Description

Technical Field

[0001] This application relates to the technical field of contaminated soil remediation equipment, specifically a soil leaching remediation device. Background Technology

[0002] Soil leaching remediation equipment is a technology that uses water or chemical solvents to transfer pollutants (such as heavy metals and organic matter) in soil from the solid phase to the liquid phase. Its core principle is to use reagents (such as inorganic acids, alkalis, salts, and chelating agents) to react with heavy metals in the soil to form soluble heavy metal ions or complexes, which then flow out with water or chemical solvents, thereby achieving the purpose of purifying and remediating the soil.

[0003] For example, patent CN218611009U discloses a soil washing device. This patent achieves automatic discharge through the conveying action of a conveyor belt. When the soil is relatively fine and does not need to be crushed, it is added from one end of the conveyor belt for conveying. The washing pipe is connected to the external washing liquid conveying pipe through the pipe head. Inorganic acid is sprayed out through multiple sets of washing nozzles for comprehensive washing. The washed soil is conveyed into the discharge protective cover and finally unloaded and collected. When the soil is in clumps, the clumps are added into the feeding cylinder from the conical feeding hopper. Due to the servo motor driving the crushing blades to rotate quickly, the soil is quickly crushed and finally falls onto the conveyor belt for comprehensive washing.

[0004] In the implementation of the above-mentioned patent, although the soil is crushed, the soil tends to pile up because it is sprayed and washed on a conveyor belt. The soil at the top is easier to wash, while the soil at the bottom is less likely to come into contact with the washing liquid, resulting in uneven local washing of the soil and affecting the treatment effect. Therefore, it is necessary to provide a soil washing and remediation device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a soil rinsing and remediation device that achieves the effect of allowing the soil to be treated to come into uniform contact with the rinsing solution.

[0007] The technical solution adopted by this application to solve its technical problem is: a soil leaching remediation device, including a support base with a cover installed at the upper end of the support base; a flow channel space disposed inside the cover for soil conveying; a feed hopper disposed on the cover and communicating with the flow channel space; a rotating shaft adapted for rotation located inside the flow channel space; a spiral blade mounted on the rotating shaft; at least one set of spraying mechanisms disposed on the soil conveying path, the spraying mechanism including: a liquid pump mounted on the cover; a bracket mounted on the inner top of the cover, a spray pipe mounted on the bracket, the spray pipe communicating with the output end pipe of the liquid pump, and multiple sets of nozzles disposed on the spray pipe; a connecting ring disposed in the flow channel space, the connecting ring having through holes matching the flow channel space inside; and multiple sets of leakage holes communicating with the through holes on the connecting ring, the leakage holes matching the nozzles.

[0008] Furthermore, the flow channel space is divided into a first section close to the feed hopper and a second section away from the feed hopper, with the connecting ring connecting the first and second sections.

[0009] Furthermore, the through hole includes a bottom arc at the bottom and a top arc at the top, both of which are semi-circular arcs. The diameter of the bottom arc is the same as the diameter of the flow channel space, and the diameter of the top arc is larger than the diameter of the flow channel space.

[0010] Furthermore, multiple sets of drainage holes are provided at the bottom of the flow channel space, and a wastewater tank is placed at the lower end of the support base.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figures 1-2 As shown, this application provides a soil leaching remediation device, including a conveying mechanism 1. The conveying mechanism 1 is mainly used for conveying soil to be remediated. The conveying mechanism 1 includes a support base 11, and a cover 12 is fixedly installed on the upper end of the support base 11. The interior of the cover 12 is hollow, and a front plate 19 and a rear plate 110 are fixedly installed at both ends of the cover 12, thereby forming a space for soil conveying through the front plate 19, the rear plate 110 and the cover 12.

[0030] Meanwhile, a feed hopper 16 is provided on the top of the cover 12, which is used for introducing soil;

[0031] like Figures 2-3 As shown, an upper cover 17 is fixedly installed at the upper end of the inside of the cover 12, between the front plate 19 and the rear plate 110. At the same time, a lower cover 18 is fixedly installed at the lower end of the inside of the cover 12, also between the front plate 19 and the rear plate 110. An upper shell 171 is provided at the lower end of the upper cover 17, and a lower shell (not shown in the figure) is provided at the upper end of the lower cover 18. A flow channel space for soil transportation is formed between the upper shell 171 and the lower shell.

[0032] It should be noted that a window (not shown in the figure) is provided at the upper end of the upper shell 171. The feed hopper 16 is adapted to extend into the cover 12 and communicate with the window, so that the soil introduced from the feed hopper 16 can directly enter the flow channel space.

[0033] Continue to refer to Figures 2-3 A rotating shaft 111 is rotatably mounted between the front plate 19 and the rear plate 110. At the same time, a motor 13 is fixedly mounted on the support base 11. A coupling 14 is fixedly mounted on the output end of the motor 13. The coupling 14 is connected to one end of the rotating shaft 111, so that the rotating shaft 111 is suitable for rotation under the drive of the motor 13.

[0034] Meanwhile, a spiral blade 112 is fixedly installed on the rotating shaft 111 along the length direction. The spiral blade 112 is located in the flow channel space, so that the spiral blade 112 is suitable for rotating synchronously with the rotating shaft 111. As the spiral blade 112 rotates, the soil can be transported away from the feed hopper 16. During the soil transport process, the soil can rotate synchronously with the spiral blade 112, thereby achieving the purpose of tumbling the soil.

[0035] Furthermore, during the soil transport process, the soil can be compacted by the squeezing and transporting of the spiral blades 112 and the upper shell 171 (lower shell), thereby breaking up large pieces of soil and reducing the particle size of the soil.

[0036] It should be noted that a through discharge hole (not shown in the figure) is provided on the rear plate 110. The discharge hole is adapted to the size of the flow channel space, so that the soil conveyed by the spiral blade 112 can be discharged through the discharge port.

[0037] like Figures 2-4 As shown, at least one set of spraying mechanisms 3 is installed along the soil transport path. These spraying mechanisms 3 are used to spray agents onto the soil to remove pollutants such as heavy metals from the soil. Specifically:

[0038] The spraying mechanism 3 includes a liquid pump 31 fixedly installed on the housing 12. The input end of the liquid pump 31 is connected to the medicine tank pipeline, so that the liquid medicine in the medicine tank can be pumped out through the liquid pump 31.

[0039] Meanwhile, a bracket 33 is fixedly installed at the top inside the cover 12. A spray pipe 34 is installed on the bracket 33. A liquid pipe 32 is connected between the spray pipe 34 and the output end of the liquid pump 31, so that the liquid medicine pumped out by the liquid pump 31 will be introduced into the liquid pipe 32.

[0040] Continue to refer to Figure 4 At least one set of connecting rings 36 are provided between the upper shell 171 and the lower shell. It can be understood that the flow channel space between the upper shell 171 and the lower shell is discontinuous and divided into at least two sets. For ease of explanation, the flow channel space between the upper shell 171 and the lower shell is divided into a first section close to the feed hopper 16 and a second section away from the feed hopper 16. The connecting rings 36 connect the first section and the second section, so that the connecting rings 36 complete the flow channel space to facilitate the continuous flow of soil.

[0041] like Figure 4As shown, a through hole (not shown in the figure) matching the flow channel space is provided inside the connecting ring 36. At the same time, multiple sets of nozzles 35 are provided on the liquid pipe 32, and multiple sets of leakage holes (not shown in the figure) communicating with the through hole are provided on the top of the connecting ring 36. The leakage hole matches the nozzle 35, so that the liquid introduced into the liquid pipe 32 will enter the through hole through the nozzle 35 and be sprayed into the soil of the through hole to facilitate the combination with heavy metals in the soil.

[0042] The through hole includes a bottom arc 361 at the bottom and a top arc 362 at the top. Both the bottom arc 361 and the top arc 362 are semi-circular arcs. The diameter of the bottom arc 361 is the same as the diameter of the flow channel space, while the diameter of the top arc 362 is larger than the diameter of the flow channel space. Soil can be transported through the cooperation of the spiral blade 112 and the bottom arc 361 when passing through the through hole, while the top arc 362 does not contact the spiral blade 112. Therefore, most of the soil will not reach the top arc 362, and the leakage hole will not be blocked by soil.

[0043] Of course, the soil can also be transported by the thrust of the subsequent soil, so the soil will not remain in the through hole and cause blockage of the subsequent soil;

[0044] like Figures 1-3 As shown, multiple sets of drainage holes (not shown in the figure) are provided at the bottom of the lower shell of the lower cover 18. The multiple sets of drainage holes are evenly arranged along the direction of soil transportation. At the same time, a wastewater tank 15 is placed at the lower end of the support base 11. Thus, during the soil transportation process, the wastewater that reacts with heavy metals will enter the wastewater tank 15 through the drainage holes, thereby realizing soil remediation.

[0045] In order to collect the remediated soil, such as Figures 2-3 and Figure 5 As shown, a discharge mechanism 2 is provided on the support base 11. The discharge mechanism 2 is used to compact the soil for easy collection. The discharge mechanism 2 includes a tail plate 21 fixedly installed on the support base 11 near the rear plate 110. At the same time, a bearing seat 113 is fixedly installed on the support base 11 on the outside of the tail plate 21. The bearing seat 113 is used to install the tail of the rotating shaft 111. It can be understood that the rotating shaft 111 passes through the rear plate 110 and the tail plate 21 and is installed with the bearing seat 113, thereby restricting the tail of the rotating shaft 111 and maintaining the stability of the rotating shaft 111.

[0046] Meanwhile, a cylinder 22 is fixedly installed on the tail plate 21. The output end of the cylinder 22 is set towards the rear plate 110, and a pressure plate 23 is fixedly installed on the output end of the cylinder 22. The pressure plate 23 is suitable for cooperating with the rear plate 110 to compact the soil.

[0047] Meanwhile, a material box 114 is installed at the bottom of the discharge hole to facilitate soil collection;

[0048] In summary, when soil needs to be collected, the soil is introduced into the flow channel space through the feed hopper 16. As the spiral blades 112 rotate, the introduced soil gradually moves towards the discharge hole. During the movement, the soil is washed by the spray mechanism 3, and the wastewater that reacts with heavy metals will enter the wastewater tank 15 through the leakage hole.

[0049] The soil then continues to move toward the discharge hole. When a large amount of soil reaches the discharge hole, the pressure plate 23 moves toward the rear plate 110 under the action of the cylinder 22 to squeeze and compact the soil.

[0050] As the pressure plate 23 retracts, the compacted soil falls into the material bin 114 under the action of gravity, thus facilitating the collection and transportation of the soil.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
