Description

Technical Field

[0001] This invention relates to the field of soil remediation equipment technology, specifically to a microwave radiation device and an organic contaminated soil remediation system. Background Technology

[0002] In the current field of soil remediation, microwave soil remediation technology has received widespread attention due to its unique advantages, such as efficient and rapid heating and strong thermal desorption effect.

However, since the soil needs to remain in the sealed chamber for a relatively long time during the soil remediation process, the entire device needs to be very long, occupying a large area. Furthermore, since the conveyor belt needs to be stopped during the soil remediation process, it cannot operate continuously, resulting in poor processing efficiency. Summary of the Invention

[0057] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0058] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0059] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0060] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly defined.

[0061] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0063] like Figures 2-10 As shown, the present invention provides a microwave radiation device, including a frame 100, a repair unit, a lifting seat 300, a fabric trolley 400, and a drive assembly.

[0064] Multiple remediation units are arranged longitudinally at intervals. During operation, soil is sequentially added to each unit for treatment and remediation, achieving continuous soil remediation and thus improving remediation efficiency. Furthermore, the longitudinally spaced arrangement of multiple remediation units reduces the required floor space.

[0065] The lifting seat 300 is mounted on the frame 100 and is slidably connected to the frame 100 so that the lifting seat 300 can move longitudinally on the frame 100. A second guide rail 310 is provided on the top of the lifting seat 300. The second guide rail 310 is used to support the fabric carriage 400 and guide the fabric carriage 400 to ensure that the fabric carriage 400 can move in a preset direction.

[0066] The fabric trolley 400 is movably mounted on the lifting platform 300 and is used to add soil to be repaired into the target repair unit. A drive assembly is mounted on the frame 100 and is used to drive the lifting platform 300 to move up and down and to hold the lifting platform 300 in the target position. During operation, the drive assembly drives the lifting platform 300 to move up and down to the target position, thereby aligning the second guide rail 310 with the first guide rail 211 corresponding to the target repair compartment. This allows the fabric trolley 400 to move from the lifting platform 300 along the second guide rail 310 and the first guide rail 211 towards the top of the target repair compartment, and during this movement, evenly adds a layer of soil to be repaired into the target repair compartment.

[0067] like Figures 2-6 As shown, in this embodiment, the repair unit includes a repair chamber 210, a sealing assembly, an unloading assembly, and a first guide rail 211.

[0068] The remediation chamber 210 is rectangular, hollow, and open at both ends. The top opening of the chamber is the feed inlet, and the bottom opening is the discharge outlet. The remediation chamber 210 is fixedly mounted on the frame 100. Inside the chamber 210 are a microwave generator 250, an ultraviolet lamp 242, and a catalyst mesh 243 coated with catalyst. The microwave generator 250 generates microwaves to radiate heat into the soil. The ultraviolet lamp 242 generates ultraviolet light to radiate heat into the soil, air, and catalyst, thereby decomposing and adsorbing VOCs emitted from the soil. Simultaneously, the ultraviolet light reacts with the air and catalyst to produce ozone and hydroxyl radicals, further decomposing and treating the VOCs emitted from the soil.

[0069] Specifically, the power of the microwave generator 250 is controlled at 2000-6000W, and the heating time is controlled at 5-20min; the ultraviolet lamp 242 is set as an electrodeless ultraviolet lamp excited by microwave, so that the electrodeless ultraviolet lamp is excited and started by the microwave generator 250, and the ultraviolet wavelength emitted by the electrodeless ultraviolet lamp is controlled at 150-200nm, preferably 185nm.

[0070] The catalyst is a TiO2-Co3O4 supported catalyst, and the catalyst mesh 243 is a Ni mesh. Specifically, the TiO2-Co3O4 supported catalyst is obtained by coating a paste of TiO2 and Co3O4 onto a Ni mesh. The mass ratio of TiO2 to Co3O4 is 2-4:1-3. Taking advantage of the small band gap and high conduction band position of the Co3O4 semiconductor metal oxide, photogenerated electrons are more easily generated in low-frequency electromagnetic fields.

[0071] The repair chamber 210 has an air outlet on one side, which is connected to an air extraction pipe so that the gas inside the repair chamber 210 can be extracted through the air extraction pipe after the repair is completed.

[0072] A sealing assembly is installed at the inlet of the repair chamber 210. The sealing assembly has an open state and a closed state that can be switched between each other. When the sealing assembly is in the open state, the sealing assembly opens the inlet of the repair chamber 210, so that the soil to be repaired can be added into the repair chamber 210 through the inlet. When the sealing assembly is in the closed state, the sealing assembly closes the inlet of the repair chamber 210, so that the repair chamber 210 can be kept sealed.

[0073] The unloading assembly is located at the outlet of the repair chamber 210, and has an open state and a closed state that can be switched between each other. When the unloading assembly is in the open state, it opens the outlet of the repair chamber 210 so that the soil inside the repair chamber 210 can be discharged from the outlet; when the unloading assembly is in the closed state, it closes the outlet of the repair chamber 210 so that the repair chamber 210 can be kept sealed.

[0074] The first guide rail 211 is disposed on the top of the repair chamber 210 and is fixedly connected to the repair chamber 210 and / or the frame 100. The first guide rail 211 is used to provide support for the fabric carriage 400 and guide the fabric carriage 400 to ensure that the fabric carriage 400 can move in a preset direction.

[0075] like Figure 8 and Figure 9 As shown, in this embodiment, the unloading assembly includes an unloading plate 231, a first driving structure, and a guide plate 233.

[0076] The unloading plate 231 is rectangular, and its length is set along a first horizontal direction. The unloading plate 231 is rotatably connected to the repair chamber 210. Multiple unloading plates 231 are arranged at intervals along a second horizontal direction. The first and second horizontal directions are respectively the length and width directions of the repair chamber 210. That is, when the first horizontal direction is the width direction of the repair chamber 210, the second horizontal direction is the length direction; when the first horizontal direction is the length direction, the second horizontal direction is the width direction. The unloading plate 231 has an open position and a closed position that can be switched between each other. Let α be the angle between the unloading plate 231 and the horizontal plane. When the unloading plate 231 is in the open position, 45°≤α≤135°, so that the soil inside the repair chamber 210 can flow out along the unloading plate 231 from the gap between adjacent unloading plates 231 under the action of gravity. When the unloading plate 231 is in the closed position, α = 0°, so that any two adjacent unloading plates 231 remain sealed, thereby closing the discharge port of the repair chamber 210.

[0077] The first drive structure is mounted on the frame 100 or the repair chamber 210. This first drive structure drives the unloading plate 231 from the open position to the closed position or from the closed position to the open position, and can hold the unloading plate 231 in the open or unloading position. The guide plate 233 is positioned below the repair chamber 210 and is inclined so that the soil can slide downwards in the inclined direction of the guide plate 233 under the influence of gravity, thereby guiding the repaired soil to the target position.

[0078] Specifically, the first drive structure includes a first motor 232. A synchronous pulley is coaxially sleeved on the power input shaft of any unloading plate 231, and any two adjacent synchronous pulleys are connected by a synchronous belt 224. The first motor 232 is fixedly mounted on the frame 100 or the repair chamber 210, and the power output shaft of the first motor 232 is connected to the power input shaft of any unloading plate 231.

[0079] During operation, the first motor 232 drives the first drive gear to rotate, which in turn drives the first driven gear to rotate, thereby driving the unloading plate 231 to rotate. Specifically, when the first motor 232 drives the first drive gear to rotate in the forward direction, the unloading plate 231 rotates from the closed position to the open position; when the first motor 232 drives the first drive gear to rotate in the reverse direction, the unloading plate 231 rotates from the open position to the closed position. Preferably, the first motor 232 is a self-locking motor or a servo motor, so as to keep the unloading plate 231 in the open or closed position.

[0080] like Figure 7As shown, in this embodiment, the sealing assembly includes a driving roller 221, a driven roller 222, a storage roller 223, a timing belt 224, a sealing belt 225, and a second drive structure.

[0081] A drive roller 221 is disposed at the first end of the repair chamber 210 and rotatably connected to the repair chamber 210. A driven roller 222 is disposed at the second end of the repair chamber 210 and rotatably connected to the repair chamber 210. A storage roller 223 is disposed on the side of the drive roller 221 away from the driven roller 222 or on the side of the driven roller 222 away from the drive roller 221 and rotatably connected to the repair chamber 210. A timing belt 224 is sleeved on the drive roller 221 and the driven roller 222 and can rotate with the rotation of the drive roller 221 and / or the driven roller 222. Two timing belts 224 are provided, and the two timing belts 224 are respectively disposed at both ends of the drive roller 221. A sealing strip 225 is made of flexible material so that the sealing strip 225 can be wound onto the storage roller 223. The first end of the sealing strip 225 is fixedly connected to the storage roller 223, and the second end is fixedly connected to the two timing belts 224.

[0082] Specifically, the outer sidewalls of both synchronous belts 224 are fixedly inlaid with female Velcro fasteners. Correspondingly, the two sides of the sealing strip 225 are inlaid with female Velcro fasteners. The sealing strip 225 is connected to the two synchronous belts 224 via Velcro fasteners. Through the cooperation of the female and male Velcro fasteners, the sealing strip 225 is connected to the synchronous belts 224, and at the same time, the synchronous belts 224 limit the sealing strip 225, ensuring that the sealing strip 225 always remains flat.

[0083] Preferably, a guide roller 228 is also provided between the drive roller 221 and the take-up roller. Two guide rollers 228 are provided, one on the upper side and one on the lower side of the sealing strip 225, respectively. The outer peripheral wall of the guide roller 228 is provided with limiting protrusions, and the sealing strip 225 is provided with corresponding limiting grooves that match the limiting protrusions. During operation, the cooperation of the limiting protrusions and the limiting grooves ensures that the sealing strip 225 will not skew during winding and unwinding, thus ensuring that the female and male tabs of the Velcro always remain aligned.

[0084] The second drive structure is installed on the repair chamber 210 and / or the frame 100. During winding, the second drive structure drives the storage roller 223 to rotate in the forward direction to wind up the sealing strip 225, thereby opening the feed port. During release, the second drive structure drives the drive roller 221 to rotate in the reverse direction, thereby driving the synchronous belt 224 to rotate in the reverse direction. The synchronous belt 224 then drives the storage roller 223 to rotate in the reverse direction through the sealing strip 225 to release the sealing strip 225, thereby sealing the feed port.

[0085] The sealing assembly provided in this embodiment has a simple structure, and when the feed inlet of the repair chamber 210 is closed, the sealing strip 225 can be wound onto the take-up roller without occupying extra space, thereby reducing the overall height of the repair chamber 210 and thus achieving the purpose of reducing the height of the entire device.

[0086] Specifically, the second drive structure includes a second motor A226 and a second motor B227. The power output shaft of the second motor A226 is connected to the power input shaft of the drive roller 221, and the power output shaft of the second motor B227 is connected to the power input shaft of the storage roller 223. Both the second motor A226 and the second motor B227 are non-self-locking motors, meaning that even when power to the second motors A226 and B227 is off, their power output shafts can still be driven to rotate by applying torque to them.

[0087] like Figures 2-4 As shown, in this embodiment, the drive assembly includes a lead screw 510, a nut 520, and a fourth motor 530.

[0088] The lead screw 510 is longitudinally oriented and rotatably connected to the frame 100. A nut 520 is fitted onto the lead screw 510, and rotating the nut 520 drives it to move along the axis of the lead screw 510. The nut 520 is fixedly connected to the lifting seat 300, allowing the lifting seat 300 to move along with the nut 520. A fourth motor 530 is fixedly mounted on the frame 100, and its power output shaft is connected to the lead screw 510 to drive its rotation. Specifically, the power output shaft of the fourth motor 530 is connected to the lead screw 510 via a coupling, gear structure, and synchronous belt 224, which will not be elaborated further here. The fourth motor 530 is either a servo motor or a self-locking motor, designed to maintain the lifting seat 300 in the target position.

[0089] During operation, the fourth motor 530 drives the lead screw 510 to rotate, which in turn drives the lifting seat 300 to move via the nut 520. Specifically, when the fourth motor 530 drives the lead screw 510 to rotate in the forward direction, the lifting seat 300 is driven to rise via the nut 520; when the fourth motor 530 drives the lead screw 510 to rotate in the reverse direction, the lifting seat 300 is driven to fall via the nut 520. Therefore, by driving the lead screw 510 to rotate in either the forward or reverse direction, the purpose of driving the lifting seat 300 to move up and down can be achieved, resulting in a simple structure.

[0090] like Figure 6 and Figure 10 As shown, in this embodiment, the repair unit also includes a mounting bracket 241 and a third drive structure.

[0091] The inner wall of the repair chamber 210 is provided with a receiving groove, and a mounting frame 241 is provided in the receiving groove. The ultraviolet lamp tube 242 and the catalyst mesh 243 are mounted on the mounting frame 241. The first end of the mounting frame 241 is hinged to the repair chamber 210, and the second end can swing back and forth between a first position and a second position. When the mounting frame 241 is in the first position, the mounting frame 241 is hidden in the receiving groove; when the mounting frame 241 is in the second position, the mounting frame 241 is located outside the receiving groove.

[0092] The third drive structure is provided on the repair chamber 210. The third drive structure is used to drive the mounting bracket 241 to move from the first position to the second position or from the second position to the first position, and can hold the mounting bracket 241 in the first position and the second position.

[0093] During operation, as the soil is added to the remediation chamber 210 by the material carrier, the third drive structure drives the mounting frame 241 to the first position. This allows the catalyst mesh 243 and ultraviolet lamp 242 mounted on the mounting frame 241 to be concealed within the receiving tank, thus preventing damage to the catalyst mesh 243 and ultraviolet lamp 242 from falling soil. After the soil is added, the third drive structure drives the mounting frame 241 to the second position, placing the catalyst mesh 243 and ultraviolet lamp 242 outside the receiving tank, thereby enabling the ultraviolet lamp 242 to provide comprehensive irradiation to the soil within the remediation chamber 210.

[0094] Specifically, the third drive structure includes a third motor 244. The power output shaft of the third motor 244 is connected to the power input shaft of the mounting bracket 241. Specifically, the power output shaft of the third motor 244 and the power input shaft of the mounting bracket 241 are connected via a coupling, gear structure, synchronous belt 224, etc., which will not be elaborated further here. The third motor 244 is a servo motor, self-locking motor, etc., to maintain the mounting bracket 241 in the first and second positions.

[0095] Preferably, the microwave generator 250 is embedded in the side wall of the receiving groove.

[0096] The present invention also provides an organic contaminated soil remediation system, including the microwave radiation device described in any of the above embodiments.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
