[0001] This invention relates to the field of fish oil processing technology, specifically to a concentration device for fish oil production and processing. Background Technology
[0002] The fish oil processing process involves passing the oil through an evaporator, a centrifugal mixing tank, and a purification filtration tank in sequence. The evaporator is used to evaporate and separate excess water from the fish oil raw material to achieve preliminary concentration. The centrifugal mixing tank centrifuges and stirs the pre-concentrated raw material to separate impurities. Finally, the purification filtration tank filters the raw material after removing impurities to remove residual impurities, thereby obtaining concentrated fish oil.
[0003] In existing fish oil production and processing concentration equipment, an agitator is added inside the evaporator to stir the raw materials. The agitator prevents the materials from coking and accelerates the evaporation of moisture. However, the efficiency of accelerating the evaporation and separation of moisture by agitator alone is not high. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a concentration apparatus for fish oil production and processing, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a concentration device for fish oil production and processing, comprising a heating tank, the heating tank having a cylindrical structure with rounded ends, a stirring motor fixed at one end of the heating tank, a stirring shaft fixed at the output end of the stirring motor, and the stirring shaft being used to stir the heated fish oil raw material inside the heating tank, the top of the heating tank having a feed inlet and an exhaust outlet in sequence, and the bottom of the heating tank being connected to a discharge pipe, the end of the discharge pipe being connected to a pump body, the pump body being used to transport the fish oil raw material after water evaporation and separation to a centrifugal stirring tank;
[0006] An attachment heating component is disposed inside a heating tank. The attachment heating component is used to attach a layer of raw material, rotate it, and utilize the heat from the space above the liquid level inside the heating tank to uniformly heat the attached raw material.
[0007] The upper part of the inner wall of the heating tank is provided with a cavity, and the scraping component is set inside the cavity. The scraping component works with the stirring shaft to scrape off the raw material layer attached to both sides of the heated component.
[0008] Furthermore, the attached heating assembly includes a first turntable and a second turntable rotatably connected to both ends inside the heating tank, and an internal toothed ring is fixed to the side of the first turntable.
[0009] Furthermore, the inner side of the internal gear ring is meshed with a transmission gear, and the bottom of the transmission gear is meshed with an output gear.
[0010] Furthermore, the output gear is sleeved and fixed on the surface of the stirring shaft, and the end of the stirring shaft is rotatably connected to the second turntable.
[0011] Furthermore, the first turntable has an attachment plate distributed in a ring shape on the side away from the internal tooth ring, and the attachment plate has an arc-shaped structure.
[0012] Furthermore, a wall scraper is provided between the attachment plates, and the wall scraper is attached to the inner wall of the heating tank.
[0013] Furthermore, the scraper and the attachment plate are connected to the stirring shaft via a first turntable, an internal gear ring, a transmission gear, and an output gear, and the first turntable and the stirring shaft rotate in opposite directions.
[0014] Furthermore, the scraping assembly includes a first torsion spring disposed inside the cavity, and a transmission trigger is connected to the surface of the first torsion spring.
[0015] Furthermore, the bottom end of the transmission trigger protrudes from the inner surface of the heating tank, and the transmission trigger is located on the outside of the blades of the stirring shaft.
[0016] Furthermore, a second torsion spring is provided at the top of the transmission trigger, and a scraper strip is connected to the surface of the second torsion spring.
[0017] This invention provides a concentration apparatus for fish oil production and processing, which has the following beneficial effects:
[0018] 1. This fish oil concentration device utilizes a rotating stirring shaft to accelerate water evaporation and separation, while simultaneously employing a gear set to cause the attachment plate and wall scraper to rotate in opposite directions. The wall scraper can scrape off the raw material retained in the area between the stirring shaft and the heating tank, preventing the raw material in this area from being overheated and coking, thus adhering to the inner wall of the heating tank. At the same time, the rotating attachment plate continuously attaches raw material to form a raw material layer. When the raw material layer reaches the upper space inside the heating tank, its thin layer can be quickly heated to rapidly separate water. This cycle of forming a thin raw material layer further accelerates the separation of water from the raw material. Furthermore, the opposing rotation of the single blade side of the stirring shaft and the attachment plate can scrape off the heated raw material layer on the inner surface of the attachment plate.
[0019] 2. In this fish oil production and processing concentration device, when the stirring shaft scrapes off the raw material layer attached to the inner side of the attachment plate, the rotation of the wall scraper is combined with the lever principle to make the downward rotating end of the scraper strip stick to the outer side of the rotating attachment plate, so as to scrape off the raw material layer on the outer side of the attachment plate. Thus, the wall scraper can scrape off the heated raw material layer on its surface in each cycle and attach a new raw material layer. Attached Figure Description

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0027] like Figures 1-5 As shown, the present invention provides a technical solution: a concentration device for fish oil production and processing, including a heating tank 1, the heating tank 1 having a cylindrical structure with rounded ends, a stirring motor 2 fixed at one end of the heating tank 1, a stirring shaft 3 fixed at the output end of the stirring motor 2, and the stirring shaft 3 being used to stir the fish oil raw material heated inside the heating tank 1, a feed inlet 4 and an exhaust outlet 5 being sequentially opened at the top of the heating tank 1, and a discharge pipe 6 connected to the bottom of the heating tank 1, a pump body 7 being connected to the end of the discharge pipe 6, and the pump body 7 being used to transport the fish oil raw material after water evaporation and separation to a centrifugal stirring tank;
[0028] The attachment heating component 8 is disposed inside the heating tank 1. The attachment heating component 8 is used to attach the raw material layer to rotate and utilize the heat of the space above the liquid level inside the heating tank 1 to make the attached raw material uniformly heated.
[0029] A cavity 9 is formed in the upper part of the inner wall of the heating tank 1. A scraping assembly 10 is disposed inside the cavity 9. The scraping assembly 10 works with the stirring shaft 3 to scrape off the raw material layer attached to both sides of the heating assembly 8. The heating assembly 8 includes a first turntable 801 and a second turntable 802 rotatably connected to both ends inside the heating tank 1. An internal gear ring 803 is fixed to the side of the first turntable 801. A transmission gear 804 is meshed with the inner side of the internal gear ring 803. An output gear 805 is meshed with the bottom of the transmission gear 804. The output gear 805 is sleeved and fixed to the stirring shaft 3. The surface of the stirring shaft 3 is rotatably connected to the second turntable 802. The first turntable 801 has an attachment plate 806 distributed in a ring shape on the side away from the inner tooth ring 803. The attachment plate 806 has an arc-shaped structure. A wall scraper 807 is arranged between the attachment plates 806 and is attached to the inner wall of the heating tank 1. The wall scraper 807 and the attachment plate 806 are connected to the stirring shaft 3 through the first turntable 801, the inner tooth ring 803, the transmission gear 804, and the output gear 805. The first turntable 801 and the stirring shaft 3 rotate in opposite directions.
[0030] The specific operation is as follows: the fish oil raw material enters the heating tank 1 through the feed port 4. The heating tank 1 heats the fish oil raw material to evaporate the water contained inside. The water is discharged from the exhaust port 5. At the same time, the stirring motor 2 drives the stirring shaft 3 to stir the fish oil raw material to accelerate the release of water.
[0031] While the stirring shaft 3 rotates, the output gear 805 rotates accordingly and drives the first turntable 801 to rotate through the transmission gear 804 and the internal gear ring 803. The first turntable 801 carries the attachment plate 806 and the wall scraper 807, causing the second turntable 802 to rotate synchronously. At this time, the rotation direction of the first turntable 801 is opposite to the rotation direction of the stirring shaft 3.
[0032] When the attachment plate 806 rotates with the first turntable 801, it first descends from one side and is submerged below the raw material liquid level. Under the action of rotation, it rotates from the other side to the liquid level. At this time, a layer of raw material is attached to both the inner and outer sides of the attachment plate 806. During the rotation, the space and heat above the liquid level inside the heating tank 1 are used to quickly and evenly heat the attached thin layer of raw material, so that the water in the thin layer of raw material is quickly evaporated and escaped. As the attachment plate 806 rotates in a cycle, a thin layer of raw material is continuously attached, which is quickly heated and evaporated to separate the water for preliminary concentration. Since the attachment plate 806 is arc-shaped and rotates in the opposite direction to the stirring shaft 3, the side of the single blade of the stirring shaft 3 can scrape off the heated raw material layer on the inner side of the attachment plate 806 when it rotates.
[0033] Meanwhile, the wall scraper 807 rotates against the inner wall of the heating tank 1, which can scrape off the raw material on the inner wall of the heating tank 1 that has increased in viscosity due to heating above the liquid level, thus preventing the raw material from being overheated and coking.
[0034] After the water evaporates and is separated, the raw material enters the discharge pipe 6, and the pre-concentrated raw material is sent to the centrifugal mixing tank through the pump body 7 to remove impurities from the raw material.
[0035] Based on the above description, the present invention utilizes the rotation of the stirring shaft 3 to accelerate the evaporation and separation of water, while using a gear set to make the attachment plate 806 and the wall scraper 807 rotate in opposite directions. The wall scraper 807 can scrape off the raw material retained in the area between the stirring shaft 3 and the heating tank 1, so as to prevent the raw material in this area from being overheated and coking and adhering to the inner wall of the heating tank 1. At the same time, the rotating attachment plate 806 can continuously attach raw material to form a raw material layer. When the raw material layer reaches the upper space inside the heating tank 1, it can quickly separate water by utilizing its thin layer and rapid heating characteristics. Thus, the thin raw material layer is formed in this cycle, which can further accelerate the separation of water in the raw material. Furthermore, the opposing rotation of the single blade side of the stirring shaft 3 and the attachment plate 806 can scrape off the heated raw material layer on the inner side of the attachment plate 806.
[0036] like Figures 1-5 As shown, the scraping assembly 10 includes a first torsion spring 1001 disposed inside the cavity 9, and a transmission trigger 1002 is connected to the surface of the first torsion spring 1001. The bottom end of the transmission trigger 1002 protrudes from the inner surface of the heating tank 1, and the transmission trigger 1002 is located on the outer side of the blades of the stirring shaft 3. A second torsion spring 1003 is disposed at the top end of the transmission trigger 1002, and a scraper strip 1004 is connected to the surface of the second torsion spring 1003.
[0037] The specific operation is as follows: During the opposing rotation of the attachment plate 806 and the stirring shaft 3, the material layer on the inner side of the attachment plate 806 can be scraped off to prevent the material layer from adhering to the surface of the attachment plate 806 and being overheated. As for the material layer on the outer side of the attachment plate 806, when the material layer needs to be scraped off, since the scraping component 807 is always located in front of the attachment plate 806 in the direction of rotation, the scraping component 807 preferentially contacts the transmission trigger 1002 during rotation. At this time, the transmission trigger 1002 is subjected to force with the first torsion spring 1001 as the center. The core rotates upwards into the cavity 9, while the top of the transmission trigger 1002 carries the scraper strip 1004 downwards, so that the end of the scraper strip 1004 is attached to the outer surface of the attachment plate 806. Under the rotation of the attachment plate 806 and the elastic pressure given by the second torsion spring 1003, the downward-rotating end of the scraper strip 1004 is attached to the outer side of the rotating attachment plate 806 to scrape off the material layer on the outer side of the attachment plate 806, so that new material can be attached when the attachment plate 806 is submerged below the material liquid level.
[0038] After the scraper 807 rotates downward away from the transmission trigger 1002, the first torsion spring 1001 releases its stored force, causing the bottom end of the transmission trigger 1002 to rotate downward and protrude, while the scraper strip 1004 rotates upward back into the cavity 9, and waits for the next attachment plate 806 and scraper 807 to rotate and approach.
[0039] Based on the above description, when the stirring shaft 3 scrapes off the raw material layer attached to the inner side of the attachment plate 806, the present invention utilizes the rotational lever principle of the scraper 807 to make the downward-spinning end of the scraper strip 1004 adhere to the outer side of the rotating attachment plate 806, so as to scrape off the raw material layer on the outer side of the attachment plate 806. Thus, the scraper 807 can scrape off the heated raw material layer on its surface in each cycle and attach a new raw material layer.
[0040] In summary, when using this fish oil production and processing concentration device, the fish oil raw material first enters the heating tank 1 through the feed inlet 4. The heating tank 1 heats the fish oil raw material to evaporate the water contained inside. The water is discharged from the exhaust port 5. At the same time, the stirring motor 2 drives the stirring shaft 3 to stir the fish oil raw material to accelerate the evaporation of water.
[0041] While the stirring shaft 3 rotates, the output gear 805 rotates accordingly and drives the first turntable 801 to rotate through the transmission gear 804 and the internal gear ring 803. The first turntable 801 carries the attachment plate 806 and the wall scraper 807, causing the second turntable 802 to rotate synchronously. At this time, the rotation direction of the first turntable 801 is opposite to the rotation direction of the stirring shaft 3.
[0042] When the attachment plate 806 rotates with the first turntable 801, it first descends from one side and is submerged below the raw material liquid level. Under the action of rotation, it rotates from the other side to the liquid level. At this time, a layer of raw material is attached to both the inner and outer sides of the attachment plate 806. During the rotation, the space and heat above the liquid level inside the heating tank 1 are used to quickly and evenly heat the attached thin layer of raw material, so that the water in the thin layer of raw material is quickly evaporated and escaped. As the attachment plate 806 rotates in a cycle, a thin layer of raw material is continuously attached, which is quickly heated and evaporated to separate the water for preliminary concentration. Since the attachment plate 806 is arc-shaped and rotates in the opposite direction to the stirring shaft 3, the side of the single blade of the stirring shaft 3 can scrape off the heated raw material layer on the inner side of the attachment plate 806 when it rotates.
[0043] Meanwhile, the wall scraper 807 rotates against the inner wall of the heating tank 1, which can scrape off the raw material on the inner wall of the heating tank 1 that has increased in viscosity due to heating above the liquid level, thus preventing the raw material from being overheated and coking.
[0044] During the opposing rotation of the attachment plate 806 and the stirring shaft 3, the material layer on the inner side of the attachment plate 806 can be scraped off to prevent the material layer from adhering to the surface of the attachment plate 806 and being overheated. For the material layer on the outer side of the attachment plate 806, when this material layer needs to be scraped off, because the scraper 807 is always located in front of the attachment plate 806 in the direction of rotation, the scraper 807 preferentially contacts the transmission trigger 1002 during rotation. At this time, the transmission trigger 1002 is subjected to force and rotates around the first torsion spring 1001. The scraper 1004, carried by the top of the transmission trigger 1002, rotates downwards, so that the end of the scraper 1004 is attached to the outer surface of the attachment plate 806. Under the rotation of the attachment plate 806 and the elastic pressure given by the second torsion spring 1003, the downward rotating end of the scraper 1004 is attached to the outer side of the rotating attachment plate 806 to scrape off the material layer on the outer side of the attachment plate 806, so that new material can be attached when the attachment plate 806 is submerged below the material liquid level.
[0045] After the scraper 807 rotates downward away from the transmission trigger 1002, the first torsion spring 1001 releases its stored force, causing the bottom end of the transmission trigger 1002 to rotate downward and protrude, while the scraper strip 1004 rotates upward back into the cavity 9, and waits for the next attachment plate 806 and scraper 807 to rotate and approach.
[0046] After the water evaporates and is separated, the raw material enters the discharge pipe 6, and the pre-concentrated raw material is sent to the centrifugal mixing tank through the pump body 7 to remove impurities from the raw material.
