Abstract
The utility model relates to a floating and diameter-changeable type spiral conveyer, comprising a casing, a suspension bearing, a spiral mandrel and a transmission mechanism, wherein, the spiral mandrel is suspended and supported by the suspension bearing inside the casing. The utility model is characterized in that a diameter-changeable spiral mandrel (7) is adopted, namely, the diameter of a spiral blade at the connecting position of the suspension bearing and spiral mandrel is lager than the diameter of the spiral blade on the middle section of the spiral mandrel. A diameter-changeable casing (5) is arranged on the suspension bearing of the casing, and the diameter of the diameter-changeable casing (5) is corresponding to the diameter of the spiral blade on the suspension bearing. The suspension bearing and the supporting frame of the suspension bearing are in floating connection. The spiral mandrel is connected with the suspension bearing, a head bearing seat and a tail bearing seat by floating connecters. Owing to the characteristics, the utility model has the advantages of high starting rate, less maintenance cost, good energy-saving effect, etc. Compared with an existing spiral conveyer, the down time of the utility model is reduced by more than 80%. The mechanical energy consumption is low, so the power of motor of the utility model is reduced by 30% compared with the existing screw conveyor with the same specification and length.
Description
The utility model relates to conveying machinery, particularly a kind of unsteady Reducing screw conveyer of carrying materials such as cement that is applicable to.
Mainly there is the deficiency of the following aspects in conveyor screw of the prior art:
1. putty: generally all in 3～35M, because the spiral mandrel is short, the length of every joint is 1～2.5M to the length of conveyor screw of the prior art, and the longest is 3M.Per two joint places need hold with suspension bearing and hang, because the mandrel that uses is many, the amount of suspension bearing just increases, adding can not be continuous at suspension bearing place flight, form the interruption of about 150mm, cause material can not lean on spiral to carry continuously, but, cause material to pass through difficulty by heaping, being pressed through the suspension bearing place.Because each suspension bearing place all forms putty, the conveyor screw traffic capacity is reduced, also cause the suspension bearing place to wear and tear easily, the fault rate height, maintenance capacity is big, thereby increases cost of maintenance, has also reduced work efficiency.
2. get stuck: existing conveyor screw adopts flange form to be rigidly connected at each connecting portion, whole spiral mandrel can only rotate in housing, can not about and move up and down, owing to be mixed with hard thing in the material, when it moves between casing and the helicallobe, easily cause the card machine, make motor be burnt out or damage body etc.
3. energy consumption is big: the suspension bearing of existing conveyor screw is many, and employing is plain bearing.Owing to have the putty phenomenon at the bearing place, bearing can't be lubricated, and cause following watt of quick abrasion of suspension bearing, form helix core axle sag, whole spiral mandrel decentraction makes flight and casing friction, thereby has increased energy consumption.
The purpose of this utility model be to provide a kind of can avoid in the convey materials process, producing the putty and the phenomenon that gets stuck, can reduce maintenance load, increase work efficiency, can not cause the unsteady Reducing screw conveyer of excessive energy loss.
Above-mentioned purpose of the present utility model is to realize that by such technical scheme promptly a kind of unsteady Reducing screw conveyer comprises housing, suspension bearing, spiral mandrel and transmission device, wherein, and in housing, by suspension bearing suspension strut spiral mandrel; It is characterized in that: adopted the Reducing screw mandrel, promptly the diameter at the helicallobe of the relative spiral mandrel of the diameter interlude that is positioned at the helicallobe on the spiral mandrel of suspension bearing junction increases, and housing increases at suspension bearing place reducing, adapts with the diameter of herein helicallobe; Suspension bearing floats with its bracing frame and is connected, and the spiral mandrel is connected with suspension bearing, head shaft bearing, tail bearing seat by the attaching parts that floats.
The embodiment of the indefiniteness that above-mentioned purpose of the present utility model can provide by accompanying drawing further specifies.
The utility model has following accompanying drawing:
Accompanying drawing 1 is a structure cutaway view of the present utility model:
Accompanying drawing 2 is the local enlarged diagram of suspension bearing of the present utility model;
Accompanying drawing 3 is the birds-eye view of reducing housing of the present utility model;
Accompanying drawing 4 is the local amplification view of unsteady attaching parts of the present utility model.
Referring to accompanying drawing: comprise housing 4, suspension bearing 6, spiral mandrel and transmission device 1 among the figure, wherein, in housing, by suspension bearing suspension strut Reducing screw mandrel 7, this mandrel increases at the diameter of the helicallobe of the relative spiral mandrel of the diameter interlude of the helicallobe that is positioned at the suspension bearing junction, and adopt reducing housing 5 at the suspension bearing place, adapt with the diameter of herein helicallobe; Suspension bearing floats with its bracing frame and is connected, and the spiral mandrel is connected with suspension bearing, head shaft bearing 2, tail bearing seat 8 by the attaching parts that floats.The length of each reducing mandrel is 5～8M.In the present embodiment, the reducing mandrel is the tapered screw blade at the helicallobe that is positioned at the suspension bearing place, and other is straight helicallobe, and the diameter of tapered screw blade increases 30% than the diameter of straight helicallobe.Suspension bearing adopts antifriction-bearing box in the present embodiment, by its pipe link 14 and 13 unsteady connections of bracing frame, has setting nut 10 at the top of pipe link 14, between nut and the bracing frame, spherical washer 11 and taper faced washer 12 are installed, pipe link can be moved up and down and to each bearing oscillation certain angle.The adapter shaft 16 that the attaching parts that floats is through link slot 17 by connecting pin 15 and is positioned at it constitutes, wherein link slot 17 is fixed with mandrel, adapter shaft 16 is head, tail bearing seat rotating axis or for the suspension bearing axle, because described structure is floated adapter shaft 16 about can be in the gap of link slot 17.
Principle of work of the present utility model is such: material enters conveyer by inlet point 3, under the drive of mandrel helicallobe, material is pushed ahead, through the suspension bearing place time, since herein increased helicallobe diameter, change its shape, and the corresponding increase of housing herein can be passed through material smoothly, is sent by discharging opening 9 at last.
The utility model is owing to described structure has following advantage:
1. owing to adopted the mandrel of reducing and the housing of reducing, both reduced the phenomenon of putty, The wearing and tearing to hanger bearing have been reduced again.
2 adopt floating connecting structure, and the conveyor screw mandrel is in the certain limit in housing Free rotation state, when hard thing passed through, the spiral mandrel can automatically move up and down and keep away Allow and it does not got stuck, avoided to motor burn out and to the damage of body.
3. owing to increased the length of mandrel, thereby the quantity of suspension bearing be can reduce, manufacturing cost and maintenance cost reduced; And suspension bearing adopts antifriction-bearing box, and leak tightness is good, has reduced mechanical wear, has also reduced energy consumption.
In a word, the utility model has advantages such as the rate of starting height, service expenditure are few, good energy-conserving effect owing to described feature, and its downtime is compared with existing conveyor screw and reduces more than 80%; Because mechanical energy consumption is little, thereby than the power of motor minimizing 30% of the conveyor screw of existing same specification length.
The utility model is particularly suitable for uses such as various manufacture of cement producer, building materials manufacturer.
