Description

Technical Field

[0001] This utility model relates to the field of soil ecological restoration equipment technology, specifically a soil ecological restoration device that avoids dust. Background Technology

[0002] Soil ecological remediation devices are specialized equipment for addressing soil pollution. They can degrade or remove heavy metals, organic pollutants, and other pollutants from the soil through physical, chemical, and biological technologies, thereby restoring the soil's ecological functions. They are widely used in scenarios such as mine remediation and contaminated site treatment. In existing technologies, such equipment has been developed into mobile and automated continuous operation types. The core structure typically includes soil collection and turning components, remediation liquid spraying mechanism, screening device, material conveying channel, and power drive system. Some equipment improves transportation flexibility through disassembly design, or enhances the uniformity of mixing between the remediation agent and the soil through spiral blades and mixing mechanisms.

[0003] The screening and material conveying processes of existing soil ecological restoration devices are mostly open structures. There is no effective sealing or shielding during the soil falling and transfer process, which leads to dust diffusion and environmental pollution. Soil particles are easily spilled out and dust is generated. Although some equipment is equipped with spraying or simple dust removal structures, the sprayed moisture is easily lost quickly for dry soil, and the dust reduction effect lasts for a short time. Utility Model Content

[0004] The purpose of this utility model is to provide a soil ecological restoration device that avoids dust, in order to solve the problems mentioned in the background art, which are mostly open structures in the screening and material conveying links, without effective sealing and shielding during soil falling and transfer, resulting in dust diffusion and environmental pollution, and easily causing soil particles to overflow and generate dust. In addition, although some equipment is equipped with spraying or simple dust removal structures, for dry soil, the sprayed moisture is easily lost quickly, and the dust reduction effect has a short duration.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil ecological restoration device that avoids dust, comprising a treatment box, which is a hollow cavity structure with an open top, the top opening of the treatment box is covered with a protective cover, and the treatment box and the protective cover together form a closed shell structure for soil restoration treatment. The processing box is embedded in the side wall and connected to a guide box. A pull-out separation frame is slidably connected in the vertical mounting groove of the guide box. Separation rods are fixed at equal intervals on the inner wall of the separation frame, and the top of the separation rods is conical. A sealed conveyor belt is installed below the opening of the vertical mounting slot of the guide box, and the sealed conveyor belt is installed at an angle inside the processing box. The raised end of the sealed conveyor belt is directly above the remediation soil recycling box, and the remediation soil recycling box is slidably connected to one end of the processing box. A remediation agent spray head is installed directly above the remediation soil recycling box, and the remediation agent spray head is installed on the inner wall of the protective cover. A remediation agent storage box is installed at the top of the protective cover, and the remediation agent storage box is connected to the remediation agent spray head through a pipe.

[0006] Using the above technical solution, the treatment box and protective cover form a closed shell, which, together with the guide box and sealed conveyor belt, forms a fully enclosed space to block the spread of dust. The further pointed cone-shaped separation rod achieves efficient soil loosening, and the remediation agent spray head works with the recycling box to complete the remediation and recycling, realizing the integration of screening, conveying, and remediation with dust control effect.

[0007] Preferably, a sealing element is provided at the connection between the processing box and the protective cover, and the protective cover is made of transparent acrylic material.

[0008] By adopting the above technical solution, the sealing element at the connection enhances the sealing performance of the shell and further prevents dust leakage. The transparent acrylic protective cover allows for real-time observation of the internal working conditions, balancing dust control and ease of operation.

[0009] Preferably, the upper end face of the guide box is provided with a connected inlet hopper, and the inlet hopper penetrates the protective cover.

[0010] By adopting the above technical solution, the hopper is introduced through the protective cover and connected to the guide box to form a closed feeding channel, thus avoiding dust from the feeding process.

[0011] Preferably, the bottom opening of the guide box is an inclined structure adapted to a sealed conveyor belt, and the motor end of the sealed conveyor belt is installed through the side wall of the processing box, and an interceptor is installed on one side of the bottom of the inclined opening of the guide box.

[0012] By adopting the above technical solution, the inclined surface at the bottom of the guide box is adapted to a sealed conveyor belt to ensure that the soil falls smoothly and reduce dust.

[0013] Preferably, the sliding structure of the separating pull-out bracket is provided by a guide rail set on the inner wall of the vertical mounting groove of the guide box.

[0014] The above technical solution ensures smooth sliding of the separation pull-out frame via the guide rail, facilitating maintenance; at the same time, it guarantees a sealed screening space, reducing dust diffusion.

[0015] Preferably, an interceptor frame 2 is provided on the side of the top of the opening of the soil remediation recycling bin near the sealed conveyor belt, and an electric rotating table is installed inside the soil remediation recycling bin.

[0016] Using the above technical solution, the second interceptor can achieve secondary interception of debris, thereby controlling the degree of dust. The electric rotating table stirs the soil, making the remediation agent evenly mixed, preventing compaction and extending the dust reduction time.

[0017] Preferably, the electric rotary table includes an electrically driven rotary table installed inside the remediation soil recycling bin and a trapezoidal plate fixed to the surface of the electrically driven rotary table.

[0018] Using the above technical solution, the electric drive turntable provides stable power, and the trapezoidal plate expands the mixing contact area, enhances the mixing effect of soil and remediation agent, and improves remediation and dust reduction efficiency.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the soil ecological restoration device that avoids dust: 1. The processing box and the protective cover are closed together to form a closed shell. The seal at the connection between the two further enhances the sealing performance and prevents dust leakage from the shell gaps. The guide box is connected to the side wall of the processing box by an embedded snap-fit ​​method. With the structure of the inlet hopper penetrating through the protective cover, the soil can directly enter the device from the outside through the closed channel, preventing dust from overflowing during the feeding stage. During the screening process, the separation pull frame is slidably assembled in the vertical installation groove of the guide box to form a semi-closed screening space. The dust generated when the pointed cone-shaped separation rod loosens the soil is confined inside the guide box. The sealed conveyor belt in the conveying stage blocks the transfer dust through the fully enclosed shell, effectively reducing soil particle overflow pollution. 2. The combination structure of the guide box and the separation pull-out frame allows the screening process to be completed in a semi-enclosed space. The two sides of the separation pull-out frame slide with the vertical mounting groove of the guide box through guide rails. The pull-out structure improves the convenience of maintenance and ensures the airtightness of the screening space, reducing the dust diffusion path. The pointed cone structure at the top of the separation rod can efficiently break up soil clumps. The equidistant distribution ensures full contact between the soil and the separation rod, improving the efficiency of loose screening. The inclined structure of the sealed conveyor belt at the bottom of the guide box, together with the first interceptor frame at the opening, can guide the soil falling after screening. At the same time, the interceptor frame slows down the falling speed of the soil and reduces the dust generated by the falling impact. The second interceptor frame at the opening of the soil recycling box further realizes secondary impurity interception and dust control, forming a graded dust control barrier. 3. The remediation agent spray nozzles installed on the inner wall of the protective cover are aligned with the sealed conveyor belt. By raising the soil falling path between the remediation soil recovery box and the remediation soil, the remediation agent is directly sprayed onto the surface of the soil to be recovered. The remediation agent storage box is connected to the spray nozzles through pipes to ensure a stable supply of remediation agent. The electric rotating table inside the remediation soil recovery box drives the surface trapezoidal plate to rotate, stirring the soil after the remediation agent is sprayed. This ensures that the remediation agent and the dry soil are fully mixed, preventing the rapid loss of moisture from the remediation agent, extending the dust suppression duration, and improving the reaction efficiency between the soil and the remediation agent. Furthermore, the remediation soil recovery box has a pull-out structure that can be sealed and pulled out after the remediation is completed. Attached Figure Description

Then, cover the top opening of the treatment box 1 with the protective cover 2, install a seal at the connection between the two, and lock and fix it with fasteners to form a closed soil remediation treatment shell structure. The protective cover 2 is made of transparent acrylic material, which makes it easy to observe the internal working conditions. The guide box 4 is embedded and snapped into the preset installation position on the side wall of the treatment box 1 to ensure a tight connection; the guide rail is fixed in the inner wall of the vertical installation groove of the guide box 4, and the separation pull-out frame 5 equipped with the separation rod 6 is slid into the guide rail so that the separation pull-out frame 5 can be pulled out flexibly and the frame edge is in contact with the inner wall of the guide box 4. The inlet bucket 3 is installed at the communication port on the upper end face of the guide box 4, ensuring that the inlet bucket 3 penetrates the preset through hole of the protective cover 2 to achieve a sealed connection of the soil inlet channel; The sealed conveyor belt 8 is installed at an angle inside the treatment box 1, with its position corresponding to the bottom opening of the guide box 4. The motor end of the sealed conveyor belt 8 passes through the side wall of the treatment box 1 and is fixed. An interceptor frame 7 is installed on one side of the bottom opening of the inclined surface of the guide box 4. The remediation soil recovery box 9 is slidably inserted into one end of the treatment box 1, with its opening facing the raised end of the sealed conveyor belt 8. An interceptor frame 10 is installed on the top of the opening of the remediation soil recovery box 9 near the sealed conveyor belt 8. An electric rotating platform 11 is fixed inside the recovery box. The electric rotating platform 11 includes an electrically driven rotating platform and a trapezoidal plate fixed on the surface. The remediation agent storage box 12 is installed on the top of the protective cover 2. The remediation agent spray head 13 is fixed on the inner wall of the protective cover 2 and located directly above the remediation soil recovery box 9. The remediation agent storage box 12 and the remediation agent spray head 13 are connected through a pipe. The reliability of each sealing connection and pipe connection is checked. The upper surface of the guide box 4 is provided with a connected inlet hopper 3, which penetrates the protective cover 2. The bottom opening of the guide box 4 is an inclined structure adapted to the sealed conveyor belt 8, and the motor end of the sealed conveyor belt 8 penetrates the side wall of the processing box 1. An interceptor frame 7 is installed on one side of the bottom inclined opening of the guide box 4. The sealed conveyor belt 8 is located below the opening of the vertical mounting slot of the guide box 4, and the sealed conveyor belt 8 is installed at an angle inside the processing box 1. The raised end of the sealed conveyor belt 8 is directly above the remediation soil recovery box 9, and the remediation soil recovery box 9 is a pull-out sliding connection. Inside the processing box 1, a remediation agent spray head 13 is installed directly above the remediation soil recycling box 9. The remediation agent spray head 13 is installed on the inner wall of the protective cover 2. A remediation agent storage box 12 is installed at the top of the protective cover 2. The remediation agent storage box 12 is connected to the remediation agent spray head 13 through a pipe. An interceptor frame 10 is installed on the side of the top opening of the remediation soil recycling box 9 near the sealed conveyor belt 8. An electric rotating table 11 is installed inside the remediation soil recycling box 9. The electric rotating table 11 includes an electric drive turntable installed inside the remediation soil recycling box 9 and a trapezoidal plate fixed on the surface of the electric drive turntable. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the soil to be repaired is fed into the inlet hopper 3. The soil is guided by the inlet hopper 3, passes through the protective cover 2 and enters the guide box 4, and finally falls into the separation pull-out frame 5. The closed structure effectively prevents dust from overflowing during feeding. The soil comes into contact with the equally spaced, cone-shaped separation rods 6 inside the separation pull-out frame 5. The clumps of soil are broken up by the separation rods 6, achieving uniform loosening. This process is completed in the semi-enclosed space formed by the guide box 4 and the separation pull-out frame 5 to prevent dust from spreading. The loosened soil falls from the separation pull-out frame 5 onto the surface of the sealed conveyor belt 8. The bottom of the guide box 4 is adapted to the inclined structure of the sealed conveyor belt 8 to ensure that the soil slides down smoothly. When the sealed conveyor belt 8 is tilted to transport the soil, the first interceptor frame 7 intercepts large impurities, and the sealing structure blocks dust during the transportation process. The soil is transported to the upper part of the sealed conveyor belt 8. When it reaches the top of the soil recovery box 9, the repair liquid in the repair agent storage box 12 is transported to the repair agent spray head 13 through the pipeline. The spray head sprays the repair liquid evenly onto the soil, and the second interceptor frame 10 performs secondary impurity interception on the soil. The soil sprayed with the remediation solution falls into the remediation soil recycling bin 9. The electric rotating table 11 is started, and the electric-driven rotating table drives the trapezoidal plate to rotate, stirring the soil to fully mix the remediation solution and prevent the soil from compacting. After the remediation is completed, the remediated soil can be removed by pulling out the remediation soil recycling bin 9.

[0024] Working principle: When using this dust-avoiding soil ecological restoration device, the soil to be restored is fed into the inlet hopper 3, passes through the protective cover 2 and enters the separation pull-out frame 5 in the guide box 4. The seal at the connection between the treatment box 1 and the protective cover 2 blocks the dust from being fed in. The separation pull-out frame 5 is stably supported by the guide box 4 and the guide rail. The pointed cone-shaped separation rod 6 inside the frame breaks up the soil clumps and achieves uniform loosening. The process is completed in a semi-enclosed space to avoid dust diffusion. The loose soil falls into the inclined sealed conveyor belt 8. The inclined structure at the bottom of the guide box 4 ensures a smooth slide. The interceptor frame 7 intercepts large impurities. The sealed conveyor belt prevents dust from being generated during transportation. The motor end passes through the processing box 1 to provide power. When the soil is transported to the top of the remediation soil recycling box 9, the remediation agent storage box 12 supplies liquid to the remediation agent spray head 13 through the pipeline. The spray head sprays the liquid evenly, and the interception frame 2 10 performs secondary impurity interception. After the soil falls into the remediation soil recycling box 9, the electric drive turntable of the electric rotating table 11 drives the trapezoidal plate to rotate, which promotes the mixing of the remediation liquid and prevents the soil from compacting. The recycling box has a pull-out design for easy material retrieval. The whole process is enclosed to achieve dust control and increase the overall practicality.
