Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a crystal trap convenient for scraping materials. Background Technique

[0002] Pyromellitic dianhydride, abbreviated as pyromellitic anhydride, is a white or slightly yellowish crystal in its pure form. It will quickly absorb the moisture in the air and hydrolyze into pyromellitic acid when exposed to humid air. It is soluble in organic solvents such as dimethyl sulfoxide, dimethylformamide, and acetone, and insoluble in ether, chloroform, and benzene. It is mainly used as a raw material for polyimide, used to manufacture the curing and matting agent of epoxy resin and the cross-linking agent of polyester resin. In the production process of pyromellitic dianhydride, the raw material mycelium toluene needs to be vaporized, and after an oxidation reaction with air, it needs to pass through a trap to cool and crystallize the mixed gas for collection.

[0003] The patent authorization announcement number CN208426683U discloses a pyromellitic dianhydride crystal trap, including a tank body, the upper surface of the tank body is fixedly connected with an upper cover body, the top of the upper cover body is fixedly inserted with a feed pipe, the bottom end of the feed pipe extends below the upper cover body, the upper surface of the upper cover body is fixedly connected with a pressure gauge, a cooling groove is opened inside the side wall of the tank body, and the top of the left outer wall of the tank body is fixedly inserted with a water inlet pipe. For this pyromellitic dianhydride crystal trap, the lower cover body is disassembled by the fixing rod being clamped in the clamping groove, so that the staff can conveniently collect the crystals in the lower cover body, reducing the waste of time. During the process of moving the lower cover body, the connecting rod is controlled to make the scraper scrape the crystals on the inner wall of the tank body, and there is no need for manual secondary cleaning, reducing the labor intensity of the staff, achieving the effect of convenient crystal collection.

[0004] However, the above technical solution has the following deficiencies: during the crystallization process, the scraper is always in contact with the inner wall of the tank body, and crystals adhere to the scraper and the inner wall of the tank body, resulting in a sticking phenomenon between the scraper and the tank body. When the scraper is used to scrape the crystals attached to the inner wall of the tank body, the scraper is very difficult to move, and the crystal removal effect is poor.
