[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an efficient aluminum-plastic cracking and recovery device, comprising a connecting pipe;

[0007] The external thread of the connecting pipe is connected to a cold water cover, and circulating water pipes are connected through both sides of the cold water cover.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the high-efficiency aluminum-plastic cracking and recovery device conducts cold water to the cold water cover through the spiral tube, so that after the cold water temperature rises, the cold water is transported away to recover heat, and condenses in stages through the pre-cooling tube, the spiral tube and the ball bin, which can effectively condense and conveniently use the drain port to recover the condensed liquid. The specific contents are as follows:

[0016] 1. The device can be installed at the gas outlet of the cracking device through a threaded pipe. At this time, the hot air flow will enter the connecting pipe through the threaded pipe and the guide pipe. At this time, the cold air in the circulating water pipe will be initially cooled down by the cold water in the pre-cooling pipe and the coil, and a small part of the condensed gas will flow to the drain port and be blocked by the closing plug. Then the initially cooled gas will enter the ball bin through the spiral pipe.

After the temperature of the cold water rises, the heat will be recovered by transporting the cold water away. As the pressure inside the connecting pipe rises, the closing plug will eventually move to the drain port. At this time, the liquid on the top of the guide pipe will flow out through the drain port, which is convenient and stable for recovery.

[0017] 2. When the air pressure pushes the closing plug away from the drain port and allows the liquid to leave through the drain port, the air pressure in the connecting pipe drops, causing the spring to push the closing plug again to block the drain port, which can prevent the liquid from flowing back from the spiral tube and collect the liquid condensed during pre-cooling.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4, the utility model provides a technical solution: an efficient aluminum-plastic cracking and recovery device, comprising a connecting pipe 1;

[0025] The external thread of the connecting pipe 1 is connected to a cold water hood 3, and circulating water pipes 10 are penetrated and connected on both sides of the cold water hood 3. A water pump is installed on the outside of the circulating water pipe 10, and the interior of the cold water hood 3 is filled with cold water. The top surface of the connecting pipe 1 is fixedly connected to a spiral tube 6, and the top end of the spiral tube 6 penetrates the cold water hood 3 and is fixedly connected to a ball bin 7, and the bottom end of the spiral tube 6 extends into the interior of the connecting pipe 1; the water pump can pump away the cold water with increased temperature in the circulating water pipe 10, so that heat can be recovered.

[0026] Among them, a guide tube 4 is fixedly connected to the lower part of the interior of the connecting tube 1, and a drain port 17 opened at the bottom of the connecting tube 1 is provided on the upper side of the guide tube 4, and a closing plug 16 is provided in the drain port 17; the closing plug 16 is fully embedded in the drain port 17, so that when the closing plug 16 is not separated from the drain port 17, the liquid inside the connecting tube 1 cannot pass through the drain port 17.

[0027] The side of the ball bin 7 is fixedly connected to the spiral tube 6, the bottom of the ball bin 7 is fixedly connected to a first recovery tube 8 which is arranged obliquely, an air pressure valve 9 is installed on the first recovery tube 8, and the bottom of the connecting tube 1 is fixedly connected to a threaded tube 2; the air pressure valve 9 can detect the air pressure in the ball bin 7 to achieve stable pressure relief and drainage.

[0028] The top of the guide tube 4 is fixedly connected with a deceleration cover 5. A plurality of windows are provided around the top of the guide tube 4. The deceleration cover 5 is designed to be in an umbrella-like shape. The deceleration cover 5 can reduce the gas flow rate and assist the initial condensation of the gas.

[0029] A precooling pipe 11 is fixedly connected to the middle of the connecting pipe 1, and both ends of the precooling pipe 11 pass through the middle of the connecting pipe 1. A coil 12 is fixedly connected to the bottom end of the precooling pipe 11. The coil 12 is arranged in a ring shape and is arranged on the outside of the guide pipe 4. The cold water filled in the coil 12 and the precooling pipe 11 is connected to the cold water in the cold water hood 3, so they can be drawn out together.

[0030] A second recovery tube 13 fixedly connected to the connecting tube 1 is provided outside the discharge port 17. The second recovery tube 13 is tilted. A movable plate 15 is slidably connected inside the second recovery tube 13. The movable plate 15 is fixedly connected to the closing plug 16. Both the first recovery tube 8 and the second recovery tube 13 can be connected to an external collection dish.

[0031] The liquid discharge port 17 is set to be in an inclined shape, and one end of the closing plug 16 is fixedly connected with a rubber plug; the rubber plug can effectively increase the sealing performance of the closing plug 16; the inclined liquid discharge port 17 facilitates the outflow of liquid.

[0032] A protrusion 18 is fixedly connected to the inside of the second recovery pipe 13, and a spring 19 is fixedly connected to one side of the protrusion 18. The other end of the spring 19 is fixedly connected to the movable plate 15. A movable groove 14 is also opened inside the second recovery pipe 13, and the movable groove 14 is slidably connected to the movable plate 15; the air pressure in the connecting pipe 1 pushes the closing plug 16, so that the pressure required to move the spring 19 is greater than the pressure to push the liquid out of the spiral tube 6. Therefore, when it is necessary to discharge the condensed liquid on the surface of the guide tube 4, the air pressure valve 9 must be closed.

[0033] Working principle: Before using this high-efficiency aluminum-plastic cracking and recovery device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 4 As shown, the device can be installed at the gas outlet of the cracking device through the threaded tube 2. At this time, the hot air flow will enter the connecting pipe 1 through the threaded tube 2 and the guide pipe 4. At this time, the cold air in the circulating water pipe 10 will be initially cooled by the cold water in the pre-cooling pipe 11 and the coil 12, and a small amount of condensed water will flow to the drain port 17 and be blocked by the closing plug 16. Then, the initially cooled gas will enter the ball bin 7 through the spiral tube 6. In this process, the high-temperature gas will be cooled again, and the heat will be transferred to the cold water inside the cold water cover 3 through the spiral tube 6. After the temperature of the cold water rises, the heat is recovered by transporting the cold water away. As the pressure inside the connecting pipe 1 rises, the closing plug 16 will eventually move the drain port 17. At this time, the liquid on the top surface of the guide pipe 4 will flow out through the drain port 17, which is convenient for stable recovery.

[0034] When the air flow rate is relatively fast, the air pressure valve 9 is closed to allow the condensed liquid to accumulate in the ball bin 7. When the pressure is relatively high, the air pressure valve 9 is opened to release the pressure while using the first recovery pipe 8 to effectively recover the liquid condensed in the ball bin 7, and to avoid insufficient condensation caused by the rapid airflow.

[0035] When the air flow is slow, the air pressure valve 9 is directly opened, and the condensed liquid forms a liquid column in the spiral tube 6, which is then slowly pushed out of the spiral tube 6 by the air pressure and enters the ball bin 7, and finally recovered by the first recovery pipe 8;

[0036] When the air pressure pushes the closing plug 16 away from the liquid discharge port 17 and allows the liquid to leave through the liquid discharge port 17 , the air pressure in the connecting pipe 1 decreases, so that the spring 19 pushes the closing plug 16 to block the liquid discharge port 17 again.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
