Abstract
The utility model relates to a blocking prevention type star unloading device. The blocking prevention type star unloading device is composed of a drive device, a transmission device, a housing and a transmission shaft, wherein a star impeller is arranged on the transmission shaft, a plurality of blades are evenly distributed on the outer circumference of the star impeller, each blade is divided into an upper portion and a lower portion, and the upper portion and the lower portion of each blade are movably connected through a spring and a pin shaft. The blocking prevention type star unloading device is smooth and reliable in work, even and accurate in unloading, optimized in structure, small in size, good in air locking performance, convenient to maintain and long in use life, can not block materials, and solves the problems that anomalous sundries block the impeller, the impeller can not work, and a device is damaged.
Description
Technical field
The utility model relates to a kind of blocking preventing formula star-like discharging device, belongs to a kind of material transfer equipment.
Background technology
Common discharger and star-like discharging device be widely used in the industries such as chemical industry, metallurgy, mine, dedusting, environmental protection, electric power, grain in discharge system, but its shortcoming is in the time having special-shaped foreign material to fall into, the parking that is stuck of star impeller, the lighter's star blade damages, and severe one actuating device is damaged.Not only need manpower and materials to keep in repair, the stopping production of manufacturing line simultaneously also can bring serious economic loss.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of blocking preventing formula star-like discharging device, this blocking preventing formula star-like discharging device stable working is reliable, discharging evenly accurately, structure optimization, volume is little, air locking can be good, do not get stuck, easy to maintenance, long service life, and solved special-shaped foreign material and block impeller, can not work and the problem of damage equipment.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of blocking preventing formula star-like discharging device, mainly formed by actuating device, driving device, housing and transmission shaft, on transmission shaft, be provided with star impeller, be provided with several well-distributed blades at the excircle of star impeller; Blade is split into upper and lower two parts, and is flexibly connected by spring and bearing pin.
Described housing top is material inlet, is provided with spiral guide roller setting up and down at the medial extremity of housing, and the rotation direction of two spiral guide rollers is contrary.
Described each blade and the axis of transmission shaft are an angle.
This blocking preventing formula star-like discharging device adopts folding blade construction, can ensure that, in the situation of feed blocking, blade can bend, thereby protect blade can not damage, and has avoided stuck phenomenon simultaneously.
Be provided with two spiral guide rollers at material inlet medial extremity, two spiral guide roller rotation directions are contrary, the special-shaped material that this structure can enter material mouth turns to and is pressed in the hopper of star impeller by spiral guide roller, thereby the phenomenon of having avoided material to be stuck in housing entrance higher than blade occurs.
Brief description of the drawings
Fig. 1 is the front view of blocking preventing formula star-like discharging device.
Fig. 2 is the right elevation of blocking preventing formula star-like discharging device.
Fig. 3 is the structural representation of star impeller and blade.
Detailed description of the invention
Shown in Fig. 1 to Fig. 3, a kind of blocking preventing formula star-like discharging device, is mainly made up of actuating device 5, driving device 1, housing 2 and transmission shaft 3, is provided with star impeller 9 on transmission shaft 3, is provided with several well-distributed blades 8 at the excircle of star impeller 9; Blade 8 is split into upper and lower two parts, and is flexibly connected by spring 4 and bearing pin.
Described housing 2 tops are material inlet, and the rotation direction that is provided with 7, two spiral guide rollers 7 of spiral guide roller setting up and down at the medial extremity of housing is contrary.
Described each blade 8 is an angle with the axis of transmission shaft 3, and this angle is directly proportional to the diameter of star impeller 9, thereby guarantee material can be derived smoothly.
Its principle of work is: actuating device 5 mouths are connected with transmission shaft 3, drive star impeller 9 to rotate by transmission shaft 3, blade 8 is in tilted layout circle distribution on star impeller, two spiral guide roller 7 rotation directions are contrary, when its operation, material falls into rotation lock gas discharging in star impeller hopper, in the time that special-shaped foreign material fall into, foreign material are turned to and are pressed in the hopper of elasticity bending star impeller by two spiral guide rollers 7, ensure that star impeller is not by jam.
