shell 21 is connected to the drying mechanism 1, the driving member 22 is installed in the shell 21, and three water-removing members 23 are provided. The three water-removing members 23 are all installed on the driving member 22 (in other embodiments, the number of water-removing members 23 can also be more than one).

The driving member 22 can drive the three water-removing members 23 to rotate in a circle, and at the same time drive the three water-removing members 23 to rotate along their own axes respectively, so as to remove water from the firewood and collect it by the shell 21, thereby reducing the water content of the firewood, thereby reducing the energy consumption of the drying mechanism 1 and improving the drying efficiency of the firewood.

[0032] The guide ring 1 24 is connected to the shell 21, the bottom of the water-throwing member 23 contacts the guide ring 1 24, and a groove 241 is provided on the guide ring 1 24. When the water-throwing member 23 moves to the groove 241, the water-throwing member 23 can be opened to discharge the firewood after the water is thrown out. The drainage part 25 is connected to the shell 21 and is used to discharge the water in the shell 21. The discharge part 26 is connected to the bottom of the shell 21 and is used to discharge the firewood after the water is thrown out into the drying mechanism 1. The shielding part 1 27 and the shielding part 28 are both connected to the inner bottom wall of the shell 21. The shielding part 1 27 and the shielding part 28 are both located at the guide ring 1.

The driving source 221 is connected to the inner top wall of the shell 21, the driving source 221 is a motor with an output shaft facing the motor, the connecting arm 222 is connected to the output shaft of the driving source 221, the sealing ring 223 and the connecting ring 224 are both connected to the connecting arm 222, and the sealing ring 223 is located above the connecting ring 224, the water-throwing member 23 is rotatably connected to the sealing ring 223 and the connecting ring 224, the sealing ring 223 and the upper surface of the water-throwing member 23 are located on the same horizontal plane, and can block the feeding mechanism 4 after the water-throwing member 23 is separated from the feeding mechanism 4.

[0034] The fixing ring 225 is connected to the inner wall of the shell 21, the connecting ring 224 is located on the inner side of the fixing ring 225, the bottom of the blocking ring 223 is in contact with the top of the fixing ring 225, the output shaft of the driving source 221, the blocking ring 223, the connecting ring 224 and the fixing ring 225 are coaxially arranged, the tooth plate 226 is connected to the inner wall of the fixing ring 225, the tooth plate 226 is arc-shaped, the tooth plate 226 is located between the blocking ring 223 and the connecting ring 224, and the tooth plate 226 is staggered with the groove 241 of the guide ring 24, and the number of tooth rings 227 is three, and the three tooth rings 227 are respectively connected to the three water-throwing parts 23.

[0035] When the driving source 221 drives the connecting arm 222 to rotate, the sealing ring 223 and the connecting ring 224 are driven to rotate through the connecting arm 222, and the water-throwing member 23 is driven to move in a circular shape. When the water-throwing member 23 passes through the tooth plate 226, the tooth ring 227 on the water-throwing member 23 meshes with the tooth plate 226 to make the water-throwing member 23 rotate, thereby throwing out the water in the firewood.

[0036] Continue to refer Figures 1 to 6 As shown, the water-repelling member 23 includes a spin barrel 231, a sealing portion 232 and an elastic portion 233. The spin barrel 231 is rotatably connected to the blocking ring 223 and the connecting ring 224. The sealing portion 232 is inserted at the bottom of the spin barrel 231 to block the bottom of the spin barrel 231. The elastic portion 233 is connected between the spin barrel 231 and the sealing portion 232 to connect the sealing portion 232 to the spin barrel 231. The elastic portion 233 is a telescopic rod with a built-in spring. The two ends of the telescopic rod are respectively connected to the sealing portion 232 and the spin barrel 231. When the sealing portion 232 is inserted into the bottom of the spin barrel 231, the spring in the elastic portion 233 is in a compressed state, so that the bottom of the sealing portion 232 is in contact with the guide In other embodiments, a ball bearing may be installed at the bottom of the sealing portion 232 to make the ball bearing in close contact with the top of the fixing ring 225. When the spin drum 231 rotates, the sealing portion 232 can be driven to rotate through the elastic portion 233. When the water-spinning member 23 moves to the groove 241 of the guide ring 24, the toothed ring 227 on the water-spinning member 23 is separated from the toothed plate 226. At this time, the sealing portion 232 is pushed downward by the spring in the elastic portion 233 to separate the sealing portion 232 from the spin drum 231, so that the firewood after water is thrown out of the spin drum 231 falls into the discharge portion 26, and the discharge portion 26 transports the firewood after water is thrown out to the drying mechanism 1 for drying.

[0037] Continue to refer Figures 1 to 6As shown, the water removal mechanism 2 also includes a driving member 29, which includes a gear ring 291, a tooth plate 292 and a tooth plate 3 293. The gear ring 291 is set in three numbers, and the three gear rings 291 are respectively connected to the three swinging barrels 231. The gear ring 291 is located below the connecting ring 224, the tooth plate 292 is connected to the inner side of the fixing ring 225, and the tooth plate 3 293 is connected to the shielding part 1 27. The tooth plate 292 and the tooth plate 3 293 are staggered. The gear ring 291 can mesh with the tooth plate 292 and the tooth plate 3 293 in turn, thereby driving the swinging barrel 231 and the sealing part 232 to reverse and rotate synchronously in turn, so as to discharge the firewood after the water is thrown away.

[0038] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the pressing mechanism 3 includes a guide ring 231, a lifting member 32 and a pressing portion 33. The guide ring 231 is connected to the inner top wall of the shell 21. The lifting member 32 and the pressing portion 33 are both provided in number. The three lifting members 32 are all connected to the connecting ring 224. The three pressing portions 33 are respectively rotatably connected to the three lifting members 32. The three pressing portions 33 are respectively located directly above the three swinging barrels 231. A protrusion 311 is provided at the bottom of the guide ring 231. When the connecting ring 224 rotates, the lifting member 32 is driven to move in a circular manner. When the lifting member 32 passes through the protrusion 311 of the guide ring 231, the lifting member 32 drives the pressing portion 33 to move downward, so that the pressing portion 33 extends into the swinging barrel 231 and squeezes the firewood in the swinging barrel 231, thereby squeezing out the water in the firewood to enhance the dehydration effect on the firewood.

[0039] Continue to refer Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the lifting member 32 includes a slide rail 321, a lifting part 322, a connecting rod 323 and an elastic part 2 324.

The elastic part 2 324 is connected between the lifting part 322 and the slide rail 321. The connecting rod 323 is connected to the lifting part 322. The top end of the connecting rod 323 contacts the inner bottom wall of the guide ring 221. The bottom end of the connecting rod 323 is rotatably connected to the pressing part 33. Next, when the lifting member 32 passes through the protrusion 311 of the second guide ring 31, under the guidance of the protrusion 311, the connecting rod 323 drives the lifting part 322 and the pressing part 33 to move downward, and squeezes the second elastic part 324, so that the pressing part 33 squeezes the firewood in the swinging tube 231. When the lifting member 32 passes over the protrusion 311, the lifting part 322 is pushed upward by the second elastic part 324, so that the lifting part 322, the pressing part 33 and the connecting rod 323 are reset, and the pressing part 33 is driven to move upward and separate from the swinging tube 231.

[0040] Working principle:

[0041] The driving source 221 is started to drive the connecting arm 222, the sealing ring 223 and the connecting ring 224 to rotate, and the three water-spinning parts 23 are driven to rotate, and the feeding mechanism 4 is started to sequentially convey the crushed firewood to the three spin barrels 231 and supported by the sealing part 232 in the spin barrel 231. When the spin barrel 231 passes through the tooth plate 226, the tooth ring 227 on the spin barrel 231 meshes with the tooth plate 226 for transmission, thereby driving the spin barrel 231 and the sealing part 232 to rotate, and when the spin barrel 231 and the sealing part 232 rotate, the firewood inside them is spun off.

[0042] When the connecting ring 224 rotates, it drives the lifting member 32 to move in a circular shape. When the lifting member 32 passes through the protrusion 311 of the guide ring 31, under the guidance of the protrusion 311, the connecting rod 323 drives the lifting part 322 and the pressing part 33 to move downward, and squeezes the elastic part 324, so that the pressing part 33 squeezes the firewood in the swinging cylinder 231, thereby squeezing out the water in the firewood. At this time, the swinging cylinder 231 and the sealing part 232 keep rotating, thereby throwing out the water in the firewood, and the thrown out water is blocked by the shielding part 28 to prevent the thrown out water from splashing in the shell 21.

[0043] When the lifting member 32 passes over the protrusion 311 , the second elastic portion 324 pushes the lifting portion 322 to reset the lifting portion 322 , the pressing portion 33 and the connecting rod 323 , and drives the pressing portion 33 to move upward and separate from the spinning drum 231 .

[0044] When the water-spinning part 23 moves to the groove 241 of the guide ring 24, the tooth ring 1 227 on the water-spinning part 23 separates from the tooth plate 1 226. At this time, the sealing part 232 is pushed downward by the spring in the elastic part 1 233 to separate the sealing part 232 and the spin barrel 231. The spin barrel 231 continues to move in a circular shape, and the tooth ring 291 meshes with the tooth plate 292 and the tooth plate 3 293 in turn. At this time, the spin barrel 231 is driven by the tooth ring 291 to reverse and forward in turn, and under the obstruction of the shielding part 27, the firewood after the water is thrown out of the water-spinning part 23 is transported to the drying mechanism 1 through the discharge part 26, and the drying mechanism 1 dries the firewood.
