The outer wall of the sieve plate 9 is welded to the inner wall of the storage tank 1, and the sieve plates 9 are evenly distributed in the storage tank 1 at equal distances. A mounting seat 11 is welded to the outer wall of the lower end of the storage tank 1, and a material collection plate 10 is welded to the inner wall of the lower end of the storage tank 1. The material collection plate 10 is distributed in a funnel shape, and the material collection plate 10 is distributed below the sieve plate 9. The mounting seat 11 serves as an installation support component for the storage tank 1 to meet the needs of the user to install the storage tank 1 in the workshop through the mounting seat 11, and provides the needs for the installation of the storage tank 1. At the same time, the material collection plate 10 adopts a funnel design, which can meet the feeding needs of copolymer nylon and reduce the possibility of copolymer nylon accumulation in the storage tank 1.

[0023] Embodiment 2

[0024] On the basis of Example 1, the gas outflow end of the vacuum pump 5 is connected to an air outlet pipe 6, and the air outlet pipe 6 is connected to the workshop pipe. The vacuum pump 5 is designed for vacuuming the storage tank 1. The air in the storage tank 1 is extracted through the vacuum pump 5 to meet the drying requirements of the storage tank 1 and the vacuum drying requirements of the copolymer nylon. A material hopper 2 is welded to the bottom of the lower end of the storage tank 1, and the bottom of the lower end of the hopper 2 is connected to a discharge pipe 3. The outer wall of the discharge pipe 3 is provided with an electromagnetic valve 31 for controlling the opening and closing. The entire discharge pipe 3 serves as a discharge component of the storage tank 1, and its inner wall is controlled by the electromagnetic valve 31 to connect and close, ensuring that no other air is added to the storage tank 1 when the storage tank 1 is vacuumed. The size design of the discharge pipe 3 is convenient for users to access the discharge pipe 3 through the storage equipment to receive materials.

[0025] Embodiment 3

[0026] On the basis of the second embodiment, a vibration motor 7 is mounted on the middle outer wall of the storage tank 1, and the vibration motor 7 knocks the outer wall of the storage tank 1 to prevent the copolymer nylon from gathering on the sieve plate 9. When the vacuum pump 5 is vacuuming, the airflow of the storage tank 1 circulates along the vertical pipe 8, accelerating the water flow rate on the surface of the copolymer nylon to meet the demand for drying the copolymer nylon. At the same time, the copolymer nylon falls onto the sieve plate 9, and the copolymer nylon is blocked by the sieve plate 9 to reduce the falling speed of the copolymer nylon, which can ensure that the copolymer nylon is fully vacuumed and dried, improve the drying degree of the copolymer nylon, and reduce the possibility of repeated drying of the copolymer nylon, thereby improving the efficiency of the entire copolymer nylon drying process and bringing certain economic benefits to the enterprise.

[0027] In actual use, the copolymer nylon particles are pumped into the storage tank 1 through the feed pipe 4. At this time, the user starts the vacuum pump 5. When the vacuum pump 5 is vacuuming, the vibration motor 7 knocks on the inner wall of the storage tank 1, and the copolymer nylon particles are vibrated and fall down along the sieve plate 9 in sequence. At the same time, the air flow of the storage tank 1 circulates along the vertical pipe 8, which accelerates the water flow rate on the surface of the copolymer nylon. At the same time, the copolymer nylon falls onto the sieve plate 9. The copolymer nylon is blocked by the sieve plate 9, which reduces the descending speed of the copolymer nylon, ensuring that the copolymer nylon is fully vacuumed and dried. Subsequently, the copolymer nylon falls onto the collection plate 10, and falls into the hopper 2 along the middle through hole of the collection plate 10. Finally, the discharge pipe 3 is opened through the electromagnetic valve 31, and the copolymer nylon falls into the designated collection equipment for storage and transportation.
