Description

Technical Field

[0001] The present invention relates to the technical field of foam liquid preparation, and specifically to an energy-saving integrated machine for preparing foam liquid of a shield machine. Background Art

[0002] Firstly, foam liquid can lubricate the contact surface between the cutter head of the shield machine and the soil, reduce the friction coefficient, improve the lubricity between the cutter head and the soil, thereby reducing the resistance when the cutter head of the shield machine cuts the soil, reducing the wear degree of the cutters, prolonging the service life of the cutters, and further reducing the construction interruption time caused by replacing the cutters and improving the construction efficiency. Secondly, in sandy soil layers, the foam liquid can enhance the cohesion of the soil and prevent the sandy soil from collapsing during the tunneling process of the shield machine, ensuring the safety and stability of the construction. Thirdly, for some strata with high water content, the foam liquid can play a certain role in water stoppage and reduce the impact of groundwater on the construction.

[0003] However, traditional foam liquid preparation equipment has many drawbacks. From the structural aspect, its components are numerous and the connections are complex. The coordinated work between various subsystems relies on a large number of mechanical transmissions and electrical control components, which not only increases the manufacturing cost of the equipment but also makes the equipment prone to failures during operation and difficult to repair. In terms of energy consumption, traditional equipment usually uses a motor with constant-speed drive. Regardless of the actual demand for foam liquid preparation, the motor always runs at a constant speed, resulting in a large amount of electrical energy being wasted during low-demand periods. Moreover, the design of the mixing and stirring device is unreasonable, and the shape and movement mode of the stirring blades cannot achieve sufficient and efficient mixing of the foaming agent and water, resulting in poor uniformity of the prepared foam liquid and directly affecting its use effect in shield construction.

[0023] Embodiment 1: To solve the problem in the prior art that traditional devices usually use motors with constant-speed drive, and no matter what the actual demand for the preparation of foam liquid is, the motor always runs at a constant speed, which results in a large amount of electrical energy being wasted during low-demand periods, please refer to Figures 1-9 , the present invention provides a technical solution: An energy-saving integrated machine for preparing shield machine foam liquid, comprising a mixing tank 1 and a bracket 2 fixedly connected to the bottom of the mixing tank 1. A tank cover 3 is installed on the top of the mixing tank 1. A heat insulation plate 102 is fixedly connected to the inner wall of the mixing tank 1.

The storage battery is electrically connected to various sensor elements inside the mixing tank 1. A sealing valve 301 is fixedly installed on the top of the tank cover 3. A spray pipe 305 is fixedly connected to the bottom of the sealing valve 301. A communicating pipe 302 is fixedly connected to the top of the sealing valve 301. One end of the communicating pipe 302 away from the sealing valve 301 is fixedly connected to a vertical pipe 303. A valve 304 is installed at the bottom end of the vertical pipe 303.

[0024] After the preparation is completed, open the valve 304, introduce water, and the water flow passes through the vertical pipe 303, through the communicating pipe 302, and sprays out from the spray pipe 305 to wash the inside of the mixing tank 1.

[0025] A stirring device is arranged inside the mixing tank 1. The stirring device includes a mixing mechanism and an energy-saving mechanism; The mixing mechanism includes a motor 6, a reducer 601, a rotating shaft 602, and a stirring plate 603. The reducer 601 is fixedly installed on the top of the tank cover 3. The motor 6 is installed on the top of the reducer 601. The rotating shaft 602 is connected to the output end of the reducer 601. The stirring plate 603 is connected to the outer surface of the rotating shaft 602. A mixing blade 604 is fixedly connected to one end of the stirring plate 603 away from the rotating shaft 602.

The spoiler 605 can form different stirring speeds, further enhancing the turbulence degree of the mixed liquid and improving the mixing effect. The model of the motor 6 is the GA25-370 brushed DC reduction motor.

[0026] The energy-saving mechanism includes a connecting gear 607, a speed-increasing gear 608, a connecting shaft 609, a bearing seat 610 and a generator 611. The connecting gear 607 is fixedly connected to the outer surface of the rotating shaft 602 near the top. The bearing seat 610 is fixedly installed on the top of the tank lid 3. The generator 611 is installed on the top of the bearing seat 610. The connecting shaft 609 is connected to the bottom of the generator 611. The speed-increasing gear 608 is fixedly connected to the bottom of the outer surface of the connecting shaft 609. The connecting gear 607 and the speed-increasing gear 608 are meshed and connected. The transmission ratio of the connecting gear 607 and the speed-increasing gear 608 is 1:20. The top end of the connecting shaft 609 passes through the bearing inside the bearing seat 610 and is connected to the input end of the generator 611.

[0027] During the rotation of the rotating shaft 602, it will drive the connecting gear 607 to rotate. The connecting gear 607 drives the speed-increasing gear 608 meshed with it to rotate. The speed-increasing gear 608 drives the central connecting shaft 609 to rotate. The connecting shaft 609 is connected to the input end of the generator 611. Therefore, the generator 611 can generate electricity during the stirring and mixing process. The generated alternating current is converted into direct current through an inverter and stored inside the storage battery. Then, the storage battery supplies power to various monitoring sensor components inside the mixing tank 1, achieving the effect of energy saving.

[0028] Fixed magnets 606 are fixedly connected to the outer surface of the mixing blade 604. A liquid storage pipe 7 is arranged outside the mixing tank 1. A partition plate 701 is fixedly connected to the inner wall of the liquid storage pipe 7. The top of the liquid storage pipe 7 is rotatably connected to a stirring rod 703. The top end of the stirring rod 703 is fixedly connected to a rotating rod 702. A diversion pipe 704 is fixedly connected to the right side of the liquid storage pipe 7. One end of the diversion pipe 704 away from the liquid storage pipe 7 passes through the mixing tank 1 and extends into the inner tank body 101. Coolant is stored inside the liquid storage pipe 7. By rotating the stirring rod 703 to drive the rotating rod 702 to rotate, the coolant can be stirred, and the coolant inside the liquid storage pipe 7 enters the inside of the diversion pipe 704.

[0029] An opening is provided at the right end of the diversion pipe 704. A one-way valve 7041 is fixedly installed at the opening. A telescopic spring 7044 is fixedly connected to the left side of the inner wall of the diversion pipe 704. One end of the telescopic spring 7044 is fixedly connected to a movable magnet 7043. A limiting block 7042 is fixedly connected to the inside of the diversion pipe 704. Through holes are formed on the surface of the limiting block 7042. A gap is left between the outer surface of the movable magnet 7043 and the inner wall of the diversion pipe 704. The space between the movable magnet 7043 and the limiting block 7042 is filled with coolant. One side of the movable magnet 7043 close to the fixed magnet 606 attracts each other. The one-way valve 7041 only allows liquid to flow out from the inside of the diversion pipe 704. A liquid inlet valve is arranged on the surface of the diversion pipe 704.

[0030] During the rotation of the mixing blade 604, the fixed magnet 606 will be driven to rotate. During the rotation of the fixed magnet 606, it will pass by the diversion pipe 704. When the fixed magnet 606 approaches during rotation, it will attract the movable magnet 7043 to approach, thereby pulling the movable magnet 7043 to slide inside the diversion pipe 704 through the attraction force. When sliding, the telescopic spring 7044 will be stretched and elongated. During the sliding process, the movable magnet 7043 will push the coolant to flow. The flowing coolant will pass through the through holes on the surface of the limit block 7042, enter the right side of the limit block 7042, and finally flow out from the one-way valve 7041 and enter the inside of the mixing tank 1. The coolant can, when mixing some temperature-sensitive foaming agents and water, control the temperature during the mixing process by adjusting the temperature of the medium in the mixing tank 1, preventing the foaming agent from failing or the mixing effect from being poor due to temperature changes.

[0031] When the fixed magnet 606 gradually moves away from the diversion pipe 704, the attraction force of the fixed magnet 606 on the movable magnet 7043 weakens. Under the action of the self-restoring force of the telescopic spring 7044, the movable magnet 7043 will be pulled back to its original position, thereby further pushing the coolant.

[0032] Embodiment 2: In order to further enhance the stirring and mixing effect, a fixed box body 6031 is fixedly connected to the surface of the stirring plate 603 in this application. A through groove 6032 is provided on the surface of the fixed box body 6031. A sliding rod 6034 is fixedly connected to the inside of the fixed box body 6031. A slider 6035 is slidably connected to the outer surface of the sliding rod 6034. Mixing plates 6036 are fixedly connected to both sides of the slider 6035. The stirring plate 603 is bolted to the rotating shaft 602, and the stirring plate 603 is bolted to the mixing blade 604. The stirring plate 603 is inclined at 30 degrees. The 30-degree inclination can reduce the resistance during stirring on the premise of ensuring the mixing effect, thereby reducing power consumption. The mixing plates 6036 penetrate through the through groove 6032.

[0033] During the rotation of the rotating shaft 602, the stirring plate 603 and the fixed box body 6034 will be driven to rotate. Under the action of centrifugal force, the slider 6035 inside the fixed box body 6031 will slide on the surface of the sliding rod 6034, thereby driving the mixing plates 6036 to slide, forming different stirring directions and speeds, and forming a complex stirring flow field to ensure that the foaming agent and water can be fully mixed in a short time.

[0034] Working principle: When preparing the foam mixture for the shield machine, first put the prepared raw materials into the mixing tank 1 from the feed pipe 4, and then start the motor 6. The output shaft of the motor 6 drives the rotating shaft 602 to rotate through the speed reducer 601. The rotating shaft 602 drives the stirring plate 603 to rotate. The stirring plate 603 drives the mixing blade 604 to mix and stir various materials. The foam mixture after mixing flows out from the liquid outlet pipe 8.
