Soil heavy metal adsorbent mixing and dispersing device

Abstract

This utility model provides a soil heavy metal adsorbent mixing and dispersion device, relating to the field of soil heavy metal adsorbent mixing technology. It includes a mounting base, with a rotating frame rotatably connected to one side of the mounting base. Several rotating joints are installed through the surface of the rotating frame. The water inlet end of each rotating joint is fixedly connected to the surface of the rotating frame, and a spiral stirring blade is fixedly installed at the water outlet end of the rotating joint. By setting the spiral stirring blade, the rotating frame's rotation allows the spiral stirring blade to insert into the soil, and the rotation of the spiral stirring blade agitates the soil. During this agitation, the heavy metal adsorbent enters the hollow spiral stirring blade along the rotating joint and is ultimately evenly dispersed in the soil through the permeable holes on its surface, ensuring uniform dispersion of the heavy metal adsorbent.

Description

Technical Field

[0001] This utility model relates to the field of soil heavy metal adsorbent mixing technology, and in particular to a soil heavy metal adsorbent mixing and dispersing device. Background Technology

[0002] Soil heavy metal adsorbents are materials used to remediate soil contaminated with heavy metals. They can reduce the migration and bioavailability of heavy metals in the soil through adsorption, precipitation, and complexation. To ensure the quality of soil heavy metal adsorbents, it is necessary to ensure that they are mixed evenly.

[0003] Therefore, a handheld farmland remediation device for applying soil heavy metal adsorbents, disclosed in CN220591111U, is described. Power is supplied to the rotation of the tilling roller via a power mechanism, and the operator pushes the device by holding the handle. The tilling roller first rotary tills the land to be remediated, ensuring soil loosening (at this time, the nozzle is closed). After the soil loosens, the nozzle is turned on to apply the solidifying agent to the tilled land, and the amount of solidifying agent applied is adjusted in a timely manner through flow and speed regulating valves. Simultaneously, the rotating blades of the rotary tiller fully integrate the applied solidifying agent with the soil, achieving the purpose of this invention. The integrated land is left to stand for one week before sowing.

[0004] However, if the solidifying agent is sprayed onto the soil surface first and then the soil is turned over, the solidifying agent will be absorbed by the surface soil. Even if the solidifying agent penetrates from the surface soil into the deeper soil during subsequent turning, it takes a long time for the solidifying agent to slowly penetrate from the surface soil to the deeper soil. This will significantly prolong the remediation cycle. For example, if it is necessary to remediate heavy metal pollution in the deep soil, it may take several days or even weeks to complete the penetration, which is inefficient in practical applications.

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a soil heavy metal adsorbent mixing and dispersion device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a soil heavy metal adsorbent mixing and dispersing device, comprising a mounting base, a rotating frame rotatably connected to one side of the mounting base, a plurality of rotating joints being installed through the surface of the rotating frame, the water inlet end of the rotating joint being fixedly connected through the surface of the rotating frame, and a spiral stirring blade being fixedly installed at the water outlet end of the rotating joint, the spiral stirring blade being hollow inside and communicating with the water outlet end of the rotating joint, a plurality of water-permeable holes being opened on the surface of the spiral stirring blade, a water inlet pipe being fixedly installed on the rotating frame spanning the water inlets of the plurality of rotating joints, a solenoid valve being provided between the water inlet pipe and each water inlet end of the rotating joint, a reagent tank and a water pump being fixedly installed on the upper surface of the mounting base, the water inlet and outlet ends of the water pump being connected to the reagent tank and the water inlet of the water inlet pipe, respectively.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a soil heavy metal adsorbent mixing and dispersing device includes a mounting base 1, which is connected to a mobile device (such as a rotary tiller, tractor, or other vehicle). The mobile device drives the mounting base 1 to move along the soil surface where the heavy metal adsorbent needs to be mixed. A rotating frame 4 is rotatably connected to one side of the mounting base 1. Several rotating joints 18 are installed through the surface of the rotating frame 4. The water inlet end of the rotating joint 18 is fixedly connected through the surface of the rotating frame 4, and a spiral stirring blade 5 is fixedly installed at the water outlet end of the rotating joint 18. The spiral stirring blade 5 is hollow inside and communicates with the water outlet end of the rotating joint 18. Several water permeable holes 19 are opened on the surface of the spiral stirring blade 5. Soil is prevented from entering the spiral stirring blade 5 by setting a filter screen in the water permeable holes 19. In actual operation, the rotating frame 4 rotates until the spiral stirring blade 5 is inserted into the soil. As the mounting base 1 moves, the spiral mixing blade 5 moves during its rotation, thus turning over the soil. During this process, the heavy metal adsorbent enters the hollow spiral mixing blade 5 along the rotary joint 18 and is then evenly dispersed in the soil through the permeable holes 19 on its surface. A water inlet pipe 6 spanning several rotary joints 18 is fixedly installed on the rotating frame 4. A solenoid valve 7 is installed between the water inlet pipe 6 and each rotary joint 18 water inlet. A reagent tank 2 and a water pump 3 are fixedly installed on the upper surface of the mounting base 1. The inlet and outlet of the water pump 3 are connected to the inlet of the reagent tank 2 and the water inlet of the water inlet pipe 6, respectively. The outlet of the water pump 3 is connected to the water inlet pipe 6 through a flexible hose, which does not affect the rotation of the rotating frame 4. In actual use, the water pump 3 is used to transport the heavy metal adsorbent stored in the reagent tank 2 to the water inlet pipe 6.

[0024] A worm gear ring 14 is fixedly installed on the outer side of the water outlet end of the rotary joint 18. A worm 15 that meshes with several worm gear rings 14 is rotatably connected to the bottom surface of the rotating frame 4. In this scheme, the worm 15 is driven to rotate by installing a stepper motor on the rotating frame 4, so that the corresponding meshing worm gear rings 14 can drive the water outlet end of the rotary joint 18 and the corresponding fixed spiral stirring blades 5 to rotate, thereby agitating the soil.

[0025] A rod 10 is fixedly installed on the rotating frame 4, parallel to the water inlet pipe 6 and passing through the side of the mounting base 1. Two toothed rings 16 are keyed to the rod 10. The two toothed rings 16 are rotatably installed on both sides of the mounting base 1. Two racks 17 are inserted into the bottom surface of the mounting base 1. The two racks 17 are meshed with the two toothed rings 16 respectively, and the other ends of the two racks 17 are integrally formed. An electric telescopic rod 11 is provided between the racks 17 and the bottom surface of the mounting base 1. By using the electric telescopic rod 11 to extend and retract to drive the racks 17 to move, the meshing toothed rings 16 can rotate relative to the mounting base 1. In the case of key connection, the rod 10 and the rotating frame 4 are rotated. In addition, in this solution, the rod 10 is keyed by setting a keyway, and the toothed rings 16 are keyed by setting a key block that slides through the keyway. This ensures that the rod 10 can rotate with the toothed rings 16 while sliding relative to the toothed rings 16.

[0026] One end of the inlet pipe 6 extends outward through the rotating frame 4 and is connected to the outlet of the water pump 3 on the mounting base 1 by a three-way valve 13. Two ports of the three-way valve 13 have built-in valves. One port of the built-in valve on the three-way valve 13 connects to the outlet of the water pump 3, while the other port connects to the outside. An electric telescopic rod 11 is also fixedly installed on the side of the mounting base 1, and a collection box 12 is fixedly installed at the telescopic end of the electric telescopic rod 11. The collection box 12 is used to connect to the other port of the built-in valve of the water pump 3. Figure 1 As shown, the two valve ports of the three-way valve 13 are located on the left and the top, respectively. Therefore, in actual use, the top valve port is closed and the left valve port is open, so that the water pump 3 can deliver water into the inlet pipe 6. When the left valve port is closed and the top valve port is open, the remaining heavy metal adsorbent in the spiral stirring blade 5 can flow back along the rotary joint 18 and the inlet pipe 6 after the rotating frame 4 is rotated 180 degrees upward to the inverted state, and finally flow out along the valve port in the middle position of the three-way valve 13. By using the electric telescopic rod 11 in this scheme to extend, the collection box 12 can be moved to the position directly below the valve port in the middle position of the inverted three-way valve 13, so that the remaining heavy metal adsorbent flowing out from the middle valve port can be collected.

[0027] An electric push rod 8 is fixedly installed on the mounting base 1, which is parallel to the insertion rod 10. A rotating ring 9, which is coaxial with the insertion rod 10 and rotatably connected to the rotating frame 4, is fixedly installed at the telescopic end of the electric push rod 8. During the process of the spiral mixing blade 5 rotating and turning the soil, the extension and retraction of the electric push rod 8 in this scheme is used to make the rotating ring 9 pull the rotating frame 4 and the internal insertion rod 10 move relative to the toothed ring 16, so as to realize the lateral swing of the spiral mixing blade 5 and ensure the effect of soil turning.

[0028] Working principle: After fixing the position of the mounting base 1, the drive gear ring 16 rotates, causing the insertion rod 10 to drive the rotating frame 4 to rotate to the desired position. Figure 1As shown in the orientation state, during the downward swing of the rotating frame 4, the spiral stirring blade 5 will insert into the soil and use the rotation of the spiral stirring blade 5 to turn the soil. During the turning of the soil, the water pump 3 will transport the heavy metal adsorbent stored in the agent tank 2 to the water inlet pipe 6, and then enter the corresponding rotary joint 18 and spiral stirring blade 5 through the opened solenoid valve 7, and finally be evenly dispersed in the soil through the permeable holes 19 set on the surface.

[0029] The wiring diagrams for the water pump 3, motor, solenoid valve 7, electric push rod 8, electric telescopic rod 11, and three-way valve 13 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the water pump 3, motor, solenoid valve 7, electric push rod 8, electric telescopic rod 11, and three-way valve 13 will not be explained in detail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
