Problems solved by technology

[0003] Polypropylene staple fiber non-woven geotextile is made of polypropylene staple fiber. Polypropylene staple fiber can improve the crack resistance, impermeability, abrasion resistance, frost resistance and blast resistance of mortar / concrete. ability and improve the workability of concrete. During the production of polypropylene staple fiber non-woven geotextiles, it is necessary to loosen the raw materials, loosen the compacted and entangled fiber raw materials and remove impurities. At present, in the prior art When the opening device is in use, the separation effect between the impurities and fibers after opening is poor, which affects the quality of opening

Embodiment 1

[0028] refer to Figure 1-4 , an opening device for making polypropylene staple fiber non-woven geotextiles, comprising a housing 1, a feeding hopper 8 is fixedly installed on the top of the housing 1, and a feeding pipe 15 is fixedly installed on the side bottom of the housing 1, The inside of the housing 1 is installed with two rollers 2 through bearings, and the side of the housing 1 is fixedly installed with a driving mechanism 17 connected to the two rollers 2, and the outer side of the roller 2 is fixedly installed with a plurality of opening teeth 4. The inner bottom of the body 1 is fixedly equipped with a filter mechanism 10, and the bottom end of the filter mechanism 10 is fixedly installed with a vibration motor 11, and the bottom of the housing 1 is provided with a rectangular groove 14, and both ends of the rectangular groove 14 are fixedly installed with U-shaped structure support groove 12, a collection box 13 is inserted between the inside of the two support gr...

Embodiment 2

[0036] refer to Figure 2-5 , an opening device for the production of polypropylene staple fiber non-woven geotextiles. Compared with Embodiment 1, the outer side of the feeding pipe 15 is fixedly equipped with a collection cover mechanism, and the bottom end of the collection cover mechanism is passed through a hasp The lock is equipped with a collection box 21;

[0037] The collection cover mechanism includes a collection pipe 20 with an L-shaped structure, and a plurality of filter air holes 22 are arranged on the outside of the collection pipe 20 , and a sound-absorbing net cover 23 is fixedly installed on the outside of the collection pipe 20 .

[0038] When this embodiment is in use, when the device is discharging, the loose fibers inside the housing 1 are transported outward by wind force, enter the device and filter to the inside of the collecting box 21, which improves the convenience of device discharging and is easy to operate. , and through the provided sound-abso...

Abstract

The invention discloses an opening device for polypropylene staple fiber non-woven geotextile manufacturing, and relates to the technical field of building material production. The opening device aimsat solving the problems that when an opening device in the prior art is used, the separation effect between opened impurities and fibers is poor, and the opening quality is affected. The device specifically comprises a shell, wherein a feeding hopper is fixedly mounted at the top of the shell, a discharging pipe is fixedly mounted at the bottom of the side face of the shell, two rollers are mounted in the shell through bearings, and a driving mechanism in transmission connection with the two rollers is fixedly mounted on the side face of the shell. According to the invention, the rollers andopening teeth which rotate oppositely in the shell are used for pulling and loosening incoming raw materials for realizing opening treatment of raw materials, the opened raw materials enter the surface of a filtering mechanism, impurities obtained by opening the raw materials are filtered through vibration, operation is easy and convenient, the separation efficiency between fibers and impurities is improved, and the opening quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to an opening device for making polypropylene staple fiber non-woven geotextiles. Background technique [0002] Non-woven geotextiles (polyester geotextiles, non-woven geotextiles), also known as geotextiles, are water-permeable geosynthetic materials made of synthetic fibers through needle punching or weaving. High tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, non-woven geotextiles use natural polymers such as cellulose as raw materials, fibers made by chemical methods, viscose fibers are Regenerated cellulose fibers, consisting almost entirely of cellulose. The early non-woven geotextiles were all filaments, called viscose filaments, which could also be cut into short fibers, including cotton-type viscose fibers and wool-type viscose fibers. [0003] Polypropylene staple fiber n...
