Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a heavy metal adsorption ball for soil improvement. Background Technology

[0002] Heavy metal pollution refers to the excessive levels of heavy metals such as copper, lead, mercury, nickel, arsenic, cadmium, and chromium in the soil, resulting in high soil concentrations and reduced soil fertility and quality. This pollution directly affects the normal growth of vegetation and causes the deterioration of the agricultural ecological environment, thus necessitating the removal of these heavy metals.

[0003] A search revealed a utility model patent with Chinese patent publication number CN219073893U, which discloses a heavy metal adsorption ball for soil improvement, relating to the field of environmental protection technology. The ball includes a plastic shell with a cap at its bottom. Several adsorption holes are formed on the bottom semicircle of the plastic shell. A reinforcing layer is provided on the inner wall of the upper semicircle inside the plastic shell. A metal barrier mesh is provided on the inner sidewall of the lower semicircle inside the plastic shell. Reinforcing protrusions are provided at the bottom of the plastic shell corresponding to the cap.

[0004] The above-mentioned device makes it easier to replace zeolite particles by designing a ball cap. However, when filling zeolite, the part of zeolite covered by the ball cap is not restricted. In order to ensure sufficient filling of zeolite particles, the area of ​​the ball cap is small, which also results in a small filling and discharge diameter. Since zeolite is a solid particle, the filling process will take a long time, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a heavy metal adsorption ball for soil improvement, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heavy metal adsorption ball for soil improvement, comprising two spherical shells, which are merged to form a complete sphere. Each of the two spherical shells is equipped with a filling assembly, which includes a holding net placed inside the spherical shell. A horizontally arranged shielding net is placed on the top of the holding net, and two equally spaced snap-fit ​​posts are provided on the outer circumference of the shielding net. A limiting groove is opened at both ends of the top outer wall of the holding net, and the two snap-fit ​​posts are slidably inserted into the two limiting grooves respectively.

[0007] Ensuring sufficient zeolite filling improves absorption efficiency and makes the filling process convenient and easy to use. Simply move the first locking post to one side until it reaches the vertical groove of the limiting slot. Then, flip the holding mesh cover so that the opening of the shielding mesh faces downwards. Since the first locking post is unrestricted, the shielding mesh and the first locking post will fall directly along the vertical groove of the limiting slot. The zeolite in the holding mesh cover will also slide out quickly. Furthermore, because the opening of the holding mesh cover is large, the zeolite can be directly scooped out using the holding mesh cover. After smoothing out any excess zeolite on top, press the shielding mesh into the limiting slot. Finally, move the first locking post into the horizontal groove of the limiting slot to complete the fixation, which facilitates subsequent merging work.

[0008] As a further preferred embodiment of this technical solution, the two spherical shells are equipped with a plurality of connecting components, and the plurality of connecting components are distributed at equal distances.

[0009] As a further preferred embodiment of this technical solution, the connecting assembly includes a limiting sleeve fixedly connected to the top of the outer circumference of a spherical shell at the bottom, and the limiting sleeve is horizontally arranged. The limiting sleeve has a receiving groove inside, and a connecting rod is fixedly connected to the bottom of the outer circumference of the spherical shell at the top. A second locking post is fixedly connected to the inner wall of one end of the connecting rod, and the second locking post is locked inside the receiving groove.

[0010] Cover the outside of the two spherical shells with your hands respectively, and then twist the top spherical shell counterclockwise. The restriction of the receiving groove is overcome, and the movable end of the limiting sleeve is lifted. Then the top spherical shell drives the second locking post to move out of the range of the limiting sleeve through the connecting rod. The two spherical shells are no longer restricted and can be easily opened. Conversely, after driving the second locking post into the inside of the limiting sleeve, it will not move easily under the restriction of the receiving groove. The disassembly and assembly process is convenient enough.

[0011] As a further preferred embodiment of this technical solution, each of the two spherical shells is provided with a hemispherical support cover on its inner circumference.

[0012] As a further preferred embodiment of this technical solution, the outer wall of the top of the bottom spherical shell is provided with an annular positioning groove, and the outer wall of the bottom of the top spherical shell is provided with a positioning ring that matches the positioning groove.

[0013] As a further preferred embodiment of this technical solution, the two spherical shells are integrally provided with a number of equally spaced connecting holes.

[0014] As a further preferred embodiment of this technical solution, the end of the limiting sleeve snap-fit ​​portion is configured as a figure-eight structure.

[0015] This invention provides a heavy metal adsorption ball for soil improvement, which has the following beneficial effects:

[0016] (1) By setting up a filling component, this utility model ensures that the zeolite is filled sufficiently, which is conducive to improving the absorption effect. The filling process is convenient and the use is more convenient. Move the first locking post to one side. When it moves to the vertical groove of the limiting groove, flip the holding net so that the opening of the shielding net faces downward. Since the first locking post is not restricted, the shielding net and the first locking post will fall directly along the vertical groove of the limiting groove. The zeolite in the holding net will also slide out quickly. Since the opening of the holding net is large, the zeolite can be directly dug out using the holding net. After smoothing out the excess zeolite on the top, press the shielding net into the limiting groove. Finally, move the first locking post to enter the horizontal groove of the limiting groove to complete the fixation, which is convenient for the subsequent merging work.

[0017] (2) By setting up a connecting component, the present invention allows two hands to cover the outside of the two spherical shells respectively, and then the top spherical shell to be rotated counterclockwise. The restriction of the receiving groove is overcome and the movable end of the limiting sleeve is lifted. Then the top spherical shell moves the second locking post out of the range of the limiting sleeve through the connecting rod. The two spherical shells are no longer restricted and can be easily opened. Conversely, after the second locking post is driven into the inside of the limiting sleeve, it will not move easily under the restriction of the receiving groove. The disassembly and assembly process is convenient enough. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4As shown, in this embodiment, a heavy metal adsorption ball for soil improvement includes two spherical shells 1, which are combined to form a complete sphere. Each of the two spherical shells 1 has a filling component 5 installed inside. The filling component 5 includes a holding net cover 501 placed inside the spherical shell 1. Both holding net covers 501 are filled with zeolite particles. A horizontally arranged shielding net 502 is placed on the top of the holding net cover 501. Two equally spaced snap-fit ​​posts 503 are provided on the outer circumference of the shielding net 502. A limiting groove 504 is opened at both ends of the top outer wall of the holding net cover 501. The two snap-fit ​​posts 503 are slidably inserted into the two limiting grooves 504 respectively.

[0025] Move the first locking post 503 to one side until it reaches the vertical groove of the limiting groove 504. Then flip the holding mesh cover 501 so that the opening of the shielding mesh 502 faces downward. Since the first locking post 503 is unrestricted, the shielding mesh 502 and the first locking post 503 will fall directly along the vertical groove of the limiting groove 504. The zeolite in the holding mesh cover 501 will also slide out quickly. Since the opening of the holding mesh cover 501 is large, the zeolite can be directly scooped out using the holding mesh cover 501. After smoothing out the excess zeolite on the top, press the shielding mesh 502 into the limiting groove 504. Finally, move the first locking post 503 into the horizontal groove of the limiting groove 504 to complete the fixation, which will facilitate the subsequent merging work.

[0026] like Figure 2 and Figure 3 As shown, several connecting components 6 are installed on the two spherical shells 1, and the connecting components 6 are distributed at equal distances.

[0027] The connecting component 6 includes a limiting sleeve 601 fixedly connected to the top of the outer circumference of a spherical shell 1 at the bottom, and the limiting sleeve 601 is horizontally arranged. The limiting sleeve 601 has a receiving groove 602 inside. A connecting rod 603 is fixedly connected to the bottom of the outer circumference of a spherical shell 1 at the top. A snap-fit ​​post 604 is fixedly connected to the inner wall of one end of the connecting rod 603. The snap-fit ​​post 604 is snapped into the receiving groove 602.

[0028] Cover the outside of the two spherical shells 1 with both hands respectively, and then twist the top spherical shell 1 counterclockwise. The restriction of the receiving groove 602 is overcome, and the movable end of the limiting sleeve 601 is lifted. Then, the top spherical shell 1 drives the second locking post 604 to move out of the range of the limiting sleeve 601 through the connecting rod 603. The two spherical shells 1 are no longer restricted and can be easily opened. Conversely, after driving the second locking post 604 into the interior of the limiting sleeve 601, it will not move easily under the restriction of the receiving groove 602. The disassembly and assembly process is convenient enough.

[0029] like Figure 2As shown, a hemispherical support cover 3 is provided on the inner circumference of each of the two spherical shells 1, which helps to improve the overall strength of the spherical shells 1 and can increase the service life of the spherical shells 1.

[0030] like Figure 2 As shown, a circumferential positioning groove 4 is provided on the top outer wall of the bottom spherical shell 1, and a positioning ring adapted to the positioning groove 4 is provided on the bottom outer wall of the top spherical shell 1. When the two spherical shells 1 are combined, the positioning ring will also be inserted into the positioning groove 4, without the need for support to align the state.

[0031] like Figure 1 and Figure 2 As shown, the two spherical shells 1 are provided with several equally spaced connecting holes 2, which allow the soil solution to enter the adsorption sphere through the connecting holes 2.

[0032] like Figure 3 As shown, the end of the locking part of the limiting sleeve 601 is set with a figure-eight structure, so that the locking post 604 can directly enter the locking sleeve 601 without manually prying open the locking part.

[0033] This invention provides a heavy metal adsorption ball for soil improvement, and its working principle is as follows:

[0034] When the device is in operation, after the adsorption spheres are buried in the soil, the zeolite inside absorbs moisture from the soil. The zeolite physically adsorbs heavy metal ions in the soil solution through van der Waals forces on its surface. Furthermore, the cations in the zeolite (such as Na+, K+, Ca2+, etc.) can exchange with heavy metal ions in the soil (such as Pb2+, Cd2+, Cr3+, etc.), thus achieving heavy metal adsorption. To replace the zeolite particles, cover the outside of the two spherical shells 1 with both hands, then twist the top spherical shell 1 counterclockwise. This overcomes the restriction of the receiving groove 602, lifting the movable end of the limiting sleeve 601. Subsequently, the top spherical shell 1, through the connecting rod 603, moves the second locking post 604 out of the limiting sleeve 601 range, and the two spherical shells 1 are no longer restricted and can be easily opened. Conversely, driving the second locking post 604... Once inside the limiting sleeve 601, it will not move easily under the restriction of the receiving groove 602, making the disassembly and assembly process convenient. Move the first snap-fit ​​post 503 to one side until it moves to the vertical groove position of the limiting groove 504. Then flip the holding mesh cover 501 so that the opening of the shielding mesh 502 faces downward. Since the first snap-fit ​​post 503 is not restricted, the shielding mesh 502 and the first snap-fit ​​post 503 will fall directly along the vertical groove of the limiting groove 504. The zeolite in the holding mesh cover 501 will also slide out quickly. Furthermore, since the opening of the holding mesh cover 501 is large, the zeolite can be directly scooped out using the holding mesh cover 501. After smoothing out the excess zeolite on the top, press the shielding mesh 502 into the limiting groove 504. Finally, move the first snap-fit ​​post 503 into the horizontal groove of the limiting groove 504 to complete the fixation, which facilitates the subsequent merging work.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
