Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a 1-naphthylamine-4-sulfonic acid sodium anti-sticking feeding structure. Background Art

[0002] 1-naphthylamine-4-sodium sulfonate (common name: 4-amino-1-naphthylamine sodium sulfonate, abbreviated as 1,4-sodium acid) is an important azo pigment intermediate, widely used in the synthesis of direct dyes and reactive dyes, and 1,4-sodium acid is also one of the antidotes for nitrites and iodine poisoning; in recent years, it has been found that both the amino group and the sulfonic acid group of 1,4-sodium acid can be well coordinated with the power supply atom, so 1,4-sodium acid can be used as both the donor and the acceptor of hydrogen bonds, making 1,4-sodium acid widely used in complexing with various metals (such as Fe, Zn, Cd, Ni etc.), and is used in the synthesis and clinical research of toxic chemical leakage monitoring equipment, optical devices, and gas absorption materials; 1,4-sodium acid can also be used in fields such as thermal switches, optical switches and information storage component materials, DNA structure probes, and DNA molecular optical switches. In the laboratory, 1-naphthylamine-4-sodium sulfonate is often provided in the form of 1-naphthylamine-4-sodium sulfonate tetrahydrate.

[0003] However, the existing feeding device lacks a corresponding cleaning mechanism, which requires the user to use additional cleaning tools to clean the feeding device, making it troublesome, time-consuming and labor-intensive for the user to clean the feeding device.

[0004] Authorization announcement number CN 212524029U discloses a sodium 1-naphthylamine-4-sulfonate anti-sticking feeding device. Material is fed from a feed hopper and falls onto a stirring paddle through a guide plate. The drive motor is then powered on, causing a rotating rod to rotate, thereby driving a scraper to rotate closely against the inner wall of the feeding hopper via a transmission rod. The scraper then scrapes away any remaining material on the inner wall of the feeding hopper, which is then discharged from a discharge hopper. The feeding device can also be cleaned, making it easier for users to clean the device, saving time and effort.

[0005] However, the above-mentioned anti-sticking feeding device was found to have defects during actual use; the feeding bin could not feed materials at a uniform speed, and the scraper could not clean the lower part of the feeding bin, and sticky materials still remained on the inner wall of the feeding bin, and the scraping was not thorough; at the same time, the height of the anti-sticking feeding device could not be adjusted, and the feeding was restricted, which reduced its practicality.
