Abstract
The utility model discloses a rotational flow device used in a wet coal dressing process. The rotational flow device comprises a first-section cyclone, a second-section cyclone and a slurry pump fixedly connected with a feed end of the first-section cyclone. The rotational flow device is characterized by further comprising a feed motor, wherein the slurry pump can be connected with the feed motor by means of a belt transmission mechanism. The rotational flow device has the advantages that a support used for connecting the slurry pump and the feed motor is eliminated, the size of the integral rotational flow device is reduced, the rotational flow device can be conveniently matched with other coal dressing equipment to be used, meanwhile the slurry pump and the feed motor are connected through the belt transmission mechanism, various damping conditions of the slurry pump can be adapted to, and damage to the feed motor when the damping power of the slurry pump is larger than the output rating of the feed motor is avoided; and due to the fact that cylindrical roller bearings are arranged between two ends of a rotating shaft of the slurry pump and a pump shell, the rotating shaft is in a two-end support structure, stability of the rotating shaft is increased, excessive abrasion to the cantilever beam type rotating shaft in the using process is avoided, and service life of the slurry pump is prolonged.
Description
Technical field
The utility model relates to a kind of wet coal preparation special equipment technical field.
Background technology
Dense-medium separation is the widely used a kind of cleaned coal method for separating of coal separation industry, the swirl-flow devices that uses in the assorting room comprises one section cyclone, two sections cyclones and slag stock pump, the slag stock pump is fixedly connected with one section cyclone, and the direct raw coal inlet with one section cyclone of the discharging opening of slag stock pump is connected and sealed; The discharging opening of slag stock pump is connected and sealed by the raw coal inlet of flange and one section cyclone; The charging motor and the slag stock pump that are used for driving slag stock pump are fixed at same support, and charging motor output end and slag stock pump input are rigidly connected by shaft coupling, although save to a certain extent conveying pipeline length, reduce supporting cost, still, because support is longer, virtually increase the swirl-flow devices volume, simultaneously because being rigidly connected between charging motor and the slag stock pump when the damping of slag stock pump is larger, easily damages the charging motor; More in addition, wherein employed slag stock pump adopts an end fixed form, and its main shaft is a cantilever beam structure, less stable, and the life-span is short.
The utility model content
Technical problem to be solved in the utility model provides the swirl-flow devices that uses in a kind of wet coal preparation process; by flexibly connecting adopting between slag stock pump and the charging motor; save the support that connects charging motor and slag stock pump; reduced volume; and flexibly connect and can effectively protect the charging motor, prolong its service life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the swirl-flow devices that uses in a kind of wet coal preparation process comprises one section cyclone and two sections cyclones and the slag stock pump that is fixedly connected with one section cyclone feed end; Its key improvements is: also comprise the charging motor, described slag stock pump is connected with described charging motor by means of belt gear.
Described slag stock pump comprises pump case, blade and rotating shaft; Bearing all is set between described rotating shaft terminal and the pump case.
Described bearing is cylinder roller bearing.
The beneficial effect that adopts technique scheme to produce is: cancellation is used for connecting the support of slag stock pump and charging motor, dwindle the integral cyclone device volume, convenient and other cleaning units support the use, to adopt belt gear to be connected between slag stock pump and the charging motor simultaneously, can adapt to the various damping situations of slag stock pump, damage the charging motor when preventing because of slag stock pump Damping Power greater than charging motor rated output power; The utility model is also by all arranging cylinder roller bearing between slag stock pump rotating shaft terminal and pump case, make rotating shaft become the two end supports structure, increase its stability, avoid in use excessive wear of beam type rotating shaft, prolong slag stock pump service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the slag stock pump structural representation that uses in the utility model;
In the accompanying drawings: 1, charging motor; 2, slag stock pump; 2-1, rotating shaft; 2-2, cylinder roller bearing; 2-3, pump case; 3, one section cyclone; 4, two sections cyclones.
The specific embodiment
The swirl-flow devices that uses in a kind of wet coal preparation process of the utility model, existing swirl-flow devices comprise one section cyclone 3 and two sections cyclones 4 and the slag stock pump 2 that is fixedly connected with one section cyclone 3 feed end; Its key improvements is: also comprise charging motor 1, described slag stock pump 2 is connected with described charging motor 1 by means of belt gear.Be rigidly connected by means of shaft coupling between the charging motor of existing swirl-flow devices and the slag stock pump, and charging motor and slag stock pump all are fixed on the same support, support is longer, the integral cyclone device volume is larger, be not easy to support the use with other cleaning units, the utility model is by adopting belt gear to connect charging motor output end and slag stock pump input, both needn't coaxially arrange on the one hand, also need not to use than long stent, the charging motor can be directly installed on other equipment supporters and get final product, dwindle the integral cyclone device volume, on the other hand, belt gear is for flexibly connecting, when slag stock pump Damping Power during greater than the charging motor rated power, belt gear produces and to skid, and prevents the operation of charging motor overload, prolongs charging motor service life.
Described slag stock pump 2 comprises pump case 2-3, blade and rotating shaft 2-1; Between described rotating shaft 2-1 two ends and the pump case 2-3 bearing is set all, described bearing is cylinder roller bearing 2-2, between the rotating shaft input of existing slag stock pump and the pump case of slag stock pump cylinder roller bearing is set, form cantilever beam structure, in use because blade is concentrated stressed, cylinder roller bearing is subjected to axial force and radial load, be difficult for sealing, service life is shorter, and the utility model at rotating shaft terminal all and between the pump case cylinder roller bearing is set, increase rotating shaft stability, prolong its service life.
Claims (3)
