Description

Technical Field

[0001] The invention relates to the technical field of fish oil processing, in particular to a concentrating device for fish oil production and processing. Background Art

[0002] During the fish oil processing process, it needs to pass through an evaporation tank, a centrifugal stirring tank and a purification filter tank in sequence. The evaporation tank is used to evaporate and separate excess water in the fish oil raw material to achieve preliminary concentration. The centrifugal stirring tank centrifugally stirs the raw material after preliminary concentration to separate impurities. The raw material after impurities are then filtered through a purification filter tank to remove residual impurities, thereby obtaining concentrated fish oil.

[0003] In existing fish oil production and processing concentration devices, stirring paddles are added inside the evaporation tank to stir the raw materials. The stirring paddles stir the raw materials to prevent coking and accelerate water escape. However, the efficiency of accelerating water evaporation and separation by only using stirring paddles is not high. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a concentrating device for fish oil production and processing, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a concentrating device for fish oil production and processing, comprising a heating tank, the heating tank having a circular tubular structure with rounded ends at both 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 is used to stir the heated fish oil raw material in the heating tank; a feed inlet and an exhaust port are sequentially formed at the top of the heating tank, and a discharge pipe is connected to the bottom of the heating tank, the end of the discharge pipe is connected to a pump body, and the pump body is used to transport the fish oil raw material after water evaporation and separation to a centrifugal stirring tank; The attached heating component is arranged inside the heating tank, and is used to rotate the attached raw material layer and utilize the heat of the space above the liquid level inside the heating tank to uniformly heat the attached raw materials; A concave cavity is provided on the upper portion of the inner wall of the heating tank, and a scraping assembly is arranged inside the concave cavity. The scraping assembly cooperates with the stirring shaft to scrape off the raw material layers adhered to both sides of the heated assembly.

[0006] Furthermore, the attached heated component includes a first turntable and a second turntable rotatably connected to the two ends of the interior of the heating tank, and an inner gear ring is fixed to the side of the first turntable.

[0007] Furthermore, the inner side surface of the inner gear ring is meshedly connected with a transmission gear, and the bottom of the transmission gear is meshedly connected with an output gear.

[0008] Further, the output gear sleeve is fixed on the surface of the stirring shaft, and the end of the stirring shaft is rotationally connected with the second rotating disc.

[0009] Further, the first rotating disc is provided with the attachment plates in an annular shape on the side surface away from the inner gear ring.

[0010] Further, the scraper is arranged between the attachment plates and is attached to the inner wall of the heating tank.

[0011] Further, the scraper, the attachment plates, the first rotating disc, the inner gear ring, the transmission gear and the output gear are transmissionally connected with the stirring shaft, and the first rotating disc rotates towards the stirring shaft.

[0012] Further, the scraping assembly comprises a first torsion spring arranged inside the cavity, and the surface of the first torsion spring is connected with a transmission trigger.

[0013] Further, the bottom end of the transmission trigger protrudes from the inner surface of the heating tank, and the transmission trigger is located on the outer side of the blade of the stirring shaft.

[0015] The fish oil production and processing concentration device has the following beneficial effects: 1. The fish oil production and processing concentration device utilizes the rotation of the stirring shaft to accelerate the evaporation and separation of water, and utilizes the gear set to make the attachment plates and the scraper rotate towards each other. The scraper can scrape off the raw materials remaining in the area between the stirring shaft and the heating tank, so as to prevent the raw materials in the area from being overheated and coking and adhering to the inner wall of the heating tank. Meanwhile, the attachment plates in the circulating rotation can continuously adhere to the raw materials to form a raw material layer. When the raw material layer is selected to the upper space inside the heating tank, the thin layer can be quickly heated to quickly separate the water, so that the thin raw material layer is formed in circulation, thereby further accelerating the separation of water in the raw materials. The rotation of the single-blade side of the stirring shaft and the attachment plates can scrape off the raw material layer on the inner side of the attachment plates.

[0016] 2. The fish oil production and processing concentration device utilizes the rotation of the scraper to cooperate with the lever principle to make the lower end of the scraper strip adhere 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 scraper can scrape off the raw material layer on the surface after being heated and adhere to the new raw material layer in each cycle. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0019] The embodiments of the application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the application, but cannot be used to limit the scope of the application.

[0020] As Figures 1-5 shown, the application provides a technical scheme: a concentration device for fish oil production and processing, comprising a heating tank 1, the heating tank 1 is in a circular tube structure and the two ends are round, one end of the heating tank 1 is fixed with a stirring motor 2, the output end of the stirring motor 2 is fixed with a stirring shaft 3, and the stirring shaft 3 is used for stirring the heated fish oil raw material in the heating tank 1, the top of the heating tank 1 is sequentially provided with a feed inlet 4 and an exhaust port 5, and the bottom of the heating tank 1 is connected with a discharge pipe 6, the end of the discharge pipe 6 is connected with a pump body 7, and the pump body 7 is used for conveying the fish oil raw material after water evaporation and separation to a centrifugal stirring tank; An attached heating assembly 8 is arranged in the heating tank 1, the attached heating assembly 8 is used for attaching the raw material layer to rotate and using the space heat above the liquid level in the heating tank 1 to make the attached raw material uniformly heated; A concave cavity 9 is formed in the upper part of the inner wall of the heating tank 1, and a scraping assembly 10 is arranged in the concave cavity 9. The scraping assembly 10 cooperates with the stirring shaft 3 to scrape off the raw material layer adhered to the two surfaces of the heated assembly 8. The heated assembly 8 comprises a first rotating disc 801 and a second rotating disc 802 rotatably connected to the two ends inside the heating tank 1. The side surface of the first rotating disc 801 is fixed with an inner tooth ring 803. The inner side surface of the inner tooth ring 803 is engaged with a transmission gear 804. The bottom of the transmission gear 804 is engaged with an output gear 805. The output gear 805 is fixedly sleeved on the surface of the stirring shaft 3. The end of the stirring shaft 3 is rotatably connected with the second rotating disc 802. The side surface of the first rotating disc 801 away from the inner tooth ring 803 is annularly distributed with adhesion plates 806. The adhesion plates 806 are arc-shaped structures. The adhesion plates 806 are arranged with scraping wall pieces 807. The scraping wall pieces 807 are attached to the inner wall of the heating tank 1. The scraping wall pieces 807 and the adhesion plates 806 are drivingly connected with the stirring shaft 3 through the first rotating disc 801, the inner tooth ring 803, the transmission gear 804 and the output gear 805. The first rotating disc 801 rotates towards the stirring shaft 3. Specifically, the fish oil raw material enters the heating tank 1 through the feeding port 4. The heating tank 1 heats the fish oil raw material to evaporate the water contained therein. 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 escape of water. At the same time, the output gear 805 rotates and drives the first rotating disc 801 to rotate through the transmission gear 804 and the inner tooth ring 803. The first rotating disc 801 carries the adhesion plates 806 and the scraping wall pieces 807 to make the second rotating disc 802 rotate synchronously. At this time, the rotating direction of the first rotating disc 801 is opposite to that of the stirring shaft 3. When the adhesion plates 806 rotate with the first rotating disc 801, they rotate downward from one side below the raw material level and rotate upward from the other side above the raw material level under the action of rotation. At this time, the inner and outer side surfaces of the adhesion plates 806 are both adhered with a layer of raw material. In the rotating process, the space above the liquid level in the heating tank 1 and the heat are used to quickly and uniformly heat the thin layer of raw material adhered, so that the water in the thin layer of raw material is quickly evaporated and separated. Thus, the thin layer of raw material is continuously adhered and generated by the circulating rotation of the adhesion plates 806, so that the water is quickly evaporated and separated to preliminarily concentrate the raw material. Since the adhesion plates 806 are arc-shaped and rotate towards the stirring shaft 3, the side surface of the single blade of the stirring shaft 3 can scrape off the heated raw material layer on the inner side surface of the adhesion plates 806 when the stirring shaft 3 rotates. At the same time, the scraping wall pieces 807 rotate and adhere to the inner wall of the heating tank 1, which can scrape off the raw material with increased viscosity on the inner wall of the heating tank 1 above the liquid level due to heating, so as to avoid excessive heating of the raw material and coking. The raw material after the water is evaporated and separated enters the discharge pipe 6, and the preliminarily concentrated raw material is sent into the centrifugal stirring tank through the pump body 7 to remove impurities in the raw material. Based on the above description, the present invention utilizes the rotation of the stirring shaft 3 to accelerate the evaporation and separation of water, and at the same time utilizes the gear set to make the attachment plate 806 and the scraper 807 rotate in opposite directions. The scraper 807 can scrape off the raw materials retained in the area between the stirring shaft 3 and the heating tank 1 to prevent the raw materials in this area from being overheated and coking and adhering to the inner wall of the heating tank 1. At the same time, the attachment plate 806 in circular rotation can continuously attach the raw materials to form a raw material layer. When the raw material layer is selected to the upper space inside the heating tank 1, its thin layer can be heated quickly to quickly separate the water, thereby forming a thin raw material layer in this cycle, which can further accelerate the separation of water in the raw material, and the heated raw material layer on the inner side of the attachment plate 806 can be scraped off by the opposite rotation of the single blade side of the stirring shaft 3 and the attachment plate 806.

[0021] like Figures 1-5 As shown, the scraper assembly 10 includes a first torsion spring 1001 disposed inside the concave 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 outside the blades of the stirring shaft 3. A second torsion spring 1003 is provided at the top of the transmission trigger 1002, and a scraper strip 1004 is connected to the surface of the second torsion spring 1003. The specific operation is as follows: the material layer on the inner side of the attachment plate 806 can be scraped off during the rotation of the attachment plate 806 and the stirring shaft 3 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, the scraper 807 is always located in front of the attachment plate 806 in the direction of rotation. The scraper 807 contacts the transmission trigger 1002 first during the rotation process. At this time, the transmission trigger 1002 is subjected to a force with the first torsion spring 1001 as a circle. The center of the rotary table 1000 rotates upward to the inside of the concave cavity 9, and the top end of the transmission trigger 1002 carries the scraper strip 1004 to rotate downward, 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 downwardly rotated end of the scraper strip 1004 is attached to the outer side of the rotating attachment plate 806 to scrape off the raw material layer on the outer side of the attachment plate 806, so that the attachment plate 806 can be attached with new raw material when it is rotated downward and submerged below the raw material liquid level. After the scraper 807 rotates downward and leaves the transmission trigger 1002, the first torsion spring 1001 releases the stored force, causing the bottom end of the transmission trigger 1002 to rotate downward and protrude, and the scraper strip 1004 rotates back to the inside of the cavity 9 and waits for the next attachment plate 806 and the scraper 807 to rotate closer. Based on the above description, when the stirring shaft 3 scrapes the material layer attached to the inner side of the attachment plate 806, the rotating scraping wall part 807 cooperates with the lever principle to make the lower end of the scraping plate 1004 adhere to the outer side of the rotating attachment plate 806, so as to scrape the material layer on the outer side of the attachment plate 806, thereby making the scraping wall part 807 scrape the material layer after being heated on its surface in each cycle and attach a new material layer.

[0022] In summary, the concentration device for fish oil production and processing is used. First, the fish oil raw material enters the inside of the heating tank 1 from the feed port 4. The heating tank 1 heats the fish oil raw material to evaporate the water contained in it. 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 escape of water. While the stirring shaft 3 rotates, the output gear 805 rotates and drives the first rotating disc 801 to rotate through the transmission gear 804 and the inner tooth ring 803. The first rotating disc 801 carries the attachment plate 806 and the scraping wall part 807 to make the second rotating disc 802 rotate synchronously. At this time, the rotating direction of the first rotating disc 801 is opposite to that of the stirring shaft 3. When the attachment plate 806 rotates with the first rotating disc 801, it rotates downward from one side below the material level and rotates upward from the other side above the material level under the action of rotation. At this time, the attachment plate 806 has a layer of material attached to the inner and outer sides. In the rotating process, the space above the liquid level in the heating tank 1 and the heat are used to quickly and uniformly heat the thin layer of material attached, so that the water in the thin layer of material is quickly evaporated and separated. Thus, the thin layer of material is continuously attached and heated to evaporate and separate water to preliminarily concentrate. Since the attachment plate 806 is arc-shaped and rotates towards the stirring shaft 3, the edge side of the single blade of the stirring shaft 3 can scrape the material layer on the inner side of the attachment plate 806 after being heated. At the same time, the scraping wall part 807 rotates against the inner wall of the heating tank 1, which can scrape the material with increased viscosity on the inner wall of the heating tank 1 above the liquid level due to heating, to avoid excessive heating of the material and coking. In the relative 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 to prevent the material layer from being attached to the surface of the attachment plate 806 and being heated, and for the material layer on the outer side of the attachment plate 806, when the material layer needs to be scraped, the scraping wall piece 807 is always located in front of the rotation direction of the attachment plate 806, and the scraping wall piece 807 is in contact with the transmission handle 1002 in the rotation process, at this time, the transmission handle 1002 is forced to rotate around the first torsional spring 1001 and rotates upward to the inside of the recessed cavity 9, and the top end of the transmission handle 1002 carries the scraping strip 1004 to rotate downward, so that the end of the scraping strip 1004 is attached to the outer surface of the attachment plate 806, and under the rotation of the attachment plate 806 and the elastic pressure given by the second torsional spring 1003, the end of the scraping strip 1004 is attached to the outer side of the rotating attachment plate 806, so as to scrape the material layer on the outer side of the attachment plate 806, so that the attachment plate 806 can attach new material when rotating downward into the material liquid level; After the scraping wall piece 807 rotates downward away from the transmission handle 1002, the first torsional spring 1001 releases the stored force to make the bottom end of the transmission handle 1002 rotate downward and protrude, and the scraping strip 1004 rotates back to the inside of the recessed cavity 9, and waits for the next rotation of the attachment plate 806 and the scraping wall piece 807 to approach. The material after water evaporation separation enters the discharge pipe 6, and the preliminary concentrated material is sent into the centrifugal stirring tank by the pump body 7 to remove impurities in the material.
