Abstract
Description
Technical Field
[0001] This application relates to the field of soil heavy metal pollution remediation, and in particular to a device for remediating soil heavy metal pollution. Background Technology
[0002] Heavy metals are a prominent inorganic pollutant in soil, primarily because they cannot be decomposed by soil microorganisms and tend to accumulate, transforming into more toxic methyl compounds. Some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health. There are two main approaches to remediating heavy metal pollution in soil: one is to alter the form of heavy metals in the soil, fixing them and reducing their mobility and bioavailability in the environment; the other is to remove heavy metals from the soil. For these two remediation approaches, leaching equipment is commonly used to treat soil contaminated with heavy metals. In conventional leaching equipment, after the base frame is stably installed, a rotating drum is mounted on top of the frame. One end of the drum is connected to a feed hopper. Soil is moved into the feed hopper using a conveyor system. After entering the rotating drum, the soil is rotated and dispersed before being discharged, dispersing any stones within the soil. Finally, the remaining soil is sent into the leaching structure for further treatment.
[0003] Regarding the aforementioned technologies, the inventors believe that conventional soil contains relatively soft, long, and thin objects such as weeds and tree roots, which can easily become entangled with the soil after entering the rotating drum, making it difficult to separate the soil. This requires manual post-processing, increasing the difficulty of soil separation and reducing the effectiveness of the device.
[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
[0005] To address the problem of conventional soil remediation caused by weeds and tree roots, this application provides a device for treating heavy metal pollution in soil.
[0006] The device for treating heavy metal pollution in soil provided in this application adopts the following technical solution:
[0007] A device for treating heavy metal pollution in soil includes a base and a sliding frame. A rotating cylinder is rotatably mounted on the top of the base, and a feed box is fixedly connected to the top of the base. One end of the feed box is connected to one end of the rotating cylinder. Two rotating rods are rotatably mounted on the inner wall of the sliding frame. The two rotating rods are symmetrically distributed about the sliding frame, and several cleaning frames are fixedly connected to the surface of the rotating rods. A rotating motor is fixedly mounted on one end of each rotating rod. The inner wall of the sliding frame is slidably connected to the top of the feed box. The several cleaning frames are evenly distributed on the surface of the rotating rods. One end of the rotating motor is fixedly mounted to the surface of the sliding frame via a frame.
[0008] Preferably, both ends of the sliding frame are fixedly connected to a discharge hopper, the inner wall of the discharge hopper is fixedly installed with a shielding net, and the bottom end of the discharge hopper is connected to a connecting box, the bottom end of the connecting box being fixedly connected to the surface of the feed box.
[0009] Preferably, a sliding frame is slidably connected to the inner wall of the discharge hopper, and a telescopic rod is fixedly installed at both ends of the sliding frame, with one end of the telescopic rod being fixedly connected to the surface of the discharge hopper.
[0010] Preferably, the dimensions of the inner wall of the sliding frame are adapted to the dimensions of the top of the feed box, and two vibration motors are fixedly installed on the surface of the sliding frame.
[0011] Preferably, a plurality of fixing rods are welded to the bottom end of the sliding frame. The surface of the fixing rods is slidably connected to the inner wall of the feed box. The plurality of fixing rods are divided into two groups, and the two groups of fixing rods are symmetrically distributed about the sliding frame. A plurality of springs are fixedly installed between the sliding frame and the feed box, and the center of the springs is on the same straight line as the center of the fixing rod.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. A sliding frame is installed on top of the feed hopper. A rotating rod is rotatably connected to the inner wall of the sliding frame. Several cleaning frames are fixedly connected to the surface of the rotating rod, and a rotating motor is fixedly installed at one end of the rotating rod. This allows the rotating rod to be rotated by the rotating motor, thereby controlling the cleaning frames to separate the soil added from the feed hopper and remove weeds and tree roots from the soil. Discharge hoppers are installed at both ends of the sliding frame. A shielding net is installed on the inner wall of the discharge hopper. A connecting box is connected to the discharge hopper near the shielding net. The bottom end of the connecting box is connected to the surface of the feed hopper, so that the discharged weeds and soil can be discharged through the discharge hopper. The soil is poured out, and a screen net is used to sift the soil mixed with weeds and tree roots into the connecting box. The connecting box then sends the soil back into the feeding box. A sliding frame is slidably connected to the inner wall of the discharge hopper. Both ends of the sliding frame are equipped with telescopic rods, one end of which is connected to the surface of the discharge hopper. This allows the sliding frame to slide along the inner wall of the discharge hopper using the telescopic rods. After the cleaning frame pours in the weeds and tree roots, the sliding frame and the inner wall of the cleaning frame work together to separate the tangled weeds and tree roots, preventing excessive soil from remaining in the weeds and tree roots. Compared with existing technologies, this method effectively improves the treatment efficiency of heavy metal contaminated soil.
[0014] 2. Two vibration motors can also be installed on the surface of the sliding frame. The vibration generated when the vibration motors are started can be used to control the sliding frame to shake at the top of the feed box, thereby dispersing the soil when it is added to the feed box and improving the cleaning effect of the cleaning frame on weeds and tree roots. A fixing rod is welded to the bottom of the sliding frame. The surface of the fixing rod is slidably connected to the inner wall of the feed box, and a spring is installed between the sliding frame and the feed box to support the bottom of the sliding frame. This enhances the vibration effect of the sliding frame when the vibration motors are started, effectively improving the performance of the device. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.
[0021] This application discloses an apparatus for treating heavy metal pollution in soil, referring to... Figure 1 - Figure 2 The system includes a base 1. During use, after the base frame is installed stably, a rotating cylinder 2 is rotatably installed on the top of the base frame. One end of the rotating cylinder 2 is connected to a feed box 3. Soil is moved into the feed box 3 by means of a conveying device. A sliding frame 4 is installed on the top of the feed box 3. A rotating rod 6 is rotatably connected to the inner wall of the sliding frame 4. Several cleaning frames 5 are fixedly connected to the surface of the rotating rod 6, and a rotating motor 7 is fixedly installed on one end of the rotating rod 6. After the rotating rod 6 is rotated by the rotating motor 7, the cleaning frames 5 are operated to separate the soil added from the feed box 3, removing weeds and tree roots in the soil, which effectively improves the treatment efficiency of heavy metal contaminated soil. After the soil enters the rotating cylinder 2 from the feed box 3, it is rotated and dispersed before being discharged. Stones in the soil are dispersed. Finally, the remaining soil is sent into the rinsing structure for treatment.
[0022] Reference Figure 2 Both ends of the sliding frame 4 are equipped with discharge hoppers 8. The inner wall of the discharge hopper 8 is equipped with a shielding net 9. The discharge hopper 8 is connected to a connecting box 10 near the shielding net 9. The bottom end of the connecting box 10 is connected to the surface of the feed box 3. The discharge hopper 8 is used to pour out the cleaned weeds and soil, and the shielding net 9 is used to sieve the soil mixed with the weeds and tree roots into the connecting box 10. The connecting box 10 is used to send the soil back into the feed box 3. The inner wall of the discharge hopper 8 is slidably connected to a sliding frame 11. Both ends of the sliding frame 11 are equipped with telescopic rods 12. One end of the telescopic rod 12 is connected to the surface of the discharge hopper 8. The telescopic rod 12 is used to control the sliding frame 11 to slide on the inner wall of the discharge hopper 8. After the cleaning frame 5 pours in the weeds and tree roots, the sliding frame 11 and the inner wall of the cleaning frame 5 are intersected to separate the tangled weeds and tree roots, avoiding the presence of too much soil in the weeds and tree roots, and effectively improving the use effect of the device.
[0023] Reference Figure 3 - Figure 4 Two vibration motors 13 are installed on the surface of the sliding frame 4. The vibration generated when the vibration motors 13 are started controls the sliding frame 4 to shake at the top of the feed box 3, thereby dispersing the soil when it is added to the feed box 3 and improving the cleaning effect of the cleaning frame 5 on weeds and tree roots. A fixing rod 14 is welded to the bottom of the sliding frame 4. The surface of the fixing rod 14 is slidably connected to the inner wall of the feed box 3. A spring 15 is installed between the sliding frame 4 and the feed box 3. The spring 15 supports the bottom of the sliding frame 4, so that when the vibration motors 13 are started, the sliding frame 4 can move up and down on the surface of the feed box 3, thereby improving the vibration effect of the sliding frame 4.
[0024] The implementation principle of the soil heavy metal pollution treatment device according to this application embodiment is as follows: A sliding frame 4 is installed on the top of the feed box 3. A rotating rod 6 is rotatably connected to the inner wall of the sliding frame 4. Several cleaning frames 5 are fixedly connected to the surface of the rotating rod 6, and a rotating motor 7 is fixedly installed at one end of the rotating rod 6. This allows the rotating rod 6 to be rotated by the rotating motor 7, thereby controlling the cleaning frames 5 to separate the soil added from the feed box 3 and remove weeds and tree roots from the soil. Discharge hoppers 8 are installed at both ends of the sliding frame 4. A shielding net 9 is installed on the inner wall of the discharge hopper 8. A connecting box 10 is connected to the discharge hopper 8 near the shielding net 9. The bottom end of the connecting box 10 is connected to the feed box 3. The surface of box 3 is open to allow the cleaned weeds and soil to be poured out using the discharge hopper 8. The soil mixed with the weeds and tree roots is sieved into the connecting box 10 using the shielding net 9. The soil is then sent back into the feed box 3 using the connecting box 10. A sliding frame 11 is slidably connected to the inner wall of the discharge hopper 8. Telescopic rods 12 are installed at both ends of the sliding frame 11. One end of the telescopic rod 12 is connected to the surface of the discharge hopper 8 so that the sliding frame 11 can be controlled to slide on the inner wall of the discharge hopper 8 using the telescopic rod 12. After the cleaning frame 5 pours in the weeds and tree roots, the sliding frame 11 and the inner wall of the cleaning frame 5 are intersected to separate the tangled weeds and tree roots, avoiding the presence of too much soil in the weeds and tree roots.
[0025] Two vibration motors 13 can also be installed on the surface of the sliding frame 4 so that the vibration generated when the vibration motor 13 is started can be used to control the sliding frame 4 to shake at the top of the feed box 3, thereby dispersing the soil when it is added to the feed box 3 and improving the cleaning effect of the cleaning frame 5 on weeds and tree roots. A fixing rod 14 is welded to the bottom of the sliding frame 4. The surface of the fixing rod 14 is slidably connected to the inner wall of the feed box 3, and a spring 15 is installed between the sliding frame 4 and the feed box 3 so that the sliding frame 4 can be pushed by the spring 15, thereby improving the vibration effect of the sliding frame 4 when the vibration motor 13 is started.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
