Description

TECHNICAL FIELD

[0001] The present application relates to the field of soil treatment, in particular to a soil detection pollutant separation device. BACKGROUND

[0002] The current soil pollutant separation technology has many defects in practical application, and it is difficult to meet the needs of efficient and accurate separation. First, in the soil crushing and stirring link, the existing equipment mostly uses single type stirring parts, and the stirring parts are fixed in position, which cannot adjust the stirring range and intensity according to the actual state of the soil, resulting in uneven soil crushing, and part of the blocky soil cannot be fully contacted with the blending liquid and water, affecting the subsequent pollutant decomposition and separation effect. For the soil containing more hard impurities, the fixed stirring parts are prone to serious wear, which shortens the service life of the equipment and increases the maintenance cost.

[0003] Secondly, in the supply of blending liquid and water, the liquid supply system of the existing equipment is mostly designed with fixed flow, which cannot flexibly adjust the liquid supply rate according to the amount of soil to be treated, the concentration of pollutants and other parameters. When the amount of soil is large or the concentration of pollutants is high, insufficient liquid supply will lead to incomplete decomposition of pollutants; while the amount of soil is small or the concentration of pollutants is low, excessive liquid supply will cause waste of resources and increase the burden of subsequent dehydration treatment.

[0004] Thirdly, the upper end of the inner wall of the heating cylinder of the existing heating separation equipment is prone to organic matter condensation. The volatilized organic matter contacts the inner wall of the heating cylinder and cannot be discharged in time, condenses into liquid in the low temperature area and adheres to the wall surface. Long-term accumulation will affect the heating efficiency of the heating cylinder, and the condensed organic matter may be mixed into the soil again, leading to incomplete separation. In terms of power transmission and component protection, the power transmission mechanism of the existing equipment mostly adopts mechanical hard connection mode, which is noisy and severely worn during transmission, and when overload occurs, the transmission components are prone to damage. For the elastic structure in the stirring part, there is a lack of effective protection measures, and when it contacts with hard soil or impurities, the elastic component is prone to deformation and fracture, affecting the stirring effect.

[0005] Therefore, it is necessary to design a soil detection pollutant separation device to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0042] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0043] REFERENCE Figures 1 to 9 A soil detection pollutant separation device, comprising:

[0044] The hot cylinder 2 is arranged above the dehydration machine 1, the top cover 3 of the hot cylinder 2 is communicated with the air pipe 9, the middle part of the hot cylinder 2 is provided with the feed inlet 4, and the lower end of the hot cylinder 2 is provided with the filter screen 10, and the upper end of the filter screen 10 is slidably provided with the sliding plate 11;

[0045] The chopper 22 is arranged in the hot cylinder 2, the chopper 22 comprises the middle pipe 48 rotatably connected with the filter screen 10, the middle pipe 48 is internally formed with the liquid cavity 49, the middle pipe 48 is externally sleeved with the sleeve 50, and the lower end of the top cover 3 is rotatably provided with the scraper 53 fixedly connected with the middle pipe 48;

[0046] The main cutter 23 is fixedly connected to the lower end of the middle pipe 48, the secondary cutter 35 is fixedly connected to the sleeve 50 above the main cutter 23, the rigid paddles 24 are arranged at equal angles on one side of the main cutter 23 close to the secondary cutter 35, and the elastic paddles 36 are arranged at equal angles on the upper end of the secondary cutter 35 and connected with the sleeve 50;

[0047] The nozzle 8 is arranged at equal angles in the circumferential direction on one side of the secondary cutter 35 close to the rigid paddles 24 and communicated with the liquid cavity 49, and the spray head 21 is arranged on one side of the hot cylinder 2.

[0048] When the device is in operation, the operator puts the soil to be detected into the hot cylinder 2 from the feeding port 4, then injects the mixed liquid into the interior of the hot cylinder 2 through the spray head 21, and then injects clean water into the interior of the hot cylinder 2 through the nozzle 8. In this process, the crusher 22 is started and drives the main cutter 23 and the auxiliary cutter 35 to rotate. When the middle pipe 48 rotates, the main cutter 23 and the auxiliary cutter 35 crush the soil, and the rigid paddle 24 and the elastic paddle 36 stir the soil. In the stirring process, the hot cylinder 2 heats the materials in its interior. The heated steam overflows upward through the air pipe 9. The operator collects the exhaust gas from the upper end of the air pipe 9. When the middle pipe 48 rotates, the scraper 53 also scrapes the top end in the interior of the hot cylinder 2 to prevent the steam from condensing on the top end in the interior of the hot cylinder 2 after pre-cooling.

[0049] In addition, in the above process, the sleeve pipe 50 also moves along the axis direction of the middle pipe 48. When the sleeve pipe 50 moves, the auxiliary cutter 35 and the elastic paddle 36 also move until the soil is stirred into slurry. Then, the sliding plate 11 moves to make the filter screen 10 and the lower end of the hot cylinder 2 abut. After abutting, the slurry flows into the dehydrator 1 through the filter screen 10, and the solid pollutants in the soil are intercepted by the filter screen 10 so that the operator can clean them later.

[0050] Finally, the soil treated by the dehydrator 1 is recovered after dehydration.

[0051] In order to provide sufficient clean water to the hot cylinder 2, the following features are further provided:

[0052] As shown in Figure 2 , the side of the hot cylinder 2 is provided with a support 5. The upper end of the support 5 is provided with a water tank 6. The upper end of the water tank 6 is provided with a water pipe 7. One end of the water pipe 7 communicates with the water tank 6, and the other end is rotatably connected to the upper end of the middle pipe 48.

[0053] When the support 5 is installed, the operator needs to ensure that the distance between the support 5 and the hot cylinder 2 meets the placement requirements of the water tank 6. The bottom of the support 5 needs to be horizontally fixed to the ground to avoid the water tank 6 from shaking due to the inclination of the support 5. The water tank 6 stably delivers clean water to the liquid cavity 49 in the middle pipe 48 through the water pipe 7 to continuously supply water to the nozzle 8.

[0054] In order to provide the mixed liquid for decomposing organic pollutants into the interior of the hot cylinder 2, the following features are further provided:

[0055] As shown in Figure 2 and Figure 6 , the side of the support 5 is provided with a liquid cylinder 19. The liquid cylinder 19 communicates with the spray head 21 through a liquid pipe 20.

[0056] The operator can change the injection rate of the mixed liquid according to the amount of the soil to be treated and the concentration of the pollutants, and the mixed liquid in the liquid cylinder 19 is injected through the liquid pipe 20 and the spray head 21, which ensures that the mixed liquid fully reacts with the soil to decompose the organic pollutants.

[0057] In order to drive the sliding plate 11 to move, and then realize that the sliding plate 11 blocks the filter screen 10 during the reaction, and avoids the filter screen 10 after the reaction, the following features are further provided:

[0058] As shown in Figure 1 , Figure 3 and Figure 4 , two supports 17 are arranged at the upper end of the dewatering machine 1, and the filter screen 10 is fixedly connected with the two supports 17. Each support 17 is slidably arranged with two pneumatic sliding tables 18 on the side close to the hot cylinder 2, and the two sides of the sliding plate 11 are fixedly connected with the pneumatic sliding tables 18.

[0059] One end of the sliding plate 11 is provided with an avoiding hole 12, and a soft rubber cover 13 is fixedly connected with the upper end of the sliding plate 11 and movably connected with the lower end of the hot cylinder 2.

[0060] When the sliding plate 11 is driven to move, the two pneumatic sliding tables 18 drive the sliding plate 11 to move, and then realize the butt joint and dislocation of the avoiding hole 12 and the filter screen 10. In this process, the soft rubber cover 13 is made of wear-resistant and high-temperature-resistant silica gel material, and its size matches the opening at the lower end of the hot cylinder 2. When the sliding plate 11 blocks the filter screen 10, the soft rubber cover 13 can tightly fit the lower end of the hot cylinder 2 to prevent soil materials or slurry from leaking from the gap; when the avoiding hole 12 is aligned with the filter screen 10 by moving the sliding plate 11, the soft rubber cover 13 moves synchronously with the sliding plate 11, without affecting the normal discharge of the slurry. The avoiding hole 12 is arranged at a position corresponding to the edge of the filter screen 10 to avoid collision between the sliding plate 11 and the filter screen 10 or the support 17 during movement.

[0061] In order to drive the sleeve 50 to move reciprocally in the vertical direction, and then drive the secondary cutter 35 and the elastic paddle 36 to move in the vertical direction, the following features are further provided:

[0062] As shown in Figure 5 , the upper end of the top cover 3 is fixedly connected with two reciprocating air cylinders 14, and the two reciprocating air cylinders 14 are arranged on the two sides of the middle pipe 48. A clamping seat 15 is arranged above the top cover 3, and the two ends of the clamping seat 15 are fixedly connected with the output ends of the two reciprocating air cylinders 14.

[0063] The middle part of the clamping seat 15 is rotatably connected with a limiting sleeve 16, the limiting sleeve 16 is fixedly connected with the upper end of the sleeve 50, and the limiting sleeve 16 is slidably connected with the middle pipe 48.

[0064] Before the reciprocating cylinder 14 is installed, the operator needs to debug the stroke of the output end to ensure that the extension distance of the output end can meet the movement requirements of the sub-knife 35 and the elastic paddle 36 in the hot cylinder 2, so as to realize the crushing and stirring of different height soils. The synchronous operation of the two reciprocating cylinders 14 drives the clamping seat 15 to move, and the clamping seat 15 moves to drive the sleeve 50 to move, thereby realizing the movement of the sub-knife 35 and the elastic paddle 36 (for reference Figure 6 ).

[0065] In order to drive the middle pipe 48 to rotate, the following features are further provided:

[0066] As shown in Figure 3 and Figure 4 , the hot cylinder 2 is provided with a main motor 45 beside it, the output end of the main motor 45 is coaxially fixedly connected with a main bevel gear 46, the main bevel gear 46 is provided with a sub-bevel gear 47 beside it, the sub-bevel gear 47 is coaxially fixedly connected with a magnetic shaft 54, and the magnetic shaft 54 is coaxially driven by magnetic force with the lower end of the middle pipe 48;

[0067] The lower end of the filter screen 10 is provided with a guard plate 52, the two ends of the guard plate 52 are fixedly connected with the two supports 17 respectively, and the side of the guard plate 52 close to the filter screen 10 is formed with a curved surface.

[0068] When the main motor 45 starts, the main motor 45 will drive the sub-bevel gear 47 to rotate through the main bevel gear 46, and the sub-bevel gear 47 will drive the middle pipe 48 to rotate through the magnetic shaft 54. The magnetic transmission between the magnetic shaft 54 and the lower end of the middle pipe 48 adopts strong magnetic material to ensure the stability of the transmission torque between them, so as to avoid the rotation lag or stop of the middle pipe 48 due to insufficient magnetic force. The curved surface design of the guard plate 52 ensures that when the mud flows into the dehydrator 1 through the filter screen 10, the curved surface can guide the mud to prevent the mud from accumulating below the filter screen 10; at the same time, the guard plate 52 can block the impurities generated during the operation of the dehydrator 1 from splashing to the filter screen 10, thereby protecting the filtering effect of the filter screen 10.

[0069] In order to supplement the specific structure of the rigid paddle 24, the following features are further provided:

[0070] As shown in Figure 6 , Figure 8 and Figure 9 , the rigid paddle 24 comprises a middle frame 25 arranged in a horizontal state, one end of the middle frame 25 close to the middle pipe 48 is rotatably provided with a pipe seat 26, the pipe seat 26 is fixedly connected with the middle pipe 48, the middle frame 25 is coaxially rotatably connected with the pipe seat 26, and two vortex rods 27 are coaxially fixedly connected outside the middle frame 25.

[0071] When the two vortex rods 27 rotate with the middle frame 25, the two vortex rods 27 can crush and turn the soil from different directions, improving the crushing efficiency and uniformity of the soil. The rod body of the vortex rod 27 is made of high-strength alloy steel, and the surface is treated with wear-resistant coating to enhance its wear resistance and resist the wear of hard impurities in the soil.

[0072] In order to rotate the middle tube 48, the middle tube 48 can drive the two vortex rods 27 to rotate along the axis of the middle frame 25 when the middle tube 48 rotates, and the following features are also provided:

[0073] As shown in Figure 6 , Figure 8 and Figure 9 , a bracket 28 is arranged below the middle frame 25, and the bracket 28 is fixedly connected with the hot cylinder 2. The upper end of the bracket 28 is fixedly connected with a tray 29, and the tray 29 is coaxially fixedly connected with a gear ring 30. The gear ring 30 is rotationally connected with the middle tube 48.

[0074] The tube seat 26 is rotationally connected with a second bevel gear 33, and the second bevel gear 33 is coaxially fixedly connected with the middle frame 25. A first bevel gear 32 is arranged beside the second bevel gear 33 and rotationally connected with the tube seat 26. The first bevel gear 32 is meshed with the second bevel gear 33. The lower end of the first bevel gear 32 is coaxially fixedly connected with a gear 34, which is rotationally connected with the tube seat 26 and meshed with the gear ring 30. The upper end of the tray 29 is rotationally connected with a stand 31, and the stand 31 is fixedly connected with the tube seat 26.

[0075] When the middle tube 48 rotates, the middle tube 48 will drive the middle frame 25 to rotate along the upper end of the tray 29. When the tube seat 26 rotates, the gear 34 at the lower end of the tube seat 26 will mesh with the gear ring 30. At this time, the gear 34 will rotate, and the rotated gear 34 will drive the second bevel gear 33 to rotate through the first bevel gear 32. The second bevel gear 33 will drive the two vortex rods 27 to rotate through the middle frame 25.

[0076] In order to supplement the specific structure of the elastic paddle 36, the following features are also provided:

[0077] As shown in Figure 6 and Figure 7 , the elastic paddle 36 includes a swing roller 37 fixedly connected with a sleeve 50. The swing roller 37 is fixedly connected with sleeve 38 at equal intervals on the upper end. The sleeve 38 is coaxially provided with a spring 40. The lower end of the spring 40 is fixedly connected with the sleeve 38, and the upper end is fixedly connected with a sliding disc 41.

[0078] The upper end of the sleeve 38 is fixedly connected with a cover 39. The upper end of the sliding disc 41 is coaxially fixedly connected with a plug rod 42. The plug rod 42 is slidingly connected with the cover 39. The upper end of the plug rod 42 is fixedly connected with a sliding cylinder 43 slidingly connected with the sleeve 50.

[0079] When the elastic paddle 36 rotates with the sub-blade 35, the swing roller 37 drives the sleeve 38, the spring 40, the sliding disc 41, the insertion rod 42 and the sliding cylinder 43 to rotate synchronously, so as to stir the soil in the hot cylinder 2. When encountering blocky soil or hard impurities, the sliding cylinder 43 is extruded to push the insertion rod 42 to move downward, the insertion rod 42 drives the sliding disc 41 to compress the spring 40, the elastic force generated by the spring 40 can buffer the impact force received by the sliding cylinder 43, so as to avoid damage of components due to hard collision; after passing the impurities, the spring 40 restores to the original state to push the sliding disc 41, the insertion rod 42 and the sliding cylinder 43 to reset, so as to ensure that the sliding cylinder 43 always contacts with the soil to continuously perform the stirring operation. At the same time, the buckle cover 39 can limit the movement range of the sliding disc 41 to prevent the sliding disc 41 from being detached from the sleeve 38, and the sliding cooperation between the insertion rod 42 and the buckle cover 39 ensures the smoothness of the upward and downward movement of the sliding cylinder 43, so as to ensure that the elastic paddle 36 can adapt to the soil in different states to realize uniform stirring.

[0080] In order to protect the upper end of the sliding cylinder 43, the following features are further provided:

[0081] As shown in Figure 7 The upper end of the sliding cylinder 43 is fixedly connected with a spherical soft rubber 44.

[0082] The spherical soft rubber 44 is made of rubber material with good elasticity, and the smooth surface thereof can reduce the frictional resistance with the soil to improve the stirring efficiency; at the same time, when the spherical soft rubber 44 contacts with the soil, it can produce a certain extrusion and turning effect on the soil to assist the elastic paddle 36 to scatter the soil, so as to further improve the mixing uniformity of the soil, the blending liquid and the water, and create favorable conditions for subsequent decomposition of pollutants.

[0083] The detailed working principle of the device is as follows:

[0084] Before the device is started, the operator first pours the soil from the feed inlet 4 into the hot cylinder 2, and after the device is started, the water in the water tank 6 is delivered to the liquid cavity 49 inside the middle pipe 48 through the water pipe 7, and then sprayed out through the nozzles 8 arranged in a circumferential array to be uniformly sprayed in the circumferential direction to the soil in the hot cylinder 2; at the same time, the blending liquid in the liquid cylinder 19 is delivered to the spray head 21 at the upper part of the hot cylinder 2 through the liquid pipe 20, and the operator adjusts the spraying rate of the blending liquid according to the amount of the soil to be treated and the concentration of the organic pollutants, so as to ensure that the blending liquid can fully contact with the soil and react to decompose the organic pollutants.

[0085] When the soil is stirred and mixed, the main motor 45 starts to drive the middle tube 48 to rotate. The middle tube 48 drives the sleeve 50 to rotate synchronously, and then the main knife 23 fixedly connected with the middle tube 48 and the auxiliary knife 35 fixedly connected with the sleeve 50 rotate together to preliminarily stir and mix the soil. At the same time, the two reciprocating air cylinders 14 on the upper end of the top cover 3 operate synchronously, the output end drives the clamping seat 15 to move up and down, the limiting sleeve 16 rotatably connected to the middle part of the clamping seat 15 moves with the clamping seat 15, thereby driving the sleeve 50 to vertically reciprocate along the axis direction of the middle tube 48, the sleeve 50 drives the auxiliary knife 35 and the elastic paddle 36 to move up and down, and cooperates with the fixed rotation of the main knife 23 to form a three-dimensional stirring and mixing range.

[0086] When the middle tube 48 rotates, the middle frame 25 of the rigid paddle 24 is revolved around the middle tube 48 under the drive of the tube seat 26, and the gear 34 at the lower end of the tube seat 26 meshes with the fixed gear ring 30 on the tray 29 to rotate, the gear 34 drives the first bevel gear 32 to drive the second bevel gear 33, the second bevel gear 33 drives the middle frame 25 to rotate around its axis, so that the two vortex rods 27 outside the middle frame 25 rotate while revolving, and the soil is strongly stirred from different directions. The high-strength alloy material and the surface wear-resistant coating of the vortex rod 27 can cope with hard impurities in the soil and avoid wear.

[0087] The elastic paddle 36 at the upper end of the auxiliary knife 35 rotates with the auxiliary knife 35 to elastically stir the soil. When encountering blocky soil or hard impurities, the sliding cylinder 43 is extruded to drive the inserting rod 42 to move downward, the sliding disc 41 compresses the spring 40 to buffer the impact force, and after passing the impurities, the spring 40 is reset, so that the sliding cylinder 43 is always in contact with the soil, the stirring continuity is maintained, the mixing uniformity of the soil, clean water and blending liquid is improved, and the soil is stirred into mud until the soil is stirred into mud.

[0088] After the soil is formed into mud, the heating cylinder 2 starts the heating function to continuously heat the mud inside, so that the temperature of the mud is increased. The volatile organic pollutants in the mud are converted into steam after being heated, overflow upward along the gas pipe 9 connected with the top cover 3 of the heating cylinder 2, and the steam is collected by the waste gas collecting device on the upper end of the gas pipe 9, and then harmless treatment is performed. During the heating process, the scraping plate 53 fixedly connected with the top cover 3 at the lower end of the middle tube 48 rotates synchronously with the middle tube 48, the scraping plate 53 tightly abuts against the inner top end of the heating cylinder 2, and the organic matter condensed on the inner wall of the top end after the steam meets the cold is scraped in time, so as to prevent the organic matter from being accumulated to affect the heating efficiency of the heating cylinder 2, or the condensed organic matter falls into the mud again to cause secondary pollution in the subsequent separation, and the complete separation of the organic pollutants is ensured.

[0089] When the heating and coagulation removal process is completed, the pneumatic sliding table 18 drives the sliding plate 11 to slide along the support 17. During the movement of the sliding plate 11, the soft rubber cover 13 at the upper end of the sliding plate 11 is always in dynamic sealing connection with the lower end of the hot cylinder 2, so as to avoid leakage of the slurry, until the avoiding hole 12 on the sliding plate 11 is aligned with the filter screen 10 at the lower end of the hot cylinder 2, so as to realize the butt joint of the filter screen 10 and the lower end of the hot cylinder 2. At this time, the slurry flows into the dewatering machine 1 through the filter screen 10 under the action of gravity, and the filter screen 10 intercepts the solid pollutants in the slurry, so as to prevent the solid pollutants from entering the dewatering machine 1 and affecting the dewatering effect. After the slurry flows into the dewatering machine 1 through the filter screen 10, the dewatering machine 1 is started, and the slurry is dewatered by extrusion, centrifugation and other ways, so as to remove the water in the slurry, and make the soil form solid soil blocks.
