Abstract

The invention relates to a processing method of separating a cotton stalk skin from a cotton stalk core mechanically as well as special equipment. Firstly, the cross section of a cotton stalk is squeezed to be of a flatly cracked shape and caused to present a continuous shape along the longitude direction; secondly, the flatly-cracked cotton stalk is struck every a certain length to be bent 85 to 90 degrees rapidly, thus leaving the skin separated from the core preliminarily. A free high-frequency strike is conducted to the strap-shaped cotton stalk skin to remove the broken core residue; and finally, the strap-shaped cotton stalk skin is conducted a cross free strike with a frequency higher than the frequency in the second step to eliminate the remaining attached core residue and obtain an eligible cotton stalk skin. The special equipment consists of a squeezing device, a vertical striking device, a diverted striking and skin separating device together with a wallboard and a stand that are used for fixing the devices and all the devices are arranged in sequence. The mandrel of each device is arranged in parallel, supported and fixed by the wallboard and driven by a drive mechanism. The special equipment can realize a mechanical separation of a cotton stalk skin from a cotton stalk core. The processed cotton stalk skin takes the shape of a continuous strap and can be processed further. The processed cotton stalk core takes the shape of millimeter-level crumbs and is an excellent material for pulping and paper making.

Description

technical field

[0001] The invention relates to a bast separation method and equipment, in particular to a mechanical separation processing method and special equipment for cotton stalk sheath core. Background technique

[0002] Cotton stalk skin can become textile fiber after degumming, and cotton stalk core is an excellent raw material for pulp and papermaking. So far, because the peeling of cotton stalks is very difficult, manual peeling can only be used, and there is no method and special machinery for mechanically peeling cotton stalks in the technology. The manual peeling method has high labor intensity and low labor efficiency, and is not industrially feasible. Tens of millions of tons of cotton stalks in my country cannot be comprehensively utilized every year.

[0003] The automatic stripping method and equipment of hemp fiber, which also belong to the plant fiber category, cannot be directly applied in this field, because compared with the same kind of hemp bast, ...

Examples

Embodiment 1

[0029] Embodiment 1: A kind of mechanical separation method of cotton stalk bark and rod core, its production steps are:

[0030] Step 1: Squeeze the cross-section of the cotton stem into a flat shape so that it is in a continuous shape in the longitudinal direction;

[0031] Step 2: Push the flat-cracked cotton stalk horizontally, and apply striking force at intervals of 2mm to make it bend 85°-90° quickly. The bark is separated and the bark of the cotton stalk is still in the continuous range of bands;

[0032] Step 3: Freely pluck the ribbon-shaped cotton stalk bark at a high frequency of 160 times per second to remove the residues and broken cores attached to the cotton stalk bark;

[0033] Step 4: Cross-free plucking with a plucking frequency higher than Step 3, to effectively remove debris still attached to the cotton stalk husk, and obtain qualified cotton stalk husks.

Embodiment 2

[0036] Embodiment 2: A kind of mechanical separation method of cotton stalk bark and rod core, its production steps are:

[0037] Step 1: Squeeze the cross-section of the cotton stem into a flat shape so that it is in a continuous shape in the longitudinal direction;

[0038] Step 2: Push the flat-cracked cotton stalk horizontally, and apply striking force at intervals of 6mm to make it bend quickly by 85°-90°. The bark is separated and the bark of the cotton stalk is still in the continuous range of bands;

[0039] Step 3: Freely pluck the strip-shaped cotton stalk skin at a frequency of 70 times per second to remove the residue and broken cores attached to the cotton stalk skin;

[0040] Step 4: Cross-free plucking with a plucking frequency higher than step 4, to effectively remove the debris still attached to the cotton stalk husk, and obtain a qualified cotton stalk husk.
