Description
Technical field
The present invention relates to fire-proof motor, the mainly explosion separation motor in fire-proof motor.
Background technology
Explosion separation motor is by there may be the electronic unit of electric spark, electric arc and dangerous temperature and surrounding are explosive in motor
The mixture of gas separates.But this shell is not sealing, the explosive gas mixture of surrounding can pass through shell
Each several part composition surface gap enter motor internal.When being contacted with Ignition sources such as the spark in shell, electric arc, dangerous high temperature just
It may explode, at this moment the flameproof enclosure of motor not only will not be damaged or deformed, and explosive flame or hot gases pass through
When composition surface gap is spread out of, the explosive gas mixture for the surrounding that can not ignite.The flameproof joint of existing explosion separation motor
With there is no cooling device mostly on flame proof gap；Either cooling devcie of motor is in motor internal, it is impossible to effectively reduces discharge
The temperature of electric spark and electric arc, a certain degree of potential safety hazard be present.
The content of the invention
In order to overcome disadvantages mentioned above, the present invention provides a kind of explosion separation structure of explosion separation motor, including support, the first end cap,
Second end cap, bearing, clutch shaft bearing lid, second bearing lid and cooling device；First end cap and second end cap difference
Installed in the both ends of the support；The bearing is fixed on first end cap and second end cap；The clutch shaft bearing
Lid is fixed on first cover internal, and the second bearing lid is fixed on the inside of second end cap；The clutch shaft bearing
Lid and the second bearing have covered hole and have been fixed on the bearing；The support and the first end cap-shaped are between the first flame proof
Gap, the support and the second end cap form the second flame proof gap；The bearing and the first end cap-shaped into the 3rd flame proof gap,
The bearing forms the 4th flame proof gap with second end cap；The clutch shaft bearing lid and the bearing are formed between the 5th flame proof
Gap；The second bearing lid forms the 6th flame proof gap with the bearing；The cooling device includes several cooler bins and storage
Water tank；Cooler bin is provided with outside the first flame proof gap, the second flame proof gap, the 3rd flame proof gap and the 4th flame proof gap；
Each described cooler bin is arranged on the outside in flame proof gap.
Further, the cooler bin is to be connected with each other, and is connected to form circulation with the storage tank.
Further, the cooler bin is made of polyamides fat material.
The explosion separation structure of explosion separation motor provided by the invention, adds cooling device, can effectively reduce along between flame proof
The electric arc of gap discharge or the temperature of electric spark, reduce the possibility that gas is ignited around igniting, improve safety coefficient；Can also
Motor internal temperature is reduced to a certain extent；Using polyamides fat material, there is good insulating properties, can prevent from leaking electricity；Machinery
Intensity is high, high temperature resistant, wear-resistant.
Brief description of the drawings
Fig. 1 is the side, sectional structural representation of explosion separation structure provided by the invention.
Embodiment
The present invention is described in further details below in conjunction with the drawings and specific embodiments.
As shown in figure 1, the explosion separation structure of explosion separation motor provided by the invention, including support 100, the first end cap 200, second
End cap 300, bearing 400, clutch shaft bearing lid 500, second bearing lid 600 and cooling device；First end cap 200 and described
Two end caps 300 are separately mounted to the both ends of the support 100；The bearing 400 is fixed on first end cap 200 and described
On two end caps 300；The clutch shaft bearing lid 500 is fixed on inside first end cap 200, and the second bearing lid 600 is fixed
In the inside of second end cap 300；There is hole to fix the axle on the clutch shaft bearing lid 500 and the second bearing lid 600
Hold 400；The support 100 forms the first flame proof with first end cap 200 and connects gap 110, the end cap of support 100 and second
300 form the second flame proof gap 120；The bearing 400 forms the 3rd flame proof gap 130, the axle with first end cap 200
Hold 400 and form the 4th flame proof gap 140 with second end cap 300；The clutch shaft bearing lid 500 is formed with the bearing 400
5th flame proof gap 150；The second bearing lid 600 forms the 6th flame proof gap 160 with the bearing 400；The cooling dress
Put including several cooler bins 710 and storage tank 720；The first flame proof gap 110, the second flame proof gap 120, the 3rd flame proof
Gap 130 and the 4th is provided with cooler bin 710 outside flame proof gap 140；Each described cooler bin 710 is arranged between the flame proof
The outside of gap.
The cooler bin 710 is to be connected with each other, and is connected with the storage tank 720, forms circulation.The cooler bin
710 be using made of polyamides fat material.After motor brings into operation, electronic unit probably produces electric arc or electricity fire
Flower, motor flameproof principle is thoroughly done away with, caused electric arc and electric spark are discharged along flame proof gap, and cooler bin is provided with outside flame proof gap
The electric arc of discharge or the temperature of electric spark can be reduced, the possibility that outside flammable explosive gas is ignited is reduced, improves peace
Overall coefficient.
Preferred embodiments of the present invention are these are only, therefore the scope that the present invention is implemented can not be limited according to this, i.e., according to the present invention
The equivalence changes and decoration that description is made, it should all belong in the range of present invention covering.
