Description

Technical Field

[0001] The utility model relates to the technical field of o-chlorobenzonitrile production, in particular to a metering device for o-chlorobenzonitrile production proportioning. Background Art

[0002] o-Chlorobenzonitrile is an organic synthesis intermediate, mainly used in the synthesis of dye intermediate 2-cyano-4-nitroaniline, and in the pharmaceutical industry for the synthesis of new antimalarial drugs such as nitroquine. When producing o-chlorobenzonitrile, o-chlorobenzonitrile needs to be proportioned, so a metering device for o-chlorobenzonitrile production proportioning is needed.

[0003] Existing metering devices for o-chlorobenzonitrile production proportioning, for example, a metering device for o-chlorobenzonitrile production proportioning disclosed in Chinese patent application CN219072823U, records: by setting a fixed frame, the fixed frame is set on one side of the weighing device, when the weighing of the batching barrel 1 is completed, the o-aminobenzonitrile inside the batching barrel 1 is taken out, and the batching barrel 2 is placed on the load-bearing block, and the batching barrel 1 is inverted, and the lower end of the batching barrel 1 is clamped inside the circular groove opened at the upper end of the fixing ring, and two groups of rubber rings are arranged inside the circular groove, so that the lower end of the batching barrel 1 can be clamped, so that the batching barrel 1 is fixed to the upper end of the fixing ring, and the motor is started at this time, so that the motor drives the rotating rod and the connecting rod to rotate, and the outer part of the sponge ball contacts the inner wall of the batching barrel 1, so that when the sponge ball rotates, the o-aminobenzonitrile crystal powder attached to the inner wall of the batching barrel can be cleaned.

[0004] When the above-mentioned o-chlorobenzonitrile production proportioning metering device is in use, the o-chlorobenzonitrile crystal powder in the dispensing barrel is cleaned by a sponge ball driven by a motor. The sponge ball will adsorb o-chlorobenzonitrile during the cleaning process. The sponge ball after cleaning cannot be replaced and cleaned, and is not properly handled. After being used for a period of time, it chemically reacts with certain components in the sponge, which not only affects the cleaning effect, but also produces harmful substances or gases, causing the sponge ball to become a secondary pollution source. Moreover, the sponge ball cannot completely adsorb o-chlorobenzonitrile, and the o-aminobenzonitrile crystal powder falls and remains on the bottom surface of the dispensing barrel, especially in irregular or difficult-to-reach areas, resulting in incomplete cleaning of the dispensing barrel, affecting the quality of the next metering.
