Description

Technical Field

[0001] This utility model relates to the field of soil remediation equipment technology, and in particular to a soil remediation device. Background Technology

[0002] Soil is composed of various particulate minerals, organic matter, water, air, microorganisms, etc., and can support plant growth. However, soil can become polluted after long-term use. There are many causes of soil pollution, such as industrial sludge, agricultural waste, sewage irrigation, atmospheric pollutant deposition, and the excessive use of mineral fertilizers and pesticides containing heavy metals. Soil remediation is necessary, which is a technical measure to restore polluted soil to its normal function. Generally, soil remediation agents are mixed with the polluted soil to remove harmful substances. Therefore, environmental protection-grade contaminated soil remediation equipment is required to meet the needs of soil remediation.

[0003] Chinese Patent 202420945148.1 discloses a soil remediation device for environmental protection, relating to the field of soil remediation devices for environmental protection. The device includes a remediation chamber with a feeding cavity. A first sieve plate, a second sieve plate, and a third sieve plate are fixedly installed inside the remediation chamber. This invention uses a pulverizing mechanism in the feeding cavity, the first cavity, and the second cavity to repeatedly pulverize the soil, making it less prone to clumping. During the pulverization process, a chemical solution is sprayed onto the soil through a ring pipe, allowing the soil and chemical solution to mix more thoroughly and increasing the soil remediation effect.

[0004] In soil remediation, the device uses an electric motor as a power source. The motor drives the rotating shaft to rotate, and the blades on the shaft tumble as it rotates, causing violent collisions with the soil to achieve soil pulverization. However, while the electric motor drives the rotating shaft and pulverizing blades to pulverize the soil, the pulverization effect is poor and it takes a long time. In addition, the pulverizing blades can easily throw the soil above the remediation box out when rotating. Therefore, a soil remediation device is proposed to solve the above problems.

[0029] like Figure 1-4 As shown, the soil remediation device proposed in this utility model includes a first crushing shell 8 and a second crushing shell 11. The discharge port at the bottom of the first crushing shell 8 is connected to the first connecting shell 10 through a second connecting shell 14. The first connecting shell 10 is connected to the feed port at the top of the second crushing shell 11. The feed port at the top of the first crushing shell 8 is connected to the feed hopper 7.

[0030] The first crushing shell 8 is provided with a first crushing component inside, and the second crushing shell 11 is provided with a second crushing component inside;

[0031] It includes an inlet pipe 9 and a medicine spray nozzle 15. Multiple medicine spray nozzles 15 are equidistantly distributed on the inner end face of the second connecting housing 14. The inlet pipe 9 is located outside the second connecting housing 14 and is connected to the multiple medicine spray nozzles 15.

[0032] The second crushing shell 11 is provided with support components on both sides at both ends;

[0033] The second crushing housing 11 has a motor mounting bracket 3 on its side. The drive motor 4 is located on the side of the motor mounting bracket 3. The output shaft of the drive motor 4 passes through the motor mounting bracket 3 and the second crushing housing 11 and is connected to the crushing end of the second crushing component. The transmission shaft of the first crushing component passes through the side of the first crushing housing 8 and is coaxially connected to the first transmission wheel 1. The output shaft of the drive motor 4 is located between the second crushing housing 11 and the motor mounting bracket 3 and is coaxially connected to the second transmission wheel 20. The first transmission wheel 1 and the second transmission wheel 20 are connected by a transmission belt 2.

[0034] In this invention, when in use, the drive motor 4 is started, which drives the crushing end of the second crushing component to rotate. The output shaft of the drive motor 4, when rotating, drives the second transmission wheel 20 to rotate. The second transmission wheel 20, when rotating, drives the first transmission wheel 1 to rotate via the transmission belt 2, thereby rotating the crushing end of the first crushing component. At this time, the soil to be repaired is added into the first crushing shell 8 through the feed hopper 7. The crushing end of the first crushing component crushes the soil, which then enters the second connecting shell 14. The medicine then enters through the inlet pipe 9 and is finally sprayed through multiple medicine nozzles 15 into the soil crushed inside the second crushing shaft 19, causing the soil and medicine to mix. This soil containing the medicine enters the second crushing shell 11 for a second crushing, improving the mixing effect and preventing the soil mixed with the medicine from clumping. The soil after the second crushing falls out through the discharge end at the bottom of the second crushing shell 11.

[0035] The liquid inlet of the liquid inlet pipe 9 can draw out the medicine through a water pipe and a corresponding pump body, and then spray the medicine out through multiple medicine nozzles 15 (the water pipe and the corresponding pump body are common technical means in this field, so they are not described in detail in this application document).

[0036] In an optional embodiment, the first crushing assembly includes a first crushing shaft 16 and a first crushing side plate 17. The symmetrically distributed first crushing side plates 17 are disposed on the inner wall of the first crushing housing 8. The first crushing shaft 16 is coaxially rotatably connected between the inner walls of the first crushing housing 8. The drive shaft of the first crushing shaft 16 passes through the side wall of the first crushing housing 8 and is coaxially connected to the first drive wheel 1. The second crushing assembly includes a second crushing side plate 18 and a second crushing shaft 19. The symmetrically distributed second crushing shaft 19 is disposed on the inner wall of the second crushing housing 11. The second crushing shaft 19 is coaxially rotatably connected between the inner walls of the second crushing housing 11. The output shaft of the drive motor 4 passes through the motor mounting bracket 3 and the second crushing housing 11 and is coaxially connected to one end of the second crushing shaft 19.

[0037] It should be noted that when the drive motor 4 is started, the drive motor 4 can drive the second crushing shaft 19 to rotate, and when the output shaft of the drive motor 4 rotates, it can drive the second transmission wheel 20 to rotate. When the second transmission wheel 20 rotates, it can drive the first transmission wheel 1 to rotate. When the first transmission wheel 1 rotates, it can drive the first crushing shaft 16 connected to it to rotate. When soil enters the interior of the first crushing shell 8, the soil inside the first crushing shell 8 can be crushed through the symmetrically distributed first crushing side plates 17 and the rotating first crushing shaft 16. When soil enters the interior of the second crushing shell 11, the soil inside the second crushing shell 11 can be crushed through the symmetrically distributed second crushing side plates 18 and the rotating second crushing shaft 19.

[0038] In an optional embodiment, the inner wall of the second connecting housing 14 is larger than the outlet of the first crushing housing 8, the spray end of the liquid spray nozzle 15 is located below the inner top wall of the second connecting housing 14, and the inner top wall of the first connecting housing 10 is smoothly inclined.

[0039] It should be noted that when soil falls out through the first crushing shell 8, it can enter the interior of the second crushing shell 11 through the second connecting shell 14 and the first connecting shell 10. Since the spray end of the liquid spray nozzle 15 is located below the inner top wall of the second connecting shell 14, it prevents soil from falling onto the liquid spray nozzle 15. In addition, the inner top wall of the first connecting shell 10 is smoothly inclined, so that the soil falling onto the first connecting shell 10 can slide down.

[0040] In an optional embodiment, reinforcing plates 5 are provided on both sides of the upper surface of the motor mounting bracket 3 and on the side of the second crushing shell 11.

[0041] It should be noted that the reinforcing plates 5 on both sides improve the effect of fixing the motor mounting bracket 3 to the second crushing shell 11.

[0042] In an optional embodiment, a discharge pipe 6 is provided at the outlet at the bottom of the second crushing shell 11.

[0043] It should be noted that the soil, after being thoroughly mixed with the medicine, will eventually fall out through discharge pipe 6.

[0044] In an optional embodiment, the support assembly includes support rods 13, side plates 12 are symmetrically arranged on both sides of the second crushing shell 11, and a plurality of support rods 13 are vertically spaced at the bottom of the side plates 12.

[0045] It should be noted that multiple support rods 13 can support the side plates 12, and the side plates 12 on both sides can support the second crushing shell 11.

[0046] 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.
