Technical field
The present invention relates to a kind of crushing mechanism of non-metallic material, the vertical impact crusher of a kind of built-in effectively power transmission specifically.
Background technology
In the last few years, energy-saving and emission-reduction, environmental protection had penetrated in the development of whole industry, and mining machinery machinery industry is no exception.In order to preserve the ecological environment, realize sustainable development, many places have forbidden exploiting river sand, and one of reason is through for many years after excess exploitation sandstone, and not only river channel ecology environment and river course can't bear the heavy load safely, and resource closely exhaustion.Machine-made Sand all has superiority than natural sand in intensity, modulus of fineness are controlled, and Machine-made Sand replaces natural river sand to be inevitable trend.Vertical impact crusher has shaping and broken two large functions concurrently, is the standard device of artificial sand making, under national policy and industry background, has future and larger puts space to good use.
At present, in order to adapt to the requirement of different industries and different user, the vertical impact crusher model installed power of ting model is 30kW, and the power of large model reaches 630kW, can be described as the sizable equipment of energy consumption.As the standard device of sand processed, its sand effect processed is subject to industry approval always, but excessive also the enduring to the fullest extent of energy consumption denounces.Succeed in developing so far from vertical impact crusher, performance is greatly improved, but the change that main composition parts are not large.Typical vertical impact crusher building block has: feed hopper (10), crusher chamber (20), impeller (30), main shaft assembly (40), pedestal (50) and power part (60), power part (6000) is external, is provided with vertical machine (6001), is main shaft assembly (40) through V-belt (6004) by power transmission.In this process, electric energy conversion is mechanical energy and through transmitting, there is certain loss.The efficiency of motor is generally between 90% ~ 95%, and the efficiency of V-belt is about 90%.
The reason that vertical impact crusher installed power is large has:
1, broken demand own.
2, transmission link loses, and can reach 10%.
3, motor loss, generally between 5% ~ 10%.
Summary of the invention
Present invention eliminates power transmission link, effectively power is built-in, and be integrated with main shaft assembly, it compared with prior art can in same production declining low energy consumption 10% ~ 20%, can significantly reduce disintegrating machine volume simultaneously, reduce occupation area of equipment, make equipment compact more, have good market prospects.
In order to achieve the above object, the vertical impact crusher that a kind of built-in effectively power of the present invention transmits, be provided with feed hopper, crusher chamber, impeller, pedestal, support, electro spindle assembly forms, support is provided with in the pedestal of cylinder type, electro spindle assembly is vertically fixed on support, electro spindle assembly has an armature spindle, impeller is arranged on armature spindle, Direct driver impeller High Rotation Speed, the material fallen into continuously wherein accelerates by the impeller of High Rotation Speed, and high-speed projectile is in crusher chamber, material mutually collides in crusher chamber, grinding, friction, thus realize broken.
Described electro spindle assembly is arranged on the support in pedestal, cylindrical shape, is the power unit of disintegrating machine, is also the main shaft assembly of disintegrating machine.
The cylindrical shape of described pedestal, upper end is provided with flange, and inside is provided with support, and for fixing electro spindle assembly, outer wall is provided with maintenance window.
Described crusher chamber is cylinder chamber shape, and inwall is provided with liner plate, is used for protecting crusher chamber, is provided with counterpunch board, is used for resisting the impact of hitting impeller material in chamber.Lower end is provided with flange and is connected with pedestal, and outer wall arranges access door.
Described feed hopper is made up of inside and outside two cylindric cavitys: lumen centers is provided with material separating disc, and for buffering and uniform-distributed feeding, centre bottom has a material-dropping hole, and the material through material-dropping hole flows into impeller; Cylindrical wall is evenly equipped with 4-6 spout hole, too much material can fall in crusher chamber by spout hole, increases crusher chamber endoparticle cloud density, improves crushing effect; Exocoel lower end is provided with flange, is connected with crusher chamber by bolt.
The balanced component that described impeller is made up of upper and lower disk and middleware, upper disk center is provided with charging hole, is generally provided with 2-5 material outlet between upper and lower disk, impeller during work can continually by materials casting in crusher chamber.Also be provided with wear strip in addition to protect leaf body body.
Traditional vertical impact crusher is except feed hopper, crusher chamber, rotor, main shaft assembly, pedestal composition, also be provided with two (or single) power parts, power part is provided with motor, motor base (frame), slide case, belt stretcher, belt wheel and V-belt usually, whole power part is external, by V-belt, power is sent to main shaft assembly, so also have an appointment 10% energy loss in transmittance process.
Traditional vertical impact crusher external power, due to bel-drivenn efficiency, not only increases disintegrating machine power demand, increases weight and the volume of equipment simultaneously, unfavorable and energy-saving and cost-reducing.
And a kind of vertical impact crusher of power built-in overcomes above-mentioned shortcoming, eliminate V--belt Drive link, energy consumption is made to reduce by 10% ~ 15%, while decreasing disintegrating machine noise and caloric value, device length size is made to reduce about 50%, height dimension reduces about 30%, makes equipment compacter, is more suitable for little job space and produces.
