Technical Field

[0001] This disclosure relates to the field of slag slurry treatment technology, and in particular to a flocculation and cyclone synergistic operation system. Background Technology

[0002] With the continuous advancement of urban construction, tunnel boring machine (TBM) technology is increasingly widely used in projects such as subways and tunnels. During TBM construction, a large amount of excavated soil is generated. This excavated soil typically contains mud, sand, gravel, moisture, and other impurities, and its physical and chemical properties are quite complex. Effective treatment and disposal of TBM excavated soil is not only related to construction efficiency and cost, but also has a significant impact on environmental protection and project quality.

[0003] After the initial removal of large stones and coarse sand from traditional tunnel boring machine excavation, the slurry with high water content and fine particles needs further cyclone flocculation. However, most current cyclone flocculation equipment is an integrated structure, which is bulky, difficult to transport and install, and cannot meet the usage requirements. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, the purpose of this disclosure is to provide a flocculation and cyclone co-operation system.

[0006] To achieve the above objectives, this disclosure provides a flocculation and cyclone co-operation system, comprising: a support frame; a flocculation device, wherein the flocculation device is mounted on the support frame and includes: a first tank and a second tank, the first tank and the second tank being detachably connected, and the first tank being located on top of the second tank, the liquid outlet of the first tank being used to discharge overflow liquid, and the liquid outlet of the second tank being used to discharge flocculants; and a cyclone device, wherein the cyclone device is mounted on top of the first tank, and the liquid inlet of the cyclone device is used to introduce slag slurry, the overflow end of the cyclone device being connected to the liquid inlet end of the first tank, and the underflow end of the cyclone device being used to discharge slurry with a particle size larger than a preset size.

[0010] Optionally, a second sealing gasket and / or a second sealant are provided between the fourth ring plate and the second ring plate.

[0011] Optionally, the flocculation device further includes: at least one filter press pump, the filter press pump being disposed at the bottom of the support frame, and the inlet end of the filter press pump being connected to the outlet end of the second tank, and the outlet end of the filter press pump being connected to the inlet end of the filter press equipment.

[0012] Optionally, the at least one filter press pump includes: a first pump body, a second pump body, a third pump body, and a fourth pump body. The inlet end of the first pump body is connected to the first outlet end of the second tank, and the inlet end of the second pump body is connected to the second outlet end of the second tank. The inlet end of the third pump body is connected to the third outlet end of the second tank, and the inlet end of the fourth pump body is connected to the fourth outlet end of the second tank. The outlet ends of the first, second, third, and fourth pump bodies are respectively connected to the inlet end of the filter press equipment.

[0017] Since the first tank is located on top of the second tank, and the cyclone device is installed on top of the first tank, with its overflow end connected to the inlet end of the first tank, when the slag slurry is introduced into the inlet end of the cyclone device, the cyclone device can perform cyclone separation of the slag slurry. Slurry particles larger than the preset particle size can flow by gravity into the first and second tanks for flocculation and sedimentation. Thus, the integrated flocculation device and cyclone device achieve cyclone flocculation treatment of slag slurry, which not only improves work efficiency but also makes the whole unit easy to transport separately and more convenient to install, thanks to the detachable structure between the first and second tanks. This allows it to be suitable for different construction environments and meet usage requirements.

[0027] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] like Figure 1 and Figure 2 As shown in the figure, this disclosure proposes a flocculation and cyclone co-operation system, including: a support frame 1, a flocculation device 2, and a cyclone device 3. The flocculation device 2 is mounted on the support frame 1 and includes: a first tank 21 and a second tank 22. The first tank 21 and the second tank 22 are detachably connected, and the first tank 21 is located on top of the second tank 22. The liquid outlet of the first tank 21 is used to discharge overflow liquid, and the liquid outlet of the second tank 22 is used to discharge flocculants. The cyclone device 3 is mounted on top of the first tank 21, and the liquid inlet of the cyclone device 3 is used to introduce slag slurry. The overflow end of the cyclone device 3 is connected to the liquid inlet end of the first tank 21, and the underflow end of the cyclone device 3 is used to discharge slurry with a particle size greater than a preset size.

[0029] Understandably, since the first tank 21 is located on top of the second tank 22, and the cyclone device 3 is set on top of the first tank 21, and the overflow end of the cyclone device 3 is connected to the liquid inlet end of the first tank 21, when the slag slurry is introduced into the liquid inlet end of the cyclone device 3, the cyclone device 3 can perform cyclone separation of the slag slurry, and the slurry with a particle size larger than the preset size can flow by gravity to the first tank 21 and the second tank 22 for flocculation and sedimentation. Thus, the cyclone flocculation treatment of slag slurry is realized by using the integrated flocculation device 2 and the cyclone device 3. This not only improves the work efficiency, but also makes the whole unit easy to transport separately and more convenient to install by utilizing the detachable structure between the first tank 21 and the second tank 22. Therefore, it can be applied to different construction environments and meet the usage requirements.

[0030] It should be noted that the support frame 1 is used for supporting and integrating the flocculation device 2 and the cyclone device 3. The second tank 22 is set on the support frame 1, the first tank 21 is set on the second tank 22, and the cyclone device 3 is set on the first tank 21. This realizes the integrated arrangement of the flocculation device 2 and the cyclone device 3. The specific type of the support frame 1 can be set according to actual needs and is not limited thereto. For example, the support frame 1 may include: multiple connected longitudinal beams and transverse beams, as well as reinforcing diagonal beams arranged between the longitudinal beams and transverse beams. The support frame 1 as a whole is a ring-shaped support structure.

[0031] The flocculation device 2 is used to achieve flocculation of slurry using flocculants. The first tank 21 and the second tank 22 form a split flocculation device 2. The specific types of the first tank 21 and the second tank 22 can be set according to actual needs and are not limited thereto. For example, the first tank 21 can be a ring structure and the top of the first tank 21 is provided with a sealed top plate. The second tank 22 can be an inverted cone structure, and the top of the second tank 22 is connected and communicates with the top of the first tank 21.

[0032] The cyclone device 3 is based on the principle of centrifugal sedimentation to achieve efficient separation of solid and liquid phases. The specific type of the cyclone device 3 can be set according to actual needs and there are no restrictions on it.

[0033] like Figure 3 As shown, in some embodiments, the flocculation device 2 further includes at least one third tank 23, which is detachably disposed between the first tank 21 and the second tank 22.

[0034] It is understandable that, since the third tank 23 is detachably set between the first tank 21 and the second tank 22, the flocculation device 2 can use the third tank 23 to freely increase the height of the tank, thereby achieving the purpose of expansion without involving foundation modification.

[0035] It should be noted that the third tank 23 is used for the vertical expansion of the flocculation device 2. The specific type of the third tank 23 can be set according to actual needs and there are no restrictions on it. For example, the third tank 23 can be a ring structure with a size close to that of the first tank 21.

[0036] Different numbers of third tanks 23 can achieve different capacities of flocculation device 2. For example, each additional standard section (third tank 23) can increase the throughput by 30%.

[0037] Among them, the expansion operation of the third tank 23 can adopt the in-situ jacking technology, and use the reserved socket flange interface to complete the rapid docking of the new module.

[0038] The flocculation device 2 can also be equipped with an adaptive flow control system, which can automatically adjust the dosage of reagents according to changes in the treatment volume, ensuring consistent flocculation effects at different scales. This effectively solves the industry pain points of long renovation cycles and high costs associated with traditional flocculation facilities, and is particularly suitable for scenarios requiring dynamic adjustment of treatment scale, such as municipal wastewater treatment plant upgrades and industrial park water treatment, providing an efficient solution for the full life cycle management of water treatment systems.

[0039] In some embodiments, a first ring plate is provided at the bottom of the first tank 21, and a third ring plate is provided at the top of the third tank 23, the third ring plate and the first ring plate being connected by a plurality of first bolts; a second ring plate is provided at the top of the second tank 22, and a fourth ring plate is provided at the bottom of the third tank 23, the fourth ring plate and the second ring plate being connected by a plurality of second bolts.

[0040] It is understandable that, since the bottom of the first tank 21 is provided with a first ring plate and the top of the third tank 23 is provided with a third ring plate, the third ring plate and the first ring plate are connected by multiple first bolts, so that the first tank 21 and the third tank 23 can be stably connected by the cooperation of the first ring plate and the third ring plate and the fixing of the first bolts, while also facilitating disassembly and assembly.

[0041] Since the second tank 22 is provided with a second ring plate at the top and the third tank 23 is provided with a fourth ring plate at the bottom, and the fourth ring plate and the second ring plate are connected by multiple second bolts, the second tank 22 and the third tank 23 can be stably connected by the cooperation of the second ring plate and the fourth ring plate and the fixing of the second bolts, and at the same time, it is easy to disassemble and assemble.

[0042] It should be noted that the first ring plate and the third ring plate are used to connect the first tank 21 and the third tank 23, while the second ring plate and the fourth ring plate are used to connect the second tank 22 and the third tank 23. When the third tank 23 is not arranged, the first tank 21 and the second tank 22 are connected by the first ring plate and the second ring plate. Similarly, when multiple third tanks 23 are arranged, the connected tanks are connected by the third ring plate and the fourth ring plate.

[0043] In some embodiments, a first sealing gasket and / or a first sealant are provided between the third ring plate and the first ring plate.

[0044] Understandably, the presence of a first sealing gasket and / or a first sealant between the third ring plate and the first ring plate enhances the sealing performance between them, thereby ensuring stable flocculation of the slurry by the flocculation device 2 and preventing leakage while achieving capacity expansion.

[0045] It should be noted that the first sealing gasket is used for sealing between the third ring plate and the first ring plate. The specific type of the first sealing gasket can be set according to actual needs and there is no limitation thereto. For example, the first sealing gasket can be a high-strength rubber sealing gasket.

[0046] The first sealant is used for sealing between the third ring plate and the first ring plate. The specific type of the first sealant can be set according to actual needs and is not limited thereto. For example, the first sealant can be a corrosion-resistant sealant.

[0047] In some embodiments, a second sealing gasket and / or a second sealant are provided between the fourth ring plate and the second ring plate.

[0048] Understandably, the presence of a second sealing gasket and / or a second sealant between the fourth ring plate and the second ring plate enhances the sealing performance between them, thereby ensuring stable flocculation of the slurry by the flocculation device 2 and preventing leakage while achieving capacity expansion.

[0049] It should be noted that the second sealing gasket is used for sealing between the fourth ring plate and the second ring plate. The specific type of the second sealing gasket can be set according to actual needs and there is no limitation thereto. For example, the second sealing gasket can be a high-strength rubber sealing gasket.

[0050] The second sealant is used for sealing between the fourth ring plate and the second ring plate. The specific type of the second sealant can be set according to actual needs and is not limited thereto. For example, the second sealant can be a corrosion-resistant sealant.

[0051] like Figure 1 As shown, in some embodiments, the flocculation device 2 further includes: at least one filter press pump 24, the filter press pump 24 is disposed at the bottom of the support frame 1, and the inlet end of the filter press pump 24 is connected to the outlet end of the second tank 22, and the outlet end of the filter press pump 24 is connected to the inlet end of the filter press equipment.

[0052] It is understandable that, since the inlet end of the filter press pump 24 is connected to the outlet end of the second tank 22, and the outlet end of the filter press pump 24 is connected to the inlet end of the filter press equipment, the flocculated material precipitated in the second tank 22 can be directionally transported by the filter press pump 24, thereby ensuring the efficient separation of slurry by the flocculation device 2.

[0053] It should be noted that the filter press pump 24 is used to transport flocculants by using negative pressure suction. The specific type of filter press pump 24 can be set according to actual needs and there are no restrictions on it.

[0054] like Figure 2As shown, in some embodiments, at least one filter press pump 24 includes: a first pump body 241, a second pump body 242, a third pump body 243, and a fourth pump body 244. The inlet end of the first pump body 241 is connected to the first outlet end of the second tank 22, and the inlet end of the second pump body 242 is connected to the second outlet end of the second tank 22. The inlet end of the third pump body 243 is connected to the third outlet end of the second tank 22, and the inlet end of the fourth pump body 244 is connected to the fourth outlet end of the second tank 22. The outlet ends of the first pump body 241, the second pump body 242, the third pump body 243, and the fourth pump body 244 are respectively connected to the inlet end of the filter press equipment. The first, second, third, and fourth outlet ends of the second tank 22 are evenly distributed circumferentially along the second tank 22.

[0055] Understandably, since the inlet end of the first pump body 241 is connected to the first outlet end of the second tank 22, and the inlet end of the second pump body 242 is connected to the second outlet end of the second tank 22, the inlet end of the third pump body 243 is connected to the third outlet end of the second tank 22, and the inlet end of the fourth pump body 244 is connected to the fourth outlet end of the second tank 22, and the outlet ends of the first pump body 241, the second pump body 242, the third pump body 243, and the fourth pump body 244 are respectively connected to the inlet end of the filter press, the flocculants precipitated in the second tank 22 can be efficiently transported using the first pump body 241, the second pump body 242, the third pump body 243, and the fourth pump body 244. At the same time, since the first outlet end, the second outlet end, the third outlet end, and the fourth outlet end of the second tank 22 are evenly distributed along the circumference of the second tank 22, the transport of the flocculants precipitated in the second tank 22 is more uniform.

[0056] It should be noted that the first pump body 241, the second pump body 242, the third pump body 243 and the fourth pump body 244 are all filter press pumps 24.

[0057] Among them, a multi-pump parallel system is configured at the bottom. For example, each additional filter press pump can improve the slag discharge efficiency by 25%.

[0058] The system can employ an intelligent load distribution controller to automatically adjust the start and stop of each pump based on real-time operating conditions, thereby optimizing energy consumption. The pump set interfaces are designed according to standards, supporting equipment additions without shutting down the system.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the diameter of the second tank 22 decreases linearly from the top to the bottom of the second tank 22.

[0060] It is understandable that, since the diameter of the second tank 22 decreases linearly from the top to the bottom of the second tank 22, the second tank 22 has an inverted conical structure, which facilitates the sedimentation of flocculants and ensures the efficient separation of slurry by the flocculation device 2.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the cyclone device 3 includes: a hydrocyclone 31, a regulating valve 32, and a variable frequency pump 33. The hydrocyclone 31 is disposed at the top of the first tank 21, and the overflow end of the hydrocyclone 31 is connected to the liquid inlet end of the first tank 21. The bottom flow end of the hydrocyclone 31 is used to discharge slurry with a particle size larger than a preset size. The regulating valve 32 is disposed at the bottom flow end of the hydrocyclone 31. The variable frequency pump 33 is disposed at the bottom of the support frame 1, and the liquid inlet end of the variable frequency pump 33 is used to introduce slag slurry. The liquid outlet end of the variable frequency pump 33 is connected to the liquid inlet end of the hydrocyclone 31.

[0062] It is understandable that, since the inlet end of the variable frequency pump 33 is connected to the slag slurry, and the outlet end of the variable frequency pump 33 is connected to the inlet end of the hydrocyclone 31, the slag slurry can be transported to the hydrocyclone 31 by the pressurization of the variable frequency pump 33, thereby ensuring that the hydrocyclone 31 can efficiently separate the slag slurry.

[0063] Since the regulating valve 32 is located at the underflow end of the hydrocyclone 31, the regulating valve 32 can adjust the opening of the underflow end of the hydrocyclone 31, thereby ensuring that the underflow end of the hydrocyclone 31 will not have poor flow due to a small opening, and also preventing liquid from splashing and polluting the site due to an excessive opening.

[0064] It should be noted that the hydrocyclone 31 is used to separate the slag slurry. The specific type of hydrocyclone 31 can be set according to actual needs and there are no restrictions on it.

[0065] The top of the hydrocyclone 31 is the overflow end, which outputs liquid containing small particles (not larger than the preset particle size) to the flocculation device 2. The bottom of the hydrocyclone 31 is the underflow end, which discharges slurry with large particles (larger than the preset particle size). It is equipped with wear-resistant steel pipes to extend its service life.

[0066] The regulating valve 32 is used to adjust the opening degree of the underflow end of the hydrocyclone 31. The specific type of regulating valve 32 can be set according to actual needs and is not limited thereto. For example, the regulating valve 32 can be an electric ball valve. The regulating valve 32 can support linear opening degree adjustment from 0° to 90°, the valve body sealing level reaches IP68, and it is resistant to particle impact and corrosive media. The regulating valve 32 works synchronously with the variable frequency pump 33, and the opening degree is synchronized.

[0067] The variable frequency pump 33 is used for pressurizing and conveying slag slurry. The specific type of variable frequency pump 33 can be set according to actual needs and there is no limitation. For example, the variable frequency pump 33 is driven by a variable frequency motor and the pump speed is adjusted in real time through the electronic control system (0-100% stepless speed change) to accurately control the slurry conveying pressure and ensure that the inlet pressure of the hydrocyclone 31 is stable at the process requirement threshold.

[0068] In this embodiment, the system integrates the cyclone device 3 at the top of the flocculation device 2, effectively saving installation space and time. The specific operating process is as follows: the slag slurry to be screened, flocculated, and precipitated is transported through a pipeline by the frequency converter pump 33 into the cyclone separator 31 via the feed pipeline. The slurry with smaller particles that requires flocculation flows through the overflow end at the top of the cyclone separator 31 into the first tank 21, while the slurry containing larger particles is discharged through the bottom flow end of the cyclone separator 31. After sedimentation, the upper clear liquid of the liquid entering the flocculation device 2 flows out through the overflow pipe at the outlet end of the first tank 21, and the lower flocculent is transported to the filter press by the filter press pump 24.

[0069] Therefore, by using the "cyclone pre-classification + flocculation" process, the installation site can be reduced and reused, and the consumption of reagents can be effectively reduced, thereby improving the dewatering rate of slag and soil.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the system further includes a ladder 4, which is disposed at the top of the first tank 21 and extends to the bottom of the second tank 22.

[0071] Understandably, since the ladder 4 is located at the top of the first tank 21 and extends to the bottom of the second tank 22, it allows workers to climb from the ground to the top of the first tank 21, thus facilitating the inspection and maintenance of the system.

[0072] like Figure 1 and Figure 2 As shown, in some embodiments, the system further includes a guardrail 5, which is disposed on the top of the first tank 21.

[0073] Understandably, since the guardrail 5 is located at the top of the first tank 21, it can provide protection at the top of the first tank 21, thereby reducing the risk of falling.

[0074] It should be noted that in the description of this disclosure, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
