Description

Technical Field

[0001] The present disclosure specifically discloses a mud-water separation device used in conjunction with an underwater dredging robot. Background Art

[0002] The dredging and pollution removal of rivers and ponds is a major problem related to the physical and mental health of urban residents and urban and rural environmental protection. Most of the traditional dredging methods in my country are "sea of ​​people" construction with shovels, cars and pumps. Although some of them are mechanized, the whole process from excavation, transportation to loading and transportation is far from being systematically mechanized. Therefore, not only is the dredging efficiency low and the labor intensity is high, but also the poor working environment has greatly affected the health of construction workers. Especially in the past two decades, with the continuous acceleration of my country's industrialization process and the rapid development of the economy, the siltation, blockage and pollution of rivers have become more and more serious. The country's policies and efforts on pollution control and environmental protection have also been continuously strengthened. The people's requirements and awareness of environmental protection are also getting stronger and stronger. Under this realistic situation, society urgently needs a modern and efficient dredging equipment. At present, the main construction methods for river dredging are: semi-manual and semi-mechanical construction, slurry suction construction, stirring suction construction, and mechanical excavation.

[0003] Mud and water separation equipment is also very important in cooperating with dredging robots. It is of great practical significance to complete dredging, sludge treatment and sludge transportation in one line to solve the problem of manpower and material resources. Dehydration of sludge has also become a major focus of cooperating with robot dredging. Direct discharge to the shore for manual consignment is even more wasteful of manpower and financial resources. It is urgent to develop a device that can effectively dehydrate the sludge on the shore. Summary of the invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide a mud-water separation device that can be used in conjunction with an underwater dredging robot.

[0009] According to the technical solution provided in the embodiment of the present application, there is at least one drainage hole and the drainage hole is arranged in a circular array around one end of the spiral conveying rod fixed to the bottom of the device body.

[0010] According to the technical solution provided in the embodiment of the present application, there is at least one mud discharge hole and the mud discharge hole is arranged in a circular array at the bottom of the side wall of the device body.

[0011] According to the technical solution provided in the embodiment of the present application, it also includes: a two-curved cleaning box, the bottom of which passes through the top of the device body into the interior thereof, and the bottom of the cleaning box is provided with cleaning holes arranged in a circular array, and a hollow spray ball is connected to the detergent hole; a spray hole is provided on the side wall of the spray ball; and a water inlet hole is provided on the top of the cleaning box.

[0012] According to the technical solution provided in the embodiment of the present application, the annular filter screen has an overall conical structure and is provided with a plurality of curved spikes distributed in an annular array on one side thereof which is relatively far away from the bottom of the device body.

[0013] According to the technical solution provided in the embodiment of the present application, it also includes: an anti-clogging component is fixedly connected to one end of the spiral conveying rod relatively close to the annular filter screen; the anti-clogging component includes: an anti-clogging ring fixedly connected to the spiral conveying rod and an anti-clogging rod fixedly connected to the side wall of the anti-clogging ring; a receiving groove for preventing contact with thorns is provided on the side wall of the anti-clogging rod relatively close to the annular filter screen, and the side wall is also provided with an elastic protrusion that directly contacts the annular filter screen.

[0014] According to the technical solution provided in the embodiment of the present application, a disturbance rod is provided longitudinally penetrating the cleaning box and the disturbance rod is respectively connected to the top wall and the bottom wall of the cleaning box through bearings; a disturbance piece with a sheet structure is fixed to the bottom of the disturbance rod and a plurality of disturbance holes with an inverted cone structure are provided on the disturbance piece; the top of the disturbance rod is transmission-connected to a micro motor.

[0015] According to the technical solution provided in the embodiment of the present application, the top wall of the cleaning box is a curved structure that bulges upward; and the disturbance rod is fixedly connected to one side of the disturbance member.

[0016] The technical scheme specifically discloses a structure of a mud-water separation device used in conjunction with an underwater dredging robot. The sludge entering from the feed port enters the end of the spiral conveying rod relatively close to the feed port through the extension pipe, and the driving mechanism starts and drives the spiral conveying rod to rotate, thereby driving the sludge to move along the spiral conveying rod to the side close to the annular filter screen. During the rotation of the spiral conveying rod, under the action of the centrifugal force generated by its rotation, the sludge is separated from the water carried in it. The sludge with a large specific gravity is easy to approach and adhere to the inner wall of the device body, and the water with a small specific gravity is close to the spiral conveying rod. The sludge approaches the annular filter screen continuously and is squeezed through the annular filter screen. The water separated after being squeezed enters between the annular filter screen and the bottom of the device body and is discharged through the drainage hole; and the sludge is discharged through the mud discharge hole on the side wall of the device body. During the entire dehydration process, the sludge can effectively prevent the water from being discharged from the mud discharge hole during the process of sludge being discharged from the mud discharge hole. Based on the above technical scheme, the technical scheme can effectively dehydrate the sludge, thereby effectively reducing the overall volume and weight of the sludge, which is convenient for subsequent transportation operations.

[0017] In order to solve the technical problem that sludge adheres to the side wall of the device body during use and is not conducive to discharge, the present technical solution provides a hydraulic structure and a scraper assembly connected thereto. After the hydraulic structure is started, it drives the scraper rod to reciprocate along the axial direction of the device body, and then drives the curved scraper plate connected to the scraper rod to reciprocate along the axial direction of the device body to clean the inner wall of the device body and promote the discharge of sludge. Specifically, the present technical solution further optimizes the structure of the scraper plate, and designs it into a structure of a first scraper plate and a second scraper plate. On the one hand, it can expand the effective area of ​​the scraper plate, and on the other hand, the second scraper plate is also provided with a strip-shaped through groove for facilitating the passage of sludge so as not to hinder the discharge of sludge.

[0018] In view of the situation where the inner wall of the device body needs to be cleaned after use, the present technical solution also provides a structural design of a cleaning box. A water inlet hole is provided at the top of the cleaning box and a cleaning hole is provided at the bottom. Water flows entering from the water inlet hole at the top of the cleaning box and enters the interior of the device body from the cleaning hole. Along with the rotation of the spiral conveying rod, the interior of the device body can be cleaned. In addition, the design provided by the present technical solution can also be used together with a hydraulic structure and a mud scraper assembly.

[0019] In order to facilitate the dehydration of sludge and the discharge of sludge on the annular filter, the technical solution optimizes the structure of the annular filter. Specifically, the annular filter in the technical solution is designed as a conical structure, and the side wall of the conical structure annular filter is inclined, which is convenient for the smooth discharge of the sludge thrown on it. In addition, considering that the sludge may be mixed with soft materials such as water plants that are not easy to be discharged from the mud discharge hole, the design and the spurs on the annular filter can cut off the soft materials during the rotation of the spiral conveying rod to facilitate its subsequent discharge.

[0020] In order to prevent the annular filter from being blocked, an anti-blocking assembly is also designed in this technical solution. The anti-blocking ring in the anti-blocking assembly is fixedly connected to the end of the spiral conveying rod that is relatively close to the annular filter. The anti-blocking rod fixedly connected to the anti-blocking ring can rotate in accordance with the upper end surface of the annular filter as the spiral conveying rod rotates, and the elastic protrusion on it can further clean the annular filter. In addition, in order to facilitate the spurs designed on the annular filter, a receiving groove is designed on the anti-blocking rod to prevent contact with the spurs.

[0021] The technical solution is further designed with a disturbance rod penetrating the cleaning box, and a micro motor is used to drive the disturbance rod. When water is ejected from the cleaning hole, the disturbance piece in contact with the water flow breaks up the water flow so that the water flow can contact the sludge on the inner wall of the device body, thereby helping to better clean the sludge attached to the inside. Specifically, the disturbance piece is eccentrically fixed to the disturbance rod so as to disturb the water flow to the maximum extent and expand the radiation area of ​​the water flow.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Please refer to Figure 1 A mud-water separation device is shown for use with an underwater dredging robot.

[0036] The mud-water separation device used in conjunction with the underwater dredging robot comprises: a hollow columnar device body 100 .

[0037] Specifically, the device body 100 is a hollow cylindrical structure. Figure 1 As shown, a driving mechanism 101 is provided on the top of the device body 100, and the output shaft of the driving mechanism 101 passes through the top of the device body 100; a spiral conveying rod 102 is fixedly connected to the free end of the output shaft of the driving mechanism 101, and the free end of the spiral conveying rod 102 is fixedly connected to the bottom wall of the device body 100; a feed port 103 is provided on the top of the device body 100, and an extension tube 104 is provided on the edge of the feed port 103, which is bent toward one end of the spiral conveying rod 102 relatively close to the feed port 103.

[0038] Based on the above design, the sludge entering from the feed port enters the end of the screw conveying rod relatively close to the feed port through the extension tube, and the drive mechanism starts and drives the screw conveying rod to rotate, thereby driving the sludge to move along the screw conveying rod to the side close to the annular filter. Specifically, the drive structure is a motor and related drive components to drive the screw conveying rod to rotate.

[0039] A drainage hole 105 is provided at the bottom of the device body 100, and an annular filter screen 106 capable of covering the drainage hole 105 is provided at the bottom thereof; the outer edge of the annular filter screen 106 is fixedly connected to the bottom of the device body 100, and the inner edge thereof is fixedly connected to an end of the spiral conveying rod 102 relatively away from the feed port 103; a mud discharge hole 107 is provided on the side wall of the device body 100 and is located above the annular filter screen 106.

[0040] in:

[0041] The annular filter screen is annular in structure as a whole, and its inner ring edge is connected to the screw conveying rod through a bearing so as not to hinder the rotation of the screw conveying rod; its outer ring edge is fixed to the bottom of the device body.

[0042] The sludge continuously moves downward along the axis of the device body, while the filter screen itself is fixed, so under the action of the sludge gravity, it contacts the annular filter screen to dehydrate the sludge. The water flow entering between the annular filter screen and the bottom of the device body is discharged through the drainage hole. The dehydrated sludge is discharged through the mud discharge hole. Optionally, the sludge after a dehydration operation can enter the device body again and undergo a secondary dehydration operation.

[0043] Optionally, there is at least one drainage hole 105 and the drainage hole 105 is arranged in a circular array around one end of the spiral conveying rod 102 fixed to the bottom of the device body 100 .

[0044] Optionally, there is at least one mud discharge hole 107 and the mud discharge hole 107 is arranged in a circular array at the bottom of the side wall of the device body 100 .

[0045] Based on the above design, during the rotation of the spiral conveying rod, under the action of the centrifugal force generated by its rotation, the silt is separated from the water it carries. The silt with a high specific gravity is easy to approach and adhere to the inner wall of the device body, while the water with a low specific gravity is close to the spiral conveying rod. The silt continuously approaches the annular filter screen and is squeezed through the annular filter screen. The separated water after being squeezed enters between the annular filter screen and the bottom of the device body and is discharged through the drainage hole; the silt is discharged through the mud discharge hole on the side wall of the device body. During the entire dehydration process, the silt can effectively prevent the water from being discharged from the mud discharge hole during the process of being discharged from the mud discharge hole. Based on the above technical scheme, the present technical scheme can effectively dehydrate the silt, thereby effectively reducing the overall volume and weight of the silt, and facilitating subsequent transportation operations.

[0046] Please refer to Figure 2 A mud-water separation device is shown for use with an underwater dredging robot.

[0047] At least two hydraulic structures 108 are arranged in a circular array around the driving mechanism 101 on the top of the device body 100; the output shaft of the hydraulic structure 108 passes through the top of the device body 100 and a scraper assembly 109 is provided on the free end of the output shaft; the scraper assembly 109 includes: a scraper rod 1091 fixedly connected to the free end of the output shaft of the hydraulic structure 108 and a curved scraper plate 1092 fixedly connected to the free end of the scraper rod 1091 and matching the inner wall of the device body 100.

[0048] In order to solve the technical problem that sludge adheres to the side wall of the device body and is not easy to be discharged during use, this embodiment provides a hydraulic structure and a sludge scraping assembly connected thereto.

[0049] The hydraulic structure is a conventional hydraulic cylinder and will not be described in detail here.

[0050] The scraper rod is fixedly connected to the output shaft of the hydraulic cylinder and reciprocates with the reciprocating movement of the output shaft, thereby driving the scraper blade thereon to move. The scraper blade loosens the sludge on the inner wall of the device body so that the sludge attached to the inner wall of the device body can be discharged under the action of centrifugal force.

[0051] The scraper blade has a curved structure as a whole to adapt to the inner wall of the device body.

[0052] After the hydraulic structure is started, it will drive the scraper rod to reciprocate along the axial direction of the device body, and then drive the curved scraper plate connected to the scraper rod to reciprocate along the axial direction of the device body to clean the inner wall of the device body and promote the discharge of sludge.

[0053] Please refer to Figure 3 A mud-water separation device is shown for use with an underwater dredging robot.

[0054] Please refer to Figure 3a An embodiment of a mud scraper assembly is shown.

[0055] There are two scraper blades 1092 and they are distributed axially along the scraper rod 1091. The first scraper blade 1092a is relatively close to the hydraulic structure and the second scraper blade 1092b is relatively far away from the hydraulic structure. The first scraper blade 1092a is provided with a strip-shaped through groove 1092c.

[0056] In this embodiment, the structure of the scraper blade is specifically optimized and designed into a structure of a first scraper blade and a second scraper blade.

[0057] After the hydraulic structure is started, it will drive the scraper rod to reciprocate along the axial direction of the device body, thereby driving the first scraper blade and the second scraper blade connected to the scraper rod to reciprocate along the axial direction of the device body to clean the inner wall of the device body and promote the discharge of sludge.

[0058] Based on the structure in this embodiment, on the one hand, the effective area of ​​the scraper blade can be expanded, and on the other hand, the second scraper blade is also provided with a strip-shaped through groove for facilitating the passage of sludge so as not to hinder the discharge of sludge.

[0059] Optionally, refer to Figure 3b An embodiment of a scraper assembly is shown. A mud lifting rod 1092d distributed along the axial direction of the device body 100 is fixedly connected to the free end of the second scraper plate 1092b, and a rotatable mud lifting piece 1092e is ring-connected to the mud lifting rod 1092d. Specifically, the mud lifting rod is a rod-shaped structure, and a mud lifting piece that can rotate around the mud lifting rod is ring-connected thereon.

[0060] After the hydraulic structure is started, it will drive the scraper rod to reciprocate along the axial direction of the device body, thereby driving the first scraper blade and the second scraper blade connected to the scraper rod to reciprocate along the axial direction of the device body, and the mud raising rod will also reciprocate. Since the mud raising rod is a rod-shaped structure, it can longitudinally decompose the sludge on the inner wall of the device body, so as to loosen the sludge in a larger area. In addition, a mud raising sheet that can rotate around the mud raising rod is provided on it, and the mud raising sheet can also have a good loosening effect on the sludge in the lateral direction.

[0061] Specifically, please refer to Figure 3c An embodiment of a mud scraping assembly is shown. Two mud lifting rods 1092d are fixedly connected to the free end of the second mud scraping plate 1092b, and a curved mud disturbing plate 1092f matching the side wall of the device body is passed between the two mud lifting rods 1092d on each second mud scraping plate 1092b. The design of the mud disturbing rod can enhance the effect of the mud lifting rod and the mud lifting sheet.

[0062] Please refer to Figure 4 A mud-water separation device is shown for use with an underwater dredging robot.

A mounting hole for accommodating the cleaning box is provided on the top of the device body, and the edge of the mounting hole is sealed and connected to the outer side wall of the cleaning box.

[0066] Specifically, the number of cleaning boxes can be three and the three cleaning boxes are distributed in a circular array on the top of the device body. Of course, four or five cleaning boxes can be set according to the bearing strength of the device body.

[0067] The top of the cleaning box is provided with a water inlet hole, which may be one or two in particular, and the water inlet hole is externally connected to a water inlet pipeline. Optionally, the water inlet pipeline may be a pressurized water pipe to ensure that the water entering the cleaning box has a certain pressure, so that the water enters the cleaning box from the water inlet hole, and then enters the spray ball in the cleaning hole and sprays out to clean the inner wall of the device body.

[0068] In order to improve the cleaning effect of the device body, a fixed cleaning object may be arranged in the cleaning box, which is dissolved under the flushing action of the water flow entering from the water inlet hole, and then enters the spray ball with the water flow and is scattered out.

[0069] Optionally, the spray ball is designed to disperse the water flow into multiple streams so as to flush a larger inner wall area of ​​the device body.

[0070] Furthermore, the cleaning box provided by the present technical solution can also be used together with the hydraulic structure and the mud scraping assembly.

[0071] Please refer to Figure 5 A mud-water separation device is shown for use with an underwater dredging robot.

[0072] The annular filter screen 106 is in a conical structure as a whole and is provided with a plurality of curved spikes 1061 distributed in an annular array on a side thereof relatively far from the bottom of the device body 100 .

[0073] The conical ring filter has an inclined side wall, which facilitates the smooth discharge of the sludge thrown onto it. In addition, considering that the sludge may be mixed with soft materials such as water plants that are not easy to be discharged from the mud discharge hole, the design and the thorns on the ring filter can cut off the soft materials during the rotation of the spiral conveying rod to facilitate its subsequent discharge.

[0074] During the rotation of the spiral conveying rod, a steady stream of sludge advances along its axial spiral, and when it comes into contact with the annular filter, it can cut off the soft material to facilitate its subsequent discharge.

[0075] Optionally, the thorn has an overall curved structure and a sharp end.

[0076] Please refer to Figure 6 A mud-water separation device is shown for use with an underwater dredging robot.

The anti-clogging rod fixed to the anti-clogging ring can rotate in accordance with the upper end surface of the annular filter screen as the spiral conveying rod rotates, and the elastic protrusion thereon can further clean the annular filter screen.

[0079] In order to accommodate the thorns designed on the annular filter, a receiving groove is designed on the anti-clogging rod to prevent contact with the thorns.

[0080] Specifically, the receiving groove is a through groove and has a curved structure.

[0081] Please refer to Figure 7 A mud-water separation device is shown for use with an underwater dredging robot.

[0082] The cleaning box 110 is provided with a disturbance rod 112 which penetrates longitudinally, and the disturbance rod 112 is respectively connected to the top wall and the bottom wall of the cleaning box 110 through bearings; a disturbance piece 1121 with a sheet structure is fixed to the bottom of the disturbance rod 112, and a plurality of disturbance holes with an inverted cone structure are provided on the disturbance piece 1121; the top of the disturbance rod 112 is transmission-connected to a micro motor.

[0083] In this embodiment, a disturbance rod is designed to penetrate the cleaning box, and a micro motor is used to drive the disturbance rod.

[0084] When water flow is sprayed out of the cleaning hole, the disturbing member in contact with the water flow breaks up the water flow so that the water flow can contact the sludge on the inner wall of the device body, thereby helping to better clean the sludge attached to the inside.

[0085] Specifically, the top wall of the cleaning box 110 is in a curved structure that bulges upward; the disturbance rod 112 is fixed to one side of the disturbance member 1121 .
