Description

Technical Field

[0001] This utility model belongs to the field of oily wastewater treatment technology, specifically relating to a mechanically processed oily wastewater hydrocyclone separator. Background Technology

[0002] In the machining industry (such as automotive parts manufacturing, machine tool processing, and hardware forging), processes like cutting, grinding, and stamping require large amounts of oil-containing coolants (such as emulsions and cutting oils). After use, these coolants mix with metal shavings, dust, emulsion impurities, and other pollutants, forming oily wastewater from machining. Direct discharge of this wastewater not only causes serious water pollution (oil forms an oil film on the water surface, hindering dissolved oxygen exchange and causing aquatic life to die), but also wastes recyclable oil resources. Therefore, efficient separation and treatment of oily wastewater has become a core requirement for machining enterprises to achieve environmental compliance and resource recycling.

[0003] In current methods, oily wastewater is treated by using hydrocyclones to separate the oil and water before direct discharge. However, since there are many iron filings or impurities in the machining wastewater, it is not convenient to filter and recover the metallic or non-metallic impurities in the wastewater after oil-water separation, which easily leads to resource waste. Utility Model Content

[0004] The purpose of this invention is to provide a hydrocyclone separator for oily wastewater from mechanical processing, which can filter and recycle metallic and non-metallic impurities in the wastewater. On the one hand, it can ensure the cleanliness of the discharged water, and on the other hand, it can improve the recycling rate of metallic or non-metallic impurities.

[0005] The specific technical solution adopted by this utility model is as follows: A hydrocyclone separator for oily wastewater from mechanical processing includes a hydrocyclone, an oil-water input pipe fixedly connected to the side wall of the hydrocyclone near the top surface, an oil outlet pipe fixedly connected to the top surface of the hydrocyclone, a water outlet pipe fixedly connected to the bottom of the hydrocyclone, and a guide pipe bolted to the bottom end of the water outlet pipe. The guide pipe has a V-shaped structure and a filter assembly is provided inside the guide pipe.

[0006] Furthermore, the filter assembly includes a filter cylinder threadedly connected inside the guide pipe, the filter cylinder having an opening at one end near the outlet pipe, the filter cylinder having several through holes on its side wall, and the guide pipe having several through grooves near both ends on its side wall.

[0007] Furthermore, a magnetic rod is detachably connected to the bottom surface of the inner cavity of the filter cartridge.

[0008] Furthermore, the magnetic rod and the filter cylinder are connected by a thread.

[0009] Furthermore, each filter cartridge has two handles fixedly connected to its bottom end.

[0010] Furthermore, two annular plates are fixedly connected to the inner wall of the guide tube. The annular plates have a triangular cross-section. A sealing ring is fitted on the side wall of the annular plate near the filter cylinder, and the sealing ring abuts against the end face of the filter cylinder.

[0011] Furthermore, annular flow dividers are fixedly connected to the inner wall of the guide tube at the corners.

[0012] The technical effects achieved by this utility model are as follows: This utility model discloses a hydrocyclone separator for oily wastewater from mechanical processing. Through the cooperation of hydrocyclones, guide pipes, and filter components, it can filter and recycle metallic and non-metallic impurities in wastewater.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-5As shown, a hydrocyclone separator for oily wastewater from mechanical processing includes a hydrocyclone 1. An oil-water inlet pipe 2 is fixedly connected to the side wall of the hydrocyclone 1 near the top surface. An oil outlet pipe 3 is fixedly connected to the top surface of the hydrocyclone 1. A water outlet pipe 4 is fixedly connected to the bottom of the hydrocyclone 1. A guide pipe 5 is bolted to the bottom end of the water outlet pipe 4. The guide pipe 5 has a V-shaped structure and a filter assembly is installed inside the guide pipe 5.

[0017] like Figure 3 and Figure 4 As shown, the filter assembly includes a filter cylinder 6 threadedly connected to the guide pipe 5. The filter cylinder 6 is open at one end near the outlet pipe 4. Several through holes 7 are provided on the side wall of the filter cylinder 6. Several through grooves 8 are provided on the side wall of the guide pipe 5 near both ends.

[0018] In this filter cartridge 6, the through hole 7 and the through groove 8 are in a connected state. When the water flows out, it can be discharged through the through groove 8. At this time, the through hole 7 blocks impurities in the filter cartridge 6, which facilitates the filtration and collection of metal impurities (iron filings, aluminum filings, etc.) or non-metallic impurities (plastics, other impurities), so that the discharged water is kept clean.

[0019] like Figure 3 As shown, a magnetic rod 9 is detachably connected to the bottom surface of the inner cavity of the filter cartridge 6. The magnetic rod 9 is connected to the filter cartridge 6 by a thread. If the impurities contain magnetic impurities, they can be adsorbed and collected by the magnetic rod 9, achieving efficient separation of magnetic and non-magnetic impurities in the filter cartridge 6. When too many impurities are adsorbed on the magnetic rod 9, the magnetic rod 9 can be rotated to remove it from the filter cartridge 6 for cleaning, thereby increasing the flexibility of use.

[0020] like Figure 2 As shown, two handles 10 are fixedly connected to the bottom of each filter cartridge 6. The handles 10 serve as the force-bearing components of the filter cartridge 6. When removing the filter cartridge 6, holding the handles 10 makes it easy to rotate the filter cartridge 6 and detach it from the guide tube 5, thus achieving convenient disassembly and installation.

[0021] like Figure 5 As shown, two annular plates 11 are fixedly connected to the inner wall of the guide tube 5. The annular plates 11 have a triangular cross-section. A sealing ring 12 is fitted on the side wall of the annular plate 11 near the filter cylinder 6. The sealing ring 12 abuts against the end face of the filter cylinder 6. When the filter cylinder 6 is screwed into the guide tube 5, after the end face of the filter cylinder 6 abuts against the sealing ring 12, a slight rotation can further improve the sealing performance between the filter cylinder 6 and the sealing ring 12.

[0022] like Figure 3 As shown, annular flow dividers 13 are fixedly connected to the inner wall of the guide pipe 5 at the corners. The annular flow dividers 13 can be used as optional components. In actual use, it is optional to use them. When used, they can quickly guide the water flow, causing the water flow to disperse to both sides from the corners of the guide pipe 5.

[0023] The working principle of this utility model is as follows: First, the guide pipe 5 is connected to the outlet pipe 4 of the hydrocyclone 1 by bolts. After the oil and water are separated, the water flows from the outlet pipe 4 into the guide pipe 5 and is divided by the annular diverter plate 13 into the guide pipe 5 respectively. The water flows to both ends of the guide pipe 5 and is discharged from the through hole 7 and through groove 8. At this time, the metal impurities and non-metal impurities in the water are collected in the filter cylinder 6. At the same time, the magnetic metal impurities are attracted to the magnetic rod 9. When there are a lot of impurities in the filter cylinder 6, the filter cylinder 6 can be rotated and unscrewed by the handle 10 for cleaning and reuse.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
