Description

Technical Field

[0001] This utility model relates to the field of removal device technology, and more specifically, to an environmentally friendly removal device for heavy metal pollutants in soil. Background Technology

[0002] The core design of soil heavy metal environmental remediation devices revolves around "separating and fixing heavy metals to avoid secondary pollution." Based on technical principles, they can be divided into four main categories: physical separation, chemical stabilization, bioremediation, and electro-remediation. Magnetic separators are commonly used devices belonging to the physical separation category. Their core advantage is that physical separation involves no chemical additives and no secondary pollution. They can achieve the enrichment and recovery of heavy metal minerals. After pretreatment with crushing and screening, they have high separation efficiency for coarse heavy metal particles and are suitable for contaminated soils with low clay content and where heavy metals exist in the form of crystalline minerals. Magnetic separators utilize the magnetic difference between heavy metal minerals and soil particles to achieve separation: they have a built-in high-strength magnetic separator. A stable magnetic field is generated by a permanent magnet or electromagnet. After pre-treated uniform soil particles enter the magnetic field area, magnetic heavy metal minerals are adsorbed onto the surface of the drum by the magnetic field. As the drum rotates and leaves the magnetic field range, they fall into a special collection bin under the action of gravity and scrapers. Non-magnetic soil particles are not affected by the magnetic field and are discharged along the tangential direction of the drum. No chemical agents are added in the whole process. Heavy metal enrichment is achieved through physical adsorption, which avoids secondary pollution and can recover heavy metal resources. It is suitable for the efficient purification of soil with moderate to light magnetic heavy metal pollution. Since the contact between the soil and the magnetic separator directly affects the magnetic separation effect, it is necessary to carry out magnetic separation restriction operation.

[0003] In related technologies, during the use of magnetic separators, the soil that needs to be magnetically separated to remove heavy metals is generally directly transported to the top of the magnetic separator drum. As the soil flows downward, it comes into contact with the magnetic separator drum, prompting the drum to perform heavy metal separation on the soil for use.

[0004] However, during the current use of magnetic separators, when the soil flows directly downwards and comes into contact with the magnetic separator drum, the contact thickness between the soil and the magnetic separator drum is easily uncontrollable. This makes it difficult for the magnetic separator drum to uniformly separate heavy metals from the soil, thus affecting the magnetic separation effect of the magnetic separator in removing heavy metals.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4 This utility model provides a technical solution: an environmentally friendly soil heavy metal pollutant removal device, including a base frame 1 and a removal limiting mechanism. A magnetic separator 2 is installed on the top of the inner side of the base frame 1, and a baffle 3 is installed on the front side of the inner side of the base frame 1. This baffle 3 can form a soil thickness limiting medium on the front side of the magnetic separator 2, so that the user can control the thickness of the soil flowing through the magnetic separator 2 according to the actual heavy metal removal needs. This avoids the situation where the magnetic separator 2 is unable to uniformly magnetically separate heavy metals in the soil, thus improving the magnetic separation heavy metal removal effect of the magnetic separator 2.

[0021] Reference Figures 1-4 In a preferred embodiment, the removal limiting mechanism includes a limiting plate 4, which is movably connected to the left side of the front of the magnetic separator 2. A limiting strip 5 is movably connected to the right side of the limiting plate 4. An active cavity 6 is opened on the right side of the limiting plate 4. An active plate 7 located inside the active cavity 6 is fixedly connected to the left side of the limiting strip 5. The limiting connection mechanism is movably connected to the front sides of the top two sides of the base frame 1. According to the actual heavy metal magnetic separation thickness limitation requirements of the external soil, the active plate 7 is moved back and forth by the limiting plate 4 and the limiting strip 5. According to the width of the magnetic separator 2, the active plate 7 is moved inside the active cavity 6 by holding the limiting strip 5, so that the limiting width range between the limiting plate 4 and the limiting strip 5 can be adjusted, so that the limiting plate 4 cooperates with the limiting strip 5 and the active plate 7 to limit the thickness of the soil magnetically separated by the magnetic separator 2.

[0022] The limiting connection mechanism includes a connecting seat 8, a connecting port 9, and a connecting rod 10. The connecting seat 8 is movably connected to the front sides of both sides of the top of the base frame 1. The connecting port 9 is opened on the front side of the connecting seat 8. The connecting rod 10 is movably connected inside the connecting port 9. The front side of the connecting rod 10 is fixedly connected to the rear side of the limiting plate 4 and the limiting strip 5, respectively. This allows for the installation and connection of the limiting plate 4, the limiting strip 5, and the base frame 1. This enables the user to move the limiting plate 4 and the limiting strip 5 back and forth according to actual usage needs, and adjust the limiting position of the limiting plate 4 and the limiting strip 5. This avoids situations where the limiting plate 4 and the limiting strip 5 are difficult to connect to the base frame 1 or difficult to adjust during use, thus improving the ease of installation and adjustment of the limiting strip 5 and the limiting plate 4.

[0023] Reference Figures 2-4In a preferred embodiment, fixing holes 11 are provided on both sides of the top of the connecting seat 8. Fixing bolts 12 that are threadedly connected to the base frame 1 are movably connected inside the fixing holes 11. The threaded connection between the connecting seat 8 and the base frame 1 can be tightened, avoiding the situation where the connecting seat 8 is difficult to install and fix during operation. Therefore, the installation and fixing of the connecting seat 8 is improved. A reinforcing seat 13 is fixedly connected to the front side of the top of the connecting rod 10. The front side of the reinforcing seat 13 is fixedly connected to the rear side of the limiting plate 4 and the limiting strip 5 respectively. The connection between the connecting rod 10 and the limiting plate 4 and the limiting strip 5 can be reinforced, avoiding the situation where the connection force between the connecting rod 10 and the limiting plate 4 and the limiting strip 5 is insufficient. Therefore, the connection effect between the connecting rod 10 and the limiting plate 4 and the limiting strip 5 is improved.

[0024] Reference Figures 2-4 In a preferred embodiment, a positioning cylinder 14 is fixedly connected to the front side of the top of the connecting seat 8. A positioning post 15 is movably connected inside the positioning cylinder 14. The bottom of the positioning post 15 is inserted into the top of the connecting rod 10, which allows for the insertion and positioning of the connecting rod 10 and the connecting seat 8. This avoids the situation where the connecting rod 10 is difficult to position during use, thus improving the positioning convenience of the connecting rod 10. The top of the connecting rod 10 is provided with a positioning hole 16 that communicates with the positioning cylinder 14. The bottom of the positioning post 15 is located inside the positioning hole 16, which can provide multiple insertion and positioning spaces for the positioning post 15. This avoids the situation where the positioning post 15 is difficult to meet the positioning requirements of the connecting rod 10 during use, thus improving the insertion and positioning flexibility of the positioning post 15.

[0025] Reference Figures 2-4 In a preferred embodiment, a limiting cavity 17 is provided on the inner wall of the positioning cylinder 14, and a limiting block 18 is movably connected inside the limiting cavity 17. The front side of the limiting block 18 is fixedly connected to the rear side of the positioning post 15, which can limit the operation between the positioning post 15 and the positioning cylinder 14, and prevent the positioning post 15 from easily dislodging from the positioning hole 16 during use. Therefore, the insertion and positioning stability of the positioning post 15 is improved. A lifting port 19 is provided on the rear side of the top of the inner wall of the limiting cavity 17, and a position head 20 located on the top of the limiting block 18 is fixedly connected to the surface of the positioning post 15. This can provide space for the limiting block 18 to move out of the limiting cavity 17 and provide the user with a reference medium to clearly define the position of the limiting block 18. Therefore, the flexibility of using the positioning post 15 is improved.

[0026] Specifically, the working process or working principle of this soil heavy metal pollutant environmental protection removal device is as follows: In use, the connecting rod 10 is aligned with the connection port 9 by the limiting plate 4 and the limiting strip 5. At this time, the movable plate 7 moves inside the movable cavity 6 with the limiting strip 5 to perform the moving connection work between the limiting plate 4 and the limiting strip 5, and to expand the width between the limiting plate 4 and the limiting strip 5. Then, the connecting rod 10 is moved to the rear and enters the connection port 9. The connecting rod 10, in conjunction with the connection port 9 and the connecting seat 8, can perform the initial connection operation between the limiting plate 4, the limiting strip 5 and the base frame 1.

[0027] At this time, the fixing hole 11, together with the fixing bolt 12, performs threaded fastening and stabilization work between the connecting seat 8 and the base frame 1. At the same time, the reinforcing seat 13 performs connection and reinforcement work between the limiting plate 4, the limiting strip 5 and the connecting rod 10. Subsequently, according to the magnetic separation thickness requirements of the magnetic separator 2, the limiting plate 4 is held and the limiting strip 5 is moved back and forth to adjust the spacing between the limiting plate 4, the limiting strip 5 and the magnetic separator 2.

[0028] At this time, the connecting rod 10 moves inside the connecting port 9 to perform translational adjustment and connection guidance work between the limiting plate 4, the limiting strip 5, and the base frame 1. After the limiting plate 4 and the limiting strip 5 are adjusted, the hand-held positioning column 15 drives the limiting block 18 to rotate and align with the lifting port 19, so that the limiting block 18 moves downward with the positioning column 15 into the limiting cavity 17. At this time, the positioning column 15 moves downward into the positioning hole 16 and passes through the positioning cylinder 14 to perform insertion and positioning work between the connecting rod 10 and the connecting seat 8. This allows the adjusted limiting plate 4 and the limiting strip 5 to be positioned. Then, the hand-held positioning column 15 drives the limiting block 18 to rotate and completely enter the limiting cavity 17, thus keeping the positioning column 15 in position. At this time, the positioning head 20 moves with the positioning column 15 so that the user can clearly see the position of the limiting block 18. This allows the limiting plate 4 and the limiting strip 5 to be positioned and cooperate with the movable plate 7 to limit the thickness of heavy metals in the soil after the magnetic separator 2 is magnetically separated.

[0029] It should be noted that the base frame 1, magnetic separator 2 and baffle 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
