DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-4 The utility model provides a technical solution: a fish oil deodorization device for treating the gas generated by the deodorization and distillation of fish oil, comprising:

[0031] A pipe fitting is provided with a feed end 3 and a discharge end 4;

[0032] A condensation component provided in the pipe fitting for condensing the gas entering the pipe fitting;

[0033] A gas filter assembly is provided in the pipe and close to the feed end 3, and is used to absorb harmful substances in the gas entering the pipe;

[0034] A liquid filter assembly is provided in the pipe and close to the discharge end 4, and is used to filter the liquid formed after the gas condenses;

[0035] The above technical solution can filter gas. When in use, the feed end 3 of the pipe is connected to the gas outlet end of the deodorizing kettle, and the discharge end 4 of the pipe is connected to the collecting device. After the fish oil is fed into the deodorizing kettle, the odorous substances in the fish oil are volatilized by high-temperature heating, and the volatilized gas enters the pipe through the feed end 3. Since a gas filter component is provided at the feed end 3, when the gas enters the pipe, it contacts the gas filter component, thereby absorbing harmful substances in the gas. Then, the volatilized odorous substances are condensed into liquid by the condensation component. After being filtered by the liquid filter component, the liquid flows into the collecting device through the discharge end 4, thereby avoiding adverse effects of harmful substances on human health during the fish oil deodorization process.

[0036] like Figure 2 As shown, in this embodiment, the filter component is an activated carbon plate 14;

[0037] By adopting the above technical solution, the activated carbon plate 14 can be used to absorb aldehydes and ketones in the gas.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, the pipe fitting includes a first pipe fitting 1 and a second pipe fitting 2 spliced ​​together, a feed end 3 is provided at one end of the second pipe fitting 2, and a discharge end 4 is provided at one end of the first pipe fitting 1;

[0039] The above technical solution can facilitate maintenance of the pipe fittings. The pipe fittings can be disassembled into the first pipe fitting 1 and the second pipe fitting 2, which is conducive to cleaning the inside of the first pipe fitting 1 and the second pipe fitting 2.

[0040] like Figure 3 As shown, in this embodiment, a first stopper 15 is provided on the inner wall of the second pipe fitting 2, and a second stopper 16 is provided on the inner wall of the first pipe fitting 1 to cooperate with the first stopper 15. A clamping space for clamping the activated carbon plate 14 is formed between the first stopper 15 and the second stopper 16. The outer diameter of the second pipe fitting 2 is less than or equal to the inner diameter of the first pipe fitting 1. A side groove 19 is provided on the side wall of the second pipe fitting 2 to engage with the second stopper 16. A bolt hole 18 is provided at the connection between the first pipe fitting 1 and the second pipe fitting 2, and a bolt 17 is provided in the bolt hole 18.

[0041] The above technical solution can facilitate the replacement of the activated carbon plate 14. When the adsorption effect of the activated carbon plate 14 decreases after being used for a period of time, the bolt 17 can be removed from the bolt hole 18 using a tool, and the right end of the second pipe fitting 2 can be pulled out from the left end of the first pipe fitting 1, thereby releasing the clamping of the activated carbon plate 14 by the first limit member 15 and the second limit member 16. Since the side of the second pipe fitting 2 is provided with a side groove 19, after the second pipe fitting 2 is inserted into the first pipe fitting 1, the second limit member 16 can be embedded in the side groove 19, thereby aligning the bolt holes 18 between the first pipe fitting 1 and the second pipe fitting 2, making it convenient to install the bolt 17.

[0042] like Figure 2 As shown, in this embodiment, the liquid filtering component is a sieve plate 20 provided at the discharge end 4 of the first pipe member 1;

[0043] The above technical solution can filter the liquid formed after the gas condenses. When the gas is filtered through the condensation component to form liquid, after the liquid flows through the sieve plate 20, the sieve plate 20 will filter the solid impurities in the liquid to achieve filtration of the liquid.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the condensing assembly further includes: a mounting plate 5 with mounting holes 6, the mounting plates 5 having at least two portions to form a water-cooling space in the first pipe 1; a water inlet end 12 and a water outlet end 13 connected to the water-cooling space; a condensing pipe 7 and plugs 8 provided at both ends of the condensing pipe 7, the plugs 8 engaging with the mounting holes 6;

[0045] The above technical solution can condense the gas. After the gas is filtered through the activated carbon plate 14, it will enter the condenser 7 along the mounting hole 6 on the surface of the mounting plate 5. At this time, cold water enters the water-cooled space from the water inlet end 12, thereby cooling the condenser 7, so that the gas entering the condenser 7 is liquefied into liquid, and the liquid flows out through the other end of the condenser 7.

[0046] like Figure 4 As shown, in this embodiment, a channel 10 is opened inside the condenser tube 7, and the channel 10 passes through the inlet end and the outlet end of the condenser tube 7. The aperture of the channel 10 gradually increases from the inlet end to the outlet end to form a trumpet-shaped structure.

[0047] The above technical solution can facilitate the liquid to flow out of the condenser tube 7, and give the channel 10 of the condenser tube 7 a certain slope to prevent liquid from accumulating in the channel 10.

[0048] like Figure 4 As shown, in this embodiment, a dense corrugated plate 11 is provided on the upper end of the inner wall of the channel 10, and a one-way valve 9 is provided at both the inlet and outlet ends of the condenser pipe 7;

[0049] The above technical solution can fully condense the gas. Since the inner wall of the condenser tube 7 is provided with a corrugated plate 11, the corrugated plate 11 can increase the contact area between the condenser tube 7 and the gas, thereby fully condensing the gas. The setting of the one-way valve 9 is conducive to preventing the backflow of gas or liquid, that is, ensuring that the gas entering the condenser tube 7 no longer flows back, and the liquid does not flow back into the condenser tube 7 after being discharged from the condenser tube 7.

[0050] Working principle: When in use, first connect the feed end 3 of the pipe fitting to the gas outlet end of the deodorizing kettle, and connect the discharge end 4 of the pipe fitting to the collecting device. After the fish oil is fed into the deodorizing kettle, the odorous substances in the fish oil are volatilized by high-temperature heating. The volatilized gas enters the pipe fitting through the feed end 3. Since an activated carbon plate 14 is provided at the feed end 3, the activated carbon plate 14 absorbs aldehydes and ketones in the gas, thereby absorbing harmful substances in the gas. After the gas is filtered by the activated carbon plate 14, it will enter the condenser 7 along the mounting hole 6 on the surface of the mounting plate 5. At this time, cold water enters the water-cooled space from the water inlet end 12, thereby cooling the condenser 7, so that the gas entering the condenser 7 is liquefied into liquid. The liquid flows out through the other end of the condenser 7. The trumpet-shaped channel 10 of the condenser 7 gives the liquid a slope for flow, preventing liquid from accumulating in the channel 10. Since the inner wall of the condenser 7 is provided with a corrugated plate 11, the corrugated plate 11 can increase the contact area between the condenser 7 and the gas, thereby fully condensing the gas. The setting of the one-way valve 9 is conducive to preventing gas or liquid reflux, that is, ensuring that the gas entering the condenser 7 no longer flows back, and the liquid no longer flows back into the condenser 7 after being discharged from the condenser 7. After the liquid flows through the sieve plate 20, the sieve plate 20 will filter the solid impurities in the liquid to achieve filtration of the liquid. The filtered liquid flows into the collection device, thereby avoiding the adverse effects of harmful substances on human health during the deodorization of fish oil.
