Abstract
Disclosed is a permanent magnet motor local ventilator, which mainly solves the technical problems of bad work reliability, large volume, high cost and price, weak anti-EMI ability and the like of the conventional local ventilator using frequency converter to adjust speed. The technical scheme is that: The ventilator is a counter-rotating fan by connecting a current collector (1), a front silencer (2), a first-level fan (4), a counter-rotating second fan (5), and a rear silencer (6) in order, wherein the first-level fan (4) and the counter-rotating second level fan (5) are respectively composed by connecting a permanent magnet motor (7) and fan leaves, and the permanent magnet motor (7) is connected with an electronic pressure regulating and speed regulating controller in matching way. The motor electromagnetic field of the ventilator is made of permanent magnetic material, thereby having less consumed electricity; the ventilator has the characteristics of little power consumption, large torque, high efficiency, stable operation, improved system reliability, wide speed regulation rang, and reduced product cost; and the ventilator has a volume smaller than conventional explosion-preventing motor under the precondition of same power, which effectively increases the flow passage area.

Summary of the invention
The purpose of this invention is to provide and a kind ofly reduce product cost, improve system reliability, reduce the booster of permanent magnet motor that takes up room, increase work efficiency.
The technical solution adopted for the present invention to solve the technical problems is: it is to be connected successively by slip ring 1, premuffler 2, simple fan and rear muffler 6 to form local blower fan, described simple fan adopts magneto 7 and the fan blade formation that links, the connection that matches with electronic type variable voltage control controller of described magneto 7.
The present invention also can be by slip ring 1, premuffler 2, one-level blower fan 4, connect the counter-rotating fan that forms successively to revolving secondary blower fan 5 and rear muffler 6, the connection that matches with electronic type variable voltage control controller of described one-level blower fan 4 and adopt magneto 7 and the fan blade formation that links respectively, described magneto 7 to revolving secondary blower fan 5.
The magneto 7 of the present invention connection that matches with electronic type variable voltage control controller and intelligent switch respectively.Described intelligent switch is made of intelligent switch housing 11, intelligent switch terminal box 12 and Switch main body 14, and intelligent switch terminal box 12 is installed on the intelligent switch housing 11, and intelligent switch terminal box 12 is provided with cable leading device 13; Switch main body 14 is installed in the intelligent switch housing 11, Switch main body 14 is provided with communication module 9 and programmable logic controller (PLC) PLC10, intelligent switch operating grip 15 and man-machine dialog interface 16 are installed on the intelligent switch housing 11, and link with Switch main body 14, man-machine dialog interface 16 links by circuit and programmable logic controller (PLC) PLC10.Described Switch main body 14 be by isolate reverser, and joining with it electronic type comprehensive protection device 18 and vacuum contactor 17 constitute.
The present invention also can be provided with intrinsic safety I/O terminal box 8 in intelligent switch housing 11, intrinsic safety I/O terminal box 8 meets programmable logic controller (PLC) PLC10, described intrinsic safety I/O terminal box 8 is made of non-intrinsic safety tenminal block and intrinsic safety tenminal block more than 2 pairs, adopt photoelectric isolating circuit to link between the every pair of non-intrinsic safety tenminal block and the intrinsic safety tenminal block, described photoelectric isolating circuit is by the circuit that comprises that photo coupler, diode, electric capacity and resistance constitute.
The invention has the beneficial effects as follows: its motor-field is made of permanent-magnet material, thereby the electric energy that it is consumed is less; Compare with existing anti-explosion motor, it has, and power loss is little, moment of torsion is big, efficient is high; Operate steadily, system reliability is improved, and speed adjustable range is wide, product cost characteristics such as be reduced; Under the prerequisite of equal-wattage, the existing anti-explosion motor of its volume ratio is little, can increase Flow area effectively, thereby increases air quantity.It more is applicable to fan-type load, and it can satisfy the requirement of colliery fan condition fully.
