Specific implementation manners

[0023] 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.

[0024] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a multi-stage packed decompression tower for heat transfer oil production, including a base 1, one side of the top of the base 1 is provided with a decompression tower body 2, one side of the decompression tower body 2 is communicated with an oil discharge pipe 3, and the side of the oil discharge pipe 3 away from the decompression tower body 2 is communicated with a filtering assembly for filtering the oil body; the filtering assembly includes a first connecting pipe 4, one end of the first connecting pipe 4 is communicated with one end of the oil discharge pipe 3, and the end of the first connecting pipe 4 away from the oil discharge pipe 3 is sleeved with a first housing 5. The oil body discharged after condensation of the decompression tower body 2 is discharged into the first connecting pipe 4 through the oil discharge pipe 3, that is, to the outside of the decompression tower body 2.

[0025] Furthermore, the bottom of the first housing 5 is attached to a second housing 6. The cross-sections of the first housing 5 and the second housing 6 are both trapezoidal. By providing the first housing 5 and the second housing 6 with trapezoidal cross-sections, it is convenient to gather the discharged oil body.

[0026] Specifically, a block 7 is provided at the center inside the second housing 6, and connecting rods 8 connected to the inner wall of the second housing 6 are installed around the block 7. A rubber plate 9 is installed on the top of the block 7, and a filter cartridge 10 is placed on the top of the rubber plate 9. The filter cartridge 10 is arranged in a funnel shape, and the bottom of the first connecting pipe 4 extends into the filter cartridge 10. By providing the rubber plate 9, the block 7 and the connecting rods 8, the filter cartridge 10 can be supported, so that the top of the filter cartridge 10 is closely attached to the inner wall of the first housing 5, thereby preventing the phenomenon that the oil body directly enters the second housing 6 without passing through the filtration of the filter cartridge 10.

[0027] In addition, a sealing gasket is installed on the top of the filter cartridge 10 to improve the tightness and sealing performance between the top of the filter cartridge 10 and the inner wall of the first housing 5.

[0028] In addition, fixing blocks 11 are installed around the outside of the first housing 5 and the second housing 6, and the fixing blocks 11 are connected by bolts. By providing the fixing blocks 11, the first housing 5 and the second housing 6 can be tightly connected.

[0029] Furthermore, a cooling component for cooling the oil body is installed on the other side of the top of the base 1. One end of the filtration component away from the drain pipe 3 is communicated with one side of the cooling component. The cooling component includes a water tank 12, a serpentine pipe 13 is arranged inside the water tank 12, one end of the serpentine pipe 13 extends outside the water tank 12, and the other end of the serpentine pipe 13 extends outside the water tank 12 and is communicated with a second connecting pipe 14. The end of the second connecting pipe 14 away from the serpentine pipe 13 is communicated with the bottom of the second housing 6.

[0030] Among them, the second connecting pipe 14 is made of a high-temperature resistant hose. When the filter cartridge 10 needs to be replaced and cleaned, by removing the bolts, the second housing 6 can then be removed from the bottom of the first housing 5, and then the filter cartridge 10 inside the first housing 5 can be taken out, so as to achieve the purpose of facilitating the replacement and cleaning of the filtration structure outside the vacuum distillation tower body 2, and improving the convenience of the vacuum distillation tower during use.

[0031] It should be noted that: a bracket 15 is installed on the top of the base 1 and above the water tank 12, and a refrigerator 16 is installed on the top of the bracket 15. The refrigerating end of the refrigerator 16 extends into the water tank 12. By refrigerating the water in the water tank 12 by the refrigerator 16, the water can cool the oil body entering the serpentine pipe 13 through the second connecting pipe 14, and the cooled oil body is discharged from the other end of the serpentine pipe 13. This can reduce the influence of high temperature on surrounding objects and instruments, and it is not easy to occur the phenomenon of scalding due to too high oil body temperature.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
