Description

Technical Field

[0001] This invention belongs to the field of multi-stage wastewater treatment technology, and in particular relates to a high-efficiency oil removal device for condiment production wastewater. Background Technology

[0002] During the production of condiments such as soy sauce, chili oil, and compound seasonings, industrial wastewater with complex composition, high concentration of organic matter, and rich in animal and vegetable oils is discharged. In modern environmental protection projects, the discharge of such wastewater in compliance with standards usually requires a rigorous multi-stage water treatment process.

[0003] In a multi-stage treatment chain, the oil removal pretreatment at the front end is crucial to the stable operation of the entire wastewater treatment system. If oil removal is incomplete, a large amount of grease will flow with the water into subsequent multi-stage treatment units, increasing the chemical dosing costs and treatment load of the physicochemical stage. Once grease enters the biological treatment tank, it will quickly adhere to the surface of the activated sludge, blocking the mass transfer process between microorganisms and oxygen and nutrients, leading to microbial suffocation or even system collapse.

[0004] Oil removal equipment commonly used in equalization tanks or grease traps of industrial multi-stage water treatment, such as fixed steel belt oil skimmers or oil separators, often have defects. The influent of multi-stage sewage systems often has peak and valley alternations. When concentrated sewage discharge causes a surge in oil concentration, traditional fixed oil removal equipment relies on the passive collection method of natural oil flow, which is extremely inefficient and cannot remove the thick oil layer on the surface in a short time. This can easily lead to excessive oil overflow into the next stage of biological treatment tank, forming a fatal shock load, indicating room for improvement. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the passive collection method of fixed oil removal equipment, which relies on the natural flow of oil, is extremely inefficient and cannot remove the thick oil layer on the surface in a short time. Therefore, this invention proposes a high-efficiency oil removal device for condiment production wastewater.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An efficient oil removal device for condiment production wastewater includes an oil removal tank, a pre-filter box connected to the front of the oil removal tank, an oil skimmer connected to the top side of the pre-filter box, and a position control mechanism, an oil scraping trough, an oil scraping mechanism, a lifting mechanism, and a drainage trough.

[0007] The position control mechanism includes a lifting plate, which is movably connected to the top of the degreasing tank; A main shaft is connected to the top of the oil scraping groove. The main shaft extends through the lifting plate to the top of the lifting plate. A drive motor is connected to the top of the lifting plate. The main shaft is connected to the drive motor. The oil is scraped off by the rotation of the oil scraping groove in the oil removal groove. The oil scraping mechanism is rotatably connected to the oil scraping groove. The oil scraping mechanism includes an oil scraping steel belt rotatably connected to the oil scraping groove, which removes surface oil by rotating the oil scraping steel belt. The lifting mechanism is connected to one side of the oil scraping mechanism, and the oil inside the oil scraping mechanism is lifted by the lifting mechanism. The drain trough has an annular structure and is connected to the bottom of the lifting plate. One side of the lifting mechanism extends into the drain trough through a pipe to drain the liquid, and the drain trough extends to the outside of the oil removal tank through a pipe to drain the liquid.

The drive rollers are rotatably connected to the inner cavity of the oil scraping groove. A base is provided outside the drive rollers, and the base is rotatably connected to the inner wall of the oil scraping groove. The drive unit is connected to the outside of the oil scraper groove. The output shaft of the drive unit passes through a through hole opened on the outside of the oil scraper groove and is connected to one side of the base. The rotation of the output shaft of the drive unit drives the oil scraper steel belt to deflect.

[0010] As a further description of the above technical solution: The oil scraping mechanism further includes: a stabilizing seat, a guide sleeve, and a first spring; A collar is rotatably connected to the inner cavity of the stabilizer seat, the collar is connected to one side of the base, and the top of the stabilizer seat is connected to the top of the inner cavity of the oil scraper groove; A guide sleeve is connected to the outside of the collar, and a guide rod is rotatably connected inside the guide sleeve. One end of the guide rod is connected to the outside of the collar, and the other end of the guide rod is connected to one side of the base. The first spring is sleeved outside the guide rod, and its two ends are connected to the guide sleeve and one end of the guide rod, respectively.

[0011] As a further description of the above technical solution: The guide rod axis is arc-shaped, the hole in the inner cavity of the guide sleeve is arc-shaped, and the guide rod slides within the hole of the guide sleeve.

[0012] As a further description of the above technical solution: The lifting mechanism includes an oil storage tank, an oil scraper, a fixed seat, a lifting steel belt, and an oil discharge tank; One side of the oil storage tank is connected to the oil outlet on one side of the oil scraper via a flexible cover; The oil scraper is connected to the bottom of the oil outlet side of the inner cavity of the oil scraper groove. One side of the oil scraper is in contact with the corresponding oil scraper steel strip. The oil scraper guides the oil absorbed by the oil scraper steel strip into the oil storage tank. The bottom sides of the fixed base are connected to the top of the oil storage tank via support plates; A lifting steel belt is inserted between the fixed seat and the oil storage tank. A drive shaft is rotatably connected to the inner cavity of the fixed seat, and one side of the lifting steel belt is connected to the outside of the drive shaft. The oil drain trough is connected to the outside of the fixed base. Both the oil drain trough and the fixed base have through slots on their opposite sides. An oil scraper is connected inside the oil drain trough. The oil scraper passes through the through slot and contacts one side of the lifting steel belt. The oil is lifted from the oil storage tank to the oil drain trough by rotating the drive shaft.

[0013] As a further description of the above technical solution: It also includes an oil drain pipe, which is connected to one side of the oil drain tank and extends to the drain tank at the other end.

[0014] As a further description of the above technical solution: It also includes a buffer mechanism connected between the lifting mechanism and the oil scraper groove, the buffer mechanism including a moving plate, a connecting plate and a second spring; Both sides of the bottom of the movable plate are connected to buffer rods, which are connected to the top of the oil scraper groove.

[0015] As a further description of the above technical solution: The connecting plate includes an integrally connected horizontal plate and a vertical plate, with the horizontal plate slidably connected to the outside of the buffer rod through a sliding hole, and the other end of the vertical plate connected to the top of the lifting mechanism.

[0016] As a further description of the above technical solution: It also includes baffles with a wavy cross-section. Multiple baffles are arranged in an array at the bottom of the oil removal tank to maintain the water retention effect and facilitate oil separation.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the position is adjusted by a position control mechanism, and the drive motor drives the main shaft to rotate the entire oil scraping tank within the oil removal tank. While the oil scraping steel belt is sucking up oil, it also performs a large-scale circumferential scraping motion on the liquid surface along with the oil scraping tank, which greatly increases the contact area between the steel belt and the oil. There is no need to wait for the oil to flow naturally, which multiplies the treatment effect of the large-area oil removal tank. This helps to intercept grease in the pretreatment stage and provides highly stable water for the subsequent physicochemical flotation and biological treatment units, ensuring the overall treatment effect of the multi-stage treatment system.

[0018] 2. In this invention, by introducing a guide rod, a guide sleeve, and a first spring into the oil scraping mechanism, when the liquid surface ripples slightly, the elastic force of the first spring can absorb the impact, causing the base to drive the steel belt to produce a slight deflection that adapts to the environment, always maintaining contact with the oil surface. This ensures both precise scraping of thin layers of oil without carrying water and efficient adhesion to thick layers of oil. A buffer mechanism consisting of a buffer rod, a sliding hole connecting plate, and a second spring is installed between the lifting mechanism and the oil scraping groove to absorb the relative longitudinal displacement between the oil storage tank and the oil scraping groove, preventing secondary agitation of the water surface caused by synchronous rigid movement and ensuring the smoothness of oil transfer.

[0019] 3. In this invention, to solve the technical bottleneck of difficult drainage of the rotating mechanism, the oil collected by the scraper steel belt is first scraped into the rotating oil storage tank, and then the oil is lifted to a high position by the lifting steel belt with a larger internal diameter. The oil falls precisely into the drainage tank with a circular cross section through the drain pipe. The annular drainage tank design matches the circumferential rotation of the scraper mechanism. No matter what angle the scraper mechanism rotates to, the drain pipe can drain the oil into the tank and finally out of the equipment, realizing continuous and uninterrupted oil drainage under rotating conditions.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-11 The present invention provides a technical solution: an efficient oil removal device for condiment production wastewater, including an oil removal tank 1, a pre-filter box 2 provided on the front side of the oil removal tank 1, the pre-filter box 2 being connected to the oil removal tank 1, an oil skimmer being connected to one side of the top of the inner cavity of the pre-filter box 2, and further including: a position control mechanism 3, an oil scraping trough 5, an oil scraping mechanism 6, a lifting mechanism 7, and a drain trough 9.

[0024] The position control mechanism 3 includes a lifting plate 301, which is movably connected to the top of the degreasing tank 1; The top of the oil scraper 5 is connected to a main shaft, which extends through the lifting plate 301 to the top of the lifting plate 301. The top of the lifting plate 301 is connected to a drive motor 4, and the main shaft is connected to the drive motor 4. The oil is scraped off by the rotation of the oil scraper 5 in the oil removal tank 1. The oil scraping mechanism 6 is rotatably connected to the oil scraping groove 5. The oil scraping mechanism 6 includes an oil scraping steel belt 601 rotatably connected to the oil scraping groove 5. The oil scraping steel belt 601 is rotated to remove surface oil. The lifting mechanism 7 is connected to one side of the oil scraping mechanism 6, and the oil inside the oil scraping mechanism 6 is lifted by the lifting mechanism 7. The drain trough 9 has an annular trough structure. The drain trough 9 is connected to the bottom of the lifting plate 301. One side of the lifting mechanism 7 extends into the drain trough 9 through a pipe to drain the liquid. The drain trough 9 extends to the outside of the oil removal tank 1 through a pipe to drain the liquid.

[0025] Please see Figures 1-2 The position control mechanism 3 includes a lifting cylinder 302 and a linear module 304; Two lifting cylinders 302 are respectively connected to both sides of the lifting plate 301. The top of the lifting cylinder 302 is connected to the mounting base 303, and the mounting base 303 is slidably connected to the outside of the oil removal tank 1. Two linear modules 304 are connected to the outside of the degreasing tank 1 on both sides, and the mounting base 303 is connected to the top of the movable end of the linear module 304; Please see Figure 11 The oil scraping mechanism 6 also includes a drive roller 602 and a drive unit 607; Two drive rollers 602 are respectively located on both sides of the inner side of the oil scraping steel belt 601. The drive rollers 602 are rotatably connected to the inner cavity of the oil scraping groove 5. A base 608 is provided outside the drive rollers 602. The base 608 is rotatably connected to the inner wall of the oil scraping groove 5. The drive unit 607 is connected to the outside of the oil scraper groove 5. The output shaft of the drive unit 607 passes through the through hole opened on the outside of the oil scraper groove 5 and is connected to one side of the base 608. The output shaft of the drive unit 607 rotates to drive the oil scraper steel belt 601 to deflect. To avoid the problem of traditional steel belt oil removal equipment having a narrow coverage area and requiring time for the oil to flow on the water surface, the following measures are taken: The designed oil scraping mechanism 6 can drive the main shaft and oil scraping groove 5 to rotate through the output shaft of the drive motor 4. When the oil scraping groove 5 rotates, the bottom oil scraping steel belt 601 can adhere to the oil floating on the surface, and the rotation of the oil scraping steel belt 601 can transport the oil to the lifting mechanism 7 on one side. After being lifted by the lifting mechanism 7, the oil is discharged. The rotatable oil scraping groove 5, together with the continuous transmission of the oil scraping steel belt 601, improves the oil discharge treatment effect of the large-area oil removal groove 1.

[0026] Please see Figure 11 The oil scraping mechanism 6 also includes: a stabilizing seat 603, a guide sleeve 609, and a first spring 606; A collar 604 is rotatably connected to the inner cavity of the stabilizer 603. The collar 604 is connected to one side of the base 608, and the top of the stabilizer 603 is connected to the top of the inner cavity of the oil scraper groove 5. The guide sleeve 609 is connected to the outside of the collar 604. A guide rod 605 is rotatably connected inside the guide sleeve 609. One end of the guide rod 605 is connected to the outside of the collar 604, and the other end of the guide rod 605 is connected to one side of the base 608. The first spring 606 is sleeved on the outside of the guide rod 605, and the two ends of the first spring 606 are respectively connected to the guide sleeve 609 and one end of the guide rod 605; Among them, the axis of the guide rod 605 is arc-shaped, the hole in the inner cavity of the guide sleeve 609 is arc-shaped, and the guide rod 605 slides in the hole of the guide sleeve 609; Furthermore, in order to reduce the interference of the oil scraper belt 601 with the liquid surface during rotation, when the liquid surface fluctuates, the oil scraper belt 601 can drive the collar 604 through the base 608 to drive the guide sleeve 609 to rotate outside the guide rod 605. The rotation of the guide sleeve 609 can squeeze the first spring 606 on one side. The first spring 606 can absorb the liquid surface fluctuation with its own elasticity, avoiding the oil scraper belt 601 from leaving the oil surface due to fluctuation, which would cause the oil-water interface to become disordered, and improving the oil scraping adaptability to thin liquid surfaces.

[0027] Please see Figures 6-8 The lifting mechanism 7 includes an oil storage tank 701, an oil scraper 707, a fixed seat 702, a lifting steel belt 703, and an oil discharge tank 704. One side of the oil storage tank 701 is connected to the oil outlet on one side of the oil scraper 5 via a flexible cover; The oil scraper 707 is connected to the bottom of the oil outlet side of the inner cavity of the oil scraper 5. One side of the oil scraper 707 is in contact with the corresponding position of the oil scraper steel strip 601. The oil scraper 707 draws oil from the oil scraper steel strip 601 and guides it into the oil storage tank 701. The bottom sides of the fixed base 702 are connected to the top of the oil storage tank 701 via support plates 706; The lifting steel belt 703 is inserted between the fixed seat 702 and the oil storage tank 701. The inner cavity of the fixed seat 702 is rotatably connected to the drive shaft, and one side of the lifting steel belt 703 is driven to the outside of the drive shaft. The oil drain trough 704 is connected to the outside of the fixed base 702. Both the oil drain trough 704 and the fixed base 702 have through slots on their opposite sides. An oil scraper is connected inside the oil drain trough 704. The oil scraper passes through the through slot and contacts one side of the lifting steel belt 703. The oil is lifted from the oil storage tank 701 to the oil drain trough 704 by the rotation of the drive shaft. It also includes an oil drain pipe 705, which is connected to one side of the oil drain tank 704 and the other end of the oil drain pipe 705 extends to the drain tank 9; To avoid the problem of insufficient oil removal caused by the rotating oil scraping mechanism 6, specifically: when the oil adhering to the oil scraping steel belt 601 can be scraped and guided into the oil storage tank 701 by the oil scraping plate 707, the continuously installed lifting steel belt 703 can lift the oil in the oil storage tank 701 to the fixed seat 702 like a traditional fixed steel belt oil scraper, and scrape the oil through the oil scraping strip in the fixed seat 702 into the oil discharge tank 704 and discharge it into the drain trough 9 through the oil discharge pipe 705. The surrounding drain trough 9 can adapt to the rotating oil scraping and discharge needs of the oil scraping tank 5, and improve the oil scraping treatment effect; Furthermore, the diameter of the lifting steel belt 703 located inside the oil storage tank 701 is slightly larger, which can fully adhere to the oil in the oil storage tank 701 and improve the lifting effect of a large amount of oil.

[0028] Please see Figures 6-7 It also includes a buffer mechanism 8, which is connected between the lifting mechanism 7 and the oil scraper 5. The buffer mechanism 8 includes a moving plate 802, a connecting plate 804 and a second spring 803. Both sides of the bottom of the movable plate 802 are connected to buffer rods 801. The buffer rods 801 are connected to the top of the oil scraper groove 5. The second spring 803 is sleeved on the outside of the buffer rods 801. The two ends of the second spring 803 are respectively connected to the corresponding positions on one side of the movable plate 802 and the connecting plate 804. The connecting plate 804 is slidably connected to the outside of the buffer rod 801, and the connecting plate 804 is connected to the top of the lifting mechanism 7; The vertical plate is connected to the top of the oil storage tank 701; With the buffer mechanism 8 in place, when the liquid level fluctuates, the oil storage tank 701 can slide outside the buffer rod 801 via the connecting plate 804. When the connecting plate 804 slides, it can squeeze the external second spring 803. The second spring 803 can absorb the shaking and displacement of the oil storage tank 701. It can absorb the liquid level fluctuation through the longitudinal displacement of the oil storage tank 701 relative to the oil scraping groove 5, so as to maintain the delivery of the oil scraped by the oil scraping mechanism 6 to the lifting mechanism 7. Furthermore, by separating the oil scraping groove 5 and the lifting mechanism 7, the synchronous movement can avoid interference with the liquid level of the subsequent stroke.

[0029] Please see Figure 1 It also includes: a baffle plate 10, the baffle plate 10 having a wavy cross-sectional shape, and multiple baffle plates 10 arrayed at the bottom of the inner cavity of the oil removal tank 1, the baffle plate 10 maintaining the water retention effect to facilitate oil separation.

[0030] A wave-shaped baffle plate 10 is arranged in an array at the bottom of the inner cavity of the oil removal tank 1, which effectively disrupts the turbulent tendency of the bottom water flow and plays an excellent role in stabilizing and rectifying the flow. The residence time of the water at the bottom is extended, and the water body remains in a relatively static state. The density difference greatly promotes the floating and separation of fine oil droplets.

[0031] Working principle: During use, water enters and is initially intercepted. The oily wastewater first enters the pre-filter tank 2, where larger solid impurities are intercepted. The oil skimmer at the top of the pre-filter tank 2 initially removes large floating oil particles. The wastewater then flows into the main oil removal tank 1. The wave-shaped baffle 10 at the bottom of the oil removal tank 1 stabilizes the water flow, keeping the water body stable. The difference in gravity accelerates the oil to float to the surface.

[0032] After the device is started, the linear module 304 drives the mounting base 303 to adjust its horizontal position, and the lifting cylinder 302 drives the lifting plate 301 to adjust its height, so that the oil scraping mechanism 6 is accurately lowered to the oil-water interface. The drive motor 4 at the top of the lifting plate 301 starts, driving the main shaft and the oil scraping groove 5 to rotate above the liquid surface. The drive unit 607 in the oil scraping groove 5 drives the drive roller 602 to rotate, so that the oil scraping steel belt 601 starts to rotate in a cycle. While the oil scraping steel belt 601 absorbs the surface oil by rotating on its own, it actively scrapes the large area of ​​liquid surface with the revolution of the oil scraping groove 5, thereby improving the oil scraping coverage.

[0033] When the oil scraper 5 rotates and external water flow causes liquid surface fluctuations, the bottom end of the oil scraper steel belt 601 is impacted by the buoyancy of the water waves. The base 608 drives the collar 604 to deflect on the arc-shaped guide rod 605 and squeeze the first spring 606. The first spring 606 uses its own elastic potential energy to absorb the impact force of the fluctuations, so that the oil scraper steel belt 601 always closely fits or follows the fluctuating liquid surface like a suspension system, preventing the steel belt from detaching from the oil layer or penetrating the water layer.

[0034] The oil adhering to the scraper belt 601 moves upward with the belt, is scraped off by the scraper plate 707 and guided into the oil storage tank 701. During this transfer process, if mechanical shaking occurs, the connecting plate 804 in the buffer mechanism 8 slides on the buffer rod 801 and compresses the second spring 803 to absorb the relative vibration between the oil storage tank 701 and the scraper trough 5, ensuring that the oil is transferred smoothly without splashing.

[0035] The oil that falls into the oil storage tank 701 is lifted again by the lifting steel belt 703 with a larger diameter at the lower end to the fixed seat 702. The oil scraper in the fixed seat 702 scrapes the oil on the lifting steel belt 703 into the oil drain tank 704, and then flows down along the oil drain pipe 705. Since the outermost drain tank 9 is a circular ring structure, when the oil drain pipe 705 rotates 360 degrees with the main shaft, its outlet end is always located directly above the circular drain tank 9. The oil falls smoothly into the drain tank 9 and is finally discharged through the external pipe, completing the automatic oil removal operation.
