    • 专利摘要:
    The unit to extract water from a fibrous web, such as in paper making, using paired pressure rollers or pressure plates, has a loose felting layer inserted between the meshed sieves and the pressure bodies. Pref. there are grooves on the outer surface of the pressure rollers in the running direction of a continuous mesh. The meshes and the grooves have about the same capillary suction level, while the felting layer has a capillary suction level which is 10-1000 times greater than that of the meshes and grooves. The design allows the capillary diameter to be increased at small capillary volumes at the separating layer between the filter cakes and the covering.

    专利说明:

    The invention relates to the textile industry. namely, devices for dewatering fibrous webs.
    A device for dewatering fibrous material webs is known, comprising two pressure rollers arranged one above the other with a gap for material passage and having radial channels, and two felt webs, each of which is in contact with a corresponding pressure roller and is located symmetrically with respect to the direction of movement of the web 1.
    A disadvantage of this device is insufficient dehydration of the material webs.
    The aim of the invention is to increase the efficiency of dewatering.
    This goal is achieved by the fact that a device for dehydrating cloths made of fibrous materials., Containing two pressure pads, arranged one for the other f.)) 1m
    for the passage of material and having radial channels, and two felt webs, each of which is in contact with a respective pressure roller and 5 is located symmetrically with the direction of movement of the web, also has two mesh webs in contact with the felt webs, and the mesh webs and pressure rollers have
    10 is the same capillary suction height, and the capillary suction height of the felt webs exceeds the capillary nature of the mesh webs or pressure rollers 10-100 times.
    15 In FIG. 1 shows the proposed device, a general view; in fig. 2 - the same cross section; in fig. 3 is a capillary circuit of a dewatering device.
    20 The device comprises two pressure rollers 1 and 2 arranged one above the other with a gap for the passage of material. Felt l and 5 are located symmetrically with respect to the direction of movement of the blade 3.) E
