Description

Technical Field

[0001] The invention belongs to the technical field of mud processing equipment and relates to a mud separation and solidification device. Background Art

[0002] In the renovation of heating pipe networks in old residential areas, a large amount of mud is generated during construction. For the treatment of mud, it is usually precipitated in a three-stage sedimentation tank and then transported to a waste dump by tank truck. This method is due to the large amount of engineering mud, high water content, high treatment cost, and traffic control factors that cannot guarantee continuous transportation.

[0003] In order to solve the above problems, various solidification equipment capable of on-site treatment of mud has emerged. For example, an integrated sewage treatment equipment disclosed in the CN216513405U patent has a working principle of sending the mud into the filter chamber for preliminary filtration, and then sending it to the filter press structure for filtration through the diversion structure. The filter press structure is a "7"-shaped pressure plate that fits each other, and the two sets of pressure plates achieve the extrusion of the mud through mutual movement.

[0004] However, in the process of engineering construction, once the large-diameter jacking pipe starts to push, it cannot be stopped (or the jacking pipe is a continuous operation), and the slurry is discharged continuously. Although the technical solution of the above patent can realize the solidification treatment of the slurry, the solidified slurry needs to be pushed to the discharge port by the pressing plate.

At the same time, a stirring structure is also provided in the reaction tower 1a, so as to accelerate the mixing effect of the flocculant and the mud and improve the flocculation and sedimentation effect.

[0069] The mud treated by the dosing unit 1 is transported to the sedimentation unit 2 through the delivery pump pipeline for further treatment. According to one embodiment of the present invention, the sedimentation unit 2 includes a sedimentation tower 21, the sedimentation tower 21 is provided with a central pipe 22, the mud outlet pipe 1c is connected to the central pipe 22 through a pipeline, the sedimentation tower 21 includes an upper side portion 23 and a conical portion 24, an umbrella-shaped baffle 25 is provided at the lower end outlet of the central pipe 22, the upper side portion 23 is connected to a water outlet pipe 26, and the conical portion 24 is connected to the solidification unit 3 through a pipeline. After the mud enters the sedimentation tower 21 through the central pipe 22, the mud is blocked by the umbrella-shaped baffle 25 and distributed to the entire horizontal section, and flows slowly upward. The suspended particles whose sedimentation speed is greater than the rising speed of the water flow sink into the conical portion 24, and the supernatant is discharged through the water outlet pipe 26. The mud settled in the conical portion 24 is transported to the solidification unit 3 for further solidification treatment.

[0070] Combination Figure 1 , Figure 5-Figure 19 As shown, according to one embodiment of the present invention, the curing unit 3 includes a curing box 4 and a water tank 5 connected to both sides of the curing box 4. The side wall of the curing box 4 is provided with a water outlet 41 connected to the water tank 5. A guide plate 411 is also provided on the lower side of the water outlet 41, so that the moisture in the mud in the curing box 4 can flow smoothly into the water tank 5 through the water outlet 41.

[0071] In this embodiment, a box cover 6 is detachably connected to the curing box 4, and a feed port 61 is provided on the box cover 6. The mud settled by the sedimentation unit 2 is transported to the curing box 4 through the feed port 61.

[0072] by Fig. 9 Taking the direction shown as an example, in the initial state of the mud separation and solidification device of the present invention, the filter press plate 9 is located at the right discharge port 42. At this time, the mud enters the solidification box 4 through the feed port 61, and the mud is located on the left side of the filter press plate 9. While the mud is introduced, the driving device 10 drives the filter press plate 9 to move to the left, pushing the mud on the left to move to the left so that the mud is located between the filter press plate 9, the baffle structure 7, and the upper baffle 8. Through the filtering action of the filter press plate 9, the water in the mud is further squeezed out and discharged into the water storage tank 5 through the water outlet 41. Among them, after the filter press plate 9 moves to the left through the feed port 61, the uninterrupted introduction of the mud will fall on the right side of the filter press plate 9. After the left side filtering is completed, the driving device 10 drives the filter press plate 9 to move to the right to push and filter the mud on the right.

Under the limiting action of the movement guide grooves 12, the transmission structure 11 drives the baffle structure 7 to move a predetermined distance and then separates from the baffle structure 7.

[0074] The mud separation and solidification device of the present invention, through the arrangement of the transmission structure 11, the baffle structure 7 and the motion guide groove 12, can drive the movement of the baffle structure 7 when the filter plate 9 moves to the other side after filtering the mud on one side, thereby realizing the opening of the discharge port 42 and the discharge of the material after filtering.

[0075] The baffle structure 7, the upper baffle 8, the filter press plate 9, the drive device 10, the transmission structure 11 and the motion guide groove 12 of the present invention are described in detail below:

[0077] In the mud separation and solidification device of the present invention, when the mud is filtered, the discharge baffle 71 is matched at the discharge chute 431. After the filtration is completed, the filter plate 9 moves in the opposite direction, so that the transmission structure 11 drives the movable baffle 73 to move, thereby realizing the movement of the discharge baffle 71, and the discharge port 42 is opened to realize the discharge. After the movable baffle 73 moves a certain distance, it is separated from the transmission structure 11, and the movable baffle 73 and the discharge baffle 71 are reset under the action of the reset spring 45.

[0078] Combination Fig.10 and Fig.11 As shown, the inner wall of the curing box 4 of the present invention is provided with a guide groove 101, and the upper surface of the curing box 4 is provided with a second guide groove 102, the second guide groove 102 is connected with the guide groove 101, the lengths of the guide groove 101 and the second guide groove 102 are equal, and both are located between the two upper baffles 8, and the lengths of the guide groove 101 and the second guide groove 102 are the moving stroke of the filter press plate 9. According to one embodiment of the present invention, the driving device 10 includes a threaded rod 103 and a driving motor 104, wherein one end of the threaded rod 103 is located in the guide groove 101 and is rotatably connected to the guide groove 101, and the other end passes through the guide groove 101 and the curing box 4 in sequence and extends out of the curing box 4. The driving motor 104 is connected to the threaded rod 103, and drives the threaded rod 103 to rotate forward or reversely.

[0079] Combination Fig.10 , Figure 12-16 As shown, in this embodiment, the filter press plate 9 has a slider structure 91, the slider structure 91 is threadedly matched with the threaded rod 103, and the slider structure 91 is adapted to the guide groove 101. When the drive motor 104 is working, the threaded rod 103 is driven to rotate, and the slider structure 91 is adapted to the guide groove 101, so that the rotation direction of the slider structure 91 is limited, and then the slider structure 91 moves along the guide groove 101.

[0080] According to an embodiment of the present invention, the transmission structure 11 includes a transmission plate 111, the transmission plate 111 has a sliding fitting portion 112 fixedly connected to the slider structure 91, and the sliding fitting portion 112 is slidingly matched with the second guide groove 102. When the filter press plate 9 moves, the transmission structure 11 moves synchronously. In this embodiment, the transmission plate 111 has a mounting groove 113, a mounting guide cylinder 114 is fixedly provided in the mounting groove 113, a spring 115 is fixedly connected in the mounting groove 113, and the other end of the spring 115 passes through the mounting guide cylinder 114 and is connected to a driving plate 116, and the driving plate 116 abuts against the limit groove 732 to drive the movable baffle 73 to move.

[0081] According to one embodiment of the present invention, a slide groove 117 is provided on the driving plate 116, a guide slider 118 matching the slide groove 117 is provided in the mounting groove 113, a sliding groove 119 is provided on the side wall of the transmission plate 111 facing the curing box 4, and a sliding column 120 is fixedly provided on the driving plate 116, and the sliding column 120 is slidably matched with the sliding groove 119 and extends out of the sliding groove 119. The sliding column 120 moves upward along the sliding groove 119, and can drive the driving plate 116 to retract into the transmission plate 111 along the guide slider 118.

[0082] Combination Figure 5 , Figure 6 , Fig.10 , Fig.12 , Figure 20-Figure 25 As shown, the front end of the sliding column 120 in the present invention is a hemispherical structure, and the sliding column 120 is slidably matched with the motion guide groove 12. According to an embodiment of the present invention, the motion guide groove 12 includes a horizontal portion 121, an inclined rising portion 122, a second horizontal portion 123, an inclined descending portion 124, a third horizontal portion 125, a second inclined rising portion 126, a fourth horizontal portion 127, and a second inclined descending portion 128 connected end to end in sequence. In this way, combined with Fig. 9 and Fig. 20As shown, when the filter plate 9 moves to the left, the sliding column 120 moves along the horizontal part 121. At this time, the driving plate 116 is in the initial state, and the lower end of the driving plate 116 is lower than the flange part 731. In this way, the filter plate 9 moves, and the driving plate 116 moves against the limiting groove 732 to drive the moving baffle 73 to move, thereby realizing the opening of the discharge port 42, so that the solidified mud after the filter press can fall from the discharge port 42. According to the concept of the present invention, the discharged solidified mud can be manually transported regularly, and of course, a conveyor belt or other device can be set under the discharge port 42 to transport the solidified mud to a designated position. When the sliding column 120 moves to the inclined rising part 122, the sliding column 122 rises along the inclined rising part 122. At this time, the driving plate 116 gradually rises to be separated from the moving baffle 73, and the moving baffle 73 is reset under the action of the reset spring 45. The moving distance of the movable baffle 73, or the disengagement position of the driving plate 116 and the movable baffle 73, should be before the filter press plate 9 moves to the feed port 61. In this way, when the filter press plate 9 moves to the feed port 61, the discharge baffle 71 has been reset, and the filter press plate 9 continues to move (filtering the mud on the left side of the filter press plate 9), and the mud will enter the right side of the filter press plate 9 for storage to prevent the mud on the right side from leaking out of the discharge port 42. The sliding column 120 continues to move along the second horizontal portion 123. At this time, the driving plate 116 moves to the left in a telescopic state. Then the sliding column 120 continues to move along the inclined descending portion 124. At this time, the driving plate 116 gradually extends and finally moves to the left side of the left movable baffle 73. The driving plate 116 does not contact the movable baffle 73 during the extension movement. When the sliding column 120 moves to the lowermost end of the inclined descending portion 124, the driving plate 116 is located on the left side of the movable baffle 73, and the filter press plate 9 completes the filtration action. After that, the filter press plate 9 moves to the right, the sliding column 120 moves along the third horizontal portion 125, and the driving plate 116 drives the movable baffle 73 on the left to move, completing the left side unloading. Then the sliding column 120 rises along the second inclined ascending portion 126, the driving plate 116 shrinks again, and the movable baffle 73 on the left is reset. The sliding column 120 continues to move along the fourth horizontal portion 127, and the filter press plate 9 processes the mud on the right side. The sliding column 120 moves along the second inclined descending portion 128, the driving plate 116 gradually extends, and finally is located on the right side of the movable baffle 73 on the right side, completing a filtration cycle. By repeating the above process in this way, continuous filtration and discharge processing on the left and right sides can be achieved.

[0084] With such a configuration, when the sliding column 120 moves along the inclined ascending portion 122, the sliding column 120 passes through the inclined surface of the lifting block 1223 to gradually compress the lifting block 1223 to achieve smooth operation of the sliding column 120. At this time, the second lifting block 1273 can be used as a limiter and transition piece to prevent the sliding column 120 from getting stuck. Similarly, when the sliding column 120 moves along the fourth horizontal portion 127, the sliding column 120 passes through the inclined surface of the second lifting block 1273 to gradually compress the second lifting block 1273 to achieve smooth operation of the sliding column 120. At this time, the lifting block 1223 acts as a limiter and transition piece to prevent the sliding column 120 from getting stuck.

[0085] Combination Figure 5 , Figure 6 , Fig. 9 and Fig.10 As shown, according to one embodiment of the present invention, there is a gap between the upper baffle 8 and the box cover 6, and a vertical driving device 81 is provided on the box cover 6. The vertical driving device 81 passes through the box cover 6 and is connected to the upper baffle 8 to drive the upper baffle 8 to move up and down.

[0086] Take the upper baffle plate 8 on the left side of the curing box 4 as an example. When the right side completes the slurry filtration, the filter plate 9 moves to the left, driving the discharge baffle plate 71 to fully open, and the vertical drive device 81 works to drive the upper baffle plate 8 to move downward, so that the upper baffle plate 8 can provide a downward force to the cured material, so that the cured material can fall smoothly under the action of the driving force and gravity. The setting form of the vertical drive device 81 is not limited, for example, it can be set as a drive device such as an electric push rod.

[0087] The working process of the mud separation and solidification device of the present invention is as follows (with Fig. 9 The position of the medium pressure filter plate 9 is the initial state):

[0088] The mud treated by the dosing unit 1 and the sedimentation unit 2 is sent to the curing box 4 through the feed port 61. At this time, the mud falls on the left side of the filter press plate 9. While the mud is being introduced, the drive motor 104 works, so that the filter press plate 9 moves to the left. The filter press plate 9 moves to the left, and the transmission plate 111 and the drive plate 116 move to the left synchronously. Under the limit guidance of the motion guide groove 12, the drive plate 116 first drives the right movable baffle 73 to move so that the discharge port 42 is in a fully open state. At the same time, the vertical drive device 81 drives the upper baffle 8 to move downward to realize the discharge of the solidified material on the right side. Then the drive plate 116 shrinks, the right movable baffle 73 is reset, the filter press plate 9 moves to the feed port 61, and the filter press plate 9 continues to move to the left. The mud passes through the feed port 61 and falls on the right side of the filter press plate 9 for storage. The filter plate 9 continues to move to the left to filter the mud on the left side, and the driving plate 116 moves to the left side of the movable baffle 73 on the left side under the limit of the motion guide groove 12. Then, the filter plate 9 moves to the right, and the driving plate 116 moves, driving the movable baffle 73 on the left side to move to the right, so as to realize the full opening of the discharge port 42 on the left side. At the same time, the vertical driving device 81 on the left side drives the upper baffle 8 on the left side to move downward, so as to realize the discharge of the solidified material on the left side. After the driving plate 116 moves a certain distance in the horizontal direction, it gradually shrinks inward until it is separated from the movable baffle 73 on the left side, and the movable baffle 73 on the left side is reset, and the discharge port 42 on the left side is in a closed state. The filter plate 9 continues to move to the right to filter the mud on its right side. When the filter plate 9 moves over the feed port 61, the mud will fall on the left side of the filter plate 9 for storage. When the filter plate 9 completes the filtration of the mud on the right side, the driving plate 116 is located on the right side of the movable baffle 73 on the right side. Afterwards, the above process is repeated to achieve continuous treatment of the mud.

[0089] The mud separation and solidification device of the present invention can realize uninterrupted processing of mud. Compared with the prior art, it can realize automatic discharge of solidified materials, and the discharge method is safe and reliable, and the overall mud separation and solidification efficiency is high.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
