Description
Technical field
The utility model relates to hammer mill field, especially a kind of hammer mill of self-cleaning.
Background technique
In order to improve the thermal stability of coal, need to carry out raw coal into the particle for being broken into uniform particle size, hammer mill is
Industrial common crushing device.When the hammer mill of the prior art is crushed coal cinder, since supplied materials is usually from wet feed, when being crushed
Wet feed particle usually from adherency blocking and be trapped in crusher chamber, this just will increase the tup of hammer mill and the mill of liner plate
Damage increases maintenance burden.
Summary of the invention
The purpose of this utility model, which is that, overcomes above-mentioned deficiency, provides a kind of hammer mill of self-cleaning.
In order to achieve the above objectives, the utility model is implemented according to following technical scheme:
A kind of hammer mill of self-cleaning, including pedestal, shell, crusher chamber, shafting assembly, interior lining panel, interior lining panel are solid
It is scheduled on broken cavity wall, shafting assembly is rotatably connected in crusher chamber, and shafting assembly includes belt pulley, shaft, rotor disk, turntable
Spacer, tup pin shaft, tup, rotor disk, being connected by key for turntable spacer interval are fixed in shaft, and tup passes through hammer shaft
On rotor disk, shell is fixed on the base pin hinge connection, and shaft is fixed on the base by bearing, bearing block, described broken
Chamber includes upper crusher chamber and lower crusher chamber, shafting assembly it is opposite be provided with shafting assembly and two sets of shafting assembly lower, upper axis
Be assembly and lower shafting shaft rotation direction it is opposite；Gas path pipe is provided in the spindle central, shaft side wall is provided with
Stomata, stomata are connected with gas path pipe, and stomata is staggered between rotor disk, and turntable spacer is arranged with respect to the position of stomata
There is stomata slot, shaft is provided with rotary joint relative to the side of fast pulley, and rotary joint includes connector rotor and connector
Stator, connector rotor are fixedly connected with shaft by flange, and connector stator is fixed on the base, and connector stator exterior is communicated with height
Press air.
Further, the stomata staggered helical is arranged on shaft side wall.The stress for reducing shaft is concentrated, and shaft is prevented
Fracture.
Compared with prior art, the pressure-air being passed through by rotary joint of the utility model, by gas path pipe, gas
Hole, stomata slot purge the crusher in crusher using the rotation of shaft, wet feed are prevented to be bonded in liner plate, rotor
On disk, blocking is reduced；Twin-stage is broken to increase crushing effect, the line of the rotating shaft core of shafting assembly and lower shafting and horizontal plane
Angle is 48 °, and wet feed can be crushed thoroughly, will not be blocked, and avoid burning out motor, influences to produce；Hammering, broken cinder
Granularity meets the requirement of broken rear powdery coal grain compacting moulded coal, increases the stability of coal combustion less than 3 millimeters.The utility model
Have the beneficial effect that crusher crushing effect is good, wet feed can be also crushed, broken wet feed will not adhere to blocking and be trapped in brokenly
Broken chamber, structure is simple, and excellent self-cleaning effect is good, reduces the workload of maintenance.
