Description

Palm shell hydraulic crushing device

Technical Field

The invention relates to the technical field of crushing devices, in particular to a palm shell hydraulic crushing device.

Background

Palm is a common commercial crop used to produce palm oil, where the palm shell is the largest by-product in the palm oil processing. The palm chitin is hard, the fiber content is high, the fibers are mostly long fibers, the mechanical property is very high, the palm chitin can be processed into a natural fiber material with a textile function through processes such as silk drawing and the like, and the palm chitin can be used for producing wood-plastic composite materials through crushing and drying. Because the palm fibers have large length-diameter ratio, high specific strength and good toughness, the mechanical strength of the wood-plastic composite material produced by the palm fibers with large length-diameter ratio has great advantages compared with the mechanical strength of the traditional biomass fibers such as wood powder, bamboo powder and rice hulls. However, the palm shells are processed into biomass fibers suitable for producing wood-plastic composite materials through crushing, which cannot be realized by adopting the traditional wood fiber processing equipment, and special equipment is required to be adopted to crush the palm shells.

Disclosure of Invention

The invention provides a palm shell hydraulic crushing device aiming at the problems of high palm shell hardness, low crushing efficiency and high blade abrasion speed in the palm shell fiber preparation, production and processing process of palm shell resources.

In order to achieve the purpose, the application is realized by the following technical scheme:

the utility model provides a palm shell hydraulic crushing device, includes cutter mechanism, cutter mechanism includes cutter, roof and master cylinder to fix on the base, the cutter is fixed to be set up on the roof, the roof is through ejector pin connection master cylinder, cutter mechanism top has set gradually medium plate and upper plate, is continuous with the base by four stands.

Furthermore, a plurality of cutter holes matched with the cutters are formed in the middle plate and used for positioning the cutters and ensuring the stability of the cutters in up-and-down motion.

Furthermore, the middle plate is connected with a side cylinder through a side ejector rod, and the side cylinder is fixed on the side edge of the base.

Furthermore, the number of the side cylinders is two, and the two side cylinders are respectively arranged on two opposite side edges of the base.

Further, the master cylinder is located at a central position inside the base.

Furthermore, the upper plate is fixed above the upright post, the middle plate penetrates through the upright post and can slide up and down on the upright post, and the vertical distance between the upper plate and the middle plate forms a material crushing area.

Aiming at the characteristics of large single volume, high hardness, large length-diameter ratio of fibers and good toughness of the palm shells, the crisscross pressing knives are introduced in the crushing process to carry out high-pressure pressing and binding on the palm shells, and the palm shells are primarily crushed. The device simple structure, work efficiency are high, and the stripping and slicing homogeneity is good, is fit for batch industrial production.

Detailed Description

The invention is further illustrated by the following specific examples. The starting materials and methods employed in the examples of the present invention are those conventionally available in the market and conventionally used in the art, unless otherwise specified.

Example 1

As shown in figure 1, the palm shell hydraulic crushing device comprises an upper plate 1, a middle plate 2, a cutter hole 3, an upright post 4, a base 5, a top rod 6, a top plate 7, a cutter 8, a side top rod 9, a main cylinder 10 and a side cylinder 11. The main cylinder 10 is located in the center of the inside of the base 5, the cutter 1, the top plate 6 and the main cylinder 10 form a cutter mechanism, and the cutter mechanism, the middle plate 2 and the base 5 are connected through four upright posts 4 to form a whole hydraulic crushing system.

The cutter 8 is fixedly arranged on the top plate 6, the top plate 7 is connected with the main cylinder 10 through the ejector rod 6, and the middle plate 2 and the upper plate 1 are sequentially arranged above the cutter mechanism and are connected with the base 5 through the upright posts 4.

Set up the knife hole 3 of a plurality of and cutter 8 adaptation on the medium plate 2 for fix a position cutter 8 and guarantee cutter 8 up-and-down motion's stability, medium plate 2 links to each other with side jar 11 (setting up two) through side ejector pin 9, and side jar 11 is fixed at base 5 side.

The upper plate 1 is fixed above the upright post 4, the middle plate 2 passes through the upright post 4 and can slide up and down on the upright post 4, and the vertical distance between the upper plate and the upright post forms a material crushing area.

Example 2

The palm fibers have large length-diameter ratio, high specific strength and good toughness, and the mechanical strength of the wood-plastic composite material produced by the palm fibers with large length-diameter ratio has great advantages compared with the mechanical strength of the traditional biomass fibers such as wood powder, bamboo powder and rice hulls. However, the palm shells are processed into biomass fibers suitable for producing wood-plastic composite materials through crushing, which cannot be realized by adopting the traditional wood fiber processing equipment, and special devices are required to crush the palm shells.
