Using above-mentioned technical proposal, the conduction oil that the present invention uses circulates what the coating in inner barrel was heated
Process is：Electrically heated rod exchange hot plate in conduction oil heated, oil circulating pump by exchange heat disk in high temperature conduction oil successively
Oil fuel tube is pumped into through return duct, oil guide pipe, high temperature heat conductive oil is upwardly into the equal stringing of conduction oil, conduction oil through oil fuel tube again
Be downwardly into by the circulation oilhole of the uniform bottom of the tube of conduction oil in toroidal cavity, at the same time, conduction oil in toroidal cavity by
Spill port at the top of heat exchange disk is flowed downwardly into the horizontal cavity of heat exchange disk, and electrically heated rod is to being flowed into leading in horizontal cavity
Deep fat carries out heat temperature raising, and under the swabbing action of oil circulating pump, high temperature heat conductive oil enters through back cavity, slotted eye and oil guide pipe again
Oil circulating pump, then enter toroidal cavity top through oil fuel tube and the equal stringing of conduction oil, so circulate always.
High temperature heat conductive oil in heat exchange disk with wear-resisting heat-conducting plate at the top of the disk that exchanges heat to the bottom in inner barrel by adding
Heat, the conduction oil of the interior circulation of toroidal cavity heat to the coating at the circumference in inner barrel, pass through adding for inner barrel bottom
Heat and the heating to inner barrel outer circumferential sides portion, it can be ensured that the uniformity of the paint heating temperature in inner barrel, it is ensured that interior
The coating of cylinder body bottom not incipient scorch, do not lump, the thawing speed and quality of coating are improved, so as to improve efficiency of construction.
While heating, reducing motor driving agitating shaft rotates, and the stirring vane on agitating shaft stirs the coating in inner barrel, also has
Help coating to be heated evenly, and avoid the coating of inner barrel bottom not incipient scorch, do not lump.
By using auto temperature controlled system, it is no longer necessary to the heating-up temperature of manual control electrically heated rod and oil circulating pump
Pump oil speed, it can be supervised in real time according to the temperature and coating material temperature sensor for the conduction oil that heat conduction oil temperature sensor monitors in real time
The heating power of temperature conditions adjust automatically electrically heated rod and the pump oil speed of oil circulating pump of the coating of survey, so as to reduce manpower
Cost, temperature control regulation are more accurate；Meanwhile can the different temperature control of sets itself for different types of coating, workmen
Scope processed, realize molten coating material temperature automatically control, more save, and ensure the thawing speed and quality of coating.
Coating is poured into by the charging groove portion of feed hopper, and coating is flowed into along the bottom of charging groove portion through pipe portion from high to low
Inside inner barrel, after coating is filled it up with, the opening in pipe portion is clogged using thermal insulation plug, improves heat insulation effect.In heating process,
Coating can produce flue gas after being heated, and flue gas is discharged by smoke exhaust pipe.It can be expanded during conduction oil is heated Posterior circle, conduction oil
Toroidal cavity can be full of, it is also possible to entered by overflow pipe in buffer tank, when the pressure in buffer tank reaches setting pressure,
Safety valve just plays depressurization, avoids the excessive damage inner barrel of pressure and outer cylinder body.
The seal operation principle of sealing structure：It is arranged on because oil fuel tube is coaxial inside oil return pipe, therefore in oil return pipe
Lower end is provided with the sealing structure being fastenedly connected with oil fuel tube, and sealing structure compresses the rubber of conical structure using top pressure nut
Sealing-plug, the lateral wall and madial wall of rubber seal plug be respectively arranged with crimped with oil return inside pipe wall sealing exterior seal ring and
The inner seal ring of sealing is crimped with oiling pipe outer wall, top pressure nut is tighter to rubber seal plug pressure, and sealing effectiveness is better.
Discharging is moved down by the way of crank handle, and by gear driving rack, rack drives striker plate along slide rail
It is dynamic, so as to block or open discharge nozzle.Discharge nozzle uses interior discharge nozzle and outer discharge nozzle, and coaxial by flange connection
To connection is detachably fixed, it can so facilitate the disassembly and installation of discharge nozzle and outer discharge nozzle in installation.First installing pipe and
The concrete structure of two installing pipes is identical with the structure of discharge nozzle, is saved using two, and coaxial removable by flange connection
Unload and be fixedly connected.
Into toroidal cavity and horizontal cavity, the process of addition conduction oil is：Safety valve is removed, from conduction oil inlet
Conduction oil is poured into buffer tank, conduction oil is flowed into toroidal cavity along overflow pipe, then is flowed to by return port in heat exchange disk,
After filling, safety valve is installed.When maintenance or when safeguarding, it is necessary to the conduction oil in toroidal cavity and horizontal cavity is discharged, open
Draining valve is opened, conduction oil is discharged from oil exit pipe.
Because discharge nozzle is arranged on the following side of inner barrel, coating by discharge nozzle when being discharged by toroidal cavity
The uniform heating of heat exchanger tube in high temperature heat conductive oil and heat exchange disk, the more uniform effect of heating is played to the coating of discharge.
The inwall sidepiece of shell body is detachably connected by trough plate and connecting plate.Outer cylinder body, inner barrel upper end edge are equal
Fix and be tightly connected with heat-insulated lid, inner barrel bottom is played a supporting role by column cylinder, and passes through interior discharge nozzle, first
Installing pipe and the second installing pipe are connected with outer cylinder body, so that inner barrel positions.
Electric control gear in the present invention refers to PLC, single-chip microcomputer or integrated circuit, is existing conventional techniques.
In summary, the present invention has advantages below：The total heating surface of coating can be made to accumulate larger and than more uniform, make painting
The thawing speed and quality of material are improved, so as to improve efficiency of construction；Part in the present invention can be changed, be easy to
The most easily damaged part of periodic replacement, extends complete machine service life, reduces cost；Using the hydronic mode of conduction oil,
And by automatically controlling, the energy is more saved, the heating quality of coating is also improved, and reduce human cost.
