Abstract
A separating lathe exciter for wind-powered jigging dry-process coal separator belongs to the technical field of separating equipment which is used to improve the separating efficiency, The utility model includes a vibrating motor and elastic components. The vibrating motor is fixed with the separating lathe, and the rotating shaft of vibration motor is arranged in vertical position to the sieve plate of the separating lathe. According to the features that the wind-powered jigging dry process coal separator utilizes the wind as the medium and form wind jigging layers for materials to be separated, the utility model adopts the design where the vibrating motor of the same specifications as the exciter is symmetrically installed and the output rotating shaft of the vibrating motor is arranged in vertical position to the working interface of separating lathe. The design ensures that the vibrating direction of separating lathe is the same as the output direction of the material so that the vibrating motor does not need to bear the impact of the vertical movement of the material. On the separating lathe, materials can be carried into the feeding device in a short time during the process of upbearing, jigging and lamination by wind force, thereby ensuring high separating rate, lower power of vibrating motor and effective energy saving.
Description
Technical field
The utility model relates to a kind of solid separation equipment, is a kind of exciting device that utilizes air for the pneumatic separating bed of spoil and troilite grain in medium, the sorting raw coal specifically, belongs to the separation equipment technical field.
Background technology
Contain a large amount of ash contents and troilite grain in the raw coal, generally make its ash content reduce about 10% and can do the use of electric power coal through primary election.The content of ashes that reduces in the raw coal can improve coal-fired fuel value on the one hand, can also reduce the expense of coal aspect transportation, processing on the other hand greatly.China adopts the hydraulic jigging coal separation more, this be a kind of be medium with water, make material in the fluctuating flow that rises and descend, by the different methods that realize sorting of density.Adopt the hydraulic jigging coal separation will expend great lot of water resources, this present situation for China's water resources shortage is very disadvantageous.At present, also have dry coal preparation, thisly can solve wet coal preparation consumption of water resource drawback undoubtedly, but the dry coal preparation technology that is that all right is ripe, still need at aspects such as energy consumption, the efficiencies of separation and constantly grope to improve.If any a kind of dry coal preparation machine is the equipment that utilizes a kind of similar air table, adopts wind-force with material loosening, picking-up, realizes material layering, and the cleaned coal that sub-elects by its side discharging, is realized dry separation under the vibration of sorting bed.This equipment material in assorting room is a curve at a minute bed exercise track, has problems such as the efficiency of separation is lower.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of sorting bed direction of vibration the air jigging dry coal preparation machine sorting bed exciting device consistent with the material outbound course.
The alleged problem of the utility model is solved by following technical scheme:
A kind of air jigging dry coal preparation machine sorting bed exciting device, described exciting device is positioned at an end of sorting bed, its special feature is: involving vibrations motor 2 and elastic parts 3 in the formation, described vibrating motor and sorting bed 1 are affixed, and vibrating motor rotating shaft 2-1 is vertical with the compass screen surface that sorting bed sieve plate 5 constitutes.
Above-mentioned air jigging dry coal preparation machine sorting bed exciting device, described vibrating motor is an even number, its parameter is identical, is separately positioned on the both sides of sorting bed longitudinal centre line 8, and identical, the switched in opposite of the motor speed of center line both sides.
Above-mentioned air jigging dry coal preparation machine sorting bed exciting device, described sorting bed 1 are obliquely installed to discharge end by feeding end, and it is distolateral that described exciting device is positioned at sorting bed feed.
Above-mentioned air jigging dry coal preparation machine sorting bed exciting device, described elastic parts 3 one ends and sorting bed 1 are hinged, and the other end and frame 4 are hinged.
The utility model is medium with the air according to the air jigging dry coal preparation, sorting material is formed the work characteristics of air jigging layering, adopting exciting device is that same specification vibrating motor symmetry is installed, the rotating shaft of vibrating motor and the vertical design of sorting bed compass screen surface, this design makes the direction of vibration of sorting bed consistent with the outbound course of material, vibrating motor need not to carry material and throws motion, material relies on wind-force to hold up on the sorting bed, jigging, enter discharge device with stroke in the delaminating process than section, so efficiency of separation height, vibrating motor power is less relatively, reaches the purpose of efficient energy-saving.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the machine operation schematic diagram.
Number in the figure is expressed as follows: 1. sorting bed; 2. vibrating motor; 2-1. machine shaft; 3. elastic parts; 4. frame; 5. sieve plate; 6. exhaust end; 7. material feeding end; 8. sorting bed longitudinal centre line.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model is installed in the material feeding end of air jigging dry coal preparation machine sorting bed 1, and as seen from the figure, the high-end of sorting bed is material feeding end 7, and low side is an exhaust end 6.Throw the work characteristics of material according to the air jigging dry coal preparation by loose picking-up material of normal pressure wind and fluctuating wind, the vibration of sorting bed need not to throw motion for material provides again, so the mounting means of vibrating motor is different with common screening plant.Vibrating motor is an even number, and vibrating motor 2 is affixed with the sorting bed, and vibrating motor rotating shaft 2-1 is vertical with the compass screen surface that sorting bed sieve plate 5 constitutes.Every pair of vibrating motor specification is identical, be separately positioned on the both sides of sorting bed longitudinal centre line 8, and the motor steering of center line both sides is opposite.Two vibrating motors have been selected among the embodiment shown in Figure 1 for use.
Vibrating motor is positioned at identical, the switched in opposite of motor speed of sorting bed longitudinal centre line 8 both sides when work, referring to Fig. 3, its operation principle is as follows, motor eccentric force F
1, F
2Component F along Y-axis
1Y, F
2YCancel out each other, along X-direction component F
1X, F
2XForm vibration and make a concerted effort, drive the vibration of sorting bed.The mounting means that machine shaft is vertical with sorting bed compass screen surface has determined material along sorting bed length direction rectilinear motion, and promptly the material outbound course is consistent with direction of vibration, and the motion mode of material is for sliding.
Still referring to Fig. 1, Fig. 2, also comprise elastic parts 3 in the formation of the present utility model, elastic parts one end and sorting bed are hinged, and the other end and frame are hinged.Elastic parts plays the effect of main vibration spring, and elastic parts can be selected rubber spring or metal ring spring as required for use.
