[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Referring to Figures 1-4 , an embodiment provided by the present utility model: a feed heat exchanger for solvent oil production, including a liquid storage tank 2 and a housing 4. The liquid storage tank 2 is arranged on the left part of the housing 4. The liquid storage tank 2 is used to store the coolant. The housing 4 provides a space for cooling the solvent oil. The housing 4 is made of stainless steel, which can reduce the erosion and thus extend the service life. An oil outlet pipe 3 and an oil inlet pipe 5 are respectively installed on the outer periphery of the housing 4. The oil outlet pipe 3 and the oil inlet pipe 5 are fixed on the surface of the housing 4. The solvent oil can be added into the interior of the housing 4 through the oil inlet pipe 5 and discharged through the oil outlet pipe 3. A liquid delivery pump 1 is fixedly connected to the top side of the liquid storage tank 2. The liquid delivery pump 1 plays a role in driving the flow of the coolant. Liquid delivery pipes 6 are installed at both the input end and the output end of the liquid delivery pump 1. The bottom end of one of the liquid delivery pipes 6 is arranged at the inner bottom side of the liquid storage tank 2. The other liquid delivery pipe 6 penetrates the housing 4. One end of the other liquid delivery pipe 6 is installed inside the top of the liquid storage tank 2. The liquid delivery pipe 6 plays a role in transporting the coolant. The coolant flowing inside the liquid delivery pipe 6 can absorb the heat of the solvent oil. A plurality of uniformly distributed fixing sleeves 9 are installed on the outer periphery of the other liquid delivery pipe 6. The fixing sleeves 9 are used to install heat conducting fins 10. The fixing sleeves 9 are made of copper and have good heat conducting performance. Heat conducting fins 10 are fixedly connected to the outer periphery of the fixing sleeves 9. The heat conducting fins 10 can absorb the heat of the solvent oil and transfer the heat to the fixing sleeves 9. A plurality of uniformly distributed through holes are formed inside the heat conducting fins 10, which can increase the contact area between the solvent oil and the heat conducting fins 10. Two propellers 12 are arranged inside the housing 4. The solvent oil can drive the propellers 12 to rotate during the flowing process. The rotation of the propellers 12 can block the normal flow of the solvent oil. Two mounting frames 11 are fixedly connected inside the housing 4. The mounting frames 11 are used to mount the propellers 12. A mounting shaft 15 is installed on the left side of the mounting frame 11. The outer periphery of the mounting shaft 15 is installed inside the propellers 12. The mounting shaft 15 plays a role in connecting the propellers 12 and the mounting frames 11. A limiting plate 14 is fixedly connected to the left end of the mounting shaft 15. The limiting plate 14 is arranged inside the propellers 12. The limiting plate 14 slides inside the propellers 12 to prevent the propellers 12 from separating from the mounting shaft 15. A first spring 13 is installed on the left side of the limiting plate 14. The left end of the first spring 13 abuts against the inside of the propellers 12. When the solvent oil impacts the propellers 12, the propellers 12 can squeeze the first spring 13. The contraction of the first spring 13 can absorb the impact of the solvent oil to prevent the solvent oil from damaging the propellers 12.

[0035] Referring to Figure 1 , Figure 2And Figure 5 A cooling component is provided at the rear side of the liquid storage tank 2. The cooling component is used to lower the temperature of the coolant inside the infusion tube 6. The cooling component includes a cooling chamber 7. The cooling chamber 7 is fixedly connected to the rear side of the liquid storage tank 2. The outer periphery of the other infusion tube 6 is arranged inside the cooling chamber 7. The cooling chamber 7 serves to provide space for cooling the coolant. Two fans 16 are installed on the inner side of the top of the cooling chamber 7. The rotation of the fans 16 can drive the external air flow into the cooling chamber 7 and blow towards the other infusion tube 6. A plurality of uniformly distributed heat dissipation holes 17 are formed in the inner parts of the left and right sides of the cooling chamber 7. After the air flow absorbs heat, it can be discharged through the heat dissipation holes 17.

[0036] Refer to Figure 5 、 Figure 6 A filtering component is provided on the inner side of the top of the cooling chamber 7. The filtering component is used to filter impurities in the air flow. The filtering component includes a filter plate 8. The filter plate 8 is arranged inside the cooling chamber 7. The filter plate 8 is arranged on the top of the fan 16. The filter plate 8 is used to filter impurities in the air flow. A plurality of uniformly distributed moving shafts 21 are slidably connected to the inner side of the top of the cooling chamber 7. A plurality of uniformly distributed grooves are formed in the filter plate 8. One end of the moving shaft 21 is slidably connected inside the groove. When one end of the moving shaft 21 is inserted into the groove, the filter plate 8 can be fixed inside the cooling chamber 7. A push plate 19 is installed on the outer periphery of the moving shaft 21. A second spring 20 is sleeved on the outer periphery of the moving shaft 21. One end of the second spring 20 is fixedly connected to one side of the push plate 19. The other end of the second spring 20 is fixedly connected to the inside of the cooling chamber 7. The push plate 19 is used to connect the moving shaft 21 and the second spring 20 to each other. The second spring 20 can push the moving shaft 21 to move. A moving rod 22 is installed on the outer periphery of the moving shaft 21. Pushing the moving rod 22 to move can pull one end of the moving shaft 21 out of the groove. A connecting plate 18 is fixedly connected to the opposite sides of two adjacent moving rods 22. The connecting plate 18 serves to connect two adjacent moving rods 22 to each other.

[0037] Working principle: When using this device, high-temperature solvent oil is added into the shell 4 through the oil inlet pipe 5 and the infusion pump 1 is started at the same time. The infusion pump 1 drives the coolant to enter the shell 4 through the infusion tube 6. After the high-temperature solvent oil enters the shell 4 and contacts the infusion tube 6, the coolant inside the infusion tube 6 can absorb the high temperature inside the high-temperature solvent oil. A plurality of heat conducting sheets 10 and a plurality of fixed sleeves 9 increase the contact area between the infusion tube 6 and the solvent oil, thereby improving the efficiency of the coolant absorbing heat. During the flow of the solvent oil, the two propellers 12 can be driven to rotate. The rotation of the two propellers 12 can hinder the normal flow of the solvent oil and increase the residence time of the solvent oil inside the shell 4 so that the coolant can fully absorb the heat in the solvent oil. The cooled solvent oil can be discharged through the oil outlet pipe 3.

[0038] After absorbing heat, the coolant enters the inside of the cooling chamber 7, and then two fans 16 can be started. The rotation of the fans 16 can drive the air flow into the inside of the cooling chamber 7 and blow towards the inside of the infusion tube 6 to cool the coolant, thereby maintaining the cooling effect of the coolant. The filter plate 8 can filter the dust in the air flow into the inside of the cooling chamber 7 to prevent the dust from adhering to the surface of the infusion tube 6, resulting in a low air flow cooling efficiency. The dust adheres to the surface of the filter plate 8. When the filter plate 8 needs to be cleaned, two connecting plates 18 can be pushed to move. The two connecting plates 18 drive a plurality of moving shafts 21 to move through a plurality of moving rods 22, so that one end of the plurality of moving shafts 21 is pulled out from the inside of the filter plate 8. After that, the filter plate 8 can be taken out of the inside of the cooling chamber 7 for cleaning.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
