Novel drum type scouting machine

Abstract

The invention discloses a novel drum type scouting machine. The novel drum type scouting machine is mainly used for the pre-treatment of the textile industry. A round drum is arranged in a main cylinder body, a main circulation pump, a heat exchanger, a filter and the like are arranged at the outside, and a main scouting solution circulation loop is formed through connecting with the main cylinder body through a pipeline. The scouting solution performs forced circulating flow in the loop through the main circulation pump, the processed textile is placed in the drum, a transmission system of the equipment drives the drum to rotate to rotate the textile, and relative movement with high speed is generated between the rotating textile and flowing scouting solution. The novel drum type scouting machine has advantages of large cloth capacity, small bath ratio, water saving, energy saving, high automatic degree, convenience in operation and good technological reproducibility.

Description

technical field [0001] The invention relates to a scouring machine used in the pretreatment of rope-shaped fabrics in the textile dyeing and finishing industry. Background technique [0002] Drum refiner is a pre-treatment equipment used in the dyeing and finishing industry for polyester fabric imitation silk desizing, alkali weight reduction, washing, scouring and relaxation, untwisting and wrinkling, etc. The characteristics of the traditionally used rotary drum scouring machine are: the coil heater built in the main cylinder is used for heating, which takes up a large space, and the temperature control of the scouring liquid in the cylinder is inaccurate and the temperature uniformity is poor; The drum is generally a polygonal structure such as hexagonal or octagonal, the effect of driving and beating the fabric is not optimal, and due to the space occupied by the heater, its maximum rotation diameter is generally less than 85% of the cylinder diameter, and the fabric hol...

Problems solved by technology

The characteristics of the traditionally used rotary drum scouring machine are: the coil heater built in the main cylinder is used for heating, which takes up a large space, and the temperature control of the scouring liquid in the cylinder is inaccurate and the temperature uniformity is poor; The drum is generally a polygonal structure such as hexagonal or octagonal, the effect of driving and beating the fabric is not optimal, and due to the space occupied by the heater, its maximum rotation diameter is generally less than 85% of the cylinder diameter, and the fabric holding space of the drum Small, less cloth capacity; no main circulation pump and feeding barrel, water enters the vat during work, there is a high liquid level in the vat, alkali or other scouring agents are directly poured into the vat to dissolve and dilute, the fabric in the drum can be Most of them are immersed in the scouring liquid, and the drum drives the fabric to rotate, but the scouring liquid does not circulate, so the disadvantages are: 1. The relative movement speed of the fabric and the scouring liquid is small, the scouring efficiency is low, and the fabric scouring permeability is poor; 2. The concentration and temperature uniformity of the scouring agent are poor, and the uniformity of the fabric is poor; 3. The fabric needs to be completely immersed in the scouring liquid for exchange, and the required liquid volume is large, so the bath ratio is high, and the bath ratio exceeds 1:12. Large consumption of scouring agent and heating steam, not only high energy consumption, but also large amount of sewage; 4. Low degree of automation and many human intervention factors
