Description

Technical Field

[0001] The present application relates to the technical field of sludge treatment, and in particular to a sludge in-situ solidification device and a construction method thereof. Background Art

[0002] In-situ sludge solidification is a method of treating contaminated soil and waste by directly treating the sludge on site to solidify it into a stable solid, thereby reducing pollution and risks to the environment. This method usually includes chemical treatment of the sludge, addition of a solidifying agent, mixing and stirring, etc., so that the sludge becomes a solid material that is not easy to penetrate and release harmful substances, thereby reducing the risk of environmental pollution.

[0003] In the related art, a Chinese invention patent with publication number CN115043558A discloses a sludge in-situ solidification device and a construction method thereof, comprising a mounting plate connected to a sludge walking device and a silo connected to the tail of the mounting plate, a slotted wheel for vertically cutting the sludge, a sprinkling box for sprinkling a curing agent, and a stirring roller for horizontally stirring the sludge are arranged at the bottom of the mounting plate, the sprinkling box is connected to the discharge end of the lower hopper on the mounting plate, the lower hopper is connected to the silo through a suction pipe, and a negative pressure fan is connected to the lower hopper, the sludge is first slotted by the slotted wheel, and then the curing agent is evenly sprinkled on the top, middle and bottom of the sludge through the slotting, and then the sludge is stirred by a horizontally rotating stirring roller so that the curing agent is evenly mixed in the sludge, and finally the stirred sludge is flattened by the silo.

[0004] Regarding the above-mentioned related technologies, when there are many large-grained stones in the silt, the larger stones will cause the silt particles to be unevenly arranged, resulting in the curing agent being unable to be evenly mixed with the silt, affecting the curing effect, and the larger stones may form weak points in the silt, reducing the overall curing strength and affecting the mechanical properties of the cured body, so improvements are made to this. Summary of the invention

[0005] In order to process larger stones in the sludge and improve the performance of the solidified sludge, the present application provides a sludge in-situ solidification device and a construction method thereof.

[0006] The present application provides a sludge in-situ solidification device and a construction method thereof, which adopts the following technical solutions:

[0007] A sludge in-situ solidification device comprises a mounting frame and a moving wheel, wherein a first filter frame, a second filter frame, a first fixed frame and a second fixed frame are further arranged on the mounting frame, wherein the first filter frame is arranged above the second filter frame, the first fixed frame is arranged between the first filter frame and the second filter frame, and the second fixed frame is arranged below the second filter frame, wherein storage bins for storing liquid solidifying agent are provided inside the first filter frame and the second filter frame, sludge vibration sieve holes are provided on the first filter frame and the second filter frame, and a liquid outlet is provided on the inner bottom wall of the storage bin, and the liquid outlet and the sludge vibration sieve holes are staggered with each other;

[0010] The mounting frame is also provided with a discharging structure for laying the silt and stone powder after the layered vibration screening in layers to form a layer structure.

[0011] By adopting the above technical scheme, when the first driving component drives the dumping component to operate, the dumping component can transfer the sludge in batches, and dump the sludge into the first filter frame and the second filter frame respectively. The first filter frame and the second filter frame can screen out larger particles of stone in the sludge, and under the action of the vibrating screen moving component, the stone can move along the length direction of the first filter frame and the second filter frame, and the vibration of the stone during the movement can reduce the amount of silt attached to the stone, improve the dryness of the stone powder after crushing, and facilitate the subsequent sprinkling of the stone powder. In the process of vibrating the sludge, the liquid curing agent stored in the storage bins opened inside the first filter frame and the second filter frame can be discharged from the liquid outlet, so as to be mixed with the sludge filtered by vibration. The second driving component in the present application can also drive the first crushing roller group and the second crushing roller group to crush and grind the vibrated stones in batches.

Since the first guide rod 22 penetrates the mounting seat 21 and is fixedly installed in the movable frame 25, and the first elastic member 27 is installed between the mounting seat 21 and the movable frame 25, the mounting seat 21 can vibrate up and down when the fan-shaped wheel 24 rotates. Since one end of the second guide rod 23 is fixed to the side wall of the movable frame 25, and the other end penetrates the fixed plate 26 and is movably connected to the fixed plate 26, the second elastic member 28 is installed between the movable frame 25 and the fixed plate 26, the mounting seat 21 can also vibrate left and right when the fan-shaped wheel 24 rotates. Therefore, through the second fixed frame 16 fixedly connected to the mounting seat 21, the first filter frame 13, the second filter frame 14, the first fixed frame 15 and the second fixed frame 16 are driven as a whole to perform an elliptical trajectory motion, thereby realizing the layered vibration screening of stones in the sludge.

[0059] The stones can also move along the length direction of the first filter frame 13 and the second filter frame 14 during the vibrating screening, and the vibration of the stones can reduce the amount of silt attached to the stones and improve the dryness of the stone powder after being crushed; in this embodiment, the first elastic member 27 and the second elastic member 28 are both springs, and the spring is a preferred method of this embodiment. In other embodiments, the first elastic member 27 and the second elastic member 28 can be elastic rubber sleeves, etc.

The stirring blade 10 can further improve the mixing degree of the sludge after vibration and the liquid curing agent, so that the sludge and the liquid curing agent are mixed more evenly, improve the consistency of the mixed sludge, thereby improving the compressive strength and accelerating the curing time, thereby improving its performance and scope of application.

[0061] In order to achieve batch treatment of sludge, Figure 3 and Figure 6 The dumping assembly 3 in this embodiment includes a mounting plate 31, a first dumping bucket 32, a second dumping bucket 33, a rotating rod 34, a gear 35, a chain 36 and a dumping structure 37.

When the second paddle 374 abuts against the second fixing plate 376, the second dumping bucket 33 is turned over to dump the sludge into the second filter frame 14, thereby realizing batch processing of the sludge.

The second transmission member in this embodiment is arranged with the first transmission member.

[0069] When the output shaft of the engine 61 rotates, the active bevel gear 71 drives the first driven bevel gear 72 to rotate through the third transmission rod 74 and the first transmission member provided on the first vertical rod 75, so as to drive the first crushing roller group 4, and crush and grind the stones transported by the first fixed frame 15.
