Description

Technical Field

[0001] This invention relates to the field of construction waste recycling, and in particular to a system and method for recycling and utilizing construction waste. Background Technology

[0002] In the construction of underground engineering projects such as pile foundations and diaphragm walls, a large amount of slag with complex composition and variable properties is generated. Currently, the mainstream treatment methods for this type of slag are still mainly sedimentation, screening, and small-scale backfilling or direct disposal, resulting in low resource utilization rates and problems such as environmental pollution and land occupation. Existing recycling technologies, such as using fixed proportions to solidify slag into backfill materials, have some effect, but generally face two key bottlenecks: First, the processing technology is mostly intermittent, unable to achieve continuous and efficient dehydration and transfer of slag, thus limiting overall processing efficiency; second, because it fails to identify and adapt to the fluctuations in the moisture content and composition of the slag itself in real time, using fixed formulas makes it difficult to consistently guarantee the product quality of recycled building materials, and easily leads to waste or insufficient cementitious materials, resulting in unsatisfactory economic efficiency and reliability. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that existing slag recycling technologies are unable to achieve intelligent adaptation and precise batching of slag with fluctuating composition while ensuring continuous and efficient processing, resulting in a tradeoff between efficiency, quality and cost.

[0004] The above-mentioned technical problems are solved by the following technical solution: This invention proposes a waste soil recycling and utilization system, which includes, At least two sets of filter cake discharge equipment, each set of filter cake discharge equipment includes a basket, a mounting frame fixedly connected to the top of the basket, a centrifugal vibrator set at the top of the mounting frame, a bottom door hinged to the bottom of the basket, and a moisture content sensor set at the bottom of the inner wall of the basket. The support frame has a hanging component fixedly connected to its outer side, a steel rail is provided on the inner side of the hanging component, and guide plates are fixedly connected to both sides of the steel rail. The filter residue discharge device is slidably connected to the steel rail and can move along it. A mud conveying device for conveying mud to be treated to the filter residue discharge device; The mixing equipment, based on the moisture content detected by the moisture content sensor, proportions and mixes the received slag and soil. Specifically, the mud conveying equipment continuously pumps the mud generated from underground construction into a basket located at the slag filtering station. After the centrifugal vibrator is activated, the mud achieves rapid solid-liquid separation under vibration. Water is filtered out through the screen holes of the basket, while the slag remains inside. A moisture content sensor installed at the bottom of the inner wall of the basket can detect the moisture content of the dewatered slag in real time and output this key data. The mixing equipment receives this moisture content data and uses it to intelligently proportion and mix the subsequently received slag, thereby transforming the slag with varying composition and properties into building materials with controllable quality. By setting at least two sets of slag filtering and slag discharge equipment to circulate on the steel rails of the support, continuous alternating operation of the slag filtering and slag discharge processes is achieved, effectively avoiding the waiting time of single-equipment operation and significantly improving the overall processing efficiency.

[0005] In a preferred embodiment of the waste soil recycling system of the present invention: the mounting frame includes a base plate, a hanging rod fixedly connected to the bottom end of the base plate, and a cross connecting rod fixedly connected to the outside of the hanging rod; the centrifugal vibrator is disposed at the top of the base plate, and the cross connecting rod is fixedly connected to the basket; Specifically, the centrifugal vibrator is fixed to the top of the base plate, and the vibration force it generates is efficiently transmitted to the basket through the base plate, the suspension rod, and the cross link, driving the entire basket to vibrate stably. The multi-point fixed connection between the cross link and the top of the basket ensures the symmetry of the vibration energy distribution, preventing the basket from swaying or twisting during high-speed vibration, thereby ensuring the uniformity of the dehydration effect and the stability of the equipment operation.

[0006] In a preferred embodiment of the waste soil recycling system of the present invention: an opening and closing motor is provided at the bottom end of the boom, a hinge wheel is fixedly connected to the output end of the opening and closing motor, a steel wire is provided on the outside of the hinge wheel, and one end of the steel wire is connected to the bottom door; Specifically, when slag discharge is required, the opening and closing motor drives the hinge wheel to rotate and release the steel wire. Under the weight of the slag, the bottom door flips downwards around the hinge point and opens, achieving rapid slag discharge. After slag discharge is completed, the opening and closing motor reverses, and the bottom door is pulled back and closed by rewinding the steel wire, preparing for the next round of slag filtering operations. In a preferred embodiment of the waste soil recycling system of the present invention: a roller is installed at the bottom end of the base plate, a drive motor is fixedly connected inside the lifting rod, a universal joint is connected to the output end of the drive motor, the other end of the universal joint is connected to the rotating shaft of the roller, and a ball bearing is provided between the roller and the base plate. Specifically, the drive motor can be started by driving the rollers to roll on the rails via the universal joint, thereby moving the entire suspended platform. The design of the universal joint ensures smooth power transmission. The ball bearing design allows the rollers to rotate freely in the horizontal plane relative to the base plate, thus enabling the device to move flexibly along the rails.

[0007] In a preferred embodiment of the waste soil recycling system of the present invention: a power supply component is provided on the outside of the rail, which includes a brush disposed on the outside of the rail, a wire located between the brush and the guide plate, and a spring disposed on the outside of the brush; Specifically, current is introduced through the contact point between the brush and the wire to power the equipment. This sliding power supply method eliminates the need for dragging cables and avoids the problem of cable tangling and wear.

[0008] In a preferred embodiment of the waste soil recycling system of the present invention: the mud conveying equipment includes a drilling motor, a drill rod disposed at the output end of the drilling motor, a drill bit disposed at the bottom end of the drill rod, a circulation pipeline for circulating mud, a conveying pipeline for conveying mud to the filter slag discharge equipment, and a recovery tank for recovering mud. The circulation pipeline includes a circulation pipe, a circulation pump installed on the circulation pipe, and a one-way valve. The two ends of the circulation pipe are connected to the drill pipe and the mud circulation pool, respectively. The delivery pipeline includes a delivery pipe, a delivery pump installed on the delivery pipe, and a one-way valve. One end of the delivery pump is located in the mud circulation tank, and the other end is located at the top of the basket. The recovery tank is located at the bottom of the suspended boiler station and is connected to the mud circulation tank through a return pipe; Specifically, the drilling rig motor drives the drill rod and drill bit to rotate and impact for hole formation; the circulation pump pumps the mud from the mud circulation tank into the drill rod cavity, which is then sprayed out from the drill bit to cool the drill bit and carry rock cuttings. The mud carrying rock cuttings returns to the ground along the annular gap of the borehole wall and finally flows back to the mud circulation tank, completing one cycle; the mud is then pumped by a delivery pump to a basket located at the slag filtering station for dewatering treatment; the mud-water filtered from the screen holes of the basket falls into a recycling tank set below it and returns to the mud circulation tank for reuse through a return pipe, realizing a closed-loop water resource circulation and reducing wastewater discharge.

[0009] In a preferred embodiment of the waste soil recycling system of the present invention: the mixing equipment includes a cement tower, an aggregate tower and a mixing chamber, and the output ends of the cement tower and the aggregate tower are respectively equipped with metering switches; The mixing chamber is equipped with a mixing motor. The slag, soil, cementitious materials and aggregate mixture are conveyed by a conveyor belt. The slag, cementitious materials and aggregate mixture enters the brick making machine and is made into bricks. Specifically, based on the moisture content data of the slag detected and uploaded by the moisture content sensor, the control system determines the slag type and calculates the appropriate ratio of cementitious materials and aggregates. Subsequently, the control system precisely controls the opening and timing of the metering switches at the bottom of the cement tower and aggregate tower, adding a fixed amount of cementitious materials and aggregates into the mixing chamber. The dehydrated slag is then conveyed into the mixing chamber via a conveyor belt. The mixing motor drives the mixing mechanism within the mixing chamber to thoroughly mix the slag, cementitious materials, and aggregates, forming a homogeneous mixture. This mixture is then conveyed to a brick-making machine via a conveyor belt and pressed into building bricks.

[0010] This invention also provides a treatment system and method for the recycling and utilization of construction waste, which includes the following steps: At least two sets of filter residue discharge equipment are used to operate alternately along the circulation track; The slurry is transported to the basket of the filter cake discharge equipment located at the filter cake station; Start the centrifugal vibrator to vibrate and dewater the mud in the basket; The moisture content of the dehydrated slag was detected using a moisture content sensor; Based on the detected moisture content, control the metering switches of the cement tower and aggregate tower in the mixing equipment to output the corresponding proportion of cementitious materials and aggregates to the mixing chamber; The dehydrated slag is discharged from the basket into the mixing chamber, where it is mixed with cementitious materials and aggregates to form a mixture. The mixture is pressed into building bricks; Specifically, firstly, by alternating movement and operation of at least two sets of filter residue discharge equipment on a circular track, seamless spatial and temporal integration of the filter residue and discharge processes is achieved, ensuring the continuity of the slurry treatment process and significantly improving processing efficiency. Based on real-time intelligent proportioning control, after vibration dewatering, the moisture content of the slag is immediately acquired online via a moisture sensor. Based on this moisture content data, the slag category is automatically determined, and a pre-set optimal ratio of cementitious materials and aggregates matching that category is invoked. Subsequently, the control system instructs the metering switches of the cement tower and aggregate tower in the mixing equipment to precisely dispense materials according to this ratio. Finally, the dewatered slag and ingredients are uniformly mixed in the mixing chamber and pressed into bricks.

[0011] In a preferred embodiment of the waste soil recycling system method of the present invention: the step of controlling the metering switch according to the detected moisture content is as follows: The detected moisture content is compared with a preset first threshold and a second threshold; If the moisture content is lower than the first threshold, the slag will be classified as Class I, and the metering switch will be controlled to discharge the material according to the first cementitious material dosage ratio and the first aggregate dosage ratio. If the moisture content is between the first threshold and the second threshold, the slag will be classified as the second type, and the metering switch will be controlled to discharge the slag according to the second cementitious material dosage ratio and the second aggregate dosage ratio. If the moisture content is higher than or equal to the second threshold, the slag will be classified as the third category, and the metering switch will be controlled to discharge the slag according to the third cementitious material content ratio and the third aggregate content ratio. Specifically, by setting a first threshold W1 and a second threshold W2 for moisture content, the complex composition of slag soil is scientifically divided into three categories. Slag soil with a moisture content lower than W1 typically indicates coarser particles, fewer hydrophilic minerals, and lower water demand, and is therefore classified as Category I. It can be mixed using a lower proportion of the first cementitious material and a higher proportion of the first aggregate to ensure brick strength while saving cement usage. Slag soil with a moisture content between W1 and W2 has intermediate characteristics and is classified as Category II, using a moderate proportion of the second aggregate. Slag soil with a moisture content higher than or equal to W2 indicates finer particles, more hydrophilic minerals, and higher water demand, and is classified as Category III. It requires a higher proportion of the third cementitious material and a potentially adjustable proportion of the third aggregate to ensure brick strength and workability.

[0012] In a preferred embodiment of the waste soil recycling and treatment system method of the present invention, the following steps are also included: Sampling and testing of the manufactured building bricks are conducted, and the strength test results are fed back to the control system. Based on the strength test results, the moisture content threshold and the ratio of cementitious materials to aggregates for the classification of construction waste were optimized and adjusted. Specifically, the actual quality inspection results are fed back to the intelligent control system, where the built-in optimization algorithm compares and analyzes these results against the expected targets. If the strength of a certain type of brick continues to deviate from the standard, the system can automatically fine-tune the moisture content classification threshold corresponding to that type of slag, or optimize the ratio of cementitious materials to aggregates to ensure the quality of the finished bricks.

[0013] The beneficial effects of this invention are as follows: By alternating operation of at least two sets of filter residue discharge equipment on a circulating track, continuous and uninterrupted operation of the filter residue, dewatering, and slag discharge processes is achieved, significantly improving processing efficiency; Based on real-time online detection of dewatered slag by a moisture content sensor, and the automatic classification and precise batching of the intelligent control system based on the detection data and preset thresholds, personalized and optimized resource utilization of slag with varying compositions is achieved, saving cementitious material costs while ensuring that the strength of the finished bricks meets the standards; Finally, by feeding back the strength test results of the finished bricks to the system and automatically optimizing the classification thresholds and proportioning parameters, an adaptive closed-loop quality control is formed, ensuring the long-term stability of product quality.

Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0024] Reference Figures 1-7 This embodiment provides a waste soil recycling system proposed in this invention, which includes: At least two sets of filter cake discharge equipment 1, each set of filter cake discharge equipment 1 includes a basket 11, a mounting frame 12 fixedly connected to the top of the basket 11, a centrifugal vibrator 13 set at the top of the mounting frame 12, a bottom door 14 hinged to the bottom of the basket 11, and a moisture content sensor 15 set at the bottom of the inner wall of the basket 11. The support 2 has a hanging component 21 fixedly connected to its outer side, a steel rail 22 is provided on the inner side of the hanging component 21, and guide plates 23 are fixedly connected to both sides of the steel rail 22. The filter residue discharge device 1 is slidably connected to the steel rail 22 and can move along it. Slurry conveying equipment 3 is used to convey slurry to be treated to filter residue discharge equipment 1; The mixing device 4, based on the moisture content detected by the moisture content sensor 15, proportions and mixes the received slag and soil. Specifically, the mud conveying equipment 3 continuously pumps the mud generated from underground construction into the basket 11 located at the slag filtering station. After the centrifugal vibrator 13 is started, the mud achieves rapid solid-liquid separation under vibration. Water is filtered out through the screen holes of the basket 11, while the slag remains in the basket. The moisture content sensor 15, installed at the bottom of the inner wall of the basket 11, can detect the moisture content of the dewatered slag in real time and output this key data. The mixing equipment 4 receives this moisture content data and uses it to intelligently proportion and mix the subsequently received slag, thereby transforming the slag with varying composition and properties into building materials with controllable quality. By setting at least two sets of slag filtering and slag discharge equipment 1 to circulate on the steel rails 22 of the support 2, continuous alternating operation of the slag filtering and slag discharge processes is achieved, effectively avoiding the waiting time when operating a single piece of equipment and significantly improving the overall processing efficiency.

[0025] The mounting frame 12 includes a base plate 121, a hanging rod 122 fixedly connected to the bottom end of the base plate 121, and a cross link 123 fixedly connected to the outside of the hanging rod 122; the centrifugal vibrator 13 is set at the top of the base plate 121, and the cross link 123 is fixedly connected to the basket 11. Specifically, the centrifugal vibrator 13 is fixed to the top of the base plate 121. The vibration force it generates is efficiently transmitted to the basket 11 through the base plate 121, the hanging rod 122, and the cross link 123, driving the entire basket 11 to vibrate stably. The multi-point fixed connection between the cross link 123 and the top of the basket 11 ensures the symmetry of the vibration energy distribution and prevents the basket 11 from swaying or twisting during high-speed vibration, thereby ensuring the uniformity of the dehydration effect and the stability of the equipment operation.

[0026] An opening and closing motor 141 is provided at the bottom end of the boom 122. A hinge wheel 142 is fixedly connected to the output end of the opening and closing motor 141. A steel wire 143 is provided on the outside of the hinge wheel 142. One end of the steel wire 143 is connected to the bottom door 14. Specifically, when slag discharge is required, the opening and closing motor 141 drives the hinge wheel 142 to rotate and release the steel wire 143. Under the weight of the slag, the bottom door 14 flips downward around the hinge point and opens, achieving rapid slag discharge. After slag discharge is completed, the opening and closing motor 141 reverses, and the steel wire 143 is wound up to pull the bottom door 14 back and close, preparing for the next round of slag filtering operation. A roller 16 is installed at the bottom end of the base plate 121. A drive motor 161 is fixedly connected inside the rod 122. The output end of the drive motor 161 is connected to a universal joint 162. The other end of the universal joint 162 is connected to the shaft of the roller 16. A ball bearing 163 is provided between the roller 16 and the base plate 121. Specifically, the start of the drive motor 161 can drive the roller 16 to roll on the rail 22 through the universal joint 162, thereby moving the entire basket 11. The design of the universal joint 162 ensures smooth power transmission. The design of the ball bearing 163 allows the roller 16 to rotate freely in the horizontal plane relative to the base plate 121, thereby allowing the device to move flexibly along the rail 22.

[0027] A power supply component 24 is provided on the outside of the rail 22, which includes a brush 241 provided on the outside of the rail 22, a wire 242 located between the brush 241 and the guide plate 23, and a spring 243 provided on the outside of the brush 241. Specifically, current is introduced through the contact point between the brush 241 and the wire 242 to power the equipment. This sliding power supply method eliminates the need for dragging cables and avoids the problem of cable tangling and wear.

[0028] The mud conveying equipment 3 includes a drilling motor 31, a drill rod 32 located at the output end of the drilling motor 31, a drill bit 33 located at the bottom end of the drill rod 32, a circulation pipeline 34 for circulating mud, a conveying pipeline 35 for conveying mud to the filter residue discharge equipment 1, and a recovery tank 36 for recovering mud. The circulation pipeline 34 includes a circulation pipe, a circulation pump installed on the circulation pipe, and a check valve. The two ends of the circulation pipe are connected to the drill pipe 32 and the mud circulation pool, respectively. The delivery pipeline 35 includes a delivery pipe, a delivery pump installed on the delivery pipe, and a check valve. One end of the delivery pump is located in the mud circulation tank, and the other end is located at the top of the basket 11. The recovery tank 36 is located at the bottom of the boiler station of the suspended basket 11 and is connected to the mud circulation tank through a return pipe; Specifically, the drilling rig motor 31 drives the drill rod 32 and drill bit 33 to rotate and impact for hole formation. The circulation pump pumps the mud from the mud circulation tank into the inner cavity of the drill rod 32, and sprays it out from the drill bit 33 to cool the drill bit 33 and carry the rock cuttings. The mud carrying the rock cuttings returns to the ground along the annular gap of the hole wall and finally flows back to the mud circulation tank, completing one cycle. The mud is pumped to the basket 11 at the filter position by the delivery pump for dewatering treatment. The mud water filtered from the screen of the basket 11 falls into the recovery tank 36 set below it and returns to the mud circulation tank for reuse through the return pipe, realizing a closed-loop circulation of water resources and reducing wastewater discharge.

[0029] The mixing equipment 4 includes a cement tower 41, an aggregate tower 42, and a mixing chamber 43. The output ends of the cement tower 41 and the aggregate tower 42 are respectively equipped with metering switches. The mixing chamber 43 is equipped with a mixing motor 44. The slag and the mixture of slag, cementitious materials and aggregates are conveyed by the conveyor belt 5. The mixture of slag, cementitious materials and aggregates enters the brick making machine 6 and is made into bricks. Specifically, based on the moisture content data of the slag detected and uploaded by the moisture content sensor 15, the control system determines the type of slag and calculates the appropriate ratio of cementitious materials and aggregates accordingly. Subsequently, the control system precisely controls the opening and timing of the metering switches at the bottom of the cement tower 41 and aggregate tower 42, adding a fixed amount of cementitious materials and aggregates into the mixing chamber 43. The dehydrated slag is then conveyed into the mixing chamber 43 via the conveyor belt 5. The mixing motor 44 drives the mixing mechanism within the mixing chamber 43 to thoroughly mix the slag, cementitious materials, and aggregates, forming a homogeneous mixture. This mixture is then conveyed to the brick-making machine 6 via the conveyor belt 5 and pressed into building bricks.

[0030] In summary, firstly, the conveying pipeline 35 continuously pumps the slurry into the basket 11 of a set of slag discharge equipment 1 that is currently in the slag discharge station; then, the centrifugal vibrator 13 fixed to the top of the bottom plate 121 is started, and the vibration force generated by it is rigidly transmitted to the basket 11 through the hanging rod 122 and the cross connecting rod 123, driving it to vibrate at high speed, forcing the water in the slurry to be quickly filtered out through the screen holes on the wall of the basket 11, thus achieving efficient dewatering of the slag; during the dewatering process, the moisture content sensor 15 set at the bottom of the inner wall of the basket 11 detects the moisture content of the slag in real time. Once dewatering is complete, the drive motor 161 starts, driving the roller 16 to roll on the rail 22 via the universal joint 162. Guided by the guide plate 23, the entire equipment is moved to the slag discharge station. At this time, the opening and closing motor 141 at the bottom of the boom 122 is activated, driving the hinge wheel 142 to release the steel wire 143, causing the bottom door 14, hinged to the bottom of the basket 11, to open under the weight of the slag, and the dewatered slag is discharged. Simultaneously, another set of filter slag discharge equipment 1 has moved to the filter slag station and begun receiving slurry. The two sets of equipment work alternately on the circular rail 22, with the brush 241 maintaining contact with the wire 242 under the action of the spring 243 to supply power. This achieves continuous and uninterrupted operation of the filter slag, dewatering, and slag discharge processes, significantly improving the system's processing efficiency. The discharged dewatered slag is conveyed to the mixing chamber 43 of the mixing equipment 4 via conveyor belt 5. Based on the real-time data uploaded by the moisture content sensor 15, the intelligent control system determines the type of slag and precisely controls the opening degree and time of the metering switches at the bottom of the cement tower 41 and the aggregate tower 42 to quantitatively add cementitious materials and aggregates into the mixing chamber 43. The mixing motor 44 in the mixing chamber 43 starts to fully mix the slag, cementitious materials and aggregates to form a homogeneous mixture. The mixture is finally conveyed to the brick making machine 6 via conveyor belt 5 and pressed into building bricks.

[0031] As one embodiment provided, such as Figures 1-7 A method for a waste soil recycling and utilization system, comprising the following steps: At least two sets of filter residue discharge equipment are used to operate alternately along the circulation track; The slurry is transported to the basket of the filter cake discharge equipment located at the filter cake station; Start the centrifugal vibrator to vibrate and dewater the mud in the basket; The moisture content of the dehydrated slag was detected using a moisture content sensor; Based on the detected moisture content, control the metering switches of the cement tower and aggregate tower in the mixing equipment to output the corresponding proportion of cementitious materials and aggregates to the mixing chamber; The dehydrated slag is discharged from the basket into the mixing chamber, where it is mixed with cementitious materials and aggregates to form a mixture. The mixture is pressed into building bricks; Specifically, firstly, by alternating movement and operation of at least two sets of filter residue discharge equipment on a circular track, seamless spatial and temporal integration of the filter residue and discharge processes is achieved, ensuring the continuity of the slurry treatment process and significantly improving processing efficiency. Based on real-time intelligent proportioning control, after vibration dewatering, the moisture content of the slag is immediately acquired online via a moisture sensor. Based on this moisture content data, the slag category is automatically determined, and a pre-set optimal ratio of cementitious materials and aggregates matching that category is invoked. Subsequently, the control system instructs the metering switches of the cement tower and aggregate tower in the mixing equipment to precisely dispense materials according to this ratio. Finally, the dewatered slag and ingredients are uniformly mixed in the mixing chamber and pressed into bricks.

[0032] The specific steps for controlling the metering switch based on the detected moisture content are as follows: The detected moisture content is compared with a preset first threshold and a second threshold; If the moisture content is lower than the first threshold, the slag will be classified as Class I, and the metering switch will be controlled to discharge the material according to the first cementitious material dosage ratio and the first aggregate dosage ratio. If the moisture content is between the first threshold and the second threshold, the slag will be classified as the second type, and the metering switch will be controlled to discharge the slag according to the second cementitious material dosage ratio and the second aggregate dosage ratio. If the moisture content is higher than or equal to the second threshold, the slag will be classified as the third category, and the metering switch will be controlled to discharge the slag according to the third cementitious material content ratio and the third aggregate content ratio. Specifically, by setting a first threshold W1 and a second threshold W2 for moisture content, the complex composition of slag soil is scientifically divided into three categories. Slag soil with a moisture content lower than W1 typically indicates coarser particles, fewer hydrophilic minerals, and lower water demand, and is therefore classified as Category I. It can be mixed using a lower proportion of the first cementitious material and a higher proportion of the first aggregate to ensure brick strength while saving cement usage. Slag soil with a moisture content between W1 and W2 has intermediate characteristics and is classified as Category II, using a moderate proportion of the second aggregate. Slag soil with a moisture content higher than or equal to W2 indicates finer particles, more hydrophilic minerals, and higher water demand, and is classified as Category III. It requires a higher proportion of the third cementitious material and a potentially adjustable proportion of the third aggregate to ensure brick strength and workability.

[0033] It also includes the following steps, Sampling and testing of the manufactured building bricks are conducted, and the strength test results are fed back to the control system. Based on the strength test results, the moisture content threshold and the ratio of cementitious materials to aggregates for the classification of construction waste were optimized and adjusted. Specifically, the actual quality inspection results are fed back to the intelligent control system, where the built-in optimization algorithm compares and analyzes these results against the expected targets. If the strength of a certain type of brick continues to deviate from the standard, the system can automatically fine-tune the moisture content classification threshold corresponding to that type of slag, or optimize the ratio of cementitious materials to aggregates to ensure the quality of the finished bricks.

[0034] In summary, by utilizing at least two sets of filter cake discharge equipment that move and operate alternately along a circulating track, when one set of equipment is at the filter cake station receiving and processing slurry, the other set can simultaneously move to the discharge station to discharge the slag, achieving seamless spatial and temporal integration and continuous operation of the filter cake, dewatering, and discharge processes, thus significantly improving the overall processing efficiency of the system. Furthermore, a moisture content sensor installed at the bottom of the inner wall of the basket continuously monitors the real-time moisture content of the dewatered slag. Based on this monitoring data, the intelligent control system classifies and proportions the materials, achieving precise addition of cementitious materials and aggregates, optimizing material costs while ensuring the final brick product meets strength standards.

[0035] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
