Description

Technical Field

[0001] This utility model relates to the field of soil pollution leaching, specifically a leaching device for soil pollution treatment. Background Technology

[0002] Soil pollution control is crucial in the fields of environmental engineering and soil remediation. When soil contains too many harmful substances, exceeding its self-purification capacity, it will cause changes in the composition, structure and function of the soil, inhibit microbial activity, and allow harmful substances or their decomposition products to gradually accumulate in the soil, thereby damaging the environment and ecology.

[0003] In existing technologies, soil leaching equipment is typically used to chemically and physically treat contaminated soil for remediation. This involves injecting chemical solvents that dissolve or migrate soil pollutants into the contaminated soil, thereby dissolving, separating, and treating the pollutants. During soil leaching, the soil enters the equipment through the feed inlet. Large stones often exist in the soil, and these stones can clog the feed inlet as they fall, thus reducing the leaching efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, when leaching soil, the soil enters the leaching equipment through the feed inlet. The soil often contains large stones, which can block the feed inlet as they fall, thus reducing the leaching efficiency. This invention proposes a leaching device for soil pollution treatment.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a leaching device for soil pollution treatment, including a leaching device, wherein a double crushing mechanism is provided on the top of the leaching device;

[0006] The dual crushing mechanism includes a holding shell, the bottom of which is fixedly connected to the top of the washing equipment. A support plate is fixedly connected to one side of the holding shell, and a motor is fixedly connected to the inner cavity of the support plate. A first synchronous pulley is fixedly connected to the output shaft of the motor. A crushing roller is rotatably connected to the inner cavity of the holding shell, with one side of the crushing roller extending through to one side of the holding shell. One side of the crushing roller is fixedly connected to one side of the first synchronous pulley. A pressing roller is rotatably connected to the inner cavity of the holding shell, with one side of the pressing roller extending through to one side of the holding shell. A gear is rotatably connected to one side of the holding shell, with one side of the gear fixedly connected to one side of the pressing roller. A second synchronous pulley is fixedly connected to one side of the gear. A synchronous belt is mounted on the surfaces of the second and first synchronous pulleys for transmission.

[0007] Preferably, the inner cavity of the container is provided with a sliding groove, and a filter plate is slidably connected to the inner cavity of the sliding groove.

[0008] Preferably, the surface of the rolling roller is provided with a guide plate, and one side of the guide plate is fixedly connected to the inner cavity of the container.

[0009] Preferably, the surface of the container is provided with a maintenance groove, and a door panel is movably hinged to one side of the container via a hinge.

[0010] Preferably, the inner cavity of the holding shell is provided with a hollow groove, and a round rod is rotatably connected to the inner cavity of the hollow groove. One side of the round rod is fixedly connected to one side of the rolling roller.

[0011] Preferably, a connecting plate is provided on one side of the synchronous belt, one side of the connecting plate is rotatably connected to one side of the second synchronous pulley, a support rod is fixedly connected to one side of the connecting plate, and one side of the support rod is fixedly connected to one side of the holding shell.

[0012] Preferably, the surface of the motor is provided with a baffle, one side of which is movably hinged to the top of the support plate via a hinge.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a motor to drive a first synchronous wheel and a crushing roller to rotate. The crushing roller rotates and poundes the soil falling into the container, crushing larger stones in the soil. This prevents stones from clogging the feed inlet when entering the washing equipment, thus reducing the subsequent washing efficiency. The rotation of the first synchronous wheel drives a synchronous belt, which in turn drives a second synchronous wheel. The second wheel, in turn, drives a gear to rotate. There are two gears and two crushing rollers; when one gear rotates, it drives the other gear to rotate relative to it. These two gears drive two crushing rollers to rotate relative to each other, crushing the falling soil. This secondary crushing further crushes the stones in the soil, improving the stone crushing effect. This solves the problem that when soil enters the washing equipment through the feed inlet, large stones often clog the feed inlet, reducing washing efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a rinsing device for soil pollution remediation. (Refer to...) Figure 1-3A soil leaching device for remediation includes a leaching unit 1. The top of the leaching unit 1 is equipped with a double crushing mechanism 2. The leaching unit 1 can be used to chemically and physically treat contaminated soil, thereby leaching the soil to reduce pollutants and aid in soil remediation. The double crushing mechanism 2 can double-crush larger stones in the soil, preventing them from clogging the feed inlet of the leaching unit 1 and affecting the soil's entry into the leaching unit 1, thus impacting the leaching efficiency. The working principle of the leaching unit 1 is as follows: the leaching unit 1 transfers pollutants from the solid phase of the soil to the liquid phase through physical and chemical actions. It uses a vibrating screen or hydrocyclone to classify the soil by particle size. Coarse particles, due to their small specific surface area and low pollutant adsorption capacity, can be directly backfilled after rinsing with clean water. Fine particles, due to their large specific surface area and high organic matter content, become the main carriers for pollutant enrichment and need to enter the rinsing reaction unit for deep treatment. Subsequently, rinsing agents are added to the fine particle sludge to change the form of pollutants through chemical reactions. Then, centrifuges, filter presses, or settling tanks are used to separate the rinsed sludge into solid and liquid components. The separated clean water can be recycled for rinsing liquid preparation, reducing water consumption. The separated fine particle sludge needs further treatment to avoid secondary pollution. Finally, the rinsing wastewater is treated in a targeted manner to ensure that it meets discharge standards or is reused. Since rinsing equipment 1 is existing technology, it will not be described in detail here.

[0024] The dual crushing mechanism 2 includes a holding shell 201, the bottom of which is fixedly connected to the top of the washing equipment 1. A support plate 202 is fixedly connected to one side of the holding shell 201. A motor 203 is fixedly connected to the inner cavity of the support plate 202. A first synchronous pulley 204 is fixedly connected to the output shaft of the motor 203. A crushing roller 205 is rotatably connected to the inner cavity of the holding shell 201. One side of the crushing roller 205 extends through to one side of the holding shell 201. One side of the crushing roller 205 is fixed... A rolling roller 206 is rotatably connected to one side of the first synchronous pulley 204 and the inner cavity of the container 201. One side of the rolling roller 206 extends through to one side of the container 201. A gear 207 is rotatably connected to one side of the container 201. One side of the gear 207 is fixedly connected to one side of the rolling roller 206. A second synchronous pulley 208 is fixedly connected to one side of the gear 207. The surfaces of the second synchronous pulley 208 and the first synchronous pulley 204 are jointly fitted with a synchronous belt 209.

[0025] The holding shell 201 can be used to hold the soil to be washed, so that larger stones in the soil can be crushed in the subsequent process. The support plate 202 is U-shaped and can be used to support the motor 203, so that the motor 203 can operate stably. The output shaft of the motor 203 is connected to the first synchronous pulley 204, which can drive the first synchronous pulley 204 to rotate. One side of the first synchronous pulley 204 is connected to the crushing roller 205, and the surface of the first synchronous pulley 204 is fitted with a synchronous belt 209 through toothed meshing. The rotation of the first synchronous pulley 204 can drive the crushing roller 205 to rotate together, and also drive the synchronous belt 209 to drive the transmission. The surface of the crushing roller 205 is equipped with multiple crushing hammers, which can rotate and hammer the larger stones in the soil, thereby crushing the stones and preventing the larger stones from clogging the soil. The feed inlet of the leaching equipment 1 affects the subsequent leaching efficiency of the soil. When the synchronous belt 209 is driven, it will drive the second synchronous wheel 208 to rotate through the meshing of the teeth. When the second synchronous wheel 208 rotates, it will drive the gear 207 to rotate synchronously. There are two gears 207, and the teeth of the two gears 207 mesh with each other. When one gear 207 rotates, it will drive the other gear 207 to rotate relative to it. When the two gears 207 rotate, they will further drive the two crushing rollers 206 to rotate relative to each other inside the holding shell 201. The relative rotation of the two crushing rollers 206 can further crush and crush the stones in the soil, thereby improving the crushing effect of the stones and thus improving the leaching efficiency of the soil.

[0026] Reference Figure 2 The inner cavity of the holding shell 201 is provided with a sliding groove 3, and a filter plate 4 is slidably connected to the inner cavity of the sliding groove 3. The sliding groove 3 is opened to the inner wall of the holding shell 201, and there are two of them, which can be used to place the filter plate 4. The surface of the filter plate 4 is provided with a circular groove, which can filter out large stones in the crushed soil and further screen the soil.

[0027] Reference Figure 4 The surface of the crushing roller 206 is provided with a guide plate 5. One side of the guide plate 5 is fixedly connected to the inner cavity of the container 201. There are two guide plates 5, which are located on the upper part of the two crushing rollers 206 respectively. They can concentrate the soil and stones falling inside the container 201 to the middle of the two crushing rollers 206 through their own inclined surfaces, so that the two crushing rollers 206 can fully crush the stones in the soil for a second time and further improve the crushing effect of the stones.

[0028] Reference Figure 1 and Figure 4The surface of the container 201 is provided with a maintenance groove 6. A door panel 7 is movably hinged to one side of the container 201 via a hinge. The maintenance groove 6 extends to one side of the container 201, through which the filter plate 4 can be pulled out, thereby facilitating subsequent treatment of the soil and stones on the filter plate 4. The inside of the container 201 can also be inspected through the maintenance groove 6. The door panel 7 is hinged to one side of the container 201 via a hinge, which can enclose the maintenance groove 6 to prevent soil from leaving through the maintenance groove 6, thereby reducing the leaching rate of the soil.

[0029] Reference Figure 3 The inner cavity of the holding shell 201 is provided with a hollow groove 8. A round rod 9 is rotatably connected to the inner cavity of the hollow groove 8. One side of the round rod 9 is fixedly connected to one side of the crushing roller 206. There are two sets of hollow grooves 8 and round rods 9. The hollow groove 8 is opened to the inner wall of the holding shell 201 and can be used to install the round rod 9, which can facilitate the rotation of the round rod 9 inside. One side of the round rod 9 is connected to the crushing roller 206, which can support one side of the crushing roller 206, so that the synchronous belt 209 can rotate stably to crush and pulverize the stones, and improve the rotational stability of the crushing roller 206.

[0030] Reference Figure 2 A connecting plate 10 is provided on one side of the synchronous belt 209. One side of the connecting plate 10 is rotatably connected to one side of the second synchronous pulley 208. A support rod 11 is fixedly connected to one side of the connecting plate 10. One side of the support rod 11 is fixedly connected to one side of the holding shell 201. The connecting plate 10 can be used to limit one side of the synchronous belt 209 to prevent the synchronous belt 209 from disengaging from the second synchronous pulley 208 due to external factors, and further prevent the synchronous belt 209 from moving forward. One side of the support rod 11 is fixed to one side of the holding shell 201 to support the connecting plate 10.

[0031] Reference Figure 1 and Figure 2 A baffle 12 is provided on the surface of the motor 203. One side of the baffle 12 is hinged to the top of the support plate 202 via a hinge. The baffle 12 is hinged to the upper part of the support plate 202 to protect the motor 203 from falling soil and damaging it. The baffle 12 can also be rotated open to facilitate the inspection and maintenance of the motor 203.

[0032] Working Principle: When using this device to remediate contaminated soil through leaching, the motor 203 is started first. Then, the soil is poured into the container 201. The output shaft of the motor 203 drives the first synchronous pulley 204 and the crushing roller 205 to rotate together. The crushing roller 205 has multiple crushing hammers on its surface. By engaging with the inner wall of the container 201, it can rotate and crush the soil falling inside the container 201, thereby crushing larger stones in the soil. This prevents larger stones from clogging the feed inlet when entering the leaching equipment 1, thus affecting the soil's entry into the leaching equipment 1 and reducing the subsequent leaching efficiency. When the first synchronous pulley 204 rotates with the motor 203, it engages with the teeth of the synchronous belt 209, which is fitted onto the surface of the first synchronous pulley 204, driving the synchronous belt 209 for transmission. The synchronous belt 209 then engages with the teeth of the second synchronous pulley 208. The teeth mesh, which in turn drives the second synchronous wheel 208 to rotate. The rotation of the second synchronous wheel 208 also drives the gear 207 to rotate. There are two gears 207 and two rolling rollers 206. When one gear 207 rotates, it meshes with the teeth of the other gear 207, which drives the other gear 207 to rotate relative to it. Then, the two gears 207 drive the two rolling rollers 206 to rotate relative to each other inside the holding shell 201 to crush the fallen soil. At this time, the two rolling rollers 206 perform secondary crushing of the soil, further crushing and crushing the stones in the soil, improving the crushing effect of the stones, and thus improving the soil washing efficiency. This solves the problem that when soil enters the washing equipment 1 through the feed inlet, the soil often contains large stones. These large stones may block the feed inlet as they fall, thus reducing the soil washing efficiency.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
