[0002] Carbon molecular sieve, a novel adsorbent developed in the 1970s, is an excellent non-polar carbon material. Nitrogen-producing carbon molecular sieves are used to separate nitrogen from air. Using a room-temperature, low-pressure nitrogen production process, they offer advantages over traditional cryogenic, high-pressure nitrogen production processes, including lower investment costs, faster nitrogen production rates, and lower nitrogen costs. Therefore, they are the engineering community's preferred nitrogen-enriching adsorbent for pressure swing adsorption air separation. This nitrogen is widely used in the chemical, oil and gas, electronics, food, coal, pharmaceutical, cable, metal heat treatment, transportation, and storage industries.

[0003] Application number 202320335350.7, which proposes a cooling and conveying device for carbon molecular sieve production: the cooling effect is not good during traditional cooling, there is only a single cooling and cooling device, which cannot simultaneously cool the inside and outside, and when the temperature of the cooled carbon molecular sieve is still too high, it is inconvenient to adjust and lower the temperature of the carbon molecular sieve, which is inconvenient to use.

[0004] However, when the above device is in use, since the material in the tank is in a static state, the cooling rate of the material near the middle tank and the inner tank is different from that of the material in the middle, resulting in the outer blocks cooling slower than the inner ones, which affects the cooling efficiency.
