Abstract
The utility model discloses a vibrating sieve combined frame for mineral processing used in mines, comprising a screen frame (1) and a combined frame (4) being characterized in that the combined frame (4) and the screen frame (1) are sleeved together parallelly, the two ends of the combined frame (4) and the screen frame (1) are separately provided with a fixed crosspiece (3), on one end a clip ring (2) is arranged between the fixed crosspiece (3), on the other end an external thread (5) is arranged, and a ball-nut (6) is arranged to be fastened with the external thread (5), compared with ordinary vibrating sieves, the utility model has the advantages of reducing the accidents such as the cracking of the level frame of the sieve, lengthening the service life of the vibrating sieve, reducing the cost for manufacturers, increasing economic benefits and being particularly suitable to be applied in grading mineral processing in mining.
Description
Technical field:
The utility model belongs to the technical field that mine mechanism is made, and is specifically related to a kind of vibrating screen combobox for ore dressing in mining, is adapted to mining classification ore dressing vibratory sieve.
Background technology:
Known to the inventor, vibratory sieve plays considerable effect in mine ore dressing at present, be that product is carried out category filter, improve the product degree of purity, adapt to different size, satisfy the demands, increase one of important means of the performance of enterprises, the vibratory sieve combo box plays a part to connect boxboard and whole skeleton in equipment, for a long time, horizontal frame fracture accident just often appears in the vibratory sieve that uses in the mine ore dressing equipment always, though adopt steel pipe to replace the steel axle to do the service life that the vibratory sieve combo box has prolonged the vibratory sieve combo box, but disconnected frame accident constantly appears, should be 7 years the service life that vibratory sieve is general, but because disconnected frame accident constantly occurs, so generally use the possibility of scrapping just arranged in 2 years, it is moving that the centrifugal rebound power that vibratory sieve produces by vibrator fully produces with chatter sieve nest, force the way across in the amplitude of frequency at height, screen frame is also along with converse beating about the sieve nest, it is big that the vibration that continues increases combo box stress, the up and down crooked stress symmetric circulation of screen frame, reach the certain limit fatigue data fracture accident just takes place, bring the certain economic loss for manufacturing industry or user, more external enterprises adopt the horizontal frame of vibratory sieve are strengthened the use diameter, adopt the structure of different-thickness up and down, cause asymmetric Cyclic Stress state easily, can not change at the stress value of vibratory sieve on the same stage.Fracture accident still can constantly take place.
Summary of the invention;
The purpose of this utility model is at above deficiency, a kind of different sieve types that provide, and different parts can reduce the horizontal frame fracture accident of sieve nest, prolongs the vibratory sieve vibrating screen combobox for ore dressing in mining in service life.
The utility model is to realize like this, its structure of described vibrating screen combobox for ore dressing in mining is made up of screen frame (1) and combo box (4), it is characterized in that combo box (4) is parallel is nested with on screen frame (1), combo box (4) respectively is provided with fixing shelves (3) with screen frame (1) two ends, the fixing shelves of one end (3) are provided with a snap ring (2) with screen frame (1), the other end is provided with outer rib-loop card (5), and coupling is provided with nut (6) and outer rib-loop (5) fastening.According to difference sieve type and different positions, select the screen frame of unlike material specification for use, be the suitable adjusting process that satisfies condition, fixing shelves of snap ring and locking device, excellent steel is made, to strengthen elastic modelling quantity and fatigue resistance, behavioral characteristics according to combo box adopts the external energy input mode, allowing to mate locking with the range of stress, increase stiffness, improved the stress state of vibratory sieve combo box, its operation principle is a vibratory sieve under the centrifugal rebound power effect that vibrator produces, and it is moving that sieve nest is produced with chatter, forces the way across in the amplitude of frequency at height, screen frame is also along with converse beating about the sieve nest, though it is big that the vibration that continues can make combo box stress increase since at this screen frame by screen frame (1) and combo box (4) coaxial composition, shared crooked stress symmetric cyclic force about the screen frame jointly, make screen frame be difficult to the fatigue data that reaches capacity, avoided generation screen frame fracture accident
Adopt the advantage of vibrating screen combobox for ore dressing in mining of the present utility model to be, the one, improved at the whole stiffness of sieve, prolonged at sieving service life; The 2nd, reduced stopping production maintenance time, improved enterprise's labor productivity; The 3rd, reduce and resolve the frame accident, save raw material and reduced entreprise cost, increased economic benefit.
Description of drawings:
Accompanying drawing is the vibrating screen combobox for ore dressing in mining structure chart
Among the figure: 1. screen frame, 2. snap ring, 3. fixing shelves, 4. combo box, 5. outer rib-loop card, 6. nut
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing embodiment, vibrating screen combobox for ore dressing in mining as shown in drawings, be to select a kind of elasticity strong by specification, the steel tube of material that fatigue resistance is good is made as combo box (4), with combo box (4) parallel sleeve on screen frame (1), combo box (4) respectively is provided with fixing shelves (3) with screen frame (1) two ends, the fixing shelves of one end (3) are provided with a snap ring (2) with screen frame (1) and fix, the other end is provided with outer rib-loop card (5), and coupling is provided with nut (6), adopts that bolt type is fixing to get final product.
The utility model adapts to and general medium-sized and small enterprises production, does not need to increase any equipment.
