Description

Technical Field

[0001] This utility model relates to the field of isobutane preparation technology, and more specifically, to an isobutane feed cooling device. Background Technology

[0002] Isobutane is a colorless, flammable gas at room temperature and pressure. It is slightly soluble in water but soluble in ethanol, diethyl ether, etc. It is mainly found in natural gas, refinery gas, and cracked gas. It can be obtained through physical separation, or it can be produced by isomerization of n-butane. However, isobutane requires cooling during the feeding process, and prolonged use of coolant can lead to a decrease in cooling efficiency, affecting product quality.

[0003] According to patent publication number CN212840682U, an isobutane feeding and cooling device is disclosed, including a tank body. A feed pipe is provided on one side of the tank body, and a spiral tube is provided inside the wall of the feed pipe. Coolant is provided inside the spiral tube, and a first circulation pipe is provided at both ends of the spiral tube. This structure can enhance the cooling effect of the coolant by compressing the coolant evaporated in the spiral tube with a compressor, thereby improving the product quality.

[0004] However, in actual use, such as when isobutane is being cooled, the condenser tube is usually fixed and the cooling effect is achieved only by the contact between isobutane and the condenser tube. This results in insufficient contact area and limited cooling effect. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] As attached Figure 1-5 The isobutane feed cooling device shown includes a casing 1, a feed pipe 2 at the top of the casing 1, a feed valve 3 connected to the outside of the feed pipe 2, rotating frames 4 fixed on both sides of the inner wall of the casing 1, a cooling assembly between the rotating frames 4, a discharge pump 5 on one side of the casing 1, a discharge pipe 6 at the output end of the discharge pump 5, a water outlet valve 7 at the bottom of the casing 1, a storage tank 8 at the bottom of the water outlet valve 7, a reflux assembly on one side of the storage tank 8, and a support frame 9 fixed at the bottom of the casing 1.

[0030] In some embodiments, according to Figure 2 , 3As shown, the cooling assembly includes a through shaft 10 rotatably connected to the axes of two rotating frames 4. One end of the through shaft 10 passes through the rotating frame 4 and the chassis 1 and extends to the outside of the chassis 1. The other end of the through shaft 10 is provided with a water flow shell 11. A plurality of curved condenser tubes 12 are provided on one side of the water flow shell 11. The through shaft 10, the water flow shell 11 and the plurality of curved condenser tubes 12 are connected internally to facilitate the circulation of coolant for cooling. A driven gear 13 is fixedly provided on the outside of the through shaft 10. A transmission gear 17 meshes with the driven gear 13. A bracket 14 is provided on one side of the transmission gear 17. A stepper motor 15 is fixedly provided on one side of the bracket 14. The bracket 14 is fixedly connected to the side wall of the chassis 1. When the stepper motor 15 rotates, the plurality of curved condenser tubes 12 inside the chassis 1 rotate through the gear transmission.

[0031] In some embodiments, according to Figure 2 , 3 As shown, a rotating shaft 16 is fixedly mounted on the output end of the stepper motor 15. The rotating shaft 16 passes through the bracket 14 and extends to the other side of the bracket 14. The rotating shaft 16 is rotatably connected to the housing 1 and fixedly connected to the transmission gear 17. A liquid outlet pipe 18 is provided through the end of the through shaft 10, and a condenser 20 is provided at one end of the liquid outlet pipe 18. A circulation pump 19 is provided at one end of the other through shaft 10, and an extraction pipe 21 is provided at the output end of the circulation pump 19. The extraction pipe 21 is connected to the condenser 20. The circulation pump 19 enables the coolant in the condenser 20 to return to the condenser 20 through the curved condenser pipe 12 to form a loop, thereby cooling the isobutane.

[0032] In some embodiments, according to Figure 4 , 5 As shown, the reflux assembly includes a water pump 22 that is connected to one side of the storage tank 8. The output end of the water pump 22 and the other side of the storage tank 8 are both provided with reflux pipes 23. The water pump 22 can pump the condensate in the storage tank 8 into the flow pipe 25 to cool the chassis. Through the connection between the horizontal pipe 24 and the reflux pipe 23, the condensate can be refluxed.

[0033] In some embodiments, according to Figure 1 As shown, a horizontal pipe 24 is provided through one end of the return pipe 23, and the horizontal pipe 24 is fixedly connected to the support frame 9.

[0034] In some embodiments, according to Figure 4 , 5 As shown, a plurality of flow pipes 25 are provided through one side of the horizontal pipe 24. The plurality of flow pipes 25 all penetrate the chassis 1 and extend to the inside of the chassis 1. The condensate in the flow pipes 25 can cool the inside of the chassis 1 to a certain extent.

[0035] The working principle of this utility model is as follows: (refer to the appendix of the instruction manual) Figure 1-5As shown, firstly, the feed valve 3 is opened to allow isobutane to enter the housing 1 through the feed pipe 2. Then, the stepper motor 15 is started to drive the rotating shaft 16 to rotate the transmission gear 17. The transmission gear 17 then drives the driven gear 13 to rotate, and the driven gear 13 then drives the through shaft 10 to rotate, thereby driving the water flow shell 11 and multiple curved condenser tubes 12 to rotate as a whole, so that the curved condenser tubes 12 can have more sufficient contact with the isobutane in the housing 1.

[0036] At the same time, the circulation pump 19 is started to draw coolant from the condenser 20 to the extraction pipe 21. The coolant enters the through shaft 10 through the circulation pump 19, then through the water flow shell 11, and finally enters the curved condenser tube 12 to cool the isobutane. The coolant in the curved condenser tube 12 then returns to the condenser 20 through the liquid outlet pipe 18, thus circulating and cooling the coolant.

[0037] The condensate generated during the cooling of isobutane will fall to the bottom of the chassis 1 and enter the storage tank 8 through the outlet valve 7. Then, the water pump 22 will be started to pump the condensate in the storage tank 8 to the return pipe 23, enter the horizontal pipe 24, and then enter the flow pipe 25, thereby cooling the inside of the chassis 1 to a certain extent.

[0038] After cooling, the isobutane enters the discharge pipe 6 from the discharge pump 5 and is then discharged, thus proceeding to the next process for further treatment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
