However, this treatment method also faces many challenges. With the continuous accumulation of silt in the deep pit, its depth gradually deepens and its area continues to expand, which brings great difficulties to the subsequent solidification treatment. Due to the large depth and area of ​​silt, traditional in-situ solidification methods often fail to achieve the desired effect. Not only is the treatment efficiency low, but also the cost is high. For this reason, we propose a new type of river silt treatment device. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a new type of river sludge treatment device, including a sludge outlet pipe 1, and also includes:

[0036] The pre-dehydration mechanism 2 is arranged at one end of the sludge outlet pipe 1 and is conductively connected thereto, and the pre-dehydration mechanism 2 is conductively connected to the external sludge extraction device, and is used to pre-dehydrate the sludge, specifically, to reduce the water content of the sludge to a level suitable for mixing with the curing agent, but not to completely dehydrate it. The sludge outlet pipe 1 is fixedly connected with a shell for protecting the main body of the equipment;

[0037] The mixing mechanism 3 is arranged in the sludge outlet pipe 1, and the mixing mechanism 3 has three levels and is arranged in sequence along the sludge flow direction. The other end of the sludge outlet pipe 1 is connected to a connecting pipe 5, and the connecting pipe 5 is connected to an external curing agent supply device, and is used to transport the curing agent into the pipe and then use the mixing mechanism 3 to fully stir and mix the sludge and the curing agent;

[0038] The intelligent unloading component 4 is arranged on the sludge outlet pipe 1 and connected to the mixing mechanism 3. Its uniqueness lies in that when the sludge and the curing agent move along the flow direction in the sludge outlet pipe 1 and are stirred and mixed by the mixing mechanism 3 in turn, the intelligent unloading component 4 can accurately identify the mixing state of the sludge and the curing agent in each level of the mixing mechanism 3. Once the preset mixing uniformity is reached, the unloading component corresponding to the mixing mechanism 3 at this level will be started immediately to discharge the mixed sludge and curing agent mixture. This feature ensures that the sludge and the curing agent can be fully mixed in each level of the mixing mechanism 3 and discharged immediately after the best mixing effect is achieved, thereby improving the overall processing efficiency and mixing quality.

[0039] The pre-dehydration mechanism 2 includes a hollow cylinder 21 which is connected to the sludge outlet pipe 1. The hollow cylinder 21 is connected to an external sludge extraction device through a conduit. The inner wall of the connecting end of the hollow cylinder 21 and the sludge outlet pipe 1 adopts a conical design, and a shaft 22 is rotatably connected inside the hollow cylinder 21. A spiral extrusion blade 23 is fixedly connected to the shaft 22. A plurality of filter holes 24 are evenly spaced on the hollow cylinder 21. A drive motor 25 is fixedly connected to one end of the hollow cylinder 21. The output shaft of the drive motor 25 is fixedly connected to the shaft 22. The drive motor 25 is started to drive the shaft 22 to rotate, and then the spiral extrusion blades 23 are used to rotate and squeeze the sludge to dehydrate it.

[0040] The mixing mechanism 3 includes three spiral conveying blades 26 equidistantly and evenly fixedly connected to the shaft 1 22 for assisting in conveying the sludge and the curing agent, and a group of stirring blades 27 are arranged on one side of the three spiral conveying blades 26 for stirring and mixing the sludge and the curing agent.

[0041] The intelligent unloading component 4 includes three discharge ports 28 evenly and equidistantly provided on one side of the sludge outlet pipe 1. The three discharge ports 28 correspond to the three groups of stirring blades 27 one by one. Three blocking plates 29 are slidably connected to the sludge outlet pipe 1 to block the three discharge ports 28. A mixture detection component 31 is provided on the sludge outlet pipe 1 to detect the degree of mixing of sludge and curing agent.

[0042] A driving assembly 32 is provided on the sludge outlet pipe 1 , and the driving assembly 32 is connected to the mixture detection assembly 31 . When the mixture detection assembly 31 detects that the sludge and the curing agent are mixed, the driving assembly 32 can be controlled to open the corresponding blocking plate 29 .

[0043] The mixture detection assembly 31 includes three injection cylinders 33 fixedly connected to the sludge outlet pipe 1, the three injection cylinders 33 correspond to the three discharge ports 28 one by one, and a piston 34 is slidably connected inside the injection cylinder 33, a tension sensor 35 is fixedly connected to one side of the piston 34, and a pull rod 36 is fixedly connected to one end of the tension sensor 35. The pull rod 36 is pulled to use the tension sensor 35 to drive the piston 34 to move to extract the mixture and detect the viscosity of the mixture. Specifically, when the sludge and the curing agent are mixed, the viscosity of the mixture formed will increase, so when the pull rod 36 is pulled to use the piston 34 to extract the mixture, the tension sensor 35 will be subjected to a certain tension, and then the size of the tension is used to determine whether the preset mixing degree is reached.

[0044] The driving assembly 32 includes an electric push rod 37 fixedly connected to the sludge outlet pipe 1, the output end of the electric push rod 37 is connected to the sealing plate 29, and a sliding rod 38 is fixedly connected to the sludge outlet pipe 1. The sliding rod 38 slides through the sealing plate 29 to guide and limit the movement of the sealing plate 29. A slide plate 39 is fixedly connected to one end of the sliding rod 38, and a guide rod 41 is fixedly connected to one side of the sealing plate 29. The guide rod 41 slides through the slide plate 39, and a transmission member 42 is arranged between the slide plate 39 and the pull rod 36. When the electric push rod 37 is started, the pull rod 36 is driven to move by the transmission member 42. When the electric push rod 37 is started again, the pull rod 36 is pushed back by the transmission member 42, and the sealing plate 29 is driven to move at the same time.

[0045] The transmission member 42 includes a rectangular plate 43 slidably connected to the sludge outlet pipe 1, and one end of the pull rod 36 is fixedly connected to an L-shaped plate 44, and one end of the L-shaped plate 44 is fixedly connected to a second shaft 45. An inverted V-shaped guide groove 46 is provided on the rectangular plate 43, and one end of the second shaft 45 is located in the guide groove 46 and slidably connected to the inner wall thereof. The moving rectangular plate 43 drives the pull rod 36 to move;

[0046] A shaft 3 47 is fixedly connected to both ends of the rectangular plate 43, a hollow rectangular frame 48 is fixedly connected to the sludge outlet pipe 1, one end of the shaft 3 47 is located in the hollow rectangular frame 48 to guide and limit the sliding of the rectangular plate 43, and a lever 49 is rotatably connected to the sludge outlet pipe 1 through a rotating shaft, and a slide groove 51 is opened at both ends of the lever 49, one end of a shaft 3 47 is located in the slide groove 51, and a shaft 4 52 is fixedly connected to the slide plate 39, and one end of the shaft 4 52 is located in the slide groove 51, and the moving slide plate 39 drives the rectangular plate 43 to move;

[0047] Specifically, in the initial state, the blocking plate 29 blocks the discharge port 28. At this time, the electric push rod 37 is started to pull the slide plate 39. In the initial movement distance of the electric push rod 37, it does not drive the blocking plate 29 to move. Specifically, the slide plate 39 slides along the guide rod 41, and at the same time, the movement of the slide plate 39 drives the lever 49 to deflect using the shaft four 52, thereby driving the rectangular plate 43 to move, so that the guide groove 46 is used to push the shaft two 45, the L-shaped plate 44, the pull rod 36, and the piston 34 to move upward to extract the mixture and use the tension sensor 35 for detection. At this time, there are two situations. One is that the mixture is mixed. At this time, the tension sensor 35 controls the electric push rod 37 through the program to continue to pull the slide plate 39, thereby driving the blocking plate 29 to open, and also using the guide groove 46 to push the piston 34 out. The second is that the mixture has not been mixed yet. At this time, the tension sensor 35 controls the electric push rod 37 to push back to the initial position, and repeats in sequence;

[0048] When the blocking plate 29 is in the open state, detection is carried out. At this time, the electric push rod 37 is started to push the slide plate 39 to move a certain distance. Similarly, the slide plate 39 will not drive the blocking plate 29 to move during the initial movement of the distance, but it will also drive the piston 34 to move up to extract the mixture for detection. At this time, there will be two situations. One is that the mixture is mixed. At this time, the tension sensor 35 controls the electric push rod 37 to pull back through the program to keep the blocking plate 29 in the open state. The second is that the mixture is not mixed. At this time, the tension sensor 35 controls the electric push rod 37 to push the slide plate 39 to continue moving, thereby pushing the blocking plate 29 to block the discharge port 28.

[0049] The end of the sludge outlet pipe 1 away from the driving motor 25 is connected to the second connecting pipe 53, and the second connecting pipe 53 is also connected to the external curing agent supply device to supply the curing agent to the last stage mixing mechanism 3;

[0050] Specifically, when the mixing mechanism 3 is working, the first stage is used for the preliminary mixing of the sludge and the curing agent. If the mixture is mixed completely at this stage, it can be discharged in time. However, if it is not mixed well after detection, the mixture will enter the second stage for simple further mixing. When the mixing is completed, it can also be discharged in time. If it still does not meet the standards after detection, it may be due to the lack of curing agent. Therefore, it will enter the third stage for mixing and stirring with additional curing agent and then be discharged.

[0051] The sludge outlet pipe 1 adopts a split design and includes a pipe body 1 54 and a pipe body 2 55. The pipe body 1 54 includes the first two-stage mixing mechanism 3, and the pipe body 2 55 contains the last-stage mixing mechanism 3. One end of the pipe body 2 55 is fixedly connected to an inner pipe 56, one end of the inner pipe 56 is located in the pipe body 2 55 and is slidably connected to its inner wall, and the pipe body 2 55 is fixedly connected to a guide rod 57, and the pipe body 1 54 is fixedly connected to a sliding sleeve 58. One end of the guide rod 57 slides through the sliding sleeve 58 and is fixedly connected to a spring 59, and one end of the spring 59 contacts and abuts against the sliding sleeve 58.

[0052] The shaft 22 is of segmented design. One end of the shaft 22 is rotatably connected to the tube body 55, and the other end is fixedly connected to a cross rod 61. One end of the other shaft 22 is provided with a cross groove 62, and one end of the cross rod 61 is located in the cross groove 62 and is slidably connected to the inner wall thereof.

[0053] Specifically, when the mixture enters the third stage, it is stirred and mixed. If the mixture is in a state of continuous entry, it will push the tube body to move and extend until the blocking plate 29 is opened. At the same time, the compression spring 59 provides it with self-restoring elastic force, thereby improving the adaptability of the device.

[0054] Example 2: Please refer to Figure 1-Figure 9 , the present invention provides a technical solution: Example 2 is optimized on the basis of Example 1;

[0055] One end of the stirring blade 27 in the second tube body 55 is fixedly connected to the fifth shaft 63, and the fifth shaft 63 is rotatably connected to the first shaft 22 through a bearing, and one side of the stirring blade 27 is fixedly connected to the sixth shaft 64, and a strip plate 65 is provided on the first shaft 22, and the strip plate 65 is rotatably connected to multiple sixth shafts 64, and the strip plate 65 is pushed to drive the stirring blade 27 to deflect and tilt;

[0056] A movable plate 66 is slidably connected to the shaft 1 22, a round rod 67 is fixedly connected to one end of the strip plate 65, and one end of the round rod 67 slides through the movable plate 66. The shaft 1 22 adopts a hollow design, and a shaft 7 68 is slidably connected inside the shaft 1 22. The shaft 7 68 is fixedly connected to the movable plate 66, and one end of the shaft 7 68 passes through the shaft 1 22 and is rotatably connected to the limit plate 69. One end of the limit plate 69 is fixedly connected to a push rod 71, and a rod body with one end sliding through the limit plate 69 is fixedly connected to the sludge outlet pipe 1, which is used to guide and limit the sliding of the limit plate 69, and the movable slide plate 39 closes the blocking plate 29 and pushes the push rod 71 to move at the same time;

[0057] During specific use, when the third-stage blocking plate 29 is in a closed state, the slide plate 39 contacts and abuts against the push rod 71 and limits it, thereby keeping the stirring blade 27 parallel to the axis 22. However, when the blocking plate 29 is in an open state, the rotation of the axis 22 drives the stirring blade 27 to rotate while rotating along the axis 64, thereby tilting and deflecting the stirring blade 27, so that when the axis 22 rotates, the stirring blade 27 can rotate and stir while pushing the mixture to promote the discharge of the mixture. When the blocking plate 29 is not opened, the stirring blade 27 does not deflect to avoid causing excessive pressure on the mixture and reducing the mixing effect.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include"-"comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process-method-article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process-method-article or device.

[0059] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
