Abstract
The utility model relates to material conveying technologies, particularly a material block proof device for a screw conveyer, which comprises a mandrel, a shell and screw blades, wherein, the screw blades are arranged outside the mandrel and in the shell. The utility model is characterized in that the screw blades comprise elastic and rigid blades, the elastic and rigid blades are connected through connectors, the rigid blades are connected with the mandrel, the cross section of the elastic blade forms an obtuse angle shape, and the outer edge of the elastic blade forms a tooth shape. The screw blades of the utility model adopt the combination of the rigid and elastic blades, the rigid blades are connected with the mandrel, and the elastic blades serve as the outer edge, which can effectively overcome the phenomenon of material block.
Description
(1) technical field
The utility model relates to the mass transport technology, relates in particular to conveyor screw anti-sticking materials device.
(2) background technology
Conveyor screw can be widely used in industries such as building materials, electric power, chemical industry, metallurgy, light industry, grain, is applicable to conveying powdered, granular and piece material.The conveying principle of conveyor screw mainly is the rotation by helicallobe, material pushing away forward along housing progressively.Conveyor screw is when convey materials, helicallobe rotates and housing is motionless, exist cliding friction between the outer rim of blade and the housing like this, in order to reduce friction, the normal certain interval that keeps between the outer rim of blade and the housing, the material of Shu Songing just is easy to enter the gap like this, because the gap along the circumferential direction usually is uneven in the equipment operation process, blade and housing generally are rigidity, if enter the material in gap certain rigidity and hardness are arranged also, along with the rotation of blade just is easy to cause the wedge shape jam.Especially when carrying block or during material that chiseling property of mill is bigger, conveyor screw gets stuck or stuck phenomenon sometimes, influence is normal carries operation, has also limited the field of application of conveyor screw.Chinese patent 89211621 discloses a kind of " the anti-jamming structure of conveyor screw ", it is that the blade-section on the local impeller under the loading hopper is excised, make its depth of blade be lower than depth of blade on other position spiral impellers,, solve stuck problem with this because local gap strengthens.This patent is only noticed the jam problem of inlet point, the jam phenomenon and the reason of other positions are not mentioned, moreover the increasing of local gap may aggravate the generation of jam phenomenon to the material of some granularity.
(3) summary of the invention
The utility model has overcome the defective of prior art, and a kind of conveyor screw anti-sticking materials device is provided.Helicallobe in this conveyor screw anti-sticking materials device adopts rigid blade and spring leaf to combine, and rigid blade is connected with mandrel, and spring leaf can effectively solve the generation of material jam phenomenon as outer rim.
The utility model is achieved in that a kind of conveyor screw anti-sticking materials device, comprise mandrel, housing, helicallobe, mandrel is equipped with helicallobe outward and places in the housing, it is characterized in that helicallobe comprises spring leaf and rigid blade, spring leaf is connected through connector with rigid blade, and rigid blade is connected with mandrel.
Above-mentioned conveyor screw anti-sticking materials device, the cross sectional shape of described spring leaf is an obtuse angle shape, the outer rim place has profile of tooth.
Principle of work of the present utility model be analysis cause conveyor screw material jam immediate cause be by blade, housing, material on a certain instantaneous basis that constitutes the rigidity wedge shape space, propose helicallobe and made the branch body structure, adopt rigid blade and spring leaf to combine, rigid blade is connected with mandrel, and spring leaf is as outer rim.When experience got stuck at work, spring leaf can be compressed by moment, and the profile of tooth of blade outer rim is taken out of with the turning handle blade outer rim of spiral and the material in the body clearance simultaneously, thereby efficiently solved the generation of material jam phenomenon.
(4) description of drawings
Fig. 1 is the utility model conveyor screw anti-sticking materials device structural representation, and Fig. 2 is the rotating blade structural representation.
Among the figure: 1 mandrel, 2 housings, 3 spring leafs, 4 materials, 5 profiles of tooth, 6 rigid blades, 7 connectors.
(5) specific embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, a kind of conveyor screw anti-sticking materials device, comprise mandrel 1, housing 2, helicallobe, mandrel 1 is equipped with helicallobe outward and places in the housing 2, helicallobe comprises spring leaf 3 and rigid blade 6, spring leaf 3 is connected through connector 7 with rigid blade 6, and rigid blade 6 is connected with mandrel 1.The cross sectional shape of spring leaf 3 is an obtuse angle shape, and the outer rim place has profile of tooth 5.
Claims (2)
1. conveyor screw anti-sticking materials device, comprise mandrel, housing, helicallobe, mandrel is equipped with helicallobe outward and places in the housing, it is characterized in that helicallobe comprises spring leaf and rigid blade, spring leaf is connected through connector with rigid blade, and rigid blade is connected with mandrel.
2. conveyor screw anti-sticking materials device according to claim 1, the cross sectional shape that it is characterized in that spring leaf is an obtuse angle shape, the outer rim place has profile of tooth.
