Abstract
The utility model discloses a spiral conveyor which comprises a shell, a conveying screw rod is arranged in the shell, a feeding inlet and a discharging outlet are formed in the shell, the conveying screw rod is connected with a first rotor which is provided with a second rotor in a matched mode, an air gap is formed between the first rotor and the second rotor, and an air gap cover used for adjusting the width of the air gap is arranged between the first rotor and the second rotor. The first rotor and the second rotor work in a cooperated mode through magnetic transmission, the spiral conveyor solves the problem that a traditional variable-frequency governor generates fatal influence due to the fact that dust conducts electricity and ventilation is affected in the conveying process of pulverized coal and other materials, and the service life of the spiral conveyor is prolonged.
Description
Technical field
The utility model relates to various powderies, particle even the mass transport technical field of viscosity, specifically a kind of conveyor screw.
Background technology
At present general conveyor screw mainly conveying powdered, granular, piece material is main, be not suitable for carrying material perishable, viscosity, easily caking or the material of bulk, because these materials are easily bonded at rotation thereupon on spiral, or in gangway, place produces putty phenomenon, to material conveying process, brings very large inconvenience.Due to when carrying dust-like material, easily control convenience (such as variable-frequency governor etc.) is exerted an influence, particularly in the material conveying process such as coal dust, on variable-frequency governor etc., can produce fatal impact, mainly contain dust conduction, impact ventilation etc., thereby cause the Frequent Troubles of conveyer; And for the large material of particle, easily overload, in the course of time, just cannot protect spiral, cause device damage serious, to safeguarding, bring adverse effect.
Summary of the invention
The utility model is not enough for prior art, and a kind of applicable dust-like mass transport and non-damageable conveyor screw are provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of conveyor screw, comprise housing, in described housing, be provided with conveying screw rod, on described housing, be provided with inlet point and discharging opening, described conveying screw rod is connected with the first rotor, described the first rotor matches is provided with the second rotor, between described the first rotor and the second rotor, there is air gap, between described the first rotor and described the second rotor, be provided with for regulating the air gap lid of described width of air gap.
In technique scheme, preferred, described housing two ends are provided with cleans inlet port and washing outlet.
In technique scheme, preferred, on described conveying screw rod, be provided with torque sensor.
In technique scheme, preferred, described the first rotor is permanent magnet rotor, and described the second rotor is copper rotor.
The utility model compared with prior art, there is following beneficial effect: the utility model adopts the mode cooperating of magnetic transmission by the first rotor and the second rotor, solve the fatal impact that traditional frequency conversion governor produces because of dust conduction, impact ventilation etc. in the material processes such as pulverized coal conveying, extended the service life of conveyor screw.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
the concrete structure of implementing
Below in conjunction with accompanying drawing and the concrete structure of implementing, the utility model is described in further detail: referring to Fig. 1, a kind of conveyor screw, comprise housing 1, in described housing 1, be provided with conveying screw rod 2, on described housing 1, be provided with inlet point 3 and discharging opening 4, described conveying screw rod 2 is connected with the first rotor 5, described the first rotor 5 matches is provided with the second rotor 6, between described the first rotor 5 and the second rotor 6, there is air gap, between described the first rotor 5 and described the second rotor 6, be provided with for regulating the air gap lid 7 of width of air gap.
Current most popular variable-frequency governor has been abandoned in speed governing of the present utility model, because in the material conveying process such as coal dust, on variable-frequency governor, can produce fatal impact, and major cause is dust conduction, impact ventilation etc.Here adopted the first rotor 5 and the second rotor 6 to coordinate transmission.The second rotor 6 is connected with motor shaft, and the first rotor 5 is connected with conveying screw rod 2.Between the first rotor 5 and the second rotor 6, have a. g., there is no the mechanical connection of transmitting torque, described the first rotor 5 is permanent magnet rotor, and described the second rotor 6 is copper rotor.When motor 11 rotates, on the copper ring of copper rotor, when the magnetic line of force of cutting permanent magnet, produce inducing eddy-current and application force between the magnetic field of inducing eddy-current and the magnetic field of permanent magnet has been realized the moment of torsion transmission between motor 11 and conveying screw rod 2.When air gap hour, the transmission capacity between the first rotor 5 and the second rotor 6 is strong, and on the contrary, when air gap is large, transmission capacity is little, by regulating air gap lid 7 to regulate size of gaps.
In addition, on described conveying screw rod 2, be provided with torque sensor 10, preferably, at the non-transmision end mounting torque sensor 10 of conveying screw rod 2, can carry out accurately to measure the torque suspension situation of conveying screw rod 2, to determine whether conveying screw rod 2 transships, whether need to clear up axle and the blade of conveying screw rod 2, and carry out again maintaining after need not waiting until motor 11 overloads, now mechanical damage will be more serious, can accomplish the pre-effect of safeguarding.
Set up self-cleaning passage, described housing 1 two ends are provided with cleans inlet port 8 and washing outlet 9, in the time of under normal circumstances, self-cleaning pathway closure, only have to torque sensor, report to the police for more than 10 time after or accumulated running time to just carrying out self-cleaning action afterwards.For different convey materials, self-cleaning adopts air-flow or liquid stream to carry out.
