Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and particularly relates to an oily wastewater treatment device. Background Art

[0002] After machining, a large amount of chips, lubricating oil, rust preventive oil and other stains usually adhere to the surface of parts. Therefore, before the surface treatment of parts, degreasing treatment needs to be carried out on the surface of parts. The common method is to immerse the parts in a degreasing tank for cleaning. However, a large amount of wastewater will be generated during the cleaning process, and these wastewaters contain pollutants such as oil stains, surfactants and emulsification products. If directly discharged into the environment, it will pollute the environment;

[0003] The traditional method for removing oil stains from oily wastewater is to directly filter the wastewater with an adsorption plate. However, during the filtering process, the oil stains will stick to the surface of the adsorption plate, blocking the filter holes on the adsorption plate, resulting in the inability to continuously filter. To solve the above problems, an oily wastewater treatment device is provided.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0005] To solve the above problems, the purpose of the utility model is to provide an oily wastewater treatment device. By setting an oil-absorbing cotton and a fixing member capable of fixing the oil-absorbing cotton, the oil-absorbing cotton can float on the liquid surface in the treatment tank to adsorb the oil stains on the surface of the sewage. When the oil-absorbing cotton is full of oil stains, it can be removed and the adsorbed oil stains can be squeezed out. This oily wastewater treatment method can avoid the problem that the subsequent filtration cannot be continuously carried out due to the blockage of the adsorption plate by oil stains compared with the method of directly filtering the wastewater with an adsorption plate.

[0006] To achieve the above purpose, the utility model provides an oily wastewater treatment device. The wastewater treatment device includes a treatment tank, and an oil-absorbing cotton for absorbing oil stains is arranged in the treatment tank. Fixing components for fixing the oil-absorbing cotton are slidably arranged inside both ends of the treatment tank.

[0007] Vertical T-shaped sliding rails are opened on the inner walls at both ends of the treatment tank, and the upper ends of the T-shaped sliding rails are communicated with the outside.

[0008] The fixing component includes a T-shaped slider adapted to the T-shaped sliding rail. A connecting shaft is slidably arranged on the T-shaped slider. A driving box is fixed on the connecting shaft. A motor is fixed inside the driving box. The output shaft of the motor penetrates through the side plate of the driving box away from the T-shaped slider and is fixed with a connecting block. First cylinders are fixed on both sides of the connecting block, and clamps are fixed on the output shafts of the first cylinders.

[0009] Furthermore, a spring is fixedly connected between the driving box and the T-shaped slider.

[0010] Further, the fixture includes an L-shaped bracket fixed on the output shaft of the first cylinder. A first clamping plate is fixed on the vertical plate of the L-shaped bracket. A second cylinder is fixed on the top plate of the first clamping plate. The output shaft of the second cylinder penetrates through the top plate of the first clamping plate and is fixed with a second clamping plate corresponding to the first clamping plate.

[0011] Further, symmetrically distributed lifting components are fixed on one side of the treatment tank.

[0012] Further, a slot is fixed below the drive box.

[0013] Further, the lifting components include a first connecting bar vertically fixed on one side of the treatment tank. A third cylinder is fixed below the first connecting bar. The output shaft of the third cylinder penetrates through the first connecting bar and is vertically fixed with a fourth cylinder. The output shaft of the fourth cylinder faces the treatment tank. An L-shaped connecting bar is fixed on the output shaft of the fourth cylinder. A plug block adapted to the slot is fixed above the horizontal plate of the L-shaped connecting bar.

[0014] Further, the wastewater treatment device further includes a collection tank for collecting oil stains, and the collection tank is placed on one side of the treatment tank.

[0015] The oil-contaminated wastewater treatment device proposed by the present utility model can bring the following beneficial effects:

[0016] 1. By arranging the oil-absorbing cotton and the fixing parts capable of fixing the oil-absorbing cotton, the oil-absorbing cotton can float on the liquid surface in the treatment tank to adsorb the oil stains on the surface of the sewage. When the oil-absorbing cotton is full of oil stains, it can be removed and the adsorbed oil stains can be squeezed out. Compared with the method of directly filtering the wastewater with an adsorption plate, this oil-contaminated wastewater treatment method can avoid the problem that the adsorption plate is blocked by oil stains, resulting in the subsequent filtration being unable to continue.

[0017] 2. By arranging the lifting components, the present utility model's wastewater treatment device can control the automatic entry and exit of the fixing components into and out of the treatment tank, enabling the automatic treatment of wastewater by the wastewater treatment device, reducing the use of labor, and the wastewater treatment device has a simple structure and is suitable for practical use.

[0028] An embodiment of the present utility model provides an oily wastewater treatment device. The wastewater treatment device includes a treatment tank 1, as Figure 1 shown. An oil-absorbing cotton 3 for absorbing oil is provided in the treatment tank 1. Fixed components 2 for fixing the oil-absorbing cotton 3 are slidably provided inside both ends of the treatment tank 1. A symmetrically distributed lifting component 5 is fixed on one side of the treatment tank 1. The wastewater treatment device further includes a collection tank 4 for collecting oil, and the collection tank 4 is placed on one side of the treatment tank 1.

[0029] Vertical T-shaped sliding rails 11 are provided on the inner walls at both ends of the treatment tank 1, and the upper ends of the T-shaped sliding rails 11 communicate with the outside.

[0030] The fixed component 2 includes a T-shaped slider 22 adapted to the T-shaped sliding rail 11. As Figure 2 shown, a connecting shaft 211 is slidably provided on the T-shaped slider 22. A driving box 21 is fixed on the connecting shaft 211. A spring 212 is fixedly connected between the driving box 21 and the T-shaped slider 22. A motor 29 is fixed inside the driving box 21. The output shaft of the motor 29 penetrates through the side plate of the driving box 21 away from the T-shaped slider 22 and is fixed with a connecting block 23. A slot 210 is fixed below the driving box 21. First cylinders 24 are fixed on both sides of the connecting block 23, and clamps are fixed on the output shafts of the first cylinders 24.

[0031] The clamp includes an L-shaped bracket 25 fixed on the output shaft of the first cylinder 24. A first clamping plate 26 is fixed on the vertical plate of the L-shaped bracket 25.

The third cylinder 52 and the fourth cylinder 53 cooperate to control the two T-shaped sliders 22 to slide into the T-shaped slide rails 11 respectively. The third cylinder 52 is contracted to control the oil-absorbing cotton 3 to descend. When the oil-absorbing cotton 3 contacts the liquid surface, the oil-absorbing cotton 3 floats on the water surface to absorb oil stains, and the insertion block 55 is separated from the insertion slot 210.

[0035] When the oil-absorbing cotton 3 is full of oil stains, the third cylinder 52 is extended to control the oil-absorbing cotton 3 to move out of the treatment tank 1. The fourth cylinder 53 is started to control the oil-absorbing cotton 3 to move above the collection box 4. By controlling the two motors 29 to rotate in the reverse direction, the oil stains in the oil-absorbing cotton 3 are squeezed out into the collection box 4 for collection, so as to avoid polluting the environment with the oil stains in the oil-contaminated wastewater.
