Low-dose scraper type metering feeding device for dyeing powder auxiliary agent

Abstract

The invention provides a low-dose scraper type metering feeding device for a dyeing powder auxiliary agent. The low-dose scraper type metering feeding device provided by the invention comprises a powder auxiliary agent storage bin, a conical powder auxiliary agent normal-pressure feed-supplementing bin arranged at the lower part of the powder auxiliary agent storage bin, and an L-shaped pipeline bin arranged at the lower part of the conical powder auxiliary agent normal-pressure feed supplementing bin, wherein a feed-supplementing check valve is arranged on a partition plate located between the powder additive storage bin and the conical powder auxiliary agent normal-pressure feed-supplementing bin; the upper end of the L-shaped pipeline bin communicates with the conical powder auxiliary agent normal-pressure feed-supplementing bin through a feeding check valve; one side of the L-shaped pipeline bin is provided with a discharge outlet; the bottom part of the L-shaped pipeline bin is provided with a screw feed-pushing rod; the position, located on the screw feed-pushing rod, of the discharge outlet is provided with a feed-taking scraper; the other end of the screw feed-pushing rod is connected with a variable frequency motor which is connected with an encoder; a stirring bin is arranged below the discharge outlet; a stirrer and a quantitative water supply unit are arranged in the stirring bin; and the discharge outlet of the stirring bin is provided with a metering feeding pump. The low-dose scraper type metering feeding device provided by the invention effectively guarantees the stability of product quality.

Description

[0001] Technical field: [0002] The invention relates to a small-dose scraper-type metering and feeding device for dyeing powder auxiliaries, which belongs to the technical field of spinning equipment. [0003] Background technique: [0004] With the continuous advancement of science and technology and the continuous tightening of environmental protection policies, low liquor ratio and small emissions have become the lowest entry threshold for the printing and dyeing industry today. It has become a modern enterprise to replace labor with machines, replace human brain with computers, reduce manual operations, improve industrial automation, vigorously promote clean production models, reduce and eliminate environmental impact and damage, improve the environment of production sites, and protect employees' occupational health. Necessary for survival. As a printing and dyeing industry, the traditional production methods are mostly manual operation control mode. For example, in the...

Problems solved by technology

Take the delivery aid Yuanmingfen as an example, the minimum water ratio is 3:1. The disadvantage is that the water consumption is large, which invisibly increases the dyeing bath ratio. Stop stirring, otherwise crystallization will occur, resulting in pipe blockage, resulting in system failure and failure to operate; when encountering small doses of additives, there are disadvantages such as differences in measurement accuracy.
