Description
Technical Field
[0001] This utility model relates to the technical field of soil pollution remediation equipment, specifically a soil pollution remediation device. Background Technology
[0002] Soil pollution refers to the phenomenon where toxic and harmful substances enter the soil, exceeding the soil's self-purification capacity, leading to the deterioration of the soil's physical, chemical, and biological properties, and thus threatening ecological environment security and human health. Pollution sources include industrial wastewater and waste residue discharge, overuse of agricultural fertilizers and pesticides, and landfill leakage of domestic waste. It is characterized by its hidden nature, long-term nature, and difficulty in remediation, and requires the gradual restoration of soil function through soil remediation technology.
[0003] The process of soil pollution remediation first requires a detailed investigation and testing of the polluted soil. By collecting samples and analyzing the types of pollutants, the polluted soil is excavated during ex-situ remediation and purified using methods such as thermal desorption and leaching. Soil indicators are monitored during the remediation period to assess the remediation effect and ensure that the pollutant concentration is reduced to a safe level, ultimately restoring the soil's ecological function.
[0004] When treating soil, specific agents need to be sprayed. However, existing agents have a limited spraying range, resulting in uneven contact between the soil and the agent when entering the equipment, which leads to a decrease in the treatment effect. Therefore, a soil pollution treatment device is proposed to address the above problems. Utility Model Content

A sliding plate is connected to the side wall of the container; a pair of first motors drive the crushing shaft to rotate and compress the soil, which can quickly break up lumpy soil into fine particles, increase the specific surface area of the soil, and make the agent sprayed by the spray head more fully in contact with the soil. Multiple sets of spray heads are evenly distributed on the inner side wall of the container. With the stirring shaft turning the soil, the agent can be sprayed to various parts of the soil from multiple directions and different angles, reducing blind spots in single-location spraying. During the rotation of the stirring shaft, the soil particles are continuously moved, so that the agent can fully contact and react with the soil, improving the effect of soil treatment. The bottom of the container is set at an inclination, which, combined with the turning action of the stirring shaft, can guide the soil to move towards the discharge port.
[0007] Preferably, a crossbar is rotatably connected to the side wall of the container; a smoothing bar is fixed to the bottom end of the crossbar; the smoothing bars are evenly distributed at the bottom end of the crossbar; by rotating the crossbar, the evenly distributed smoothing bars can be driven to spread the soil flowing out of the outlet in real time, reduce soil accumulation, make the treated soil more uniform on the ground surface, and reduce the need for secondary leveling of the soil after treatment.
[0008] Preferably, a baffle plate is slidably connected to the middle of the container; the baffle plate is positioned above the spray head; multiple sets of perforations are opened at the top of the baffle plate; the perforations are evenly distributed at the top of the baffle plate; a handle is fixedly connected to the side wall of the baffle plate; the crushed soil is screened by the multiple sets of perforations, smaller particles fall to the bottom through the sieve holes to mix with the agent, and larger soil clumps remain above the baffle plate, reducing the amount of insufficiently crushed soil falling to the bottom of the container and increasing the reaction effect between the treated soil and the agent.
[0009] Preferably, a pair of blocking blocks are fixed to the side wall of the container; the blocking blocks are located near the discharge port; the pair of blocking blocks prevent soil from accumulating in the corners of the container, so that the soil is always in the center of the mixing area of the mixing shaft when the mixing shaft is turned, reducing the accumulation of soil due to moving to a position that the mixing shaft cannot turn, and increasing the spraying effect of the spray head.
[0010] Preferably, a flat plate is fixed to the bottom of the container; a pair of support rods are fixed to the bottom of the flat plate; a container is fixed to the top of the support rods; multiple sets of rotating wheels are fixed to the bottom of the flat plate; and a pusher is fixed to the side wall of the flat plate. By pulling the pusher, the rotating wheels are rotated, causing the soil to flow out of the outlet and move simultaneously, cooperating with the leveling rod to flatten the soil and reduce soil accumulation caused by static discharge when the soil is discharged from the outlet.
[0011] Preferably, a dust-proof cloth is fixed to the side wall of the container; the dust-proof cloth is positioned above the barrier plate; by blocking the dust above the barrier plate with the dust-proof cloth, the dust dispersion when the crushing shaft crushes the soil can be reduced, and the crushed soil can also be prevented from flying out from above the barrier plate.
[0012] The advantages of this utility model are:

The bottom of the container is set at an inclination, which, combined with the turning action of the stirring shaft, can guide the soil to move towards the discharge port.
[0014] 2. The soil pollution remediation equipment described in this utility model uses multiple sets of perforations to screen the crushed soil by particle size. Smaller particles fall through the perforations to the bottom for mixing with the reagent, while larger soil particles are retained above the baffle plate, reducing the amount of insufficiently crushed soil falling to the bottom of the container and increasing the reaction effect between the treated soil and the reagent.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a soil pollution remediation device includes a container 1; a feed inlet 11 is provided at the top of the container 1; a pair of first motors 12 are fixedly connected to the side wall of the container 1; a crushing shaft 13 is fixedly connected to the output end of the first motors 12; a water pump 14 is fixedly connected to the side wall of the container 1; the water pump 14 is located to the side of the first motors 12; a reagent tank 15 is fixedly connected below the water pump 14; multiple sets of spray heads 16 are fixedly connected to the inner side wall of the container 1; the spray heads 16 are evenly distributed on the inner side wall of the container 1; the bottom of the container 1 is inclined; the bottom of the container 1 is fixedly... A second motor 110 is connected; a stirring shaft 17 is fixedly connected to the output end of the second motor 110; a discharge port 18 is opened on the side wall of the container 1; a sliding plate 19 is slidably connected to the side wall of the discharge port 18; during operation, the soil to be treated is added into the container 1 from the middle of the inlet 11. After the soil enters the container 1, a pair of first motors 12 are started to drive the crushing shaft 13 to rotate, squeezing and contacting the soil falling from the inlet 11, thus crushing the soil. The soil crushed by the crushing shaft 13 falls to the bottom of the container 1. The second motor 110 is then started to drive the stirring shaft 17 to rotate. 17 contacts the soil at the bottom of container 1, turning over the soil. While turning over the soil at the bottom of container 1, the water pump 14 is activated to spray the agent inside the agent tank 15 from multiple spray heads 16. The agent is evenly sprayed into contact with the turned soil at the bottom of container 1. After the soil treatment inside container 1 is completed, a pulling force is applied to the slide plate 19, causing the slide plate 19 to move above the discharge port 18, opening the discharge port 18. The soil can then flow out from the discharge port 18, completing the treatment. A pair of first motors 12 drive the crushing shaft 13 to rotate and compress the soil, quickly breaking up lumpy soil. The soil is broken into fine particles, increasing its specific surface area and allowing the agent sprayed by the spray head 16 to make more thorough contact with the soil. Multiple spray heads 16 are evenly distributed on the inner side wall of the container 1. With the help of the stirring shaft 17 to turn the soil, the agent can be sprayed from multiple directions and angles to various parts of the soil, reducing blind spots in single-location spraying. As the stirring shaft 17 rotates and turns the soil, it continuously drives the soil particles to move, ensuring that the agent and soil fully contact and react, thus improving the effect of soil treatment. The bottom of the container 1 is tilted, which, combined with the turning action of the stirring shaft 17, can guide the soil to move towards the discharge port 18.
[0025] like Figures 1 to 5 As shown, a crossbar 2 is rotatably connected to the side wall of the container 1; a smoothing bar 21 is fixed to the bottom end of the crossbar 2; the smoothing bars 21 are evenly distributed at the bottom end of the crossbar 2; during operation, after the soil inside the container 1 flows out from the discharge port 18, a rotational force is applied to the crossbar 2, and the smoothing bars 21 can flatten the flowing soil; by rotating the crossbar 2 to drive the evenly distributed smoothing bars 21, the soil flowing out from the discharge port 18 can be flattened in real time, reducing soil accumulation and making the treated soil more uniform on the ground surface, reducing the need for secondary flattening of the soil after treatment.
[0026] like Figure 2 and Figure 5 As shown, a baffle plate 3 is slidably connected to the middle of the container 1; the baffle plate 3 is positioned above the spray head 16; multiple sets of perforations 31 are opened at the top of the baffle plate 3; the perforations 31 are evenly distributed at the top of the baffle plate 3; a handle 32 is fixedly attached to the side wall of the baffle plate 3; during operation, after the crushing shaft 13 crushes the soil in the middle of the container 1, smaller soil particles can fall from the middle of the perforations 31, while larger soil particles can remain above the baffle plate 3. Applying a pulling force to the handle 32 can pull the baffle plate 3 out as a whole from the side wall of the container 1, further crushing the large pieces of soil remaining on the surface of the baffle plate 3; the crushed soil is screened by the multiple sets of perforations 31, with smaller particles falling to the bottom through the sieve holes for mixing with the pesticide, while large pieces of soil remain above the baffle plate 3, reducing the amount of insufficiently crushed soil falling to the bottom of the container 1 and increasing the reaction effect between the treated soil and the pesticide.
[0027] like Figure 3 As shown, a pair of blocking blocks 4 are fixed to the side wall of the container 1; the blocking blocks 4 are located near the discharge port 18; during operation, the soil at the bottom of the container 1 will be distributed around the corners of the container 1 when it is being crushed. When the stirring shaft 17 turns the soil, the blocking blocks 4 can prevent the soil from staying around the container 1 and keep the soil on the side of the stirring shaft 17; by preventing the soil from accumulating around the corners of the container 1 through a pair of blocking blocks 4, the soil is always in the center of the stirring area of the stirring shaft 17 when it is turning, reducing the accumulation of soil due to moving to a position that the stirring shaft 17 cannot turn, and increasing the spraying effect of the spray head 16.
[0028] like Figure 5 As shown, a flat plate 5 is fixed to the bottom of the container 1; a pair of support rods 51 are fixed to the bottom of the flat plate 5; the container 1 is fixed to the top of the support rods 51; multiple sets of rotating wheels 52 are fixed to the bottom of the flat plate 5; and a pusher 53 is fixed to the side wall of the flat plate 5. During operation, when the soil in the middle of the discharge port 18 flows out, it can apply a pulling force to the pusher 53, causing the rotating wheels 52 to rotate and move the container 1 as a whole. This, together with the leveling rod 21, allows the soil flowing out of the middle of the discharge port 18 to move and fall while being leveled by the leveling rod 21. By pulling the pusher 53 to drive the rotating wheels 52 to rotate, the soil flows out of the discharge port 18 and moves at the same time, cooperating with the leveling rod 21 to level the soil and reduce soil accumulation caused by static discharge when the discharge port 18 is discharged.
[0029] like Figure 5As shown, a dust-proof cloth 6 is fixed to the side wall of the container 1; the dust-proof cloth 6 is positioned above the baffle plate 3; during operation, when the crushing shaft 13 crushes the soil, the dust-proof cloth 6 can prevent the dust from flowing out from the opening above the baffle plate 3 during crushing, and can also further prevent the soil from leaking out from above the baffle plate 3; by blocking the dust above the baffle plate 3 with the dust-proof cloth 6, the dust dispersion when the crushing shaft 13 crushes the soil can be reduced, and the crushed soil can also be prevented from flying out from above the baffle plate 3.
[0030] Working principle: The soil to be treated is added into the container 1 through the middle of the feed inlet 11. After the soil enters the container 1, a pair of first motors 12 are started to drive the crushing shaft 13 to rotate, squeezing and crushing the soil falling from the feed inlet 11. The crushed soil falls to the bottom of the container 1, and the second motor 110 is started to drive the stirring shaft 17 to rotate. The stirring shaft 17 contacts the soil at the bottom of the container 1, turning the soil at the bottom of the container 1. 7. While turning over the soil at the bottom of container 1, start water pump 14 to spray the agent inside the agent tank 15 from multiple spray heads 16. The agent is evenly sprayed into contact with the turned soil at the bottom of container 1. After the soil treatment inside container 1 is completed, apply pulling force to the slide plate 19 to move the slide plate 19 above the discharge port 18 to open the discharge port 18. The soil can then flow out from the discharge port 18 to complete the treatment. After the soil inside container 1 flows out from the discharge port 18, apply rotational force to the crossbar 2. The leveling bar 21 can then... After the soil is leveled, the crushing shaft 13 crushes the soil in the middle of container 1. Smaller soil particles can fall through the center of the drain hole 31, while larger soil particles can remain above the baffle plate 3. Applying a pulling force to the handle 32 can pull the baffle plate 3 out along the side wall of container 1, further crushing the large pieces of soil remaining on the surface of the baffle plate 3. The soil at the bottom of container 1 will be distributed around the corners of container 1 during the crushing process. When the stirring shaft 17 turns the soil over, the blocking block 4 can prevent the soil from remaining around the perimeter of container 1. The soil is blocked to the side of the mixing shaft 17. When the soil in the middle of the discharge port 18 flows out, it can apply a pulling force to the pusher 53, drive the rotating wheel 52 to rotate, and move the container 1 as a whole. With the help of the smoothing rod 21, the soil flowing out of the middle of the discharge port 18 moves and falls while being flattened by the smoothing rod 21. When the crushing shaft 13 crushes the soil, the dust cover 6 can prevent the dust during crushing from flowing out from the opening above the baffle plate 3, and can also further prevent the soil from leaking out from above the baffle plate 3.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
