Abstract
The utility model provides a kind of full-automatic unpacking unloader cutter installation axle, including the cutter fixed axostyle for installing cutter, cutter fixed axostyle one end is equipped with driving motor, cutter fixed axostyle is made of the fixed shaft part in left side, the fixed shaft part in right side and intermediate shaft part, the fixed shaft part in left side is connected on unpacking unloader casing by bearing assembly, and the fixed shaft part in right side is connected on casing by mounting assembly；Cutter is fixedly installed on intermediate shaft part, intermediate shaft part both ends are affixed with the fixed shaft part in left side, the fixed shaft part in right side respectively by shaft coupling, after the completion of the utility model transformation, replacement cutter only needs to be removed intermediate shaft part, effectively reduces maintenance duration.
Description
Technical field
The utility model belongs to thermal power plant production urea supply equipment technical field, and in particular to full-automatic unpacking
The cutter of unloader installs axle construction.
Background technique
Denitration process is done to coal-fired flue-gas in thermal power plant, uses urea as reducing agent.The full-automatic unpacking discharging of urea
Machine is that urea transports supply arrangement in unit, and urea unpacking discharging uses full-automatic unpacking unloader, since routine use is frequent,
Unpacking unloader is every just to need replacing cutter after a period of use.Cutter is fixed on the mechanism that unpacks by two bearing assemblies
In shell.Bale breaker case width is about 3 meters or so, and cutter installation axle is mounted in the root long axis in casing, it penetrates through machine
It crosses shell to be mounted on the device panel of two sides, both ends are fixed by bearing assembly.Bearing assembly is mounted on outside casing, installation axle one
End is provided with driving motor.This existing integral type installation axle, cutter are set on the mounting shaft.Cutter is being needed to replace
When, it needs first to remove driving motor, then remove the bearing assembly of two sides respectively, finally integrally removes installation axle, Cai Nenggeng
Change cutter.Since the consumption of cutter is than very fast, replacement frequency is high, therefore this structure expend replacement this work of cutter
Plenty of time.
Utility model content
The utility model makes the workpiece to be dismounted when the replacement of cutter too many for cutter mounting structure in the prior art,
It takes considerable time, ineffective problem, a kind of new cutter installation axle construction is provided, the mesh of simplified cutter dismounting is reached
's.
For achieving the above object, the technological means that the utility model uses is:
A kind of full-automatic unpacking unloader cutter installation axle, including the cutter fixed axostyle for installing cutter, cutter is solid
Dead axle bar one end is equipped with driving motor, and cutter fixed axostyle is made of the fixed shaft part in left side, the fixed shaft part in right side and intermediate shaft part,
The fixed shaft part in left side is connected on unpacking unloader casing by bearing assembly, and the fixed shaft part in right side is connected to by mounting assembly
On casing；Cutter is fixedly installed on intermediate shaft part, shaft part, right side are fixed with left side respectively by shaft coupling in intermediate shaft part both ends
Fixed shaft part is affixed.
After the completion of the utility model transformation, replacement cutter only needs to be removed intermediate shaft part, effectively subtracts
Maintenance duration is lacked.
Detailed description of the invention
The original cutter installation diagram of Fig. 1；
The improved cutter installation diagram of Fig. 2.
Specific embodiment
The embodiment of the utility model is described in detail with reference to the accompanying drawing:
As shown in Fig. 2, a kind of full-automatic unpacking unloader cutter installation axle, including the cutter fixing axle for installing cutter
Bar 3,3 one end of cutter fixed axostyle are equipped with driving motor 1, and cutter fixed axostyle 3 is by the fixed shaft part 31 in left side, the fixed shaft part in right side
33 form with intermediate shaft part 32, and the fixed shaft part 31 in left side is connected on unpacking unloader casing 6 by bearing assembly 2, and right side is solid
Dead axle section 33 is connected to 6 on casing by mounting assembly 5；Cutter 4,32 liang of intermediate shaft part are fixedly installed on intermediate shaft part 32
End is affixed with the fixed shaft part 31 in left side, the fixed shaft part 33 in right side respectively by shaft coupling 7.
The structure of existing cutter installation axle as shown in Figure 1, cutter fixed axostyle 3 are a whole shafts, and this programme improves structure
Think of is to carry out seperated transformation to cutter installation axle construction under the premise of maintaining the global shape of existing cutter installation axle.It is installed
Structure and size size does not change.Therefore, new cutter installation axle 3 is still applied to existing equipment shell and matches original size.
Cutter provided by the utility model installs axle construction, and the process for carrying out cutter replacement is: firstly, removing intermediate shaft part
The shaft coupling 7 at 32 both ends removes intermediate shaft part 32；Then cutter 4 is removed from intermediate shaft part 32；Then new cutter is installed
4, return dress shaft coupling 7.
It can be seen that the workpiece that needs dismount when cutter is replaced only relates to the axis of cutter installation section after the utility model transformation
Section, the mounting assembly of entire installation axle, driving motor remain stationary.Opposite with the workpiece that original dismounting is related to, this is practical new
Type obviously can save the extensive work time.
This programme economic benefit: this improvement, which avoids replacement cutter, must dismantle the disadvantage of bearing assembly, driving motor,
Bearing is replaced when having saved maintenance and sets up 20,000 yuan/time of scaffold expense, has saved 3 days/time of the repair time.This improvement extends
The service life of bearing assembly shortens the cutter replacement duration, ensure that the full-automatic unpacking unloader of urea puts into operation in time.
