Description

Technical Field

[0001] This utility model relates to the field of soil remediation, and in particular to a remediation treatment device for soil pollution control. Background Technology

[0002] In soil remediation, many technologies have specific requirements regarding soil particle size. For example, thermal desorption equipment requires soil to be broken down to a suitable particle size to ensure sufficient contact between soil particles and the thermal medium, thereby improving thermal desorption efficiency. Chemical oxidation equipment also requires a suitable particle size so that the oxidant can penetrate the soil uniformly and react fully with pollutants. Therefore, before soil remediation, the soil particle size needs to be within the range required by the remediation equipment to create favorable conditions for subsequent remediation processes.

[0003] However, the soil may contain impurities such as stones, bricks, and glass fragments. These impurities may hinder the normal operation of the crushing equipment during the crushing process, resulting in some soil clods not being completely crushed. This could lead to the presence of large soil particles in the crushed soil, which would affect the normal operation of the remediation equipment and the remediation effect. To reduce the interference of large soil particles on the remediation process, we propose a remediation treatment device for soil pollution control. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is that existing equipment is inconvenient for screening large soil particles, thus interfering with the remediation process.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a soil pollution remediation treatment device, which includes a support frame, a crushing component disposed on the support frame, including a hopper connected to the support frame and a crushing component disposed in the hopper for crushing polluted soil, and the hopper is constructed with an inlet for feeding and an outlet for discharging, and a screening component located below the outlet and connected to the support frame, including a receiving component fixed to the support frame and a screening component for distinguishing impurities.

[0020] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0022] This embodiment provides a remediation treatment device for soil pollution control, such as... Figure 1 As shown, the support frame 1 is equipped with a hopper 21 for discharging contaminated soil. The hopper 21 is also equipped with a crushing component 24 for crushing the soil. Below the hopper 21, a receiving component 31 and a screening component 32 are installed for discharging and screening the crushed soil. The screening component 32 has several screening holes 33. Below the screening component 32, there is a discharge inclined plate 34. The discharge inclined plate 34 has a discharge port 35 located away from the receiving component 31.

[0023] Soil remediation refers to the process of removing or reducing the concentration of harmful substances in soil, or converting them into harmless substances, through physical, chemical, or biological methods, thereby restoring the soil to its normal function. In some chemical or physical remediation methods, to accelerate the remediation efficiency of contaminated soil, it is often pre-treated by crushing it into fine particles before remediation. In this scheme, workers can first feed the contaminated soil into the hopper 21 through the inlet 22, where it is crushed by the crushing component 24 installed in the hopper 21. The crushed soil is then fed into the receiving component 31 through the outlet 23 of the hopper 21. Figure 4As shown, both the receiving component 31 and the screening component 32 are inclined and connected together. Therefore, the crushed soil falling onto the receiving component 31 will slide into the screening component 32 under its own gravity. Since the screening component 32 is provided with screening holes 33, soil particles with a diameter smaller than the diameter of the screening holes 33 will directly pass through the screening holes 33 and fall onto the discharge inclined plate 34. They will then leave the equipment through the discharge port 35 provided on the discharge inclined plate 34, completing the pretreatment of the contaminated soil. Meanwhile, some larger soil clods in the screening component 32 will continue to fall along the screening component 32 and then leave the screening component 32, waiting for the next crushing. This completes the screening of soil particles of different sizes and avoids the situation where large soil clods affect soil remediation.

[0024] like Figure 4 and Figure 5 As shown, a guide 37 is fixedly installed at one end of the receiving part 31 near the screening part 32. The end of the screening part 32 opposite to the receiving part 31 is provided with a guide ring groove 38 for the guide 37 to slide. The setting of the guide ring groove 38 and the guide 37 makes the screening part 32 and the receiving part 31 rotatably connected. The screening part 32 is provided with a spiral guide plate 36 inside. When the screening part 32 is rotated, the crushed soil entering the screening part 32 will move along the bolt guide plate and will not pass through the screening part 32 quickly. This increases the time the crushed soil spends in the screening part 32 and the contact area with the inner wall of the screening part 32, thereby improving the screening quality of the screening part 32 and preventing some smaller particles from being carried out by larger soil particles.

[0025] like Figure 4 As shown, crushing roller 241 and crushing roller 242 are interlocked. When they rotate, they crush the soil inside the hopper 21, so that the soil particle size reaches the range required by the remediation equipment, creating favorable conditions for subsequent remediation processes.

[0026] like Figure 2 and Figure 3 As shown, a drive motor 41 is provided on the support frame 1, and a worm gear 42 is provided at the output end of the drive motor 41. The worm gear 42 meshes with a worm wheel 43 that is coaxially fixed on the screening component 32. Therefore, when the drive motor 41 runs, it will drive the worm gear 42 to rotate synchronously. The worm gear 42 will drive the screening component 32 to rotate through meshing with the worm wheel 43, thereby causing the soil in the screening component 32 to move synchronously and increasing the screening quality of the crushed soil.

[0027] like Figure 1 and Figure 2As shown, the end of the worm gear 42 away from the drive motor 41 is provided with a transmission component 44 that is connected to the crushing roller 241. Therefore, when the worm gear 42 rotates, it will drive the crushing roller 241 to rotate together through the transmission component 44. Since the ends of the crushing roller 241 and the crushing roller 242 away from the transmission component 44 are coaxially fixed with the drive sprocket 45 and the drive sprocket 46, and the drive sprocket 46 is provided with auxiliary sprockets 47 that are rotatably connected to the support frame 1 on both the upper and lower sides, and the drive sprocket 45, the drive sprocket 26 and the auxiliary sprocket 47 are externally meshed with the drive chain 48, when the crushing roller 241 rotates, the mechanical transmission between the drive sprocket 45, the drive sprocket 26, the auxiliary sprocket 47 and the drive chain 48 will synchronously drive the crushing roller 242 to rotate, thereby realizing the crushing treatment of the contaminated soil in the hopper 21.

[0028] As a further improvement in this embodiment, the winding shape of the drive chain 48 on the drive sprocket 45, drive sprocket 46 and auxiliary sprocket 47 is set to V-shape. This setting allows the crushing roller 241 and the crushing roller 242 to rotate in opposite directions, which significantly increases the relative speed of the soil between the crushing roller 241 and the crushing roller 242. This means that the soil is subjected to stronger shearing and squeezing forces between the crushing roller 241 and the crushing roller 242, thus it can be crushed more quickly, increasing the crushing effect of the contaminated soil.

[0029] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
