Technical field
The invention belongs to pelletizing production technical field, resets more particularly, to a kind of drying grate with malfunction monitoring and fills
Put.
Background technology
Drying grate is the visual plant of pelletizing production, for being dried to green-ball and preheating procedure.Grate is drying grate
Core component, in grate the material of institute's cloth whether uniformly directly affect its be dried and preheat effect.Chain grate machine is adopted
Structure be that some grate plates and chain link are installed with little axle.Under normal work, grate plate typically can automatically reset by self gravitation, but
When breaking down, grate plate can not reset（Bypass grate plate afterbody after tail wheel still to tilt）, cause green-ball to fall problematic grate plate
When upper, green-ball can occur material leakage, affect the stable and pellet product quality of heat power engineering system, even more serious, the grate plate of tilting
Other parts can be collided in running and cause stopping accident.
The failure condition for being typically unable to normal reset is divided into following several situations, one be accompany between grate plate and chain link it is little
Ball；Or because the little axle of the reason drying grate such as thermal expansion, stressing conditions are bad there occurs plastic deformation；Besides grate plate occurs
Deformation.
As shown in figure 1, existing drying grate resetting means is near drying grate tail wheel, by the reset dress being fixed in frame
Putting the grate plate to breaking down carries out forced resetting.This fixed reset roller Jing often not only can not flexibly and effectively reset,
And out of order mode can not be screened and the particular location of the grate plate that breaks down is detected.In addition, this resetting means is not due to having
There is monitoring device, special operator on duty need to be arranged to be monitored, discovery carries out artificial percussion and resets after not resetting, this backwardness
The mode of production does not meet the requirement of efficient production with the management of modernization steel industry.

Gap W, described bearing assembly includes bearing and bearing spider, and described steel wire rope is connected with described connecting bracket,
Described monitoring device includes the support being arranged between the bearing spider of the reset roller I and the connecting bracket
Device, the pressure transducer being arranged between the bearing spider of the reset roller I and the connecting bracket, is arranged on drying grate tail
Grating sensor in portion's frame, described support meanss include compression spring, and this compression spring is connected to into the reset roller I
Bearing spider and the connecting bracket on stud.
Described bearing is rolling bearing.
Described reset roller I and the length of reset roller II >=grate width.
Advantages of the present invention：
The drying grate resetting means with malfunction monitoring of the present invention has good operability, by failure real-time monitoring
The reliability of system is increased, classification early warning is carried out to failure, be easy to fixing a breakdown promptly and accurately, improve mechanical efficiency,
Reduce labor intensity.
Description of the drawings
Fig. 1 is the structural representation of prior art drying grate resetting means.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is the A-A views of Fig. 2 of the present invention.
Fig. 4 is the I portions zoomed-in view of Fig. 3 of the present invention.
Specific embodiment
The specific embodiment of the present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 2,3 and 4, the drying grate resetting means with malfunction monitoring of the present invention, including reset press-roller device,
It is characterized in that steel wire rope 1 is connected with this reset press-roller device, and this steel wire rope 1 is lifted in drying grate frame, it is described
Monitoring device is additionally provided with reset press-roller device,
Described reset press-roller device includes connecting bracket 7, is rotated with this connecting bracket 7 respectively by bearing assembly and is connected
The 4a of reset roller I and the 4b of reset roller II, the described 4a of reset roller I and the 4b of reset roller II be arranged in parallel, and the 4a of reset roller I and reset
Leave gap W between the 4b of roller II, described bearing assembly includes bearing and bearing spider, described steel wire rope 1 and described company
Connect support 7 to be connected,
Described monitoring device includes being arranged between the bearing spider of the 4a of reset roller I and the connecting bracket 7
Support meanss 6, the pressure transducer 5 being arranged between the bearing spider of the 4a of reset roller I and the connecting bracket 7 is arranged
Grating sensor 3 in drying grate afterbody frame, described support meanss 6 include compression spring, by this compression spring connection
Stud on the bearing spider and the connecting bracket 7 of the 4a of reset roller I.
Described bearing is rolling bearing.
The described 4a of reset roller I and the length >=grate width of the 4b of reset roller II.
Present invention invention provides the drying grate resetting means with malfunction monitoring, including connecting bracket 7 and is arranged at connection
A pair of 4a of reset roller I on support 7, the 4b of reset roller II, steel wire rope 1, pressure transducer 5 and grating sensor 3 etc..Described steel
One end of cord 1 is fixed in drying grate frame, the hanging of whole resetting means is connected, the adjustable in length of steel wire rope 1, to adapt to
The flexible swing of grate, it is to avoid " other strength " phenomenon of fixed reset.
During drying grate runs, the grate plate 2 for going wrong cannot rely on self gravitation reset, as operation chain is worn
Enter to reset the 4a of roller I and the 4b of reset roller II, i.e. grate plate 2 through leave gap W the 4a of reset roller I and the 4b of reset roller II when, grate plate 2
It is ideal position by " combing " by the clamping action of roller（As shown in Figure 1）, that is, realize the forced resetting of grate plate 2.
The 4a of reset roller I and the 4b length of reset roller II >=grate width, are effectively ensured all grate plates 2 on width and are extruded
Reset.Using reset idler structure, the collision of grate plate 2 that can be to not resetting is entered row buffering, to grate plate 2 certain protection is played
Effect.
After the 4b of reset roller II is connected with connecting bracket 7, arranges between the bearing block 8 and connecting bracket 7 of the 4a of reset roller I and prop up
Support arrangement 6（It is made up of studs and compression spring）With pressure transducer 5, so when the grate plate 2 for being unable to normal reset is passed through
Resetting means, that is, when there is " other strength ", there is exception in the pressure signal of the detection of pressure transducer 5, will send early warning.
The structure that chain grate machine is adopted is that some grate plates 2 and chain link are installed with little axle, and to drying grate the every of grate is run
One group of little axle 9 is numbered, and the numbering of the little axle 9 for passing through every time is recorded by grating sensor 3, so when pressure transducer 5
It was found that when being unable to the grate plate 2 of normal reset, the corresponding numbering of little axle 9 is recorded, grating sensor 3 and pressure transducer 5
The co-ordination real-time monitoring of realizing when breaking down, it is to avoid artificial monitoring, save man power and material.
By the record to grating sensor 3, the situation that chain is unable to normal reset is relatively run per order of classes or grades at school, if same volume
Little axle 9 under number finds to be unable to normal reset when passing through resetting means every time, then prompting is because little axle 9 bends or grate plate
2 deform what is caused, point out to be overhauled；, whereas if the little axle 9 for being unable to normal reset numbers random appearance, then show
It is to be unable to normal reset due to what folder ball caused, by the squeezing action of this resetting means, folder ball can be cleared up effectively.
The present invention has good operability, and by failure real-time monitoring the reliability of system is increased, and failure is carried out
Classification early warning, is easy to fixing a breakdown promptly and accurately, improves mechanical efficiency, reduces labor intensity.
