Abstract

The invention is intended for washing, impregnating, dyeing and other liquid treatments of fabrics and knitted fabrics in a tow and allows to intensify the treatment process. The device comprises a conveying roller 1, a feed harness from the storage tank 8 to the overflow chamber 2 and further to the ejection chamber 3. The chambers 2 and 3 are connected via interlocked valves 4 to the circulation system. An ejection chamber consists of coaxially arranged annular nozzles that create vortex flows of opposite direction from one nozzle to another.

 N /./

The invention relates to dyeing and finishing equipment of textile industry, in particular to machines for washing, impregnation, dyeing and other liquid treatments of fabrics and knitted fabrics in tow.

The purpose of the invention is to intensify the process.

Figure 1 shows the device; jg in FIG. 2 - ejection chamber; in fig. 3- section A-A in FIG.

The device contains a transporting roller 1 (Fig. 1) for feeding the tow to the overflow chamber 2, the ejection chamber 3 blocked by the valves 4, the circulation system consisting of the combined heat exchanger 5 and filter 6, the pump 7 and the storage bath 8.20

The ejection chamber (FIG. 2) consists of It consists of coaxially arranged annular nozzles formed by at least three walls 9,10,11 and separating rings 12 and 13, at least two, in which tangentially holes 14 are located, directed in each cavity opposite to each other.

The device works as follows 30 times.

Textile fabric, in the form of an endless tow, is loaded into storage tank 8 (FIG. 1), into which the treatment solution is also poured. 5 The transport roller 1 feeds the harness of the treated web to the overflow chamber 2, in which a soft flow of solution is created, which carries along the treated web and determines the speed of its movement.

In the ejection chamber 3, a turbulent flow is created due to at least two vortex flow opposite to each other, which affects the treated web.

Then the harness enters the pressure head of the accumulator and, moving the place with the solution, again enters the transport roller.

Depending on the type of fabric being processed and the processing technology used, the flow force in the chambers can be adjusted interconnected by interlocked throttle valves 4 or a three-way valve.

When processing cloths with a sensitive structure of weaving in

The overflow chamber creates a weak head with a low speed of movement of the solution with the material, in this case most of the flow passes through the injection chamber, in which the turbulence of the solution compensates for the drop in the intensity of impregnation due to the low velocity of the treatment solution.

When processing textile fabrics with a strong structure of interlacing fibers and requiring a high speed wiring harness, the flow in the overflow chamber increases and decreases in the ejector. The treatment process begins to be significantly affected by the solution flow rate factor.

. Adjusting the flow distribution to the chambers is preferable to perform throttling valves, and so. as in this case, it is possible to interlock them according to a certain law of regulation or to carry out regulation separately.

Maintaining the required temperature of the solution is carried out by the heat exchanger 5, made in the same housing with the filter 6. The circulation of the solution is carried out by the pump 7, and this distribution of flow through the chambers maintains a stable flow resistance of the circulating system. ; Intensive impregnation due to the turbulence of the solution in the ejection chamber at low flow rates. It allows reducing the energy consumption of circulation for its circulation).
