Description

Technical Field

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

[0002] In the project of renovating the heating pipe network of old residential areas, a large amount of mud will be generated during construction operations. For the treatment of mud, it is usually settled in a three-stage sedimentation tank and then transported to a waste dump by a tank truck. Due to the large amount of engineering mud, high water content, and high treatment cost, continuous transportation cannot be guaranteed due to traffic control factors.

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

[0004] However, during the engineering construction process, once the large-diameter pipe jacking starts, it cannot stop (or the pipe jacking is a continuous operation), and the slurry discharge is continuous. Although the technical solution in the above patent can achieve the solidification treatment of mud, the solidified mud needs to be pushed to the discharge port by the pressing plate, and the mud cannot be continuously transported for solidification treatment during this process. Therefore, it cannot meet the usage requirements at the construction site. Summary of the Invention

[0066] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0067] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be elaborated one by one here, but the embodiments of the present invention are not limited to the following embodiments.

[0068] Combined with Figures 1 - 25 As shown, the present invention provides a mud separation and solidification device, which includes a medicine adding unit 1, a sedimentation unit 2, and a solidification unit 3 connected in sequence. According to an embodiment of the present invention, the medicine adding unit 1 includes a reaction tower 1a, and the reaction tower 1a is respectively connected with a mud inlet pipe 1b, a mud outlet pipe 1c, and a medicine adding pipe 1d. According to the concept of the present invention, the mud produced during the pipe jacking operation can be first transported to a mud collection pool, and the mud collection pool and the mud inlet pipe 1b are connected by a delivery pump pipeline to transport the mud to the reaction tower 1a. Flocculants such as cationic polyacrylamide can be added to the mud through the medicine adding pipe 1. 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 precipitation effect.

[0069] The mud treated by the medicine adding unit 1 is transported to the sedimentation unit 2 through a delivery pump pipeline for further treatment. According to an 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, and the mud outlet pipe 1c is connected to the central pipe 22 through a pipeline. The sedimentation tower 21 includes an upper side part 23 and a conical part 24. An umbrella-shaped baffle 25 is provided at the lower end outlet of the central pipe 22. The upper side part 23 is connected with a water outlet pipe 26, and the conical part 24 is connected to the solidification unit 3 through a pipeline. When the mud enters the sedimentation tower 21 through the central pipe 22, the mud is blocked by the umbrella-shaped baffle 25 and distributed around the entire horizontal section, flowing upward slowly. Suspended particles with a sedimentation speed greater than the water flow rising speed sink into the conical part 24, and the supernatant is discharged through the water outlet pipe 26. The mud sedimented in the conical part 24 is transported to the solidification unit 3 for further solidification treatment.

[0070] Combined with Figure 1 、 Figures 5 - 19 As shown, according to an embodiment of the present invention, the solidification unit 3 includes a solidification box body 4 and water storage pools 5 connected to both sides of the solidification box body 4. The side wall of the solidification box body 4 is provided with a water outlet hole 41 connected to the water storage pool 5, and a flow guide plate 411 is also provided below the water outlet hole 41, so that the water in the mud in the solidification box body 4 can flow smoothly to the water storage pool 5 through the water outlet hole 41.

[0071] In this embodiment, a lid 6 is detachably connected to the curing box body 4. An inlet 61 is provided on the lid 6. The slurry sedimented by the sedimentation unit 2 is transported into the curing box body 4 through the inlet 61. On both sides of the bottom of the curing box body 4 in the length direction, discharge ports 42 are symmetrically provided. A baffle structure 7 is provided at the discharge port 42. Above the discharge port 42 in the curing box body 4, an upper baffle 8 is provided. A filter pressing plate 9 is slidably fitted in the curing box body 4. A driving device 10 is provided at the upper end of the curing box body 4 to drive the filter pressing plate 9 to move, so as to push the slurry entering through the inlet 61 between the filter pressing plate 9, the inner wall of the curing box body 4, the baffle structure 7 and the upper baffle 8 and perform filter pressing.

[0072] Taking Figure 9 the direction shown as an example, in the initial state of the slurry separation and curing device of the present invention, the filter pressing plate 9 is located at the right discharge port 42. At this time, the slurry enters the curing box body 4 through the inlet 61, and the slurry is located on the left side of the filter pressing plate 9. While the slurry is being fed, the driving device 10 works to drive the filter pressing plate 9 to move leftward, pushing the slurry on the left side to move leftward so that the slurry is located between the filter pressing plate 9, the baffle structure 7 and the upper baffle 8. Through the filter pressing action of the filter pressing plate 9, the water in the slurry is further squeezed out and discharged into the storage pool 5 through the water outlet holes 41. Among them, when the filter pressing plate 9 moves leftward through the inlet 61, the continuously fed slurry will fall on the right side of the filter pressing plate 9. After the left side is filter pressed, the driving device 10 drives the filter pressing plate 9 to move rightward to push and filter the slurry on the right side. In this way, through the periodic left and right movement of the filter pressing plate 9, continuous curing treatment of the slurry can be achieved. The whole process can ensure continuous transportation and treatment of the slurry, avoiding shutdown operations from affecting the project progress.

[0073] Combined with Figure 5 、 Figure 10 、 Figures 12 - 16 As shown, for the slurry separation and curing device of the present invention, transmission structures 11 are symmetrically provided on both sides of the filter pressing plate 9. Movement guiding grooves 12 are symmetrically provided on the outer side wall of the curing box body 4. Under the limiting action of the movement guiding grooves 12, the transmission structures 11 drive the baffle structure 7 to move a predetermined distance and then disengage from the baffle structure 7.

[0074] For the slurry separation and curing device of the present invention, through the settings of the transmission structure 11, the baffle structure 7 and the movement guiding grooves 12, during the process of the filter pressing plate 9 moving to the other side after filter pressing the slurry on one side, the movement of the baffle structure 7 can be driven, so as to open the discharge port 42 and realize the discharge of the filter pressed material.

[0075] The following is a detailed description of the baffle structure 7, the upper baffle 8, the filter pressing plate 9, the driving device 10, the transmission structure 11 and the movement guiding grooves 12 of the present invention:

[0076] Combined with Figure 7 、 Figure 9, Figures 17 - 19 As shown in the figure, avoiding grooves 43 are symmetrically arranged at the bottom of the curing box body 4 of the present invention. The discharge port 42 is located in the avoiding groove 43, and a discharge chute 431 is arranged on the avoiding groove 43. The baffle structure 7 includes a discharge baffle 71 and a moving baffle 73. The discharge baffle 71 is located in the avoiding groove 43 and below the discharge port 42. The discharge baffle 71 has a discharge slider 72 which is in sliding fit with the discharge chute 431. The moving baffle 73 is in contact with the bottom surface of the curing box body 4 and fixedly connected to the discharge baffle 71. A flange portion 731 is arranged on the moving baffle 73, and a limiting groove 732 is arranged on the flange portion 731. In this embodiment, a reset guiding cylinder 44 is fixedly arranged on the bottom surface of the curing box body 4, a reset spring 45 is installed in the reset guiding cylinder 44, and the other end of the reset spring 45 is fixedly connected to the moving baffle 73.

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

[0078] Combined with Figure 10 and Figure 11 As shown in the figure, guiding grooves 101 are arranged on the inner wall of the curing box body 4 of the present invention, and a second guiding groove 102 is arranged on the upper surface of the curing box body 4. The second guiding groove 102 is communicated with the guiding groove 101. The guiding groove 101 and the second guiding groove 102 are equal in length and are both located between the two upper baffles 8. The length of the guiding groove 101 and the second guiding groove 102 is the moving stroke of the pressure filter plate 9. According to an embodiment of the present invention, the driving device 10 includes a threaded rod 103 and a driving motor 104. One end of the threaded rod 103 is located in the guiding groove 101 and is rotatably connected to the guiding groove 101, and the other end sequentially passes through the guiding groove 101 and the curing box body 4 and extends outside the curing box body 4. The driving motor 104 is connected to the threaded rod 103 to drive the threaded rod 103 to rotate forward or reversely.

[0079] Combined with Figure 10 、 Figures 12 - 16 As shown in the figure, in this embodiment, the pressure filter plate 9 has a slider structure 91. The slider structure 91 is in threaded fit with the threaded rod 103 and is adapted to the guiding groove 101. When the driving motor 104 works, it drives the threaded rod 103 to rotate. The adaptation setting of the slider structure 91 and the guiding groove 101 limits the rotation direction of the slider structure 91, and then it moves along the guiding 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 fit portion 112 which is fixedly connected to the slider structure 91, and the sliding fit portion 112 is slidably fitted 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. An installation guide cylinder 114 is fixedly arranged in the mounting groove 113, and a spring 115 is fixedly connected in the mounting groove 113. The other end of the spring 115 passes through the installation guide cylinder 114 and is connected to a driving plate 116. The driving plate 116 abuts against the limit groove 732 to drive the moving baffle 73 to move.

[0081] According to an embodiment of the present invention, a chute 117 is provided on the driving plate 116, a guiding slider 118 which is matched with the chute 117 is arranged in the mounting groove 113, a sliding groove 119 is provided on the side wall of the transmission plate 111 facing the curing box body 4, and a sliding column 120 is fixedly arranged on the driving plate 116. The sliding column 120 is slidably fitted with the sliding groove 119 and extends out of the sliding groove 119. When the sliding column 120 moves upward along the sliding groove 119, it can drive the driving plate 116 to contract into the transmission plate 111 along the guiding slider 118.

[0082] Combined with Figure 5 、 Figure 6 、 Figure 10 、 Figure 12 、 Figures 20 - 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 fitted with the movement guide groove 12. According to an embodiment of the present invention, the movement 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 which are connected end to end in sequence. With such a setting, combined with Figure 9 and Figure 20As shown, when the filter pressing plate 9 moves to the left, the sliding column 120 moves along the horizontal portion 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 portion 731. Thus, as the filter pressing plate 9 moves, the driving plate 116 moves against the limit groove 732 to drive the moving baffle 73 to move, thereby opening the discharge port 42, so that the filtered and solidified mud can fall from the discharge port 42. According to the concept of the present invention, the discharged solidified mud can be manually transferred regularly, or of course, a conveyor belt or other devices can be provided below the discharge port 42 to convey the solidified mud to a designated position. When the sliding column 120 moves to the inclined rising portion 122, the sliding column 122 rises along the inclined rising portion 122. At this time, the driving plate 116 gradually rises and disengages from the moving baffle 73, and the moving baffle 73 is reset under the action of the return spring 45. The moving distance of the moving baffle 73, or rather, the disengagement position of the driving plate 116 from the moving baffle 73, should be before the filter pressing plate 9 moves to the feed port 61. With such a setting, when the filter pressing plate 9 moves to the feed port 61, the discharge baffle 71 has been reset. The filter pressing plate 9 continues to move (to filter the mud on the left side of the filter pressing plate 9), and the mud will enter the right side of the filter pressing plate 9 for storage, preventing the mud on the right side from leaking out from the discharge port 42. The sliding column 120 continues to move along the second horizontal portion 123. At this time, the driving plate 116 is in the telescopic state and moves to the left. 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 of the left moving baffle 73, and the driving plate 116 does not contact the moving baffle 73 during the stretching movement. When the sliding column 120 moves to the lowest end of the inclined descending portion 124, the driving plate 116 is located on the left side of the moving baffle 73, and at the same time, the filter pressing plate 9 completes the filtering action. After that, the filter pressing plate 9 moves to the right, the sliding column 120 moves along the third horizontal portion 125, and the driving plate 116 drives the left moving baffle 73 to move to complete the left-side discharging. Then the sliding column 120 rises along the second inclined rising portion 126, the driving plate 116 contracts again, and the left moving baffle 73 is reset. The sliding column 120 continues to move along the fourth horizontal portion 127, and the filter pressing 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 right moving baffle 73, completing a filtering cycle. By repeating the above process, continuous filtering and discharging processes on both the left and right sides can be achieved.

[0083] According to an embodiment of the present invention, to ensure the movement stability of the sliding column 120 and the telescopic stability of the driving plate 116, in the mud separation and solidification device of the present invention, a lifting groove 1221 is provided in the inclined rising part 122. A lifting spring 1222 is fixedly provided in the lifting groove 1221. The upper end of the lifting spring 1222 is fixedly connected to a lifting block 1223, and the upper surface of the lifting block 1223 is an inclined surface. A lifting guide groove 1224 is provided in the lifting groove 1221, and a lifting slider 1225 is provided on the lifting block 1223 to cooperate with the lifting guide groove 1224. At the same time, a second lifting groove 1271 is provided in the fourth horizontal part 127. A second lifting spring 1272 is fixedly provided in the second lifting groove 1271. The upper end of the second lifting spring 1272 is fixedly connected to a second lifting block 1273, and the upper surface of the second lifting block 1273 is an inclined surface. A second lifting guide groove 1274 is provided in the second lifting groove 1271, and a second lifting slider 1275 is provided on the second lifting block 1273 to cooperate with the second lifting guide groove 1274.

[0084] With such a setting, when the sliding column 120 moves along the inclined rising part 122, the sliding column 120 gradually compresses the lifting block 1223 through the inclined surface of the lifting block 1223 to achieve the smooth operation of the sliding column 120. At this time, the second lifting block 1273 can be used as a limiting and transitional member to prevent the sliding column 120 from getting stuck. Similarly, when the sliding column 120 moves along the fourth horizontal part 127, the sliding column 120 gradually compresses the second lifting block 1273 through the inclined surface of the second lifting block 1273 to achieve the smooth operation of the sliding column 120. At this time, the lifting block 1223 is used as a limiting and transitional member to prevent the sliding column 120 from getting stuck.

[0085] Combined Figure 5 、 Figure 6 、 Figure 9 and Figure 10 As shown in, according to an embodiment of the present invention, there is a gap between the upper baffle 8 and the box cover 6. 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] Taking the upper baffle 8 on the left side in the curing box body 4 as an example for illustration, when the mud pressure filtration is completed on the right side and the filter plate 9 moves to the left to drive the discharge baffle 71 to be fully opened, the vertical driving device 81 works to drive the upper baffle 8 to move downward. Thus, a downward force can be provided to the solidified material through the upper baffle 8. In this way, under the action of the driving force and gravity, the solidified material can fall smoothly. The setting form of the vertical driving device 81 is not limited. For example, it can be set as a driving 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 (takingFigure 9 The position of the medium-pressure filter plate 9 is the initial state):

[0088] The slurry treated by the chemical dosing unit 1 and the sedimentation unit 2 is sent to the curing box body 4 through the feed port 61. At this time, the slurry falls on the left side of the filter plate 9. While the slurry is being fed, the driving motor 104 operates, causing the filter plate 9 to move to the left. As the filter plate 9 moves to the left, the transmission plate 111 and the driving plate 116 move synchronously to the left. Under the limiting and guiding of the movement guiding groove 12, the driving plate 116 first drives the moving baffle 73 on the right side to move, making the discharge port 42 in a fully open state. At the same time, the vertical driving device 81 drives the upper baffle 8 to move downward, realizing the discharging of the solidified material on the right side. Then the driving plate 116 contracts, and the moving baffle 73 on the right side resets. The filter plate 9 moves to the feed port 61. As the filter plate 9 continues to move to the left, the slurry passing through the feed port 61 will fall on the right side reserve of the filter plate 9. The filter plate 9 presses the slurry on the left side as it continues to move to the left. At the same time, the driving plate 116 moves to the left of the moving baffle 73 on the left side under the limitation of the movement guiding groove 12. Then, the filter plate 9 moves to the right, the driving plate 116 moves, driving the moving baffle 73 on the left side to move to the right, realizing 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, realizing the discharging of the solidified material on the left side. After the driving plate 116 moves a certain distance horizontally, it gradually contracts inward until it disengages from the moving baffle 73 on the left side, and the moving baffle 73 on the left side resets, 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 press the slurry on its right side. When the filter plate 9 moves past the feed port 61, the slurry will fall on the left side reserve of the filter plate 9 again. When the filter plate 9 finishes pressing the slurry on the right side, the driving plate 116 is located on the right side of the moving baffle 73 on the right side. After that, the above process is repeated to achieve continuous treatment of the slurry.

[0089] The slurry separation and curing device of the present invention can achieve continuous treatment of the slurry. Compared with the prior art, it can realize automatic discharging of the solidified material, and the discharging method is safe and reliable, and the overall slurry separation and curing efficiency is high.

[0090] The above is only one embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. 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.
