Description

Technical Field

[0001] The invention relates to the technical field of soil remediation equipment, and in particular to a soil leaching and remediation system. Background Art

[0002] At present, most of the contaminated soil is repaired by showering. There are usually two types of shower remediation methods, one is the in-situ shower remediation method, and the other is the ex-situ shower remediation method. The ex-situ shower remediation method refers to digging the contaminated soil from the ground, and after simple screening and impurity removal, it is transported to the corresponding spraying equipment, and the chemical solution is used to contact the heavy metals and petroleum pollution components in the soil by spraying. After the purification is completed, the soil is backfilled.

[0003] In the prior art, the invention patent with the announcement number CN114405983B provides a contaminated soil remediation device based on ex situ chemical leaching, including a base and a containing box, the first transverse cylinder rotatably mounted inside the base is unidirectionally mounted on the right end of the rotating shaft through a one-way bearing, and the rotating shaft located inside the base is connected to the first motor, and the second transverse cylinder is also unidirectionally mounted on the rotating shaft. When in use, the target amount of soil is loaded into the containing box, and the purpose of soil remediation is achieved by spraying the remediation liquid on the soil loaded in the containing box.

[0004] However, the soil deposited in the containing box cannot fully contact with the repair liquid, resulting in a poor repair effect. In addition, since the repair liquid that the soil located above contacts is the repair liquid that has not yet contacted the soil, and the repair liquid that the soil located below contacts is the repair liquid that has already acted on the soil located above, it is easy to cause inconsistent repair effects on different layers of soil. Summary of the invention

[0005] In view of the defects in the prior art, the object of the present invention is to provide a soil leaching and remediation system to solve or alleviate the above-mentioned technical problems existing in the prior art.

[0006] In order to achieve the above object, the present invention provides a soil leaching and remediation system, comprising a frame, a remediation box is arranged on the frame, the remediation box has a receiving cavity for accommodating soil and remediation liquid, a spray device is arranged above the remediation box, the spray device is used to spray the remediation liquid into the remediation box, and also includes:

[0047] like Figure 1-10 As shown, the present invention provides a soil leaching and remediation system, including a frame 100, on which a remediation box 200 is arranged, the remediation box 200 has a containing chamber 210 for containing soil and remediation liquid, and a spraying device 300 is arranged above the remediation box 200, and the spraying device 300 is used to spray the remediation liquid into the remediation box 200. In the working state, a preset amount of soil to be remediated is transported into the remediation box 200, and the remediation liquid is sprayed into the remediation box 200 through the spraying device 300, and under the action of the remediation liquid, the purpose of remediating the soil in the remediation box 200 is achieved. These are all prior arts, and will not be elaborated on here.

[0048] like Figure 1 , 2 As shown in Figures 3, 4 and 5, in this embodiment, the soil leaching and remediation system also includes a mixing device and a driving device.

[0049] The mixing device is arranged in the repair box 200, and the mixing device is rotatably connected to the repair box 200. The driving device is in transmission connection with the mixing device. In the working state, the driving device drives the mixing device to rotate, so that the soil or the mixture of soil and the repair liquid flows in the repair box 200, so that the repair liquid is fully in contact with the soil, thereby achieving the purpose of improving the repair effect.

[0050] Specifically, when a filter plate is provided at the bottom of the accommodating chamber 210, the repair liquid sprayed by the spray device 300 flows out through the filter plate after contacting the soil, thereby achieving the purpose of repairing the soil. In this process, the driving device drives the mixing device to rotate in the repair box 200, so that the soil flows in the repair box 200, so that the soil in the repair box 200 can fully contact with the repair liquid, thereby achieving the purpose of improving the repair effect and maintaining basically consistent repair of all soils.

[0051] When the bottom of the receiving chamber 210 is sealed, the spraying device 300 sprays a preset amount of repair liquid into the receiving box. At the same time, the driving device drives the mixing device to rotate in the repair box 200, so that the soil and the repair liquid flow in the repair box 200, so that the soil and the repair liquid in the repair box 200 are fully in contact and interact with each other, thereby achieving the purpose of improving the repair effect and maintaining basically consistent repair of all soils.

[0052] like Figure 1 , 2As shown in Figure 3, in one embodiment, the mixing device includes a rotating shaft 410 and a stirring element 420 disposed on the rotating shaft 410, and the rotating shaft 410 is rotatably connected to the repair box 200. The driving device is in transmission connection with the rotating shaft 410. In the working state, the driving device drives the rotating shaft 410 to rotate, thereby driving the stirring element 420 to rotate, thereby achieving the purpose of making the soil in the repair box 200 or the mixture of soil and repair liquid flow in the repair box 200.

[0053] like Figure 4 , 5 As shown, the stirring element 420 can be a stirring rod or a stirring paddle.

[0054] Specifically, in one embodiment, the mixing device includes a rotating shaft 410 and a paddle 430 disposed on the rotating shaft 410. The rotating shaft 410 is rotatably connected to the repair box 200. The driving device is in transmission connection with the rotating shaft 410. In a working state, the driving device drives the rotating shaft 410 to rotate, and the rotating shaft 410 drives the paddle 430 to rotate, thereby generating a pressure difference in the repair box 200, thereby achieving the purpose of making the mixture of the repair liquid and the soil in the repair box 200 flow in the repair box 200.

[0055] like Figure 4 , 5 As shown, in this embodiment, the soil leaching and remediation system also includes a drain 500, which is hollow and open at both ends. The side wall of the drain 500 is provided with a plurality of drainage holes 510. The drain 500 is arranged in the remediation box 200 and is sleeved outside the mixing device. In the working state, the driving device drives the mixing device to rotate in the remediation box 200 to form a pressure difference, so that the soil and the remediation liquid circulate inside and outside the drain 500. During the circulation of the soil and the remediation liquid inside and outside the drain 500, the soil will not be deposited in the remediation box 200. At the same time, all the soil can fully contact with the remediation liquid, thereby further achieving the purpose of improving the remediation effect.

[0056] Specifically, Figure 4 , 5 As shown, the drain 500 is fixedly connected to the inner wall of the repair box 200 through a bracket. The bracket includes an inner ring, an outer ring and a plurality of connecting rods connected between the inner ring and the outer ring. The inner ring is sleeved on the drain 500. The outer ring is fixedly connected to the inner wall of the repair box 200.

[0057] like Figure 1 , 2 As shown in Figures 3, 4 and 5, in this embodiment, the driving device includes a transmission shaft 610 and a first motor 620.

[0058] The transmission shaft 610 is rotatably connected to the frame 100, and the power output end of the transmission shaft 610 is transmission-connected to the mixing device (i.e., the rotating shaft 410). The first motor 620 is fixedly connected to the frame 100, and the power output shaft of the first motor 620 is transmission-connected to the mixing device.

[0059] like Figure 2 , 3 5, specifically, in this embodiment, the axis of the transmission shaft 610 extends in the horizontal direction, and the axis of the rotating shaft 410 extends in the longitudinal direction. The rotating shaft 410 is sleeved with a first bevel gear, and the first end of the transmission shaft 610 is sleeved with a second bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0060] A third bevel gear is sleeved on the second end of the transmission shaft 610 , a fourth bevel gear is sleeved on the power output shaft of the first motor 620 , and the third bevel gear is meshed with the fourth bevel gear.

[0061] When in use, the first motor 620 drives the transmission shaft 610 to rotate, thereby driving the mixing device to rotate.

[0062] like Figure 1 , 2 As shown in Figures 3, 4 and 5, in this embodiment, the soil leaching and remediation system also includes a mounting frame 700, a locking device and a clutch device.

[0063] The mounting frame 700 is rotatably connected to the frame 100, and the mounting frame 700 is sleeved on the transmission shaft 610 and rotatably connected to the transmission shaft 610. The mounting frame 700 has a first position and a second position, and the repair box 200 is mounted on the mounting frame 700 and can move with the mounting frame 700. The mounting frame 700 is placed in the first position so that the opening of the repair box 200 faces upward, and the mounting frame 700 is placed in the second position so that the opening of the repair box 200 faces downward, so as to achieve the purpose of pouring out the mixture of soil and repair liquid in the repair box 200. It should be noted that the opening of the repair box 200 facing downward mentioned here can be either inverting the repair box 200 so that the opening of the repair box 200 faces downward, or tilting the repair box 200 so that the opening of the repair box 200 faces downward.

[0064] The locking device is arranged on the frame 100 and the mounting frame 700. In the working state, the locking device is placed in a locked state so that the mounting frame 700 cannot rotate. In the non-working state, the unlocking assembly is placed in an unlocked state so that the mounting frame 700 can rotate back and forth between the first position and the second position.

[0065] like Fig.10 As shown, in this embodiment, the locking device includes a locking socket 810 , a locking pin 820 and a second drive assembly 830 .

[0066] The locking socket 810 is provided on the mounting frame 700. The locking latch 820 is provided on the frame 100 and is slidably connected to the frame 100. The locking latch 820 has a fifth position and a sixth position. When the locking latch 820 is in the fifth position, the locking latch 820 is located outside the locking socket 810, so that the locking device is in an unlocked state. When the locking latch 820 is in the sixth position, the locking latch 820 is inserted into the locking socket 810, so that the locking device is in a locked state.

[0067] The second driving assembly 830 is fixedly mounted on the frame 100, and the second driving assembly 830 is in transmission connection with the locking latch 820. In the working state, the second driving assembly 830 drives the locking latch 820 to the fifth position, thereby placing the locking device in the unlocked state, and the second driving assembly 830 drives the locking latch 820 to the sixth position, thereby placing the locking device in the locked state.

[0068] Specifically, in one embodiment, the second driving assembly 830 includes an automatic telescopic device, such as an electric push rod, a cylinder or a hydraulic cylinder. The automatic telescopic device is fixedly mounted on the frame 100, and the power output shaft locking pin 820 of the automatic telescopic device is fixedly connected.

[0069] The clutch device is arranged on the mounting frame 700 and the transmission shaft 610. In the working state, the clutch device is placed in the engaged state (that is, the transmission shaft 610 can transmit power to the mounting frame 700) so that the first motor 620 can drive the mounting frame 700 to rotate. In the non-working state, the clutch device is placed in the disengaged state (that is, the transmission shaft 610 cannot transmit power to the mounting frame 700) so that the first motor 620 cannot drive the mounting frame 700 to rotate.

[0070] When in use, the clutch device is placed in a coupled state, the first motor 620 drives the transmission shaft 610 to rotate, and the rotating shaft drives the mounting bracket 700 to rotate, thereby achieving the purpose of driving the mounting bracket 700 to reciprocate between the first position and the second position.

[0071] like Figure 6 , 7 As shown in FIGS. 8 and 9 , in this embodiment, the clutch device includes a clutch block 910 and a first drive assembly 920 .

[0072] There are two clutch blocks 910, which are arranged opposite to each other and slidably connected to the mounting frame 700, and grooves adapted to the transmission shaft 610 are provided on opposite sides of the two clutch blocks 910, and the clutch blocks 910 have a third position and a fourth position.

[0073] The first driving assembly 920 is disposed on the mounting frame 700, and is in driving connection with the clutch block 910. The first driving assembly 920 is used to drive the clutch block 910 to perform reciprocating linear motion between the third position and the fourth position. In the working state, the first driving assembly 920 places the clutch block 910 in the fourth position, so that the side wall of the groove contacts the side wall of the transmission shaft 610, so that the transmission shaft 610 can transmit power to the mounting frame 700. In the non-working state, the first driving assembly 920 places the clutch block 910 in the third position, so that the side wall of the groove is separated from the side wall of the transmission shaft 610, so that the transmission shaft 610 cannot transmit power to the mounting frame 700.

[0074] When in use, the first driving assembly 920 drives the clutch block 910 to move to the fourth position, so that the two clutch blocks 910 are close to each other, and then the side wall of the groove is in conflict with the side wall of the transmission shaft 610. At this time, the first motor 620 drives the transmission shaft 610 to rotate, and the transmission shaft 610 drives the mounting frame 700 to rotate through the clutch block 910, so as to achieve the purpose of driving the mounting frame 700 to reciprocate between the first position and the second position.

[0075] The first driving assembly 920 drives the clutch block 910 to move to the third position, so that the two clutch blocks 910 move away from each other, thereby separating the side wall of the groove from the side wall of the transmission shaft 610. At this time, the first motor 620 drives the transmission shaft 610 to rotate, and the rotating shaft drives the mixing device to rotate.

[0076] like Figure 6 , 7 As shown, in one embodiment, the first driving assembly 920 includes an automatic telescopic device, such as an electric push rod, a cylinder or a hydraulic cylinder. The automatic telescopic device is fixedly mounted on the frame 100, and the power output shaft of the automatic telescopic device is fixedly connected to the clutch block 910.

[0077] like Figure 8 , 9 As shown, in one embodiment, the first drive assembly 920 includes a lead screw, a nut, and a second motor.

[0078] The lead screw is rotatably connected to the mounting frame 700. The lead screw has two external thread segments with the same pitch but opposite spiral directions. A nut is sleeved on the lead screw, and two nuts are provided. The two nuts are respectively threadedly connected to the lead screw through the two external thread segments, so that when the lead screw rotates, the two nuts can move closer to or farther from each other, and the two nuts are respectively fixedly connected to the two clutch blocks 910. The second motor is transmission-connected to the lead screw.

[0079] When in use, the second motor drives the lead screw to rotate in the forward direction, so that the two nuts approach each other, and then the side wall of the groove contacts the side wall of the transmission shaft 610, so that the clutch device is in a engaged state.

[0080] The second motor drives the lead screw to rotate in the opposite direction, so that the two nuts move away from each other, and then the side wall of the groove is separated from the side wall of the transmission shaft 610, so that the clutch device is in a disengaged state.

[0081] like Figure 6 , 7 As shown in FIGS. 8 and 9 , preferably, the side wall of the groove and the side wall of the transmission shaft 610 are provided with mutually matching limiting teeth to achieve the purpose of improving the reliability of power transmission between the transmission shaft 610 and the clutch block 910 .

[0082] like Figure 11-12 As shown, in this embodiment, the soil leaching and remediation system also includes a detection component, which is arranged on the frame 100 and / or the mounting frame 700. The detection component is used to detect the position of the mounting frame 700. In the working state, when the detection component detects that the mounting frame 700 moves from the second position to the first position, the first motor 620 stops and the clutch assembly is converted from the engaged state to the separated state. When the detection component detects that the mounting frame 700 moves to the second position, the first motor 620 stops.

[0083] like Fig.11 As shown, specifically, in one embodiment, the detection component includes a sensing sheet 101 and a sensor 102. Among them, one of the sensing sheet 101 or the sensor 102 is arranged on the mounting frame 700, and the other is arranged on the frame 100, and there are two sensing sheets 101. When one of the sensing sheets 101 corresponds to the sensor 102, it means that the mounting frame 700 is in the first position, and when the other sensing sheet 101 corresponds to the sensor 102, it means that the mounting frame 700 is in the second position.

[0084] like Fig.12 As shown, the detection assembly includes a sensing sheet 101 and a sensor 102. One of the sensing sheet 101 and the sensor 102 is arranged on the mounting frame 700, and the other is arranged on the frame 100, and two sensors 102 are arranged. When one of the sensors 102 corresponds to the sensing sheet 101, it means that the mounting frame 700 is in the first position, and when the other sensor 102 corresponds to the sensing sheet 101, it means that the mounting frame 700 is in the second position.

[0085] Of course, in other embodiments of the soil leaching and remediation system provided by the present invention, a filtering device may also be included to separate the remediation liquid and the soil.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
