specific Embodiment approach

[0034] As a specific embodiment of the present invention, one end of the No. 1 rod 25 close to the inner wall of the tower body 1 is provided with a spherical groove 251, and a No. 1 ball 252 is rollingly connected in the spherical groove 251;

[0035] When in use, a spherical groove 251 is provided at one end of the No. 1 rod 25 close to the inner wall of the tower body 1, and a No. 1 ball 252 is connected by rolling in the spherical groove 251. When the motor 2 rotates, the motor 2 drives the output shaft 21 to carry out the operation. Rotation, the output shaft 21 drives the scraper 22 to rotate, when the scraper 22 rotates, the No. 1 rod 25 in the No. 1 slot 23 inside the scraper 22 is in contact with the inner wall of the tower body 1 and the side of the overflow weir 121 under the action of the spring 24 , and the end of the scraper 22 away from the output shaft 21 of the motor 2 produces friction with the inner wall of the tower body 1. By opening a spherical groove 251 ...

Embodiment approach

[0036] As a specific embodiment of the present invention, the side of the overflow weir 121 away from the inner wall of the tower body 1 is evenly provided with arc-shaped blocks 14 , and the arc-shaped blocks 14 are located at both ends of the overflow weir 121 . The convex surface of the shape block 14 is fixedly connected with the inner wall of the tower body 1;

[0037] When in use, the curved blocks 14 are evenly arranged on one side of the overflow weir 121 away from the inner wall of the tower body 1, and the curved blocks 14 are located at both ends of the overflow weir 121, and the convex surface of the curved block 14 is connected to the tower. The inner wall of the body 1 is fixedly connected, when the motor 2 rotates, the output shaft 21 rotates, and the rotating shaft drives the scraper 22 to rotate. The arc-shaped arrangement is not easy to make impurities accumulate in the corners, and when the No. 1 rod 25 is in contact with the arc-shaped block 14, the No. 1 r...

Abstract

The invention relates to the technical field of purification of 2, 4-polychlorophenol, in particular to a purification device and method of 2, 4-polychlorophenol. Comprising a spherical groove, a first ball, a first rod, a motor, a scraping plate, a spring, a first block, a tower body and an arc-shaped block; when the motor rotates, the motor drives the output shaft to rotate, the output shaft drives the scraping plate to rotate, when the scraping plate rotates, a first rod in a first groove in the scraping plate makes contact with the inner wall of the tower body and the side face of a first block under the action of a spring, and friction is generated between the end, away from the output shaft of the motor, of the scraping plate and the inner wall of the tower body; and a spherical groove is formed, a first ball is connected into the spherical groove in a rolling mode, and when the scraping plate rotates, the first ball rolls in the spherical groove, so that the friction force of the first rod is reduced, and the service life of the first rod is prolonged.

Description

technical field [0001] The invention relates to the technical field of 2,4-polychlorophenol purification, in particular to a purification device and method of 2,4-polychlorophenol. Background technique [0002] White solid, phenolic odor, flammable. The melting point is 42-43 °C, the boiling point is 210 °C, the relative density is 1.383 (65 / 25 °C), and the flash point is 113 °C. Dissolve 0.45g in 100g of water at 20°C, dissolve in ethanol, ether, benzene, chloroform and carbon tetrachloride; used as a pesticide and pharmaceutical intermediate, a purification process is required in the production process, and it is currently used for the purification of 2,4-polychlorophenol Rectification is mainly used. [0003] There is also a patent in the prior art about a technical solution for a purification device and method of 2,4-polychlorophenol. For example, a Chinese patent with application number CN2018101709954 discloses a plate-type rectifying tower, which includes The tower...
