Description

Technical Field

[0001] The invention relates to the technical field of soil remediation, and in particular to an ex-situ soil gas and drug injection integrated remediation device. Background Art

[0002] Ex situ soil gas injection and chemical injection is a contaminated soil remediation technology. It is to dig the contaminated soil from the contaminated site, place it in a specific treatment unit (such as a reaction pool, treatment bed, etc.), and then inject gas and chemicals into the soil to degrade, transform or fix the pollutants in the soil, so as to achieve the purpose of soil remediation. For industrial contaminated sites, landfills and surrounding land or agricultural contaminated land, the use of ex situ soil gas injection and chemical injection technology can quickly repair severely contaminated land and achieve green and environmental protection effects.

[0003] However, factors such as soil pore structure, particle size, and aggregate state can lead to uneven gas and chemical injection. For example, when soil porosity is uneven, gas and chemical agents are more likely to flow in areas with larger pores, but difficult to penetrate in areas with smaller pores, so that pollutants in the soil cannot be treated uniformly. This unevenness may lead to over-remediation of pollutants in some areas, while pollutants in other areas remain ineffectively treated.

[0004] In the patent document with the publication number CN217694232U, a gas loosening and drug injection machine is disclosed, which includes a traveling vehicle, on which a power device, a high-pressure air pump and an injection gun are installed. The traveling vehicle is also equipped with a medicine solution tank, an intermittent mechanism and a control system, so that while injecting high-pressure gas into the deep soil layer, the medicine solution can be injected into the soil, thereby realizing the soil deep loosening and drug injection function to improve the soil environment for crop growth.

[0005] When the above device is in use, it uses an injection gun to fill the gas and chemicals into the soil, and the injection gun has a clear injection port. When the injection gun is inserted into the soil, the soil can easily enter the inside of the injection gun through the injection port, and its injection range is straight up and down, and the gas or chemical cannot be dispersed into the soil quickly, so the existing injection efficiency is poor.

[0006] Therefore, the present application proposes an ex situ soil gas injection and drug injection integrated repair device. Summary of the invention

[0012] Optionally, the area of ​​the protective limiting plate is smaller than the area of ​​the magnetic protection block, and a protective cover is provided on the outer side of the magnetic protection block.

[0013] Optionally, a plurality of groups of openings are provided on the surface of the injection plug and are staggered up and down, and the diameter of the transmission hole is larger than the diameter of the openings on the surface of the injection plug.

[0016] Optionally, the vertical guide rod is slidably installed inside the sliding cavity hollow block, and two bolt positioning rods are bolted to the connection between the vertical guide rod and the sliding cavity hollow block, and a transverse positioning rod is fixedly installed at the bottom of the vertical guide rod through a bolt positioning rod.

[0017] Optionally, two hollow rings are fixedly installed on both sides of the transverse positioning rod, and a bidirectional positioning rod is fixedly installed inside the hollow ring.

[0018] Optionally, the gap upper and lower guide assembly includes an arc-shaped guide block fixedly mounted on the bottom of the bidirectional positioning rod, a guide hollow block is fixedly mounted on the outer side of the arc-shaped guide block, a spherical guide block is rotatably mounted inside the hollow guide block, and the spherical guide block is attached to the inner wall of the arc-shaped guide block.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Whenever the transmission hole overlaps with the small hole of the injection plug, the airflow or agent flows from the small hole of the injection plug to the periphery of the soil, thereby expanding the range of agent and air delivery. Compared with the existing injection gun slowly inserted into the soil, the agent or air is delivered through the delivery holes at the same position at different heights. The hollow conduction tube can deliver the airflow or agent to various positions of the soil faster through rotation, and the gaps in the soil are different, with a larger diffusion range, so that the gas or soil can be conducted through the larger gap of the soil gap to the smaller soil gap, and the transmission hole can only be smoothly conducted when it overlaps with the small hole of the injection plug, so that the unconnected small holes of the injection plug cannot be blocked by the soil;

[0023] 2. The spherical guide block rolls in the hollow wheel block through the auxiliary connecting block. Since the auxiliary rotating rod is limited by the lateral positioning frame and can only rotate at the connection with the lateral positioning frame, the spacing of the two-way positioning rod for up and down swinging is limited, so as to avoid a large difference in depth, which will excessively affect the efficiency of inserting multiple sets of integrated transport components into the soil for repair at the same time;

[0024] 3. The second hinged rod and the third hinged rod drive the protective limit plate to fit the soil surface, and the outer side of the magnetic protection block is magnetically installed with a protective cover. Under the action of multiple protective covers, the gas is blocked when diffusing from the soil to the air and can only float toward the periphery. The staff places recovery components, such as air pumps, on the periphery to recover the polluted gas transmitted in a fixed direction, thereby improving the environmental protection efficiency and facilitating the collection of polluted gases.

[0036] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1-Figure 4 As shown, the integrated ex situ soil gas injection and drug injection repair device proposed by the present invention includes an integrated soil insertion depth adjustment component 1, and gap upper and lower guide components 2 are installed on both sides of the integrated soil insertion depth adjustment component 1, and a protective component 3 is installed at the bottom of the gap upper and lower guide components 2. An integrated transportation component 4 is installed at the bottom of the protective component 3. In order to be able to see clearly in this article, the integrated transportation component 4 is enlarged, and it itself is relatively slender, which is convenient for insertion into the soil.

[0038] Specifically, the integrated soil insertion depth adjustment component 1 includes two lateral positioning frames 101, a T-shaped positioning block 102 is fixedly installed between the two lateral positioning frames 101, a concave positioning frame 103 is fixedly installed on the top of the T-shaped positioning block 102, and sliding cavity hollow blocks 104 are fixedly installed on both sides of the concave positioning frame 103. The concave positioning frame 103 is fixedly installed at the bottom of the transmission component. The transmission component moves on the soil of a fixed site to transport the device to a specified position for gas injection and drug injection. It is explained here that the device is arranged in multiple groups about the bottom of the transportation component to facilitate the expansion of soil repair.

[0039] When two rotating wheel blocks 108 are rotatably installed on both sides of the T-shaped positioning block 102, eccentric guide rods 109 are hinged on the outer sides of the two rotating wheel blocks 108, and a positioning long rod 110 is hinged on one side of the eccentric guide rod 109. A vertical guide rod 111 is rotatably installed on the side of the positioning long rod 110 away from the rotating wheel block 108. The distance between the two eccentric guide rods 109 on both sides of the T-shaped positioning block 102 and the connection points of the T-shaped positioning block 102 at the same time is the diameter of the rotating wheel block 108, that is, when one eccentric guide rod 109 moves upward, the other eccentric guide rod 109 moves downward, thereby causing the two groups of bidirectional positioning rods 105 connected to the corresponding eccentric guide rods 109 to be able to perform up and down intermittent sliding motion.

[0040] The vertical guide rod 111 is slidably installed inside the sliding cavity hollow block 104. Two bolt positioning rods 112 are bolted to the connection between the vertical guide rod 111 and the sliding cavity hollow block 104. A transverse positioning rod 106 is fixedly installed at the bottom of the vertical guide rod 111 through a bolt positioning rod 112. Two hollow collars 107 are fixedly installed on both sides of the transverse positioning rod 106. A bidirectional positioning rod 105 is fixedly installed inside the hollow collar 107. The wheel block 108 is connected according to the drive group connected thereto. The parts rotate, and the wheel block 108 drives the positioning long rod 110 to rotate and move through the eccentric guide rod 109 during the rotation process. Since the vertical guide rod 111 can only slide along the hollow block 104 of the sliding cavity under the limitation of the bolt positioning rod 112, the vertical guide rod 111 moves up and down following the eccentric guide rod 109 through the positioning long rod 110, and the bidirectional positioning rod 105 slides up and down following the vertical guide rod 111 through the hollow collar 107 and the transverse positioning rod 106.

[0041] like Figure 1-Figure 5As shown, the gap upper and lower guide assembly 2 includes an arc-shaped guide block 201 fixedly mounted at the bottom of the bidirectional positioning rod 105, a guide hollow block 206 is fixedly mounted on the outer side of the arc-shaped guide block 201, a spherical guide block 205 is rotatably mounted inside the guide hollow block 206, and the spherical guide block 205 is attached to the inner wall of the arc-shaped guide block 201, an auxiliary connecting block 204 is fixedly mounted on the outer side of the spherical guide block 205, a hollow wheel block 202 is rotatably mounted on one side of the auxiliary connecting block 204 through a guide long rod 203, and auxiliary rotating rods 1 are fixedly mounted on both sides of the hollow wheel block 202 13, the auxiliary rotating rod 113 is fixedly installed between the two horizontal positioning frames 101, the arc guide block 201 is slidably installed on the top of the hollow integrated component 301 through the multi-hole adjustment groove 302, and the arc guide block 201 and the arc guide block 201 below are driven to move up and down through the two-way positioning rod 105. The two sets of two-way positioning rods 105 on the vertical center line of the T-shaped positioning block 102, one set moves upward, and the other set moves downward. Due to the different soil textures, the size of the gap inside is also different. When the integrated transport component 4 is inserted When the soil is soft, the existing injection guns are directly inserted into the same soil, and the inserted soil surface is the same plane. In this process, the soil between the soil is easily squeezed and compacted. Then, the air pressure and the effect of the agent fully filling the soil gaps according to the regulations in the later stage are poorer than expected. Then, one row of integrated transport components 4 is moved down first, and the other row has a depth difference with the previous row, that is, a certain depth difference is intermittently generated between each row of integrated transport components 4, thereby avoiding that the transport effect of the agent and the gas is affected. Block 205 is arc-shaped, and the spherical guide block 205 contacts the arc surface of the arc-shaped guide block 201 under the limitation of the guide hollow block 206, and then rolls along the surface of the arc-shaped guide block 201. The spherical guide block 205 rolls in the hollow wheel block 202 through the auxiliary connecting block 204. Since the auxiliary rotating rod 113 is limited by the horizontal positioning frame 101 and can only rotate at the connection with the horizontal positioning frame 101, the spacing of the up and down swinging of the two-way positioning rod 105 is limited, avoiding a large depth difference, which excessively affects the efficiency of inserting multiple sets of integrated transport components 4 into the soil for repair at the same time.

[0042] The arc-shaped guide block 201 slides along the porous adjustment groove 302 to adjust the distance between each hollow integrated component 301 and the integrated transport component 4, and adjusts the placement distance of the integrated transport component 4 according to the characteristics of the soil.

[0043] like Figure 3-Figure 8As shown, the protection component 3 includes a hollow integrated component 301, and a first hollow electric telescopic column 308 is fixedly installed at the bottom of the hollow integrated component 301. The protection component 3 also includes a first hinged rod 303 hinged on both sides of the hollow integrated component 301, and a second hinged rod 304 is hinged at the bottom of the first hinged rod 303. A magnetic protection block 306 is hinged at the middle of the second hinged rod 304, and a third hinged rod 305 is hinged on the side of the second hinged rod 304 away from the first hinged rod 303. The third hinged rod 305 is hinged on the outer side of the protection limit plate 401, and a telescopic rod 307 is fixedly installed between the magnetic protection block 306 and the protection limit plate 401. The area of ​​the protection limit plate 401 is smaller than that of the magnetic protection block 306, and a protective cover is arranged on the outer side of the magnetic protection block 306, so that multiple protective covers can be connected closely together to facilitate the recovery of gas. During the gas injection process, the flow of gas may It will carry some volatile pollutants to diffuse to the surroundings, especially for volatile organic pollutants, such as benzene series, halogenated hydrocarbons, etc. This diffusion may cause secondary pollution. The arc guide block 201 drives the hollow integrated component 301 to move toward the soil position through the two-way positioning rod 105. The first hollow electric telescopic column 308 drives the magnetic protection block 306 to move horizontally downward to the soil position through the first hinge rod 303 and the second hinge rod 304. Then the second hinge rod 304 and the third hinge rod 305 drive the protection limit plate 401 to fit the soil surface, and the outer side of the magnetic protection block 306 is magnetically installed with a protective cover. Under the action of multiple protective covers, the gas is blocked when diffusing from the soil to the air and can only float toward the periphery. The staff places recovery components, such as air pumps, on the periphery to recover the polluted gas transmitted in a fixed direction, thereby improving the environmental protection efficiency and facilitating the collection of polluted gases.

[0044] In this embodiment, Figure 1-Figure 10 As shown, the integrated transport component 4 includes a protective limit plate 401 fixedly installed at the bottom of the first hollow electric telescopic column 308, a second hollow electric telescopic rod 406 is slidably installed inside the first hollow electric telescopic column 308, a hollow conductive tube 403 is rotatably installed on one end of the second hollow electric telescopic rod 406 passing through the protective limit plate 401, and the hollow conductive tube 403 is slidably installed inside the protective limit plate 401, an injection plug 402 is fixedly installed at the bottom of the protective limit plate 401, a limit column 408 is fixedly installed on the inner wall of the injection plug 402, a threaded groove 409 is provided on the surface of the hollow conductive tube 403, the threaded groove 409 and the limit column 408 are arranged in an adaptive state, a group of transmission holes 407 are provided on the outer side of the hollow conductive tube 403, a hollow stopper 410 is fixedly installed at the bottom of the injection plug 402, and the hollow conductive tube 403 is rotatably installed inside the hollow stopper 410.

[0045] The interior of the hollow integrated component 301 is provided with an air flow conveying component 405 and a drug conveying component 404 that are in communication with the second hollow electric telescopic rod 406 and the limit column 408. When the injection plug 402 is first inserted into the soil, the second hollow electric telescopic rod 406 continues to move downward along the interior of the first hollow electric telescopic column 308. The air flow conveying component 405 or the drug conveying component 404 controls the air flow or the drug from the first hollow electric telescopic column 308 and the second hollow electric telescopic rod 406 to the hollow conductive tube 403 through the solenoid valve. The hollow conductive tube 403 contacts the limit column 408 due to the thread groove 409, causing the hollow conductive tube 403 to rotate under the guidance of the pressure of the limit column 408 through the thread groove 409, and at the same time, the hollow conductive tube 403 rotates along the hollow The inside of the block 410 rotates, and whenever the transmission hole 407 overlaps with the small hole of the injection plug 402, the airflow or medicine flows from the small hole of the injection plug 402 to the periphery of the soil, thereby expanding the range of medicine and air delivery. Compared with the existing injection gun slowly inserted into the soil, the medicine or air is delivered through the delivery holes at the same position at different heights, the hollow conduction tube 403 can deliver the airflow or medicine to various positions of the soil faster by rotating, and the gaps in the soil are different, with a larger diffusion range, so that the gas or soil can be conducted through the larger soil gap to the smaller soil gap, and the transmission hole 407 can only be smoothly conducted when it overlaps with the small hole of the injection plug 402, so that the unconnected small holes of the injection plug 402 cannot be blocked by the soil.

[0046] The surface of the injection plug 402 is provided with a plurality of groups of openings which are staggered up and down. The diameter of the transmission hole 407 is larger than the diameter of the opening on the surface of the injection plug 402. Since the opening of the injection plug 402 is smaller than the transmission hole 407, when the transmission hole 407 coincides with the small hole of the injection plug 402, it is convenient for the airflow conveying component 405 and the drug conveying component 404 to transfer the internal airflow or drug from the small hole of the injection plug 402 to the soil. Moreover, since the small holes on the surface of the injection plug 402 are staggered up and down, that is, when the hollow conduction tube 403 rotates, the airflow or drug can be transferred to various places in the soil along the small holes of the injection plug 402.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
