Technical Field

[0001] This invention relates to the field of sludge treatment technology, and more specifically to an oily sludge treatment device. Background Technology

[0002] The process of treating sludge involves first evaporating and removing the water from the oily sludge, then burning the oily sludge. The final product does not contain oil, thus achieving the treatment of oily sludge.

[0003] In related technical fields, oily sludge treatment often requires two interconnected chambers. One chamber is used to agitate and evaporate moisture from the oily sludge, while the other chamber is used for incineration. Agitation of the oily sludge is intended to accelerate its heating process. However, when transferring the sludge to the other chamber for incineration, agitation must be stopped and the corresponding conveying device activated, resulting in a lengthy conveying process and impacting the processing speed.

[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Reference Figure 1-11 As shown, the oily sludge treatment device of the present invention includes: a treatment body 1, a stirring assembly 2, a control assembly 3, and a drive assembly 4.

[0037] The processing body 1 comprises a heating chamber 11 for removing moisture from oily sludge and an incineration chamber 12 for removing oil from the oily sludge. The heating chamber 11 is located above the incineration chamber 12. The processing body 1 is a tank.

[0038] The stirring assembly 2 is used to form a stirring element 21 for stirring the oily sludge in the heating chamber 11 and a scraper 22 for scraping the inner wall of the heating chamber 11. In this embodiment, the stirring element 21 is a rod, and the scraper 22 is a plate, which is fixed to the stirring element 21. The stirring element 21 is used to stir the oily sludge in the heating chamber 11, so that the oily sludge is evenly dispersed and can better evaporate moisture by heating in the heating chamber 11.

[0039] The control component 3 is used to form a first baffle 31 with a passageway between the heating chamber 11 and the incineration chamber 12, and a second baffle 32 disposed on the passageway to block the passageway. In this embodiment, both the first baffle 31 and the second baffle 32 are plates. The heating chamber 11 and the incineration chamber 12 are separated by the first baffle 31 and the second baffle 32. The oily sludge in the heating chamber 11 is carried by the first baffle 31 and the second baffle 32. When the incineration chamber 12 incinerates the oily sludge, the heat is transferred to the heating chamber 11 through the first baffle 31 and the second baffle 32, thereby realizing the utilization of the heat in the incineration chamber 12 by the heating chamber 11, reducing energy consumption. Furthermore, the stirring of the stirring component 21 increases the uniformity of heating of the oily sludge in the heating chamber 11, and better facilitates the evaporation and removal of moisture from the oily sludge in the heating chamber 11.

[0040] The drive assembly 4 is used to drive the stirring element 21 to rotate around a movable axis, and to move the movable axis to a first region and a second region. The stirring element 21 is connected to the second stop 32. When the movable axis is in the first region, the scraper 22 is separated from the inner wall of the heating chamber 11, and the second stop 32 blocks the passageway. When the movable axis is in the second region, the scraper 22 can abut against the heating chamber 11, and the passageway between the second stop 32 and the first stop 31 connects the heating chamber 11 and the incineration chamber 12. When the movable axis is located in the first region, the agitator 21 normally agitates the oily sludge in the heating chamber 11. When the movable axis is located in the second region, the agitator 21 can not only agitate the oily sludge, but also scrape off the substances adhering to the inner wall of the heating chamber 11 through the scraper. At this time, the passage will also be opened, thus realizing simultaneous agitation, discharge, and scraping, resulting in faster discharge speed and better discharge effect. The setting of the movable axis in the first and second regions ensures that the scraper 22 does not contact the inner wall of the heating chamber 11 during normal agitation, avoiding excessive resistance to the rotation of the agitator 21, thereby better ensuring the normal rotation of the agitator 21.

[0041] Specifically, the stirring assembly 2 further includes a connector 23 forming a first heat transfer chamber in the incineration chamber 12. In this embodiment, the connector 23 is a rod, and it is fixedly connected to the stirring assembly 21. The stirring assembly 21 has a second heat transfer chamber; the first and second heat transfer chambers are connected and both are filled with a heat exchange medium. In this embodiment, the heat exchange medium is graphene particles, which are used for heat conduction, thereby transferring heat from the combustion chamber to the heat exchange medium in the second heat transfer chamber. The heat exchange medium in the second heat transfer chamber then transfers heat to the first heat transfer chamber, thus raising the temperature of the stirring assembly 21. This achieves the goal of raising the temperature of the oily sludge in the heating chamber 11 through the first baffle 31, the second baffle 32, and the stirring assembly 21, increasing the rate of water evaporation.

[0042] Specifically, when the scraper 22 abuts against the inner wall of the heating chamber 11, the scraper 22 and the inner wall of the heating chamber 11 form an inclined contact surface. More precisely, the scraper 22 is installed at an angle relative to the stirring member 21, thus the contact surface is inclined. This inclined contact surface is designed so that when the scraper 22 contacts the inner wall of the heating chamber 11, the scraping process of the scraper 22, along with the rotation of the stirring member 21, applies a downward force to the material adhering to the inner wall of the heating chamber 11, making it easier for the scraped material to detach from the inner wall of the heating chamber 11 and fall.

[0043] In some embodiments, the first baffle 31 is an annular plate with a first guide surface 311 formed on it. One end of the first guide surface 311 is the inner ring of the annular plate, and the other end is the outer ring, thus the first guide surface 311 is an inclined surface. The first guide surface 311 is connected to the heating chamber 11, meaning it can receive oily sludge in the heating chamber 11, allowing the oily sludge on it to flow downwards. When the passageway between the first baffle 31 and the second baffle 32 connects the heating chamber 11 and the incineration chamber 12, the oily sludge is scraped onto the first guide surface 311, flows downwards along it, and enters the incineration chamber 12.

[0044] In some embodiments, the second baffle 32 is a circular plate, disposed in the middle of the first baffle 31. A second guide surface 321 and a bearing surface 322 are formed on the second baffle 32; the first guide surface 311, the second guide surface 321, and the bearing surface 322 constitute the bottom surface of the heating chamber 11; the second guide surface 321 is used to allow the oily sludge on the second guide surface 321 to flow downwards onto the bearing surface 322; the bearing surface 322 is located below the first baffle 31. The second guide surface 321 is an inclined surface, and the bearing surface 322 is an annular plane, so that when the oily sludge is located on the second guide surface 321, it will flow downwards and better flow along the passageway into the incineration chamber 12.

[0045] Specifically, the stirring element 21 forms multiple stirring lines or surfaces that provide lateral shear force to the oily sludge; the stirring lines or surfaces are parallel to the first guide surface 311, the second guide surface 321, and the bearing surface 322. In this embodiment, the stirring element 21 forms stirring lines, which are the edges on the stirring rod. This arrangement ensures that the extension direction of the stirring rod is parallel to the first guide surface 311, the second guide surface 321, and the bearing surface 322, resulting in a better stirring effect when stirring the oily sludge in the heating chamber 11.

[0046] Specifically, the stirring assembly 2 further includes a pressing member 24; the pressing member 24 is used to form a pressing surface; when the movable axis is located in the second region, the pressing surface coincides with the first guide surface 311 and part of the bearing surface 322. The pressing member 24 is a plate, and the purpose of the pressing surface formed by the pressing member 24 coinciding with the first guide surface 311 and part of the bearing surface 322 is to clean the oily sludge adhering to or falling on the first guide surface 311, accelerate the discharge speed of the oily sludge, and thus quickly add the sludge-containing material from the heating chamber 11 into the incineration chamber 12.

[0047] Specifically, the drive assembly 4 includes a rotary drive 41, a lifting drive 42, and a displacement drive 43. The rotary drive 41 drives the stirring member 21 to rotate around the movable axis, and the displacement drive 43 drives the stirring member 21 to move, so that the movable axis moves to the first region or the second region. The lifting drive 42 drives the stirring member 21 to rise until the bearing surface 322 contacts the first stop 31 or to descend until the bearing surface 322 is separated from the first stop 31. When the bearing surface 322 contacts the first stop 31, the pressure surface is far away from both the first guide surface 311 and the bearing surface 322. When the bearing surface 322 is separated from the first stop 31, the pressure surface coincides with the first guide surface 311 and part of the bearing surface 322.

[0048] The rotary drive component 41 includes a first motor 411, a belt drive structure 412, and a moving frame 413. The displacement drive component 43 includes a guide rail 431, a slider 432, and an electric push rod 433. The lifting drive component 42 includes a lifting cylinder 421 and a support plate 422. The lifting cylinder 421 is mounted on the processing body 1, and its output end is connected to the support plate 422. The lifting cylinder 421 is used to drive the support plate 422 to lift. The guide rail 431 is mounted on the support plate 422, the slider 432 is slidably connected to the guide rail 431, the moving frame 413 is mounted on the slider 432, the electric push rod 433 is mounted on the support plate 422, the first motor 411 is mounted on the moving frame 413, the moving frame 413 forms a moving plate 414, the moving plate 414 is rotatably connected to the stirring component 21, the stirring component 21 is provided with a first clamping plate and a second clamping plate, the moving plate 414 is located between the first clamping plate and the second clamping plate, and the moving plate 414 abuts against the first clamping plate and the second clamping plate through a thrust bearing, thereby realizing the lifting and lowering of the moving frame 413 and driving the main rotating shaft 211 to lift and lower through the moving belt.

[0049] The purpose of the lifting drive 42 is to raise and lower the stirring member 21, the scraper 22, and the pressing member 24. The raising and lowering of the pressing member 24 allows its pressing surface to overlap or not overlap with the first guide surface 311 and part of the bearing surface 322. When the stirring member 21, scraper 22, and pressing member 24 rise, the pressing surface of the pressing member 24 does not overlap with the first guide surface 311 and part of the bearing surface 322, reducing the resistance experienced by the pressing member 24. Furthermore, the pressing member 24 also plays a stirring role as it rotates with the stirring member 21, increasing the stirring effect. The lifting drive 42 can also drive the second stop 32 to rise and fall via the stirring member 21. When the stirring member 21 rises, the second stop 32 is located below the first stop 31, and the first stop 31 contacts the second stop 32, thus completely blocking the passageway. As the agitator 21 descends, the second stop 32 also descends, creating a gap between the first stop 31 and the second stop 32, thus opening the passageway. At this time, the pressure member 24 scrapes the material from the first guide surface 311 and the bearing surface 322. In addition, the displacement drive member 43 moves the movable axis to the second region, causing the agitator 21 to move, which in turn moves the second stop 32. The second stop 32 is offset from the first stop 31, increasing the degree to which the passageway is opened, thereby accelerating the material discharge speed.

[0050] The lifting and lowering of the stirring component 21 will also drive the lifting and lowering of the scraper component 22. The lifting and lowering of the scraper component 22 can scrape the inner wall of the heating chamber 11 at different positions, thus improving the range and effect of scraping.

[0051] In other embodiments, the processing apparatus further includes a fluid conveying member 5; the heat exchange medium is fluid. The heat exchange medium is water or gas, preferably gas. An inlet communicating with the first heat transfer chamber is formed on the connector 23, and an outlet communicating with the second heat transfer chamber is formed on the agitator 21. The fluid conveying member 5 is used to circulate the heat exchange medium between the inlet, the first heat exchange chamber, the second heat exchange chamber, and the outlet. The fluid conveying member includes a connecting hose and a pump body, the pump body being used to circulate the gas between the inlet, the first heat exchange chamber, the second heat exchange chamber, the outlet, and the connecting hose, thereby achieving the heating of the gas by the heat in the combustion chamber 12.

[0052] In some other embodiments, the stirring component 21 includes a main rotating shaft 211, a first rod 212, a second rod 213, and a third rod 214; the main rotating shaft 211 is fixed to the second stop 32, multiple sets of first rods 212 are provided, the axis of the first rod 212 is parallel to the first guide surface 322 and the second guide surface 321, the second rod 213 connects multiple first rods 212, and the third rod 214 connects the second rod 213 to the main rotating shaft 211, and the main rotating shaft 211, the first rod 212, the second rod 213 and the third rod 214 together form a second heat transfer chamber. A baffle is provided in the main rotating shaft 211. The baffle is a solid part of the main rotating shaft 211. The function of the baffle is to allow the gas to flow out of the first heat transfer chamber, pass through the main rotating shaft 211, the first rod 212, the second rod 213, the third rod 214 and the main rotating shaft 211 in sequence, and then enter the connecting hose. As a result, the temperature of the entire stirring component 21 will increase, which will better stir the oily sludge in the heating chamber 11 and thus better increase the rate of water evaporation.

[0053] In other embodiments, the main rotating shaft 211 is rotatably connected to the second stop 32. A first limiting part and a second limiting part are formed on the main rotating shaft 211, and the second stop 32 is located between the first limiting part and the second limiting part, so that when the stirring component 21 is raised and lowered, the second stop 32 can be driven to rise and fall synchronously.
