Description

Technical Field

[0001] The invention relates to the technical field of pulverization, in particular to a raw material nano-pulverization device for preparing biochar. Background Art

[0002] Bio-organic fertilizer refers to a type of fertilizer that combines specific functional microorganisms with organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. It has the effects of both microbial fertilizer and organic fertilizer.

[0003] An animal feed crushing and granulating device and a working method thereof described in the patent application with the announcement number CN115888554A, which crushes the feed raw materials in multiple stages by means of a crushing mechanism, ensures the crushed particle size requirements, and simultaneously realizes the mixing of multiple raw materials and improves the mixing uniformity; at the same time, the set transition component improves and guides the mixed feed raw materials, and then the improved feed raw materials are extruded and granulated by the granulating mechanism. Through the cooperation of the above mechanisms, the raw material crushing, raw material quality improvement and granulation molding are integrated into an assembly line, which improves the production efficiency and solves the problem that the traditional crushing and granulating device cannot fully mix the raw materials after crushing, thereby affecting the granulation quality;

[0004] When preparing biochar, all kinds of abandoned crops need to be crushed, and then further fine crushing is required to turn them into powder, so that subsequent compaction can be used to complete the compression molding of the crushed powder. However, when the powder is rolled and compacted into particles using rotating rollers and grooves on the rollers, if there is more moisture in the powder, the viscosity will be greater and it will be difficult to separate from the feed. If there is less moisture in the powder, it will be difficult to be compacted, resulting in problems such as insufficient compaction. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a raw material nano-crushing device for preparing biochar, which achieves the purpose of solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A raw material nano-crushing device for preparing biochar, comprising a crusher, a compression granulator is fixedly connected to the bottom of the crusher, a working frame is fixedly connected to the bottom of the compression granulator, and a compression mechanism is arranged inside the compression granulator;

[0007] The compression mechanism comprises:

[0008] A rotating roller, which is arranged inside the compression granulator, is a circular columnar structure, and there are two rotating rollers. The compression granulator can control the two rotating rollers to rotate relative to each other;

[0009] The groove is opened in the inner wall of the rotating roller, and the inner wall of the groove is provided with a push plate, which is a square plate structure and is used to push the compressed powder.

[0010] Preferably, a fixing frame is fixedly connected to the inner wall of the groove, and two sides of the inner wall of the fixing frame are inclined surfaces.

[0011] Preferably, the inner wall of the push plate is slidably connected to two sliding plates, and one side of the two sliding plates is slidably connected to the inner wall of the fixed frame.

[0012] Preferably, the push plates are magnetic, and when the two push plates are close to each other, the magnetism is that opposite poles attract each other.

[0013] Preferably, a magnetic block is fixedly connected to the outer wall of the rotating roller, and the magnetic block has magnetism. When the magnetic block and the push plate are close to each other, the magnetism is that opposite poles attract each other.

[0014] Preferably, an auxiliary mechanism is provided on the inner wall of the fixed frame, and the auxiliary mechanism includes a fixed column, one end of the fixed column is fixedly connected to the inner wall of the groove, the outer wall of the fixed column is fixedly connected to a pull rope, one end of the pull rope is fixedly connected to a fixed block, the outer wall of the fixed block is fixedly connected to the outer wall of the sliding plate, and the pull rope is used to limit the position of the sliding plate.

[0015] Preferably, a first connecting groove is formed on one side of the rotating roller, and a second connecting groove is formed on the inner wall of the groove.

[0016] Preferably, the interior of the first communicating groove is respectively communicated with the exterior of the rotating roller and the interior of the second communicating groove, and the interior of the second communicating groove is communicated with the interior of the groove.

[0017] The present invention provides a raw material nano-crushing device for preparing biochar, which has the following beneficial effects:

[0018] 1. The present invention sets a compression mechanism. After the two grooves are filled with powder, when the two grooves approach each other as the rotating roller rotates, the push plates inside the grooves will quickly approach each other through the magnetic attraction between them, so that the push plates in the two grooves will be squeezed toward the middle at the same time, and the powder filled in the grooves will be fully squeezed and compacted, thereby improving the compactness of the compression and avoiding the problem of loose compaction under conventional rotary compaction using a roller.

[0019] 2. The present invention avoids the problem that the conventional rotary roller compaction operation can only compress the particles into small particles but is difficult to compress into large particles by providing a compression mechanism and also by moving the two grooves close to each other for compression.

[0020] 3. The present invention sets a compression mechanism. When the groove is moved to the bottom of the rotating roller, the push plate in the groove will also give a thrust to the compression block in the groove, so that the compression block in the groove can be more easily removed from the groove, avoiding the situation that the particles compressed by the current roller adhere to the depressions on the surface of the roller. At the same time, the stability of the material feeding is improved, and the working efficiency of compressing the waste crop powder into blocks is ensured.

[0021] 4. The present invention sets an auxiliary mechanism, so that the sliding plate can slide from the push plate to detach the part of the compression block that adheres to the sliding plate when it is compressed, thereby reducing the adhesion between the compression block and the push plate and the sliding plate as a whole, and then improving its falling stability, avoiding the problem of being difficult to fall due to adhesion to the push plate and the sliding plate.

[0022] 5. The present invention sets an auxiliary mechanism. Since both sides of the fixed frame are inclined surfaces, when the push plate pushes the compression block to move outward, the two sides of the compression block will naturally detach from the fixed frames on the left and right sides, so that the compression block will not detach along the surface of the fixed frame due to friction, but will detach directly, which can improve the effect of the compression block being pushed down and reduce the problem of the compression block adhering to the inner wall of the fixed frame due to friction.

[0023] 6. The present invention sets an auxiliary mechanism and forms a negative pressure by pulling back the push plate, so that a large amount of powder can be quickly drawn into the space between the inner wall of the fixed frame and the push plate, thereby completing the rapid filling of the powder and avoiding the problem of limiting the overall crushing and compression efficiency due to the deliberate reduction of the rotating roller's rotational compaction and agglomeration work in order to ensure sufficient filling of the fixed frame.

[0024] 7. The present invention sets an auxiliary mechanism, and the compression and separation method allows air to be automatically replenished into the fixed frame at this time, avoiding the problem of negative pressure formed inside the fixed frame and difficulty in detaching the particles when the push plate and the compression block are separated, thereby improving the stability of granulation and separation of the compression block.

DETAILED DESCRIPTION

[0038] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a raw material nano-crushing device for preparing biochar, comprising a crusher 1, a compression granulator 2 is fixedly connected to the bottom of the crusher 1, a working frame 5 is fixedly connected to the bottom of the compression granulator 2, and a compression mechanism 3 is arranged inside the compression granulator 2;

[0039] The compression mechanism 3 comprises:

[0040] The rotating roller 301 is arranged inside the compression granulator 2. The rotating roller 301 is a circular columnar structure. There are two rotating rollers 301. The compression granulator 2 can control the two rotating rollers 301 to rotate relative to each other.

[0041] A groove 302 is formed in the inner wall of the rotating roller 301. A push plate 304 is disposed on the inner wall of the groove 302. The push plate 304 is a square plate-shaped structure and is used to push the compressed powder.

[0042] When in use, the waste crops to be crushed are crushed in advance, and after the initial crushing, they are put into the crusher 1 for fine crushing, so that the waste crops are crushed into very fine powder particles;

[0043] The granules in the form of powder and crumbs after being crushed fall through the crushing roller in the crusher 1 and enter the compression granulator 2. At the same time, the compression granulator 2 which is started in advance controls the two rotating rollers 301 inside to rotate relative to each other, so that the two rotating rollers 301 use the grooves 302 provided inside to complete the function of filling the powder and pressing the rollers 301 closer to each other to form granules.

[0044] Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution: a fixing frame 303 is fixedly connected to the inner wall of the groove 302, and both sides of the inner wall of the fixing frame 303 are inclined surfaces.

[0045] Two sliding plates 305 are slidably connected to the inner wall of the push plate 304 , and one side of the two sliding plates 305 is slidably connected to the inner wall of the fixed frame 303 .

[0046] The push plates 304 are magnetic, and when two push plates 304 are close to each other, the magnetism is that opposite poles attract each other.

[0047] The outer wall of the rotating roller 301 is fixedly connected with a magnetic block 306, which has magnetism. When the magnetic block 306 and the push plate 304 are close to each other, the magnetism is that opposite poles attract each other.

[0048] When the powder falls onto the two rotating rollers 301, it will naturally fall into the groove 302, completing the filling of the groove 302. At the same time, the crops before crushing need to be pre-crushed and wetted in advance, so that the wet powder will accumulate in the groove 302 and be slightly higher than the groove 302. When the two grooves 302 are close to each other, the powder that is higher than the groove 302 is squeezed into the two grooves 302, forming a compaction effect on the inside, thereby compressing it into particles, which is convenient for subsequent biochar production;

[0049] After the two grooves 302 are filled with powder, as the two grooves 302 approach each other as the rotating roller 301 rotates, the push plates 304 in the grooves 302 quickly approach each other through the magnetic attraction between them, so that the push plates 304 in the two grooves 302 are pressed toward the middle at the same time, and the powder filled in the grooves 302 is fully pressed and compacted, thereby improving the compactness of the compression and avoiding the problem of loose compaction under conventional rotating compaction with a roller.

[0050] At the same time, the two grooves 302 are moved close to each other to compress, thereby avoiding the problem that the conventional rotary roller compaction can only compress the particles into small particles but is difficult to compress them into large particles.

[0051] As the rotating roller 301 continues to rotate, the two grooves 302 begin to rotate downward and move away from each other. At this time, the entire rectangular compressed block formed in the two grooves 302 will be broken and exist in their respective grooves 302. As the grooves 302 move downward, they automatically fall off to complete the unloading of compressed particles.

[0052] When the groove 302 is moved to the bottom of the rotating roller 301, the push plate 304 in the groove 302 will also start to give a thrust to the compressed block in the groove 302 due to its own heavier gravity, so that the compressed block in the groove 302 can be more easily removed from the groove 302, thereby avoiding the situation that the particles compressed by the roller are currently adhered to the depressions on the surface of the roller, and at the same time improving the stability of the material feeding, ensuring the working efficiency of compressing the waste crop powder into blocks;

[0053] When the compression block in the groove 302 is pushed down by the push plate 304, the push plate 304 will naturally continue to fall to the magnetic block 306 due to its own gravity, and be magnetically attracted to the magnetic block 306 by the magnetic attraction between them. However, the push plate 304 can overcome the magnetic attraction between it and the magnetic block 306 in a vertical state and continue to fall. Therefore, the push plate 304 will be pulled by the pull rope 402 at this time to limit the push plate 304 and prevent it from falling out.

[0054] When the push plate 304 is located in the groove 302 and slides, the push plate 304 and the sliding plates 305 on both sides thereof slide in the inner wall of the fixed frame 303, and the fixed frame 303 is located in the inner wall of the groove 302, so that the inner wall of the groove 302 forms a slope on the left and right sides. Then, when the push plate 304 pushes the compression block, the sliding plate 305 will slide along the inclined surface of the fixed frame 303, so that the sliding plate 305 will slide in the push plate 304 and gradually move away from the push plate 304, then the surface of the compression block pushed by the sliding plate 305 and the push plate 304 will move, so that the sliding plate 305 slides away from the push plate 304, so that the part of the compression block adhered to the sliding plate 305 when it is compressed is separated by movement, thereby reducing the adhesion between the compression block and the push plate 304 and the sliding plate 305 as a whole, and then improving its falling stability, avoiding the problem that it is still difficult to fall due to adhesion to the push plate 304 and the sliding plate 305;

[0055] Similarly, since both sides of the fixed frame 303 are inclined surfaces, when the push plate 304 pushes the compression block to move outward, the two sides of the compression block will naturally detach from the fixed frames 303 on the left and right sides, so that the compression block will not detach along the surface of the fixed frame 303 by friction, but will detach directly, which can improve the effect of the compression block being pushed down and reduce the problem of the compression block adhering to the inner wall of the fixed frame 303 due to friction.

[0056] After the push plate 304 pushes the compression block to the position of the magnetic block 306, as the rotating roller 301 continues to rotate, it will gradually rotate to the top position of the rotating roller 301 again. During this period, the push plate 304 is not in a vertical state, so the magnetic attraction between the push plate 304 and the magnetic block 306 will magnetically attract the push plate 304 and the sliding plate 305 to the position of the magnetic block 306, and the push plate 304 will not fall back to the deep part of the fixed frame 303 and cannot be reset;

[0057] When the push plate 304 rotates with the rotating roller 301 to a vertical position on the top of the rotating roller 301, the gravity of the push plate 304 and the sliding plate 305 can break free from the magnetic attraction between the magnetic block 306, so that they fall back to the fixed column 401 in the fixed frame 303. The rapid fall back at this time creates a negative pressure on the large amount of powder above by pulling back the push plate 304, and the large amount of powder is quickly drawn into the space between the inner wall of the fixed frame 303 and the push plate 304, completing the rapid filling of the powder, avoiding the problem of deliberately reducing the rotation compaction and block-making work of the rotating roller 301 in order to ensure that the fixed frame 303 is fully filled, resulting in the overall crushing and compression work efficiency being limited.

[0058] Example 3: Please refer to Figure 1-12 On the basis of the first and second embodiments, the present invention provides a technical solution: an auxiliary mechanism 4 is arranged on the inner wall of the fixed frame 303, the auxiliary mechanism 4 comprises a fixed column 401, one end of the fixed column 401 is fixedly connected to the inner wall of the groove 302, a pull rope 402 is fixedly connected to the outer wall of the fixed column 401, one end of the pull rope 402 is fixedly connected to a fixed block 403, the outer wall of the fixed block 403 is fixedly connected to the outer wall of the sliding plate 305, and the pull rope 402 is used to limit the position of the sliding plate 305.

[0059] A first connecting groove 404 is formed on one side of the rotating roller 301 , and a second connecting groove 405 is formed on the inner wall of the groove 302 .

[0060] The interior of the first communicating groove 404 is respectively connected to the exterior of the rotating roller 301 and the interior of the second communicating groove 405 , and the interior of the second communicating groove 405 is connected to the interior of the groove 302 ;

[0061] After the traditional roller compaction granulation, when the particles fall, negative pressure will be formed in the mold of the groove, which will make it difficult for the compacted particles to overcome the negative pressure and fall. The compression and separation method directly pushes out the compressed particles by moving the groove 302 in the fixed frame 303. At the same time, the space of the fixed frame 303 behind the groove 302 will be connected to the air outside the rotating roller 301 through the second connecting groove 405 and the first connecting groove 404, so that air will be automatically replenished at this time, avoiding the problem of negative pressure formed inside the fixed frame 303 and difficulty in detaching the particles when the push plate 304 is detached from the compression block, thereby improving the stability of the compression block granulation and detachment discharge.

[0062] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
