Description

Technical Field

[0001] The present application relates to the technical field of fish oil processing, and in particular to a fish oil transfer device in a sedimentation tank. Background Art

[0002] Fish oil is a general term for all oil substances in fish, including body oil, liver oil and brain oil. Main fish oil is a kind of oil extracted from fatty fish. It is rich in polyunsaturated fatty acids and has health benefits such as anti-inflammatory and blood lipid regulation. The raw materials for making fish oil preparations are commonly found in mackerel, herring, tuna, flounder, salmon, cod liver, whale fat, seal oil, etc. A small amount of vitamin E is generally added to play an antioxidant role. Since fish oil is relatively expensive, it must be stored more precisely to preserve good fish oil.

[0003] Existing fish oil storage devices are specially designed for fish oil transit and transportation. Their main function is to achieve safe and efficient transfer of fish oil during the fish oil processing process. A pump is connected to the oil outlet, which is the power source for fish oil transfer.

[0004] In the process of implementing this application, there are at least the following problems in the existing technology: although the oil outlet of the fish oil storage tank is provided with a solenoid valve, the oil outlet is not provided with an intermittent discharge function. The lack of the intermittent discharge function means that the flow rate of the oil outlet is continuous and difficult to accurately control. This may make it difficult to achieve accurate flow output when a small flow rate or a specific flow rate is required. Therefore, a sedimentation tank fish oil transfer device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a fish oil transfer device for a sedimentation tank, which has the advantages of strong practicality and easy unloading, and solves the problem of lack of intermittent unloading function at the oil outlet.

[0006] In summary, the present application provides the following technical solutions: a sedimentation tank fish oil transfer device, comprising a fish oil sedimentation tank, wherein the processing end of the fish oil sedimentation tank is fixedly connected to an intermittent feeding device;

[0007] The intermittent feeding equipment includes a housing and a quantitative rotor rotatably arranged inside the housing;

[0008] The lower surface of the housing is fixedly connected to a transfer device, which includes a pump housing, two valve housings fixedly connected to opposite sides of the pump housing, a piston block reciprocatingly arranged inside the pump housing, and a piston rod fixedly installed on the outer surface of the piston block and extending outside the pump housing, and a one-way valve plate is elastically hingedly installed in each of the two valve housings;

[0009] The fish oil sedimentation tank is provided with a driving device for driving the transfer device and the intermittent unloading device. The driving device includes a driving motor, a transmission gear, a driven gear, and a connecting rod. One end of the connecting rod is connected and fixed to the end of the piston rod, and the other end of the connecting rod is welded with a connecting ring. The outer surface of the driven gear is fixedly mounted with a shaft that slides with the connecting ring.

[0010] The driving device is a dual-axis motor, and the other output shaft of the driving device is equipped with a synchronous structure, which includes two synchronous wheels and a synchronous belt connected between the two synchronous wheels. The two synchronous wheels are respectively connected and fixed to the output shaft of the driving device and one end of the quantitative rotor.

[0011] By adopting the above technical solution, the intermittent feeding equipment in this application can accurately control the amount of feeding each time, thereby ensuring that the fish oil enters the transfer equipment at a constant rate. This precise control helps to maintain the stability of the fish oil purification or processing process and improve product quality.

[0012] Furthermore, the fish oil sedimentation tank is tightly connected to the shell through a tight pipe, and the interior of the shell is hollow, with upper and lower sides communicated.

[0013] The beneficial effect of adopting the above further solution is that the fish oil sedimentation tank is tightly connected to the shell through a tight pipeline, ensuring that the oil outlet has good sealing performance and preventing the fish oil from leaking during storage and output.

[0014] Furthermore, a cavity adapted to the quantitative rotor is provided inside the shell, and the quantitative rotor and the cavity form a material separation cavity.

[0015] The beneficial effect of adopting the above further solution is that the quantitative rotor is always consistent with the material separation cavity inside the shell, and the amount of material discharged each time can be accurately controlled, thereby ensuring that the fish oil enters the transfer device at a constant rate and achieving quantitative discharge.

[0016] Furthermore, the quantitative rotor has an outer shape of two symmetrically distributed fan-shaped blocks, and a certain gap is left between the quantitative rotor and the cavity. Scraping strips are fixedly installed on both sides of the quantitative rotor closest to the cavity.

[0017] The beneficial effect of adopting the above further solution is that, by providing the scraping strips, the quantitative rotor can scrape off the materials remaining in the cavity when rotating, thereby ensuring the cleanliness of the cavity.

[0018] Furthermore, the bottom end of the shell is tightly connected to the top valve shell, the interior of the pump shell is hollow, and the inner walls of the two valve shells are both installed with limit platforms for limiting the one-way valve plate.

[0019] The beneficial effect of adopting the above further solution is that the one-way valve plate can be limited by setting the limit platform to prevent the one-way valve plate from excessively turning over due to the pressure difference.

[0020] Furthermore, a mounting plate for installing a drive motor is provided on the outside of the fish oil sedimentation tank, and the drive motor bolt is installed on the outer surface of the mounting plate. A limit seat for limiting the connecting rod is installed on the side of the mounting plate close to the connecting rod, and the connecting rod slides through the inside of the limit seat.

[0021] The beneficial effect of adopting the above further solution is that the connecting rod is limited by the limiting seat so that it can move back and forth linearly, thereby improving the stability when adjusting the piston block.

[0022] Furthermore, the transmission gear is meshed with the driven gear, and a connecting shaft connected to the mounting plate bearing is fixedly mounted on the back of the driven gear.

[0023] The beneficial effect of adopting the above further solution is that, by disposing the bearing, the stable rotation of the driven gear is ensured, thereby improving the transmission effect.

[0024] Furthermore, the interior of the connecting ring is hollow and its outer shape is in the shape of a racetrack, and the two synchronous wheels are of different sizes.

[0025] The beneficial effect of adopting the above further solution is that when the driven gear rotates, the sliding cooperation between the shaft and the connecting ring can drive the piston rod to move back and forth through the connecting rod, thereby realizing the suction work of the transfer equipment.

[0026] Compared with the prior art, the present application provides a sedimentation tank fish oil transfer device with the following beneficial effects:

[0027] 1. The intermittent feeding device of the sedimentation tank fish oil transfer device can accurately control the amount of material discharged each time, thereby ensuring that the fish oil enters the transfer device at a constant rate. This precise control helps maintain stability during the fish oil purification or processing process and improve product quality. In addition, combining the intermittent feeding device with the piston pump and ensuring their synchronous operation can significantly improve the efficiency, stability and flexibility of the fish oil purification or processing process, while reducing energy consumption and maintenance costs. This design is of great significance for improving product quality, reducing production costs and enhancing market competitiveness.

[0028] 2. The fish oil transfer device in the sedimentation tank, through the installation of a synchronous structure, enables the synchronous operation of the intermittent unloading equipment and the transfer equipment, which helps to optimize energy consumption. Since the unloading amount is precisely controlled, the transfer equipment can operate at lower energy consumption while reducing unnecessary energy waste. In addition, this design also helps to reduce noise and emissions, meeting environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figure 1 and Figure 2 A sedimentation tank fish oil transfer device includes a fish oil sedimentation tank 1, and the processing end of the fish oil sedimentation tank 1 is fixedly connected to an intermittent feeding device 2; the intermittent feeding device 2 includes a shell 21 and a quantitative rotor 23 rotatably arranged inside the shell 21; the fish oil sedimentation tank 1 is tightly connected to the shell 21 through a tight pipe, and the interior of the shell 21 is hollow, and its upper and lower sides are connected.

[0036] In this embodiment, the housing 21 defines a cavity adapted for the dosing rotor 23. The dosing rotor 23 and the cavity form a material separation chamber 22. The dosing rotor 23 is connected to a bearing within the cavity. During use, because the dosing rotor 23 is always aligned with the material separation chamber 22 within the housing 21, the amount of material discharged each time can be precisely controlled, ensuring that the fish oil enters the transfer device 3 at a constant rate, achieving a quantitative discharge effect.

[0037] Specifically, the dosing rotor 23 is configured as two symmetrically spaced sector blocks, with a gap between the dosing rotor 23 and the cavity. Scraping strips are fixedly mounted on both sides of the dosing rotor 23 closest to the cavity. These scraping strips allow the dosing rotor 23 to scrape away any remaining material in the cavity during rotation, ensuring a clean and tidy cavity.

[0038] See also Figure 1 and Figure 3The lower surface of the shell 21 is fixedly connected to the transfer device 3, which includes a pump shell 31, two valve shells 32 fixedly connected to opposite sides of the pump shell 31, a piston block 34 reciprocatingly arranged inside the pump shell 31, and a piston rod 33 fixedly installed on the outer surface of the piston block 34 and extending out of the pump shell 31. A one-way valve plate 35 is elastically hingedly installed in the two valve shells 32; the bottom end of the shell 21 is tightly connected to the top valve shell 32, the interior of the pump shell 31 is hollow, and the inner walls of the two valve shells 32 are installed with limit platforms for limiting the one-way valve plates 35.

[0039] See also Figure 1 and Figure 4 To drive the transfer device 3, in this embodiment, a drive device 4 for driving the transfer device 3 and the intermittent feeding device 2 is provided on the exterior of the fish oil sedimentation tank 1. The drive device 4 includes a drive motor 42, a transmission gear 43, a driven gear 44, and a connecting rod 45. One end of the connecting rod 45 is fixedly connected to the end of the piston rod 33, and a connecting ring 46 is welded to the other end of the connecting rod 45. A shaft 47 that slidably engages with the connecting ring 46 is fixedly mounted on the outer surface of the driven gear 44. A mounting plate 41 for mounting the drive motor 42 is provided on the exterior of the fish oil sedimentation tank 1. The mounting plate 41 is configured to contact the ground, thereby securing the drive device 4. The drive motor 42 is bolted to the outer surface of the mounting plate 41. A stopper 48 is mounted on the side of the mounting plate 41 near the connecting rod 45 to limit the position of the connecting rod 45. The connecting rod 45 slides through the interior of the stopper 48. The limiting seat 48 limits the connecting rod 45 so that it can move linearly back and forth, thereby improving the stability when adjusting the piston block 34.

[0040] Specifically, the transmission gear 43 meshes with the driven gear 44. A connecting shaft, bearing-connected to the mounting plate 41, is fixedly mounted on the back of the driven gear 44. The connecting ring 46 is hollow and has a racetrack-shaped exterior. When the driven gear 44 rotates, the sliding fit between the shaft and the connecting ring 46 drives the piston rod 33 back and forth via the connecting rod 45, thereby achieving the suction operation of the transfer device 3.

[0041] When the present embodiment is in use, the driving motor 42, the transmission gear 43 and the driven gear 44 drive the connecting rod 45 to reciprocate, and the displacement of the connecting rod 45 drives the piston block 34 to reciprocate through the piston rod 33. The reciprocating motion of the piston block 34 in the pump housing 31 changes the working volume in the pump housing cavity, thereby realizing the suction and discharge of liquid. When the piston block 34 moves outward, the outlet one-way valve plate 35 will be closed under the action of its own weight and pressure difference to prevent the liquid in the pump cavity from flowing back. At the same time, the inlet one-way valve plate 35 will open under the action of the pressure difference, so that the liquid can be When the piston block 34 is squeezed inwardly when being sucked into the pump chamber, the pressure in the pump chamber will increase. This increased pressure will cause the inlet reverse one-way valve plate 35 to close to prevent more liquid from entering the pump chamber. At the same time, the outlet one-way valve plate 35 will open to press the liquid in the pump chamber into the outlet valve housing, thereby realizing the discharge of the liquid. At the same time, the transmission cooperation of the synchronous wheel 51 and the synchronous belt 52 is utilized to realize the operation of the quantitative rotor 23. Since the quantitative rotor 23 is always consistent with the material separation chamber 22 inside the shell 21, the amount of material discharged each time can be accurately controlled, thereby ensuring that the fish oil enters the transfer device 3 at a constant rate.

[0042] It should be noted that the transfer device 3 works on the principle of a piston pump. The piston pump relies on the reciprocating motion of the piston in the pump cylinder to cause the working volume of the pump chamber to change periodically, thereby achieving the suction and discharge of liquid.

[0043] To improve structural linkage, see Figure 1 In this embodiment, the drive device 4 is a dual-shaft motor, and the other output shaft of the drive device 4 is equipped with a synchronous structure 5. The synchronous structure 5 includes two synchronous pulleys 51 and a synchronous belt 52 that is connected between the two synchronous pulleys 51. The two synchronous pulleys 51 are respectively connected and fixed to the output shaft of the drive device 4 and one end of the quantitative rotor 23. The two synchronous pulleys 51 are of different sizes. The installation of the synchronous structure 5 enables the synchronous operation of the intermittent unloading device 2 and the transfer device 3, which helps to optimize energy consumption. Since the unloading amount is precisely controlled, the transfer device can operate at lower energy consumption while reducing unnecessary energy waste. In addition, this design also helps to reduce noise and emissions, meeting environmental protection requirements.

[0044] The working principle of the above embodiment is:

[0045] When in use, first, the driving motor 42, the transmission gear 43 and the driven gear 44 drive the connecting rod 45 to reciprocate. The displacement of the connecting rod 45 drives the piston block 34 to reciprocate through the piston rod 33. The reciprocating motion of the piston block 34 in the pump housing 31 changes the working volume in the pump housing cavity, thereby realizing the suction and discharge of liquid. When the piston block 34 moves outward, the outlet one-way valve plate 35 will be closed under the action of its own weight and pressure difference to prevent the liquid in the pump cavity from flowing back. At the same time, the inlet one-way valve plate 35 will open under the action of the pressure difference, so that the liquid can be sucked into the pump cavity. When the block 34 is squeezed inward, the pressure in the pump chamber will increase. This increased pressure will cause the inlet check valve plate 35 to close to prevent more liquid from entering the pump chamber. At the same time, the outlet check valve plate 35 will open, pressing the liquid in the pump chamber into the outlet valve housing 32, thereby realizing the discharge of the liquid. Then, the transmission cooperation of the synchronous wheel 51 and the synchronous belt 52 is utilized to realize the operation of the quantitative rotor 23. Since the quantitative rotor 23 is always consistent with the material separation chamber 22 inside the housing 21, the amount of material discharged each time can be accurately controlled, thereby ensuring that the fish oil enters the transfer device 3 at a constant rate to realize quantitative discharging.
