A sandwich barrel for refining

Abstract

The invention discloses an interlayer fining barrel for refining. The interlayer fining barrel comprises a refining groove on the outer side, a top cover is arranged at the top of the refining groove, the center of the top cover is connected with fabric via thread loops, side wall retaining plates are arranged on two side walls certainly distant from two sides of the refining groove, and the bottom of the refining groove is provided with a bottom heating steam pipe. The interlayer fining barrel for refining is characterized in that perpendicular steam pipes having certain height are arranged between the side wall retaining plates and the side walls of the refining groove, the perpendicular steam pipes are closed at the top and open at the bottom, and a plurality of horizontal branch pipes with end openings are uniformly arranged along the height direction of the perpendicular steam pipes. The horizontal branch pipes penetrate the side wall retaining plates. Compared with the existing interlayer fining barrel structures, 'interruption' of fining liquid is avoided, and the fining liquid is kept permeating from each batch of fabric. Meanwhile, uniformity of refining is improved, and refining effect is improved.

Description

technical field [0001] The invention relates to a sandwich keg for scouring. Background technique [0002] There are generally two types of training barrels: ordinary training barrels and interlayer training barrels. figure 1 (a) is an ordinary barrel, figure 1 The (b) is the interlayer practice barrel. Ordinary keg is an old-fashioned keg. There is a bottom heating steam pipe (6) at the bottom of the scouring tank (5). The cycle is from bottom to top, so that the silk fabric (2) floats, causing scratches and wrinkle marks, and there is a temperature difference between the upper and lower parts of the vat. [0003] For this reason, interlayer training barrels are often used, that is, side wall baffles (4) are installed on both sides of ordinary training barrels at a distance of 4-5cm from the barrel wall, and the lower edge of the side wall baffles (4) is about 20-30cm away from the bottom of the barrel. The height of the side wall baffle (4) is higher than the upper edg...

Problems solved by technology

However, when this structure is used improperly, it may also cause a "short circuit" in the training liquid, that is, the training liquid does not pass through the pages of each piece of fabric, but flows between the pieces of fabric, so that the pages of the fabric are closed, which affects the uniformity of refining. degree
