[0031] A second pipeline having one end communicated with the float switch and the other end extended out of the liquid storage cavity.

[0032] The utility model has the following working principles and advantages:

[0033] The utility model discloses, in order to solve the problem of the traditional mud processing equipment of related art, the volume is big, the weight is heavy, is not easy to use in special terrain environment, the embodiment supplies the pump body of slurry and beating pulp, reduces the number of whole equipment pump body, reaches the purpose of lightweight equipment.

[0034] The rack is in the shape of a cuboid, and has a liquid storage cavity inside. The bottom of the liquid storage cavity is designed with a certain slope to facilitate the flow and concentration of slurry in the cavity. The screening member has a screen structure, and the screen holes can effectively remove impurity particles of different particle sizes in the mud. The slurry can flow into the liquid storage cavity from the screening member. The pump body is placed at the lowest point of the bottom of the liquid storage cavity and is fixed by a fixed support to prevent displacement during operation. The pump body is a centrifugal pump with high lift, large flow and light weight, and is made of a composite structure of corrosion-resistant engineering plastic and metal, which reduces the weight while ensuring performance. The first pipeline inlet is tightly connected to the outlet of the pump body. The first outlet of the first pipeline leads to the screening member for secondary screening of the slurry in the liquid storage cavity. The second outlet is connected to the subsequent mud conveying pipeline or mud storage container for outputting the processed qualified mud.

[0035] The original mud is transported to the top of the screening member by an external conveying device, and the mud enters the liquid storage cavity through the screening member under the action of gravity. Larger impurity particles are intercepted by the screen and accumulated on the screen. The slurry is sprayed onto the screen again through the first outlet of the first pipeline for secondary treatment. The screened mud flows into the liquid storage cavity, and the pump body is started to pump the mud in the liquid storage cavity. The mud is transported to the construction area or the next mud treatment process through the second outlet to realize the slurry supply function. Since the slurry supply and beating pulp share one pump body, the number of pumps in the equipment is reduced, thereby reducing the weight and volume of the entire mud treatment system.

[0036] By sharing one pump body for slurry supply and beating pulp, at least one pump body is reduced compared to the traditional mud treatment system with separate slurry supply pump and beating pump. After reducing one pump body, the weight of this part is directly reduced, which significantly reduces the weight of the entire equipment. This is extremely beneficial for transporting and installing mud treatment equipment in special terrain environments such as mountainous areas and marshes. In mountainous areas, due to the rugged roads, the carrying capacity of transport vehicles is limited, and lightweight equipment can be more easily transported to the construction site. In marshes, lighter equipment can reduce the pressure on the ground and reduce the risk of sinking.

[0037] The weight of the whole mud treatment system is further reduced by using light material to make the frame and selecting relatively lighter screening components and pipeline materials. The frame uses aluminum alloy material to replace the traditional steel structure, and the weight can be reduced by about 30%-50%. The light screening components and flexible plastic pipelines also reduce the overall weight of the equipment to some extent, making the equipment more convenient to carry and move in special terrain environments, reducing the dependence on large lifting equipment and transportation tools, and reducing the construction cost and equipment transportation difficulty.

[0038] The common pump body for feeding and beating mud not only reduces the weight, but also simplifies the structure of the system. The connection pipelines, valves and control systems and other components between the pump bodies are reduced, and the complexity of the system is reduced. Due to the reduction in the number of pump bodies and the simplification of the system structure, the volume of the whole mud treatment system is smaller, and the layout can be more reasonable in the limited construction site space.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0048] Reference Figures 1-3 For the first embodiment of the present application, a light weight mud treatment system is proposed, comprising: a rack 1, the rack 1 has a liquid storage cavity 11; the screening element 2 is arranged on the rack 1, and the slurry enters the liquid storage cavity 11 from the screening element 2; the pump body 3 is arranged in the liquid storage cavity 11; the first pipeline 4 has an inlet 41, a first outlet 42 and a second outlet 43, the inlet 41 is communicated with the pump body 3, the first outlet 42 is communicated with the screening element 2, and the second outlet 43 is used for liquid outlet.

[0049] In this embodiment, in order to solve the problem of large volume and heavy weight of the conventional mud treatment equipment in the related art, which is not easy to use in special terrain environment, the slurry supply and beating share a pump body 3, the number of pump bodies 3 of the entire equipment is reduced, and the purpose of lightweight equipment is achieved. The rack 1 is in the shape of a cuboid, and has a liquid storage cavity 11 inside. The bottom of the liquid storage cavity 11 is designed with a certain slope to facilitate the flow and concentration of slurry in the cavity. The screening member 2 has a screen structure, and the screen holes can effectively remove impurity particles of different particle sizes in the mud, and the slurry can flow into the liquid storage cavity 11 from the screening member 2. The pump body 3 is placed at the lowest part of the bottom of the liquid storage cavity 11, and is fixed by a fixed support to prevent displacement during operation. The pump body 3 is a centrifugal pump with high lift, large flow and light weight, and is made of a composite structure of corrosion-resistant engineering plastic and metal, which reduces the weight while ensuring the performance. The first inlet 41 of the first pipeline 4 is tightly connected to the outlet of the pump body 3. The first outlet 42 of the first pipeline 4 leads to the screening member 2, which can perform secondary screening on the slurry in the liquid storage cavity 11. The second outlet 43 is connected to the subsequent mud conveying pipeline or mud storage container for outputting the treated qualified mud.

[0050] The original mud is conveyed to the upper part of the screening member 2 by an external conveying device, and the mud enters the liquid storage cavity 11 under the action of gravity through the screening member 2. The larger impurity particles are intercepted by the screen and accumulated on the screen, and the slurry is sprayed onto the screen again through the first outlet 42 of the first pipeline 4 for secondary treatment. The screened mud flows into the liquid storage cavity 11, and the pump body 3 is started to pump the mud in the liquid storage cavity 11. The mud is conveyed to the construction area or the next mud treatment process through the second outlet 43 to realize the slurry supply function. Since the slurry supply and beating share a pump body 3, the number of pump bodies 3 in the equipment is reduced, thereby reducing the weight and volume of the entire mud treatment system.

[0051] By sharing a pump body 3 for slurry supply and beating, at least one pump body 3 is reduced compared to the traditional mud treatment system which separately sets a slurry supply pump and a beating pump. After reducing one pump body 3, the weight of this part is directly reduced, and the weight of the entire equipment is significantly reduced. This is extremely beneficial for transporting and installing mud treatment equipment in special terrain environments such as mountainous areas and marshes. In mountainous areas, due to the rugged roads, the carrying capacity of the transport vehicles is limited, and lightweight equipment can be more easily transported to the construction site; in marshes, lighter equipment can reduce the pressure on the ground and reduce the risk of sinking.

[0052] The entire mud treatment system is further lightened by using light materials to make the frame 1 and by selecting relatively light screening members 2 and pipeline materials. The frame 1 is made of aluminum alloy material instead of traditional steel structure, and the weight can be reduced by about 30%-50%. The light screening members 2 and flexible plastic pipelines also reduce the overall weight of the equipment to some extent, making the equipment more convenient to carry and move in special terrain environments, reducing the dependence on large lifting equipment and transportation tools, and reducing the construction cost and equipment transportation difficulty.

[0053] The common pump body 3 for feeding and beating mud not only lightens the weight, but also simplifies the structure of the system. The connection pipelines, valves and control systems and other components between the pump bodies 3 are reduced, and the complexity of the system is reduced. Due to the reduction in the number of pump bodies 3 and the simplification of the system structure, the volume of the entire mud treatment system is smaller, and the layout can be more reasonable in the limited construction site space.

[0054] Further, the first switch 5 is arranged on the first pipeline 4, and the first switch 5 is used to open or close the first outlet 42. The second switch 6 is arranged on the first pipeline 4, and the second switch 6 is used to open or close the second outlet 43.

[0055] In this embodiment, the first switch 5 is installed on the first pipeline 4 near the first outlet 42 leading to the screening member 2, and the second switch 6 is installed at the second outlet 43 of the first pipeline 4. Before the mud treatment system is started, the first switch 5 and the second switch 6 are both in the closed state. The operator first checks the connection of the entire system, the lubrication of the pump body 3 and whether the screening member 2 is clean and other preparations.

[0056] When starting to treat mud, the pump body 3 is started, and the first switch 5 is opened and the second switch 6 is closed. At this time, the pump body 3 will pump out the mud in the storage cavity 11 and deliver it to the screening member 2 through the first outlet 42 of the first pipeline 4. This part of the circulating mud plays a secondary screening role. When the mud has been circulated and screened for a period of time and its performance meets the construction requirements, the first switch 5 is closed and the second switch 6 is opened. The mud pumped out by the pump body 3 will be delivered to the construction area or the subsequent mud storage container through the second outlet 43 of the first pipeline 4.

[0057] The first switch 5 and the second switch 6 are arranged to enable flexible switching between the mud supplying function and the mud beating function. The operator can control the flow direction of the mud according to the actual processing condition and construction requirement of the mud. When the mud is urgently needed for construction, the mud supplying mode can be quickly switched to by opening the second switch 6 and closing the first switch 5, so that the processed mud can be timely delivered out. The switching function improves the adaptability and practicability of the mud processing system, and can meet the mud processing and supply requirements under different working conditions. Since the flow direction of the mud can be controlled, the efficiency of the entire mud processing system is improved. The mud can be processed and delivered according to the optimized process, the time required for processing each batch of mud is reduced, the processing amount of the mud per unit time is improved, and the engineering progress can be significantly accelerated in large-scale foundation engineering construction.

[0058] With reference to Figure 4 Further, the rack 1 has a discharging channel 12, the first mounting frame 21 is movably arranged on the rack 1, and the first mounting frame 21 has a mounting space 22; the first screen 23 is arranged at both ends of the mounting space 22, the slurry enters the liquid storage cavity 11 through the screening member 2, and the impurities enter the discharging channel 12 through the first screen 23; the elastic member 24 has a plurality of elastic members, one end of each elastic member is arranged on the rack 1, and the other end is arranged on the first mounting frame 21, the elastic member 24 is used to provide a restoring force for the first mounting frame 21; the vibrating member 25 is arranged on the first mounting frame 21, and the vibrating member 25 is used to drive the first screen 23 to vibrate.

[0059] In this embodiment, the discharging channel 12 is designed to be inclined on one side of the rack 1, the discharging channel 12 is arranged to be inclined to the horizontal plane, and the inner wall of the discharging channel 12 is paved with smooth stainless steel plates to reduce the resistance when the impurities fall. The first mounting frame 21 is made of aluminum alloy, which has a relatively light weight and good strength. The first mounting frame 21 is uniformly distributed with elastic members 24 on the outer side, and the elastic members 24 are high-strength springs. One end of the spring is connected through a fixing seat welded on the rack 1, and the other end is connected to a connecting lug on the outer side of the first mounting frame 21.

[0060] The first screen 23 is made of stainless steel screen structure, which can effectively filter impurities of different particle sizes. The two ends of the first screen 23 are fixed in the mounting space 22 of the first mounting frame 21 by bolts, which ensures firm installation and inclined arrangement, so that solid impurities can slide into the discharging channel 12. The vibrating member 25 is a vibrating motor. Before the mud treatment system starts to operate, the elastic member 24 makes the first mounting frame 21 in the initial position, and the first screen 23 remains stable. At this time, the vibrating member 25 is in a stopped state. When the mud flows into the screening member 2 from the top, the vibrating member 25 is started, and the vibrating motor starts to vibrate. This vibration is transmitted to the first screen 23 through the first mounting frame 21, so that the first screen 23 generates up-down and left-right compound vibration. Under the action of vibration, the solid impurity particles in the mud begin to separate from the mud and move downward to the screen, and finally fall into the discharging channel 12.

[0061] The vibrating member 25 drives the first screen 23 to vibrate, so that the mud is in a constant state of movement on the screen. This vibration can effectively prevent the solid particles in the mud from blocking the screen holes, and improves the screening efficiency. The setting of the elastic member 24 provides a good buffer protection mechanism for the screening member 2. When a larger impact is encountered, such as a large rock fragment mixed in the mud hitting the screen, the elastic member 24 can absorb and disperse the impact force, avoiding damage to the first screen 23 and the rack 1 due to sudden impact. This greatly prolongs the service life of the screening member 2 and the rack 1, reduces the frequency of equipment maintenance and replacement, and reduces engineering costs.

[0062] Further, the second mounting frame 26 is arranged in the mounting space 22; the second screen 27 is arranged at the two ends of the second mounting frame 26 correspondingly, and the second screen 27 is located above the first screen 23. The slurry enters the first screen 23 from the second screen 27, and the impurities enter the discharging channel 12 from the second screen 27.

[0063] In this embodiment, the second mounting frame 26 is vertically mounted above the first screen 23 in the mounting space 22 formed by the first mounting frame 21, and the second mounting frame 26 is fixedly connected with the first mounting frame 21 to ensure stable structure. The second screen 27 is made of high-strength stainless steel wire woven screen. The two ends of the second screen 27 are tightly fixed on the second mounting frame 26 by bolts, and the slurry can uniformly enter the first screen 23 from the second screen 27 for further screening.

[0064] When the mud flows from the top of the screening member 2, it first contacts the second screen 27. Since the second screen 27 has a larger aperture, it can quickly intercept large-particle impurities in the mud. These impurities fall directly through the second screen 27 into the discharging channel 12 under the action of gravity and the flow of the mud, and slide into the impurity collection box along the discharging channel 12. The mud that has been preliminarily screened by the second screen 27 continues to flow downward and enters the first screen 23.

[0065] The combination of the second screen 27 and the first screen 23 forms a multi-stage filtering system. This multi-stage filtering can remove impurities in the slurry more finely, and can significantly improve the purity of the slurry compared to single-stage screen separation. The design of the second screen 27 above the first screen 23 conforms to the characteristics of the particle size distribution of impurities in the slurry. Large-particle impurities are first intercepted by the second screen 27 with a larger pore size, avoiding the clogging and wear of the first screen 23 by large-particle impurities, and prolonging the service life of the first screen 23. At the same time, it also makes the entire screening process more smooth, and the flow resistance of the slurry on the screen is smaller, further improving the screening efficiency.

[0066] Further, the baffle 7 is adjustably arranged on the second mounting frame 26, and the impurities are retained on the second screen 27 by the baffle 7.

[0067] In this embodiment, the baffle 7 is made of stainless steel and has the shape of a rectangular thin plate. On the inner side of the second mounting frame 26, a row of equidistant screw holes are arranged along the height direction. The two ends of the baffle 7 are connected to the second mounting frame 26 by bolts. By fixing the bolts in screw holes at different heights, the height of the baffle 7 can be adjusted.

[0068] When the slurry flows from above into the screening device 2, it first passes through the second screen 27. Under the action of the vibrating member 25, the impurities in the slurry begin to move downward. Due to the presence of the baffle 7, the impurities are blocked by the baffle 7 and cannot directly fall into the discharge channel 12, but are retained in the space between the baffle 7 above the second screen 27 and the second screen 27. To avoid the impurities entering the discharge channel 12 being too wet, when the water in the impurities continuously flows into the first screen 23, the water content of the impurities on the second screen 27 is less. By lowering the baffle 7 or removing the baffle 7, the impurities can be directly vibrated down by the vibrating member 25 after the second screen 27 is vibrated, without the need for manual cleaning of the impurities.

[0069] Since the baffle 7 concentrates the impurities in a specific space above the second screen 27, when the impurities need to be cleaned, the operator only needs to simply adjust the height of the baffle 7 or remove the baffle 7 to conveniently clean out the impurities, without the need for complex disassembly or flushing operations on the entire screen structure. This greatly reduces the difficulty and workload of impurity cleaning and reduces the equipment downtime.

[0070] Further, the spraying member 8 has a plurality of spraying members 8 arranged on the rack 1, and the spraying member 8 is used to clean the first screen 23 and the second screen 27.

[0071] In this embodiment, the spray member 8 is selected from a spray head made of stainless steel, each spray head having a plurality of small spray holes to improve the cleaning effect. The spray member 8 is installed at an angle towards the top of the first screen 23 and the second screen 27. After the mud treatment system runs for a period of time, impurities will gradually accumulate on the first screen 23 and the second screen 27, affecting the screening efficiency. At this time, the spray member 8 is started to spray water onto the screen through the spray member 8. The arrangement of the spray member 8 can comprehensively and deeply clean the first screen 23 and the second screen 27. The small impurity particles attached to the screen are washed away, effectively restoring the screening capacity of the screen.

[0072] Further, the stirring member 9 is rotatably arranged in the storage cavity 11, and the stirring member 9 is located below the storage cavity 11.

[0073] In this embodiment, the stirring member 9 is a propeller stirrer made of stainless steel. The blade is in the shape of a spiral, which has high stirring efficiency. When the mud flows into the storage cavity 11, the driving motor is started, and the propeller stirrer starts to rotate under the action of the stirring shaft. The stirrer rotates at a certain speed and produces strong stirring action below the storage cavity 11. It can turn the mud at the bottom of the storage cavity 11 upwards, so that the solid particles in the mud are always in a suspended state, preventing them from settling at the bottom of the storage cavity 11.

[0074] The rotation of the stirring member 9 can effectively break the settling trend of the solid particles in the mud, keeping the mud in a uniform mixed state in the storage cavity 11 at all times. Since the stirring member 9 prevents the mud from settling, it reduces the possibility of solid particles accumulating at the bottom of the storage cavity 11 and entering the slurry supply pipeline. Without stirring and anti-settling, the particles deposited at the bottom may be sucked into the pipeline during the slurry supply process, gradually accumulating to cause pipeline blockage. However, the system uniformly disperses the particles through stirring, ensuring that the mud entering the pipeline is uniformly mixed, reducing the risk of pipeline blockage and ensuring the continuity of slurry supply.

[0075] Further, the float switch 10 is located in the storage cavity 11; one end of the second pipeline 110 communicates with the float switch 10, and the other end extends out of the storage cavity 11.

[0076] In this embodiment, the float switch 10 is selected from a liquid level controller, which has good corrosion resistance and reliability. The float can freely float when the mud level rises. One end of the second pipeline 110 is fixed at the outlet of the float switch 10, and the other end penetrates the wall of the storage cavity 11 and extends outside the storage cavity 11.

[0077] When the mud liquid level in the storage cavity 11 gradually rises, the float ball of the float ball switch 10 rises with it. When the liquid level reaches the set warning height, the contacts inside the float ball switch 10 are closed, triggering a signal. At this time, the mud starts to flow out through the second pipeline 110 under the action of the pressure difference. With the outflow of the mud, the liquid level in the storage cavity 11 gradually decreases, and when the liquid level is lower than the warning height by a certain degree, the contacts of the float ball switch 10 are disconnected, and the mud stops overflowing through the second pipeline 110.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
