Description

Technical Field

[0001] The present application relates to the technical field of compression molding equipment, and more specifically, to a biomass compression system. Background Art

[0002] In order to recycle biomass, it is often collected in a unified manner and then transported to a recycling plant. Since most biomass materials (such as solid agricultural waste and bulk domestic waste) are relatively fluffy, they take up a lot of space during transportation and are easily dropped from the transport vehicle to the ground during transportation, affecting the city appearance. Therefore, people often compress the solid waste through a solid waste compression device and then transport the compressed solid waste to a recycling plant.

[0003] Existing compression devices, such as the solid waste compression device proposed in Chinese Patent No. CN220611690U, are provided with a crushing rod, which allows the solid waste compression device to directly crush the solid waste before compression. A blanking plate and a cam are provided, and one side of the blanking plate is raised by the cam to keep the blanking plate in an inclined state, causing the solid waste compressed on the blanking plate to slide out of the compression box.

[0004] Before transporting solid waste to a recycling plant, irregular solid organic bulk materials such as agricultural waste, domestic waste, biomass, etc. need to be pre-processed (such as shredding) and then enter compression molding equipment multiple times to compress the solid waste to an energy density that is convenient for storage and transportation of solid bulk materials. The existing compression processing of agricultural waste and domestic waste is difficult, slow, and has low output, and cannot meet production needs. In view of this, we propose a biomass compression system. Utility Model Content

[0034] refer to Figure 1-6 , a technical solution proposed.

[0035] like Figure 1 and Figure 6As shown, a crushing structure 2 for crushing solid bulk materials and a multi-stage pressure structure for compressing solid bulk materials to form them are arranged in the storage bin 1. A feed port is arranged above the storage bin 1, and a compression chamber 7 is arranged below the feed port. When the storage bin 1 is opened, solid bulk materials can enter the compression chamber 7 from the feed port. At this time, the discharge gate 6 on the side of the storage bin 1 is in a closed state, and the crushing structure 2 is located above the compression chamber 7. The crushing structure 2, the storage bin 1 and the compression chamber 7 adopt clearance fit to achieve the closure of the joint surface, and the compression chamber 7 adopts a through structure to facilitate the compression molding of different materials.

[0036] like Figure 2 and Figure 3 As shown, the crushing structure 2 includes a crushing head 21 rotatably connected above the compression chamber 7, and the crushing head 21 is used to cut and compress the solid bulk material in the first stage. Here, two crushing heads 21 are provided, and the crushing head 21 is a fan-shaped structure as a whole. The outer side of the crushing head 21 is arc-shaped, and the solid bulk material cannot be retained on the outer side of the crushing head 21 for a long time, and the arc-shaped part is set in a sharp angle. With the rotation of the crushing head 21, the outer side of the crushing head 21 can crush the solid bulk material inside the compression chamber 7. A movable groove is provided above the compression chamber 7. The internal size of the movable groove meets the activity requirements of the crushing structure 2; a fixed block is rotatably connected to a position near the arc-shaped part on one side of the crushing pressure head 21, and a telescopic driving member 22 is rotatably connected to the other side of the fixed block. The telescopic driving member 22 consists of a driving source and a telescopic member. The driving source adopts electric drive, pneumatic drive, and electro-hydraulic drive according to different working conditions. The driving source can drive the telescopic member to perform telescopic movement. The telescopic member extends to apply a force to the crushing pressure head 21 to rotate it downward, and the telescopic member contracts to pull the crushing pressure head 21 to rotate it upward.

[0037] like Figure 4 , Figure 5 and Figure 3As shown, a fixed shaft 29 is fixedly connected to one side of the bottom end of the crushing head 21, and the rotation of the crushing head 21 can drive the fixed shaft 29 to rotate. The other end of the fixed shaft 29 is fixedly connected to the fixed frame, and the other side of the fixed frame is fixedly connected to an internal gear 28. The bottom end of the inner side of the internal gear 28 is meshedly connected with a connecting gear 27, and the outer side of the connecting gear 27 is meshedly connected with a connecting gear 1 26. The bottom end of the connecting gear 1 26 is meshedly connected with the internal gear 1 25. The internal gear 1 25 has the same structure as the internal gear 28 and is symmetrically arranged. The connecting gear 1 26 The structure is the same as the connecting gear 27. The connecting gear 1 26 and the connecting gear 2 27 are both rotatably connected to a fixed shaft for limiting their position on the opposite side. The connecting gear 1 26 and the connecting gear 2 27 are also symmetrically arranged. The width of the connecting gear 1 26 is greater than the width of the internal gear 1 25. The width of the connecting gear 2 27 is greater than the width of the internal gear 2 28. The part of the connecting gear 1 26 that is not meshed with the internal gear 1 25 is meshed with the part of the connecting gear 2 27 that is not meshed with the internal gear 2 28. The connecting gear 1 26 and the connecting gear 2 27 are staggered.

[0038] The extension and retraction of the telescopic driving member 22 can drive the crushing head 21 to rotate, the rotation of the crushing head 21 can drive the fixed shaft 29 to rotate, the rotation of the fixed shaft 29 can drive the internal gear 28 to rotate, the rotation of the internal gear 28 can drive the connecting gear 27 to rotate, the rotation of the connecting gear 27 can drive the connecting gear 1 26 to rotate in the opposite direction, and the connecting gear 1 26 rotates in the opposite direction to drive the internal gear 1 25 to rotate in the same direction.

[0039] like Figure 3 and Figure 4 As shown, the outer side of the inner gear 1 25 is fixedly connected with a positioning frame, and the middle part of the positioning frame near the inner gear 1 25 is fixedly connected with a fixed shaft 1 251, a through hole is provided in the middle of the fixed shaft 29, and the inner side of the through hole is rotatably connected with the fixed shaft 1 251, the fixed shaft 1 251 penetrates the fixed shaft 29, the fixed shaft 1 251 is fixedly connected with the side shovel plate 211, the inner gear 1 25 and the inner gear 2 28 are in the same straight line, the fixed shaft 29 is fixedly connected with the crushing pressure head 21, and the fixed shaft 29 is fixedly connected with the fixed shaft 1 251 Able to rotate coaxially, the diameter of connecting gear 27 is smaller than the radius of inner gear 28, the highest point of connecting gear 27 is lower than the lowest point of fixed shaft 29, the diameter of connecting gear 1 26 is smaller than the radius of inner gear 1 25, the highest point of connecting gear 1 26 is lower than the lowest point of fixed shaft 1 251, connecting gear 1 26 is located on one side of the bottom end of fixed shaft 1 251, connecting gear 27 is located on the other side of the bottom end of fixed shaft 1 251, and the rotation of connecting gear 1 26 and connecting gear 2 27 does not interfere with the rotation of fixed shaft 1 251;

[0040] The inner gear 1 25, the fixed shaft 1 251, the connecting gear 1 26, the connecting gear 27 and the inner gear 28 are all arranged on the inner side of the linkage member 24. The linkage member 24 is arranged on the side wall of the compression chamber 7. There is a gap between the inner gear 1 25 and the inner gear 28. The fixed shaft on one side of the connecting gear 1 26 and the connecting gear 2 27 passes through the gap between the inner gear 1 25 and the inner gear 28, and is fixedly connected to the inner side of the linkage member 24.

[0041] The rotation of the internal gear 25 drives the fixed shaft 251 to rotate, and the rotation of the fixed shaft 251 drives the side shovel plate 211 to rotate. The rotation direction of the side shovel plate 211 is opposite to the rotation direction of the crushing head 21. One side of the side shovel plate 211 is in contact with the crushing head 21, and the other side of the side shovel plate 211 is set to an inclined state. The crushing head 21 rotating in the opposite direction can clean and scrape the side of the crushing head 21 that has completed crushing the solid bulk material on one side.

[0042] like Figure 2 As shown, the other side of the bottom end of the side shovel plate 211 is rotatably connected with a connecting shaft 23, and the connecting shaft 23 connects the two side shovel plates 211. The two side shovel plates 211 can rotate freely at both ends of the connecting shaft 23. When the driving states of the telescopic driving member 22 rotatably connected at one end of the two side shovel plates 211 are different, the two side shovel plates 211 do not interfere with each other, forming staggered crushing. The connection relationship between the connecting shaft 23 and the two side shovel plates 211 can also be changed to fixed. At this time, only one telescopic driving member 22 is needed to drive the crushing press head 21. The force of the rotation of one crushing head 21 is converted into a force for the reverse rotation of a side shovel plate 211 through the internal structure of the linkage 24. One side shovel plate 211 drives the other side shovel plate 211 to rotate synchronously through the fixedly connected connecting shaft 23, so that the synchronous rotation of the two side shovel plates 211 can be achieved. The force of the rotation of the other side shovel plate 211 is transmitted to the internal structure of the linkage 24, and is converted into a force for the reverse rotation of the crushing head 21 and the side shovel plate 211 through the internal structure of the linkage 24, thereby achieving synchronous crushing of solid bulk materials.

[0043] like Figure 1 and Figure 6As shown, the top, side and rear of the inner side of the compression chamber 7 are all provided with a multi-stage pressure structure for continuously compressing irregular solid organic bulk materials. The top multi-stage pressure structure is arranged on one side of the top of the compression chamber 7 and is rotatably connected to a crushing structure 2, which can cut off and perform the first-stage compression of the solid bulk materials. The rear multi-stage pressure structure can perform the second-stage compression of the solid bulk materials. The rear multi-stage pressure structure includes a base 3 arranged on the outer side of the bottom end of the storage bin 1, and a rear pressure head 5 for compressing the rear of the solid bulk materials is arranged in the middle of the base 3. The side multi-stage pressure structure performs the third-stage compression and maintains the pressure on the side of the solid bulk materials to achieve the final compression molding of the solid bulk materials. The side of the compression chamber 7 is fixedly provided with a pressure head for compressing the solid bulk materials. A side pressure head 8 is used to compress the bulk material on the side. A discharge gate 6 is slidingly arranged on one side of the side pressure head 8. The side pressure head 8 can push the solid block material after compression and forming out of the discharge gate 6. A locking member 4 is arranged on one side of the rear pressure head 5. The locking member 4 is composed of a hydraulic member and a telescopic connecting rod. The output end of the hydraulic member is fixedly connected to the telescopic connecting rod. A card block is fixedly connected to the other end of the telescopic connecting rod. The hydraulic member drives the telescopic connecting rod to extend and retract. The telescopic connecting rod drives the card block to move. The card block moves and is engaged with the card groove arranged on the side of the crushing pressure head 21, thereby locking the crushing structure 2 above the compression chamber 7, so that the rear pressure head 5 and the side pressure head 8 can perform multi-stage compression on the solid bulk material shredded and compressed by the crushing structure 2 to form it.

[0044] When compressing and molding solid bulk materials, the crushing structure 2 is first opened, and the discharge gate 6 is closed. The solid bulk materials enter the compression chamber 7 through the storage bin 1, and the solid bulk materials are cut and compressed by the crushing structure 2. The telescopic driving member 22 in the crushing structure 2 extends to drive the crushing head 21 to rotate downward. The crushing head 21 rotates downward to cut the solid bulk materials. Then the telescopic driving member 22 contracts to drive the crushing head 21 to rotate upward. At the same time, the upward rotation force of the crushing head 21 drives the fixed shaft 29 to rotate synchronously. The fixed shaft 29 The rotation drives the inner gear 28 to rotate, the rotation of the inner gear 28 drives the connecting gear 27 to rotate, the connecting gear 27 rotates to cause the connecting gear 1 26 meshing with it to rotate in the opposite direction, the connecting gear 1 26 rotates in the opposite direction to drive the inner gear 1 25 to rotate synchronously, the synchronous rotation of the inner gear 1 25 drives the fixed shaft 1 251 to rotate, the rotation of the fixed shaft 1 251 drives the side shovel plate 211 to rotate synchronously therewith, at this time, the side shovel plate 211 and the crushing head 21 rotate in the opposite direction, and the side shovel plate 211 can scrape and clean the debris on the side of the crushing head 21.

[0045] Silo 1, crushing structure 2, base 3, locking member 4, rear pressure head 5, discharge gate 6, compression chamber 7, side pressure head 8. The above devices can be powered by electric drive, pneumatic drive or electro-hydraulic drive according to different working conditions.

[0046] The locking member 4 locks the crushing ram 2, and the rear ram 5 pushes the solid bulk material in the compression chamber 7 to compress the material in the compression chamber, perform the second stage of compression and maintain the pressure, and the side ram 8 pushes the solid bulk material in the compression chamber 7 to perform the third stage of compression and maintain the pressure, so as to achieve the final compression molding of the solid bulk material. The discharge gate 6 is opened, and the solid block material after compression molding is pushed out of the compression chamber 7 by the side ram 8, and the above steps are repeated to achieve the continuous operation of multi-stage compression molding of solid bulk material.
