Description

Technical Field

[0001] The present invention relates to the technical field of oil storage tanks, and specifically to an oil storage tank for chicken oil. Background Art

[0002] An oil storage tank, abbreviated as an oil tank or storage tank, is a large container with a relatively regular shape for storing oil products. Oil storage tanks mainly include crude oil storage tanks, fuel storage tanks, lubricating oil storage tanks, animal and vegetable oil storage tanks, etc.

[0003] In the prior art, when storing a large amount of chicken oil, it is necessary to store the processed chicken oil through an animal and vegetable oil storage tank. Chicken oil contains various substances, such as triglycerides, free fatty acids, phospholipids, and other trace components, etc. The densities of these substances are different. Generally speaking, the density of triglycerides is relatively small, while the density of some impurities, moisture, and free fatty acids is relatively large. Under the action of gravity, substances with different densities will gradually stratify. Substances with a small density will float, and substances with a large density will sink. After standing for a long time, the chicken oil will stratify. The upper layer of the chicken oil is a relatively pure oil layer, while the lower layer will accumulate some impurities and moisture with a large density. In addition, at high temperatures, some components originally dissolved in the oil will precipitate as the temperature decreases, resulting in stratification.

[0004] Due to the different densities and compositions of each layer of the stratified chicken oil, a larger storage container may be required to accommodate it. This not only increases the storage cost but also occupies more storage space. In addition, stratification will cause chemical changes in the chicken oil. Impurities or moisture in the lower layer will cause the growth of microorganisms, producing rancid or other strange smells. In addition, substances such as aldehydes and ketones produced by oxidation reactions also have special smells, which will affect the original fragrance of the chicken oil.

[0005] In view of this, we propose an oil storage tank for chicken oil 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 oil, which has the following beneficial effects:

[0024] Through the setting of the continuously rotating stirring paddle blade, the stirring paddle blade rotates in the oil storage tank body to stir the chicken oil stored in the oil storage tank body. The rotation of the stirring paddle blade can fully mix the chicken oil in different parts of the oil storage tank. The rotation of the stirring paddle blade can fully mix the chicken oil in different parts of the oil storage tank. Continuous stirring can make the chicken oil fully contact with the air, accelerate the consumption and renewal of oxygen therein, and reduce the oxidation reaction caused by too high local oxygen concentration. In addition, the rotation of the stirring paddle blade can keep the chicken oil in a continuous motion state, reducing the residence time and adhesion opportunity of the chicken oil on the tank wall. In this way, it can prevent the formation of a thick deposition layer of chicken oil on the tank wall and reduce the risk of tank wall corrosion caused by long-term adhesion;

[0025] In addition, the stirring paddle blade will perform continuous vibration during rotation. The continuous vibration can break the local accumulation or agglomeration phenomenon formed by the chicken oil during the stirring process. When the stirring paddle blade is stationary or rotates relatively smoothly, some components in the chicken oil will aggregate together due to intermolecular forces to form larger lumps. And the vibration can continuously disperse these lumps to ensure that all parts of the chicken oil are fully stirred and mixed. In addition, the continuous vibration can make the flow of the chicken oil in the oil storage tank smoother. When the stirring paddle blade rotates, the vibration on its surface will produce a "micro-disturbance" effect, destroying the originally relatively stable flow structure of the chicken oil and making it form more eddies and turbulences. This change in the flow state can increase the contact area and relative movement speed between the chicken oil and the stirring paddle blade, thereby improving the stirring efficiency;

[0026] By setting the stirring blades and small stirring paddles with different rotation speeds and opposite rotation directions in the vertical direction, the stirring components with different rotation speeds and directions can form complex and diverse flow patterns in the storage oil tank. The small stirring paddle with a faster rotation speed can generate a larger centrifugal force, throwing the chicken oil from the center to the surrounding, enabling the chicken oil to quickly spread throughout the tank space; while the stirring blades with a slower rotation speed and opposite rotation direction can push the chicken oil inward during the outward diffusion process, thus avoiding the phenomenon of local accumulation or precipitation of chicken oil in the storage oil tank. In addition, when the stirring components in two different motion states act simultaneously, a relative velocity difference and shear force will be formed between them, and this shear force can decompose the macromolecular clusters in the chicken oil into smaller particles, making it more evenly dispersed in the chicken oil;

[0027] By setting the scraping blade and the connecting spring, when the scraping blade cleans the crystals precipitated on the inner wall of the storage oil tank, it will produce an upward or downward displacement under the extrusion of the crystals with a larger adhesion force. When the scraping blade produces a displacement under extrusion, its action range is no longer limited to a fixed plane or trajectory. The upward or downward displacement can make the scraping blade better fit the curved surface 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 a stronger adhesion force, and ordinary scraping blade movement may not be able to completely remove them. When the scraping blade produces a larger displacement under extrusion, it can apply a greater pressure on the crystals, thus overcoming the stronger adhesion force and cleaning the stubborn crystals from the inner wall of the tank;

[0028] By setting the reciprocating extrusion part, the oil outlet pipe can be dredged to avoid the thickened chicken oil accumulating at the oil outlet pipe, which affects the outflow of chicken oil. During the storage and use of oil, the smoothness of oil outflow is crucial. When the oil outlet pipe is blocked by thickened chicken oil, the outflow of oil will be uneven, sometimes fast and sometimes slow, and may even stop completely. However, through the reciprocating movement of the extrusion part, the pipe orifice can be dredged in time to ensure that the oil can flow out at a stable speed;

[0029] By setting the reflux pipeline and the oil pump, the chicken oil stored inside the storage oil tank can be pumped out and then refluxed into the storage oil tank without air contact. During long-term storage, the chicken oil may stratify due to density differences or other factors. Through the reflux operation, the chicken oil can be fully stirred and mixed in the storage oil tank, eliminating the stratification phenomenon and making more effective use of the space of the storage oil tank. At the same time, the evenly distributed chicken oil is also convenient for subsequent extraction and use, improving the production and operation efficiency;

[0030] Through the settings of the stirring paddle and the rotating paddle, during the backflow process of chicken fat, it will collide and contact with the chicken fat. Some antioxidants, preservatives or other functional components need to be added to the chicken fat. The function of stirring and the collision between the chicken fat and the rotating paddle can accelerate the diffusion and distribution of these additives in the chicken fat, making them evenly dispersed in the entire oil body, so as to better play their roles.

[0061] Further embodiments

[0062] Please refer to Figure 1 、 Figure 2 and Figure 7 For the oil storage tank for chicken oil, it further includes a reflux assembly disposed below the outlet pipe orifice 15;

[0063] The reflux assembly includes a connecting pipe 51 fixedly connected to the reflux pipe orifice 13. A support block 52 is fixedly connected to the outer surface of the connecting pipe 51. A fuel pump 53 is fixedly connected to one end of the connecting pipe 51 far from the reflux pipe orifice 13. A rotating paddle 54 is rotatably connected to the inner wall of the top end of the oil storage tank body 11.

[0064] Among them, one end of the support block 52 far from the connecting pipe 51 is fixedly connected to the outer wall of the oil storage tank body 11. One end of the fuel pump 53 far from the connecting pipe 51 is detachably and fixedly installed at the bottom end of the outlet pipe orifice 15. The rotating paddle 54 is disposed above the stirring paddle 23.

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

[0066] Storage of chicken oil:

[0067] The staff first fixedly installs the chicken oil to be stored after treatment via a pipeline with the inlet pipe orifice 14, and then injects it into the interior of the oil storage tank body 11 through the inlet pipe orifice 14. After the injection is completed, the pipeline is detached from the inlet pipe orifice 14 to make the two separate from each other. Subsequently, the inlet pipe orifice 14 is sealed, and the storage of chicken oil is completed.

[0068] Stirring of chicken oil:

[0069] The chicken oil itself contains a certain amount of moisture. After standing for a long time, the moisture will gradually sink to the bottom, forming an obvious oil-water stratification phenomenon. The upper layer is the oil part, generally light yellow or yellow, and the lower layer is a mixture of moisture and other impurities. Therefore, it is necessary to stir the chicken oil to avoid stratification during long-term storage.

[0070] At this time, the staff starts the stepping motor 21 through an external controller. Since the output shaft end of the stepping motor 21 is fixedly connected to one end of the driving rotating shaft 22 that penetrates outside the storage oil tank body 11, the start of the stepping motor 21 will cause the driving rotating shaft 22 to rotate inside the storage oil tank body 11. At this time, the stirring paddle 23 that is vertically slidably connected to the outer surface of the driving rotating shaft 22 will rotate accordingly, stirring the chicken oil stored in the storage oil tank body 11;

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

[0072] Through the setting of the continuously rotating stirring paddle 23, the stirring paddle 23 rotates in the storage oil tank body 11 to stir the chicken oil stored in the storage oil tank body 11. The rotation of the stirring paddle 23 can fully mix the chicken oil in different parts of the storage oil tank. The rotation of the stirring paddle 23 can fully mix the chicken oil in different parts of the storage oil tank. Continuous stirring can make the chicken oil fully contact with the air, accelerate the consumption and renewal of oxygen therein, and reduce the oxidation reaction caused by too high local oxygen concentration. In addition, the rotation of the stirring paddle 23 can keep the chicken oil in a continuous movement state, reduce the residence time and adhesion opportunity of the chicken oil on the tank wall, which can prevent the formation of a thick sediment layer on the tank wall and reduce the risk of tank wall corrosion caused by long-term adhesion;

[0073] In addition, when the stirring blade 23 rotates, it will vibrate continuously by itself. The continuous vibration can break the local accumulation or agglomeration phenomenon formed by chicken fat during the stirring process. When the stirring blade 23 is stationary or rotates relatively smoothly, some components in the chicken fat will aggregate together due to intermolecular forces to form larger lumps. The vibration can disperse these lumps continuously, ensuring that all parts of the chicken fat can be fully stirred and mixed. In addition, the continuous vibration can make the flow of chicken fat in the storage tank smoother. When the stirring blade 23 rotates, the vibration on its surface will generate a "micro-perturbation" effect, destroying the relatively stable flow structure of the chicken fat and making it form more eddies and turbulences. This change in the flow state can increase the contact area and relative movement speed between the chicken fat and the stirring blade 23, thereby improving the stirring efficiency.

[0074] As the driving rotating shaft 22 rotates, since the driven gear 2707 is fixedly connected to the bottom end of the driving rotating shaft 22, the driven gear 2707 fixedly connected to the bottom end of the driving rotating shaft 22 will rotate synchronously, and through the meshing gear 2706 arranged between the rotating gear 2704 and the driven gear 2707 and meshing with both of them, it will cause the rotating gear 2704 to rotate on the outer surface of the driving rotating shaft 22. At this time, the limiting sleeve 2701 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 that of the rotating gear 2704, and the driven gear 2707 is connected to the rotating gear 2704 through the meshing gear 2706, 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] In addition, due to the meshing arrangement of the rotating gear 2704, the meshing gear 2706, and the driven gear 2707, when the driving rotating shaft 22 drives the stirring blade 23 and the driven gear 2707 to rotate in the clockwise direction, the rotating gear 2704 and the small stirring paddle 2703 will rotate in the counterclockwise direction under the driving action of the meshing gear 2706, and the rotation speed of the small stirring paddle 2703 is greater than that of the stirring blade 23;

[0077] By vertically arranging the stirring paddles 23 with different rotation speeds and opposite rotation directions and the small stirring paddles 2703, the stirring components with different rotation speeds and directions can form complex and diverse flow patterns in the storage oil tank. The small stirring paddles 2703 with a faster rotation speed can generate a greater centrifugal force, throwing the chicken oil from the center to the surroundings, enabling the chicken oil to quickly spread throughout the tank space; while the stirring paddles 23 with a slower rotation speed and opposite rotation direction can push the chicken oil inward during the outward diffusion process, thus avoiding the phenomenon of local accumulation or precipitation of chicken oil in the storage oil tank body 11. In addition, when the two stirring components with different motion states act simultaneously, a relative speed difference and shear force will be formed between them, and this shear force can decompose the macromolecular clusters in the chicken oil into smaller particles, making it more evenly dispersed in the chicken oil.

[0078] With the fixed connection of the driven gear 2707 and the driven rotating shaft 31, the driven rotating shaft 31 will rotate inside the storage oil tank body 11 accordingly. Since spiral grooves 32 are provided on the outer surface of the driven rotating shaft 31, and the positioning ring 33 is slidably connected to the inside of the spiral grooves 32 through sliders, at this time, the driven rotating shaft 31 and the positioning ring 33 can be approximately regarded as a reciprocating lead screw. Therefore, with the rotation of the driven rotating shaft 31, the positioning ring 33 will perform a reciprocating motion in the vertical direction on the surface of the driven rotating shaft 31;

[0079] It should be noted that in the above process, since the slide bar 34 is slidably connected through the inside of the positioning ring 33, and scraping blades 35 are fixedly connected to both the upper and lower ends of the slide bar 34. The scraping blades 35 are symmetrically arranged with reference to the horizontal line of the positioning ring 33, and the scraping blades 35 are arranged in a circumferential array with reference to the center of the driven rotating shaft 31. The adjacent scraping blades 35 are slidably connected to each other. Therefore, the scraping blades 35 will perform a reciprocating motion in the vertical direction inside the storage oil tank body 11 along with the positioning ring 33 to clean the crystal precipitates attached to the inner wall of the storage oil tank body 11;

[0080] And with the contact of the scraping blades 35 with the crystal substances on the inner wall surface of the storage oil tank body 11, when the scraping blades 35 contact the relatively stubborn crystals, the scraping blades 35 will be subjected to the extrusion force from the crystals, and then move upward or downward (specifically referring to the motion state of the positioning ring 33. When the positioning ring 33 moves downward, the scraping blades 35 are squeezed and move upward, and vice versa). During the movement of the scraping blades 35, the connecting springs 36 arranged between the scraping blades 35 and the positioning ring 33 will be compressed;

[0081] Chicken oil contains rich saturated fatty acids, such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, etc. The solubility of these saturated fatty acids is relatively low at normal temperature. When chicken oil is in a low-temperature environment for a long time or under conditions of large temperature fluctuations, the solubility of saturated fatty acids will further decrease, resulting in their gradual precipitation from the oil to form crystals;

[0082] With the arrangement of the scraping blade 35 and the connecting spring 36, when the scraping blade 35 cleans the crystals precipitated on the inner wall of the storage oil tank body 11, it will generate upward or downward displacement under the extrusion of crystals with greater adhesion force. When the scraping blade 35 generates displacement under extrusion, its action range is no longer limited to a fixed plane or trajectory. The upward or downward displacement can make the scraping blade 35 better fit the curved surface and irregular parts of the inner wall of the tank, ensuring that all parts on 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 stronger adhesion force, and the movement of the ordinary scraping blade 35 may not be able to completely remove them. When the scraping blade 35 generates a large displacement under extrusion, it can apply a greater pressure on the crystals, thereby overcoming the stronger adhesion force and cleaning the stubborn crystals from the inner wall of the tank.

[0083] As the driven rotating shaft 31 rotates, the extrusion wedge block 41 fixedly connected to the bottom end of the driven rotating shaft 31 will rotate accordingly. And because the bottom surface of the extrusion wedge block 41 is set as an inclined plane, and the top surface of the driven wedge block 42 is set as an inclined plane that fits the bottom surface of the extrusion wedge block 41, therefore, as the extrusion wedge block 41 rotates, the driven wedge block 42 will drive the extrusion member 43 fixedly connected to the bottom end of the driven wedge block 42 to perform a reciprocating vertical movement inside the limiting ring 44 under the action of the inclined plane of the extrusion wedge block 41. During the reciprocating movement of the extrusion member 43, the telescopic spring 45 arranged between the driven wedge block 42 and the limiting ring 44 will be compressed, and after the inclined plane of the extrusion wedge block 41 contacts the inclined plane of the driven wedge block 42, it will return to the initial state under the elastic restoring force of the telescopic spring 45, enabling the extrusion member 43 to perform a reciprocating vertical movement inside the oil outlet 15;

[0084] It should be noted that after the chicken oil in the storage oil tank body 11 is stored for a long time, the chicken oil is rich in saturated fatty acids. At a relatively low temperature, the molecular movement of these saturated fatty acids slows down, making it easier for them to arrange into an ordered crystal structure and thus precipitate from the oil. As time goes by, the precipitated crystals gradually increase, resulting in an increase in the overall viscosity of the chicken oil, showing a phenomenon of thickening;

[0085] Therefore, the thickened chicken oil will accumulate inside the oil outlet 15 when flowing out through the oil outlet 15, affecting the outflow of the chicken oil. By arranging the reciprocating extrusion member 43, the oil outlet 15 can be dredged to prevent the thickened chicken oil from accumulating at the oil outlet 15 and affecting the outflow of the chicken oil. During the storage and use of the oil, the smoothness of the oil outflow is crucial. When the oil outlet 15 is blocked by the thickened chicken oil, the outflow of the oil will be uneven, sometimes fast and sometimes slow, and may even stop completely. However, through the reciprocating movement of the extrusion member 43, the pipe orifice can be dredged in time to ensure that the oil can flow out at a stable speed.

[0086] Backflow of chicken oil:

[0087] After the chicken oil has been stored in the storage tank body 11 for a period of time, stratification will occur. At this time, one end of the oil pump 53 is fixedly installed with the oil outlet 15. Subsequently, the oil pump 53 is turned on, and the chicken oil stored in the storage tank body 11 is pumped out through the oil outlet 15, the connecting pipe 51 and the return pipe orifice 13, and then injected back into the storage tank body 11;

[0088] Since the rotating blade 54 is rotatably connected inside the storage tank and the rotating blade 54 is located directly below the return pipe orifice 13, the chicken oil re-injected into the storage tank body 11 through the return pipe orifice 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 passing through the rotating blade 54 will contact the stirring blade 23 provided below the rotating blade 54. Due to the setting of the inclined plane of the stirring blade 23, the stirring blade 23 will rotate under the action of the chicken oil. Since the stepping motor 21 is equipped with a mechanical clutch device and the power transmission between the output shaft of the stepping motor 21 and other components is cut off when the device is in the disengaged state. When the stepping 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 stepping motor 21. Therefore, the stirring blade 23 can drive other objects to move inside the storage tank body 11 according to the above movement process;

[0089] Through the setting of the return pipeline and the oil pump 53, the chicken oil stored inside the storage tank body 11 can be pumped out and then refluxed into the storage tank body 11 without air contact. During long-term storage, the chicken oil may stratify due to density differences or other factors. Through the reflux operation, the chicken oil can be fully stirred and mixed in the storage tank, eliminating the stratification phenomenon and making more effective use of the space of the storage tank. At the same time, the evenly distributed chicken oil is also convenient for subsequent extraction and use, improving the production and operation efficiency.

[0090] Through the setting of the stirring blade 23 and the rotating blade 54, during the reflux process of the chicken oil, it will collide and contact with the chicken oil. Some antioxidants, preservatives or other functional components need to be added to the chicken oil. The stirring effect and the collision of the chicken oil with the rotating blade 54 can accelerate the diffusion and distribution of these additives in the chicken oil, making them evenly dispersed in the entire oil body, so as to better play their roles.
