Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater treatment, in particular to an improved electroplating wastewater oil removal device. Background Art

[0002] The workpiece is exposed to a lot of oil stains during production. In the electroplating working environment, the workpiece needs to be cleaned first. The wastewater after cleaning contains a lot of oil stains, sludge, chemical components and other components that pollute the environment. When treating this kind of wastewater, it is necessary to remove the oil from the wastewater first and then treat it in the next step.

[0003] Patent announcement number "CN217077062U" discloses "an electroplating wastewater oil removal device", which includes a mixed separation box, a fixed splint is fixed on one side wall of the separation box, a conveying cylinder is fixed on the inner wall of the fixed splint, a liquid inlet pipe is connected between the top of the conveying cylinder and the top surface of the separation box, the inner wall of the conveying cylinder is rotatably connected to the rotating shaft a, and the interior of the conveying cylinder is provided with a spiral blade that is tightly sleeved with the rotating shaft a. Driven by the driving motor, the cleaning liquid is spirally conveyed to the top of the conveying cylinder through the spiral blade and falls onto the oil-absorbing cotton sleeve in the separation box. The extrusion rod drives the extrusion plate to reciprocate on the guide plate a, thereby realizing reciprocating extrusion of the oil-absorbing cotton sleeve, so that the oil can better fall into the liquid accumulation area on the screening plate, thereby improving the oil absorption effect of the oil and water conveyed by the conveying cylinder.

[0004] In the above technology, when deoiling wastewater, the wastewater is transported by spiral conveyance through oil-absorbing cotton to absorb the grease in the wastewater. During the wastewater transportation process, the grease in the wastewater will not merge with the water, but will be broken into smaller oil particles. When the wastewater falls on the oil-absorbing cotton, water splashes, and the water splashes carry oil particles. After these oil particles cannot splash out, they cannot be absorbed by the oil-absorbing cotton again, resulting in the inability to completely absorb the waste oil during waste oil treatment.

[0029] The present application is further described in detail below through drawings and examples.

[0030] Reference Figures 1 to 4The embodiment of the present application provides an improved electroplating wastewater oil removal device, including a main body box 1, a partition 5 is fixedly installed inside the main body box 1, a cleaning component 2 is arranged on the outside of the main body box 1, an extrusion component 3 is arranged on the top of the main body box 1 and on the left side of the partition 5, and a rotating component 4 is arranged on the back of the main body box 1.

[0031] The oil-absorbing cotton 210 is located at the opening at the top of the main box 1, the oil-absorbing cotton 210 is located on the right side of the partition 5, the bottom of the oil-absorbing cotton 210 is located inside the main box 1, and the top of the oil-absorbing cotton 210 is located above and outside the main box 1. A first motor 25 is fixedly installed on the right side of the front support frame 22, and the output end of the first motor 25 movably passes through the interior of the support frame 22 and is fixedly connected to the first screw 23.

[0032] The rotating assembly 4 includes a base plate 43, which is fixedly mounted on the back of the main box 1. A rack 42 is fixedly mounted on the top of the base plate 43. A gear 41 is fixedly mounted on the outer side of the back rotating rod 28. The gear 41 is meshed with the top of the rack 42. The rack 42 is arranged on the right side of the back partition 5 of the main box 1.

[0033] In this embodiment, the main body box 1 is divided into two parts, the right side is used to hold uncleaned wastewater, and the left side is used to hold cleaned oil. First, the wastewater is introduced into the right side of the partition 5 inside the main body box 1 through an external pipe, and the injection height is slightly higher than the bottom height of the oil-absorbing cotton 210, and then it is allowed to stand. Since the density of oil is less than that of water and it is insoluble in water, the oil will separate from the water and float above the water surface after a period of time. The oil-absorbing cotton 210 is made of oleophilic ultrafine fiber non-woven fabric, does not contain chemical agents, will not cause secondary pollution, and can quickly absorb oil, organic solvents, hydrocarbons, vegetable oils and other liquids that are dozens of times its own weight. After dehydration and deoiling, the oil-absorbing cotton 210 can only absorb oil without absorbing water. After standing still, the first motor 25 is started to drive The first screw 23 is driven to rotate, and the rotation of the first screw 23 drives the slider 24 thereon to move left and right, and drives the upper electric push rod 26 and the side block 27 to move, so that the oil-absorbing cotton 210 can be driven to move left and right along the main box 1, and the gear 41 will roll along the rack 42 during the movement, so that the gear 41 drives the rotating rod 28 and the oil-absorbing cotton 210 to roll, so that the oil-absorbing cotton 210 can move along the water surface and roll at the same time, and the oil-absorbing cotton 210 can roll along the water surface to absorb the oil on the surface, and the rolling oil-absorbing cotton 210 can make the outside of the oil-absorbing cotton 210 absorb the oil, this method can ensure that the oil is absorbed more thoroughly; and after the oil is absorbed, the valve on the right side of the main box 1 can be opened to discharge the treated water.

[0034] Reference Figures 1 to 4 In one aspect of the present embodiment, the extrusion assembly 3 includes a limit plate 33 and a second motor 34, both of which are fixedly mounted on the top of the bracket plate 21, a second screw 35 is fixedly mounted on the output end of the second motor 34, a top block 36 is fixedly mounted on the side of the limit plate 33, and the top of the second screw 35 is rotatably connected to the bottom of the top block 36.

[0035] The threads on both sides of the center of the second screw 35 have different rotation directions. The outer sides of the two threads of the second screw 35 with different rotation directions are both screwed with a moving plate 32. The moving plate 32 is slidably connected to the side of the limiting plate 33. The two moving plates 32 are fixedly installed on the opposite sides with an extrusion plate 31. A connecting groove 37 is opened inside the extrusion plate 31, and the extrusion plate 31 is an arc plate.

[0036] After the oil-absorbing cotton 210 absorbs the oil, the slider 24 and the oil-absorbing cotton 210 continue to move. After moving to the right side of the partition 5, the electric push rod 26 is started to drive the oil-absorbing cotton 210 to rise. After rising, the oil-absorbing cotton 210 continues to move, and the oil-absorbing cotton 210 will move to the left side of the partition 5. When the oil-absorbing cotton 210 moves to the left, it will move between the upper and lower extrusion plates 31, and adjust its position by the electric push rod 26 to place the oil-absorbing cotton 210 in the middle of the two extrusion plates 31. Then, the second motor 34 is started to drive the second screw 35 to rotate. The second motors 34 on both sides are started synchronously and rotate at the same speed. The rotation of the second screw 35 drives the moving plates 32 on both sides to move synchronously in the opposite direction with the extrusion plates 31, and the extrusion plates 31 are synchronously moved to the oil-absorbing cotton 210 through the extrusion plates 31 and squeezed. After squeezing, the oil absorbed inside will be squeezed out and fall into the left side of the partition 5, thereby achieving the effect of automatically cleaning the absorbed oil. The design of the connecting groove 37 enables the oil at the extrusion point to be better discharged outward.

[0037] Working principle: first, waste water is introduced into the right side of the partition 5 inside the main box 1 through an external pipe, and the injection height is slightly higher than the height of the bottom of the oil-absorbing cotton 210, and then it is allowed to stand. Since the density of oil is lower than that of water and it is insoluble in water, after a period of time, the oil will be separated from the water and float above the water surface. By starting the first motor 25 to drive the first screw 23 to rotate, the rotation of the first screw 23 drives the slider 24 thereon to move left and right, and drives the upper electric push rod 26 and the side block 27 to move, so that the oil-absorbing cotton 210 can be driven to move left and right along the main box 1, and during the movement, the gear 41 will roll along the rack 42, so that the gear 41 drives the rotating rod 28 and the oil-absorbing cotton 210 to roll, so that the oil-absorbing cotton 210 can roll while moving along the water surface, and the oil-absorbing cotton 210 can roll along the water surface to absorb the surface oil, and the rolling oil-absorbing cotton 210 can make the outside of the oil-absorbing cotton 210 absorb oil. This method can ensure that the oil is absorbed more thoroughly. After absorbing the oil, the slider 24 and the oil-absorbing cotton 210 continue to move. After moving to the right side of the partition 5, the electric push rod 26 is started to drive the oil-absorbing cotton 210 to rise. After rising, the oil-absorbing cotton 210 continues to move, and the oil-absorbing cotton 210 will move to the left side of the partition 5. When the oil-absorbing cotton 210 moves to the left side, it will move between the upper and lower extrusion plates 31, and adjust its position through the electric push rod 26 to place the oil-absorbing cotton 210 in the middle of the two extrusion plates 31. Then, the second motor 34 is started to drive the second screw 35 to rotate. The second motors 34 on both sides are started synchronously and rotate at the same speed. The rotation of the second screw 35 drives the moving plates 32 on both sides to move synchronously in the opposite direction with the extrusion plates 31, and the extrusion plates 31 are synchronously moved to the oil-absorbing cotton 210 and squeezed. After squeezing, the oil absorbed inside will be squeezed out and fall into the left side of the partition 5, thereby achieving the effect of automatically cleaning the absorbed oil. The design of the connecting groove 37 enables the oil at the extrusion point to be better discharged outward.
