However, in its production process, due to the complex raw materials and harsh reaction conditions, a large amount of impurities are often produced, which seriously affect the purity and yield of the product. Therefore, a purification device for 3-oxetanone is needed.

[0003] The existing purification device of 3-oxetanone is usually provided with multiple distillation sections through a multi-stage distillation tower, and 3-oxetanone is separated from its impurities by gradual heating and cooling; the condenser is used to condense the distilled 3-oxetanone vapor into liquid; the collection tank is used to collect the condensed 3-oxetanone; and the filtration system is used to further remove solid impurities in the condensate;

[0004] When 3-oxetanone is heated, the impurities separated from the 3-oxetanone will condense and adhere to the inside of the cylinder, making it inconvenient to subsequently clean and remove the impurities. Therefore, we have made improvements to this and proposed a purification device for 3-oxetanone. Utility Model Content

The output end of the second motor 504 is fixedly connected to the first threaded rod 502. When the second motor 504 is working, it drives the first threaded rod 502 at the output end to rotate, which can drive the sliders 503 on the upper and lower end surfaces to move relative to each other.

[0035] As a preferred embodiment, on the basis of the above-mentioned method, further, both side surfaces of the two sliders 503 are rotatably connected with support rods 505, and the other end of the support rod 505 on the same side is rotatably connected with a wiping rod 507, and when the two sliders 503 move relative to each other, the wiping rod 507 can be stretched open by the support rods 505, and both side surfaces of the support rods 505 are provided with limiting grooves 506, and the connection method between the support rods 505 and the limiting grooves 506 is a sliding connection, and the support rods 505 and the sliders 503 can be limited by the limiting grooves 506 to prevent the sliders 503 from rotating with the first threaded rod 502.

The second motor 504 will drive the first threaded rod 502 at the output end to rotate. Since the thread directions at both ends of the first threaded rod 502 are arranged in opposite directions, the sliders 503 on the upper and lower sides can be driven to move relative to each other at the same time. When the slider 503 moves, the wiping rod 507 can be propped to one side by the support rod 505 connected by surface rotation, so that the wiping rod 507 contacts the inner wall of the fixed cylinder 1. When the first motor 401 is started to drive the rotating shaft 402 and the stirring shaft 403 to rotate, the wiping rod 507 can be driven to rotate at the same time to clean the inner wall of the fixed cylinder 1.

[0041] The separated impurities will fall to the bottom of the fixed cylinder 1. Turning the handle 805 will drive the second threaded rod 804 to rotate so that one end of the second threaded rod 804 is not connected to the fixed block 803, making it easy to open the bottom cover 7 and clean the impurities separated from the bottom. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
