Description

Technical Field

[0001] This invention relates to the field of mud treatment technology, and in particular to an intensive mud separation tank suitable for construction platforms. Background Technology

[0002] In the field of construction, especially in the process of pile foundation construction, a large amount of mud containing impurities such as mud, sand and stone debris is generated. If this mud is discharged directly without effective treatment, it will not only cause serious pollution to the surrounding environment, such as blocking river channels and damaging soil structure, but may also face heavy penalties for violating environmental protection regulations. At the same time, untreated mud cannot be recycled, leading to increased construction costs and serious waste of resources.

[0003] Currently, commonly used mud treatment methods at construction sites have many drawbacks. Traditional mud sedimentation tanks require large areas, have long treatment cycles, and limited treatment effectiveness. Large amounts of mud generated during construction naturally settle in the sedimentation tank, requiring a considerable amount of time for impurities such as silt and sand to settle to the bottom. During this period, fine particles in the mud are difficult to completely settle, resulting in treated mud still containing many impurities and failing to meet the requirements for recycling. Furthermore, cleaning the sedimentation tank requires significant manpower and time, and the cleaning process easily causes secondary pollution. While some simple mud separation equipment can improve mud treatment efficiency to some extent, these devices mostly only perform preliminary coarse filtration of large stones and other particles in the mud, failing to effectively remove fine particulate impurities. The quality of the treated mud is unstable and cannot meet high-standard construction requirements. Moreover, during operation, these devices are prone to mud splashing, producing odors that adversely affect the construction site environment and the health of operators. Based on the above, we propose an intensive mud separation tank suitable for construction platforms to solve these problems. Summary of the Invention

[0004] This invention provides an intensive mud separation tank suitable for construction platforms to solve the problem of poor mud treatment effect in the prior art.

[0005] The technical problem solved by this invention is achieved by the following technical solution:

[0006] An intensive mud separation tank suitable for construction platforms includes a sealable tank body, a screening mechanism, a cyclone separation mechanism, and a dosing mechanism. The sealable tank body includes a tank box and a tank cover detachably connected to the top of the tank box. The interior of the tank box is divided into a slag discharge chamber, a slurry discharge chamber, and a slurry mixing chamber by a partition plate. The output end of the screening mechanism is located in the slag discharge chamber, which is used to allow large pieces of slag and mud to fall into the slag discharge chamber and the slurry discharge chamber respectively after screening. The output end of the slag discharge chamber is connected to the slag discharge chamber. The input end of the cyclone separation mechanism is connected to the slurry discharge chamber through a slurry discharge pipe, and a first pump body is provided on the slurry discharge pipe. The mud output port of the cyclone separation mechanism is located in the slurry mixing chamber. The slag output port of the cyclone separation mechanism is connected to the slag discharge chamber. The output end of the dosing mechanism is connected to the slurry mixing chamber, which is used to add chemicals to the slurry mixing chamber for mixing with the mud.

[0007] Preferably, the end of the mud outlet is provided with a mud distribution cover, and the mud distribution cover is provided with spray holes at equal intervals around its circumference.

[0008] Preferably, a baffle is provided outside the mud outlet, and there is an angle between the axial extension direction of the spray hole and the axial extension direction of the baffle, so as to generate turbulence after the mud sprayed from the spray hole impacts the baffle plate, thereby achieving mixing of mud and reagent.

[0009] Preferably, the dosing mechanism includes a conveying cylinder, the interior of which is connected to a first conveying auger via a first driving component, the output end of which is located in the mixing chamber, and a loading cylinder for holding the agent is provided on the conveying cylinder.

[0010] Preferably, the screening mechanism includes a screening plate that is rotatably connected to the inner wall of the tank and is inclined, and a rotating shaft that is rotatably connected to the bottom of the screening plate. An eccentric wheel for pushing the screening plate to rotate is connected to the rotating shaft, and the rotating shaft is driven by a second driving member located outside the tank.

[0011] Preferably, it also includes an odor treatment mechanism provided on the pool cover, the odor treatment mechanism including an exhaust fan and an air hood installed inside the pool cover and connected to the input end of the exhaust fan, the output end of the exhaust fan being connected to an odor purification mechanism.

[0012] Preferably, the slag discharge bin is equipped with a second conveying auger for discharging the slag and stones separated from the cyclone separation mechanism and the slag discharge bin.

[0013] Preferably, the discharge pipe is equipped with a concentration detection component, which includes a programmable logic controller and a microwave concentration meter and a laser particle size analyzer electrically connected to the programmable logic controller. When the concentration detection component detects that the mud concentration in the discharge pipe is not within the set threshold, the programmable logic controller controls the first pump body to increase the feed pressure of the cyclone separator.

[0014] The beneficial effects of this invention are as follows: through the enclosed tank partition design, the linkage between screening and cyclone separation mechanisms, the precise control of the dosing mechanism, and the adaptive adjustment of the concentration detection component, the entire mud treatment process is integrated and intelligent. The enclosed tank reduces the spread of odors, and the partitioned structure optimizes the slurry separation path. The screening mechanism quickly separates large pieces of slag from the mud, and the cyclone separation mechanism further refines and classifies the mud, reducing the load on the slag discharge bin. At the same time, the separated mud is dosed with chemicals as needed, making the mud recyclable. Then, the concentration detection component monitors the mud concentration in the discharge pipe in real time and automatically adjusts the feed pressure of the cyclone separation mechanism, improving separation efficiency and mud quality stability. This solves the problems of low efficiency and high risk of secondary pollution in traditional mud separation, achieving the technical effects of efficient slurry separation, mud recycling, and environmentally friendly construction.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0025] Reference Figures 1-7 As shown, an intensive mud separation tank suitable for construction platforms includes a sealable tank body 1. The sealable tank body 1 includes a tank box 11 and a tank cover 12 detachably connected to the top of the tank box 11. The tank body is welded from steel plates and has external reinforcing ribs to ensure structural strength and sealing. In use, the tank body can be hoisted to the vicinity of the construction platform, and then the tank cover 12 can be installed on the tank box 11. Since the construction platform may change position with the movement of the pile foundation, hoisting the sealable tank body 1 provides greater flexibility and facilitates use. Inside the tank box 11, a partition plate 13 divides it into a slag discharge chamber 14 and a slurry discharge chamber 15. 5 and mixing chamber 16, the tank 11 is also equipped with screening mechanism 2, cyclone separation mechanism 3 and dosing mechanism 4. The output end of screening mechanism 2 is located in slag dropping chamber 14, which is used to make large pieces of slag and mud fall into slag dropping chamber 14 and slurry discharge chamber 15 respectively after screening. The output end of slag dropping chamber 14 is connected to slag discharge chamber 5. The input end of cyclone separation mechanism 3 is connected to slurry discharge chamber 15 through slurry discharge pipe 31. The slurry discharge pipe 31 is equipped with first pump body 32. The mud output port 34 of cyclone separation mechanism 3 is located in mixing chamber 16. The slag output port 33 of cyclone separation mechanism 3 is connected to slag discharge chamber 5.

[0026] Specifically, the slurry generated during pile foundation construction is transported to the pool tank 11 via an external pump. It first undergoes preliminary screening by the screening mechanism 2, where larger particles of slag and other materials are intercepted and screened, falling into the slag discharge bin 14. The screened slurry falls into the discharge bin 15, where it is pressurized by the first pump body 32 and then enters the cyclone separator 3 for further separation. The cyclone separator 3 includes a conical cylinder with a tangential feed inlet at the top connected to the discharge pipe 31. During operation, the slurry enters the cyclone separator 3 tangentially under the pressure of the first pump body 32, forming a high-speed rotating flow field. Due to centrifugal force, denser slag particles are thrown against the cylinder wall and slide down the conical section from the bottom of the slag discharge bin. The mud is discharged from outlet 33 into the slag discharge bin 5; the less dense mud converges towards the center and flows out through the mud outlet 34 at the top into the mixing bin 16, achieving secondary separation treatment of the mud. However, if the mud after secondary treatment cannot meet the construction requirements, such as insufficient viscosity or too thin mud, and cannot play a role in wall protection or suspension of drill cuttings in pile foundation construction, a chemical agent prepared by mixing bentonite, water, and additives (such as dispersants and thickeners) in a specific ratio can be added into the mixing bin 16 through the dosing mechanism 4. After adding bentonite and thickener, the concentration of mud colloidal particles increases, forming a network structure to repair the mud performance. Then, the treated mud is pumped out by an external pump for recycling.

[0027] Reference Figures 6-7 As shown, furthermore, in order to fully mix the added reagent with the mud in the mixing chamber 16, a slurry distribution hood 6 is provided at the end of the mud outlet 34. The slurry distribution hood 6 has spray holes 61 equidistantly spaced around its circumference. A baffle hood 62 is provided outside the mud outlet 34. There is an angle between the axial extension direction of the spray holes 61 and the axial extension direction of the baffle hood 62, which can be 30° to 60°. This angle is used to generate turbulence after the mud sprayed from the spray holes 61 impacts the baffle plate, thereby achieving the mixing of mud and reagent. The slurry distribution hood 6 is an inverted truncated cone structure. The mud separated by the cyclone separation mechanism 3 is sprayed out from the spray holes 61 at a high flow rate. After multiple jets impact the baffle plate of the baffle hood 62, they scatter in all directions, forming strong turbulence. The turbulence drives the mud in the mixing chamber 16 to circulate. At the same time, the reaction force generated by impacting the baffle plate causes the mud to form an up-and-down tumbling stirring effect in the mixing chamber 16, thereby achieving the mixing of mud and reagent.

[0028] The dosing mechanism 4 includes a conveying cylinder 41. The inside of the conveying cylinder 41 is connected to a first conveying auger 43 via a first driving member 42. The output end of the conveying cylinder 41 is located inside the mixing chamber 16. The conveying cylinder 41 is equipped with a loading cylinder 44 for holding the agent. The agent to be added is placed in the loading cylinder 44, and then the first driving member 42 drives the first conveying auger 43 to rotate, so as to add the agent into the mixing chamber 16.

[0029] Reference Figures 2-3 As shown, the screening mechanism 2 further includes a screening plate 21 rotatably connected to the inner wall of the tank 11 and inclined, and a rotating shaft 22 rotatably connected to the bottom of the screening plate 21. An eccentric wheel 23 for pushing the screening plate 21 to rotate is connected to the rotating shaft 22. The rotating shaft 22 is driven by a second driving member 24 located outside the tank. The output end of the screening plate 21, i.e. the lower end, is located in the slag discharge bin 14. The second driving member 24 drives the rotating shaft 22 and the eccentric wheel 23 to rotate, so that the eccentric wheel 23 continuously pushes the screening plate 21 to swing around the hinge point, so that the large particles of slag intercepted above the screening plate 21 fall into the slag discharge bin 14 and then fall into the slag discharge bin 5.

[0030] The slag in the slag discharge bin 5 collects the slag in the slag discharge bin 14 and the slag separated by the cyclone separator 3. The collected slag is then discharged by the second conveying auger 51 in the slag discharge bin 5. During construction, engineering vehicles can be set up to collect the discharged slag and transport it to a designated location for processing. Both the first drive unit 42 and the second drive unit 24 can be driven by a geared motor or other device. The second conveying auger 51 can be driven by the same method as the first conveying auger 43.

[0031] During the mud treatment process in bridge pile foundation construction, the decomposition of organic matter (such as plant and animal remains and microbial metabolic products) and the release of gases such as sulfides (hydrogen sulfide, etc.) and ammonia in the mud will produce odors. Direct discharge of these gases will pollute the surrounding environment. Therefore, referring to... Figures 1-5 As shown, the pool cover 12 is also equipped with an odor treatment mechanism, which includes an exhaust fan 7 and an air hood 71 installed inside the pool cover 12 and connected to the input end of the exhaust fan 7. The output end of the exhaust fan 7 is connected to an odor purification mechanism 72. The air hood 71 is an inverted funnel-shaped structure, integrally formed from 304 stainless steel, and its top is connected to the input end of the exhaust fan 7 through a sealing flange. The exhaust fan 7 can be an explosion-proof centrifugal fan with a rated air volume of 3000 m³ / h. 3 / h, wind pressure 2500Pa, the odor purification mechanism 72 can be composed of multi-stage treatment units arranged in series, namely activated carbon adsorption box and biological filter. During operation, the odor gas generated during the mud treatment process is evenly collected by the exhaust hood 71 and introduced into the exhaust fan 7 under the negative pressure of the exhaust fan 7. The gas first enters the activated carbon adsorption box, which is filled with honeycomb activated carbon. Through its internal porous structure, it adsorbs small molecule odor substances such as hydrogen sulfide and ammonia. Then it enters the biological filter for further filtration and purification, so that the final emission gas meets the standards and reduces pollution to the air environment.

[0032] Reference Figure 3As shown, a concentration detection component is further provided on the discharge pipe 31. The concentration detection component includes a programmable logic controller 8 and a microwave concentration meter 81 and a laser particle size analyzer 82 electrically connected to the programmable logic controller 8. When the concentration detection component detects that the mud concentration in the discharge pipe 31 is not within the set threshold, the programmable logic controller 8 controls the first pump body 32 to increase the feed pressure of the cyclone separator 3. The microwave concentration meter 81 is installed in the middle section of the discharge pipe 31 through a flange to monitor the mud mass concentration in real time. The sampling probe of the laser particle size analyzer 82 is inserted into the discharge pipe. Inside unit 31, particle concentration is detected. Both the microwave concentration meter 81 and the laser particle size analyzer 82 are electrically connected to the programmable logic controller 8 via a communication line. When the concentration threshold detected by the microwave concentration meter 81 and the laser particle size analyzer 82 is not within the specified threshold, the programmable logic controller 8 controls the frequency output of the inverter in the first pump body 32, increasing the feed pressure of the cyclone separator 3. The slurry enters the tangential feed inlet of the cyclone separator at a higher pressure, causing it to rotate at a faster speed along the inner wall of the separator, enhancing the centrifugal separation effect. The increased feed pressure also increases the slurry flow rate entering the cyclone separator per unit time. More slurry rotates at high speed within the separator, forming a stronger rotating flow field, further intensifying the centrifugal motion of the particles.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
