Description

Technical Field

[0001] This invention relates to the field of building aggregate processing technology, specifically to an aggregate processing device and method for water-force coupling weakening and directional collision crushing. Background Technology

[0002] In engineering applications, aggregate crushing is a crucial link in the building materials production chain, and its energy efficiency and product quality directly determine the cost and performance of subsequent concrete mix design. The engineering community has placed higher demands on the particle shape, gradation, and internal microstructure integrity of aggregates. Firstly, for the preparation of high-strength concrete, the aggregates are required to have excellent particle morphology and interfacial bonding performance, and the content of needle-like and flaky particles must be strictly controlled at an extremely low level to avoid becoming weak points for crack initiation and propagation under stress. Secondly, for concrete structures in freeze-thaw and erosion-resistant environments, microcracks and defects inside the aggregate will directly deteriorate the long-term durability of the concrete. Therefore, the crushing process should protect the integrity of the internal structure of the aggregate as much as possible to avoid secondary damage. However, existing aggregate crushing processes have significant limitations in terms of technical principles. Traditional crushing equipment (such as jaw crushers, cone crushers, and impact crushers) relies on crushing components to apply high-stress compression or impact to the aggregate, causing it to fracture along internal defects through "external force overcoming internal force." Taking common crushing processes as an example, their effectiveness is usually characterized and evaluated only by macroscopic indicators such as "crushing ratio," "processing capacity," and "content of needle-like and flaky particles." This technical approach based on the concept of "forced crushing" essentially consumes a large amount of energy to overcome the ultimate strength of the aggregate itself, rather than guiding it to disintegrate along predetermined weak points. Rock materials naturally possess high fracture toughness and compressive strength. Traditional crushing methods often require applying loads far exceeding the stress required for fracture in order to break the aggregate. This results in two main consequences: firstly, a large amount of energy is dissipated as heat, noise, and equipment wear, leading to a persistently low energy utilization rate; secondly, excessive stress can create numerous uncontrollable microcracks and damage within the crushed aggregate. These secondary defects will become penetration channels and weak points in strength during subsequent concrete mixing and service, ultimately deteriorating the overall performance of the concrete.

[0003] In fact, the strength properties of rock, as a natural porous material, are not constant. The presence of water significantly alters the mechanical behavior of rock: water molecules enter the mineral lattice or the tip of microcracks through capillary adsorption and wedging, producing a "water wedge effect," which significantly reduces the critical stress required for crack propagation. This phenomenon is known as the "water-induced weakening effect" in rock mechanics. However, this natural law has not been systematically applied in existing aggregate crushing process designs. Aggregates are usually introduced into the crushing chamber in a dry state, with their strength at its peak. The crushing process must be carried out in a "hard-on-hard" manner, making it difficult to reconcile the contradiction between energy efficiency and product quality.

[0004] Although existing collision crushing equipment has been used on a small scale, its core control logic still has obvious defects: Firstly, most crushing processes are single-stage crushing, making it impossible to achieve phased control of weakening crushing and defect elimination. The water-induced weakening effect of aggregates in a saturated, surface-dry state can significantly reduce crushing energy consumption, but if only one crushing is performed, it is difficult to fully release existing defects or completely eliminate residual internal microcracks after weakening. Conversely, if dry aggregates are directly subjected to high-intensity crushing, energy consumption is high and damage is severe. Existing equipment lacks the capability to design differentiated crushing conditions for both stages.

[0005] Secondly, the crushing energy cannot be dynamically matched according to the aggregate moisture content. The equipment usually operates with fixed parameters, failing to take advantage of the weakening effect of moisture on aggregates to actively reduce crushing energy consumption. This results in energy redundancy when crushing high-moisture-content aggregates and insufficient crushing of low-moisture-content aggregates, making it impossible to achieve the optimal matching of "material state - crushing energy".

[0006] Third, there is a lack of proactive control over the evolution of internal defects in aggregates. Existing processes treat crushing as an instantaneous impact event, failing to utilize the transient high pressure generated by pore water in saturated surface-dry aggregates at the moment of impact to induce cracks to propagate directionally along primary defects. This results in disordered crack proliferation, making it difficult to fully release existing defects and easily generating new secondary damage.

[0007] With the continued growth in demand for high-quality manufactured aggregates and increasingly stringent requirements for low-carbon production, the limitations of traditional crushing processes have become increasingly apparent. To address this, we introduce an aggregate processing device and method that combines hydraulic-force coupling weakening and directional impact crushing. Summary of the Invention

[0020] This invention also provides a processing method for an aggregate processing device that uses water-force coupling weakening and directional collision crushing, specifically including the following steps: S1, the soaking module is used to wet the input aggregate. The fully wetted aggregate is introduced into the primary drying and sorting device through the aggregate conveyor belt. S2. The primary drying and sorting device continuously heats and sorts the aggregates to prepare saturated surface-dry aggregates of similar particle size for crushing. S3. Saturated surface dry crushed aggregate is introduced to the upper collision component through the primary screw conveyor, where it is accelerated and collided, and then enters the secondary drying unit for complete drying. S4. The completely dried aggregate is fed into the lower collision component by the secondary screw conveyor, where it is accelerated and collided. The aggregate after collision is then transferred to the tertiary sorting device, which finally outputs the finished crushed aggregate.

[0021] Compared with existing technologies, the beneficial effects of this invention are as follows: By pre-soaking the aggregate to a saturated state and controlling it to saturated surface dryness, the cohesive strength between mineral particles is significantly reduced by the wedging effect of water molecules, so that the aggregate is in a stress-weakened state before entering the crushing stage; by using aggregate acceleration for collision, the impact energy is completely absorbed by the aggregate itself, avoiding the energy transfer loss between the crushing components and the aggregate in traditional crushing. This strategy achieves the first collision in a saturated surface dry state, and under the dual effects of increased aggregate density and reduced strength, it effectively lowers the stress threshold required to trigger crushing, thereby improving the energy utilization efficiency of the crushing process from the source.

[0022] This invention employs a two-stage collision process based on aggregate moisture content grading. The first collision uses saturated, surface-dry aggregate at high speed, fully utilizing the transient high-pressure effect of pore water to expand the crack network and fully release existing defects. The second collision uses completely dry aggregate at low speed, allowing the aggregate to precisely disintegrate along the weak surface formed by the first collision. This avoids energy waste caused by over-crushing and eliminates hidden defects remaining inside the aggregate. This strategy transforms traditional single-stage forced crushing into a two-stage collision control based on moisture content grading, achieving directional induction and complete elimination of internal defects, significantly improving the internal damage state and particle shape quality of the aggregate.

[0023] This invention employs a coaxial transmission design to ensure that the two sets of acceleration components on the left and right sides of the same layer consistently project aggregate at the same frequency, fundamentally guaranteeing the consistency of the convergence sequence of the two aggregate flows. Simultaneously, the ejected high-speed airflow from opposite directions assists in guiding the aggregate trajectory, ensuring that the two aggregate flows precisely converge at the designated collision zone. This structural design, while ensuring long-term operational reliability, minimizes energy loss due to skewed collisions through precise control of the collision point, maximizing the use of impact energy for aggregate crushing rather than deflection and dissipation, thus providing a hardware foundation for the stable realization of water-mechanical coupling crushing effects.

[0024] By pre-soaking the aggregate to be crushed to saturation and adjusting it to saturated surface dryness, the cohesive strength of the aggregate particles is reduced by the wedging effect of water molecules. Then, two groups of aggregates of the same particle size are accelerated to a set speed through synchronous acceleration and precisely collided in the collision chamber. The collision rate is adjusted according to the moisture content of the aggregate (high moisture content corresponds to high collision speed, and low moisture content corresponds to low collision speed) to optimize the crushing effect and eliminate internal defects and cracks. This achieves the weakening of strength in the aggregate crushing process and efficient energy utilization, effectively overcoming the problems of severe internal damage, many needle-like and flaky particles, and energy waste caused by excessively high aggregate stress levels in traditional crushing methods. It significantly improves the energy efficiency of aggregate crushing and the quality of finished products. Attached Figure Description

The bottom of the upper collision chamber 30305 is connected to the feed port of the secondary drying device 302 via the sixth material guide connecting pipe 30208. The lower layer is connected to the left and right circular shells 30309 by a lower hollow guide channel 30307. The lower hollow guide channel 30307 is connected to the lower collision chamber 30308 in the middle. The bottom outlet of the lower collision chamber 30308 is connected to the inlet of the three-stage sorting device 305 by a seventh guide connecting pipe 30505. Both the upper collision chamber 30305 and the lower collision chamber 30308 have ventilation holes 30318 on their upper surfaces.

[0038] The auxiliary pneumatic device 304 includes an air pump 30401, a pressure stabilizing tank 30403 connected to the air pump 30401, and a flow guide nozzle 30402 connected to the bottom of the pressure stabilizing tank 30403 by an air guide pipe 30404. The flow guide nozzle 30402 is fixed to the outer ends of the upper hollow guide channel 30304 and the lower hollow guide channel 30307, ​​respectively.

[0039] The three-stage sorting device 305 includes a three-stage sorting housing 30501, a third screen cylinder disposed inside the three-stage sorting housing 30501, a third inner spiral blade fixed to the inner wall of the third screen cylinder, and a third rotating rod fixed to the middle of the third inner spiral blade. A fourth drive motor 30502 is fixed to one end of the three-stage sorting housing 30501, and one end of the third rotating rod extends out of the three-stage sorting housing 30501 and is connected to the output end of the fourth drive motor 30502. The bottom of the discharge port of the three-stage sorting shell 30501 is connected to the finished product conveyor belt 30504, and the bottom of the other end of the three-stage sorting shell 30501 is provided with a second screening discharge pipe 30503.

[0040] This invention also provides a processing method for an aggregate processing device that uses water-force coupling weakening and directional collision crushing, specifically including the following steps: S1, Immersion module 2 is used to wet the input aggregate, and the fully wetted aggregate is introduced into the primary drying and sorting device 301 through aggregate conveyor belt 203. S2. The primary drying and sorting device 301 continuously heats and sorts the aggregates to prepare saturated surface-dry aggregates of similar particle size for crushing. S3. Saturated surface dry aggregate is introduced to the upper collision component through the primary screw conveyor 30301 to accelerate and collide with the saturated surface dry aggregate, and then enters the secondary drying device 302 for complete drying. S4. The completely dried aggregate is fed into the lower collision component by the secondary screw conveyor 30302, where the completely dried aggregate is accelerated and collided. The aggregate after collision is transferred to the tertiary sorting device 305, and finally the finished crushed aggregate is output by the tertiary sorting device 305.

[0041] This invention pre-soaks the aggregate to saturation and adjusts it to saturated surface dryness. The wedging effect of water molecules significantly reduces the cohesive strength between mineral particles, placing the aggregate in a stress-weakened state before it enters the crushing stage. It then employs aggregate acceleration and collision, ensuring that the impact energy is completely absorbed by the aggregate itself, avoiding energy transfer losses between the crushing components and the aggregate in traditional crushing processes. This strategy achieves the first collision in a saturated surface dry state. Under the dual effects of increased aggregate density and reduced strength, it effectively lowers the stress threshold required to trigger crushing, thus improving the energy utilization efficiency of the crushing process from the source.

[0042] This invention employs a two-stage collision process based on aggregate moisture content grading. The first collision uses saturated, surface-dry aggregate at high speed, fully utilizing the transient high-pressure effect of pore water to expand the crack network and fully release existing defects. The second collision uses completely dry aggregate at low speed, allowing the aggregate to precisely disintegrate along the weak surface formed by the first collision. This avoids energy waste caused by over-crushing and eliminates hidden defects remaining inside the aggregate. This strategy transforms traditional single-stage forced crushing into a two-stage collision control based on moisture content grading, achieving directional induction and complete elimination of internal defects, significantly improving the internal damage state and particle shape quality of the aggregate.

[0043] This invention employs a coaxial transmission design to ensure that the two sets of acceleration components on the left and right sides of the same layer consistently project aggregate at the same frequency, fundamentally guaranteeing the consistency of the convergence sequence of the two aggregate flows. Simultaneously, the opposing high-speed airflow ejected through the guide nozzle 30402 assists in guiding the aggregate trajectory, ensuring that the two aggregate flows precisely converge at the designated collision zone. This structural design, while ensuring long-term operational reliability, minimizes energy loss due to skewed collisions through precise control of the collision point, maximizing the use of impact energy for aggregate crushing rather than deflection and dissipation, thus providing a hardware foundation for the stable realization of water-mechanical coupling crushing effects.

[0044] Specifically, when using it: The global control module 1 serves as the control core of the entire device. Its touch screen is used by operators to input processing parameters (such as soaking time, drying temperature, collision speed, etc.). After receiving the instructions, the PLC controller built into the touch screen synchronously controls the start, stop, speed and operating parameters of all driving components (such as the first drive motor 201, the second drive motor 30106, the third drive motor 30202, the acceleration motor 30310, the fourth drive motor 30502, etc.) in the soaking module 2 and the collision module 3. This ensures that all modules work together to achieve automated and standardized control of aggregate processing, avoid human error, and improve processing stability.

[0045] The core function of the soaking module 2 is to fully wet the aggregate and weaken the internal cracks of the aggregate by the penetration of water, thereby reducing the difficulty of subsequent directional impact crushing. It relies on the reasonable layout of the soaking conveying device and the linkage of the drive structure to realize continuous and unblocked soaking of the aggregate. The specific process is as follows: The workers put the aggregate to be processed and water into the first soaking cylinder 216 through the feeding hopper 206. The global control module 1 controls the first drive motor 201 to start. The output end of the first drive motor 201 drives the first drive shaft 210 to rotate. The first worm 211 on the first drive shaft 210 meshes with the first driven worm wheel 207 in the middle of the second drive shaft 212, thereby driving the second drive shaft 212 to rotate. The second worm gears 209 at both ends of the second drive shaft 212 mesh with the corresponding second driven worm gears 202, driving the conveying shafts 218 in each soaking cylinder to rotate synchronously. The conveying spiral blades 213 on the surface of the conveying shaft 218 push the aggregate to move along the inside of the soaking cylinder, thereby realizing the continuous conveying of the aggregate.

[0046] The aggregate passes through the first soaking cylinder 216, the second soaking cylinder 204, the third soaking cylinder 215, and the fourth soaking cylinder 217 in sequence. The four soaking cylinders adopt a "layered and interconnected" layout. The first soaking cylinder 216 and the second soaking cylinder 204 are at the same height, the third soaking cylinder 215 is located directly below the second soaking cylinder 204, and the fourth soaking cylinder 217 is located directly below the first soaking cylinder 216. All soaking cylinders are connected by the first material guide connecting pipe 214. This layout and connection method effectively extends the soaking path and time of the aggregate, ensuring that the aggregate is completely wetted and achieving the core purpose of "weakening water-force coupling". Meanwhile, the outlet size of each soaking tank is larger than the inlet size to avoid clogging of aggregates during transportation and ensure a continuous and smooth soaking process.

[0047] After being moistened, the aggregate finally enters the aggregate conveyor belt 203 through the outlet of the fourth soaking cylinder 217. The top of the aggregate conveyor belt 203 extends out of the protective shell 205 and is connected to the inlet at the top of the primary drying and sorting device 301, realizing the seamless connection between the soaking module 2 and the collision module 3, ensuring that the aggregate conveying is uninterrupted.

[0048] The protective shell 205 protects the entire soaking and conveying device, preventing water splashing and aggregate spillage. The two sets of second driven worm gears 202 at the top are protected by the protective cover 208 to prevent dust and impurities from entering the transmission structure, ensuring the normal operation of the drive components and extending the service life of the equipment.

[0049] Collision module 3 is the core area for aggregate crushing, drying, and sorting. It includes a primary drying and sorting device 301, a secondary drying device 302, a collision device 303, an auxiliary pneumatic device 304, and a tertiary sorting device 305. These components are connected in an orderly manner through material guide pipes, screw conveyors, etc., and work together sequentially to complete aggregate drying and sorting, two-stage directional collision crushing, and finished product sorting. The specific process is as follows: 1. Primary drying and sorting stage: The aggregate conveyor belt 203 transports the wet aggregate to the collection trough 30101 of the primary drying and sorting device 301. The collection trough 30101 evenly distributes the aggregate to several sets of drying and screening components at the bottom, ensuring that the aggregate enters the subsequent drying and screening process evenly and avoiding local accumulation that affects the drying and sorting effect.

[0050] The global control module 1 controls the second drive motor 30106 and the first heating wire 30111 to start. The second drive motor 30106 drives the first rotating rod 30112 to rotate. The first rotating rod 30112 drives the first screen cylinder 30113 and the first inner spiral blade 30114 and the first outer spiral blade 30115 on its surface to rotate synchronously. The first inner spiral blade 30114 pushes the aggregate to move inside the first screen cylinder 30113 to realize the continuous conveying of the aggregate. The first outer spiral blade 30115 stirs the aggregate screened between the drying screening inner cylinder 30110 and the first screen cylinder 30113 and discharges it through the corresponding first screening discharge pipe 30104. The global control module 1 controls the first heating wire 30111 to be energized to generate heat, which heats and dries the aggregate inside the drying and screening inner cylinder 30110. At the same time, the global control module 1 controls the first air intake fan 30105 to introduce cold air into the drying and screening inner cylinder 30110. The cold air is heated by the first heating wire 30111 and becomes hot air, which comes into full contact with the aggregate and removes the surface moisture of the aggregate, achieving the processing requirement of "saturated surface drying". This reduces the strength of the aggregate and increases its density, laying the foundation for subsequent directional impact crushing. The hot air is finally discharged through the first exhaust grille 30103, forming a thermal cycle and improving energy efficiency.

[0051] The first screen cylinder 30113 performs preliminary screening of the aggregate. Aggregates with particle sizes that do not meet the requirements are discharged through the first screening discharge pipe 30104 for subsequent recycling and reprocessing. Saturated surface-dry aggregates of similar particle sizes that meet the requirements are discharged through the discharge port of the bottom drying and screening outer cylinder 30102 and the third guide connecting pipe 30109 into the first-stage screw conveyor 30301, which then conveys them to the upper collision assembly of the collision device 303. Multiple sets of drying and screening assemblies are connected vertically through the second guide connecting pipe 30107 to ensure continuous aggregate conveying and improve processing efficiency.

[0052] 2. First-stage directional collision and fragmentation phase: The primary spiral conveyor 30301 transports saturated surface-dry aggregate to the upper drive belt 30303. The discharge port at the end of the upper drive belt 30303 is located directly above the feed hopper 30312 of the upper collision component, which can accurately feed the aggregate into the feed hopper 30312 of the upper collision component, avoid aggregate spillage, and ensure accurate supply of collision raw materials.

[0053] The global control module 1 controls the acceleration motor 30310 to start, which drives the long shaft 30311 to rotate. The long shaft 30311 drives the two sets of couplings 30313 at the same height to rotate synchronously. The driving gear 30314 at the bottom output end of the coupling 30313 meshes with the driven gear 30316 on the feed hopper 30312, thereby driving the feed hopper 30312 and the internal acceleration components to rotate, ensuring that the acceleration speed of the aggregate on the left and right sides is consistent, thus providing a guarantee for directional collision.

[0054] The upper and lower sets of rotating rings 30315 of the acceleration component drive the equally spaced acceleration plates 30317 to rotate at high speed, uniformly accelerating the aggregate entering the circular shell 30309, ensuring that the aggregate obtains uniform kinetic energy. Simultaneously, the auxiliary pneumatic device 304 is activated, and the gas generated by the air pump 30401 is stabilized by the pressure tank 30403 and then transported to the guide nozzle 30402 through the air guide pipe 30404. The guide nozzle 30402 is fixed to the outer end of the upper hollow guide channel 30304 and sprays gas out to the outer end, guiding the accelerated aggregate in the left and right circular shells 30309 to converge towards the middle, and finally directional collision occurs in the lower collision chamber 30308, using the kinetic energy of the aggregate itself to achieve crushing (the weakening effect of water has reduced the strength of the aggregate, which can reduce crushing energy consumption and avoid over-crushing).

[0055] After the collision, the aggregate enters the secondary drying device 302 through the sixth feed pipe 30208 at the bottom of the upper collision chamber 30305. The vent 30318 at the top of the upper collision chamber 30305 can discharge the dust and excess gas generated during the collision process, avoid excessive pressure inside the chamber, and ensure the safe operation of the equipment.

[0056] 3. Secondary drying stage: Aggregates entering the secondary drying unit 302 need to be completely dried to remove trace amounts of moisture that may have been adsorbed during the collision process, ensuring the effectiveness of the subsequent secondary collision crushing and avoiding moisture affecting the crushing precision and finished product quality of the aggregates.

[0057] The secondary drying device 302 includes a secondary drying shell 30201 and secondary drying inner cylinders 30207 distributed vertically inside the secondary drying shell 30201. The discharge port of the upper secondary drying inner cylinder 30207 and the inlet of the lower secondary drying inner cylinder 30207 are connected by a fourth material guide connecting pipe 30209, which can extend the drying path of aggregates and ensure thorough drying.

[0058] The global control module 1 controls the third drive motor 30202, the second heating wire 30213 and the second intake fan 30203 to work. The third drive motor 30202 drives the second rotating rod 30211 to rotate. The second rotating rod 30211 drives the second screen cylinder 30210 and the second inner spiral blade 30212 on the inner wall to rotate. The second inner spiral blade 30212 pushes the aggregate to move inside the secondary drying inner cylinder 30207 to achieve continuous drying. The second intake fan 30203 introduces cold air into the secondary drying shell 30201. The cold air is heated by the second heating wire 30213 and becomes hot air, which comes into full contact with the aggregate and removes the moisture from the aggregate. The hot air is discharged through the second exhaust grille 30204 at the other end of the secondary drying shell 30201 to ensure the drying effect.

[0059] After being fully dried, the aggregate enters the secondary screw conveyor 30302 through the fifth guide pipe 30206 at the bottom of the secondary drying shell 30201. The secondary screw conveyor 30302 then transports the aggregate to the lower collision assembly. The reserved slot 30205 on the secondary drying shell 30201 is used to connect to the bottom of the seventh guide pipe 30505 to ensure smooth subsequent finished product transport and avoid structural interference.

[0060] 4. Second-stage directional collision and fragmentation phase: The lower drive belt 30306, connected to both ends of the top discharge port of the secondary spiral elevator 30302, has its end discharge port located directly above the feed hopper 30312 of the lower collision component, accurately feeding the completely dried aggregate into the feed hopper 30312 of the lower collision component.

[0061] The driving structure of the lower collision component is exactly the same as that of the upper collision component. The acceleration motor 30310 drives the lower acceleration component to rotate through the meshing of the long shaft 30311, coupling 30313, driving gear 30314 and driven gear 30316, thereby accelerating the aggregate a second time. It should be noted that the rotational speed of the acceleration component of the lower collision assembly is lower than that of the acceleration component of the upper collision assembly. That is, the collision velocity of the saturated surface-dry aggregate to be crushed in the upper collision assembly is greater than that of the completely dry aggregate in the lower collision assembly. At the same time, the guide nozzle 30402 of the auxiliary pneumatic device 304 sprays gas out of the outer end of the hollow guide channel 30307 in the lower layer, guiding the accelerated aggregate in the circular shells 30309 on the left and right sides to converge in the middle, and a secondary directional collision occurs in the collision chamber 30308 in the lower layer, further refining the aggregate particle size and ensuring that the finished aggregate particle size meets the requirements.

[0062] The vent 30318 at the top of the lower collision chamber 30308 also serves to discharge dust and excess gas, ensuring stable operation of the equipment. The aggregate after collision enters the three-stage sorting device 305 through the seventh guide pipe 30505.

[0063] 5. Three-stage sorting: The three-stage sorting device 305 is used to perform final screening of the aggregates after the secondary collision, separating the finished aggregates that meet the requirements from the impurities or coarse materials that do not meet the requirements.

[0064] The global control module 1 controls the fourth drive motor 30502 to start. The fourth drive motor 30502 drives the third rotating rod to rotate. The third rotating rod drives the third screen cylinder and the third inner spiral blade on the inner wall to rotate. The third inner spiral blade pushes the aggregate to move inside the third screen cylinder. The third screen cylinder performs precise screening of the aggregate. The finished aggregate that meets the requirements is output through the finished product conveyor belt 30504 at the bottom of the discharge port of the three-stage sorting shell 30501, which is convenient for subsequent collection and use. The coarse material or impurities that do not meet the requirements are discharged through the second screening discharge pipe 30503 at the bottom of the other end of the three-stage sorting shell 30501, realizing the separation of finished product and waste material and improving the finished product qualification rate.
