Crystal membrane separation equipment for producing fluorescent whitening agent

Abstract

The invention discloses crystal membrane separation equipment for producing a fluorescent whitening agent, which comprises a main body shell for producing the fluorescent whitening agent, and the front end of the main body shell is provided with an observation window capable of observing the state of crystal membrane separation in a box body; a crystal membrane separation box is arranged in the main body shell, the crystal membrane separation box is of a U-shaped hollow structure, a filling plug is arranged on the crystal membrane separation box, and the filling plug is of an opening and closing structure embedded in one end of the top of the crystal membrane separation box; a heating device is arranged at the bottom of the crystal membrane separation box; a partition plate is arranged at the top of the crystal membrane separation box, and a stirring mechanism is arranged on the partition plate; the partition plate drives the stirring mechanism to abut against the upper portion of a crystal membrane separation box arranged in the main body shell. The device is ingenious in structural arrangement and reasonable in arrangement, the crystal precipitation condition can be observed in real time through the observation window, and meanwhile, the device has the beneficial effect of saving a large amount of operation time.

Description

technical field [0001] The invention relates to the technical field of fluorescent whitening agent production equipment, in particular to a crystal film analysis equipment for producing fluorescent whitening agent. Background technique [0002] Fluorescent whitening agent is a kind of fluorescent dye, or white dye, which is also a complex organic compound. Its characteristic is that it can excite incident light to produce fluorescence, so that the dyed substance can obtain a sparkling effect similar to fluorite, so that The substance seen by the naked eye is very white. The principle of fluorescent whitening agent is to absorb the invisible ultraviolet light in the light and emit visible blue light. After superimposing with the yellow light emitted by the fabric, it complements the white light and increases the white light emitted by the fabric. , the naked eye can feel that the white fabric is obviously brighter, which is the brightening effect. The fluorescent whitening ag...

AI Technical Summary

Problems solved by technology

[0003] The commonly used crystal film analysis equipment for the production of fluorescent whitening agents has a slightly insufficient heating and mixing effect, and the temperature insulation effect needs to be improved; in addition, the existing crystal film analysis equipment for the production of fluorescent whitening agents does not have real-time observation of crystals. The precipitation state of crystals in the membrane analysis equipment, and the stirring mechanism in the membrane analysis equipment cannot be quickly taken out and replaced, the operation is more complicated, and a lot of time will be wasted during operation
