Description
Technical field
The present invention relates to a kind of screening plant device, more particularly to the screening machine device of thermal power plant coal handling system.
Background technology
Screening machine is one of nucleus equipment of more industrial enterprise, can be widely applied to the industry such as coal of material thickness separation
Charcoal, generating, chemical industry, coking, steel, papermaking, grain, harbour etc..Screening plant is contacted for a long time with material in the process of running
Part will produce abrasion, this part is exactly mainly screen axis.Screen axis abrasion post gap changes, so as to cause to sieve thing
Material particle diameter produces change, working condition requirement is not reached after change of size, so, it is necessary to looking for a kind of structure quickly to change new and old sieve
Axle.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of structure that can quickly change screen axis.
The present invention is achieved through the following technical solutions：Screening machine screen axis transverse direction drawing structure, including screening machine, machine
Shell, screen axis, pulling hole, sealing flange, bearing block, detachable base, support frame；The position being engaged with screen axis on casing is provided with
Pulling hole, pulling hole is sealed by sealing flange, and pulling hole is divided into big pulling hole and small pulling hole, big pulling hole with diameter greater than sieve
The diameter of axle；For each screen axis, its one end is big pulling hole, and the other end is small pulling hole, on the housing of the same side
Big pulling hole is interspersed with small pulling hole；Support frame as described above is fixedly mounted on the side wall of casing, and detachable base is arranged on
On support frame, detachable base is pressed in the outside of sealing flange, and bearing block is arranged on detachable base by bolt.
The sealing flange is located on casing, and area is more than pulling hole and seals pulling hole.
Support frame as described above is located at detachable base and bearing block lower section, and end line is less than sealing flange, and the two on support frame
It is not attached to.
The detachable base is angle steel or i-beam structure.
Screening machine screen axis transverse direction drawing structure, also including adjustable motor base and reducing motor, the adjustable motor
Base is located at reducing motor lower section, and adjustable motor base middle part is provided with adjusting screw rod and adjusting nut.
The assembly and disassembly methods of screening machine screen axis transverse direction drawing structure, comprise the following steps：
S1：The bearing block for being intended to the old screen axis two ends of replacing is unloaded respectively；
S2：Detachable base below bearing block is unloaded；
S3：The sealing flange of casing both sides is unloaded；
S4：The upper lid of casing is opened, looks for a fulcrum rope to tie down old screen axis；
S5：Old screen axis is laterally moved out from big pulling hole；
S6：New screen axis is inserted into big pulling hole, the front end of new screen axis is tied down with rope, the new screen axis of transverse shifting is integrally inserted until screen axis
Enter in casing, the front end of new screen axis is fallen into the small pulling hole of the big pulling hole offside；
S7：Load onto the sealing flange on the outside of big pulling hole and small pulling hole；
S8：Detachable base is loaded onto, detachable base is pressed in the outside of sealing flange；
S9：Bearing block is arranged on detachable base and completes to fix.
Screening machine casing is made up of two parts, upper casing and lower casing, upper and lower enclosure to cuing open, when dismounting and overhaul is needed
Upper casing can be opened.Each pulling hole is formed with lower casing by upper casing to cuing open.Each pulling hole outside is all provided with casing
There is sealing flange, sealing flange is more than pulling hole.Screen axis is through the pulling hole and sealing flange on casing to bearing block, bearing block
Lower section is provided with detachable base, and detachable base has support frame.Detachable base top is connected with bearing block, bottom with branch
Support is connected, and when that need to change screen axis, can unload the sealing plate of casing both sides, bearing block, detachable base and laterally extract sieve out
The screen axis that axle more renews.
Described screening machine is not limited to roller picker, discaling roll sieve, sine screen, intersection sieve, step sieve etc..
1-5 pulling hole is additionally provided with below feed opening at lower casing, it with to cuing open, pulling hole is unrelated, but its size,
Function is consistent with pulling hole.
Described screen axis refers to that roller picker, discaling roll sieve, sine screen, intersection sieve, step sieve, impeller sieve etc. are circular configuration
Screen axis.
Described sealing flange is higher than support frame, and has gap.
Described motor is reducing motor, and its major function is to drive screen axis to rotate.
The pulling hole is located on casing, its point big pulling hole and small pulling hole, and pulling hole is by upper casing and lower casing pair
Cut open what is formed, also there is the fixation on lower casing positioned at charging aperture lower end to take out a hole.
Described sealing flange act as sealing pulling hole, and all of sealing flange is all higher than pulling hole, and sealing flange is not
Limit square, rectangle or circle.Sealing flange is connected with casing, and the power transmission shaft of screen axis passes through sealing flange.
Described takes out a hole position in casing both sides, and screen axis passes through both sides pulling hole, sealing flange to be more than pulling hole, Sealing Method
Orchid seals pulling hole on casing, and screen axis is connected through sealing flange with bearing axle center.Bearing, bearing block are provided with bearing block
Lower section is provided with detachable base, and detachable base lower section is provided with support frame.It is connected with bearing block on detachable base, lower and support
Frame is connected.
Described detachable base is not limited to I-steel and angle steel.Detachable base is provided with the hole being connected with bearing block
With the lower hole being connected with support frame.
Described upper casing is with lower casing to cuing open the second sets of plan dismantled when structure is for overhaul and change screen axis.
Described adjustable motor base, its structure is upper frame, middle part adjusting screw rod and adjusting nut, lower support,
The height of upper frame can be raised and lowered by the length for adjusting intermediate nut, to be easier to find between motor and screen axis
Horizontal concentric line.
The beneficial effects of the invention are as follows：
1）Complete to change by casing need not be opened after the abrasion of screening machine screen axis, the screen axis that will need to be only changed laterally is extracted out more
New screen axis is changed, the working strength of maintenance is alleviated, repair and maintenance time and human and material resources are saved.
2）It is by the consideration that size pulling hole is staggered：Gap very little between screen axis and screen axis, typically only 8mm
Left and right, and the diameter of big pulling hole have to be larger than the diameter of screen axis, therefore there is no sufficient space on chassis sidewall by pull
Big pulling hole is all made in hole, so pulling hole is made into small one and large one being uniform staggered with.
3）Why detachable base is set：In order to without prejudice to screen axis is extracted out from big pulling hole, the upper end line of support frame must
Sealing flange must be less than, in order to install bearing block, makes to be maintained on concentric line between each screen axis and motor, it is necessary to install detachable
Base pads are between bearing block and support frame.
