Abstract
The utility model discloses a spiral transport machine, which is used for the transportation of coal dust which have a high temperature in the power generating plant and other powdery or granular materials. The utility model adopts a circular sectionalized casing, and the sections are connected via a base, and the base is integrated with a bearing seat as a whole; the bottom panel of the spiral transport machine is fixed with the base, and the middle between the housing and the base adopts a sealing packing pressurization connection mode. The utility model can improve the rigidity of the bearing seat and the processing performance, the concentricity of a spiral body is improved, the influence of the housing deformation on the base and the bearing seat is eliminated, and therefore, the operating performance and service life of the spiral transport machine are improved.
Description
The utility model is a kind of conveying machinery, particularly a kind ofly is used for conveyor screw conveying powdered and the granule bulk material.
What the conveyor screw in the general-duty conveyor screw adopted at present is hanging bearing, and bearing seat is to be suspended in cover top portion by bolt, so rigidity is bad, unbalance stress, and fracture easily.Be difficult to simultaneously guarantee spirochetal concentricity, it is dumb to cause conveyor screw to rotate, and easily blocks, even damages.Because the body of conveyor screw is longer, and single-piece shell and support employing are fixedly connected, so shell produces very big influence because of the expansion formation accumulated deformation that temperature build-up produces to support and bearing seat.50 meters long conveyers for example, in use since temperature rise influence extending 30～40 millimeters of its length, thereby cause holding-down bolt to cut off, hanging bearing such as blocks at phenomenon.What the general-duty conveyor screw adopted now is the U-shaped shell that steel plate is made, leak tightness is very poor, and it is serious to leak powder, and working environment is polluted, the unreasonable part that exists is gone up in said structure design, to conveyor screw continue to use and enlarge production all bring very big difficulty.
The purpose of this utility model provides a kind of improved New screw conveyer, the good rigidly of its bearing seat, spirochetal concentricity height, and rotate flexibly, reliable operation, casing sealing is good, can reduce the pollution to working environment, can eliminate simultaneously because of the shell temperature distortion to influence that support and bearing seat produced.
The purpose of this utility model is achieved in that circular housing adopts sectional type, between link with support, bearing seat and support are one, employing casting or welded-steel plate construction all can.The base plate of support has bolt hole, can directly connect with basic fixed.Adopt gland packing to add the inserting mode of differential between shell and the support, middle coupling spindle is to be assembled in the bearing seat, and plunging joint is equipped with at its coupling spindle two ends, links with spirochetal center shaft.
The utility model is owing to adopted the support that directly connects with basic fixed to reach and support is the bearing seat of one, so the good rigidly of bearing seat, and good processability improves spirochetal concentricity greatly.Owing to adopt circular housing.And with support between adopt gland packing to add differential inserting mode connect, promptly played sealing function, made support and bearing seat not be subjected to the influence of casing deformation simultaneously, therefore reduced pollution environment, and bearing is rotated flexibly, prevented the phenomenon that holding-down bolt is cut off.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the overall structure scheme drawing of present general-duty conveyor screw.
Fig. 2 is the overall structure scheme drawing of a kind of specific embodiment of the utility model.
Fig. 3 is the enlarged view of point of attachment among Fig. 2.
With reference to accompanying drawing 1, what visible general-duty conveyor screw now adopted is unsplit casing 1 and suspension type bearing seat 2, the irrationality of this structure, determine that its bearing seat rigidity is low, processing characteristics is bad, and conveyor screw 3 rotates dumb, occurs stuck and holding-down bolt such as is cut off at phenomenon.
With reference to accompanying drawing 2～3, the shell 4 of present embodiment is circular sectional type, and each section end and support 5 link.Support 5 is an one with bearing seat 6, adopts cast iron quality, the one-step casting moulding.The base plate of support 5 is fixed with holding-down bolt 8 and ground, to reduce the vibration of support 5.Connecting between support 5 and the shell 4 adopts asbestos rope 11 as gland packing, compresses with differential 12, and differential 12 is made up of pressure ring and flange.Flange links with bolt 13 and support 5.As long as bolt 13 is screwed, can asbestos rope 11 be compressed by pressure ring, both played sealing function, play anastomosis again with shell 4.Because shell 4 adopts this inserting mode with support 5.So the distortion that shell 4 produces owing to being heated in the working process just can not have influence on support 5 and bearing seat 6.Coupling spindle system in the middle of in bearing seat, being assembled with, it comprises bearing 10 and coupling spindle 9, and the transversal surface at the two ends of coupling spindle 9 is square, pegs graft with plunging joint 8, and plunging joint 8 connects with bolt with the flange of conveyor screw 7 center axle heads.For preventing that dust from entering bearing 10, in the both sides of bearing 10 end cap 14 is housed all, and seal ring is housed.
The utility model is suitable for carrying granule and granular material, is specially adapted to the higher coal dust of thermal power plant delivery temperature.
Claims (3)
1, a kind of conveyor screw, it comprises conveyor screw, shell, bearing seat, support and middle coupling spindle system, it is characterized in that bearing seat and support are one, can directly connect with basic fixed, shell adopts circular sectional type, adopts gland packing to add the inserting mode of differential between its end and the support.
2, conveyor screw according to claim 1 is characterized in that support and bearing seat can be casting or steel plate welding fabrication.
