Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fish oil delivery, and particularly relates to a protection device for a fish oil delivery pipeline. BACKGROUND

[0002] Fish oil refers to oil prepared by taking fish as raw material, which includes fish body oil and fish liver oil. Fish oil has a high proportion of highly unsaturated fatty acids in the composition of fatty acids. Eicosapentaenoic acid and docosahexaenoic acid in the highly unsaturated fatty acids are active substances for reducing high blood lipids, and 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, the fish oil needs to be delivered from one processing equipment to another processing equipment through a pipeline. In actual application, it is difficult to achieve 100% transfer of fish oil, and part of the fish oil often remains in the pipeline. When the fish oil production line needs to be shut down for a period of time, the residual fish oil in the pipeline reacts with the air in the pipeline and easily corrodes and damages the pipeline, thereby shortening the service life of the pipeline. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the problem that the residual fish oil in the delivery pipeline causes the pipeline to age faster, the present application provides a protection device for a fish oil delivery pipeline.

[0005] The present application provides a protection device for a fish oil delivery pipeline, which adopts the following technical scheme:

[0006] The protection device for the fish oil delivery pipeline is used for protecting the delivery pipeline, both ends of the delivery pipeline are provided with a first valve, and the protection device comprises a gas pump, a gas delivery pipe and a second valve. One end of the gas delivery pipe is connected in communication with the gas pump, the other end of the gas delivery pipe is in communication with one end of the delivery pipeline close to a delivery starting point of the delivery pipeline, and the second valve is arranged on the gas delivery pipe.

[0007] By adopting the above technical scheme, the gas pump blows gas into the delivery pipeline through the gas delivery pipe. After the gas enters the delivery pipeline, the residual fish oil in the delivery pipeline is driven to move to the next equipment, so that the amount of the residual fish oil in the delivery pipeline can be reduced, and then the intensity of the reaction between the residual fish oil and the air in the delivery pipeline is reduced, and the speed of the corrosion and damage of the delivery pipeline caused by the reaction between the fish oil and the air is reduced.

[0008] Optionally, the protection device further comprises a connecting pipe, an inner diameter size of the gas delivery pipe is smaller than an inner diameter size of the connecting pipe, the inner diameter size of the connecting pipe is the same as an inner diameter size of the delivery pipeline, one end of the connecting pipe is connected in communication with one end of the gas delivery pipe away from the gas pump, and the other end of the connecting pipe is connected in communication with the delivery pipeline.

[0009] By adopting the above technical solution, the gas supply pipe is connected to the delivery pipeline through the connecting pipe, which makes the process of connecting the gas supply pipe and the delivery pipeline more convenient; in addition, the gas moves at a greater speed in the pipe with a smaller inner diameter, which makes the gas speed entering the connecting pipe from the gas supply pipe faster, thereby making the gas blowing and driving the fish oil move better.

[0010] Optionally, the end of the connecting pipe near the gas transmission pipe is an arc-shaped pipe section.

[0011] By adopting the above technical solution, when the gas enters the connecting pipe from the gas supply pipe, the arc-shaped pipe section can guide the gas to change its direction of movement, thereby reducing the speed loss during the process of changing the direction of movement. This allows the gas to have a faster movement speed after entering the connecting pipe, improving the effect of gas blowing to drive the fish oil to move.

[0012] Optionally, the connection point between the gas supply pipe and the connecting pipe is located at the top of the connecting pipe.

[0013] By adopting the above technical solution, when the fish oil remaining in the delivery pipeline flows into the connecting pipe to the end of the connecting pipe away from the delivery pipeline, the fish oil is less likely to flow into the gas delivery pipe, thereby reducing the probability of fish oil entering the gas delivery pipe and causing blockage.

[0014] Optionally, the end of the delivery pipe away from the gas delivery pipe has an observation window.

[0015] By adopting the above technical solution, staff can observe the internal situation of the end of the delivery pipeline away from the gas pipe through the observation window, thereby knowing how the gas blows the fish oil and drives it to move after entering the delivery pipeline, and thus determining when the air pump should stop working, reducing energy waste.

[0016] Optionally, the observation window is located at the end of the delivery process on the side of the first valve away from the gas delivery pipe.

[0017] By adopting the above technical solution, the gas passes through the first valve at the end of the delivery pipeline and then through the observation window. This ensures that when the staff observes the residual fish oil inside the delivery pipeline through the observation window, the residual fish oil at the first valve at the end of the delivery pipeline will not be more severe than what the staff observes, thereby improving the accuracy of the conclusions drawn by the staff.

[0018] Optionally, the observation window is located at the top of the delivery pipe.

[0019] By adopting the above technical solution, when staff observe the residual fish oil inside the conveying pipe through the observation window, they can directly see the bottom of the conveying pipe, which facilitates observation.

[0020] Optionally, the gas transported by the gas pump through the gas conveying pipe is nitrogen.

[0021] By using the above technical scheme, opening the first valve at the conveying terminal end uses the gas to blow the residual fish oil in the conveying pipeline away, at the same time, the nitrogen concentration in the conveying pipeline is increased, so that the intensity of the reaction between the fish oil and the oxygen in the air is reduced, and the aging speed of the pipeline is further slowed down.

[0022] Optionally, the device further comprises a detection member for detecting the nitrogen concentration, and the detection member is arranged on the gas conveying pipe.

[0023] By using the above technical scheme, the detection member can detect the nitrogen concentration in the gas conveying pipe, and when the gas fills the conveying pipeline, the detection member can help the staff to know the degree of blowing in of the nitrogen, so as to determine the timing of stopping the gas pump, thereby further reducing the waste of energy.

[0024] Optionally, the detection member is located on the side of the second valve away from the conveying pipeline.

[0025] By using the above technical scheme, if the detection member detects that the nitrogen concentration in the gas conveying pipe reaches a certain standard, the nitrogen concentration in the gas conveying pipe at the second valve also reaches the certain standard, so that the accuracy of the staff judging whether the amount of blowing in of the nitrogen is sufficient or not according to the detection member is improved.

[0026] In summary, the present application has at least one of the following beneficial effects:

[0027] 1. By blowing in the gas, the residual fish oil in the conveying pipeline can be moved to the next equipment, so that the amount of residual fish oil in the conveying pipeline is reduced, and the probability of the residual fish oil in the conveying pipeline reacting with the air to cause the conveying pipeline to age and be damaged at a faster speed is reduced.

[0028] 2. While part of the residual fish oil in the conveying pipeline is blown away by the gas, the nitrogen fills into the conveying pipeline to increase the nitrogen concentration in the conveying pipeline, so that the probability of the residual fish oil in the conveying pipeline reacting with the air to cause the conveying pipeline to age and be damaged at a faster speed is reduced.

[0032] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0033] Example 1:

[0034] Reference Figure 1 This application discloses a protective device for a fish oil delivery pipeline, used to protect the delivery pipeline 1 and reduce the rate at which the delivery pipeline 1 ages and is damaged due to the reaction of residual fish oil inside with air.

[0035] The protective device includes an air pump 2 and an air supply pipe 3. Both ends of the air supply pipe 3 are connected to the air pump 2 and the delivery pipeline 1, respectively. The connection point between the air supply pipe 3 and the delivery pipeline 1 is near the starting point of the delivery pipeline 1. The air pump 2 blows gas into the delivery pipeline 1 through the air supply pipe 3. After entering the delivery pipeline 1, the gas can agitate the residual fish oil inside the delivery pipeline 1 and drive it to move along the delivery direction. Furthermore, the gas can inhibit the reaction between the residual fish oil inside the delivery pipeline 1 and the air, thus providing a protective function. In this embodiment, nitrogen is preferably used as the gas blown into the air supply pipe 3 by the air pump 2. In other embodiments, other gases that do not readily react with fish oil can also be used.

[0036] The protective device also includes a connecting pipe 4. The end of the gas supply pipe 3 furthest from the air pump 2 is connected to the connecting pipe 4, and the end of the connecting pipe 4 furthest from the gas supply pipe 3 is connected to the end of the conveying pipeline 1 where the conveying start point is located. The inner diameter of the gas supply pipe 3 is smaller than the inner diameter of the conveying pipeline 1. The inner diameter of one end of the connecting pipe 4 is equal to the inner diameter of the gas supply pipe 3, and the inner diameter of the other end of the connecting pipe 4 is equal to the inner diameter of the conveying pipeline 1. In this embodiment, it is preferable that all pipes are connected by welding.

[0037] The air pump 2 is fixedly installed on the ground. After the delivery pipe 1, the air supply pipe 3 and the connecting pipe 4 are installed, the delivery pipe 1 is located above the air pump 2. The connection point between the air supply pipe 3 and the connecting pipe 4 is located at the top of the delivery pipe 1. The direction of gas movement from the air supply pipe 3 into the connecting pipe 4 is vertical and perpendicular to the length direction of the delivery pipe 1.

[0038] The end of the connecting pipe 4 near the gas transmission pipe 3 is an arc-shaped pipe section 41. After the gas enters the connecting pipe 4 from the gas transmission pipe 3, the arc-shaped pipe section 41 can guide the gas to change its direction of movement, so that the gas moves from the connecting pipe 4 into the transmission pipe 1 in a direction parallel to the length of the transmission pipe 1.

[0039] The first valve 5 is fixedly installed on both ends of the conveying pipeline 1, and the connecting position of the connecting pipe 4 and the conveying pipeline 1 is located between the two first valves 5 and close to the first valve 5 at the conveying starting point. The protection device further comprises a second valve 6 fixedly installed on the gas conveying pipe 3. In the embodiment, the first valve 5 and the second valve 6 are preferably manual valves, and since the valve is a common prior art, it is not described here.

[0040] The implementation principle of the protection device for the fish oil conveying pipeline in the embodiment of the application is as follows:

[0041] When the first valve 5 at the conveying terminal of the conveying pipeline 1 is opened and the first valve 5 at the conveying starting point is closed, the gas pump 2 blows nitrogen into the conveying pipeline 1 through the gas conveying pipe 3 and the connecting pipe 4. After the nitrogen enters the conveying pipeline 1, the residual fish oil in the conveying pipeline 1 can be blown away from the conveying terminal, so that the amount of residual fish oil in the conveying pipeline 1 is reduced, thereby reducing the influence of the reaction of the residual fish oil and air on the conveying pipeline 1. Moreover, after the nitrogen enters the conveying pipeline 1, the nitrogen concentration in the air of the conveying pipeline 1 rises. When the nitrogen concentration rises to a certain value, the reaction of the residual fish oil and air in the conveying pipeline 1 can be effectively inhibited, thereby further reducing the influence of the reaction of the residual fish oil and air on the conveying pipeline 1, and prolonging the service life of the conveying pipeline 1.

[0042] Embodiment 2:

[0043] The embodiment is optimized on the basis of embodiment 2, so as to facilitate the staff to control the opening and closing time of the gas pump 2 and reduce the waste of energy.

[0044] With reference to Figure 2 , an observation pipe 7 is further fixedly installed on the conveying pipeline 1, the observation pipe 7 is located on the side of the first valve 5 at the conveying terminal away from the connecting pipe 4, and the observation pipe 7 is provided with an observation window 71 for the staff to observe the internal condition of the conveying pipeline 1. The opening of the observation window 71 is vertically upward, and the staff can observe the condition of the residual fish oil at the bottom of the conveying pipeline 1 through the observation window 71 above the observation pipe 7. When the staff observes that the residual fish oil in the conveying pipeline 1 at this position has been basically blown away by the gas, the staff can judge that the residual fish oil in the part of the conveying pipeline 1 between the observation window 71 and the connecting pipe 4 has also been basically blown away by the gas.

[0045] The protection device further comprises a detecting member 8 for detecting the concentration of nitrogen, which is fixedly installed on the gas conveying pipe 3 and located at the side of the second valve 6 away from the connecting pipe 4. In the process of gas entering the connecting pipe 4 through the gas conveying pipe 3, the gas first passes through the detecting member 8 and then the second valve 6. In the embodiment, the detecting member 8 is a common prior art, and thus is not described here.

[0046] When the staff judges that the residual fish oil in the conveying pipeline 1 has been basically blown away by the gas through the observation window 71, the first valve 5 at the conveying terminal is closed and the gas pump 2 is controlled to stop working. Then, the stable value detected by the detecting member 8 is observed, and whether the nitrogen concentration in the conveying pipeline 1 at this time can effectively inhibit the reaction of residual fish oil with air is judged according to the value. If yes, the second valve 6 is closed, and the two first valves 5 and the second valve 6 are opened again when the conveying pipeline 1 needs to be used next time. If no, the first valve 5 at the conveying terminal is opened again, the gas pump 2 is controlled to continue working to blow gas into the conveying pipeline 1, and the above steps are repeated after a period of time for retesting until the nitrogen concentration in the conveying pipeline 1 meets the condition.

[0047] The implementation principle of the protection device for the fish oil conveying pipeline according to the embodiment of the present application is as follows:

[0048] The staff can judge whether the gas blown into the conveying pipeline 1 has basically blown away the residual fish oil in the conveying pipeline 1 through the observation window 71, and can judge whether the nitrogen blown into the conveying pipeline 1 is sufficient according to the detecting member 8, so as to facilitate the staff to determine the timing of opening and closing the gas pump 2 and reduce energy loss.

[0049] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
