Description
Technical field
The invention belongs to a kind of vibrating machine, be specifically related to a kind of large modular vibratory equipment.
Background technology
China is energy big country, is that big producing country consumes big country, and the efficient utilization of resource has become the grand strategy of country.The development plan of country has been brought great development opportunity to the vibrating machine industry.The central government is in that " national economy and social development 11th Five-Year Plan outline " has explicitly pointed out the major technologies and equipment that will develop significant impact, comprising large-scale metallurgical equipment, large-scale screening washing appliance etc.Coal separation industry 12 planning also proposes: the former coal throughput of unit is at 1,000 ten thousand ton/years, and therefore, system proposes very high request to the maximization of single device, and the separate unit vibratory sieve of this disposal ability at present both at home and abroad all far away the end can reach.
Existing equipment mainly adopts vibrotechnique to have: double oscillating electromotor vibration, the vibration of bi-motor eccentric block, the vibration of single motor synchronous gear box etc.The version that the tradition vibratory sieve adopts and concentrates vibration source, concentrates power transmission.These vibratory sieves all are to adopt sieve beam, sieve nation force structure, compass screen surface is wider, and the vibratory impulse power that sieve beam, sieve nation are born is just larger, and the structure of large-scale vibrating screen weighs tens tons, this just needs to consume the great energy and realizes vibration, but also does not reach the compass screen surface width of need of production.Simultaneously, compass screen surface is wide causes sieving nation, sieve beam fracture very easily.Because existing equipment vibrating body weight is large, even by the damping damping, the impulsive force on ground is appointed so larger.Because vibrations are large, noise is also just natural large.
It is very high to the requirement of material to strengthen the discharging width, to such an extent as to owing to be subjected to the factor affecting such as material, technique, the maximization of vibratory sieve is very difficult, the width vibratory sieve is almost seldom used more than 4 meters, become the embodiment of industry technology strength, in the field of business, become world subject.
On the other hand, owing to be subjected to the restriction of road, bridge, culvert, vehicle, the transportation of large-scale vibrating screen is very difficult.We are difficult to one 5 meters, 6 meters, 7 meters of imaginations even how wider sieve is transported to the industry spot use.Because the transportation difficulty also causes cost of transportation extremely high.
Summary of the invention
Given this, the object of the invention is to provide that a kind of energy consumption is low, vibrations are little, noise is little, maximization is easy, the vibratory equipment of convenient transportation.
For solving above technical problem, technical scheme provided by the invention is, a kind of modularization vibratory sieve is provided, and comprises more than one unit module, and each unit module comprises that a frame, frame top are equipped with mover layer, and the mover layer top is equipped with working lining.The line shaft of described mover layer, the first reversing box, connector, the second reversing box connect in turn, described the second reversing box comprises two pairs of output shafts, be installed with the first eccentric and the second eccentric on every pair of output shaft, described the first eccentric center of gravity is mutually vertical with the line in axle center with the second eccentric center of gravity with the line in axle center; By the spring assembly transferring power, described working lining also is fixed on frame or the ground by the first leaf spring between described working lining and the mover layer, and described spring assembly is mutually vertical with the first leaf spring.
Preferably, described the first eccentric and the second eccentric are eccentric block, eccentric wheel or eccentric shaft.
Further, minimum angle is 45 ° between described spring assembly and the mover layer.
Preferably, described mover layer is rectangular frame, and described line shaft, the first reversing box, connector, the second reversing box are installed on this rectangular frame.
Preferably, described mover layer is cross-shape frame, and described line shaft, the first reversing box, connector, the second reversing box are installed on this cross frame.
Preferably, described the first reversing box is the cross reversing box, and the left and right sides of the first reversing box is symmetrically connected with connector and the second reversing box.
Preferably, described the second reversing box is two transverse axis reversing boxes, and the front and back bilateral symmetry of the second reversing box is equipped with the first eccentric and the second eccentric.
Further, described working lining is connected with ground or frame by damping spring.
Further, described mover layer is connected the second leaf spring and connects with frame, and described the second leaf spring and the first leaf spring are parallel to each other.
Further, between described mover layer and the frame damping device is installed.
What eccentric block of the present invention produced can shake back and forth in 45 ° of directions with joint efforts, has just given the power of working lining work, and the energy of this motion can be changed between mover layer and working lining mutually, and is very little to the impact on ground.Working lining and mover layer are flexible coupling in ground by spring, all impact energys all well by the spring shock absorption of each dispersion and with energy reserve in spring, damping effect further improves.Damping effect improves, just so that noise significantly reduce.
The present invention has adopted modularized design, can adopt the form of splicing to widen the width of work compass screen surface according to user's requirement, to reach the requirement that improves output, maximizes than being easier to.The present invention can be split as individual unit, and transport difficulty reduces greatly, transports to just simply to splice behind the work-yard again and can carry out work.
The present invention is not only applicable to coal separation, Mineral Processing Industry, and the multiple industry of classification, dehydration that needs such as chemical industry, iron and steel all is suitable for, and has widely application.
