Detailed Implementation

[0018] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0019] A drying and shaping device for biomass pyrolysis catalysis, such as Figures 1-5 As shown, the system includes a support frame 3, rotating drum A101, rotating drum B103, fixed drum 102, spiral conveyor blade 104, connecting rod 6, drive motor 601, connecting plate 602, dispersing plate 603, spring 604, and pressure block 605. The rotating drum A101 is rotatably connected to the left side of the support frame 3, the fixed drum 102 is fixedly connected to the middle part of the support frame 3, and the rotating drum B103 is rotatably connected to the right side of the support frame 3. When rotating drums A101 and B103 rotate, the fixed drum 102... 2 does not rotate with rotating drums A101 and B103. Both rotating drums A101 and B103 have spiral conveying blades 104 rotating in the same direction on their inner walls. The spiral conveying blades 104 rotate with rotating drums A101 and B103. Rotating drums A101 and B103 are used to transport biomass raw materials, and the spiral conveying blades 104 facilitate the movement of the biomass raw materials. A connecting rod 6 is connected to the top of the fixed drum 102, and a rectangular rod (see [reference]) is connected to the lower rear side of the connecting rod 6. Figure 3The other end of the rectangular rod is fixedly connected to the inner wall of the fixed bucket 102. A drive motor 601 is connected to the right side of the bottom end of the connecting rod 6, and the connecting rod 6 is fixedly connected to the drive motor 601. A rotating shaft 606 is rotatably connected to the left side of the bottom end of the connecting rod 6, and the connecting rod 6 is movably connected to the rotating shaft 606. The output shaft of the drive motor 601 is connected to the rotating shaft 606. The drive motor 601 drives the rotating shaft 606 to rotate, thereby driving the dispersing plate 603 to disperse the biomass raw materials. Connecting plates 602 are spaced circumferentially on the rotating shaft 606. Each connecting plate 602 has a rectangular hole 6021 on the side near the rotating shaft 606. This rectangular hole 6021 facilitates the dispersal of biomass raw materials. Raw materials pass through, preventing biomass raw materials from accumulating on the connecting plate 602. A dispersing plate 603 is slidably connected to the end of the connecting plate 602 away from the rotating shaft 606. A spring 604 is connected between the dispersing plate 603 and the connecting plate 602. A groove is provided on one side of the dispersing plate 603, and the end of the connecting plate 602 slides in the groove. One end of the spring 604 is connected to the inner wall of the groove, and the other end is connected to the end of the connecting plate 602. Dispersing holes 6031 are spaced apart on the dispersing plate 603. A pressure block 605 is provided at the top inner end of the fixed barrel 102. The front end face of the pressure block 605 is a vertical surface, and the rear end face of the pressure block 605 is a smooth curved surface. The dispersing plate 603 can contact the pressure block 605.

[0020] like Figure 1 and Figure 2 As shown, it also includes a power assembly 2, which includes a sliding rail 106, a support plate 301, a rotary motor 201, a connecting shaft 202, and a drive wheel 203. The outer walls of both rotating barrels A101 and B103 are fixedly fitted with sliding rails 106. Support plates 301 are symmetrically arranged on the left and right sides of the front of the support frame 3. The top of the right support plate 301 is equipped with a rotary motor 201. The tops of both the right and left support plates 301 are rotatably connected to drive wheels 203. The driving wheels 203 slide within the sliding tracks 106 on the left and right sides respectively. A connecting shaft 202 connects the two driving wheels 203. The output end of the rotary motor 201 is connected to the driving wheel 203 on the right side. The rotary motor 201 is used to drive the driving wheels 203 on both sides to rotate. The driving wheels 203 drive the rotating drums A101 and B103 to rotate. The rotation of the rotating drums A101 and B103 will cause the biomass raw materials in the rotating drums A101 and B103 to move in one direction.

[0021] like Figure 1 , Figure 2 and Figure 5As shown, it also includes a sealing cover 105, a feed hopper 5, and a discharge hopper 7. The left end of the rotating drum A101 and the right end of the rotating drum B103 are both connected to the sealing cover 105. The bottom end of the sealing cover 105 is fixedly connected to the support frame 3. The sealing cover 105 is movably connected to the rotating drum A101 and the rotating drum B103. The sealing cover 105 will not rotate with the rotating drum A101 and the rotating drum B103. The left end of the left sealing cover 105 is connected to the discharge hopper 7, which is used to output the dried biomass raw materials for easy collection. The right end of the right sealing cover 105 is connected to the feed hopper 5, which is used to input the biomass raw materials.

[0022] like Figure 1 and Figure 5 As shown, it also includes a dryer 4 and a mounting frame 401. The mounting frame 401 is connected to the right side of the support frame 3. The dryer 4 is located at the top of the mounting frame 401. The dryer 4 is used to provide hot air to dry the biomass raw materials. The air outlet of the dryer 4 is connected to the sealing cover 105 on the right side.

[0023] During operation, biomass raw materials are first fed into the rotating drum B103 through the feed hopper 5. The rotating motor 201 is then started, directly driving the right drive wheel 203 to rotate. This drive wheel, via the connecting shaft 202, drives the left drive wheel 203 to rotate. The two drive wheels 203 respectively drive rotating drums A101 and B103. The spiral conveying blades 104 on the inner walls of rotating drums A101 and B103 rotate accordingly, conveying the biomass raw materials from rotating drum B103 to rotating drum A101. During the conveying process, the dryer 4 on the mounting frame 401 sends hot air into the rotating drums A101 and B103 through the air outlet to dry the biomass raw materials. At the same time, the drive motor 601 starts, and the output shaft of the drive motor 601 drives the rotating shaft 606 to rotate. The rotating shaft 606 drives the connecting plate 602 to rotate, and the connecting plate 602 drives the dispersing plate 603 to rotate. The dispersing plate 603 disperses the biomass raw materials conveyed to the bottom of the fixed drum 102, and the agglomerated and clumped biomass raw materials will pass through the dispersing plate 603. The dispersing holes 6031 on plate 03 are then dispersed. If some biomass raw materials adhere to the dispersing plate 603, when the dispersing plate 603 rotates to the top of the fixed barrel 102 and contacts the pressure block 605, the pressure block 605 squeezes the dispersing plate 603, causing the dispersing plate 603 to slide downward along the connecting plate 602. At this time, the spring 604 changes from its initial state to a compressed state. When the dispersing plate 603 leaves the smooth curved surface of the pressure block 605, it will directly contact the top of the fixed barrel 102. At this time, under the elastic force of the spring 604, The dispersing plate 603 will return to its original position along the connecting plate 602, and the dispersing plate 603 will directly impact the inner top of the fixed barrel 102. During this impact process, the biomass raw materials adhering to the dispersing plate 603 will fall off the dispersing plate 603. The drive motor 601 drives the dispersing plate 603 to continuously disperse the biomass raw materials to avoid the accumulation of biomass raw materials, which would lead to incomplete drying. Finally, the dried and shaped biomass raw materials are discharged through the discharge hopper 7 on the sealing cover 105 at the left end of the rotating barrel A101.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
