Description

Technical Field

[0001] The invention belongs to the field of thermal cleaning of oily sludge, in particular to a device for thermal cleaning of oily sludge. Background Art

[0002] Oily sludge refers to sludge mixed with heavy oils such as crude oil, various refined oils, and residual oil. Oily sludge does not exist naturally; rather, it forms due to various industrial, civilian, and personal factors related to crude oil and refined oil, including oilfield extraction, refining, transportation, use, and storage. This sludge is caused by accidents, improper operation, outdated, damaged, and corroded equipment, which causes crude oil and refined oil to escape, leak, and then to the ground, settle on the bottom of oceans, lakes, and rivers, and mix with soil and water to form a mixture of oil, soil, water, and even other pollutants. Oily sludge is harmful to humans, plants, and aquatic life. The evaporated oil vapor in the air can irritate the skin, eyes, and respiratory organs, rendering the land incapable of plant growth. It is difficult to treat and remediate, making it a major pollutant in the petroleum and petrochemical industries.

[0003] The existing oily sludge thermal cleaning device has the following main disadvantages:

[0004] 1. Unable to move. Most of the existing oily sludge cleaning devices are fixed. Oily sludge is collected through various equipment and then transported to the oily sludge hot cleaning device for centralized treatment. Because the oily sludge is scattered all over the place, this treatment method is very time-consuming and labor-intensive.

[0005] 2. The equipment is complex and the treatment process is too long. The existing oily sludge cleaning equipment often has to go through many processes to clean the oily sludge, resulting in low treatment efficiency. Summary of the Invention

When oily sludge that needs to be treated is found, the hydraulic rod is started, and the hydraulic rod drives the first connecting rod to swing, and the first connecting rod drives the second connecting rod to swing. Since the connecting seat is fixedly connected to the inner ring surface of the bearing inside the bearing seat, the second connecting rod drives the bucket to swing around the bearing seat. When the push rod of the hydraulic rod is pushed out, the bucket can be swung counterclockwise, which can bring the bucket close to the ground, and vice versa, it can move the bucket away from the ground. When the bucket is close to the ground, it moves toward the soil containing oily sludge, and the soil containing oily sludge is removed. Shovel up, then start the second drive motor, the second drive motor drives the first sprocket to rotate, the first sprocket drives the second sprocket to rotate through the chain, the second sprocket drives the spiral shaft to rotate, so that the two spiral shafts rotate inward, thereby transporting the oily sludge soil to the middle of the bucket cavity, and then start the first drive motor, the first drive motor drives the spiral shaft inside the auger pipe to rotate, so that the auger pipe transports the oily sludge soil to the inner cavity of the heating chamber, and then start the heating block to heat the oily sludge soil, so that the oil and water in the oily sludge soil are evaporated, and then transported to the inside of the oil-water separator through the first water pipe. After treatment in the oil-water separator, the oily sludge can be separated into oil and water.

[0012] Preferably, the connecting seat is located on the side where the two first connecting platforms are close to each other, and a bearing seat is provided on the side of the connecting seat away from the first connecting platform.

[0015] During operation, the output shaft of the second drive motor is loosely matched with the center hole of the bearing seat, allowing the output shaft of the second drive motor to rotate within the center hole of the bearing seat without causing the internal bearing of the bearing seat to rotate. Because the two spiral shafts spiral in opposite directions, when the two spiral shafts spiral inward, they can each drive an object to move toward the center.

[0016] Preferably, the auger tube passes through the bucket, the auger tube is connected to the interior of the bucket, the end of the auger tube close to the bucket is fixedly connected to the bucket through a limiting flange, the fixed end of the first drive motor is fixedly connected to the outer wall of the end of the auger tube away from the bucket, and the output shaft of the first drive motor passes through the outer wall of the auger tube and is transmission-connected to the internal spiral shaft of the auger tube.

[0017] During operation, the output shaft of the first drive motor penetrates the outer wall of the auger tube and is in transmission connection with the internal spiral shaft of the auger tube, so that the first drive motor can drive the internal spiral shaft of the auger tube to rotate.

[0018] Preferably, crawlers are provided on both sides of the main body. The auger pipe penetrates through the inner wall of the heating chamber and extends to the outside of the main body. A first discharge port is provided at the bottom of one side of the auger pipe close to the heating chamber. Two guide plates are provided at the bottom of the auger pipe.

[0019] During operation, due to the arrangement of the guide plates, the guide plates can provide guidance for the oily sludge, making it move towards the center and preventing some soil from staying on it.

[0020] Preferably, the automatic opening and closing door includes an electric telescopic rod, a fixed platform, a door panel, and limit slide rails. The limit slide rails are respectively located on both sides of the door panel. Limit sliding grooves are provided on one side of the two limit slide rails close to the door panel. The door panel is slidably connected to the limit sliding grooves of the limit slide rails. The door panel is composed of two cubes. A fifth connecting rod is hinged at the top of one side where the two cubes of the door panel are close to each other. An incomplete gear is fixedly provided at one end of the fifth connecting rod away from the door panel. The two incomplete gears are meshed with each other. The two fifth connecting rods respectively penetrate through the outer walls of the two incomplete gears and are hinged to the fixed platform. A third connecting rod is hinged at one side where the two cubes of the door panel are away from each other. One end of the third connecting rod away from the door panel is hinged to the fixed platform.

A through second discharge port is provided at the center of the fixed platform.

[0021] During operation, by starting the electric telescopic rod, the fourth connecting rod can be driven to swing. The swing of the fourth connecting rod drives the swing of the third connecting rod. Since the third connecting rod is parallel to the fifth connecting rod, the swing of the third connecting rod drives one cube of the door panel to move. Through the arrangement of the limit slide rails, the door panel linearly moves through the guidance of the limit slide rails. Due to the meshing of the two incomplete gears with each other, the fifth connecting rod drives one of the incomplete gears to rotate. One of the incomplete gears drives the other incomplete gear to rotate, so that the incomplete gear drives the other fifth connecting rod to swing. The other fifth connecting rod drives the other cube of the door panel to move, so that the two cubes of the door panel move away from each other or close to each other, thus achieving the function of automatically opening and closing the door panel by controlling the electric telescopic rod.

[0022] Preferably, a filter plate is provided at one end of the first water pipe close to the heating chamber. A number of through holes are provided on the outer surface of the filter plate.

The water outlet pipes are communicated with the water pumps inside the oil tank and the water tank. A control chip is provided inside the main body cavity. An Internet of Things remote control system is provided inside the control chip.

[0023] During operation, due to the setting of the filter plate, the filter plate can block the oily sludge. The untreated oily sludge falls into the first water pipe. Due to the setting of the impeller, the rotation of the impeller forms a negative pressure inside the first water pipe to suck the water and oil to be evaporated into the inside of the first water pipe. Due to the setting of the circulating water pipe, it is convenient to dissipate heat from the first water pipe and prevent the first water pipe from deforming due to excessive temperature. Due to the setting of the heat dissipation fins, the heat dissipation surface area is increased, accelerating the dissipation of the heat of the circulating water pipe. Due to the setting of the heat dissipation fan, the heat dissipation efficiency is further accelerated. Due to the setting of the humidity sensor, the humidity sensor can monitor the humidity of the decomposed soil in real time.

Detailed implementation manners

[0036] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0037] As Figures 1 to 5 shown, the present invention provides an oily sludge thermal cleaning device, including: an earthmoving device 10, a decomposition device 20 and a conveying device 30;

[0038] The earthmoving device 10 includes a bucket 1001, a first connecting platform 1002 and a connecting seat 1003. The first connecting platform 1002 is located on both sides of the bucket 1001. One end of the two first connecting platforms 1002 is hinged to the bucket 1001. A connecting seat 1003 is fixedly provided at the end of the two first connecting platforms 902 away from the bucket 1001. The top of the bucket 1001 is hinged with a second connecting rod 1007 through a hinge seat. One end of the second connecting rod 1007 away from the bucket 1001 is hinged with a first connecting rod 1006. The first connecting rod 1006 is hinged to the decomposition device 20 through a hinge seat. The top of the first connecting rod 1006 near the second connecting rod 1007 is hinged with a hydraulic rod 1005 through a hinge seat;

[0039] The decomposition device 20 includes a main body 2001, wherein a partition 2017 is provided in the middle of the main body 2001. The partition 2017 divides the inner cavity of the main body 2001 into two compartments: a heating compartment 2018 and a separation compartment 2019. The inner cavity of the heating compartment 2018 is provided with an auger pipe, and a first drive motor 2006 is driven at one end of the auger pipe close to the heating compartment 2018. Heating blocks 2009 are fixed on both sides of the inner side of the heating compartment 2018. The inner cavity of the separation compartment 2019 is provided with an oil-water separator 2014, and a first water pipe 2013 is provided on one side of the oil-water separator 2014. The first water pipe 2013 passes through the partition 2017 and is connected to the heating compartment 2018.

[0040] The conveying device 30 includes a second drive motor 3001, which is a dual-axis motor. The second drive motor 3001 is located at the top of the main body 2001. The second drive motor 3001 is provided with a first sprocket 3003 on both sides of the transmission. A second sprocket 3005 is provided on one side of the first sprocket 3003. A chain 3004 is engaged with the second sprocket 3005. The first sprocket 3003 and the second sprocket 3005 are connected by the chain 3004. A spiral shaft 3006 is provided on the side where the two second sprockets 3005 are close to each other.

[0041] During operation, the operator can connect to the control panel inside the device via the network using a mobile phone or computer, and control the internal components of the device through the Internet of Things remote control system. The device can be moved by driving the crawler 2002. When oily sludge that needs to be processed is detected, the hydraulic rod 1005 is activated. The hydraulic rod 1005 drives the first connecting rod 1006 to swing, and the first connecting rod 1006 drives the second connecting rod 1007 to swing. Since the connecting seat 1003 is fixedly connected to the inner ring surface of the bearing inside the bearing seat 1004, the second connecting rod 1007 drives the bucket 1001 to swing around the bearing seat 1004. When the push rod of the hydraulic rod 1005 is extended, the bucket 1001 can swing counterclockwise, bringing the bucket 1001 closer to the ground. Conversely, the bucket 1001 can be moved away from the ground. After the bucket 1001 approaches the ground, it then moves towards the soil with oily sludge and shovels up the soil with oily sludge. Then, the second drive motor 3001 is activated. The second drive motor 3001 drives the first sprocket 3003 to rotate. The first sprocket 3003 drives the second sprocket 3005 to rotate through the chain 3004. The second sprocket 3005 drives the screw shaft 3006 to rotate, causing the two screw shafts 3006 to rotate spirally inward, thereby conveying the soil with oily sludge towards the middle of the inner cavity of the bucket 1001. Then, the first drive motor 2006 is activated. The first drive motor 2006 drives the screw shaft 3006 inside the auger pipe 2005 to rotate, so that the auger pipe 2005 conveys the soil with oily sludge to the inner cavity of the heating chamber 2018. Then, the heating block 2009 is activated to heat the soil with oily sludge, so that the oil and water in the soil with oily sludge are evaporated. Then, it is conveyed to the inside of the oil-water separator 2014 through the first water pipe 2013. After being processed by the oil-water separator 2014, the oily sludge can be separated into oil and water.

[0042] As a specific embodiment of the present invention, the connecting seat 1003 is located on the side where the two first connecting platforms 1002 are close to each other. A bearing seat 1004 is provided on the side of the connecting seat 1003 away from the first connecting platform 1002.

Through holes for weight reduction 1008 are respectively provided on the outer surfaces of the first connecting rod 1006 and the second connecting rod 1007.

[0043] During operation, one end of the hydraulic rod 1005 away from the second connecting rod 1007 is hinged to the main body 2001 through a hinge seat, enabling the hydraulic rod 1005 to rotate around the main body 2001. The first connecting rod 1006 is hinged to the main body 2001 through a hinge seat, enabling the first connecting rod 1006 to rotate around the main body 2001. Through the arrangement of the weight-reducing groove 1008, while ensuring the strength of the first connecting rod 1006 and the second connecting rod 1007, the weight can be reduced, thereby reducing the load on the hydraulic rod 1005.

[0044] As a specific embodiment of the present invention, two groups of first sprockets 3003, second sprockets 3005 and chains 3004 are all located inside the two first connecting platforms 1002, and the first sprockets 3003 and second sprockets 3005 are respectively rotatably connected to the first connecting platforms 1002. Bearing seats 1004 are located on both sides of the second driving motor 3001. The output shaft of the second driving motor 3001 is in clearance fit with the central circular hole of the bearing seat 1004. The fixed end of the second driving motor 3001 is fixedly connected to the main body 2001. The spiral directions of the two spiral shafts 3006 are opposite.

A second connecting platform 3008 is fixedly provided at the top of the fixed seat 3007. The second connecting platform 3008 is fixedly connected to the bucket 1001.

[0045] During operation, due to the clearance fit between the output shaft of the second driving motor 3001 and the central hole of the bearing seat, the output shaft of the second driving motor 3001 can rotate within the central hole of the bearing seat 1004 without driving the bearings inside the bearing seat to rotate. Since the spiral directions of the two spiral shafts 3006 are opposite, when the two spiral shafts 3006 rotate spirally inward, the two spiral shafts 3006 can respectively drive the objects to move towards the middle.

A through-round hole is provided at the bottom of the guide plate 2008. An automatic opening and closing door 210 is fixedly provided at the bottom of the guide plate 2008.

[0049] During operation, due to the arrangement of the guide plates 2008, the guide plates 2008 can provide guidance for the oily sludge, causing it to move towards the center and preventing some soil from staying on it.

[0050] As a specific embodiment of the present invention, the automatic opening and closing door 210 includes an electric telescopic rod 2101, a fixed platform 2107, a door panel 2108, and limit slide rails 2109.

The swing of the fourth connecting rod 2103 drives the third connecting rod 2102 to swing. Since the third connecting rod 2102 and the fifth connecting rod 2104 are parallel to each other, the swing of the third connecting rod 2102 drives one of the cubes of the door panel 2108 to move. The provision of the limit slide rail 2109 enables the door panel 2108 to linearly move under the guidance of the limit slide rail 2109. By the meshing of two incomplete gears 2105, the fifth connecting rod 2104 drives one of the incomplete gears 2105 to rotate. One of the incomplete gears 2105 drives the other incomplete gear 2105 to rotate, so that the incomplete gear 2105 drives the other fifth connecting rod 2104 to swing. The other fifth connecting rod 2104 drives the other cube of the door panel 2108 to move, so that the two cubes of the door panel 2108 move away from or close to each other, thus achieving the function of automatic opening and closing.

[0052] As a specific embodiment of the present invention, a filter plate 2012 is provided at one end of the first water pipe 2013 close to the heating chamber 2018. A number of through holes are provided on the outer surface of the filter plate 2012. An impeller is provided inside the first water pipe 2013. A third drive motor is provided on one side of the impeller in a transmission manner. The fixed end of the third drive motor is fixedly connected to the first water pipe 2013 through a fixing frame. A humidity sensor 2020 is provided on the top of the fixed table 2107. The circulating water pipe 2010 is wound around the outer surface of the first water pipe 2013. Heat dissipation fins 2003 are respectively fixedly provided on the top of the separation chamber 2019 and the top of the inner cavity of the separation chamber 2019. A heat dissipation fan 2004 is provided on the top of the heat dissipation fins 2003. One side of the circulating water pipe 2010 away from the first water pipe 2013 is fixedly connected to the main body 2001 through the heat dissipation fins 2003. The first water pipe 2013 penetrates through the heat dissipation fins 2003. An oil tank 2015 and a water tank 2016 are fixedly provided on one side of the oil-water separator 2014 away from the first water pipe 2013. The oil tank 2015 and the water tank 2016 are communicated with the output end of the oil-water separator 2014 through a water pipe. A water pump 2011 is provided inside the oil tank 2015 and the water tank 2016. Water outlet pipes are provided on one side of the oil tank 2015 and the water tank 2016 away from the oil-water separator 2014. The water outlet pipes are communicated with the water pumps 2011 inside the oil tank 2015 and the water tank 2016. A control chip is provided in the inner cavity of the main body 2001. An Internet of Things remote control system is provided inside the control chip.

[0053] During operation, through the setting of the filter plate 2012, the filter plate 2012 can block the oily sludge. The untreated oily sludge falls into the first water pipe 2013. Through the setting of the impeller, the rotation of the impeller forms a negative pressure in the first water pipe 2013 to suck the water and oil to be evaporated into the inside of the first water pipe 2013. Through the setting of the circulating water pipe 2010, it is convenient to dissipate heat from the first water pipe 2013 and prevent the first water pipe 2013 from deforming due to excessive temperature. Through the setting of the heat dissipation fins 2003, the heat dissipation surface area is increased, accelerating the dissipation of heat from the circulating water pipe 2010. Through the setting of the heat dissipation fan, the heat dissipation efficiency is further accelerated. Through the setting of the humidity sensor 2020, the humidity sensor 2020 can monitor the humidity of the decomposed soil in real time.

[0054] The specific working process is as follows:

[0055] The staff can connect to the control panel inside this device through the network via a mobile phone or computer, and control the internal components of this device through the Internet of Things remote control system. The device can be moved by driving the crawler 2002. When it is found that oily sludge needs to be processed, the hydraulic rod 1005 is started. The hydraulic rod 1005 drives the first connecting rod 1006 to swing. The first connecting rod 1006 drives the second connecting rod 1007 to swing. Since the connecting seat 1003 is fixedly connected to the inner ring surface of the bearing inside the bearing seat 1004, the second connecting rod 1007 drives the bucket 1001 to swing around the bearing seat 1004. When the push rod of the hydraulic rod 1005 is pushed out, the bucket 1001 can swing counterclockwise, making the bucket 1001 close to the ground. Conversely, the bucket 1001 can be moved away from the ground. After the bucket 1001 is close to the ground, it then moves towards the soil with oily sludge and shovels up the soil with oily sludge. Then, the second drive motor 3001 is started. The second drive motor 3001 drives the first sprocket 3003 to rotate. The first sprocket 3003 drives the second sprocket 3005 to rotate through the chain 3004. The second sprocket 3005 drives the spiral shaft 3006 to rotate, causing the two spiral shafts 3006 to rotate spirally inward, so as to convey the oily sludge towards the middle of the inner cavity of the bucket 1001.

[0056] Then, start the first drive motor 2006. The first drive motor 2006 drives the spiral shaft 3006 inside the auger pipe 2005 to rotate, so that the auger pipe 2005 conveys the soil with oily sludge to the inner cavity of the heating chamber 2018. The oily sludge will first accumulate on the guide plate 2008 in the middle of the heating chamber 2018. By starting the electric telescopic rod 2101, the fourth connecting rod 2103 can be driven to swing. The swing of the fourth connecting rod 2103 drives the third connecting rod 2102 to swing. Since the third connecting rod 2102 and the fifth connecting rod 2104 are parallel to each other, the swing of the third connecting rod 2102 drives one of the cubes of the door panel 2108 to move. The arrangement of the limit slide rail 2109 enables the door panel 2108 to linearly move along the guidance of the limit slide rail 2109. Through the meshing of the two incomplete gears 2105, the fifth connecting rod 2104 drives one of the incomplete gears 2105 to rotate. One of the incomplete gears 2105 drives the other incomplete gear 2105 to rotate, so that the incomplete gear 2105 drives the other fifth connecting rod 2104 to swing. The other fifth connecting rod 2104 drives the other cube of the door panel 2108 to move, so that the two cubes of the door panel 2108 move away from or close to each other, thus achieving the function of automatically opening and closing the door panel 2108 by controlling the electric telescopic rod 2101. When the automatic opening and closing door 210 is opened, the oily sludge will slide down from the second discharge port 2110 and fall onto the guide plate 2008 at the bottom of the heating chamber 2018. Then, close the automatic opening and closing door 210 to seal the oily sludge. Then, start the heating block 2009 to heat the soil with oily sludge, so that the oil and water in the soil with oily sludge are evaporated. Then, start the third drive motor, so that the third drive motor drives the impeller to rotate. The rotation of the impeller forms a negative pressure in the first water pipe 2013 to suck the evaporated water and oil into the first water pipe 2013. The circulating water pipe 2010 can dissipate heat from the first water pipe 2013. Start the water pump 2011, so that the water pump 2011 drives the water in the circulating water pipe 2010 to flow, so that the water below the circulating water pipe 2010 is exchanged with the water above the circulating water pipe 2010. Then, accelerate the heat dissipation through the heat dissipation fins 2003 and the heat dissipation fan 2004. Then, it is conveyed to the inside of the oil-water separator 2014 through the first water pipe 2013. After the treatment of the oil-water separator 2014, the oily sludge can be separated into oil and water, and then stored in the oil tank 2015 and the water tank 2016 respectively. The oil and water can be transferred through the outlet pipes of the oil tank 2015 and the water tank 2016. Finally, start the automatic opening and closing door 210 at the bottom of the heating chamber 2018, so that the oily sludge slides out from the second discharge port 2110 of the automatic opening and closing door 210.
