Description

Technical Field

[0001] This invention relates to the field of construction waste treatment, specifically a high-pressure, fast-spraying, dead-angle-free mixing production line for treating construction waste. Background Technology

[0002] Construction waste is increasingly being generated from engineering projects. The national annual output of construction waste exceeds 1 billion tons and continues to grow year by year. Construction waste is generally difficult to utilize directly, especially the silty clay in coastal areas, which is characterized by high water content, high compressibility, high sensitivity, and low strength, making it difficult to decompose and mix. To solve the problem of construction waste disposal and transform it into green building materials, an industrialized, large-scale treatment method and streamlined production line are needed.

[0003] Traditional methods of treating construction waste have three major problems: first, insufficient treatment capacity, making it difficult to dispose of on a large scale; second, poor economic efficiency, with high treatment costs and low cost-effectiveness of materials after resource recovery, making them difficult to be accepted by the market; and third, the total amount of construction waste is too large, requiring a sufficiently large market to absorb the resource recovery products.

[0004] To address the efficiency issues in construction waste disposal and transform it into other materials that can be used on a large scale, a treatment line and method were introduced. By turning the construction waste into liquid-solidified soil, the problems of silt and construction waste adhesion and difficulty in treatment were solved. Summary of the Invention

[0005] To address the problems in the existing technology, the present invention provides a high-pressure, fast-spraying, dead-angle-free mixing production line for the treatment of construction waste.

[0006] The technical solution adopted by this invention to solve its technical problem is: a high-pressure, fast-spraying, dead-angle-free mixing construction waste treatment production line, including a base frame, unloading hopper, crushing mechanism, conveying frame, conveying mechanism, batching hopper, solidified slurry tank, mixing mechanism, collection hopper, and support legs. The base frame is uniformly equipped with support legs at its lower end. The unloading hopper is fixedly installed on the rear side of the upper end of the base frame. The crushing mechanism is installed at the lower end of the unloading hopper and is connected to the crushing mechanism. The conveying frame is fixedly installed on the upper end of the base frame. The conveying mechanism is installed on the conveying frame. The collection hopper is fixedly installed on the front side of the upper end of the base frame. The mixing mechanism is installed at the upper end of the collection hopper and is connected to the collection hopper. The batching hopper is installed on the mixing mechanism and is connected to the batching hopper. One end of the conveying mechanism is located below the crushing mechanism, and the other end of the conveying mechanism is located above the batching hopper. The solidified slurry tank is set in the middle of the base frame and is connected to the mixing mechanism through a grouting hose.

[0007] The mixing mechanism includes a mixing chamber, a mixing shaft, mixing blades, a mixing motor, a second synchronous pulley, a second synchronous belt, a discharge trough, a grouting pipe, and grouting nozzles. The mixing chamber is fixedly installed at the upper end of the collection silo, and the upper end of the mixing chamber is connected to the batching silo. The mixing shaft is symmetrically installed at the lower end of the mixing chamber via bearings, and mixing blades are fixedly installed on the mixing shaft. A second synchronous pulley is installed at one end of the mixing shaft via a key connection, and adjacent second synchronous pulleys are connected by a second synchronous belt. The mixing motor is fixedly installed on the side wall of the mixing chamber via a motor mount, and the output shaft of the mixing motor is connected to one of the mixing shafts. A grouting pipe is installed in the middle of the mixing chamber, and one end of the grouting pipe is connected to a grouting hose. Grouting nozzles are evenly arranged at the lower end of the grouting pipe. Through the opposing rotation of the two mixing blades, the slag on both sides of the waist-shaped trough can be continuously rolled and flowed in multiple directions while being mixed. This allows the slag to flow horizontally and further roll vertically, improving the mixing effect of the slag.

[0008] Specifically, the lower end of the mixing chamber has a waist-shaped structure with the bottom of the waist-shaped structure protruding upwards. Spring rods are evenly installed at the lower end of the mixing chamber. The spring rods are located between the mixing blades and correspond one-to-one with the grouting nozzles. A conical ball with inclined surfaces at both the upper and lower ends is fixedly installed at the movable end of the spring rod. The solidified slurry is evenly sprayed into the flowing slag and soil through the grouting nozzles set in multiple positions to form fluidized concrete reinforced soil. The solidified slurry can be evenly dispersed in all directions by the vibration of the conical ball and its inclined surface, further improving the contact and mixing effect between the solidified slurry and the slag and soil.

[0009] Specifically, the stirring blades are spiral blades, with only the two ends of the spiral blades connected to the stirring shaft, and the spiral blades located on both sides of the waist-shaped groove opening rotate in opposite directions.

[0010] Specifically, a discharge shaft is installed in the discharge trough by a rotatable engagement. The discharge shaft has a discharge port in the middle that matches the discharge trough. A discharge pointer is installed at one end of the discharge shaft by a key connection. One end of the discharge pointer is connected to the side wall of the mixing chamber by a discharge spring. A discharge cylinder is fixedly installed at the upper end of the side wall of the mixing chamber. A receiving slide is fixedly installed at the bottom of the side wall of the mixing chamber. An extrusion rod is installed at the upper end of the receiving slide by a sliding engagement. The upper end of the extrusion rod has a cross-shaped structure. The extrusion rod is located between symmetrically arranged discharge pointers and its upper end is connected to the discharge cylinder by a drive connection.

[0011] Specifically, an air compressor is fixedly installed at the middle of the upper end of the base frame, and the output port of the air compressor is connected to the curing slurry tank through a hose. A grouting pump is fixedly installed at the middle of the upper end of the base frame, and the grouting pump is connected to the grouting hose at the output port of the curing slurry tank.

[0012] Specifically, the conveying mechanism includes a conveying shaft, a conveyor belt, a conveyor motor, and guide shafts. The conveying shafts are symmetrically installed at both ends of the conveying frame via bearings, and the conveyor belt is sleeved between the conveying shafts. Two sets of guide shafts are symmetrically installed at both ends of the conveying frame. The two guide shafts in the same set are located on the inner and outer sides of the conveyor belt, respectively, and the length of the guide shaft on the outer side of the conveyor belt is shorter than the length of the guide shaft on the inner side of the conveyor belt.

[0013] Specifically, damping strips are evenly distributed on the conveyor belt, and a guide plate is fixedly installed on the upper end of the conveyor frame. The guide plate is located between the conveyor belt and the batching bin. The guide plate facing the batching bin has a downward inclined surface, and a scraper is installed on the guide plate facing the conveyor belt. The blade of the scraper rests against the outer sidewall of the conveyor belt. The damping strips on the conveyor belt can further support and separate the slag. Through the friction caused by the weight of the slag and the separating effect of the damping strip, the slag can be tightly adhered to the sidewall of the conveyor belt, reducing the probability of slag spillage and falling due to the flexible vibration of the conveyor belt itself, and also reducing dust generation. The scraper on the upper end of the guide plate can scrape and clean the slag adhering to the conveyor belt. When the scraper slides over the damping strip, the vibration caused by the damping strip can accelerate the falling rate of the mud strips accumulated on the guide plate, avoiding the backflow of slag and pollution of the surrounding environment of the production line.

[0014] Specifically, the crushing mechanism includes a crushing chamber, crushing rollers, crushing discs, crushing gears, a first synchronous pulley, and a first synchronous belt. The crushing chamber is fixedly installed at the lower end of the unloading chamber and is connected to it. Scraping teeth are evenly arranged on the front and rear side walls at the lower end of the crushing chamber, and the scraping teeth are located above the damping strips. Crushing rollers are symmetrically installed in the crushing chamber through bearings. Crushing discs are evenly installed on the crushing rollers through key connections. A crushing gear is installed at one end of the crushing roller through a key connection, and two adjacent crushing gears mesh with each other for transmission. A first synchronous pulley is symmetrically installed at one end of one crushing roller and one end of one conveying shaft through a key connection, and the synchronous pulley on the crushing roller and the synchronous pulley on the conveying shaft are connected by a first synchronous belt for transmission.

[0015] Specifically, the lower end of the batching silo is provided with a discharge port that communicates with the mixing silo. A discharge valve is installed at the discharge port by means of sliding fit. The discharge valve is sealed to the discharge port. A discharge cylinder is fixedly installed on the side wall of the batching silo, and the output shaft of the discharge cylinder is connected to the discharge valve in a driving connection.

[0016] Specifically, the bottom of the collection silo is provided with a loading valve port, which is connected and cooperates with the existing transport pump truck. The bottom side of the collection silo is provided with a pipe interface, which is connected to the existing silo through the existing pipeline.

[0017] The beneficial effects of this invention are:

[0018] (1) The high-pressure fast spraying and dead-angle mixing construction waste treatment production line of the present invention can continuously increase the density of loosely piled construction waste per unit volume through the joint squeezing action of crushing discs and crushing rollers, and its self-weight also increases accordingly. During the subsequent conveyor belt lifting and transportation process, the damping strips set on the conveyor belt can further support and separate the construction waste. Through the friction caused by the self-weight of the construction waste and the separation effect of the damping strips, the construction waste can be tightly attached to the side wall of the conveyor belt, reducing the probability of the construction waste spilling and falling due to the flexible vibration of the conveyor belt itself, improving the disposal and treatment capacity of large-scale construction waste, and also reducing the generation of dust.

[0019] (2) The high-pressure fast spraying and dead-angle mixing construction waste treatment production line of the present invention has a scraper blade set on the upper end of the guide plate to scrape and clean the residual soil adhering to the conveyor belt. When the scraper blade slides over the damping strip, the vibration caused by the damping strip can accelerate the falling rate of the mud strips accumulated on the guide plate, avoid the backflow of the soil and cause pollution and waste to the surrounding environment of the production line, and improve the economy.

[0020] (3) The high-pressure fast spraying construction waste treatment production line of the present invention, through the opposing rotation of two mixing blades, can make the waste on both sides of the waist-shaped trough continuously tumble and flow in multiple directions while mixing the waste. It can make the waste flow in the horizontal direction and further tumble in the vertical direction, thereby improving the mixing effect of the waste. The solidified slurry is evenly sprayed into the flowing waste through the grouting nozzles set in multiple positions to form fluid concrete reinforced soil. The solidified slurry can be evenly dispersed in all directions by the vibration of the conical ball and its inclined surface, thereby further improving the contact mixing effect between the solidified slurry and the waste.

Detailed Implementation

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] See Figure 1 and Figure 2 A high-pressure, fast-spraying, dead-angle-free mixing production line for treating construction waste includes a base frame 1, a discharge bin 2, a crushing mechanism 3, a conveyor frame 4, a conveying mechanism 5, a batching bin 6, a solidified slurry tank 7, a mixing mechanism 8, a collection bin 9, and support legs 10. Support legs 10 are evenly installed at the lower end of the base frame 1. The discharge bin 2 is fixedly installed on the rear side of the upper end of the base frame 1. The crushing mechanism 3 is installed at the lower end of the discharge bin 2 and is connected to the crushing mechanism 3. The conveyor frame 4 is fixedly installed at the upper end of the base frame 1, and the conveying mechanism 5 is installed on the conveyor frame 4. A collection bin 9 is fixedly installed on the upper front side of the base frame 1. A stirring mechanism 8 is installed on the upper end of the collection bin 9 and is connected to the collection bin 9. A batching bin 6 is installed on the stirring mechanism 8 and is connected to the batching bin 6. One end of the conveying mechanism 5 is located below the crushing mechanism 3, and the other end of the conveying mechanism 5 is located above the batching bin 6. A curing slurry tank 7 is set in the middle of the base frame 1. The curing slurry tank 7 can stir the curing agent slurry itself, and the output port of the curing slurry tank 7 is connected to the stirring mechanism 8 through a grouting hose.

[0036] See Figure 3 and Figure 8 The conveying mechanism 5 includes a conveying shaft 51, a conveyor belt 52, a conveying motor 53, and a guide shaft 54. The conveying shaft 51 is symmetrically installed at both ends of the conveying frame 4 through bearings. The conveyor belt 52 is sleeved between the conveying shafts 51. Two sets of guide shafts 54 are symmetrically installed at both ends of the conveying frame 4. The two guide shafts 54 in the same set are located on the inner and outer sides of the conveyor belt 52, respectively. The length of the guide shaft 54 ​​located on the outer side of the conveyor belt 52 is less than the length of the guide shaft 54 ​​located on the inner side of the conveyor belt 52.

[0037] In practice, the prepared curing agent formula is first filled into the curing slurry tank 7 by the staff, and the slurry is continuously stirred in the curing slurry tank 7 to prevent the curing agent slurry from settling and solidifying. Then, the conveyor motor 53 is started to run, which drives the conveyor shaft 51 to rotate, and the conveyor shaft 51 drives the conveyor belt 52 to rotate. The lifting and limiting effect of the conveyor frame 4 and the guide shaft 54 ​​on the conveyor belt 52 can keep the conveyor belt 52 in a smooth and continuous rotation state at the horizontal, inclined and bent lifting parts. Then, the entire truckload of slag is dumped into the unloading bin 2 by the existing slag truck. After being dumped, the slag gradually flows downward and accumulates under its own gravity and the guiding effect of the side wall of the unloading bin 2, and then enters the crushing mechanism 3.

[0038] See Figure 2 , Figure 3 and Figure 8 The crushing mechanism 3 includes a crushing chamber 31, a crushing roller 32, crushing discs 33, a crushing gear 34, a first synchronous pulley 35, and a first synchronous belt 36. The crushing chamber 31 is fixedly installed at the lower end of the unloading chamber 2 and is connected to the crushing chamber 31. Scraping teeth 311 are evenly arranged on the front and rear side walls at the lower end of the crushing chamber 31, and the scraping teeth 311 are located above the damping strip 521. The crushing roller 32 is symmetrically installed in the crushing chamber 31 through bearings. The crushing discs 33 are evenly installed on the crushing roller 32 through key connection. The crushing gear 34 is installed at one end of the crushing roller 32 through key connection, and two adjacent crushing gears 34 mesh with each other for transmission. A first synchronous pulley 35 is symmetrically installed at one end of one crushing roller 32 and one end of one conveying shaft 51 through key connection, and the synchronous pulley on the crushing roller 32 and the synchronous pulley on the conveying shaft 51 are connected by a first synchronous belt 36 for transmission.

[0039] See Figure 3 , Figure 4 and Figure 9 Damping strips 521 are evenly arranged on the conveyor belt 52. A guide plate 41 is fixedly installed on the upper end of the conveyor frame 4. The guide plate 41 is located between the conveyor belt 52 and the batching bin 6. The guide plate 41 facing the batching bin 6 has a downward inclined surface. A scraper 411 is provided on the guide plate 41 facing the conveyor belt 52, and the blade of the scraper 411 abuts against the outer side wall of the conveyor belt 52.

[0040] In specific operation, while the conveyor motor 53 drives the conveyor shaft 51 to rotate, the transmission connection between the first synchronous pulley 35 and the first synchronous belt 36 causes one of the crushing rollers 32 to rotate synchronously. Further, through the meshing transmission between the crushing gears 34, the other symmetrically installed crushing roller 32 rotates synchronously in the opposite direction. This opposing rotation of the crushing rollers 32 causes the crushing discs 33 to rotate synchronously in opposite directions, further crushing the slag accumulated at the transition between the crushing chamber 31 and the unloading chamber 2. Through the staggered meshing of the crushing discs 33, the crushed slag, after being compressed, falls downwards in long strips onto the pre-running conveyor belt 52. Under the combined compression of the crushing discs 33 and the crushing rollers 32, the density of the slag per unit volume increases, and its weight also increases accordingly. During the subsequent lifting and transportation process of the conveyor belt 52, the slag is further crushed. The damping strip 521 on the conveyor belt 52 can further support and separate the slag. The friction caused by the weight of the slag and the separating effect of the damping strip 521 can make the slag adhere tightly to the side wall of the conveyor belt 52, reducing the probability of slag spillage and falling due to the flexible vibration of the conveyor belt 52 itself, and also reducing the generation of dust. When the slag reaches the end of the conveyor belt 52 after transportation, it begins to gradually detach from the conveyor belt 52 under the traction of its own weight, and slides down into the batching bin 6 for secondary accumulation under the guidance of the guide plate 41. The scraper 411 set on the upper end of the guide plate 41 can scrape and clean the slag that remains adhering to the conveyor belt 52. When the scraper 411 slides over the damping strip 521, the vibration caused by the damping strip 521 can accelerate the falling rate of the mud strips accumulated on the guide plate 41, avoiding the backflow of slag and pollution of the surrounding environment of the production line.

[0041] See Figure 3 , Figure 5 , Figure 10 and Figure 11 The lower end of the batching bin 6 is provided with a discharge port that communicates with the mixing bin 81. A discharge valve 61 is installed at the discharge port by means of sliding fit. The discharge valve 61 is sealed to the discharge port. A discharge cylinder 62 is fixedly installed on the side wall of the batching bin 6, and the output shaft of the discharge cylinder 62 is connected to the discharge valve 61 in a transmission manner.

[0042] In specific operation, after the slag in the batching bin 6 has accumulated to a suitable volume, the discharge cylinder 62 is activated. The discharge cylinder 62 pulls the discharge valve 61 to move at the discharge port position, releasing the sealing effect of the discharge valve 61 on the discharge port. Then, under the traction of the slag's own weight, it falls further downward and reaches the mixing mechanism 8.

[0043] See Figure 3 and Figure 10An air compressor 11 is fixedly installed at the middle of the upper end of the base frame 1, and the output port of the air compressor 11 is connected to the curing slurry tank 7 through a hose. A grouting pump 12 is fixedly installed at the middle of the upper end of the base frame 1, and the grouting pump 12 is connected to the grouting hose at the output port of the curing slurry tank 7.

[0044] See Figure 3 , Figure 5 , Figure 6 , Figure 11 and Figure 13 The mixing mechanism 8 includes a mixing chamber 81, a mixing shaft 82, mixing blades 83, a mixing motor 84, a second synchronous pulley 85, a second synchronous belt 86, a discharge chute 87, a grouting pipe 88, and a grouting nozzle 89. The mixing chamber 81 is fixedly installed at the upper end of the collection silo 9, and the upper end of the mixing chamber 81 is connected to the batching silo 6. The mixing shaft 82 is symmetrically installed at the lower end of the mixing chamber 81 through bearings. The mixing blades 83 are fixedly installed on the mixing shaft 82. The mixing blades 83 are helical blades, and only the two ends of the helical blades are connected to the mixing shaft. Furthermore, the spiral blades located on both sides of the waist-shaped groove rotate in opposite directions. A second synchronous pulley 85 is installed at one end of the stirring shaft 82 by a key connection, and the adjacent second synchronous pulleys 85 are connected by a second synchronous belt 86. A stirring motor 84 is fixedly installed on the side wall of the stirring chamber 81 by a motor base. The output shaft of the stirring motor 84 is connected to one of the stirring shafts 82. A grouting pipe 88 is installed in the middle of the stirring chamber 81. One end of the grouting pipe 88 is connected to a grouting hose, and grouting nozzles 89 are evenly arranged at the lower end of the grouting pipe 88.

[0045] In practice, as the excavated soil falls from the batching bin 6, the mixing motor 84 is started. The motor 84 drives one of the mixing shafts 82 to rotate, which in turn drives the other mixing shaft 82 to rotate synchronously via the transmission connection between the second synchronous pulley 85 and the second synchronous belt 86. Since the mixing blades 83 on the two mixing shafts 82 rotate in opposite directions, as the excavated soil accumulates at the bottom of the mixing bin 81, the opposing rotation of the two mixing blades 83 mixes the excavated soil while simultaneously creating opposite flow effects on both sides of the waist-shaped trough. The excavated soil flowing on one side gradually accumulates after being resisted by both ends of the mixing bin 81. Once a suitable accumulation volume is reached, it is again pulled and pushed by the mixing blades 83 on the other side. This process repeats, and under the continuous rotation of the mixing blades 83, the mixing bin 81... The slag on the inner side exhibits a continuous loop flow while being continuously stirred. Since the stirring blades 83 are only connected to the stirring shaft 82 at both ends, and there is a gap between the middle section of the stirring blades 83 and the stirring shaft 82, the slag flow velocity in the area directly pushed by the stirring blades 83 is faster than that in the hollow area not pushed by the stirring blades 83 during the continuous rotation of the stirring blades 83. By making the slag on the same plane have different flow velocities, the slag can be made to tumble in the vertical direction while flowing horizontally, thus improving the stirring effect of the slag. During the slag stirring process, the solidified slurry in the solidified slurry tank 7 is pumped to the grouting pipe 88 through the coordinated work of the air compressor 11 and the grouting pump 12. Then, the solidified slurry is evenly sprayed into the flowing slag through the grouting nozzles 89 set with multiple positions, forming fluidized concrete reinforced soil.

[0046] See Figure 5 and Figure 13 The lower end of the mixing chamber 81 has a waist-shaped structure, and the bottom of the waist-shaped structure protrudes upward. Spring rods 811 are evenly installed at the lower end of the mixing chamber 81. The spring rods 811 are located between the mixing blades 83 and correspond one-to-one with the grouting nozzles 89. A conical ball 812 with inclined surfaces at both the upper and lower ends is fixedly installed at the movable end of the spring rod 811.

[0047] During the actual operation, when the curing agent slurry is sprayed by the grouting nozzle 89, the curing slurry further impacts the conical ball 812 after spraying. Under the continuous impact of the curing slurry, the conical ball 812 and the movable end of the adjacent spring rod 811 begin to reciprocate. Since the upper and lower ends of the conical ball 812 are inclined surfaces, the curing slurry can be evenly dispersed in all directions through its own vibration and its inclined surface, further improving the contact and mixing effect between the curing slurry and the slag.

[0048] See Figure 6 , Figure 11 and Figure 12 A discharge shaft 871 is installed in the discharge trough 87 by means of rotational engagement. A discharge port 872 that matches the discharge trough 87 is opened in the middle of the discharge shaft 871. A discharge pointer 873 is installed at one end of the discharge shaft 871 by means of key connection. One end of the discharge pointer 873 is connected to the side wall of the mixing chamber 81 by means of discharge spring 874. A discharge cylinder 813 is fixedly installed at the upper end of the side wall of the mixing chamber 81. A receiving slide cylinder 814 is fixedly installed at the bottom of the side wall of the mixing chamber 81. An extrusion rod 815 is installed at the upper end of the receiving slide cylinder 814 by means of sliding engagement. The upper end of the extrusion rod 815 has a cross-shaped structure. The extrusion rod 815 is located between the symmetrically arranged discharge pointers 873 and the upper end of the extrusion rod 815 is connected to the discharge cylinder 813 by transmission.

[0049] In specific operation, after the slag and solidifying agent slurry in the mixing chamber 81 are mixed, the discharge cylinder 813 is activated. The discharge cylinder 813 pushes the extrusion rod 815 to retract and move towards the receiving slide 814. During the downward movement of the extrusion rod 815, its cross-shaped edge abuts against one end of the discharge pointer 873, and in the subsequent movement, it pushes the discharge pointer 873 to rotate. While the discharge spring 874 is compressed, the discharge shaft 871 rotates synchronously. After the discharge shaft 871 rotates through the preset angle, the discharge port 872 and the discharge trough 87 are connected to each other. Then, the fluid concrete reinforcement soil accumulated in the mixing chamber 81 gradually flows through the discharge trough 87 and the discharge port 872 under its own weight, and reaches the collection hopper 9 below for collection and storage.

[0050] See Figure 1 and Figure 3 The bottom of the collection silo 9 is provided with a loading valve 91, which is connected and cooperates with the existing transport pump truck. The bottom side of the collection silo 9 is provided with a pipe interface 92, which is connected to the existing silo through the existing pipeline.

[0051] In specific operations, once the fluidized concrete reinforcement soil collected in the collection bin 9 reaches a suitable volume, the existing pump truck is moved to the area below the loading valve 91 to load the fluidized concrete reinforcement soil. After all loading operations for the day are completed, the excess fluidized concrete reinforcement soil produced that day is transported through the existing pipeline to the existing curing bin for curing storage via the pipeline interface 92. The existing curing bin has doors on both sides, and the excavator can excavate the soil from the curing bin after the slag has been cured. At this point, the cured soil has been sanded and can be used directly as roadbed filling material, or it can be used by secondary mixing of curing agent.

[0052] During work:

[0053] Step 1: First, the prepared curing agent formula is uniformly filled into the curing slurry tank 7 by the staff, and the curing slurry tank 7 is continuously stirred to prevent the curing agent slurry from settling and solidifying. Then, the conveyor motor 53 is started to run, which drives the conveyor shaft 51 to rotate, and the conveyor shaft 51 drives the conveyor belt 52 to rotate. The lifting and limiting effect of the conveyor frame 4 and the guide shaft 54 ​​on the conveyor belt 52 can keep the conveyor belt 52 in a smooth and continuous rotation state at the horizontal, inclined and bent lifting parts. Then, the entire truckload of slag is dumped into the unloading bin 2 by the existing slag truck. After being dumped, the slag gradually flows downward and accumulates under its own gravity and the guiding effect of the side wall of the unloading bin 2, and then enters the crushing mechanism 3.

[0054] Step 2: While the conveyor motor 53 drives the conveyor shaft 51 to rotate, the transmission connection between the first synchronous pulley 35 and the first synchronous belt 36 causes one of the crushing rollers 32 to rotate synchronously. Further, the meshing transmission between the crushing gears 34 causes the other symmetrically installed crushing roller 32 to rotate synchronously in the opposite direction. This opposing rotation of the crushing rollers 32 causes the crushing discs 33 to rotate synchronously in opposite directions, further crushing the slag accumulated at the transition between the crushing chamber 31 and the unloading chamber 2. Furthermore, the staggered meshing between the crushing discs 33 further crushes the slag. After being squeezed, the soil falls downwards in a long strip onto the pre-running conveyor belt 52. Under the combined squeezing action of the crushing discs 33 and the crushing rollers 32, the density of the slag per unit volume increases, and its weight also increases accordingly. During the subsequent lifting and transportation process of the conveyor belt 52, the damping strips 521 set on the conveyor belt 52 can further support and separate the slag. Through the friction caused by the weight of the slag and the separating effect of the damping strips 521, the slag can be tightly attached to the side wall of the conveyor belt 52, reducing the probability of the slag spilling and falling due to the flexible vibration of the conveyor belt 52 itself, and also reducing the generation of dust.

[0055] Step 3: After the slag reaches the end of the conveyor belt 52, it begins to gradually detach from the conveyor belt 52 under its own weight and slides down into the batching bin 6 for secondary accumulation under the guidance of the guide plate 41. The scraper 411 set on the upper end of the guide plate 41 can scrape and clean the slag that is still attached to the conveyor belt 52. When the scraper 411 slides over the damping strip 521, the vibration caused by the damping strip 521 can accelerate the falling rate of the mud strips accumulated on the guide plate 41, thus avoiding the backflow of slag and causing pollution to the environment around the production line.

[0056] Step 4: After the slag in the batching bin 6 has accumulated to a suitable volume, the discharge cylinder 62 is started to work. The discharge cylinder 62 pulls the discharge valve 61 to move at the discharge port position, releasing the sealing effect of the discharge valve 61 on the discharge port. Then, under the traction of the slag's own weight, it falls further downward and reaches the mixing mechanism 8.

[0057] Step 5: As the excavated soil falls downwards from the batching bin 6, the mixing motor 84 is started. The mixing motor 84 drives one of the mixing shafts 82 to rotate, which in turn drives the other mixing shaft 82 to rotate synchronously through the transmission connection between the second synchronous pulley 85 and the second synchronous belt 86. Since the mixing blades 83 on the two mixing shafts 82 rotate in opposite directions, as the excavated soil accumulates at the bottom of the mixing bin 81, the opposing rotation of the two mixing blades 83 can simultaneously mix the excavated soil and create a flow effect in opposite directions on both sides of the waist-shaped trough. The excavated soil flowing on one side begins to gradually accumulate after being resisted by the two ends of the mixing bin 81. When a suitable accumulation volume is reached, it is again pulled and pushed by the mixing blades 83 on the other side. This process is repeated. Under the continuous rotation of the mixing blades 83, the mixing bin 81... The slag on the inner side exhibits a continuous loop flow state while being continuously stirred. Since the stirring blades 83 are only connected to the stirring shaft 82 at both ends, and there is a gap between the middle section of the stirring blades 83 and the stirring shaft 82, the slag flow velocity in the area directly pushed by the stirring blades 83 is faster than that in the hollow area not pushed by the stirring blades 83 during the continuous rotation of the stirring blades 83. By making the slag on the same plane have different flow velocities, the slag can be made to tumble in the vertical direction while flowing horizontally, thereby improving the stirring effect of the slag. During the slag stirring process, the solidified slurry in the solidified slurry tank 7 is pumped to the grouting pipe 88 through the coordinated work of the air compressor 11 and the grouting pump 12. Then, the solidified slurry is evenly sprayed into the flowing slag through the grouting nozzles 89 with multiple stations, forming a fluidized concrete reinforced soil.

[0058] Step 6: During the process of spraying the curing agent slurry from the grouting nozzle 89, the curing slurry further impacts the conical ball 812 after spraying. Under the continuous impact of the curing slurry, the conical ball 812 and the movable end of the adjacent spring rod 811 begin to reciprocate. Since the upper and lower ends of the conical ball 812 are inclined surfaces, the curing slurry can be evenly dispersed in all directions through its own vibration and its inclined surface, further improving the contact and mixing effect between the curing slurry and the slag.

[0059] Step 7: After the slag and solidifying agent slurry in the mixing chamber 81 are mixed, the discharge cylinder 813 is started. The discharge cylinder 813 pushes the extrusion rod 815 to retract and move towards the receiving slide 814. During the downward movement of the extrusion rod 815, its cross-shaped edge abuts against one end of the discharge pointer 873 and pushes the discharge pointer 873 to rotate in the subsequent movement. While the discharge spring 874 is compressed, the discharge shaft 871 rotates synchronously. After the discharge shaft 871 rotates through the preset angle, the discharge port 872 and the discharge trough 87 are connected to each other. Then, the fluid concrete reinforcement soil accumulated in the mixing chamber 81 gradually flows through the discharge trough 87 and the discharge port 872 under its own weight and reaches the collection hopper 9 below for collection and storage.

[0060] Step 8: After the fluidized concrete reinforcement soil collected in the collection bin 9 reaches a suitable volume, move the existing pump truck to the loading valve 91 to load the fluidized concrete reinforcement soil. After all the loading operations for the day are completed, transport the excess fluidized concrete reinforcement soil produced that day through the pipeline interface 92 to the existing curing bin for curing storage. The existing curing bin has doors on both sides. After the slag has been cured and solidified, the excavator can dig out the soil from the curing bin. At this time, the cured soil has been sanded and can be used directly as roadbed filling material, or it can be used by secondary mixing of curing agent.
