Size filtering device, size filtering method and sizing equipment

Abstract

The invention discloses a size filtering device, a size filtering method and sizing equipment. The size filtering device comprises a first size tank, a second size tank, a first size pipe, a second size pipe, a communicating pipe, a flow detection mechanism, a circulating pump, a filtering mechanism and a control mechanism, wherein the first size tank is communicated with the second size tank; thefirst size tank and the second size tank can realize one-way flow of size; the first size tank is communicated with the liquid inlet end of the filtering mechanism through the first size pipe; the second size tank is communicated with the liquid outlet end of the filtering mechanism through the second size pipe; the flow detection mechanism and the circulating pump are arranged on the second sizepipe; the communicating pipe is communicated between the first size pipe and the second size pipe and enables the first size tank, the second size tank, the flow detection mechanism and the circulating pump to form a passage; and the control mechanism comprises a first control valve arranged on the first size pipe, a second control valve arranged on the second size pipe and a third control valvearranged on the communicating pipe. The size filtering device is high in safety.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a slurry filtering device, a slurry filtering method and sizing equipment. Background technique [0002] In the field of textiles, the function of sizing is to improve the breaking strength and abrasion resistance of the yarn, make the hairiness stick to it, and maintain the original elasticity of the yarn, thereby improving the efficiency of the loom. The size has a major influence on the sizing effect of the sizing process. In addition to the concentration and viscosity of the size meeting the standard, the size must also be clean and free of impurities. In the actual sizing process, when the yarn is soaked in the size solution, a large amount of hairiness fibers will fall off in the size solution. With the temperature change of the size tank and the size solution, a large number of floating objects such as particles and blocks will be produced in the size solution. or sediment. Impur...

AI Technical Summary

Problems solved by technology

Impurities in the size will adhere to the surface of the yarn with the circulation of the size during the start-up process, causing size spots to cause quality accidents such as yarn breakage and light size, which seriously affect the sizing effect of the yarn

In the general sizing process, in order to improve the quality of sizing, a filter can be used to remove impurities in the slurry, but the filtered impurities are easy to block the filter, and the operator cannot find out that the filter is blocked in time and accidents occur
