Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, and more specifically to a soil and water pollution remediation device. Background Art

[0002] With the acceleration of the industrialization process and the frequency of agricultural activities, the problem of soil and water pollution has become increasingly severe, posing a serious threat to the ecological environment and human health. During the remediation process of polluted soil and groundwater, the physical state of the soil directly affects the remediation effect and efficiency. Especially for polluted areas containing a large amount of caked soil, how to efficiently break these caked soils so that the pollutants in them can be more easily extracted and treated has become a technical problem to be solved urgently.

[0003] In existing soil and water pollution remediation devices, the roller milling technology is widely used for the preliminary crushing and mixing of soil. However, traditional roller milling equipment often has the problem of insufficient roller milling force, resulting in the inability to fully break caked soil, thereby affecting the effect of subsequent remediation steps. Specifically, too small roller milling force will not only reduce the crushing efficiency of the soil, but also may cause the soil to not be in full contact with the soil remediation agent, thereby affecting the soil remediation effect. Summary of the Utility Model

[0004] The utility model provides a soil and water pollution remediation device, and its beneficial effect is that it can adjust the tension of the flexible filter screen according to the caking degree of the soil, thereby changing the roller milling force, fully grinding the caked soil, and avoiding the situation that the caked soil cannot be fully broken due to too small roller milling force.

[0005] A soil and water pollution remediation device includes a box body. Inside the box body, there is a flexible filter screen with adjustable tension. At the front and rear of the upper end of the box body, two notches are symmetrically opened. Between the two notches, there is a cross beam connected in a sliding manner. Two column rods are inserted on the cross beam. On the two column rods, there is a roller frame fixedly connected. On the roller frame, there is a pressure roller rotatably connected. On both of the two column rods, there is a compression spring sleeved. The two ends of the compression spring are respectively fixedly connected to the cross beam and the roller frame.

[0006] On the box body, two through slots are symmetrically opened on the left and right. The two ends of the flexible filter screen respectively pass through the two through slots. At the outer ends of the two ends of the flexible filter screen, there is a frame fixedly connected. At both ends of the box body, there is an adjusting member for adjusting the distance between the two frames.

[0007] The adjusting member includes guide rods symmetrically fixedly connected to both ends of the box body. The two frames are respectively slidably connected to the two guide rods.

[0008] The adjusting member further includes screws symmetrically rotatably connected to both ends of the box body. The two frames are respectively threadedly connected to the two screws. Description of the Drawings

Specific implementation method

[0019] Refer to Figures 1 to 6 , which shows a schematic diagram of an embodiment for changing the roller rolling force according to the present utility model;

[0020] A soil and water pollution remediation device includes a box body 101, and a flexible filter screen 201 with adjustable tension is connected in cooperation inside the box body 101. Two slot openings 103 are symmetrically opened at the front and rear of the upper end of the box body 101. A cross beam 301 is slidably connected between the two slot openings 103. Two column rods 302 are inserted on the cross beam 301. A roller frame 304 is fixedly connected to the two column rods 302 by screws. A pressure roller 305 is rotatably connected to the roller frame 304. Compression springs 303 are sleeved on the two column rods 302, and the two ends of the compression spring 303 are welded to the cross beam 301 and the roller frame 304 respectively;

[0021] Under the elastic force of two compression springs 303, a downward pressure is applied to the roller frame 304 and the pressure roller 305, so that the pressure roller 305 is elastically pressed on the flexible filter screen 201. The soil to be repaired is put onto the flexible filter screen 201 in the box body 101. The cross beam 301 slides left and right reciprocally in two notches 103, driving the pressure roller 305 to move left and right reciprocally. During the left and right reciprocal movement of the pressure roller 305, the pressure roller 305 is driven to rotate under the action of the frictional force in contact with the soil, thereby performing a roller crushing treatment on the soil. The soil after the crushing treatment is convenient to be in full contact with the soil repair agent, and thus the soil repair effect is better. The small granular soil after crushing is discharged from the filter holes on the flexible filter screen 201, and the large granular soil remains on the flexible filter screen 201 and continues to be roller crushed until it is discharged through the filter holes on the flexible filter screen 201;

[0022] Secondly, when the flexible filter screen 201 is in a tensioned state, the flexible filter screen 201 pushes the pressure roller 305 upward, so that the two compression springs 303 are compressed. The two compressed compression springs 303 give a greater reaction force to the roller frame 304 and the pressure roller 305, so that the acting force of the pressure roller 305 pressing on the flexible filter screen 201 is greater. Furthermore, when performing a reciprocating roller pressing on the soil on this basis, a greater roller crushing force can be provided to fully crush the caked soil and prevent the caked soil from not being fully broken due to too small a roller crushing force;

[0023] When the flexible filter screen 201 is in a relaxed state, the force of the pressure roller 305 pressing on the flexible filter screen 201 becomes smaller. Furthermore, the tension of the flexible filter screen 201 can be adjusted according to the caking degree of the soil, thereby changing the roller crushing force.

[0024] See Figures 3 to 4 , which shows a schematic diagram of an embodiment of changing the roller crushing force according to the present invention;

[0025] Two through slots 102 are symmetrically opened left and right on the box body 101. The two ends of the flexible filter screen 201 respectively pass through the two through slots 102. Frame 202 is fixedly connected to the outer ends of both ends of the flexible filter screen 201. Adjusting members for adjusting the distance between the two frames 202 are provided at both ends of the box body 101;

[0026] When the distance between the two frames 202 becomes larger, the flexible filter screen 201 is stretched and thus tensioned. When the distance between the two frames 202 becomes smaller, the flexible filter screen 201 is in a relaxed state, thereby changing the contact force between the pressure roller 305 and the flexible filter screen 201, and thus changing the roller crushing force.

[0027] See Figure 3 and 6 , which shows a schematic diagram of an embodiment of changing the distance between the two frames 202 on both sides according to the present invention;

[0028] The adjusting member includes guide rods 106 symmetrically fixed to both ends of the box body 101 by screws, and the two frames 202 are respectively slidably connected to the two guide rods 106;

[0029] The two frames 202 can slide on the two guide rods 106 respectively, thereby changing the distance between the frames 202 on both sides. The guide rods 106 play a guiding role in the sliding trajectory of the frames 202.

[0030] See Figure 3 and 6 , which shows a schematic diagram of an embodiment of changing the position of the frame 202 according to the present invention;

[0031] The adjusting member further includes screws 107 symmetrically rotatably connected to both ends of the box body 101, and the two frames 202 are respectively threadedly connected to the two screws 107;

[0032] By manually screwing the screw 107 to drive the frame 202 to move laterally, the frame 202 slides on the guide rod 106, thereby changing the position of the frame 202.

[0033] Furthermore, the flexible filter screen 201 is made of polypropylene, high-density polyethylene or polyurethane.

[0034] See Figure 5 , which shows a schematic diagram of an embodiment of improving the roller crushing effect according to the present invention;

[0035] A plurality of convex ridges are integrally formed around the pressure roller 305 evenly;

[0036] The plurality of convex ridges improve the roller crushing strength of the soil, thereby improving the roller crushing effect.

[0037] See Figure 3 , which shows a schematic diagram of an embodiment of driving the pressure roller 305 to move left and right reciprocally according to the present invention;

[0038] A motor 104 is fixedly connected to the left side of the box body 101. The output shaft of the motor 104 is connected to a lead screw 105 through a coupling. The lead screw 105 is rotatably connected to the box body 101, and the cross beam 301 is threadedly connected to the lead screw 105;

[0039] When the motor 104 is powered on and started, it drives the lead screw 105 to rotate. The lead screw 105 drives the cross beam 301 to move horizontally left and right reciprocally in the two notches 103, thereby driving the pressure roller 305 to move left and right reciprocally to perform roller crushing treatment on the soil.

[0040] See Figure 7 and 8 , which shows a schematic diagram of an embodiment of spraying the soil remediation agent according to the present invention;

[0041] A medicine spraying tank 306 is fixedly connected to the cross beam 301 by screws; a telescopic hose is connected to the upper end of the medicine spraying tank 306;

[0042] The soil conditioner is injected into the telescopic hose through an external high-pressure pipe and then flows into the medicine spraying tank 306. When the cross beam 301 moves reciprocally left and right, it drives the medicine spraying tank 306 to move synchronously left and right. The soil conditioner is sprayed out from both sides of the medicine spraying tank 306, and then sprayed onto the soil roller-compacted by the pressure roller 305, so that the finely crushed soil after roller compaction is in full contact with the soil conditioner;

[0043] The medicine spraying tank 306 is made of telescopic hose material, which is convenient for the telescopic hose to adapt when the cross beam 301 moves left and right.

[0044] See Figure 4 , which shows a schematic diagram of an embodiment for facilitating the disassembly and replacement of the flexible filter screen 201 according to the present invention;

[0045] The frame 202 and the flexible filter screen 201 are detachably connected by screws; thus, it is convenient to disassemble the flexible filter screen 201 for replacement.
