Description

Technical Field

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

[0002] Fish oil refers to oil derived from fish, including fish body oil and cod liver oil. Fish oil contains a high proportion of highly unsaturated fatty acids. Eicosapentaenoic acid and docosahexaenoic acid, two of these fatty acids, are active substances that can lower high blood lipids. Fish oil is also rich in nutrients such as vitamin A and vitamin D, and has high medicinal value.

[0003] During the production and processing of fish oil, a process of settling is used to initially improve its purity. This is typically done by placing the oil in a settling tank. After a period of time, impurities in the oil settle to the bottom of the tank, causing the oil to separate into layers. The upper layer contains the purer fish oil, while the lower layer contains unwanted impurities. Once the oil has settled in the tank, the impurities are removed through a pipeline, completing the initial purification of the oil.

[0004] However, in the process of discharging impurities through the pipeline, impurities deposited at the bottom of the sedimentation tank far away from the pipeline are difficult to be discharged through the pipeline, which will reduce the effect of the initial purification of fish oil by the static sedimentation method. Utility Model Content

[0005] In order to improve the effect of preliminary purification of fish oil by static sedimentation, the present application provides a fish oil sedimentation tank.

[0006] This application provides a fish oil sedimentation tank, which adopts the following technical solution:

[0007] A fish oil sedimentation tank comprises a tank body, a discharge pipe, an impurity pipe, a fish oil pipe, a first valve and a second valve. The discharge pipe is located below the tank body, and the bottom of the tank body has a conical structure, which is tapered toward the discharge pipe. The upper end of the discharge pipe is connected to the bottom of the conical structure; one end of the impurity pipe and the fish oil pipe are both connected to the lower end of the discharge pipe, the other end of the impurity pipe leads to a discarding device, and the other end of the fish oil pipe leads to a subsequent fish oil processing device. The first valve is arranged at one end of the impurity pipe close to the discharge pipe, and the second valve is arranged at one end of the fish oil pipe close to the discharge pipe.

[0008] By adopting the above technical solution, after the fish oil has been precipitated in the tank body, impurities will be deposited inside the conical structure. When the first valve is opened and the second valve is closed, the impurities deposited inside the conical structure can be discharged through the impurity pipe. The conical structure can accelerate the discharge of impurities and reduce the probability of impurities being discharged incompletely from the tank body, thereby improving the effect of the preliminary purification of fish oil by the static sedimentation method. After the impurities have been discharged for a certain period of time, the first valve is closed and the second valve is opened, and the fish oil with higher purity can be transported to other processing equipment through the fish oil pipe for subsequent processing of the fish oil.

[0009] Optionally, an observation assembly is also included, which includes a cylinder, several covers and several perspective mirrors. The cylinder has a cavity inside, the cylinder is arranged on the discharge pipe, and the discharge pipe is communicated with the cavity; the cover is connected to the cylinder, and the cover has an observation port, which is communicated with the cavity, and the perspective mirror is connected to the cover and covers the observation port.

[0010] By adopting the above technical solution, during the process of discharging impurities through the impurity pipe, the staff can observe the substances passing through the cavity through the perspective mirror, thereby judging the progress of impurity discharge in the tank body, which is convenient for the staff to judge the opening and closing timing of the first valve and the second valve, thereby ensuring that the impurities can be discharged completely and reducing the waste caused by the discharge of fish oil through the impurity pipe.

[0011] Optionally, the observation assembly further includes a movable cleaning member, which is located on a side of the perspective mirror close to the cavity, and the cleaning member abuts against the perspective mirror.

[0012] By adopting the above technical solution, when the perspective mirror is dirty due to contact with impurities, making it difficult for the staff to observe the material passing through the cavity through the perspective mirror, the cleaning piece can be used to clean the perspective mirror, reducing the dirt on the surface of the perspective mirror, making it easier for the staff to continue to observe the material passing through the cavity.

[0013] Optionally, the observation assembly further includes a rotating member and a control member, wherein the rotating member is rotatably connected to the cover body, the rotation axis of the rotating member is parallel to the axis of the cylinder, and the cleaning member is arranged on the rotating member; the control member is also rotatably connected to the cover body, the control member is partially located on the outside of the cover body, and the rotation of the control member drives the rotating member to rotate.

[0014] By adopting the above technical solution, the rotation of the control member located outside the cover body can be controlled to drive the rotating member to rotate, and the rotation of the rotating member can drive the cleaning member to clean the perspective mirror, making it more convenient for the staff to clean the perspective mirror.

[0015] Optionally, the rotating member has a connecting portion, and the cleaning member is detachably connected to the connecting portion.

[0016] By adopting the above technical solution, the cleaning piece needs to be replaced after being used for a period of time, and the connecting portion can facilitate the disassembly and assembly of the cleaning piece.

[0017] Optionally, the color of the connecting portion is the same as the color of the substance passing through the cavity after the impurities are discharged.

[0018] By adopting the above technical solution, when the staff observes the situation of the material passing through the cavity through the perspective mirror, they can use the color of the connecting part as a reference to judge the discharge of impurities in the tank body, thereby enabling the staff to control the opening and closing timing of the first valve and the second valve more accurately.

[0019] Optionally, a third valve is further included, which is arranged on the discharge pipe and located between the tank body and the observation assembly.

[0020] By adopting the above technical solution, when the staff determines that the impurities in the tank body have been completely discharged based on the material conditions in the cavity observed through the perspective mirror, they first close the first valve, then close the third valve, and then open the first valve. This can ensure that the impurities in the discharge pipe that have not yet been discharged are discharged, thereby further improving the purity of the fish oil transported through the fish oil pipe.

[0021] Optionally, there are multiple covers and multiple perspective mirrors.

[0022] By adopting the above technical solution, workers at different positions around the discharge pipe can observe the situation of the material passing through the cavity through the perspective mirror, which further facilitates the workers' observation.

[0023] Optionally, the radial dimension of the cavity is larger than the inner diameter of the discharge pipe.

[0024] By adopting the above technical solution, the amount of material passing through the cavity can be increased, making it easier for staff to observe the situation of the material passing through the cavity through the perspective mirror, making the observation clearer, and further improving the accuracy of judging the progress of impurity discharge inside the tank.

[0025] Optionally, the minimum inner diameter of the conical structure is equal to the inner diameter of the discharge pipe.

[0026] By adopting the above technical solution, impurities deposited inside the conical structure can move along the inner wall of the conical structure and directly enter the discharge pipe, effectively avoiding the situation where the impurities remain on the flat part at the bottom of the conical structure during the discharge process, thereby improving the effect of impurity discharge and further improving the effect of preliminary purification of fish oil by static sedimentation.

[0027] In summary, this application has at least one of the following beneficial effects:

[0028] 1. During the process of discharging impurities through the discharge pipe, the impurities can enter the discharge pipe along the inner wall of the tapered structure, which can make the impurities discharged more completely and accelerate the speed of impurity discharge, thereby improving the effect of impurity discharge and further improving the effect of the initial purification of fish oil by the static sedimentation method;

[0029] 2. By observing the components, the staff can judge the discharge status and progress of impurities in the tank, thereby ensuring that the impurities deposited in the tank can be completely discharged, and also reducing the waste caused by the accidental discharge of fish oil.

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The embodiment of the present application discloses a fish oil sedimentation tank.

[0036] Reference Figure 1The fish oil sedimentation tank includes a tank body 1, a discharge pipe 2, an observation component 3, an impurity pipe 4 and a fish oil pipe 5. The discharge pipe 2 is located below the tank body 1, and the upper end of the discharge pipe 2 is connected to the tank body 1; the observation component 3 is fixedly mounted on the discharge pipe 2; one end of the impurity pipe 4 is connected to the lower end of the discharge pipe 2, and the other end of the impurity pipe 4 leads to the discard area; one end of the fish oil pipe 5 is connected to the lower end of the discharge pipe 2, and the other end of the fish oil pipe 5 leads to the processing equipment for the subsequent process steps of the fish oil. After the fish oil is allowed to settle inside the tank body 1, the impurities in the lower layer can be discharged to the discard area for collecting impurities through the discharge pipe 2 and the impurity pipe 4. The staff observes the situation of the material passing through the discharge pipe 2 through the observation component 3. After judging that the impurities are discharged, the fish oil in the upper layer is transported to the next processing equipment through the discharge pipe 2 and the fish oil pipe 5 for subsequent processes.

[0037] The tank 1 is suspended from a support frame fixed to the ground. The bottom of the tank 1 has a tapered structure 11. The inner diameter of the tapered structure 11 near the ground is smaller than the inner diameter of the tapered structure 11 away from the ground. A discharge pipe 2 is vertically mounted below the tank 1. The end of the discharge pipe 2 is fixedly connected to the bottom of the tapered structure 11. The inner diameter of the tapered structure 11 near the ground is the same as the inner diameter of the discharge pipe 2.

[0038] The fish oil settling tank also includes a first valve 6, a second valve 7, and a third valve 8 for controlling the flow of fluid through the pipeline. The first valve 6 is fixedly mounted on the end of the impurity pipe 4 near the discharge pipe 2, the second valve 7 is fixedly mounted on the end of the fish oil pipe 5 near the discharge pipe 2, and the third valve 8 is fixedly mounted on the discharge pipe 2, located between the tapered structure 11 and the observation assembly 3. In this embodiment, the first valve 6, the second valve 7, and the third valve 8 are preferably all manual valves. Since manual valves are common in the prior art, they will not be described in detail here.

[0039] When impurities need to be discharged, the first valve 6 and the third valve 8 are opened, and the second valve 7 is closed; when it is determined by observing the component 3 that the impurities are discharged, the first valve 6 is closed first, then the third valve 8 is closed, and then the first valve 6 is opened again to discharge the impurities remaining in the discharge pipe 2 and the impurity pipe 4; when the fish oil needs to be transported to the next equipment, the second valve 7 and the third valve 8 are opened, and the first valve 6 is closed.

[0040] Reference Figure 1 and Figure 2 The observation component 3 includes a cylinder 31, a plurality of covers 32 and a plurality of perspective mirrors 33. In this embodiment, the observation component 3 preferably includes two covers 32 and two perspective mirrors 33. In other embodiments, the number of covers 32 and perspective mirrors 33 may be greater.

[0041] The barrel 31 has a cavity 311 inside. Cavity 311 extends through both ends of the barrel 31 along its axis, forming openings. The inner diameter of cavity 311 is much larger than the inner diameter of discharge tube 2. After installation, barrel 31 divides discharge tube 2 into two sections, both of which communicate with cavity 311. The axis of barrel 31 is perpendicular to the axis of discharge tube 2. A cover 32 is fixedly connected to barrel 31 and mounted at the two openings of barrel 31. Each cover 32 has an observation port 321 that communicates with cavity 311. A perspective mirror 33 is fixedly mounted on cover 32 and covers observation port 321, allowing personnel to observe the passage of material in cavity 311 through perspective mirror 33.

[0042] Reference Figure 2 and Figure 3 The observation assembly 3 also includes two cleaning parts 34, two rotating parts 35 and two control parts 36. The two cleaning parts 34, the two rotating parts 35 and the two control parts 36 are respectively installed on different covers 32. The rotating part 35 is located on the side of the perspective mirror 33 close to the cavity 311. The rotating part 35 is rotatably connected to the cover 32, and the rotation axis of the rotating part 35 coincides with the axis of the cylinder 31. After the rotating part 35 is installed, there is a distance between the rotating part 35 and the perspective mirror 33; the control part 36 is also rotatably connected to the cover 32, and the rotation axis of the control part 36 is parallel to the rotation axis of the rotating part 35. Part of the control part 36 is located inside the cover 32, and the other part is located outside the cover 32. The rotation of the control part 36 can drive the rotation of the rotating part 35. In this embodiment, it is preferred that the control part 36 and the rotating part 35 both have a gear structure, and the linkage is achieved through gear meshing.

[0043] The rotating member 35 is annular in structure, and has a rod-shaped connecting portion 351 at its center. The cleaning member 34 is also strip-shaped, and the cleaning member 34 is detachably connected to the connecting portion 351. In this embodiment, the cleaning member 34 and the connecting portion 351 are preferably detachably connected by a plurality of screws.

[0044] One end of the cleaning member 34 has a plurality of soft bristles. After the cleaning member 34 is installed and fixed on the connecting portion 351, the bristles contact and abut against the perspective mirror 33. The rotation of the rotating member 35 can drive the cleaning member 34 to rotate around the rotation axis of the rotating member 35, thereby cleaning the end face of the perspective mirror 33 close to the cavity 311.

[0045] The connecting portion 351 has a specific color. When the color of the material passing through the cavity 311 matches the color of the connecting portion 351, the impurities inside the tank body 1 are completely discharged. When the staff observes the material passing through the cavity 311 through the perspective mirror 33, they can use the color of the connecting portion 351 as a reference to determine the progress of the impurities discharged from the tank body 1.

[0046] The implementation principle of a fish oil sedimentation tank in the embodiment of the present application is as follows:

[0047] After the fish oil has been precipitated inside the tank body 1, the first valve 6 and the third valve 8 are opened first, and the second valve 7 remains closed, so that the impurities in the lower layer can enter the discharge pipe 2 along the inner wall of the tapered structure 11 and then be discharged to the discard area for collection through the impurity pipe 4; during the impurity discharge process, the staff observes the situation of the substance passing through the cavity 311 through the perspective mirror 33, and can judge the situation and progress of the impurity discharge in the tank body 1 by referring to the color of the connecting portion 351; when the color of the substance passing through the cavity 311 is the same as the color of the connecting portion 351, the impurities inside the tank body 1 are discharged completely, the first valve 6 is closed first, then the third valve 8 is closed, and then the first valve 6 is opened again to discharge the impurities remaining in the discharge pipe 2 and the impurity pipe 4; then the second valve 7 and the third valve 8 are opened, and the first valve 6 remains closed, so that the fish oil in the upper layer can be transported to the subsequent fish oil processing equipment through the discharge pipe 2 and the fish oil pipe 5 for subsequent processing.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
