Description

Technical Field

[0001] This invention relates to the field of oil storage tank technology, specifically to an oil storage tank for chicken fat. Background Technology

[0002] Oil storage tanks, also known simply as oil tanks or storage tanks, are large containers with relatively regular shapes used to store oil products. Oil storage tanks are mainly classified by structure into crude oil storage tanks, fuel oil storage tanks, lubricating oil tanks, and animal and vegetable oil storage tanks, etc.

[0003] Current technology for storing large quantities of chicken fat requires the use of animal and vegetable oil storage tanks to store the processed chicken fat. Chicken fat contains various substances, such as triglycerides, free fatty acids, phospholipids, and other trace components. These substances have different densities. Generally, triglycerides have a relatively low density, while some impurities, water, and free fatty acids have a higher density. Under the influence of gravity, substances with different densities will gradually separate into layers; the less dense substances will float, and the more dense substances will sink. After a long period of settling, chicken fat will separate into layers. The upper layer of chicken fat is a relatively pure layer of oil, while the lower layer will accumulate some denser impurities and water. In addition, at high temperatures, some components that were originally dissolved in the oil will precipitate out as the temperature decreases, leading to further separation.

[0004] Because of the different densities and compositions of the layers, separated chicken fat may require larger storage containers. This not only increases storage costs but also occupies more warehouse space. Furthermore, separation causes changes in the chemical composition of the chicken fat; impurities or moisture in the lower layer can promote microbial growth, producing a rancid or other off-flavor. Additionally, aldehydes, ketones, and other substances produced by oxidation reactions also have distinctive odors that can affect the original aroma of the chicken fat.

[0005] In response, we propose a storage tank for chicken fat to solve the above problems. Summary of the Invention

[0022] Beneficial effects

[0023] Compared with the prior art, the present invention provides an oil storage tank for chicken fat, which has the following beneficial effects:

[0024] The continuously rotating agitator blades inside the oil storage tank agitate the chicken fat stored there. This rotation ensures thorough mixing of the chicken fat in different parts of the tank. Continuous agitation also allows the chicken fat to come into full contact with air, accelerating oxygen consumption and renewal, and reducing oxidation caused by excessively high local oxygen concentrations. Furthermore, the constant movement of the agitator blades keeps the chicken fat in motion, reducing its residence time and adhesion to the tank walls. This prevents the formation of a thick deposit layer, lowering the risk of corrosion due to long-term adhesion.

[0025] Furthermore, the rotating impeller continuously vibrates, breaking up any localized accumulation or agglomeration of chicken fat during the mixing process. When the impeller is stationary or rotating smoothly, some components in the chicken fat may clump together due to intermolecular forces, forming larger clumps. Vibration continuously disperses these clumps, ensuring that all parts of the chicken fat are thoroughly stirred and mixed. In addition, continuous vibration makes the flow of chicken fat in the storage tank smoother. When the impeller rotates, the surface vibration creates a "micro-disturbance" effect, disrupting the originally stable flow structure of the chicken fat and creating more eddies and turbulence. This change in flow state increases the contact area and relative speed between the chicken fat and the impeller, thereby improving mixing efficiency.

[0026] By vertically arranging stirring blades with different rotation speeds and opposite directions, along with a small stirring paddle, the different speeds and directions of the stirring components can create complex and diverse flow patterns within the oil storage tank. The faster-moving small stirring paddle generates a large centrifugal force, throwing the chicken oil from the center outwards, allowing it to quickly diffuse throughout the entire tank space. Conversely, the slower-moving stirring blades in the opposite direction push the chicken oil inwards as it diffuses outwards, preventing localized accumulation or sedimentation within the tank. Furthermore, when the two stirring components with different motion states act simultaneously, a relative velocity difference and shear force are created between them. This shear force breaks down large molecular clusters within the chicken oil into smaller particles, dispersing them more evenly throughout the oil.

[0027] By incorporating the scraper blade and connecting spring, when cleaning crystals precipitated on the inner wall of the oil storage tank, the scraper blade, under pressure from the more adhesive crystals, will displace upwards or downwards. When the scraper blade is displaced under pressure, its effective range is no longer limited to a fixed plane or trajectory. This upward or downward displacement allows the scraper blade to better conform to the curved and irregular parts of the tank's inner wall, ensuring effective cleaning of all areas. Furthermore, the adhesion of crystals to the tank's inner wall may vary; some crystals have strong adhesion and ordinary scraping motion may not be able to completely remove them. When the scraper blade is displaced under greater pressure, it can apply greater pressure to the crystals, thereby overcoming strong adhesion and removing stubborn crystals from the tank's inner wall.

[0028] The reciprocating extrusion mechanism helps to unclog the oil outlet, preventing thickened chicken fat from accumulating and affecting its flow. Smooth oil flow is crucial during storage and use. When the outlet is blocked by thickened chicken fat, the flow will be uneven, sometimes fast, sometimes slow, or even stop completely. The reciprocating motion of the extrusion mechanism helps to clear the blockage promptly, ensuring a stable flow of oil.

[0029] By using a reflux pipe and oil pump, chicken fat stored inside the oil storage tank can be extracted without air contact and then returned to the tank. During long-term storage, chicken fat may separate due to density differences or other factors. The reflux operation ensures thorough mixing and agitation of the chicken fat within the storage tank, eliminating separation and making more efficient use of the tank's space. Furthermore, the uniformly distributed chicken fat facilitates subsequent extraction and use, improving production and operational efficiency.

[0030] By using agitator blades and rotating blades, the chicken fat will collide and come into contact with the agitator blades during the reflux process. Some antioxidants, preservatives or other functional ingredients need to be added to the chicken fat. The agitation and the collision between the chicken fat and the rotating blades can accelerate the diffusion and distribution of these additives in the chicken fat, making them evenly dispersed throughout the oil and thus better exerting their effects.

[0061] Further embodiments

[0062] Please see Figure 1 , Figure 2 and Figure 7 The oil storage tank for chicken fat also includes a reflux assembly located below the oil outlet 15;

[0063] The reflux assembly includes a connecting pipe 51 fixedly connected to the reflux port 13, a support block 52 fixedly connected to the outer surface of the connecting pipe 51, an oil pump 53 fixedly connected to the end of the connecting pipe 51 away from the reflux port 13, and a rotating blade 54 rotatably connected to the inner wall of the top of the oil storage tank 11.

[0064] Among them, the support block 52 is fixedly connected to the outer wall of the oil storage tank 11 at the end away from the connecting pipe 51, the oil pump 53 is detachably fixedly installed at the bottom of the oil outlet 15 at the end away from the connecting pipe 51, and the rotating blade 54 is set above the stirring blade 23.

[0065] The overall working process and principle of the above embodiments are as follows:

[0066] Storage of chicken fat:

[0067] The staff first fixed the processed chicken oil to be stored through the pipe and the oil inlet 14, and then injected it into the oil storage tank 11 through the oil inlet 14. After filling, the pipe and the oil inlet 14 were disassembled to separate them. Then the oil inlet 14 was sealed, and the chicken oil was stored.

[0068] Stirring the chicken fat:

[0069] Chicken fat naturally contains a certain amount of water. When left to stand for a long time, the water will gradually sink to the bottom, creating a distinct oil-water separation. The upper layer is the fat, usually pale yellow or yellow, while the lower layer is a mixture of water and other impurities. Therefore, chicken fat needs to be stirred regularly to prevent this separation during long-term storage.

[0070] At this time, the staff starts the stepper motor 21 through the external controller. Since the output shaft end of the stepper motor 21 is fixedly connected to the drive shaft 22 through one end of the oil storage tank 11, the start of the stepper motor 21 will cause the drive shaft 22 to rotate inside the oil storage tank 11. At this time, the stirring blade 23, which is vertically slidably connected to the outer surface of the drive shaft 22, will rotate accordingly to stir the chicken oil stored in the oil storage tank 11.

[0071] It should be noted that during the above process, when the stirring blade 23 rotates, it will drive the hemispherical block 26 fixedly connected to its bottom end to rotate synchronously. Since the hemispherical block 2702 is located below the hemispherical block 26 and is located on the movement trajectory of the hemispherical block 26, when the hemispherical block 2702 cannot move vertically under the restriction of the limiting sleeve 2701, the hemispherical block 26 will come into contact with the hemispherical block 2702 as the stirring blade 23 rotates. As the stirring blade 23 continues to rotate, the hemispherical block 26 and the hemispherical block 2702 will continuously maintain the two states of contact and separation. Under the combined action of the hemispherical block 26 and the hemispherical block 2702, the stirring blade 23 will make vertical reciprocating motion on the outer surface of the driving rotation. During the movement of the stirring blade 23, it will continuously compress the limiting spring 25 set between the stirring blade 23 and the limiting ring 24.

[0072] By continuously rotating the stirring blades 23, the stirring blades 23 rotate inside the oil storage tank 11, stirring the chicken oil stored in the oil storage tank 11. The rotation of the stirring blades 23 can fully mix the chicken oil in different parts of the oil storage tank. Continuous stirring can make the chicken oil come into full contact with the air, accelerating the consumption and renewal of oxygen, reducing the oxidation reaction caused by excessive local oxygen concentration. In addition, the rotation of the stirring blades 23 can keep the chicken oil in a state of continuous movement, reducing the residence time and adhesion opportunities of the chicken oil on the tank wall. This can prevent the formation of a thick deposit layer on the tank wall and reduce the risk of tank wall corrosion caused by long-term adhesion.

[0073] Furthermore, the stirring blade 23 continuously vibrates during rotation. This continuous vibration breaks up any localized accumulation or agglomeration of chicken fat during the stirring process. When the stirring blade 23 is stationary or rotating relatively smoothly, some components in the chicken fat may clump together due to intermolecular forces, forming larger clumps. Vibration continuously disperses these clumps, ensuring that all parts of the chicken fat are thoroughly stirred and mixed. In addition, continuous vibration makes the flow of chicken fat in the storage tank smoother. When the stirring blade 23 rotates, the vibration on its surface generates a "micro-disturbance" effect, disrupting the originally relatively stable flow structure of the chicken fat and creating more eddies and turbulence. This change in flow state increases the contact area and relative speed between the chicken fat and the stirring blade 23, thereby improving stirring efficiency.

[0074] As the drive shaft 22 rotates, the driven gear 2707, which is fixedly connected to the bottom end of the drive shaft 22, will rotate synchronously. Through the meshing gear 2706, which is set between the rotating gear 2704 and the driven gear 2707 and meshes with both, the rotating gear 2704 will rotate on the outer surface of the drive shaft 22. At this time, the limiting sleeve 2701, which is fixedly connected to the upper surface of the rotating gear 2704, will rotate accordingly.

[0075] Since the number of teeth of the driven gear 2707 is greater than the number of teeth of the rotating gear 2704, the driven gear 2707 is connected to the rotating gear 2704 through the meshing gear 2706. Therefore, the rotation speed of the rotating gear 2704 will be faster than that of the driven gear 2707. At this time, the limiting sleeve 2701 fixedly connected to the driven gear 2707 and the small stirring paddle 2703 fixedly connected to the limiting sleeve 2701 will rotate synchronously, and the rotation speed of the small stirring paddle 2703 is faster than that of the stirring blade 23.

[0076] Furthermore, due to the meshing arrangement of the rotating gear 2704, the meshing gear 2706, and the driven gear 2707, when the drive shaft 22 drives the stirring blade 23 and the driven gear 2707 to rotate clockwise, the rotating gear 2704 and the small stirring blade 2703 will rotate counterclockwise under the transmission action of the meshing gear 2706, and the rotation speed of the small stirring blade 2703 is greater than the rotation speed of the stirring blade 23.

[0077] By vertically arranging stirring blades 23 and small stirring blades 2703 with different rotation speeds and opposite directions, the stirring components with different speeds and rotation directions can form complex and diverse flow patterns within the oil storage tank. The faster-moving small stirring blade 2703 can generate greater centrifugal force, throwing the chicken oil from the center outwards, allowing it to quickly diffuse throughout the entire tank space. Meanwhile, the slower-moving stirring blades 23, rotating in the opposite direction, can push the chicken oil inwards as it diffuses outwards, thus preventing local accumulation or sedimentation of the chicken oil within the oil storage tank 11. Furthermore, when the two stirring components with different motion states act simultaneously, a relative velocity difference and shear force are formed between them. This shear force can break down large molecular clusters in the chicken oil into smaller particles, dispersing them more evenly within the chicken oil.

[0078] With the driven gear 2707 and the driven shaft 31 fixedly connected, the driven shaft 31 will rotate inside the oil tank body 11. Since the outer surface of the driven shaft 31 is provided with a spiral groove 32, and the positioning ring 33 is slidably connected to the spiral groove 32 through a slider, the driven shaft 31 and the positioning ring 33 can be approximately regarded as a reciprocating screw. Therefore, as the driven shaft 31 rotates, the positioning ring 33 will reciprocate vertically on the surface of the driven shaft 31.

[0079] It should be noted that, in the above process, since the slide rod 34 is slidably connected inside the positioning ring 33, and scraper blades 35 are fixedly connected to both the upper and lower ends of the slide rod 34, the scraper blades 35 are symmetrically arranged with reference to the horizontal line of the positioning ring 33, and the scraper blades 35 are arranged in a circular array with reference to the center of the driven rotating shaft 31. Adjacent scraper blades 35 are slidably connected to each other. Therefore, the scraper blades 35 will move back and forth in the vertical direction inside the oil storage tank 11 with the positioning ring 33, cleaning the crystallized precipitate attached to the inner wall of the oil storage tank 11.

[0080] Furthermore, as the scraper 35 comes into contact with the crystalline material on the inner wall surface of the oil storage tank 11, when the scraper 35 comes into contact with a more stubborn crystal, the scraper 35 will be subjected to the squeezing force from the crystal, thereby producing an upward or downward movement (refer to the movement state of the positioning ring 33; when the positioning ring 33 moves downward, the scraper 35 is squeezed and moves upward, and vice versa). During the movement of the scraper 35, the connecting spring 36 set between the scraper 35 and the positioning ring 33 will be compressed.

[0081] Chicken fat contains abundant saturated fatty acids, such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and arachidic acid. These saturated fatty acids have relatively low solubility at room temperature. When chicken fat is exposed to low temperatures or large temperature fluctuations for a long time, the solubility of saturated fatty acids will further decrease, causing them to gradually precipitate from the oil and form crystals.

[0082] Through the arrangement of the scraper 35 and the connecting spring 36, when cleaning crystals precipitated on the inner wall of the oil storage tank 11, the scraper 35 will be displaced upward or downward due to the pressure of the crystals with strong adhesion. When the scraper 35 is displaced by pressure, its range of action is no longer limited to a fixed plane or trajectory. The upward or downward displacement allows the scraper 35 to better conform to the curved and irregular parts of the inner wall of the tank, ensuring that all parts of the inner wall can be effectively cleaned. In addition, the adhesion of crystals on the inner wall of the tank may vary. Some crystals have strong adhesion, and ordinary scraper 35 movement may not be able to completely remove them. When the scraper 35 is displaced by greater pressure, it can apply greater pressure to the crystals, thereby overcoming the strong adhesion and cleaning the stubborn crystals off the inner wall of the tank.

[0083] As the driven shaft 31 rotates, the extrusion wedge 41 fixedly connected to the bottom end of the driven shaft 31 will rotate accordingly. Since the bottom surface of the extrusion wedge 41 is set as an inclined plane and the top surface of the driven wedge 42 is set as an inclined plane that fits against the bottom surface of the extrusion wedge 41, as the extrusion wedge 41 rotates, the driven wedge 42 will be driven by the inclined plane of the extrusion wedge 41 to drive the extrusion member 43 fixedly connected to the bottom end of the driven wedge 42 to reciprocate vertically inside the limiting ring 44. During the reciprocating motion of the extrusion member 43, the telescopic spring 45 set between the driven wedge 42 and the limiting ring 44 will be compressed. After the inclined plane of the extrusion wedge 41 contacts the inclined plane of the driven wedge 42, it will return to the initial state under the elastic rebound force of the telescopic spring 45, so that the extrusion member 43 will reciprocate vertically inside the oil outlet 15.

[0084] It should be noted that after chicken fat is stored in storage tank 11 for a long time, the chicken fat, which is rich in saturated fatty acids, becomes more precipitated from the oil at lower temperatures due to the slower molecular motion of these fatty acids, making them more likely to arrange into an ordered crystal structure. Over time, the number of precipitated crystals gradually increases, leading to an increase in the overall viscosity of the chicken fat, resulting in a thickening phenomenon.

[0085] Therefore, when thickened chicken fat flows out through the oil outlet 15, it will accumulate inside the outlet 15, affecting the flow of chicken fat. The reciprocating extruder 43 can clear the blockage in the oil outlet 15, preventing the thickened chicken fat from accumulating and affecting the flow. Smooth oil flow is crucial during storage and use. When the oil outlet 15 is blocked by thickened chicken fat, the flow of oil will be uneven, sometimes fast and sometimes slow, and may even stop completely. The reciprocating motion of the extruder 43 can clear the blockage in time, ensuring that the oil flows out at a stable rate.

[0086] Chicken fat reabsorption:

[0087] After chicken fat has been stored in the oil storage tank 11 for a period of time, it will separate into layers. At this time, the staff will fix one end of the oil pump 53 to the oil outlet 15, and then turn on the oil pump 53. The oil pump 53 will then draw out the chicken fat stored in the oil storage tank 11 through the oil outlet 15, the connecting pipe 51 and the return pipe 13 and then inject it back into the oil storage tank 11.

[0088] Since the rotating blade 54 is rotatably connected to the inside of the oil storage tank and is located directly below the return pipe 13, the chicken oil re-injected into the oil storage tank 11 through the return pipe 13 will first contact the surface of the rotating blade 54, collide with the rotating blade 54, and cause the rotating blade 54 to rotate. Subsequently, the chicken oil through the rotating blade 54 will contact the stirring blade 23 located below the rotating blade 54. Due to the inclined plane of the stirring blade 23, the stirring blade 23 will rotate under the action of the chicken oil. Since the stepper motor 21 is equipped with a mechanical clutch device, and when the device is in the disengaged state, the power transmission between the output shaft of the stepper motor 21 and other components is cut off. When the stepper motor 21 is not started, the mechanical clutch device will be in the disengaged state. At this time, the stirring blade 23 can rotate without being driven by the stepper motor 21. Therefore, the stirring blade 23 can drive other objects to move inside the oil storage tank 11 according to the above-mentioned movement process.

[0089] By using a reflux pipe and an oil pump 53, chicken fat stored inside the oil storage tank 11 can be extracted without air contact and then refluxed back into the tank. During long-term storage, chicken fat may separate due to density differences or other factors. The reflux operation ensures the chicken fat is thoroughly stirred and mixed within the storage tank, eliminating separation and making more efficient use of the tank's space. Furthermore, the uniformly distributed chicken fat facilitates subsequent extraction and use, improving production and operational efficiency.

[0090] By setting up the stirring blade 23 and the rotating blade 54, they will collide and come into contact with the chicken oil during the chicken oil reflux process. Some antioxidants, preservatives or other functional ingredients need to be added to the chicken oil. The stirring action and the collision between the chicken oil and the rotating blade 54 can accelerate the diffusion and distribution of these additives in the chicken oil, so that they are evenly dispersed in the entire oil body, thereby better exerting their effects.
