Description
[technical field]
The utility model relates to screening machine, relates in particular to a kind of swinging screening machine.
[background technology]
The swinging screening machine is as a kind of screening plant commonly used in the screening plant, and is comparatively extensive at the grain machinery industry application.The eighties plays the complex fertilizer industry and constantly rises and develop in China, and an important procedure in the complex fertilizer production sieves exactly, the roto-siofter extension set is bigger because of its sieving area, and advantages such as screen cloth easy to clean, replacing are selected for use by many production of compound fertilizer factories.But all adopting jackshaft to rotate, traditional roto-siofter extension set drives the kind of drive that whole sieve nest rotates, rotation direction power is delivered on the main shaft by reductor by motor, rotation by main shaft drives whole sieve nest rotation, and material all accumulates on the edge of sieve nest, so wanting sieve nest rotates normal, the torsional moment that main shaft bore is very big, so the roto-siofter of this kind of drive exists two problems: 1) fault rate is than higher, often takes place that main shaft twists off or bracing frame sealing-off phenomenon; 2) the diameter maximum of screening machine can only be accomplished 1200mm, and length should not surpass 4000mm, and specification major break down again is just more frequent, almost can't run well, and the roto-siofter of Φ 1200 * 4000 can only adapt to the supporting requirement of the production line of 30,000 tons of/year scales.Along with developing rapidly of the construction scale of complex fertilizer in recent years, general production scale has all surpassed 50,000 tons, and from 100,000 tons to 150,000 tons, even the scale that reaches 200,000 tons/year is also very general, therefore, the roto-siofter of traditional structure can not satisfy the supporting requirement of big production capacity production line far away.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of sieve nest diameter can surpass 1200 millimeters swinging screening machine.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of swinging screening machine, comprise frame, sieve nest and transmission mechanism, frame comprises bearing, and bearing block is equipped with in the bearing upper end, and sieve nest comprises screen cloth, bracing frame and main shaft, the bracing frame profile is horizontal cylindric, bracing frame comprises columnar screen cloth installing rack, support bar and spindle mounting hole, and screen cloth is contained on the screen cloth installing rack, and the screen cloth installing rack is connected with spindle mounting hole by support bar; The two ends of main shaft penetrate spindle mounting hole and are installed in the bearing block; Transmission mechanism comprises motor and decelerator, and the output shaft of motor is connected with input shaft of speed reducer, and transmission mechanism also comprises pinion and bull gear, and pinion is contained on the output shaft of decelerator; Bull gear is contained on the neighboring of an end vertically of screen cloth installing rack, and the outer circumference diameter of the internal diameter of bull gear and screen cloth installing rack is suitable, bull gear and pinion.
Above-mentioned pinion is engaged with in the bottom of bull gear.
The beneficial effects of the utility model are, the swinging screening machine adopts the sieve nest outer gear rim kind of drive, and the screening machine diameter can surpass 1200 millimeters, and maximum gauge can reach 2200 millimeters.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment swinging screening machine.
