(54) INSTALLATION FOR WET TREATMENT OF FIBROUS MATERIAL

one

The invention relates to the textile industry and can be used for treating fiber while preparing it for spinning.

A known installation for wet processing of a fibrous material, comprising a humidification chamber, a horizontal screen conveyor arranged therein for moving a layer of fiber, circulation fans, an air preparation system including nozzles, droplet separators, perforated pipes for steam injection, and a system for removing spent agent (air). This machine is characterized by closed circulation of humid air with the flow direction from top to bottom W.

A disadvantage of the known installation is that it does not provide a means for carrying out emulsification of the material being processed in parallel with the process of moistening, and the latter is a significant factor in processing the fiber layer during its preparation for spinning.

The purpose of the invention is to increase the productivity and quality of the fiber in preparing it for spinning.

This goal is achieved by the installation of a wet fiber treatment comprising a mesh conveyor horizontally disposed in the casing and a means for moistening the fiber, including blowing ducts for supplying the moistening agent and suction ducts for outputting

0 b. Fig, 1 shows the installation, general view; in fig. 2 is a section A-A in FIG. on fig.Z - section bb in figure 1; in fig. 4 shows a pressing device for an aerodynamic emulsion distribution system. The installation for wet processing of the fiber in preparation for spraying contains a sectional chamber 1 with a horizontal mesh conveyor 2 located inside, circulation fans 3, pipelines 4 for dispensing water and steam for preparing the moistening agent, aerodynamic vanes 5, dispensing the moistening agent, separator a droplet separator 6 and an exhaust air removal system including an exhaust fan 7. The last section of chamber 1 is equipped with a casing 8 installed above the conveyor 2 and communicating with the atmosphere of the workshop through your air inlet 9, as well as an Emulsion feed system having an emulsion diffuser 10 installed with the possibility of reciprocating a dvigate across the conveyor 2, and an aerodynamic distribution system of the emulsion over the thickness of the fibrous layer, made in the form of two robots 11 and 12 located between the branches of the conveyor 2, and the fan 13, while one of the ducts (11) is installed under the diffuser 10 and the other above the duct (12) A clamping device is installed above the conveyor 2, consisting of a set of punched into alts 14, the sampling probe 15 of the filtered air, which is connected via a conduit 16 to an air removal system 7. The device works as follows. The fiber laid on the conveyor 2 moves through all sections of chamber 1. In the first two sections, the vacuum created by circulation fans 3 is forced to move moist air through the fibrous layer due to vacuum, which results in the air being sorbed by the fiber, the fiber is fine. The air humidification mode is maintained by dispensing hot steam into the air and subsequent cooling with dispersed water distributed through nozzles and pipe nozzles 4. The air flow rate is equalized by the aerodynamic blades 5, the droplet moisture is separated by a separator separator 6. V The last section of the installation is emulsifying the fibrous layer. Due to the vacuum created by the fan 13, air flows from the workshop through the air intake 9 into the working zone of the sections, bounded by the casing 8. The dispersion of the emulsion is produced by the diffusor 10. The emulsion particles from the spray plume (dispersing device) are picked up by the air flow. The biphasic flow thus formed is sucked through a layer of fiber, captured by box 11, and an hour & a half cut box 12 is fed under the layer of fiber for secondary filtration. Secondary filtration of the two-phase flow takes place due to the pressure created by the fan 13 and the vacuum created by the fan 7. With double filtration, the emulsion particles are filtered on the surface of the fibers, processing both the surface and deep layers of the pulp on the conveyor 2, and the cleaned air For example, mine rollers 14, which prevent fiber entrainment and layer separation, are removed by system 7 through probe-inlet 15 via pipeline 16. The treated fiber is dropped from the conveyor and fed to extinguishing technological operations ..,. An apparatus for wet processing of fibrous material, comprising a mesh conveyor horizontally disposed in the housing and a means for moistening the fiber, including blowing ducts for supplying a moistening agent and suction ducts for exhausting air, characterized in that and the quality of the fiber when preparing it for spinning, dHO is equipped with a fiber emulsifying agent containing an emulsion diffuser, specified above the conveyor with the possibility of reciprocating movement across the conveyor, and the aerodynamic distribution system of the emulsion over the thickness of the layer, including a fan, a pair of ducts installed in series along the conveyor between its branches, the first of which is located under the emulsion diffuser and connected to the suction with a tube of a fan and a second perforated roller located above the conveyor in the area of the second duct to hold the fiber layer on the conveyor The casing above the emulsion diffuser is perforated.
