Description

Technical Field

[0001] The invention relates to the technical field of contaminated soil cleaning, in particular to a cleaning device for treating soil pollution. Background Art

[0002] Contaminated soil refers to soil that contains one or more substances that are harmful to biological or human health, or the content of these substances exceeds the self-purification capacity of the soil, resulting in changes in the chemical, physical or biological properties of the soil, thereby affecting the function of the soil. Using eluents to clean the soil is a common method for treating contaminated soil. Eluents can react with pollutants in the soil to form soluble pollutant ions or complexes, making it easier to separate pollutants from the soil;

[0003] In order to make the eluent fully clean the contaminated soil, crushing equipment is usually used to break up the soil blocks, and then the broken soil is put into the chemical tank for cleaning. The eluent inside the chemical tank reacts quickly with the broken soil to remove pollutants in the soil. During the soil crushing and refinement process, impurities such as plastics, stones, and packaging bags in the soil will also be broken, causing large-sized impurities to be broken into small-sized impurities. The small-sized impurities enter the subsequent chemical processing process with the soil, which can easily cause secondary pollution to the soil. Summary of the invention

[0031] Furthermore, the movable tube is slidably engaged with the shaft rod, and both sides of the top surface of the crossbeam are inclined surfaces.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. By putting the contaminated soil into the metal mesh bag and injecting the eluent into the medicine tank, the contaminated soil can be first immersed in the eluent with the help of the metal mesh bag. By arranging extrusion plates that can be moved to the metal mesh bag individually around the metal mesh bag, each group of two relatively arranged extrusion plates can successively and cyclically squeeze the contaminated soil inside the metal mesh bag. The extrusion plates squeeze the contaminated soil in multiple directions to crush the contaminated soil inside the metal mesh bag. The cleaned and crushed soil can fall to the bottom of the medicine tank through the mesh holes of the metal mesh bag. Impurities such as packaging bags, plastics, and stones in the soil are not easily crushed, so they are convenient to be retained in the metal mesh bag for subsequent collection, so that impurities in the soil can be cleaned out during the process of cleaning the contaminated soil, which is beneficial to improving the efficiency of cleaning impurities in the contaminated soil.

[0034] 2. By enclosing multiple extrusion plates around the metal mesh bag, the contaminated soil can be gathered in the stirring area of ​​the stirring rod. The shaft rod drives multiple stirring rods to rotate to further break up the soil, so that the soil can pass through the mesh of the metal mesh bag and be separated from the impurities. The rotation of the stirring rod also facilitates the full mixing and contact between the eluent and the soil, thereby improving the effect of soil cleaning;

[0035] 3. The motor drives two winding wheels to rotate and reel in the traction rope, so that the metal mesh bag can be moved up, or the motor drives two winding wheels to rotate and release the traction rope, so that the metal mesh bag can be moved down, thereby realizing flexible adjustment of the height position of the metal mesh bag, facilitating the traction and movement of the contaminated soil to a position between multiple extrusion plates according to the volume of the contaminated soil to be cleaned, so that the subsequent extrusion plates can fully crush the soil, and the bottom of the metal mesh bag can be moved up to the receiving box position by continuously reeling in the traction rope, so as to facilitate the centralized cleaning of impurities filtered out of the metal mesh bag.

[0036] 4. A guide block is provided on each extrusion mechanism, and a guide groove is opened on the guide block. When the screw rotates to drive the extrusion plate to extrude the soil, the top of the L-shaped rod used to drive the extrusion plate to move will move along the guide groove. By designing the guide groove into a plurality of bending patterns, the L-shaped rod can be kept from moving up and down during the linear movement, and the two relatively arranged guide grooves are respectively designed into patterns similar to "M" and "W", so that the two extrusion plates moving close to each other can move up and down alternately at the same time, so as to achieve the effect of dislocation extrusion of the soil, so as to fully crush the soil.

Detailed implementation mode

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] Example 1, please refer to Figure 1 - Fig. 9 In the embodiment of the present invention, a cleaning device for treating soil pollution includes a substrate 100. A U-shaped frame 110 and a receiving box 120 are fixed on the top of the substrate 100. A metal mesh bag 200 is fixedly connected and communicated at the bottom of the receiving box 120. Two towing ropes 210 are inserted through the outside of the metal mesh bag 200. The bottom ends of the towing ropes 210 are fixed to the bottom end of the metal mesh bag 200. A stirring mechanism 300 is arranged inside the metal mesh bag 200. A drive box 400 is fixed on the top of the U-shaped frame 110. A drive mechanism 410 is arranged inside the drive box 400. A medicine water tank 500预埋固定 in the ground is arranged below the substrate 100. The metal mesh bag 200 is arranged inside the medicine water tank 500. Extrusion mechanisms 600 are arranged on all four sides of the metal mesh bag 200. The extrusion mechanism 600 includes a lead screw 610 rotatably connected to the medicine water tank 500. An L-shaped rod 1 620 is screwed and driven on the outside of the lead screw 610. A guide block 630 is slidably clamped on the top of the L-shaped rod 1 620. An extrusion plate 640 is fixed at one end of the L-shaped rod 1 620.

[0049] It should be noted that there is an unclear expression "预埋固定" in the original text, which may need to be further clarified in the actual context for more accurate translation.Specifically, the contaminated soil is contained in a flexible and deformable metal mesh bag 200, and the metal mesh bag 200 is immersed in the medicine tank 500 with the soil, so as to achieve the effect of immersing and washing the contaminated soil with medicine. The two squeezing plates 640 arranged relatively around the metal mesh bag 200 can successively squeeze the soil in an offset manner, so as to facilitate crushing the contaminated soil. The multiple squeezing plates 640 can enclose the metal mesh bag 200 within the stirring range of the stirring rod 331, and the multiple stirring rods 331 can further crush the soil, so that the soil is fully contacted with the eluent for purification, and it is also convenient to fully crush the soil so that it can pass through the mesh holes of the metal mesh bag 200 and fall to the bottom of the medicine tank 500. Impurities such as plastics, stones, and packaging bags that are not easy to be squeezed and crushed are retained in the metal mesh bag 200, so as to realize the cleaning of impurities in the contaminated soil, which is conducive to improving the efficiency of cleaning impurities in the contaminated soil. Compared with the current use of crushing equipment to crush the soil, the impurities in the soil will not be crushed together, which effectively prevents large-sized impurities from being crushed into small-sized impurities that enter the subsequent chemical processing flow with the soil to cause secondary pollution.

[0050] like Figure 2 As shown, in the present embodiment, the receiving box 120 is an annular structure. When the metal mesh bag 200 is moved up to the bag opening, the impurities intercepted inside the metal mesh bag 200 can be moved around nearby. The annular receiving box 120 can receive impurities from different directions. A support ring 121 is fixed at the inner ring position of the receiving box 120. The support ring 121 is fixed to the bag opening of the metal mesh bag 200 so that the bag opening is in an open state. The pipe for transporting soil from the outside is facing the bag opening, which facilitates the transport of the contaminated soil to be cleaned into the metal mesh bag 200.

[0051] In this embodiment, the material of the metal mesh bag 200 can be the steel wire material of the steel wire gloves in the prior art, so that the metal mesh bag 200 can produce adaptive deformation during the extrusion process, which is conducive to crushing the soil. The mesh holes on the metal mesh bag 200 can allow the crushed soil to pass through, and intercept large-sized impurities in the soil inside the metal mesh bag 200.

[0052] like Figure 1 As shown, in this embodiment, the substrate 100 is on the ground, the medicine tank 500 and the conveying mechanism 700 are both underground. When installing the cleaning equipment, a foundation pit can be opened on the ground in advance, the inside of the foundation pit is cast and fixed with concrete, and then the substrate 100 is fixed on the top of the foundation pit, and the medicine tank 500 and the conveying mechanism 700 are both installed and fixed inside the foundation pit.

[0053] like Figure 1 and Figure 2As shown, in this embodiment, the driving mechanism 410 includes a motor 1 411 and a motor 2 413 fixedly connected to the driving box 400, and a connecting shaft is fixed to the output end of the motor 1 411. Two winding wheels 412 are fixedly sleeved on the outer side of the connecting shaft. The winding wheels 412 are wound and fixed with the traction rope 210 at the corresponding position. When the motor 1 411 drives the winding wheel 412 to rotate and reel in the traction rope 210, the metal mesh bag 200 can be continuously moved upward, thereby facilitating the transfer of impurities inside the metal mesh bag 200 to the position of the receiving box 120 and collecting them inside the receiving box 120.

[0054] In this embodiment, motor 2 413 can drive the shaft 320 to rotate to make the stirring mechanism 300 operate. A rotating seat 414 is fixed on the top of motor 2 413, and the connecting shaft is rotatably connected to the rotating seat 414, so that the connecting shaft drives the winding wheel 412 to rotate stably at the output end of motor 1 411.

[0055] like Figure 4 and Figure 6 As shown, in the present embodiment, the extrusion mechanism 600 further includes a motor three 650 fixedly connected to the outer side of the medicine box 500, the output end of the motor three 650 is fixedly connected to the corresponding position screw rod 610, the extrusion mechanism 600 further includes an L-shaped rod two 670 fixedly connected to the inner side of the medicine box 500, one end of the L-shaped rod two 670 is rotatably connected to the screw rod 610, the outer side of the screw rod 610 is screwedly connected with a transmission block 611, the L-shaped rod one 620 is slidably connected with the transmission block 611, the outer side of the guide block 630 is provided with a guide groove 631 transmission-connected to the L-shaped rod one 620, and one end of the L-shaped rod one 620 is rotatably provided with a roller 660 rollingly connected to the guide groove 631.

[0056] During specific implementation, motor three 650 drives screw rod 610 to rotate so that transmission block 611 screwed therewith moves toward metal mesh bag 200, and transmission block 611 drives L-shaped rod one 620 to move in the same direction, thereby making L-shaped rod one 620 drive extrusion plate 640 to squeeze metal mesh bag 200. When two relatively arranged extrusion plates 640 squeeze and approach metal mesh bag 200 at the same time, soil inside metal mesh bag 200 can be crushed. Extrusion plates 640 in different directions can squeeze soil from different directions, so as to fully crush soil. During the movement of L-shaped rod one 620, the top of L-shaped rod one 620 slides along multiple bent guide grooves 631, so that L-shaped rod one 620 can move back and forth up and down during lateral movement, so that extrusion plate 640 can be slightly displaced up and down during lateral extrusion of soil, so as to achieve the effect of dislocation extrusion of soil by relatively arranged two extrusion plates 640.

[0057] like Figure 6As shown, in this embodiment, a rubber plate 641 is fixed to one side of the extrusion plate 640 , so that the extrusion plate 640 is in flexible contact with the metal mesh bag 200 , which is beneficial to protecting the woven connection position of the metal mesh bag 200 .

[0058] like Figure 6 and Figure 7 As shown, in this embodiment, a limiting wheel 661 is fixed at one end of the roller 660 and is rollingly engaged with the guide groove 631 , so that the roller 660 will not be separated from the guide block 630 during the rolling process inside the guide groove 631 .

[0059] like Figure 1 As shown, in the present embodiment, two water pipes are connected and fixed on one side of the medicine water tank 500. The water pipe at the top of the medicine water tank 500 is used to transport eluent or water to the medicine water tank 500, and the water pipe at the bottom of the medicine water tank 500 is used to pump water inside the medicine water tank 500. Both water pipes are connected to external pipes for pumping or sucking water. The specific connection of the pipes is the existing technology, and the working principle will not be described in detail.

[0060] like Figure 2 As shown, in this embodiment, a connecting bucket 510 is fixedly connected to the bottom of the medicine water box 500, and the connecting bucket 510 can guide and transport a small amount of water retained at the bottom of the medicine water box 500 and the soil after rinsing to the conveying mechanism 700, wherein a valve 511 is installed under the connecting bucket 510, and when it is necessary to clean the settled soil, the valve 511 is opened, and then the conveying mechanism 700 is used to transport the soil, and a vibration motor in the prior art can be installed on the outside of the connecting bucket 510, so that the settled soil inside the connecting bucket 510 can fall quickly.

[0061] like Figure 2 As shown, in this embodiment, a plurality of circular holes 130 are formed through the bottom surface of the substrate 100 , and the circular holes 130 are connected to the chemical tank 500 below the substrate 100 , and different contaminated soil treatment agents can be added into the chemical tank 500 through the circular holes 130 .

[0062] like Figure 5 and Figure 8 As shown, in this embodiment, the stirring mechanism 300 includes a beam 310 fixedly connected to the bottom of the medicine box 500, the top of the beam 310 is rotatably connected to the shaft rod 320, the outer side of the shaft rod 320 is slidably clamped with a movable tube 330, and a plurality of stirring rods 331 are fixed at equal intervals on the outer side of the movable tube 330.

[0063] During specific implementation, the output end of motor 2 413 drives the shaft 320 to rotate, and the shaft 320 drives the movable tube 330 on its outside to rotate, and the movable tube 330 drives the stirring rod 331 on its outside to rotate to further break up the soil, wherein the stirring rod 331 is not a crushing blade and will not refine impurities. At the same time, the end of the stirring rod 331 is set to a hemispherical shape, and the outer side of the traction rope 210 is inserted and tensioned inside the metal mesh bag 200 to prevent the end of the stirring rod 331 from rotating and driving the traction rope 210 to move.

[0064] In this embodiment, when two relative extrusion plates 640 move toward each other, the shaft 320 can rotate with the plurality of stirring rods 331 to a position parallel to the surface of the extrusion plates 640, thereby preventing the stirring rods 331 from obstructing the two relative extrusion plates 640 from moving toward each other.

[0065] like Figure 8 As shown, in this embodiment, the movable tube 330 is slidably engaged with the shaft rod 320, so that the rotation of the shaft rod 320 can drive the movable tube 330 to rotate with multiple stirring rods 331. During the upward movement of the metal mesh bag 200, the metal mesh bag 200 can slide upward along the shaft rod 320 with the movable tube 330, so that the movable tube 330 and the stirring rod 331 will not interfere with the upward movement of the metal mesh bag 200, wherein the shaft rod 320 passes through the metal mesh bag 200.

[0066] like Figure 8 As shown, in this embodiment, both sides of the top surface of the beam 310 are inclined surfaces, which can reduce the residual soil on the top surface of the beam 310 to a certain extent.

[0067] like Figure 8 As shown, in this embodiment, a slot is provided on the outer side of the shaft rod 320 , and a block is fixed on the inner side of the movable tube 330 slidably engaged with the slot, so that the movable tube 330 can be slidably engaged with the outer side of the shaft rod 320 .

[0068] Embodiment 2, based on embodiment 1, is to transport the soil dropped from the bottom of the medicine water tank 500 out.

[0069] like Figure 1 and Figure 2 As shown, in this embodiment, a conveying mechanism 700 is arranged below the medicine tank 500, and the conveying mechanism 700 includes a mud conveying pipe 710 connected and fixed to the connecting bucket 510, wherein one end of the mud conveying pipe 710 is sealed, and an auger 720 is rotatably connected inside the mud conveying pipe 710, and a motor 4 730 is installed and fixed at the sealed end of the mud conveying pipe 710, and the motor 4 730 is used to drive the auger 720 to rotate.

[0070] During the specific implementation, the valve 511 on the connecting bucket 510 is opened to allow the soil and a small amount of water inside the connecting bucket 510 to flow into the mud conveying pipe 710, wherein the mud conveying pipe 710 is connected to the foundation pit outside that contains the washed soil, and the motor 4 730 drives the auger 720 to rotate to transport the soil inside the mud conveying pipe 710 into the foundation pit, thereby cleaning the soil that has settled to the connecting bucket 510.

[0071] In the present invention, if Fig. 9 As shown, when the contaminated soil to be cleaned is clay-type, stirring is usually not recommended, and when the clay content in the soil reaches a certain proportion (such as 25% to 30%), stirring may cause soil particles to agglomerate or clump, reducing the cleaning effect. At this time, the movable tube 330 and the stirring rod 331 can be installed on the shaft 320, and the soil can be refined only by the offset extrusion of the extrusion plate 640. The outer side of the traction rope 210 used to tow the metal mesh bag 200 can no longer be inserted into the metal mesh bag 200, but directly fixed to the inner bottom surface of the metal mesh bag 200. After the soil leaching and refinement is completed, the traction rope 210 can also be used to pull the metal mesh bag 200 upward. At this time, the traction rope 210 can flip the inner bottom of the metal mesh bag 200 out to automatically dump the impurities inside the metal mesh bag 200.

[0072] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0073] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
