Description

Technical Field

[0001] This utility model belongs to the technical field of crude fish oil alkali refining equipment, specifically a pipeline crude fish oil alkali refining equipment. Background Technology

[0002] In the production of fishmeal, fish scraps and other byproducts need to be pressed to separate oil, water, and fish residue. The fish residue is used to make fishmeal, while the oil is used to make crude fish oil. The first step in making crude fish oil is to remove the acid from the oil.

[0003] A search revealed a patent with application number 202322102610X that discloses a pipeline-type crude fish oil alkali refining device. In use, oil and alkali enter a mixing pipe, where they are mixed by a mixing pump. This neutralizes the acid in the oil with the alkali. Due to the large amount of alkali, both the neutralized oil and water become alkaline. A centrifuge then separates the water and oil, leaving the oil alkaline. A washing machine then flushes water into the oil, dissolving the alkali in it. The oil and water are then flushed into an evaporator at 150 degrees Celsius, where the water carrying the alkali evaporates rapidly, thus removing the remaining alkali from the oil and meeting production requirements.

[0004] However, when the above-mentioned device is in use, the oil and water inside the evaporator remain stagnant during the high-temperature evaporation process, and the oil floats on the water surface. It takes a long time to completely evaporate the water carrying alkali, resulting in low alkali refining efficiency of the fish oil. Summary of the Invention

[0005] The purpose of this invention is to provide a pipeline-type crude fish oil alkali refining device, which can increase the evaporation rate of water in the oil, thereby improving the alkali refining efficiency of crude fish oil.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pipeline-type crude fish oil alkali refining device is provided, comprising a mixing pump, a tubular centrifuge, and an evaporator.

Heating plates are fixedly connected inside the multiple first guide plates and the two second guide plates. Circular holes are opened on the lower end face of the two second guide plates. A heat insulation plate is fixedly connected to the circumferential surface of the rear side of the evaporator. A high-temperature resistant oil pump is fixedly connected to the rear end of the heat insulation plate. A third inlet pipe is fixedly connected to the inlet end of the high-temperature resistant oil pump.

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to Figures 1-4This invention provides a description of a pipeline-type crude fish oil alkali refining device. The pipeline-type crude fish oil alkali refining device includes a mixing pump 1, a tubular centrifuge 3, and an evaporator 8. A T-shaped pipe 2 is fixedly connected to the inlet end of the mixing pump 1, and a first inlet pipe 4 is fixedly connected to the outlet end of the mixing pump 1. The end of the first inlet pipe 4 away from the mixing pump 1 is fixedly connected to the tubular centrifuge 3 and communicates with it. An oil outlet pipe 5 is fixedly connected to the circumferential surface on the right side of the tubular centrifuge 3. A water washing tank 6 is fixedly connected to the right end of the oil outlet pipe 5. A second inlet pipe 9 and a first valve 18 are fixedly connected to the bottom end of the water washing tank 6. The end of the second inlet pipe 9 away from the water washing tank 6 is fixedly connected to the evaporator 8. A water pump 10 is fixedly connected to the upper end of the evaporator 8. The outlet end of the water pump 10 extends downward into the evaporator 8, and the inlet end of the water pump 10 is fixedly connected to the second inlet pipe 9. Multiple first valves are fixedly connected to the inner wall of the evaporator 8. A guide plate 12 and two second guide plates 13 are provided. Each second guide plate 13 is located between two adjacent first guide plates 12. A heating plate 15 is fixedly connected inside the multiple first guide plates 12 and the two second guide plates 13. A circular hole 14 is opened on the lower end face of the two second guide plates 13. A heat insulation plate 22 is fixedly connected to the circumferential surface of the rear side of the evaporator 8. A high-temperature resistant oil pump 16 is fixedly connected to the rear end of the heat insulation plate 22. A third liquid inlet pipe 17 is fixedly connected to the liquid inlet end of the high-temperature resistant oil pump 16. The third liquid inlet pipe 17 extends forward into the evaporator 8 and is fixedly connected to the evaporator 8. A second liquid outlet pipe 11 is fixedly connected to the liquid outlet end of the high-temperature resistant oil pump 16. The second liquid outlet pipe 11 extends downward into the evaporator 8, and the end of the second liquid outlet pipe 11 away from the high-temperature resistant oil pump 16 is located directly above the uppermost heating plate 15.During operation, one end of the T-tube 2 is connected to the raw material tank for preparing fish oil, and the other end is connected to a storage box containing alkali solution. The mixing pump 1 operates, causing the oil and alkali solution inside the raw material tank to mix simultaneously along the T-tube 2. This neutralizes the acid in the oil. Since the solvent for the alkali solution is water, and the alkali content in the alkali solution is greater than the acid content in the oil, the neutralized oil and water are alkaline. The neutralized oil and water then enter the tubular centrifuge 3 through the first inlet pipe 4 for centrifugal separation. The separated oil enters the washing tank 6 through the outlet pipe 5 for washing. Washing dissolves any alkali residue in the oil. After washing, the first valve 18 is opened, and the water pump 10 operates. The oil and water inside the washing tank 6 enter the evaporator 8 through the second inlet pipe 9. At this time, the heating plate 15 and the high-temperature oil pump 16 work, allowing the oil and water carrying alkali inside the evaporator 8 to enter the high-temperature oil pump 16 through the third inlet pipe 17, and then enter the evaporator 8 through the second drain pipe 11. The oil and water carrying alkali circulate into the evaporator 8 in sequence, keeping the oil and water carrying alkali in a continuous flow state. Each time the oil and water carrying alkali enter the evaporator 8, they will come into close contact with the first guide plate 12 and the second guide plate 13. During this process, the high temperature can make the water carrying alkali evaporate rapidly, thereby removing the remaining alkali in the oil and completing the alkali refining operation of crude fish oil.

[0022] This utility model provides a pipeline-type crude fish oil alkali refining device. Compared with the prior art, the device, through the cooperation of a high-temperature resistant oil pump 16, a third inlet pipe 17, a second outlet pipe 11, a heating plate 15, a first guide plate 12, and a second guide plate 13, can control the circulation of oil and alkali-carrying water into the evaporator 8, keeping the oil and alkali-carrying water in a continuous flow state. Each time the oil and alkali-carrying water enter the evaporator 8, they come into close contact with the first guide plate 12 and the second guide plate 13. During this process, the oil and alkali-carrying water can be dispersed, thereby increasing their surface area and accelerating the evaporation rate of the alkali-carrying water, ultimately improving the alkali refining efficiency of the crude fish oil.

[0023] In another embodiment of this utility model, please refer to Figure 3 A motor 19 is fixedly connected to the upper end of the washing tank 6, and a stirring rod 20 is rotatably connected inside the washing tank 6. The output shaft of the motor 19 is fixedly connected to the stirring rod 20. When the motor 19 is working, the output shaft of the motor 19 drives the stirring rod 20 to rotate. As the stirring rod 20 rotates, the water and oil inside the washing tank 6 can be fully mixed and washed, allowing the alkali in the oil to dissolve into the water, thereby improving the washing effect of the fish oil.

[0024] In another embodiment of this utility model, please refer to Figures 1 to 3A feeding pipe 7 is fixedly connected to the upper end of the washing tank 6, and the feeding pipe 7 is interconnected with the washing tank 6. During operation, clean water can be conveniently injected into the washing tank 6 through the feeding pipe 7.

[0025] In another embodiment of this utility model, see Figure 3 Both the first guide plate 12 and the second guide plate 13 are conical. The first guide plate 12 gradually slopes downward from the middle outward, and the second guide plate 13 gradually slopes downward from the outside outward. During operation, the first guide plate 12 and the second guide plate 13 can guide and disperse the oil and alkaline water, thereby increasing the surface area of ​​the oil and alkaline-containing water. At this time, under the heating effect of the heating plate 15, the evaporation rate of water in the evaporator 8 can be accelerated.

[0026] In another embodiment of this utility model, please refer to Figure 2 and Figure 3 The evaporator 8 has a vent 21 on its upper surface. During operation, excess steam inside the evaporator 8 can be discharged through the vent 21 to prevent excessive pressure inside the evaporator 8.

[0027] In another embodiment of this utility model, please refer to Figure 1 A first drain pipe and a second valve are fixedly connected to the circumferential surface of the front side of the evaporator 8, and the second valve is fixedly connected to the first drain pipe. The first drain pipe is located at the lower end of the first guide plate 12. During operation, after the crude fish oil is alkali-refined, the second valve is opened, and the oil can be discharged through the first drain pipe.
