[0003] In traditional devolatilization equipment, materials often enter the reactor or devolatilization chamber directly from a central point. This design may cause materials to accumulate at a certain point, resulting in unstable heating and affecting subsequent processing efficiency. Utility Model Content

[0008] In some embodiments, the openings on the different partitions are staggered.

[0009] In some embodiments, the baffle divides the partition holes into multiple regions, and the number of partition holes in the divided regions gradually increases radially from the inside to the outside.

[0010] In some embodiments, the upper end of the feed cylinder is provided with a cover, and a feed pipe is provided on the cover, the feed pipe being positioned corresponding to the center of the partition.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0024] This application provides a material distributor for a devolatilization device, which solves the technical problem of uneven material distribution in the prior art.

[0025] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0026] Example 1

[0027] like Figures 1-3 As shown, this application provides a material distributor for a devolatilization device, comprising: a feed cylinder 1 and a partition 2, wherein the height of the partition 2 gradually decreases from the center outwards, the partition 2 is fixedly disposed on the inner wall of the feed cylinder 1, and a plurality of partition holes 3 are provided on the partition 2 radiating outwards; the feed cylinder 1 and the partition 2 are circular in shape.

[0028] The material falls to the center of the partition 2 and then diffuses outward. The material diffusion process is distributed through the partition holes 3, making the material distribution more uniform.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] Preferably, the partition 2 is provided with multiple baffles 4, the baffles 4 are in a ring shape and are concentric with the partition 2, the shape formed by the baffles 4 is the same as the shape of the partition 2, each baffle 4 is provided with at least one opening 5, and the openings 5 ​​on different partitions 2 are staggered.

[0031] In this embodiment, the baffle 4 is configured as two baffles, which divide the partition 2 into three areas. Each baffle 4 has two openings 5 ​​facing each other.

[0032] The material falls from above the center of the partition 2, flows on the partition 2 or flows out through the partition hole 3. The partition 2 slows down the flow rate of the material flowing on the partition 2, so that the material can flow out of the partition hole 3 evenly. The material can also pass through the opening to avoid material residue at the baffle.

[0033] Furthermore, the baffle divides the partition hole 3 into multiple regions. The number of partition holes 3 in the divided regions gradually increases radially from the inside to the outside. The material flows on the inclined surface of the baffle 2. Since the material flow distance is short in the inner region, by setting the number of partition holes 3 in different regions to gradually increase from the inside to the outside, the material can be discharged radially evenly at the beginning and end of feeding.

[0034] Preferred, such as Figure 4 As shown, a cover 6 is provided at the upper end of the feed cylinder 1, and a feed pipe 7 is provided on the cover 6. The feed pipe 7 is provided at the center position of the partition 2, and the partition 2 is located in the upper half of the feed cylinder 1.

[0035] The material falls through the feed pipe 7 to the middle of the partition 2, causing the material to spread in all directions. The material spreads in the narrow space between the partition 2 and the cover 6, allowing the material to quickly fill the partition 2. Then the material can fall evenly through the partition hole 3, making the heating of the material more stable.

[0036] Example 2

[0037] The feed cylinder 1 and the partition 2 are set to be square in shape. The square partition is made up of four triangular plates spliced ​​together, so that the partition is inclined downward from the center to the outside. The dividing holes 3 are arranged to spread outward on the square partition. The shape of the baffle 4 is the same as that of the partition.

[0038] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
