Description

Technical Field

[0001] This utility model relates to the field of soil pollution treatment technology, specifically a surface soil pollution reduction and carbon reduction treatment box. Background Technology

[0002] Soil pollutants can be broadly classified into two categories: inorganic pollutants and organic pollutants. When the soil contains too many harmful substances, exceeding its self-purification capacity, these harmful substances or their decomposition products will gradually accumulate in the soil and be indirectly absorbed by the human body, reaching a level that endangers human health; this is soil pollution.

[0003] A search revealed a patent document with publication number CN219899613U, which discloses a contaminated soil pollution reduction and carbon reduction treatment box. The box includes a treatment body and a wastewater collection tank. Load-bearing supports are fixedly installed at the bottom of the treatment body near the four corners. This invention allows for the crushing of contaminated soil in the feed hopper by starting a primary motor, ensuring thorough mixing and washing with the treatment liquid. A screw conveyor moves the contaminated soil, and a circulating water pump draws the pollution reduction and carbon reduction treatment agent from the wastewater collection tank through a treatment liquid connecting pipe to a spray pipe for spraying and discharge. This process also repairs the contaminated soil transported by the screw conveyor. Waste liquid is recycled through a drain hole in the waste liquid discharge hopper to the wastewater collection tank for reuse, reducing waste. This structure facilitates the transfer of contaminated soil, improving the efficiency of pollution reduction and carbon reduction treatment.

[0004] While the aforementioned existing technologies can conveniently treat contaminated soil and facilitate its transfer, they only involve crushing the surface contaminated soil. Although this refines the particle size, the crushed surface contaminated soil still suffers from uneven particle size. Larger particles may not fully penetrate during spraying, while finer surface contaminated soil dust may seep into the wastewater collection tank along with excess treatment agents, accelerating the accumulation of soil impurities within the tank. Therefore, a new surface soil pollution reduction and carbon reduction treatment box is proposed to optimize the aforementioned existing technologies. Utility Model Content

[0027] 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 protection scope of the present utility model.

[0028] Please see Figure 1In this embodiment of the utility model, a surface soil pollution reduction and carbon reduction treatment box includes a trough-shaped screw conveyor 1. The top surface of the trough-shaped screw conveyor 1 is open, and a discharge port is provided near the motor end. Support brackets 2 are fixedly connected to the four corners of the bottom surface of the trough-shaped screw conveyor 1. A contaminated soil feed hopper 3 is fixedly connected above the feed end of the trough-shaped screw conveyor 1. The top of the contaminated soil feed hopper 3 is open, and a crushing mechanism is installed on the top of the contaminated soil feed hopper 3. The interior of the contaminated soil feed hopper 3 has a staggered design from top to bottom. The hopper 3 is equipped with a first screen plate 4, a second screen plate 5, and a guide plate 6 at an incline. The contaminated soil feed hopper 3 has discharge ports 7 at the bottom edges of the first screen plate 4, the second screen plate 5, and the guide plate 6. A collection device can be installed on the outside of the discharge port 7 corresponding to the first screen plate 4 to collect the large pieces of surface contaminated soil that have been screened, and it can be crushed again. A baffle 8 is fixedly connected to the side wall of the contaminated soil feed hopper 3 corresponding to the outside of the discharge port 7 of the second screen plate 5. The baffle 8 is connected to the trough screw conveyor 1.

[0029] Below the crushing mechanism in the contaminated soil feed hopper 3, a first screen plate 4, a second screen plate 5, and a guide plate 6 are installed, which can screen out large particles of surface contaminated soil and dust in the surface contaminated soil, effectively ensuring the uniformity of surface contaminated soil particles entering the trough screw conveyor 1.

[0030] Please see Figure 2 The first screen plate 4 and the second screen plate 5 both slide through the contaminated soil feed hopper 3. One side of the first screen plate 4 and the second screen plate 5 are fixedly connected to a moving groove 9 by a connecting rod. A rotating disk 10 is provided below the moving groove 9. A moving pin 11 is fixedly connected to the eccentric part of the top surface of the rotating disk 10. The moving pin 11 is located in the moving groove 9 and is movably connected to the moving groove 9. The diameter of the moving pin 11 is adapted to the width of the moving groove 9. The rotating disk 10 is fixedly connected to the output end of the first motor 12. The first motor 12 is fixedly connected to the side wall of the contaminated soil feed hopper 3.

[0031] The first motor 12 drives the rotating disk 10 to rotate, and the rotating pin 11 pushes and pulls the rotating groove 9 through the circular motion, thereby causing the first screen plate 4 and the second screen plate 5 to reciprocate, increasing the screening effect.

[0032] Please see Figure 3 The crushing mechanism includes two matching crushing rollers 13, which are rotatably connected to the inside of the contaminated soil feed hopper 3. One end of each crushing roller 13 extends out of the contaminated soil feed hopper 3 and is fixedly connected to a gear 14. The gears 14 mesh with each other for transmission. A U-shaped frame 15 is fixedly connected to the contaminated soil feed hopper 3 and fastened to the outside of the gear 14. A second motor 16 is fixedly connected to the shaft end of one of the crushing rollers 13 on the U-shaped frame 15. The output end of the second motor 16 is fixedly connected to the shaft end of the corresponding crushing roller 13.

[0033] The second motor 16 drives the crushing roller 13 to rotate. The crushing roller 13 is linked by the gear 14, so that both crushing rollers 13 rotate. The rotating crushing roller 13 can crush the surface contaminated soil fed from the top of the contaminated soil hopper.

[0034] Please see Figure 4 A dust collection bin 17 is provided on the outside of the discharge port 7 corresponding to the guide plate 6 and is connected to it. The bottom drain port of the dust collection bin 17 is threadedly connected to a threaded end cap 18 that is compatible with it. The outer wall of the bottom drain port of the dust collection bin 17 is provided with external threads. An air outlet pipe 19 is fixedly connected through the side wall of the dust collection bin 17. An exhaust fan 20 is installed in the air outlet pipe 19. A dust filter cylinder 21 is fixedly connected to the end of the air outlet pipe 19 in the dust collection bin 17.

[0035] The bottom of the contaminated soil feed hopper 3 is sealed by the guide plate 6, and the exhaust fan 20 draws in the dust, which is then filtered by the dust filter cylinder 21. This effectively removes the dust generated by crushing the surface contaminated soil, reduces the amount of dust carried by the surface contaminated soil particles, and further improves the screening effect.

[0036] Please see Figure 1 The trough-type screw conveyor 1 is also fixedly connected to an isolation cover 22, which is fixedly connected to a baffle cover 8. A spray pipe 23 is fixedly connected inside the isolation cover 22, and spray nozzles are fixedly connected at equal intervals on the spray pipe 23.

[0037] A pump body 24 is fixedly installed on the top surface of the isolation cover 22. The trough-shaped screw conveyor 1 has evenly spaced leakage holes 25 below the spray pipe 23. The bottom surface of the trough-shaped screw conveyor 1 is fixedly connected to the leakage holes 25. A liquid collection tank 27 is provided below the liquid collection tank 26. A filter screen cylinder 28 that is compatible with it is placed in the top opening of the liquid collection tank 27. The top of the filter screen cylinder 28 has a hanging edge, which is hung on the edge of the top opening of the liquid collection tank 27. The filter screen cylinder 28 corresponds to the liquid collection tank 26. The liquid inlet end of the pump body 24 is fixedly connected to the liquid collection tank 27 through a pipe and is in communication with it. The liquid outlet end of the pump body 24 is fixedly connected to the spray pipe 23 through a pipe and is in communication with it.

[0038] The surface contaminated soil treatment solution in the chemical collection tank 27 is transported to the spray pipe 23 through the pump body 24, and sprayed through the nozzles, thereby spraying the surface contaminated soil particles conveyed by the trough screw conveyor 1 to treat them, thereby reducing pollution and carbon emissions.

[0039] The surface contaminated soil treatment solution in the solution collection tank 27 is transported to the spray pipe 23 through the pump body 24 and sprayed through the nozzle. During spraying, excess solution passes through the leakage hole 25, is collected by the collection bucket 26, drips into the filter screen cylinder 28 for filtration, and flows back into the solution collection tank 27, thus forming a recycling effect and achieving the effect of saving.

[0040] Please see Figure 1 Below the first screen plate 4, there is an inclined plate 29 with the same inclination direction. The top and sides of the inclined plate 29 are fixedly connected to the inner wall of the contaminated soil feed hopper 3, and the bottom edge of the inclined plate 29 corresponds to the upper part of the second screen plate 5.

[0041] The inclined plate 29 guides the surface contaminated soil particles screened by the first screen plate 4, preventing the surface contaminated soil from being directly discharged through the discharge port 7 of the second screen plate 5, which would affect the screening effect of the second screen plate 5.

[0042] The trough screw conveyor 1, the first motor 12, the second motor 16, the exhaust fan 20, and the pump body 24 are all electrically connected to an external power source and switch via wires.

[0043] The working principle of this utility model is as follows:

[0044] In operation, surface contaminated soil is fed into the contaminated soil feed hopper 3. The second motor 16 drives the crushing roller 13 to rotate. The crushing roller 13 is linked by gear 14, causing both rollers to rotate. The rotating rollers crush the surface contaminated soil fed into the feed hopper 3. The crushed surface contaminated soil particles fall onto the first screen plate 4 and are screened. Larger particles slide down the first screen plate 4 and are discharged through the corresponding outlet 7. Particles passing through the first screen plate 4 are guided by the inclined plate 29 and finally fall onto the second screen plate 5 for further screening. Dust falls onto the guide plate 6 and enters the dust collection bin 17 through the corresponding outlet 7. The screened surface contaminated soil particles enter the baffle hood 8 through the corresponding outlet 7 of the second screen plate 5 and then fall into the trough. The contaminated soil particles are conveyed within the screw conveyor 1. During conveying, the chemical solution in the chemical collection tank 27 is pumped by the pump body 24 to the spray pipe 23, where it is sprayed through the nozzles. This spraying process treats the contaminated soil particles conveyed by the screw conveyor 1, thereby reducing pollution and carbon emissions. Excess chemical solution during spraying passes through the drain hole 25, is collected by the collection hopper 26, drips into the filter screen cylinder 28 for filtration, and then flows back into the chemical collection tank 27, thus achieving a recycling effect and saving resources. The sprayed contaminated soil particles are then discharged from the outlet of the screw conveyor 1.

[0045] During the screening and filtration process of the first screen plate 4 and the second screen plate 5, the first motor 12 drives the rotating disk 10 to rotate. The rotating pin 11 pushes and pulls the rotating groove 9, thereby causing the first screen plate 4 and the second screen plate 5 to reciprocate, increasing the screening effect. The exhaust fan 20 draws in the dust, and the dust filter cylinder 21 filters the dust, thus sucking the dust into the contaminated soil feed hopper 3. This effectively removes the dust generated by the crushing of the surface contaminated soil, reduces the amount of dust carried by the surface contaminated soil particles, and further improves the screening effect.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
