Technical Field
[0001] This utility model relates to the field of soil remediation, and in particular to a remediation box for soil remediation. Background Technology
[0002] With the acceleration of industrialization and the increasing frequency of human activities, soil pollution has become a more and more serious problem. Metal pollutants in soil come from a wide range of sources, including industrial waste emissions, mining, the irrational use of pesticides and fertilizers in agricultural production, and urban landfill. The accumulation of these metal pollutants in the soil not only severely damages its physical, chemical, and biological properties, leading to decreased soil fertility, hardening, and affecting crop growth and yield, but also enters the human body through the food chain, endangering human health and posing a significant threat to the ecological environment and human survival.
[0003] Currently, numerous technologies exist for soil remediation, among which physical remediation methods hold a significant position in practical applications due to their relative simplicity and intuitive remediation effects. However, existing physical soil remediation equipment still faces several unresolved issues when treating metal pollutants in soil. Firstly, traditional equipment has low efficiency in separating metals from soil. Soil composition is complex, and metals are often tightly bound to soil particles, making it difficult for existing remediation equipment to efficiently separate metals from the soil. This results in high residual metal levels in the treated soil, failing to meet increasingly stringent environmental standards. Secondly, most equipment lacks targeted separation mechanisms for different types and sizes of metal particles during processing. Different metals exhibit varying physical properties, such as density and magnetism. A uniform treatment method cannot achieve precise separation of various metals, leading to inconsistent soil quality after remediation. Furthermore, existing equipment suffers from low work efficiency. Some equipment requires significant manual intervention; for example, after metal separation, manual cleaning of the conveyor belt is necessary. This not only consumes manpower and resources but also significantly reduces work efficiency and increases remediation costs. Moreover, traditional equipment has poor versatility and adaptability, and often cannot effectively treat contaminated soil from different sources and with different properties. When processing large clumps of soil, some equipment fails to achieve good metal separation because the soil clumps obstruct the contact between the metal and the separation components. Furthermore, large clumps of soil can easily clog the internal filters of the equipment, affecting its normal operation and increasing the difficulty and cost of equipment maintenance. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model discloses a soil remediation box that can efficiently separate metals from soil, improve work efficiency, enhance equipment versatility and adaptability, and is easy to maintain.
[0005] This utility model discloses a soil remediation box, which includes a box body, a through-feed inlet at the top of the box body, a hollow conveying cavity below the inlet of the box body, a hollow separation cavity on one side of the conveying cavity, the conveying cavity and the separation cavity being separated by a partition plate, a soil discharge pipe through the side of the box body near the lower part of the conveying cavity, a screening port through the side of the partition plate near the upper part, a track and a conveyor belt on the track in the separation cavity, a magnetic suction part corresponding to the screening port in the side of the separation cavity of the box body away from the screening port, and a metal discharge pipe through the lower part of the separation cavity of the box body.
[0006] The motor is located on one side of the outside of the enclosure and passes through the enclosure to connect to the rail;
[0007] The power supply is located on one side of the outside of the enclosure and is electrically connected to the magnetic suction part and the motor.
[0008] The control component is located on one side of the exterior of the enclosure and is electrically connected to the power supply.
[0009] Furthermore, a hollow crushing chamber is included between the feed inlet and the conveying chamber. A crushing paddle and a crushing motor connected to the crushing paddle are installed inside the crushing chamber and located on the outside of the box. The crushing paddle is electrically connected to the control component. A filter screen is installed between the crushing chamber and the conveying chamber. A through-hole large material discharge pipe is installed on one side of the crushing chamber of the box.
[0010] Furthermore, the conveyor belt is provided with several outwardly protruding arc-shaped partitions.
[0011] Furthermore, the partition is roughly prepared.
[0012] Furthermore, the screening ports include at least two, and the magnetic suction parts include at least two.
[0013] Furthermore, the distance between the screening port near the bottom and the bottom of the conveyor belt is greater than or equal to 1.5m.
[0014] Furthermore, the soil discharge pipe is arranged in an arc shape to one side, and the metal discharge pipe is also arranged in an arc shape to one side.
[0015] In this application, the soil to be remediated enters the conveying chamber through the feed inlet at the top of the chamber and moves downwards under gravity. When the soil reaches the screening inlet, the magnetic attraction unit inside the separation chamber generates a magnetic force under power supply, adsorbing metals in the soil. These metals enter the separation chamber through the screening inlet and are conveyed onto a conveyor belt. The conveyor belt, under the action of the magnetic attraction unit, moves the metals adsorbed on its surface towards the bottom of the separation chamber. As the distance increases, the magnetic force of the magnetic attraction unit on the metal gradually weakens until gravity exceeds the magnetic attraction force, at which point the metals fall off the conveyor belt and enter the metal discharge pipe at the bottom of the separation chamber for discharge outside the chamber. The magnetic attraction unit effectively adsorbs metal impurities from the soil, ensuring that the treated soil quality meets environmental standards.
[0016] The remediation box of this application utilizes the magnetic field generated by the magnetic attraction unit to adsorb metals in the soil, efficiently separating the metals from the soil and ensuring that the treated soil meets environmental protection requirements. The conveyor belt design allows the adsorbed metals to naturally detach and enter the metal discharge pipe after a certain distance, reducing the need for manual intervention and improving work efficiency. By adjusting the power supply status through the control component, the magnetic strength of the magnetic attraction unit can be adjusted according to actual conditions to prevent metals from being adsorbed onto the conveyor belt and difficult to detach, ensuring the continuous and efficient operation of the remediation box.

Detailed Implementation
[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below.
[0022] This utility model discloses a soil remediation box 100 for soil remediation, such as... Figure 1As shown, it includes a housing 11, with a through-feed inlet at the top and a hollow conveying chamber below the inlet. A hollow separation chamber is located on one side of the conveying chamber. Figure 2 The conveying chamber and the separation chamber shown are separated by a partition plate 111. A soil discharge pipe 112 is installed through the side of the housing 11 near the lower part of the conveying chamber, and a screening port is installed through the side of the partition plate 111 near the upper part. Figure 3As shown, a track 113 and a conveyor belt 114 are arranged inside the separation chamber. A magnetic suction part 116 corresponding to the screening port is arranged on the side of the separation chamber of the housing 11 away from the screening port. A metal discharge pipe 117 is provided through the lower part of the separation chamber of the housing 11. A motor 12 is located on one side outside the housing 11 and is connected to the track 113 through the housing 11. A power supply 13 is located on one side outside the housing 11 and is electrically connected to the magnetic suction part 116 and the motor 12. The power supply 13 can control the start of the motor 12, thereby causing the motor 12 to drive the conveyor belt on the track 113 to move. A control component 14 is located on one side outside the housing 11 and is electrically connected to the power supply 13. The remediation box 100 of this application primarily functions to remove metals from the soil through magnetic attraction. The soil to be remediated enters the conveying chamber of the box 11 through the feed inlet at the top of the box 11. Inside the conveying chamber, the soil moves downwards under gravity. Meanwhile, the magnetic attraction part 116 in the separation chamber generates magnetic force when the power supply 13 is turned on, attracting the metals in the soil. The metals then enter the separation chamber through the screening port. To prevent excessive metal from being attracted by the magnetic attraction part 116 and thus affecting the magnetic properties... The magnetic suction unit 116 has an adsorption capacity for soil. In this application, a conveyor belt 114 is installed inside the separation chamber. Under the action of the magnetic suction unit 116, metals in the soil are adsorbed onto the conveyor belt 114. The conveyor belt 114 moves on the track 113, thus moving the metals towards the bottom of the separation chamber. After moving a certain distance, the magnetic force of the magnetic suction unit 116 on the metals decreases due to the distance. When gravity exceeds the magnetic force, the metals fall off the conveyor belt 114 and enter the metal discharge pipe 117 at the bottom of the separation chamber, exiting the housing 11. Soil to be repaired enters the separation chamber through the feed inlet at the top of the housing 11 and moves downwards under gravity. When the soil reaches the screening port, the magnetic suction unit 116 inside the separation chamber generates a magnetic force under the power supply 13, adsorbing the metals in the soil. These metals enter the separation chamber through the screening port and are conveyed onto the conveyor belt 114. Under the action of the magnetic suction unit 116, the conveyor belt 114 moves the metals adsorbed on its surface towards the bottom of the separation chamber. As the distance increases, the magnetic force of the magnetic attraction part 116 on the metal gradually weakens until gravity exceeds the magnetic attraction force. At this point, the metal falls off the conveyor belt 114 and enters the metal discharge pipe 117 at the bottom of the separation chamber, exiting the housing 11. The magnetic attraction part 116 effectively adsorbs metal impurities from the soil, ensuring that the treated soil meets environmental standards. This application utilizes the magnetic field generated by the magnetic attraction part 116 to adsorb metals in the soil, efficiently separating the metals and ensuring that the treated soil meets environmental requirements. The design of the conveyor belt 114 allows the adsorbed metals to naturally fall into the metal discharge pipe 117 after a certain distance, reducing the need for manual intervention and improving work efficiency.By adjusting the working state of the power supply 13 through the control component 14, the magnetic strength of the magnetic suction part 116 can be adjusted according to the actual situation, so as to prevent the metal from being attracted to the conveyor belt 114 and difficult to fall off, thus ensuring the continuous and efficient operation of the repair box 100.
[0023] In one implementation, a hollow crushing chamber is included between the feed inlet and the conveying chamber. A crushing paddle 15 and a crushing motor 16 connected to the crushing paddle 15 and located on the outside of the housing 11 are installed within the crushing chamber. The crushing paddle 15 is electrically connected to a control component 14. When the crushing paddle 15 is in use, the control component 14 controls the power supply 13 to connect the crushing motor 16, which then starts and drives the crushing paddle 15 to crush the soil. A filter screen is installed between the crushing chamber and the conveying chamber. A through-hole large material discharge pipe 17 is installed on one side of the crushing chamber of the housing 11. Larger soil clods can hinder the effective adsorption of metals in the soil by the magnetic adsorption unit 116. By crushing large soil clods into smaller particles using the crushing paddle 15 within the crushing chamber, it is ensured that metals are more easily exposed and effectively adsorbed by the magnetic adsorption unit 116. Contaminated soil from different sources may contain soil clods of various sizes. The crushing chamber allows the remediation tank 100 to handle a wider range of soil types, enhancing the versatility and adaptability of the remediation tank 100. The control component 14 can adjust the operating parameters of the crushing paddle 15, such as its rotation speed, as needed to adapt to soil lumps of different hardness or size, expanding the application scenarios of the remediation box 100. Crushed soil particles more easily pass through the filter screen into the conveying chamber, reducing filter screen clogging caused by large soil lumps and ensuring smooth metal flow. The filter screen helps intercept incompletely crushed large soil lumps, allowing them to be discharged through the large material discharge pipe 17, reducing the frequency of manual cleaning of the filter screen and other internal components, thus lowering maintenance difficulty and cost. By adding a crushing chamber, crushing paddle 15, and matching filter screen and large material discharge pipe 17 between the inlet and the conveying chamber, not only is the metal adsorption efficiency improved, but the adaptability and stability of the remediation box 100 are also enhanced, the maintenance process is simplified, and resource reuse and environmental protection are promoted.
[0024] In one implementation, the conveyor belt 114 is provided with several outwardly protruding arc-shaped partitions 1141. The partitions 1141 are used to separate and move the metal downwards, preventing excessive magnetic attraction from the magnetic attraction part 116 and preventing the metal from being continuously attracted to the conveyor belt 114. The attraction force of the magnetic attraction part 116 may cause the metal to remain on the conveyor belt 114 for an extended period, affecting subsequent metal attraction. The arc-shaped partitions 1141 effectively separate the metal and gradually carry it away from the lower part of the separation chamber until it leaves the effective range of the magnetic attraction part 116 as the conveyor belt 114 moves, ensuring that the metal can fall off naturally and improving overall conveying efficiency. The partitions 1141 help disperse the metal attracted to the conveyor belt 114, avoiding the problem of poor adsorption in some areas due to excessive metal concentration, allowing the metal to be more evenly distributed on the conveyor belt 114, which is beneficial for improving the separation effect. Physical separation prevents excessive metal accumulation in the same area, reducing the risk of blockages caused by metal buildup and ensuring smooth operation of conveyor belt 114. Effective management of metal distribution on conveyor belt 114 reduces the need for manual cleaning or handling of metal buildup, lowering maintenance costs and time. The arc-shaped separator 1141 is designed to adjust its spacing and height according to actual needs, accommodating different types and sizes of metal particles, enhancing the flexibility and adaptability of the repair box 100.
[0025] In one implementation, the separator 1141 is roughened. The rough surface increases friction, which helps to better grip and secure the metal attracted to the conveyor belt 114 by the magnetic attachment 116. This is beneficial for irregularly shaped or heavy metal fragments, ensuring they do not easily slip or re-enter the soil during transport. A smooth surface can cause metal to slide on the conveyor belt 114, especially when the conveyor belt 114 is inclined or traveling at high speeds. The rough surface effectively increases the coefficient of friction, reduces slippage, and ensures the metal moves stably with the conveyor belt 114.
[0026] In one implementation, the system includes at least two screening ports and at least two magnetic adsorption units 116. Multiple screening ports allow more soil to pass through and enter the separation chamber for metal adsorption treatment, thereby increasing the processing capacity per unit time. This enables the entire system to process large quantities of contaminated soil more quickly. Multiple magnetic adsorption units 116 can cover a larger area, ensuring that soil entering the separation chamber from different locations receives sufficient metal adsorption treatment, improving overall adsorption efficiency. The design of multiple screening ports and magnetic adsorption units 116 helps achieve a more uniform adsorption distribution. This avoids the problem of metal residue in some areas due to insufficient adsorption, ensuring that the soil in each section is thoroughly cleaned. Multiple magnetic adsorption units 116 can operate at different heights or positions, forming a multi-layered adsorption system, further improving the capture rate of metal particles of different types and sizes.
[0027] In one implementation, the distance between the screening port near the bottom and the bottom of the conveyor belt 114 is greater than or equal to 1.5m. If the screening port is too close to the bottom of the conveyor belt 114, the distance between the magnetic attraction part 116 and the metal on the conveyor belt 114 will be short, which may result in excessively strong magnetic force, making it difficult for the metal to fall off once attracted. By increasing the distance between the screening port and the bottom to greater than or equal to 1.5m, it can be ensured that the metal gradually moves away from the strong attraction range of the magnetic attraction part 116 during movement, thus making it easier for it to fall off naturally at the bottom of the separation chamber. As the metal moves away from the magnetic attraction part 116 with the conveyor belt 114, the magnetic force weakens due to the increased distance, and the metal will fall off the conveyor belt 114 under the action of gravity. By reasonably setting the distance between the screening port and the bottom, the metal can automatically fall off at a predetermined position and enter the metal discharge pipe 117 before reaching the end of the conveyor belt 114, ensuring the efficiency and accuracy of metal collection. A larger distance allows the metal to undergo a gradual process of leaving the magnetic field, which helps to more finely separate different types of metals. For example, lighter or smaller metals may detach earlier, while heavier or larger metals require a greater distance to completely escape the magnetic field, thus improving the overall separation accuracy.
[0028] In one implementation, the soil discharge pipe 112 is curved to one side, and the metal discharge pipe 117 is also curved to one side. The curved design provides a smoother metal flow path, reducing resistance and friction when the metal turns or bends. This helps prevent blockages or accumulation of soil or metal during discharge, ensuring smooth discharge from the repair box 100. Compared to right-angle turns, the curved design reduces the impact of metal on the inner wall of the pipe, lowers wear inside the pipe, and extends the service life of the discharge pipe.
