Description

Technical Field

[0001] This utility model relates to the field of oil removal wastewater separation technology, and in particular to a centrifugal steel belt oil removal wastewater separation device. Background Technology

[0002] In a centrifugal steel belt oil-water separation device, wastewater is centrifuged through a centrifuge drum. Due to the different densities of oil, water, and solid impurities, the three can form strata under the action of centrifugal force. After stratification, the oil on the oil layer is adsorbed by the steel belt and transported to the scraper. The scraper removes the oil, thus completing the oil-water separation.

[0003] Existing centrifugal steel belt oil-water separation devices typically use a fixed drive mechanism that rotates the steel belt, preventing the adjustment of the belt height based on the oil level in the wastewater. This results in poor performance. Furthermore, during operation, when the ambient temperature is low, the oil can solidify on the steel belt or scraper, hindering oil removal and further reducing effectiveness. Therefore, we propose a centrifugal steel belt oil-water separation device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a centrifugal steel belt oil removal and wastewater separation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a centrifugal steel belt oil removal wastewater separation device is designed, including a base, a turntable rotatably connected to the top of the base, the bottom of the turntable being connected to a second drive motor, and the second drive motor being fixed to the bottom of the base, and a centrifugal cylinder being installed on the top of the turntable.

[0006] The top of the base is provided with a strip connecting plate. Both ends of the bottom of the strip connecting plate are connected to the base through a telescopic mechanism. An L-shaped mounting plate is installed on the top of the strip connecting plate. One end of the L-shaped mounting plate is rotatably connected to a drive wheel. The drive wheel is connected to a first drive motor. The first drive motor is fixed to the side of the L-shaped mounting plate. A steel belt body is fitted on the side of the drive wheel. The bottom of the steel belt body extends into the centrifuge cylinder.

[0007] The bottom of the strip connecting plate is provided with several oil guide grooves, and the top is fixed between the corresponding steel strip bodies. Two of the oil guide grooves are equipped with scrapers inside, and one end of the two scrapers is in contact with the side of the steel strip body.

[0008] A heating cover is provided on one side of the L-shaped mounting plate. The heating cover is connected to the side of the L-shaped mounting plate through a connecting mechanism, and the heating cover is fitted on the top of the drive wheel. A heating groove is provided on the inner side of the heating cover, and a heating resistance wire is installed inside the heating groove.

[0009] Preferably, the oil guide groove is inclined.

[0010] Preferably, at least one column is vertically mounted on the top of the base, and the top of the column slides through the strip connecting plate.

[0011] Preferably, the bottoms of the oil guide grooves are connected by several U-shaped frames, and the bottom of the strip connecting plate and the side of the L-shaped mounting plate are connected to the corresponding ends of the U-shaped frames.

[0012] Preferably, a material hopper is provided at one end of the oil guide trough, the top side of the material hopper is connected to one of the U-shaped frames through a connecting plate, and an oil drain pipe is connected to the bottom of the material hopper.

[0013] Preferably, the connecting mechanism includes L-shaped fixing plates symmetrically fixed on the side of the L-shaped mounting plate, and both ends of the heating cover are provided with skirts, which overlap with the corresponding L-shaped fixing plates.

[0014] Each L-shaped fixing plate has a fixing block installed on one side, and each fixing block has a U-shaped pin on the top. One end of the U-shaped pin slides through the fixing block, and each L-shaped fixing plate and the top of the skirt have through holes. The other end of the U-shaped pin passes through the corresponding through holes.

[0015] An anti-detachment ring is installed at the end of the U-shaped pin away from the through hole, and a spring is slidably sleeved at one end of the U-shaped pin. One end of the spring abuts against the bottom of the fixing block, and the other end of the spring abuts against the top of the anti-detachment ring.

[0016] Preferably, the base has several support legs installed on its bottom edge, with a control cabinet between two support legs. The top of the control cabinet is fixed to the top of the base, and the controller inside the control cabinet is connected to the telescopic mechanism, the first drive motor, the second drive motor, and the heating resistance wire via wires.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A centrifugal steel belt oil removal wastewater separation device includes a base 1, with several support legs 16 installed on the bottom edge of the base 1. A control cabinet 28 is provided between two support legs 16. The top of the control cabinet 28 is fixed to the top of the base 1. The control cabinet 28 is equipped with a controller, which is one of a control motherboard, a host, or a PLC logic controller.

[0028] like Figure 1 As shown, a turntable 18 is rotatably connected to the top of the base 1, and the bottom of the turntable 18 is connected to the second drive motor 17, which is fixed to the bottom of the base 1. A centrifuge cylinder 15 is installed on the top of the turntable 18. The second drive motor 17 is connected to the controller through wires. In actual use, the second drive motor 17 can drive the centrifuge cylinder 15 to rotate under the action of the turntable 18, and centrifuge the wastewater in the centrifuge cylinder 15 to achieve oil-water separation.

[0029] like Figure 1 and Figure 2 As shown, the top of the base 1 is provided with a strip connecting plate 4. Both ends of the bottom of the strip connecting plate 4 are connected to the base 1 through a telescopic mechanism 2. The telescopic mechanism 2 is connected to the controller through a wire. The telescopic mechanism 2 is one of an electric push rod, a cylinder or a hydraulic rod. In actual use, the height of the strip connecting plate 4 can be adjusted through the telescopic mechanism 2.

[0030] like Figure 1 and Figure 3 As shown, an L-shaped mounting plate 7 is installed on the top of the strip connecting plate 4. One end of the L-shaped mounting plate 7 is rotatably connected to a drive wheel 11. The drive wheel 11 is connected to a first drive motor 8, and the first drive motor 8 is fixed to the side of the L-shaped mounting plate 7. A steel belt body 12 is fitted on the side of the drive wheel 11. The bottom of the steel belt body 12 extends into the centrifuge drum 15. The first drive motor 8 is connected to a controller through a wire. In actual use, the operator can move the bottom of the steel belt body 12 to the wastewater oil layer inside the centrifuge drum 15 through the telescopic mechanism 2. The first drive motor 8 can drive the drive wheel 11 to rotate, which will in turn drive the steel belt body 12 to move and absorb the oil on the surface of the centrifuge drum 15.

[0031] like Figure 3 and Figure 5 As shown, the bottom of the strip connecting plate 4 is provided with several oil guide grooves 14, and the top is fixed to the corresponding steel belt body 12 located between the oil guide grooves 14. Two of the oil guide grooves 14 are equipped with scrapers 13. One end of the two scrapers 13 is in contact with the side of the steel belt body 12. The oil guide grooves 14 are inclined. In actual use, when the steel belt body 12 moves, it will generate relative displacement with the two scrapers 13. The scrapers 13 can scrape off the oil adsorbed on the steel belt body 12. The oil flows along the scrapers 13 into the oil guide grooves 14 and is transported through the oil guide grooves 14.

[0032] It should be noted that, as Figure 5 As shown, one of the oil guide grooves 14 abuts against the side of the steel belt body 12 via a guide roller. In this way, the steel belt body 12 can be limited by the guide roller and scraper 13, so that one end of the steel belt body 12 is in close contact with the drive wheel 11, and the steel belt body 12 will not slip when the drive wheel 11 rotates.

[0033] like Figure 2 and Figure 3 As shown, the bottoms of the oil guide grooves 14 are connected by several U-shaped frames 19, and the bottom of the strip connecting plate 4 and the side of the L-shaped mounting plate 7 are connected to the corresponding ends of the U-shaped frames 19. The oil guide grooves 14, the strip connecting plate 4, and the L-shaped mounting plate 7 can be fixed together by the U-shaped frames 19. In this way, when the telescopic mechanism 2 adjusts the height of the strip connecting plate 4, the oil guide grooves 14 will move synchronously with the strip connecting plate 4.

[0034] It should be noted that, as Figure 2 and Figure 3 As shown, a hopper 5 is provided below one end of the oil guide tank 14. The top side of the hopper 5 is connected to one of the U-shaped frames 19 through a connecting plate, and the bottom of the hopper 5 is connected to an oil drain pipe 3. The oil flowing along the oil guide tank 14 will fall into the hopper 5 and finally be discharged into the external collection mechanism through the oil drain pipe 3.

[0035] like Figure 3 and Figure 4 As shown, a heating cover 9 is provided on one side of the L-shaped mounting plate 7. The heating cover 9 is connected to the side of the L-shaped mounting plate 7 through a connecting mechanism. The specific structure of the connecting mechanism is as follows: the connecting mechanism includes L-shaped fixing plates 10 symmetrically fixed on the side of the L-shaped mounting plate 7, and both ends of the heating cover 9 are provided with skirts 21. The skirts 21 are stacked with the corresponding L-shaped fixing plates 10. Each L-shaped fixing plate 10 is provided with a fixing block 27 on one side. Each fixing block 27 is provided with a U-shaped pin 22 at the top. One end of the U-shaped pin 22 slides through the fixing block 27. Each L-shaped fixing plate 10 and the top of the skirt 21 are provided with a through hole 23. The other end of the U-shaped pin 22 passes through the corresponding through hole 23. Through the cooperation of the U-shaped pin 22 and the through hole 23, the skirt 21 and the L-shaped fixing plate 10 can be fixed together, so that the heating cover 9 can be fixed on the L-shaped mounting plate 7.

[0036] It should be noted that, as Figure 4 As shown, an anti-detachment ring 26 is installed at the end of the U-shaped pin 22 away from the through hole 23, and a spring 20 is slidably sleeved at one end of the U-shaped pin 22. One end of the spring 20 abuts against the bottom of the fixing block 27, and the other end of the spring 20 abuts against the top of the anti-detachment ring 26. The elastic force of the spring 20 will cause one end of the U-shaped pin 22 to be inserted into the through hole 23, so that the U-shaped pin 22 will not come out of the through hole 23 on its own.

[0037] like Figure 4 As shown, the heating cover 9 is fitted on the top of the drive wheel 11. The heating cover 9 has a heating groove 24 on its inner side. A heating resistance wire 25 is installed inside the heating groove 24. The heating resistance wire 25 is connected to the controller through a wire. In actual use, the steel strip body 12 can be heated by the heating resistance wire 25. In this way, when the steel strip body 12 absorbs oil, the oil will not solidify, thus improving the use effect.

[0038] Specifically, in use, the operator pours wastewater into the centrifuge drum 15, then controls the second drive motor 17 to operate. The second drive motor 17 drives the centrifuge drum 15 to rotate via the turntable 18, centrifuging the wastewater. This causes the oil in the wastewater to rise and accumulate in the center. Then, the operator controls the telescopic mechanism 2 to retract, causing the strip connecting plate 4 to move downwards. The strip connecting plate 4 then moves the L-shaped mounting plate 7 downwards, which in turn simultaneously drives the first drive motor 8 and the steel belt body 12 downwards. This allows the lower end of the steel belt body 12 to extend into the oil layer on the surface of the wastewater inside the centrifuge drum 15. Then, the operator controls the first drive motor 8... In operation, the first drive motor 8 drives the drive wheel 11 to rotate, which in turn drives the steel belt body 12 to rotate, drawing oil onto the steel belt body 12 and moving it to the scraper 13. The scraper 13 scrapes off the oil from the steel belt body 12, and the oil flows along the oil guide groove 14 through the scraper 13 and into the hopper 5. Finally, it is discharged through the oil drain pipe 3. During the oil separation process, the operator controls the heating resistance wire 25 to operate. The heating resistance wire 25 generates heat to heat the surface of the steel belt body 12. The steel belt body 12 heats the oil during rotation, which prevents the oil from solidifying and improves the performance.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, at least one column 6 is vertically installed on the top of the base 1. The top of the column 6 slides through the strip connecting plate 4. The column 6 can limit the strip connecting plate 4, so that the strip connecting plate 4 remains stable.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
