[0002] Natural processes such as volcanic eruptions and rock weathering, as well as human activities such as industrial emissions, agricultural activities, mineral mining, and urban garbage stacking, make the soil contain heavy metal substances. Soil heavy metals affect the activity of soil microorganisms, reduce soil fertility, affect crop growth, and may also be transmitted through the food chain and ultimately enter the human body, leading to various health problems. In the ion filtration operation of soil heavy metal remediation, a filter screen is usually used to filter and adsorb the flowing soil, and a metal adsorption material is used to adsorb and filter the heavy metals in the soil, so as to achieve the effect of purifying the soil. However, the filtering effect of the filter screen is limited and the residues cannot be quickly cleaned, and the filtering effect is limited.

[0003] In view of the above problems, an ion filtration device for soil heavy metal remediation is now developed. Content of the Utility Model

[0005] The technical solution of the utility model is: an ion filtration device for soil heavy metal remediation, which includes a mounting base. A filter pipe is connected to the mounting base. Two limiting components are clamped inside the filter pipe. A flow guide plate is connected between the two limiting components with a nut. The flow guide plate is of a spiral structure. A feed pipe is placed on the filter pipe. First connection components are connected to both the left and right parts of the filter pipe. The first connection components include first connectors and locking parts. The first connectors are installed on both the left and right parts of the filter pipe, and the locking parts are threadedly connected to the connectors. Second connection components are connected to both the left and right parts of the feed pipe. The second connection components each include a second connector and a rotating block. The second connectors are connected to both the left and right parts of the feed pipe, and the rotating blocks are rotatably connected to the connectors. The locking parts and the adjacent rotating blocks are all rotatably connected. A filtering mechanism is arranged inside the feed pipe.

[0006] Optionally, the filtering mechanism includes a filter plate. The filter plate is clamped inside the feed pipe. Three dampers are connected to the filter plate. A buffer block is connected between the dampers. Buffer springs are connected inside the dampers.

[0007] Optionally, a pumping mechanism is further included. The pumping mechanism includes a mounting member, the mounting member is mounted on the mounting seat, a water pump is mounted on the mounting member, a return pipe is connected to the water pump, and the return pipe is connected to the mounting seat and the feed pipe.

[0009] Optionally, two assisting members are provided on the filter plate.

[0010] Optionally, the upper side of the buffer block is of an arc surface structure.

[0011] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows: When the fluid soil contacts the limiting component, the limiting component performs a second filtration on the fluid soil, the heavy metal adsorption material on the diversion plate adsorbs and filters the heavy metals in the fluid soil, and the spiral structure of the diversion plate can extend the residence time of the fluid soil, making the filtration more sufficient.

Detailed Embodiments

[0018] The following describes the embodiments of the present utility model with reference to the drawings.

[0019] Embodiment 1

[0020] An ion filtration device for soil heavy metal remediation, as Figures 1 - 3 shown, includes a mounting base 1, a filter tube 2 is connected to the mounting base 1, two limiting components 21 are clamped inside the filter tube 2, a flow guide plate 22 is connected between the two limiting components 21 with a nut, the flow guide plate 22 is of a spiral structure, a feed pipe 5 is placed on the filter tube 2, both the left and right parts of the filter tube 2 are connected with a first connection component 3, the first connection component 3 includes a first connecting piece and a locking piece, both the left and right parts of the filter tube 2 are provided with the first connecting piece, and the locking piece is threadedly connected to the connecting piece, both the left and right parts of the feed pipe 5 are connected with a second connection component 4, the second connection component 4 includes a second connecting piece and a rotating block, both the left and right parts of the feed pipe 5 are connected with the second connecting piece, and the rotating block is rotatably connected to the connecting piece, the locking piece and the adjacent rotating block are rotatably connected, a rubber pad is connected between the filter tube 2 and the feed pipe 5, and a filtering mechanism 6 is arranged inside the feed pipe 5.

[0021] As Figure 2 and Figure 4 shown, the filtering mechanism 6 includes a filter plate 61, the filter plate 61 is clamped inside the feed pipe 5, two assisting pieces are arranged on the filter plate 61, three dampers 62 are connected to the filter plate 61, a buffer block 64 is connected between the dampers 62, the upper side of the buffer block 64 is of an arc surface structure, and buffer springs 63 are connected inside the dampers 62.

[0022] Natural processes such as volcanic eruptions and rock weathering and human activities such as industrial emissions, agricultural activities, mineral mining, and urban garbage dumping cause the soil to contain heavy metal substances. Soil heavy metals affect the activity of soil microorganisms, reduce soil fertility, and affect crop growth. They may also be transmitted through the food chain and eventually enter the human body, causing various health problems. Unfiltered liquid soil is injected into the feed pipe 5. The arc surface structure on the upper part of the buffer block 64 can disperse the liquid soil to the surroundings. The damper 62 and the buffer spring 63 can buffer the buffer block 64 when it is impacted by the liquid soil. The filter plate 61 filters the liquid soil for the first time. The liquid soil moves downward. When it contacts the limit assembly 21, the limit assembly 21 filters the liquid soil for the second time. The heavy metal adsorption material on the guide plate 22 adsorbs and filters the heavy metals in the liquid soil. The spiral structure of the guide plate 22 can prolong the retention time of the liquid soil, making the filtration more complete. The filtered liquid soil flows into the inside of the mounting seat 1 and is detected. When it is necessary to clean the residue on the filter plate 61, the filter plate 61 can be lifted up by the power assist member, so that the filter plate 61 can be taken out from the feed pipe 5. When it is necessary to replace the guide plate 22 or clean the residue inside the filter tube 2, the locking member is rotated to disengage the rotating block from the locking state of the adjacent locking member, and then the rotating member is rotated to separate the feed pipe 5 from the filter tube 2. Then the power assist member is used to lift the limit assembly 21 and the guide plate 22 upward, and then the nuts on the upper and lower sides of the guide plate 22 are rotated to remove the guide plate 22 and clear the residue inside the filter tube 2. This method makes it more convenient to clean the residue on the filter plate 61 or the guide plate 22.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a pumping mechanism 7, which includes a mounting member 72. The mounting member 72 is installed on the mounting seat 1, and a water pump 71 is installed on the mounting member 72. The water pump 71 is connected to a return pipe 73, and the return pipe 73 is connected to the mounting seat 1 and the feed pipe 5.

[0025] If the filtered liquid soil is still unqualified after testing, the water pump 71 is turned on to extract the liquid soil inside the mounting base 1 and filter it again through the reflux pipe 73. This method can avoid insufficient filtration of soil heavy metals, thereby making the soil heavy metal filtration more thorough.

[0026] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
