Description

Technical Field

[0002] With the acceleration of the industrialization and urbanization processes, the problem of soil pollution by solid wastes such as waste residues and large particles is becoming increasingly serious. Soil remediation refers to using physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances.

[0003] Currently, during the process of treating solid waste pollution in soil, a remediation agent is usually added to the soil. Due to the easy caking of the soil, it is difficult for the remediation agent to penetrate into the interior of the soil for remediation. Moreover, the traditional method of centrally spraying the remediation agent results in uneven mixing of the soil and the remediation agent, leading to insufficient reaction. Further, when decontaminating the soil and removing solid wastes, multiple independent treatment devices are usually required for turnover. During the turnover process, it pollutes the outside world and affects the efficiency of soil treatment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The present invention drives the inner cylinder inside to rotate synchronously through the outer cylinder. During the rotation of the inner cylinder, the internal forward spiral blades are driven to rotate together. The atomized water vapor sprayed by the atomizing nozzle is sprinkled onto the soil in the inner cylinder. During the rotation, the forward spiral blades can gradually transport the soil to the right. Part of the soil will adhere to the inner wall of the inner cylinder. As the inner cylinder rotates, the soil will roll down under the action of gravity. Therefore, while the forward spiral blades transport the soil to the right, the soil is automatically turned over and thrown. The atomizing nozzle is cooperated to spray atomized water vapor onto the moving soil, so that the soil and the repair agent are fully in contact, thereby improving the reaction effect. When the forward spiral blades transport the soil to the rightmost end of the inner cylinder, the soil will fall from the drop hole on one side of the bottom of the inner cylinder, and then the soil will be transferred between the outer cylinder and the inner cylinder. During the rotation of the reverse spiral blades driven by the outer cylinder, the soil can be transported. Because the spiral lines of the forward spiral blades and the reverse spiral blades are in opposite directions, the soil falls on the outer cylinder. The soil between the cylinder and the inner cylinder will be transported to the left and work with the electric heating rod to thermally degas the soil and accelerate the evaporation rate of water vapor. When the reverse spiral blade transports the soil to the leakage hole in the outer cylinder, the treated soil will fall from the leakage hole into the hopper at the bottom of the fixed cylinder, and the large particles of solid waste mixed in the soil will be isolated between the outer cylinder and the inner cylinder by the leakage hole. As the reverse spiral blade continues to rotate, it transports the large particles of solid waste to the waste discharge hole at the bottom of the outer cylinder, so that the large particles of solid waste are discharged through the waste discharge hole and the waste discharge valve, and the isolation ring can separate the large particles of solid waste from the treated soil to facilitate the classification and collection of the two. When the soil is decontaminated and the solid waste is removed, the treatment process is integrated into a single device, and there is no need to frequently turn over the soil to improve work efficiency. Moreover, the treatment process is isolated from the outside world and will not cause pollution to the outside world.

[0016] When the driven gear is driven to rotate by the active gear, the driven gear drives two cams to rotate through the connecting shaft, so that the cam will squeeze the blocking rod. When the highest point of the cam rotates to the uppermost position, the cam pushes the slide frame upward through the blocking rod, so that the slide frame can squeeze the three springs above, and the slide frame is limited by the groove on the top of the fixed cylinder to improve the stability of the slide frame moving up and down. During this process, the slide frame drives the four knocking wheels at the bottom to move away from the top of the outer cylinder. When the highest point of the cam is separated from the blocking rod during the rotation of the cam, the slide frame is supported by the elastic force of the three springs, so that the slide frame drives the knocking wheels at the four corners of the bottom to move downward quickly, so that the knocking wheels can knock on the outer cylinder, causing the outer cylinder to vibrate and shake off the soil at the leakage hole. During the rotation of the outer cylinder, the knocking wheel cooperates with it to continuously knock it, so as to achieve the purpose of automatic clearing and prevent the leakage hole from being blocked by soil and large particles of solid waste.

[0017] In the present invention, the soil to be processed is added into the interior of the conveying cylinder through the feeding pipe. The motor is controlled to operate. The output shaft of the motor drives the rotating shaft to rotate through the driving gear, and the rotating shaft drives the spiral guiding piece to rotate. During the rotation process, the spiral guiding piece conveys the soil to the left. At the same time, the spiral guiding piece can crush the agglomerated soil and disperse it, preliminarily separating the soil from the solid waste and making the soil more fluffy, which is beneficial to subsequent reprocessing. As the spiral guiding piece continues to rotate, the soil is sent to the leftmost end of the conveying cylinder, and the soil will enter the inner cylinder through the feeding pipe and the rotary joint. Since the bottom end of the feeding pipe is connected to the outer cylinder through the rotary joint, the feeding pipe in the middle does not rotate during the rotation of the outer cylinder, thus ensuring the continuity of feeding.

As the inner cylinder 3004 rotates, the soil will roll down due to gravity. Therefore, while the forward spiral blades 3007 transport the soil to the right, the soil will be automatically turned over, so that the soil is fully in contact with the repair agent sprayed by the application component 4, thereby improving the reaction effect.

[0025] As a further solution of the present invention, the drug application component 4 includes a pump body 4001, the water outlet end of the pump body 4001 is connected to a central tube 4002, the central tube 4002 is L-shaped and the lateral part thereof passes through the fixed tube 1 through a sleeve and is located at the center of the inner tube 3004, and a plurality of atomizing nozzles 4003 are installed at equal intervals outside the lateral part of the central tube 4002; During operation, the inner cylinder 3004 will drive the internal forward spiral blades 3007 to rotate during the rotation process, and at the same time control the operation of the pump body 4001.

[0026] As a further solution of the present invention, the extrusion assembly 7 includes a driven gear 7001, the driven gear 7001 is meshed and connected with the toothed ring 5, a connecting shaft 7002 is fixedly connected to the side of the driven gear 7001 close to the fixed cylinder 1, and both sides of the outer wall of the connecting shaft 7002 are mounted on the top of the inner wall of the fixed cylinder 1 through shaft sleeves.

[0027] As a further solution of the present invention, the knocking assembly 8 includes a sliding frame 8001, the sliding frame 8001 is slidably connected in the groove 6. When the highest point of the cam 7003 rotates to the uppermost position, the cam 7003 pushes the sliding frame 8001 upward through the stop lever 8003, so that the sliding frame 8001 can squeeze the three springs 8004 above. The groove 6 at the top of the fixed cylinder 1 limits the sliding frame 8001 to improve the stability of the up and down movement of the sliding frame 8001; Knocking wheels 8002 are respectively installed at the four corners of the bottom of the sliding frame 8001, the bottoms of the four knocking wheels 8002 are lapped with the outer wall of the separation processing assembly 3, three springs 8004 are fixedly connected to the top of the sliding frame 8001 at equal intervals, the top ends of the springs 8004 are fixed to the top of the inner wall of the groove 6, and a stop lever 8003 is fixedly connected to the top of the inner wall of the sliding frame 8001, and the stop lever 8003 is lapped with the lowest points of the two cams 7003 below; During operation, the sliding frame 8001 drives the four knocking wheels 8002 at the bottom away from the top of the outer cylinder 3001. When the highest point of the cam 7003 breaks away from the stop lever 8003 during the rotation process, the sliding frame 8001 is supported by the elastic force of the three springs 8004, so that the sliding frame 8001 drives the knocking wheels 8002 at the four corners of the bottom to quickly move downward, so that the knocking wheels 8002 can knock the outer cylinder 3001, causing the outer cylinder 3001 to vibrate and shake off the soil at the leakage holes 3002. During the rotation of the outer cylinder 3001, it cooperates with the knocking wheels 8002 to continuously knock it, achieving the purpose of automatically clearing the blockage of the leakage holes 3002.

[0028] As a further solution of the present invention, the material guiding assembly 15 includes a conveying cylinder 151. The bottom of the conveying cylinder 151 is fixed on the fixed cylinder 1. On both sides of the inner wall of the conveying cylinder 151, a rotating shaft 152 is rotatably connected through a bushing.

The rotary joint 158 is installed through one side of the separation and treatment assembly 3; During operation, when the soil is sent to the leftmost end inside the conveying cylinder 151, the soil will enter the inner cylinder 3004 through the feed pipe 157 and the rotary joint 158. Since the bottom end of the feed pipe 157 is connected to the outer cylinder 3001 through the rotary joint 158, the feed pipe 157 in the middle does not rotate during the rotation of the outer cylinder 3001.

[0029] As a further solution of the present invention, on both sides of the inner wall of the fixed cylinder 1, isolation rings 9 are respectively fixedly connected. The inner walls of the two isolation rings 9 are lapped with the outer wall of the outer cylinder 3001. The isolation rings 9 can separate large particle solid waste from the treated soil to facilitate the classified collection of the two; On both sides of the bottom of the fixed cylinder 1, a waste discharge valve 13 and an exhaust valve pipe 14 are respectively installed. The waste discharge valve 13 is located below the waste discharge hole 3003. A hopper 11 is provided between the waste discharge valve 13 and the exhaust valve pipe 14. The hopper 11 is communicated with the bottom of the fixed cylinder 1. At the bottom end of the hopper 11, a discharge valve 12 is installed. At the bottom of the fixed cylinder 1, support legs 16 are fixed. The bottom of the medicine application assembly 4 is fixedly installed on one side of the bottom of the support legs 16; During operation, the electric heating rod 10 is controlled to work, so that heat is transferred to the inner cylinder 3004 through the outer cylinder 3001. The inner cylinder 3004 transfers the heat to the internal soil for thermal desorption, accelerating the drying rate of the soil and preventing caking after contacting the sprayed atomized water vapor. During the process of applying medicine to the soil and thermal desorption, some harmful gases will be released. The exhaust valve pipe 14 is connected to an external purification device, so that the harmful gases inside the fixed cylinder 1 are discharged through the exhaust valve pipe 14 on one side of the bottom of the fixed cylinder 1, accelerating the discharge rate of the internal gas and preventing secondary pollution of the soil.

[0030] Working principle of the present invention: During the process of treating solid waste pollution in the soil, the soil to be treated is added into the inside of the conveying cylinder 151 through the feeding pipe 155. The motor 154 is controlled to work. The output shaft of the motor 154 drives the rotating shaft 152 to rotate through the driving gear 153. The rotating shaft 152 drives the spiral guide vane 156 to rotate. The spiral guide vane 156 conveys the soil to the left during rotation. At the same time, the spiral guide vane 156 can crush and disperse the caked soil, initially separating the soil from the solid waste, making the soil more fluffy and conducive to subsequent reprocessing. As the spiral guide vane 156 continues to rotate, the soil is sent to the leftmost end inside the conveying cylinder 151, and the soil will enter the inner cylinder 3004 through the feeding pipe 157 and the rotary joint 158. Since the bottom end of the feeding pipe 157 is connected to the outer cylinder 3001 through the rotary joint 158, the feeding pipe 157 in the middle does not rotate during the rotation of the outer cylinder 3001; When the soil enters the inner cylinder 3004, it will fall to the bottom inside the inner cylinder 3004 under the action of its own gravity. Since the driven gear 7001 is meshed with the driving gear 153 and the gear ring 5, the driving gear 153 will drive the gear ring 5 to rotate through the driven gear 7001. The gear ring 5 drives the outer cylinder 3001 to rotate, and the outer cylinder 3001 drives the inner cylinder 3004 inside to rotate synchronously. The inner cylinder 3004 drives the internal positive spiral blade 3007 to rotate together during rotation. At the same time, the pump body 4001 is controlled to work. The pump body 4001 extracts the repair agent from the outside, so that the repair agent passes through the central pipe 4002 and is sprayed out from the atomizing nozzle 4003. The atomized water vapor sprayed out from the atomizing nozzle 4003 will be sprinkled on the soil in the inner cylinder 3004. The positive spiral blade 3007 can gradually convey the soil to the right during rotation. Some soil will adhere to the inner wall of the inner cylinder 3004. As the inner cylinder 3004 rotates, the soil will roll down under the action of gravity. Therefore, while the positive spiral blade 3007 conveys the soil to the right, it automatically turns over the soil, and cooperates with the atomizing nozzle 4003 to spray the atomized water vapor on the moving soil, so that the soil and the repair agent are fully contacted, improving the reaction effect; In the process of the forward spiral blade 3007 conveying the soil, the electric heating rods 10 on the front and rear sides of the inner wall of the fixed cylinder 1 work, and the heat is transferred to the inner cylinder 3004 through the outer cylinder 3001. The inner cylinder 3004 transfers the heat to the internal soil for thermal desorption, thereby accelerating the drying speed of the soil and preventing agglomeration after contact with the sprayed atomized water vapor. Some harmful gases will be released during the application of pesticides to the soil and the thermal desorption process. The exhaust valve pipe 14 is connected to the external purification equipment, so that the harmful gases inside the fixed cylinder 1 are discharged through the exhaust valve pipe 14 on one side of the bottom of the fixed cylinder 1, thereby accelerating the discharge speed of the internal gas and preventing secondary pollution of the soil. When the forward spiral blade 3007 transports the soil to the rightmost end of the inner cylinder 3004, the soil will fall from the drop hole 3006 on one side of the bottom of the inner cylinder 3004, and then the soil will be transferred between the outer cylinder 3001 and the inner cylinder 3004. The outer cylinder 3001 drives the reverse spiral blade 3005 to rotate to transport the soil. Because the spiral lines of the forward spiral blade 3007 and the reverse spiral blade 3005 are in opposite directions, the soil falling between the outer cylinder 3001 and the inner cylinder 3004 will be transported to the left, and work with the electric heating rod 10 to heat the soil and accelerate the evaporation rate of water vapor. When the reverse spiral blade 3 When the soil is transported to the leakage hole 3002 in the outer cylinder 3001 by the reverse spiral blade 3005, the processed soil will fall from the leakage hole 3002 into the hopper 11 at the bottom of the fixed cylinder 1, and the large particles of solid waste mixed in the soil will be isolated between the outer cylinder 3001 and the inner cylinder 3004 by the leakage hole 3002. As the reverse spiral blade 3005 continues to rotate, it will transport the large particles of solid waste to the waste discharge hole 3003 at the bottom of the outer cylinder 3001, so that the large particles of solid waste are discharged through the waste discharge hole 3003 and the waste discharge valve 13, and the isolation ring 9 can separate the large particles of solid waste from the processed soil, so as to facilitate the classification and collection of the two. When the driving gear 153 drives the driven gear 7001 to rotate, the driven gear 7001 drives the two cams 7003 to rotate through the connecting shaft 7002, so that the cams 7003 will squeeze the blocking rod 8003. When the highest point of the cam 7003 rotates to the top, the cam 7003 pushes the slide frame 8001 upward through the blocking rod 8003, so that the slide frame 8001 can squeeze the three springs 8004 above, and the slide frame 8001 is limited by the groove 6 at the top of the fixed cylinder 1, so as to improve the stability of the slide frame 8001 moving up and down. In this process, the slide frame 8001 drives the four knocking springs at the bottom to move upward and downward. The striking wheel 8002 is away from the top of the outer cylinder 3001. When the highest point of the cam 7003 is separated from the blocking rod 8003 during the rotation, the sliding frame 8001 is supported by the elastic force of the three springs 8004, so that the sliding frame 8001 drives the striking wheels 8002 at the four corners of the bottom to move downward rapidly, so that the striking wheel 8002 can strike the outer cylinder 3001, causing the outer cylinder 3001 to vibrate and shake off the soil at the leakage hole 3002. During the rotation of the outer cylinder 3001, the striking wheel 8002 continuously strikes it to prevent the leakage hole 3002 from being blocked by soil and large particles of solid waste.
