It is connected with the inner wall of movable mold.To realize the close contact fixed between die body and movable mold, at the both ends of movable mold
Equipped with inserted block 984, inserted block and the slot on fixed die body are mating.Fixed die body, movable mold and slide constitute lower die.
As shown in figure 21, it is equipped with down pressing oil cylinder 99 in the front side of material blanking tube, upper mold 991 is fixed on the piston rod of down pressing oil cylinder, on
Mould realizes the compacting to briquette with lower die cooperation, by movable mold after being taken out in fixed die body, can take out the briquette being pressed into.
When being detected to coal sample, the multiple coal cinders extracted from each batch coal sample can be crushed one by one, be ground
To coal dust, then briquette is made in the coal dust of desired weight from the coal dust that each coal cinder attrition grinding obtains, and utilizes laser
Induced spectral analysis technology detects each briquette, and then obtains the coal data of entire coal sample, and briquette is corresponded with coal cinder at this time.
In addition, also can one by one crush, grind to the coal cinder extracted in each batch coal sample, then obtained from each coal cinder attrition grinding
Coal dust in respectively measure a part, the coal dust of measurement is mixed, a briquette is made, which is detected, into
And the coal data of entire coal sample is obtained, the briquette is that a part is respectively taken to be made from multiple coal cinders at this time.As shown in figure 18, enter
Mouth is different from the relative position of distributor, falls just different in the first storage chamber and the coal dust volume in second memory.Work as distribution
When device is kept right relatively, the coal dust volume fallen in the first storage chamber is more；When distributor is opposite to keep left, fall in the second storage chamber
In coal dust volume it is more；When distributor is relatively placed in the middle, fall big in the first storage chamber and the coal dust volume in the second storage chamber
Body is suitable.
When needing respectively to take a part that a briquette is made from multiple coal cinders, it may make distributor is opposite to keep right, fall in this way
Coal dust small volume in the second storage chamber, the second stripper of driving is opened so that the coal dust in the second storage chamber is fallen in lower die
In.After an each pair of coal cinder crushes grinding, just there is the coal dust of certain volume to enter in lower die, each coal coal dust mixing in the block
After a briquette is made.
When crushing grinding to each coal cinder briquette being respectively prepared, the coal dust volume fallen in the first storage chamber is opposite
It is more, the first stripper is opened at this time so that enough coal dusts are fallen in lower die in the first storage chamber, then carry out punching press to it
Obtain briquette.Down pressing oil cylinder drives upper mold to complete counteragent after cake of press operation so that upper mold is removed from lower die, and the 4th is electronic
Telescopic rod continues action so that slide passes through outlet to stretch out rack.
