Description

Technical Field

[0001] This utility model relates to the field of degreasing tank technology, and in particular to an oil removal and purification device for a degreasing tank. Background Technology

[0002] A degreasing tank is a processing device used to remove oil, grease, and impurities from the surface of metals or workpieces. It is widely used in metal surface treatment, coating, printing, automobile manufacturing, and other fields. Degreasing tanks remove oil from the surface of workpieces using chemical or physical methods to ensure the quality and effectiveness of subsequent processes (such as spraying, electroplating, printing, etc.).

[0003] During continuous operation, degreasing tanks accumulate a large amount of floating oil on the surface of the liquid. This floating oil not only reduces the cleaning efficiency of the degreasing solution and affects the quality of subsequent processes, but may also cause the solution to deteriorate prematurely, increasing production costs and the burden of waste liquid treatment. Currently, common oil removal methods mainly rely on manual skimming or the installation of fixed oil skimmers, but these methods suffer from problems such as low efficiency, inability to operate continuously, incomplete oil-water separation, and poor purification effects. Furthermore, the separated water is not effectively recycled, resulting in resource waste.

[0004] Therefore, we propose an oil removal and purification device for a degreasing tank. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil removal and purification device for a degreasing tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oil removal and purification device for a degreasing tank, comprising a degreasing tank body and a controller fixedly embedded in the outer wall of one side of the degreasing tank body. Two support frames are symmetrically fixedly connected to the outer wall of one side of the degreasing tank body. An oil removal tank is fixedly connected to the top of the two support frames. A pump assembly is installed on one side of the oil removal tank. A float-type suction pipe is fixedly connected to the oil suction end of the pump assembly.

[0007] The oil removal tank has an internal frame, and the bottom of the frame and the inner walls on both sides are fixedly connected to an inclined water weir. The inner walls on both sides of the frame are fixedly connected to a float.

[0008] A reflux assembly is fixedly connected between the bottom of the frame and the degreasing tank body.

[0009] Furthermore, an inlet pipe and an outlet pipe are fixedly connected to one side of the outer wall of the degreasing tank body, and the inlet pipe is located above the outlet pipe, which is beneficial for replenishing water to the degreasing tank and for discharging wastewater.

[0010] Furthermore, the pump assembly includes a self-priming oil pump, and the oil outlet of the self-priming oil pump is fixedly connected to the oil removal tank. The mounting base of the self-priming oil pump is fixedly connected to the outer wall of the oil removal tank. The oil inlet of the self-priming oil pump is fixedly connected to a first flexible hose. This design directly fixes the pump body to the oil removal tank, resulting in a compact structure and reduced pipeline layout.

[0011] Furthermore, the float-type suction tube includes a thick tube, which is fixedly connected to the bottom of the first flexible tube. The outer surface of the thick tube is partially covered and fixedly connected to a float plate, which provides sufficient buoyancy for the thick tube to ensure that the suction port always floats near the liquid surface.

[0012] Furthermore, the top of the float plate is symmetrically provided with two sliding rods extending downwards, and the sliding rods are slidably connected to the float plate. The top of each of the two sliding rods is fixedly connected to a mounting seat, and the mounting seat is fixedly installed on the top of the degreasing tank body. The sliding rods and the mounting seats form a vertical guiding mechanism, which allows the float plate to float freely up and down with the liquid surface, while strictly limiting its horizontal movement.

[0013] Furthermore, an electric control valve is fixedly connected to one side of the bottom of the oil removal tank, which is easy to operate and avoids the inconvenience of manual oil drainage and the potential secondary pollution.

[0014] Furthermore, the reflux assembly includes a straight pipe, which is fixedly connected to the bottom of the frame. The straight pipe passes through the degreasing tank and is slidably connected to the degreasing tank. A second flexible hose is fixedly connected to the bottom of the straight pipe and is fixedly connected to the degreasing tank body. The slidable connection between the straight pipe and the degreasing tank allows the internal separation frame to float slightly adaptively under buoyancy, while the reflux pipeline remains unobstructed.

[0015] The beneficial effects of this utility model are:

[0016] In use, this invention continuously sucks up floating oil from the liquid surface through a float-type suction pipe. The float in the oil removal tank blocks the grease and, together with the inclined water weir, achieves effective oil-water separation. The separated clean water is automatically returned to the degreasing tank for recycling through the reflux assembly. This realizes continuous automated operation of oil collection, separation, and reflux, significantly improving oil removal efficiency, reducing energy consumption, minimizing manual intervention, and saving water resources.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-3 As shown, an oil removal and purification device for a degreasing tank is disclosed, comprising a degreasing tank body 1 and a controller 4 fixedly embedded in the outer wall of one side of the degreasing tank body 1. Two support frames 8 are symmetrically fixedly connected to the outer wall of one side of the degreasing tank body 1. An oil removal tank 6 is fixedly connected to the top of the two support frames 8. A pump assembly is installed on one side of the oil removal tank 6. The pump assembly includes a self-priming oil pump 7, and the oil outlet end of the self-priming oil pump 7 is fixedly connected to the oil removal tank 6. The mounting base of the self-priming oil pump 7 is fixedly fixed to the outer wall of the oil removal tank 6. A first hose 5 is fixedly connected to the oil inlet end of the self-priming oil pump 7. The first hose 5 is an oil-resistant and heat-resistant flexible hose (such as a fluororubber hose). The self-priming oil pump 7 is the power core of the pump assembly, and its mounting base is rigidly fixed to the outer wall of the oil removal tank 6 by bolts.

[0025] The pump assembly's suction end is fixedly connected to a float-type suction pipe, which includes a thick pipe 9. The thick pipe 9 is fixedly connected to the bottom of the first flexible hose 5. The outer surface of the thick pipe 9 partially covers and is fixedly connected to a float 10. Two sliding rods 11 are symmetrically arranged on the top of the float 10, extending downwards. The sliding rods 11 are slidably connected to the float 10. The top of each sliding rod 11 is fixedly connected to a mounting seat 13, which is fixedly installed on the top of the degreasing tank body 1. The sliding rods 11 are smooth metal round rods that vertically pass through a pre-set sliding sleeve or hole on the float 10, forming a sliding pair. Its function is to provide vertical guidance for the floating unit composed of the float 10 and the thick pipe 9, restricting it to float freely in the vertical direction with changes in liquid level, preventing it from drifting randomly on the liquid surface, and ensuring that the suction port position is relatively fixed.

[0026] An electrically controlled valve 12 is fixedly connected to one side of the bottom of the oil separator 6. The electrically controlled valve 12 is an electrically operated butterfly valve or ball valve. Inside the oil separator 6, there is a frame 16. The bottom and the inner walls of both sides of the frame 16 are fixedly connected to an inclined water weir 17. The inner walls of both sides of the frame 16 are fixedly connected to a float 18. The float 18 is a closed hollow cylinder, horizontally fixed in front of the inlet of the frame 16, with part of it submerged in the liquid and part of it exposed above the liquid surface. Its function is to act as a mechanical barrier to prevent the pumped oil-water mixture from directly impacting the water weir 17.

[0027] A return assembly is fixedly connected between the bottom of the frame 16 and the degreasing tank body 1. The return assembly includes a straight pipe 14, which is fixedly connected to the bottom of the frame 16. The straight pipe 14 passes through the oil removal tank 6 and is slidably connected to the oil removal tank 6. A second flexible hose 15 is fixedly connected to the bottom of the straight pipe 14 and is fixedly connected to the degreasing tank body 1. The straight pipe 14 is a vertically set rigid pipe that forms a dynamic sealed connection with the oil removal tank 6 through a sealing sleeve or stuffing box.

[0028] The outer wall of one side of the degreasing tank body 1 is fixedly connected to an inlet pipe 2 and an outlet pipe 3, with the inlet pipe 2 located above the outlet pipe 3. The inlet pipe 2 is located at the top and is used to replenish fresh degreasing liquid or water; the outlet pipe 3 is located at the bottom and is used to discharge the tank liquid or sediment that needs to be replaced.

[0029] The controller 4 is electrically connected to the degreasing tank body 1, the self-priming oil pump 7, and the electric control valve 12, which facilitates the control of the overall operation.

[0030] Working principle: After the equipment is started, the self-priming oil pump 7 begins to work. The self-priming oil pump 7 draws liquid from the surface of the degreasing tank body 1 through a float-type suction pipe (composed of a first flexible hose 5, a thick pipe 9, and a float 10). Due to the buoyancy provided by the float 10, the suction port of the thick pipe 9 always floats near the liquid surface, thus continuously drawing the surface oil and liquid mixture with the highest oil content.

[0031] The extracted oil-water mixture is directly pumped into the internal cavity of the oil removal tank 6 via the pump body. After the mixture enters the oil removal tank 6, the grease begins to float to the surface naturally due to the reduced flow rate and increased space.

[0032] The key component, float 18, is fixedly mounted on frame 16, acting as an oil skimmer or oil barrier. It blocks the floating oil accumulating on the upper layer, preventing it from easily approaching or crossing the water weir 17, thus confining the oil within the main chamber of the oil removal tank 6 to continue accumulating. The separated water can then freely flow into the interior of frame 16 through the edge of the water weir 17.

[0033] The water flowing into the frame 16 is a liquid that has undergone preliminary separation and has a very low oil content. This water flows smoothly back into the degreasing tank body 1 under the action of gravity through the return assembly (composed of a straight pipe 14 and a second flexible hose 15) at the bottom of the frame 16, thus realizing the recycling of water resources.

[0034] As the equipment continues to operate, the grease collected and blocked outside the float 18 accumulates more and more in the oil removal tank 6.

[0035] When it is necessary to discharge the collected waste oil, the electric control valve 12 at the bottom of the oil removal tank 6 can be opened to discharge the concentrated grease.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
