Description
Technical field
The utility model relates to a kind of offset printing tusche anti-clogging delivery system, belongs to offset printing tusche production technical field.
Background technology
Main pigment in tusche is carbon black, and carbon black is the material that a kind of specific surface area is larger, and this has just caused carbon black to have higher oil absorption; And the viscosity of the common resin used of offset ink is all higher, therefore the overall flow of offset printing tusche is not very good, especially be embodied in the just scattered stage of also not grinding of material, there is no flowing power if be very easy to " freezing " in the situation that winter, temperature was low.For small-sized ink factory, the each output of producing of offset printing tusche is little, completely by manually make material disperse and grinding step in shift, be production efficiency compared with low and do not have a large problem.But for large-scale ink factory, due to several tons easily of the each productive outputs of offset printing tusche, therefore each inter process material is pipeline conveying, just scattered offset ink is because the temperature of dispersion step high shear force meeting improving material, so or be transported to and grind storage cylinder by pipeline than being easier to, if but encounter feed pump fault or other reasons can not be in time by scattered mass transport when grinding storage cylinder, along with the decline of temperature of charge, flowing power meeting variation, therefore running into this situation in winter is very easy to disperseing cylinder and grinds the problem that tusche obstruction delivery duct occurs between storage cylinder.The utility model solves this problem by the anti-clogging delivery system that designs a kind of offset printing tusche.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of offset printing tusche anti-clogging delivery system is provided.
The utility model solves the technical scheme that its technical matters adopts:
Offset printing tusche anti-clogging delivery system, comprise the dispersion cylinder, feed pump and the grinding storage cylinder that connect successively by conveying pipeline, disperse the outlet of cylinder and the import of grinding storage cylinder to be equipped with control cock, also comprise PLC controller, be located at and disperse the transition tank between cylinder and feed pump and be located at feed pump and grind the pressure sensor on the conveying pipeline between storage cylinder, the top of described transition tank is also fixed with the oiling bucket with control cock, the signal output part of described pressure sensor is connected with PLC controller by data line, and the control circuit of feed pump is connected with PLC controller.
The utility model is mainly by disperseing cylinder, transition tank, oiling bucket, grinding storage cylinder, conveying pipeline, feed pump, pressure sensor, control cock and PLC controller to form.When the utility model normally moves, just disperse complete offset printing tusche material to arrive and grind storage cylinder by transition tank smoothly by the drive meeting of feed pump; When at temperature compared with under low condition, midway feed pump break down or subsequent handling break down cause conveying suspend, so most of offset printing tusche material can stop and freeze in transition tank, if now fault is got rid of, in can struggling against by oiling, add a part of solvent naphtha to dissolve the offset printing tusche material freezing, increase its flowing power, after material fluidity recovers, restart feed pump conveying; The effect that pressure sensor is set is the running of monitoring delivery system, sets in advance the bound of conveying pipeline pressure, and in the time that grinding storage cylinder has been expired, pressure increases to reach gradually prescribes a time limit, and PLC controller control feed pump auto-stop, prevents that feed pump from burning; In the time disperseing cylinder to occur to stop up in without offset printing tusche material or transition tank, pressure declines gradually and reaches lower limit, and now PLC controller can be controlled feed pump and shuts down, in order to avoid feed pump idle running, the energy avoids waste.
As preferably, described transition tank is also provided with for the heat exchange structure to offset ink heating by hot water or steam, and described heat exchange structure is outer coil pipe or chuck, and the capacity of transition tank is to disperse 3 ~ 5% of cylinder capacity.Although by oiling struggle against add solvent naphtha can dissolve to a certain extent the offset printing tusche material freezing, increase its flowing power, but when breaking down overlong time, while freezing too seriously, the efficiency that interpolation solvent naphtha thaws is too low, likely need a large amount of solvent naphthas, for this reason, transition tank arranges outer coil pipe or chuck, the thawing with quickening offset ink by steam or hot water heating, can enhance productivity, save the use amount of solvent naphtha.
As preferably, described PLC controller is also connected with warning device, and described warning device adopts audible-visual alarm lamp.By use of the present utility model, can improve the degree of automation of offset ink mass transport, reduce operator's labour intensity, monitor the operation of delivery system by the pressure sensor and the PLC controller that arrange, the pressure signal detecting when pressure sensor is when abnormal, can control closing of feed pump by PLC controller, can remind operator by warning device, so that the timely trouble-shooting of operator simultaneously.
The beneficial effects of the utility model are:
First, existing offset printing tusche is produced the pipe-line transportation system between dispersion step and grinding step, not anti-blockage function, only have just scattered material and there is higher temperature and good flowing power, just carry than being easier to, but in the time that winter, temperature was low, run into accident as feed pump fault or power failure etc., the probability of offset printing tusche feed blocking pipeline is larger, by a transition tank is set between delivery pipe, in the time there is transmission failure, material concentrates on transition tank mostly, on transition tank, there is the bucket of oiling, in the time that freezing, material can add the solvent naphtha that recovers to increase its flowing power, thereby dissolve latch up phenomenon generation, heat by the outer coil pipe of transition tank in addition, can accelerate to thaw, enhance productivity, secondly, on the delivery pipe that enters grinding storage cylinder, a pressure sensor is set, by the running of pressure sensor and PLC controller monitoring delivery system, has improved automatization level of the present utility model, can guarantee the timely eliminating of fault, extend service life of the present utility model.
