Description

Technical Field

[0001] This utility model relates to the technical field of fluid soil mixing, and in particular to a large-scale fluid soil planetary mixing device. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in construction projects and urban renovation projects, the requirements for the preparation of fluid soil, a new type of environmentally friendly material used for backfilling, are gradually increasing. Mechanical mixing technologies for fluid soil mixing mechanisms mainly include three mainstream forms: horizontal twin-shaft, vertical, and planetary. Horizontal twin-shaft mixers use counter-rotating twin shafts and staggered blades to achieve efficient shear mixing, suitable for large-scale continuous operations. Vertical mixers use a vertical shaft to drive blades to form an up-and-down circulating mixing process; their compact structure makes them suitable for space-constrained applications. Planetary mixers utilize a complex motion trajectory combining revolution and rotation to ensure mixing without dead zones, making them particularly suitable for conditions requiring high uniformity. These mechanical mixing methods all improve mixing efficiency and reduce energy consumption by optimizing blade structure and motion patterns, making them the core technologies for current fluid soil treatment.

[0003] Mechanical mixing technology for fluidized soil faces numerous challenges in practical applications: horizontal twin-shaft mixers suffer from large size, complex maintenance, rapid blade wear, and high energy consumption; vertical mixers are limited by small processing capacity, easy material accumulation, and the tendency for sticky materials to adhere to the shaft; while planetary mixers offer good mixing uniformity, they face challenges such as high cost, high energy consumption, and difficult maintenance. These technologies generally suffer from common problems such as sticky material adhesion, poor soil adaptability, severe wear of key components, and excessive energy consumption, which seriously restrict mixing efficiency and quality, and drive up operating costs. Overcoming these technical bottlenecks requires material innovation, structural optimization, and intelligent upgrades.

[0004] With technological advancements, market demand for equipment capable of mass-producing high-quality fluidized soil is increasing. Existing equipment, when handling large-scale, continuous production, struggles to simultaneously achieve both uniform mixing and precise control of the batching ratio. Furthermore, it is prone to efficiency decline and increased maintenance costs when dealing with different soil types and prolonged operation. Therefore, there is an urgent need for a fluidized soil mixing technology or device that can ensure high-volume mixing capacity while achieving precise control of the batching ratio and maintaining uniform mixing, to meet the industry's growing application requirements.

[0065] Below, in conjunction with Figures 1 to 18 This invention provides a detailed description of a large-scale fluidized soil planetary mixing device.

[0066] This utility model provides a large-scale fluidized soil planetary mixing device, consisting of... Figure 1As shown, the system includes a planetary mixing section 1000 for mixing fluidized soil, a curing agent metering addition section 2000, an earthwork feeding section 3000 for feeding earthwork, a water control section 4000, an auxiliary observation section 5000, and a finished fluidized soil conveying section 6000. The curing agent metering addition section 2000 is welded to the planetary mixing section 1000, the earthwork feeding section 3000 is welded to the planetary mixing section 1000, the water control section 4000 is welded to the planetary mixing section 1000, the auxiliary observation section 5000 consists of a ladder fixed with screws below the observation window 1300 of the planetary mixing section 1000, and the finished fluidized soil conveying section 6000 is welded to the planetary mixing section 1000. The curing agent metering addition section 2000, the earthwork feeding section 3000, and the water control section 4000 surround the outer shell 11 of the planetary mixing section 1000. The upper part of the 00 is fixed, and the fluidized soil finished product conveying part 6000 is fixed to the lower part of the outer shell 1100 of the planetary mixing part 1000. During the operation of the device, the soil feeding part 3000 will send soil into the planetary mixing part 1000, and the curing agent quantitative addition part 2000 and the water control part 4000 will cooperate with the soil feeding part 3000 to input curing agent and water into the planetary mixing part 1000 respectively. The auxiliary observation part 5000 provides a ladder for the staff to observe the mixing situation through the observation window 1300. After the mixing is completed, the fluidized soil finished product conveying part 6000 will transport the fluidized soil out of the planetary mixing part 1000.

[0067] Planetary stirring section 1000, by Figure 2 As shown, the device includes a casing 1100 (serving as a mixing tank, mounted on the ground), a mixing blade 1200, an observation window 1300, a braking mechanism 1400, a planetary transmission mechanism 1500, a starting mechanism 1600, a power motor 1700, and an I-beam 1800 for load-bearing. The mixing blade 1200 is connected to the planetary transmission mechanism 1500 via a pin. The observation window 1300 is connected to the casing 1100 via screws. The braking mechanism 1400 is connected to the casing 1100 via welding. The planetary transmission mechanism 1500 is fitted to the casing 1100 via a sliding groove. The starting mechanism 1600 is connected to the casing 1100 via bolts. The power motor 1700 is connected to the I-beam 1800 via bolts and also to the planetary transmission mechanism 1500 via a pin. The I-beam 1800 is connected to the casing 1100 via welding.

[0068] 1200 stirring blades, made of Figure 7As shown, it includes a stirring shaft 1210 and tungsten carbide blades 1220. The stirring shaft 1210 and tungsten carbide blades 1220 are connected by both bolts and welding, making them very robust. The tungsten carbide blades 1220 are made of high-strength, wear-resistant material, and their inclined design pushes the fluid soil to move up and down, disrupting the laminar flow of the fluid soil and making the mixing more uniform. The observation window 1300 is a transparent solid, allowing workers to easily observe the mixing status inside the tank to determine the unloading time. The braking mechanism 1400 is... Figure 8 , Figure 16 , Figure 17 As shown, the device includes a brake mechanism cylinder 1410, a brake mechanism piston 1420, and a brake mechanism friction plate 1430. The brake mechanism cylinder 1410 is welded to the outer casing 1100. The brake mechanism piston 1420 is inserted into a groove in the brake mechanism cylinder 1410, with the empty space filled with hydraulic oil. The brake mechanism friction plate 1430 is welded to the brake mechanism piston 1420. During operation, hydraulic oil is injected into the brake mechanism cylinder 1410, causing the brake mechanism piston 1420 to be pushed. This causes the brake mechanism friction plate 1430 to engage with the internal gear friction plate 1520 in the planetary transmission mechanism 1500, thus locking the rotation of the gear ring 1510. This state is considered the braking state. To release the braking state, the hydraulic oil in the brake mechanism cylinder 1410 is extracted. The planetary transmission mechanism 1500... Figure 9 , Figure 16 , Figure 17 , Figure 18As shown, the system includes a gear ring 1510, an internal gear friction plate 1520, an external gear ring 1530, planetary gears 1540, a planetary transmission mechanism splash guard 1550, a planetary carrier 1560, and a thrust ball bearing 1570. The gear ring 1510 is mounted on the housing 1100. The internal gear friction plate 1520 is welded onto the gear ring 1510. The external gear ring 1530 is located outside the gear ring 1510. The planetary gears 1540 are connected to the stirring blade 1200 via pins. The planetary transmission mechanism splash guard 1550 is welded onto the housing 1100. At the bottom of the planetary carrier 1560, which is mounted on the housing 1100, a thrust ball bearing 1570 is placed between the planetary gear 1540 and the planetary carrier 1560. During operation, the internal gear friction plate 1520 engages with the brake mechanism friction plate 1430 to lock the rotation of the gear ring 1510. The external gear ring 1530 meshes with the starting gear 1610 during the starting phase to transmit starting power. The planetary transmission mechanism anti-splash plate 1550 prevents debris from splashing during stirring and interfering with the movement of the planetary transmission mechanism. The planetary carrier 1560 is used to support the planetary gears. 1540, the thrust ball bearing 1570 reduces the friction between the planetary gear 1540 and the planetary carrier 1560, reduces internal losses, and improves working efficiency. During device startup, the external gear ring 1530, driven by the rotation of the gear, provides a certain amount of kinetic energy to facilitate the starting of the power motor 1700. In the initial stages of feeding and mixing, due to uneven soil and water distribution, directly rotating the mixing shaft 1210 can easily damage the mixing shaft 1210 and the tungsten carbide blades 1220. Therefore, the gear ring 1510 is not restricted. The planetary carrier 1560, due to the soil... The resistance does not cause rotation. After initial homogenization, the braking mechanism 1400 activates the brake, injecting hydraulic oil into the brake mechanism cylinder 1410. This pushes the brake mechanism piston 1420, causing the brake mechanism friction plate 1430 to engage with the internal gear friction plate 1520 in the planetary transmission mechanism 1500, locking the gear ring 1510. The planetary carrier 1560 then begins to rotate. This segmented mixing method avoids damage to the mixing shaft 1210 and the tungsten carbide blades 1220, while also achieving higher homogenization of the fluidized soil after mixing. The starting mechanism 1600, by… Figure 10 As shown, the device includes a starter motor 1620 for providing starting power and a starter gear 1610 for transmitting starting power. The starter gear 1610 is connected to the starter motor 1620 via a shaft pin and meshes with an external gear ring 1530. The starter motor 1620 is connected to the housing 1100 via bolts. During operation, the starter motor 1620 outputs power, which is transmitted to the planetary transmission mechanism 1500 via the starter gear 1610 to assist in starting the power motor 1700. The starter motor 1620 is a high-power motor that provides power for starting the power motor 1700. The power motor 1700 is a high-power three-phase asynchronous motor with a reducer, which provides sufficient torque for mixing the fluid soil.

[0069] The curing agent is added in a quantitative amount of 2000, from Figure 3 As shown, the device includes a curing agent feeding section 2100 for storing and feeding the curing agent, a curing agent dosage control section 2200 for metering the curing agent, a curing agent metering and adding section housing 2300, a curing agent anti-caking section 2400 for drying the curing agent, and a curing agent feeding section anti-splash door 2500 for preventing the curing agent from being contaminated. The curing agent feeding section 2100 is bolted to the top of the curing agent metering and adding section housing 2300. The curing agent dosage control section 2200 is connected to the inside of the curing agent metering and adding section housing 2300 via bearings. The curing agent anti-caking section 2400 is screwed to the bottom of the curing agent metering and adding section housing 2300. The curing agent feeding section anti-splash door 2500 is screwed to the bottom end of the curing agent metering and adding section housing 2300. The curing agent metering and adding section housing 2300 is fixed to the housing 1100 by welding.

[0070] Curing agent feed section 2100, by Figure 11 As shown, the device includes a curing agent feed funnel 2110 for temporary storage of the curing agent and a curing agent feed butterfly valve 2120 for controlling the opening and closing of the curing agent feed. The curing agent feed funnel 2110 is connected to the curing agent feed butterfly valve 2120 by welding. The curing agent feed butterfly valve 2120 is connected to the curing agent metering and adding housing 2300 by bolts. During operation, the curing agent feed butterfly valve 2120 is opened and closed as needed by the operator. When open, the curing agent is allowed to pass through; when closed, it is not allowed. The curing agent feed funnel 2110 is used to hold the curing agent. A curing agent dosage control section 2200 is also included. Figure 12 , Figure 13As shown, the device includes an electromagnet 2210 (as a magnetic force generating device), a contact spring 2220, an insulating mounting plate 2230, a conductive sheet 2240, a cam 2250, a curing agent hopper 2260 for holding the curing agent, a bearing 2270, and a rotating shaft 2280. The electromagnet 2210 is screwed to the curing agent metering section housing 2300. The insulating mounting plate 2230 is screwed to the curing agent metering section housing 2300. The insulating mounting plate 2230 has upper and lower mounting slots. The contact spring 2220 is bolted to the upper mounting slot of the insulating mounting plate 2230. The contact spring 2220 is a thin, elastic sheet containing an iron ball attracted by the electromagnet 2210. The electrode 2240 is fixed to the lower mounting groove of the insulating mounting plate 2230 by bolts. The rotating shaft 2280 is connected to the housing 2300 of the curing agent metering part via the bearing 2270. The cam 2250 is divided into two fan-shaped areas, left and right. Each fan-shaped area consists of an outer arc-shaped alloy plate and structures on both inner sides. One side of the two fan-shaped areas is symmetrically set as an alloy rod. A rectangular connecting block is provided at the connection between the two fan-shaped areas. The alloy rod and the rectangular connecting block are connected together by welding. The other side of the two fan-shaped areas, symmetrically opposite the alloy rod, is set as a curing agent hopper 2260. The rectangular connecting block has a circular opening in the middle. The rotating shaft 2280 passes through the circular opening and is fixed together with the rectangular connecting block by welding. The outer surface of hopper 2260 is connected to a connecting rod extending from the outside of a rectangular connecting block. One end of the curing agent hopper 2260 near the outside of the fan-shaped area is welded to the end of the arc-shaped alloy plate. The curing agent hoppers 2260 in the two fan-shaped areas are arranged symmetrically in opposite directions. During operation, the electromagnet 2210 controls its magnetic field strength by adjusting the current passing through it. The iron ball in the contact spring 2220 is attracted by the electromagnet 2210, and the end of the contact spring 2220 contacts the end of the arc-shaped alloy plate in the nearest fan-shaped area. When there is enough curing agent in the curing agent hopper 2260, the contact spring 2220 separates from the electromagnet 2210 and bends downwards under the push of the cam 2250, contacting the conductive sheet 2. When the two electrodes 240 come into contact, an electrical signal is generated. The curing agent hopper 2260 is used to receive the curing agent released from the curing agent feed section 2100. The bearing 2270 is used to ensure that the curing agent hopper 2260 and the cam 2250 can rotate together. After the contact spring 2220 separates from the electromagnet 2210, the cam 2250 continues to rotate clockwise until the contact spring 2220 contacts the conductive plate 2240. The cam 2250 reaches a critical point. If any weight of curing agent is added at this time, the contact spring 2220 will separate from the end of the arc-shaped alloy plate it contacts. After that, the curing agent hopper 2260 and the cam 2250 will continue to rotate due to gravity, and the curing agent in the curing agent hopper 2260 will be poured out.Due to inertia, the two curing agent hoppers 2260 and cam 2250 will continue to rotate until the total rotation angle reaches 180 degrees. At this point, the other curing agent hopper 2260, which has never had curing agent added, will be stopped by the contact spring 2220, entering the next cycle. The curing agent anti-caking section 2400 includes a drying sheet 2410 and a mounting plate 2420. The drying sheet 2410 is connected to the mounting plate 2420 by screws, and the mounting plate 2420 is connected to the bottom of the curing agent metering section housing 2300 by screws. During operation, the soda lime in the drying sheet 2410 absorbs moisture, thus ensuring the dryness of the interior of the curing agent metering section 2000. Simultaneously, the bent dry... The drying sheet 2410 increases the time for moisture to pass through, effectively enhancing the drying effect. The drying sheet 2410 can be quickly removed and replaced on the mounting plate 2420. The curing agent inlet anti-splash door structure 2500 includes a curing agent inlet anti-splash door panel 2510 and a curing agent inlet anti-splash door hinge 2520. The curing agent inlet anti-splash door hinge 2520 is connected to the bottom end of the curing agent metering addition section housing 2300 by screws. The curing agent inlet anti-splash door panel 2510 is connected to the curing agent inlet anti-splash door hinge 2520 by screws. During operation, the curing agent inlet anti-splash door hinge 2520 is normally closed. When the curing agent flows through, it will be knocked away. When no curing agent flows through, it will prevent splashes from entering the curing agent metering section 2000, and at the same time, it can extend the service life of the drying sheet 2410. When the curing agent is fed, the butterfly valve 2120 of the curing agent feeding section is controlled to open and close by a PLC control system. The PLC control system receives signals from the hinge 3400 and the contact spring 2220 of the earthwork feeding section, and then controls the opening and closing of the butterfly valve 2120 of the curing agent feeding section. When it is open, the curing agent in the funnel 2110 of the curing agent feeding section falls into the curing agent dosage control section 2200 due to gravity. The curing agent dosage control section 2200 is controlled by an electromagnet 2210 in conjunction with the contact spring 2220. The conductive sheet 2240 enables precise metering of the curing agent and sends electrical signals to the PLC control system. The curing agent anti-caking section 2400 absorbs moisture seeping from the planetary mixing section 1000, ensuring the dryness inside the curing agent metering addition section shell 2300, thus ensuring accurate weighing in the curing agent dosage control section 2200. The PLC control system is a general-purpose component, typically consisting of a central processing unit, input modules, output modules, a power supply module, and a communication interface. It primarily receives signals from various devices within the system and sends control signals to them. The curing agent inlet anti-splash door 2500 is normally closed to prevent fluidized soil from splashing into the curing agent metering addition section shell 2300.

The housing 3300 is welded to the housing 1100, the filter screen 3200 is screwed to the housing 3300, the top of the angle iron 3100 is bolted to the housing 3300, and its bottom is set on the ground. The hinge 3400 is screwed to the bottom end of the housing 3300, and the splash guard 3500 is screwed to the hinge 3400. During operation, the earthwork feeding section... The angle iron 3100 of the soil feed section provides support, preventing the soil feed section 3000 from falling and improving its stability. The filter screen 3200 of the soil feed section can filter out some large stones, concrete blocks, and other materials that will wear down the mixing blades 1200, reducing unnecessary equipment wear. The outer shell 3300 of the soil feed section guides the soil to a designated path, allowing it to fall naturally into the planetary mixing section 1000. The hinge 3400 of the soil feed section connects the outer shell 3300 of the soil feed section to the anti-splash door 3500 of the soil feed section. At the same time, a sensor is installed inside to detect its opening and closing status. The anti-splash door 3500 of the soil feed section is normally closed, which can effectively prevent the mixed fluid soil from splashing into the inner shell 3300 of the soil feed section. When soil needs to be added, the soil is placed at the funnel inlet above the outer shell 3300 of the soil feed section.

[0072] Water control section 4000, by Figure 5As shown, the system includes a butterfly valve 4100 for controlling the water supply switch, a water supply pipe 4200 for supplying water, a flow meter 4300 for monitoring flow rate, and an inlet pipe 4400. The water supply pipe 4200 is welded to the housing 1100, the butterfly valve 4100 is bolted to the water supply pipe 4200, the flow meter 4300 is bolted to the water supply pipe 4200, and the inlet pipe 4400 is bolted to the flow meter 4300. During operation, the butterfly valve 4100 in the water control section receives electrical signals from the PLC control system to complete the opening and closing operations. The water supply pipe 4200 in the water control section is used to connect the butterfly valve 4100 in the water control section to the planetary mixing section 1000, which delivers water to the planetary mixing section 1000. The flow meter 4300 in the water control section detects the water flow rate passing through it and transmits the data back to the PLC control system. At the same time, it sends a cut-off signal to the butterfly valve 4100 in the water control section according to the set value. The water inlet pipe 4400 in the water control section connects to the water source and delivers water to the flow meter 4300 in the water control section for metering.

[0073] The 6000-ton fluidized soil finished product conveying section is composed of... Figure 6 As shown, the device includes a butterfly valve 6100 for conveying finished fluid soil, a flange 6200, and a fluid soil output pipe 6300 for conveying fluid soil. The fluid soil output pipe 6300 is connected to the lower part of the outer shell 1100 of the planetary mixing unit 1000 by welding. The butterfly valve 6100 for conveying finished fluid soil is bolted to the fluid soil output pipe 6300. The flange 6200 is part of the butterfly valve 6100 for conveying finished fluid soil. During operation, the butterfly valve 6100 for conveying finished fluid soil is controlled to open and close by a PLC control system, and the flange 6200 is connected to other equipment that needs to supply fluid soil. The fluid soil output pipe 6300 conveys the finished fluid soil to other equipment through the butterfly valve 6100 for conveying finished fluid soil.

[0074] Below, refer to Figures 1 to 18 Based on the above description of structural features, the working principle of the large-scale fluidized soil planetary mixing device of this utility model will be explained in detail, including the following steps:

[0075] S1. Preparation Stage: In this stage, it is necessary to check that all equipment parameters are normal, there are no foreign objects in the planetary mixing section 1000, all devices are operating normally, bolts and screws are tightened, the auxiliary observation section 5000 is undamaged, and there are no foreign objects on the filter screen 3200 of the soil feeding section. After the inspection is completed, ensure that the butterfly valve 4100 of the water control section, the butterfly valve 2120 of the curing agent feeding section, and the butterfly valve 6100 of the fluidized soil finished product conveying section are in the closed state. Connect the water source to the water inlet pipe 4400 of the water control section. Add the approximate amount of curing agent required for this mixing to the funnel 2110 of the curing agent feeding section. The actual amount added should not be less than the amount of curing agent required for this mixing. Connect the equipment for pumping fluidized soil or other equipment that requires fluidized soil to the flange 6200. Release the braking state of the brake mechanism 1400 by extracting the hydraulic oil in the brake mechanism cylinder 1410. The staff climbs the ladder of the auxiliary observation section 5000 to observe the situation inside the window, ready to start mixing and set the corresponding parameters:

[0076] 1. Set the magnetic strength of electromagnet 2210 according to the single soil intake of earthmoving equipment such as excavator, and adjust the current through electromagnet 2210 so that the curing agent required for the single soil intake is just enough to separate electromagnet 2210 from contact spring 2220 by its own weight.

[0077] 2. Based on the single soil intake volume of earthmoving equipment such as excavators, set the flow rate required for the water control section flow meter 4300 to send a cut-off signal each time. This flow rate is proportional to the single soil intake volume. Before mixing, control the start motor 1620 to start, and start the power motor 1700 a few seconds later. After the device stabilizes, turn off the start motor 1620.

[0078] S2. Mixing Stage: After completing step S1, the excavator is started to feed soil into the earthwork feed section 3000. Each time the excavator feeds soil, the splash guard 3500 of the earthwork feed section is opened, activating the hinge 3400. This hinge sends a signal to the PLC control system, which then sends an opening signal to the butterfly valve 4100 in the water control section and the butterfly valve 2120 in the curing agent feed section. This signal switches both valves to the open state. In the curing agent metering addition section 2000, the curing agent is caught by the curing agent hopper 2260, and the mass begins to accumulate. When the accumulated curing agent reaches the preset mass... The magnetic field of electromagnet 2210 is insufficient to attract the iron ball of contact spring 2220 to hinder the rotation of cam 2250. Contact spring 2220 is pushed downwards, and the iron ball of contact spring 2220 interacts with conductive sheet 2240 and sends a signal to PLC control system. PLC control system then sends a closing signal to butterfly valve 2120 of curing agent feed section. This signal causes butterfly valve 2120 of curing agent feed section to switch to open circuit state, and also stops electromagnet 2210 from working. Due to gravity, curing agent hopper 2260 will rotate clockwise, and curing agent will be poured into curing agent metering addition section shell 2300. Due to inertia, cam 2250 will continue to rotate until approximately 13 At 5 degrees, the restriction of cam 2250 is removed, contact spring 2220 rebounds, electromagnet 2210 is powered again, and the end of the arc-shaped alloy plate near the flipped hardener hopper 2260 (which has never been loaded with hardener) contacts the end of contact spring 2220, thus initiating the next metering and feeding cycle. The hardener poured into the hardener metering addition section shell 2300 flows along the inner wall of the hardener metering addition section shell 2300 to the planetary mixing section 1000 to participate in mixing. In the water control section 4000, water flows sequentially through the water control section inlet pipe 4400, water control section flow meter 4300, water control section butterfly valve 4100, and water control section supply pipe 4200. The water enters the planetary mixing section 1000 to participate in mixing. After the flow meter 4300 in the water control section detects a certain amount of water flow, the PLC control system sends a closing signal to the butterfly valve 4100 in the water control section. This signal causes the butterfly valve 4100 in the water control section to switch to the open circuit state. After the soil delivery is completed, the brake mechanism 1400 is adjusted to the brake state, and hydraulic oil is injected into the cylinder 1410 of the brake mechanism. The piston 1420 of the brake mechanism will be pushed as a result. The friction plate 1430 of the brake mechanism will engage with the internal gear friction plate 1520 in the planetary transmission mechanism 1500, thus locking the rotation of the gear ring 1510. The transmission mode of the planetary transmission mechanism 1500 changes, and the planet carrier 1560 begins to rotate.

[0079] S3. After completing S1 and S2, the staff observes the internal condition of the planetary mixing section 1000 through the observation window 1300 on the ladder of the auxiliary observation section 5000. After the mixing effect is ideal, the brake mechanism 1400 is released to stop the excavator from feeding soil. The butterfly valve 6100 of the fluidized soil finished product conveying section is opened. After the fluidized soil in the device is discharged, the butterfly valve 6100 of the fluidized soil finished product conveying section is closed and the S2 step is repeated.

Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
