Description

Technical Field

[0001] This invention relates to the field of environmental pollution control technology, specifically to an environmental pollution control device for backfilling construction of liquid solidified soil. Background Technology

[0002] Liquid solidification soil backfilling refers to the process of using special additives to solidify liquid soil into a hard soil mass for backfilling. The addition of a solidifying agent causes chemical or physical changes in the soil. The solidifying agent reacts with moisture and minerals in the soil to form a cementitious substance, thereby fibrousizing and cementing the loose soil, improving its strength and stability. This process transforms previously difficult-to-handle liquid soil into solidified soil with characteristics such as self-leveling, self-compacting, and hydraulic properties, facilitating construction and subsequent use.

[0003] During the backfilling of foundation trenches in various engineering projects, challenges often arise such as narrow backfill space, large backfill depth, unstable compaction quality of the backfill soil, and high requirements for backfill soil quality. In recent years, accidents involving the subsidence and damage to building drainage systems, pipelines, and access roads due to insufficiently compacted backfill soil have occurred frequently, resulting in loss of functionality. Current traditional construction techniques struggle to achieve the designed compaction coefficient at pipeline locations, with human intervention being a major factor. The inability to use mechanical compaction makes it difficult to control the compaction degree of the backfill soil, leading to the aforementioned quality problems.

[0004] Based on the aforementioned technical problems, existing technologies have also provided some solutions. For example, Chinese Patent CN117107785A discloses a self-mixing fluidized soil backfilling method. This device solves the difficulties in backfilling various underground pipelines in collapsible loess areas, and the problem of not being able to guarantee the compaction coefficient of the backfill soil. It accelerates the project progress, ensures project quality, and achieves the goal of quality assurance and efficiency. Simultaneously, the material is in a liquid state during on-site pouring, which does not generate dust pollution, achieving green environmental protection. By adding an appropriate amount of material, using self-mixing fluidized soil to replace medium and coarse sand reduces material costs and eliminates the labor costs of manual compaction of backfill soil, ensuring construction quality and reducing later maintenance costs. Furthermore, the use of local materials reduces the cost of transporting excavated soil. It also eliminates the need for backfill compaction, and the liquid state of the material during on-site pouring prevents dust pollution. It also eliminates the need for machinery, reducing diesel consumption and noise pollution, truly achieving green environmental protection. It also avoids quality and safety accidents caused by ground subsidence and cracking, reducing later maintenance costs.

[0005] However, in actual production operations, the above-mentioned device needs to be mixed during backfilling construction. During the mixing process, a lot of dust and chemical agents will be generated. The agents and dust will evaporate into the air during the mixing process, causing air pollution. Long-term inhalation will have adverse effects on human health, and will also pollute water bodies, affecting the survival and reproduction of aquatic organisms.

[0006] Therefore, an environmental pollution control device for liquid solidified soil backfilling construction is proposed here to solve the above-mentioned problems. Summary of the Invention

[0010] A spraying mechanism is provided on one side of the side support frame. The spraying mechanism includes a square bracket, two side connecting rods and two atomizing nozzles. The top of the square bracket is fixedly connected to the bottom of the square cylinder. The two side connecting rods are respectively fixed to the two sides of the square bracket. The two atomizing nozzles are respectively fixed to the two side ends of the two side connecting rods that are far apart.

[0011] The outside of the mixing drum is equipped with a cleaning mechanism, which is used to clean the inner wall of the barrier drum.

[0012] Preferably, it also includes a filtering mechanism, which includes a bottom arc-shaped hole formed on the surface of the bottom support base, and the filtering mechanism is used to filter the liquid mixture after dust settling.

[0013] Preferably, the stirring mechanism includes a motor body, a drive gear disk, and a side drive gear disk. One side of the motor body is fixedly connected to one side of the side support frame. The output shaft of the motor body is fixedly connected to one side of the drive gear disk. One side of the drive gear disk meshes with one side of the side drive gear disk. The inner side of the side drive gear disk is fixedly connected to the surface of the square cylinder. An inner drive rod is fixedly connected to the bottom of the square support frame. A stirring blade is fixedly connected to the surface of the inner drive rod.

[0014] Preferably, a liquid guide tube is fixedly connected to the top of each of the two atomizing nozzles.

[0015] Preferably, a water pump body is fixedly connected to the top of the side support frame, a water pipe body is movably connected to one side of the water pump body, and a bottom connecting pipe is fixedly connected to the bottom of the water pump body.

[0016] Preferably, side supports are fixedly connected to both sides of the square bracket, and a side cleaning brush is fixedly connected to one side of the side support, and the two side supports are symmetrically arranged along both sides of the mixing drum.

[0017] Preferably, the surface of the bottom support base is provided with a bottom through hole, the bottom end of the inner transmission rod is fixedly connected to a bottom transmission rod, the bottom end of the bottom transmission rod is fixedly connected to a bottom square plate, the bottom of the bottom square plate is movably connected to a bottom homogenizing brush, and the surface of the bottom transmission rod is disposed inside the bottom through hole.

[0018] Preferably, a bottom storage box is slidably connected to the inner side of the bottom support base, a side handle is fixedly connected to one side of the bottom storage box, and an inner filter screen is fixedly connected to the inner side of the bottom storage box.

[0019] Preferably, the top of the stirring cylinder is provided with a top connecting hole, and the inner side of the top connecting hole is disposed on the surface of the inner transmission rod.

[0020] Preferably, there are two atomizing nozzles and two liquid guide tubes, and one side of each of the two liquid guide tubes is fixedly connected to both sides of the square cylinder.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0022] 1. The rotating side drive gear disk drives the square cylinder to rotate along the top connecting hole. Through the connection of the square bracket, the rotating square cylinder drives the inner drive rod to rotate synchronously. When the inner drive rod rotates, it drives multiple stirring blades to stir along the inner side of the mixing cylinder, which can stir the liquid solidified soil. At the same time, the mixing process is protected by the barrier cylinder, which can reduce the diffusion of dust and agents generated during the mixing process and improve the mixing effect.

[0023] 2. After the water pump is started, the water pump drives the water pipe to transfer the dust-suppressing liquid in the external water tank to the bottom connecting pipe, and then sprays it downward through the bottom connecting pipe. The downward sprayed liquid will flow down along the square cylinder and enter the atomizing nozzle through the liquid guide pipes on both sides of the square cylinder. The atomizing nozzle sprays the liquid downward in an atomized form. The sprayed liquid can suppress the dust generated during the mixing in the mixing drum. At the same time, during the rotation of the square support, it will drive the side connecting rod to rotate synchronously. The rotating side connecting rod will drive the two atomizing nozzles to rotate along the top of the mixing drum. The rotating atomizing nozzle can expand the atomization area of ​​the liquid and improve the dust suppression effect of the atomizing nozzle.

[0024] 3. When dust comes into contact with liquid, a mixture is formed. This mixture adheres to the inner wall of the barrier cylinder. At this time, as the square support rotates, it will simultaneously drive the two side supports to rotate. The two side supports will rotate along the inner side of the barrier cylinder, and during the rotation, multiple side cleaning brushes will drive multiple side cleaning brushes to scrub along the inner wall of the barrier cylinder. Scrubbing the inner wall of the barrier cylinder with the side cleaning brushes can reduce the amount of mixture adhering to the inner wall of the barrier cylinder, thus improving the dust suppression effect.

[0025] 4. By continuously rotating the bottom equalization brush to contact the surface of the inner filter screen, the mixture on the surface of the inner filter screen can be quickly separated. The liquid will fall along the inner filter screen to the bottom of the bottom collection box, while the solid particles will remain on the surface of the inner filter screen for separation. By holding the side handle and pulling, the bottom collection box can be pulled out along the bottom of the bottom support. By separating the mixture after dust suppression, it is easier to process the mixture generated by dust suppression in the future, reducing the workload of operators. Attached Figure Description

[0038] A cleaning mechanism 6 is provided on the outside of the mixing drum 1. The cleaning mechanism 6 is used to clean the inner wall of the barrier drum 407.

[0039] It should be noted that the two rotating side supports 601 will rotate along the inner side of the barrier cylinder 407, and during the rotation, multiple side cleaning brushes 602 will drive the cleaning brushes 602 to clean along the inner wall of the barrier cylinder 407. By cleaning the inner wall of the barrier cylinder 407 with the side cleaning brushes 602, the amount of mixture adhering to the inner wall of the barrier cylinder 407 can be reduced, thus improving the dust suppression effect.

[0040] In this embodiment, a filter mechanism 7 is also included. The filter mechanism 7 includes a bottom arc-shaped hole 701, which is opened on the surface of the bottom support 2. The filter mechanism 7 is used to filter the liquid mixture after dust settling.

[0041] It should be noted that the liquid will fall along the inner filter screen 707 to the bottom of the bottom collection box 706, while the solid particles will remain on the surface of the inner filter screen 707 for separation. By separating the mixture after dust suppression, it is easier to process the mixture generated by dust suppression in the future, reducing the workload of operators.

[0042] In this embodiment, the stirring mechanism 4 includes a motor body 401, a drive gear 402, and a side drive gear 403. One side of the motor body 401 is fixedly connected to one side of the side support frame 3. The output shaft of the motor body 401 is fixedly connected to one side of the drive gear 402. One side of the drive gear 402 meshes with one side of the side drive gear 403. The inner side of the side drive gear 403 is fixedly connected to the surface of the square cylinder 404. An inner drive rod 405 is fixedly connected to the bottom of the square bracket 501. A stirring blade 406 is fixedly connected to the surface of the inner drive rod 405.

[0043] It should be noted that when the inner drive rod 405 rotates, it will drive multiple stirring blades 406 to stir along the inner side of the mixing drum 1, which can stir the liquid solidified soil.

[0044] In this embodiment, liquid guide tubes 504 are fixedly connected to the top of both atomizing nozzles 503.

[0045] It should be noted that the liquid is sprayed downwards in an atomized form by the atomizing nozzle 503. The sprayed liquid can suppress the dust generated during the stirring process in the mixing drum 1. At the same time, the square bracket 501 rotates synchronously, which drives the side connecting rod 502 to rotate as well. The rotating side connecting rod 502 drives the two atomizing nozzles 503 to rotate along the top of the mixing drum 1. The rotating atomizing nozzles 503 can expand the atomization area of ​​the liquid and improve the dust suppression effect of the atomizing nozzles 503.

[0046] In this embodiment, a water pump body 505 is fixedly connected to the top of the side support frame 3, a water pipe body 506 is movably connected to one side of the water pump body 505, and a bottom connecting pipe 507 is fixedly connected to the bottom of the water pump body 505.

[0047] It should be noted that the water pump body 505 drives the water pipe body 506 to transfer the dust-suppressing liquid in the external water tank to the bottom connecting pipe 507, and sprays it downward through the bottom connecting pipe 507. The downward sprayed liquid will flow down along the square cylinder 404 and enter the atomizing nozzle 503 through the liquid guide pipes 504 on both sides of the square cylinder 404.

[0048] In this embodiment, side support frames 601 are fixedly connected to both sides of the square bracket 501, and a side cleaning brush 602 is fixedly connected to one side of the side support frame 601. Both side support frames 601 are symmetrically arranged along both sides of the mixing drum 1.

[0049] It should be noted that during the rotation of the square bracket 501, the two side support brackets 601 will rotate simultaneously. The two rotating side support brackets 601 will rotate along the inner side of the barrier cylinder 407, and during the rotation, multiple side cleaning brushes 602 will be driven to brush along the inner wall of the barrier cylinder 407.

[0050] In this embodiment, a bottom through hole 702 is provided on the surface of the bottom support 2, a bottom transmission rod 703 is fixedly connected to the bottom end of the inner transmission rod 405, a bottom square plate 704 is fixedly connected to the bottom end of the bottom transmission rod 703, a bottom homogenizing brush 705 is movably connected to the bottom of the bottom square plate 704, and the surface of the bottom transmission rod 703 is disposed inside the bottom through hole 702.

[0051] It should be noted that during the rotation of the inner drive rod 405, the bottom drive rod 703 will be driven to rotate simultaneously. The rotating bottom drive rod 703 will drive the bottom square plate 704 to rotate. The rotating bottom square plate 704 will drive the bottom homogenizing brush 705 to rotate and contact the surface of the inner filter screen 707. By using the continuously rotating bottom homogenizing brush 705 to contact the surface of the inner filter screen 707, the mixture on the surface of the inner filter screen 707 can be quickly separated. The liquid will fall along the inner filter screen 707 to the bottom of the bottom collection box 706, while the solid particles will remain on the surface of the inner filter screen 707 for separation.

[0052] In this embodiment, a bottom storage box 706 is slidably connected to the inner side of the bottom support base 2, a side handle 708 is fixedly connected to one side of the bottom storage box 706, and an inner filter screen 707 is fixedly connected to the inner side of the bottom storage box 706.

[0053] It should be noted that by holding the side handle 708 and pulling the bottom storage box 706, it can be pulled out along the bottom of the bottom support 2. This separates the mixture after dust suppression, making it easier to process the mixture generated during dust suppression and reducing the workload of the operator.

[0054] In this embodiment, the top of the stirring cylinder 1 is provided with a top connecting hole 408, and the inner side of the top connecting hole 408 is disposed on the surface of the inner transmission rod 405.

[0055] It should be noted that the rotating square cylinder 404 will drive the inner transmission rod 405 to rotate synchronously. When the inner transmission rod 405 rotates, it will drive multiple stirring blades 406 to stir along the inner side of the mixing cylinder 1, which can stir the liquid solidified soil. At the same time, the mixing process is protected by the barrier cylinder 407, which can reduce the diffusion of dust and agents generated during the mixing process and improve the mixing effect.

[0056] In this embodiment, there are two atomizing nozzles 503 and two liquid guide tubes 504, and one side of each liquid guide tube 504 is fixedly connected to both sides of the square cylinder 404.

[0057] It should be noted that the liquid sprayed downward through the bottom connecting pipe 507 will flow downward along the square cylinder 404 and enter the atomizing nozzle 503 through the liquid guide pipes 504 on both sides of the square cylinder 404. The atomizing nozzle 503 will spray the liquid downward in an atomized manner, and the sprayed liquid can suppress the dust generated during the stirring in the mixing tank 1.

[0058] An environmental pollution control device for backfilling with liquid-solidified soil includes the following steps:

[0059] First, by starting the motor body 401, the motor body 401 drives the active gear disk 402 to rotate. Through the meshing of the active gear disk 402 and the side drive gear disk 403, the rotating active gear disk 402 drives the side drive gear disk 403 to rotate. The rotating side drive gear disk 403 drives the square cylinder 404 to rotate along the top connecting hole 408. Through the connection of the square bracket 501, the rotating square cylinder 404 drives the inner drive rod 405 to rotate synchronously. When the inner drive rod 405 rotates, it drives multiple stirring blades 406 to rotate along the stirring cylinder 1. The internal mixing mechanism effectively agitates the liquid-solidified soil. During mixing, a barrier cylinder 407 provides protection, reducing the spread of dust and chemicals and improving mixing efficiency. Simultaneously, as the square cylinder 404 rotates, the water pump 505 drives the water pipe 506 to transfer the dust-suppressing liquid from the external water tank to the bottom connecting pipe 507. The liquid is then sprayed downwards through the bottom connecting pipe 507, flowing down the square cylinder 404 and... Liquid guide pipes 504 on both sides of the square cylinder 404 enter the atomizing nozzle 503. The atomizing nozzle 503 atomizes the liquid and sprays it downwards. The sprayed liquid can suppress dust generated during stirring in the mixing drum 1. Simultaneously, as the square support 501 rotates, it synchronously drives the side connecting rod 502 to rotate. The rotating side connecting rod 502 drives the two atomizing nozzles 503 to rotate along the top of the mixing drum 1. The rotating atomizing nozzles 503 can expand the atomization area of ​​the liquid, improving the dust suppression effect. During the process, dust and liquid come into contact and form a mixture, which adheres to the inner wall of the barrier cylinder 407. At this time, as the square bracket 501 rotates, it will simultaneously drive the two side support frames 601 to rotate. The two rotating side support frames 601 will rotate along the inner side of the barrier cylinder 407, and during the rotation, they will drive multiple side cleaning brushes 602 to brush along the inner wall of the barrier cylinder 407. By brushing the inner wall of the barrier cylinder 407 with the side cleaning brushes 602, the amount of mixture adhering to the inner wall of the barrier cylinder 407 can be reduced, thus improving the dust suppression effect.After the atomizing nozzle 503 sprays liquid to suppress dust, and simultaneously the side cleaning brush 602 washes the mixture from the air and the inner wall of the barrier cylinder 407, the mixture falls onto the surface of the bottom support 2 and flows downward through the bottom arc-shaped hole 701 into the bottom collection box 706. After entering the inner side of the bottom collection box 706, the mixture settles on the surface of the inner filter screen 707. During the rotation of the inner drive rod 405, the bottom drive rod 703 is simultaneously driven to rotate. The rotating bottom drive rod 703 drives the bottom square plate 704 to rotate, and the rotating bottom square plate 704 drives the bottom homogenizing brush 705 along the inner... The surface of the filter screen 707 is subjected to rotating contact, and the continuously rotating bottom homogenizing brush 705 contacts the surface of the inner filter screen 707, which can quickly separate the mixture on the surface of the inner filter screen 707. Liquid will fall along the inner filter screen 707 to the bottom of the bottom collection box 706, while solid particles will remain on the surface of the inner filter screen 707 for separation. By holding the side handle 708 and pulling, the bottom collection box 706 can be pulled out along the bottom of the bottom support 2. By separating the mixture after dust suppression, it is easier to process the mixture generated during dust suppression, reducing the workload of operators.

[0060] It should be noted that the motor body 401 and the water pump body 505 in this invention are both existing technologies, and the corresponding models can be selected according to actual needs. The internal structure and operating principle of the above-mentioned parts are also common knowledge to those skilled in the art, and will not be elaborated on further.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
