A kind of fruits and vegetables impact crusher

Technical field

The present invention relates to a kind of fruits and vegetables impact crusher, belong to the agricultural material disintegrating apparatus; Its operation principle is: agricultural materials such as the fruit of charging aperture feeding, vegetables by stocking cutter rough lumber on the movable knife disc of rotation at a high speed after again through moving, fixed column cutter impact grinding, and then improve the juice ionization rate of the material that is broken, so that alleviate back level solid-liquid separating equipment load, the fragmentation of material before being used for squeezing the juice on fruit, the original vegetable juice production line.

Technical background

A kind of large-scale production mode of China's agricultural byproducts place of production processing is fruit, original vegetable juice production; the main production process is: fruit immersion, conveying, selection, spray Cleaning for High Capacity, lifting, fragmentation, squeezing, filtration, sterilization, can, product are that fruit, original vegetable juice are raw materials for food industries.Fruit on the production line, vegetables are finished Separation of Solid and Liquid through the solidliquid mixture material after the crusher in crushing by cartridge type juice extractor squeezing process, squeezing is the solid-liquid separation technique critical process in the production process, and the juice ionization rate directly influences the production efficiency of crushing juice rate and juice extractor in the solidliquid mixture material after the fragmentation, therefore smashing principle, the method and apparatus of disintegrating machine is analyzed, is studied and design has actual application value.Application number is 00800138.3 patent of invention ' organic breaker ', has described a kind of grater that broken fruit is used, and its operation principle is that material is built pressure through helical feed, the serrated knife chopping; Application number is 200310100269.9 patent of invention ' fruits and vegetables impact grinding method and device ', has described impact grinding method in fruit, vegetables impact grinding principle and the helical feed process.

Summary of the invention

The objective of the invention is to provide a kind of fruits and vegetables impact crusher, disintegrating apparatus before being applied to squeeze the juice on the agricultural material Normal juice production lines such as fruit, vegetables, its target is to pursue higher juice ionization rate in the broken material, so that alleviate back level solid-liquid separating equipment load, improve the production efficiency of crushing juice rate and juice extractor.

Comprise in order to reach the technical scheme that purpose of the present invention takes: cutter head 1 and cutter shaft 2 concentric being connected, burden-guiding cone 3 is fixed on the stocking cutter 4 that also will be installed on the cutter head 1 on the cutter shaft 2 and compresses, moving knife pad 10 is fixed on moving post cutter 9 lockings that also will be installed on the cutter head 1 on the cutter head 1, material stop ring 5 is connected on the cutter head 1 with one heart, blade 6 uniform being connected on the cutter head 1, form same revolving body by part 1-2-3-4-5-6-9-10 and constitute movable knife disc, water blocking ring 15 is connected on the body 13 that is provided with discharging opening 14, stationary knife pad 7 is fixed on fixed column cutter 8 lockings that also will be installed on the machine body cover 11 that is provided with charging aperture 12 on the machine body cover 11, the cutter shaft 2 of movable knife disc is limited the rotation-coupled of axial displacement by the bearing 16 and the brearing bore formation of body 13, machine body cover 11 is installed on the body 13 with one heart, drive unit 17 and cutter shaft 2 coaxial rotation that is connected constitutes a kind of fruits and vegetables impact crusher (as Fig. 1).Power drives movable knife disc by drive unit 17 and rotates in the crushing chamber of body 13 and machine body cover 11 compositions, from agricultural materials such as the fruit of charging aperture 12 feeding, vegetables by 4 rough lumbers of stocking cutter on the movable knife disc after again through fixed column cutter 8, moving post cutter 9 impact grindings, material after the fragmentation self centrifugal force and blade 6 effect under discharge by discharging opening 14, the movable knife disc rotating speed strong more then juice of HI high impact crushing effect ionization rate more is high more, and the disintegrating machine power consumption is big more.

In the above-mentioned fruits and vegetables impact crusher, the blade of stocking cutter 4 can be the straight knife (as Fig. 1,2) that is parallel to cutter head 1 plane of rotation, forms the section principle, and material is a sheet after the rough lumber, is applicable to bar shaped, lobate vegetables impact grinding; The blade of stocking cutter 4 also can be the land cutter (as Fig. 3,4) perpendicular to cutter head 1 plane of rotation, forms the chopping principle, and material is a strip after the rough lumber, is applicable to the fruit impact grinding.

In the above-mentioned fruits and vegetables impact crusher, the along the circumferential direction uniform k of stocking cutter 4 (k=2,3,4,5,6 ...) individual and back rake angle β is installed on (as Fig. 2,4) on the cutter head 1, for straight knife β is slip cutting angle, help material and cut off, help material for land cutter back rake angle β and discharge and impact grinding.

In the above-mentioned fruits and vegetables impact crusher, fixed column cutter 8 and moving post cutter 9 alternately arrange for cylinder is uniformly distributed along the circumference respectively and the number of turns equates, arrangement number of turns p (p=1,2,3 ...) be crushing steps, accompanying

drawing

1,2 is p=2, accompanying

drawing

3,4 is p=3, and the crushing steps p more little then juice of many materials particle size after cracking ionization rate more is high more; The uniform quantity of every loop pillar cutter is determined between circumferencial direction post cutter material by the gap, and this gap width is diminished to the outer ring gradually by inner ring, is convenient to the material that broken step by step back physical dimension progressively reduces and passes through; Radial clearance between fixed column cutter 8 and the moving post cutter 9 is broken gap, and broken gap width diminishes from inside to outside gradually, so that the physical dimension of material diminishes step by step in the impact grinding process.

In the above-mentioned fruits and vegetables impact crusher, the along the circumferential direction uniform q of blade 6 (q=2,3,4,5,6 ...) individual on cutter head 1, the material of being convenient to after the fragmentation is discharged by discharging opening 14.
