Abstract
A kind of blower mill, including striker wheel, casing, separator, bearing housing, motor slip coal channel, and improvements introduced is：Arrange in coal channel adjustable-angle and slip flitch slipping, flitch of sauntering is hinged on and slips on coal channel, flitch tilt adjustments screw rod of sauntering is set between side tube-wall in the case where slipping flitch and slipping coal channel, screw rod bearing pin is connected to and slips on flitch, slips mounting-fixing base on coal channel, moves and coordinate female adjusting sleeve in fixed seat, adjusting sleeve stretches out the part of fixed seat shaft end ring, there is spanner clamping face adjusting sleeve termination, has lock screw between adjusting sleeve and fixed seat, and screw rod is stretched in adjusting sleeve screwed hole.The positive effect of the present invention is：The flitch that slips set up can be in the case of non-stop-machine; turnover length that spanner adjust screw rod is adjusted with special outside; so as to change the angle for slipping flitch; change the position that raw coal enters striker wheel; and then change beater plate abration position; so that beater plate weares and teares evenly, increase beater plate service life.
Description
Technical field
The invention belongs to mechanical field, and in particular to it is large-scale with coal yard raw coal pulverizing blower mill.
Background technology
Blower mill is a kind of equipment being applied in the thermal power generation unit generated electricity by burning high-moisture brown coal, Jing
The raw coal Jing gates for crossing high-temperature flue gas preliminarily dried enter casing internal, strike are carried out to which by the striker wheel with beater plate broken
Broken, after the coal dust after crushing further is dried, separated device is separated, and qualified coal dust is admitted to boiler and is burnt.Originally
Raw coal be a little fixed position into falling into for coal pulverizer so that the abrasion of fixed position beater plate will be faster than other positions, make
It is serious into concentrated wear.Because blower mill belongs to high-speed rotation equipment, after strike prelaminar part may wear to a certain degree, just must
In time which must be changed, in case beater plate fracture, causes major accident after flying out.
The life-span of beater plate directly affects the time between overhauls(TBO) of blower mill and unit generation amount, is increasing the beater plate longevity
Once wear-resistant material had been used in life, had changed many means such as version, as high wear-resistant material cost performance is not high or knot
Structure is limited, to solving life problems effect on driving birds is not good.
The content of the invention
It is an object of the invention to provide a kind of blower mill, realizes that the raw coal into coal pulverizer is fallen in different time sections and beats
The working condition of striking wheel region diverse location so that beater plate even wearing, so as to increase the service life of beater plate.Overcome existing
There are technology above shortcomings.
The blower mill of the present invention includes the striker wheel with beater plate, and the outside striker wheel that surrounds is by helical design
Casing, the separator on casing top connect striker wheel and motor and support the bearing housing of striker wheel, the electricity for driving striker wheel to rotate
Machine, the closing for connecting coal spout and casing slip coal channel, slip coal channel entrance plate of the connection with closing and open function and stretch
Casing coupling.Improvements introduced is：Slip adjustable tilt angle is set in coal channel slip flitch, described flitch of sauntering enters coal end
The entrance for slipping coal channel is hinged on, in flitch is slipped, lower position and flitch of sauntering is set between side tube-wall under slipping coal channel is inclined
Rake angle adjusts screw rod, and there is the joint with horizontal pin shaft hole described screw rod upper end, and flitch of sauntering correspondence screw position installs screw rod
Connecting seat, has on screw rod connecting seat along the longitudinal strip flat of flitch of sauntering to pin shaft hole, passes through screw rod joint and screw rod to connect with bearing pin
Screw rod upper end is connected to and is slipped on flitch by the pin shaft hole on joint chair, and in the case where coal channel is slipped, side tube-wall is mounted across barrel fixed seat,
Move in fixed seat with the female adjusting sleeve of unification, adjusting sleeve is stretched out the end of fixed seat and is provided with back-up ring, stretches out fixation
There is spanner force surface the adjusting sleeve termination of seat, has lock screw between adjusting sleeve and fixed seat, and screw rod stretches into the screw thread of adjusting sleeve
Kong Zhong.It is the basic technical scheme of the present invention above.
To prevent from from fixed seat leaking out with adjusting sleeve gap, fixed seat stretch out slip outside coal channel termination assembling it is removable,
The fixed seat of dress and the seal closure in adjusting sleeve gap.
The positive effect of the present invention is：Set up slip flitch can in the case of non-stop-machine, outside use special regulation
Spanner adjusts the turnover length of screw rod, so as to change the angle for slipping flitch, changes the position that raw coal enters striker wheel, and then changes
Beater plate abration position so that beater plate weares and teares evenly, increases beater plate service life.
Description of the drawings
Fig. 1 is the entirety sectional view of the present invention.
Fig. 2 is that the present invention slips flitch adjustment mechanism position partial enlarged view.
Specific embodiment
Refering to Fig. 1, Fig. 2, a kind of blower mill of the present invention includes the striker wheel 3 with beater plate 6, and outside surrounds
Casing 2 of the striker wheel 3 by helical design, 2 top of casing are provided with for the detached separator 1 of thickness powder, connect striker wheel 3
With motor 5 and support the bearing housing 4 of striker wheel 3, the motor 5 for driving striker wheel 3 to rotate connects carrying for coal spout and casing 2
Scalable slips the plate telescopic joint 11 for slipping coal channel 10, slipping that 10 top of coal channel is connected with closing and unlatching of flitch 9.Slipping coal
A fixed seat 12 is welded on passage 10, is moved in fixed seat 12 with unification rotatable adjusting sleeve 13, under adjusting sleeve 13
Portion is equipped with shaft end ring 15, and screw rod 8 is connected in the screw rod mounting seat 18 for slipping 9 bottom of flitch by bearing pin 17, and is screw-inserted into
Inside adjusting sleeve 13, lock-screw 14 between adjusting sleeve 13 and fixed seat 12, is set, having in fixed seat 12 external mounting can demolition, installation
Seal closure 7, adjusting spanner 16 is used to rotate adjusting sleeve 13.
The present invention the course of work be：During use, first seal closure 7 and lock-screw 14 are pulled down, spanner 16 will be adjusted and pacified
13 end of adjusting sleeve is attached to, shake adjusts spanner 16 so that adjusting sleeve 13 drives screw rod 8 to move up and down, and screw rod 8 is promoted and slips flitch
9 to one suitable angle, that is, change the position that raw coal falls into striker wheel 3, so as to change the abration position of beater plate 6, extends
The use time of beater plate 6.13 position is covered after the completion of adjustment with 14 fixed adjustment of lock-screw, and takes away regulation spanner 16,
Install seal closure 7.
