[0002] Existing animal oil refining systems mostly use a pot-type structure, which divides the solid fat and places it into a refining pot for high-temperature refining. However, this type of open refining equipment has technical disadvantages in actual use, mainly reflected in the following: 1. Existing animal refining pots are mostly electrically driven, which has high energy consumption and capacity limitations, and usually do not use large capacity and high power operation; 2. Existing refining pots are heated by electric heating tubes or gas, and their heating points are fixed. When heated, it is easy to cause the fat inside to stick to the pot body and gelatinize, resulting in burnt areas inside the refining pot, affecting the quality of the oil; 3.

[0031] The present invention is further described below through an implementation method. As shown in the accompanying drawings, the following description is only an exemplary explanation of the energy-saving animal oil refining system. Those skilled in the art can make further structural improvements based on the following explanation. The scope of protection of this patent shall be based on the scope recorded in the claims.

[0032] Example 1:

[0033] An energy-saving animal oil refining system, such as Figure 1 As shown, in this embodiment, it includes two tanks, namely a primary heating tank 1 and a secondary heating tank 10. The tops of the primary heating tank 1 and the secondary heating tank 10 are both provided with a feed port 13, and the bottoms of the two tanks 11 are provided with a discharge port 16. The feed port 13 and the discharge port 16 are respectively provided on the left and right sides of the tank 11. The purpose of this design is to restrict the fat from flowing within the tank 11 over the longest distance. The bottoms of the two discharge ports 16 are connected by a fat pipe 20, which discharges the refined fat to the outside.

[0034] Both ends of the tank body 11 are provided with extension sections 12 , and the extension sections 12 are provided with observation ports 15 , through which the internal grease state or grease amount of the tank body 11 can be observed.

[0035] The tank body 11 is provided with a support base 3 on both sides of the front and rear, and a horizontal support plate 31 is provided on the support base 3, and a bearing seat 4 is mounted on the support plate 31. The tank body 11 is provided with a stirring heating element 5, such as Figure 5 、8 As shown in Figures 9 and 9, the stirring and heating element 5 includes a hollow shaft 51 that cooperates with a bearing seat. The center of the hollow shaft 51 is a through hole 52. The outer periphery of the hollow shaft 51 is covered with a heating chamber 53. A plurality of heating discs 54 are fixed to the heating chamber 53. The plurality of heating discs 54 are spaced apart on the heating chamber 53 to form a plurality of gaps 55. When the heating discs 54 are fixed to the heating chamber 53, they also penetrate the interior of the heating chamber 53. The heating disc 54 includes a central ring 542 and left and right side plates 541. The central ring 542 and the side plates 541 are welded to form a disc-shaped chamber. With the above structural arrangement, after the hollow shaft 51 is connected to the outside, the heating oil or heating steam enters the heating chamber 53 through the through hole 52 and is then directed into the heating disc 54. The heating disc 54 increases the contact area with the solid fat, thereby improving the heating efficiency. When the stirring and heating element 5 is assembled on the tank body 11, the hollow shaft 51 penetrates the front and rear side walls of the tank body 11 and rotates with the front and rear side walls of the tank body 11 through a sealing slip ring assembly. The front and rear ends of the hollow shaft 51 are respectively fixed to the front and rear bearing seats 4, and at least one end is connected to an external rotation drive device to drive the entire stirring and heating element 5. The heating medium is introduced into the stirring and heating element 5. Through the in-situ rotation of the stirring and heating element 5, the interior of the tank body is heated and stirred at the same time, preventing the solid fat from adhering to the inner wall of the tank body 11 and burning.

[0036] The utility model is provided with an independent inspection port 14 on the top of the tank body 11 , through which personnel can enter and exit the tank body 11 and clean the interior of the tank body.

[0037] The present invention has support legs 19 welded to the bottom of the tank body 11. When installing support legs 19, the tank body 11 is typically tilted, with the side where the discharge port 16 is located being the lower side. Typically, this tilt angle is approximately 5 degrees. After the solid oil is refined, gravity, without external force, allows the oil to naturally flow to the side of the discharge port 16 and be discharged to the outside. Because the present invention breaks the solid oil into chunks less than ten centimeters in length during use, the solid impurities in the liquid oil after refining are relatively small and can be discharged along with the liquid oil.

[0038] The utility model is provided with a heat transfer oil heating part 2 on the outside of the tank body 11 of the primary heating tank 1. The heat transfer oil heating part 2 is arranged in the lower half of the tank body 11. The heat transfer oil heating part 2 covers the bottom and the left and right sides of the tank body 11 as a whole. The heat transfer oil heating part 2 is composed of a plurality of heat transfer cavities 21 connected end to end. The plurality of heat transfer cavities 21 are all arranged in close contact with the tank body 11. Figure 4As shown, the above structure can realize the serpentine movement of the heat transfer oil in the heat transfer oil heating part 2, and can fully and evenly heat the outer wall of the tank body 11. The heat transfer oil inlet 22 and the heat transfer oil outlet 23 are respectively arranged on the head and tail heat transfer chambers 21.

[0039] The primary heating tank 1 is the first tank. When it works, Figure 1 As shown, the hollow shaft 51 of the primary heating tank 1 and the thermal oil heating unit 2 are connected to an external oil supply circulation pump, which includes at least one of the oil supply pump 6 and the oil return pump 17; when the oil supply pump 6 is connected, as shown in FIG. Figure 1 The oil return pump 17 is connected to the thermal oil outlet 23 via return valve I 18, directly connected to the end of the hollow shaft 51 via a pipeline, and connected to the external oil return pipe via return valve II 19, thereby directing the heat exchanged thermal oil back to the external thermal oil supply tank.

[0040] The top of the primary heating tank 1 is connected to a steam vacuum pump 9 via piping, which directs the steam within the primary heating tank 1 to the hollow shaft 51 of the slave heating tank 10 and the steam heating unit 7. During this connection, a main steam valve 91 is installed on the front piping of the steam vacuum pump 9. A central air supply valve 93 is installed on the rear piping of the steam vacuum pump 9, which connects to the hollow shaft 51 at the center of the slave heating tank 10. A peripheral air supply valve 92 is also installed on the rear piping of the steam vacuum pump 9, which connects to the steam heating unit 7. This directs the high-temperature steam generated during the refining process in the primary heating tank 1 to the slave heating tank 10.

[0041] like Figure 1 As shown, the tank body 11 of the slave heating tank 10 is also provided with a stirring heating element 5, and its outer periphery is a steam heating part 7, as shown in FIG. Figure 6 As shown, the steam heating unit 7 covers the lower portion and bottom surface of the tank body 11. Several reinforcement grooves 71 are provided on the peripheral plate of the steam heating unit 7. These reinforcement grooves 71 connect the outer wall of the tank body 11 with the outside without compromising the sealing of the peripheral heating unit. The steam heating unit 7 is provided with a steam inlet 72 and a steam outlet 73. The provision of several reinforcement grooves 71 prevents deformation of the steam heating unit 7 caused by steam overheating, effectively enhancing the overall strength of the peripheral heating unit.

[0042] Furthermore, the same reinforcement principle as that of the steam heating part 7 is adopted. Since the heating plate 54 is a disc-shaped sealed structure, it is very easy to bend and deform when heated, and even cause the weld to crack due to deformation. In order to prevent the occurrence of such deformation problems, Figure 8、 9 As shown, the present invention has a plurality of reinforcement grooves or through reinforcement holes 56 axially processed on the heating plate 54 , and the reinforcement grooves or through reinforcement holes 56 do not destroy the sealing performance of the heating plate.

[0043] At the end of the operation of the above heat recovery system, exhaust gas is still generated. This part of the exhaust gas still contains heat. In order to avoid direct discharge to the outside, the utility model is connected to the exhaust fan 85 through pipelines at the end of the hollow shaft 51 of the slave heating tank 10 and the steam outlet 73. The exhaust fan 85 is connected to the air treatment tower 86. The air treatment tower 86 can be a spray tower, which performs terminal treatment on the steam exhaust to ensure that the discharged air meets the standards.

[0044] When the slave heating tank 10 is operating, a condensate collection port 87 is provided at the bottom of the steam heating unit 7. A pipeline is connected to the condensate collection port 87. This pipeline is connected to the condensate collection pump 8 via a condensate collection valve 83. The condensate collection pump 8 is connected to an external water collection tank 84. The end of the hollow shaft 51 of the slave heating tank 10 is connected to a manifold 81. This manifold 81 is connected to an external water collection tank 84 via a master manifold valve 82 and the manifold pump 8.

[0045] Through the above structural arrangement, the condensed water generated during the secondary heat exchange process is collected in the water collection tank 84 for other uses, thereby realizing the reuse of water resources. Through the above system arrangement, the present invention can transfer the waste heat in the primary heating tank 1 into the slave tank for secondary use, thereby improving refining efficiency and reducing energy loss.
