Abstract

The invention discloses a pre-pump filter for a dyeing machine dye vat, and relates to the technical field of pre-pump filters. The pump front filter for the dyeing machine dye vat comprises a dyeing machine filter, wherein an inlet filter screen is arranged in the dyeing machine filter, and an outlet filter screen is arranged on the outer side surface of a connecting pipe. According to the invention, the inlet diameter of the inlet filter screen can greatly reduce the inflow resistance of dye liquor, the flow adaptability is improved, the inlet filter screen conical structure enables impurities to be gradually concentrated to the tail end of the inlet filter screen along with the flow direction of the dye liquor, the blocking risk of the inlet end of the inlet filter screen is reduced, the flow velocity of the dye liquor is accelerated through the shrinkage of the flow channel, the impurities are driven to move towards the outlet direction by utilizing the fluid kinetic energy, the deposition in the connecting pipe is avoided, the outlet filter screen is used as a secondary barrier, the residual tiny impurities are further intercepted, the purity of the dye liquor is ensured to meet the dyeing process requirement, and flaws such as color spots on the surface of fabrics, particle adhesion and the like are reduced from the source.

Description

Pump front filter for dyeing machine dye vat Technical Field The invention relates to the technical field of pre-pump filters, in particular to a pre-pump filter for a dyeing machine dye vat. Background The filter before the pump is a key pretreatment device in a dye liquor circulation path, is usually arranged at the inlet end of the dye liquor circulation pump, and has the core functions of intercepting fiber scraps, undissolved dye particles, auxiliary agent residues and other solid impurities in the dye liquor, preventing the impurities from entering the circulation pump, a heat exchanger, a nozzle and other precise components, thereby guaranteeing the stability of the dyeing process and prolonging the service life of equipment. The existing pre-pump filter only has a sewage outlet and a back flushing water inlet, water is introduced through the back flushing water inlet, and the flow speed of water flow drives a magazine to flow out, so that liquid cannot flow in the pre-pump filter in an accelerating way, the traditional back flushing only flushes the surface of a filter screen through water flow at high pressure of the water inlet, but the water flow is in diffusion-shaped distribution in the filter cylinder, the water flow speed near the central area of the filter screen is remarkably attenuated, impurities such as fiber scraps, auxiliary colloid and the like are retained in the inner pores of the filter screen, the retained impurities can absorb more tiny particles, the filter screen pores are gradually filled, the shearing force formed on the surface of the filter screen by the back flushing water flow is rapidly attenuated along with the increase of the distance, only loose impurities on the surface layer can be stripped, colloid residues tightly combined with the filter screen fiber are difficult to be flushed out, and the colloid retained for a long time is gradually hardened in high-temperature dye liquor, and the equipment load is aggravated.
