Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of shield tunnel foam agent refining and filtration equipment, specifically, to a shield tunnel foam agent refining and filtration equipment. Background Technology

[0002] Currently, earth pressure balance (EPB) shield tunneling has become the mainstream method for urban subway construction in my country. Foamed soil conditioners, as excellent soil conditioners, occupy a dominant position in EPB shield soil improvement technology due to their combination of practicality and economy, and have broad application prospects. For foamed soil conditioners used in EPB shield tunneling, stability is a crucial performance characteristic. When foamed soil conditioners are used in the shield tunneling process, depending on the on-site construction, the foaming system releases foam, which mixes with the soil for improvement, with a time interval of approximately 2-3 minutes. During the production of foamed soil conditioners for shield tunneling, the foaming ratio and foaming stability need to be tested, and the foamed soil conditioner needs to be filtered during the production process.

[0003] Currently, when filtration equipment is in operation, the impurities filtered out will stick firmly to the filter screen of the filtration mechanism. As the equipment continues to run for a long time, the filter screen will become thicker and thicker with impurities, eventually resulting in a significant reduction in the overall filtration effect.

[0036] like Figures 1-4 As shown, it illustrates a shield tunnel foam agent refining and filtration device according to an embodiment of the present disclosure, comprising:

[0037] A platform 1 and a pair of uprights 2, both of which are fixed to the surface of the platform 1;

[0038] The filter box 3 and the separation filter assembly 5 are rotatably connected between the uprights 2 via a rotating shaft, and the separation filter assembly 5 is installed in the filter box 3.

[0039] Flushing assembly 7 is installed on filter box 3;

[0040] The support 4 and the dispersing feed assembly 6 are provided. The support 4 is fixed on the surface of the frame 1, and the dispersing feed assembly 6 is mounted on the support 4.

[0041] Differentiated collection component 8 is disposed on both sides of the platform 1;

[0042] The separation filter assembly 5 includes a rectangular opening 5-1, which is located at the bottom of the filter box 3. A slot 5-2 is provided on the side surface of the filter box 3, and a filter screen 5-3 is inserted into the slot 5-2. A gap is left between the side end face of the filter screen 5-3 and the rectangular opening 5-1. A first motor 5-4 is provided on the side surface of the support frame 2. The output end of the first motor 5-4 is connected to the rotating shaft of the filter box 3. A second motor 5-5 is fixedly connected to the side surface of the filter box 3. A pair of baffles 5-6 are provided at the bottom of the filter box 3. A material distribution plate 5-7 is rotatably connected between the baffles 5-6 through a rotating shaft. The rotating shaft of the material distribution plate 5-7 is connected to the output end of the second motor 5-5.

[0043] In some examples, a separation and filtration assembly 5 is designed to achieve the separation and filtration of foaming agents. The filter box 3 of this assembly has a rectangular opening 5-1 at its bottom, and a slot 5-2 is formed on the side surface of the filter box 3. A filter screen 5-3 is inserted into the slot 5-2, facilitating the installation and removal of the filter screen 5-3 and enabling cleaning, replacement, and other maintenance operations. A gap is left between the side end face of the filter screen 5-3 and the rectangular opening 5-1, allowing impurities to be discharged when the filter box 3 rotates to the other side. A first motor 5-4 is mounted on the side surface of the support frame 2, and its output end is connected to the rotation shaft of the filter box 3. When the first motor 5-4 starts, it drives the filter box 3 to rotate around the rotating shaft, allowing it to tilt to the other side to assist in flushing and removing impurities. The side surface of the filter box 3 is fixedly connected to the second motor 5-5. A pair of baffles 5-6 are provided at the bottom of the filter box 3. A material distribution plate 5-7 is rotatably connected between the baffles 5-6 via a rotating shaft. The rotating shaft of the material distribution plate 5-7 is connected to the output end of the second motor 5-5. When the second motor 5-5 is working, it drives the material distribution plate 5-7 to rotate around the rotating shaft. By adjusting the angle of the material distribution plate 5-7, the material distribution plate 5-7 is used to ensure that the filtered foaming agent and impurities are discharged in a concentrated manner.

[0044] like Figures 1-4As shown, this embodiment proposes a distributed feeding assembly 6, which includes a feeding pipe 6-1. The feeding pipe 6-1 is set on the side surface of the upright 2. A feeding cover 6-2 is set on the top of the feeding pipe 6-1. The feeding cover 6-2 is connected to the feeding pipe 6-1. A spiral auger 6-3 is installed inside the feeding pipe 6-1. The spiral auger 6-3 is rotated by a motor. Several discharge ports 6-4 are opened at the bottom of the feeding pipe 6-1.

[0045] In some examples, to achieve uniform dispersion of the foaming agent, a dispersion feeding component 6 is designed. A feeding pipe 6-1 is provided on the side surface of the support frame 2, and a feeding hood 6-2 is provided on the top of the feeding pipe 6-1. The feeding hood 6-2 is connected to the feeding pipe 6-1. The feeding hood 6-2 increases the inlet area of ​​the feeding pipe, making it easier for operators to feed the material. A spiral auger 6-3 is installed inside the feeding pipe 6-1. The spiral auger 6-3 is controlled by a motor to rotate. When the motor starts, the spiral auger 6-3 rotates accordingly. During its rotation, it can continuously push the material along the feeding pipe 6-1. Through the pushing action of the spiral auger 6-3, several discharge ports 6-4 are opened at the bottom of the feeding pipe 6-1, and the material will be evenly dispersed and discharged from each discharge port 6-4.

[0046] like Figures 1-4 As shown, this embodiment proposes a flushing assembly 7, which includes a water pump 7-1. The water pump 7-1 is installed on the side surface of the filter box 3. A transverse pipe 7-2 is rotatably connected inside the filter box 3. The transverse pipe 7-2 is connected to the output end of the water pump 7-1. Several nozzles 7-3 are provided at the bottom of the transverse pipe 7-2. A third motor 7-4 is provided on the side surface of the filter box 3. The output end of the third motor 7-4 is connected to the transverse pipe 7-2.

[0047] In some examples, a flushing assembly 7 is designed to effectively flush the inside of the filter box 3. A water pump 7-1 is installed on one side of the filter box 3. A transverse pipe 7-2 is rotatably connected inside the filter box 3, and the transverse pipe 7-2 is connected to the output end of the water pump 7-1. Several nozzles 7-3 are installed at the bottom of the transverse pipe 7-2. When liquid reaches the nozzles 7-3 through the transverse pipe 7-2, the nozzles 7-3 will spray the liquid out at a certain pressure and angle, thereby flushing the inside of the filter box 3. A third motor 7-4 is also installed on the side surface of the filter box 3. The output end of the third motor 7-4 is connected to the transverse pipe 7-2. When the third motor 7-4 is started, it will drive the transverse pipe 7-2 to rotate. The rotation of the transverse pipe 7-2 can further expand the flushing range of the nozzles 7-3.

[0048] like Figures 1-4As shown, this embodiment proposes a separate collection component 8, which includes an outer groove 8-1. The outer groove 8-1 is opened on one side surface of the platform 1. A foam collection box 8-2 is slidably inserted into the outer groove 8-1. A pulley 8-3 is installed at the bottom of the foam collection box 8-2. An impurity collection box 8-4 is provided at the bottom of the platform 1. The top of the impurity collection box 8-4 is an open structure. The foam collection box 8-2 and the impurity collection box 8-4 are located on the two sides of the platform 1, respectively. A drainage pipe 8-5 is provided at the bottom of the impurity collection box 8-4.

[0049] In some examples, a separation and collection component 8 is designed to distinguish and collect foaming agents and impurities. This component includes an outer trough 8-1, which is opened on one side surface of the frame 1. A foam collection box 8-2 is slidably inserted into the outer trough 8-1, and a pulley 8-3 is installed at the bottom of the foam collection box 8-2 to facilitate cleaning of the collected foam or replacement of the collection box. An impurity collection box 8-4 is set at the bottom of the frame 1. The top of the impurity collection box 8-4 has an open structure to facilitate impurities falling directly into the box. The foam collection box 8-2 and the impurity collection box 8-4 are located on the two sides of the frame 1, respectively. A drain pipe 8-5 is set at the bottom of the impurity collection box 8-4 to discharge impurities.

[0050] For example, such as Figure 4 As shown, the bottom of the feed pipe 6-1 has an arc-shaped transition structure.

[0051] In some examples, an arc-shaped transition structure is used in conjunction with the conveying structure of the auger 6-3.

[0052] For example, such as Figure 2 As shown, the bottom of the impurity collection box 8-4 has an inclined structural surface.

[0053] In some examples, the inclined structural surface facilitates the concentration of impurities in one location for complete discharge.

[0054] In actual use, the operator feeds the shield foam agent to be filtered into the feeding hood 6-2, and the material enters the feeding pipe 6-1. The motor controlling the auger 6-3 is started, and the auger 6-3 begins to rotate, pushing the material within the feeding pipe 6-1. The material is then evenly dispersed into the filter box 3 from the discharge port 6-4 at the bottom of the feeding pipe 6-1. The filter screen 5-3 in the filter box 3 filters the foam agent. The filtered foam agent passes through the filter screen 5-3 and is guided by the distribution plate 5-7 to the foam collection box 8-2. When a certain amount of impurities accumulate in the filter box 3, the first motor 5-4 is started, causing the filter box 3 to rotate and tilt to the other side. Impurities are discharged from the gap between the side end face of the filter screen 5-3 and the rectangular opening 5-1, falling into the impurity collection box 8-4. The second motor 5-5 is then started, causing the distribution plate 5-7 to rotate. The angle of the distribution plate 5-7 is adjusted to ensure that the filtered foam agent and impurities are properly separated. The wastewater is discharged in a concentrated manner. During flushing, the water pump 7-1 is activated, which transports the liquid to the horizontal pipe 7-2. The liquid is sprayed out through the nozzle 7-3 to flush the inside of the filter box 3. The third motor 7-4 is activated, which drives the horizontal pipe 7-2 to rotate, expanding the flushing range of the nozzle 7-3 and thoroughly removing the impurities remaining in the filter box 3. The wastewater and impurities generated during flushing fall into the impurity collection box 8-4 through the rectangular opening 5-1 and are discharged through the drain pipe 8-5. When the foam collection box 8-2 is full or needs to be cleaned, it can be pulled out from the outer tank 8-1 by the pulley 8-3 for treatment.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
