Description

Technical Field

[0001] This utility model relates to the field of nylon polymerization technology, and in particular to an improved structure of a rotary valve for polymerizing chips. Background Technology

[0002] Nylon polymer chips are mainly produced using liquid caprolactam as raw material, with titanium dioxide, acid, amine, and other auxiliary materials through a two-stage polymerization process. During the production of nylon 6 chips, the chips are stored in a drying tower and then transported to the cooling tower of the next process step via a rotary valve.

[0003] The working principle of a rotary slicing valve can be summarized as follows: Through uniformly rotating blades, material is conveyed quantitatively and continuously from the inlet to the outlet, while simultaneously forming an effective seal between the upstream and downstream sides, preventing airflow exchange. Existing rotary slicing valves require 24-hour operation, which places a significant load on the fixed bearings at both ends. Currently, maintenance of these bearings involves periodically applying grease, but this has limited effectiveness and can lead to overheating during prolonged operation, reducing their lifespan and consequently shortening the overall lifespan of the rotary valve. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an improved structure for a polymer slicing rotary valve, which can improve the service life of the rotary valve, reduce the number of downtime maintenance, and improve the stability and continuity of production.

[0005] This utility model is implemented as follows: This utility model provides an improved structure for a polymer slicing rotary valve, including a rotary valve body. The rotary valve body has bearing brackets at both ends. Each bearing bracket is provided with a first through hole, and the first through hole is connected to a first air pipe connector. The structure also includes an airflow diversion element, which has at least three interfaces, namely a first interface, a second interface, and a third interface. The first interface is connected to the nitrogen pipeline in the workshop, and the second and third interfaces are respectively connected to the first air pipe connector.

[0006] Furthermore, the lower end of the rotary valve body is a discharge port, and a second through hole is provided in the housing at the discharge port. The second through hole is connected to a second air pipe connector. The airflow diversion element is a four-way connector, and the fourth interface of the airflow diversion element is connected to the second air pipe connector.

[0007] The advantages of this invention are as follows: by introducing nitrogen gas into the bearing mounting bracket, the operating temperature of the bearing can be reduced in a timely manner, extending the bearing's service life. Furthermore, the nitrogen gas introduced into the feed inlet can promptly deliver the slices to the next process, preventing slices from accumulating and clogging at the outlet, thus improving feeding efficiency.

[0012] Existing rotary valves for slicing require 24-hour operation, placing a significant load on the fixed bearings at both ends of the valve and affecting its service life. Furthermore, prolonged overload operation increases wear between the rotor and the housing inside the valve, reducing efficiency, causing slice accumulation, and impacting feeding efficiency. Therefore, this invention provides an improved structure for a rotary valve for polymer slicing. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The structure includes a rotary valve body 1, with bearing mounting brackets 11 at both ends. Each bearing mounting bracket 11 has a first through hole, which is connected to a first air pipe connector 2. The structure also includes an airflow diversion element 3, which is located on the side of the rotary valve body 1. The airflow diversion element 3 has at least three interfaces, namely a first interface, a second interface, and a third interface. The first interface is connected to the nitrogen pipeline 5 in the workshop and is used to guide the nitrogen in the nitrogen pipeline 5 to the airflow diversion element 3. The second interface and the third interface are respectively connected to the first air pipe connector 2.

[0013] Specifically, the lower end of the rotary valve body 1 is a discharge port 12, and a second through hole is provided in the housing at the discharge port 12. The second through hole is connected to a second air pipe connector 4. The airflow diversion element 3 is a four-way connector, and the fourth interface of the airflow diversion element 3 is connected to the second air pipe connector 4.

[0014] By introducing nitrogen into the bearing holder 11, the heat generated during bearing operation can be carried away in a timely manner, effectively reducing the bearing's operating temperature and extending its service life, thereby extending the service life of the rotary valve. Furthermore, the nitrogen introduced into the feed port 12 can assist in the conveying of the polymerized chips, ensuring timely delivery of the chips to the next process, preventing chip accumulation and blockage at the discharge port, and improving feeding efficiency.
