Brief description of the drawings
Fig. 1 is the structural representation for the experimental provision for simulating and detecting the abrasion of silo wall.
Embodiment
With reference to Fig. 1, a kind of simulation and the experimental provision for detecting the abrasion of silo wall, mainly by detecting silo wall sample surface
Dynamic friction factor and long duration of action under mass change realize.Including clinker storehouse 1, detector bar 2, silo wall sample 3,
Piston plate 5, workbench 6, supporting table 7, discharge plate 10, connecting rod 8, drive 9, motor 11 and driving belt 12；Detector bar 2
The inwall of clinker storehouse 1 is arranged on, the side of clinker storehouse 1, which is provided with opening, opening, sets silo wall sample 3；The piston plate 5 is arranged on
The bottom of clinker storehouse 1, piston plate 5, which is provided with opening, opening, sets discharge plate 10；Clinker storehouse 1 is arranged on workbench 6, work
Make platform 6 to be arranged in supporting table 7；
Clinker 4 loads clinker storehouse 1 by the opening on the top of clinker storehouse 1, and whole experimental provision provides power by motor 11,
Drive 9 is imparted power to by driving belt 12 again, then piston plate 5 is driven by connecting rod 8, it is axially done along clinker storehouse 1
Move back and forth.During piston plate 5 is moved, clinker is driven constantly friction detector bar 2 and silo wall sample 3,
The clinker inside discharge plate 10, clinker storehouse 1 is directly rotated after off-test with regard to that can be automatically drained out.It is living after first addition clinker
Seben is just moved back and forth, and subsequent process just without adding clinker again, until experiment terminates.
Further, connected between clinker storehouse 1 and workbench 6 by detachable apparatus.
Further, connected between workbench 6 and supporting table 7 by chute, between changing between the workbench of both sides
Away from.Therefore the diameter in clinker storehouse 1 can be changed by the relative position of workbench 6 and supporting table 7, then change the work of respective diameters
Seben 5 can simulate the silo abrasion under different ratio of height to diameters.
Further, detector bar 2 is connected with clinker storehouse 1 using fixture, therefore detector bar 2 can be separated into clinker storehouse 1.Cylinder
Bulkhead sample 3 is easy to disassemble, and its abrasion condition is detected after can at a time suspending experiment, thus can detect
The wear condition of each period in whole working condition.
Further, detector bar 2 has been provided opposite in silo wall sample, has been made up of the pig iron, thickness is about 0.5mm, is used for
To under long-time rubbing action to the comparative observation of silo wall sample 3.
With reference to specific embodiment, the invention will be further described.
Embodiment 1
A kind of experimental provision for detecting silo bulkhead abrasion condition, including clinker storehouse 1, detector bar 2, silo wall sample 3, work
Seben 5, workbench 6, supporting table 7, motor 11, belt 12, drive 9, connecting rod 8 and discharge plate 10.
Clinker storehouse 1 is located at the top of workbench 6, is fixed by the card article of workbench 6.At the same time supporting table 7 and work
Make to be connected with each other by chute between platform 6, therefore can be by changing the spacing between the workbench of both sides and then changing both sides card
Relative distance between bar, enables to realize different ratio of height to diameters.
Clinker 4 is inserted from the upper opening in clinker storehouse 1, and motor 11 imparts power to drive 9 by belt 12, enters
And by connecting rod 8 drive piston plate 5 pump so that clinker about 4 continuous friction cylinder bulkhead sample 3 with
And detector bar 2, its degree of wear can be detected by the dynamic friction factor of measuring cylinder bulkhead sample 3 under shortterm effect.If
Under long duration of action, the inner surface of silo wall sample 3 necessarily reaches certain smooth degree, and now surveying its dynamic friction factor again can not
Effectively reflect its degree of wear, so then the weight change of the weight knots modification of measuring cylinder bulkhead sample 3, now silo wall
Amount just can be good at reflecting its degree of wear.
Embodiment 2
A kind of experimental provision simulated and detect silo bulkhead and clinker abrasion condition, including clinker storehouse 1, detector bar 2, cylinder
Bulkhead sample 3, piston plate 5, workbench 6, supporting table 7, motor 11, belt 12, drive 9, connecting rod 8 and discharge plate 10.
Clinker is located in the clinker storehouse 1, is inserted by the opening on the top of clinker storehouse 1, and motor 9 will be dynamic by belt 12
Power passes to drive 9, and meeting drivening rod 8 is moved after drive is rotated, and then piston plate 5 is pumped, at this
During individual, clinker will continuous friction cylinder bulkhead sample 3 and detector bar 2 up and down, thus simulate silo loading and unloading
When working condition.For the detection of friction condition in the short time, realized by the dynamic friction factor of measuring cylinder bulkhead sample 3
's.And under prolonged rubbing action, the surface dynamic friction factor of silo wall sample 3 necessarily keeps stable, now measure again
Its dynamic friction factor then can not effectively draw the abrasion condition of silo wall sample, therefore now just measure the change of its weight
Amount, so as to draw its wear condition.
Silo wall sample 3 selected by the present embodiment is C30 concrete arc-shaped plates, length 500mm, width 30mm, thickness
10mm, simultaneous with certain radian, can mutually be connected with clinker storehouse 1, and the clinker added in clinker storehouse 1 is common in the market
PC32.5 clinkers.The initial dynamic friction factor of silo wall sample 3 is recorded and then shown position is secured it to again,
The clinker of preparation is subsequently added, is checked after every preparation, opening the power supply of motor 11 makes experimental provision start working.
Power supply was closed every ten minutes in the incipient stage, opening discharge plate 10 releases clinker, then pull down silo wall sample 3 and measure its table
The dynamic friction factor and record in face, are so repeated five times, the dynamic friction factor of each gained is as shown in table 1.Simultaneously at the 5th time
Its quality is write down using electronic balance after unloading silo wall sample 3, is 347.8g.
Each stage silo wall sample dynamic friction factor of table 1
| Time (min) | 0 | 10 | 20 | 30 | 40 | 60 |
| Dynamic friction factor | 0.4528 | 0.4501 | 0.4493 | 0.4486 | 0.4431 | 0.4426 |
After five dynamic friction factors are recorded, start to detect abrasion feelings of the silo wall sample 3 under long-time rubbing action
Condition, therefore just stop experimental provision every a hour, then its quality is measured, the experimental data finally given is as shown in table 2.
Each stage quality of the silo wall sample of table 2
| Time (h) | 0 | 10 | 20 | 30 | 40 | 60 |
| Quality (g) | 347.5 | 346.9 | 346.4 | 346.0 | 345.5 | 345.1 |
Present invention is mainly used for simulation silo wall during loading and unloading, friction of the clinker to silo wall, Jin Erjian
Its abrasion condition is surveyed, and this device can not only detect the silo wall abrasion under short-term rubbing action, additionally it is possible to for a long time
Abrasion condition under effect is detected.
