Description
Technical field
The utility model belongs to the quality of green pellets pick-up unit in the pellet forming process, refers to a kind of compression strength of green pel let pick-up unit particularly.
Background technology
The quality of green pellets evaluation mainly contains following index: the drop number of green-ball, the compressive strength of green-ball, exposing to the sun of green-ball are split temperature etc.Quality of green pellets is relevant with the quality and the quantity of balling equipment, pellet forming process, green-ball water cut, institute's adding additives, it all has a direct impact ring formation in combustion atmosphere, the kiln in follow-up stoving process, roasting technique, the kiln etc., thus quality of green pellets to detect be the important means that instructs pellet forming process.At present, it is firmly to press down green-ball by artificial with iron plate on the electronic balance of horizontal positioned that compression strength of green pel let is detected, and when sphere is broken, reads institute and exert pressure size as the maximum compressive strength of green-ball on balance.Mainly there are two problems in this traditional detection method: one is manually on balance green-ball to be exerted pressure, and the direction of the power that applies is wayward, and the pressure that balance is experienced also not exclusively is the actual suffered pressure of green-ball; Another is that each detects workman to determining the green-ball judgement difference of broken moment, thereby the randomness of value is very big as a result to cause check and analysis, so the testing result reliability of existing detection technique is very poor.
The inventor finds have directly between depression distance during pressurized and green-ball vary in diameter and the impaired deformation quantity of green-ball and get in touch in for a long time to the compression strength of green pel let test experience, as shown in table 1.
Table 1:
| Depression distance and vary in diameter amount | The impaired deformation situation of green-ball |
| Depression distance is a |
Deformation only takes place and does not break in green-ball. |
| Depression distance is a |
Green-ball breaks, and crackle appears in the surface. |
| Depression distance is a |
Green-ball breaks, and surface crack magnifies. |
| Depression distance is a |
Green-ball is broken fully. |
The inventor selects 10 groups of experiment green-balls, and the variation relation during with its pressurized between depression distance and the green-ball stress value (N) is listed table 2 in.
Table 2:
Variation relation as shown in Figure 1 between depression distance in the above-mentioned testing result and green-ball were stressed, promptly, pressure constantly changes along with constantly increasing the impaired deformation quantity of green-ball green-ball, there is a peak value at the pressure place when green-ball deformation reaches 1/4 diameter, and this moment, fragmentation took place the green-ball pelletizing, and crackle appears in the surface; Stressed size is in slow decline during from 1/4 diameter to 1/2 diameter in the deformation of green-ball pelletizing, and the green-ball degree of crushing is strengthened, surface crack strengthens, and is to the last broken fully.This shows that what this peak value was shown promptly is the maximum pressure that green-ball can bear, i.e. force value maximum of being born when green-ball deformation is 1/4 diameter place.
Summary of the invention
The purpose of this utility model will provide a kind of easy to operate, testing result compression strength of green pel let pick-up unit accurately exactly.
For achieving the above object, a kind of compression strength of green pel let pick-up unit of the present utility model, it comprises: horizontal base, described horizontal base is provided with electronic balance, described electronic balance is provided with the green-ball retainer plate, its special character is: the depression bar support arm also is installed on the described horizontal base, is fixed with the depression bar sleeve that is positioned at green-ball retainer plate top on the described depression bar support arm, but be provided with vertical moving in the described depression bar sleeve and aim at the pressure head link rod at green-ball retainer plate center; The upper end of described pressure head link rod is provided with pointer, and the scale that matches with pointer is set on the described depression bar support arm; The lower end of described pressure head link rod is provided with the green-ball pressure head, and the pressure head link rod of described green-ball pressure head upper end is provided with operating grip.
Further, described depression bar support arm is made of vertical support frame that is arranged on the electronic balance both sides and the whippletree that is fixedly connected between the vertical support frame of both sides, and described depression bar sleeve is fixed on the whippletree, and described scale is fixed therein on the vertical support frame.
Further, described pressure head link rod is provided with the spacing bayonet socket that matches with spacing card, when described spacing bayonet socket is positioned at depression bar sleeve top, the pressure head link rod can be positioned in the described depression bar sleeve by inserting spacing card, thereby makes the green-ball pressure head rest on green-ball retainer plate top.
Again further, described scale is provided with the slip indicator dog.
The utility model by described pressure head link rod is vertically set on described green-ball retainer plate directly over, when the detection workman firmly evenly presses down operating grip, the pressure direction that is pressed on the green-ball is vertical with the position of green-ball, and the reading on the electronic balance just can embody the size of green-ball pressure exactly like this.Simultaneously, described pressure head link rod upper end is provided with pointer, in conjunction with the scale on the depression bar support arm, can indicate the relation between green-ball stress and deformation amount and its diameter, thereby accurately determines broken moment of green-ball and accurately determine the compression strength of green pel let value.
