A ring conveyor 10 is installed outside the compressor 04. Multiple dry ice storage tanks 11 are connected to the inside of the ring conveyor 10. The dry ice storage tanks 11 are arranged in a ring... The conveyor 10 slides inside, the dry ice storage tank 11 has a feed pipe 17 at the top, the dry ice machine 01 has an outlet pipe 05 at the bottom, and the condenser tank 02 has an inlet pipe 18 at the top. One end of the inlet pipe 18 is connected to the outlet pipe 05. A condenser tank 02 is installed between the dry ice machine 01 and the compressor 04, so that carbon dioxide waste gas is first converted into carbon dioxide liquid when it is converted into dry ice (carbon dioxide solid). This avoids the direct conversion of carbon dioxide waste gas into dry ice (carbon dioxide solid), avoids excessive consumption of the compressor 04, extends the service life of the compressor 04, and improves the conversion rate of carbon dioxide waste gas.

[0017] Example 2:

[0018] The condenser tank 02 of this utility model has a condensate inlet pipe 06 on the outside, one end of which is connected to the outlet on the outside of the cold storage tank 03. The condenser tank 02 has a condensate outlet pipe 07 at the bottom, one end of which is connected to the inlet of the cold storage tank 03. The bottom of the condenser tank 02 has an outlet pipe 08. The compressor 04 has an inlet pipe 19 on one side and a discharge pipe 09 on the other side. One end of the outlet pipe 08 passes through the second support table 14 and connects to the inlet pipe 19. One end of the discharge pipe 09 is connected to the inlet pipe 17.

[0019] Example 3:

[0020] This utility model has a condenser chamber 25 inside the condenser tank 02, and a condenser pipe 20 is arranged inside the condenser chamber 25. The top end of the condenser pipe 20 passes through the condenser tank 02 and connects to the air inlet pipe 18, and the bottom part of the condenser pipe 20 passes through the condenser tank 02 and connects to the liquid outlet pipe 08. The annular conveyor 10 has a conveyor belt 21 inside, and the conveyor belt 21 slides inside the annular conveyor 10. The annular conveyor 10 is connected to a switch door 12 on the outside. One end of the switch door 12 has an auxiliary connecting ear 23. The annular conveyor 10 has two positioning connecting ears 22 on the outside, which are symmetrically arranged. The auxiliary connecting ears 23 are connected to the inside of the positioning connecting ears 22 through a rotating shaft. The auxiliary connecting ears 23 rotate on the rotating shaft. The inside of the switch door 12 has a positioning protrusion. The outer side of the annular conveyor 10 has a bucket changing door 13, which is adapted to the positioning protrusion 24.

[0021] Example 4:

[0022] Installation Steps: During use, the carbon dioxide exhaust gas discharged from the dry ice machine 01 enters the condenser tube 20 through the inlet pipe 18. Simultaneously, the coolant inside the cooling tank 03 enters the condensing chamber 25 through the condensate inlet pipe 06. This pressurizes and cools the carbon dioxide exhaust gas inside the condenser tube 20, transforming it into liquid carbon dioxide. The liquid carbon dioxide then enters the compressor 04 through the outlet pipe 08. The threaded design of the condenser tube 20 ensures that the carbon dioxide exhaust gas inside is fully cooled by the condensate, allowing for better condensation into liquid carbon dioxide. After being pressurized and cooled by the compressor 04, dry ice (solid carbon dioxide) is formed. The dry ice then flows through the discharge pipe 09 and the inlet pipe... The material pipe 17 enters the dry ice storage tank 11 for storage. A condenser tank 02 is installed between the dry ice machine 01 and the compressor 04, so that the carbon dioxide waste gas is first converted into liquid carbon dioxide when it is converted into dry ice (solid carbon dioxide). This avoids the direct conversion of carbon dioxide waste gas into dry ice (solid carbon dioxide), avoids excessive consumption of the compressor 04, extends the service life of the compressor 04, and improves the conversion rate of carbon dioxide waste gas. After being filled, the dry ice storage tank 11 is moved to the tank changing door 13 by the conveyor belt 21. Then, the switch door 12 can be opened to remove the dry ice storage tank 11. The conveyor belt 21 drives the dry ice storage tank 11 to move within the ring conveyor 10, which facilitates the replacement of the dry ice storage tank 11. The operation is simple, time-saving and labor-saving.
