Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a solid-liquid separation centrifuge for wastewater treatment and its usage method. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids and liquids. The magnitude of the centrifugal force is determined by the rotation speed, the radius of rotation, and the mass of the substance. Centrifuges are widely used in chemical engineering, petroleum, food processing, pharmaceuticals, mineral processing, carbon, water treatment, nuclear energy, and shipbuilding. The main principle of a filter centrifuge is that the centrifugal force generated by the high-speed rotating centrifugal drum (with appropriate filter media) accelerates the liquid phase of a solid-liquid mixture out of the drum, while the solid phase remains inside, achieving the effect of separating solids and liquids, or dehydration.

[0003] Existing solid-liquid separation centrifuges for wastewater treatment have the following problems during use: By rotating the separation tube, the liquid portion of the wastewater inside the separation tube is thrown out through the separation holes on it, achieving the effect of solid-liquid separation. However, existing separators do not have the function of cleaning the separation tube, which leads to blockage at the separation holes on the separation tube, affecting the efficiency of solid-liquid separation.

[0004] To avoid the aforementioned problems, Chinese Patent CN219664016U discloses a solid-liquid separation centrifuge for wastewater treatment, relating to the field of wastewater treatment technology. It includes a housing, an inlet pipe, and a controller. The controller is mounted on the housing, and the inlet pipe is inserted into the housing and a separation tube, both of which are rotatable relative to each other. The separation tube is mounted on the housing and is also rotatable relative to the housing. Several evenly distributed separation holes are provided on the side wall of the separation tube. It also includes a separation base located on the upper side of a mounting plate and connected to a separation motor. This utility model provides a solid-liquid separation centrifuge for wastewater treatment. Through the cooperation of components such as the cleaning assembly, the inner wall of the separation tube can be cleaned. Simultaneously, clean water can be introduced into the separation tube from the top inlet pipe, flushing away dirt clogging the separation holes and preventing blockage, thus ensuring the solid-liquid separation performance of the separation tube.

[0005] While the above methods can flush the inside of the separation tube to prevent the separation holes from becoming clogged and ensure the solid-liquid separation performance of the separation tube, there are still some shortcomings in actual use. For example, the device lacks an integrated cleaning and unclogging mechanism, which makes the removal of solid impurities and unclogging of the mesh inside the separation tube cumbersome and inconvenient. To avoid such problems, a solid-liquid separation centrifuge for wastewater treatment and its usage method are proposed to solve the existing problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a solid-liquid separation centrifuge for wastewater treatment and its usage method, solving the problem that the lack of an integrated material cleaning and unclogging mechanism in the device leads to cumbersome and inconvenient removal of solid impurities inside the separation tube and unclogging of the mesh.

A lifting frame is fixedly connected to the top of the threaded sleeve. One end of the lifting frame extends into the interior of the centrifugal filter frame, and a material ejector plate is rotatably connected to the end of the lifting frame extending into the centrifugal filter frame via a bearing. An annular sliding frame is fixedly connected to the outer wall of the threaded sleeve via a bracket. A compression ring, matching the bent rods, is slidably connected inside the annular sliding frame. A driving mechanism is provided between the reciprocating screw and the rotating shaft.

[0009] Preferably, the unloading mechanism includes a rotating rod, which is rotatably mounted on the top of the support plate via a bearing. Both the surface of the rotating rod and the surface of the reciprocating screw are fixedly connected to pulleys, and a belt drives between the two pulleys. One end of the rotating rod passes through and extends to the top of the partition plate. A feeding plate, matching the unloading plate, is fixedly connected to the end of the rotating rod extending to the top of the partition plate. A feeding inclined frame, matching the feeding plate, is provided on the top of the partition plate.

[0010] Preferably, the acceleration mechanism includes a sliding sleeve, which is fixedly disposed on the side of the inner cavity of the processing box. A telescopic column is slidably connected inside the sliding sleeve, and the top of the telescopic column is fixedly connected to the bottom of the feeding inclined frame through a bracket. A second return spring is fixedly connected between the telescopic column and the sliding sleeve. A cam that matches the feeding inclined frame is fixedly connected to the surface of the rotating rod and located at the top of the partition.

[0011] Preferably, the device includes a mounting ring, which is rotatably mounted on one side of the processing chamber cavity via a damping bearing, and the mounting ring is centered with the rotating shaft. A plurality of mounting boxes are fixedly connected in an equidistant array around the inner wall of the mounting ring. A movable plate is slidably connected inside each mounting box. A third return spring is fixedly connected between the movable plate and the mounting box. A shaped retaining plate matching the movable plate is fixedly connected to the surface of the rotating shaft and inside the mounting ring. A first gear is fixedly connected to the outer surface of the mounting ring, and a second gear meshing with the first gear is fixedly connected to the surface of the reciprocating screw.

[0012] Preferably, a limiting groove is provided at the top of the partition, and a limiting slider is slidably connected inside the limiting groove. The top of the limiting slider is fixedly connected to the bottom of the feeding inclined frame.

[0013] Preferably, a mounting sleeve is fixedly connected to the top and bottom of one side of the bending rod, a telescopic block is slidably connected inside the mounting sleeve, and one side of the telescopic block is fixedly connected to the outer surface of the centrifugal filter frame. A first return spring is fixedly connected between adjacent telescopic blocks and mounting sleeves.

[0014] Preferably, a roller is provided on one side of the movable plate through a slot.

[0015] This invention also discloses a solid-liquid separation method for wastewater treatment, specifically including the following steps:

[0016] S1. During normal solid-liquid separation, the drive motor starts in the forward direction. The drive motor drives the rotating shaft and the large gear to rotate. The large gear rotates and meshes with the small gear. The meshing and rotation of the small gear causes the centrifugal filter frame to rotate at high speed. The centrifugal rotation of the centrifugal filter frame will throw out the water in the solid impurities inside the centrifugal filter frame.

[0017] S2. When solid impurities are being removed from the centrifugal filter frame, the drive motor is started in reverse. The drive motor drives the rotating shaft to rotate in reverse, which in turn drives the shaped clamping plate to rotate in reverse. The shaped clamping plate rotates in reverse and forms a limiting engagement with the movable plate. Simultaneously, the movable plate drives the mounting ring and the first gear to rotate. The rotation of the first gear meshes with the second gear. The meshing of the second gear drives the reciprocating screw to rotate. The rotation of the reciprocating screw and the threaded sleeve on its surface drive the lifting frame to move up and down reciprocally. The lifting frame rises and drives the unloading plate to gradually rise from inside the centrifugal filter frame.

[0018] During the upward movement of the threaded sleeve, the lifting frame and the ejector plate rise simultaneously. The threaded sleeve also drives the annular slide frame to rise through the bracket. The annular slide frame drives the extrusion ring to rise. As the extrusion ring rises, it gradually extrudes multiple bent rods. The extrusion of the bent rods causes the unblocking rods to engage with the filter holes on the outer surface of the centrifugal filter frame. Through the push of the unblocking rods, the impurities remaining inside the filter holes are forced to return to the interior of the centrifugal filter frame and are then pushed out by the ejector plate.

[0019] S3. During the rotation of the reciprocating screw, the reciprocating screw will also drive the pulley to rotate. The pulley is synchronously engaged with the belt drive and drives the rotating rod to rotate synchronously through the drive engagement. The rotation of the rotating rod drives the feeding plate to rotate at high speed. Along with the ejection plate, the solid impurities are lifted to the top of the centrifugal filter frame. The feeding plate guides the impurities higher than the top of the centrifugal filter frame to the top of the discharge inclined frame and out of the processing box through the inclined surface of the discharge inclined frame.

[0020] S4. During the rotation of the rotating rod, the rotating rod synchronously drives the cam to rotate. When the cam rotates, its protrusion squeezes the feeding inclined frame to move to the right. When the corresponding protrusion leaves the feeding inclined frame, the feeding inclined frame slides back to its original position through the elastic cooperation of the telescopic column and the second reset spring. The feeding inclined frame reciprocates and screens, which makes it easier for the dehydrated impurities to fall from the feeding inclined frame to the outside of the processing box.

[0021] Preferably, in S1, the bottom of the centrifugal filter frame is fixedly connected to an annular slide plate, and several slides are equidistantly arranged around the annular slide plate, with the bottom of the slides fixedly connected to the bottom of the inner cavity of the processing box.

[0022] This invention provides a solid-liquid separation centrifuge for wastewater treatment and its method of use. Compared with existing technologies, it has the following advantages:

[0023] (1) The solid-liquid separation centrifuge for sewage treatment and its usage method, by setting a unclogging mechanism, a material discharge mechanism and an acceleration mechanism between the treatment box and the centrifugal filter frame, enables the centrifugal filter frame to autonomously complete the unclogging of the filter holes and the discharge of solid impurities through the synchronous coordination of the unclogging mechanism, the material discharge mechanism and the acceleration mechanism when solid impurities need to be discharged, and simultaneously accelerates the shaking off of the discharged solid impurities, thereby improving the rate and smoothness of solid impurity discharge.

[0024] (2) The solid-liquid separation centrifuge for sewage treatment and its method of use, by sliding a compression ring inside the annular slide frame and matching it with the bending rod, the compression ring can not only cooperate with the annular compression of the bending rod, but also cooperate with the rotation of the annular slide frame, so that the bending rod can carry the compression ring to rotate synchronously, thus avoiding hard friction between the bending rod and the compression ring.

[0025] (3) The solid-liquid separation centrifuge for sewage treatment and its usage method, by rotating and setting a roller on one side of the movable plate, so that during the forward frictional engagement between the movable plate and the irregular plate, the roller can reduce the frictional resistance between the movable plate and the irregular plate and reduce the friction coefficient.

[0026] (4) The solid-liquid separation centrifuge for sewage treatment and its usage method, by rotating the lifting frame and the discharge plate together, the discharge plate can be centrifugally rotated together with the centrifugal filter frame, so as to better separate solid impurities from water and centrifuge them out.

[0049] As a detailed explanation: To facilitate the removal of solid impurities after dehydration, a material removal mechanism 6 is provided between the unblocking mechanism 5 and the processing box 1. The material removal mechanism 6 includes a rotating rod 601, which is rotatably mounted on the top of the support plate 4 via bearings.

[0052] Compared with Example 1, Example 2 has the advantage that by rotating and setting the roller 17 on one side of the movable plate 5093, the roller 17 can reduce the frictional resistance between the movable plate 5093 and the irregular clamping plate 5095 and reduce the coefficient of friction during the forward rotation frictional engagement of the movable plate 5093 and the irregular clamping plate 5095.

[0053] This invention also discloses a solid-liquid separation method for wastewater treatment, specifically including the following steps:

[0054] S1. During normal solid-liquid separation, the drive motor 8 starts rotating in the forward direction. The drive motor 8 drives the rotating shaft 9 and the large gear 10 to rotate. The large gear 10 rotates and meshes with the small gear 11. The meshing and rotation of the small gear 11 causes the centrifugal filter frame 3 to rotate at high speed. The centrifugal rotation of the centrifugal filter frame 3 will throw out the water in the solid impurities inside the centrifugal filter frame 3. The bottom of the centrifugal filter frame 3 is fixedly connected to an annular slide plate, and several slides are equidistantly arranged around the annular slide plate. The bottom of the slides is fixedly connected to the bottom of the inner cavity of the processing box 1.

[0055] S2. When solid impurities are being removed from the centrifugal filter frame 3, the drive motor 8 is started in reverse. The drive motor 8 drives the rotating shaft 9 to rotate in reverse. The rotating shaft 9 drives the irregularly shaped clamping plate 5095 to rotate in reverse. The irregularly shaped clamping plate 5095 will form a limiting engagement with the movable plate 5093, and simultaneously drive the mounting ring 5091 and the first gear 5096 to rotate through the movable plate 5093. The rotation of the first gear 5096 will mesh with the second gear 5097. The meshing of the second gear 5097 will drive the reciprocating screw 503 to rotate. The rotation of the reciprocating screw 503 will drive the lifting frame 505 to move up and down reciprocally. The rise of the lifting frame 505 will drive the unloading plate 506 to gradually rise from inside the centrifugal filter frame 3.

[0056] During the upward movement of the threaded sleeve 504, the lifting frame 505 and the ejector plate 506 are simultaneously driven upward by the threaded sleeve 504 through the bracket. The annular slide frame 507 is driven upward by the annular slide frame 507. The extrusion ring 508 is driven upward by the extrusion ring 508. The extrusion ring 508 will gradually extrude multiple bent rods 501. The extrusion of the bent rods 501 will cause the unblocking rod 502 to fit into the filter holes on the outer surface of the centrifugal filter frame 3. Through the push of the unblocking rod 502, the impurities remaining inside the filter holes will return to the interior of the centrifugal filter frame 3 and be pushed out by the ejector plate 506.

[0057] S3. During the rotation of the reciprocating screw 503, the reciprocating screw 503 will also drive the pulley 602 to rotate. The pulley 602 is synchronously connected with the belt 603 for transmission and synchronously drives the rotating rod 601 to rotate. The rotation of the rotating rod 601 drives the feeding plate 604 to rotate at high speed. Accompanied by the ejection plate 506 lifting solid impurities to the top of the centrifugal filter frame 3, the feeding plate 604 guides the impurities higher than the top of the centrifugal filter frame 3 to the top of the discharge inclined frame 605 and discharges them to the outside of the processing box 1 through the inclined surface of the discharge inclined frame 605.

[0058] S4. During the rotation of the rotating rod 601, the rotating rod 601 synchronously drives the cam 704 to rotate. The cam 704 rotates and its protrusion squeezes the feeding inclined frame 605 to move to the right. When the corresponding protrusion leaves the feeding inclined frame 605, the feeding inclined frame 605 slides back to its original position through the elastic cooperation of the telescopic column 702 and the second return spring 703. The feeding inclined frame 605 reciprocates and screens, so that the dehydrated impurities can easily fall from the feeding inclined frame 605 to the outside of the processing box 1.

6. A solid-liquid separation centrifuge for wastewater treatment according to claim 3, characterized in that: One side of the movable plate (5093) is provided with a roller (17) through a slot.

7. A solid-liquid separation method for wastewater treatment, employing the centrifuge as described in claim 6, characterized in that: Specifically, the following steps are included: S1. During normal solid-liquid separation, the drive motor (8) is started in the forward direction. The drive motor (8) drives the rotating shaft (9) and the large gear (10) to rotate. The large gear (10) rotates and meshes with the small gear (11). Through the meshing and rotation of the small gear (11), the centrifugal filter frame (3) is driven to rotate at high speed. The centrifugal rotation of the centrifugal filter frame (3) will throw out the water in the solid impurities inside the centrifugal filter frame (3). S2. When solid impurities are removed from the centrifugal filter frame (3), the drive motor (8) is started in reverse. The drive motor (8) drives the rotating shaft (9) to reverse. The rotating shaft (9) drives the irregular plate (5095) to reverse. The irregular plate (5095) will form a limiting fit with the movable plate (5093) in reverse, and simultaneously drive the mounting ring (5091) and the first gear (5096) to rotate through the movable plate (5093). The rotation of the first gear (5096) will mesh with the second gear (5097). The meshing of the second gear (5097) will drive the reciprocating screw (503) to rotate. The rotation of the reciprocating screw (503) and the threaded sleeve (504) on its surface will drive the lifting frame (505) to move up and down reciprocally. The lifting frame (505) rises and drives the unloading plate (506) to gradually rise from inside the centrifugal filter frame (3). During the upward movement of the threaded sleeve (504) driving the lifting frame (505) and the ejector plate (506), the threaded sleeve (504) simultaneously drives the annular slide frame (507) to rise through the bracket. The annular slide frame (507) drives the extrusion ring (508) to rise. The rising extrusion ring (508) will gradually extrude multiple bent rods (501). The extrusion of the bent rods (501) will cause the unblocking rod (502) to fit into the filter holes on the outer surface of the centrifugal filter frame (3). Through the push of the unblocking rod (502), the impurities remaining inside the filter holes will return to the interior of the centrifugal filter frame (3) and be pushed out by the subsequent ejector plate (506). S3. During the rotation of the reciprocating screw (503), the reciprocating screw (503) will also drive the pulley (602) to rotate. The pulley (602) is synchronously driven by the belt (603) and drives the rotating rod (601) to rotate synchronously through the transmission. The rotation of the rotating rod (601) drives the feeding plate (604) to rotate at high speed. Accompanied by the ejection plate (506) lifting solid impurities to the top of the centrifugal filter frame (3), the feeding plate (604) guides the impurities higher than the top of the centrifugal filter frame (3) to the top of the discharge inclined frame (605) and discharges them to the outside of the processing box (1) through the inclined surface of the discharge inclined frame (605). S4. During the rotation of the rotating rod (601), the rotating rod (601) synchronously drives the cam (704) to rotate. The cam (704) rotates and its protrusion squeezes the feeding inclined frame (605) to move to the right. When the corresponding protrusion leaves the feeding inclined frame (605), the feeding inclined frame (605) slides back through the elastic cooperation of the telescopic column (702) and the second reset spring (703). The feeding inclined frame (605) reciprocates and screens, so that the dehydrated impurities can fall from the feeding inclined frame (605) to the outside of the processing box (1).

8. A solid-liquid separation method for wastewater treatment according to claim 7, characterized in that: The bottom of the centrifugal filter frame (3) in S1 is fixedly connected to an annular slide plate, and several slides are equidistantly arranged around the annular slide plate, and the bottom of the slides is fixedly connected to the bottom of the inner cavity of the processing box (1).
