[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] like Figures 1 to 6 As shown, the movable engineering mud drying and separation equipment 100 of the embodiment of the present invention includes a feeding module 1, an aggregate grading module 2, a mud flocculation and concentration module 3, a mud water drying module 4 and a mobile module 5. The feeding module 1 is used to transport mud, the aggregate grading module 2 is connected to the feeding module 1 to receive the mud transported by the feeding module 1, and the aggregate grading module 2 is used to grade and separate the aggregate in the mud to form a mud-water mixture. The mud flocculation and concentration module 3 is connected to the aggregate grading module 2 to receive the mud-water mixture discharged by the aggregate grading module 2, and the mud flocculation and concentration module 3 is used to flocculate and concentrate the mud-water mixture to separate part of the water in the mud-water mixture and obtain concentrated mud. The mud water drying module 4 is connected to the mud flocculation and concentration module 3 to receive the concentrated mud discharged by the mud flocculation and concentration module 3, and the mud water drying module 4 is used to dry and dehydrate the concentrated mud and form a dried mud cake. The mobile module 5 is connected to the feeding module 1, the aggregate classification module 2, the mud flocculation and concentration module 3 and the mud and water drying module 4 respectively.

[0026] When the movable engineering mud drying and separation equipment 100 of the embodiment of the present invention is in use, the engineering mud is first transported to the loading module 1 of the movable engineering mud drying and separation equipment 100. The main function of this module is to receive and transport the mud to ensure that the mud can smoothly enter the subsequent processing module. The mud transported by the loading module 1 is then sent to the aggregate classification module 2, which is responsible for classifying and separating the solid aggregates in the mud. The separated aggregates can be recycled, and the remaining mud-water mixture is sent to the next module. Next, the mud-water mixture enters the mud flocculation and concentration module 3, in which the fine particles in the mud-water mixture are condensed into larger flocs by adding flocculants, which is convenient for further separation. Then, a concentration treatment is carried out to separate part of the water in the mud-water mixture, thereby forming a concentrated mud. The concentrated mud is then sent to the mud-water drying module 4, the purpose of which is to dry and dehydrate the concentrated mud, remove the water therein, and finally form a dried mud cake. The water content of the dried mud cake is greatly reduced, which is convenient for storage and transportation. The mobile module 5 of the entire processing equipment ensures that the equipment can be flexibly moved to different construction sites, thereby improving the applicability and convenience of the equipment.

[0027] The movable engineering mud drying and separation equipment 100 of the embodiment of the present invention reduces the moisture content by drying the mud, thereby reducing the transportation volume, improving transportation efficiency, and reducing transportation costs. Reducing the water content of the mud can effectively reduce spillage during transportation, reduce dust and noise pollution, and have a positive impact on the urban environment. Since the equipment is mobile, it can adapt to construction sites with limited space and meet the needs of different projects. The movable equipment reduces the demand for fixed facilities, saves the construction cost of supporting facilities, and reduces the cost of the entire engineering mud treatment. The centralized module design makes the entire processing flow more compact and efficient, and speeds up the processing speed. The dried mud cake can be used as a raw material for other building materials, realizing the recycling of resources. By reducing the water content of the mud, the muddy situation on the construction site is reduced, which helps to improve construction safety.

[0028] In some embodiments, the mud feeding module 1 includes a suction pump 101 , a buoy 102 and a feeding pipeline 103 . The suction pump 101 is disposed on the buoy 102 and is connected to the inlet of the feeding pipeline 103 . The outlet of the feeding pipeline 103 is connected to the aggregate grading module 2 .

[0029] The suction pump 101 is one of the core components of the feeding module 1. Its main function is to extract the mud from the ground or the mud pool and transport it to the feeding pipeline 103 through stirring and suction. The suction pump 101 usually has strong suction and wear resistance, and can handle mud containing a certain proportion of solid particles. The buoy 102 is a component combined with the suction pump 101. Its main function is to keep the suction pump 101 floating on the mud surface and ensure that the suction pump 101 can evenly extract the mud from the mud surface.

[0030] Specifically, the buoy 102 is placed on the surface of the mud, and the position of the buoy 102 is adjusted to adapt to the mud pool of different depths. The suction pump 101 is started, and the suction pump 101 starts to work under the support of the buoy 102 to extract mud from the mud pool. The mud is sucked into the feeding pipeline 103 through the suction pump 101 and is transported to the aggregate grading module 2 along the pipeline. The outlet of the feeding pipeline 103 is connected to the aggregate grading module 2. After the mud enters the aggregate grading module 2, the separation mechanism in the module separates the aggregates in the mud, and at the same time forms a mud-water mixture, which enters the subsequent flocculation concentration and drying treatment links.

[0031] The combination of the suction pump 101 and the buoy 102 can extract mud from the mud pool quickly and efficiently, reducing the investment of manpower and time. The design of the buoy 102 allows the feeding module 1 to adapt to mud pools of different depths, increasing the scope of application of the equipment. The design of the suction pump 101 and the feeding pipeline 103 helps to reduce leakage and overflow of mud during transportation, reducing the impact on the environment.

[0032] In some embodiments, the aggregate classification module 2 includes a vibrating screen 201 and a cyclone 202. The vibrating screen 201 has a mud inlet 2011, an aggregate outlet 2012 and a mud-water mixture outlet. The mud inlet 2011 is connected to the outlet of the feeding pipeline 103. The vibrating screen 201 is used to screen the aggregate in the mud and discharge the screened aggregate through the aggregate outlet 2012. The cyclone 202 is connected to the mud-water mixture outlet and the mud-water drying module 4 respectively. The cyclone 202 is used to separate the fine sand in the screened mud-water mixture and transport the separated mud-water mixture to the mud-water drying module 4.

[0033] The mud inlet 2011 is connected to the outlet of the feeding pipeline 103 to receive the mud from the feeding module 1. The mud passes through the vibrating screen 201, and the larger aggregates are retained on the screen due to the size of the screen holes, while the smaller particles and water pass through the screen holes. The separated aggregates are discharged through the aggregate outlet 2012 and can be further utilized or processed as needed. The mud-water mixture separated by the vibrating screen 201 is discharged through the mud-water mixture outlet and enters the next stage of processing. The cyclone 202 is another grading device, which is connected to the mud-water mixture outlet of the vibrating screen 201 and the mud-water drying module 4. The working principle of the cyclone 202 is to use centrifugal force to separate fine sand and other finer particles: the cyclone 202 receives the mud-water mixture from the vibrating screen 201, generates centrifugal force through high-speed rotation, and separates the heavier fine sand particles from the mixture. The mud-water mixture after the fine sand is separated is transported to the mud-water drying module 4 for subsequent drying and dehydration treatment.

[0034] The combination of the vibrating screen 201 and the cyclone 202 provides an efficient multi-stage separation capability, which can process particles of different sizes. By separating particles of different sizes, resources such as aggregates and fine sand can be recycled to maximize the utilization of resources. By initially separating aggregates and fine sand, the load of the subsequent mud and water drying module 4 can be reduced, and the processing efficiency and stability of the entire system can be improved.

[0035] Optionally, the vibrating screen 201 includes a primary screen 2013 and a secondary screen 2014 , the primary screen 2013 is located above the secondary screen 2014 , and the sieve holes of the primary screen 2013 are larger than the sieve holes of the secondary screen 2014 .

[0036] The double screening of the primary screen 2013 and the secondary screen 2014 can more effectively separate aggregates of different sizes and improve the overall screening efficiency. The primary screen 2013 first screens out larger aggregates, reducing the blockage of the secondary screen 2014 by fine particles, and improving the service life and working efficiency of the secondary screen 2014. The combined use of double screening and cyclone 202 can significantly improve the processing capacity of the entire aggregate classification module 2 and meet the needs of large-scale mud processing.

[0037] In some embodiments, the aggregate classification module 2 includes a spraying component, which is disposed on the vibrating screen 201 , and is used to spray clean water onto each of the primary screen 2013 and the secondary screen 2014 .

[0038] Clean water can wash the aggregate on the screen, help remove the dirt and other attachments on the surface of the aggregate, and improve the cleanliness of the aggregate. By spraying clean water, the adhesion of fine particles and mud on the screen can be reduced, thereby improving the screening efficiency and the separation effect of aggregates. Clean water spraying also helps prevent the screen from being blocked by fine particles in the mud and keeps the screen unobstructed.

[0039] In some embodiments, the aggregate grading module 2 further includes a dewatering screen 203 . The mud at the top of the cyclone 202 enters the mud-water drying module 4 , and the fine sand at the bottom of the cyclone 202 enters the dewatering screen 203 . The dewatering screen 203 is used to dewater the fine sand discharged from the cyclone 202 .

[0040] The top of the cyclone 202 receives the mud-water mixture from the mud inlet 2011, and separates the fine sand in the mud by centrifugal force. The separated fine sand enters the bottom of the cyclone 202. The fine sand at the bottom of the cyclone 202 is dehydrated by the dewatering screen 203. The working principle of the dewatering screen 203 is similar to that of the vibrating screen 201, and the water in the fine sand is removed by screening and dehydration. The dehydrated fine sand is discharged through the outlet of the dewatering screen 203, and relatively dry fine sand can be obtained, which can be used for building materials or other industrial purposes. The mud at the top of the cyclone 202 is sent to the mud-water drying module 4 for further drying treatment.

[0041] In some embodiments, the mud flocculation and concentration module 3 includes a primary mud tank 301, a secondary clean water tank 302, and a tertiary mud tank 303. The primary mud tank 301 is connected to the cyclone 202 to receive the mud-water mixture separated by the cyclone 202. The primary mud tank 301 is used to mix the mud-water mixture with the flocculant to achieve preliminary separation of mud and water. The clean water separated by the primary mud tank 301 overflows into the secondary clean water tank 302, and the mud separated by the primary mud tank 301 is transported to the tertiary mud tank 303. The tertiary mud tank 303 is used to mix the mud with the curing agent to form concentrated mud.

[0042] In some embodiments, the movable engineering mud drying and separation equipment 100 of the embodiment of the present invention also includes a clean water circulation module 6, which is connected to the spray component and the secondary clean water tank 302 respectively. The clean water circulation module 6 is used to receive the clean water in the secondary clean water tank 302 and supply water to the spray component.

[0043] The clean water circulation module 6 is connected to the spray component through a pipeline to provide the spray component with the required water source for washing the aggregate on the vibrating screen 201. The clean water circulation module 6 is also connected to the secondary clean water tank 302, receiving the treated clean water from the secondary clean water tank 302, and recycling it again after purification. Through the clean water circulation module 6, the clean water generated during the treatment process can be effectively recovered and reused, reducing the consumption of fresh water resources. The recycled clean water is purified to ensure that the spray component always has a clean water source, thereby improving the cleaning effect of the aggregate. The use of the clean water circulation module 6 reduces the amount of wastewater discharged and helps to reduce the impact on the environment.

[0044] In some embodiments, the movable engineering mud drying and separation equipment 100 of the embodiment of the present invention includes a liquid agent box 7 and a powder agent box 8, both of which are arranged on the aggregate classification module 2. The liquid agent box 7 is connected to the primary mud box 301, and is used to add flocculants to the primary mud box 301, and the powder agent box 8 is connected to the tertiary mud box 303, and is used to add curing agent to the tertiary mud box 303.

[0045] The flocculant in the liquid agent tank 7 is transported to the first-level mud tank 301 through a pipeline and mixed with the mud. The flocculant plays a role in the mud, prompting fine particles to condense into larger flocs. The use of flocculants can significantly improve the separation efficiency of suspended solids in the mud and reduce the load of subsequent processing links. The coagulant curing agent in the powder agent tank 8 is transported to the third-level mud tank 303 through a pipeline and mixed with the mud. The coagulant curing agent plays a role in the mud, further solidifies the flocs formed by the flocculant, and forms a stable structure. The solidified mud is easier to dry, which can improve the drying efficiency and reduce the drying time and energy consumption.

[0046] In some embodiments, the movable engineering mud drying and separation equipment 100 of the embodiment of the present invention also includes an integrated control module 9, which is controlled and connected to the feeding module 1, the aggregate grading module 2, the mud flocculation and concentration module 3, the mud and water drying module 4 and the moving module 5.

[0047] The integrated control module 9 includes a central processing unit (CPU), an input / output (I / O) interface, sensors, actuators and a corresponding software control system.

[0048] The control module 9 can monitor the operating status of the feeding module 1, including the operation of the agitation pump 101, the conveying speed and amount of the mud, etc. The control module 9 monitors the operation of the vibrating screen 201 and the cyclone 202, and adjusts the screening parameters and the rotation speed of the cyclone 202 to ensure effective aggregate grading. The control module 9 manages the addition of flocculants and coagulants, monitors the flocculation and concentration process, and ensures the effective separation of water in the mud. The control module 9 monitors the operation of the drying module, including drying temperature, humidity control and drying efficiency. The control module 9 can control the movement of the entire equipment to ensure that the equipment can be quickly moved to different construction sites as needed. The integrated control module 9 monitors the operating status of each module in real time through sensors, including parameters such as current, pressure, temperature, and liquid level.

[0049] The control module 9 can automatically adjust the working parameters of each module, such as the speed of the pump, the frequency of screening, the drying temperature, etc., according to the preset program or the data detected by the sensor. If any abnormal situation is detected, such as equipment failure, parameters exceeding the preset range, etc., the control module 9 can trigger an alarm to notify the operator to take corresponding measures. The control module 9 can record and store key data in the processing process, such as processing volume, running time, energy consumption, etc., for process analysis and performance evaluation. The integrated control module 9 is usually equipped with a user interface that allows the operator to monitor the system status, adjust settings and perform operations.
