nullDescribed blower fan case includes outer casing 1a、Interior vestlet 1b，Case sealing ring is set in outside outer casing，Shell air channel is in interior vestlet，Outer casing is coaxial with interior vestlet，The peripheral channel 13 of tubulose is formed between outer casing and interior vestlet，Peripheral channel is inner to be connected with silo inside，Peripheral channel outer end connects with the silo external world，Peripheral channel outer end is provided with ring sealing plate 14，Ring sealing plate will cut off between peripheral channel outer end and the silo external world，Ring sealing plate is provided with some plate air vents 141、Some hinged with ring sealing plate and for closing or the interior air door 142 of open plate air vent，Plate air vent and interior air door one_to_one corresponding，Interior air door is provided with the roof door spring 143 for interior air door withstands on closed mode，Roof door spring one end is connected with outer casing，Outer casing is provided with the main shutter door 1c of casing for closing or open blower fan case air outlet、Keeper for the main shutter door of locking，Between interior vestlet and the main shutter door of casing, there is overdose space；The main shutter door of casing be provided with some for backing down interior air door so that the door push rod 1d that opens of plate air vent, door push rod and interior air door one_to_one corresponding；When the main shutter door of casing completely closes, door push rod backs down air door in correspondence；When the main shutter door of casing fully opens, door push rod with corresponding in air door depart from.Described main shutter door is provided with the heat sink strip 1e of the main shutter door of multiple traverse, heat sink strip end in overdose space, the heat sink strip other end is in outside blower fan case.
Peripheral channel is a passage that can realize auto switching: when the main shutter door of casing is opened, motor, impeller normal operation are to when being aerated in silo dispelling the heat, what now carry out is " outer circulation ", namely the air outside silo externally enters from silo, (interior air door remains turned-off under the effect of roof door spring, and peripheral channel is blocked) is discharged from shell air channel again after being piled by grain.When the main shutter door of casing closes (now can use the bolt lock main shutter door of stop machine shell), now door push rod backs down air door in correspondence (roof door spring is also further compressed), connects between peripheral channel outer end and overdose space, motor, impeller normal operation, then air can enter shell air channel air intake (i.e. motor case air intake) in silo and enter into peripheral channel outer end then through shell duct exhaust air end, each plate air vent subsequently, finally return to silo from peripheral channel the inner again, thus defining " internal recycle ".Outer moisture is relatively big or dust is more be difficult to ensure airflow cleans by common filtration time, just can adopt the mode that internal recycle cools down, air-flow is in silo, be circulated in the internal and external circumferential passage of shell air channel, take away the heat of grain heap, and air-flow is when flowing through overdose space, carrying out heat exchange with heat sink strip, heat is delivered to outside silo by heat sink strip, thus internal recycle cooling can effectively be realized.
Again or when needing to carry out fumigant insect killing, it is also very suitable for using internal recycle.Medicament along with air-flow is in silo, be circulated in the internal and external circumferential passage of shell air channel, can be effectively reduced waste, promotes effect.Additionally, realize the switching of inner-outer circulation by switching the main shutter door of casing, it is possible to when thoroughly avoiding internal recycle, the problem of the internal recycle poor effect having too much gas exchange to cause with the external world because forgetting to turn off main shutter door.
nullMultiple heat radiation regulating part it is provided with in described shell air channel，Each heat radiation regulating part is uniformly distributed along blower fan case circumference，Heat radiation regulating part includes heat radiation and regulates batten 51、Transition connecting rod 52、The guide thimble 53 that one end open and the other end are closed、It is in the regulating piston 531 in guide thimble、It is in the adjustment spring 532 in guide thimble，Guide thimble opening is through interior vestlet and connects with shell air channel，Dispel the heat in regulating part at one: it is hinged with interior vestlet away from one end of cooling jacket that heat radiation regulates batten，It is hinged near one end of one end of cooling jacket Yu transition connecting rod that heat radiation regulates batten，The other end of transition connecting rod passes the opening of guide thimble and hinged with regulating piston，Regulating piston is between adjustment spring and transition connecting rod，Regulating piston and guide thimble are slidably connected and the slidably direction of regulating piston is axially in parallel with guide thimble，Regulate spring one end and connect the blind end of guide thimble，Regulate the spring other end and connect regulating piston.As previously mentioned, the air-flow flowing through motor is relatively fewer, it is easily caused the heat radiation deficiency of motor, accumulated heat, especially motor speed (relatively) is all the more so (during motor speed height time not high, integrated air flow is big, flowing through what the throughput of motor still can be protected, now radiating effect is preferably).And if reduction air channel bore is to promote ratio and the flow velocity flowing through motor airflow, then when needs Wind Volume (now motor is high rotating speed), it is easy for causing that air-flow 'go'gage is not enough.And in this programme, a circle heat radiation regulates batten and encircled a city in one " wind gathering air channel ", between adjacent heat radiation adjustable plate, then form wind gap.Motor speed uprises, air velocity becomes anxious, airflow passes respectively dispels the heat adjustment batten near the plate face of fan shroud columella line, and press thermal conditioning batten and be displaced outwardly, heat radiation adjustable plate rotates along pin joint, and press regulating piston by transition connecting rod and slide in and out (in guide thimble slide), regulating spring pressurized, each heat radiation adjustable plate is (air circulation bore increases relatively) in " opening " state.Now except there being enough air-flows to flow through in cooling jacket, all the other air-flows can also flow through between cooling jacket and shell wind path wall, can effectively ensure that smoothness that air-flow flows through and possess suitable ventilation bore (after heat radiation adjustable plate starts to be promoted outer shifting by air-flow, motor speed is more high, ventilation bore can become more big, so possessing adaptivity).
Described heat radiation regulates batten and is provided with heat conduction bonding jumper 511 near one end of cooling jacket, and cooling jacket lateral wall is provided with some film traps, heat conduction bonding jumper and film trap one_to_one corresponding, and heat conduction bonding jumper is in the film trap of correspondence and contacts with cooling jacket.When motor speed is relatively low, and air-flow velocity is not reaching to significantly high, now also it is not enough to overcome the power regulating spring to allow heat radiation adjustable plate be turned out, so can ensure wind gathering effect, more air is allowed to flow through from middle part such that it is able to have more air to flow through motor, ensure motor radiating.And, heat radiation is regulated batten and is connected as a single entity by heat conduction bonding jumper and temporary transient cooling jacket, be equivalent to effectively extend the heat radiation length of cooling jacket, the heat produced on motor can pass to cooling jacket, heat conduction bonding jumper, and heat conduction bonding jumper can touch the air of a large amount of flowing, it is thus possible to realize heat exchange faster and better, play the effect that motor is dispelled the heat, can service life (heat radiation adjustable plate, heat conduction bonding jumper copper or other Heat Conduction Material can be adopted to make) of effective guarantee motor.
