Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-water separation technology, and in particular to an oil-water separation device for rivet nut processing. Background Technology
[0002] During the rivet nut processing, a large amount of cooling lubricant, cutting fluid and cleaning agent are used for auxiliary processing. A large amount of oily wastewater is generated during the processing, which contains various metal shavings, oil stains and other impurities. In order to recover the lubricant and cutting fluid for reuse and to meet the requirements of sewage discharge, the oily wastewater needs to be discharged to oil-water separation equipment for treatment.
[0003] Traditional oil-water separation equipment typically receives oily wastewater, filters it simply with a filter screen, and then introduces the wastewater into the separation equipment. Methods such as gravity separation, centrifugal separation, or coalescence separation are used to separate the oil and water for further processing. However, this simple filtration process filters out all large particulate impurities in the oily wastewater. Recyclable metals and useless impurities are mixed together, making subsequent processing difficult and leading to resource waste. Furthermore, during prolonged operation, filter screen clogging can result in poor filtration efficiency, allowing large solid debris to enter subsequent separation equipment, causing wear and damage, increasing operating costs, and affecting subsequent processing efficiency.

Detailed Implementation
[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-3This utility model provides an embodiment of an oil-water separation device for rivet nut processing, comprising a protective shell 1, a motor 2 fixedly connected to the top of the inner wall of the protective shell 1, a worm gear 3 fixedly connected to the output end of the motor 2, a drive rod 5 rotatably connected to the inner wall of the protective shell 1, a worm wheel 4 fixedly connected to the outer wall of the drive rod 5, one end of a plurality of fixed rods 6 fixedly connected to the outer wall of the drive rod 5, a drum screen 8 fixedly connected to the other end of the plurality of fixed rods 6, a plurality of magnet frames 7 fixedly connected to the outer wall of the drum screen 8, a plurality of multifunctional rollers 9 rotatably connected to the inner wall of the protective shell 1, a screen plate 10 and a plurality of recycling tanks 21 slidably connected to the inner wall of the protective shell 1, an oil volume adjustment component provided on the inner wall of the protective shell 1, the worm gear 3 and the worm wheel 4 meshingly connected, the screen plate 10 slidably connected directly below the drum screen 8, and two layers of screen mesh provided from top to bottom on the inner wall of the screen plate 10, the upper layer of screen mesh having a larger aperture than the lower layer of screen mesh.
[0024] Specifically, the protective shell 1 protects and secures the internal components. A single motor 2 drives the subsequent components. The output of motor 2 drives the worm gear 3 to rotate, which in turn drives the worm wheel 4 and drive rod 5 to rotate. When drive rod 5 rotates, it drives the fixed rod 6 fixed to its outer wall, which in turn drives the magnet frame 7 and the drum screen 8 to rotate. Multiple magnets are embedded inside the multiple magnet frames 7. After being installed on the outer wall of the drum screen 8, the drum screen 8 becomes magnetic. When the mixed liquid enters, it flows out from the screen holes of the drum screen 8. The magnetic debris is attracted to the inner wall of the drum screen 8. Then the mixed liquid flows vertically down into the lower screen plate 10 for secondary filtration. The two layers of screens on the inner wall of the screen plate 10 enhance the filtration effect. Large particles are retained on the upper screen and small particles are retained on the lower screen, which facilitates the separate processing of different particles by removing the screen plate 10 later.
[0025] Reference Figure 3 and Figure 4 The oil volume regulating component includes a stratifier 15, which is fixedly connected to the right side of the inner wall of the protective shell 1. The inner wall of the protective shell 1 is provided with multiple water pipes 13, one of which is fixedly connected to and passes through the top of the stratifier 15. A valve core 20 is slidably connected to the inner wall of the water pipe 13. A connecting block 18 is fixedly connected to the right end of the outer wall of the valve core 20. A connecting rod 19 is fixedly connected to the inner wall of the stratifier 15. One end of a connecting rod 17 is fixedly connected to the bottom end of the connecting block 18. A float ball 16 is fixedly connected to the other end of the connecting rod 17.
[0026] Specifically, the mixture enters the separator 15 from the top through the water pipe 13 and undergoes static gravity separation. As the mixture gradually enters the separator 15, the float 16 floats above the oil layer due to buoyancy and gradually rises in height in the vertical direction, causing one end of the connecting rod 17 to rise synchronously. Since the other end of the connecting rod 17 is fixedly connected to the connecting block 18, the connecting block 18 rotates around the connecting rod 17. The connecting rod 17 simultaneously limits the connecting block 18 and the entire buoyancy device. When the bottom end of the connecting block 18 rises with the connecting rod 17, its top end causes the valve core 20 to slide deeper into the water pipe 13, gradually blocking the water outlet and slowing down the oil intake speed. When the water level is too high, the oil intake will stop, facilitating the separate processing of the separated oil and water. When the water level drops after processing, the float 16 descends with the water level, causing the subsequent components to move in the opposite direction and release oil.
[0027] Reference Figure 1 The inner wall of the protective shell 1 is rotatably connected to a rotating rod 12. The outer walls of the worm gear 3 and the rotating rod 12 are both fitted with pulleys 11. The outer walls of the two pulleys 11 are fitted with belts. The inner wall of the protective shell 1 is equipped with a centrifuge 14. The rotating rod 12 is fixedly connected to the input end of the centrifuge 14.
[0028] Specifically, the input end of the centrifuge 14 is connected via a rotating rod 12. A belt fitted over the outer wall of the rotating rod 12 and the worm gear 3 transmits the rotational power of the worm gear 3 to the centrifuge 14, driving its operation. This allows a single motor 2 to simultaneously drive the drum screen 8 and the centrifuge 14, saving equipment costs. In actual production, acceleration or reduction gear sets can be used to adjust the rotational speed of the drum screen 8 and the centrifuge 14 to meet filtration and separation requirements. The centrifuge 14 is used for the initial separation of the oil-water mixture.
[0029] Reference Figures 1-3 The outer wall of the multi-functional roller 9 is evenly provided with multiple scraper sections and load-bearing sections. The scraper sections are slidably connected to the outer wall of the drum screen 8, the load-bearing sections are slidably connected to the outer wall of the magnet frame 7, and the recycling trough 21 is slidably connected to the bottom of the multi-functional roller 9.
[0030] Specifically, the scraper section of the multi-functional roller 9 scrapes away the magnetic debris adsorbed on the drum screen 8, causing it to fall into the recycling tank 21 directly below. This facilitates the later extraction of the recycling tank 21 for the recycling and reuse of the metal and other magnetic debris, saving resources and costs. The load-bearing section of the multi-functional roller 9 limits and supports the magnet frame 7 and the drum screen 8, while ensuring the stability of their rotation.
[0031] Reference Figure 1The inner wall of the protective shell 1 is fixedly connected to a water collection tank 22, and the screen plate 10 is slidably connected to the top of the water collection tank 22. One end of a water pipe 13 is fixedly connected to the bottom of the water collection tank 22, and the other end of the water pipe 13 is fixedly connected to and passes through the top of the centrifuge 14.
[0032] Specifically, the water collection tank 22 is located directly below the sieve plate 10 to ensure that the mixed liquid flowing down from above can be completely received. After collection, the mixed liquid is transferred to the interior of the centrifuge 14 through the water pipe 13 below it for centrifugal separation of oil and water.
[0033] Reference Figure 4 The connecting block 18 is rotatably connected to the outer wall of the connecting rod 19, the outer wall of the valve core 20 is provided with a rubber sealing ring, and the float 16 is made of polypropylene.
[0034] Specifically, the connecting block 18 is rotatably connected to the outer wall of the connecting rod 19, ensuring that the connecting block 18 can rotate around the connecting rod 19 through the movement of the connecting rod 17 connected at the bottom, thereby driving the valve core 20 at the top to open and close the pipeline. The rubber sealing ring set on the outer wall of the valve core 20 ensures that the mixture will not leak and has corrosion resistance and wear resistance. The polypropylene material of the float 16 ensures that it is resistant to acids and alkalis, oil, and corrosion, and can float above the oil layer, thereby driving the movement of the connecting rod 17 and subsequent components through buoyancy.
[0035] Reference Figure 1 and Figure 3 The top of the protective shell 1 is fixedly connected to the feed inlet, the bottom of the feed inlet is located at the left end of the drum screen 8, the bottom of the centrifuge 14 and the separator 15 are both fixedly connected to and have drainage pipes running through them, and the top of the centrifuge 14 and the separator 15 are both fixedly connected to and have oil drain pipes running through them.
[0036] Specifically, oily wastewater enters the equipment through the feed inlet and is first discharged into the drum screen 8 from the left end opening. After treatment, it enters the subsequent components. The water treated by the centrifuge 14 and the separator 15 is discharged from the bottom drain pipe, while the oil floating on the upper layer flows through the upper oil drain pipe.
[0037] Working principle: When using this oil-water separator, the motor 2 is started, and the oil-water mixture containing debris from the rivet nut processing is discharged from the feed port into the drum screen 8. When the motor 2 starts, it drives the worm 3 to rotate. The worm 3 drives the worm wheel 4 to rotate through meshing. The worm wheel 4 is fixedly connected to the drive rod 5, so the drive rod 5 is driven to rotate. Multiple fixed rods 6 fixed to the drive rod 5 drive the magnet frame 7 and the drum screen 8 to rotate. Multiple neodymium magnets are embedded equidistantly inside the magnet frame 7. The drum screen 8 is mounted on the magnet frame. Once mounted on the frame 7, the entire drum becomes magnetic. Wastewater passes through the sieve holes on the drum screen 8 and falls into the lower sieve plate 10. Magnetic debris such as iron filings in the mixture is attracted to the drum. The sieve plate 10 has sieves with different sized holes fixedly installed in layers inside. After the wastewater falls onto the sieve plate 10, the debris inside remains on the sieves. After multiple layers of screening, the oil-water mixture continues to fall through the sieve holes into the water collection tank 22, and then enters the centrifuge 14 through the water pipe 13. The bottom end of the worm gear 3 is fitted with... The pulley 11 transmits power from the motor 2 to the rotating rod 12 connected to the input end of the centrifuge 14 via a belt, driving the centrifuge 14 to run. After the mixture undergoes centrifugal stratification inside the centrifuge 14, the upper oil layer enters the separator 15 through the water pipe 13 for gravity stratification. When the water level inside the separator 15 reaches the set standard, buoyancy causes the float 16 to rise with the water level. The lift is transmitted to the connecting block 18 via the connecting rod 17, causing the connecting block 18 to rotate around the connecting rod 19. The valve core 20 at the top of the moving connecting rod 19 slides along the inner wall of the water pipe 13, blocking the output pipe of the water pipe 13 and preventing the mixture from continuing to enter the separator 15. This facilitates the treatment of oil and water in the separator 15. Oil will flow out from the oil outlet pipe at the right end of the separator 15, and water will flow out from the water outlet pipe at the bottom end of the separator 15. When the water level inside the separator 15 drops, the float ball 16 drops, and through component linkage, it drives the valve core 20 to slide in the opposite direction, allowing the mixture to continue to enter the separator 15. This operation can be repeated.
[0038] The magnetic debris, such as iron filings, adsorbed on the drum screen 8 will be touched by the multi-functional roller 9 and fall into the recycling tank 21 below as the drum screen 8 rotates. After the separation is completed, the recycling tank 21 can be pulled out to recycle and reuse the iron filings, and the remaining debris can be recycled by pulling out the screen plate 10.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
