Abstract
Description
Technical Field
[0001] The present application relates to the technical field of soil remediation equipment, and particularly relates to a heavy metal contaminated soil remediation treatment equipment and a treatment method. Background Art
[0002] Soil remediation is a technical measure that uses one or more of physical, chemical, or biological means to restore contaminated soil to its normal function. Among them, soil is an important material basis for human social production activities.
[0003] Among them, spraying a remediation agent on the contaminated soil is one of the important means of soil remediation. However, in the existing technical means, when spraying the remediation agent, either it is directly sprayed on the soil surface, resulting in most of the remediation agent being washed away by rain or evaporated by the sun and being easily lost, leading to a poor remediation effect on the contaminated soil, or a plow blade is used to perform soil loosening operation first, and then the remediation agent is sprayed onto the soil. However, the loose soil accelerates the penetration of the remediation agent, resulting in a large difference in the remediation effect between the deep soil and the surface soil, poor uniformity, and low stability and reliability.
[0004] Therefore, there is an urgent need for a remediation agent spraying device for soil remediation to solve the defects existing in the above-mentioned existing technical means when spraying the remediation agent. Summary of the Invention
[0005] The present application provides a heavy metal contaminated soil remediation treatment equipment and a treatment method, which have the advantages of being able to spray the remediation agent into the soil without destroying the soil structure, making the sprayed remediation agent not easily lost, and having a high consistency in the remediation of deep soil and surface soil and a good remediation effect. It is used to solve the problem that in the existing technical means, when spraying the remediation agent, either it is directly sprayed on the soil surface, resulting in most of the remediation agent being washed away by rain or evaporated by the sun and being easily lost, leading to a poor remediation effect on the contaminated soil, or a plow blade is used to perform soil loosening operation first, and then the remediation agent is sprayed onto the soil. However, the loose soil accelerates the penetration of the remediation agent, resulting in a large difference in the remediation effect between the deep soil and the surface soil.
[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a heavy metal contaminated soil remediation and treatment equipment, including a connecting rod with two ends fixedly mounted on a traction frame, a guide hole with one end extending to the outside thereof is provided inside the connecting rod, and one end of the guide hole is connected to the remediation agent delivery system, and the remediation agent is extruded and delivered to the inner cavity of the connecting rod, a transmission sleeve is movably sleeved on the outer surface of the connecting rod, and a pulley group connected to the driving motor on the traction mechanism is fixedly sleeved on one side of the outer surface of the transmission sleeve, and then the transmission sleeve can be driven to rotate under the power output of the driving motor, and a plurality of groups of plow wheels arranged in a linear array are provided on the outer surface of the transmission sleeve, and when spraying the remediation agent During the process, a part of the plow wheel is sunk into the soil, an eccentric disk is provided inside the connecting rod and at a position corresponding to the plow wheel, and a plurality of groups of elastic plugs are provided inside the transmission sleeve and are arranged in a circular array with the center of the eccentric disk, and under the action of the plurality of groups of elastic plugs, a plurality of groups of closed chambers are formed in the inner cavity of the transmission sleeve, and then when the transmission sleeve rotates, under the eccentric action of the eccentric disk, the plurality of closed chambers formed by the plurality of groups of elastic plugs change in size regularly, and a connecting hole connecting the outer surface of the eccentric disk and the guide hole is provided inside the eccentric disk, and a diversion hole connected to the inner wall of the transmission sleeve is provided inside the transmission sleeve, and the other end of the diversion hole is diverted to both sides of the outer surface of the plow wheel.
[0007] Furthermore, the central axis of the eccentric disk is located on the right side of the central axis of the transmission sleeve, and under the transmission action of the pulley group, the transmission sleeve rotates counterclockwise, thereby ensuring that the volume of the closed chamber located at the lower position can change from large to small, and allowing the plow wheel located directly below that is sunk into the soil to spray the repair agent.
[0008] Furthermore, the cross section of the diversion end of the diversion hole is set to a T-shaped structure to increase the effective coverage of the diversion hole when spraying the repair agent.
[0009] Furthermore, an elastic rubber sealing pad is provided at the bottom end of the diverter hole, so that when the diverter hole contacts the outer surface of the eccentric disk, the shape of the elastic rubber sealing pad at the bottom end of the diverter hole is elastically deformed during the process of the diverter hole changing its rotational position, and it can fit tightly with the outer surface of the eccentric disk to ensure the sealing of the closed chamber.
[0010] Furthermore, a one-way valve is provided inside the diversion hole and inside the transmission sleeve, thereby preventing external dust and other particulate impurities from entering the closed chamber through the diversion hole when the volume of a closed chamber changes from small to large, and causing blockage of the internal pipeline.
[0011] Further, it also includes an adjustment component between two groups of plow blade wheels. The adjustment component is an airbag fixedly installed on the outer surface of the transmission sleeve. The airbag is provided in three groups and fixedly connected through a bracket, and a support wheel is fixedly sleeved on the outer surface of the airbag. Furthermore, by adjusting the gas filling amount in the three airbags, eccentricity occurs between the support wheel and the transmission sleeve, thereby adjusting the height difference between the bottom end of the outer surface of the support wheel and the bottom end of the plow blade wheel directly below to control the depth of the plow blade wheel sinking into the soil, and effectively improving the applicability of the device.
[0012] A method for repairing and treating heavy metal contaminated soil includes the following operating steps:
[0013] S1. Connect the repair agent delivery system connected to the diversion holes, and adjust the gas filling amount in the airbag according to the characteristics of the soil, thereby adjusting the depth of the plow blade wheel located directly below sinking into the soil. Then, control the traction frame to lower the connecting rod and ensure that the bottom end of the support wheel contacts the soil surface;
[0014] S2. Start the drive motor and, under the drive of the belt pulley set, drive the transmission sleeve and the plow blade wheels thereon to perform a counterclockwise rotation action. Furthermore, under the action of the eccentric disc, the volume of the closed chamber located in the upper position becomes larger from smaller, and the volume of the closed chamber located in the lower position becomes smaller from larger;
[0015] S21. When the volume of a certain closed chamber becomes larger from smaller, the pressure inside it becomes smaller. Under the action of negative pressure adsorption, the repair agent in the diversion hole can enter the closed chamber in the upper position through the communication hole;
[0016] S22. When the volume of a certain closed chamber becomes smaller from larger, under the extrusion action of the elastic plug at the corresponding position, the repair agent in the closed chamber is sprayed out through the diversion holes on the plow blade wheel that is located in the lower position and sinks into the soil;
[0017] S3. Furthermore, under the traction of the traction mechanism, the device continuously moves forward. At the same time, the drive motor also drives the transmission sleeve and the plow blade wheels thereon to continuously perform a counterclockwise rotation action to spray the repair agent inside the soil.
[0018] The beneficial effects of the present invention are as follows:
[0019] A heavy metal contaminated soil remediation treatment device and treatment method provided by the present application, with the setting of a transmission sleeve and an eccentric disc, under the action of its eccentric drive, can make the sizes of several closed chambers formed by several groups of elastic plugs change regularly. Then, without destroying the soil structure, the remediation agent can be sprayed into the soil interior, so that the sprayed remediation agent is not easily lost, and the penetration of the remediation agent will not be accelerated due to the looseness of the soil, making the consistency of the remediation of deep soil and surface soil relatively high and the remediation effect better.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the 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 of 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 fall within the protection scope of the present invention.
[0028] As Figure 1 、 Figure 2As shown in the figure, a heavy metal contaminated soil remediation and treatment device includes a connecting rod 1 fixedly installed at both ends on a towing frame. A diversion hole 2 is provided inside the connecting rod 1, and one end of the diversion hole 2 extends to the outside of the connecting rod 1. One end of the diversion hole 2 is communicated with a remediation agent delivery system, and the remediation agent is extruded and delivered into the inner cavity of the connecting rod 1. A transmission sleeve 3 is movably sleeved on the outer surface of the connecting rod 1, and a pulley group 4 drivingly connected to a driving motor on a towing mechanism is fixedly sleeved on one side of the outer surface of the transmission sleeve 3. Thus, under the power output of the driving motor, the transmission sleeve 3 can be driven to rotate. A plurality of plow blade wheels 6 are arranged in a linear array on the outer surface of the transmission sleeve 3. During the process of spraying the remediation agent, a part of the plow blade wheels 6 sinks into the soil, as Figure 3 、 Figure 4 shown, an eccentric disk 5 is provided inside the connecting rod 1 at a position corresponding to the plow blade wheels 6. A plurality of elastic plugs 8 are arranged in a circular array with the center of the eccentric disk 5 as the center inside the transmission sleeve 3. Under the action of the plurality of elastic plugs 8, a plurality of sealed chambers are formed in the inner cavity of the transmission sleeve 3. Thus, when the transmission sleeve 3 rotates, under the eccentric action of the eccentric disk 5, the volumes of the plurality of sealed chambers formed by the plurality of elastic plugs 8 change regularly in size. A communication hole 9 communicating the outer surface of the eccentric disk 5 with the diversion hole 2 is provided inside the eccentric disk 5, and a diversion hole 10 communicating to the inner wall of the transmission sleeve 3 is provided inside the transmission sleeve 3. The other end of the diversion hole 10 is branched to both sides of the outer surface of the plow blade wheels 6;
[0029] Thus, when the volume of a certain sealed chamber changes from small to large, the pressure inside it becomes smaller. Under the action of negative pressure adsorption, the remediation agent in the diversion hole 2 can enter the corresponding sealed chamber through the communication hole 9;
[0030] When the volume of a certain sealed chamber changes from large to small, under the extrusion action of the elastic plug 8 at the corresponding position, the remediation agent in the sealed chamber can be sprayed out through the diversion hole 10 at the corresponding position.
[0031] As Figure 1 、 Figure 3 and Figure 4 shown, in this technical solution, the central axis of the eccentric disk 5 is located on the right side of the central axis of the transmission sleeve 3. Under the driving action of the pulley group 4, the transmission sleeve 3 rotates counterclockwise, thus ensuring that the volume of the sealed chamber in the lower position can change from large to small, and enabling the plow blade wheels 6 in the directly lower position that sink into the soil to perform the operation of spraying the remediation agent.
[0032] As Figure 5 shown, in this technical solution, the cross-section of the branched end of the diversion hole 10 is set as a T-shaped structure to improve the effective coverage range of the diversion hole 10 when spraying the remediation agent.
[0033] In this technical solution, an elastic rubber gasket is provided at the bottom end of the diversion hole 10. Thus, when it comes into contact with the outer surface of the eccentric disc 5, it ensures that during the process of the diversion hole 10 changing its rotational position, the shape of the elastic rubber gasket at the bottom end of the diversion hole 10 undergoes elastic deformation accordingly, and it can closely fit with the outer surface of the eccentric disc 5 to ensure the sealing performance of the closed chamber.
[0034] As Figure 4 shown, in this technical solution, a one-way valve is provided inside the diversion hole 10 and within the transmission sleeve 3. Thus, when the volume of a certain closed chamber changes from small to large, it can prevent external dust and other particulate impurities from entering into this closed chamber through the diversion hole 10 and causing blockage of the internal pipeline.
[0035] As Figure 1 、 Figure 5 shown, in this technical solution, it further includes an adjustment assembly 7 between two groups of plow blade wheels 6. The adjustment assembly 7 is provided with air bags 12 fixedly installed on the outer surface of the transmission sleeve 3. The air bags 12 are provided in three groups and are fixedly connected through a bracket 11, and a support wheel 13 is fixedly sleeved on the outer surface of the air bag 12. Thus, by adjusting the gas filling amount in the three air bags 12, the support wheel 13 can be made eccentric with respect to the transmission sleeve 3, so as to adjust the height difference between the bottom end of the outer surface of the support wheel 13 and the bottom end of the plow blade wheel 6 directly below to control the depth to which the plow blade wheel 6 sinks into the soil, and effectively improve the applicability of the device.
[0036] A method for treating heavy metal contaminated soil includes the following operating steps:
[0037] S1. Connect the repair agent delivery system connected to the diversion hole 2, and adjust the gas filling amount in the air bag 12 according to the characteristics of the soil, so as to adjust the depth to which the plow blade wheel 6 directly below sinks into the soil. Then control the traction frame to lower the connecting rod 1 and ensure that the bottom end of the support wheel 13 contacts the soil surface;
[0038] S2. Start the driving motor, and under the driving action of the belt pulley set 4, drive the transmission sleeve 3 and the plow blade wheel 6 thereon to perform a counterclockwise rotation movement. Thus, under the action of the eccentric disc 5, the volume of the closed chamber located in the upper position changes from small to large, and the volume of the closed chamber located in the lower position changes from large to small;
[0039] S21. When the volume of a certain closed chamber changes from small to large, the pressure inside it becomes smaller. Under the action of negative pressure adsorption, the repair agent in the diversion hole 2 can enter the closed chamber in the upper position through the communication hole 9;
[0040] S22. When the volume of a certain closed chamber decreases from large to small, under the extrusion of the elastic plug 8 at the corresponding position, the repair agent in the closed chamber is sprayed out through the diversion holes 10 on the plow wheel 6 below and into the soil.
[0041] S3. Then, under the traction of the traction mechanism, the device continuously moves forward. At the same time, the drive motor also drives the drive sleeve 3 and the plow wheel 6 thereon to continuously rotate counterclockwise to spray the repair agent inside the soil.
[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
