Embodiment 1

[0030] As shown in the drawings, the leather rod separator shown in this embodiment mainly includes a transmission mechanism 1, a drum 2, an outer cover 3, and a vacuum cover 4, wherein the drum 2 is a cylindrical structure, and is located on the outer cover 3. Inside, the rotating drum 2 is connected with the transmission mechanism 1 through the rotating shaft 5 , the rotating shaft 5 is supported by the support frame 6 , the outer cover 3 is an open structure at the front, and a feeding port 9 is provided at the rear. There are several sieve holes distributed on the circumferential surface of the drum 2, and the sieve holes are in an inverted cone structure, wherein, the end of the large hole faces the inside of the drum 2, and the end of the small hole faces the outside of the drum 2, and the diameter of the small hole can be 3-10 mm, and the diameter of the large hole The hole diameter may be 6-15 mm. The cavity of the drum 2 is provided with a number of partitions 10 radi...

Embodiment 2

[0034] A method for separating cotton stalks, mulberry trees, mulberry trees, and other pulverized materials from leather and rods, which adopts leather and rod separation equipment for separation. The raw materials are sent to the skin rod separation equipment, and the relatively broken rod materials are sucked into the cavity of the drum by vacuum suction and discharged, and the longer skin fibers are adsorbed on the surface of the drum and are unloaded with the rotation of the drum.

[0035] As shown in the drawings, the skin-rod separation equipment can adopt the following structure: the drum cavity of the skin-rod separation equipment is provided with a number of partitions 10 radially distributed, and the partitions 10 divide the drum The inner cavity is divided into several relatively independent small chambers 11 along the axial direction. One end of the drum is sealed, and the other end is provided with a shield. The vacuum cover 4 connected to the end of the drum and ...

Abstract

The invention discloses a method for separating bark from a stalk and a bark and stalk separator, mainly relates to a method and equipment for separating barks from stalks of crushed cotton stalk, mulberry trees, broussonetia papyrifera and other raw material for pulping and belongs to the technical field of standby materials in the pulping industry. In the invention, the bark and stalk separating equipment is used for separating and is provided with a rotary drum which can rotate and is provided with sieve holes on the surface; and the crushed materials are fed into the bark and stalk separating equipment, the crushed stalk materials are sucked into a cavity of the rotary drum and discharged by using vacuum sucking force and longer bark fibers are attached to the surface of the rotary drum and detached along with the rotation of the rotary drum. The invention has favorable separation effect and high separation efficiency when being used for separating bark from stalk and can be widely applied to the stand raw material in the pulping industry.

Description

technical field [0001] The invention relates to material preparation in the pulping industry, in particular to a method and equipment for separating skins and rods of pulverized cotton stalks, mulberry trees, mulberry trees and other pulping raw materials. Background technique [0002] The skins and rods of cotton stalks, mulberry trees, and mulberry trees are good raw materials for pulping. In the pulping process, the raw materials generally need to be prepared for the purpose of separating the skins and rods of the raw materials for pulping. At present, there is no effective separation equipment for the above-mentioned pulping raw materials in the paper industry. Contents of the invention [0003] Aiming at the above-mentioned defects in the prior art, the present invention provides a bark separator capable of effectively separating bark and bark from raw materials such as crushed cotton stalks, mulberry trees, and paper mulberry trees. [0004] Equipment of the present...
