Description

Technical Field

[0001] This utility model belongs to the field of oil-liquid separation technology, and in particular relates to a two-way oil-liquid separation device. Background Technology

[0002] Oil separation refers to the process of separating oily substances from water, solid impurities and other pollutants in a mixture through physical or chemical methods. Its core functions are: resource recovery, environmental protection and equipment protection. In the fields of machinery manufacturing, petrochemicals, food processing, and shipping, oil separation technology is widely used in the following scenarios: cutting fluid purification, oily wastewater treatment and waste oil regeneration.

[0003] Current mainstream oil-liquid separation equipment has the following limitations: it can only complete the initial oil-liquid separation, and the separated oil still contains small particles, emulsions or colloids, which require secondary treatment by external filtration equipment before it can be reused. This leads to a complex process and increased energy consumption. During the separation process, impurities are easily deposited and clog the filter screen or pipes, requiring frequent shutdowns for cleaning, which affects continuous production. To address these issues, we provide a two-way oil-liquid separation equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a two-way oil-liquid separation device. By using an oil separator in conjunction with a filtration mechanism, it solves the problem that existing oil-liquid separation devices are prone to impurities accumulating and clogging the filter screen or pipes during the separation process, requiring frequent shutdowns for cleaning and affecting continuous production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a bidirectional oil-liquid separation device, comprising a separation tank, a slag discharge mechanism on one side of the separation tank, a liquid discharge mechanism on the rear side of the separation tank, an oil-liquid separation mechanism inside the separation tank, and a filtration mechanism at the bottom of the separation tank. The oil-liquid separation mechanism includes a float ball disposed inside the separation tank, a movable block fixedly connected to one side of the float ball, a fixed block fixedly connected to one side of the movable block, a filter ring disposed inside the fixed block, a first scraper fixedly connected inside the fixed block, and a separation pipe communicating with the bottom of the filter ring. The filtration mechanism includes a drive assembly disposed at the bottom of the separation tank, a filter box fixedly connected to the bottom of the separation tank, a filter screen disposed inside the filter box, a second scraper contacting the top of the filter screen, and an electromagnet fixedly connected to the bottom of the filter box.

[0007] The present invention is further configured such that a vertical rod is fixedly connected inside the separation box, and a sliding through hole adapted to the vertical rod is opened inside the movable block. The vertical rod is located inside the sliding through hole, and there are four floats, four movable blocks, and four vertical rods.

[0008] The present invention is further configured such that an oil inlet groove is provided on the surface of the fixed block, the number of the first scrapers is four, and the top of the filter ring is movably connected to the inside of the fixed block through a sealed bearing.

[0009] The present invention is further configured such that the separation tube is movably connected to the separation box via a bearing, and a sealed box door is provided on the front side of the filter box.

[0010] The present invention is further configured such that the driving assembly includes a driving motor fixedly connected to the bottom of the separation box, a driving gear fixedly connected to the output end of the driving motor, a driven gear meshing with the driving gear, and a rotating gear meshing with the driven gear. The driven gear is fixedly connected to the surface of the separation tube, and the rotating gear is movably connected to the separation box through a bearing.

[0011] The present invention is further configured such that an oil inlet plate is connected to the left side of the filter box, the separation pipe is located at the top of the oil inlet plate, and the separation pipe is located inside the separation box and is designed to be retractable.

[0012] The present invention is further configured such that an oil drain pipe is connected to the bottom of the filter box, and a connecting rod is fixedly connected to the top of the second scraper.

[0013] The present invention has the following beneficial effects.

[0014] 1. This invention utilizes a float that moves with the oil level, causing a movable block to slide up and down along a vertical rod. The movable block, in conjunction with a fixed block, adjusts the longitudinal position of the oil separation mechanism, ensuring the filter ring is precisely immersed in the oil layer. The drive assembly, through the meshing of a drive gear and a driven gear, continuously rotates the separation tube and filter ring. Simultaneously, a first scraper inside the fixed block dynamically scrapes and cleans the surface of the rotating filter ring. This process achieves the dual functions of adaptive positioning of the oil interface and self-cleaning of the filter assembly, effectively preventing impurities from accumulating and clogging the filter ring surface, improving the primary oil separation efficiency, and eliminating the need to stop the machine for cleaning the filter device.

[0015] 2. In this invention, after the primary separated oil is introduced into the filter box through the separation pipe, the rotating gear of the drive component drives the second scraper to move in a circular motion on the surface of the filter screen via the connecting rod, continuously scraping away impurities on the surface of the filter screen to the edge accumulation area; at the same time, the electromagnet generates a directional adsorption effect on the ferromagnetic particles in the oil. This linkage design reduces the clogging rate of the filter screen pores, and combined with the electromagnetic adsorption module, forms a physical-magnetic dual purification mechanism. Finally, the cleanliness of the oil output from the drain pipe meets the standard for reuse, realizing integrated continuous operation of the oil separation and filtration process, reducing the equipment investment and energy consumption of secondary filtration in traditional processes.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figures 1-5 This utility model relates to a bidirectional oil-liquid separation device, comprising a separation tank 1, a slag discharge mechanism 2 on one side of the separation tank 1, a liquid discharge mechanism on the rear side of the separation tank 1, an oil-liquid separation mechanism 3 inside the separation tank 1, and a filter mechanism 4 at the bottom of the separation tank 1. The oil-liquid separation mechanism 3 includes a float 301 disposed inside the separation tank 1, a movable block 302 fixedly connected to one side of the float 301, a fixed block 303 fixedly connected to one side of the movable block 302, and a filter ring 304 disposed inside the fixed block 303 and fixedly connected to the fixed block 304. The first scraper 305 inside the 03 and the separation tube 306 connected to the bottom of the filter ring 304, the filter mechanism 4 includes a drive assembly 401 disposed at the bottom of the separation box 1, a filter box 402 fixedly connected to the bottom of the separation box 1, a filter screen 403 disposed inside the filter box 402, a second scraper 404 in contact with the top of the filter screen 403, and an electromagnet 405 fixedly connected to the bottom of the filter box 402. The electromagnet 405 is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0027] Specifically, through the oil separation mechanism 3, the float 301 floats according to the oil level, causing the movable block 302 to slide up and down along the vertical rod 5, adjusting the position of the fixed block 303. Oil enters through the oil inlet groove on the surface of the fixed block 303, and after being filtered by the rotating filter ring 304, impurities are scraped off by the first scraper 305. The filtered oil flows into the separation pipe 306. The drive assembly 401 drives the separation pipe 306 to rotate through the gear set, and the separation pipe 306 drives the filter ring 304 to rotate, so that the first scraper 305 can continuously clean the surface of the filter ring 304, avoiding... The filter ring 304 is designed to prevent impurities from clogging. Through the filter mechanism 4, the oil discharged from the separation pipe 306 enters the filter box 402, where it is filtered by the filter screen 403 to intercept tiny particles. The drive component 401, via the rotating gear 4014, drives the second scraper 404 to rotate continuously, scraping away impurities from the surface of the filter screen 403 until they accumulate at the edges. An electromagnet 405 adsorbs metal particles in the oil. The filtered oil is discharged through the drain pipe 7. The oil separation mechanism 3 completes the primary separation, while the filter mechanism 4 performs deep purification. Both are automated through the linkage of the drive component 401. This dual cleaning mechanism of the rotating separation pipe 306 and the scraper movement solves the problems of easy filter clogging and frequent shutdowns required in traditional equipment, achieving efficient and continuous bidirectional oil separation. Specific Implementation Example 2

[0029] Please see Figures 1-5 Based on the first specific embodiment, a vertical rod 5 is fixedly connected inside the separation box 1. A sliding through hole adapted to the vertical rod 5 is opened inside the movable block 302, and the vertical rod 5 is located inside the sliding through hole. There are four floats 301, four movable blocks 302, and four vertical rods 5. An oil inlet groove is opened on the surface of the fixed block 303. There are four first scrapers 305. The top of the filter ring 304 is movably connected to the inside of the fixed block 303 via a sealed bearing. The separation pipe 306 is movably connected to the separation box 1 via a bearing. A sealed box door is provided on the front side of the filter box 402. The drive assembly 401 includes a drive motor 4011 fixedly connected to the bottom of the separation box 1. The drive motor 4011 is existing technology and will not be described in detail in this solution. The technical personnel in the field can clearly understand the working principle. The drive gear 4012 is fixedly connected to the output end of the drive motor 4011. The driven gear 4013 meshes with the drive gear 4012. The rotating gear 4014 meshes with the driven gear 4013. The driven gear 4013 is fixedly connected to the surface of the separator tube 306. The rotating gear 4014 is movably connected to the separator box 1 through a bearing. The left side of the filter box 402 is connected to the oil inlet plate 6. The separator tube 306 is located on the top of the oil inlet plate 6. The separator tube 306 is located inside the separator box 1 and is designed to be retractable. The bottom of the filter box 402 is connected to the oil drain pipe 7. The top of the second scraper 404 is fixedly connected to the connecting rod 8. The top of the connecting rod 8 is fixedly connected to the rotating gear 4014.

[0030] Specifically, the vertical rod 5 limits the movement of the movable block 302, allowing it to move vertically up and down. The oil inlet groove allows oil to enter the fixed block 303 and flow into the separator pipe 306 through the filter holes on the filter ring 304. The sealed door allows for periodic cleaning of the filter screen 403. The drive assembly 401 drives the separator pipe 306 and the second scraper 404 to rotate continuously. The oil inlet plate 6 allows oil falling from the separator pipe 306 to enter the filter box 402. The telescopic separator pipe 306 allows it to move up and down with the fixed block 303 and the filter ring 304. The oil drain pipe 7 discharges the filtered oil. The connecting rod 8 allows the rotating gear 4014 to drive the second scraper 404 to rotate continuously.

[0031] The operation process of this embodiment is as follows: The oil to be separated is placed in the separation tank 1. Under the action of the float ball 301, the movable block 302 is moved up to the oil layer. The movable block 302 drives the fixed block 303 to float up to the oil layer. At this time, the filter ring 304 is located at the oil layer. The oil flows into the separation tube 306 through the filter hole of the filter ring 304. During the separation process, the drive motor 4011 drives the drive gear 4012 to rotate. The drive gear 4012 drives the driven gear 4013 and the rotating gear 4014 to rotate. The driven gear 4013 drives the separation tube 306 and the filter ring 304 to rotate continuously. During the separation of oil, the first scraper 305 continuously scrapes the surface of the filter ring 304 to prevent impurities from clogging the filter hole.

[0032] The oil sludge at the separation point falls through the separation pipe 306 to the oil inlet plate 6, and flows into the filter box 402. The filter screen 403 in the filter box 402 performs secondary fine filtration on the oil sludge. During the filtration process, the rotating gear 4014 drives the second scraper 404 to rotate continuously on the surface of the filter screen 403 through the connecting rod 8, scraping off the impurities on the surface of the filter screen 403 to the edge accumulation, so that the filter screen 403 always maintains a good filtration effect. During the fall of the filtered oil, it comes into contact with the electromagnet 405. The electromagnet 405 adsorbs the metal impurities in the oil, and finally the oil is separated and discharged out through the oil drain pipe 7.
