Description

Technical Field

[0001] This utility model relates to the field of oil sludge separation technology, specifically to an oil sludge centrifugal separation device. Background Technology

[0002] Oil sludge is an oil-containing solid waste generated during oil extraction, storage, transportation, refining, and machining processes. It typically consists of oil, water, and solid particles. Direct discharge or improper disposal can cause serious pollution to soil and water bodies. Horizontal screw centrifuges are commonly used equipment for separating oil sludge. They utilize centrifugal force through the high-speed rotation of the drum to separate oil, water, and solids. The solid material deposits on the inner wall of the drum and is then pushed to the discharge port by a screw conveyor.

[0003] However, in actual operation, due to the high viscosity of sludge, the small size of solid particles and their easy adhesion, solid materials often adhere and accumulate on the inner wall of the drum discharge port and the machine base discharge chamber. The solid material located at the top of the inner side of the discharge chamber lacks the downward pressure and pushing of the discharged material, and a solidified layer is easily formed here after long-term operation. This not only affects the discharge efficiency, but also causes equipment blockage and cleaning difficulties. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an oil sludge centrifugal separation device to solve the issue that the solid material at the top of the discharge chamber of the machine base lacks the force to push it out, and is prone to solidification and blockage at this location.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an oil sludge centrifugal separation device, including a base and a drum, and further including a reciprocating mechanism, a buffer mechanism, a push rod, a push plate and a scraper. The drum is rotatably installed inside the base, the reciprocating mechanism is located on the front side of the base, the buffer mechanism is located on the front side of the base and connected to the moving end of the reciprocating mechanism, the push rod is slidably installed on the surface of the base and connected to the buffer mechanism, the push plate is rotatably installed on one end of the push rod, and the scraper is slidably installed inside the base and fits against the inner wall of the base and the top front surface of the drum.

[0006] The machine base has a solid discharge chamber on its front side and a solid discharge port at the front end of the drum. The discharge port of the drum is located in the discharge chamber of the machine base, and the scraper is attached to the inner wall of the discharge chamber of the machine base.

[0007] The reciprocating mechanism includes a motor, a sliding sleeve, a reciprocating lead screw, and a slider. The motor is fixedly installed on the front side of the machine base, the sliding sleeve is fixedly installed on the front side of the machine base, the reciprocating lead screw is rotatably installed inside the sliding sleeve, and the slider is threadedly installed on the surface of the reciprocating lead screw.

[0008] The buffer mechanism includes a slide rod, a connecting block, a spring, and a U-shaped plate. The slide rod is fixedly installed on the front side of the machine base. The connecting block is slidably sleeved on the surface of the slide rod. The U-shaped plate is fixedly installed on the rear side of the moving end of the reciprocating mechanism, and the rear end of the U-shaped plate is slidably sleeved on the surface of the slide rod. One end of the spring is connected to the connecting block, and the other end is connected to the U-shaped plate.

[0009] The push rod includes a rod body, a sliding plate, a screw, and a rack. The rod body is slidably inserted into the surface of the base. The sliding plate is slidably installed inside the rod body. The screw is threadedly installed at the end of the rod body away from the scraper, and the screw is rotatably connected to one end of the sliding plate. The rack is fixedly installed at the other end of the sliding plate.

[0010] The push rod also includes a bidirectional lead screw, a limiting plate, a gear, and a connecting frame. The bidirectional lead screw is rotatably installed inside the rod body, the limiting plate is threaded onto the surface of the bidirectional lead screw, the gear is fixedly sleeved in the middle of the bidirectional lead screw, and the gear is meshed with the rack. The connecting frame is fixedly installed at the end of the rod body away from the scraper.

[0011] The push plate includes a plate body, a rotating shaft, and a limiting post. The rotating shaft is rotatably installed on one end of the rod body near the scraper. The plate body is fixedly installed on one side of the rotating shaft, and the plate body is in contact with the surface of the scraper. The limiting post is fixedly installed on the other side of the rotating shaft.

[0012] The scraping component includes a scraper and a guide bar. The scraper is slidably installed inside the machine base, and the guide bar is fixedly installed on the top of the scraper.

[0013] The beneficial effects of this utility model are as follows: This invention uses a motor to drive a reciprocating lead screw, which in turn causes a slider to slide back and forth inside a sliding sleeve. The slider causes a U-shaped plate to slide along the surface of the slide rod, compressing and stretching two sets of springs respectively. Through the transmission of the springs, the connecting block slides along the surface of the slide rod. The connecting block drives the connecting frame to move, which in turn causes the rod body to press the plate at its end against the surface of the scraper. With the assistance of the guide strip, the scraper pushes the solid material that is stuck and accumulated above the solid discharge chamber of the machine base to the left and right sides, promoting its discharge. This prevents the separated solid phase from accumulating in the discharge chamber above the drum, where it can remain and solidify for a long time, making it difficult to clean and discharge later. By turning the screw... The rod drives the sliding plate to slide inside the rod body, causing the sliding plate to drive the rack to move. Through the meshing transmission of the rack and gear, the double-acting screw rotates, thereby controlling the two sets of limiting plates to move in opposite directions, changing the distance between the two sets of limiting plates, limiting the movement range of the limiting post, and thus controlling the extreme value of the rotation angle of the plate body. When the plate body pushes the scraper to slide in the solid phase discharge cavity of the machine base, the rotation limit of the plate body is reached. Continuing to push the plate body will only reduce the contact area between the originally completely fitted plate body and the scraper, and the thrust is insufficient to push the scraper to continue rotating. At the same time, the plate body on the other side restricts the scraper from continuing to slide along the solid phase discharge cavity of the machine base, thereby achieving the effect of controlling the sliding range of the scraper in the solid phase discharge cavity of the machine base.

The scraper 7 is slidably installed inside the base 1 and is in contact with the inner wall of the base 1 and the top front surface of the drum 2. Specifically, the drum 2 is supported by the base 1 and rotates stably inside it. The reciprocating mechanism 3 pushes the buffer mechanism 4 to reciprocate to the left and right sides. The buffer mechanism 4 drives the push rod 5 to slide on the surface of the base 1. The push rod 5 pushes the push plate 6, so that the rotating push plate 6 is in contact with the surface of the scraper 7. The push plate 6 pushes the scraper 7 to slide inside the base 1, pushing down the accumulated solid material.

The discharge port of the drum 2 is located at the discharge chamber of the machine base 1, and the scraper 7 is attached to the inner wall of the discharge chamber of the machine base 1. Specifically, the solid material is discharged from the solid discharge port of the drum 2 through the solid discharge chamber of the base 1 and then falls out to the outside.

[0020] The reciprocating mechanism 3 includes a motor 301, a sliding sleeve 302, a reciprocating lead screw 303, and a slider 304. The motor 301 is fixedly installed on the front side of the machine base 1, and the sliding sleeve 302 is fixedly installed on the front side of the machine base 1. A transmission gear set is provided inside one end of the sliding sleeve 302, and the output end of the motor 301 passes through one end of the sliding sleeve 302 and is connected to the transmission gear set. The reciprocating lead screw 303 is rotatably installed inside the sliding sleeve 302, and one end of the reciprocating lead screw 303 is connected to the transmission gear set of the sliding sleeve 302. The slider 304 is threaded onto the surface of the reciprocating lead screw 303, and the slider 304 is in contact with the inner wall of the sliding sleeve 302. Specifically, the motor 301 drives the reciprocating screw 303 to rotate inside the sliding sleeve 302, and the rotation of the reciprocating screw 303 drives the slider 304 to slide inside the sliding sleeve 302.

[0021] The buffer mechanism 4 includes a slide rod 401, a connecting block 402, a spring 403, and a U-shaped plate 404. The slide rod 401 is fixedly installed on the front side of the base 1. The connecting block 402 is slidably sleeved on the surface of the slide rod 401.

The two sets of connecting blocks 402 and springs 403 are sleeved on the surface of the slide rod 401 and are arranged symmetrically. Specifically, the slider 304 drives the U-shaped plate 404 to move on the surface of the slide bar 401, which compresses or stretches the spring 403, thereby pushing the connecting block 402 to slide on the surface of the slide bar 401, so that the connecting block 402 drives the connecting frame 508 to move horizontally.

[0022] The push rod 5 includes a rod body 501, a slide plate 502, a screw 503, and a rack 504.

The rack 504 is fixedly installed at the other end of the slide plate 502. Specifically, by turning the screw 503 to move it axially inside the rod 501, the slide plate 502 and the rack 504 are pushed to slide inside the rod 501. The rack 504 drives the gear 507 to rotate by meshing with the gear 507.

[0023] The push rod 5 also includes a bidirectional lead screw 505, a limiting plate 506, a gear 507, and a connecting frame 508. The bidirectional lead screw 505 is rotatably installed inside the rod body 501. The limiting plate 506 is threadedly installed on the surface of the bidirectional lead screw 505.

The connecting frame 508 is fixedly installed at the end of the rod body 501 away from the scraper 7 and is fixedly connected to the connecting block 402. Specifically, the rotation of gear 507 drives the rotation of the bidirectional lead screw 505, which in turn drives two sets of limiting plates 506 to move in opposite directions within the rod body 501, thereby changing the rotational limiting range of the limiting plates 506 on the push plate 6.

[0024] The push plate 6 includes a plate body 601, a rotating shaft 602, and a limiting post 603. The rotating shaft 602 is rotatably mounted on one end of the rod body 501 near the scraper 7. The plate body 601 is fixedly mounted on one side of the rotating shaft 602, and the plate body 601 is in contact with the surface of the scraper 7. A sealing cover is fixedly mounted on one end of the rod body 501 near the scraper 7.

The limiting post 603 is fixedly mounted on the other side of the rotating shaft 602, and the limiting post 603 is located inside the rod body 501 and between two sets of limiting plates 506. Specifically, the plate 601 is made to rotate along the shaft 602 by the contact between the plate 601 and the scraper 7, and the rotation angle of the plate 601 is limited by the contact between the limiting post 603 and the limiting plate 506.

[0025] The scraper component 7 includes a scraper 701 and a guide bar 702. The scraper 701 is slidably installed inside the machine base 1, and the guide bar 702 is fixedly installed on the top of the scraper 701. The guide bar 702 is in contact with the top of the inner side of the solid phase discharge chamber of the machine base 1. Specifically, the scraper 701 is pushed to slide inside the base 1 by the pusher plate 6, and the scraper 701 is guided by the guide bar 702 to slide stably in the solid discharge chamber of the base 1, pushing down the residual solid material accumulated above the solid discharge port of the drum 2, and assisting it to discharge quickly and fully.

[0026] In summary: When using this utility model, if the operator is using a horizontal screw centrifuge to separate oil sludge, the solid sludge is discharged from the solid discharge port of the rotating drum 2. To prevent sludge from adhering and remaining on top, the motor 301 is started to drive the reciprocating screw 303 to rotate inside the sliding sleeve 302. This causes the reciprocating screw 303 to drive the slider 304 to slide back and forth inside the sliding sleeve 302. The slider 304 drives the U-shaped plate 404 connected to it to slide on the surface of the slide rod 401, which compresses and stretches the two sets of springs 403 respectively, thus connecting... Block 402 slides on the surface of slide bar 401. Block 402 drives the push rod 5 connected to it to slide on the surface of machine base 1. Relying on the plate 601 at the end of push rod 5 to adhere to the surface of scraper 701, and with the auxiliary guidance of guide bar 702, scraper 701 slides back and forth in the solid phase discharge chamber of machine base 1, pushing down the mud residue above the solid phase discharge port of drum 2, and assisting in the stable discharge process. According to the adhesion effect of solid phase, the sliding range of scraper 7 inside machine base 1 can be adjusted. The screw 503 is turned so that the slide plate 502 slides inside the rod 501, pushing the rack 504 to drive the gear 507 meshing with it to rotate. The gear 507 drives the double-acting screw 505 to rotate, and the double-acting screw 505 drives the limiting plate 506 to move in opposite directions along the inner wall of the rod 501. The distance between the two sets of limiting plates 506 is adjusted to limit the swing range of the limiting post 603 inside the rod 501, that is, the tilt angle range of the plate 601. During the sliding process of the plate 601 pushing the scraper 701, the plate 601 and the scraper 701 move in opposite directions. The scraper 701 is in close contact with the surface and rotates continuously. When the limiting post 603 contacts the limiting plate 506, the plate 601 cannot continue to rotate. If the scraper 701 wants to continue sliding, it will separate from the surface of the plate 601, reducing the contact area. The thrust is insufficient to push it to slide. The plate 601 on the other side of the scraper 701 also cannot continue to rotate, hindering the sliding of the scraper 701. This reduces the movement range of the scraper 7. The slider 304 continues to move in a certain direction, which will only compress and pull the two sets of springs 403.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
