[0002] In the production and storage processes of industries such as chemicals, food, and pharmaceuticals, bagged powdery or granular materials, such as fertilizers, milk powder, and resins, often agglomerate into hard lumps of varying sizes due to moisture absorption, compression, or other reasons. These agglomerated materials can clog the feed inlet, severely affecting the continuity and stability of subsequent metering, packaging, or pneumatic conveying processes.

[0003] Currently, mechanized processing equipment for such agglomerated materials, such as the organic lumpy material crusher for agriculture disclosed in Chinese patent CN108273632A, typically has a complex structure integrating multiple devices for crushing, recycling, and heating. This results in high manufacturing and maintenance costs. These devices are primarily designed for specific sticky organic materials and are not entirely suitable for crushing ordinary powder agglomerated materials, making them uneconomical for small and medium-sized enterprises. Furthermore, while some agglomerated material breakers on the market are effective, their core structures often rely on high-speed rotating hammers or complex airflow systems, leading to high power consumption, easy wear, and extremely high requirements for bearing sealing performance. Dust easily penetrates the bearing housings of traditional crushers, causing rapid bearing wear and failure, thus affecting the stable operating life of the entire equipment and increasing the frequency and cost of downtime maintenance.

[0010] In addition to one or more features described herein, or as an alternative, further embodiments of the agglomerated material crushing mechanism may include: the drive assembly disposed outside the crushing cavity, comprising at least two transmission gears, a drive motor and a reduction mechanism, wherein the transmission gears correspond one-to-one with the rotating shafts and are fixedly fitted onto the ends of the corresponding rotating shafts, and the transmission gears corresponding to any two adjacent rotating shafts are meshed together; the output end of the drive motor is connected to the end of one of the rotating shafts through the reduction mechanism.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] Furthermore, in the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] by Figures 1 to 3Taking an example, this application provides a description and introduction to a material crushing mechanism for agglomerated materials. This application provides a material crushing mechanism for agglomerated materials, including a crushing cavity, at least two sets of crushing structures disposed within the crushing cavity, a support assembly for supporting each crushing structure within the crushing cavity, and a drive assembly connected to the support assembly for driving each crushing structure to move and crush the material. A crushing chamber 1 is used to enclose and form the aforementioned crushing cavity. The top inlet of the crushing chamber 1 is directly opposite the discharge outlet of the discharge bin, and the bottom outlet of the crushing chamber 1 is connected to the inlet of the pneumatic conveying pump. Both the top inlet and the bottom outlet of the crushing chamber 1 are connected to the crushing cavity. The crushing chamber 1 has a first side and a second side. The support assembly includes at least two rotating shafts, each arranged parallel to the other on the same plane and connected between the first side and the second side. The number of crushing structures corresponds to the number of rotating shafts, and the specific number of crushing structures and rotating shafts can be adaptively set according to the actual required crushing volume, the discharge outlet area of ​​the discharge bin, etc. The drive assembly is located on each rotating shaft and can drive any two adjacent rotating shafts to rotate in opposite directions so that the corresponding two sets of crushing structures interact to crush the material; each rotating shaft is provided with a bearing 9 at the connection with the crushing chamber 1, and each bearing 9 is provided with a seal between itself and the rotating shaft inside it; the drive assembly is at least partially built into a sealing protective cover 5 that is sealed to the crushing chamber 1.

[0027] By setting up the aforementioned counter-rotating crushing structure, agglomerated materials can be efficiently bitten and crushed. Simultaneously, after the agglomerated materials collide, they form a vortex motion between the gears and the housing, resulting in multiple impacts, friction, and crushing, leading to a significant crushing effect. By installing bearing components 9 and seals at the connection between the rotating shaft and the crushing chamber 1, dust can be effectively prevented from entering the bearing, extending its service life. This also ensures the internal and external isolation of the crushing chamber 1, preventing material spillage and environmental pollution. By embedding at least part of the drive assembly within the sealed protective cover 5, transmission components such as gears can be protected, preventing foreign objects from entering and damaging the mechanism. This further optimizes the crushing process for bagged block materials while ensuring pneumatic conveying in the next stage, restoring the material to a loose state at a lower cost, ensuring crushing stability. This further reduces manual operation and accelerates the production line's output efficiency.

[0028] In some embodiments, please refer to Figure 1 and Figure 3Each set of crushing structures includes a cylindrical body coaxially arranged along the extension direction of the rotation axis, and multiple crushing toothed rings sequentially arranged around the outer circumference of the cylindrical body. The cylindrical body and the multiple crushing toothed rings rotate synchronously with the corresponding rotation axis. The cylindrical body and the crushing toothed rings can be integrally formed or independently manufactured and used as assemblies. The cylindrical body and the corresponding rotation axis can also be integrally formed or used as assemblies; no specific limitation is made here. The crushing toothed rings of any two adjacent sets of crushing structures are arranged alternately along the extension direction of the rotation axis. This arrangement allows the toothed rings of adjacent crushing structures to form staggered shearing and squeezing actions during rotation, significantly enhancing the crushing effect on materials, and is particularly suitable for processing hard or tough agglomerated materials.

[0029] In some embodiments, please refer to Figure 3 Each rotating shaft has a consistent shape and size; the crushing tooth rings of each crushing structure have a consistent shape and size; and the cylindrical bodies of each crushing structure have consistent dimensions. This standardized design helps reduce the manufacturing and maintenance costs of the equipment, improves the interchangeability of parts, and ensures the uniform distribution of crushing force and operational stability.

[0030] In some embodiments, please refer to Figure 3 The minimum normal distance between the tooth of any fragmentation tooth ring in any set of fragmentation structures and the outer surface of the cylindrical body of the adjacent set of fragmentation structures is the same. This minimum normal distance is as follows: Figure 3 As shown in a. This uniform gap design ensures balanced crushing of materials of different particle sizes, avoiding localized excessive wear or uneven crushing, thus improving crushing quality and equipment durability.

[0031] In some embodiments, please refer to Figure 3 The maximum normal distance between the teeth of any crushing tooth ring in any set of crushing structures and the outer surface of the cylindrical body of the adjacent set of crushing structures on the plane of each rotation axis arrangement is the same. This maximum normal distance is as follows: Figure 3 As shown in b, and all of these distances are less than the minimum normal distance between the teeth of the crushing toothed ring and the outer surface of the cylindrical body it is connected to. This specific geometric relationship ensures that the crushing toothed ring can effectively grip and bite the material, while simultaneously forming an effective compression and grinding zone with the adjacent cylinder during rotation, achieving multi-stage crushing of the material and improving crushing efficiency and fine particle yield.

[0032] In some embodiments, the drive assembly is located outside the crushing cavity and includes at least two transmission gears 6, a drive motor, and a reduction mechanism, wherein the transmission gears 6 are as follows: Figure 3 As shown, the drive motor and reduction mechanism are not shown in the diagram. Figure 3As shown, each transmission gear 6 corresponds to a rotating shaft and is fixedly fitted onto the end of the corresponding rotating shaft. The transmission gears 6 corresponding to any two adjacent rotating shafts mesh with each other. The output end of the drive motor is connected to the end of one of the rotating shafts via a reduction mechanism. By externalizing the drive assembly and using gear transmission, the structure inside the crushing cavity is simplified, facilitating maintenance. Gear meshing ensures precise synchronization of the dual-shaft counter-rotation, guaranteeing reliable power transmission. As an optional but not limiting method, synchronous counter-rotation of adjacent shafts can also be achieved through sprocket and chain transmission or synchronous belt transmission, etc., without specific limitations here.

[0033] In some embodiments, such as Figure 3 As shown, at least two transmission gears 6 are located within the sealed protective cover 5. This design isolates the transmission components from the external environment, effectively preventing dust adhesion from affecting transmission accuracy or foreign objects from getting caught and causing jamming. It also provides safety protection for operators.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the crushing chamber 1 has a rectangular frame structure, including an upper chamber and a lower chamber fixedly connected to the upper chamber; the bearing component 9 is installed in the bearing mounting seat between the upper and lower chambers. The split chamber structure facilitates processing, assembly, and the inspection and replacement of internal components. At the same time, the integral design of the bearing mounting seat ensures support rigidity and coaxiality, which is beneficial to the stable operation of the shaft.

[0035] As an optional but not limiting implementation, bearing component 9 is a self-aligning ball bearing. Because self-aligning ball bearings have a certain self-aligning function, they can compensate for misalignment caused by installation errors or slight shaft deformation, ensuring smooth operation. Of course, depending on the load and operating conditions, bearing component 9 can also be selected from roller bearings, tapered roller bearings, or other types of rolling bearings; no specific limitations are made here.

[0036] Please see Figure 3 As a further optimization, the seal includes two lip seals, which are respectively positioned on both sides of the rolling element of the corresponding bearing component 9. The use of double-lip seals creates a bidirectional sealing effect, more effectively preventing dust from entering the bearing from the crushing chamber and preventing bearing grease leakage, significantly extending the bearing's service life under harsh operating conditions. Of course, other forms of seals, such as labyrinth seals, mechanical seals, or combined seals, can also be used to adapt to different sealing requirements and working environments.

[0037] In one specific embodiment, the agglomerated material crushing mechanism provided in this application includes a crushing chamber 1, two sets of crushing structures (a first crushing structure and a second crushing structure, each comprising a cylindrical body and multiple crushing toothed rings), two rotating shafts (a first rotating shaft and a second rotating shaft), a transmission gear 6, a crushing pressure plate 4, a sealing protective cover 5, a self-aligning ball bearing, an outer lip seal 7, an inner lip seal 8, and other components. Figures 1 to 3 As shown.

[0038] Specifically, the crushing chamber 1 is the main frame and supporting component of the entire mechanism. It can be divided into an upper and lower two-part structure. The upper and lower chambers can be locked together using hexagonal nuts 13, flat washers 14, spring washers 15, and hexagonal head bolts 16 to form a sealed chamber. For details, please refer to [reference needed]. Figure 2 The top of the crushing chamber 1 is provided with a feed inlet, which is positioned directly opposite the discharge inlet of the feeding chamber; the bottom is provided with a discharge outlet, which is connected to the feed inlet of the pneumatic conveying chamber pump.

[0039] The rotating shafts corresponding to the first and second crushing structures are arranged parallel to each other inside the crushing chamber 1. They are connected by a transmission gear 6, forming a rotating structure that rotates in opposite directions. The crushing toothed ring 2 of the first crushing structure and the crushing toothed ring 3 of the second crushing structure are both toothed crushing structures. When the block material enters the crushing chamber 1, it is engaged by the toothed structures rotating in opposite directions, thus achieving the purpose of crushing the block material.

[0040] Self-aligning ball bearings, outer lip seals 7, and inner lip seals 8 are installed at the bearing mounting positions and sealing positions on both sides of the first and second rotating shafts. All these components can be installed into the bearing mounting holes of the crushing chamber 1. After connection, the outer lip seals 7 and inner lip seals 8 installed on the self-aligning ball bearings isolate the crushing chamber 1 from the outside environment, ensuring that dust from inside and outside the chamber does not enter the self-aligning ball bearings and cause damage.

[0041] The transmission gear 6 can be connected to the first or second rotating shaft via the connecting key 11, the crushing pressure plate 4, and the internal hexagon socket head cap screw 12. The two transmission gears 6 form a forward and reverse rotating structure of the first and second rotating shafts through gear transmission.

[0042] The sealing protective cover 5 can be connected to the crushing chamber 1 via the internal hexagonal head screw 17 to protect the transmission gear 6 and prevent foreign objects from entering the gear transmission mechanism and seizing up, causing damage to the mechanism.

[0043] like Figure 3As shown, the other end of the first rotating shaft can be connected to the drive assembly via a fixed key 10 to input power to the crushing mechanism. Under the drive of the external drive source, the first rotating shaft begins to rotate, and at the same time, the gear transmission structure of the transmission gear 6 drives the second rotating shaft to rotate in the opposite direction, forming a forward and reverse rotation structure. When the lumpy material enters the crushing chamber 1 through the upper feed bin, it is bitten by the toothed structure of the crushing toothed ring 2 of the first crushing structure and the crushing toothed ring 3 of the second crushing structure, crushing the lumpy material into small particles. At the same time, after the lumpy material impacts each other, it will form a vortex motion between the crushing toothed ring and the crushing chamber 1, resulting in multiple impacts, friction, and crushing, and finally fall into the lower pneumatic conveying chamber pump, where it is pneumatically conveyed to the designated buffer chamber.

[0044] The self-aligning ball bearing provides rotational support for the first and second rotating shafts. The outer lip seal 7 and the inner lip seal 8 provide sealing structures on both sides of the self-aligning ball bearing, ensuring that powder does not enter the self-aligning ball bearing and cause damage to it. At the same time, it isolates the inside and outside of the crushing chamber 1, effectively preventing the material inside the crushing chamber 1 from overflowing and causing environmental impact.

[0045] This application also provides a system for crushing agglomerated materials, including the aforementioned agglomerated material crushing mechanism, a pneumatic conveying chamber pump, and a buffer chamber. The top inlet of the crushing chamber 1 of the agglomerated material crushing mechanism is directly opposite the discharge outlet of the discharge chamber. The bottom outlet of the crushing chamber 1 is connected to the inlet of the pneumatic conveying chamber pump. The pneumatic conveying chamber pump is provided with an inlet valve at its inlet. The pneumatic conveying chamber pump is also provided with an air inlet, an air inlet valve located at the air inlet, a discharge outlet, and a discharge valve located at the discharge outlet. The buffer chamber is connected to the discharge outlet.

[0046] The aforementioned agglomerated material crushing mechanism, pneumatic conveying pump, and buffer silo can be connected via pipelines and machinery to form a complete agglomerated material crushing system encompassing crushing, collection, conveying, and storage of the crushed material. Their connection relationships and material flow can be specifically configured as follows: The lumpy material first falls from the feed hopper to the crushing mechanism by gravity. The discharge port of the feed hopper can be directly and rigidly fixed to the feed port at the top of the crushing mechanism by bolting through a flange, so as to ensure that the lumpy material can fall into the crushing chamber without leakage and accurately.

[0047] Subsequently, the material is crushed into small particles in the crushing mechanism. The discharge port at the bottom of the crushing mechanism is connected to the inlet at the top of the pneumatic conveying silo pump through a section of material pipe or a connecting short pipe. The crushed small particles fall directly into the silo pump below through this pipe under the action of gravity.

[0048] As a pressure vessel, the pneumatic conveying silo pump can be equipped with a feed valve, a discharge valve, and an air inlet valve. When the material inside the silo pump reaches a certain amount, its feed valve closes, and compressed air then rushes in through the air inlet valve at the bottom of the silo pump, creating positive pressure inside the silo pump. The material and air mix to form a high-concentration gas-solid two-phase flow. Driven by pressure, this material flow is blown at a high speed through an independent conveying pipeline to a designated buffer silo at a distance.

[0049] Finally, the material undergoes gas-solid separation within the buffer silo. After separation by a dust collector or filter on the top of the silo, the material remains inside the silo, while the air is discharged from the system.

[0050] In conclusion, the agglomerated material crushing mechanism and crushing system proposed in this application have at least the following technical advantages: 1. By setting up a counter-rotating crushing structure, it can efficiently bite and crush agglomerated materials. At the same time, after the agglomerated materials hit each other, they will form a vortex motion between the gears and the casing, resulting in multiple mutual impacts, friction and crushing, with a significant crushing effect.

[0051] 2. By installing bearing components 9 and seals at the connection between the rotating shaft and the crushing chamber 1, dust can be effectively prevented from entering the bearing, extending the bearing's service life. At the same time, it ensures that the inside and outside of the crushing chamber 1 are isolated, preventing material spillage and environmental pollution.

[0052] 3. By embedding at least part of the drive components within the sealed protective cover 5, transmission components such as gears can be protected, preventing foreign objects from entering and causing damage to the mechanism.

[0053] 4. The crushing process for bagged block materials has been further optimized, while ensuring the pneumatic conveying in the next stage. This allows the material to be restored to a loose state at a lower cost, ensuring the stability of the crushing process. As a result, manual operation has been further reduced, and the production efficiency of the production line has been accelerated.

[0054] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
