Description
Technical field
The utility model relates to the double-group static-indeterminant mesh-beam exciting-vibration Plate type combination bearing beam oversize vibration screen, is particularly useful for classification, dehydration, desliming and de-mediated to the coal granularity, also is applicable to classification, dehydration, desliming and the de-mediated of other material.
Background technology
Vibratory sieve is the capital equipment of coal preparation plant, and its quantity is many, specification is many, accident is also many, and especially large-scale vibrating screen is the key equipment of China old factory of newly-built Large Coal Washing Plant technological transformation.Its screening, dehydration, de-mediated technological effect and reliability are directly connected to the economic benefit of coal preparation plant, and homemade large-scale vibrating screen can't satisfy the actual needs that colliery and coal preparation plant produce owing to technical reason.Traditional vibratory sieve adopts I-steel or square formed steel construction girder as the branching carrier of vibrator in design, only play a supportive role, so the volume and weight of vibrator is bigger, and corresponding sieve nest mass of vibration also strengthens.In case the width of sieve nest cross section surpasses 3 meters, the physical dimension of crossbeam and weight will increase very big thereupon, can cause crossbeam and the processing of pipe beam, assembly technology etc. to be difficult to guarantee thus.Sieve wide at the vibratory sieve more than 3 meters because mass of vibration is bigger, simple grease lubrication vibrator just can not satisfy the ginseng required exciting force of body that shakes, thereby has only the big bearing thin oil lubricant of employing low speed vibrator.Especially straight line shaker has only the synchronized of employing and synchromesh gear to realize.Like this because the restriction of material and mechanical processing technique technical merit, make the vibratory sieve frequent fault that ftractures of fracture of generator tube beam and side plate in use, not only influenced production efficiency, also had a strong impact on the service life of screening machine, this also is that the sieve of constrained vibration for a long time sieve nest cross-sectional width is difficult to strengthen the crucial factor that structural parameters are difficult to break through.The patent No. is: ZL 02112809.x, disclose width that " a kind of large-scale vibrating screen of redundancy meshwork beams excitation " by name well solved the sieve nest cross section and surpassed 3 meters the problem of sieve nest structural steel and the matching problem of the required exciting force of large-scale vibrating screen, but when the compass screen surface width surpasses more than 3.6 meters, its sieve nest overall structure rigidity, spandrel girder structure and integrity problem are just very outstanding, directly have influence on the reliable life and the operation technique effect of vibratory sieve, restricted the development of the super-huge sieve that shakes.Sieve greatly can not be done and can only meet the needs of production to increase number of devices, thereby increases construction cost and production management cost.China is large-scale at present, and super-huge vibratory sieve all is to depend on import.So in these years develop the production domesticization of large-scale vibrating screen and its technology, be the development of China's coal preparation technique technical merit and pressing for of large-scale industrial production always.
The utility model content
In view of the problem that prior art exists, the purpose of this utility model provides a kind of simple in structure, and dependable performance is born the high double-group static-indeterminant mesh-beam exciting-vibration Plate type combination bearing beam oversize vibration screen of excitation intensity.
For achieving the above object, super-huge vibratory sieve of the present utility model comprises screen box, be supported on the elastic support body under the screen box, the static-indeterminant mesh boom device, motor and rubber-tyred flexible connection, be provided with the indeterminate combination spandrel girder of device of shifting block type in the described screen box, discharge end is provided with feeding end and makes up the square type enclosed beam that spandrel girder links to each other; Be interval with the indeterminate combination buttress brace of many group Y shapes on the sieve box side plate; The net beam of described super quiet net boom device is the double-group static-indeterminant mesh-beam exciting-vibration body, double-group static-indeterminant mesh-beam exciting-vibration body and function double-group static-indeterminant support plate is connected in many net beams and forms the inclusion body that a girder system is formed on indeterminate connecting plate and the side plate, vibrator in the super quiet net boom device is 8 level vibrator groups arranged in pairs, with universal coupling it is cascaded, and links to each other with the double-group static-indeterminant mesh-beam body and to constitute the big rigidity excitor of integral net beam.
The indeterminate combination spandrel girder of described device of shifting block type face rigid body is made of indeterminate support plate, the indeterminate connecting plate that is fixed on many crossbeams on the indeterminate support plate and is fixed on many crossbeam outboard end; The indeterminate support plate two ends of described indeterminate combination spandrel girder is a L-square, two end faces of front and back L-square are fixedlyed connected with the rectangular closed beam, opening between discharging end moment type enclosed beam and the combination spandrel girder seals between pan feeding end moment type enclosed beam and the combination spandrel girder; The indeterminate combination buttress brace of described Y type is made of support column, side plate and indeterminate plate, and support column is the arrangement of Y type and is located between side plate and the indeterminate plate; Described motor and rubber-tyred flexible connection are two groups, and symmetry is located at the both sides of sieve box side plate respectively.
Super-huge vibratory sieve of the present utility model is applicable to granular classification of coal, dehydration, desliming and de-mediated.According to the requirement of exciting force size and the requirement of vibrating direction angle, girder is distributed on the indeterminate support plate by reasonable distributed force, net beam body directly ginseng shakes, and has saved the i-beam structure beam or the square formed steel construction beam that support vibrator as girder, thereby mass of vibration is reduced; With the indeterminate combination spandrel girder of device of shifting block type structure, constitute the planar rigidity body of a whole plate, improved the bending-twisting stress ability of sieve nest integral body.The vibrator volume of this mesh-beam exciting-vibration body structure is little, the weight saving of shaking of vibratory sieve ginseng, and the single exciting force that shakes unit reduces, and the kinematic accuracy height can effectively increase the width of sieve nest cross section, improves vibratory sieve unit productive rate and efficient.It is simple in structure, and compact reliable, rigidity is big, bears the excitation intensity height, vibration balancing, and processability of product structure is good, and vibration is steadily reliable, but complete machine subassembly combination installation and transportation.Because reliability of structure, feasible whole comprehensive mechanical performance improves and improves, and can satisfy the Chinese large-sized colliery, and the production of coal preparation plant needs, and at coal, fields such as metallurgy, chemical industry, environmental protection have practicality widely.
