Problems solved by technology

Because the organic fiber is lighter than cement, when the sorter sorts the cement particles, the airflow in the sorter will take the lead in sending the light fiber to the fine powder outlet, and it is impossible to realize the co-grinding of fiber and powder Purpose

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the examples.

[0030] like figure 1 As shown, a fiber dispersing mill of organic fiber reinforced composite material proposed by the present invention includes a cylinder body, a stirrer 6 , a reducer 2 and a motor 1 . The motor shaft is provided with a driving pulley, the power input shaft of the reducer 2 is provided with a driven pulley, and power is transmitted between the two through a V-belt.

[0031] The cylinder is divided up and down by the grate plate 7 into a mixed grinding bin 5 and an aggregate bin 8 . A cement feeding port 41 and a fiber feeding port 42 are arranged on the upper part of the side of the mixing chamber, and a number of steel balls 51 are arranged inside the mixing chamber 5 . The top of the mixing chamber is provided with a bearing seat 3, and the reducer 2 is arranged just above the bearing seat. The agitator 6 includes a main shaft and a helical blade wound on th...

Abstract

The invention discloses a fiber dispersion mill of an organic fiber enhanced composite material and a fiber dispersion method. The fiber dispersion mill comprises a barrel body, a stirrer, a speed reducer and a motor. The fiber dispersion mill adopts a double-bin design; the upper part of the fiber dispersion mill is a mixing and milling bin and the lower part of the fiber dispersion mill is an aggregate bin. The stirrer and a steel ball in the mixing and milling bin can be used for effectively realizing joint mixing and milling of fibers and cement, surface properties of the fibers are changed and the dispersity of the fibers is improved; the aggregate bin can be used for temporarily storing a mixed and milled composite material; a lower discharging opening of the aggregate bin is connected with a concrete stirring machine and the composite material with a certain mass is discharged at fixed time according to the mixing proportion of the concrete and technological parameters of the stirring machine; meanwhile, the cement and the fibers are added at fixed time respectively through a feeding opening of the mixing and milling bin according to the ratio required by production, so thatcontinuous production work of the concrete stirring machine is realized.

Description

technical field [0001] The invention relates to a fiber dispersion mill and a fiber dispersion method of an organic fiber reinforced composite material, belonging to the technical field of concrete, in particular to organic fiber concrete. Background technique [0002] High strength, high toughness, and high crack resistance are the development trend of the performance requirements of concrete materials in the field of civil construction, and also meet the requirements of large-scale construction projects for the crack resistance and durability of materials. Ordinary concrete is a quasi-brittle material. The addition of suitable fibers can increase the ductility of concrete, improve the tensile, flexural strength and fracture properties of concrete, and meet the material requirements of large-scale construction projects. The fiber content of fiber reinforced concrete currently used in engineering generally does not exceed 1%. When the fiber content exceeds 1%, serious agglom...
