Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a mud processing device and a mud processing method. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present application and does not constitute prior art.

[0003] With the continuous acceleration of urbanization, mud is a common engineering construction derivative in the engineering construction industry. Mud is a mixture of water and various fine particles of clay and sand. The natural sedimentation rate of mud is very slow.

[0004] At present, there are three general methods commonly used in the industry for mud purification: the first one is more environmentally friendly and is natural sedimentation: digging pits, piling dams, collecting on-site or off-site, and drying naturally. However, this method occupies a large area. For construction sites, deliberate digging of pits will affect normal construction, and digging pits in off-site places has the risk of being unattended. In addition, the natural sedimentation and drying cycle is long, and land reclamation is difficult, which damages the ecology and is unsafe. It is also difficult to borrow land in cities. The second method is direct discharge, usually transported overseas for discharge, which is costly. Therefore, driven by interests, it is very likely to cause illegal discharge and dumping, causing environmental or water pollution. The third method is to use a centrifugal device to centrifugally dehydrate the mud, but such devices are usually inefficient, and the water inside the device cannot be quickly discharged. For the above phenomenon, the prior art provides many solutions, such as a sludge dewatering device disclosed in GB1215911, which includes a filter cartridge rotatably installed around a rotation axis and a conveyor coaxial with a roller. The slurry inlet is located at the inlet end of the drum; the device is designed with a conveyor belt that rotates independently of the filter drum to allow better control for changing the flow of slurry, but the device still has problems with centrifugal efficiency.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0006] The object of the present invention is to provide a mud processing device and a mud processing method, which can dehydrate the mud on site with low energy consumption, ensure the mud dehydration rate through multi-stage dehydration treatment of the mud, and effectively monitor the mud concentration during the dehydration process.

[0007] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0008] The invention provides a device for treating mud. The mud treating device comprises two major component assemblies, namely a first base and a second base. The mud separated from the first base is transported to the second base through a first pump body for treatment.

[0009] The first base is connected to the first pump body through the first tube body, and the second base is also connected to the first pump body through the first tube body. The liquid inlet of the first pump body is connected to the first base through the first tube body to receive mud, and the liquid outlet of the first pump body is connected to the first tube body and the second base to transport the mud to the second base.

[0010] The specific scheme of the second substrate is: the interior of the second substrate is hollow, a separation tube body is vertically arranged in the middle of the second substrate, the bottom end of the separation tube body extends to the outer bottom of the second substrate and is connected to the first pump body through the first tube body, that is, the separation tube body on the side of the feed chamber is connected to the first pump body through the first tube body, the end of the separation tube body extending to the outer bottom of the second substrate is connected with a solenoid valve, and the space between the separation tube body and the solenoid valve at the bottom of the second substrate constitutes a feed chamber, the solenoid valve is controlled by an external industrial computer, a discharge shell is provided on the upper part of the second substrate, a first motor is provided on the upper part of the discharge shell, a stirring shaft coaxial with the separation tube body is provided inside the separation tube body, stirring blades are spirally arranged on the stirring shaft, the stirring shaft is coaxially connected to the output shaft of the first motor, mesh holes are provided on the tube wall of the separation tube body located in the second substrate, the second tube body is connected to the bottom of the second substrate, and the outlet end of the second tube body is connected to the solenoid valve, which is also controlled by the industrial computer.

[0011] The solution for designing the second base body of the present invention adopts a vertically arranged stirring shaft in conjunction with a separation tube body to stir, separate and dehydrate the mud. The first pump body extracts the mud in the first base body in batches and transports it to the feed chamber, thereby ensuring the effect of single-time mud treatment. During the operation of the stirring shaft, the solenoid valve on the second tube body is opened, so that the mud sent to the feed chamber continuously moves upward. During the upward movement, the water in the mud can be discharged through the mesh holes on the separation tube body. The discharged water is collected in the space between the second base body and the separation tube body and discharged through the second tube body. The concentration of the internally treated mud is monitored by observing and monitoring the water discharge speed and liquid quality of the second tube body. In this process, the possibility of particles and lumps in the mud moving upward due to the influence of gravity is reduced, and gravity is used to control the mud. The slurry is separated to achieve energy-saving effect, and the problem of interference or damage to the rotation of the stirring shaft by stones and mud blocks in the mud is effectively solved. On this basis, the mud is driven to rotate by the rotation of the stirring shaft and the stirring blades, and the water in the mud is removed by centrifugal action. Similarly, as the water in the mud is removed, the agglomerated mud blocks move down into the feed chamber under the action of gravity, and in the process of the downward movement of the agglomerated mud blocks, the mud with a higher water content at the bottom can be squeezed to move upward, ensuring that the stirring shaft and the stirring blades continue to process the mud with a higher water content, thereby avoiding the reduction in the efficiency of the mud filtering centrifugal treatment and reducing the increase in energy consumption due to excessive mud resistance of the stirring shaft and the stirring blades in the later stage of stirring. After completing a single batch of processing, the obtained mud blocks are discharged by opening the solenoid valve below the feed chamber.

[0012] According to one embodiment of the present invention, the discharge housing has a hollow connection housing, the bottom of the connection housing is connected to the separation tube body, and a hollow guide housing is inclined on the side of the connection housing, and the guide housing is connected to the hollow interior of the connection housing. The design of the discharge housing is used to realize the arrangement of a discharge channel on the upper part of the separation tube body. In the process of inputting mud into the interior of the feed chamber, there may be a situation where excessive mud is input, which will cause the first motor connected to the stirring shaft to increase power consumption and excessive pressure inside the separation tube body. The connection housing of the discharge housing is used to provide a accommodating space for accommodating excess mud and accommodating mud that may be thrown into the connection housing by centrifugal force during the centrifugal process. After the water in the mud is removed, the mud in the connection housing flows back to the separation tube body for further dehydration. Considering the potential risks of excessive mud entering the interior of the connection housing, the guide housing is designed to discharge the excess mud, specifically to the first substrate or other auxiliary parts, so that the mud can enter the separation tube body again for separation.

[0013] According to one embodiment of the present invention, a bearing is coaxially arranged on the inner wall of the separation tube body in the second base body, and the bearing is connected to the stirring shaft through a connecting rod. The connecting rod and the bearing are designed to solve the problem that the stirring shaft may shake during rotation, thereby ensuring that the stirring blades will not scratch the separation tube body during high-speed rotation of the stirring shaft, and reducing the possibility of increased power consumption of the first motor. The connecting rod has a cutting effect on the upwardly displaced mud while ensuring the stable connection between the bearing and the stirring shaft. The connecting rod can rotate with the stirring shaft and can cut and scatter the mud, destroying its original mud and liquid distribution state and promoting the separation of water in the mud and liquid.

[0014] According to one embodiment of the present invention, the end of the stirring shaft located in the direction of the feed chamber is abutted against a support base, the side of the support base is connected to the inner ring of the bearing through a connecting rod, and the outer ring of the bearing is fixedly connected to the inner wall of the separation tube body. The shaking of the stirring shaft during rotation is reduced by abutting the end of the stirring shaft against the support base, that is, limiting the range of the axis deviation during the rotation of the two ends of the stirring shaft, so that the stirring blades can be prevented from scratching the separation tube body during high-speed rotation with the stirring shaft, and the possibility of increased power consumption of the first motor can be reduced. The connecting rod has a cutting effect on the upwardly displaced mud while ensuring the stable connection between the bearing and the stirring shaft. The connecting rod can destroy the original mud-liquid distribution state of the upwardly moving mud and promote the separation of water in the mud-liquid.

[0015] According to one embodiment of the present invention, the supporting base is a rotating body structure, and the interior of the supporting base is hollow. The upper surface of the supporting base has an inner groove, which is adapted to the stirring shaft. A first through hole is provided on the groove surface of the inner groove. The lower surface of the supporting base has an inner groove corresponding to the upper surface and a first through hole. The diameter of the middle part of the supporting base is larger than the diameter of the two ends of the supporting base, so that the supporting base has two upper and lower inclined annular surfaces, and the upper and lower annular surfaces of the supporting base are respectively surrounded by swing components. Through the structural design of the supporting base, its external structure is formed into a "flying saucer" shape, which has a diversion effect on the mud flowing up and down along the outer surface of the supporting base, avoiding excessive concentration of mud around the end of the stirring shaft and causing excessive shaking. When the supporting base and the connecting rod rotate synchronously, the mud along its outer surface is prompted to flow in a spiral manner, which helps to remove water from the mud. In addition, the hollow design of the interior of the supporting base and the opening of the first through hole are used to avoid interference from mud or stones at the abutment between the end of the stirring shaft and the supporting base. Specifically, in the case where mud or stones appear between the stirring shaft and the supporting base, the mud or stones can enter the first through hole with the rotation, avoiding mud, stones, etc. interfering with the effective abutment between the stirring shaft and the supporting base.

[0016] According to one embodiment of the present invention, the swing assembly includes two connecting plates arranged parallel to each other, a swing rod capable of rotation is connected between the connecting plates, a swing plate is connected to the swing rod along the axis, the swing plate is bent, a spacing is provided between the two sides of the swing plate and the connecting plate, a spring is provided between one side or both sides of the swing plate and the connecting plate, and the spring is sleeved on the swing rod. The connecting plate is vertically connected to the annular surface of the supporting base. The swing assembly is designed to improve the pushing effect of the mud on the supporting base, and the swing blade on the swing assembly is used to expand the contact area with the mud, thereby expanding the pushing effect of the mud on the supporting base connected to the swing assembly, prompting the supporting base to produce a rotational motion, and synchronously driving the connecting rod connected to it to rotate, so as to divert the upward moving mud and destroy the original mud-liquid distribution state of the mud to promote the separation of water in the mud and liquid. In addition, a rotatable swing rod is provided on the swing assembly to enable the swing blade to swing with the impact of the mud, thereby avoiding deformation of the swing blade caused by excessive impact force of the mud, etc. After the swing blade is bent, its contact area with the mud is effectively ensured. Even when the swing blade is in contact with the outer surface of the supporting base, the bent end of the swing blade still has an area in contact with the mud. The swing speed of the swing blade is limited by designing a spring on the swing rod, that is, the first spring elastically supports the swing blade to reduce its rotational swinging speed.

[0017] According to one embodiment of the present invention, the first substrate is hollow and has a through top. A second filter plate that can swing is tilted inside the first substrate. The second filter plate divides the first substrate into a feed chamber and a filter chamber arranged up and down. The filter chamber is arranged below the second filter plate. The first tube body leads into the filter chamber. A mud discharge port is correspondingly provided on the first substrate wall at the tilted bottom of the second filter plate. A shaking motor equipped with the second filter plate is provided on the inner wall of the first substrate. The initial mud is subjected to primary treatment through the first substrate, specifically, the first substrate is separated by the second filter plate, so that large mud blocks, primary stones, steel bars, etc. in the mud fed into the first substrate can be separated and discharged through the mud discharge port for centralized treatment. The inside of the filter chamber is used to collect mud in preparation for secondary treatment.

[0018] According to one embodiment of the present invention, a feed chamber is arranged above the second filter plate, and a conveying assembly is arranged in the feed chamber, and the conveying assembly includes a driving wheel and a driven wheel rotatably connected to the first base body, and the axes of the driving wheel and the driven wheel have different horizontal heights, and the driving wheel is driven by a second motor arranged outside the first base body to rotate, and the driving wheel is arranged close to the mud discharge port, and the rotation direction of the driving wheel is arranged opposite to the discharge direction of the mud discharge port, and the mud is conveyed in the opposite direction of the mud discharge port through the conveying assembly, and during the conveying process, gravity and the impact of the continuously falling mud are used to cause the mesh conveyor belt on the conveying assembly to shake to make the liquid in the mud fall onto the second filter plate, so that stones, bricks, etc. in the mud are not retained, and the slope of the second filter plate and the shaking motor at its bottom are used to cause the retained mud blocks, bricks, etc. to be discharged from the mud discharge port for centralized treatment.

[0019] According to one embodiment of the present invention, a mesh conveyor belt is provided on the driving wheel and the driven wheel, and conveyor chains are symmetrically arranged on both sides of the mesh conveyor belt. The conveyor chain rotates synchronously with the mesh conveyor belt, and L-shaped push plates are arranged at intervals on the upper part of the mesh conveyor belt, and flexible plates are provided on the push plates. The present invention separates large objects in the mud, such as mud blocks, bricks, and steel bars, through the mesh conveyor belt on the conveyor belt assembly to prevent them from entering the secondary treatment process to interfere with the subsequent mud dehydration efficiency and damage the equipment. The push plate is arranged on the mesh conveyor belt to limit the displacement of large objects in the mud, that is, to prevent the large objects from sliding directly to the mud discharge port after the mud reaches the conveyor belt assembly. The push plate is used to push the large objects in the opposite direction of the mud discharge port, which helps to separate the mud on the upper part of these large objects, such as separating the mud from the surface of the brick. Such large objects fall into After the second filter plate is on, the mud on the surface of these objects is separated again due to the action of the shaking motor during the relative shaking process of these objects, and the push plate located on the adjacent surface of the second filter plate cooperates with the flexible push plate on its upper part to push these objects to move on the second filter plate, avoiding the accumulation of materials and the problem of excessive mud adhering to the materials discharged from the mud discharge port. At the same time, the method of arranging a flexible plate on the upper part of the push plate not only improves the restriction effect on large objects, but also prevents friction or jamming between the conveying component and the second filter plate, that is, the friction between the push plate and the second filter plate is avoided by the flexible mesh plate.

[0020] According to one embodiment of the present invention, a first filter plate is provided between the conveying assembly and the mud discharge port, the first filter plate is located in the feed chamber, and there is a gap between the bottom of the first filter plate and the second filter plate, so that the first filter plate further prevents the mud from being directly discharged.

[0021] The specific steps of the mud treatment method using the mud treatment device are as follows:

[0022] 1) Primary solid-liquid separation of mud through the first matrix;

[0023] 2) The first pump body is used to separate the solid and liquid of the first matrix to obtain slurry which is sent to the second matrix in batches;

[0024] 3) The second base body performs secondary solid-liquid separation on the slurry sent into the first pump body.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention performs multi-stage treatment on the mud, removes larger stones, mud blocks, bricks and even steel bar fragments in the mud during the primary treatment process, solves the problem of interference of such objects with the mud treatment process and damage to the equipment, dehydrates the mud generated at the construction site through multi-stage and batch solid-liquid separation with low energy consumption, and ensures the mud dehydration rate. The scheme designed by the present invention specifically utilizes gravity to separate the mud after the primary treatment to achieve energy-saving effects, and effectively solves the problem of interference or damage to the rotation of the stirring shaft by stones, mud blocks, etc. in the mud, and also avoids the filtering centrifugal treatment of the mud and reduces the increase in energy consumption of the stirring shaft and the stirring blades due to excessive mud resistance in the later stage of stirring. The concentration of the mud processed inside the monitoring equipment is realized by observing and monitoring the water discharge speed and liquid quality of the second pipe body.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention is further described in detail below in conjunction with specific implementations and drawings:

[0039] Embodiment 1:

[0040] The present invention provides a device for treating a large amount of mud at existing construction sites. Figure 1 As shown, the mud treatment device is composed of two major components, specifically a first matrix 10, which is used to perform primary treatment on the mud generated during construction, that is, to perform preliminary solid-liquid separation on the mud generated during construction, and quickly separate larger stones, mud blocks, bricks, and even steel bar debris in the mud, and the other component is a second matrix 30, which is used to perform deep treatment on the mud, remove the water in the mud, and reduce the water content in the mud blocks produced. The stones, mud blocks and other materials obtained by the preliminary solid-liquid separation of the first matrix 10 are collected and stacked together to ensure an orderly layout of the construction site. At the same time, the mud separated by the first matrix 10 is transported to the second matrix 30 through the first pump body 20 for treatment.

[0041] Attached Figure 1 The first base 10 is connected to the first pump body 20 through the first tube body 21, and the second base 30 is also connected to the first pump body 20 through the first tube body 21. The liquid inlet of the first pump body 20 is connected to the first base 10 through the first tube body 21 to receive mud, and the liquid outlet of the first pump body 20 is connected to the second base 30 through the first tube body 21 to transport the mud to the second base 30.

[0042] See attached Figure 2As shown in Figure 3, the specific scheme of the second base body 30 is as follows: the second base body 30 is hollow inside, a separation tube body 31 is vertically arranged in the middle of the second base body 30, the bottom end of the separation tube body 31 extends to the outer bottom of the second base body 30 and is connected to the first pump body 20 through the first tube body 21, that is, the separation tube body 31 on the side of the feed chamber 32 is connected to the first pump body 20 through the first tube body 21, the end of the separation tube body 31 extending to the outer bottom of the second base body 30 is connected to the electromagnetic valve, and the space between the separation tube body 31 at the bottom of the second base body 30 and the electromagnetic valve constitutes the feed chamber. 32, the solenoid valve is controlled by an external industrial computer, a discharge shell 50 is provided on the upper part of the second base 30, a first motor 40 is provided on the upper part of the discharge shell 50, a stirring shaft 42 coaxial with the separation tube body 31 is provided inside the separation tube body 31, stirring blades 41 are spirally arranged on the stirring shaft 42, the stirring shaft 42 is coaxially connected with the output shaft of the first motor 40, mesh holes are provided on the tube wall of the separation tube body 31 located in the second base 30, a second tube body 33 is connected to the bottom of the second base 30, and a solenoid valve is connected to the outlet end of the second tube body 33, which is also controlled by the industrial computer.

[0043] The design scheme of the second matrix 30 of the present invention adopts a vertically arranged stirring shaft 42 to cooperate with the separation tube body 31 to stir, separate and dehydrate the mud. The first pump body 20 extracts the mud in the first matrix 10 in batches and transports it to the feed chamber 32, thereby ensuring the effect of single-time mud treatment. During the operation of the stirring shaft 42, the solenoid valve on the second tube body 33 is opened, so that the mud sent to the feed chamber 32 continuously moves upward. During the upward movement, the water in the mud can be discharged through the mesh on the separation tube body 31. The discharged water is collected in the space between the second matrix 30 and the separation tube body 31 and discharged through the second tube body 33. The internal treatment mud concentration is monitored by observing and monitoring the water discharge speed and liquid quality of the second tube body 33. In this process, the possibility of particles and lumps in the mud moving upward due to gravity factors is reduced, which is beneficial to The mud is separated by gravity to achieve energy-saving effects, and the problem of stones, mud blocks, etc. in the mud interfering with or destroying the rotation of the stirring shaft 42 is effectively solved. On this basis, the mud is driven to rotate by the rotation of the stirring shaft 42 and the stirring blade 41, and the water in the mud is removed by centrifugal action. Similarly, as the water in the mud is removed, the agglomerated mud blocks move down into the feed chamber 32 under the action of gravity, and in the process of the downward movement of the agglomerated mud blocks, the mud with a higher water content at the bottom can be squeezed to move upward, ensuring that the stirring shaft 42 and the stirring blade 41 continue to process the mud with a higher water content, thereby avoiding the reduction in the efficiency of the mud filtration centrifugal treatment and reducing the increase in energy consumption of the stirring shaft 42 and the stirring blade 41 due to excessive mud resistance in the later stage of stirring. After completing a single batch of processing, the obtained mud blocks are discharged by opening the solenoid valve below the feed chamber 32.

[0044] The design of the feed chamber 32 in the present design can also solve the problem of residual mud and mud blocks. Specifically, after a single batch of mud is processed, when the subsequent mud enters the feed chamber 32, it can have a flushing effect on the feed chamber 32. If mud blocks or mud residues appear, they can be flushed for mud separation again. A backwash feed pipe port is also provided on the upper part of the second base 30 for backwashing the interior thereof. During the backwashing process, the solenoid valve connected to the feed chamber 32 is opened and the backwashing output water is transported to the first base 10 or other auxiliary parts to avoid environmental pollution. Similarly, during backwashing, the upper solenoid valve of the second tube 33 is opened, and the backwashing output water is transported to the first base 10 or other auxiliary parts. The present scheme solves the problem of residual mud and mud blocks through the above design.

[0045] If the mud block flows slowly toward the solenoid valve, the stirring shaft 42 is controlled to flip to provide a downward thrust to promote the location of the mud block.

[0046] See attached Figure 2 As shown in Figure 3, the discharge housing 50 has a hollow connection housing 51, the bottom of the connection housing 51 is connected to the separation tube body 31, and a hollow guide housing 52 is inclined at the side of the connection housing 51, and the guide housing 52 is connected to the hollow interior of the connection housing 51. The included angle between the guide housing 52 and the horizontal plane is a negative number, that is, the inclination direction of the guide housing 52 is downward, not upward. Through this design, the discharged mud blocks and the like can slide by gravity when discharged along the guide housing 52, thereby improving the discharge efficiency. In addition, when the stirring shaft 42 and the stirring blade 41 in the separation tube body 31 continuously drive the mud blocks to move upward, the mud blocks moving upward provide "thrust" to the mud blocks in the guide housing 52 to promote the discharge efficiency of the mud blocks in the guide housing 52.

[0047] The design of the discharge shell 50 is used to realize the arrangement of a discharge channel on the upper part of the separation tube body 31. In the process of inputting mud into the feed chamber 32, there may be an excessive amount of mud input, which will cause the power consumption of the first motor 40 connected to the stirring shaft 42 to increase and the internal pressure of the separation tube body 31 to be too high. The connecting shell 51 of the discharge shell 50 is used to provide a accommodating space for accommodating excess mud and accommodating mud that may be thrown into the connecting shell 51 by centrifugal force during the centrifugal process. After the water in the mud is removed, the mud in the connecting shell 51 flows back to the separation tube body 31 for further dehydration. In view of the possible hidden dangers of excessive mud entering the connecting shell 51, the guide shell 52 is designed to discharge excess mud, specifically to discharge it to the first substrate 10 or other auxiliary parts, so that the mud can enter the separation tube body 31 again for separation.

[0048] See attached Fig.10As shown, the other auxiliary component referred to in this case is an auxiliary box 70.

[0049] See attached Figure 3 , 5 As shown, the inner wall of the separation tube body 31 in the second base body 30 is coaxially provided with a bearing 60, and the bearing 60 is connected to the stirring shaft 42 through a connecting rod 61. The problem that the stirring shaft 42 may shake during the rotation process is solved by designing the connecting rod 61 and the bearing 60, ensuring that the stirring blade 41 will not scrape the separation tube body 31 during the high-speed rotation of the stirring shaft 42, and also reducing the possibility of increased power consumption of the first motor 40. The connecting rod 61 has a cutting effect on the upwardly displaced mud while ensuring the stable connection between the bearing 60 and the stirring shaft 42. The connecting rod 61 can rotate with the stirring shaft 42 and can cut and scatter the mud, destroying its original mud liquid distribution state and promoting the separation of water in the mud liquid. The connecting rod 61 in this embodiment is set at the middle section of the stirring shaft 42, so that the shaking problem of the upper and lower ends of the stirring shaft 42 can be avoided.

[0050] See attached Figure 7 , 8 As shown, the first substrate 10 is hollow inside and the upper part is through, and a second filter plate 17 capable of swinging is obliquely arranged inside the first substrate 10. The second filter plate 17 divides the inside of the first substrate 10 into a feed chamber and a filter chamber 18 arranged up and down. The filter chamber 18 is arranged below the second filter plate 17, and the first tube 21 passes into the filter chamber 18. A mud discharge port 15 is correspondingly provided on the wall of the first substrate 10 at the inclined bottom end of the second filter plate 17, and a shaking motor 16 equipped with the second filter plate 17 is provided on the inner wall of the first substrate 10. The initial mud is treated at the first level by the first substrate 10, specifically, the second filter plate 17 is used to separate the first substrate 10, so that large mud blocks, primary stones, steel bars, etc. in the mud fed into the first substrate 10 can be separated and discharged through the mud discharge port 15 for centralized treatment, and the inside of the filter chamber 18 is used to collect mud in preparation for secondary treatment.

[0051] A feed chamber is arranged above the second filter plate 17, and a conveying assembly 11 is arranged in the feed chamber. The conveying assembly 11 includes a driving wheel and a driven wheel rotatably connected to the first base body 10. The axes of the driving wheel and the driven wheel have different horizontal heights. The driving wheel is driven to rotate by a second motor 12 arranged outside the first base body 10. The driving wheel is arranged close to the mud discharge port 15, and the rotation direction of the driving wheel is arranged opposite to the discharge direction of the mud discharge port 15. The mud is transported in the opposite direction of the mud discharge port 15 through the conveying assembly 11. During the transportation process, gravity and the impact of the continuously falling mud are used to cause the mesh conveyor belt on the conveying assembly 11 to shake, so that the liquid in the mud falls onto the second filter plate 17, so that stones, bricks, etc. in the mud are not retained, and the slope of the second filter plate 17 and the shaking motor 16 at its bottom are used to cause the retained mud blocks, bricks, etc. to be discharged from the mud discharge port 15 for centralized treatment.

[0052] See attached Fig. 9 As shown, a mesh conveyor belt is provided on the driving wheel and the driven wheel, and a conveyor chain 111 is symmetrically arranged on both sides of the mesh conveyor belt. The conveyor chain 111 rotates synchronously with the mesh conveyor belt. An L-shaped push plate 113 is arranged at intervals on the upper part of the mesh conveyor belt, and a flexible plate 112 is provided on the push plate 113. The length of the push plate 113 is greater than or equal to the spacing between the conveyor chains 111 on both sides of the mesh conveyor belt. The push plate 113 is arranged perpendicular to the conveying direction of the mesh conveyor belt. A fixed bottom plate 115 is provided below the push plate 113. The push plate 113 and the fixed bottom plate 115 are connected by fasteners. The conveyor chain 111 or the mesh conveyor belt or the combination of the conveyor chain 111 and the mesh conveyor belt is sandwiched between the push plate 113 and the fixed plate 115. The present invention separates large objects in the mud, such as mud blocks, bricks, and steel bars, by using a mesh conveyor belt on the conveyor belt assembly 11, to prevent them from entering the secondary treatment process to interfere with the subsequent mud dehydration efficiency and damage the equipment. A push plate 113 is provided on the mesh conveyor belt to limit the displacement of large objects in the mud, that is, to prevent the large objects from sliding directly toward the mud discharge port 15 after the mud reaches the conveyor belt assembly 11. The push plate 113 is used to push the large objects in the opposite direction of the mud discharge port 15, which helps to separate the mud on the upper part of these large objects, such as the mud on the surface of the brick. After such large objects fall onto the second filter plate 17, Under the action of the shaking motor 16, the mud on the surface of these objects is separated again during the relative shaking process, and the push plate 113 located on the adjacent surface of the second filter plate 17 cooperates with the flexible push plate 112 on its upper part to push these objects to move on the second filter plate 17, avoiding the accumulation of materials and the problem of excessive mud adhering to the materials discharged from the mud discharge port 15. At the same time, the method of arranging the flexible plate 112 on the upper part of the push plate 113 improves the restriction effect on large objects on the one hand, and prevents friction or jamming between the conveying component 11 and the second filter plate 17 on the other hand, that is, the friction between the push plate 113 and the second filter plate 17 is avoided by the flexible mesh plate 12.

[0053] A first filter plate 13 is provided between the conveying assembly 11 and the mud discharge port 15 . The first filter plate 13 is located in the feed chamber, and there is a gap between the bottom of the first filter plate 13 and the second filter plate 17 . The first filter plate 13 further prevents the mud from being directly discharged.

[0054] Embodiment 2:

[0055] The difference between this embodiment and embodiment 1 is that, see the attached Figure 2 , 4 As shown in Figures 6 and 7, the end of the stirring shaft 42 located in the direction of the feed chamber 32 is abutted against a support base 62, and the side of the support base 62 is connected to the inner ring of the bearing 60 through a connecting rod 61, and the outer ring of the bearing 60 is fixedly connected to the inner wall of the separation tube body 31. The shaking of the stirring shaft 42 during rotation is reduced by abutting the end of the stirring shaft 42 against the support base 62, that is, the axis deviation range of the two ends of the stirring shaft 42 during rotation is limited, so that the stirring blade 41 can be prevented from scratching the separation tube body 31 during high-speed rotation with the stirring shaft 42, and the possibility of increased power consumption of the first motor 40 is also reduced. The connecting rod 61 has a cutting effect on the upwardly displaced mud while ensuring the stable connection between the bearing 60 and the stirring shaft 42. The connecting rod 61 can destroy the original mud-liquid distribution state of the upwardly moving mud and promote the separation of water in the mud-liquid.

[0056] The support base 62 is a rotating body structure, and the interior of the support base 62 is hollow. The upper surface of the support base 62 has an inner groove, which is adapted to the stirring shaft 42. A first through hole 64 is provided on the groove surface of the inner groove. The lower surface of the support base 62 has an inner groove corresponding to the upper surface and a first through hole 64. The middle diameter of the support base 62 is larger than the diameters of the two ends of the support base 62, so that the support base 62 has two upper and lower inclined annular surfaces, and the upper and lower annular surfaces of the support base 62 are respectively surrounded by swing components 63. By designing the structure of the support base 62, its external structure is formed into a "flying saucer" shape, which has a guiding effect on the mud flowing up and down along the outer surface of the support base 62, avoiding excessive concentration of mud around the end of the stirring shaft 42, causing it to shake too much, and when the support base 62 and the connecting rod 61 rotate synchronously, the mud along its outer surface is prompted to flow in a spiral manner, which helps to remove water from the mud. In addition, the hollow design of the interior of the support base 62 and the opening of the first through hole 64 are used to avoid interference from mud or stones at the abutment between the end of the stirring shaft 42 and the support base 62. Specifically, when mud or stones appear between the stirring shaft 42 and the support base 62, the mud or stones can enter the first through hole 64 with the rotation, avoiding mud, stones, etc. from interfering with the effective abutment between the stirring shaft 42 and the support base 62.

[0057] The gap between the end of the stirring shaft 42 and the upper end of the inner groove of the supporting base 62 is less than or equal to the diameter of the first through hole 64. The purpose of this design is to prevent mud or stones larger than the first through hole 64 from entering the area around the joint between the stirring shaft 42 and the supporting base 62 and being unable to be discharged from the first through hole 64.

[0058] The swing assembly 63 includes two connecting plates 65 arranged parallel to each other, a swing rod 67 capable of rotation is connected between the connecting plates 65, a swing leaf 68 is connected to the swing rod 67 along the axis, the swing leaf 68 is bent, and there is a gap between the two sides of the swing leaf 68 and the connecting plate 65, a spring 66 is arranged between one side or both sides of the swing leaf 68 and the connecting plate 65, and the spring 66 is sleeved on the swing rod 67. The connecting plate 65 is vertically connected to the annular surface of the supporting base 62. The swing assembly 63 is designed to improve the pushing effect of the mud on the supporting base 62. The swing blade 68 on the swing assembly 63 is used to expand the contact area with the mud, thereby expanding the pushing effect of the mud on the supporting base 62 connected to the swing assembly 63, prompting the supporting base 62 to generate a rotational motion, and synchronously driving the connecting rod 61 connected thereto to rotate, so as to divert the upwardly moving mud and destroy the original mud-liquid distribution state of the mud to promote the separation of water in the mud and liquid. In addition, a rotatable swing rod 67 is provided on the swing assembly 63 to enable the swing blade 68 to swing with the impact of the mud, so as to avoid deformation of the swing blade 68 caused by excessive impact force of the mud. After the swing blade 68 is bent, its contact area with the mud is effectively ensured. Even when the swing blade 68 is in contact with the outer surface of the supporting base 62, the bent end of the swing blade 68 still has an area in contact with the mud. The swing speed of the swing blade 68 is limited by designing a spring 66 on the swing rod 67, that is, the first spring 66 elastically supports the swing blade 68 to reduce its rotation and swinging speed.

[0059] Embodiment 3:

[0060] The difference between this embodiment and embodiment 1 is that, see the attached Fig.10 As shown, the excess mud discharged from the discharge shell 50 and the liquid discharged from the second tube body 33 are sent to the auxiliary box 70, and the upper water inside the auxiliary box 70 is discharged by adding flocculant to the inside of the auxiliary box 70, and the mud at the bottom of the auxiliary box 70 and its bottom suspension are pumped out by the second pump body 72 and mixed and sent again through the first tube body 21 to the feed chamber 32 for mud dehydration treatment.

[0061] Embodiment 4:

[0062] See attached Figure 1-10 As shown, the mud treatment method using the mud treatment device has the following specific steps:

[0063] 1) The mud generated at the construction site and the like is sent into the first matrix 10, and the mud is transported in the opposite direction of the mud discharge port 15 by the conveying component 11. During the transportation process, gravity and the impact of the continuously falling mud are used to cause the mesh conveyor belt on the conveying component 11 to shake to make the liquid in the mud fall onto the second filter plate 17, so that stones, bricks, etc. in the mud are not retained, and the slope of the second filter plate 17 and the shaking motor 16 at its bottom are used to cause the retained mud, bricks, etc. to be discharged from the mud discharge port 15 for centralized treatment, and the mud is filtered through the second filter plate 17 so that the filter chamber 18 collects the primary filtered mud. At the same time, under the reverse transmission action of the conveying component 11, the mud placed in the first matrix 10 is prevented from being directly discharged from the mud discharge port, and the first filter plate 13 is used to further prevent the mud from being directly discharged.

[0064] 2) The first pump body 20 is used to separate the solid and liquid of the first matrix 10 to obtain mud, which is then sent to the second matrix 30 in batches. The first pump body 20 is controlled by an industrial computer to transport the mud into the second matrix 30 in batches, thereby ensuring the working efficiency of the second matrix 30 and giving the first motor 40 on the second matrix 30 downtime to avoid overheating or other damage.

[0065] 3) After the first pump body 20 extracts the slurry in the first base body 10 in batches and transports it to the feed chamber 32, the slurry continuously moves upward in the feed chamber 32, and the first motor 40 works synchronously to drive the stirring shaft 42 and the stirring blades on the upper part thereof to rotate and drive the slurry to rotate, and the water in the slurry is removed by centrifugal action. Similarly, as the water in the slurry is removed, the agglomerated slurry moves downward into the feed chamber 32 under the action of gravity. After completing the single batch processing, the obtained slurry is discharged by opening the solenoid valve below the feed chamber 32;

[0066] 4) The liquid discharged from the second tube body 33 is subjected to secondary treatment. The liquid discharged from the second tube body 33 is sent to the auxiliary box body 70, and the upper water body inside the auxiliary box body 70 is discharged by adding flocculants inside the auxiliary box body 70. The mud at the bottom of the auxiliary box body 70 and the bottom suspension are extracted by the second pump body 72 and mixed and sent to the feed chamber 32 through the first tube body 21 again for mud dehydration treatment.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
