Problems solved by technology

[0008] In view of the above facts, the purpose of the present invention is to solve the problems of incomplete separation of straw, skin and roughness, poor separation effect, low production capacity and high energy consumption by the existing separation machinery, and then propose a straw removal and peeling and scraping type. The skin-rang separation device, which takes into account the characteristics of high quality and high efficiency under the same energy consumption, removes straw leaves, positions and cuts the straw skin, scrapes off the straw, and separates the straw from the skin. Up to 95%, the processing capacity reaches 2.5t per hour

Embodiment 1

[0088] Example 1: see Figure 1-2 , In the present embodiment, a deleafing, peeling, and scraping type straw husk separation device includes a feeding device, a defoliation device, a positioning and cutting device, a clamping device, a scraping device, and a collecting device; the feeding device , the leaf removing device 3, the positioning and cutting device 4, the clamping device 5, and the scraping device 6 are sequentially installed on the frame 31; the collecting device is installed on the frame and is located under the scraping device 6; the feeding device uses The straw is fed into the defoliation device 3; the defoliation device 3 is used for straw defoliation, tearing the straw blades, tearing off the leaves, and sending the straw into the positioning and cutting device 4; The positioning and cutting device 4 is used for positioning and cutting the straw, longitudinally cutting the straw, and sending the straw into the clamping device; the clamping device 5 is used fo...

Embodiment 2

[0089] Example 2: see Figure 1-4 , the difference between this embodiment and Embodiment 1 is that the straw husk and rang separation device also includes a turning mechanism 1, which is installed on the frame 31 and located above the feeding table 2, including a turning shaft and a turning shaft installed on the turning shaft. on the flip plate. When encountering straw with a large cross-section, the straw can be pushed into the separation device through the turning mechanism 1. The purpose of setting the turning mechanism 1 at the feeding table is to facilitate the feeding of the straw; the feeding device includes a feeding table 2 And the feeding roller 27, the feeding table 2 and the feeding roller 27 are arranged in front and back, and the straw enters the defoliation device 3 through the feeding table 2 under the action of the feeding roller 27; the surface of the feeding roller 27 is designed with a spiral convex The helical protrusion has a pitch of 55mm and a height...

Embodiment 3

[0090] Example 3: see Figure 1-6 The difference between this embodiment and Embodiment 1 or 2 is that: the leaf removal devices 3 are two groups, and are arranged side by side along the width direction of the frame 31, and each group of leaf removal devices 3 includes two upper and lower gaps. The blade removal disks 11 are provided with six rectangular grooves in a circular array on the opposite surfaces of the two blade removal disks 11. The friction plate 10 is installed in the rectangular grooves. The blade removal shaft 12 is installed on the away surface of the blade disc 11 , and the blade removal shaft 12 drives the blade removal disc 11 to rotate. The leaf removing shaft 12 rotates under the driving of the motor, and then drives the leaf removing disc to rotate, and the friction plate tears the leaves off the straw. The two leaf-removing discs 11 arranged up and down rotate in opposite directions at the same speed, which further improves the tearing of the straw by ...

Abstract

The invention discloses a leaf removing, skin cutting and stalk scraping type straw skin-stalk separation device and method, belongs to the technical field of biomass energy utilization, and solves the problems that an existing separation machine is incomplete in straw skin-stalk separation, poor in separation effect, low in production capacity and high in energy consumption. The device is characterized in that a feeding device, a leaf removing device, a positioning and cutting device, a clamping device and a stalk scraping device are arranged on a rack in sequence; the feeding device is usedfor feeding the straw into the leaf removing device; the leaf removing device is used for removing straw leaves, tearing off the straw leaves, tearing off the leaves, and feeding the straw into the positioning and cutting device; the positioning and cutting device is used for positioning and cutting the straw, longitudinally cutting the straw and feeding the straw into the clamping device; the clamping device is used for clamping the straw and driving the straw to move forwards to the stalk scraping device; and the stalk scraping device is used for separating the straw skin and stalk. The device and the method are used for straw skin-stalk separation treatment.

Description

technical field [0001] The invention relates to a separation device and a separation method for husks and husks, in particular to a scraping-type husks and husks separation device and separation method with the functions of removing leaves and collecting straw husks respectively, belonging to the technical field of biomass energy utilization. Background technique [0002] Nowadays, biomass straw is an important biomass resource. The composition of straw skin is lignin and cellulose, which has the characteristics of good toughness and high strength, and can be used in papermaking, wood-based panels and other industries; It is protein, crude fat and cellulose, which can be used as feed and winemaking accessories. When straw powder is used in the production of wood-based panels, the presence of straw rafts results in high water absorption and low density of wood-based panels. Therefore, the separation of husk and rang from straw can give full play to the characteristics of eac...
