Embodiment 1

[0025] Such as Figure 1-7Shown, a kind of chitin raw material crushing device comprises frame 1, and frame 1 is rotatably connected with turntable 2, and frame 1 is vertically fixedly connected with feeding pipe 5 above rotating disk 2, and this feeding pipe 5 is connected with The turntable 2 is arranged concentrically, and a discharge port 6 is formed between the lower end of the feeding pipe 5 and the turntable 2. The cutting pipe 5 is connected with some cutter shafts 7, and the length direction of the several cutter shafts 7 is in line with the diameter of the turntable 2. In the same direction, several disc-shaped cutting knives 8 are rotated on the knife shaft 7, and the lower edges of the several cutting knives 8 abut against the upper side of the turntable 2, and the knife shaft 7 is also fixedly connected with a grinding head 9. , the grinding head 9 is located on the outside of the cutting knife 8, the grinding head 9 includes a fixed sleeve, a grinding knife 14 an...

Embodiment 2

[0027] Such as Figure 1-7 As shown, a chitin raw material crushing device includes a frame 1, a turntable 2 is connected to the inside of the frame 1 for rotation, the turntable 2 is driven by a motor 3, a hopper 4 is fixedly arranged on the frame 1, and a lower part is fixedly connected to the bottom of the hopper 4. Feeding pipe 5, the feeding pipe 5 is perpendicular to the turntable 2 and is coaxially arranged with the turntable 2, and a feeding port 6 is formed between the lower end of the feeding pipe 5 and the turntable 2; the lower end of the feeding pipe 5 is an open end, and the turntable 2 An anti-blocking column 12 is arranged on the position corresponding to the feeding pipe 5. The anti-blocking column 12 is designed in the shape of a truncated cone, and the top of the column is hemispherical. The orientation of the lower chute 13 is the same as the rotation direction of the turntable 2, and the joint position of the anti-blocking column 12 and the turntable 2 is ...

Embodiment 3

[0034] Such as Figure 1-7 As shown, a chitin raw material crushing device, the starting device starts to work, the motor 3 drives the turntable 2 to rotate, the cutter 8, the grinding head 14, and the screen brush 24 start to rotate, and the screen 10 starts to vibrate up and down. Put the chitin raw material in the hopper 4, the raw material moves to the turntable 2 through the feed port 6, and is cut and pulverized by the cutter 8 on the turntable 2, and the action of the spiral cutter 8 and the turntable 2 is controlled by the central position of the turntable 2. Moving to the area of ​​the grinding head 9 at the end of the cutter shaft 7, the area of ​​the grinding head 9 is simultaneously subjected to the cutting action of the grinding knife 14 and the reverse grinding action of the grinding knife 14 and the grinding disc 15, and the material is further pulverized into The finer particles move to the sieve 10 under the impetus of the follow-up particles, pass through the...

Abstract

The invention provides a chitin raw material pulverizing device, and belongs to the production field of chitin. The chitin raw material pulverizing device comprises a rack, a rotary disc is rotationally arranged in the rack and driven by a motor, and a hopper is fixedly arranged on the rack. The lower portion of the hopper is connected with a discharging pipe. The discharging pipe is perpendicularto the rotary disc and coaxial with the rotary disc. A feeding port is formed between the lower end of the discharging pipe and the rotary disc. The side face of the discharging pipe is connected with a cutter shaft perpendicular to the axis of the discharging pipe. The cutter shaft is rotationally sleeved with a cutter. The end portion of the cutter shaft is further fixedly connected with a grinding head. The outer edge of the rotary disc is connected with a girdle-shaped screen in the circumferential direction. A collection chamber is arranged below the screen. The device can achieve automatic chitin raw material pulverizing, and secondary pulverizing of large particles obtained after pulverizing can be achieved. The device has an anti-blockage function and the function of self-cleaningof the screen at the same time, and the device is capable of saving energy, environment-friendly, simple in design and easy to operate and has good market prospects.

Description

technical field [0001] The invention relates to the field of chitin production devices, in particular to a chitin raw material crushing device. Background technique [0002] Chitin, Chitin in English, the chemical name is poly N-acetylglucosamine, often translated as chitin. Chitin is a major component in the cell walls of fungi and the exoskeletons of arthropods, and other animals also contain it. The chemical structure of chitin is very similar to plant cellulose. They are all polymers of six-carbon sugars with a molecular weight of more than 1 million. The basic unit of cellulose is glucose, which is a polymer composed of 300 to 2500 glucose residues linked by al,4 glycoside chains. The basic unit of chitin is acetylglucosamine, which is a polymer composed of 1000-3000 acetylglucosamine residues connected to each other through p1,4 glycoside chains. Chitin is food cellulose, which is not easily digested and absorbed. Chitin can be absorbed if eaten with vegetables, p...
