Description

Technical Field

[0001] This invention belongs to the field of oil extraction technology, specifically relating to a slag removal device, a slag removal method, and an extractor. Background Technology

[0002] In the current market, the mixed oil circulation system of the leaching tank is a process in which the mixed oil in the oil collection hopper is directly connected to the circulation pump through a pipeline, and then directly pumped into the spraying device. The main problems in this process are: the material entering the leaching tank carries a large amount of powder and slag, and powder and slag are also generated during the leaching process. This powder and slag enter the mixed oil collection hopper along with the mixed oil. The mixed oil in the collection hopper is then pumped back to the leaching tank for circulation and spraying by the circulation pump. The mixed oil that is circulated and sprayed also carries the powder and slag in the collection hopper back to the material bed.

[0003] A small amount of powder residue will not have a significant impact on leaching, but excessive powder residue will affect the solvent penetration rate in the bed, resulting in the residual oil content of the leached material failing to meet standards. Simultaneously, during circulating spraying, the mixed oil is sprayed onto the bed through a spraying device. The secondary mixed oil distribution tank in the spraying device will also become filled with a large amount of powder residue brought from the oil collecting hopper, disrupting the spraying effect and reducing the leaching efficiency.

[0004] Over time, the powder and slag in the oil collection hopper and distribution tank accumulate more and more. Especially for the distribution tank, if it is full of powder and slag, it becomes useless and loses its function. And with the current technology, it is difficult to avoid powder and slag in the leachator.

[0005] Therefore, providing a device that can remove most of the powder residue during the production process is an urgent problem to be solved. Summary of the Invention

[0006] To solve the above technical problems, the technical solution of the present invention is as follows:

[0007] The first objective of this invention is to provide a sludge removal device capable of removing most of the powder and sludge from mixed oil, comprising: a rotating mechanism, a chute assembly, and a sludge removal mechanism. The sludge removal mechanism includes:

[0008] The shell has a shell inlet at the top and its internal cavity is divided into a slag outlet cavity and an oil outlet cavity; the slag outlet cavity is connected to the slag outlet pipe assembly and the oil outlet cavity is connected to the oil outlet pipe assembly.

[0009] The swing assembly includes a separation plate assembly located inside the housing to separate oil and sludge from the sludge-containing mixed oil entering through the housing inlet;

[0010] The drive module drives the swing assembly to pour the powder and slag intercepted by the filter on the separation plate assembly into the slag discharge chamber.

[0011] In the above scheme, the separation plate assembly filters the slag-containing mixed oil entering the shell. The filtered mixed oil is discharged through the oil outlet chamber and oil outlet pipe assembly. The drive module drives the separation assembly to move so that the separation plate assembly can pour the filtered and intercepted powder and slag into the slag outlet chamber and discharge it through the slag outlet pipe assembly.

[0012] Furthermore, the internal cavity of the shell is a fan-shaped cavity, with a V-shaped inner plate at the bottom dividing the fan-shaped cavity into an upper fan-shaped oil outlet cavity and a lower V-shaped slag outlet cavity. The top two ends of the V-shaped slag outlet cavity serve as slag collection ports. Specifically:

[0013] The shell is fan-shaped, with a rounded upper part and inward-curving lower sides. This design allows the mixed oil to be collected within the shell cavity while ensuring complete drainage, preventing any residue from remaining inside. The lower part of the shell has an oil outlet (located in the oil outlet chamber) and a slag outlet (located in the slag outlet chamber). The oil outlet connects to an oil outlet pipe assembly, which in turn connects to a circulating pump. The mixed oil is pumped through the oil outlet pipe assembly to the spraying device. The slag outlet connects to the slag outlet pipe assembly, which can be connected to a conveying device to remove the powdered slag separated from the slag removal mechanism. The slag outlet is connected to the slag outlet chamber, which is located on the outer periphery of the shell's internal cavity. When the separating plate rotates and swings downwards at an angle, it aligns precisely with the slag collection port of the slag outlet chamber.

[0014] Furthermore, the separating plate assembly includes a first separating plate and a second separating plate, the two separating plates being arranged at an angle; through the driving module, one separating plate is selectively aligned with the feed inlet of the shell, while the other separating plate is aligned with the slag collection outlet of the slag discharge chamber. Specifically:

[0015] The housing inlet faces directly upwards, and the swing assembly is located directly below the housing inlet. The swing assembly includes a separation plate assembly consisting of two separation plates, a shaft, a sealing assembly, and a bearing assembly. The shaft is installed inside the housing, with its two ends rotatably assembled with the housing, and one end extending out of the housing. The two separation plates are connected to the shaft via support rods.

[0016] Two separation plates are fixed on the shaft and can rotate with the shaft. The two separation plates are arranged at a certain angle. When one separation plate is working, the other is in an oblique downward state. The separation plate in the working state is directly facing the inlet of the shell, achieving the effect of oil and sludge separation. The separation plate in the non-working state is obliquely facing the sludge collection port.

[0017] Furthermore, both separation plates have an upward curve around the edges and a concave surface in the middle to prevent the filtered residue from overflowing. The upward curve around the edges of the separation plate is a solid plate, which prevents residue from overflowing during filtration. The concave surface is a perforated plate, which is used for filtration. The mixed oil flows into the shell at the bottom of the separation plate, while the residue remains on the upper surface of the separation plate.

[0018] Furthermore, a rinsing assembly is provided next to the feed inlet of the housing for rinsing the separation plate assembly. Specifically:

[0019] The flushing assembly includes branch pipes on both sides of the feed inlet of the shell and several flushing ports arranged downwards on the branch pipes. When the separation plate is in the downward position, i.e., in the non-working state, the flushing assembly flushes the powder and slag on the separation plate over a large area (the flushing liquid of the flushing assembly can be fresh solvent or mixed oil). Since the separation plate is tilted downwards and is aligned with the slag collection port, all the flushed powder and slag flows into the slag discharge chamber. The slag discharge chamber is vertical on one side and arranged with three oblique cones, which can make the powder and slag flow well into the slag discharge hole and enter the slag discharge pipe assembly.

[0020] Furthermore, the drive module includes a cylinder and a connecting rod. The cylinder is installed outside the housing, one end of the connecting rod is movably connected to the push rod of the cylinder, and the other end is fixedly connected to the extended end of the shaft. The cylinder drives the push rod to extend and retract, and the connecting rod realizes the rotation and swing of the separation plate assembly around the shaft.

[0021] Through the drive module, the swing assembly in the slag removal mechanism can rotate back and forth around the shaft at a 45° swing angle. Every 45° rotation, one separation plate has its upper surface facing the feed inlet of the shell, while the other separation plate is angled downwards and aligned with the slag collection port of the slag outlet. The shaft end of the swing assembly is movably connected to the cylinder push rod outside the shell. The cylinder controls the dwell time of the swinging separation plate by controlling a time relay according to a preset time. The drive module is not fixedly installed; the head of the cylinder push rod is movably connected to the lower end of the connecting rod, while the upper end of the connecting rod is fixed to the extended end of the shaft.

[0022] When the push rod extends, it pushes the lower end of the connecting rod, whose upper end connects to the shaft. The lower end of the connecting rod then moves in an arc around the shaft, while the shaft rotates in a circle around its center. The separating plate connected to the shaft also rotates in a certain arc along with the shaft. When one separating plate is in operation, after a set time, the push rod is retracted to its original position. At this time, the other separating plate rotates with the shaft to face the feed inlet of the housing. After the set time, the push rod extends again, and the separating plates oscillate around the shaft in this cycle.

[0023] Furthermore, the device also includes a rotating mechanism, which comprises a cylinder, a rotating shaft with blades located inside the cylinder, a drive module, a sealing assembly, and a bearing assembly. The cylinder wall has a cylinder inlet and a cylinder outlet; the rotating shaft is rotatably mounted to both ends of the cylinder, and its outer wall has several blades; driving the rotating shaft to rotate causes the blades to rotate synchronously, thereby transporting and agitating the slag-containing mixed oil. Specifically:

[0024] The upper side of the cylinder wall has a through hole for welding with a hollow circular tube and a flange. The flange connects to the outlet of the oil collecting hopper of the extractor. The rotating shaft is inside the cylinder. When the oil collecting hopper contains mixed oil, the bladed rotating shaft rotates, drawing the slag-containing mixed oil into the cylinder. A through hole on the left side of the cylinder serves as the cylinder outlet. The rotating shaft with blades transports the slag-containing mixed oil inside the cylinder to the outlet on the left side of the cylinder.

[0025] A rotating mechanism is connected to the bottom of the oil collecting hopper. Its main functions are: 1. to transport the slag-containing mixed oil through blades that rotate together with the shaft; 2. to accelerate the flow rate of the slag-containing mixed oil, so that the mixed oil in the cylinder can enter the slag removal mechanism at a faster speed, thereby increasing the filtration effect; 3. to disrupt the flow of the slag-containing mixed oil, so that the powder and slag are always in a suspended and irregular motion state.

[0026] Furthermore, the length of the blades along the axial direction is shorter than the length along the cylinder axis (i.e., there is a certain distance between the two ends of the blades and the two ends of the cylinder), forming two gap spaces at both ends of the inner cavity of the cylinder. The effective working area of ​​the blades is smaller than the maximum cross-sectional area of ​​the cylinder axis, but larger than the discharge port area of ​​the cylinder. This effectively transports the mixed oil to the discharge port of the cylinder while causing the mixed oil to form a turbulent flow within the cylinder, preventing the sedimentation of powder and slag.

[0027] When the gap space is filled with mixed oil, the cylinder outlet faces the blades as the blades rotate. The area of ​​the cylinder outlet is slightly smaller than the effective working area of ​​several blades. In this way, the blades can not only transport the mixed oil, but also cause the slag-containing mixed oil in the gap space on both sides of the cylinder to be disturbed due to the rotation of the blades. Since the cylinder outlet is opened on the left side of the cylinder and the two sides of the cylinder are connected to the arc-shaped end faces, the powder and slag inside will fall down along the arc surface of the arc end face without dead corners. The slag-containing mixed oil in the gap space on both sides of the cylinder will flow towards the cylinder outlet with lower pressure, thus forming a convection-like phenomenon. The powder and slag in the gap space on both sides of the cylinder are disturbed and mixed with the mixed oil, and at the same time, they are convected and flow quickly with the mixed oil to the cylinder outlet and enter the chute. The powder and slag in the mixed oil do not have a directional flow that causes accumulation and sedimentation.

[0028] Furthermore, the device also includes a chute assembly, which comprises a chute and a disruptive flow rod. The chute is an arc-shaped hollow structure open at both ends, with its two ends respectively connected to the cylinder outlet of the rotating mechanism and the shell inlet of the slag removal mechanism; the disruptive flow rod is fixed inside the cavity of the chute and arranged perpendicular to the length of the chute. Specifically:

[0029] The discharge port of the cylinder in the rotating mechanism and the inlet of the chute are connected by welding (or by flange), and the discharge port of the chute and the inlet of the shell in the slag removal mechanism are connected by welding (or by flange).

[0030] The chute extends in a certain arc-shaped curve, with the inlet facing upwards at a certain angle to the horizontal and the outlet facing downwards. The middle is arc-shaped. When the slag-containing mixed oil enters the chute, it will follow the arc direction of the chute from the rotating mechanism to the slag removal mechanism. When it enters the chute inlet for a certain distance, the slag-containing mixed oil will impact the turbulence rods inside the chute. The flow direction of the mixed oil is along the turbulence rods. After being blocked by several turbulence rods, the flow of the mixed oil will become chaotic, which will make the powder and slag originally mixed in the mixed oil move more irregularly. This ensures that before entering the slag removal mechanism, the powder and slag will not accumulate at the inlet of the chute or the slag removal mechanism due to normal flow.

[0031] The second objective of this invention is to provide a slag removal method, comprising:

[0032] First, the slag-containing mixed oil enters the cylinder through the feed inlet, driving the rotating shaft inside the cylinder. The blades on the rotating shaft rotate synchronously, disturbing the flow of the slag-containing mixed oil and keeping the powder and slag in a suspended state.

[0033] Next, the slag-containing mixed oil enters the arc-shaped shell from the discharge port of the cylinder under the drive of the blades, and flows along the turbulence rod inside the shell, making the flow of the slag-containing mixed oil chaotic and the irregular movement of the powder and slag even more intense.

[0034] Then, the slag-containing mixed oil enters the shell feed inlet through the chute. The first separation plate in the separation plate assembly is directly opposite the shell feed inlet. After the mixed oil is filtered by the first separation plate, it flows into the oil outlet chamber. The powder and slag intercepted by the filter remain on the first separation plate. At this time, the second separation plate is aligned with the slag collection port of the slag outlet chamber.

[0035] The drive module causes the separation plate assembly to rotate and swing. The first separation plate rotates and aligns with the other slag collection port of the slag discharge chamber, pouring the powder and slag into the slag discharge chamber. At the same time, the second separation plate aligns with the feed port of the shell to separate oil and slag.

[0036] The drive module is reset, causing the first separation plate to align with the shell inlet again and the second separation plate to align with the slag collection port. The first and second separation plates alternately perform oil-liquid separation and powder / slag dumping.

[0037] Finally, the filtered slag is discharged through the slag discharge pipe assembly connected to the slag discharge chamber, and the filtered mixed oil flows out through the oil discharge pipe assembly connected to the oil discharge chamber.

[0038] By adopting the above-mentioned slag removal method, the slag content in the circulating mixed oil is reduced, which makes it less likely for slag to accumulate in the secondary distribution tank and affect the function of the spraying device. At the same time, the slag content in the material bed is reduced, the permeability is improved, the leaching effect is optimized, and excellent leaching indicators are obtained.

[0039] The third objective of this invention is to provide a leachator comprising the aforementioned slag removal device, which is installed between the oil collecting hopper and the spraying device of the leachator. Before the mixed oil leaves the oil collecting hopper and enters the spraying device, most of the powder and slag mixed in the mixed oil are removed, thus preventing the mixed oil containing a large amount of powder from accumulating in the distribution tank and reducing the powder content in the bed, thereby improving the leaching efficiency and achieving a more satisfactory leaching index.

[0040] Compared with existing mechanisms, the present invention has the following advantages:

[0041] 1. Slag removal can be performed continuously during the production process without stopping the machine for maintenance;

[0042] 2. Automatic slag removal eliminates the need for additional manual processing;

[0043] 3. Reduces the powder content in the feed bed;

[0044] 4. To prevent powder and slag from accumulating in the distribution tank of the spray device. Attached Figure Description

[0057] A slag removal device, such as Figure 1 As shown, it includes a rotating mechanism 1, a chute assembly 2, and a slag removal mechanism 3.

[0058] 1. Regarding the rotating mechanism

[0059] The rotating mechanism consists of a drive module 11, a flange 12, a sealing assembly 13, a cylinder 14, a rotating shaft 17 with blades 15, and a bearing assembly 16.

[0060] In one embodiment of the present invention, such as Figure 9 As shown, a round hole is opened at the upper end of the cylinder 14, and the round hole is welded to the hollow round tube 18 and the flange 12. The flange 19 is connected to the oil outlet flange of the oil collection hopper of the extractor. A square hole is opened at the lower front of the cylinder 14 as the cylinder outlet 143. Arc-shaped end faces 141 are welded on both sides of the cylinder 14. The two arc-shaped end faces 141 are coaxial with the cylinder. A flat end plate 142 is welded to the small round hole of the arc-shaped end face 141 for connecting the bearing assembly 16.

[0061] In one embodiment of the present invention, such as Figure 2As shown, bearing assemblies 16 are connected to both outer sides of the flat end plate 142. Sealing assemblies 13 are mounted on the outer sides of the bearing assemblies 16. A rotating shaft 17 is installed inside the cylinder 14, coaxial with the cylinder 14, and passes through the bearing assemblies 16 and the sealing assemblies 13. Several blades are mounted on the rotating shaft, and the blades rotate coaxially together. A drive module 11 is installed on the right side of the cylinder, and the drive module 11 is connected to the right end of the rotating shaft 17.

[0062] 2. Regarding the chute assembly

[0063] The chute assembly 2 includes a chute and a turbulent flow rod 22. The discharge port 143 of the rotating mechanism is connected to the inlet of the chute, and the outlet of the chute faces downward and is connected to the feed port of the shell of the slag removal mechanism. The chute is composed of an upper arc plate 21, a lower arc plate 23, and a side plate 24. The turbulent flow rod 22 is arranged perpendicular to the length of the chute, and the chute is a hollow square tube with a certain curvature.

[0064] In one embodiment of the present invention, such as Figure 3 As shown, the right side is the upper arc plate 21, and the left side is the lower arc plate 23. The upper and lower arc plates are connected to each other by side plates 24 on the front and back sides to form an arc-shaped square tube. Several turbulence tubes 22 are welded inside the tube upwards. The turbulence rods are distributed and staggered, and the two ends of the turbulence rods are welded to the two side plates respectively.

[0065] 3. Regarding slag removal agencies

[0066] Below the chute assembly is a slag removal mechanism 3, and the outlet of the chute assembly is connected to the feed inlet of the slag removal mechanism housing. The internal cavity of the housing is a fan-shaped cavity. The lower part of the internal cavity of the housing 33 is provided with a V-shaped inner plate 339, which divides the fan-shaped cavity into an upper fan-shaped oil outlet cavity 337 and a lower V-shaped slag outlet cavity 338. The top two ends of the V-shaped slag outlet cavity serve as slag collection ports.

[0067] In one embodiment of the present invention, such as Figure 8As shown, flange 331, arc plate 332, flange end plate 333, end plate 334, bottom plate 335, flange gasket 336, and V-shaped inner plate 339 are connected to form a fan-shaped cavity shell 33. The bottom plate 335 is V-shaped and parallel to the inner plate 339, and is a certain distance away from it, forming a V-shaped cavity, which serves as the slag discharge cavity 338. The top two ends of the V-shaped inner plate 339 of the slag discharge cavity 338 are bent inward at a certain angle, forming the slag collection port of the slag discharge cavity between it and the bottom plate 335. The slag discharge pipe assembly 36 is connected to the front part of the inner plate 339 directly below, and the slag discharge pipe assembly 36 is connected to the slag discharge port 3381 of the slag discharge cavity 338. The inner plate 339 has a circular hole at its bottom, located in front of the slag discharge pipe assembly. This hole connects to the oil outlet 3371. The inner plate 339, along with the end plate 334 and flange end plate 333 inside the housing 33, forms a cavity for collecting the filtered mixed oil, serving as the oil outlet cavity 337. The mixed oil in this cavity flows into the oil outlet through the circular hole at the bottom of the inner plate. The oil outlet 3371 connects to the oil discharge pipe assembly 35. The end plates and flange end plates at the front and rear of the housing each have coaxial holes. Bearing assemblies are installed on the outside of these holes, and sealing assemblies are installed outside the bearing assemblies.

[0068] The swing assembly 34 includes a separation plate assembly 341 consisting of two separation plates, a shaft 342, a sealing assembly, and a bearing assembly; the shaft 342 is installed inside the housing, with its two ends rotatably assembled with the housing, and the shaft 342 passes through the bearing assembly and the sealing assembly, as shown below. Figure 6 As shown, one end of shaft 342 extends outside the sealing assembly, one end of array support rods is welded to shaft 342, and the other end supports separation plate assembly 341.

[0069] like Figure 7 As shown, the separation plate assembly 341 has two separation plates 3411 arranged at an angle, and the two separation plates are connected to the shaft 342 by support rods 343 respectively. The separation plates 3411 are all of the structure with upward curves around the edges and a concave plane in the middle. The concave plane in the middle includes horizontal ribs 3413, vertical ribs 3412, and filter holes.

[0070] In one embodiment of the present invention, such as Figure 6 As shown, a section of the shaft 342 of the swing assembly 34 extends beyond the flange end plate. A connecting rod 38 is fixedly sleeved on the extended shaft. A threaded section with a nut at the front end of the shaft 342 prevents the connecting rod from detaching from the shaft end. The other end of the connecting rod 38 is connected to the push rod 37 of the cylinder 31, which moves back and forth. The cylinder's push or retraction of the push rod causes the connecting rod to swing around the shaft. The rotation of the shaft, in turn, causes the separation plate assembly, fixed by the support rod 343, to swing back and forth. During operation, one separation plate always faces the feed inlet of the housing, ensuring that the slag-containing mixed oil falls onto the separation plate. The two separation plates are positioned such that one faces upwards and the other angled downwards.

[0071] In one embodiment of the present invention, such as Figure 4 As shown, a flushing assembly 32 is installed on the upper part of the shell. There are two parallel branch pipes on both sides of the shell inlet. The two branch pipes converge into a main pipe. The end of the main pipe is welded with a flange for connection to the external pipeline. Several round holes are opened on the two branch pipes as flushing ports. The flushing ports face downwards. A bell mouth is welded at the flushing port. The bell mouth communicates with the arc plate of the shell, but does not extend out of the inner surface of the arc plate. The powder and slag in the mixed oil are left on the separation plate. Several bell mouths face the upper part of the inclined separation plate and flush the surface of the separation plate from above. The flushed powder and slag enter the slag collection port and fall into the slag discharge chamber. The slag discharge chamber is a chute shape that is larger at the top and smaller at the bottom, collecting the powder and slag into the slag discharge pipe assembly 36.
