Description

Technical Field

[0001] The invention relates to the field of contaminated soil treatment equipment, in particular to an optimized treatment equipment for contaminated soil. Background Art

[0002] With the acceleration of industrialization and the frequent human activities, soil pollution has become increasingly serious and has become a global environmental challenge. The development of the petrochemical industry, improper disposal of industrial waste, excessive use of pesticides and fertilizers, and leakage during transportation have all led to a large number of harmful substances such as petroleum hydrocarbons, heavy metals, and organic pollutants (such as benzene, polycyclic aromatic hydrocarbons, etc.) entering the soil environment, seriously damaging the ecological function and quality of the soil, and posing a huge threat to human health, agricultural production and ecological balance.

[0003] Traditional methods for the treatment of contaminated soil mainly include physical remediation, chemical remediation and biological remediation. Physical remediation methods such as soil import method and soil leaching method can remove pollutants in the soil to a certain extent, but they have problems such as high cost, great damage to soil structure and possible secondary pollution. Chemical remediation methods such as chemical oxidation method and solidification stabilization method have relatively obvious remediation effects, but the use of chemical agents may change the physical and chemical properties of the soil and affect the soil fertility and ecosystem. Biological remediation methods such as microbial remediation method and plant remediation method are more environmentally friendly, but the remediation cycle is long and is greatly restricted by soil environmental conditions (such as temperature, humidity, pH, etc.), making it difficult to meet the needs of large-scale and rapid treatment of contaminated soil.

[0004] Under such circumstances, it is particularly urgent to develop an efficient, multifunctional and environmentally friendly contaminated soil treatment equipment. The present invention aims to integrate the advantages of multiple remediation technologies, overcome the shortcomings of traditional treatment methods, and achieve rapid and effective treatment of contaminated soil through innovative mechanical design and process combination, improve the efficiency and quality of soil remediation, reduce treatment costs, and reduce negative impacts on the environment, so as to provide a feasible technical solution to solve the increasingly serious soil pollution problem.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides an optimized treatment device for contaminated soil, such as Figure 1 As shown, it includes a bracket 1, which serves as a supporting frame for the entire equipment and provides a stable foundation for the installation and operation of other mechanisms. A shoveling mechanism 2 is provided on one side of the interior of the bracket 1. Its internal structure is exquisitely designed and is used to dig contaminated soil from the ground. A transportation mechanism 3 is provided in the middle of the bracket 1, which undertakes the important task of transporting the shoveled soil to the treatment area. A treatment mechanism 4 is provided on the other side of the interior of the bracket 1, which is the core part for purifying and repairing the contaminated soil. A suspension frame 5 is fixedly welded at one end of the bracket 1 close to the shoveling mechanism 2. The device can be conveniently hung on the tail of a tractor through the suspension frame 5, so that the device can be moved with the help of the power of the tractor. Rollers 6 are movably installed on both sides of the bottom of the bracket 1 close to the treatment mechanism 4, and the rollers 6 can ensure the flexibility and stability of the device during movement.

[0033] In this embodiment, the shoveling mechanism 2 includes a movable shaft 201, which is precisely and movably mounted on one side of the inner part of the bracket 1, and a plurality of first cams 202 are evenly and fixedly mounted on the outer diameter thereof. The unique shape and movement characteristics of the first cams 202 play a key role in the shoveling process. A connecting rod 203 is movably mounted in the middle of the first cam 202. The connecting rod 203 serves as a connecting component, and a shovel 204 is fixedly mounted at the end thereof. The shovel 204 is made of special material and design, and has good soil entry and shoveling performance.

[0034] Furthermore, a light rod 205 is fixedly installed at a position near the lower side of the movable shaft 201 inside the bracket 1. The light rod 205 provides a stable support for the subsequent installation of the crankshaft 206. Several crankshafts 206 are evenly and movably installed on the outer diameter of the light rod 205, and the ends of the crankshafts 206 are movably installed on the middle outer diameter of the corresponding side connecting rod 203. This connection method enables the movement of the connecting rod 203 to be precisely controlled. A first motor 207 is fixedly installed on one side of the bracket 1 and the driving end of the first motor 207 is fixedly installed on one end of the movable shaft 201. The first motor 207 serves as a power source and provides strong power support for the operation of the entire shoveling mechanism 2.

[0035] Specifically, the first motor 207 is started. After the first motor 207 is powered on, it starts to run and drives the movable shaft 201 to rotate through its driving end. Several first cams 202 on the movable shaft 201 start to make circular motion. Since the middle part of the first cam 202 is movably connected with the connecting rod 203, and the middle part of the connecting rod 203 is limited by the crankshaft 206, the crankshaft 206 is stably guided along the light rod 205, so that the shovel 204 at the bottom continuously makes a curved shovel action. This curved shovel action can effectively shovel the contaminated soil from the ground and lift it onto the conveyor belt 301. Then the conveyor belt 301 is started and starts to run under the drive of the motor or other power devices, transporting the received soil upward and sending it into the processing box 401 through the feed port 405.

[0036] Furthermore, the transport mechanism 3 includes a conveyor belt 301, which is installed in the inner middle part of the bracket 1 at a specific inclination angle to ensure that the soil can be smoothly transported upward. An inclined mounting plate 302 is fixedly installed at a position above the conveyor belt 301 inside the bracket 1, and the mounting plate 302 provides a suitable position for the installation of other components. A first rotating shaft 307 is movably installed at a position near one side of the mounting plate 302 inside the bracket 1, and a plurality of short shafts 303 are movably installed inside the mounting plate 302. A turntable 304 is fixedly installed at the bottom end of the short shaft 303, and steel forks 305 are fixedly welded on both sides of the bottom end of the turntable 304. A first worm gear 306 is fixedly installed at the top end of the short shaft 303, and a plurality of first worm screws 308 are evenly fixedly installed on the outer diameter of the first rotating shaft 307, and the inner ends of the first worm screws 308 are meshedly connected to one side of the first worm gear 306 on the corresponding side. Through this complex and orderly transmission structure, the function of crushing and pre-processing the soil is realized.

[0037] Specifically, when the movable shaft 201 rotates, the first driving wheel 7 fixedly installed at one end thereof also rotates accordingly, and through the transmission action of the first synchronous belt 9, the first driven wheel 8 and the first rotating shaft 307 are driven to rotate. The rotating first rotating shaft 307 drives all the first worm gears 308 to rotate, and the first worm gears 308 mesh with the first worm gear 306 to drive all the first worm gears 306 and the short shaft 303 to rotate, thereby driving the turntable 304 and the steel fork 305 at the bottom of the short shaft 303 to rotate at high speed. The rotation of the turntable 304 and the continuous stirring of the steel fork 305 will break up the soil entering the conveyor belt 301, thereby improving the subsequent processing effect.

[0038] Furthermore, the processing mechanism 4 includes a processing box 401, which is made of a sealed and high-temperature resistant material and is fixedly installed on the other side of the bracket 1. A transmission shaft 406 is movably installed in the middle of the top of the processing box 401 through a bearing mounting seat, and cylinder bodies 407 are fixedly installed at both ends of the transmission shaft 406. The outer diameter of the cylinder body 407 is provided with an inclined ball groove and the outer diameter of the ball groove is movably provided with an inclined bearing seat 408. Swing rods 409 are movably installed on both sides of the interior of the processing box 401 and the top ends of the swing rods 409 are movably installed on the bottom ends of the corresponding side inclined bearing seats 408. The ends of the swing rods 409 are fixedly connected with soil scooping plates 410. This unique structural design enables the soil scooping plates 410 to perform efficient soil turning operations in the processing box 401.

[0039] Specifically, the second motor 412 drives the main shaft 413 to rotate, and the main shaft 413 drives the second worm 414 at the end to rotate. The rotating second worm 414 meshes with the second worm wheel 411 to drive the second worm wheel 411 and the transmission shaft 406 to rotate. The rotating transmission shaft 406 drives the cylinder bodies 407 on both sides to rotate. Since there is a certain angle between the ball groove on the outer diameter of the cylinder body 407 and the central axis of the cylinder body 407, when the cylinder body 407 rotates, it drives the oblique bearing seat 408 on the outer diameter of the ball groove to swing. The swinging oblique bearing seat 408 drives the top end of the swing rod 409 to follow the movement, and the upper outer diameter of the swing rod 409 is movably set on the top wall of the processing box 401. When the top of the swing rod 409 swings, the bottom of the swing rod 409 will produce a swinging effect in the opposite direction, thereby driving the bottom soil scooping plate 410 to swing back and forth, and the soil entering the processing box 401 is continuously scooped up, thereby improving the heating efficiency and heating area of ​​the soil.

[0040] Furthermore, a discharge channel 402 is provided at the inner bottom of the processing box 401, a second rotating shaft 403 is movably installed inside the discharge channel 402, a plurality of soil unloading plates 404 are fixedly installed on the outer diameter of the second rotating shaft 403, and a feed port 405 is provided at the bottom of the processing box 401 close to the transport mechanism 3. The various components work together to ensure that the processed soil can be discharged smoothly.

[0041] Furthermore, a second worm gear 411 is fixedly mounted on the middle outer diameter of the transmission shaft 406, a second motor 412 is fixedly mounted on the top side of the processing box 401, a main shaft 413 is fixedly mounted on the driving end of the second motor 412, a second worm 414 is fixedly mounted on the end of the main shaft 413, and the second worm 414 is meshed and connected with the inner end of the second worm gear 411, thereby providing stable power transmission for the relevant components in the processing mechanism 4.

[0042] Furthermore, a rotating rod 415 is movably installed on one side of the inner top of the processing box 401, and a cross brush plate 416 is fixedly installed on the bottom end of the rotating rod 415. The top end of the rotating rod 415 extends to the outside of the processing box 401 and is fixedly installed with a driven bevel gear 417. A driving bevel gear 418 is fixedly installed on the middle outer diameter of the main shaft 413, and the driving bevel gear 418 is meshed and connected with the inner end of the driven bevel gear 417. Through this gear transmission method, high-speed rotation of the cross brush plate 416 is achieved.

[0043] Furthermore, a repair liquid storage box 419 is fixedly installed on one side of the inner top of the processing box 401 near the rotating rod 415, and a rubber piston 420 is fixedly connected to the top of the repair liquid storage box 419. A return spring 421 is fixedly installed in the middle of the rubber piston 420. A suction pipe 422 is fixedly installed on one side of the interior of the repair liquid storage box 419, and the top of the suction pipe 422 is connected to the interior of the rubber piston 420. A drain pipe 423 is fixedly installed on the other side of the interior of the repair liquid storage box 419. The top is connected to the interior of the rubber piston 420 and the end of the discharge pipe 423 extends to one side of the cross brush plate 416. The inner tops of the suction pipe 422 and the discharge pipe 423 are fixedly installed with rubber one-way valves 424. A second cam 425 is fixedly connected to the outer diameter of one side of the main shaft 413 close to the rubber piston 420. An electric heater 426 is also fixedly installed inside the processing box 401. This design realizes the precise delivery and spraying of the repair liquid. At the same time, the electric heater 426 provides a heat source for the physical repair of the soil.

[0044] Specifically, when the main shaft 413 rotates, it will also drive one end of the second cam 425 to rotate, so that the other end of the second cam 425 continuously compresses the rubber piston 420, and then utilizes the elastic effect of the return spring 421 to make the rubber piston 420 continuously perform compression and lifting movement. When the rubber piston 420 is lifted, the internal air pressure increases, and the external atmospheric pressure opens the rubber one-way valve 424 of the suction pipe 422, and the hydrogen peroxide repair liquid in the repair liquid storage tank 419 is sucked into the rubber piston 420. When the rubber piston 420 is compressed, the internal air pressure decreases, and the external atmospheric pressure closes the rubber one-way valve 424 of the suction pipe 422 and closes the discharge pipe 423. The rubber one-way valve 424 is opened, and the repair liquid in the rubber piston 420 is discharged to the inside of the treatment box 401 through the drain pipe 423. In addition, when the main shaft 413 rotates, it will also drive the active bevel gear 418 to rotate. The rotating active bevel gear 418 will drive the driven bevel gear 417 and the rotating rod 415 to rotate, thereby driving the cross brush plate 416 at the bottom of the rotating rod 415 to rotate at a high speed. The cross brush plate 416 will scatter the repair liquid, and after mixing with the air, it will form a high-speed water-gas fluid, which will be fully mixed with the soil in the treatment box 401. The hydrogen peroxide repair liquid will oxidize and decompose the petroleum hydrocarbon organic pollutants in the soil into harmless substances such as carbon dioxide and water, thereby realizing chemical repair of the soil.

[0045] Furthermore, a first driving wheel 7 is fixedly installed on one end of the movable shaft 201, a first driven wheel 8 is fixedly installed on one end of the first rotating shaft 307, the outer diameters of the first driving wheel 7 and the first driven wheel 8 are connected by a first synchronous belt 9, a second driving wheel 10 is fixedly installed on the other end of the first rotating shaft 307, a second driven wheel 11 is fixedly installed on one end of the second rotating shaft 403, and the outer diameters of the second driving wheel 10 and the second driven wheel 11 are connected by a second synchronous belt 12. Through the combination of these synchronous belts and wheels, power transmission and coordinated work between different mechanisms are realized.

[0046] Working principle: first move the device to the contaminated land, use the suspension frame 5 to hang the device on the tail of the tractor, start the tractor to drag the device to move, first start the first motor 207, the first motor 207 starts to run after being energized, and drives the movable shaft 201 to rotate through its driving end, and the first cams 202 on the movable shaft 201 start to make circular motion. Since the middle part of the first cam 202 is movably connected with the connecting rod 203, and the middle part of the connecting rod 203 is limited by the crankshaft 206, the crankshaft 206 is stably guided along the light rod 205, so that the shovel 204 at the bottom continuously makes a curved shovel action. This curved shovel action can effectively shovel the contaminated soil from the land and lift it to the conveyor belt 301 The conveyor belt 301 is then started. The conveyor belt 301 starts to operate under the drive of a motor or other power device, transports the received soil upward, and sends it into the processing box 401 through the feed port 405. In addition, when the movable shaft 201 rotates, the first driving wheel 7 fixedly installed at one end thereof also rotates accordingly, and through the transmission action of the first synchronous belt 9, the first driven wheel 8 and the first rotating shaft 307 are driven to rotate. The rotating first rotating shaft 307 drives all the first worm gears 308 to rotate, and the first worm gear 308 meshes with the first worm wheel 306 to drive all the first worm wheels 306 and the short shaft 303 to rotate, thereby driving the turntable 304 and the steel fork 305 at the bottom of the short shaft 303 to rotate at high speed. The rotation of the turntable 304 and the continuous stirring of the steel fork 305 will drive the incoming soil. The soil entering the conveyor belt 301 is broken to improve the later treatment effect. When the soil enters the treatment box 401 from the feed port 405, the electric heater 426 is started, and the electric heater 426 starts to heat up to heat the contaminated soil. The heated soil will volatilize and desorb some volatile organic substances such as benzene and toluene in the soil from the surface of the soil particles. Then the second motor 412 is started, and the second motor 412 drives the main shaft 413 to rotate. The main shaft 413 drives the second worm 414 at the end to rotate. The rotating second worm 414 is meshed with the second worm gear 411 to drive the second worm gear 411 and the transmission shaft 406 to rotate. The rotating transmission shaft 406 will drive the cylinder bodies 407 on both sides to rotate. Due to the ball groove on the outer diameter of the cylinder body 407 There is a certain angle with the central axis of the cylinder body 407. When the cylinder body 407 rotates, the oblique bearing seat 408 on the outer diameter of the ball groove will be driven to swing, and the swinging oblique bearing seat 408 will drive the top end of the swing rod 409 to follow the movement, and the upper outer diameter of the swing rod 409 is movably arranged on the top wall of the processing box 401. When the top of the swing rod 409 swings, the bottom of the swing rod 409 will produce a swinging effect in the opposite direction, thereby driving the bottom soil scooping plate 410 to swing back and forth, and the soil entering the processing box 401 will be continuously scooped up, thereby improving the heating efficiency and heating area of ​​the soil, better completing the desorption of volatile organic matter in the soil, and realizing the physical repair of the soil. At the same time, when the main shaft 413 rotates, it will also drive one end of the second cam 425 to rotate.The other end of the second cam 425 continuously compresses the rubber piston 420, and then the elastic effect of the return spring 421 is used to make the rubber piston 420 continuously perform a compression and lifting movement. When the rubber piston 420 is lifted, the internal air pressure increases, and the external atmospheric pressure opens the rubber one-way valve 424 of the suction pipe 422, and the hydrogen peroxide repair liquid in the repair liquid storage tank 419 is sucked into the rubber piston 420. When the rubber piston 420 is compressed, the internal air pressure decreases, and the external atmospheric pressure closes the rubber one-way valve 424 of the suction pipe 422 and opens the rubber one-way valve 424 of the discharge pipe 423, and the repair liquid in the rubber piston 420 is discharged to the inside of the processing box 401 through the discharge pipe 423. In addition, when the main shaft 413 rotates, it will also drive the active bevel gear 418 to rotate, and the rotating active bevel gear 418 will drive the driven bevel gear The gear 417 and the rotating rod 415 rotate, thereby driving the cross brush plate 416 at the bottom of the rotating rod 415 to rotate at a high speed. The cross brush plate 416 will scatter the repair liquid, and after mixing with the air, it will form a high-speed water-gas fluid, which will be fully mixed with the soil in the treatment box 401. The hydrogen peroxide repair liquid will oxidize and decompose the petroleum hydrocarbon organic pollutants in the soil into harmless substances such as carbon dioxide and water, thereby achieving chemical repair of the soil. The repaired soil will enter the discharge channel 402, and the first rotating shaft 307 will also drive the second driving wheel 10 to rotate when rotating, and through the transmission of the second synchronous belt 12, drive the second driven wheel 11 and the second rotating shaft 403 to rotate. The second rotating shaft 403 will drive the unloading plate 404 on the outer diameter to rotate, and the rotating unloading plate 404 will gradually discharge the soil entering the discharge channel 402, so that it falls back onto the land.
