Device for adding vat powder into circulation pipeline of ball warp dyeing machine

Abstract

The invention discloses a device for adding vat powder into a circulation pipeline of a ball warp dyeing machine. The device comprises a material adding barrel, a dye liquor equalizing pipe, a dye liquor circulation pipe and a vat powder adding device, wherein the material adding barrel comprises a vat powder adding port; the vat powder adding device comprises a hopper and a spiral propeller; the spiral propeller comprises a propelling screw rod, a driving motor and a reducer; the propelling screw rod is arranged at the bottom of the hopper; a material outlet pipe is arranged on the propelling screw rod in a position above the vat powder adding port of the material adding barrel; the vat powder adding device further comprises a stirring wheel and a transparent plastic sleeve; the stirring wheel is arranged in the hopper and above the propelling screw rod; and the transparent plastic sleeve is sleeved between the material outlet pipe of the propelling screw rod and the vat powder adding port of the material adding barrel. Through the adoption of the device, the vat powder can be added smoothly without waste; and the vat powder is dissolved fast in the material adding barrel.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a device for adding hydrosulfite to the circulation pipeline of a ball dyeing machine. Background technique [0002] In the denim production process, it is usually necessary to add some auxiliary agents and dyes to form a dyeing solution. In the circulation pipeline of the ball-passing dyeing machine with multiple dyeing tanks, in order to control the concentration and the uniformity of the dyeing liquid components of each dyeing tank, generally, the auxiliaries and dyes are not directly added to a certain dyeing tank, but are added to the common The material is added to the tank (or bucket) and evenly distributed to each dyeing tank by the circulation pump. For liquid additives, it can be added directly through a metering pump. For solid additives such as hydrosulfite, hydrosulfite does not decompose in a solid state, and after it is turned into a water-s...

AI Technical Summary

Problems solved by technology

The deficiencies of the hydrosulfite adding device in this system are: (1) under the dyeing and humid environment, the hydrosulfite is easy to absorb the moisture in the air and harden. After the hydrosulfite is hardened, the hydrosulfite above the screw propeller cannot fall down. After the sodium hydrosulfate is added below, there will be an empty area without hydrosulfite above the screw propeller, and the hydrosulfite cannot be added to the material tank by the screw propeller

(2) During the falling process of hydrosulfite from the material outlet of the screw propeller to the hydrosulfate addition port of the material addition tank, the hydrosulfite particles are small and easily scattered, resulting in waste of hydrosulfite

(3) The dissolution rate of hydrosulfite in the material adding tank is slow, there are hydrosulfate particles in the dyeing solution, and the utilization rate of hydrosulfate is low

When the adding speed is fast, it is easy to agglomerate and block the channel, thus affecting its effect
