After the completion of packing weighing, vacuumized, vacuum is as follows:
First according to the type of powdered activated carbon and weight, the number vacuumized is set on control device and is taken out every time true The time is dredged in empty time and blowback;
Then, controlling lifting cylinder 71 by control device drives pumping tracheae 73 to move downward, while being evacuated tracheae 73 It drives microporous pipe 74 to be passed down through the discharge port of charging basket 4, extend into always in activated carbon packaging bag 10, stop lifting cylinder 71 and transport It is dynamic;
Then, the control of control device 9 vacuumizes control valve opening, so that vacuum pump is vacuumized, passes through blowback Gas makes to be bonded in the plate active carbon around microporous pipe and falls off, and the active carbon to have agglomerated and powdered activated carbon AUTOMATIC ZONING do not have Under strong mixing, will not redisperse become the high powdered activated carbon of air content, agglomeration active carbon under the effect of gravity, sinks to bag Bottom, the light powdered activated carbon of density then float, and when next time is evacuated, the powdered activated carbon high to the air content floated to above is taken out Gas improves pumping efficiency, controls lifting cylinder 71 by control device and pumping tracheae 73 is driven to move upwards, while being evacuated tracheae 73 drive microporous pipes 74 move upwards, and the discharge port until being detached from lower part charging basket 4 so far just completes the process once vacuumized; It by repeating the above steps, is repeatedly evacuated, to reach the gas of discharge powdered activated carbon, reaches specified volume, specified Weight;After reaching the time of setting vacuumized, closing vacuumizes control valve;
After the process for completing once to vacuumize, blowback air, if microporous pipe is blocked, by microporous pipe dredger to micro- Hole pipe 74 realizes anti-gas dredging, while will also be bonded in active carbon hardened in microporous pipe and blowing off.
The gas in watertight aircase is controlled by control air shut-off valve to enter in the cylinder body of dredging cylinder, pushes piston, it is living The gas of the other side is pushed into microporous pipe 74 by plug by appendix, tamper under the action of high pressure gas in microporous pipe 74 It is rushed out, is bonded in the active carbon to agglomerate around microporous pipe and is rushed and fall;Certainly the micropore dredger in the present invention can also be adopted With the dredger of other inflatables;Because dredging gas and the gas flow vacuumized during dredging just on the contrary, institute To be referred to as anti-gas dredging.
Arrangement, the piston rod of the lifting cylinder and the upper end for being evacuated tracheae 73 connect the pumping tracheae 73 vertically It connects, the upper end of the pumping tracheae 73 is also connected to the appendix, and the lower end of the pumping tracheae 73 passes through 4 top of charging basket Mounting hole is connected to the upper end of the microporous pipe 74.
The netted pipe or micropore tank of micropore can be used in the microporous pipe 74.It can certainly can realize that pumping is true using other Empty microcellular structure.
The present invention reduces user equipment cost and Energy in use and dimension by mixing machine 1 directly feed, reduction conveying device Protect cost.
This packing machine is directly fed mode using mixing machine 1, no longer uses intermediate feeding device;Such as conveying screw rod, save Energy consumption is simultaneously and equipment cost, it is contemplated that different activities charcoals air content is different, while water content is different, viscosity is also different, is Enable and discharge quantity uniform, controllable and do not bond putty, therefore use double-valve structure, first baiting valve 13 of mixing machine is opened When, the second baiting valve 14 of mixing machine partially opens, and limits feeding speed and keeps uniform feeding, when the first blanking of mixing machine When valve 13 is closed, the second baiting valve 14 of mixing machine is fully open, it is possible to prevente effectively from when the first baiting valve of mixing machine 13 is closed, There is remaining material to remain between the first baiting valve 13 of mixing machine and the second baiting valve 14, is blocked when so as to cause feed next time.
In addition, higher packaging weighing precision is needed since active carbon factory meets the market demand, the active carbon of heterogeneity, Air content is different, and density or more different than volume, this results in traditional packaging weighing method to be difficult to meet user demand, the present invention It takes measures to reduce influence of the internal impact load to weighing precision in structure first:
(1) multisensor even support mensuration is used in structure, is reduced system and is arranged using lever-type sender When inside in folder bag and blanking dynamic impulsion variable the lever amplification of weighing precision is influenced
(2) cylinder folder bag method is proposed using two steps when folder bag, is further reduced influence of the folder bag shock loading to weighing accommodation zero when, Both when folder bag, first put on portion's short stroke folder bag cylinder, due to short stroke generate shock loading it is smaller, in addition can control make from Time when weighing accommodation zero is longer, thus it is smaller on actual weight influence when zero setting, meanwhile, upper part short stroke air cylinders are in place It postpones, then puts minister's stroke folder bag cylinder, at this moment can effectively slow down lower part long stroke cylinder by top short stroke air cylinders The long big shock loading generated of stroke influences weighing accommodation zero;
(3) using fastly plus baiting valve 31, slowly plus 32 blanking of baiting valve, blanking at the beginning when, open fastly plus baiting valve 31, fastly Fast blanking controls blanking screw rod conveying speed by control device 9, utilizes simultaneously when the close packaging rated value of dynamic weight Slowly add 32 blanking of baiting valve, so that discharge quantity and speed are controllable when blanking, lag weight and material block pair when reduction blanking is uneven Influence of the buckles at bag bottom to final weighing results.
The present invention takes off bag using two step cylinders, improves pick-up performance, reduces flour dust overflow amount;
