[0002] Fluidized solidified soil is a filling material with good fluidity, made primarily from soil and a solidifying agent, mixed with water until homogeneous. It is commonly used in engineering projects such as foundation pit backfilling and foundation treatment. Currently, in the preparation of fluidized solidified soil, industrial solid waste and construction waste are often added to the soil as raw materials to reuse these wastes.

This device includes a conveying component, a crushing component, a screening component, a mixer, an auxiliary material component, a pumping component, an additive component, and a control system. It can realize the conveying, crushing, and screening of the main material of slag and soil, quantitatively control the weight ratio of the main material, auxiliary materials, water, and additives, mix and stir them, and then pump fine-grained fluidized solidified soil and coarse-grained fluidized solidified soil to the construction site respectively. This solution achieves automatic material proportioning and metering, and integrated equipment control, making it widely applicable to the preparation of various formulations of fluidized solidified soil. It boasts advantages such as high integration and ease of operation. Patent publication number CN120206638A, relating to the field of construction equipment technology, discloses a fluidized solidified soil preparation device, comprising: a static mixing component, a slurry treatment and conveying component, a curing agent storage and mixing component, and a pumping system. The slurry treatment and conveying component is used for slurry storage and conveying, and the curing agent storage and mixing component is used for curing agent storage and conveying. By connecting the slurry treatment and conveying component and the curing agent storage and mixing component to the first and second inlets of the mixing cylinder, respectively, the slurry and curing agent are conveyed to the mixing chamber for mixing. The pumping system is connected to the first outlet of the mixing cylinder to transport the mixed fluidized solidified soil to the construction location, thereby achieving efficient construction operations. This fluidized solidified soil preparation device achieves integrated design to improve construction convenience. The static mixing component enables efficient mixing of slurry and curing agent, thus ensuring mixing quality and reducing construction costs.

[0004] Although the above-mentioned patents can solve the problems of automatic metering and poor mixing, the following shortcomings still exist: existing preparation equipment is mostly a split-type simple mixing equipment, without a systematic and integrated supporting structure. Each process, such as soil screening, moisture content adjustment, slurry making, mixing, metering and conveying, operates independently. The equipment has low integration, large footprint, cumbersome on-site transportation, and low construction efficiency. Summary of the Invention

[0015] Preferably, the method of using the above-mentioned fluidized solidified soil preparation equipment includes the following steps: S1, Raw material pretreatment and conveying: Engineering waste soil or pile foundation mud is put into the belt conveyor, and the belt conveyor is driven by the drive motor to lift and convey the raw material to the feed hopper on the second layer frame; S2, Vibrating Screening and Grading: The raw material in the feed hopper falls into the vibrating screening mechanism. The drive motor drives the crank to rotate through the second transmission mechanism, causing the vibrating plate to vibrate. The screened fine material falls directly into the premixing bin on the first layer frame through the fine material discharge port, and the screened coarse material enters the primary crushing and mixing bin through the coarse material discharge port. S3, Primary Crushing and Mixing: The material in the primary crushing and mixing chamber enters the primary crushing and mixing chamber after passing through the vibrating screening mechanism. The drive motor drives the primary shaft to rotate through the first bevel gear set, the third main sprocket and the third auxiliary sprocket. The primary shaft drives the crushing and mixing blades to crush and mix the material, forming small particles. S4, Moisture content detection and proportion control: The online moisture content detection sensor in the premixing bin detects the moisture content of the mixed soil in real time and transmits the detection data to the central intelligent control module. The central intelligent control module automatically calculates the material proportion parameters according to the real-time moisture content, design construction strength and fluidity requirements, and controls the metering equipment to quantitatively add raw materials to the secondary homogenizing mixing bin and the premixing bin according to the set proportion. S5, Secondary homogenization mixing: After preliminary mixing and batching in the premixing chamber, the material enters the secondary homogenization mixing chamber through the discharge port of the premixing chamber. The drive motor drives the secondary shaft to rotate through the fourth transmission mechanism. The secondary shaft drives the secondary mixing rod to homogenize and mix the material, forming a uniform and stable fluid slurry. S6, Finished Product Discharge and Conveying: The mixed fluidized solidified soil enters the discharge screw conveyor through the discharge port of the secondary homogenizing mixing chamber, and is then conveyed to the high-pressure output pump, which pumps it to the construction working face to complete the preparation of the fluidized solidified soil.

[0016] The beneficial effects are: 1. By setting up a double-layer frame structure, the belt conveyor, secondary homogenizing mixing chamber, premixing chamber, discharge screw conveyor and high-pressure output pump are arranged in the first layer frame, and the feed hopper, vibrating screen mechanism and primary crushing and mixing chamber are arranged in the second layer frame, forming a three-dimensional stacked compact layout. After the raw material is lifted to the second layer by the belt conveyor, it flows down step by step by gravity. There is no need to add multiple horizontal conveying equipment, which greatly reduces the equipment footprint and simplifies the construction site layout.

[0017] 2. The drive motor sequentially links the belt conveyor, vibrating screen, primary crushing and mixing chamber, and secondary homogenizing mixing chamber via the first, second, third, and fourth transmission mechanisms, enabling one motor to centrally drive multiple core working devices. Compared with the traditional multi-motor independent drive scheme, this reduces the number of motors and electrical control circuits, lowers equipment manufacturing costs and operating energy consumption, simplifies the complexity of the control system, and improves the synchronization and reliability of the entire machine operation.

[0018] 3. The raw materials are separated into fine and coarse materials by a vibrating screening mechanism. The fine materials fall directly into the premixing silo, while the coarse materials enter the primary crushing and mixing silo, where they are broken down by the crushing and mixing blades before being discharged into the premixing silo. This achieves graded processing of coarse and fine materials, avoiding energy waste caused by excessive crushing of fine materials. After preliminary mixing and batching in the premixing silo, the materials enter the secondary homogenizing mixing silo, where they are finely homogenized by the secondary mixing rods. The two-stage differentiated mixing structure eliminates mixing dead zones, allowing the curing agent to fully integrate with the soil and moisture, significantly improving the overall uniformity of the solidified soil, and effectively avoiding potential engineering quality problems such as insufficient local strength, cracking, and settlement.

Detailed Implementation

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] Example 1 A fluidized solidified soil preparation equipment includes an installation frame 1, an equipment mechanism mounted on the installation frame 1, a detection mechanism mounted on the equipment mechanism, and a drive motor 12 mounted on the installation frame 1. The installation frame 1 includes a first frame 101 and a second frame 102. The drive motor 12 is mounted on the second frame 102. The arrangement of the first and second frames 101 provides a foundation for the detection mechanism and the equipment mechanism, facilitating their installation. The equipment mechanism includes a belt conveyor 2, a feed hopper 3, a vibrating screen mechanism 4, a primary crushing and mixing chamber 5, a secondary homogenizing and mixing chamber 6, a premixing chamber 7, a discharge screw conveyor 8, and a high-pressure output pump 9. The drive motor 12 is connected to the belt conveyor 2, the vibrating screen mechanism 4, the primary crushing and mixing chamber 5, and the secondary homogenizing and mixing chamber 6. The belt conveyor 2, the secondary homogenizing and mixing chamber 6, the discharge screw conveyor 8, and the high-pressure output pump 9 are all mounted on the first frame 101. The feed hopper 3, the vibrating screen mechanism 4, the primary crushing and mixing chamber 5, and the premixing chamber 7 are all mounted on the first frame 101. On the second-layer frame 102, the discharge end of the belt conveyor 2 corresponds vertically to the feed hopper 3. The fine material discharge port of the vibrating screen mechanism 4 and the discharge port of the primary crushing and mixing chamber 5 correspond vertically to the feed port of the premixing chamber 7. The coarse material discharge port of the vibrating screen mechanism 4 corresponds to the feed port of the primary crushing and mixing chamber 5. The discharge port of the premixing chamber 7 corresponds to the feed port of the secondary homogenizing mixing chamber 6. The discharge port of the secondary homogenizing mixing chamber 6 corresponds to the feed port of the discharge screw conveyor 8. The discharge port of the discharge screw conveyor 8 corresponds to the high-pressure output pump 9. The feed inlets are interconnected to ensure that the fluidized solidified soil can be prepared and discharged. By starting the drive motor 12, the drive motor 12 can drive the belt conveyor 2, the vibrating screen mechanism 4, the primary crushing and mixing chamber 5, and the secondary homogenizing and mixing chamber 6 to operate. This enables one motor to centrally drive multiple core working devices. Compared with the traditional multi-motor independent drive scheme, this reduces the number of motors and electrical control circuits, lowers the equipment manufacturing cost and operating energy consumption, simplifies the complexity of the control system, and improves the synchronization and reliability of the whole machine operation.

[0022] In this embodiment, a stirring assembly (not shown in the figure) is also provided in the premixing chamber 7. A motor (not shown in the figure) is fixed on the top of the premixing chamber 7. The motor is fixedly connected to the stirring assembly. The structure and principle of the stirring assembly are existing technologies and will not be described in detail here, so that the additives can be initially mixed in the premixing chamber 7 after being added.

[0023] like Figure 1 and Figure 2As shown, the belt conveyor 2 includes two pulleys 201, a transmission belt 202, and a fixed frame 203. The fixed frame 203 is installed between the first frame 101 and the second frame 102. The two pulleys 201 rotate on the fixed frame 203. The transmission belt 202 is wound around the two pulleys 201. One of the pulleys 201 is connected to the drive motor 12 through the first transmission mechanism 13, so that after the drive motor 12 starts, it can drive the pulley 201 to rotate, thereby realizing the material conveying by the transmission belt 202.

[0024] Specifically, the first transmission mechanism 13 includes a first main sprocket 1301, a first auxiliary sprocket 1302, and a first chain 1303. The first main sprocket 1301 is fixed on the output shaft of the drive motor 12, and the first auxiliary sprocket 1302 is synchronously fixedly connected to one of the pulleys 201. When the output shaft of the drive motor 12 rotates, it can drive the first main sprocket 1301 to rotate. Since the first chain 1303 is wound around the first main sprocket 1301 and the first auxiliary sprocket 1302, it can drive the first auxiliary sprocket 1302 to rotate. Then, the first auxiliary sprocket 1302 drives one of the pulleys 201 to rotate. A transmission belt 202 is wound between the two pulleys 201. Therefore, when the pulley 201 rotates, it can drive the transmission belt 202 to operate, thereby realizing the conveying of materials.

[0025] like Figure 1 , Figure 2 and Figure 6 As shown, the vibrating screening mechanism 4 includes a crank 401, several swing rods 402, and a vibrating plate 403. The lower ends of the swing rods 402 are rotatably connected to the second frame 102, and the upper ends of the swing rods 402 are rotatably connected to the vibrating plate 403. One end of the crank 401 is rotatably connected to the second frame 102 via a base, and the other end of the crank 401 is rotatably connected to the vibrating plate 403. The end of the crank 401 near the base is connected to one of the pulleys 201 via a second transmission mechanism 14. After the drive motor 12 is started, it can drive one of the pulleys 201 to rotate, and drive the crank 401 to rotate via the second transmission mechanism 14, thereby realizing the vibration of the vibrating plate 403. This causes the fine material to fall from the vibrating plate 403 into the premixing chamber 7, while the coarse material vibrates from the vibrating plate 403 into the primary crushing and mixing chamber 5.

[0026] Specifically, the second transmission mechanism 14 includes a second main sprocket 1401, a second auxiliary sprocket 1402, a second chain 1403, and a second bevel gear set. In this embodiment, the second bevel gear set includes a second main bevel gear and a second auxiliary bevel gear. The second main bevel gear is fixed on the connecting rod, and the second auxiliary bevel gear is coaxially and fixedly connected to the crank 401. The second main bevel gear and the second auxiliary bevel gear mesh with each other, so that the rotation of the connecting rod can drive the crank 401 to rotate. The second main sprocket 1401 is coaxially and fixedly connected to the first auxiliary sprocket 1402. The premixing chamber 7 is rotatably connected to the connecting rod via a base, and the second auxiliary sprocket 1402... The connecting rod is fixedly connected to the connecting rod, which is connected to the crank rod 401 via the second bevel gear set. When the first auxiliary sprocket 1302 rotates, it can drive the second main sprocket 1401 to rotate. Since the second chain 1403 is wound around the second main sprocket 1401 and the second auxiliary sprocket 1402, it can drive the second auxiliary sprocket 1402 to rotate, which in turn drives the connecting rod to rotate. The rotation of the connecting rod can drive the crank rod 401 to rotate. The crank rod 401 drives the vibrating plate 403 to swing, so that the fine material falls from the vibrating plate 403 into the premixing chamber 7, while the coarse material vibrates from the vibrating plate 403 into the primary crushing and mixing chamber 5.

[0027] like Figures 1-5 and Figure 7 As shown, the primary crushing and mixing chamber 5 includes a primary rotating shaft 501, crushing and mixing blades 502, and a primary mixing drum 503. The primary mixing drum 503 is installed on the second layer frame 102. The primary rotating shaft 501 rotates inside the primary mixing drum 503. There are several crushing and mixing blades 502, which are fixed on the primary rotating shaft 501. The upper end of the primary rotating shaft 501 passes through the primary mixing drum 503 and is connected to the drive motor 12 through the third transmission mechanism 15. After the drive motor 12 starts, it can drive the primary rotating shaft 501 to rotate, which in turn drives the crushing and mixing blades 502 to rotate, thereby crushing and mixing the material in the primary mixing drum 503. The top of the primary mixing drum 503 is provided with a primary feed inlet for the coarse material on the vibrating plate 403 to fall into the primary crushing and mixing chamber 5.

[0028] Specifically, the third transmission mechanism 15 includes a first bevel gear set 1501, a third main sprocket 1502, a third auxiliary sprocket 1503, and a third chain 1504. In this embodiment, the first bevel gear set 1501 includes a first main bevel gear and a first auxiliary bevel gear. The first main bevel gear is fixed on the output shaft of the drive motor 12, and the first auxiliary bevel gear is fixed on a short rod. The first main bevel gear and the first auxiliary bevel gear mesh with each other. A short rod is rotatably connected to the second frame 102 via a mounting base. The drive motor 12 transmits power to the short rod through the first bevel gear set 1501. The connection is such that the third main sprocket 1502 is fixed on the short rod, and the third auxiliary sprocket 1503 is fixed on the primary rotating shaft 501. When the drive motor 12 starts, it can also drive the first bevel gear set 1501 to rotate, and then drive the third main sprocket 1502 to rotate. Since the third chain 1504 is wound around the third main sprocket 1502 and the third auxiliary sprocket 1503, it can drive the third auxiliary sprocket 1503 to rotate. The third auxiliary sprocket 1503 can drive the primary rotating shaft 501 to rotate, so that the primary rotating shaft 501 drives the crushing and mixing blades 502 to rotate.

[0029] like Figures 1-5 and Figure 7 As shown, the secondary homogenizing mixing chamber 6 includes a secondary rotating shaft 601, secondary stirring rods 602, and a secondary mixing tank 603. The secondary mixing tank 603 is fixedly installed on the first layer frame 101. The secondary rotating shaft 601 rotates inside the secondary mixing tank 603. There are several secondary stirring rods 602, which are fixedly arranged in a circumferential array on the secondary rotating shaft 601. The upper end of the secondary rotating shaft 601 extends out of the secondary mixing tank 603 and is connected to the primary rotating shaft 501 through the fourth transmission mechanism 16. This allows the drive motor 12 to start and drive the primary rotating shaft 501 to rotate. When the primary rotating shaft 501 rotates, it drives the secondary rotating shaft 601 to rotate, thereby enabling the secondary stirring rods 602 to mix and stir the materials in the secondary mixing tank 603. The secondary mixing tank 603 has a secondary feed port for the premixed material in the premixing chamber 7 to fall into.

[0030] Specifically, the fourth transmission mechanism 16 includes a vertical rod 1601, a first-stage fourth sprocket 1602, a second-stage fourth sprocket 1603, a third-stage fourth sprocket 1604, and a fourth-stage fourth sprocket 1605. The vertical rod 1601 rotates on the first-layer frame 101. The second-stage fourth sprocket 1603 and the third-stage fourth sprocket 1604 are fixed to the vertical rod 1601. The first-stage fourth sprocket 1602 is fixed to the short rod. The fourth-stage fourth sprocket 1605 is fixed to the second-stage rotating shaft 601. The first-stage fourth sprocket 1602 is fixed to the primary rotating shaft 501 to make the short rod... The rotation can drive the first-stage fourth sprocket 1602 to rotate. Since the first-stage fourth sprocket 1602 and the second-stage fourth sprocket 1603 are connected by the fourth main chain, the second-stage fourth sprocket 1603 can drive the vertical rod 1601 to rotate. Since the third-stage fourth sprocket 1604 is fixed on the vertical rod 1601 and the third-stage fourth sprocket 1604 and the fourth-stage fourth sprocket 1605 are connected by the fourth auxiliary chain, the third-stage fourth sprocket 1605 can drive the fourth-stage fourth sprocket 1605 to rotate. The fourth-stage fourth sprocket 1605 then drives the second-stage rotating shaft 601 to rotate.

[0031] like Figures 8-10 As shown, the detection mechanism includes an online moisture content detection sensor 10 and a metering device. The online moisture content detection sensor 10 is installed in the premixing chamber 7, and the metering device is installed on the second-layer frame 102 and located between the equipment mechanisms to measure the material.

[0032] Specifically, the metering equipment includes a soil metering component 1101, a curing agent storage metering component 1102, a water metering component 1103, and an admixture micro-metering component 1104. In this embodiment, the soil metering component 1101, the curing agent storage metering component 1102, the water metering component 1103, and the admixture micro-metering component 1104 are all existing technologies and will not be described in detail here. The soil metering component 1101 is installed on the feed hopper 3 and is located between the feed hopper 3 and the vibrating screening mechanism 4. The soil metering component 1101 is connected to the feed hopper 3. The soil metering component 1101 is mounted on the first-layer frame 101 via a support bracket. Its inlet and outlet are connected to the feed hopper 3 and vibrating screen mechanism 4 via flexible hoses, respectively. The curing agent storage metering component 1102 is mounted on the first-layer frame 101 and located at the inlet of the premixing silo 7. The curing agent storage metering component 1102 is fixed above the premixing silo 7 by steel components. The screw conveyor is connected to the inlet of the premixing silo 7 via a flange pipe. The structure and principle of the screw conveyor are existing technologies and will not be described in detail here. The water metering component 1... 103 is installed on the first layer frame 101 and located at the inlet of the premixing chamber 7. The clean water metering component 1103 includes a water tank, an electromagnetic flow meter, and a metering pump with a level gauge. The water tank is fixed on the outer wall of the premixing chamber 7. The water outlet pipe of the water tank is connected to the feed inlet of the premixing chamber through a metering pipeline. An electromagnetic flow meter and a metering pump are installed on the pipeline to deliver clean water in a metered manner according to the mixing ratio. The additive micro-metering component 1104 is installed on the first layer frame 101 and located at the inlet of the secondary homogenizing mixing chamber 6. The additive micro-metering component 1104 includes an additive storage tank. The system consists of a tank, a micro-screw pump, a pulse damper, a high-precision flow meter, and a solenoid valve (all shown in the figure). The admixture storage tank and the micro-screw pump are fixed to the side of the secondary homogenizing mixing chamber 6 by independent supports. The metered admixture liquid is introduced into the top inlet of the secondary homogenizing mixing chamber 6 through a rigid pipeline or a small-diameter pipeline with a flexible hose connector. The connection between the pipeline and the secondary homogenizing mixing chamber 6 can be made of threaded flange or short flexible joint, which is only used for sealing and thermal expansion and contraction compensation, and does not bear the weight of the pump set and the storage tank. This can prevent the admixture from being adsorbed by soil particles too early and ensure the homogeneity of the slurry.

[0033] Example 2 A method of using a fluidized solidified soil preparation equipment includes the following steps: S1, raw material pretreatment and conveying: engineering waste soil or pile foundation mud is put into belt conveyor 2, and the belt conveyor 2 is driven by drive motor 12 to lift and convey the raw material to the feed hopper 3 on the second layer frame 102; S2, Vibrating screening and grading: The raw material in the feed hopper 3 falls into the vibrating screening mechanism 4. The drive motor 12 drives the crank 401 to rotate through the second transmission mechanism 14, causing the vibrating plate 403 to vibrate. The screened fine material falls directly into the premixing bin 7 on the first layer frame 101 through the fine material discharge port, and the screened coarse material enters the primary crushing and mixing bin 5 through the coarse material discharge port. S3, Primary crushing and mixing: The material in the primary crushing and mixing chamber 5 enters the primary crushing and mixing chamber 5 after passing through the vibrating screen mechanism 4. The drive motor 12 drives the primary rotating shaft 501 to rotate through the first bevel gear set 1501, the third main sprocket 1502 and the third auxiliary sprocket 1503. The primary rotating shaft 501 drives the crushing and mixing blades 502 to crush and mix the material to form small particles. S4, Moisture content detection and proportion control: The online moisture content detection sensor 10 in the premixing bin 7 detects the moisture content of the mixed soil in real time and transmits the detection data to the central intelligent control module. The central intelligent control module automatically calculates the material proportion parameters according to the real-time moisture content, design construction strength and fluidity requirements, and controls the metering equipment to quantitatively add raw materials to the secondary homogenizing mixing bin 6 and the premixing bin 7 according to the set proportion. S5, Secondary homogenization mixing: The material after preliminary mixing and batching in the premixing chamber 7 enters the secondary homogenization mixing chamber 6 through the discharge port of the premixing chamber 7. The drive motor 12 drives the secondary rotating shaft 601 to rotate through the fourth transmission mechanism 16. The secondary rotating shaft 601 drives the secondary stirring rod 602 to homogenize and mix the material to form a uniform and stable fluid slurry. S6, Finished product discharge and conveying: The mixed fluidized solidified soil enters the discharge screw conveyor 8 through the discharge port of the secondary homogenizing mixing chamber 6, and is conveyed to the high-pressure output pump 9 by the discharge screw conveyor 8. The high-pressure output pump 9 pumps the soil to the construction working face to complete the preparation of fluidized solidified soil.

[0034] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is that the drive motor 12 can drive the belt conveyor 2, the vibrating screening mechanism 4, the primary crushing and mixing chamber 5, and the secondary homogenizing and mixing chamber 6, realizing the centralized driving of multiple core working devices by one motor. Compared with the traditional multi-motor independent drive scheme, this reduces the number of motors and electrical control circuits, lowers equipment manufacturing costs and operating energy consumption, simplifies the complexity of the control system, and improves the synchronization and reliability of the overall machine operation. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
