Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a high-efficiency treatment device for recycling waste vegetable oil wastewater. Background Art

[0002] In the production process of vegetable oil, during the extraction process of vegetable oil, such as after producing vegetable oil by pressing method or leaching method, the equipment needs to be cleaned with water. Since the equipment contains residual waste vegetable oil, waste vegetable oil wastewater is generated after the equipment is cleaned. Because the waste vegetable oil wastewater contains sediment, when recycling the waste vegetable oil wastewater, the wastewater needs to be treated to separate the sediment in the waste vegetable oil from the wastewater. The existing technology intercepts the sediment in the waste vegetable oil wastewater through a filtering device to separate the sediment in the waste vegetable oil wastewater, and then stops treating the waste vegetable oil wastewater every once in a while to clean the sediment in the filtering device. However, the existing technology can only realize the separation and treatment of the oil-water and sediment in the waste vegetable oil wastewater. In addition to sediment in the waste vegetable oil wastewater, there are also residual waste vegetable oil and cleaning water. Since waste vegetable oil has a high recycling value, the existing technology cannot simultaneously treat and separate waste vegetable oil, cleaning water and sediment, resulting in certain economic losses. Summary of the Invention

[0004] It includes a conveying pipeline and a treatment device. The treatment device includes a treatment mechanism and a cleaning water collection pool, a waste vegetable oil collection pool and a sediment collection pool arranged side by side from left to right on one side of the treatment mechanism. The conveying pipeline is located on one side of the treatment mechanism. A gantry is provided on the waste vegetable oil collection pool, and a cross beam is provided on the gantry. The left and right end faces of the cross beam are beveled surfaces.

[0005] Further, the treatment mechanism includes a fixing frame. A fixing platform is arranged inside the fixing frame. A driving member is arranged on the fixing platform.

[0007] Further, the guiding assembly includes a set of guide rails disposed on the fixed frame, and a set of guard plates are arranged on the guide rails. A chute is formed in one of the guard plates, and an arc-shaped plate is arranged on the guard plate. A spiral groove is formed in the inner wall of the arc-shaped plate, and the spiral groove is communicated with the chute. A sliding plate is slidably connected in the guide rail, a fixed rod is arranged at the bottom of the sliding plate, a second connecting rod is rotatably connected to the fixed rod, a set of vertical plates are arranged on the sliding plate, a bearing is embedded in each vertical plate, a push rod is connected in the bearing, a fixed sleeve is arranged on the push rod, a limiting rod is arranged on the fixed sleeve, the end of the limiting rod is a circular surface, the limiting rod is located in the chute, and a separating assembly is arranged at the end of the push rod.

[0008] Further, the separating assembly includes a cleaning water separating cylinder arranged on the push rod. The upper and lower parts of the cleaning water separating cylinder are both open structures. A waste vegetable oil separating cylinder is arranged at the bottom of the cleaning water separating cylinder. The diameter of the filter holes on the cleaning water separating cylinder is smaller than the diameter of the filter holes on the waste vegetable oil separating cylinder.

The cross beam 6 is fixed on the gantry 5. The left and right end faces of the cross beam 6 are beveled surfaces.

[0021] Please refer to Figure 2 , the treatment mechanism includes a fixing frame 7. A fixing platform 8 is arranged inside the fixing frame 7. The fixing platform 8 is fixed on the fixing frame 7. A driving member is arranged on the fixing platform 8. A pushing member is arranged on the fixing frame 7. The driving member is connected to the pushing member. The driving member drives the pushing member to move horizontally left and right. The pushing member includes a guiding component and a separation component. The separation component is located above the cleaning water collection tank 3.

[0022] The driving member includes a motor 9 disposed on the fixed table 8. A first connecting rod 10 is provided on the output shaft of the motor 9. The first connecting rod 10 is fixed to the output shaft of the motor 9. The motor 9 drives the first connecting rod 10 to rotate. A second connecting rod 11 is hinged to the first connecting rod 10. The first connecting rod 10 drives the second connecting rod 11 and enables the second connecting rod 11 to drive the guiding assembly to move horizontally left and right.

[0023] Please refer to Figures 3 - 5 , the guiding assembly includes a set of guide rails 12 disposed on the fixed frame 7. A set of guard plates 13 are provided on the guide rails 12. A chute 14 is formed in one of the guard plates 13. An arc-shaped plate 15 is provided on the guard plate 13. A spiral groove 16 is formed in the inner wall of the arc-shaped plate 15. The spiral groove 16 communicates with the chute 14. A sliding plate 17 is slidably connected in the guide rail 12. The second connecting rod 11 drives the sliding plate 17 to slide left and right in the guide rail 12. A fixing rod 18 is provided at the bottom of the sliding plate 17. The second connecting rod 11 is rotatably connected to the fixing rod 18. A set of vertical plates 19 are provided on the sliding plate 17. Each vertical plate 19 is embedded with a bearing 20. A push rod 21 is connected in the bearing 20. A fixing sleeve 22 is provided on the push rod 21. A limiting rod 23 is provided on the fixing sleeve 22. The end of the limiting rod 23 is a circular surface. The limiting rod 23 is located in the chute 14. The sliding plate 17 drives the vertical plates 19 and the push rod 21 to move horizontally left and right. The push rod 21 drives the limiting rod 23 to first move horizontally in the chute 14. When it moves to the intersection of the chute 14 and the spiral groove 16, the limiting rod 23 enters the spiral groove 16 and drives the push rod 21 to rotate 180° while moving horizontally along the semi-circular path of the spiral groove 16. A separating assembly is provided at the end of the push rod 21.

[0024] Please refer to Figures 6 - 7, the separation component includes a cleaning water separation cylinder 24 provided on the push rod 21. Both the upper and lower parts of the cleaning water separation cylinder 24 are open structures. The cleaning water separation cylinder 24 is formed by rolling and welding a super-hydrophilic and super-oleophobic stainless steel filter mesh. The super-hydrophilic and super-oleophobic stainless steel filter mesh has a strong affinity for water, and water can quickly spread and penetrate on its surface, while having a strong repellency to oil, making oil unable to pass through. The waste vegetable oil wastewater first enters the cleaning water separation cylinder 24 through the conveying pipeline 1. The cleaning water separation cylinder 24 is used to separate the cleaning water. A waste vegetable oil separation cylinder 25 is provided at the bottom of the cleaning water separation cylinder 24. The waste vegetable oil separation cylinder 25 is used to separate the waste vegetable oil. The pore diameter of the filter holes on the cleaning water separation cylinder 24 is smaller than the pore diameter of the filter holes on the waste vegetable oil separation cylinder 25. The waste vegetable oil separation cylinder 25 is formed by rolling and welding an ordinary stainless steel filter mesh. Therefore, the waste vegetable oil can directly pass through the filter holes of the waste vegetable oil separation cylinder 25 and be discharged directly. The upper part of the waste vegetable oil separation cylinder 25 is an open structure and the bottom is a closed structure. A sealing plate 26 is movably provided at the bottom of the cleaning water separation cylinder 24. A spring column 27 is provided on the upper side of the sealing plate 26. The sealing plate 26 moves up and down between the bottom of the cleaning separation cylinder 24 and the inside of the waste vegetable oil separation cylinder 25 due to the expansion and contraction of the spring column 27. The sealing plate 26 seals the bottom of the cleaning water separation cylinder 24. The lower telescopic end of the spring column 27 is connected to the sealing plate 26. A triangular body 28 is provided at the upper telescopic end of the spring column 27. A connecting rod 29 is provided on the inner wall of the cleaning water separation cylinder 24, and the connecting rod 29 is fixed to the spring column 27.

[0025] Working principle of the present invention: Waste vegetable oil wastewater enters the cleaning water separation cylinder 24 through the conveying pipeline 1. The cleaning water, waste vegetable oil, and sediment in the waste vegetable oil wastewater remain in the cleaning water separation cylinder 24. Among them, the cleaning water falls into the cleaning water collection pool 2 through the cleaning water separation cylinder 24, while the waste vegetable oil and sediment cannot pass through the cleaning water separation cylinder 24 and remain in the cleaning water separation cylinder 24. Every once in a while, the conveying pipeline 1 is closed to stop the conveyance of waste vegetable oil wastewater. At the same time, the motor 9 is started. The motor drives the first connecting rod 10 to rotate slowly. The first connecting rod 10 drives the second connecting rod 11. The second connecting rod 11 rotates and drives the slide plate 17 to slowly move to the right in the guide rail 12. The slide plate 17 drives the vertical plate 19 and the push rod 21 to move to the right. The push rod 21 drives the entire separation assembly to move to the right. The push rod 21 also drives the limit rod 23 to move horizontally to the right in the chute 14. When the separation assembly moves above the waste vegetable oil collection pool 3, the right inclined surface of the triangular body 28 is in sliding contact with the inclined cut surface at the left end of the cross beam 6. Limited by the cross beam 6, the triangular body 28 moves downward. At the same time, the upper telescopic end of the spring column 27 driven by the triangular body 28 descends. The upper telescopic end of the spring column 27 drives the lower telescopic end of the spring column 27 to descend. The lower telescopic end of the spring column 27 drives the sealing plate 26 to descend, so that the sealing plate 26 descends into the interior of the waste vegetable oil separation cylinder 25 until the top of the triangular body 28 is in sliding contact with the bottom of the cross beam 6. The triangular body 28 stops descending and continues to move to the right under the drive of the push rod 21. The waste vegetable oil and sediment in the cleaning water separation cylinder 24 settle into the waste vegetable oil separation cylinder 25 along with the settlement of the sealing plate 26. The waste vegetable oil in the waste vegetable oil separation cylinder 25 falls into the waste vegetable oil collection pool 3 through the filter holes on the waste vegetable oil separation cylinder 25, while the sediment is intercepted and remains in the waste vegetable oil separation cylinder 25. When the triangular body 28 disengages from the cross beam 6, the spring column 27 rebounds. The lower telescopic end of the spring column 27 drives the sealing plate 26 to rise. The sealing plate 26 drives the sediment on its upper part to be lifted together. The sediment returns to the cleaning water separation cylinder 24. When the limit rod 23 just reaches the spiral groove 16 position from the chute 14, the entire separation assembly just reaches directly above the sediment collection pool 4. When the limit rod 23 enters the spiral groove 16, limited by the semicircular trajectory of the entire spiral groove 16, the limit rod 23 moves to the right and rotates a semicircular stroke in the spiral groove 16. The limit rod 23 drives the fixed sleeve 22, and the fixed sleeve 22 drives the push rod 21 to rotate 180 degrees in the bearing 20, so that the cleaning water separation cylinder 24 and the waste vegetable oil separation cylinder 25 are flipped 180°. The sediment in the cleaning water separation cylinder 24 is poured into the sediment collection pool 4. At this time, the motor 9 drives the first connecting rod 10 to rotate exactly a semicircular stroke. When the motor 9 drives the first connecting rod 10 to rotate the remaining semicircular stroke, the limit rod 23 returns along the original path in the spiral groove 16, and the cleaning water separation cylinder 24 and the waste vegetable oil separation cylinder 25 rotate back to the original position. Then, under the drive of the push rod 21, it returns to the right along the original path. When the motor 9 drives the first connecting rod 10 to rotate a whole circular stroke, the entire separation assembly just returns to the initial position.Then the conveying pipeline 1 is opened to continue conveying the waste vegetable oil wastewater into the cleaning water separation cylinder 24.,

[0026] The operation of the present invention is simple and convenient to use, and is suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
