Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing wastewater treatment, in particular to a mechanical processing wastewater oil-water separation device. Background Art

[0002] Wastewater is generated during the mechanical processing, and the wastewater is oily. If it is discharged directly into the river, the oil will float on the surface of the water, preventing oxygen in the air from dissolving in the water, leading to a lack of dissolved oxygen in the water, the death of aquatic organisms, and hindering the photosynthesis of aquatic plants. It may even cause the water to become smelly and the ecological balance of the water will be destroyed. Therefore, the wastewater from mechanical processing needs to be separated from the oil and water before being discharged.

[0003] When the existing wastewater oil-water separation device for mechanical processing is used, it is affected by the flow of wastewater. After the wastewater enters the device, it takes a long time to completely settle, causing the oil to float on the water surface and achieve the oil-water stratification effect. The oil-water separation efficiency is low and the use effect is poor. Utility Model Content

[0004] The present invention relates to a mechanical processing wastewater oil-water separation device, which solves the problem that the existing mechanical processing wastewater oil-water separation device is affected by the flow of wastewater during use, and the wastewater needs a long time to completely settle after entering the device, so that the oil floats on the water surface to achieve the oil-water stratification effect, resulting in low oil-water separation efficiency and poor use effect.

[0005] In a first aspect of the present disclosure, a device for separating oil-water from machining wastewater is provided, which specifically comprises: an oil-water separation box; a grooved baffle is installed inside the oil-water separation box, and a corrugated baffle is also installed inside the oil-water separation box; a filter residue basket is placed inside the oil-water separation box, and a top cover is rotatably connected to the top of the oil-water separation box; a pull rod is connected to the outside of the oil-water separation box.

[0006] Furthermore, the oil-water separation box is internally divided into a filter tank and a separation tank, and a through hole is provided inside the oil-water separation box, and the filter tank is connected with the separation tank through the through hole.

[0007] Furthermore, the filter residue basket is located in the filter tank provided in the oil-water separation box, handles are provided at both ends of the top of the filter residue basket, and a liquid inlet is provided inside the top cover, and the liquid inlet is located at the center of the top of the filter residue basket.

[0008] Furthermore, a drain port and an oil drain port are provided on the outside of the oil-water separation box. The drain port and the oil drain port are flush in height. The oil drain port is connected to the separation tank. The grooved baffle is installed on the inner side of the separation tank. The bottom of the grooved baffle is 2 cm away from the bottom end of the separation tank. The drain port is connected to the separation tank through the grooved baffle. When the wastewater enters the oil-water separation box through the liquid inlet, the metal debris carried in the wastewater is intercepted and filtered by the filter residue basket, so that the filtered wastewater enters the separation tank through the through hole. Utilizing the characteristic that water has a greater specific gravity than oil, the oil floats on the water surface. The water in the lower layer reaches the drain port through the grooved baffle and is discharged, and the oil in the upper layer is discharged from the oil drain port.

[0009] Furthermore, the corrugated baffles are arranged in a separation tank provided in the oil-water separation box, and the distance between the corrugated baffles is greater than 3 cm. When the filtered wastewater enters the separation tank through the through hole, the wastewater is blocked by the corrugated baffles, so that the wastewater in the separation tank can quickly stand still, so that the water and oil in the wastewater can be quickly separated.

[0010] Furthermore, two supporting legs are provided at one end of the bottom of the oil-water separation box, and two supporting wheels are rotatably connected to the other end of the bottom of the oil-water separation box, and the bottom of the supporting wheel is flush with the bottom of the supporting leg.

[0011] Furthermore, the oil-water separation box is provided with channel steels on opposite sides, and a pull rod is slidably connected in the channel steel. A sliding hole is provided on the outside of the channel steel, and sliding blocks are provided at opposite ends of the pull rod. The sliding blocks are slidably connected in the sliding holes. When the device needs to be moved, the pull rod can be pulled outward to support the bottom of the oil-water separation box through the support wheels, making the movement and transportation of the device easier and more labor-saving.

[0012] The utility model provides a mechanical processing wastewater oil-water separation device, which has the following beneficial effects:

[0013] When the utility model is in use, when waste water enters the oil-water separation box through the liquid inlet, the metal debris carried in the waste water is intercepted and filtered by the filter residue basket, so that the filtered waste water enters the separation tank through the through hole. Utilizing the characteristic that water has a greater specific gravity than oil, the oil floats on the water surface, and the water in the lower layer reaches the drain port through the grooved baffle plate for discharge, and the oil in the upper layer is discharged from the oil drain port, thereby achieving the oil-water separation effect; when the filtered waste water enters the separation tank through the through hole, the waste water is blocked by the corrugated baffle plate, so that the waste water in the separation tank can quickly stand still, thereby allowing the water and oil in the waste water to be quickly separated, thereby improving the oil-water separation efficiency.

[0014] In addition, when the device needs to be moved, the pull rod can be pulled outward to support the bottom of the oil-water separation box through the support wheels, making the movement and transportation of the device easier and more labor-saving. When the device is in use, the pull rod is retracted and the bottom of the oil-water separation box is supported by the support legs to ensure the stability of the device when in use.

[0015] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
