Abstract

This application discloses a fully automatic adsorption oil removal device and method suitable for low-floating oil wastewater, including a flow-through tank, an oil suction roller, an oil collection tank, and a squeezing roller. An oil suction roller and a drive device are installed above the flow-through tank. An oil-absorbing felt is wound around the oil suction roller, which is mounted on the drive device and can move back and forth and up and down along the surface of the floating oil wastewater in the flow-through tank, and can also rotate. A squeezing roller is fixedly installed above the oil collection tank. The squeezing roller can contact the oil suction roller and exert a squeezing action, expelling the oil absorbed by the oil-absorbing felt and causing it to fall into the oil collection tank. In this application, the oil-absorbing felt rotates with the rotation of the drive shaft, which drives the gears forward. The overall structure allows the oil-absorbing felt to rotate and move forward simultaneously on the water surface. The oil-absorbing felt contacts the floating oil in the flow-through tank in a counter-current manner, achieving sufficient adsorption. When the oil-absorbing felt moves to contact the rotating drum, they squeeze and expel the adsorbed oil in opposite directions of rotation, collecting it in the oil collection tank, ensuring timely and continuous discharge of the oil.

Description

Technical Field

[0001] This application belongs to the field of oily wastewater treatment technology, and relates to a fully automatic adsorption oil removal device and method suitable for low-floating oil wastewater. Background Technology

[0002] Low-floating oily wastewater has a wide range of sources and complex composition. When it floats on the water surface, it easily forms an oil film, causing oxygen deficiency in the water and the death of aquatic organisms. At the same time, industrial low-floating oily wastewater directly affects water quality. If it is not removed or is not removed thoroughly, it will cause certain damage and impact on downstream equipment.

[0003] Currently, the treatment method for low-floating oily wastewater involves directly placing oil-absorbing pads on the water surface, spreading them out completely, allowing them to float and absorb oil. Once saturated, the pads are retrieved and either disposed of or centrally treated. However, this method suffers from several drawbacks. First, due to water flow variations or incomplete pad installation, the pads may not completely cover the water surface, resulting in incomplete oil absorption. Second, the placement and retrieval of oil-absorbing pads are primarily manual operations, making automation and continuous operation impossible. Furthermore, directly discarding or centrally treating saturated pads leads to resource waste.

[0004] How to achieve full contact between oil-absorbing pads and floating oil, how to automate the deployment and retrieval of oil-absorbing pads, how to recycle and reuse oil-absorbing pads, and how to manufacture low-cost, high-efficiency, and automated devices or equipment are urgent problems that need to be solved. Summary of the Invention

[0005] The purpose of this application is to solve the problems in the prior art and provide a highly efficient, simple, economical, recyclable and highly automated fully automatic adsorption oil removal device and method suitable for low-oil floating wastewater. This application can simultaneously achieve fully automatic adsorption and collection of floating oil in low-oil wastewater, and has the advantages of high removal efficiency, simple operation and maintenance, full automation of the entire set of equipment, and applicability to upgrading and retrofitting existing equipment.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides a fully automatic adsorption oil removal device suitable for low-floating oil wastewater, comprising:

[0008] A flow tank, with an oil suction roller and a driving device installed above the flow tank;

[0009] An oil-absorbing roller, on which an oil-absorbing felt is wound, is mounted on a drive device and can move back and forth and up and down along the surface of the floating oily wastewater in the flow pool, and can also rotate.

[0010] An oil collection tank, with a squeezing roller fixedly installed above it;

[0011] The extrusion roller can contact the oil-absorbing roller and exert a mutual extrusion action to squeeze out the oil absorbed by the oil-absorbing felt and let it fall into the oil collection tank.

[0012] Furthermore, the driving device of this application includes a gear and a rack assembly disposed on the top of the walls on both sides of the flow pool; both ends of the rack assembly are fixed to the top of the walls on both sides of the flow pool by rack assembly fixers; both ends of the oil suction roller are connected to the gear through an oil suction drum fixed track; the gear is disposed on the rack assembly and meshes with the rack assembly; the gear is connected to the oil suction drum moving motor through the transmission shaft of the oil suction drum moving motor, and the oil suction drum moving motor drives the gear to rotate, thereby driving the oil suction roller to move back and forth along the surface of the floating oil wastewater in the flow pool.

[0013] Furthermore, a stepper motor is installed on the fixed track of the oil suction drum in this application, and the oil suction drum can move up and down along the fixed track under the drive of the stepper motor.

[0014] Furthermore, the oil suction drum of this application has a built-in rotating motor, which can drive the oil suction drum and the oil suction felt to rotate at the oil-water mixing interface.

[0015] Furthermore, in this application, the oil-absorbing drum and oil-absorbing felt rotate in opposite directions to the water flow at the oil-water mixing interface.

[0016] Furthermore, the two ends of the pressing roller in this application are respectively connected to the pressing drum rotating motor via the transmission shaft of the pressing drum rotating motor, and are fixedly installed on the top of the walls on both sides of the oil collection tank via the pressing drum fixing device.

[0017] Furthermore, the extrusion drum of this application has a built-in rotating motor, which can drive the extrusion drum to rotate.

[0018] Furthermore, when the oil-absorbing felt of this application moves to contact the extrusion cylinder, they squeeze and discharge the absorbed oil in opposite directions of rotation and collect it in the oil collection tank.

[0019] Secondly, this application provides a fully automated adsorption oil removal method suitable for low-floating-oil wastewater, comprising the following steps:

[0020] As the oil-absorbing drum rotates, the oil-absorbing felt wrapped around it rotates on its own axis. At the same time, the moving motor of the oil-absorbing drum drives the meshing of the gear and rack group to make the whole structure move forward, so that the oil-absorbing felt rotates on the surface of the oily wastewater and moves forward at the same time, fully absorbing the floating oil.

[0021] When the oil suction drum moves to the edge of the flow tank, the fixed track of the oil suction drum lifts the oil suction drum upward. Then the oil suction drum continues to move horizontally until it contacts the extrusion drum. The extrusion drum rotation motor is started, and the oil suction drum and the extrusion drum move towards each other to realize the extrusion and regeneration of the oil-absorbing felt.

[0022] After the oil-absorbing felt squeezes out the oil, it moves in the opposite direction to the farthest end of the squeezing drum, and then moves to one side of the squeezing drum. This cycle is repeated to achieve oil adsorption and discharge.

[0023] Compared with the prior art, this application has the following beneficial effects:

[0024] This application's oil-absorbing felt rotates with the rotation of the drive shaft, which in turn drives the gears forward. The overall structure allows the oil-absorbing felt to rotate and move forward simultaneously on the water surface. The oil-absorbing felt contacts the floating oil in the flow-through tank in a counter-current manner, achieving full adsorption. When the oil-absorbing felt reaches contact with the rotating drum, they squeeze and expel the adsorbed oil in opposite directions of rotation, collecting it in the oil collection tank, ensuring timely and continuous discharge of the oil. After expelling the oil, the oil-absorbing felt moves in the opposite direction to the farthest end of the flow-through tank from the rotating drum, and then moves back towards the end of the drum, thus completing the cycle. This achieves automated and continuous oil adsorption and discharge, as well as the recycling of the oil-absorbing felt. Attached Figure Description

[0034] The present application will now be described in further detail with reference to the accompanying drawings:

[0035] See Figure 1 This application discloses a fully automatic adsorption oil removal device suitable for low-floating oil wastewater, including a rack assembly 1, a rack assembly holder 2, a gear 3, a moving motor 4 for an oil suction drum 6, a drive shaft for the moving motor 4 of the oil suction drum 6, an oil suction drum 6, an oil suction felt 7, a fixed track for the oil suction drum 6, a squeezing drum 9, a squeezing drum 9 holder, a rotating motor for the squeezing drum 9, a drive shaft for the rotating motor of the squeezing drum 9, a flow tank 13, and an oil collection tank 14.

[0036] Rack assembly 1 is arranged on the top of the walls on both sides of the flow pool 13, and is fixed at both ends by rack assembly retainers 2. Gear 3 is placed on top of rack assembly 1 and meshes with rack assembly 1. The outer side of gear 3 is connected to the drive shaft 5 of the oil suction drum moving motor. One side of the drive shaft 5 of the oil suction drum moving motor is connected to the oil suction drum moving motor 4. The inner side of gear 3 is connected to the oil suction drum fixed track 8. The inner side of the oil suction drum fixed track 8 is connected to the oil suction drum 6. Oil absorption felt 7 is wrapped around the oil suction drum 6. Squeeze drum retainers 10 are arranged on the top of the walls on both sides of the oil collection pool 14. Both sides of the squeeze drum rotating motor drive shaft 12 are connected to the squeeze drum retainers 10. Both sides of the squeeze drum 9 are connected to the squeeze drum rotating motor drive shaft 12. One side of the squeeze drum rotating motor drive shaft 12 is connected to the squeeze drum rotating motor 11.

[0037] The oil suction drum 6 has a built-in rotating motor, which drives the oil suction drum 6 and the oil absorption felt 7 to rotate at the oil-water mixing interface. The direction of rotation of the oil suction drum 6 and the oil absorption felt 7 at the oil-water mixing interface is opposite to the direction of water flow. After the gear 3 meshes with the rack and pinion 1, it drives the oil suction drum 6 and the oil absorption felt 7 to reciprocate along the direction of the rack and pinion. A stepper motor is installed on the fixed track 8 of the oil suction drum, allowing the oil suction drum 6 to move up and down along the fixed track 8.

[0038] The extrusion drum 9 has a built-in rotating motor that drives it to rotate. When the oil-absorbing felt 7 comes into contact with the extrusion drum 9, they rotate in opposite directions to squeeze and discharge the absorbed oil, which is then collected in the oil collection tank 14. After the oil is discharged, the oil-absorbing felt 7 moves in the opposite direction to the farthest end of the extrusion drum 9, and then moves back to one side of the drum 9. This cycle repeats, achieving automated and continuous oil adsorption and discharge, and recycling of the oil-absorbing felt.

[0039] The working process for this application is as follows:

[0040] In actual operation, as the oil-absorbing drum 6 rotates, the oil-absorbing felt 7 wrapped around it also rotates. Simultaneously, the oil-absorbing drum moving motor 4 drives the gear 3 to mesh with the rack and pinion group 1, causing the entire structure to move forward. This allows the oil-absorbing felt 7 to rotate on the surface of the oily wastewater while moving forward, fully absorbing the floating oil. When the oil-absorbing drum 6 reaches the edge of the flow tank 13, the oil-absorbing drum fixed track 8 lifts the oil-absorbing drum 6 upward. Then, the oil-absorbing drum 6 continues to move horizontally until it contacts the extrusion drum 9. The extrusion drum rotation motor 11 then starts, and the oil-absorbing drum 6 and the extrusion drum 9 move towards each other, realizing the extrusion and regeneration of the oil-absorbing felt 7.

[0041] After the oil-absorbing felt 7 squeezes out the oil, it moves in the opposite direction to the farthest end of the squeezing drum 9, and then moves to one side of the squeezing drum 9. This cycle is repeated to achieve the automation and continuity of oil adsorption and discharge, and the recycling of the oil-absorbing felt.

[0042] This application enables the oil-absorbing felt to fully contact and rapidly absorb the floating oil in the flow tank. Its rotation and forward movement simultaneously automate the absorption process. The compression between the oil-absorbing felt and the rotating drum promptly discharges the absorbed oil, and the recirculation process ensures continuous oil absorption and discharge, as well as the recycling of the oil-absorbing felt. This achieves the goal of removing floating oil with water, reducing the risk of subsequent equipment being contaminated and clogged by oil.

[0043] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
