[0023] The embodiments of the present utility model will be described in detail below. Referring to Figures 1 to 3 , the embodiments of the present utility model provide a sieving and degassing device, including a sieving assembly 100, a material pipe 200 and a degassing assembly 300. The sieving assembly 100 is used for sieving materials such as gels to obtain gel particles. The gel particles obtained after sieving enter the degassing assembly 300 through the material pipe 200, and the degassing assembly 300 performs degassing treatment on the gel particles.

[0024] Further, referring to Figure 2 and Figure 3, the sieving assembly 100 includes a first material tank 110, a first piston 120, and a sieve 130. A first material chamber 111 is formed inside the first material tank 110 for holding materials such as gels. An outlet 161 communicating with the first material chamber 111 is formed at the bottom of the first material tank 110. The first piston 120 is movably installed inside the first material chamber 111. The sieve 130 is located between the first piston 120 and the outlet 161. The first piston 120 can move towards the sieve 130 to extrude the materials in the first material chamber 111 through the sieve 130. After the materials such as gels pass through the sieve 130, gel particles are formed and fall into the feed inlet 331. Further, the degassing assembly 300 has a second material chamber 311 and a feed inlet 331 communicating with the second material chamber 311. Two ends of the material pipe 200 are respectively connected to the outlet 161 and the feed inlet 331. After the gel particles fall into the feed inlet 331, they can pass through the material pipe 200 and the outlet 161 and enter the second material chamber 311, and the degassing assembly 300 can perform degassing treatment on the materials.

[0025] The sieving and degassing device uses the first piston 120 to extrude the materials through the sieve 130, so that the materials can be quickly sieved to form gel particles with uniform particles and a relatively small particle size distribution range. And the gel particles passing through the sieve 130 can successively pass through the outlet 161, the material pipe 200, and the feed inlet 331 and enter the second material chamber 311, and the degassing assembly 300 performs degassing treatment on the gel particles. It can realize sieving and degassing simultaneously on one device, which can not only improve production efficiency, but also reduce the loss caused by material transfer and reduce the pollution risk brought by material transfer.

[0026] Further, continue to refer to Figure 2 and Figure 3 , the sieving assembly 100 further includes a first upper cover 140 hermetically connected to the top of the first material tank 110. The first upper cover 140 and the top of the first material tank 110 are tightly connected by a first locking hoop 142 to realize the sealing and covering of the top of the first material tank 110 by the first upper cover 140. A compressed air interface 141 communicating with the first material chamber 111 is formed on the first upper cover 140. The compressed air interface 141 is used to connect compressed air equipment. After the compressed air equipment is started, the first piston 120 will extrude the materials towards the sieve 130 under the action of compressed air, extrude the materials onto the sieve 130, and make the materials pass through the sieve 130 to form gel particles.

[0027] Further, refer to Figure 2 , Figure 4 and Figure 5, the sieving assembly 100 further includes a first lower cover 150 hermetically connected to the bottom of the first material tank 110.

The first lower cover 150 is provided with a cylindrical convex ring 151, and a relief hole 152 is formed in the convex ring 151. The sieve mesh 130 is fixedly connected to the bottom of the convex ring 151 and covers the relief hole 152. The first piston 120 is provided with a protrusion 121. Refer to Figure 2 , the protrusion 121 can extend into the relief hole 152 and press the material against the sieve mesh 130, so that the material passes through the sieve mesh 130 and forms gel particles.

Further, in order to better monitor the vacuum pumping situation in the second material tank 310 to ensure that the gel particles can be degassed while preventing the gel particles from being crushed, the second upper cover 330 is further provided with a pressure gauge mounting port 333 communicating with the second material chamber 311.
