Fur niter-dyeing machine

Abstract

The invention discloses a fur niter-dyeing machine. The fur niter-dyeing machine comprises a rotary drum structure, a filtering device and a stirring device. The rotary drum structure comprises a flat and straight baffle plate arranged at the inner surface of the drum body along an axis direction, an inclined baffle plate structure and inlet and outlet water pipes. The filtering device comprises a liquid inlet pipe, a primary filtering device and a secondary filtering device. The opening of a liquid outlet pipe is arranged above the primary filtering device. The primary filtering device comprises a rubber scrubbing brush, a hairbrush and a primary filtering screen. The rubber scrubbing brush is located in front of the hairbrush. The secondary filtering device comprises a secondary filtering screen and a secondary liquid outlet pipe. The stirring device comprises a temperature control device, a steam heating device and an inclined stirring device arranged in the cylindrical shell of the stirring device. A water outlet of the rotary drum structure is connected to the liquid inlet pipe of the stirring device. The primary liquid outlet pipe and the secondary liquid outlet pipe of the filtering device are respectively connected to the primary liquid inlet pipe and the secondary liquid inlet pipe of the stirring device. The fur niter-dyeing machine can be used in fur niter-dyeing and guarantees finished fur quality.

Description

Technical field [0001] The invention relates to a processing equipment in the fur industry, in particular to a fur dyeing machine. Background technique [0002] Rotary drum is a common equipment in the leather industry. It is widely used in wet operations such as soaking, liming, expansion, neutralization, softening, tanning, dyeing, and fatliquoring in the leather production process, but the existing drum has a single internal structure , The mechanical action is strong, and the application in the fur industry is more restrictive. The fur drums usually used are mostly the same as the tanning drums. In the drum body, multiple horizontal small flat baffles and large flats are used. Straight baffle, the height of the large straight baffle is higher than the height of the small straight baffle, so that the fur is raised to a certain height by the large straight baffle during the operation of the drum, and hits the small straight baffle when it slides down , The mechanical action is...

Problems solved by technology

[0002] Drums are commonly used equipment in the leather industry, and are widely used in wet operations such as soaking, liming, swelling, neutralization, softening, tanning, dyeing, fatliquoring, etc. in the leather production process, but the internal structure of the existing drum is single , the mechanical effect is strong, and the application in the fur industry is relatively restrictive, and the fur drums commonly used are mostly the same as the tanning drums, and multiple horizontal small straight baffles and large flat baffles are used in the drum body. Straight baffles, the height of the big straight baffles is higher than the height of the small straight baffles, so that during the operation of the drum, the fur is picked up by the big straight baffles to a certain height and hits the small straight baffles when it slides down , the mechanical effect is relatively large, although the fur becomes softer under the strong mechanical action, but at the same time it is easier to make the fur be knotted, which seriously affects the quality of the finished hide; after the fur is processed in the drum, the bath liquid contains a lot of hair fiber impurities , the existing drum equipment equipped with filter equipment is mostly used to remove wool fibers with rubber brushes, but the bath liquid after treatment with this structure still contains some wool fibers, and the pipes are easy to be blocked after long-term use, and the fur is also easy to knot , which affects the quality of fur in the later stage; the fur processing process requires a large amount of chemical material, and the stirring device for chemical material is generally installed vertically in the agitator cylinder, but there are deficiencies in uneven stirring and chemical blockage in the injection port; In addition, due to the temperature change of the existing stirring device after the chemical material is put in, it is inconvenient to control the temperature in the cylinder.
