Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, and specifically relates to a farmland soil remediation device based on ultraviolet catalysis. Background Technology

[0002] With rapid industrial development, farmland soil pollution has become increasingly serious. Soil pollutants are mainly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, salts, heavy metals, and radioactive elements, while organic pollutants mainly include organic pesticides, phenols, and wastewater. When the amount of harmful substances in the soil exceeds its self-purification capacity, artificial remediation is required to restore the polluted soil to its normal function. Currently, commonly used soil remediation technologies can be broadly classified into three categories: physical remediation, chemical remediation, and bioremediation. However, bioremediation has high environmental requirements and a long treatment cycle, making it unsuitable for on-site remediation of farmland soil. Although chemical remediation has a short treatment cycle, it can cause secondary pollution to the soil, affecting its subsequent normal use. Existing physical remediation technologies use equipment that occupies a large space and is not easily moved, making them unsuitable for on-site remediation of farmland soil. Furthermore, the high cost of remediation prevents its widespread adoption.

[0003] Therefore, it is necessary to design a farmland soil remediation device that can at least solve some of the above problems and defects. Summary of the Invention

[0004] To address the above-mentioned technical problems, this invention proposes a farmland soil remediation device based on ultraviolet catalysis. The device has a simple, practical, and convenient structure, is easy to move and transport, and is suitable for on-site soil remediation in farmland. It improves soil remediation efficiency and avoids secondary pollution of the soil during the remediation process.

[0005] The technical solution of this utility model is: This utility model proposes a farmland soil remediation device based on ultraviolet catalysis, including an inner cylinder with a top opening, a detachable top cover covering the top opening, and a pallet that can be raised and lowered and is movably disposed inside the inner cylinder. The bottom of the top cover is provided with a number of ultraviolet lamp beads facing the tray. The side wall and bottom wall of the tray are provided with a number of drainage holes arranged at intervals. The tray is provided with a number of lifting ropes that are detachably connected to it and are evenly spaced along the circumference. The other end of the lifting ropes passes around the top of the side wall of the inner cylinder and extends outward.

[0006] Preferably, the top of the inner cylinder sidewall is provided with a plurality of limiting grooves evenly spaced along the circumferential direction, and the lifting cable is slidably embedded in the limiting grooves.

[0007] Preferably, the outer wall of the inner cylinder is further provided with a plurality of guide strips evenly spaced along the circumferential direction, and the guide strips are located directly below the limiting groove; The guide bar is provided with a longitudinal through groove adapted to the lifting cable, and the lifting cable is movably inserted into the longitudinal through groove.

[0008] Preferably, the side wall of the tray is provided with a plurality of lifting holes evenly spaced along the circumference, and the end of the lifting rope is provided with a lifting hook fixedly connected thereto, the lifting hook being detachably inserted into the lifting hole.

[0009] Preferably, the farmland soil remediation device based on ultraviolet catalysis provided by this utility model further includes a detachable outer cylinder sleeved around the outer periphery of the inner cylinder. The outer cylinder is provided with a lift handle that can be raised and lowered and embedded in its side wall. The lift handle is fixedly connected to the other end of the lifting cable.

[0010] Preferably, the outer cylinder sidewall is provided with at least one guide groove, and the lifting handle is movably inserted into the guide groove; The guide groove includes a longitudinal section and a locking section that are connected to each other. The longitudinal section is parallel to the central axis of the outer cylinder, and the locking section is located at the bottom end of the longitudinal section and is in the shape of a "G".

[0011] Preferably, the lifting handle includes a locking part movably disposed between the inner wall of the outer cylinder and the outer wall of the inner cylinder, a connecting part movably disposed in the guide groove, and a handle part disposed on the outside of the outer cylinder.

[0012] This utility model has the following advantages and effects compared with the prior art: (1) The top cover with several ultraviolet lamp beads at the bottom can emit ultraviolet light to the soil to be remediated placed in the tray, thereby promoting the catalytic decomposition of pollutants such as organic matter in the contaminated soil to complete the soil remediation, improving the efficiency of soil remediation, and avoiding secondary pollution of the soil during the soil remediation process. (2) A liftable tray is used inside the inner cylinder. The soil to be repaired can be mixed with the catalyst and placed in the tray for ultraviolet irradiation catalytic digestion reaction. The liftable tray facilitates the placement and removal of soil. There is no need to reach into the inner cylinder to dig out the soil or overturn and dump the soil from the inner cylinder as a whole, which improves the convenience of operation. (3) Several lifting ropes are evenly spaced along the circumference, and the other end of the lifting ropes goes around the top of the inner cylinder side wall and extends outward. The operator can pull the extended end of the lifting rope to raise or lower the pallet without having to reach into the inner cylinder.

Specifically, the top cover 2 is provided with a control circuit (not shown in the figure) connected to the ultraviolet lamp beads 21 to realize the circuit control of the ultraviolet lamp beads 21 emitting light. Since it is a mature existing technology in this field, its specific structure and principle will not be shown or described here.

[0018] Combination Figure 2 and Figure 3 As shown, the side wall and bottom wall of the tray 3 are provided with several drainage holes 31 arranged at intervals. The tray 3 is provided with four lifting cables 4 that can be detachably connected to it. The four lifting cables 4 are evenly distributed in the circumferential direction with the axis of the inner cylinder 1 as the center. One end of the lifting cable 4 is detachably connected to the tray 3, and the other end passes around the top of the side wall of the inner cylinder 1 and extends outward, so that the tray 3 can be raised and lowered by pulling the extended end of the lifting cable 4.

[0019] For details, please refer to Figure 2 and Figure 3 As shown, four lifting holes 32 are evenly spaced along the circumference near the top of the side wall of the tray 3. The end of the lifting rope 4 is provided with a lifting hook 41 fixedly connected to it. The lifting hook 41 is detachably inserted into the lifting hole 32.

[0020] Combination Figure 2 and Figure 4 As shown, the top of the side wall of the inner cylinder 1 is provided with four evenly spaced limiting grooves 11 along the circumferential direction. The limiting grooves 11 are adapted to the lifting rope 4 and the lifting rope 4 is slidably embedded in the limiting grooves 11. The outer wall of the inner cylinder 1 is also provided with four evenly spaced guide bars 12 along the circumferential direction. The guide bars 12 are located directly below the limiting grooves 11. The guide bars 12 are provided with longitudinal through grooves 121 adapted to the lifting rope 4, and the lifting rope 4 is movably inserted into the longitudinal through grooves 121 of the guide bars 12. The longitudinal through grooves 121 are arranged parallel to the central axis of the inner cylinder 1.

[0021] like Figure 1 and Figure 2As shown, the outer cylinder 5 is provided with a lift handle 51 that is movable and height-adjustable and embedded in its side wall. The lift handle 51 is fixedly connected to the other end (extended end) of the lifting cable 4, so that the lifting cable 4 can be moved by pulling the lift handle 51, thereby realizing the lifting and lowering movement of the tray 3. Specifically, the side wall of the outer cylinder 5 is provided with four guide grooves 52 that are evenly spaced along the circumferential direction. The lift handle 51 is movably inserted into the guide groove 52. The guide groove 52 includes a longitudinal part 521 and a locking part 522 that are connected.

[0022] In practical use, the soil to be repaired (mixed with catalyst) is placed in the tray 3, and then the top cover 2 is placed on the top opening of the inner cylinder 1. The ultraviolet lamp 21 is controlled by the control circuit inside the top cover 2 to emit ultraviolet light to irradiate the soil to be repaired, so as to promote the chemical reaction to catalyze the decomposition of organic matter and other pollutants in the soil. After the set time of irradiation is completed, the top cover 2 is opened, and the handle 513 of the lifting handle 51 is pressed down along the longitudinal part 521 of the guide groove 52, so that the tray 3 is lifted up by the lifting rope 4. When the lifting handle 51 is pressed down and moved to the end of the longitudinal part 521 of the guide groove 52, the lifting handle 51 is moved along the shape of the locking part 522 of the guide groove 52, so that the lifting handle 51 is locked and fixed at the end of the locking part 522. Finally, the repaired soil in the tray 3 can be separated and taken out. The above steps can be repeated for the next soil repair.

[0023] Optionally, in some embodiments, the locking part 511, the connecting part 512, and the handle part 513 are connected in an integral structure, and the extended end of the lifting cable 4 is fixedly connected to the locking part 511 or the connecting part 512.
