Description
Technical field
The present invention relates to the air-cooled bump of a kind of water-cooled and pulverize unit, mainly in cereal processing, industries such as feed processing, chemical industry, medicine, construction material are used for solid granulates shape material is ground into the fine particle of various granularities.
Background technology
Hammer crusher is a kind of disintegrating apparatus of domestic and international all trades and professions extensive use.Hammer crusher is by feed arrangement, rotor, sieve sheet, transmission mechanism and organization.The cross section is the centre that the sieve sheet of circle or water droplet shape is fixed on the hammer crusher body, and rotor comprises a main shaft, is fixed on the hammer leaf frame on the main shaft and is suspended in the hammer leaf on the hammer leaf frame.Rotor is installed in the pulverizing chamber that impales of sieve sheet.During hammer crusher work, transmission mechanism drives the rotor high-speed rotation, and material gets into pulverizing chamber from feed arrangement, and epitrochanterian hammer leaf bump material reaches the pulverizing purpose.After clashing into, the material particles that reaches the finished product granularity requirements can be from the discharging opening discharge of body after passing sieve sheet sieve aperture, and the material particles that does not reach the finished product granularity requirements is then stayed in the pulverizing chamber by the pulverizing of continuation bump.Hammer crusher has that mechanism is simple, versatility good, adaptability is strong and advantage such as safe and reliable.But the material that gets into pulverizing chamber all must reach the granularity that finished product requires through repeatedly clashing into just can be ground into repeatedly; Therefore the kinetic energy of rotor running is most of consumes in driving pulverizing chamber material and rotatablely moves on the heat energy that generates with the friction that can not produce crushing effect, so efficient is low, the energy consumption height is the great shortcoming of existing hammer crusher.In addition, the bump friction material temperature rise that causes being clashed into is higher repeatedly, and the nutriments such as protein that cereals are contained have destruction.When the lower material of thawing such as processing plastic and softening temperature, the too high crush efficiency that not only makes of temperature rise reduces significantly, even the stopping production accident that often causes processing takes place.
Be known as the equipment of percussion grinder in the extensive use of wheat flour milling industry.Percussion grinder is by casing, and rotor part, stator component and motor are formed.Wherein, rotor part comprises the rotor wheel shell, is fixed on the disk rotor dish on the rotor wheel shell and is installed at least 50 rotor pins of at least 3 circle sums on the rotor disk; Stator component comprise cover plate, fixing on the cover board the disc stator discs and be installed in the circle of at least 3 on stator discs total number and be no less than 100 stator pin.
Existing percussion grinder reaches the pulverizing purpose by the material particles that the rotor pin of installing on the high speed rotor rotated dish clashes in the said gap.According to the basic principle of dynamics analysis, the technological effect of bump depends primarily on pin and is clashed into the size of the relative velocity of material particles.Because of the rotor pin is directly to clash into material particles; And the stator pin has been to stop effect that material particles along the circumferential direction moves; So rotor speed is high more, the bump technological effect is good more, and the gap between rotor pin and the stator pin is more little; The effect that stator pin obstacle material particle along the circumferential direction moves is remarkable more, and the technological effect of bump is good more.Analyze in theory, each rotor pin can both form once bump strongly near the moment of each stator pin.Calculate like this, the strong bump that form each second in bump pulverizer casing reaches 30～600,000 times.Analyze from device structure and operation principle, the electric energy of percussion grinder except that the heat energy of rotor no-load running power consumption and the generation of bump material, is used for the energy that comminuting matter consumes exactly.Because the material that gets into percussion grinder is after moment clashes into; Discharge immediately, the heat energy that bump produces rolls more than grinding roller that the bump friction is few repeatedly in pulverizing chamber with hammer leaf, so; Percussion grinder is most effective in all disintegrating apparatus, the equipment that energy consumption is minimum.Many advantages such as that existing percussion grinder has is simple in structure, pulverizing is powerful, price is cheap, and installation and maintenance are convenient, and energy consumption is low and widely applicable; But the material temperature rise of bump back, motor direct connection rotor are also arranged, functions of the equipments can not be regulated and the direct output finished product shortcomings such as (bump back material need just can go out finished product through screen) of unit running.Wherein, The heat energy that the reason of bump back material temperature rise produces except that unusual high-frequency bump accumulates on the rotor stator pin; After also having the high speed rotor rotated that material is thrown away, material strikes casing inner wall strongly, the continuous motor that turns round also can produce great amount of heat energy and accumulate in the casing.Three thermal source comprehensive functions make the material temperature rise of bump back, and its harm is identical with hammer crusher with influence.
