Description
Technical field
The utility model is related to film line, particularly a kind of negative pressure instillation wet type self-cleaning and interval hydrojet self-cleaning
Chiller system.
Background technology
At present, the known auxiliary extruder vacuum system of PET film production line is by vacuum (-tight) housing, cooler, filter, Roots
Blower fan, oil water separator, screw pump, connecting tube and solenoid valve block into.It is right in the operating temperature of 270 DEG C of auxiliary extruder system
Evaporated in the melt and dissolved material of phthalic acid ethylene glycol fat, the mixed gas with small molecule and vapor as main component, by vacuum
The vacuum (-tight) housing of system is actively incubated connecting tube to 250 DEG C through electrical heating, is cooled down into cooler, the mixed air after cooling
The connecting tube and magnetic valve that body is incubated through the active of electrical heating to 180 DEG C again enter filter, and filter flow channel cross-section product is prominent
So increase, reduced velocity flow, filter mixes gas natural cooling without Insulation, and temperature further declines, in mixed gas
Small molecule is condensed into tiny free state dust, and filters off in the filter, and remaining main component is the gaseous mixture of vapor
Body is connected by connecting tube and magnetic valve with roots blower, and vacuumizing power by roots blower offer one-level is aspirated, gas warp
Water-cooling type oil separator oil-water separation, then through screw pump provide two grades vacuumize power isolated at suction profit after discharge.Vacuum
The pressure of system is absolute pressure 5mbar, and about 0.005 atmospheric pressure, i.e., -0.995 vacuum of atmospheric pressure is come with this
Impurity in the melt and dissolved material of auxiliary extruder is removed, is ensured for production line downstream process provides reliable production.
The design structure and operation principle of wherein cooler be：Cooler is cooled down with inside center coldplate, and is shunted
Gas, changes the flow direction of gas, and circular outer wall is the active insulation that electricity consumption is heated to 180 DEG C.Top is flange connection
Round end cap is sealed, and has cooling water inlet/outlet pipe to couple on end cap, and is connected with the inside center coldplate of cooler, inseparable
From.Bottom is the liquid collecting bucket of flange connection, and discharging tube and connection valve are arranged at liquid collecting bucket bottom, and the gas flow section of cooler is narrow
Narrow, the gas flow section with turnover cooler connecting tube is suitable, and very fast gas flow rate is formed with this.Mixed gas are entering cold
But device cool down when, water vapor condensation Cheng Shui falls into liquid collecting bucket, and small molecule is condensed into tiny free state dust, follow flow velocity compared with
Fast gas, the connecting tube and magnetic valve being incubated through the active of electrical heating to 220 DEG C enters filter.
But, under vacuum system 5mbar absolute pressures, negative pressure makes 270 DEG C in auxiliary extruder system of terephthalic acid (TPA)
Macromolecular gasification point in the melt and dissolved material of ethylene glycol fat is reduced and evaporated, this cause mixed gas composition be not only small molecule and
Vapor, also a small amount of macromolecular.When mixed gas containing gasification macromolecular enter cooler, gaseous macromolecular solidification
Zero point is high, and in the cooler by 180 DEG C, rapid condensation is into solid.Because gas flow rate is fast, circular outer wall is electricity
Heating is actively incubated, small with the mixed gas temperature difference, therefore, coldplate contact in molecule Shi centers is frozen into solid, from level to level
Condensation attachment cooler inwall, constantly reduces cooling effect of cooler, until blocking cooler.Contact solidification attachment from level to level
Dirt, close structure, quality are solid.Blocked cooler changes the flow regime of mixing gas and cooler is lost work
Make function, until blocking cooler gas runner.Prevent vacuum system from working, influence production run.
For the production of production line downstream process provides reliable guarantee, often to stop production line and clear up what is blocked by contamination by machine maintenance
Inside cooler, because top end cover is connected with the inside center coldplate of cooler, structure bulky is not easy to remove.Use
Cucurbit suspender is pulled out, but has close structure, big adhesive force pollutant contact solidification attachment, can also be difficult to pull out.Therefore from cold
But dismounting cleaning cooler in plate top is time-consuming, laborious.So, machine maintenance typically in cleaning, can only pull down the cooler collection of heaviness
Liquid bucket, is cleared up from bottom.The cooler bottom terrain clearance for pulling down cooler liquid collecting bucket is small, is shorter than the long and narrow gas of cooler
Runner, therefore when being cleared up with simple tools such as round steel, it is impossible to it is cleaned to the long and narrow gas flow top of cooler.Machine repair personnel
Thin round steel or thin band iron can only be used, the simple tool that can be bent by force with hand increases cleaning length, cleaning is reached cooler
Long and narrow gas flow top.But to smash the solid dirt of close structure, quality to pieces with these intensity differences, having many bends or curves simple tool
Dye thing, the long and narrow gas flow of the clean cooler of thorough cleaning is highly difficult, therefore the speed of machine maintenance cleaning cooler is slow, efficiency
It is very low.Again because the cooler bottom terrain clearance for pulling down cooler liquid collecting bucket is small, machine repair personnel cannot direct mesh in cleaning
Depending on observation, flashlight from the cooler irradiated for pulling down cooler liquid collecting bucket can only be used, from the porch that cooler is opened
During observation torch light irradiation, light leak situation when by gas flow judges the degree of cooler cleaning, therefore, cooler
The degree of cleaning out cannot be grasped directly.So after machine maintenance cleaning cooler, the long and narrow gas flow of cooler is nor clean
, simply gas flow is unimpeded.Such cooler has appeared its design defect in cleaning, lacks effective cleaning, sees
Examine working space.Clear up cooler speed is slow, efficiency is low, pay off unclean.The circular outer wall of cooler is that electricity consumption is heated to
120 DEG C of active insulation is collided with each other with the refrigerating function of cooler, wastes electric energy.PET production lines have two auxiliary extruders, often
The auxiliary extruder of platform respectively has a set of pumped vacuum systems, and often cover pumped vacuum systems has two sets of cooling systems again, and a production line has four
Cooler.When cooler is cleared up in daily machine maintenance, four coolers can all have different degrees of blocking, therefore, four coolers
Need to clear up simultaneously.Time-consuming, laborious during cleaning cooler, a machine repair personnel clears up a cooler needs 2-3 hours, even if
Four machine repair personnels, four coolers are cleared up and are also sought after 2-3 hours simultaneously, could clear up completion.Clear up the cold of vacuum system
But device must stop to give birth to line, and PET production line day shifts only have four machine repair personnels, and the machine maintenance human resources of occupancy are more and clearance time
It is long, increase downtime, have impact on production efficiency.
