Abstract

The invention discloses chemical raw material rapid crystallizing equipment which comprises a crystallizing cylinder, wherein a plurality of vertical crystallizing rods made from heat conducting metalare arranged at the bottom of the crystallizing cylinder; an evaporator is arranged in the bottom of the crystallizing cylinder and is positioned below the crystallizing rods; a crystal scraping plate capable of moving up and down is arranged in the crystallizing cylinder; a through hole is formed in the crystal scraping plate; the crystallizing rods pass through the through hole; a gap below 0.3mm is reserved between the through hole and the crystallizing rods. Due to the high heat conductivity of the crystallizing rods, the solution crystal is crystallized on the crystallizing rods, the crystal scraping plate moving up and down can scrape off the crystal on the crystallizing rods, thus flow of the solution is not influenced, the frozen crystallizing rods are totally exposed to the solution again, and the crystallizing process is accelerated. The equipment disclosed by the invention is used for purifying chemical raw materials.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a rapid crystallization equipment for chemical raw materials. Background technique [0002] In order to obtain pure industrial raw materials, chemical raw material manufacturers often use crystallization to obtain them, and cold crystallization is a commonly used technical method, and cold crystallization requires crystallization equipment. [0003] Crystallization equipment is also called crystallizer. Equipment for crystallization operations. Generally, the saturated solution is cooled or evaporated to a certain degree of supersaturation and crystals are precipitated. [0004] When a saturated solution crystallizes, the crystals reduce the fluidity of the solution, resulting in a decrease in crystallization efficiency. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a rapid crystallization device in which the crystallization...
