Nowadays, in order to reduce environmental pollution, meet regulatory requirements, improve resource utilization and protect human health, by separating the different particle sizes and components in the contaminated soil, the useful soil part can be recycled and reused to reduce resource waste. Therefore, fine screening can make the treatment process more targeted and improve the treatment effect and efficiency.

The feed hopper slides to the left in the cavity of the support rod through the connecting rod to compress the third spring, so that the feed hopper vibrates, so that the industrial solid hazardous waste contaminated soil attached to the inner wall of the feed hopper vibrates and falls off, effectively reducing some wet contaminated soil remaining on the inner wall of the feed hopper, making the feed hopper faster when feeding, which helps to increase the fluidity of the industrial solid hazardous waste contaminated soil and improve the screening efficiency;

[0018] S3. When the motor is started, multiple screening rollers can be driven to rotate simultaneously through the fourth synchronous belt, the second synchronous belt and the third synchronous belt to screen the industrial solid hazardous waste contaminated soil. The largest contaminated soil enters the first conveyor belt, the medium-sized contaminated soil falls onto the second conveyor belt through the screening holes of the first inclined plate, and the smallest contaminated soil falls onto the fourth synchronous belt through the screening holes of the second inclined plate, thereby achieving fine screening of industrial solid hazardous waste contaminated soil.

[0020] 1. The industrial solid hazardous waste contaminated soil fine screening device starts the motor, drives the rotating rod and the cam to rotate through the first synchronous belt, and the cam contacts the inclined plate, so that the inclined plate pushes the first sliding rod to slide to the left, so that the first sliding rod hits the outer wall of the lower half of the feed hopper, and the feed hopper is automatically reset by the third spring, and then the cam drives the driving plate to contact the second sliding rod to slide to the left, and hits the outer wall of the upper half of the feed hopper, so that the feed hopper vibrates and slides to the left again, and this reciprocating operation makes the feed hopper vibrate repeatedly, so that the moist industrial solid hazardous waste contaminated soil attached to its inner wall vibrates and falls off, which helps to increase the feeding speed of the industrial solid hazardous waste contaminated soil, make it more fluid, reduce the phenomenon of material jamming, and thus improve the screening efficiency.

[0021] 2. The industrial solid hazardous waste contaminated soil fine screening device starts the motor, and through the fourth synchronous belt, the second synchronous belt and the third synchronous belt, it can drive multiple screening rollers to rotate simultaneously to screen the industrial solid hazardous waste contaminated soil. The largest contaminated soil enters the first conveyor belt, the medium-sized contaminated soil falls onto the second conveyor belt through the screening holes of the first inclined plate, and the smallest contaminated soil falls onto the fourth synchronous belt through the screening holes of the second inclined plate, thereby realizing the fine screening of industrial solid hazardous waste contaminated soil.

Then, under the limitation of the slider by the second chute plate, the slider slides horizontally, thereby driving the cylindrical block to slide horizontally, pushing the push rod to slide inside the piston cylinder and push it to the piston plate, so that the water in the piston cylinder is squeezed out from the water outlet pipe into the spray plate, and some dry industrial solid hazardous waste contaminated soil is sprayed with water mist to reduce dust, which effectively reduces the floating of dust and prevents the staff from inhaling it, which helps to protect the health of the staff.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Example 1: Reference Figure 1-Figure 14 The industrial solid hazardous waste contaminated soil fine screening device includes a device housing 1 and a motor 2 arranged on the surface of the device housing 1. A feeding hopper 3 is arranged on the top of the device housing 1. The top of the device housing 1 is fixedly connected with a first fixed plate 4 and a first L-shaped plate 5. It also includes: a rotating rod 6, which is rotatably connected to the first fixed plate 4, and a first synchronous belt 7 is transmission-connected between the rotating rod 6 and the motor 2. A cam 8 is fixedly connected to the inner surface of the rotating rod 6, and a driving plate 801 is fixedly connected to the surface of the cam 8; a second fixed plate 9 is fixedly connected to the top of the device housing 1, and the first L-shaped plate 5 is fixedly connected to the top of the device housing 1. The surface of the second fixed plate 9 is slidably connected to the first sliding rod 10, the right end surface of the first sliding rod 10 is fixedly connected to the inclined plate 11, and the surface of the first sliding rod 10 is sleeved with a first spring 12; the third fixed plate 13 is fixedly connected to the top of the first L-shaped plate 5, the surface of the third fixed plate 13 is slidably connected to the second sliding rod 14, and the second sliding rod 14 is sleeved with a second spring 15; the connecting rod 16 is fixedly connected to the left bottom of the hopper 3, the left side of the connecting rod 16 is slidably connected to the support rod 17, and the support rod 17 is provided with a third spring 18.

[0041] In the present invention, by starting the motor 2, under the action of the first synchronous belt 7, the rotating rod 6 and the cam 8 are driven to rotate. When the cam 8 rotates to the position of the inclined plate 11, it rotates along the inclined surface of the inclined plate 11, so that the inclined plate 11 pushes the first sliding rod 10 to slide to the left, so that the first sliding rod 10 hits the outer wall of the lower half of the feed hopper 3. At the same time, the feed hopper 3 slides into the cavity of the support rod 17 under the support of the connecting rod 16 to compress the third spring 18. Then the cam 8 no longer conflicts with the inclined plate 11, and the inclined plate 11 automatically moves under the action of the first spring 12. After reset, the cam 8 drives the driving plate 801 to rotate to the second sliding rod 14, conflicts with it, causes the second sliding rod 14 to slide to the left, hits the outer wall of the upper part of the feed hopper 3, causes the feed hopper 3 to vibrate and slide to the left again, and then the second spring 15 automatically resets the second sliding rod 14, and the reciprocating operation causes the feed hopper 3 to vibrate repeatedly, causing the moist industrial solid hazardous waste contaminated soil attached to its inner wall to vibrate and fall off, which helps to increase the feeding speed of the industrial solid hazardous waste contaminated soil, make it more fluid, reduce the phenomenon of material jamming, and thus improve the screening efficiency.

[0043] In the present invention, when the feed hopper 3 is hit and slides to the left, the second L-shaped plate 19 can slide inside the first slide plate 20 to make its sliding more stable. The third spring 18 inside the support rod 17 can automatically reset the feed hopper 3 so that it can be hit again to produce shock. At the same time, the third spring 18 can also cause the feed hopper 3 to produce slight shock.

[0044] A mounting plate 22 is fixedly connected to the surface of the device housing 1, the bottom of the motor 2 is fixedly connected to the mounting plate 22, the rotating rod 6 passes through the first fixed plate 4 and is rotatably connected to the first fixed plate 4, the first sliding rod 10 passes through the second fixed plate 9 and is slidably connected to the second fixed plate 9, one end of the first spring 12 is fixedly connected to the second fixed plate 9, and the other end of the first spring 12 is fixedly connected to the inclined plate 11.

[0045] In the present invention, the first sliding rod 10 can be automatically reset by the first spring 12, so that the inclined plate 11 is reset and contacts the cam 8 again. At the same time, the first sliding rod 10 can support and guide the first spring 12 to prevent the first spring 12 from bending.

[0046] The second sliding rod 14 passes through the third fixed plate 13 and is slidably connected to the third fixed plate 13, one end of the second spring 15 is fixedly connected to the second sliding rod 14, the other end of the second spring 15 is fixedly connected to the third fixed plate 13, the cam 8 is slidably connected to the inclined plate 11, and the driving plate 801 is slidably connected to the second sliding rod 14.

[0047] In the present invention, the second sliding rod 14 can be automatically reset after being hit by the second spring 15, so as to collide with the driving plate 801 again next time, and can achieve reciprocating impact on the hopper 3.

[0048] Example 3: Reference Figure 1-Figure 14 , which is basically the same as the first embodiment. Furthermore, a first inclined plate 23 and a second inclined plate 24 are fixedly installed inside the device housing 1, and a plurality of screening rollers 25 are penetrated inside the first inclined plate 23 and the second inclined plate 24 and are rotatably connected to the first inclined plate 23 and the second inclined plate 24. A second synchronous belt 26 and a third synchronous belt 27 are transmission-connected between the plurality of screening rollers 25, and a fourth synchronous belt 28 is transmission-connected between the output end of the motor 2 and the screening rollers 25.

[0049] The first conveyor belt 29 is fixedly connected to the bottom surface of the left end of the first inclined plate 23, the second conveyor belt 30 is fixedly connected to the bottom surface of the left end of the second inclined plate 24, the vertical plate 31 is fixedly connected to the top of the device housing 1, the third conveyor belt 32 is fixedly connected to the top of the vertical plate 31, and the fourth conveyor belt 101 is fixedly passed through the right side surface of the device housing 1. Screening holes are provided on the bottom surfaces of the first inclined plate 23 and the second inclined plate 24, and the screening holes of the first inclined plate 23 are larger than those of the second inclined plate 24.

[0050] In the present invention, the motor 2 is started, and through the fourth synchronous belt 28, the second synchronous belt 26 and the third synchronous belt 27, multiple screening rollers 25 can be driven to rotate simultaneously to screen the industrial solid hazardous waste contaminated soil. The largest contaminated soil enters the first conveyor belt 29, the medium-sized contaminated soil falls onto the second conveyor belt 30 through the screening holes of the first inclined plate 23, and the smallest contaminated soil falls onto the fourth synchronous belt 28 through the screening holes of the second inclined plate 24, thereby realizing the fine screening of the industrial solid hazardous waste contaminated soil.

[0051] Example 4: Reference Figure 1-Figure 14, which is basically the same as the first embodiment. Furthermore, a third L-shaped plate 33 is fixedly connected to the top surface of the right side of the device housing 1, a round rod 34 is rotatably connected to the top surface of the third L-shaped plate 33, a half gear 35 is fixedly connected to one end of the round rod 34 away from the third L-shaped plate 33, a full gear 36 passes through the surface of the rotating rod 6 and is fixedly connected to the rotating rod 6, and the full gear 36 is meshed with the half gear 35.

[0052] In the present invention, the third L-shaped plate 33 can provide support for the round rod 34 during rotation, which helps to make the rotation of the round rod 34 more stable. When the rotating rod 6 rotates, the full gear 36 can be driven to rotate and mesh with the half gear 35, so that the half gear 35 and the round rod 34 rotate together.

[0053] A fourth L-shaped plate 37 is fixedly connected to the surface of the device housing 1, a piston cylinder 38 is fixedly connected to the top of the end of the fourth L-shaped plate 37 away from the device housing 1, a piston plate 39 is connected to the internal piston of the piston cylinder 38, a water outlet pipe 40 is fixedly connected to the right surface of the piston cylinder 38, a water storage barrel 41 is fixedly connected to the bottom of the fourth L-shaped plate 37, a water suction pipe 42 is fixedly connected between the water storage barrel 41 and the piston cylinder 38, a push rod 43 is fixedly connected to the inner surface of the piston plate 39, the push rod 43 penetrates the piston cylinder 38 and is slidably connected to the piston cylinder 38, and a spray plate 44 is fixedly connected to the end of the water outlet pipe 40 away from the piston cylinder 38. One-way valves are fixedly installed inside the water suction pipe 42 and the water outlet pipe 40.

[0054] In the present invention, the piston plate 39 performs piston motion in the piston cylinder 38, so that the water inside the piston cylinder 38 can be discharged through the water outlet pipe 40, and then water is sucked from the water storage barrel 41 through the water suction pipe 42. The one-way valve inside the water outlet pipe 40 and the water suction pipe 42 can prevent water from being squeezed out of the water suction pipe 42 during squeezing, and prevent water from returning to the piston cylinder 38.

[0055] A circular cylinder 45 is fixedly connected to the surface of the half gear 35, an arc-shaped slide groove is opened on the surface of the circular cylinder 45, a cylindrical block 46 is slidably connected inside the circular cylinder 45, a slider 47 is fixedly connected to the top surface of the cylindrical block 46, the slider 47 penetrates the arc-shaped slide groove of the circular cylinder 45 and is slidably connected to the arc-shaped slide groove of the circular cylinder 45, a fifth L-shaped plate 48 is fixedly connected to the top surface of the right side of the device housing 1, a second slide groove plate 49 is fixedly connected to the end of the fifth L-shaped plate 48 away from the device housing 1, the slider 47 is slidably connected in the second slide groove plate 49, a fourth spring 4301 is sleeved on the surface of the push rod 43, one end of the fourth spring 4301 is fixedly connected to the cylindrical block 46, and the other end of the fourth spring 4301 is fixedly connected to the piston cylinder 38.

[0056] In the present invention, the rotation of the half gear 35 drives the circular cylinder 45 to rotate. When the circular cylinder 45 rotates, the arc-shaped slide groove on the surface will also rotate synchronously. Then, under the limitation of the second slide groove plate 49 on the slide block 47, the slide block 47 can only slide in the horizontal direction, thereby driving the cylindrical block 46 to slide in the horizontal direction, pushing the push rod 43 to slide into the piston cylinder 38 and push it to the piston plate 39, so that the water in the piston cylinder 38 is squeezed out from the water outlet pipe 40 into the spray plate 44, and some dry industrial solid hazardous waste contaminated soil is sprayed with water mist to reduce dust, effectively reducing the floating of dust, preventing workers from inhaling it, and helping to protect the health of workers. When the push rod 43 is pushed, it is compressed to the fourth spring 4301. When the half gear 35 rotates to no longer mesh with the full gear 36, the fourth spring 4301 automatically makes the push rod 43 Pull the piston plate 39 to reset, so that the piston cylinder 38 absorbs water from the water storage barrel 41 through the suction pipe 42 and enters the piston cylinder 38 again. At the same time, the push rod 43 automatically causes the cylindrical block 46 to drive the slider 47 to reset along the arc-shaped slide groove of the circular cylinder 45 and the slide groove of the second slide groove plate 49. Then the half gear 35 engages with the full gear 36 again to rotate, and the cylindrical block 46 pushes the push rod 43 again, so that the piston plate 39 squeezes the water inside the piston cylinder 38 again, and enters the spray plate 44 through the outlet pipe 40 to spray mist water, thereby causing the floating industrial solid hazardous waste contaminated soil to fall, effectively reducing the floating dust, and helping to protect the health of the staff. When screening some non-dried industrial solid hazardous waste contaminated soil, the staff can disassemble the half gear 35 without spraying water to reduce dust.

[0057] Example 5: A method for using a device for fine screening of industrial solid hazardous waste contaminated soil, using the following steps:

[0058] S1, start the motor 2, drive the rotating rod 6 to rotate synchronously through the first synchronous belt 7, the rotating rod 6 drives the cam 8 to rotate and contact the inclined plate 11, and the inclined plate 11 pushes the first sliding rod 10 to slide to the left through the inclined surface of the inclined plate 11, and hits the outer wall of the feed hopper 3. The feed hopper 3 slides to the left in the cavity of the support rod 17 through the connecting rod 16 to compress the third spring 18, so that the feed hopper 3 vibrates, so that the industrial solid hazardous waste contaminated soil attached to the inner wall of the feed hopper 3 vibrates and falls off, effectively reducing some moist contaminated soil remaining on the inner wall of the feed hopper 3, so that the feed hopper 3 is faster when feeding, which helps to increase the fluidity of the industrial solid hazardous waste contaminated soil and improve the screening efficiency;

[0059] S2, while the cam 8 rotates, it drives the driving plate 801 to rotate. After the first sliding rod 10 hits the feed hopper 3, the driving plate 801 contacts the second sliding rod 14, so that the second sliding rod 14 hits the outer wall of the upper half of the feed hopper 3 for the second time, which can make the moist industrial solid hazardous waste contaminated soil attached to the entire inner wall of the feed hopper 3 vibrate and fall off. Under the action of the third spring 18, the feed hopper 3 is automatically reset, and the first spring 12 drives the first sliding rod 10 to drive the inclined plate 11 to reset, and the second spring 15 drives the second sliding rod 14 to automatically reset, so that the cam 8 contacts the inclined plate 11 again, and the driving plate 801 contacts the second sliding rod 14 again. This reciprocating operation causes the feed hopper 3 to vibrate repeatedly, effectively reducing the phenomenon of material jamming inside the feed hopper 3, thereby making the screening efficiency of industrial solid hazardous waste contaminated soil higher;

[0060] S3. While starting the motor 2, the fourth synchronous belt 28, the second synchronous belt 26 and the third synchronous belt 27 can drive multiple screening rollers 25 to rotate simultaneously to screen the industrial solid hazardous waste contaminated soil. The largest contaminated soil enters the first conveyor belt 29, the medium-sized contaminated soil falls onto the second conveyor belt 30 through the screening holes of the first inclined plate 23, and the smallest contaminated soil falls onto the fourth synchronous belt 28 through the screening holes of the second inclined plate 24, thereby achieving fine screening of the industrial solid hazardous waste contaminated soil.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
