Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of soil pollutant remediation, and particularly relates to a device for efficiently degrading high-concentration petroleum hydrocarbon in soil. BACKGROUND

[0002] Petroleum hydrocarbon originally refers to a mixture containing carbon and hydrogen compounds found in crude oil, and is one of the organic pollutants widely existing in the environment. In the process of oil exploitation, processing and utilization, more and more oil may enter the soil environment and the ocean, thereby causing pollution and damage to the soil environment and the ocean water quality.

[0003] The degradation technologies for petroleum hydrocarbon in soil include ex-situ thermal desorption technology, ex-situ chemical oxidation technology and biological pile technology. The thermal desorption technology is a commonly used disposal technology for contaminated soil in a disposal site in China, and can be used for disposal of volatile and semi-volatile organic contaminated soil and petroleum hydrocarbon contaminated soil in a site. It is a good treatment method for high-concentration contaminated soil.

[0004] However, the above-mentioned technologies often have the following defects: in the use of the traditional soil thermal desorption system, the soil is generally crushed by a pretreatment module and then conveyed into a thermal desorption drum. Through direct or indirect heat exchange, the organic pollutants in the soil are heated to a sufficient temperature, so that the organic pollutants can be volatilized or separated from the contaminated medium. However, the plastic bags existing in the soil can wrap the soil, thereby reducing the degradation efficiency. After heating, the plastic bags can be heat-shrunk, which may be bonded to the drum wall of the thermal desorption drum, and is not convenient for post-cleaning. Meanwhile, the plastic bags in the soil can also cause pollution after backfilling.

[0005] Therefore, the application provides a device for efficiently degrading high-concentration petroleum hydrocarbon in soil. SUMMARY

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical scheme adopted by the application to solve the technical problems is that the device for efficiently degrading high-concentration petroleum hydrocarbon in soil comprises a feeding module, a conveying module and a thermal desorption module. The conveying module is arranged below the feeding module. The feeding module and the thermal desorption module are connected through the conveying module to jointly constitute a petroleum hydrocarbon degradation device.

[0008] The device further comprises a motor and a support. The support is mounted on the surface of the feeding module. A rotating shaft is rotatably connected to the surface of the support. The rotating shaft is driven by the motor.

[0009] A plurality of pick bars are fixedly connected to the surface of the rotating shaft. The end of each pick bar is arc-shaped.

[0010] A protective cover is fixedly connected to the surface of the bracket, and an installation block is fixedly connected to the surface of the bracket. A recycling mechanism is provided on the surface of the installation block. The recycling mechanism includes a recycling box. A material discharge port is opened on the surface of the recycling box. A comb plate is rotatably connected to the surface of the material discharge port through an elastic element. The comb teeth of the comb plate are "L" shaped. A secondary magnetic block is fixedly connected to the surface of the comb plate, and a main magnetic block is fixedly connected to the surface of the rotating shaft.

[0011] During operation, the soil is broken up by the feeding module and then conveyed to the thermal desorption module via the conveying module. The thermal desorption module degrades petroleum hydrocarbons in the soil. Simultaneously, the motor starts, driving the rotating shaft. This shaft then rotates the lifting rod, which, with its rounded end, lifts the plastic bags out of the soil. The rotation of the shaft also drives the main magnetic block to rotate. When the main magnetic block reaches the position of the secondary magnetic block, the two blocks attract each other using the principle of opposite phase attraction. At the same time, the secondary magnetic block causes the comb plate to adhere to the surface of the rotating shaft. The lever rotates again, scraping off the plastic bags from its surface through the comb plate. After the lever passes the comb plate, the main magnetic block and the auxiliary magnetic block separate. At this time, the elastic element drives the comb plate to reset, and the plastic bags on the surface of the comb plate are thrown into the recycling box by inertia. This cycle repeats. The lever and comb plate work together to pick out impurities from the soil, avoiding the situation where plastic bags cover the soil, which would reduce degradation efficiency and cause the plastic bags to stick to the wall of the thermal desorption roller, making it difficult to clean later. This improves the degradation efficiency and also avoids environmental pollution caused by backfilling soil with plastic bags.

[0012] Preferably, the lever is divided into a main lever and a secondary lever. The main lever is fixedly connected to the surface of the rotating shaft. The main lever and the secondary lever are rotatably connected by an elastic element. The end of the secondary lever is arc-shaped. A crossbar is fixedly connected to the surface of the support. A fixed shaft is fixedly connected to the surface of the crossbar. A top plate is slidably connected to the surface of the fixed shaft by a spring. The surface of the top plate is arc-shaped. A lever is fixedly connected to the surface of the rotating shaft.

[0013] During operation, after the lifting rod rotates to the comb plate position, the length of the comb plate teeth is less than the length of the lifting rod. At this time, the auxiliary rod is forced to rotate around the main rod, which makes it easier to scrape off the plastic bags on the surface of the lifting rod. At the same time, through the rotatable auxiliary rod, after the lifting rod passes the comb plate, the elastic element drives the auxiliary rod to return to its original position. The resulting vibration shakes off the soil adhering to the surface of the lifting rod, avoiding excessive soil adhering to the lifting rod surface, which would cause the gap between the lifting rods to narrow and affect the screening efficiency of plastic bags in the soil. When the rotating shaft rotates, it also drives the lever to rotate, causing the lever to press against the top plate. At this time, the top plate moves downward under force, and at the same time, the spring is compressed to generate elastic force. When the lever passes the top plate, the top plate returns to its original position and hits the conveyor belt, which bounces the soil on the surface of the conveyor belt, preventing plastic bags from settling on the surface of the conveyor belt and preventing the lifting rod from being unable to pick them up. At the same time, the impact can further loosen the soil to facilitate the subsequent thermal desorption treatment.

[0014] Preferably, a horizontal shaft is fixedly connected in the recycling box, a pressing plate is rotatably connected to the surface of the horizontal shaft, a sliding rail is fixedly connected to the surface of the pressing plate, a sliding block is slidably connected to the surface of the sliding rail, an electric telescopic rod is fixedly connected to the surface of the recycling box, and the output shaft of the electric telescopic rod is rotatably connected to the sliding block through the side wall of the recycling box.

[0015] In work, after the thermal desorption is completed, the electric telescopic rod is started, the output shaft of the electric telescopic rod is stretched downward, the sliding block is slid on the surface of the sliding rail at the same time, the pressing plate is rotated around the horizontal shaft at this time, the plastic bag in the recycling box is compressed through the pressing plate, the capacity of the recycling box is improved, and the cleaning frequency of the recycling box is reduced.

[0017] In work, the connecting rod slides at the same time when the pressing plate rotates, because the length of the pull rope is fixed, the pull rope pulls the connecting rod at the same time when the pressing plate rotates, the connecting rod moves with the scraper, the scraper is pulled to the bottom end of the pressing plate, the spring is extruded to generate elastic force at the same time, the dirt and the plastic bag adhered to the surface of the pressing plate are scraped off by the scraper when the pressing plate is reset after extruding the plastic bag, the pressing plate is cleaned, the plug moves at the same time when the connecting rod slides, the convex ring on the surface of the plug is clamped into the notch when the connecting plate moves to the limit position, the pressing plate is reset at this time, the convex ring made of rubber can delay the reset of the connecting rod, the convex ring slowly separates from the notch after the pressing plate is completely reset, the potential energy generated when the spring is reset drives the scraper to reset quickly at the same time, and the cleaning effect of the pressing plate is further improved through the impact and vibration.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0037] Example 1:

[0038] like Figures 1 to 9 As shown in the figure, an efficient device for degrading high concentrations of petroleum hydrocarbons in soil according to an embodiment of the present invention includes a feeding module 1, a conveying module 6, and a thermal desorption module 7.

[0039] It also includes a motor 5 and a bracket 2. The bracket 2 is mounted on the surface of the feeding module 1. A rotating shaft 10 is rotatably connected to the surface of the bracket 2. The rotating shaft 10 is driven by the motor 5.

[0040] A plurality of levers 8 are fixedly connected to the surface of the rotating shaft 10, and the ends of the levers 8 are arc-shaped;

[0041] A protective cover 4 is fixedly connected to the surface of the bracket 2. An installation block 31 is fixedly connected to the surface of the bracket 2. A recycling mechanism is provided on the surface of the installation block 31. The recycling mechanism includes a recycling box 9. A discharge port 17 is opened on the surface of the recycling box 9. A comb plate 18 is rotatably connected to the surface of the discharge port 17 through an elastic element. The comb teeth of the comb plate 18 are "L" shaped. A secondary magnetic block 92 is fixedly connected to the surface of the comb plate 18. A main magnetic block 91 is fixedly connected to the surface of the rotating shaft 10.

[0042] During operation, the soil is broken up by the feeding module 1 and then conveyed to the thermal desorption module 7 by the conveying module 6. The thermal desorption module 7 degrades petroleum hydrocarbons in the soil. Simultaneously, the motor 5 is started, causing the rotating shaft 10 to rotate. The rotating shaft 10 then rotates the lifting rod 8, which, with its rounded end, lifts the plastic bags out of the soil. The rotation of the rotating shaft 10 also drives the main magnetic block 91 to rotate. When the main magnetic block 91 rotates to the position of the auxiliary magnetic block 92, the two magnetic blocks attract each other using the principle of opposite phase attraction. At the same time, the auxiliary magnetic block 92 causes the comb plate 18 to adhere to the surface of the rotating shaft 10. Then, the lifting rod 8 rotates again, scraping off the plastic bag on the surface of the lifting rod 8 through the comb plate 18. After the lifting rod 8 passes the comb plate 18, the main magnetic block 91 and the auxiliary magnetic block 92 disengage. At this time, the elastic element drives the comb plate 18 to reset, and the plastic bag on the surface of the comb plate 18 is thrown into the recycling box 9 by inertia. The cycle repeats. The lifting rod 8 and the comb plate 18 can pick out impurities in the soil, avoiding the situation where plastic bags cover the soil, which would lead to a decrease in degradation efficiency and sticking to the cylinder wall of the thermal desorption roller, making it difficult to clean later. While improving the degradation efficiency, it can also avoid environmental pollution caused by backfilling soil with plastic bags.

[0043] The picking rod 8 is divided into a main rod 15 and a secondary rod 16, the main rod 15 is fixedly connected to the surface of the rotating shaft 10, the main rod 15 and the secondary rod 16 are rotatably connected through an elastic member, the end of the secondary rod 16 is arc-shaped, the surface of the support 2 is fixedly connected with a cross beam 14, the surface of the cross beam 14 is fixedly connected with a fixed shaft 13, the surface of the fixed shaft 13 is slidably connected with a top plate 12 through a spring, the surface of the top plate 12 is arc-shaped, and the surface of the rotating shaft 10 is fixedly connected with a push rod 11;

[0044] When working, the picking rod 8 is rotated to the comb plate 18 position, the length of the comb teeth of the comb plate 18 is smaller than the length of the picking rod 8, at this time, the secondary rod 16 is forced to rotate around the main rod 15, so that the plastic bags on the surface of the picking rod 8 are better scraped off, and at the same time, through the rotatable secondary rod 16, the elastic member can drive the secondary rod 16 to reset after the picking rod 8 passes through the comb plate 18, the vibration generated can shake off the soil adhered to the surface of the picking rod 8, so that the soil adhered to the surface of the picking rod 8 is not too much, the gap between the picking rods 8 is not reduced, and the efficiency of screening the plastic bags in the soil is affected, and when the rotating shaft 10 rotates, the push rod 11 is also driven to rotate, so that the push rod 11 presses the top plate 12, at this time, the top plate 12 is forced to move downward, and the spring is pressed to generate elastic force, when the push rod 11 passes through the top plate 12, the top plate 12 resets and hits the conveyor belt, the soil on the surface of the conveyor belt is bounced up, so that the plastic bags are prevented from sinking on the surface of the conveyor belt and causing the picking rod 8 to be unable to pick up, and at the same time, through the impact, the soil can be further puffed, so as to facilitate subsequent thermal desorption treatment.

[0045] The recovery box 9 is fixedly connected with a horizontal shaft 22, the surface of the horizontal shaft 22 is rotatably connected with a pressing plate 21, the surface of the pressing plate 21 is fixedly connected with a sliding rail 20, the surface of the sliding rail 20 is slidably connected with a sliding block 19, the surface of the recovery box 9 is fixedly connected with an electric telescopic rod 3, and the output shaft of the electric telescopic rod 3 is rotatably connected with the sliding block 19 through the side wall of the recovery box 9;

[0046] When working, after the thermal desorption is completed, the electric telescopic rod 3 is started, so that the output shaft of the electric telescopic rod 3 is stretched downward, and the sliding block 19 is slid on the surface of the sliding rail 20 at the same time, at this time, the sliding block 19 drives the pressing plate 21 to rotate around the horizontal shaft 22, the plastic bags in the recovery box 9 are compressed through the pressing plate 21, so as to improve the capacity of the recovery box 9 and reduce the cleaning frequency of the recovery box 9.

[0047] The surface of the pressing plate 21 is provided with a sliding groove 25, a connecting rod 24 is slidably connected in the sliding groove 25 through a spring, the end of the connecting rod 24 is fixedly connected with a scraper 23, the surface of the scraper 23 is provided with a chamfer, a pull rope 26 is arranged in the recycling box 9, one end of the pull rope 26 is fixedly connected on the recycling box 9, the other end of the pull rope 26 is fixedly connected on the surface of the connecting rod 24, the surface of the connecting rod 24 is fixedly connected with a plug block 29, the surface of the plug block 29 is fixedly connected with a convex ring 30, the plug block 29 and the convex ring 30 are both made of rubber, the surface of the sliding groove 25 is provided with a notch 28 relative to the position of the convex ring 30, the surface of the pressing plate 21 is rotatably connected with a rotating wheel 27, the pull rope 26 is slidably connected in the groove on the surface of the rotating wheel 27.

[0048] When working, the connecting rod 24 slides while the pressing plate 21 rotates, because the length of the pull rope 26 is fixed, the pull rope 26 pulls the connecting rod 24 while the pressing plate 21 rotates, so that the connecting rod 24 drives the scraper 23 to move, the scraper 23 is pulled to the bottom end of the pressing plate 21, and the spring is squeezed to generate elastic force, when the pressing plate 21 is reset after squeezing the plastic bag, the scraper 23 scrapes off the soil and plastic bag adhered to the surface of the pressing plate 21, and the pressing plate 21 is cleaned, when the connecting rod 24 slides, the plug block 29 moves, when the connecting plate moves to the limit position, the convex ring 30 on the surface of the plug block 29 is clamped into the notch 28, then the pressing plate 21 is reset, the convex ring 30 made of rubber can delay the reset of the connecting rod 24, when the pressing plate 21 is completely reset, the convex ring 30 slowly separates from the notch 28, under the driving of the potential energy generated by the spring reset, the scraper 23 is quickly reset, and at the same time, impact occurs, and the cleaning effect of the pressing plate 21 is further improved through vibration.

[0049] Embodiment two:

[0050] As Figures 10 to 11As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the surface of the mounting block 31 is provided with a mounting groove, the surface of the recycling box 9 is fixedly connected with a locking block 32, the locking block 32 is engaged with the surface of the mounting block 31 through the mounting groove, the locking block 32 is provided with a cavity 35, the surface of the locking block 32 is provided with a slot 36, the slot 36 is slidably connected with an insert 37 by a spring, the surface of the mounting block 31 is provided with a slot relative to the position of the insert 37, the surface of the insert 37 is fixedly connected with a connecting shaft 39, the connecting shaft 39... The other end of 9 is slidably connected through the side wall of cavity 35, and an extrusion block 40 is fixedly connected to the end. A sliding shaft 34 is slidably connected to the side wall of cavity 35. A top block 33 is fixedly connected to the end of the sliding shaft 34. The surface of the top block 33 is an arc surface. The end of the sliding shaft 34 away from the top block 33 is slidably connected through the mounting block 31. A pull ring is fixedly connected to the end of the sliding shaft 34 through the mounting block 31. The surface of the extrusion block 40 is provided with rounded corners. The top block 33 has grooves on both sides corresponding to the extrusion block 40, and a rubber pad is fixedly connected in the groove.

[0051] During operation, after prolonged use, the plastic bags stored inside the recycling box 9 need to be cleaned to ensure effective recycling. First, pull the pull ring to move the sliding shaft 34, causing the top block 33 to disengage from the extrusion block 40. Then, a spring causes the insertion block 37 to retract into the empty slot 36, moving it away from the slot and releasing the restriction on the recycling box 9. The recycling box 9 can then be lifted using the pull ring for cleaning. When installation is required, the locking block 32 is inserted into the surface of the mounting block 31, and then the pull ring is pressed down, causing the arc surface of the top block 33 to press against the extrusion block 40. This causes the extrusion block 40 to move the insertion block 37 into the slot. Further pressing down on the top block 33 causes the groove on its surface to fit against the extrusion block 40, thus positioning the extrusion block 40. The insertion block 37, in conjunction with the top block 33, facilitates quick disassembly and cleaning of the recycling box 9.
