Description

Technical Field

[0001] This invention relates to the field of deep in-situ mixing technology for silt, specifically to a deep in-situ mixing device for marine silt. Background Technology

[0002] The marine sludge in-situ mixing device is an engineering equipment specifically designed for sludge solidification treatment and belongs to the category of excavator special tools. Its core function is to achieve uniform mixing of sludge and solidifying agent through mechanical agitation, allowing the sludge to undergo physicochemical changes in situ (without migrating), ultimately forming a stable, high-bearing-capacity solidified soil layer. This equipment is directly installed at the front end of the excavator, utilizing the excavator's hydraulic power and mobility to complete operations in complex terrains (such as river channels, soft soil foundations, and landfills).

[0003] The existing deep mixing device for marine silt consists of a powerful mixing head, an excavator carrier, a material supply control system, and a solidifying agent storage tank. The powerful mixing head mixes the silt through a mixing drum and external mixing blades, while simultaneously ensuring that the solidifying agent is fully mixed into the silt.

[0004] Because the silt contains hard impurities such as fragments, the mixing blades will wear down during the mixing process. If the mixing blades are not replaced in time, the mixing resistance will increase, and the hardener will not mix evenly with the silt, resulting in areas of insufficient or excessive hardening, which will affect the strength and stability of the solidified soil layer. The existing mixing head is inconvenient to install and disassemble. The disassembly of the mixing drum is complicated and requires professional tools and multiple people to work together. The maintenance time for a single maintenance may be extended from several hours to several days, resulting in delays in the project schedule. Therefore, we propose a deep in-situ mixing device for marine silt. Summary of the Invention

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figures 1 to 2 A deep in-situ mixing device for marine silt includes a connecting seat 1, which is mounted on an excavator. A mixing arm 2 is mounted on the connecting seat 1, and a curing agent feed pipe is mounted on the mixing arm 2. Two connecting ends 3 are also provided at one end of the mixing arm 2. A hydraulic rotating mechanism 31 is provided inside the connecting end 3, and a rotating shaft 32 is fixedly connected to the output end of the hydraulic rotating mechanism 31. In this application, the hydraulic rotating mechanism 31 is an existing mechanism, such as a hydraulic motor, which drives the rotating shaft 32 by running the hydraulic motor.

[0042] One end of the connecting end 3 is connected to a fixed inner cylinder 4. That is, in this application, both ends of the connecting end 3 are open. The fixed inner cylinder 4 is quickly connected to the connecting end 3 through the open mounting port of the connecting end 3.

[0043] One end of the fixed inner cylinder 4 is fixedly connected to the rotating outer cylinder 41. Multiple stirring blades 411 are installed on the outside of the rotating outer cylinder 41, and the fixed inner cylinder 4 is sleeved on the outside of one end of the connecting end 3.

[0044] Please see Figures 2 to 10 The outer side of the connecting end 3 is provided with a liquid pushing mechanism 5, and the connecting end 3 is provided with multiple moving ports 33. The inner side of the connecting end 3 is provided with a synchronous locking mechanism 6. The synchronous locking mechanism 6 is connected to the liquid pushing mechanism 5 through multiple moving ports 33, and the synchronous locking mechanism 6 can detachably fix the inner cylinder 4.

[0045] A retaining mechanism 7 is provided on the outer side of the stirring arm 2 near the connecting seat 1. The retaining mechanism 7 is used to synchronously drive the two liquid pushing mechanisms 5.

[0046] The liquid pushing mechanism 5 includes an annular sealing cylinder 51, an annular moving plug 52, a pushing retaining ring 53, a squeezing pushing member 54, and a clamping member 55. The annular sealing cylinder 51 is fixedly installed on the outside of the connecting end 3, and one end of the liquid pushing mechanism 5 is connected to the annular sealing cylinder 51. The annular moving plug 52 is connected to the inside of the annular sealing cylinder 51.

[0047] One end of the push retaining ring 53 passes through the annular sealing cylinder 51 and is fixedly connected to the annular moving plug 52. The push retaining ring 53 is slidably connected to the annular sealing cylinder 51, and the other end of the push retaining ring 53 is connected to the extrusion pusher 54. The extrusion pusher 54 is located on the outside of the connecting end 3.

[0048] The connecting end 3 is provided with multiple locking holes 34, and the clamping member 55 is located at multiple locking holes 34.

[0049] The extrusion pusher 54 includes a first pusher baffle 541, a connecting pusher plate 542, a second pusher baffle 543, and an extrusion block 544. One end of the pusher retaining ring 53 is fixedly connected to the first pusher baffle 541. Multiple connecting pushers 542 are provided. One end of the multiple connecting pushers 542 is fixedly connected to the first pusher baffle 541, and the other end of the multiple connecting pushers 542 is fixedly connected to the second pusher baffle 543.

[0050] In this application, there is a certain friction between the ring-shaped extrusion block 544 and the connecting end 3. At the same time, the extrusion block 544 can also be provided with anti-slip texture. The extrusion block 544 and the connecting end 3 can be connected by a relatively mating connection method. That is, only when the first push baffle 541 or the second push baffle 543 contacts the extrusion block 544 and pushes the extrusion block 544 can the extrusion block 544 move relative to the outside of the connecting end 3.

[0051] A support spring 545 is provided on the outside of the connecting push plate 542, and the two ends of the support spring 545 are fixedly connected to the first push baffle 541 and the annular sealing cylinder 51 respectively.

[0052] The extrusion block 544 is ring-shaped and is slidably sleeved on the outside of the connecting end 3. The extrusion block 544 is provided with multiple connecting ports 5441, and the connecting push plate 542 slides through the connecting ports 5441.

[0053] The inner side of the extrusion block 544 is provided with an inclined extrusion section 546 and a transverse positioning section 547, and the extrusion block 544 extrudes the clamping member 55 in sequence through the inclined extrusion section 546 and the transverse positioning section 547.

[0054] The clamping component 55 includes clamping balls 551, and multiple clamping balls 551 are provided. The multiple clamping balls 551 are located at multiple locking holes 34 respectively. An annular outer groove 42 is provided on the outer side of the fixed inner cylinder 4. The multiple clamping balls 551 are engaged with the annular outer groove 42, and the transverse positioning section 547 of the extrusion block 544 positions the multiple clamping balls 551.

[0055] As a further supplementary explanation, the fixing mechanism 7 includes a liquid storage tube 71, a push piston 72, a push rod 73, a rotating support rod 74, a positioning shaft 75, an electric push rod 76, and a cross rod 77. There are two liquid storage tubes 71, which are respectively fixedly installed on both sides of the outside of the stirring arm 2. The bottom of the liquid storage tube 71 is connected to the adjacent annular sealing cylinder 51. The push piston 72 is connected to the top of the inner wall of the liquid storage tube 71. The push rod 73 slides through the top of the liquid storage tube 71. The bottom of the push rod 73 is fixedly connected to the push piston 72. A cross plate 78 is fixedly connected to the top of the push rod 73. A horizontal opening 781 is provided on the cross plate 78. A fixed shaft slides through the horizontal opening 781. The two ends of the fixed shaft are fixedly connected to one end of the rotating support rod 74.

[0056] One end of the positioning shaft 75 is fixedly connected to the stirring arm 2, and the rotating support rod 74 is rotatably sleeved on the outside of the positioning shaft 75;

[0057] The two ends of the crossbar 77 are fixedly connected to two rotating support rods 74. The electric push rod 76 is rotatably connected to the outside of the stirring arm 2 through the hinge support, and the output end of the electric push rod 76 is rotatably connected to the crossbar 77.

[0058] In this application, an electric push rod 76 or a non-electrically driven method such as fixing bolts can be used to fix the crossbar 77 at different positions. The electric push rod 76 is installed on the top of the stirring arm 2 to prevent sludge from adhering to the electric push rod 76.

[0059] Specific implementation process: In this application, the closed cavity between the liquid storage tube 71 and the annular sealing cylinder 51 is filled with hydraulic oil. When installing the fixed inner cylinder 4 and the rotating outer cylinder 41, one end of the fixed inner cylinder 4 is first inserted into the connecting end 3, and the rotating outer cylinder 41 is sleeved on the outside of the connecting end 3. Then, the electric push rod 76 is operated, which further causes the crossbar 77 to drive the two rotating support rods 74 to rotate around the positioning shaft 75. When the rotating support rods 74 rotate, the push rod 73 is pushed through the horizontal opening 781 on the cross plate 78. The push rod 73 then drives the push piston 72 to move downward relative to the liquid storage tube 71, so that the hydraulic oil continuously enters the annular sealing cylinder 51.

[0060] At this time, the annular sealing cylinder 51 pushes the annular moving plug 52 with hydraulic oil. The annular moving plug 52 drives the first pushing baffle 541 to move through the pushing retaining ring 53. The first pushing baffle 541 then drives the extrusion block 544 to move along the outside of the connecting end 3. The inclined extrusion section 546 of the extrusion block 544 passes through multiple clamping balls 551 in sequence until the transverse positioning section 547 moves to the clamping ball 551. The multiple clamping balls 551 are then clamped in the annular outer groove 42 of the fixed inner cylinder 4. At the same time, with the setting of clamping balls 551, when the fixed inner cylinder 4 rotates relative to the connecting end 3, the clamping balls 551 can reduce the rotational resistance of the fixed inner cylinder 4.

[0061] Please see Figures 1 to 3 The synchronous locking mechanism 6 includes a moving rod 61, a moving plate 62, a moving sleeve 63, and a locking plate 64. Multiple moving rods 61 are provided, and the multiple moving rods 61 slide through the moving opening 33 respectively. The multiple moving rods 61 are fixedly connected to the moving plate 62. The moving plate 62 is rotatably sleeved on the outside of the moving sleeve 63. The moving sleeve 63 is slidably sleeved on the outside of the rotating shaft 32. A limiting member 65 is provided between the moving sleeve 63 and the rotating shaft 32. In this application, the limiting member 65 consists of two limiting strips 651 fixedly installed on the outside of the rotating shaft 32. At the same time, the moving sleeve 63 is provided with a groove corresponding to the position of the limiting strips 651, and the moving sleeve 63 is slidably sleeved on the outside of the two limiting strips 651 through the groove.

[0062] Multiple locking plates 64 are provided, and multiple locking plates 64 lock the fixed inner cylinder 4. Each locking plate 64 is connected to the movable sleeve 63 and the rotating shaft 32 by a connecting piece 66.

[0063] The locking plate 64 has a fixing protrusion 641 on the side near the fixed inner cylinder 4, and the fixed inner cylinder 4 has a limiting outer edge at one end.

[0064] As a further supplementary explanation, the connector 66 includes a first connecting rod 661 and a second connecting rod 662. One end of the first connecting rod 661 is rotatably connected to the locking plate 64 through a hinge support, and the other end of the first connecting rod 661 is rotatably connected to the movable sleeve 63 through a hinge support.

[0065] The locking plate 64 is also provided with a guide port 642, and a guide shaft 663 slides through the guide port 642. The guide shaft 663 is fixedly connected to the second connecting support rod 662. The other end of the second connecting support rod 662 is rotatably connected to the rotating shaft 32 through a hinge support. The first connecting support rod 661 and the second connecting support rod 662 are cross-connected, and the first connecting support rod 661 and the second connecting support rod 662 are hinged to each other by a pin.

[0066] Specific implementation process: When the extrusion block 544 moves relative to the outside of the connecting end 3, it simultaneously drives multiple moving rods 61 to move. The multiple moving rods 61 drive the moving sleeve 63 to move relative to the outside of the rotating shaft 32 through the moving plate 62. When the moving sleeve 63 moves, one end of the first connecting support rod 661 moves and rotates. At the same time, due to the limiting effect of the second connecting support rod 662, the locking plate 64 moves along the inner wall of the fixed inner cylinder 4.

[0067] Until the squeezing block 544 stops moving under the limiting action of the protrusion on the outside of the connecting end 3 and the first pushing baffle 541, the multiple locking plates 64 synchronously fix the inner cylinder 4 through the fixing protrusion 641.

[0068] Furthermore, as the rotating shaft 32 rotates, the moving sleeve 63 is driven to rotate synchronously through the limiting strip 651, and further driven to rotate through multiple locking plates 64, thereby achieving the effect of deep stirring of marine silt.

[0069] Furthermore, when the rotating outer cylinder 41 and the stirring blades 411 on its outer side are disassembled, the electric push rod 76 is retracted, which further enables the quick disassembly of the fixed inner cylinder 4 and the rotating outer cylinder 41.

[0070] Example 2

[0071] Please see Figures 7 to 9Example 2 is a further supplement to Example 1. Specifically, an annular spray sleeve 8 is fixedly installed on the outside of the annular sealing cylinder 51. The spray sleeve 8 has multiple spray holes 81 at one end near the rotating outer cylinder 41, and a closing member 82 is provided at the spray hole 81. The multiple closing members 82 are connected to each other by a synchronous collar 83. The synchronous collar 83 is sleeved on the outside of the connecting end 3, and one end of the synchronous collar 83 extends to the outside of the second push baffle 543.

[0072] A connecting spring 84 is also sleeved on the outside of the annular sealing cylinder 51, and the two ends of the connecting spring 84 are fixedly connected to the annular sealing cylinder 51 and the spray sleeve 8, respectively.

[0073] The closing element 82 includes a closing rod 821, a synchronization plate 822, and a synchronization rod 823. One end of the closing rod 821 is connected to the spray hole 81, and the other end of the closing rod 821 is located inside the spray sleeve 8 and is fixedly connected to the synchronization plate 822. The synchronization rod 823 slides through one side of the spray sleeve 8 and is connected to the spray sleeve 8. The two ends of the synchronization rod 823 are fixedly connected to the synchronization plate 822 and the synchronization collar 83, respectively.

[0074] The spray sleeve 8 is provided with a closing groove 85 at one end near the rotating outer cylinder 41, and two sealing rubber rings 86 are provided on the inner side of the closing groove 85. One end of the rotating outer cylinder 41 is rotatably connected to the closing groove 85.

[0075] Both spray sleeves are connected to a liquid supply pipe at 8 points, and a liquid supply pump is installed at the liquid supply pipe. A liquid supply tank is connected to the liquid supply pump. In this application, a receiving cavity is also provided inside the rotating arm, and the liquid supply pump and the liquid supply tank are installed inside the receiving cavity.

[0076] Specific implementation process: In this application, when the rotating outer cylinder 41 and the stirring blade 411 are disassembled, the second pushing baffle 543 first disengages from one end of the synchronous collar 83, and the second pushing baffle 543 moves along the direction of the extrusion block 544 along with the connecting pushing plate 542 until the second pushing baffle 543 contacts one side of the extrusion block 544 and pushes the extrusion block 544 to move;

[0077] When the second push baffle 543 disengages from one end of the synchronizing ring 83, the synchronizing ring 83 moves along the direction of the spray sleeve 8 under the reverse elastic force of the connecting spring 84. This causes multiple synchronizing rods 823 to drive the closing rod 821 to disengage from the spray hole 81 through the synchronizing plate 822. At this time, the liquid supply pump operates, causing the cleaning liquid to be sprayed out through multiple spray holes 81, thereby cleaning the outside of the rotating outer cylinder 41 and facilitating the disengagement of the rotating outer cylinder 41 from the outside of the connecting end 3. In addition, in this application, when there is a lot of sludge on the outside of the rotating outer cylinder 41, the second push baffle 543 can also be moved to the squeezing block 544 and stop moving. At this time, the spray hole 81 is in the open state, thereby spraying and cleaning the sludge on the outside of the rotating outer cylinder 41.

[0078] When the rotating outer cylinder 41 and the connecting end 3 are installed and fixed, multiple closing rods 821 simultaneously close the spray hole 81, thus protecting the spray hole 81.
